Description

[Technical field]

[0001] The present invention relates to a wall structure for a wooden building, and more particularly to a wall structure for a wooden building that can achieve high thermal insulation and earthquake resistance through an integrated structure. [Background technology]

[0002] Insulation and earthquake resistance are basic performance requirements for a building. In recent years, there has been an increasing demand for energy-efficient homes in order to realize a carbon-free society, and buildings are required to have high insulation performance. The thickness of the insulation material plays a major role in determining this insulation performance. In addition, the earthquake resistance of a building is greatly influenced by the cross-sectional area of ​​its columns. On the other hand, there are panels for wooden houses described in Patent Document 1 that aim to reduce on-site work and achieve high thermal insulation and earthquake resistance by being produced in a factory. This panel for wooden houses comprises a face plate that includes a rigid base plate and a peripheral frame attached to the periphery of the surface that is to be the indoor side, a thermal insulation material attached to the surface that is to be the outdoor side of the base plate with its periphery coinciding with the periphery of the face plate, and a heat-shielding sheet attached to the outside of the thermal insulation material, and is manufactured in a factory to dimensions that match the inside dimensions of the framework material around an opening that is to become a wall surface, and the heat-shielding sheet is attached to the periphery by folding the peripheral portion of the sheet over the periphery of the frame.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] A wall structure 1 for a wooden building according to a first embodiment of the present invention will be described with reference to Figs. 1, 3, and 4, reference numeral 3 denotes a base, and two pillars 7, 7 are provided at a distance from each other in an upright state on the base 3. The lower ends of the base 3 and the pillars 7, 7 are connected and fixed by tenons. The width dimension A1 of the base 3 is set to be 150 mm, 45 mm larger than the width dimension of a base that is normally used. The height dimension A2 of the base 3 is 105 mm. The pillar 7 is a rectangular pillar having a cross-sectional dimension B of 105 mm x 105 mm.

[0016] Reference numeral 9 denotes a beam serving as a cross member, and this beam 9 is placed across the upper end faces of the two columns 7, 7. The upper ends of the columns 7, 7 and the beam 9 are connected and fixed by tenons. The width of the beam 9 is set to be 45 mm larger than the width of a beam normally used, and the width C1 is 150 mm. The height C2 of the beam 9 is 105 mm. Two partitions 11, 11 are placed at a distance from each other between the pillars 7, 7, and the upper and lower ends of the two partitions 11, 11 are connected and fixed to the foundation 3 and the beam 9 by tenons, respectively. The partition 11 is a rectangular column with a vertical side dimension D of 105 mm and a horizontal side dimension E of 45 mm in cross section.

[0017] Reference numeral 13 denotes an exterior wall material composed of a structural surface material or the like, and this exterior wall material 13 is attached to pillars 7, 7 and covers the outer side of the space surrounded by the pillars 7, 7, the foundation 3 and the beams 9. 4 and 5, reference numeral 17 denotes an inner wall material made of a decorative board or the like, and this inner wall material 17 covers the inner surface of the space. Therefore, a space 15 is formed between the exterior wall material 13 and the interior wall material 17 . As mentioned above, the width of the foundation 3 and beam 9 is set to be 45 mm larger than that of the conventional one, so that the extension space 15a is formed. The extension space 15a protrudes toward the inner wall material 17, that is, toward the inside of the building. Therefore, the thickness of the space 15 is increased, and its volume is larger than that of the conventional space.

[0018] Reinforcing columns 7a, 7a are arranged in the extension space 15a, and the reinforcing columns 7a, 7a are fixed to the foundation 3 and the beams 9 with tenons, and the reinforcing columns 7a, 7a are joined to the columns 7, 7. Further, reinforcing studs 11a, 11a are arranged in the extension space 15a, and the reinforcing studs 11a, 11a are fixed to the foundation 3 and the beams 9 with tenons, and the reinforcing studs 11a, 11a are joined to the studs 11, 11. As described above, the reinforcing columns 7a, 7a and reinforcing studs 11a, 11a are provided, so the cross-sectional area of ​​the columns and studs is larger than that of conventional buildings, improving earthquake resistance. In particular, the strength against buckling is increased.

