Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor laying type composite flooring in which a tread such as a plurality of tiles is assembled on the upper surface of a floor frame so that the floor surface of the tread can be constructed by a simple operation. The present invention relates to a composite flooring material suitable as a flooring material or an entrance flooring material.

[0002]

2. Description of the Related Art When a tile floor surface such as a balcony or an entrance is to be constructed, the wet method requires a professional craftsman and cannot be constructed by anyone. Therefore, there is provided a composite flooring material capable of easily constructing a tile floor surface by a dry method.

As a floor-laying composite flooring of this type, conventionally,
The one described in Japanese Utility Model Publication No. 3-68254 is known. This composite flooring material is obtained by joining tiles to the upper surface of each tile laying portion of a frame body having a plurality of tile laying portions arranged in a grid pattern.

In this case, the frame body has a square bottom plate formed in a grid pattern, and nine tile laying portions, three in total in vertical and horizontal directions, are formed as recesses on the upper surface of the bottom plate, and each tile laying portion is formed. Square tiles are placed on the upper surface of each.
Further, the partition walls that define each tile laying portion are provided with protruding tile holding pieces at the four corners, respectively, and these tile holding pieces hold down the four corners of the tiles housed in the tile laying portion. , Tiles are fixed to the frame. Further, a hook portion is provided on two adjacent sides of the frame body, and an engaging portion with which the hook portion engages is provided on the remaining two sides. When a plurality of composite floor materials are laid, the adjacent composite floors are provided. The frame bodies of the material can be connected to each other by the hook portion and the engaging portion.

In this composite flooring, the tiles are fixed to the frame by elastic tile holding pieces provided on the partition walls.
As another example, one in which a flange piece having elasticity in a diagonally downward direction is extended on a partition wall and the side portion of the tile is supported by the flange piece (Japanese Utility Model Publication No. 4-7205, etc.), the tile is made into a resin mat with an adhesive. Those that are fixed (actual Kaihei 6-14344)
Japanese Patent Publication No. 3-32561, etc.), and when the tiles are wooden bricks, those that fix the bricks with screws from below (Japanese Patent Laid-Open No. 4-85401, etc.) are known.

[0006]

By the way, in the conventional composite flooring, the tiles are joined by the elastic holding piece or the elastic brim piece formed on the frame, by using an adhesive, or from below. Since I am stopping with screws, there were the following problems, respectively.

That is, in the case where the tile is fixed by the elastic holding piece or the elastic brim piece formed on the frame, the tile is attached and detached while bending the holding piece and the brim piece, so that the detachment itself can be easily performed. The force to press the tiles could not be increased so much that it could come off during transportation or construction. Further, there is also a problem that when repeatedly detached, the holding piece and the collar piece are deformed and the fixing force is reduced.

Further, in the case of joining using an adhesive,
The joining process is very tedious and time consuming, and once glued, the tiles cannot be removed freely, so even if one tile is damaged, the entire composite flooring must be replaced and maintenance costs are high. There was a problem.

[0009] Further, there is a problem in that when the screws are fixed from below, the mounting work is troublesome and it is difficult to adopt them for ceramic tiles.

The present invention has been made in view of the above circumstances. It is possible to easily attach and detach a tread plate such as a tile to and from a frame body, which has good maintainability, and stably holds even when the tile is repeatedly attached and detached. It is an object of the present invention to provide a composite flooring material which can be realized and which can be easily implemented even in the case of a tile made of ceramic or the like and which can be realized at a low cost.
