Description

[Detailed Description of the Invention] [Purpose of the Invention] Industrial Application Field The present invention relates to a joint bar for attaching tiles to a formwork before pouring concrete or mortar.

Conventional technology As disclosed in Japanese Utility Model Application No. 59-51950, as a joint rod for attaching tiles to a formwork, elastic members are used on one or both sides of the tile contact side of a crosspiece adjusted to the joint width. By providing a joint bar, gluing the joint bar to the formwork, and fitting the tile between them,
There was a method for attaching tiles easily and reliably.

Problems that the invention aims to solve However, the conventional joint rods as mentioned above
Since the tiles are held solely by the repulsive force of the elastic members, there is a risk that the tiles may fall off if shock or vibration is applied when assembling the return formwork, etc., and there is also a risk of the tiles falling off. There were problems such as mortar paste leaking from between the tiles and staining the joint sides of the tiles, requiring a great deal of effort to remove.

This invention was devised to solve the problems of the conventional joint bars mentioned above, and its purpose is not only to make it easy and reliable to attach to the formwork, but also to make it easier to finish the tile wall surface. To provide a joint rod for attaching tiles first that is simple and can reduce costs in a comprehensive manner.

[Structure of the invention] Means for solving the problem The joint rod for attaching tiles according to the invention includes an elastic member provided along at least one side surface of a cross-shaped hard member on the tile contact side, and a shape of the hard member. An adhesive layer is provided on at least one of the frame adhesion side and the tile contact side of the frame or the tile contact side of the elastic member, and the width of the elastic member is slightly narrower than the width of the hard member to form a stepped portion. It is characterized by:

Embodiment Next, an embodiment of the present invention will be described with reference to the drawings.

In FIG. 1, a joint bar 1 basically consists of a hard member 2 and an elastic member 3. As shown in FIG. The hard member 2 may be made of a single material or a composite material such as wood, plywood, metal, solid material such as plastic or synthetic rubber, hollow material, or foam material.

In addition, as the elastic member 3, a foamed material or a hollow material such as a highly elastic plastic such as foamed ether type urethane or synthetic rubber or a hollow material is used to absorb dimensional errors and installation errors of tiles, etc. It is designed to prevent installed tiles from falling or falling off.

An adhesive layer 4 made of a release paper adhesive is provided on the back side of the hard member 2 on the side to which the mold is adhered, and the release paper is peeled off and adhered to the mold.

Further, an adhesive layer 4 is attached to the tile contacting side of the upper surface of the hard member 2 and the tile contacting side of the lower surface of the elastic member 2.

The adhesive layer 4 may be coated with an adhesive, and the adhesive layer 4 on the top surface of the hard member 2 on the tile contact side may be omitted.

Furthermore, as is clear from FIG. 1, the width of the elastic member 3 is made slightly narrower than the width of the hard member 2, and a stepped portion 5 of approximately 1 mm is formed between the two members. It absorbs the dimensional errors and attachment errors of 2 and 3, and prevents the elastic member 3 deformed when fitting the tile from protruding from the surface of the hard member 2, thereby preventing it from digging into the poured concrete. .

Next, a method for constructing a tile wall surface using the joint rod 1 of the above embodiment will be explained.

First, as shown in FIG. 2A, in line with the tile layout markings on the formwork 6, while peeling off the release paper on the adhesive 4 side, apply the joint bar 1 in a tight motion to securely adhere the tile.

Next, as shown in FIG. 2B, press the top surface of the tile T against the elastic member 3 of the upper joint bar 1, and while crushing this, insert the lower side of the tile T, and When set to the first hard member 2, the second
As shown in Figure C, the tile T is firmly fixed by the adhesive layer 4 while being elastically sandwiched between the upper and lower joint bars 1,1.

Next, as shown in Fig. 2D, a vertical joint bar 1' is set on the side of the tile T between the upper and lower joint bars 1, 1, and while being sandwiched between it and the tile T fitted next to it, Adjust the position of tile T.

After setting the tiles T sequentially downward from the top in this way, as shown in Figure 3, the reinforcing bars 7
Assemble and attach separator 8. The return formwork 6' is carried out with care to suppress impact and vibration as much as possible so as not to apply direct impact to the formwork 6 on which the tiles T are attached.

Once the formwork 6, 6' has been assembled in the manner described above, concrete is poured and after hardening, the formwork is dismantled.

[Effects of the invention] (1) Since an elastic member is provided on the underside of the hard member, tiles can be set in accurate positions using the hard member glued to match the land markings.
Not only can the tile be easily fitted while pressing and crushing the tile against the elastic member, but also tiles of various sizes can be reliably attached in advance.

(2) Since an adhesive layer is attached to the back side of the hard member, the joint bar can be adhered to the formwork extremely easily and reliably.

(3) Since the adhesive material is attached to at least one of the hard member and the elastic member on the tile contact side, the joint bar and the tile are firmly joined, there is no risk of the tile falling off, and the adhesion between them is There is no problem with post-processing due to leakage of mortar paste, etc.

(4) Since the width of the elastic member is made slightly narrower than the width of the hard member to form a step, it is possible to absorb dimensional errors and attachment errors between the hard member and the elastic member, and to absorb the elastic material that is deformed when the tile is inserted. By preventing the member from protruding beyond the surface of the hard member, it is possible to prevent the member from digging into the poured concrete.