[0019] The space 15 is filled with a heat insulating material 19 made of foamed polyurethane resin. As described above, the thickness of the space 15 is increased, and its volume is larger than that of the conventional space, so that the heat insulating effect is improved. Furthermore, as mentioned above, the extension space 15a protrudes toward the inside of the building, so the distance between the pillars 7, 7 and studs 11, 11 and the interior wall material 17 remains the same as in the conventional case, and there is no adverse effect on earthquake resistance.

[0020] A wall structure for a wooden building according to a second embodiment of the present invention will be described with reference to FIG. Since the wall structure of the wooden building according to the second embodiment has a similar configuration to the wall structure 1 of the wooden building according to the first embodiment, the symbols used in the first embodiment will be quoted in the description, and the symbols used in the first embodiment will be added, and the description will be omitted. The width dimension A3 of the base 33 is 105 mm, and the height dimension A4 is 105 mm. The beam 35 has a width dimension C3 of 105 mm and a height dimension C4 of 105 mm. Reference numeral 37 denotes an additional beam as an additional cross member, and this additional beam 37 is joined and fixed to the surface of the inner wall material 17 of the beam 35 . The width dimension C5 of the additional beam 37 is 45 mm, and the height dimension C6 is 105 mm. The additional beam 37 forms an extension space 15a.

[0021] The reference numeral 39 denotes a floor material, and the end of this floor material 39 on the exterior wall material 13 side is placed on the end of the upper surface of the base 33 on the interior wall material 17 side. Reinforcing pillars 7b and reinforcing studs 11b are installed on the upper surface of floor material 39. The upper ends of the reinforcing columns 7b and the reinforcing studs 11b are fixed with tenons to the additional beams 37. The lengths of the reinforcing columns 7b and the reinforcing studs 11b are shorter than the lengths of the columns 7 and 11 by the thickness of the floor material 39. In the wall structure of the wooden building according to the second embodiment, reinforcing columns 7a, 7a and reinforcing studs 11a, 11a are provided, so the cross-sectional area of ​​the columns and studs is larger than that of conventional buildings, improving earthquake resistance, and in particular the strength against buckling.

[0022] The space 15 is filled with a heat insulating material 19 made of foamed polyurethane resin. As described above, by providing the additional beam 37, the extended space 15a is formed, the thickness dimension of the space 15 is increased, and its volume is larger than that of the conventional space, thereby improving the insulating effect. In the wall structure of a wooden building according to the second embodiment, the foundations 33 and beams 35 can be of the same width as in the conventional case, so that the increase in costs can be kept to a minimum.

[0023] As described above, in the wall structure 1 of a wooden building, by providing the extension space 15a, it is possible to simultaneously improve the thermal insulation and earthquake resistance. Therefore, unlike conventional panels for wooden houses, there is no need to standardize the size to suit factory production. Therefore, it can be easily used for all custom-built houses. Since the wall structure 1 of a wooden building is relatively simple in structure, it is possible to keep costs low.

[0024] Although the embodiment of the present invention has been described in detail above, the specific configuration is not limited to this embodiment, and the invention also includes design changes within the scope of the present invention without departing from the gist of the present invention. For example, the dimensions of the foundation, beams, pillars, studs, reinforcing pillars and reinforcing studs, as well as the extension space, are not limited to those described above, and can be changed depending on the area, layout, etc. of the house. In the above embodiment, a beam is used as the cross member, but the present invention is not limited to this, and a girder or the like may also be used. In the above embodiment, a polyurethane foam resin is used as the heat insulating material, but the present invention is not limited to this, and other heat insulating materials such as glass wool and cellulose fiber may be used. Furthermore, it goes without saying that the number of pillars and studs is not limited to that in the above embodiment. [Industrial Applicability]
