Abstract

PROBLEM TO BE SOLVED: To improve strength by positioning structural face bar at the side surface of a framework material, bringing a plate material into contact with the surface of a nailing margin at the structural face bar peripheral-edge part with the nailing margins of adjacent structural face bars being strided over, and jointing them with nails or the like. SOLUTION: Structural face bars 6, 6' are disposed at the side surface of a framework part consisting of continuous footing 1, a sill 2, a pipe column 3 and a girth 4, and plate materials 5, 5' are brought into contact with them, with the nailing space of the structural face bars 6, 6' being strided over. Nails 7 penetrating through the plate material 5 and the structural face bars 6, 6' is driven from the above side of the plate material 5 which is brought into contact with the structural face bars 6, 6', and they are jointed to the framework part. When the building receives earthquake force, and shear stress acted on a wall structure surface, the end parts of the structural face bars 6, 6' fixed next to the tube 3 are pulled in the opposite direction to each other, and the nail of the joint part receives double shear. It is thus possible to attain a bearing wall with excellent vibration-proofing by action of the double face shear.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a surface bearing wall for improving the earthquake resistance of a building such as a house.

[0002]

2. Description of the Related Art Conventionally, as a method of constructing a load-bearing wall in a wooden building, there are a method using a pier, a method using a streak, a method using a structural surface material, a method using both of them, and the like. A load-bearing wall constructed by nailing structural members to pillars, studs, foundations, beams, beams, and other horizontal members,
It is called a "bearing wall" and its details are described in the "Wooden House Construction Common Specifications" issued by the Japan Housing Finance Spread Association. As described in this commentary, the nail is driven directly over the structural facing.

[0003]

However, the conventional method of forming a load-bearing wall according to the prior art has a problem that the nailing strength is inferior to the shear strength of the structural face material. As a method of increasing the nail joint strength, it is conceivable to increase the number of nails and reduce the load per nail. However, in addition to the fact that this method requires a lot of work,
There are new problems such as a narrow interval between the nails and cracking of the frame.

The problem to be solved by the present invention is that a nail 1
What kind of measures should be taken in order to obtain sufficient and stable strength of the face bearing wall without increasing the number of nails by increasing the joining strength per piece? .

[0005]

In order to solve such a problem, according to the present invention, a structural face material is located on a side face of a frame member, and a surface of a nailing margin at a peripheral portion of the structural face material is provided. Then, a plate material is applied across the nailing allowance of the adjacent structural face material, and the respective structural face materials are joined to the frame member by nails, screws, etc., penetrating the plate material. We propose a structural material bearing wall.

[0006]

[Function] In the case of the above-mentioned structural material bearing wall, when the surface material bearing wall receives a horizontal load due to an earthquake or a typhoon, and a shearing force acts on the joint surface between the structural member and the frame member, A two-sided shearing force acts on the nail joining the parts. The allowable joint strength of nails against double shear is approximately twice as large as the allowable strength of nails against single shear when using the method of hitting nails directly from above on the structural panel according to the prior art. . As described above, by increasing the joining strength of the nail, the shear strength of the structural face material is maximized, and thus the strength of the face strength wall is sufficiently and stably obtained.

Embodiments will be described with reference to the drawings.
FIG. 1 is an explanatory view showing the appearance of an embodiment of a face material bearing wall structure according to the present invention. 1 is a cloth foundation. Structural surface materials 6, 6 'are located on the side surfaces of the frame portion composed of the base 2, the tube column 3, and the body difference 4, and the structural surface materials 6, 6'
And a nail 7 penetrating the plate 5 and the structural face members 6 and 6 ′ from above the plate 5.

FIG. 2 is a cross-sectional view taken along the line AA in FIG. 1, and illustrates double shearing at the nail joint. Reference numeral 3 denotes a pipe column, 6, 6 'are structural face materials, 5 is a plate material, 7 is a nail, and P and P' represent directions of loads acting on the structural face materials 6, 6 'as images. It was done. P,
The orientation of P 'varies in practice, but usually, P and P' are reversed when resisting forces of particular importance, such as earthquakes and typhoons. When the building receives seismic force and shear stress is applied to the wall surface, the facing ends of the structural panels 6 and 6 ′ that are fixed adjacent to the pipe column 3 are such that if one is upward, the other is downward. In opposite directions. Because P and P 'work in opposite directions, the nail at this joint will be subjected to double shear and will exhibit twice the joint strength as compared to the conventional single shear. .

FIG. 3 is a sectional view showing another embodiment of the structure of the face material bearing wall according to the present invention.
6 'is a structural face material and 5 is a plate material. The plate material 5 may be a wood-based material such as a rough plate or a plywood processed into a belt shape, but a steel plate of about 1 mm is used here. Structural surface material 6,
A heat insulating material 8 is provided on the outside of 6 ′, and an exterior material 10 is further nailed via a body edge 9.

[0010]

Since the present invention is configured as described above, it has the following effects.

Since a two-sided shearing force acts on the nail joint between the frame member and the structural face material, the nail joint strength is remarkably improved, and the bearing wall has extremely excellent earthquake resistance.
