Description

The present invention relates to an insulated earthquake-resistant panel and an insulated earthquake-resistant wall construction method that allows for easy on-site construction of walls that are both insulated and earthquake-resistant.

Conventionally, in a building, a thermal insulation wall is known that closes the gap between two adjacent columns with rectangular cross sections that have opposing sides, separating the outside and inside of the building (see, for example, Patent Document 1).

The insulated wall in Patent Document 1 is constructed by placing a fiber-based insulation material on the outdoor side and placing a synthetic resin foam board on top of it on the indoor side. As the synthetic resin foam board, synthetic resins such as polystyrene, polyethylene, polypropylene, ethylene vinyl acetate copolymer, ionomer, etc., or foamed mixtures thereof are used. As the fiber-based insulation material, glass fiber, rock wool, etc. are used.

Japanese Utility Model Publication No. 62-26482

However, with the insulated wall of Patent Document 1, in order to strengthen the earthquake resistance of the building, it is necessary to install braces between the columns on-site. It is also necessary to cut, process and install the synthetic resin foam board and fiber-based insulation on-site.

It is also necessary to establish a construction method that will enable the easy creation of insulated earthquake-resistant walls that meet the insulation standards of insulation grade 5 (ZEH level), which will become the standard by fiscal year 2030.

In view of the problems with the conventional technology, the object of the present invention is to provide an insulating seismic panel that allows walls with both thermal insulation and seismic performance to be easily formed on-site.

(1) The heat insulating earthquake resistant panel of the present invention is
A heat-insulating seismic panel used in a building to close the gap between two structures having mutually opposing opposing surfaces adjacent to each other and an outer surface adjacent to the opposing surfaces and facing the outside or underfloor side of the building, thereby separating the outside or underfloor side of the building from the inside or above the floor side,
A rectangular structural surface material whose left and right ends are fixed to the two structures, respectively;
a heat-insulating panel that is fixed to the inner surface or underfloor surface of the structural surface material and has both left and right end surfaces fixed to the two structures,
The insulation panel is characterized in that it is constructed by bonding together a molded insulation material made of bead-method polystyrene foam and a board-shaped insulation material having higher insulation properties than the molded insulation material.

According to the present invention, by preparing the heat-insulating seismic panels in advance at a factory, a wall that is both insulated and earthquake-resistant can be easily formed on-site by simply fixing the heat-insulating seismic panels between two structures.

In addition, because the insulation panel is constructed by bonding the above-mentioned molded insulation material and board-shaped insulation material together, it can provide sufficient insulation within the thickness of the width of the opposing surfaces of the two structures to which both left and right end faces are fixed.

For example, it is easy to construct an insulated seismic panel that can achieve insulation standards of insulation grade 5 (ZEH level), which will become the standard by 2030, and even insulation grades 6 and 7, with a thickness within the width of a typical two-story wooden pillar.

(2) The left and right end faces of the insulating panel may be directly fixed to the two structures, and the left and right end portions of the structural surface material may be positioned laterally outward from the left and right end edges of the insulating panel and fixed to the outer or upper floor (room side) surfaces of the two structures.

As a result, the left and right ends of the structural panel are positioned laterally outboard of the left and right edges of the insulating panel, so that the insulating seismic panel can be easily fixed to the two structures by fixing the left and right ends of the structural panel to the outer surfaces or upper floor surfaces of the two structures at the site.

(3) In the present invention, the left and right ends of the insulation panel are made of frame material, and the left and right end faces are fixed to the opposing surfaces of the two structures via the frame material, and the left and right end faces of the molded insulation material or the board-shaped insulation material located opposite the structural surface material have inclined surfaces that incline toward the structural surface material over the left and right frame materials, and the left and right end faces of the structural surface material may be fixed to the opposing surfaces of the two structures.

With this, both left and right ends of the molded insulation material or board-shaped insulation material located opposite the structural surface material have inclined surfaces that slope toward the frame material, so that when fixing the insulated earthquake-resistant panel between two structures on-site, nailing space can be secured to fix the left and right frame materials to the opposing surfaces of the two structures.

(4) The heat insulating panel is
A lower end plate is fixed to the lower end surfaces of the molded insulation material and the board-shaped insulation material and constitutes the lower end surface of the insulation panel;
An upper end plate that is fixed to the upper end surfaces of the molded insulation material and the board-shaped insulation material and that constitutes the upper end surface of the insulation panel;
It may also be provided with a partition wall having a lower end surface fixed to the center of the lower end plate and an upper end surface fixed to the center of the upper end plate, dividing the molded insulation material and the board-shaped insulation material into left and right halves and fixed to the opposing end surfaces between them.

