Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a tile formwork pre-installation method, and more particularly to a tile formwork pre-installation method using a tile mounting member.

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 above-mentioned 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 above-mentioned gap to bond the tiles directly to the concrete surface. After curing, the outer formwork and the 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]

The conventionally used tile formwork tip construction method will be explained using the construction of tread joints as an example.

As shown in FIGS. 11 to 15, the tile attachment member 1 includes a long flat substrate 2 extending along the direction of the through joint A, and a tile mounting member 1 formed on the upper surface of the substrate over the entire length of the substrate 2. It consists of a protruding strip 3 having a protruding locking edge 4 on the top for fixing the tile T, and is usually manufactured by extrusion molding an elastic material 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. 11, it is necessary to construct a joint in the direction perpendicular to the through joint A, that is, to construct the divided joint B. The tile T and the tile joint members 6 are alternately fitted between the tile mounting members 1 arranged in parallel, using the tile joint members 6 made of an elastic material such as rubber or foamed plastic.
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 seeks to solve]

The first problem with the above construction method is that when fitting the tile T between the tile mounting members 1, the protruding locking edges 4 of the protruding strips 3 must be raised with a spatula, etc. The problem is that it is not easy to attach the tiles T to the formwork 5. The second problem is that the tile is fitted under strong pressure, so if the locking edge 4 made of an elastic material deforms, the upper surface of the protrusion 3 is a flat surface that forms the bottom of the joint. The bottom of the joint is no longer smooth.

[Means for solving problems]

The first problem mentioned above is that the long flat substrate and
A protrusion is formed on the upper surface of the substrate over the entire length of the substrate and has a tile locking edge on the upper longitudinal edge, and a longitudinal fitting groove is formed on the upper surface of the protrusion. Tile mounting members made of an elastic material such as rubber or plastic are formed in advance, and the tile mounting members are fixed in parallel on a flat formwork with a predetermined interval between them. After fitting the tiles into the groove, press-fit a long bar having a cross section substantially complementary to the groove, and use the formwork in which the tiles are arranged and fixed in this way as an outer formwork, Achieved by a tile formwork pre-installation method using tile mounting members, characterized in that concrete is poured between the outer formwork and the inner formwork spaced apart to form a tile wall. .

The second problem mentioned above is that the device includes a long flat substrate and a protruding strip formed on the upper surface of the substrate over the entire length thereof and having a tile-locking edge on the upper longitudinal edge. Further, a tile mounting member made of an elastic material such as rubber or plastic is formed in advance on the upper surface of the protrusion, and has a longitudinal fitting groove formed therein, and the tile mounting member is placed on a flat formwork. After fixing them in parallel with each other at a predetermined interval and fitting the tile between the tile mounting members, the lower part has a hanging part with a cross section that is substantially complementary to the fitting groove, and the upper part has the above-mentioned protrusion part. A long T having a thin flat plate with a width approximately equal to the upper surface width of
The shapes are press-fitted into the fitting grooves, and the formwork in which the tiles are arranged and fixed in this way is used as the outer formwork, and concrete is poured between the outer formwork and the inner formwork spaced apart. This is achieved by a tile formwork pre-installation method using a tile mounting member characterized in that the tile wall is formed using a tile wall.

〔Example〕

Hereinafter, the construction method of the present invention will be explained according to the examples shown in FIGS. 1 to 10. Note that members having the same functions as those in the prior art are designated with the same reference numerals.

Tile mounting member 1 used in the construction method of the present invention
Similar to the conventional tile mounting member, the board 2 includes a long flat board 2, and a tile locking edge 4 formed on the upper surface of the board 2 along the entire length thereof, and a tile locking edge 4 on the upper longitudinal edge.
It is integrally formed of an elastic material such as rubber or plastic. However, in the first aspect of the present invention, as shown in FIGS. 1 and 2, a fitting groove 7 extending in the longitudinal direction is formed on the upper surface of the protrusion 3, and the fitting groove 7 has a cross section that is substantially complementary to the fitting groove 7. A long bar 8 made of a hard material is prepared.
Incidentally, the cross section of the fitting groove 7 and the elongated bar 8 in the embodiment shown in FIGS. 1 and 2 is wedge-shaped.

