Description

[Detailed description of the invention] The present invention relates to a method for attaching a surface plate.

When attaching conventional surface plates, especially heavy ferrite tiles, etc., to walls, there are two methods: temporarily fixing them to the inner surface of the formwork with adhesive, or attaching elastic members such as rubber or resin to the inner surface of the formwork. The method used was to fit ferrite tiles into the four parts formed on this elastic member and temporarily fix them, then concrete was poured and the formwork was removed.

However, when adhesives are used, the supporting force is insufficient for mounting heavy panels, and there are problems with mounting accuracy.
In addition, post-processing work is required.

Furthermore, when elastic members were used, it was time consuming to remove several formworks after concrete was poured, and the supporting function of the elastic members was significantly deteriorated.

Therefore, the purpose of the present invention is to avoid using any adhesive to join the surface plate and concrete formwork, so that the formwork can be easily removed, the concrete formwork can be used repeatedly, and heavy We propose a surface plate mounting method that is suitable for face plate mounting and can reduce construction costs.

According to the present invention, a groove of a predetermined shape is formed in advance in the longitudinal direction approximately at the center of the surface plate.

On the concrete form side, a support is provided which projects from the outer surface of the concrete form to the inner side, and is removably fitted into the groove formed in the surface plate.

The support tool is fitted into the groove of the surface plate in advance, and the surface plate is temporarily attached to the inner surface of the concrete form by screwing the fixing tool.

Therefore, after fixing the concrete formwork, concrete was poured inside the formwork, and after the concrete had hardened, the supports fitted to the face plate were removed, the formwork was removed, and the face plate was attached to the concrete wall. It is something to attach.

The present invention will be explained below with reference to the embodiments shown in the drawings.

A so-called foot groove 2 having a cross-sectional shape extending in the longitudinal direction of the ferrite tile 1 serving as the surface plate is formed.

A support 4 is provided at a predetermined position of the concrete formwork 3 so as to protrude from the outer surface of the concrete formwork 3 to the inner surface thereof.

The support 4 has a threaded washer 5 attached to the outer surface of the concrete formwork 3, and a tightening bolt 6 that protrudes to the inside of the concrete formwork 3 is screwed into the threaded washer 5.
A plate spring 7 is inserted into a tightening bolt 6 on the side where the ferrite tile 1 is attached.

The leaf spring 7 is formed by protruding a pair of side sides 9, 9 from both ends of the base side 8 toward the ferrite tile 1 in a substantially U-shape, and both side sides 9.9 are formed inwardly. energized.

The base side 8 has a screw insertion hole into which a tightening bolt 6 is inserted, and a nut 10 is fixed at a predetermined position of the tightening bolt 6 between both sides 9.

The diameter of the opposite side of the nut 10 is larger than the length of the base side 8 by a predetermined value.
When the leaf spring 70 comes into contact with both sides 9, 9 and is pushed outward, the leaf spring 70 and both sides 9, 9 are strongly fitted into the grooves 2 of the ferrite tile 1, and the ferrite tile 1 is inserted into the concrete formwork 3. Can be fixed on the inside.

Further, when the tightening bolt 6 is advanced, the nut 10 also moves away from the base side 8, and both sides 9.9, which had been pressed outward, close inwardly due to the elastic force of the leaf spring itself, and the ferrite tile 1
can be removed from groove 2.

According to the installation method according to this embodiment, the concrete formwork 3
A tightening bolt 6 screwed into a threaded washer 5 provided on the plate spring 7 is moved forward to move the nut 10 away from the base 8, thereby suppressing the opening of both sides 9, 9 of the leaf spring 7 as much as possible.

In this way, a ferrite tile 1 is attached to the leaf spring 7 that suppresses the opening.
Align the grooves 2 to bring the inner surface of the formwork 3 and the surface of the ferrite tile 1 into close contact.

Then, the tightening bolt 6 is moved back, and the nut 10 is brought closer to the base side 8 of the leaf spring so as to come into contact with both sides 9, 9, and the sides 9, 9 of the leaf spring 70 are pushed outward.

In this way, both sides of the leaf spring s, s' + ferrite tile 1
The ferrite tile 1 is fixed to the formwork 3 by fitting into the groove 2 of the ferrite tile 1.

After this, concrete is poured, and after fixing the ferrite tile 1 with the concrete, turn the tightening bolt 6 to return the leaf spring sides 9 sufficiently inward, and the ferrite tile 1 is fixed.
The concrete formwork 3 is removed while pulling out the support 4 away from the groove 2 of the tile 1.

As shown in FIG. 2, it is possible to attach a plurality of supports 4 at predetermined positions depending on the weight or shape of the ferrite tile 1.

Furthermore, if the cross section of the ferrite tile 1 is formed into a dovetail shape as shown in FIG. 3, it will be more difficult to separate from concrete.

FIG. 4 shows a second embodiment of the invention.

According to this second embodiment, a T-shaped groove 2 is formed in the lateral direction of the ferrite tile 1.

On the other hand, a T-shaped support 4 corresponding to the groove 2 is attached to the formwork 3.

The support 4 is inserted into the groove 2 of the ferrite tile 1 and rotated 90 degrees to fix the ferrite tile 1 to the formwork 3, and then concrete is poured.

After pouring the concrete, the support 4 is rotated 90 degrees and removed from the groove 2 to separate the formwork 3 and the ferrite tile 1.

The panel mounting method according to the present invention can achieve the following effects through the above steps.

The formwork is easy to remove, post-processing and installation are easy, and the formwork can be used repeatedly, reducing construction costs.Especially when installing heavy panels, it has a large supporting capacity and is easy to position. The mounting accuracy is also high.