This makes it possible to provide an insulating earthquake-resistant panel that is easy to handle, has the right size and strength.

(5) The two structures are two pillars having the opposing surface and the outer surface,
The heat-insulating panel has both left and right end surfaces fixed to the opposing surfaces of the two columns, and both upper and lower end surfaces fixed to the foundation, girder or eaves beam of the building,
The structural panel may have both left and right end portions and both upper and lower end portions located respectively outside the left and right end faces and the upper and lower end faces of the insulation panel, the left and right end portions being fixed to the outer surfaces of the two columns, and the upper and lower end portions being fixed to surfaces of the building's foundation, girder or eaves beam facing the outside of the building.

By producing the heat-insulating earthquake-resistant panels in advance at a factory, large walls with heat insulation and earthquake resistance can be easily formed at the construction site of a typical two-story wooden building by simply fixing the heat-insulating earthquake-resistant panels between each pillar and then to the foundation and girder, or to the girder and eaves beam.

(6) The two structures are two pillars having the opposing surface and the outer surface,
The upper, lower, left and right ends of the heat-insulating panel are made of frame materials,
The left and right end surfaces of the heat-insulating panel and the structural surface material are fixed to the opposing surfaces of the two columns, respectively;
The upper and lower end surfaces of the heat-insulating panel and the structural surface material are fixed to opposing surfaces of the foundation, girder or eaves beam of the building,
Of the molded insulation materials or board-shaped insulation materials, the left and right ends of those located opposite the structural surface material may each have an inclined surface that slopes toward the structural surface material of the building and extends above, below, left, and right toward the framing materials.

With this, both top, bottom, left and right ends of the molded insulation material or board-shaped insulation material located on the opposite side (inside the room) from the structural surface material have inclined surfaces that slope toward the frame material, so that when fixing the insulated earthquake-resistant panel to two pillars at the site, nailing space can be secured to fix the top, bottom, left and right frame materials to the opposing surfaces of the two pillars and to the foundation, girth or eaves beam of the building. Therefore, a solid wall can be easily formed between the two pillars.

(7) In the present invention, the heat-insulating earthquake-resistant panel is used to form a wall between two columns in a case where a gypsum board that covers the inside of the heat-insulating panel in the building is fixed to the surface of the two columns opposite to the outer surface, and an in-wall installation such as a hold-down metal fitting, a column head/column foot metal fitting, an outlet box, a switch box, etc. is provided on the back side of the gypsum board,
The insulation panel may have an absence area where the shaped insulation material is placed inside the board-shaped insulation material in the building and where the shaped insulation material is not present in order to avoid interference with the in-wall installation.

By creating the heat-insulating seismic panels with the above-mentioned free areas in advance at the factory, it is possible to simply align the free areas of the molded insulation material with the positions of the items placed inside the wall and fix the heat-insulating seismic panels on-site between each column and between the sill and the girth or between the girth and the eaves beams, and easily form a wall with heat insulation and seismic resistance without interfering with the items placed inside the wall.

(8) In the present invention, the molded insulation material may contain carbon particles and have a product density within the range of 8 to 30 kg/ ^m3 . This makes it possible to provide a heat-insulating earthquake-resistant panel that is easy to mold, has high heat insulation properties, and is lightweight and easy to handle.

(9) In the insulated earthquake-resistant wall construction method of the present invention, the shaped insulation material of the above-mentioned insulating panel is placed inside the board-shaped insulation material, and an insulating earthquake-resistant panel is used that is shaped so that there is an absence area where the shaped insulation material is not present in order to avoid interference with objects placed inside the wall.

That is, the method for constructing a heat-insulated earthquake-resistant wall of the present invention includes a panel fixing step of fixing the heat-insulated earthquake-resistant panel between two adjacent columns of a building and between the foundation and the girth or between the girth and the eaves beam so that an object to be placed inside the wall of the building is located in an area where no molded insulation material of the heat-insulated earthquake-resistant panel is present;
The method is characterized in that after the panel fixing process, a spray filling process is performed in which rigid urethane insulation material is sprayed and filled into areas where the molded insulation material is not present.

