Description

Description: TECHNICAL FIELD The present invention relates to a building interior / exterior material using a large porcelain plate and a building interior / exterior construction method using the interior / exterior material.

[Conventional technology]

Conventionally, large porcelain plates (ceramic plates) used as interior and exterior materials for concrete buildings are formed in a rectangular shape, and a backing material such as gypsum board is attached and fixed to the back surface of the plate. This large porcelain board is arranged and fixed to the wall surface by adhering it with an adhesive, and the joints formed between the porcelain boards are treated with caulking material to finish the interior and exterior of the wall surface.

[Problems to be solved by the invention] By the way, a large porcelain plate is heavy because it uses, for example, a 30 cm square ceramic plate, and since the concrete wall surface to be attached with an adhesive has irregularities, sufficient fixing strength is required. It is difficult to obtain and there is a risk of peeling and dropping.

Therefore, the object of the present invention is to solve the above-mentioned problems, in order to firmly fix a large porcelain plate regardless of the condition of the concrete wall surface, a building interior and exterior material, and a building using this exterior material. It is an object of the present invention to provide a building interior / exterior construction method that enables efficient and clean construction of interior and exterior of buildings.

[Means for Solving the Problems]

In order to solve the above problems, a first aspect of the present invention is to provide a ceramic plate and a backing material, which are formed in a rectangular shape of the same size,
The backing material protrudes from the two adjacent sides of the ceramic plate, and the two remaining sides of the ceramic plate are overlapped and fixed so that they protrude from the backing material, and a hard plate with screw holes is attached to the part of the backing material protruding from the ceramic plate. It has a fixed structure.

According to a second aspect of the present invention, a ceramic plate and a backing material formed in a rectangular shape of the same size are stacked so that the backing material projects from two adjacent sides of the ceramic plate and the remaining two sides of the ceramic plate project from the backing material. Used as a building interior / exterior material in which a hard plate having screw holes is fixed to the part of the backing material protruding from the ceramic plate. It is fixed to the wall surface of the building with screws inserted into the screw holes of the hard plate so as to be arranged in an overlapping manner, and the interior and exterior surfaces are formed by the ceramic plates of the interior and exterior materials.

[Action]

The interior / exterior material is fixed to the wall surface by stacking the interior / exterior material on the wall surface of the concrete building and screwing a screw inserted into a screw hole provided in the hard plate into the wall surface. The interior / exterior material placed adjacent to this interior / exterior material is fixed so that the protruding portion of the ceramic plate overlaps the backing material of the mating interior / exterior material. The joints are arranged on the wall surface and the joints formed between the adjacent ceramic plates of the interior and exterior materials are treated with a caulking material as needed to finish.

〔Example〕

Embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in FIG. 1 and FIG. 2, the interior / exterior material 1 includes a large porcelain plate 2 (hereinafter referred to as a ceramic plate) and a backing material 3 which is fixed on the back surface of the ceramic plate 2 by a method such as adhesion. When,
The hard plate 4 is fixed to the surface of the backing material 3 protruding from two adjacent sides of the ceramic plate 2.

The ceramic plate 2 and the backing material 3 are both formed in a rectangular shape of the same size, and as shown in FIG. 1, two sides of the backing material 3 project from two adjacent sides of the ceramic plate 2 by the same length. The two sides of the ceramic plate 2 are projected from the backing material 3 by shifting the positions and fixing them.

The backing material 3 is formed by using a gypsum board, a calcium silicate plate, or the like, and a hard plate 4 provided on a portion of the backing material 3 protruding from the ceramic plate 2 is made of aluminum or the like as shown in FIG. It is made of a material and has an L-shaped cross section, and is bonded and fixed so as to cover the entire length of the protruding portion 3a from the surface to a part of the side surface.

The hard plate 4 is provided with screw holes 5 at appropriate intervals along the length direction, and the screws 6 inserted into the screw holes 5 are screwed into the wall surface to fix the interior / exterior material 1 to the wall surface. It is like this.

The interior / exterior material of the present invention has the above-described structure. Next, an interior / exterior construction method using the interior / exterior material will be described with reference to FIGS. 3 to 5.

As shown in FIG. 3, a metal flat bar 7 is fixed to the wall surface of the concrete building A at intervals corresponding to the size of the interior / exterior material 1, and the leveling of the base is performed. The end portion of 1 is stacked on the flat bar 7, and the screw 6 inserted into the screw hole 5 of the hard plate 4 is screwed from the flat bar 7 toward the building A, and the interior / exterior material 1 is attached to the wall surface.
Immobilize

Each of the interior and exterior materials 1 arranged on the wall surface by the fixing method as described above is positioned so that the protruding portion 2a of the ceramic plate 2 overlaps the protruding portion 3a of the backing material 3, and as shown in FIG.
The ceramic plates 2 are arranged side by side vertically and horizontally so that joints are formed between them.

Between each of the interior and exterior materials 1 adjacent to each other, a gap formed between the backing materials 3 and 3 and a protruding portion 2a of the ceramic plate 2 and the backing material 3,
The gap generated between 3a is sealed by filling caulking material 8 and the joint between the ceramic plates 2 is also caulking material 9
If the processing is performed by filling the inner surface or the outer surface with the ceramic plates 2 of the inner or outer material 1 lined up. The joint may be processed only by butting the ceramic plates 2.

FIG. 5 shows a method of treating the projecting corner portion, in which the flat bars 7, 7 are fixed to the two-sided corners of the building A, and the interior and exterior materials 1 and 1 arranged on the two sides are the backing material 3. The protrusions 3a are fixed so as to face the corners, the corners of the backing material 3 in both the interior and exterior materials 1 and 1 are treated with a backup material 10, and the corner interior and exterior materials are formed in an L shape using a ceramic plate. 11 is overlapped on the protruding portions 3a, 3a of the backing material 3 on both sides, and the overlapping portions and joint portions are fixed by caulking materials 8, 9.

〔effect〕

As described above, according to the present invention, since the hard plate having screw holes is fixed to the surface of the backing material protruding from the two sides of the ceramic plate, the backing material is reinforced by the hard plate,
The interior and exterior materials can be fixed to the wall surface with screws, and the interior and exterior materials are firmly fixed regardless of the base conditions of the wall surface, and the interior and exterior material that uses a large and heavy ceramic plate is used for the interior and exterior of the wall surface. can do.
