Description

[Technical Field]

[0001] The present invention relates to a building and a method for constructing a building. [Background technology]

[0002] BACKGROUND ART Conventionally, as a construction method for a building, for example, in the case of a wooden house, a framework construction method or a frame construction method has been used. In the post and beam construction method, a framework consisting of columns, cross members (bases, beams, etc.), bracing, etc. is constructed on a concrete foundation. In the wood frame construction method, a framework is constructed on a concrete foundation by fixing structural plywood or other surface materials to a rectangular framework consisting of vertical, upper, and lower frames. Regardless of the construction method used, wooden houses have insulation placed within the walls of the framework, such as foam insulation made from petroleum or inorganic materials like glass wool or rock wool.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2008-127854 Summary of the Invention [Problem to be solved by the invention]

[0004] Conventional buildings have the following problems: <1> Since insulation is placed inside the walls of the building structure, the cost of building materials is high. <2> Heat insulation materials use raw materials and have a large environmental impact. <3> When a building is destroyed by an earthquake or fire, the insulation material is generated as waste, resulting in high disposal costs. Furthermore, rebuilding the building also requires high costs for building materials and construction. <4> The high costs of demolition and reconstruction make it difficult to renovate buildings to suit their life cycle.

[0005] The present invention has been made in view of the above points, and its object is to provide at least one of the following buildings and a method for constructing a building. <1> Low building material and construction costs for new construction and reconstruction <2> Small environmental impact <3> Easy to renovate according to the life cycle of the property [Means for solving the problem]

[0006] The present application provides a building having a concrete foundation and a main body formed by combining columnar structural materials on the foundation, and the wall portion is constructed by placing a shielding body, which is a bag body filled with a gaseous filling material, in the space surrounded by the structural materials. The wall portion may have an exterior wall panel fixed to the outer surface of the skeleton, or may have an interior panel fixed to the inner surface of the skeleton. The exterior wall panel may have a protective layer made of paint on the surface thereof.

[0007] The present application also provides a method for constructing a building, comprising: a foundation construction step of constructing a concrete foundation; a body construction step of constructing a body by combining columnar structural materials on the foundation; and a wall construction step of constructing a wall by placing a shielding body, the inside of which is a bag filled with a gaseous filling material, in a space surrounded by the structural materials of the body. In the wall surface construction step, an exterior wall panel may be fixed to the outer surface of the skeleton. In the wall surface construction step, a protective layer made of paint may be formed on the surface of the exterior wall panel. In the wall surface construction step, an interior panel may be fixed to an inner surface of the skeleton. In the wall portion construction process, the shielding body may be placed in the space with the filler filled inside the bag body, or the filler may be filled inside the bag body after the bag body is placed in the space. [Effects of the Invention]

[0008] The present invention has at least one of the following advantages. <1> The shielding body is constructed by filling a flexible bag with a gaseous filler and inflating the bag, so the building material costs and construction costs for new construction and rebuilding are low. <2> Since it does not use conventional insulation materials, it has a small environmental impact. <3> By removing the filling material, it can be easily removed from the wall, dismantled, and disposed of, reducing the cost of dismantling and rebuilding, and making it easy to renovate according to the life cycle of the building.

[0010] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. [Example 1]

[0011] <1> building In this embodiment, a building of the present invention, which is a wooden house made of wooden structural materials, will be described.

[0012] <2> Overall configuration (Fig. 1) The building of the present invention has a concrete foundation 1 and a skeleton 2 formed by combining columnar structural members such as pillars 21, bases 22, and beams 23 on top of the foundation 1. Wall surface portions 3 are formed by fixing interior panels 31 to the surfaces of the pillars 21, bases 22, and beams 23 inside the building (indoor side), and exterior wall panels 32 to the surfaces of the pillars 21, bases 22, and beams 23 outside the building (outdoor side), respectively, and a shielding body 33 is disposed inside the wall surface portions 3 surrounded by structural members such as the pillars 21, bases 22, and beams 23.

