Description

[Detailed description of the invention] The present invention relates to a joint fitting for a concrete receiving plate that fixes the concrete receiving plate in the correct butt state against the perforated wood without simply nailing the plate.Please refer to the attached drawings. The details are as follows.

Concrete receiving plate 2 (normally 12mm) fixed to sanding board 1
Similar channel receiving frames 3 are placed above and below a channel receiving frame 3 bent in a U-shape in cross section with a sandwiching interval equal to the thickness of a plywood board (often made of plywood board of about do.

A main plate 4 having a length equal to the side width of the sander 1 is provided in series at the middle side of this intermediate channel receiving frame 3.

In the drawing, the channel support frame 3 is protruded in the same plane as the back surface of the channel support frame 3, but the same effect can be obtained by protruding it slightly offset and supporting both edges of the left and right concrete support plates 2 with a single crosspiece. be.

A locking plate 5 is connected to the tip of the main plate 4 at right angles.

The locking plate 5 is provided with a locking hole 6 with a hangnail on the inside.

Figure 4 shows the state of use, and the joint fitting used for the outer end of the farthest panel plate 2 that is not joined cuts the oppositely directed channel receiving frames 3 arranged vertically as shown in Figure 3. It is desirable to use one with a similar structure.

To form a conventional concrete wall, two concrete receiving plates (veneer plates) are placed side by side at a predetermined interval and concrete is poured between them to form a concrete wall. Care must be taken to avoid defection.

Various types of this device have been developed, and generally, bolts commonly called separators are passed through, and nuts are screwed on both ends to prevent them from separating beyond a predetermined distance. Therefore, if the concrete receiving plate is not placed near the abutting portion of the concrete receiving plate, and the abutting edge of the concrete receiving plate separates outward, a flat wall surface will not be formed.

For this reason, in the past, a block was always erected at the joint, and the edge of the concrete receiving plate was nailed to this block.

This nailing process is extremely troublesome as many nails are driven in, and each nail must be removed each time the tile is dismantled.

The present invention solves this problem, and when the present product is inserted into the block from the side, the length of the main plate 4 is made equal to the side width of the block 1, so that the side of the channel receiving frame 3 and the locking plate are made equal. 5 and sandwich the sandwich 1, and the channel receiving frame 3 is fixed to the front side of the sandwich.

Therefore, when the edge of the concrete receiving plate 2 is inserted into the channel receiving frame 3, the edge of the concrete receiving plate 2 is fixed to the sanding board 1.

In this case, the channel receiving frames 3 are arranged vertically in opposite directions, so when the edge of the adjacent concrete receiving plate 2 is inserted into the channel receiving frame 3 facing the opposite direction, the concrete receiving plate 2 is pressed in the correct butt state. It will be fixed to the front of 1.

The end edges of the concrete receiving plates 2 can be fixed to this block 1 as long as the joints of the adjacent concrete receiving plates 2 do not shift, so the oppositely facing channel receiving frames with continuous back walls should be fixed. Only by fitting the edges of adjacent concrete receiving plates 2 to 3, it is possible to reliably prevent the butt joints from sliding when concrete is poured.

In other words, there is no need to drive nails into the full-heat slab, and simply inserting the proposed product into the slab 1 and inserting the edge of the concrete receiving plate 2 into the channel receiving frame 3 is sufficient to achieve the desired purpose. This has practical effects such as being able to achieve the following.
