JPH1018552A - External facing panel for building and facing work method using the panel - Google Patents

Abstract

PROBLEM TO BE SOLVED: To preventing dew condensation and show heat insulating effect by providing longitudinal grooves and lateral grooves are preset pitches on the back of an external facing panel for building which is attached to a column provided with a water-proof and moisture-permeable sheet to form an air layer in a space between the panel and the column face. SOLUTION: An external facting building panel 10 formed of a fiber mixed slag gypsum board has rough wide grooves formed into a zigzag shape at preset pitches on the back with lateral grooves 11 and longitudinal grooves. The thickness of the building facing panel 10 is 15-20mm. The widths of lateral and longitudinal grooves 11, 12 are 30-100mm. The depth (d) of the groove is 30-50mm. The pitch of the longitudinal groove is about 1.2-2 times that of the wide groove. A water-proof and moisture- permeable sheet 14 is temporarily attached to a column face 13 and the building facing panel 10 is pasted to the surface and fixed with nails 15. In this way, the lateral grooves 11 and the longitudinal grooves 12 are used as vent holes to form an air layer between the column face 13 and the external facing building panel 10 to prevent dewing. The need for ventilating barrel edges is eliminated, resulting in simple construction and cost decrease for a housing.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an exterior building panel used outside a building and an exterior construction method using the same.

[0002]

2. Description of the Related Art Architectural panels 2 constructed for exterior use
0 is often commercially available with a three-dimensional pattern formed on the surface to improve the appearance as shown in FIG. 3, but the back surface is usually flat, and is provided on the outer surface of the pillar 21 to prevent dew condensation. A gap is formed by attaching the body edge 22 at a predetermined interval, and the above-mentioned building panel 20 is constructed from above. In addition, 2
Reference numeral 3 denotes a nail for fixing the building panel 20.

[0003]

However, in the exterior construction method according to the prior art, in addition to mounting the building panel 20, it is necessary to fix the rim 22 with nails 23 or the like. Was one of the reasons for the cost increase. The present invention has been made in view of such circumstances, and an object of the present invention is to provide an exterior building panel which can omit the attachment of a rim and is relatively inexpensive and an exterior construction method using the same.

[0004]

According to the present invention, there is provided a semiconductor device comprising:
In the exterior building panel described above, a plurality of wide grooves are provided on the back surface of the substrate at predetermined pitches vertically and horizontally. In the exterior construction method according to the second aspect, an exterior building panel having a plurality of wide grooves provided at predetermined pitches in the vertical and horizontal directions on the rear surface of the substrate is constructed with the rear surface side facing the pillar. In the exterior construction method according to a third aspect, a waterproof and moisture-permeable sheet is provided between the back surface of the exterior building panel and the pillar in the exterior construction method according to the second aspect.

In the exterior building panel according to the first aspect and the exterior construction method according to the second and third aspects, wide grooves are formed on the back surface of the substrate at predetermined pitches in the vertical and horizontal directions. Even if it is mounted on a pillar surface, the wide groove serves as a ventilation hole, and a gap is secured. Further, since the exterior building panel is directly attached to the pillar surface, the construction of the rim can be omitted.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described with reference to the accompanying drawings to provide an understanding of the present invention. Here, FIG. 1 is an explanatory view of an exterior construction method using an exterior building panel according to an embodiment of the present invention, and FIG. 2 is a perspective view of the exterior building panel.

As shown in FIG. 2, an exterior building panel 10 according to an embodiment of the present invention has a plate-like shape, and has wide grooves including a horizontal groove 11 and a vertical groove 12 on a rear surface thereof at predetermined pitches. Is formed. The thickness t (see FIG. 1) of the exterior building panel 10 is 15 to 2 in order to maintain sufficient strength.
It is about 0 mm. As a material of the exterior building panel 10, a fiber-mixed slag gypsum plate is mainly used.

When the exterior building panel 10 is formed, a double-girder concavo-convex pattern consisting of horizontal grooves 11 and vertical grooves 12 arranged vertically and horizontally on the back surface is formed. In this case, for example, a horizontal line pattern or brick-like unevenness may be formed on the surface side of the exterior building panel 10, and the surface may be further painted. Width w, w ₁ of the lateral grooves 11 and longitudinal grooves 12 30 to 1
Its depth d at 00mm is a 30 to 50 mm, its vertical pitch p and the width w of the wide groove is formed in about 1.2 to 2 times the w _1.

When this exterior building panel 10 is constructed, as shown in FIG.
4 is temporarily attached, an exterior building panel 10 is attached to the surface thereof, and fixed with nails 15. Here, the waterproof moisture-permeable sheet 1
As No. 4, for example, there is Tyvek (product name) having a thickness of about 0.2 mm. Thereby, the vertical groove 12, the horizontal groove 11
Are air holes, and an air layer is formed between the pillar surface 13 and the exterior building panel 10 to prevent dew condensation and exhibit a heat insulating effect. In addition, 16 is a pillar.

In the above-described embodiment, the wide groove is formed by the vertical groove 12 and the horizontal groove 11, but the present invention is applicable to a crossed parallel diagonal groove or a non-crossed diagonal groove.

[0011]

According to the exterior construction panel according to the first aspect and the exterior construction method according to the second and third aspects, a ventilation gap is formed on the back side of the exterior construction panel by forming a wide groove. , The rim is not required, the construction can be simplified,
This can reduce the cost of the house.
