Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a load-bearing panel which is mainly mounted in a wooden frame of a house and bears a horizontal force, and an architectural frame structure using the load-bearing panel. Things.

[Conventional technology and issues]

Conventionally, in wooden structures, horizontal forces such as earthquakes are often dealt with by struts and wall arrangements.

However, conventional wood-structured buildings are not only limited by the strength of the timber, but also by the struts and walls as horizontal load-bearing members, which limit the degree of freedom in the design of openings and spaces. However, it takes a lot of time, and it requires a craftsman with special skills, which makes mass production difficult.

The present invention provides a new horizontal bearing member that can be prefabricated, and by incorporating this into a structural frame, enables mass production, increases the degree of freedom in design, and improves the rationalization and quality of construction. It is intended.

The present invention relates to a load-bearing panel for building, which is a load-bearing panel to be attached to a wooden frame structure, wherein a central vertical member 2 and a pair of vertical frame members 12 on both sides thereof are connected between upper and lower horizontal frame members 13, Each of the lattice members 3 is joined between the vertical member 2 and the vertical frame members 12 on both sides, and each lattice member 3 bends the steel pipe in a wavy shape to flatten the abutting portion thereof and to the central vertical member 2. The contact portions of the lattice members 3 are bolted in common via respective steel plate fixing plates 8, and the contact portions of the lattice members 3 are connected to the vertical frame members 12 on both sides through the steel plate fixing plates 8. It is characterized in that it is individually bolted, and a face material 11 is attached to one side.

In the building frame structure of the present invention, the unit of the load-bearing panel is arranged in a frame formed by upper and lower horizontal members and left and right vertical members constituting a wooden building frame.

Strength panel gives great strength as horizontal strength member,
By disposing a plurality of such load-bearing panels having a large wall magnification in the frame, an opening such as a doorway or a window can be widened, and the degree of freedom in design increases.

〔The invention's effect〕

In the load-bearing panel of the present invention, a central vertical member and a pair of vertical frame members on both sides thereof are connected between upper and lower horizontal frame members, and a lattice member is joined between the central vertical member and both vertical frame members. ,
In addition, it is made into a unit by attaching a face material to one side, so that it is possible to provide a lightweight and strong horizontal strength member.

The lattice member bends the steel pipe in a wavy shape to flatten the abutment portion, and the abutment portion of the lattice member is joined to the central longitudinal member by a common bolt via a steel plate fixing plate. The abutment of the lattice member on the frame material is individually bolted via a steel plate fixing plate, and the bent part that receives the pressing force due to the presence of the steel plate is made of wood. It prevents the strength from being reduced by digging into the member, and the steel plate fixing plate secures the joint by bolting to one.
By converting from point support to multi-point support, rotation of the joining bolt due to shear force acting from the lattice member can be prevented,
A stable joining structure can be obtained.

Regarding the joining of the lattice member and the face material, it is possible to attach it to the factory, and the accuracy can be improved, so that a light and strong joint can be achieved. In addition, by attaching the face materials in advance, the time and labor for on-site work can be saved, and the panel strength can be improved. In addition, when installing the panel frame material to the frame, if a clearance is provided in consideration of the construction accuracy of the frame at the site construction, errors can be absorbed, and force transmission will be nailed with packing material sandwiched Alternatively, the face material may be larger and pasted and nailed to the frame at the protruding portion (in this case, the packing material is also unnecessary).

When the lattice member is symmetrical with respect to the central vertical member, a large force is not generated in the central vertical member when a horizontal force is applied, so that the vertical member can have a small cross section. In addition, if the lattice member is arranged in a closed shape with respect to the horizontal member as shown in FIG. 1, the number of attachment portions of the lattice member is small, and the transmission of force is rational.

In the frame structure of the present invention, by using the load-bearing panel having the above-described effects, the workability can be improved, and the opening can be widened as compared with the bracing and the general wall structure. Also has a high degree of freedom, allowing for a free space design.
