[Bearing wall structure]
The load-bearing wall structure in one embodiment of the present invention is a load-bearing wall structure in a wooden shaft construction method, and includes a structural shaft member and a load-bearing wall panel, and the structural shaft member includes a fixing jig A, and The wall panel includes a fixing jig B that is coupled to the fixing jig A, and the load bearing wall panel is fixed to the structural shaft member by the coupling of the fixing jig A and the fixing jig B.

  Hereinafter, the bearing wall structure in one embodiment of the present invention will be described.

(Wooden frame construction method)
The wooden frame construction method is one of the manufacturing methods of wooden buildings, and is a method of assembling pillars and horizontal members in a rectangular frame shape and constructing a structure that is supported by a frame (strength bearing material, structural shaft). It is.

(Structural shaft material)
The structural shaft member includes a column member and a horizontal member as constituent members. The pillar material is a member that is erected in a vertical direction with respect to the ground. The horizontal member is a member that is installed in a horizontal direction with respect to the ground, such as a base, a beam, a girder, and a torsion.

  Basically, structural shafts are fixed to a base with pillars standing in a vertical direction and fixed to two or more fixed pillars in a horizontal direction. It is formed in a rectangular shape.

  As a method for assembling the structural shaft material, a conventional method can be adopted, and any method may be used as long as the assembled structural shaft material satisfies a predetermined strength. As a method for assembling the structural shaft material, for example, a method of fixing the members by processing each member may be used, or a method of fixing the members using hardware may be used.

(Bearing wall panel)
A load-bearing wall panel is attached to a wooden frame construction method to increase the strength of the wall of the building, and to improve the earthquake-resistant performance of the wooden building (resistance to horizontal loads such as earthquakes and wind). It is a member that improves the performance). The load-bearing wall panel may be a large wall system or a true wall system. The load-bearing wall panel is attached to the structural shaft after the upper building. By fixing the load-bearing wall panel to the structural shaft member, a load-bearing wall structure having a predetermined strength can be manufactured (constructed) without using braces.

  The load-bearing face material is a member that improves performance such as seismic performance of the wooden building, and is composed of, for example, a structural plywood, but the material is not particularly limited.

  The load-bearing wall panel may include a heat insulating material and / or a sound absorbing material (hereinafter referred to as “heat insulating / sound absorbing material”) in order to enhance the heat insulating effect and / or the sound absorbing effect. The heat insulating / sound absorbing material may be a member having a heat insulating effect and / or a sound absorbing effect, and examples thereof include foamed polystyrene and urethane, but are not particularly limited. The heat-insulating / sound-absorbing material may be attached to the load-bearing wall panel at the construction site. Since it does not need to be fixed, it can be attached at the time of manufacturing the load-bearing wall panel. That is, in the load-bearing wall structure in one embodiment of the present invention, before the load-bearing wall structure is manufactured (constructed) by fixing the load-bearing wall panel to the structural shaft, specifically, before the fixing step described later, Heat insulation and sound absorbing material can be attached to the load-bearing wall panel. Preferably, the heat insulating and sound absorbing material can be attached to the inner side surface and / or the outer side surface of the load bearing member of the load bearing wall panel before the fixing step described later. Here, the “inner side surface” of the load bearing surface material refers to the surface on the contact surface side with the frame material or the frame body. The “outer surface” of the load bearing material refers to a surface facing away from the inner surface. And when attaching a heat insulation and a sound absorption material to the inner surface of a load bearing surface material, it is more preferable to attach so that it may become flush with the frame of a load bearing wall panel or the structural shaft of a load bearing wall structure.

  Therefore, for example, when installing a heat-insulating / sound-absorbing material to a load-bearing wall panel when manufacturing a true-wall-type load-bearing wall panel, it is not necessary to secure a space for nailing inside the frame body. And thick insulation and sound absorbing material can be attached. Therefore, the heat insulating effect and / or the sound absorbing effect of the true wall type load-bearing wall panel can be improved. Further, by attaching a heat insulating / sound absorbing material during the production of the load-bearing wall panel, the working time at the construction site can be shortened, and the attachment state does not depend on the skill of the installer. The specific method for attaching the heat insulating / sound absorbing material to the load-bearing wall panel is not particularly limited.

(Fixing jig)
The fixing jig A provided in the structural shaft and the fixing jig B provided in the load-bearing wall panel are paired to form a fixing jig, and the load-bearing wall panel is fixed to the structural shaft by the fixing jig. The fixing jig constituted by the fixing jig A and the fixing jig B may be mechanically (physically) coupled or may be coupled by magnetic force. When the fixing jig is mechanically coupled, the convex jig may be on either side of the fixing jig A and the fixing jig B. Note that the fixing jig may have a configuration in which a plurality of convex jigs are coupled to one concave jig. Moreover, the fixing jig can also be used by combining a plurality of types of fixing jigs having different structures. In the present invention, “coupling” does not include the concept of “locking”.

