DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for constructing a wooden house which can be constructed in a one-story or a multi-storey wooden house with a short construction period and requires few materials, and which is excellent in strength.

[0002]

2. Description of the Related Art For wooden houses, the dimensions, arrangement and hanging method of building materials such as columns and beams are determined based on floor plans and floor plans based on the skills and experience acquired by carpenters themselves. A carpenter himself made a design on a board called a board, and according to the drawing, the carpenter himself cut a predetermined portion of various building materials to build a house. By the way, in recent years, the construction work has become so-called 3K work in which the contents of the work are dangerous, hard, and dirty, so the number of young craftsmen is decreasing year by year. With this, the aging of carpenters is increasing. I have. Despite this situation, the client of the house, in order to realize their comfortable living,
The demands for the building, such as the floor plan, are meticulous in detail, and the absolute number of young and talented carpenters who can meet it is reduced. Therefore, in recent years, as a construction method of a wooden house, a method of pre-cutting main building materials such as pillars and beams in a factory and carrying it to the site to assemble it has become widespread. Such a pre-cut technology is one in which a person who operates a CAD performs a structural design based on a floor plan in a factory in advance, and collectively processes building materials with various woodworking machines in accordance with this design drawing. It is intended to solve the recent shortage of carpenters, variations in structural design, and prolonged processing periods.

[0003] The structure of a conventional wooden house will be described below with reference to the drawings. FIG. 7 is a foundation plan of a conventional wooden house, and FIG. 8 is a side view of a main part of the conventional wooden house during construction. 100 is solid foundation, 101 is footing, 1
02 is a foundation beam for the outer periphery, 103 is a foundation beam for the opening that receives the column of the opening, 104 is a vent formed in the foundation beam 102, 105 is a floor beam for the second floor, and 105a is an opening for a large room or the like. high floor beam member RyoNaru d ₁ which is laterally placed is of 360mm in part, RyoNaru d 105b is that is laterally placed in an opening of a medium chamber
₂ is a floor beam member having a middle height of 270 mm, 105 c is a floor beam member having a beam height d ₃ of 180 mm and 10
6a, 106b and 106c are floor beam members 105a to 105a, respectively.
Tube pillars having different lengths depending on the beam structure of 05c, 107 is a vignetting blade, 108 is a corner pillar consisting of a through pillar, 109 is a bracing, 11
0 is a base part.

[0004] The specific dimensions of the floor beams on the second floor are 105 m in width.
m is common and the beam length is 105mm to 360mm
Up to 11 types, rarely 400 mm or 450
mm is used. Generally, pillars are 105mm
Cedar, cypress, Yonega, Yonematsu
Glued lumber (Yonetsuga, Yonematsu, spruce, etc.) is often used.
For example, as many as 60 to 80 pieces are cut into a house of 130 m ² , which is cut into mm to 2850 mm. In the case of a two-story house, a single long corner pillar having a normal length of 6 m, which is common to the second floor part, which is called a through pillar, is provided at a predetermined location. By the way, in the corner post, 105m
Dimensions of m × 105 mm to 135 mm × 135 mm are often used. Further, the floor beams on the second floor are assembled to the ceiling portion on the first floor, and the size of each floor portion of the opening on the first floor wall such as a sash frame portion, a door frame portion, and a sliding door portion is set. The height of the beam, which is the height of the floor beam, is partially varied depending on the size of the space inside the room.

[0005] In particular, in the case of a two-story house, what is most important in the design is the strength of the floor beam, and then the volume thereof. In other words, it is most important for carpenters and CAD entrepreneurs to determine the structure based on their skills and experience in view of their strength and volume, when designing the structure of a two-story house. Conventionally, based on the length between columns, how to apply a load from above, the magnitude of the force from the side, etc.
Usually, the beam structure of the floor beam, which is about one-tenth of the span to be incorporated, has been determined. As a result, in the case of a general wooden house, 5 to 8 types of floor beams having different heights are used per building. As a result, the length of the pipe column is different due to the difference in the beam structure, because the beam ends are aligned and stored at the site. As a result, various types of pipe columns having different lengths were required. In addition, the determination of the beam height of the hut beam supporting the roof also depends on the span between the columns supporting the beam, as in the case of the floor beam. The hut beams were connected to form a single hut beam. In addition, these various beams are also available in different types, such as Yonematsu, New Zealand pine,
Although pine-based materials such as ground pine are frequently used, wood produced in the local land such as ground cedar and ground cypress is used in some regions, as well as rice toga and glulam.