According to the insulated earthquake-resistant wall construction method of the present invention, by manufacturing in a factory an insulated earthquake-resistant panel that is molded so that there are areas where the above-mentioned molded insulation material is not present, at the site, this insulated earthquake-resistant panel is attached between the columns according to the panel fixing process, and in the spray filling process, rigid urethane insulation material is simply sprayed into the areas where there is no molded insulation material, thereby forming a wall that has insulation and earthquake resistance without interfering with items placed inside the wall.

(10) In another heat-insulating earthquake-resistant wall construction method of the present invention,
A panel fixing process in which a heat-insulating seismic panel similar to the above method is fixed between two adjacent columns of a building and between the foundation and the girth or between the girth and the eaves beam so that an in-wall installation in the building is located in an area where no molded insulation material of the heat-insulating seismic panel is present;
After the panel fixing process, a cover plate fixing process is performed to fix a heat-insulating cover plate having a material similar to that of the molded insulation material at a position that does not interfere with the wall-mounted objects in the absence of the molded insulation material;
After the cover plate fixing process, a remaining portion filling process is performed in which rigid urethane insulation is sprayed and filled into the remaining portion other than the portion to which the heat-insulating cover plate is fixed in the absence area where the molded insulation material is not present.

By manufacturing the heat-insulating earthquake-resistant panels in a factory so that there are areas where the above-mentioned molded insulation material is not present, at the work site, the heat-insulating earthquake-resistant panels are attached between the columns according to the panel fixing process, the heat-insulating cover plate is fixed according to the cover plate fixing process, and the remaining parts are filled by spraying hard urethane insulation material in the remaining part filling process, which makes it easy to form a wall that is both insulated and earthquake-resistant without causing interference with items placed inside the wall.

FIG. 5 is a perspective view showing a heat-insulating earthquake-resistant panel according to a second embodiment of the present invention. FIG. 3 is a cross-sectional view of the insulating seismic panel of FIG. 2. 11A and 11B are diagrams showing how a thermally insulated earthquake-resistant wall is formed using a thermally insulated earthquake-resistant panel according to a third embodiment of the present invention.

Below, an embodiment of the present invention will be described with reference to the drawings. Figures 1(a) to (c) show a heat-insulating earthquake-resistant panel according to one embodiment of the present invention. As shown in Figure 1, this heat-insulating earthquake-resistant panel 1 is used in a typical two-story wooden building to form a large wall that blocks the space between two structural columns 4, each having adjacent opposing faces 2 facing each other and an outer face 3 adjacent to the opposing faces 2 and facing the outside of the building, to separate the outside from the inside of the building.

The insulated earthquake-resistant panel 1 comprises a rectangular structural panel 5, the left and right ends of which are fixed to two columns 4, and an insulating panel 6, which is fixed to the inside surface of the structural panel 5 and has both left and right end faces directly fixed to the two columns. The insulating panel 6 is made by bonding together molded insulating material 7 made of bead-method polystyrene foam and board-shaped insulating material 8, which has higher insulating properties than this.

In this embodiment, the molded insulation material 7 is disposed inside the board-shaped insulation material 8. The molded insulation material 7 contains carbon particles and has a product density in the range of 8 to 30 kg/ ^m3 .

The insulation panel 6 also includes a lower end plate 9 that is fixed to the lower end surfaces of the molded insulation material 7 and the board-shaped insulation material 8 and forms the lower end surface of the insulation panel 6, an upper end plate 10 that is fixed to the upper end surfaces of the molded insulation material 7 and the board-shaped insulation material 8 and forms the upper end surface of the insulation panel 6, and a stud 11 whose upper end surface is fixed to the center of the upper end plate 10 and whose lower end surface is fixed to the center of the lower end plate 9.

The studs 11 are fixed to the opposing end faces between the molded insulation material 7 and the board-shaped insulation material 8, dividing them into left and right halves. The lower end plate 9, upper end plate 10, and the end faces of the studs 11 facing the outside of the building are fixed to the structural panel 5. The insulation panel 6 has both left and right end faces fixed to the opposing faces 2 of the two columns 4, and both top and bottom end faces fixed to the foundation or girth 12 and girth or eaves beam 13 of the building.

The left and right ends and the top and bottom ends of the structural panel 5 are located laterally and vertically outboard of the left and right end faces and top and bottom end faces of the insulation panel 6, respectively, and the left and right ends are fixed to the outer surfaces 3 of the two columns 4, and the top and bottom ends are fixed to the surfaces of the foundation or girth 12 and girth or eaves beam 13 of the building that face the outside of the building.

