[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint for connecting a wall material provided at an edge with a reinforcing frame formed of a so-called lip channel having an inward flange on an open surface. is there.

[0002]

2. Description of the Related Art For example, a wall frame of a unit bath has a reinforcing frame formed of a lightweight channel steel having a special cross-sectional shape fixed to a peripheral edge portion thereof. A special joint fitting is fixed in advance, and a reinforcing frame of a wall material to be retrofitted into the clip formed in the joint fitting is pushed into the groove of the lightweight channel steel so as to elastically engage the clip with the groove. The rear wall is connected to the rear wall. According to this, the assembling work from the back side of the wall material is not required, and the nails and screws are not exposed on the surface.

[0003]

However, in the case of this prior art, the workability is low because a drill or a tool is required to attach the joint fitting to the reinforcing frame, and spring steel must be used for the joint fitting. In addition, the reinforcing steel bars are relatively expensive because they require a special cross-sectional shape.

[0004] The present invention has been devised in order to solve such disadvantages of the prior art, and its main objects are as follows.
It is an object of the present invention to provide an improved wall material connecting joint capable of improving workability and reducing cost.

[0005]

SUMMARY OF THE INVENTION According to the present invention, there is provided a joint for connecting a wall member provided with a channel-shaped reinforcing frame having an inward flange on an open surface. A substantially U-shaped cross section, an engagement groove is formed outside each edge portion, a guide surface is continuously provided in one engagement groove, and a retaining claw is continuously provided in the other engagement groove. A first portion, a second portion in which a resilient engaging claw having an arrowhead cross section protrudes from the center and a resilient pressing piece protrudes on one side, and both the first and second portions. This is achieved by forming a base with a synthetic resin.

[0006]

After engaging one side of the inward flange of the channel steel of the front end wall with the engaging groove having the retaining claw, pushing the other side along the guide surface and engaging with the engaging groove. As a result, the first portion is connected to the channel steel of the front wall. Next, the open face of the channel of the retrofit wall is pushed into the resilient engaging claw of the barbed cross section, whereby the channel of the retrofit wall is joined to the second portion. Then, the channel steel connected to the second portion is pressed by the resilient pressing piece, and is less likely to be displaced in the pull-out direction, and is prevented from falling off. Therefore, it is possible to interconnect the reinforcing frame and the joint with a so-called one-touch operation without using a tool, and in addition, the lip channel steel can be used.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The construction of the present invention will be described in detail below based on specific embodiments shown in the accompanying drawings.

FIGS. 1 to 4 show a wall material connecting joint constructed according to the present invention. This joint is formed by injection molding of a synthetic resin material, and includes two clip portions connected at a base. This joint includes a joint 1 for connecting a plurality of wall materials to each other on the same plane by abutting each other, and a joint 2 for connecting the wall materials at right angles to each other, as shown in FIGS. 1 and 2. Has two clips 4 on the base 3
Reference numeral 5 denotes a butt connection 1 provided adjacent to each other, and the one shown in FIGS. 3 and 4 has two clip parts 4.5 provided on a W-shaped base 6 in directions orthogonal to each other. 2 for orthogonal connection. These two types of joints 1
2 is different from each other in the shape of the base portions 3 and 6, but the clip portions 4 and 5 are common.

The first clip portion 4 of the two clip portions 4 and 5 has a substantially U-shaped cross section, and engagement grooves 7a and 7b are formed on the outer sides of both end edges, respectively. An inclined guide surface 8 is formed on one of the outermost edges, and an outward locking claw 9 is formed on the other outermost edge. The second clip portion 5 includes a resilient engaging claw 10 having a barbed cross section protruding at the center, and a resilient pressing piece 11 protruding adjacent to one side of the resilient engaging claw 10. Are formed.

Next, how to use the joint will be described.

[0011] The wall material 12 connected using this joint
a · 12b is a so-called lip channel steel reinforcing frame 14a · 1 having a channel shape provided with inward flanges 13a · 13b on the open surface.
Reference numeral 4b is a standard-sized plate material attached around the back surface. First, one side 13a of the inward flange of the reinforcing frame 14a of the wall material 12a to be attached is attached to the retaining claw 9 of the first clip portion 4.
After engaging with the engaging groove 7b having a groove, the other side 13b of the inward flange is pushed along the guide surface 8. Then, the open end side of the first clip portion 4 having the U-shaped cross section bends inward, and the other side 13b of the inward flange engages with the engagement groove 7b. As a result, the first clip portion 4 is connected to the reinforcing frame 14a of the leading wall 12a.

Next, a reinforcing frame 14b of a wall material 12b to be retrofitted
Is pushed into the resilient engaging claw 10 having an arrowhead cross section, the reinforcing frame 14b of the rear wall 12b is connected to the second clip portion 5. And the reinforcing frame 1 connected to the second clip portion 5
4b is prevented from dropping because the displacement in the pullout direction is regulated by the pressing force of the resilient pressing piece 11.

When wall materials are sequentially attached in this manner and a molding material or the like is embedded in the gap between the corners, displacement of the adjacent wall materials in the direction of coming out of the engaging grooves 7a and 7b or the engaging claws 10 is prevented. Since they block each other, the wall material is firmly fixed.

If each clip part and the base part are manufactured separately from each other and are configured to be integrally connected by, for example, a dovetail groove connection or the like, it is possible to further diversify according to the standard of the reinforcing frame and the part to be used. It is possible to respond.

[0015]

As described above, according to the present invention, it is possible to interconnect the reinforcing frame and the joint with a so-called one-touch operation without using a tool, so that the assembling workability can be greatly improved. In addition, since the lip grooved steel can be used, the construction cost, including the cost of the reinforcing frame material, can be significantly reduced as compared with the related art.
