And the rug screw bolts 64 and the like are fastened to the two holes of the metal fittings 63 to connect the right and left end faces of each of the wall structural members in close contact with each other. As means for connecting the left and right end surfaces of the wall structural members to each other, in addition to the means shown in FIGS. 6, 7, and 8, as shown in FIG. 9, each of the wall structural members 2A, 2B, 2C and For example, at each of two places on the left and right end surfaces of the left and right end surfaces of the 2D, each horizontal hole 66 to which a steel pipe 65 can be attached is provided in advance, and in each of the left and right end surfaces of the close wall structure material, the respective horizontal holes 66 are provided. After the steel pipe 65 is attached, a steel wedge 69 is struck into each small hole 68 provided in the steel pipe 65 from the upper surface side of the wall structural member, and the right and left end faces of each wall structural member are connected to each other. You may do it. In addition, the wall structural members 2A to 2A
In order to connect the left and right end faces of D with each other, FIGS.
In addition, it goes without saying that various existing connecting tools and connecting means can be appropriately used. Further, as shown in FIG. 1, FIG. 2, FIG. 3, and FIG. 4, each corner of the wall structural members 2A and 2B, 2A and 2C, 2B and 2D, and 2C and 2D An appropriate number of shape fittings 23 are arranged and connected to each other at each corner of the wall structural members 2A and 2B, 2A and 2C, 2B and 2D, and 2C and 2D. FIG. 5, as described above,
Each wall structural material 2A and 2B, 2A and 2C, 2B and 2D, 2C
L-shaped fitting 23 for connecting the corners of 2D and 2D
Is enlarged and illustrated. In addition, wall structure material 2A
It is a matter of course that various existing connecting tools and connecting means can be appropriately used for connecting the respective corners of the first and second corners 2B, 2A and 2C, 2B and 2D, and 2C and 2D. Then, as shown in FIG. 4, a roof part 3 is constructed on the upper part of each of the wall structural members 2A to 2D which are fixedly connected to each other on the building foundation 1 to form a building 10. is there. Each said wall structural material 2A,
In 2B and 2C, for example, openings 4a, 4b and 4c for attaching a sash window, for example, are previously processed in a factory or the like. In the wall structural member 2D, for example, an opening 5 for attaching a front door is preliminarily processed in a factory or the like.
Each of the novel wooden wall structural materials 2A to 2D of the present invention described above.
For example, as shown in FIG. 6, two wall structural members 2A to 2D each use two wooden plate members 11 of the same shape and bond the opposing surfaces of the two plate members 11 to each other. The wall structure base material 30 formed as a double structure by bonding with the agent is used, and a plurality of, for example, five wall structure base materials 30 are used. The five wall structure bases 30 are integrated with each other while attaching and joining, for example, a small wooden connecting member 12 along a vertically long groove 70 provided on each of the left and right end surfaces of each wall structure base 30. Into a single panel. In this case, the wall structure base material 3 used to form one panel-like wall structure material
The number of zeros can be set freely in various ways according to the design contents of the building 10 in addition to the illustrated example. Each of the plate members 11 does not necessarily have to be of the same shape made of two pieces of wood, but may have different shapes. Reference numeral 19 in FIG. 6 indicates an adhesive bonding portion. The width, height, and thickness of each of the wall structural members 2A to 2D formed as a single panel can be freely set according to the design contents of the building 10. The one panel-shaped wall structural material 2A to 2D can be formed as in the example shown in FIG. 6, and as shown in FIG. 7 or FIG. 8, a large number of thin wooden pieces 11 ′ having the same shape. Each of the plurality of plate members 11 'may be bonded to each other with an adhesive to form a multi-layered plywood shape to form a single panel-shaped wall structure material. The plate members 11 'need not necessarily have the same shape of a large number of wooden pieces, but may have different thicknesses and shapes. In this case, the width, height, and thickness of the wall structural members 2A to 2D formed as a single panel can be freely set according to the design contents of the building 10. According to each of the novel wooden wall structural materials of the present invention described above, it is possible to utilize the specific effects of heat insulation, sound insulation, and moisture absorption of wood, and this wall structural material itself can be used as an outer wall of a building, When the wall is constructed using only the wall structural material by simultaneously using the inner wall, the livability of the user can be improved. According to the above-described wall building method, the outer wall and the inner wall of the building are simultaneously used by using the wall structural materials 2A to 2D capable of improving the livability described above, and the constituent materials are reduced as a whole. Thus, it is possible to provide a building 10 that does not require a great deal of skill, can shorten the construction period and reduce labor costs, and can realize uniform and low construction costs. Further, the outer and inner walls of the building 10 are not made of synthetic resin at all by the wall structural materials 2A to 2D, and the internal frame structure is constructed by using columns, beams and the like as in the conventional construction. It can be built at once without the hassle of doing
An environment-friendly building 10 can be built in combination with the characteristics of sound insulation and moisture absorption. In the above-described example, the case where the house-like building 10 is constructed has been described. In addition, the present invention is applicable to various wooden buildings such as school buildings, auditoriums, gymnasiums, and public halls.

According to the wall structural material of the present invention, the outer wall and the inner wall of a building can be used simultaneously, and the livability can be improved by the unique functions of heat insulation, sound insulation and moisture absorption of wood. It is possible to provide a wall structure material of a building that can be manufactured. Further, according to the wall construction method of the present invention, the outer wall and the inner wall of the building can be used simultaneously, and the constituent materials as a whole can be reduced, the construction period can be shortened, and the labor cost can be reduced. It is possible to provide a wall construction method capable of realizing cost reduction.
