Abstract

PURPOSE:To enhance connecting strength of panels by fixing a panel formed in sandwich structure to a wall ground made from structural steels or the like with its fixing groove fixed thereto with a fixture, and by making the panel connected with another panel that comes above thereof by inserting a female fitting groove of the upper panel into an edge of the lower panel. CONSTITUTION:A panel A of sandwich structure is formed of a surface material 1 and a reverse-side material 18 made of metal or synthetic resin and a core material 21 that is foamed first and cured later. The panel A1 on the nth stage is fixed with a fixture beta to a wall ground alpha made from structural steel backing or the like. Then a female fitting groove 16 of the panel A2 on the nth plus one stage is dropped onto a edge 8 of the panel A1 and, at the same time, an engaging piece 23 thereof is inserted into an engaging groove 22 of the panel A1, forming horizontal joints therewith. Such process of work is repeated, starting from a ground-sill, until it reaches a girder, and the entire wall body is constructed therewith. Thereby fixing of the panels to the wall ground can be made without fail with improved workability, making waterproofness and airtightness therefor improved, too.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to architectural panels (hereinafter simply referred to as panels) useful for constructing outer and inner walls of buildings, structures, and dyed materials. 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 stretched horizontally.

[Conventional technology]

Conventionally, as shown in Fig. 12, this type of panel has been constructed by connecting panel a, which has a real structure on the back side, with a male-female mating structure, and fixing the end of panel a+ to the wall base α. A fixing device using a tool β has been devised.

(Problem to be Solved by the Invention) However, a gap T is formed between panels a1 and 32 by the head of the fixing tool β, and rainwater etc. blown up from the joint part is absorbed by the wall base due to this large gap γ. There was a drawback that it was transmitted to the α side and corroded the wall base α.
is formed near the joint, rainwater, etc. will directly reach the head of fixture β and the fixing hole drilled in panel al by fixture β, resulting in rusting of fixture β, There were drawbacks such as rainwater entering the wall base α through the fixing holes. Furthermore, the fixture β was visible from the outside through the gap between the joints, resulting in a greatly inferior aesthetic appearance.

[Means to solve the problem]

In order to eliminate such drawbacks, the present invention fixes the panel at one end, and also fixes it from the surface side of the surface material by using the fixing groove of the male connecting part and the upper surface of the female connecting part. At the same time, a cover piece is formed on the side wall of the female type coupling part that protrudes outward to prevent the fixing device from being exposed to the outside by its shadow, and the gap formed by the cover piece is caused by capillary action. The purpose of the present invention is to provide a panel that improves waterproofness by preventing this, and further enhances fire resistance, airtightness, waterproofness, and engagement force by making the connection structure on the wall base side of the panel a real structure.

〔Example〕

The panel according to the present invention will be described in detail below with reference to the drawings. FIG. 1 is a representative example of the above-mentioned panel A, which has a sandwich structure consisting of a top surface material, a back surface material 2, and a core material 21. The top surface material and the back surface material (■) are made of thin metal sheets or synthetic resin materials, such as A2, Fe, etc.
, Cu, stainless steel, aluminum/zinc alloy plated steel sheet,
It is a type of colored steel plate, enameled steel plate, fluororesin coated steel plate, clad steel plate, sandwich steel plate, etc., formed by press molding, extrusion molding, roll forming, etc.

To explain in more detail, on the surface material, as shown in FIG. 2, a gutter-like part 1a is formed from a horizontally long decorative surface part I, a male type connecting part ↑, and a female type connecting part U, and the decorative surface part λ a side wall 3 in which one end edge in the longitudinal direction of the decorative surface 2a is bent inward at an arbitrary angle; and a joint base 4 in which the lower end edge of the side wall 3 protrudes outward;
It is formed from a covering piece 5 whose other end is bent inward, and a side wall 6 with the tip of the covering piece 5 hanging downward. The male-type connecting part 7 has an insertion edge 8 consisting of an upper edge 9 with the tip of the joint base 4 protruding further outward, and a lower edge 1° with the tip of the upper edge 9 bent inward in a substantially U-shape. , a concave fixing groove 11 formed on the upper edge 9 of the insertion edge 8, and a reinforcing piece 12 with the tip of the lower edge 10 bent inward in an L-shape. As shown in FIG. 4, the insertion edge 8 is a part that is inserted into a fitting groove 16 of a female type connecting part U to be described later and is fixed to the wall base α, and is also a part that is fixed to the wall base α.
This is the part that functions as a fixing part for fixing the panel A to the wall base α by driving fixing tools β such as nails into the wall base α. Further, the concave fixing groove 11 is formed to be larger than the height and width of the nail head of the fixing tool β, so that the fixing tool β does not protrude above the surface of the joint basement 4, and the panel A is not engaged. When doing so, no gap is formed at the contact area between the upper surface 14, the joint base 4, and the upper edge 9, which will be described later, and the fixing groove 11 forms a gap to prevent capillary phenomenon and strengthen waterproofness. It is something. Furthermore, the reinforcing piece 12 is used to reinforce the male connecting part on the surface material - side, and as shown in Fig. 4, the connecting part to the panel.
When fixing the panel A to the fixing groove 11, the reinforcing piece 12 is also fixed by the fixing tool β, and when the insertion edge 8 is inserted into the fitting groove 16, the insertion edge 8 is the bottom surface 15
This helps prevent deformation due to pressure and ensures secure fixation. The female connecting portion U is formed into a substantially U-shaped cross section by an upper surface 14 that is bent inward at the lower edge of the side wall 6, a lower surface 15 that is bent outward at the tip of the upper surface 14, and the upper surface 14 and the lower surface I5. It consists of a fitting groove 16 and a reinforcing piece 17 whose tip of the lower surface 15 projects inward.