  The fixing jig A and the fixing jig B are made of a material having mechanical strength capable of fixing the load-bearing wall panel to the structural shaft so as to obtain a load-bearing wall structure having a predetermined strength. There is no particular limitation. Examples of the material of the fixing jig include metals, resins, magnetic materials, and combinations thereof. Further, the fixing jig A and the fixing jig B are not particularly limited as long as they have a size capable of fixing the load-bearing wall panel to the structural shaft material. The weight of the fixing jig A and the fixing jig B is preferably lighter so that the burden on the installer is reduced.

  Further, when the fixing jig is configured to mechanically couple the convex jig and the concave jig, for example, the convex jig is inserted into the concave jig and fixed. It may be configured to be coupled to each other, or may be configured to be coupled by a combination of a latch and a box holder provided on a so-called door and door. That is, the fixing jig A and the fixing jig B may be configured to exhibit mechanical strength capable of fixing the load-bearing wall panel to the structural shaft material, and the specific shapes thereof are not particularly limited. .

  The number of fixing jigs included in the bearing wall structure is not particularly limited as long as the bearing wall panel can be fixed to the structural shaft so that the bearing wall structure having a predetermined strength can be obtained. Two or more are more preferable. That is, the bearing wall structure is more preferably provided with two or more sets of the fixing jig A and the fixing jig B, and more preferably four or more sets. The larger the number of fixing jigs, the better because the force applied to the load bearing wall structure is distributed to each fixing jig. In addition, when two or more fixing jigs are provided, it is preferable to attach them at regular intervals so that the force applied to the fixing portion is easily dispersed.

  The above-mentioned fixing jig A and the fixing jig B can be connected, for example, in consideration of the removal of the load-bearing wall panel at the time of renovation or the dismantling of the load-bearing wall structure at the time of rebuilding. It is more preferable that it can be released in consideration of reworking when it is fixed at an incorrect position or place. Thereby, remodeling and dismantling of a wooden building can be performed easily.

  According to one aspect of the present invention, by combining the fixing jig A and the fixing jig B, the load bearing wall panel can be fixed with stable strength. Also, a plurality of fixing jigs A and fixing jigs B can be coupled at the same time (simultaneously).

  Therefore, according to one aspect of the present invention, it is not necessary to nail and fix the bearing wall panel to the structural shaft material at the construction site, and since it can be easily constructed, the construction period can be shortened, It is possible to provide a load-bearing wall structure in a wooden frame construction method that can stably exhibit performance such as seismic performance as designed without depending on the skill of the installer. The load-bearing wall structure in one embodiment of the present invention can be used as a part of a member constituting a wooden building.

  Hereinafter, the manufacturing method of the load-bearing wall structure in one embodiment of the present invention will be described. However, the description overlapping with the content described in the above-mentioned bearing wall structure will be simplified or omitted.

<Jig attachment process>
The jig attaching step is a step of attaching the fixing jig A to the structural shaft and attaching the fixing jig B to the load-bearing wall panel before the fixing step. Specifically, taking the case where the fixing jig is mechanically (physically) coupled as an example, in the jig mounting step, a convex jig or a concave jig is attached to the structural shaft, and the load bearing wall panel is attached. Attach a pair of jigs to the structural shaft jig. That is, when the fixing jig A attached to the structural shaft is a convex jig, a concave jig is attached to the load bearing wall panel as the fixing jig B, and the fixing jig A attached to the structural shaft is a concave jig. In some cases, a convex jig is attached as a fixing jig B to the bearing wall panel.

  Moreover, it is preferable that a structural shaft material assembles members, after attaching the fixing jig A to each member.

The heat insulating / sound absorbing material attaching step is a step of attaching a heat insulating / sound absorbing material (heat insulating material and / or sound absorbing material) to the inner side surface and / or the outer side surface of the load bearing surface member of the load bearing wall panel before the fixing step. When the heat insulating / sound absorbing material is attached to the inner side surface of the load bearing surface member, it is more preferable to attach the heat insulating / sound absorbing material so as to be flush with the frame of the load bearing wall panel or the structural shaft member of the load bearing wall structure. By installing heat-insulating and sound-absorbing materials on the load-bearing wall panels at the assembly site of the load-bearing wall panels, it is possible to efficiently construct the load-bearing wall panels and achieve uniform heat-insulating and sound-absorbing effects regardless of the skill of the installer. Is obtained. Moreover, a construction period can be shortened by performing a heat insulation and sound-absorbing material attachment process before a fixing process.
