Abstract

PURPOSE:To prevent the falling off a building panel caused by the thermal expansion, etc., of the panel by using metallic thin plates for the surface and rear members of the panel and coupling both members without allowing them to come into contact with each other, and then, respectively fixing the surface and rear members to a wall substrate when the panel is fixed to the substrate. CONSTITUTION:A panel A is formed to have a sandwich structure composed of a surface and rear members 1 and 12 respectively formed of metallic thin plates and a core member 30 which is a foamed body of a synthetic resin and a decorated surface section 2 and male and a female coupling sections 26 and 28 are formed on the panel A. The male coupling section 26 is formed of an inserting upper edge 5, the upper surface 18 of a fixing section 13, the male tongue section 27 of the core member 30, and a insertion groove 19 and, at the same time, the female coupling section 28 is formed of a cover section 8, the upper surface 24 of an inserting edge 21, the female tongue section 29 of the core member 30, and the inserting edge 21. The panel A is fixed to a wall substrate by putting the male tongue section 27 in the female tongue section 19, engaging the inserting edge 21 into the insertion groove 19, and fixing the fixing section 13 to the substrate alpha. Therefore, the fixing section is stabilized against the expansion and contraction of the metallic plates due to solar heat, etc.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to architectural panels (hereinafter simply referred to as panels) useful for constructing the outer and inner walls of buildings and structures. More specifically, even if the decorative surface width and panel thickness are increased, the male and female mating structure will not peel off from the wall base, and fixing tools such as nails will not be exposed to the outside.
This relates to panels that can be hung vertically or horizontally.

[Conventional technology]

Conventionally, as shown in FIG. 9, this type of panel consists of connecting panel a with a real structure on the back side using a male-female mating structure, and fixing the end of panel a1 to the wall base α. It was fixed using a tool β.

[Problem to be solved by the invention]

However, a gap T is formed between the panels aIX32 by the head of the fixture β, and rainwater etc. blown up from the joint part enters the wall base α side through this gap γ and corrodes the wall base α. was there.

In addition, since the fixture β is formed near the joint,
The blown-up rainwater directly reaches the head of fixture β and the fixing hole drilled by fixture β, causing rusting of fixture β and the fixing hole, and from the fixing hole to the wall base α. There were drawbacks such as rainwater infiltration. Furthermore, the head of the fixing tool β is visible from the outside through the gap between the joints, resulting in poor aesthetics.
The design quality was greatly inferior. In addition, the mere actual structure formed on the back side is structurally inadequate to pass fire protection tests, fire resistance tests, etc.

[Means to solve the problem]

In order to eliminate such drawbacks, the present invention uses thin metal plates for the front and back materials, and also has a structure in which the front and back materials do not come into contact with each other at the connecting part. Double fixing, fixing from the side and fixing one edge of the backing material, prevents the panel from peeling off due to thermal expansion and contraction of the panel, and deformation of the wall base (earthquake, etc.).It also passes a fire resistance test. Furthermore, the present invention provides a panel in which the width and thickness of the decorative surface can be increased.

A single material such as phenol foam powder coated around the surface and foamed by heating and pressurizing, gypsum board, rock wool board, glass wool board, ALC, insulation board, wood chip board, glass wool, etc. Or, it is formed by combining multiple materials. In addition, the core material 30 is formed by filling the gutter-like portions 1a and 12a for the front surface material 1 and the back surface material, and at the same time, ensuring that the reinforcing pieces 7 and 20 and the reinforcing pieces 11 and 25 do not come into contact with each other. This prevents the heat from being transmitted to the backing material 12 even if the facing material 1 is heated due to a fire or the like, and further, as shown in FIG. There is no contact between the surface material and the back pressure, which improves fire resistance by preventing thermal bridging.

Here, to explain the dimensional relationship of each part, the opening width of the gutter-like parts 1a and 12a on the surface material and the back surface material, that is, the width between the reinforcing pieces 7 and 11, is WI, the reinforcing piece 2° and the reinforcing piece 25
