2. Description of the Related Art As a simple construction method of tiles, there is a method using joint bars. In this method, apply adhesive to the surface to be tiled, such as a concrete floor such as a terrace, balcony, entrance, or corridor, place a long joint rod, and apply the required number of sheets while applying one side of the tile along the joint rod. Of tiles are laid out, and joint bars cut to the length of one side of the tile are interposed between adjacent tiles. After the tiles are laid along the long joint bars, the long joint bars are arranged along the side of the tile opposite to the side along the joint bars. Then, tiles are laid along the newly arranged long joint bars in the same manner as above. By repeating this process, tiles can be laid on the floor (Inax Co., Ltd., general catalog '00 -'01, No. 169).
page). According to this dry joint bar construction method, joints are formed by joint bars, so that joint filling with mortar is not required, and tiles can be laid without a skilled worker.

[0003]

When tiles are laid by the above-mentioned conventional dry joint bar construction method, joints along the long joint bars are good as straight joints. The joints formed by cutting and arranging the joints to lengths are difficult to align in a straight line due to a tile dimensional error and a tile arrangement error at the time of construction, and the joints may be poor.

An object of the present invention is to solve such a problem and to provide a tile laying structure using joint bars having good joints both vertically and horizontally.

[0005]

According to the present invention, there is provided a tile laying structure comprising: a rectangular base plate having a ridge provided on a peripheral edge thereof; and a joint bar installed on the base plate in a cross-shaped combination.
A tile fitted between the joint bars and between the joint bars and the ridges.

[0006] In such a tile laying structure, joint bars are vertically and horizontally combined in a grid-like (lattice-like) arrangement.
Since the tiles are fitted and arranged between the joint bars and between the joint bars and the ridges, the joints are good both vertically and horizontally.

[0007] In the present invention, the height of the ridge is substantially the same as the height of the joint bar, and the thickness of the ridge is preferably about half the thickness of the joint bar. With this configuration, when a plurality of base plates are abutted and the ridges of adjacent base plates are overlapped with each other, the total thickness of the two ridges becomes the same as one joint bar, and The joints have the same width as the whole construction surface. Also, the joints have the same height (depth) over the entire tile construction surface.

When the base plates are butted against each other,
It is preferable to connect by a connecting member so as not to move.

In the present invention, it is preferable that the base plate is provided with a drain hole and a mounting hole for the joint bar, and the joint bar preferably has a projection engaged with the mounting hole. According to this structure, the joint bars can be easily attached and detached, and the drain holes can be used for draining water and removing air when the tiles are mounted.