This fitting groove 16 is a portion that is engaged with the insertion edge 8 of the male connecting portion yu and fixes the panel A to the wall base α.

The steps 2b and 2c formed on the decorative surface 2a are intended to make the decorative joints step-like, thereby making the joints three-dimensional and clear, and improving the design. Furthermore, cover piece 5
As shown in FIG. 4, the fixture β covers the upper part of the joint base 4 and covers the boundary between the side wall 6 and the joint base 4, and the boundary is not visible from the outside due to the shading. This prevents exposure to the outside, and forms a first waterproof layer (prevents capillary phenomenon) by the gap T formed in the cover piece 5. As shown in Fig. 3, the "back material" is an inner piece 19 bent inwardly in a shape that is approximately parallel to the board material, and the other end thereof is outwardly bent into a "plate material". In the figure, the tips of the inner piece 19 and the outer piece 20 are bent upward to form a stable piece 19.
a, 20a are formed to function as a guide surface during engagement and a mold during production, and a gutter-like portion 18a is formed from these. This backing material ■ covers the backside of the core material 21 to be described later, making panel A a sandwich structure, improving the mechanical strength of panel A itself, and improving the mechanical strength of panel A, as well as noncombustible sheets, waterproof membranes, heat shielding sheets, water absorbing sheets, and soundproofing sheets. , serves as a backing material, etc., and its material may be the same material as the surface material, or asbestos paper, kraft paper, asphalt felt, or metal.
I, Fe, Pb, Cu), synthetic resin sheet,
It is made of a laminate of one or more of rubber sheets, cloth sheets, gypsum paper, aluminum hydroxide paper, glass fiber nonwoven fabric, etc., or sheets that have been treated with waterproofing or flame retardant treatment. The mounting is carried out by integrally forming an engagement groove 22 with a concave cross section by the lower edge 10, the core material 21, and the inner piece 19, and a convex cross section by the lower surface 15, the core material 21, and the outer piece 20. As shown in FIG. 4, as shown in FIG. Base α
This is for fixing panel A to. In addition, the inner piece 19 and the outer piece 20 of the "back material" are intended to greatly improve fire resistance, waterproofness, and airtightness at the connection part, and are especially designed to prevent fire from reaching the back surface in the unlikely event of a fire. This is to prevent infiltration and make Panel A capable of passing the fire resistance test. In addition, in the figure, in order to further improve fire resistance, the top surface material and the back surface material (2) are formed so as not to come into contact with each other. The core material 21 is mainly made of synthetic resin foam, and contains heat insulating material, reinforcing material,
It functions as a soundproofing material, a cushioning material, a fireproofing material, an adhesive material, etc., and is difficult to use for synthetic resin foams such as polyisocyanurate foam, phenol foam, polyurea foam, and polyimide foam, and for these synthetic resin foams. Flame retardants (borates, silicates, phosphates, etc.), flame retardant aids (
gypsum slag, talc, shirasu balloons, etc.), aggregates (perlite, glass peas, etc.), fibrous materials (long and short fibers), etc. Coated with phenol foam powder around pearlite and heated. , foamed under pressure, gypsum board, rock wool board, glass wool board, ALC, insulation board, wood chip board, glass wool, etc., and is made of a single material or a combination of multiple materials. In addition, the formation of the core material 21 is shown in the gutter-like portions 1a and 18 on the surface material and on the back material (2).
In addition to filling the surface material (a), the top surface material and the back surface material (■) are also prevented from coming into contact at the connection part, so that even if the top surface material is heated due to a fire, that heat will not be transferred to the back surface material (■). The aim is to improve fire resistance and heat insulation by preventing thermal bridges.