Next, a conventional method for constructing a wooden house will be described with reference to the drawings. In general, foundation work can be broadly divided into two types: cloth foundation and solid foundation. In recent years, factory production bases have been adopted to reflect the shortage of field workers. The foundation is laid on the bottom of a trench dug about 50 to 60 cm in width and about 20 to 30 cm in depth.
６０60 cm), and a concrete cloth foundation having a height of 40 to 60 cm and a width of 12 cm, which is said to be rising, is laid thereon. Depending on the condition of the ground, rebar may be inserted in the bottom and rise, or only in the bottom. The rises are designed so that they are all located where the pillars come from, but these rises and bottoms are designed to be almost continuous. In addition, the foundation of the construction method called solid foundation is not digging a groove like the above-mentioned cloth foundation, but instead of rubbing stones on the entire surface of the ground, a reinforced concrete board (thickness 10 to 20c)
m) is formed. The arrangement of the rising is the same as the cloth foundation and the design rule is also the same.
2 Total floor area according to the conventional design rule of about 150 meters ²
The average foundation length (total length of the rising portion) inside and outside the first floor area of 80 m ² in a multi-storey house is 80 to 85 m. The factory-produced PC foundation is similar to the cloth foundation, and the finished product is placed on the site with a crane.
However, the design rules are the same. In addition, the carpenter creates a cut-out drawing called a drawing board while taking into account the beam structure, the position of the columns, and the like in the plan view, and the wood is processed along the drawing. In this case, the carpenter decides the timber spine, pillar diameter, length, etc. based on his experience and budget. The budget rises in direct proportion to the volume. The basis of the structure design is the existence of each room. First, pillars are arranged on both sides of the outside opening, on both sides of the room opening, and on the boundary between rooms. The top of this pillar is connected with beams and girders. At this time, the beam structure is determined by the distance between the columns. Depending on the magnitude of the load on the second floor, this beam structure is adjusted. Also, depending on the budget, it may be designed with a bare beam or oversized. Also, depending on experience, an appropriate design or a fragile portion may occur. Although such a design method is generally known, it is rather difficult to do so without much experience because the color of the mouth is rather dark.
The base is usually 105 × 105, and each is joined by a joint called an ant. A tenon is machined at the position where the pillars are erected on the upper surface of the base. This is placed on the foundation and tied to the foundation and base with anchor bolts. Pillars and beams are assembled in advance on a flat ground near the site, lifted by a crane and dropped into a predetermined place. At this time, since the beam structure varies depending on the span, the columns must be surely arranged at predetermined positions. After completing the construction of the second floor floor beam and the first floor hut assembly, temporarily tighten the pillars, horizontal members, etc. with the blade bolts. Next, the pillars are erected, and bolts and fire beams are fully tightened. Reconstruction of pillars takes time as much as there are many to confirm one by one. After this, the work for assembling the hut beams on the second floor starts. In this case, a temporary scaffold is made on the second floor for safety measures. In this method, a joist is placed on the floor with an appropriate size, and a control panel to be used as a base plate is conveniently placed on the floor to create a temporary scaffold. However, the temporary scaffold may come off due to incomplete fixation or the like, and there is a problem that a fall accident or the like is likely to occur and lacks safety. In addition, when a formal scaffold is created instead of a temporary one, it takes time to load, load, install, and clean up components, requiring a lot of man-hours, lacking workability, and increasing costs. have. Next, the pillars and beams on the second floor are assembled. In this case, the pre-assembled ones may be lifted by a crane. However, when building a house on a narrow land in an urban area, the first floor is usually assembled in advance. However, on the second floor part, only the pillars are set up first, and then the beam girders are placed one by one in the determined places. Next, hut building materials such as a main building and a ridge are assembled. When the process proceeds to this scene, the remaining portion is reduced and a space is created. Therefore, the main building is set up to a spliced bundle, lifted by a crane, and stored in a predetermined position. After that, the roof timbers are delivered at a fixed pitch, but usually it is not enough to pay the roof timbers on the day of the upper building. It is normal until the end of the second floor floor beams in the morning and around 3:00 at the end of the hut. It is the process of the upper building day until the roof tall trees are raised up on the second floor with a relatively simple shape. Ideally, the ground floor will be hit on the day of the upper building with a large number of people, but it is often difficult with the structure of a conventional wooden house that is complicated and left to the carpenter. If at least the number of pillars is reduced, the floors on the second floor are simplified, the number of cross members is reduced, and the
The desired purpose cannot be achieved on the day of the upper building. After that, the tall tree is cut at the eaves of the eaves and the roof is closed and the roof is closed. Next, the asphalt roofing is completed by the person in charge of the tile work, and the work of roofing the tiles is started. During this time, the carpenter works to store studs and braces one by one according to the length of each place. As the principle of the horizontal material is that the top ends are all the same, the length of the pillar is different every time the beam is different, the bracing and stud length are different, and the bracing and stud are different for each installation location Adjust the length. Upon completion of the roofing work, the sash will be transferred to the exterior wall siding work. Currently, exterior siding is often left to the siding profession,
The carpenter starts the interior work after finishing the waterproofing sheet on the siding base. The first step in interior construction is usually called the precious wood decorative floor of the floor finishing material.
After the floor is insulated, the first floor will be constructed as it is on the second floor. In this case, since each room is partitioned by pillars that are erected in advance, the floor is pasted while the pillar portion is inserted in each room. After this, it is required to provide a curing sheet so as not to damage the floor. Fine sand is more difficult, so work with tape to prevent them from entering. or,
Gypsum board and thick veneer are placed on the curing sheet as a measure against falling objects from above. Normally, after finishing the floor, the construction is transferred to the wall and ceiling, so the curing of the floor is required first. After this, a ceiling foundation step, and in some cases, a wall foundation is performed, but generally, the ceiling is performed first. A plate having a cross section called a ceiling margin of about 9 mm × 36 mm and a length of 4 m or 3 m is installed at a pitch of 303 mm parallel or horizontal to the floor. At this time, a slope ceiling may be used according to the roof slope. After this, a gypsum board with a cross section of 9 mm or 12 mm is affixed on this edge. Next, the cloth base is applied. Electric wiring work is performed almost simultaneously at this time. The work for the ceiling base and the gypsum board for the ceiling base is performed for each section of each room similarly to the floor. When one carpenter works alone, it is common to perform the floor construction on the first floor, the floor construction on the second floor, the ceiling on the first floor, and the ceiling on the second floor. This is because a large amount of material scraps can be effectively used. However, when there are two or more carpenters, each carpenter concentrates on his or her own work, so the priority is given to the progress of the work rather than the effective use of the wood. Thereafter, the partition wall is constructed. This section also requires a wide variety of stud lengths to be cut while taking individual dimensions. After the stud construction, a 12 mm-thick gypsum board as a cloth base is pasted.
The Makabe construction method, in which pillars as structural materials used in a Japanese-style room other than the large-walled ones found mainly in the Western-style rooms as described above, are present in the same process, is substantially the same. Usually, a cloth or the like is attached and finished after finishing the wall base.

