Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an interior wall material of a building or a building,
It relates to building panels that can be used as exterior wall materials, roofing materials, ceiling materials, flooring materials, partitioning materials, fire doors, etc., and that have no deformation such as swelling or warpage after production and have excellent mechanical strength. is there. 2. Description of the Related Art In general, many architectural panels in which a core material made of a synthetic resin foam is sandwiched between a thin plate-like surface material and a back surface material have been invented, devised, and put on the market. [0003] However, in a building panel using a synthetic resin foam as a core material as described above, when the core material is generally made of various synthetic resin foams, In some cases, the mechanical strength of the building panel itself was inferior, and the surface of the building panel became uneven or warped due to the aging of the synthetic resin foam. According to the present invention, in order to eliminate such a drawback, a core material is sandwiched between a front surface material and a back surface material, and a male and female connection structure is formed at both ends in a width direction. In the building panel, at least the surface material is formed on a keystone-like decorative surface having irregularities, and by forming a pot portion projecting inward between the concave bottom surface and the concave side wall,
An object of the present invention is to propose a building panel in which the mechanical strength of the building panel itself is improved, the bonding strength with the core material is improved, and the building panel is not warped. An embodiment of a building panel according to the present invention will be described below in detail with reference to the drawings. That is, as shown in FIGS. 1 to 3, the building panel A is a building panel A in which a core material 3 made of, for example, a synthetic resin foam is sandwiched between a front surface material 1 and a back surface material 2. As an example of the overall shape of the building panel A, as shown in FIG. 1, a surface material 1 made of a long metal thin plate is used.
A core material 3 is sandwiched between the base material 3 and the back material 2 and is formed from a male connecting portion 4 formed at one end in the width direction, a female connecting portion 5 formed at the other end, and a keystone-like decorative surface 6. . In FIG. 2, α is a frame, and β is a fixture. The front surface material 1 and the back surface material 2 are made of a thin metal plate such as iron, aluminum, copper, stainless steel, titanium,
Zinc alloy plated steel plate, galvalume steel plate, enameled steel plate, clad steel plate, laminated steel plate (PVC steel plate, etc.), sandwich steel plate (damping steel plate, etc.), polyvinyl chloride resin, polycarbonate resin, etc. (Of course, color plates painted in various colors) Roll forming, press forming,
Extruded, press-formed, inorganic materials formed into various shapes by extrusion or the like, hard materials formed into various arbitrary shapes by autoclaving, etc.
Aluminum backed paper, asbestos paper, kraft paper, asphalt felt, metal foil (Al, F
e, Pb, Cu), a synthetic resin sheet, a rubber sheet, a cloth sheet, a gypsum paper, an aluminum hydroxide paper, a glass fiber nonwoven fabric, or a laminate of two or more kinds, or a waterproof treatment or a flame retardant treatment. It consists of a sheet-like material. Of course, calcium silicate board, calcium carbonate board, gypsum board, pearlite cement board, rock wool board, slate board, ALC board, PC
It can also be formed from a hard base material such as a plate, another inorganic lightweight body, or an inorganic lightweight foam. The core material 3 is made of a synthetic resin foam such as a polyurethane foam, a polyisocyanurate foam, a phenol foam, a vinyl chloride foam, a polyethylene foam, a polystyrene foam, and a urea foam. If necessary, a resol-type phenol stock solution, a curing agent, and a foaming agent are mixed, and the mixture is discharged onto the back side of the front surface material 1 or the back surface material 2 and heated to react, foam, and cure. It is. In the core material 3, light-weight aggregates (pearlite particles, glass beads, gypsum slag, talc stone, shirasu balloon, aluminum hydroxide, etc.) and fibrous materials (glass wool, rock wool, carbon fiber, (E.g., graphite) to improve fire resistance and fire resistance. Of course, an inorganic material such as rock wool, glass wool, ceramic wool or the like may be used as the core material 3. More specifically, the male connecting portion 4 is provided on the side surface 1.
a joint 7 having a tip protruding outward, and a lower edge 8 having a joint 7 bent inward and a tip protruding inward.
Insert piece 9 formed from joint 7 and lower edge 8;
A fitting groove 1 formed by an engaging piece 10 having a lower end 8 and an engaging piece 10, the tip of which is bent inward and the tip protrudes outward.
1. The female connecting portion 5 has an insertion groove 12 having a tip of the side surface 1b projecting inwardly in a pot shape, an upper surface 13 having a lower edge of the insertion groove 12 projecting outward, and a tip of the upper surface 13 facing inward. A lower surface 14 which is bent inward and has a tip protruding inward, a fitting piece 15 formed by the upper surface 13 and the lower surface 14, and a lower edge 16 which bends the tip of the lower surface 14 inward and protrudes the tip outward. , Lower surface 1
4, an engagement groove 17 formed from the lower edge 16, a fixing surface 18 projecting the lower edge 16 further outward, and a packing material 19 formed at the innermost part of the engagement groove 17. is there. The keystone-like decorative surface 6 is obtained by forming the surface material 1 in an uneven shape and forming it in a keystone tone (wavy shape). By forming the surface material 1 in an irregular shape as described above, the rigidity of the building panel A is enhanced and the strength is improved, and the surplus gas component of the core material 3 and the core material 3 made of synthetic resin foam are used. The purpose is to prevent deformation of the surface material 1 due to aging. Furthermore, by forming the decorative surface in an uneven shape, the decorative surface is given a deep (shaded) and solid appearance, and wipes off a cheap image of metal. More specifically, the keystone-like makeup surface 6
Forms an inwardly projecting pot 6c between the recess bottom surface 6a and the recess side surface 6b. When the building panels A are connected to each other as shown in FIG. By forming the gap 12a so as to be indistinguishable, the gap between the decorative joint and the joint joint is formed so as to be indistinguishable. The depth of the pot 6a is ΔD and the height is Δ
T, the depth of the insertion groove 12 is Δd, and the height of the gap 12a is Δt.
Then, the relations are Δd ≧ ΔD and ΔT ≧ Δt. The above description is only one embodiment of the building panel according to the present invention, and FIGS. 3 (a) to (d) to FIG.
It can also be formed as shown in (a) to (f). 4 (a) to 4 (g) to 5 (a) to
(G) is sectional drawing which shows the other example of the panel A for a building. 6 (a) to 6 (k) to 8 (a)
(K) shows another embodiment of the keystone-like decorative surface 6. Of course, the construction panel A having only the surface material 1 may be used. As described above, according to the architectural panel of the present invention, the bonding strength between the surface material and the core material is greatly improved, and the surface material and the core material can be separated after production. Absent. Also, because the surface material was formed in a keystone tone (wavy shape),
Strengthens the rigidity of building panels to increase strength. When the core material is a synthetic resin foam, the surface material is prevented from being deformed by an excess gas component. In the case where the core material is a synthetic resin foam, deformation due to aging is prevented. Deep on makeup (shadow)
Gives a solid, solid look and wipes away the cheesy image of metal. Due to the formation of the pot, it is not possible to distinguish between the joints and the joints. There are features and effects.
