Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a building panel (hereinafter simply referred to as a panel) useful for constructing an outer wall and an inner wall of a building and a building. More specifically, even if the decorative surface width and panel thickness are increased, the male and female mating structures do not peel off from the wall base, and the fixing tools such as screw screws are not exposed to the outside. The present invention relates to a panel that can be stretched horizontally and has greatly improved waterproofness.

[Conventional technology]

Conventionally, as this type of panel, as shown in FIG. 6, a panel a having a real structure formed on the back side is connected by a male-female fitting structure, and an end of the panel a _{1 is} attached to a wall base α. A fixing device using a fixing tool β has been proposed.

[Problems to be solved by the invention]

However, a gap γ is formed between the panels a ₁ and a ₂ by the head of the fixing tool β to the innermost part of the engagement groove, and rainwater or the like blown up from the joint b is formed by the large gap γ. There is a disadvantage that the light is transmitted to the α side and corrodes the wall foundation α.
Moreover, since the fixing tool β is formed near the joint portion b,
Fasteners beta to rainwater directly head for thus reaching the fixing hole drilled in the panel a ₁ by fasteners beta, rusting fixtures beta, rainwater from the fixing hole to wall base α There were drawbacks such as corrosion of the wall base α due to intrusion. Furthermore, the fixing tool β was visible from the outside through the gap in the joint portion b, and the aesthetic appearance was significantly poor. The reinforcing piece c formed in the core material is fixed by the fixing tool β. However, when the panel a ₁ is fixed by the fixing tool β, the reinforcing piece c is deformed and the fixing piece β is fixed. It was extremely difficult to cast, which was a major drawback in construction.

[Means for solving the problem]

According to the present invention, in order to eliminate such disadvantages, the panel is fixed at one end, and also as the fixing from the surface side of the surface material, the panel is formed on the fixing groove of the male connecting portion and the upper surface of the female connecting portion. Grooves cover the fixtures to improve waterproofness and aesthetics.Also, the combination of the drop-in structure and the actual structure improves waterproofness and workability. It is intended to provide a panel with improved workability as a structure in which the reinforcing piece is not fixed by a fixing tool.

[Other Examples]

What has been described above is merely an example of the panel A according to the present invention, and can be formed into a shape as shown in FIGS. 5 (a) to 5 (h).

〔The invention's effect〕

According to the panel of the present invention as described above,
In fixing to the wall base, a portion where the core material and the back surface material are present in the lower layer at one edge of the surface material is fixed, so that the panel is securely fixed to the wall base and does not peel off. Large panels can be securely fixed to the wall base without exposing nails, bolts, etc. to the outside. Due to the grooves formed on the upper surface of the female connecting portion, a double capillary action preventing space is formed in combination with the fixing groove, and the upper edge of the male connecting portion and the upper surface of the female connecting portion are engaged. Sometimes, they are almost in contact with each other, and the prevention of the capillary phenomenon and the sealing make it possible to enhance the waterproofness which has not been achieved in the past. Since the middle of the upper edge is depressed in a concave shape along the longitudinal direction and a fixing groove larger than the width of the head of the fixture and the height is formed, the fixture does not protrude from the upper edge, eye underground,
Waterproofness, airtightness, and workability can be improved. Since the length of the upper surface is formed to be equal to or longer than the position of the fixing groove and the female connecting portion is formed with a side wall for closing the opening of the connecting portion, the fixing tool is not exposed to the outside. Even if a slight error occurs in the joint width, the fixing tool is not seen from the outside. Due to the extension and the cutout formed in the backing material, rain water due to fire, heat, wind and rain due to fire does not enter the wall base. Since the reinforcing piece formed on the male connecting portion side of the surface material is formed inside the core material, the integration with the core material is ensured, and the strength of the insertion edge against external force is improved. Since the reinforcing piece was formed at a position where it was not fixed by the fixture, it did not interfere with the construction. In the case of a structure in which the front surface material and the back surface material do not come into contact even at the connection portion, a thermal bridge is prevented and fire resistance, heat insulation, and dew condensation resistance are improved. Panels with improved waterproofness, airtightness, earthquake resistance, heat insulation, fire resistance, soundproofing, and workability. There are features and effects such as.