[0007]

However, the above-mentioned conventional method for constructing a wooden house has the following problems. (1) The conventional structure is constructed by building pillars on both sides of the opening, such as a door or a sliding door, and connecting the upper parts of these pillars with beams (floor beams or hut beams on the second floor). On the other hand, in the case of the second-floor floor beam (or the hut beam in the case of a one-story house) connecting the tip end surface of the pillar material, the height of the beam is determined by the span of the lower pillar or by how the load of the second-floor pillar is applied. . The beam structure of the commonly used floor beam is 105, 120, 150, 180, 210, 2
40, 270, 300, 330, 360 mm, width 10
Those having a size of 5 mm are generally distributed. Therefore, in the construction, there is a problem that a joint or a joint is required at each location where the beam structure is different, and a large amount of labor and man-hours are required for processing and joining. (2) In the pre-cut technology of the wooden house construction method, it is the inputting person who operates the CAD that performs the structural design based on the designed floor plan, and the standard wooden house is a reliable structural design standard like steel frame and RC structure. The floor plan was left to the carpenter's own discretion, because it did not need to be installed. The problem of design non-identity, which is a problem in the conventional method, is that the subject is only changed from a carpenter to a CAD input person.
As with the task of achieving fully automatic design using CAD, which is expected to be developed today, it remains unsolved. Specifically, various pillars used for wooden houses,
As mentioned above, building materials such as beams and girders require a large variety of products due to differences in dimensions and materials.
At the discretion of the AD input person, partial floor beams having partially different beam structures are connected in accordance with the floor plan of the lower floor. As described above, in the conventional wooden house construction method, there are many types of building materials to be handled, and the total number of building materials used is large, so that work is complicated at the time of construction, workability is lacking, and the structural design and estimation method of the house is, There was a problem that it could not be executed quickly and reliably unless someone who was familiar with it.

