Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a tile mounting member used in a tile formwork advance construction method.

Recently, the tile formwork pre-installation method has been attracting attention from the viewpoint of streamlining the tile construction method in construction, preventing peeling, and resolving the problem of lack of skilled workers.

In the tile formwork pre-installation method, tiles with their soles facing upward are arranged and fixed in advance between the tile mounting members (joint bars) installed on the formwork in the factory, and the tiles are placed with the tile side facing inwards at the site. The formwork is arranged upright as an outer formwork, and is held with a predetermined gap between it and the inner formwork, and then concrete is poured into the gap to bond the tiles directly to the concrete surface, After curing, the outer formwork and inner formwork are demolded to form a tile wall.

A method in which an elastic material is used for the joint bars described above to facilitate the transfer of tiles from the outer formwork to the concrete surface is called the elastic joint bar method. When using the tile formwork pre-installation method, it is economical because the outer formwork can be reused several times. As a general rule, the concrete surface is used as a joint without any subsequent filling.

[Conventional technology]

A conventionally used tile mounting member will be explained.

As shown in FIGS. 3 to 7, the tile mounting member 1 includes a long flat substrate 2 extending along the direction of the through joint A, and a top surface of the substrate 2 formed over the entire length of the substrate 2. It consists of a protruding strip part 3 having a protruding locking edge part 4 for fixing the tile T on the upper part thereof,
It is usually manufactured by extruding elastic materials such as rubber or plastic. The above-described tile mounting members 1 are fixed in parallel on a formwork 5 made of plywood or the like using fastening members such as screws, nails, and staples.

Since the above-mentioned tile mounting member 1 constitutes only the through joint A, in order to constitute the horse-tread joint as shown in FIG.
That is, in order to constitute the divided joint B, the divided joint members 6 made of an elastic material such as rubber or foamed plastic are used, and the tiles T and the divided joint members 6 are alternately fitted between the tile mounting members 1 arranged in parallel. go. Tapers are formed on both edges of the back surface of the tile T, and both edges of the tile T are fitted between the tile mounting members 1 using a spatula (not shown) such as a spatula or a metal spatula.

[Problem that the invention attempts to solve]

Such a tile mounting member 1 has the following drawbacks.

(a) In order to fit the tile T between the locking edges 4, it is necessary to use a specially shaped tile with tapered edges on both sides of the back side.

(b) Tools such as a spatula are required to fit tiles, and the fitting process requires skill.

(c) There is usually variation in tile dimensions. Projection part 3
If the tiles are larger than the spacing between them, the upper surface of the protrusion 3 will be deformed as shown in FIG. As mentioned above, in the tile form pre-installation method, joint filling is not performed afterwards, so the joint bottom of the tile wall constructed using this tile mounting member becomes defective and the finished appearance deteriorates.

The purpose of this invention is that there is no need for a spatula or the like to fit tiles, and that ordinary tiles can be used.
Moreover, it is an object of the present invention to provide a tile mounting member that does not cause deformation of the joint bottom.

[Means for solving problems]

The above purpose is to provide a rigid rubber or plastic elongated sheet having a flat substrate and a T-shaped cross-sectional protrusion extending over the entire length of the substrate on the top of the substrate. The upper horizontal side of the T-shaped cross section of the protrusion has a joint forming part with a width slightly narrower than the joint width, and the vertical side has a supporting part of the joint forming part. In addition, protrusions made of elastic rubber or plastic are formed on both sides of the supporting part in the longitudinal direction and protrude in the width direction from the joint forming part, and the protrusions are hollow and have a protruding shape. This is achieved by a tile mounting member used in the tile formwork advance construction method, which has a space provided on the substrate side of the section.

〔Example〕

As shown in FIGS. 1 and 2, the main body of the tile mounting member according to the present invention is a long member made of rigid rubber or plastic whose cross section is roughly shaped, and is attached to a flat substrate 7. A protrusion 8 having a T-shaped cross section is formed over the entire length of the substrate 7. Further, the relatively thin upper horizontal side portion of the T-shaped cross section of the protrusion 8 is a joint forming portion 9, and the width of the joint forming portion 9 is formed to be slightly narrower than the width of the joint to be formed. Further, the vertical side portions of the T-shaped cross section constitute the support portion 10 of the joint forming portion 9 and are relatively thick.

On both sides of the support part 10, protrusions 11 having hollow parts 12 made of elastic rubber or plastic extending in the longitudinal direction are formed with a space 14 provided between them and the substrate 7. If the tile mounting member is made of plastic, it is convenient to manufacture it by co-extrusion of the rigid tile mounting member body and the resilient projection.

The tile attachment members formed as described above are arranged on the formwork 5 at predetermined intervals and fixed using an appropriate fastening member or adhesive. A normal tile 13 is fitted between the tile mounting members arranged in this way (a normal tile is a tile T shown in Fig. 4).
(This refers to those that do not have a tapered part on the back surface, such as.)
In this case, the elastic protrusion 11 is compressed by the fitting of the tile 13, and the repulsive force causes the tile 13 to be compressed.
is held between the tile mounting members to prevent the tile from falling. Since no tools such as a spatula are required, the fitting operation can be carried out easily and quickly.

In addition, since the width of the joint forming portion 9 of the protrusion 8 is formed to be slightly narrower than the width of the joint to be formed, even if there is variation in the tile dimensions, the tile 13 will fit into the joint forming portion 9.
There is no direct contact with. Furthermore, since the protrusion 11 is hollow, it has a wide range in which it can absorb dimensional errors in the tile, and strain caused when the tile is fitted can be released into the space 14 provided between the protrusion 11 and the substrate 7. Therefore, the upper surface of the joint forming part 9 is always kept horizontal as shown in the figure, and no joint bottom failure occurs when concrete is poured. The support portion 10 made of a rigid material also contributes to keeping the joint forming portion 9 horizontal. The shape of the protrusion 11 must be considered so that it does not deform and protrude toward the joint (upward) when the tile 13 is fitted.

[Effects of the invention] Since the present invention is configured as described above, there is no need for a special type of tile or a tool such as a spatula for fitting, and the rigid joint forming part is not deformed due to variations in tile size. Since there is no cement paste, a good finished appearance and well-aligned joints can be obtained, and since the elastic protrusions hold the tiles tightly, there is no leakage of cement paste and a beautiful tile wall can be obtained.
