Description

[Detailed Description of the Invention] The present invention relates to an architectural panel useful for forming exterior materials for buildings, structures, or roofing materials by a dry construction method. For the exterior walls of buildings, a structure in which a metal siding material containing heat insulating material is nailed to the rim, as shown in Utility Model Publication No. 50-895, for example, has become popular. However, in this structure, there was no insulation material at all in the male and female connecting portions, and there was a risk that the metal plate, which was a good conductor, would act as a thermal bridge, causing dew condensation or a reduction in insulation performance in this portion. Additionally, when an embossed architectural panel is installed, a gap is created at the fitting part of the insertion edge and the insertion groove, and rainwater flows through this gap.
Alternatively, there were drawbacks such as drafts entering the building and corroding the building materials. Furthermore, when constructing this type of architectural panel, the insert edge and the insert groove are directly in contact with each other and the panel is inserted, resulting in significant damage and often being the main cause of rust. Additionally, when constructing this type of construction panel, the edges are shaped like sharp knives, so there is an extremely high risk of lacerations for workers.

In order to eliminate these drawbacks, the present invention interposes a waterproof sheet so that the metal plates do not come into direct contact with each other at the fitting part when this type of panel is constructed, and the waterproof sheet also provides waterproofness to the fitting part. In addition to providing heat insulation and airtightness, a synthetic resin foam with high heat insulation properties is provided between the base and the metal plate, and the joints formed when the foams come into contact with each other are covered with free ends. The present invention proposes a construction panel that prevents corrosion of the base material and eliminates the risk of workers receiving lacerations when installing it.

An embodiment of the architectural panel according to the present invention will be described in detail below with reference to the drawings. FIG. 1 is a perspective view showing the above-mentioned panel, in which 1 is a main body formed of a thin metal plate so that its cross section is concave, and its bottomed surface is a rectangular decorative surface 1a.
Reference numerals 2 and 3 denote side walls, which are formed by bending both ends of the main body 1 vertically or at an angle (not shown), and the lower edge of the side wall 2 protrudes outward to form a male connecting portion 4. The male connecting portion 4 consists of an insertion edge 5 and a tongue piece 6 whose tip is bent toward the side shown in the figure or toward the opposite side (not shown). Reference numeral 7 denotes a female connecting portion, which is bent inward in the middle of the side wall 3 in a U-shape to form an insertion groove 8, and its lower edge 9 is further extended outward to form an extension portion 10; It consists of a protrusion 11 provided parallel to the side wall 3 and a tongue piece 12 with the tip of the extension part 10 bent outward. Note that the protrusion 11 is provided as necessary, and can also be made to protrude in the opposite direction to that shown in the figure. In particular, the protrusion 11 has the function of airtightness and draining when the male and female type connecting parts 4 and 7 are connected. Numeral 13 is a synthetic resin foam that fills the concave portion formed by the main body 1 and the side walls 2 and 3, and is mainly used for insulation, adhesive, lightweight raising material, cushioning material, sound absorbing material, and Functions as a non-hygroscopic layer. The materials include polyurethane foam, polyisocyanurate foam, phenol foam, vinyl chloride foam,
These include polyimide foam, polyethylene foam, and polyamide foam, and foams are mainly manufactured from raw materials. In addition to the recessed portion, the synthetic resin foam 13 has a portion including the back surface of the extension portion 10 that protrudes downward, except for the area Δl near the insertion edge 5. In particular, this protruding portion has the function of blocking thermal bridges between the heat insulating material, the cushioning material, and the internal structural material such as the main body 1 and the rim, which are exposed to the outside air. 14 is a waterproof sheet that covers the back side of the insertion edge 5 and the back side of the synthetic resin foam 13;
and 1 side wall, and one end portion is the insertion edge 5
The surface of the tip is covered, and the other end functions as a free end 15 that projects horizontally outward from the lower end edge 13a of the protruding part formed below the female connecting part 7 of the synthetic resin foam 13. It is pasted. In particular, the free end 15 functions as a so-called packing material or sealing material that performs the functions of waterproofing, heat insulation, and airtightness of the weakest point when connecting this type of panel. In addition, the materials for the waterproof sheet 14 include waterproof treated asbestos paper and kraft paper.
and waterproof sheets laminated with gypsum paper, synthetic resin film, metal foil, non-woven fabric, or two or more of these, and anti-mold agents, such as metal soap or phenyl acetic acid, on the outer surface of these waterproof sheets. , mercury, phenol compounds, aniline derivatives, benzimidazole derivatives, sulfur compounds, sanisil anilide, etc. are applied to waterproof sheets. The reason why one end of the waterproof sheet 14 is formed to cover the front end surface of the insertion edge 5 is to prevent direct contact between the insertion edge 5 and the insertion groove 8 and to eliminate damage. To improve weather resistance and corrosion resistance, to improve waterproofness, airtightness, and heat insulation by eliminating gaps in the insertion part, and to eliminate the risk of workers getting lacerations due to the insertion edge 5 during construction. etc. Furthermore, free end 1
5 was formed to eliminate gaps that occur at the joints between adjacent architectural panel synthetic resin foams 13, and to strengthen the airtightness and waterproofness of the joints by contact with a sheet-like material. This is to make the function work.

Next, a construction example will be explained.

First, as shown in FIG. 2, the architectural panel ○I is fixed onto the rim 16 with nails 17. Next, the insertion edge 5 of the architectural panel (○) is inserted into the insertion groove 8 of the architectural panel (○), and the metal plates are connected so that they do not come into direct contact with each other. Therefore, in order to form the outer wall etc., it is sufficient to repeat the above-mentioned operations.

What has been described above is only one embodiment of the construction panel according to the present invention, and as shown in FIG. It is also possible to further strengthen the properties and waterproof properties. Although not shown, one end of the waterproof sheet 14 on the front end surface of the insertion edge 5 may be fixed with adhesive, or the waterproof sheets on the side walls may be bonded together with adhesive. You can also do it.

As described above, according to the construction panel according to the present invention, the insertion structure is such that the insertion edge of the construction panel and the insertion groove are in contact with each other with the waterproof sheet interposed, so that the insertion edge and insertion groove are in contact with each other during insertion. There is no damage to the insertion groove, and corrosion resistance is greatly improved. In addition, since the tip of the insertion edge is covered with a flat waterproof sheet, the insertion edge made of embossed plate etc.
It can be smoothly inserted into the insertion groove, and there are no gaps, making it waterproof and airtight. Furthermore, since the highly insulating synthetic resin foam is interposed without direct contact between the base and the main body, the connection part does not become a thermal bridge, and a highly insulating wall can be formed. Additionally, since the free end serves as the lowest waterproof layer and heat insulating layer between architectural panels, it has the characteristic that these performances can be significantly improved.