(3) In addition, although the types and quantities of building materials to be handled are extremely large as described above, since the amount of building materials of the same type is small, a large amount of space is required for storage and storage of the building materials. However, there has been a problem that inventory management is difficult. (4) The structure of the joints and joints is also complicated and the total number is large, and after the incision processing is performed, it takes a considerable amount of time and labor, even for a skilled carpenter, to properly perform it on site, In addition, the construction period is prolonged,
Further, there was a problem that much labor was required. (5) A foundation is always required directly below the pillar, and the pillar is erected at the opening, so the total number of pillars is large and the pillar structure becomes complicated, so this does not result in a complicated foundation structure that is difficult to construct As a result, for example, a total floor area of about 150 m ² 2
The total floor extension of the average foundation of a multi-storey wooden house with a floor area of 80 m ² or more was required to be about 80 m or more, and there was a problem that a large amount of material and construction time were required for the foundation work. (6) The gypsum board for the basement of the second floor wall and ceiling is large and heavy, so the lifting work is a human naval tactic of carrying a ladder on the upper floor and carrying it manually. Therefore, there is a problem that it is dangerous, lacks workability and is inefficient. (7) Since each room is partitioned by pillars, interior work must be done for each room and the work is complicated, and the length and width of the material are adjusted according to the size of each room and pressurized Therefore, there is a problem that a large amount of waste material is generated and workability and resource saving are lacking. Also, since all the room partitions are structural walls built between the pillars, many pillars are erected and fixed on the floor, so the size of the room to be partitioned and the width of the corridor, etc. After the construction, there was a problem that the design could not be freely changed and the partition lacked flexibility.

The present invention has been made to solve the above-mentioned conventional problems, and the type and quantity of various building materials can be reduced by standardizing column members such as corner columns and central columns, and horizontal members such as beams and girders. The structure design of a wooden house and its integration method can be carried out quickly and accurately without individual differences, even by non-experts. Since the types and quantities of building materials are small and uniform, mass production is possible even for wooden houses with different appearances, and inventory management and counting management of building materials can be easily performed. By reducing the total number of connection structures and joint structures, the mechanical strength of building materials can be improved, and the cutting of each building material can be performed easily and in a short time, shortening the construction period of wooden houses and building costs. Can be reduced. Partitions such as room size and corridor width can be changed freely during or after construction,
Design flexibility can be improved. Further, since the degree of freedom of the partition is extremely high, the design can be freely changed even after the construction according to various situations. It is possible to shorten the total length of rise of the foundation and realize a foundation structure that is easy to construct. In addition, it is possible to improve the workability of the corner pillar and the center pillar, and to improve safety. The workability and safety of the work of loading the plate material onto the joist can be improved. It is an object of the present invention to provide a novel wooden house construction method.

[0010]

