Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a precast panel for imparting a high-wall magnification strength capable of easily constructing an important high-strength wall in a wooden building.

[0002]

2. Description of the Related Art Wooden buildings can provide high strength against rolling in the event of an earthquake or the like by providing a bracing in a wall space between adjacent columns. In recent years, it is desired to construct a high-bearing wall with excellent seismic resistance by providing this bracing, and in many cases, this configuration is actually adopted. A bracing structure for this purpose is a rectangular wall space formed by two adjacent vertical columns, a lower base, and an upper spar (horizontal member). A method of providing a brace along one diagonal, a method of providing a brace in an X-shape along two diagonals, and a cross-shaped brace to further improve strength A method of connecting and fixing the struts together with nails or the like is adopted as necessary, and conventionally, these braces are usually constructed by on-site work.

[0003] As described above, it is recommended to provide a bracing structure to form a bearing wall having a high wall ratio in order to improve earthquake resistance. The problem is that the number of work steps increases, the construction work period becomes longer, and the construction cost increases.

[0004] Therefore, in order to solve the above-mentioned problems, and in particular, to reduce the number of work steps and shorten the construction work period, a precast type panel (hereinafter referred to as a "wall proof panel") for providing a proof strength of a high wall magnification. ) Has been proposed and used in practice. As a conventional example of such a wall strength imparting panel, a precast type panel in which an X-shaped bracing is preliminarily incorporated along a diagonal line inside a rectangular (rectangular) frame material is conventionally known. . This rectangular frame type precast panel is used after being manufactured at a wood processing factory, and then transported to a building construction site by a truck or the like and fitted into a predetermined wall space.

[0005] However, such a rectangular frame structure precast type wall strength imparting panel has the following problems. In other words, in wooden buildings, there are basically no major changes because the adjacent pillars are designed and constructed to have a fixed spacing specified by the Building Standards Law, but the base and girder etc. are at the request of the owner. There is a tendency to be designed with various specifications. For this reason, especially the vertical (vertical) dimensions of the wall space into which the panels are fitted often differ from building to building, and a combination of generally known flooring materials, girder materials, etc. However, there are about 80 types of differences in size, and thus panels for these different sizes are required. Therefore, the above-mentioned rectangular frame-type wall strength imparting panel is a kind of custom-made type manufactured according to the design dimensions of each building, and is not suitable for mass-producing the same general-purpose product. There are structural disadvantages. As a result, in the case of using such a rectangular frame structure precast type wall strength imparting panel, although the advantage of using a precast type panel that can shorten the period of on-site work can be obtained for the time being, it is not easy to reduce the panel manufacturing cost. In addition, the production of many types of panels, which require an average of about 50 per building, requires large storage facilities, which is not appropriate. There is a problem that there are many inconveniences.

In addition to the above problems, there is another problem that the panel having the rectangular frame structure is not easily changed in external dimensions. That is, even if the panel is accurately dimensioned, it is often unavoidable that the wall space of the building under construction slightly deviates from the actual dimension. However, since the panel cannot be fitted into the wall space even with a slight deviation, it is necessary to adjust the external dimensions formed by the rectangular frame material. But,
Since this rework is a work to correct the external dimensions of the rectangular frame structure, it is inevitable that considerable time will be taken, and this will shorten the construction period, which is the advantage of using precast panels. Undesirable results are not obtained.

Therefore, the problem in the conventional precast type panel having such a rectangular frame structure, particularly the problem when there is a slight deviation between the design dimensions of the wall space of the building and the production dimensions of the panel can be solved with a simple operation. It is conceivable to do so. As such an example, for example, a precast type panel is not proposed.
No. 4253, Japanese Unexamined Patent Publication No. 8-270101, etc., specifically, as shown in FIG. 8A, two bracing members 300 and 301 are crossed in an X-shape. The crossing portion 303 is connected and fixed with a nail 304 or the like, or as shown in FIG.
Plywood 305 and the like are laminated to form a precast panel, and the ends of these bracing members 300 and 301 are connected to the base 306 and the girders 307 by the fasteners 308 and 309. Can be

By using a panel having such a structure,
As can be seen from FIG. 8, slight deviations in the vertical dimension of the wall space and panel bracing can be absorbed by the ties, and in some cases, the ends of the two intersecting braces are cut off. Therefore, it is possible to perform the fitting operation easily and in a short time because the dimension can be adjusted relatively easily.

