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 long joints made of an elastic material having the following properties; a plurality of short joints made of an elastic material arranged so as to sandwich the tiles between adjacent long joints and having through holes in the inner and outer directions; and the short joints. a plurality of holding members disposed between the form panel and the formwork panel, both ends of which are fitted into the small gaps, and each of which has an inwardly opening fitting hole; This is a tile holding device for use in the tile tip construction method, which comprises: a protruding rod portion that fits tightly into a fitting hole; and a tile hanging piece that hangs over the back surfaces of adjacent tiles.

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 filler 6 is a rectangular parallelepiped having a length equal to the gap between the adjacent long joint protrusions 4b. A through hole 7 is formed in the center of the length of the short joint filler 6 in the inner and outer directions.

A holding member 8 is arranged between the short joint material 6 and the formwork panel 1 to hold the former to the latter. Same member 8
is made of synthetic resin and consists of a flat plate part 8a and a protrusion part 8b provided on the inner surface of the flat plate part 8a in an inwardly protruding manner for maintaining a distance of a required protrusion height. Further, a fitting hole 9 is formed in the center of the length of the holding member 8 in the inner and outer directions. Both ends of the flat plate portion 8a are connected to the long joint material 4.
It is fitted into a small gap A formed between the mounting groove 4a and the formwork panel 1.

A small flat plate portion 10a is provided inside each of the short joint fillers 6.
A tile hanging piece 1 made of synthetic resin and a protruding rod part 10b provided at the center of its length in an outwardly projecting manner.
0 is assigned to each. The protruding rod portion 10b passes through the through hole 7 of the short joint material 6 and is tightly fitted into the fitting hole 9 of the holding member 8. Further, the flat plate portions 10a extend over the back surfaces of the tiles T on both sides of the short joint material 6, thereby preventing the tiles T from peeling off. In this way, the short joint board 6 and the tile T are held on the formwork panel 1 via the holding member 8 and the tile hanging piece 10.

In this state, concrete is placed inside the tile T, and after curing, it is removed from the mold, and the tile holding device according to the present invention is removed from the tiling surface, leaving the tile hanging piece 10, and if necessary, the tile hanging piece 10 is removed. Stopper 1
The tip of the protruding rod portion 10b of No. 0 is removed, and 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 10 are combined,
This combination and tiles T are arranged alternately on adjacent long joint materials 4. Also, through hole 7
And the fitting hole 9 may be provided near the upper ends of the short joint material 6 and the holding member 8, 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.
