Abstract

PURPOSE:To save house construction cost by forming units as integral sections of upper and lower floors, setting up the units or the units and columns at intervals, and extending floor and wall panels between the aforesaid units or between the units and columns. CONSTITUTION:For the manufacture of the frame 1a of a two-floor unit 1 for upper and lower floors at the factory, a column 2 and beam 3 made of assemblies are used as square members. Also, four columns 2 are positioned in parallel at the corners of the frame 1a, thereby forming a vertically long box body. Then, the frame 1a is set up with a free working posture and panels including a floor, a wall and a coiling are laid at such positions as not obstructing a work with the units 1. Thereafter, four completed units 1 are transported to a construction site, and placed on foundations 4 preliminarily constructed as the four corner sections of a unit house. Then, floor panels 5a are extended between the units 1 at lower and intermediate level, thereby forming the floors 5 of the first and second stories. According to the aforesaid construction, labor for a work at the construction site can be saved.

Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention provides an R
The present invention relates to a method of constructing a two-unit house, and particularly relates to a method of constructing a two-story unit house using a unit in which the upper and lower floors are formed into one unit.

[Prior Art] In recent years, modular housing has become popular in order to shorten construction periods and save labor on site.

This unit housing consists of a collection of living room units, and is constructed by assembling various box-shaped living room units that have been standardized and manufactured in advance on a foundation during on-site construction.

Conventionally, this unit house has been constructed such that the majority of the house is made up of the above-mentioned room units.

At the junction of the first-floor unit and the second-floor unit in this unit house, there is a groove above the ceiling of the first-floor unit that forms a box, and below the floor of the second-floor unit. Shaped steel is arranged to form a frame structure, and the grooved steel is connected to each other by bolting.

In addition, equipment that requires piping, such as a bathtub, has been installed in the unit in advance at the factory.

[Problems to be Solved by the Invention] Incidentally, the unit is inevitably subject to size limitations because it is transported from the factory by truck or the like. Therefore, the floor plans of unit houses, where living rooms are made up of units, were also restricted.

In addition, since the unit has sufficient strength even when it is only a unit before being assembled as a house,
If adjacent units of a unit house are subjected to stress, the stress will be distributed and each unit will receive the stress, and the unit house as a whole will have more strength than necessary, and the building material There was an aspect that it was uneconomical in terms of usage amount.

Another drawback is that it takes time and effort to join the units on the first floor and the units on the second floor on site.

When installing plumbing in unit housing, it is either the piping of the unit itself or it is already done at a factory.
At the site, work was carried out to connect the piping between the units, particularly the work to connect the piping on the second floor to the piping on the first floor, but this work was also time-consuming.

Therefore, the joining work of these units and the work of connecting piping have been an obstacle to promoting labor saving in on-site work.

This invention was made in view of the above circumstances, and -
By eliminating the need to connect the floor needle unit and the second floor unit, and the connection between the floor needle piping and the second floor piping, it saves on-site work, reduces constraints on the floor plan of unit housing, and saves building materials. The purpose is to provide a method of constructing a two-story unit house with upper and lower floors that can reduce the number of units.

[Means for Solving the Problems] The construction method of the upper and lower two-story unit housing of the present invention includes manufacturing a unit consisting of a floor, walls, ceiling, etc. in advance in a factory, etc.
A construction method for a unit house in which the housing is assembled using the units at a construction site, the upper and lower two floors being integrated to form the unit, and the units or the unit and the pillars being spaced apart from each other at the construction site. The feature is that a house is constructed by installing floor panels between these units or between the units and pillars, and installing wall panels.

[Operations] According to the above configuration, since the upper and lower floors are integrated to form a unit, it is possible to construct a unit house without joining the first floor unit and the second floor unit at the construction site.

Piping that spans the upper and lower floors can also be done at the factory.

In addition, the majority of unit housing is not constructed by units, but by arranging units with intervals between each other or between units and pillars, and constructing the housing by spanning floor panels between them. Since the parts are not subject to floor plan restrictions, you can freely decide on the floor plan.

[Example] Embodiments of the present invention will be described below with reference to the drawings.

In the method of constructing the upper and lower two-story unit house of the first embodiment, first, a frame 1a of the upper and lower two-story unit 1 shown in FIG. 1 is manufactured in a factory. When manufacturing this frame la, the pillars 2 and beams 3 are made of glulam, which are made by stacking small square timbers with their fibers aligned longitudinally and pasting them together with an adhesive to form square timbers. Then, four pillars 2 are arranged in parallel at the corner positions of the frame 1a, and four pillars 2 are placed at the upper end, lower end, and center of the four pillars 2, respectively.
The four pillars 2 are assembled into a rectangular frame shape using book holders 3 to form a substantially box-like shape elongated in the vertical direction.

Note that this pillar 2 and 3 are not made of laminated wood, but are made of steel frame.
I don't need to say that I don't mind if it's beam 3.

In addition, the size of the unit 1-] is limited by transportation from the factory to the site, so it must be large enough that the entire unit 1 can fit in the bed of a truck when loaded horizontally, and that it can be driven on the road. It is set at a height that does not cause any hindrance.

