Description

[Detailed description of the invention] This invention presets tiles or tile units on the finished surface of a formwork panel for precast concrete plates or on the inner surface of an outer frame panel for pouring concrete at a construction site, and The present invention relates to a tile holding device used in the so-called tile-first installation method, in which tiles are pasted at the same time as installation.

Conventionally, in the tile tipping method, a lattice-shaped rubber joint cell or rubber joint frame has been used to absorb and retain dimensional errors in tiles. However, in this case, within the elastic limit of the rubber joint cell or rubber joint frame, the dimensional error of the tile can be absorbed and the tile can be held, but if the dimensional error exceeds the elastic limit, the gap between the tile and the joint cell or joint frame is A gap may appear between the tiles, making it impossible to hold the tiles, or it may become difficult to fit the tiles into the joint cells or joint frames, resulting in poor workability.

This invention is intended to solve the above-mentioned problems, and even if there is a dimensional error in the tiles, the tiles can be held securely on the formwork panel, and the tiling work can be done efficiently. It is an object of the present invention to provide a tile holding device that can be used.

In this specification, the inside-outside relationship is based on Figure 2, and the direction toward the tile from the formwork panel in the figure, that is, the right direction in the figure, is referred to as inward, and the opposite direction is referred to as outer. .

The tile holding device according to this invention includes a plurality of strip-shaped core materials that are attached in parallel at required intervals on the inner surface of a formwork panel, and a plurality of long base materials made of an elastic material that have attachment grooves that are attached to the core materials. This is a tile holding device for the tile tip construction method, which consists of a plurality of short joint materials made of an elastic material arranged so as to sandwich the tile between adjacent long joint materials.

Examples of this invention will be described below.

In FIGS. 1 to 3, the finished surface of a formwork panel 1 for producing a precast concrete board is inked in a desired pattern in advance. According to the markings, a plurality of belt-shaped core members 2 made of plywood or synthetic resin boards having a required thickness are arranged horizontally at required intervals and attached with screws 3 or staples.

Each of the core members 2 is provided with a long joint filler 4 made of soft rubber. The long joint base material 4 has an installation groove 4a with an outward opening and a U-shaped cross section, a long joint protrusion 4b provided at the center of its width in an inwardly protruding manner and having a required protrusion height, and a protrusion of the long joint groove 4a. It consists of side protrusions 4c for hanging tiles provided on both sides of the tip.
The mounting groove 4a is fitted into the core material 2, and the nail 5 is fitted into the mounting groove 4a.
Alternatively, it is attached to the core material 2 with staples.

A plurality of rectangular tiles T are arranged astride adjacent long joint materials 4 with their back surfaces facing inside. The inner edges of both sides of the tile T are beveled in an inclined manner, or
Or stepped. The tile T is held by each of the long joint protrusions 4b, and is latched to the side protrusions 4c at the inclined surfaces or steps at the inner ends on both sides.

Between the plurality of tiles T, a short joint material 6 made of soft rubber is arranged across the adjacent long joint protrusions 4b. The short joint filling material 6 has a length equal to the gap between the adjacent long joint protrusions 4b, a plate thickness equal to the protrusion height of the protrusions 4b, and a required protrusion height at the center of the length. Outer protrusion 6 for maintaining the distance between the
It is equipped with b.

In this state, concrete is poured inside the tile T, and after curing, it is removed from the mold, the tile holding device of this invention is removed from the tile installation surface, and if necessary, the joints are filled, as shown in Figure 1. The tiled wall is finished as shown.

The order in which the tiles and joint fillers are attached is not limited, but usually the short joint fillers 6 and tiles T are alternately placed on adjacent long joint fillers 4.

The above embodiment is for a case where the formwork panel 1 is installed vertically, and a case where the long joint material 4 is arranged horizontally on the formwork panel 1, but the tile holding device according to this invention is Of course, this is not limited to this case.

If you prepare several kinds of joint materials with different widths and/or heights, and select the appropriate joint materials according to the dimensions of the tile T, you can create a tiled surface that looks good without disturbing the joints. . In this case, if the joint materials are color-coded for identification by width and/or height, the selection of joint materials can be made easier and the workability of tile installation is greatly improved.

The tile holding device invented by this invention is configured as described above, so even if there is a dimensional error in the tile, the tile can be held securely in the formwork panel, and the tile will not fall off during concrete pouring. There is no fear at all. Therefore, there is no need to use glue to hold the tiles, and workability is very good. Furthermore, since the long joint base material made of an elastic material is attached to the formwork panel via the core material, the long joint base material can be attached to the required position accurately and quickly.