When the insulating seismic panel 1 is used to form a large wall in a two-story wooden building, the insulating seismic panel 1 is manufactured in advance at a factory. Then, when the large wall of the first floor is formed on-site, both left and right end faces of the insulating panel 6 of the insulating seismic panel 1 are fixed to the opposing faces 2 of two adjacent columns 4 on the first floor.

The left and right ends of the structural panel 5 are fixed to the outer surfaces of the two columns 4. The upper and lower end faces of the insulation panel 6 are fixed to the opposing surfaces of the base 12 and the girder 13. The upper and lower end faces of the structural panel 5 are fixed to the outer surfaces of the base 12 and the girder 13. This completes the formation of the large wall on the first floor.

On the other hand, when forming a large wall on the second floor, both left and right end faces of the insulating panel 6 of the insulating earthquake-resistant panel 1 are fixed to the opposing faces 2 of two adjacent columns 4 on the second floor. In addition, both left and right end ends of the structural panel 5 are fixed to the outer faces of the two columns 4.

The upper and lower end faces of the insulation panel 6 are fixed to the opposing faces of the girth 12 and eaves beam 13. Furthermore, the upper and lower end ends of the structural panel 5 are fixed to the outer faces of the girth 12 and eaves beam 13. This completes the formation of the large wall for the second floor.

As described above, according to this embodiment, by preparing the heat-insulating earthquake-resistant panel 1 in advance at the factory, a large wall with heat insulation and earthquake resistance can be easily formed at the site by simply fixing the heat-insulating earthquake-resistant panel between two columns 4 and between the base or girth 12 and the girth or eaves beam 13.

In addition, since the insulation panel 6 is constructed by bonding the above-mentioned molded insulation material 7 and board-shaped insulation material 8 together, it can provide sufficient insulation within the thickness of the width of the opposing faces of the two columns 4 to which both the left and right end faces of the insulation panel 6 are fixed.

For example, it is easy to construct an insulated earthquake-resistant panel 1 that can achieve insulation standards of insulation grade 5 (ZEH level), which will become the standard by 2030, and even insulation grades 6 and 7, with a thickness within the width of a pillar 4 of a typical two-story wooden building.

Figure 2 is a perspective view showing the heat-insulating earthquake-resistant panel according to the second embodiment of the present invention as seen from the inside, and Figure 3 is a cross-sectional view showing the same part of this heat-insulating earthquake-resistant panel as Figure 1(c). As shown in Figures 2 and 3, this heat-insulating earthquake-resistant panel 1b is used in a typical two-story wooden building to form a solid wall that closes the gap between two columns 4, each having an opposing surface 2 that faces each other and an outer surface 3 adjacent to the opposing surface 2 and facing the outside of the building, separating the outside from the inside of the building.

The top, bottom, left and right ends of the insulated earthquake-resistant panel 1b are made up of frame material 14, the structural surface material 5b has the same area as the insulating panel 6b, and the left and right end faces of the insulating panel 6b and the structural surface material 5b are fixed to the opposing faces 2 of the two columns 4. The top and bottom end faces of the insulating panel 6b and the structural surface material 5b are fixed to the opposing faces of the foundation or girth 12 and girth or eaves beam 13 (see Figure 1) of the building.

Of the molded insulation materials 7b or board-shaped insulation materials 8b, those located on the inside of the building have both top, bottom, left and right ends with inclined surfaces 15 that slope toward the outside of the building (frame material 14 side) toward the top, bottom, left and right frame materials 14. In this embodiment, the molded insulation material 7b is located on the inside of the board-shaped insulation material 8b and has inclined surfaces 15.

When the insulating seismic panel 1b is used to form a large wall in a two-story wooden building, the insulating seismic panel 1b is manufactured in advance at a factory. Then, when the main wall of the first floor is formed on-site, the left and right end faces of the insulating panel 6b and structural surface material 5b of the insulating seismic panel 1b are fixed to the opposing faces 2 of two adjacent columns 4 on the first floor.

At this time, the insulation panel 6b is fixed to the opposing surface 2 by nailing the frame material 14 of the insulation panel 6b to the opposing surface 2, but since the inclined surfaces 15 at both the left and right ends of the insulation panel 6b ensure nailing space, nailing can be done without any problems. Also, the upper and lower end faces of the insulation panel 6b and the structural surface material 5b are fixed by nailing the corresponding frame material 14 to the mutually opposing surfaces of the foundation 12 and the girth 13. In this case too, since the inclined surfaces 15 at both the upper and lower ends of the insulation panel 6b ensure nailing space, nailing can be done without any problems. In this way, the solid wall of the first floor is formed.

