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 the panel thickness are increased, the male and female fitting structures do not peel off from the wall base, and fixtures such as nails are not exposed to the outside. It relates to a panel that can be stretched horizontally.

[Conventional technology]

Conventionally, as this type of panel, as shown in FIG. 9, 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. It was to be fixed by a fixing tool β.

[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, and rainwater or the like blown up from the joint b enters the wall foundation α side from the gap γ, and the wall foundation α
Had the disadvantage of corroding.

Also, since the fixing tool β is formed near the joint portion b, the blown-up rainwater or the like directly reaches the head of the fixing tool β, the fixing hole drilled by the fixing tool β,
Fixing tool β, rusting of fixing tool, wall foundation α from fixing hole
There were drawbacks such as infiltration of rainwater into the sea. Furthermore, the head of the fixing tool β was visible from the outside through the gap between the joints b, and the appearance and the design were greatly inferior. Also, although one end of the back material is fixed to the wall base α by a fixture,
The other end was free and weak against external forces such as earthquake resistance and wind pressure resistance.

[Means for solving the problem]

In order to eliminate such a defect, the present invention uses a thin metal sheet for the front and back surfaces, and has a structure in which the front and back surfaces are not in contact with each other at the connection portion. A structure that engages with the back surface material of the adjacent panel and is fixed to the wall base, and furthermore, a male part is formed at one end on the fixed part side of the panel and a female part is formed at the other end, and the fixed part is female. It is an object of the present invention to provide a panel having a structure that can be covered by a real cover part.

〔Example〕

Hereinafter, a panel according to the present invention will be described in detail with reference to the drawings. FIG. 1 shows a representative example of the panel A, which is a panel A having a sandwich structure including a front surface material 1 , a back surface material 12 , and a core material 15. The front surface material 1 and the back surface material 12 are made of a thin metal plate, for example, Al, Fe, Cu, stainless steel, aluminum.
A type of zinc alloy-plated steel plate, color steel plate, enameled steel plate, fluorocarbon resin coated steel plate, clad steel plate, sandwich steel plate, etc., formed by roll forming, press forming, extrusion forming, etc., and the panel A shown in FIG. Face
2. A male part 16 and a female part 17 are formed. More specifically, as shown in FIG. 2, the surface material 1 has a decorative surface portion 2 including a decorative surface 3 forming a wall surface when a wall is formed, and one end edge of the decorative surface 3 bent inward. Side wall 4
An eye basement / fixing piece 6 (hereinafter simply referred to as an eye basement) in which the lower edge of the side wall 4 is bent outward substantially in parallel with the decorative surface 3;
In addition to the reinforcing piece 7 in which the tip of the underground base 6 is bent inward, a fixing groove 5a formed by concavely recessing the underground base 6 in the longitudinal direction, and the decorative surface 3 A cover portion 8 including a side wall 9 having an edge bent inward, an upper edge 10 having a lower end of the side wall 9 bent inward, and a reinforcing piece 11 having a tip of the upper edge 10 bent inwardly. Thus, a gutter-like portion 1a is formed. Also, as shown in FIG. 3, the back material 12 has a notch 13 and a projecting piece 14 formed by bending one end edge of the plate material made of the above material inward and outward, and bending the other end edge into a shape. Furthermore, notch 1
3, the tip of the protruding piece 14 is bent inward to form a stable piece 13
a and 14a, and a gutter upper portion 12a is formed from these. More specifically, the notch 13 and the projecting piece 14 are combined as shown in FIG. 4, and the projecting piece 14 is fixed to the wall foundation α by the notch 13 fixed to the wall foundation α by the fixing tool β. Things. The core material 15 mainly uses a synthetic resin foam and functions as a heat insulating material, a waterproof material, a soundproof material, a buffer material, a fireproof material, and the like.For example, a polyisocyanurate foam, a phenol foam, a polyurea foam, a polyimide foam Synthetic resin foams, and flame retardants (borate, silicate, phosphate, etc.), flame retardant aids (gypsum slag, talc, shirasu balloon, etc.), aggregates (pearlite, glass, etc.) Beads, etc., fibrous materials (long and short fibers), etc., phenol foam powder coated around pearlite, heated and pressurized and foamed, gypsum board, rock wool board, Glass wool board, ALC, insulation board, wood chip board, glass wool, etc., formed from a single material or a combination of multiple materials That. The core material 15 is formed by filling the gutter-like portions 1a and 12a of the front surface material 1 and the back surface material 12 and preventing the reinforcing piece 7 from being in contact with the stabilizing piece 13a and the reinforcing piece 11 from being in contact with the stabilizing piece 14a. Even if the front surface material 1 is heated by a fire or the like, the heat is prevented from being transmitted to the back surface material 12 , and the panels A ₁ and A ₂ are also connected at the connecting portion between the panels A as shown in FIG.
There is no contact between the front surface material 1 and the back surface material 12 , and the prevention of thermal bridges and the improvement of fire resistance are achieved. The male part 16 and the female part 17 are formed by the surface material 1 and the end of the back material 12 , and the male part 16 is composed of the underground base 6, the core 15, and the notch 13.
The female part 17 is composed of the upper edge 10, the core material 15, and the projecting piece 14. The female part 17 is, as shown in FIG.

〔The invention's effect〕

According to the panel of the present invention as described above,
Since the fixing to the frame is made at one end edge of the back surface material, even if the decorative surface (surface material) is heated by solar heat or the like and the metal plate expands and contracts, the expansion and contraction does not adversely affect the fixing portion. Since there is no deformation of the decorative surface, the design can be maintained for a long time.
Large panels can be securely fixed to the wall base without exposing nails, bolts, etc. to the outside. Even when the panels are fixed to the base of the wall and connected, the front and back members between the panels do not come into contact with each other, and it is possible to reliably prevent a thermal bridge from the front to back members during a fire. . The length of the upper surface is longer than the position of the fixing groove, and the head of the fixing tool is inserted into the fixing groove, preventing the fixing tool from being exposed to the outside, waterproofing, airtightness, corrosion resistance Thus, a durable wall can be formed. The backing material itself has a structure fixed to the wall base at both ends, and is resistant to external forces such as earthquake resistance, wind pressure resistance, and deformation during fire. There are features and effects such as.