In order to solve this problem, the present invention has the following arrangement. In the construction method for a wooden house according to claim 1, a plurality of corner pillars and a plurality of pillars each having a fitting groove formed with a predetermined depth and length on a front end surface and a side surface are erected on a foundation on an outer periphery of a building. A pillar erection step, a pillar erection step of erection of one or more large-section central pillars on a foundation inside the building, and fitting of the erected corner pillars, the pillars, and the central pillars A transverse step of bridging a transverse member having a large cross section between the grooves, a bundle erecting step of disposing and fixing the span member with a long span of 1.5 to 2.5 times the conventional length, and an erecting step in the bundle erecting step. A roof construction step of arranging a purlin, a purlin, etc. between the provided bundles, and a tall tree arranging step of arranging a tall tree between the main houses traversed in the roof construction step, ing. Here, the same horizontal members (height) are used as the horizontal members between the fitting grooves between the column members. This is for keeping the depth and length of the fitting groove constant. The beam structure may be changed between the first floor and the second floor. This is because the withstand load is different. In this case, 1
The length and depth of the fitting grooves for the floor and the second floor are made according to the beam structure. As a result, the length of each pillar is all the same, and the type of building material used can be significantly reduced,
As a result, even an inexperienced person can quickly and accurately perform the structural design of a wooden house and its estimation method without individual differences, and because the number of types of building materials is small, it facilitates management and estimation during building material purchase and storage. be able to. Furthermore, since the total number of the joint structure and the joint structure is small, the cutting process of each building material can be completed easily and in a short time, and the construction period of the wooden house can be shortened and the construction cost can be reduced. Since the erecting of the corner pillars is along the outer circumference of the building, there is an effect that the total rise of the foundation can be shortened and a foundation structure that can be easily constructed can be realized. In addition, since one or more central pillars having a large cross section are arranged at the center, the span between the pillar members can be widened, and the pillar members such as indoor pillars can be eliminated. In addition, since the beam structure of the outer peripheral portion and the floor beam can be made the same, the length of the column material can be made the same, and the foundation only has to be provided directly below the central column. It has the effect that the total length of the foundation can be significantly reduced at one or several places. Since the bundles are arranged in a 1.5 to 2.5 times longer span than the conventional one in the bundle erecting step, the number of work steps can be reduced and the resource can be saved. Since the number of pillars is small,
The foundation work is greatly simplified, the construction period can be shortened, and the space between the horizontal members can be widened, so that the interior materials can be hung down from above with a crane to significantly improve workability. It has the effect of being able to. Corner pillars and pipe pillars are placed around the outer periphery of the building, and independent central pillars are placed near the center of the building within the specified span, and the tips of these are placed with one or several types of limited horizontal members. Since the construction can be performed simply by joining, even an inexperienced person has an effect that the structure can be designed without any speedy difference. Since the number of types of wood is small, the number of joints and joints can be reduced, and the amount of wood to be used is significantly less than the conventional method. Having. Furthermore, since the type and amount of wood used are small, assembly at the site is easy, workability is excellent, and the work period can be significantly shortened. In addition, there is an effect that labor can be reduced and labor saving can be improved.

[0011] The construction method of the wooden house according to the second aspect,
In the invention described in claim 1, the horizontal members such as the girder and the beam have a structure made of two kinds of woods having the same or different beams. Thus, in addition to the operation described in claim 1, only one or two types of beams or beams of the horizontal members are required, so that the dimensions, arrangement, and how to hang the building materials such as columns and beams from the volume and strength of the wood. Has the effect of greatly facilitating structure determination.
Further, since the beam members of the horizontal members are the same, pipe pillars and studs of the same length can be used, so that the type of wood can be significantly reduced and the generation of waste materials can be significantly suppressed.

[0012] The construction method of a wooden house according to claim 3 is as follows.
The cross member such as the girder or the beam according to any one of Claims 1 and 2, further comprising a joist fitting portion on at least one side surface, and hanging the joist between the joist fitting portions after the transverse process. 2. A crossing member such as a girder or a beam formed on a side surface thereof, the method further comprising: a step of transferring a joist, and a step of laying a plate material on the bridged joist. Provided with a plurality of joist fitting portions. Thus, in addition to the operation described in any one of claims 1 and 2, by dropping the respective joists between the joist fitting portions of the respective horizontal members, the joists can be easily formed between the opposing horizontal members. It is possible to finish the floor surface, significantly improving the workability of ceilings and walls, and significantly improving the workability and safety of work on the floor, as it can be bridged over It has the effect that it can be done.

[0013]

m ² ), when the building was constructed in the first embodiment, the foundation arrangement required approximately 42 m (FIG. 2), whereas the conventional foundation arrangement required approximately 53 m (FIG. 7). From this, it was found that in this embodiment, the total base extension of about 20% or more can be reduced. In addition, it was obtained by simulation that the shortening rate of the total length of the foundation increased further as the floor area increased. Therefore, according to the present invention, it was found that remarkable shortening of the construction period and resource saving of materials can be realized. (5) Since there are few types of columns and horizontal members, the number of connections and joints can be reduced. The mechanical strength can be improved and the durability can be extended by the small amount of the joint structure and the joint structure. (6) Conventionally, the work space is narrow due to the large number of partition pillars and pipe pillars in the floor, and a large amount of labor is required for loading and construction of interior materials. Since there are only pillars and the span is long, the workability of interior work on each floor can be significantly improved, and the work efficiency can be reduced to about 1/10 of the conventional building with the same floor area. all right. (7) Conventionally, floors, ceilings, walls, etc. were constructed in each room, leaving extra material.However, this extra material wasted and wasted without any other use. However, in the present embodiment, the ceiling and floor are finished with a uniform material at one time, so that the amount of waste material is extremely small. Resource efficiency and labor saving can be significantly improved. (8) By using a panel wall provided with an entrance and the like as a partition wall, each partition can be extremely easily performed only by incorporating the panel wall between the pillars, and the labor can be reduced to about 1/5 as compared with the conventional method. I understand. (9) After the joist horizontal member process on the second floor, the slabs and the like are laid, so that the rigidity in the horizontal direction can be increased and the earthquake resistance can be improved. (10) Since the construction is performed one floor at a time, safety can be significantly improved, and since the assembling is performed in the order of the horizontal members, the joists, and the laying of the plate members, the workability and safety of the assembling work are improved. And the construction period can be significantly reduced. (11) Since the number of pillars is small, there is no structural wall, and the span is long, a wide open space can be provided at the top.Large and heavy building materials such as gypsum board at the time of the upper building can be craneed from above. Loading and unloading can be performed in one process, and the labor of transporting the product on stairs or ladders using a great deal of labor can be reduced.