Next, equipment such as a bathtub is attached to the framework Ia. At this time, since the framework la has a vertically long structure, the framework la is laid down and the equipment installation work is performed in a stable state. Therefore, there is no need to crawl under the floor to perform piping work on the parts that are under the floor of the - floor or the second floor, and the piping work can be performed in a comfortable posture.

In addition, piping that spans the negative and second floors can be easily performed during piping work at the factory.

Next, panelized floors, walls, ceilings, etc. will be installed in areas that will not interfere with the construction work at Units) 1's site.

Then, the four completed units l are transported by truck to the construction site.

As shown in FIG. 2, four Uni-Soto l are installed at the four corners of a house on a pre-constructed foundation 4 at a construction site.

As shown in Figure 3, these four uni-soto l
The floors 5 of the first and second floors are formed by installing a floor panel 5a spanning between the lower and central parts of the floor.

Note that at this time, a beam may be spanned between the units 1 and then the floor 5 may be formed thereon.

Next, the exterior is completed by installing wall panels and roof panels. Then, interior decoration is carried out to complete the upper and lower two-story unit housing (not shown).

At this time, the layout of the parts other than the unit 1 can be freely determined because the unit size is not restricted by transportation using a truck.

According to the construction method of the upper and lower two-story unit house of this first embodiment, since the unit l is integrated into the upper and lower two floors, there is no need to connect the first floor unit l and the second floor unit l on site. It disappears.

Furthermore, work such as piping work that spans two floors above and below can be done at the factory.

Therefore, it is not necessary to perform the work of joining the upper and lower units 1 and the work of connecting the upper and lower piping on the site, so that the work at the construction site of the unit house can be labor-saving.

In addition, for the vertically long two-story unit l, it is better to lay it down on its side when installing equipment, so that the unit and soto 1 can work in a stable state, so you can work on piping under the floor, etc. You can perform work under the floor in a comfortable position, increasing work efficiency.

In addition, the majority of the house is not made up of units L, but rather the units L are placed at the four corners, so unlike conventional unit houses, units L are used in adjacent areas such as pillars 2, beams 3, walls, etc. Since there is no need for double construction, construction materials can be reduced. Therefore, the cost of unit housing can be reduced.

Furthermore, since a unit house is constructed by arranging the unit l at the four corners and spanning the floor panels 5a between them, the floor l other than unit 1 (for the part where the flannel 5a is stretched, the living room is Since there are no restrictions on transportation, you can freely decide on the floor plan.

The construction method for the upper and lower two-story unit house of the second embodiment shown in FIG.
A house is constructed by placing pillars 10 on I, spanning floor panels 5a between these units 1 and pillars 10, and installing wall panels. Description of the constituent elements will be omitted.

The construction method of the upper and lower two-story unit house of this second embodiment is that, in contrast to the first embodiment in which the floor panels 5a are spanned between the units 1, a floor panel 5a is spanned between the units 1 and the pillars 10. The structure is similar to that of the previous one except that 5a is crossed over.

In addition, when spanning the floor panel 5a, the pillar lO and the pillar 106
Alternatively, a beam may be spanned between the pillar 10 and the unit l-1, and then the floor 5 may be formed in the shape of a second beam.

The construction method of the upper and lower two-story unit house of the second embodiment has the same effects as the first embodiment, and since only one unit L is used, there are fewer restrictions on the floor plan. , you can decide the floor plan more freely.

Note that when manufacturing the unit I, the unit 1 may be manufactured by directly combining wall panels, floor panels, ceiling panels, etc., without creating a framework using laminated wood or steel frames. In addition to arranging unit 1 at the four corners, or arranging unit 1 at the center and pillars 10 at the four corners, it is also possible to arrange multiple units 1 or multiple units 1 and pillars 10.
Needless to say, it is possible to construct a unit house by installing the floor panels 5a and extending the floor panels 5a between them.

Although there are almost no restrictions on the floor plan for the unit house as a whole, the units themselves are transported to the construction site by truck, so they are still subject to size restrictions. However, the unit 1 is used as a part of the house, and it is a suitable space for installing various facilities such as stairs, an elevator-1 bathroom, and a toilet.

[Effects of the Invention] As described above in detail, according to the upper and lower two-story unit housing of the present invention, by integrating the upper and lower two-story units, it is possible to separate the first-floor unit and the second-floor unit at the construction site. There is no need to join.

Furthermore, work such as piping work that is carried out consecutively on two floors above and below can also be carried out at the factory.

Therefore, work to join the upper and lower units, connect work to connect the upper and lower pipes, and the like does not need to be performed on site, so that labor at the construction site of the unit house can be saved.

In addition, for a two-story unit that is long in the vertical direction, it is better to lay it down on its side when installing equipment, so that work can be done with the unit in a stable state. Work that is performed under the floor, such as plumbing work, can be done in a comfortable position, increasing work efficiency.

In addition, by installing the units or the units and pillars at a construction site at intervals, spanning the floor panels between the units or between the units and the pillars, and installing wall panels to construct a house, Since there are no double columns, beams, walls, etc. in the adjacent parts of the units, unlike when most of the house is constructed from units, construction materials can be reduced.

Therefore, the cost of unit housing can be reduced.

Furthermore, because we construct unit housing by spanning the floor panels between units or between units and pillars,
For areas where floor panels other than units are spanned,
The living room is not subject to restrictions on transportation by truck,
You can freely decide the floor plan.
