Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a joint for connecting a wall member provided at an edge portion with a reinforcing frame formed of so-called lip channel steel having an inward flange on an open surface.

[0002]

[Prior art]

 For example, the wall material of the unit bath has a reinforcing frame made of lightweight channel steel with a special cross section fixed to the peripheral edge, and a dedicated joint metal fitting is attached to the reinforcing frame of the wall material to be attached in advance using tapping screws. It is fixed in advance and the reinforcing frame of the wall material to be attached later is pushed into the clip part formed on this joint fitting and the clip part is elastically engaged with the groove of the lightweight channel steel to attach it to the front wall. The rear wall is connected. According to this, it is not necessary to assemble from the back side of the wall material, and moreover, nails and screws are not exposed on the surface.

[0003]

[Problems to be solved by the device]

 However, in the case of this conventional technology, the workability is low because a drill or tool is required to attach the joint metal fittings to the reinforcing frame, and spring steel must be used for the joint metal fittings. It is relatively expensive because it requires a large cross-sectional shape.

The present invention has been devised to eliminate such disadvantages of the prior art, and its main purpose is to improve workability and reduce cost. To provide a wall material joint.

[0005]

[Means for Solving the Problems]

 For this purpose, according to the present invention, a joint for connecting wall members provided with a reinforcing frame of a channel member having an inward flange on an open surface has a substantially U-shaped cross section. Engagement grooves are formed on the outer sides of the respective edge portions, a guide surface is continuously provided to one engagement groove, and a retaining pawl is provided continuously to the other engagement groove, and an arrowhead shape. The elastic engagement claw of the cross section is provided at the center and the elastic pressing piece is provided at the one side, and the second portion is formed, and the base portion connecting both the first and second portions is formed. This is achieved by using resin molding.

[0006]

[Action]

 After engaging one side of the inward flange of the channel steel of the front wall with the engagement groove with the retaining claw, push the other side along the guide surface to engage with the engagement groove. The first portion joins the channel steel of the wall. Then, the open surface of the grooved steel of the rear wall is pushed into the resilient engagement claw of arrow-shaped cross section, and the grooved steel of the rear wall is joined to the second portion. Then, the channel steel joined to the second portion is pressed by the elastic pressing piece and becomes difficult to be displaced in the pulling-out direction, and the dropping is prevented. Therefore, it becomes possible to connect the reinforcing frame and the joint with a so-called one-touch operation without using a tool, and in addition, it becomes possible to use the lip groove type steel.

【Example】

 Hereinafter, the structure of the present invention will be described in detail with reference to specific embodiments shown in the accompanying drawings.

1 to 4 show a wall material connection joint constructed according to the present invention. This joint is formed by injection molding of a synthetic resin material, and has two clip portions connected by a base portion. There are two types of joints, one for connecting a plurality of wall members to each other on the same plane, and the other for connecting them so as to be orthogonal to each other, as shown in FIGS. 1 and 2. Is a butt connection 1 in which two clip parts 4 and 5 are provided adjacent to each other on an I-shaped base 3, and the one shown in FIGS. 3 and 4 is a W-shaped base 6. The two clip portions 4 and 5 are for orthogonal connection 2 provided in directions orthogonal to each other. These two types of joints 1 and 2 are different in the shape of the bases 3 and 6 but have the same clip portions 4 and 5.

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

Next, the usage of this joint will be described.

The wall members 12a and 12b to be connected by using this joint are attached to the periphery of the rear surface by reinforcing frames 14a and 14b of so-called lip channel steel having a groove shape having inward flanges 13a and 13b on the open surface. It is a standard size plate material. First, one side 13a of the inward flange of the reinforcing frame 14a of the wall material 12a to be attached in advance is engaged with the engaging groove 7b having the retaining tab 9 of the first clip portion 4, and then is attached to the guide surface 8. And push the other side 13b of the inward flange. Then, the open end side of the first clip portion 4 having a 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 coupled to the reinforcing frame 14a of the front wall 12a.

Next, if the open surface of the reinforcing frame 14 b of the wall material 12 b to be retrofitted is pushed into the resilient engagement claw 10 having an arrowhead-shaped cross section, the reinforcing frame 14 b of the rear wall 12 b is joined to the second clip portion 5. . Further, the reinforcing frame 14b coupled to the second clip portion 5 is restricted from being displaced in the pull-out direction by the pressing force of the elastic pressing piece 11, so that the reinforcing frame 14b is prevented from coming off.

When the wall materials are sequentially attached in this manner and the molding material or the like is embedded in the gaps at the corners, the wall materials adjacent to each other are pushed out in the engaging grooves 7 a and 7 b or the engaging claws 10. Since the displacements are prevented from each other, the wall material is firmly fixed.

If the respective clip portions and the base portion are manufactured separately from each other and are configured to be integrally coupled by, for example, dovetail groove coupling, it is possible to further diversify according to the standard of the reinforcing frame and the use part. Will be available.

[0015]

[Effect of device]

 As described above, according to the present invention, since the reinforcing frame and the joint can be interconnected by a so-called one-touch without using a tool, the assembly workability can be greatly improved. In addition to this, since the lip groove type steel can be used, the construction cost including the cost of the reinforcing frame material can be significantly reduced compared to the conventional construction cost.
