Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a wall structure of a wooden building.

[0002]

2. Description of the Related Art As a wall structure of a wooden building, construction is carried out between a structural body such as a pillar or a horizontal material with an air-permeable layer formed between an inner wall panel and an outer wall panel having a heat insulating material on the outdoor side. These are known, and one example thereof is Japanese Patent Laid-Open No. 2001-2001.
It is disclosed in Japanese Patent Publication No. 207568. In this wall structure, a heat insulating interior panel (1) in which a heat insulating material (12) is integrally attached to the back surface side of a structural face material (11) capable of forming a load bearing wall structure is used. The margins of the four circumferences are directly attached to the structural frame by nailing as mounting pieces (16).

[0003]

DISCLOSURE OF THE INVENTION The inventors of the present invention have attempted to develop a new construction method based on the conventional wooden frame construction method in consideration of various circumstances surrounding the present housing environment. That is,
With the declining birthrate and aging of the population rapidly progressing, there is a demand for a structure that can withstand long-term use and is easy to maintain. Using a house for a long period of time means that the composition and lifestyle of the resident may change during that time, or the resident itself may change, so a structure that can flexibly and variably respond to these changes is required. desired.

In addition, under the present circumstances in which the number of skilled workers is decreasing due to the circumstances of the contractor and the variation in the level of construction technology is increasing, there is an urgent need to develop a construction method and structure that can secure a certain quality without requiring skill. is there. To this end, standardize materials, select materials that can be stably supplied with consistent quality over a long period of time, and basically eliminate the need for on-site processing on the premise of factory processing by precutting. , Simplification of construction contents, mechanization,
It is necessary to promote efficiency, develop materials and construction technologies that are conscious of future reforms, and reduce construction time and costs by shortening the construction period throughout the construction process.

Further, since waste such as waste materials produced by on-site processing is reduced through the common use of members, long-term stable supply of members, and complete precutting of members, these should be promoted from the viewpoint of environmental protection. Yes, and for parts other than the foundation, we shall strive to protect the environment by using materials that can be completely recycled or recycled.

[0006] In advancing the development of the wall structure based on the above basic concept, the number of working steps can be significantly reduced by using the interior base material and the load bearing wall panel in combination, and
By omitting the pedestal materials such as studs and furring strips, it was considered to eliminate the processing work at the site and ensure uniform construction quality without being influenced by construction work by skilled engineers.

In the wall structure according to the prior art as described above, the peripheral portion of the inner wall panel is nailed and fixed to a pillar or a horizontal member which is a structural body, but the fixing method using a nail requires a labor for construction in the first place. At the same time, it is impossible to reuse the member, and it is impossible to meet the above-mentioned demand. Further, according to such a fixing mode, since the structural face material to be the load bearing wall is arranged on the indoor side with a large deviation from the axis of the column or the horizontal member which is the structural frame, a sufficient yield strength is achieved. There is a problem that it is difficult to demonstrate. Further, since the structural face material to be the load bearing wall is a thick plate material, attaching this to the inner surface of the structural body means that the effective indoor size is reduced by that thickness, which is wasteful. I must point out the problem.