On the other hand, when forming a solid wall on the second floor, the left and right end faces of the insulating panel 6b and structural surface material 5b of the insulating seismic panel 1b are fixed to the opposing faces 2 of two adjacent columns 4 on the second floor. In this case as well, the frame material 14 of the insulating panel 6b is nailed and fixed to the opposing faces 2 without any hindrance. Also, the upper and lower end faces of the insulating panel 6 and structural surface material 5b are fixed by nailing the corresponding frame material 14 to the mutually opposing faces of the girth 12 and eaves beam 13 without any hindrance. In this way, the solid wall on the second floor is formed.

As described above, according to the second embodiment of the insulated earthquake-resistant panel 1b, by preparing the insulated earthquake-resistant panel 1b in advance at a factory, at the construction site of a typical two-story wooden building, the insulated earthquake-resistant panel 1b and the structural panel 5b can be simply fixed between each of the columns 4 and to the foundation or girth 12 and the girth or eaves beam 13, and solid walls with thermal insulation and earthquake resistance can be easily formed on the first and second floors.

In addition, since the insulation panel 6b has inclined surfaces 15 on the top, bottom, left and right, the frame materials 14 on the top, bottom, left and right of the insulation panel 6b can be easily nailed to the opposing surfaces 2 of the columns 4 on both sides, as well as to the base or girth 12, and the girth or eaves beam 13, to fix the insulation panel 6b. In addition, the same effects regarding insulation performance as in the first embodiment can be obtained.

Figure 4 shows how a large wall is formed between two columns 4 using a heat-insulating earthquake-resistant panel 1c according to the third embodiment of the present invention. As shown in Figure 4, this heat-insulating earthquake-resistant panel 1c is used to form a large wall between two columns 4 when a gypsum board 16 (see Figure 1) that covers the inside of the heat-insulating panel 6c is fixed to the surface opposite the outer surface 3 of the two columns 4, and when in-wall installation items 17 such as hold-down hardware, column head and column foot hardware, outlet box, and switch box are provided on the back side of the gypsum board 16.

The insulated earthquake-resistant panel 1c is manufactured by replacing the molded insulation material 7 in the insulated earthquake-resistant panel 1 of the first embodiment with molded insulation material 7c having an absence area 18 (shaded area) where no molded insulation material is present in order to avoid interference with the in-wall placement object 17.

Since the molded insulation material 7c having the absent area 18 (shaded area) is made of bead-method polystyrene foam, it can be easily molded using a mold of a shape that corresponds to the molded insulation material 7c. Therefore, the position, size, and shape of the absent area 18 in the molded insulation material 7c can be easily set by selecting a mold according to the position, size, and shape of the in-wall object 17.

When a large wall is formed between two columns 4 using the heat-insulating seismic panel 1c, as shown in Figure 4, the in-wall placement object 17 is positioned in the absence area 18 (shaded area in Figure 4) where the molded insulation material 7c of the heat-insulating seismic panel 1c is not present between the two columns 4 and between the base 12 and the girder 13 (when a large wall is built on the first floor) or between the girder 12 and the eaves beam 13 (when a large wall is built on the second floor), and is fixed in the same manner as in the first embodiment (panel fixing process).

Next, an insulation cover plate 19 made of the same material as the molded insulation material 7c is fixed in a position in the absent area 18 that does not interfere with the in-wall arrangement 17 (cover plate fixing process). Next, the remaining part of the absent area 18 other than the part where the insulation cover plate 19 is fixed is filled with rigid urethane insulation material 20 by spraying (remaining part filling process). This completes the formation of the large wall, and then the gypsum board 16 (see Figure 1) that covers the inside of this large wall is fixed between the two pillars 4.

In addition, instead of the cover plate fixing process for fixing the heat-retaining cover plate 19 and the remaining portion filling process for spraying and filling the remaining portion with hard urethane insulation material, a spray filling process may be performed in which the entire unoccupied area 18 is filled with hard urethane insulation material 20 by spraying it.

As described above, according to the third embodiment, the insulated earthquake-resistant panel 1c having the above-mentioned absent area 18 where no molded insulation material is present is manufactured in a factory, and then at the site, this insulated earthquake-resistant panel 1c is attached between the columns 4 according to the panel fixing process, and the absent area 18 can be covered with a heat-retaining cover plate 19 or hard urethane insulation material 20 by the cover plate fixing process and remaining part filling process or by the spray filling process.

