Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint material for connecting wire rods such as joists and rafters that form a framework for floors and roofs, and particularly to in-plane proof stress of wall panels and floor panels that form unit buildings. It is a suitable one to be used.

2. Description of the Related Art Generally, a wall type construction method is known in which structural frame members are attached to each frame of a floor and a wall to form a floor panel and a wall panel, and the floor panel and the wall panel are assembled into a box-shaped structure. (Framework construction method house construction common specifications: issued by the Housing Finance Association). According to this wall type construction method, external force is evenly supported on the entire floor and the entire wall, as compared with the case of the frame construction method consisting of columns and beams, and it is possible to obtain high structural strength. ..

A unit building system is known as a system for increasing the industrial production rate of buildings. When the above wall-type construction method is applied to a unit building, a single building is composed of a plurality of room units in which a floor panel is erected on a floor panel (JP-A-57-19440) and each room unit. It will be divided into roof units that will be joined to the upper part of each unit, and after each unit is produced in the factory, these units will be transported to the construction site and installed on the foundation prepared in advance.

By the way, in the wall-type construction method, in order to secure or reinforce the in-plane proof stress of various panels, the joint members are used to form the wire rods (hereinafter, referred to as main wire rods) constituting the panel frame, for example, floor joists Are being combined.

[0005]

However, in the above-mentioned conventional wall-type construction method, as shown in FIG. 7, a single material having the same size (cross-sectional area) as floor joists 1, 1 or less is used. It is used as the joint material 2, and the both mouths of the joint material 2 (the end faces of the transverse portion at right angles to the fiber direction of the wood) are applied to the two sides of the two adjacent floor joists 1, 1 to face each other. Since the floor joists 1 and 1 were joined by nailing the corresponding floor joist side surface, the following problems occurred.

That is, as shown in FIG. 8 (a), if the joint members 2, 2, ... Are attached in a line orthogonal to the floor joists 1, 1 ,. ) Can be secured. However, when this joining structure is adopted, the floor joist 1 and the joint material 2 on one side can be fixed by flat striking of a nail (CN90), but the floor joist 1 and the joint material 2 on the other side. With regard to the above, it was necessary to fix both of them by diagonally striking nails (CN75) 3, 3, ... From the side surface of the joint material 2 to the other side of the floor joist. Therefore, when a local load is applied to the joint materials 2, 2, ..., Cracks often occur along the fiber direction of the joint materials 2, 2, ... Or an unpleasant nail squeaking noise is generated. It was

In order to prevent cracks in the joint members 2, 2, ... And squeaking noises of the nails, instead of arranging the joint members 2, 2 ,. Then, the floor joists 1, 1, ... May be sequentially shifted and attached. However, according to this joining method, the generation of cracking and squeaking noise is avoided, but effective surface rigidity (in-plane proof stress) cannot be secured.

The present invention has been made in view of the above circumstances, and provides a joint material which can prevent cracking and squeaking noise due to local load and can effectively secure the in-plane proof stress of the panel. The purpose is to

[0009]

In order to solve the above-mentioned problems, the joint material according to claim 1 is a method for connecting main wire rods such as joists and rafters which form a framework such as a floor and a roof,
A joint material for ensuring the in-plane proof stress of the frame, a pair of fixing plates that are fixed by matching the respective side surfaces of two adjacent main wires facing each other, and the fixing plates facing each other. And an H-shaped connecting plate.

[0010]

According to the structure of the present invention, since the respective surfaces of the pair of fixing plates can be applied to the respective side surfaces of the two main wire rods facing each other, the joint material can be made the main wire rods by flat hammering. Can be attached and fixed to. Therefore, it is possible to prevent the joint material from cracking and the squeak noise of the nails to be generated, and since the joint materials can be arranged in a line, it is possible to effectively secure the in-plane proof stress of various panels.
