Regarding.

Conventionally, when attaching a panel material to a concrete wall surface, it has been carried out to make the panel material flat by a method such as interposing sleepers to match the unevenness caused by the wall surface.

However, the work of arranging sleepers and the like according to the edges of the concrete wall surface is complicated and requires a great deal of work effort, so improvements have been desired.

In addition, when panel materials are used as waste forms, there is no simple means to adjust the unevenness of the panel materials, so when using finishing materials as waste forms, a large number of end pieces are placed to prevent the occurrence of unevenness. It was necessary to take measures such as setting up

The present invention was made with the aim of solving these conventional problems, and is a mounting bracket consisting of an anchor member embedded in a concrete wall, a head member attached to a panel material, and a connecting member connecting these two members. The connecting member or head member is attached in advance to the panel material that will become the waste form, and after concrete is poured, the connecting member or head member is rotated from the surface side of the panel material, and the screw connection of the connecting part is used to attach the concrete of the panel material. By adjusting the distance from the wall surface, it is possible to correct unevenness of the panel material due to bumps. The present invention will be explained in detail below with reference to examples.

As the distance between the anchor member 4 and the head member 5 increases, the panel material 1 and the heat insulating material 2 move in the direction of arrow B.
displacement in the direction. Therefore, the unevenness of the panel material 1 as a whole can be corrected by rotating the connecting member 6 to a position where the unevenness of the panel material 1 is corrected by adjusting the necessary mounting fittings 7.

In this way, the mounting bracket 7 according to the present invention can be used to attach the panel material 1 used as a waste form and the heat insulating material 2 to the concrete wall 3, and to easily adjust the unevenness of the panel material 1 due to the bulging of the concrete wall 3. It has the advantage of being able to be corrected.

Figure 2 is a cross-sectional view of another embodiment of the present invention, in which figure a is a cross-sectional view when concrete is placed, and figure b is a cross-sectional view after correction of unevenness. Using foamed polystyrene foam or the like with good adhesion, the anchor member 4 and the connecting member 6 are screwed together, and the connecting member 6 and the head member 5 are connected to the head 6a.
are connected by being held between the stepped portion 5d and the perforated inner nut 9, and the hole 8 of the inner nut 9
The structure is such that the connecting member 6 can be rotated through the connecting member 6. In this example, the panel material 1 and the heat insulating material 2 are not bonded together, and by rotating the connecting member 6 in the direction of arrow A, only the panel material 1 is displaced in the direction of arrow B.

FIG. 3 shows a modification of the embodiment shown in FIG. 2, in which first and second head members 51 and 5 are integrally fastened together with a head member 5 holding a panel material 1 and screwed together.
2, 5e is the first head member 5
This is the driver hole for turning 1. This has the advantage that it can be applied to a thin panel material 1 as well.

FIG. 4 shows yet another modification in which the head member 5 is constructed with an eyelet. This has the advantage that the head member 5 can be made at a low cost, and the head member 5 can be attached to the panel material 1 in a single crimping operation, which reduces the labor involved.

FIG. 5 is a sectional view of another embodiment, in which the anchor member 4
The connecting member 6 and the connecting member 6 are integrated into one threaded rod, and the head member 5 is made of a plastic molded product, and the first and second head members 5
1 and 52 have legs 10a and 10b that fit into each other, respectively, as shown in FIGS. The female thread 5a is formed by fastening the plastic material to the plastic material and screwing in a threaded rod 46 using the plasticity of the plastic material.
In this example, the panel material 1 can be displaced by rotating the head member 5 through the driver hole 5e. This example has the advantage of being simple and inexpensive.

FIG. 7 is a cross-sectional view of another embodiment, in which a first head member 51 is made of plastic material in the shape of a nut with a seated head, and a second head member 52 is constructed of a washer with a claw. The first head member 51 is inserted into the panel material 1, and the second head member 52 is press-fitted into the neck portion 5f of the first head member 51 and is locked by its claw 52a.

This has the advantage that the head member 5 can be assembled easily and quickly.

8a to 8d are cross-sectional views for explaining the structure and method of use of another embodiment, in which the head member 5 has a configuration in which the second head member 52 of the embodiment of FIG. 7 is removed. It is. This mounting bracket 7 is first made by overlapping the panel material 1 and the heat insulating material 2 as shown in Fig. 8a, making the pilot hole of the panel material a little thicker, and holding it to the heat insulating material 2 by the neck portion 5f. Attach it in the form. Figure b is a sectional view when concrete is poured, and the anchor member 4 is fixed to the concrete wall 3. Next, the head member 5 is rotated and screwed back to the extent that the unevenness can be corrected. At this time, since the head member 5 is only loosely fitted into the panel material 1, as the uneven and recessed portion of the head member 5 is unscrewed, the panel material 1 will be fixed as shown in Figure c.
The unevenness is corrected by the elasticity of. Next, a viscous adhesive 12 is injected through the injection hole 11 formed in the panel material 1, as shown in FIG. 4D, and when it hardens, the panel material 1 is fixed.

Note that when the head member 5 is unscrewed, the unevenness may not be corrected by the elasticity of the panel material 1 alone due to friction caused by the eccentricity of the prepared hole in the panel material 1. In this case, unscrew the head member 5 a little more, inject the adhesive 12 from the injection hole 11,
The panel material 1 is pushed out by the pressure of the injected adhesive 12, and then the head member 5 is screwed into a predetermined position to correct the unevenness. In any case, when injecting the adhesive 12, it is necessary to use an injection method that avoids applying pressure to the panel material 1 during injection, such as by screwing the nozzle of an injection machine into the injection hole 11.

This configuration has the advantage that the attachment fittings 7 can be easily attached, and the attachment fittings 7 can be attached even after the waste mold frame is assembled.

In the above embodiments, the panel material 1 and the heat insulating material 2 are stacked to form a frame, but it goes without saying that the present invention can also be applied to a case where the heat insulating material 2 is not provided.

In addition, the mounting fittings according to the present invention include both the anchor member and the head member, which are made of metal or plastic molded products.
It goes without saying that it can also be formed from a composite of metal and plastic.

As explained in detail above, the present invention includes an anchor member fixed to a concrete wall, a head member attached to a panel material, and a connecting member that connects these two members and attaches the panel material to the concrete wall surface. At least one of the connecting members and the anchor member and head member is connected by a threaded connection, and one of the connecting members or the head member making up this screwed connection is made of the panel material. It is configured to be rotatable from the surface side, and has the effect that the panel material used as a waste form can be directly attached to the concrete wall surface, and it can be easily corrected by adjustment work performed from the surface side of the panel material using a fillet.
