Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint fitting for simultaneously joining a bracing to a horizontal member and a column member standing on the horizontal member, at least on the horizontal member side and the pillar member side. The present invention relates to a box-shaped bracing box having an upright side.

[0002]

2. Description of the Related Art A conventional bracing box used in the state shown in FIG. 1 has the following structure.

As shown in FIG. 4, a horizontal bridge member abutting plate portion 4B which abuts the upper surface of the horizontal bridge member 1 at an edge portion of the horizontal bridge member lower side of the bracing plate member 4A which abuts the braces 3. Is installed in a bent state,
A column material contact plate portion 4C that abuts the side surface of the column material 2 is provided in a bent continuous state at the side edge portion of the column material on the lateral side of the bracing contact plate portion 4A. 4B and the locking claws 7 provided on the column member abutting plate portion 4C are driven and locked to the horizontal frame member 1 and the column member 2, and provided on the horizontal frame member abutting plate portion 4B and the column member abutting plate portion 4C. Brace contact plates fixed by fixing nails or screws through the fixing holes 6 to fix the bracing box 4 to the corners of the horizontal member 1 and the column member 2, and fixing the box 4 upright. The portion 4A is brought into contact with the braces 3, and the fastening holes 5 provided in the bracing plate portion 4A are selected to fix the braces 3 at a predetermined angle by fastening the bolts 11 and driving nails. It is a thing.

[0004]

However, in the conventional bracing box, as shown in FIG. 5, the plate material is formed by bending in order to enhance the mass productivity and reduce the cost. , The bracing contact plate portion 4A is formed by connecting the standing pieces to the two sides of the square bottom plate, which are simply the bracing contact plate portion 4A, and bending the rising pieces on each side at right angles. A horizontal member abutting plate portion 4B and a column member abutting plate portion 4C are bent and formed on the two sides respectively.

Therefore, the horizontal member abutting plate portion 4B and the pillar member abutting plate portion 4C are merely raised, and therefore the horizontal member abutting plate portion 4B and the pillar member abutting plate portion 4C. Are not directly connected to each other. When a load is applied to the column member 2 and the braces 3 with respect to the horizontal member 1 when used, the strength facing them is extremely weak. In this respect, the bearing strength (fastening / fixing strength) is inferior.

Further, in order to supplement this strength, it is conceivable to weld and join the adjacent portions of the horizontal member abutting plate portion 4B and the column member abutting plate portion 4C, but this makes the welding process troublesome. Therefore, the cost is significantly increased and the mass productivity is deteriorated.

It is an object of the present invention to provide a bracing box which has a structure which can be formed by bending a plate material as in the past, but which is excellent in the practicality of the structure in which the bearing strength is remarkably increased. .

And the overlapping plate 4D is integrally provided, and the connecting portion 8 between the horizontal member abutting plate portion 4B and the column member abutting plate portion 4C is bent at a substantially right angle to form a horizontal member abutting plate portion 4B. A bracing box characterized in that, when the column member abutting plate portion 4C is formed, the respective superposed plates 4D are superposed to form a superposed brace abutting plate portion 4A. It is related.

[0010]

For example, it is formed in a plate material as shown in FIG. 3, and the folding edges of the horizontal member abutting plate portion 4B and the overlapping plate 4D and the column member abutting plate portion 4C and the overlapping plate 4D which are continuously arranged are respectively formed. When the connecting portion 8 between the horizontal member abutting plate portion 4B and the column member abutting plate portion 4C, which are bent at a right angle and connected to each other, are bent at a right angle, the overlapping plates 4D overlap with each other to make a striation contact. The plate portion 4A is formed.

Although not shown in FIG. 3, the brace contact plate 4A is attached to the brace contact plate 4A.
A fastening hole 5 penetrating the two overlapping plates 4D constituting A is formed, and fastening bolts 11, nails, and fixing screws are driven into the fastening holes 5, so that the overlapping plate 4D is displaced.