[0009]

However, according to further studies by the present inventor, a panel having the structure shown in FIG. 8 which is basically made of only two bracing members has the following features. There are still some issues to be improved.

The first problem is that the effect of improving the magnification of the wall proof strength is insufficient, and the second problem is that it is required to further improve the work of fitting the panel into the wall space.

For the former improvement in the magnification of the wall proof stress, for example, the following problem arises. In other words, two bracing members that are effective in improving the wall proof strength are formed in an X-shape.
Even when the bracing material used is thin, the wall magnification determined by the Building Standards Law is low (30 mm
This is higher when a thicker material is used (three times with a 90 mm material) (four times with a 45 mm x 90 mm material).
Therefore, it is desired that a material as thick as possible can be used in order to enable a high wall magnification. However, in the structure shown in FIG. 8 in which two bracing members are crossed, it is difficult to use a thick material due to the thickness of the wall space, so that there is a problem that the wall strength cannot be increased in magnification.

On the other hand, the following simplification of the latter panel fitting operation involves, for example, the following problems. In other words, the wall space is used not only for providing bracing, but also as a space for mounting and filling insulation materials and drawn-out hardware (hole-down hardware). Simplification is required. However, in the structure of the brace panel made of the two crossed brace materials described above, since the brace material is shifted in the thickness direction, for example, when used as a filling space for a heat insulating material, Since the heat insulating material cannot be filled in a uniform plane, further measures are required, and the assembling positions of the drawn metal parts differ in the left and right directions in the thickness direction, so that it is inevitable that the work becomes troublesome.

The present invention has been made in consideration of the above-described various viewpoints.
An object of the present invention is to provide a new precast-type wall bearing panel capable of constructing a bearing wall having a high wall magnification by an easy operation.

Another object of the present invention is to significantly improve construction performance in that a load-bearing wall can be constructed by an easy operation.
It is an object of the present invention to provide a wall bearing panel capable of shortening a construction period.

[0015]

The above-mentioned object is achieved by the invention of a high-magnification wall-strength imparting panel described in the claims of the present application.

According to a first aspect of the present invention, there is provided a wall-strength imparting panel having a high wall magnification, comprising: a first elongated bracing member arranged along one of two diagonal lines connecting four vertex positions of a vertically long rectangle; A second and a third bracing member extending from the apex position along the other of the two diagonal lines and arranged so as to hit the first bracing member near the intersection of the two diagonal lines.

In these figures, a precast-type wall-strength imparting panel 1 formed in advance in the structure shown in FIG. 1 includes, for example, two columns 201, 201, a base 202, and an eaves girder 203 of a wooden building 2 in FIG. As shown in FIG. 3, it is used so as to be fitted into the enclosed wall space 200 (thickness D) to improve the wall resistance.

The wall proof panel 1 of this embodiment has a long bracing member 101 which is installed obliquely along one diagonal line of the wall space 200 and another diagonal line crossing the diagonal line. It has short brace members 102 and 103 which form an X-shaped brace structure together with the long brace member 101 by being installed diagonally, and each of these X-shaped brace members has an X-shape. As shown in FIGS. 1 and 3, the end portion has a horizontal surface 1012, 1022, 1032 and a vertical surface 1011.
1021 and 1031 are machined into orthogonal shapes,
The vertical surfaces 1011, 1021 and 1031 correspond to the wall space 20.
0, and the horizontal surfaces 1012, 1022, and 1032 are on the inner surface 2011 of the pillar 201 forming the base 2.
02 or the inner side surfaces 2021 and 2031 of the eaves girder 203. The other end of each of the short brace members 102 and 103 is a long brace member 1.
The contact surfaces 1023 and 1033 are cut off obliquely so as to contact the surface 01.

