Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to an inorganic wall covering material for construction.

[Prior Art] Conventionally, there is known a ventilation construction method in which a ventilation layer is provided inside a wall for the purpose of preventing dew condensation inside the wall of a building. When this construction method is adopted, as shown in Fig. 4, the pillars 4 and studs 5 of the building
The waterproof paper 3 is attached to the above, the furring strip 6 is attached thereon, the ventilation layer 7 is secured, and the wall covering 1 is attached to the furring strip.

However, when constructing using such wall coverings,
The step of attaching the furring strip and the step of attaching the wall covering material are different, and there is a problem that the workability is low. Further, when the horizontal furring strip 8 is provided, the waterproof paper is sandwiched between the furring strip and the flat back surface of the main body as shown in FIG. Since it stays, there is a problem that water enters the room.

[Problems to be Solved by the Invention] The present invention solves the above problems of the prior art and is excellent in workability, and provides a wall covering material in which water dropped from above stays at the lateral furring strip. To aim.

[Means for Solving the Problem] The present invention provides an inorganic wall covering material in which a groove for ventilation is provided on the back surface and waterproof paper is attached so as not to close the groove.

A description will be given below with reference to the drawings. FIG. 1 is a perspective view of a wall covering material (waterproof paper is omitted) according to the present invention. The wall covering 1 is made of an inorganic material such as lightweight foamed concrete or fiber reinforced concrete, and has a groove 2 for ventilation on its back surface. If the depth of the groove is too shallow or the width is too narrow, the ventilation resistance increases and dew condensation occurs on the column, which is not preferable. On the other hand, if the depth is too large or the width is too wide, the strength is lowered, which is not preferable. The preferred groove depth is deeper than 3 mm and is less than 50% of the wall covering thickness.

The preferable width of the groove is in the range of 3 to 30 mm.

It is preferable to provide the groove portion over the entire length of the wall covering material so that the groove portion becomes vertical when the wall covering material is constructed, because excellent air permeability can be secured. The size of the wall covering is not particularly limited, for example, in the case of fiber reinforced concrete 1820 mm length × 45
It can be used from 5mm width x 12mm thickness to 3030mm length x 455mm width x 16mm thickness.

Although not shown in the drawings, by attaching the waterproof paper to the back surface of the wall covering material, the step of attaching the waterproof paper at the construction site can be omitted and the workability is improved.

In that case, the waterproof paper is attached with an adhesive or the like so as not to block the groove. It is particularly preferable to use the waterproof paper which is larger than the length of the wall covering material by about 5 to 15 cm, because when the construction is performed, the joint between the adjacent wall covering material is reliably sealed.

FIG. 2 is a horizontal cross-sectional view of the wall covering material according to the present invention vertically attached. Attach the wall covering 1 to the pillars 4 and the studs 5 as shown in the figure. A groove portion 2 is provided on the back surface of the wall covering material, and waterproof paper 3 is attached so as not to close the groove.

FIG. 3 is a horizontal cross-sectional view of a construction example in which the wall covering material according to the present invention is provided at a portion having the lateral furring strip 8.

The water that has fallen along the waterproof paper from above falls further downward through the groove 2 at the lateral furring strip 8, and is discharged to the outside and does not stay there.

Therefore, there is no possibility that water will mix into the room from such a part.

[Advantage of the Invention] According to the present invention, since the step of attaching the furring strip on the site can be omitted, the workability is significantly improved. Further, since the waterproof paper is attached to the back surface, the step of attaching the waterproof paper on site can be omitted and the workability can be further improved.
Further, even when the construction is performed by using the horizontal furring strip, water does not stay in the furring strip portion, so there is no risk of water entering the room.