As described above, according to the method for constructing a wooden house of the present invention, the following effects can be realized. According to the invention described in claim 1 of the present invention, (1) a corner post is erected on the outer peripheral portion, and a cross member is laid between the corner posts with or without a tube post; The center column is independently erected in the center, and the horizontal members such as floor beams are laid on the center column and the outer surrounding members (body, girder beams, etc.), making the structure extremely simple. There are three types of pillars: corner pillars, center pillars, and tubular pillars, and the same beam is used for the horizontal members.
As a whole, the type of pillar material was changed from 5 to 8
We were able to reduce to kind. (2) Since the number of pillars is small, the foundation work was greatly simplified and the construction period was shortened. Furthermore, since the space between the horizontal members can be widened, the interior material and the like can be hung by a crane and lowered from above, so that the workability can be significantly improved. (3) Arrange corner pillars and pipe columns around the outside of the building, place independent central pillars near the center of the building within a specified span, and place one or several types of limited lateral Since construction can be performed simply by connecting with a frame, even inexperienced people can surely design structures without speedy differences. (4) The number of connections and joints can be reduced by the small number of types of wood, and the amount of wood to be used is significantly smaller than that of the conventional method. I can do it. Furthermore, since the type and amount of wood used are small, assembly on site is easy, workability is excellent, and the construction period can be significantly shortened. Further, labor can be reduced, and labor saving can be improved. (5) Since each floor is assembled in the order of erected pillars, horizontal piers, hangers, and laying of board materials, etc., a scaffold is reliably obtained, and workability of assembling work on the upper floor is remarkably improved. In addition, since the scaffold is flat, safety can be significantly improved and the construction period can be significantly reduced. (6) A plate material such as a discarded floor on the second floor can increase the rigidity in the horizontal direction and significantly improve the earthquake resistance. Also, 2
The floor is laid on the floor, the number of pillars is small, and the span between pillars is large, so it can be lowered to the floor from above with a crane at the time of the upper building, allowing the gypsum board to be loaded and significantly saving labor. . (7) The total length of rise of the foundation can be significantly reduced. Since the pillars are erected only in the central part and the peripheral part, the total length of the foundation is 106 m because there is no need to arrange a complicated foundation as in the past.
^In the case of the ^second house, about 53 m was required, whereas in the present invention, it was reduced to about 42 m, which is a reduction of about 20%. According to the second aspect of the present invention, in addition to the effect of the first aspect, (8) Since all the beam structures are unified and the number of types is extremely small, it is possible to surely design quickly even inexperienced. Can be done. (9) Automated design is difficult because there are few types of horizontal members such as columns, beams, and girders, which are difficult to automatically design with the conventional automatic beam design system (CAD). Could be made possible. (10) The number of joints can be reduced by about 15% to 35% as compared with the conventional one, and since the back of the cross member is constant, intensive stress is not generated and mechanical strength is remarkably improved, and seismic resistance is improved. Performance can be improved. (11) Since all partitions are non-structural walls, partition walls can be constructed in each room after the ceiling has been constructed first,
The work can be streamlined, and the shortening of the construction period can be significantly improved. In addition, since it is a non-structural wall, it can be removed later, and the partition can be freely changed according to the increase or decrease of the family. Further, it is possible to realize a barrier-free wooden house in which the width of the corridor can be freely set. Conventionally, pillars were erected in advance for each room, but in the present invention, partitions are made later, so that the room size can be freely set.
According to the invention described in claim 3 of the present invention, in addition to the effects of claim 1 or 2, the workability of ceilings and walls is significantly improved, and the workability and safety of work on floors are significantly improved. Can be
