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. 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 reliably held on the formwork panel, and the tiling work can be carried out 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 the present invention includes a plurality of strip-shaped core members that are attached in parallel at required intervals on the inner surface of a formwork panel, and a mounting groove that is attached to the core members so as to create a small gap between them and the formwork panel. A plurality of short joint materials made of elastic material are arranged so as to sandwich the tiles between adjacent long joint materials and have through holes in the inside and outside directions, and It has a protruding rod part that passes inward, and has a plurality of holding members whose both ends are fitted into the small gaps, and a fitting hole that tightly fits into the penetrating end of the protruding rod part, and the tile. This is a tile holding device for the tile tipping method, which consists of a tile hanging piece that hangs on the back side, and a tile attachment device.

Examples of the present 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 consists of a mounting groove 4a with an outward opening and a U-shaped cross section, and a long joint protrusion 4b with a required protrusion height provided at the center of the width of the groove 4a in an inwardly projecting manner. . And the mounting groove 4a
are fitted into the core material 2 and attached to the core material 2 by nails 5 or staples so as to create a small gap A between this and the formwork panel 1.

A plurality of rectangular tiles T are arranged astride adjacent long joint materials 4 with their back surfaces facing inward, and are held by each long joint protrusion 4b.

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 a. In addition, a through hole 7 is formed in the center of the length of the short joint filler 6 in the inner and outer directions.

On the outside of each of the short joint fillers 6, there are disposed horizontally T-shaped holding members 8 for holding them on the formwork panel 1, respectively. The member 8 is made of synthetic resin,
It consists of a flat plate part 8a and a protruding rod part 8b provided at the center of its length in a manner to project inward. Then, the protruding rod portion 8b is passed through the through hole 7 of the short joint material 6, and the flat plate portion 8
Both ends of a are fitted into a small gap A formed between the attachment groove 4a of the long joint material 4 and the formwork panel 1. In this way, the short joint material 6 is held by the holding member 8.
is held on the formwork panel 1.

Small flat tile hanging pieces 9 made of synthetic resin are arranged inside each of the short joint fillers 6. The locking piece 9 has a fitting hole 10 in the center of its length,
The penetrating end portion of the protruding rod portion 8b passing through the through hole 7 of the short joint filler 6 is tightly fitted into the fitting hole 10. The tile hanging pieces 9 are hung on the back surfaces of the tiles T on both sides of the short joint material 6 to prevent the tiles T from falling off.

In this state, concrete is placed inside the tile T, removed from the mold after curing, and the tile holding device according to the present invention is removed from the tile installation surface leaving the tile hanging pieces 9 behind, and if necessary, the joints are filled. Then, the tiled wall surface is finished as shown in FIG.

Although the order in which the tiles and joint material are installed is not limited, usually the short joint material 6, the holding member 8, and the tile hanging piece 9 are combined, and this combination and the tile T are placed in adjacent lengths. A method is adopted in which they are arranged alternately on the joint material 4. Further, the through hole 7 and the protruding rod portion 8b may be provided near the upper ends of the short joint material 6 and the flat plate portion 8a, respectively.

The above embodiment is for a case where the formwork panel 1 is installed vertically, and a case where the long gap material 4 is arranged horizontally on the formwork panel 1, but the tile holding device according to the present 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.

Since the tile holding device according to the present invention is configured as described above, the tile can be reliably held in the formwork panel even if there is a dimensional error in the tile, thereby preventing the tile from falling 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.