Reference numeral 110 denotes the three bracing members 101, 1
A joint made of a thin metal plate for connecting and fixing 02 and 103 as an X-shaped bracing structure. In this example, the joint is formed by processing a galvanized iron plate. The detailed structure is shown in FIGS. 4 and 5, and is slightly wider than the width L of the brace (for example, 130 m when the brace is 45 mm × 90 mm).
The iron plate, which is a thin plate having a rectangular shape with a width of m, is cut at positions about 1/3 from both ends of the long sides on both sides with the center being a point symmetrical point (the cut depth in the above example). (For example, 20 mm), and the short piece is bent at a right angle to form a bent flange 112. Thereby, the full width L of the short bracing members 102 and 103 and the long bracing member 10
1 and a plate main body 111 in close contact with the side surface (the surface side in FIG. 1A), and surfaces 1024, 1034 in the thickness direction of the short bracing members 102, 103 bent at a right angle from the main body 111. Folded flange portion 112 that is in close contact with
Then, a joint 110 made of a thin metal plate is formed, which includes an extension flange portion 113 extending without being bent from the main body portion 111. The joint 110 is connected to the plate body 111 and the bent flange 112 with the bracing members 101 to 103.
Nail hole 11 for fixing by nailing (not shown)
4 are provided at appropriate intervals. Since the bent flange portion 112 is mainly for increasing the strength of the joint 110, fixing this portion to the bracing member by driving nails may be omitted.

In the case where a zinc-plated iron plate is used as a joint for connecting and fixing the X-shaped bracing structure having the above-described exemplary dimensions, the material of the joint is 9 mm in thickness.
Thickness is appropriate.

Returning to FIG. 1, the wall strength imparting panel 1 constructed according to the present embodiment will be further described. Reinforcement plates 121 and 122 formed in a rectangular shape using structural plywood have long dimensions. The (lateral dimension) is equal to the interval between the columns 201 and 201 of the wall space 200 (actually, it is slightly shorter in order to make the fitting smooth: for example, the interval between the columns is 7).
When it is 90 mm, the horizontal dimension of the panel is 789 m
m) in the position excluding the vicinity of the end of the X-shaped braced structure and the vicinity of the intersection (fixed portion of the joint 110).
As shown in (b), it is fixed to the bracing members 101, 102 or 101, 103 by nailing (black dots in the figure indicate nailing points: the same applies hereinafter). In this example, the reinforcing plates 121 and 122 are fixed to the same surface (the indoor surface of the building) of the X-shaped bracing on the same side as the surface to which the joint 110 is fixed.

Reference numerals 131 and 132 denote square bars fixed by nailing between the lateral ends of the upper and lower reinforcing plates 121 and 122 fixed to the X-shaped struts as described above. It is a standing frame made of a material, and in this example, the reinforcing plate 12
For example, nails are fixed on the same surface as the fixing surfaces of the 1,122 bracing members, and the thickness thereof is
The same as 103 (for example, 45 mm square in this example) is used. By providing the upright frames 131 and 132 as described above, when the panel 1 is fitted into the wall space 200, the upright frames substantially come into contact with the inner side surfaces of the columns 201. By temporarily fixing the standing frames 131 and 132 to the columns 201 by nailing, the posture of the panel is stabilized in the wall space, and in this state, the ends of the bracing members are connected to the columns 201, the base 202, and the eaves girders 203.
The work of connecting and fixing the fixed parts with predetermined fixing fittings (not shown) can be easily performed.