[0013] <3> shield The shield 33 is constructed by filling a flexible bag 33a with a gaseous filler 33b to inflate the bag 33a (FIG. 2). The shielding body 33 is made of, for example, a bag body 33a made of a resin such as butyl rubber and a filler body 33b made of nitrogen gas, so that the wall surface portion 3 can be constructed inexpensively, and the cost of building materials is low. In addition, by appropriately selecting the gas used for the filler body 33b, various functions can be added to the building, such as high thermal insulation and fire prevention. Furthermore, it has a smaller environmental impact than conventional insulation materials. Even if the filler 33b falls out of the shield 33, it is possible to fill the shield 33 with the filler 33b later. Also, it is possible to monitor the pressure of the filler 33b with a pressure sensor, and to automatically fill the filler 33b from a compressor, a cylinder, or the like when the pressure drops.

[0014] <4> Covering Effects By providing the shielding body 33 on the wall surface portion 3, a shielding layer is formed on the wall surface portion 3 by the filler 33b, resulting in a building with high thermal and sound insulation performance. Furthermore, because the shielding body 33 is lightweight, the building is also lightweight, resulting in a highly earthquake-resistant building. In particular, because the shielding body 33 has a predetermined elasticity, it deforms in accordance with deformation of the main body 2 caused by an earthquake, without being damaged, and also has a vibration-damping function due to elastic deformation. Note that, if necessary, bracing or the like may be provided in the internal space of the wall portion 3 in which the shielding body 33 is placed. Because the shielding body 33 has a predetermined elasticity, it can be deformed and placed even if bracing or the like is present in the internal space. Furthermore, since the shielding body 33 is a bag body 33a filled with filler 33b, it can be easily removed from the wall portion 3, dismantled and disposed of by removing the filler 33b, which reduces the cost of dismantling and rebuilding, making it a building that can be easily renovated to suit its life cycle.

[0015] <5> Interior and exterior decoration of buildings The wall portion 3 is constructed by fixing an interior panel 31 and an exterior wall panel 32 to the frame 2. The interior panel 31 is a board, and wallpaper is pasted on the surface. Note that, without using the interior panel 31, wallpaper can be pasted directly on the frame 2 and the shielding body 33 to simplify the interior construction work. Using decorative panels for the exterior wall panels 32 allows for a wide range of designs and makes it easy to construct an exterior wall surface. The exterior wall surface can also be painted to form a protective layer 34. In this case, by using LINE-X (registered trademark) as the paint to form the protective layer 34, an exterior wall with excellent durability and soundproofing properties can be constructed.

[0016] <6> How the building was constructed Next, a method for constructing a building according to the present invention will be described.

[0017] <6.1>Foundation construction process As in the past, a concrete foundation 1 (raft foundation) is constructed on the ground.

[0018] <6.2> Framework construction process After the foundation 1 is constructed, the skeleton 2 is constructed on the foundation 1 by combining pillar-shaped structural members such as pillars 21, bases 22, and beams 23 as in the conventional method.

[0019] <6.3> Wall construction process A shield 33, which will become the wall portion 3, is placed in a pre-inflated state in the space surrounded by the pillars 21, base 22, beams 23, etc. of the skeleton 2. The shield 33 may be fixed to the skeleton 2 with an adhesive or the like. When transported to a construction site, the bag 33a is brought in before being inflated, making it easy to transport and transport. Furthermore, since the shielding body 33 is made by filling the inside of the bag 33a with the filler 33b, it is lightweight and can be installed by a small number of people in a short time, resulting in low construction costs. Furthermore, noise and vibration during construction are also reduced. After the shielding body 33 is installed, the interior panel 31 is fixed to the inner surface of the pillar 21, the base 22 and the beam 23, and the exterior wall panel 32 is fixed to the outer surface, sealing the shielding body 33 and constructing the wall portion 3. The shielding body 33 is not limited to being installed in a pre-inflated state; the bag body 33a may be placed in a space surrounded by pillars 21, foundations 22, beams 23, etc., and sealed with the interior panel 31 and exterior wall panel 32, after which the filler 33b may be introduced and filled into the bag body 33a.

[0020] <6.4> Interior and exterior construction process On the inside of the wall surface portion 3, wallpaper is pasted on the surface of the interior panel 31. When the interior panel 31 is not used, wallpaper is pasted on the shielding body 33. On the outside of the wall portion 3, the surface of the exterior wall panel 32 can be painted to form a protective layer 34.

[0021] <Other Examples> In the above-described embodiment, the shielding body 33 is disposed on the wall portion 3, but the shielding body 33 may also be disposed inside a floor structure, a roof structure, or the like. Furthermore, in the above-described embodiment, the present invention is applied to a wooden house made of wooden structural members, but it can also be applied to a steel-framed building using steel as structural members.
