Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel which is fitted into a rectangular opening formed by a base or a beam and a pillar of a wooden frame building to form an outer wall, and which is provided with a wooden brace. It relates to outer wall panels.

[0002]

2. Description of the Related Art In a wooden frame building, a wooden base is placed on a foundation, columns are set up and beams are passed over to form a frame, and a square opening formed by the base or beams and columns is braced. , Further arrange studs and piers appropriately, attach the outer wall material to the outdoor surface, attach the inner wall material to the indoor surface,
Forming a wall. In order to give sufficient seismic performance to wooden framed structures, it is necessary to have more than a certain proportion of walls with braces, and the triangle formed by the foundation or beams and columns and the braces is the building in the event of an earthquake or typhoon. It resists the lateral force acting on the building and prevents the building from collapsing.

In the wooden frame building having such a structure, after the frame is formed, the work of assembling the braces, studs and piers,
Further, since the work of attaching the outer wall material and the inner wall material is all performed on site, there is a problem that the work is easily affected by lack of manpower and weather, and the construction period becomes very long.

In order to solve this problem, each member forming a wall is assembled into a panel-shaped unit in a factory, and the assembled panel is transported to the site to be assembled to save labor and shorten the construction period. Are disclosed in Registered Utility Model Publication Nos. 3027256 and 3046731. Registered Utility Model Bulletin No. 3027256
The one described in the publication is a type to be fitted into a rectangular opening formed by a base or a beam and a pillar, and the one described in the registered utility model publication No. 3046731 is a brace, a stud, a pier, etc. Is a unit with pillars, and a panel is assembled on the base or beam and the beam is placed on the upper edge of the panel to form a shaft and a wall at the same time.

In wooden structures, preservatives and termites have been applied to the frameworks, braces, studs, etc. near the ground mainly to prevent damage from termites. Since these chemicals were applied after assembling each member, the chemicals were not sufficiently applied to the mortises, pillars, braces, small edges of the studs, etc. of the base, and the antiseptic and anti-termite effects were not achieved. Was enough.

[0006]

The members such as bases, beams, columns, braces, studs, etc., which are the constituent members of the wooden building, are the same as those used in the conventional method of assembling them on site. Cutting, tenon processing, and notch processing are performed, and high processing accuracy is obtained. However, the wood often undergoes a slight deviation due to drying or moisture absorption after being processed, and the deviation is apt to appear as a bending in the axial direction. Therefore, the rectangular opening formed by the base or the beam and the pillar assembled at the site may have a bend in the side in the direction of narrowing the opening.
A panel that fits in the opening of a frame assembled on site must be manufactured so that its external dimensions fit snugly into the opening of the frame. You can't get crowded. Therefore, the panel is made slightly smaller so that the panel can be fitted even if the pillar or beam is slightly bent. Then, metal reinforcing plates are attached to the two corners of the panel, which are the both ends of the brace, and nailed to the side surfaces of the column or beam to integrate the column or beam with the panel.

However, in such a structure, the braces installed in the corner panel do not come into close contact with the intersections between the base or the beams and the pillars, and the foundations or the beams and the connections between the pillars and the braces are connected via the reinforcing plate. It is not preferable because it is only performed. Also, even if the length of the brace is cut accurately in the factory, the vertical and horizontal edges of the panel will be present between the tip of the brace and the intersection of the frame,
The thickness accuracy of the edging material and the assembly accuracy of the corners influence the accuracy of the brace length, which causes a reduction in the contact accuracy between the tip of the brace and the intersection of the framework, which is not preferable.

According to the structure in which the brace and the pillar are unitized in the factory (the structure as described in the above registered utility model No. 3046731), the tip of the brace and the crossing portion of the frame can be brought into close contact with each other. However, there is a problem that the panel structure becomes complicated and heavy, making it difficult to manufacture the panel, and mounting the panel on site is also difficult and time-consuming. In particular, if you do not assemble correctly so as not to make a mistake in the assembly order, the problem that the last one will not be assembled will occur. Further, since the work procedure at the site is significantly different from that of the conventional structure, there is a drawback that it takes a lot of time for the site worker to learn and manage the work, and errors are likely to occur.

An object of the present invention is to solve the above-mentioned problems of the conventional outer wall panel for a wooden framed building, and the adhesion between the framed frame and the braces is good, and therefore the earthquake resistance is excellent. An object of the invention is to obtain an outer wall panel that can obtain a wall structure, can be easily manufactured in a factory and assembled on site, and can shorten the construction period and save labor.