Since the vertical frames 131 and 132 connect both ends of the upper and lower reinforcing plates 121 and 122, respectively, there is an advantage that the vertical frames 131 and 132 also function as a twist stopper for the reinforcing plates 121 and 122. Can be

Reference numerals 141 and 142 denote center rails which are made of square bars and are used for fixing an outer wall material (not shown). In this embodiment, at the intermediate position in the lateral direction of the X-shaped bracing, the wall space is formed. It extends from the upper and lower ends to the intersection of the X-shaped brace structures, and is fixed to the reinforcing plates 121 and 122 by nailing on the same surface as the fixing surface of the brace material. In this example, the bracing members 101 to 103 are used.
(For example, 45 mm square in this example) is used, and the ends of the middle bars 141 and 142 on the intersection side are configured to be in contact with the inside of the extension flange 113 of the joint 110. Accordingly, it is possible to prevent runout when the outer wall material is fixed to the middle crosspieces 141 and 142 by nailing, and nailing can be performed effectively.

Reference numeral 150 denotes a stud, which is made of a square bar and is provided at the same position as the middle crosspieces 141, 142 at the same position.
1,122 is fixed by nailing to the surface opposite to the fixing surface of the middle crosspiece. The studs 150 are used to fix interior wall materials (not shown), and
3 plus the thickness of the reinforcing plates 121 and 122;
One having a predetermined thickness determined by the relationship with the thickness dimension of the wall space is used.

The studs 150 may be fixed at the time of precasting the wall bearing panel, or may be fixed at the site. FIG. 1 shows a state in which the precast panel does not include the studs. I have.

The wall strength imparting panel 1 having the above-described structure is
It is manufactured in a wood processing factory or the like, and transported to a construction site by a truck or the like for use. In addition, the panel 1 of this example is mainly composed of a reinforcing member and a reinforcing plate, and each of the reinforcing members is provided on a single plane, so that the rectangular frame member surrounds the X-shaped reinforcing member. Compared to this, the advantages are that the weight is significantly reduced, the handling property and the lamination are easy, and the load (operability and cost) required for transportation is reduced.

Next, the work of fitting the above panel 1 into the wall space will be described. The panel 1 conveyed to the building site as described above is provided in the predetermined wall space shown in FIGS. It is made to fit in. At this time, pillar 2
Since the interval between 01 and 201 is set to a predetermined size, it is not generally necessary to adjust the size. On the other hand, the dimension in the vertical direction (vertical direction in the case of the panel) may vary depending on the thickness of the base or eave girder used at the site as described above, but in the panel 1 of this example, the X-shaped stripe is used. The vertical dimension can be easily modified by shaving or cutting off the end of the bracing material forming the bracing structure along the horizontal plane, and thus can be mass-produced as a highly versatile panel. . It should be noted that the dimensions may be modified and then transported after being carried out in a factory. In this case, the production can be mass-produced in accordance with the same production standard dimensions.

The panel 1, whose dimensions have been appropriately adjusted as required, is fitted into a predetermined wall space, and the standing frames 131, 132
Is temporarily fixed to the pillar 201 in a predetermined posture in contact with the pillar. This temporary fixing can be generally performed by nailing.

With respect to the panel 1 whose posture has been stabilized in the wall space by the temporary fixing, a drawn-out hardware (hole-down hardware) is used.
The work of constructing the bearing wall is performed by firmly fixing to a predetermined object such as the base 202, the eaves girder 203, and the column 201 by using a fixing hardware such as.

The construction of the bearing wall using the wall bearing panel of the present embodiment is completed by the above operation, and is extremely easy and in a short time (one-half as compared with the case where the X-shaped bracing structure is assembled on site). (Shortened to about 4), and by performing the temporary fixing using the standing frames 131 and 132, there is obtained an advantage that the assembling work of the pulled-out hardware can be easily and easily performed. Further, in the configuration of this example, since the reinforcing plate is divided into upper and lower parts and the middle part is open, the standing frames 131 and 13 are provided.
There is an advantage that the temporary fixing operation 2 can be easily performed.

Further, according to the panel having the structure of this embodiment,
Even if a 45 mm x 90 mm square timber is used as a bracing material for a 120 mm thick wall space and a 9 mm thick structural plywood is used as a reinforcing plate, a sufficient space for filling the inside with a heat insulating material or the like. In addition, since it is possible to secure a uniform planar space and to provide a sufficient mounting margin for the fixing hardware such as the above-mentioned drawing hardware, the construction materials used and the structure of the X-shaped braces make it difficult to comply with the Building Standard Law. There is an unprecedented advantage that a high-magnification bearing wall having a wall magnification of 4 can be constructed.

