Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a connecting metal fitting for building materials used in the housing construction industry and the like, and more specifically, a base such as a foundation on a foundation, a girder or a purlin, and a floor or a floor. The present invention relates to a connecting metal fitting for a building material which can be attached to a building material such as a wall or a roof panel, and the two members can be easily connected and aligned with one touch, and can be securely fixed.

(Prior art) Conventionally, to a base 20 such as a foundation on a foundation, a girder or a purlin,
When a building material 21 such as a floor, a wall, or a roof panel is mounted and fixed, a connecting metal fitting 22 as shown in FIG. 6 is used. Attached with a nail plate 25 and the like,
The two members 20, 21 were connected and fixed by inserting the tension bolt 23 into a through hole 26 formed in the base 20, and then tightening a nut 27 at a lower portion thereof.

(Problem to be Solved by the Invention) In the above-mentioned connecting fitting, since the fastening of the two members is performed by bolts and nuts, the tightening work is troublesome. In many of these places, there is a case where the user forgets to attach or tighten the nut and causes inconvenience after construction.

In addition, this nut tightening is often performed by a worker at the base, for example, under the base,
Therefore, it is difficult to screw the nut and tighten the nut, and the operator is forced to take an unreasonable posture.

 And other various problems.

The present invention has been made to solve the above-described problems, and is attached to a base such as a foundation on a foundation, a girder, or a purlin, and a building material such as a floor, a wall, or a roof panel to join and align these two members. It is an object of the present invention to provide a connection fitting for a building material that can be easily and easily performed with one touch and that can be securely fixed.

(Means for Solving the Problems) Means of the present invention for achieving the above-mentioned object are as follows: a first mounting piece attached to one side surface of a building material by a fastening member; On the contact surface side, a plurality of locking claws that bite into the base surface and are fixedly protruded at a predetermined pitch, and a locking rod corresponding to a first mounting piece mounted on the building material,
A second attachment piece attached to one side surface of the base by a fastening member, an insertion fitting part provided on the second attachment piece to guide the insertion of the locking rod and press the locking claw against the base surface; In the construction of a connecting member for building material provided with

(Operation) The present invention configured as described above has the following operation.

First, the first mounting piece is attached to one side surface of the building material by a fastening member, and the second mounting piece is fixed to the base at a predetermined mounting position corresponding to the vertical position of the locking rod by the fastening member. Keep it.

Then, with the building material corresponding to the upper part of the base, the locking rod attached to the building material is inserted into the insertion portion of the base, and the building material is pressed down until these two members are closely adhered. As the back of the locking claw moves toward the inside, that is, the lower part while being pressed by the inner surface of the insertion portion, and when the building material comes into close contact with the base portion, the lateral movement is hindered by the side wall of the insertion portion. In addition, since some of the large number of locking claws corresponding to the base surface of the locking rod bite into the base surface to hinder the vertical movement of the locking rod, the building material is desired on the base. The two members are firmly connected to each other by being placed at an accurate position where the locking claw bites into the base surface.

(Embodiment) Next, an embodiment of the connection bracket for building materials according to the present invention will be described with reference to the drawings.

In FIGS. 1 to 5, A is a connecting bracket, which is formed by punching out a press using a rigid metal plate. In the case shown in FIGS. Used to connect the base 1 to building materials 2 such as floors and wall panels,
In the case shown in FIG. 5, the base 1 such as a purlin is used for coupling with a building material 2 such as a roof panel, and the above-mentioned connecting fitting A is composed of a first mounting piece 3 and a second mounting piece. And four.

The first mounting piece 3 is formed in a flat shape such that one side surface is in close contact with the surface of the building material 2, and is fixed to the building material 2 at a plurality of locations by fastening members 5 such as nails, screws or screw nails. A through hole 6 is formed.

In the middle of the lower edge of the first mounting piece 3, a locking rod 7 having a predetermined length is extended in a T shape and hangs down.
As shown in FIG. 2, the locking rod 7 is bent in a V-shaped cross section, and a large number of serrated locking claws 8 are provided at both front edges thereof at a predetermined pitch.

Although the locking claw 8 is formed integrally with the locking rod 7, although not shown, a support having a large number of locking claws 8 protruding is attached to the locking rod 7. It may be connected by welding or the like.

Further, the second mounting rod 4 is formed in a flat shape such that one side surface is in close contact with the base 1 surface in the same manner as the first mounting piece 3, and a plurality of stoppers such as nails, screws or screw nails are provided. Through hole 9 fixed to base 1 by attachment member 5
Has been drilled.

And on the other side, the locking rod 7
An insertion portion 10 bulged to have substantially the same size as the width of the locking claw 8, preferably slightly smaller, is provided, and when the locking rod 7 is inserted, the insertion portion 10 The rear surface of the locking claw 8, that is, the V-shaped top is pressed by the wall surface 10a, and the locking claw 8 is pressed against the base 1 surface side, and the locking claw 8 is cut into the base 1 so that the locking claw 8 is moved. The two members of the base 1 and the building material 2 are connected by biting the surface.

When the insertion portion 10 is formed in a tapered shape that opens upward, it serves as a guide when the locking rod 7 is inserted, thereby facilitating insertion.
The movement of the locking rod 7 in the lateral direction is prevented by b and 10b.

(Effects of the Invention) As described above, the connecting member for a building material of the present invention simply inserts the locking rod of the first mounting piece into the insertion portion of the second mounting piece and pushes the same, and the two members of the base and the building material are used. Can be connected and positioned at the same time, and the workability of the attachment is dramatically improved, and the work can be performed with one touch, so that the labor burden of the worker is reduced.

Also, since a large number of locking claws protrude at a predetermined pitch, once they bite into the base surface, there is no detachment thereafter, and moreover, the back surface of the locking claw is always pressed by the inner wall surface of the insertion portion, There is no bite return of the locking rod, and the reliability of the connection of the two members is high. This connection is made by making close contact with the base of the building material, so that a large number of bolts and nuts are used as in the conventional bolt-nut type. Even if there is a connection point, there is no forgetting to conclude,
The quality of home building can be improved.

 And so on.