Figures 3 and 4 show a modified example in which the above-mentioned fitting groove 7 and long bar 8 have a dovetail groove shape in cross section and a corresponding dovetail tenon shape. becomes certain. Further, although the engagement between the fitting groove and the elongated bar shown in FIGS. 1 and 2 is somewhat uncertain, press-fitting is extremely easy. Therefore, engagement can be supplemented by temporary fixing using an adhesive locally.

The tile mounting members 1 thus formed are fixed in parallel on a flat formwork 5 at predetermined intervals.
Since the external dimensions of the tiles T vary, a tile T of approximate dimensions is selected, and the tile mounting member 1 is set in accordance with the dimensions. A tile T is fitted between the tile mounting members using a spatula (not shown), and a conventional tile joint member 6 (FIG. 14) is fitted into the tile joints between the tiles. In the above-mentioned fitting of the tile, since the protrusion 3 has the fitting groove 7, the locking edge 4 bends softly during fitting, so that the fitting operation is not difficult and is extremely easy. Next, by press-fitting the elongated member 8 into the fitting groove 7, the tile T is fixed to the tile attachment member 1.

As shown in Figures 5 to 7, the formwork 5 in which the tiles T are arranged and fixed as described above is used as an outer formwork (formwork placed outdoors during concrete pouring), and the inner formwork on the indoor side It is erected and fixed with an appropriate interval between it and the frame 9. Reinforcing bars 10 are arranged between the two formworks, and then concrete 11 is poured. After curing, the inner and outer formworks 5 and 9 are demolded, and the outer formwork 5 is separated from the tile T with the tile attachment member 1 and the divided joint member 6 attached, and the remaining tile T is completely attached to the concrete 11. Adheres to form tile walls.

As mentioned at the beginning, in the tile formwork pre-installation method, as a general rule, joint filling is not performed after construction, so the concrete joints 12 are left as they are. Therefore, it is desirable to make the concrete joints 12 smooth from the viewpoint of improving the appearance.

The second invention of the present invention shown in FIGS. 8 to 10 takes the above into consideration, and differs from the first invention in that, instead of the long bar 8, a fitting groove 7 is provided at the bottom, and the cross section is substantially complementary. A hard elongated T-shaped member 15 is used, which has a hanging portion 13 and a thin flat plate 14 having a width approximately equal to the upper surface width of the protrusion portion 3 at the upper portion. Using such a long T-shaped member 15 not only facilitates the work of fitting the tile T in the same way as in the first invention, but also creates a smooth thin wall on the concrete surface when the formwork 5 is demolded after curing the concrete. A beautiful bottom joint formed by the flat plate 14 can be obtained. The cross section of the fitting groove 7 and the hanging part 13 in the embodiment of FIG. 8 is wedge-shaped, and
The cross sections of the fitting groove 7 and the hanging portion 13 shown in the figure are formed into a round groove shape and a corresponding dovetail and tenon shape.

〔Effect of the invention〕

As mentioned above, in the past, it was difficult to fit the tile between the tile mounting members even if a tool such as a spatula was used, but according to the first invention, by providing a fitting groove on the upper surface of the protrusion, It is possible to increase the deflection of the locking edge during fitting, and in some cases it becomes possible to fit the tile without using tools. Furthermore, by press-fitting a long bar into the fitting groove after fitting, the tile can be securely fixed. Furthermore, according to the second invention, since there is a smooth plane made of a thin flat plate on the upper surface of the protrusion, a tile wall constructed using this method has the advantage that a joint floor with an excellent appearance can be obtained. .