Therefore, even between two columns 4 where an in-wall placement object 17 exists, a large wall having the same performance as that of the first embodiment having thermal insulation and earthquake resistance can be formed. Note that a solid wall may be formed between two columns 4 in the same manner by using the thermal insulation earthquake-resistant panel 1b of the second embodiment that has a similar non-existent area 18.

Although the embodiment of the present invention has been described above, the present invention is not limited thereto. For example, the left and right end faces of the insulating panel may be directly fixed to two structures other than columns, and the left and right end portions of the structural surface material may be positioned outward in the left-right direction from the left and right end edges of the insulating panel, and fixed to the outer surface or the upper floor surface (inside the room) of the two structures.

In this case, by using rafters as the two structures, the insulated earthquake-resistant panels can be used to form the roof of a building. Also, by using joists as the two structures, they can be used to form the floor of a building.

The insulating panel may also be one in which the left and right ends are made of frame material, the left and right end faces are fixed via the frame material to the opposing surfaces of two structures other than columns, the left and right end faces of the molded insulating material or board-shaped insulating material located opposite the structural surface material have inclined surfaces that slope toward the structural surface material over the left and right frame materials, and the left and right end faces of the structural surface material are fixed to the opposing surfaces of the two structures that face each other.

In this case, by using rafters as the two structures, the heat-insulating earthquake-resistant panel can be used to form the roof of a building. Also, by using joists as the two structures, it can also be used to form the floor of a building. Also, because the heat-insulating panel has an inclined surface, it has the advantage of providing nailing space to secure the frame material, just like in the second embodiment.

(1) The heat insulating earthquake resistant panel of the present invention is

The heat-insulating earthquake-resistant panel is used to form a wall between the two columns when a hold-down metal fitting, a column head/column foot metal fitting, an outlet box, a switch box, or other in-wall installation items are provided between the two columns,
The insulation panel is characterized in that the shaped insulation material is placed inside the board-shaped insulation material in the building, and has an absent area where the shaped insulation material is not present in order to avoid interference with items placed inside the wall .

According to the present invention, by preparing the heat-insulating earthquake-resistant panel in advance at the factory, a wall having both heat insulation and earthquake resistance can be easily formed at the site simply by fixing the heat-insulating earthquake-resistant panel between two pillars .

Furthermore, since the insulation panel is constructed by bonding the above-mentioned molded insulation material and board-shaped insulation material together, it can provide sufficient insulation effect within a thickness within the width of the opposing surfaces of the two pillars to which both left and right end faces are fixed.

For example, it is possible to easily construct an insulated earthquake-resistant panel that can achieve insulation standards of insulation grade 5 (ZEH level), which will become the standard by 2030, or even insulation grades 6 and 7, with a thickness within the width of a typical two-story wooden pillar.
Furthermore, by preparing the insulated earthquake-resistant panel having the above-mentioned absence range in the factory, it is possible to easily form a wall that has both thermal insulation and earthquake resistance performance at the site without interfering with the items placed within the wall by simply fixing this insulated earthquake-resistant panel between each pillar while aligning the absence range of the molded insulation material with the position of the items placed within the wall.

(2) The insulating panel has both left and right end surfaces directly fixed to the two columns , respectively, and both left and right end portions of the structural surface material are positioned laterally outward from both left and right end edges of the insulating panel and are fixed to the outer surfaces of the two columns .

According to this, the left and right ends of the structural panel are positioned further left-right than the left and right edges of the insulated panel, so that the insulated earthquake-resistant panel can be easily fixed to the two columns at the site by fixing the left and right ends of the structural panel to the outer surfaces of the two columns .

(3) In this case, the upper and lower end faces of the insulating panel are fixed to the foundation, girder or eaves beam of the building, and the upper and lower end ends of the structural surface material are located vertically outboard of the upper and lower end faces of the insulating panel, and the upper and lower end ends are fixed to the surfaces of the foundation, girder or eaves beam of the building that face the outside of the building.

According to this method, by preparing the insulating earthquake-resistant panels in advance at a factory, at the construction site of a typical two-story wooden building, it is possible to easily form a large wall with insulating and earthquake-resistant properties by simply fixing these insulating earthquake-resistant panels between each pillar and then to the foundation and girder beams, or the girder beams and eaves beams.
