A roof structure consisting of the ceiling joists 22 can be mounted.

The advantages of the construction method of the present invention as described above are listed as follows: (1) It is possible to make each of the first basic material and the second basic material thinner and lighter without impairing the strength of the wall. Since it can be lifted by itself, it can be easily lifted by itself, and it is safe even when piled up on a high place, and does not require mechanical power such as a crane.

(2) The first and second multilayer wall materials are fitted to each other in the fitting portions or in the fitting holes with the fitting portions up and down, left and right,
Further, since it is a multi-walled cross-girder structure that is fixedly engaged and fixed to the crossing wall that overlaps vertically by the engaging portion and the locking portion,
A structure that is structurally stable against external force can be constructed without using dowels or through bolts.

(3) Since the structure to be constructed is an integral structure of a multi-layer wall composed of an outer wall and an inner wall, external forces can be dispersed and received, so that the structure can be obtained without making the wall unnecessarily thick. The material can be made firmly, the material is not wasted, and resources can be saved.

(4) Since the layers of the outer wall and the inner wall of the first and second multi-layer wall materials are shifted from each other and closely adhere to each other, as in the case of a conventional girder structure such as a log house. ,
There is no need to fill the gap between the upper and lower material joining surfaces by caulking, to provide an engaging groove for close contact, or to perform actual processing of unevenness.

(5) By simply changing the width of the groove in the basic material, a double-wall, triple, quadruple or multi-layer wall cross-girder structure having an arbitrary thickness can be produced. It is possible to make various structures that meet the conditions.

(6) If a standardized material such as a 2 × 4 material is used, the labor required for processing is only required to be at the groove at the intersection of the walls. , Can be the same shape, if rectangular, the facing walls will have the same shape, easy to process and assemble, easy workability, no assembly skills and experience required, anyone can assemble be able to.

(7) There is no need to use thick logs or square lumber,
Since a plate material which was not strong enough to be used as a structural material and a 2 × 4 material widely distributed in the market can be used, a structure can be constructed at low cost without cost.

(8) Since no nails, bolts, dowels, etc. are required to assemble the wall, it is easy to disassemble and reassemble.

(9) The basic material is not limited to wood, and various materials such as plastic, ceramic, metal, cement board, wood board, and cardboard can be used as long as they satisfy the required strength. By combining the basic materials of these materials having different properties over part or all of the multi-layer wall to form a multi-layer wall material made of a composite material and constructing the wall surface, the performance of the multi-wall cross-girder structure is improved. If a basic material made of a material having excellent heat insulation properties is used for the intermediate layer between the outer wall and the inner wall of the multilayer wall material, a multi-walled girder structure having excellent heat insulation properties can be produced.

(10) The outer wall layer is made of a basic material made of a fire-resistant material, and the inner wall layer is made of a basic material made of wood to form a multilayer wall. The wood portion of the inner wall layer protruding from the outer wall is made of a fire-resistant material. If covered with the material, the fire prevention performance can be improved without impairing the livability on the indoor side.

(11) By utilizing such a multi-layer wall, it is possible to improve waterproofness, indestructibility, weather resistance, etc. by using the same method while maintaining the integral structure of the wall. .

(12) By using the wall construction method according to the present invention, a rectangular or polygonal cross-girder box having a wall surface made of a multilayer wall material is formed, and a bottom plate having an appropriate shape is fixed, or the bottom plate is fixed. A base composed of a starter or a starter and a basic material is fixed thereon, and a box of a multi-walled girder set is assembled from the basic material as described above using the starting material as a starting point, and a lid is provided as necessary, a box, a container, You can make boxes, containers, packages, etc.

[0049]

In summary, according to the invention of the present application, the wall intersections are fixed by the grooves while the basic members are locked up, down, left and right, and the plurality of basic members fitted into the grooves are more strongly rubbed by the friction. Since the outer walls and inner walls composed of the multi-layer wall material are stacked in a mutually shifted state, even if the basic material is a light and thin plate, it is strong and stable, In addition, a cross-girder structure having excellent airtightness can be constructed.