Embodiment 2 The wall strength imparting panel 160 of the present embodiment shown in FIG. 6 is different from the structure of Embodiment 1 in the following points.

That is, the present embodiment is different from the first embodiment in that the joint 110 is omitted, and two reinforcing plates 121 and 122 provided in the first embodiment are vertically separated from each other. In this case, one piece of structural plywood that is continuous and long in the vertical direction (vertical direction) is used as the reinforcing plate 161, and the surface of the long brace 101 and the short brace 1
02 and 103 are fixed by nailing, and
1, 132 and the members 141, 142 are fixed by nailing so as to have the same arrangement as in the first embodiment. Further, the stud 150 is fixed by nailing on the rear surface in the same arrangement. It shows a precast type panel as a wall strength imparting panel.

According to the configuration of this example, substantially the same effects as in the first embodiment can be obtained. That is, the wall strength imparting panel 160 of this example is exactly the same as the first embodiment in that it is manufactured in a wood processing factory or the like, and is used by being transported to a building site by a truck or the like, and is a panel having a conventional rectangular frame. The burden (operability, cost) required for transportation and the like as compared with the structure is greatly reduced.

Also, the vertical dimension can be easily modified by shaving or cutting off the end of the bracing material along the horizontal plane as in the first embodiment described above. However, since a panel having a size similar to this can be easily modified and used, it can be mass-produced as a highly versatile panel.

Further, the panel 160 is fitted into a predetermined wall space, and the standing frames 131, 132 are temporarily fixed to the columns 201, 201 in a predetermined posture in contact with the columns 201, and in this state, a pull-out metal (hole down) is mounted. Using fixed hardware such as hardware)
The work of firmly fixing to the predetermined object such as the base 202, the eaves girder 203, the column 201, and the like, and constructing the bearing wall can be performed easily and in a short time. In addition, by performing the temporary fixing using the vertical frames 131 and 132, the assembling work of the pulled-out hardware can be easily and easily performed.

Further, there is an unprecedented advantage that it is possible to secure a sufficiently uniform space in a wall space filled with a heat insulating material or the like while securing a high wall magnification (for example, 4 times). Third Embodiment A wall strength imparting panel 170 of this example shown in FIG. 7 is a panel having a configuration in which the interval between the columns 201 is set to be wider (longer), for example, 1260 mm, as compared with the configuration of the first embodiment. The basic configuration is the same as that of the first embodiment. That is, the lateral dimension of the panel is, for example, 1259 mm, which is 1 mm shorter than the interval between the columns, and with the increase in the lateral interval, the middle rails 141 (upper side) and 142 (lower side) are each positioned at two positions in the lateral direction. In addition, the outer wall material can be securely fixed by juxtaposing the studs 150, and the studs 150 are similarly juxtaposed at two positions in the lateral direction so as to securely fix the interior material. Is different,
Other than that, the types and the numbers of the constituent members are the same. Therefore, the same members (including those having different dimensions) are denoted by the same reference numerals, and description thereof will be omitted.

According to the configuration of this example, the same effect as that of the first embodiment can be obtained. That is, the panel 1 of the present embodiment has a wall strength.
70 is manufactured in a wood processing factory or the like and transported to a building site by trucks or the like for use. In this example, the panel 170 having a longer width dimension has a larger weight per panel than in the first embodiment. Although it is bulky, since the reinforcing plate is divided into upper and lower parts and its area is limited, the effect of reducing the load (operability and cost) required for transportation as compared with a panel structure having a rectangular frame is further improved. It will be big.

Also, the vertical dimension can be easily reworked by shaving or cutting off the end of the bracing material along the horizontal plane as in the first embodiment described above. However, since a panel having a size similar to this can be easily modified and used, it can be mass-produced as a highly versatile panel.

