Description

TECHNICAL FIELD The present invention relates to a construction structure and a construction method for a surface material such as tiles and ceramics building materials, and particularly to a construction structure and a construction method suitable for construction of a large surface material. .

[Prior Art] Conventionally, for example, as a method of applying a large tile of 300 mm square or more to a wall surface, as shown in FIG. 5 (a), a base 3 is formed on the surface of a frame 2 on which the tile 1 is installed, A wet construction method in which the tile 1 is pressure-bonded using the cement mortar 4 (see FIG. 5B), or a construction method in which the tile 1 is pressure-bonded using an organic adhesive is generally adopted.

In addition, as a dry construction method of tiles, as shown in FIG. 6, the tiles 1 are mounted on the base 3 formed on the tile construction surface with the metal fittings 5.
There is also a method of fixing using.

[Problems to be Solved by the Invention] However, among the conventional tile construction methods, the wet construction method has the following problems.

At least one week of curing is required from base preparation to tile application, the construction period is long, and it cannot be used immediately after application.

Especially when the tiles are large, there is a risk that the tiles may slip off due to their own weight during construction. Therefore, it may be necessary to temporarily fix the tiles, which increases the man-hours. Moreover, if a wedge is sandwiched between the tile to be pasted and the tile in the lower row as a temporary fixing of the tile, the work must be waited until the tile in the lower row is fixed, and the construction period is Not only is it significantly extended, but for that purpose tiles have to be pasted from bottom to top, so on a wall surface that requires scaffolding, the scaffolding cannot be removed until the work is completed, and construction work is not easy .

Since the tiles that have been pasted and fixed cannot be easily peeled off, it takes a lot of trouble to repair or change the pattern.

On the other hand, the dry construction method does not have such a problem,
Since no adhesive is used, it is necessary to use a fixing member for the tile having a shape capable of pressing the tile in the body pressing direction. Therefore, the metal fittings 5 for fixing the tiles
As shown in FIG. 6, a part of the metal fitting 5a was exposed on the tile surface, and the appearance of the tile construction surface was significantly impaired.

[Means for Solving Problems] The structure of the present invention is a structure in which a surface material is attached to a construction wall surface of a surface material via horizontal rail members fixed in parallel to each other, and the rail member is The rail member is fixed to the wall surface in a state where the contact surface provided on the back surface of the center portion in the height direction of the rail member is in contact with the wall surface, and the rail member includes a plurality of surface materials. The projecting piece has a length that can be supported and that extends in the longitudinal direction and projects to the front side. The projecting piece is arranged on the upper side and the lower side of the projecting piece, apart from the wall surface, and is arranged forward by a required distance, and the wall surface. The rail member is provided with a support piece portion projecting in the back direction from the back side of the surface material attachment surface and having a tip abutting against the wall surface. The surface material has an upper edge portion and an adhesive, a double-sided tape or Is fixed by a flat fastener, and the lower side of the surface material is locked to the projecting piece of the rail member.

In the method of the present invention, first, the rail member is fixed to the wall surface, and then the surface material is bonded to the mounting surface by using an adhesive, a double-sided tape or a flat fastener, and at this time, the lower side of the surface material is projected. It is locked on one side.

[Operation] In the present invention, the projection of the rail member supports the surface material's own weight, and the adhesive, the double-sided tape, or the flat fastener functions to prevent the surface material from moving in the out-of-plane direction (the direction away from the body). I am doing it.

According to the present invention, the surface material is affixed with an adhesive, a double-sided tape or a flat fastener, so that no curing is required. Further, the surface materials can be attached in order from the top, the workability can be improved, the construction period can be shortened, and the surface material can be prevented from being peeled off due to being supported by the protrusions. Further, since the adhesive, the double-sided tape, or the flat fastener is used for the attachment, the attachment is extremely easy and can be removed relatively easily.

Further, the surface material mounting surface is provided farther from the front side of the wall surface than the contact surface on which the rail member is mounted on the wall surface. Therefore, it is possible to form a recessed portion that is recessed from the front side of the rail member, and house the head of a screw or an anchor bolt for mounting the rail member on the wall surface in this recessed portion. Further, the backing material on the back surface of the surface material can be housed in the space formed by the contact surface and the back surface of the surface material.

In addition, since the rail member used in the present invention does not need to be exposed to the surface of the surface material such as a metal fitting used in the conventional dry construction method, the appearance of the construction surface is not spoiled.