Further, the panel 170 is fitted into a predetermined wall space, and the standing frames 131, 132 are temporarily fixed to the columns 201, 201 in a predetermined posture in contact with the columns 201, and in this state, a pull-out metal (hole down) is mounted. Using fixed hardware such as hardware)
As in the first embodiment, the work of constructing a bearing wall by firmly fixing to a predetermined object such as the base 202, the eaves girder 203, and the pillar 201 can be performed. Further, since the panel 170 is lighter in weight than the conventional panel, the advantage that the operator can perform the work at this time by himself is also exhibited. For this reason, the construction of the load-bearing wall can be performed extremely easily and in a short time, and the temporary fixing using the standing frames 131 and 132 allows the assembling work of the pull-out hardware to be easily and easily performed. The advantage that the temporary fixing work of the standing frames 131 and 132 itself is easy because the reinforcing plate is divided into upper and lower parts and the middle part is opened is also provided.

In addition, the same advantage that has not been obtained in the past can be obtained that a sufficiently uniform flat space for filling a heat insulating material or the like in the wall space can be sufficiently secured while securing a high wall magnification (for example, 4 times).

[0060]

As described above, the following effects are achieved by the invention proposed in the present application.

That is, according to the first and third aspects of the present invention, it is possible to construct a bearing wall having a high wall magnification of 4 times, which is difficult with the conventional precast type panel, and furthermore, a bearing wall having the high wall magnification. Can provide a new wall strength imparting panel that can perform the construction work easily and in a short time, improving the construction efficiency, significantly shortening the construction period,
In addition to excellent effects such as cost reduction, the following effects are further obtained.

The brace structure constructed by the conventional conventional construction method is such that the brace material forming the X-shape crosses at a position displaced in the thickness direction (overlapping position) and is located within the same plane. Because it is a structure that is not provided, even if it is possible to achieve the same reinforcing effect in terms of strength by integration with a joint or a backing plywood, a reinforcing structure that is applied in a wall space that is restricted in thickness direction dimensions As a material, inconvenience is caused in securing the heat insulating material filling space and securing the assembling volume of the drawn metal parts. On the other hand, the wall strength imparting panel of the present invention has a feature that the bracing members forming the X-shaped bracing of the framework as the basis of the wall strength are located on the same plane, and the thickness direction in the wall space. Therefore, it is easy to secure a space for filling the heat insulating material and assembling the drawn metal parts.

By using the wall strength imparting panel of the present invention, the temporary fixing can be performed using the standing frame, so that the temporary bracing used at the time of construction can be greatly reduced.

A: It is possible to realize a bearing wall magnification of 4 according to the Building Standards Law, and it is extremely useful for popularizing highly durable houses with high earthquake resistance.

With a simple operation such as cutting the end of the bracing material, it is possible to easily cope with a slight change or deviation in the dimensions of the wall space.

The brace material forming the X-shaped brace is located in a single plane, so that loading can be carried out well from this surface and also during transportation, and since it is lightweight, it can be constructed from a factory. It can be easily transported to the site, and can be operated by one person alone, which is effective in reducing costs.

Since the X-shaped bracing having a small thickness dimension is used as the basic structure, a high-strength true wall can be realized by making the pillars of the true wall structure thin and high-strength walls. In addition, housing a high heat insulating material can realize a high heat insulating house.

A panel that gives strength is manufactured accurately and with high precision in a factory. At the site, it is only necessary to fit the panel into a predetermined wall space and fix it with a predetermined connection hardware. It is possible to make a high-accuracy, high-strength house without using it.

Further, according to the second aspect of the present invention, the number of work on site can be further reduced by integrating the middle crosspiece used for fixing the outer wall material to the panel in advance, and the middle crosspiece can be connected with the joint. Since the anti-sway is used, the middle crosspiece is stable even when the outer wall material is fixed.

According to the fourth aspect of the present invention, the number of operations on site can be further reduced by previously integrating the stud used for fixing the interior material to the panel.
