Description

[Detailed description of the invention] [Field of industrial application] The invention is useful for forming horizontal walls for the interior and exterior of buildings and structures with excellent waterproofness and design, as well as for forming terraced roofs. This invention relates to architectural panels (hereinafter simply referred to as panels). [Prior art] This type of panel that has been used in the past includes Japanese Patent Publication No. 51-29339, Utility Model Publication No. 51-11882,
There is Jikko No. 54-26649. however,
There were various problems with the above panel. In other words, when rainwater is blown by the wind on the panel (cladding board), the rainwater leaks to the back side because it is simply a connecting structure of flat plates, corroding the rim and pillars, and adding moisture to the room and closet. There was a drawback. In addition, because the length of the lower edge of the panel to the rising part is long, it is weak in tensile force, and has the disadvantage that only an exterior without joints can be formed. Furthermore, although the exterior was originally without joints, due to the skill of the builder, the exterior was made up of joints of varying widths, some without joints, some with joints, and there was a risk of injury at the rising parts during construction. In addition, the panel has a complicated side surface shape, making it difficult and expensive to mold.Furthermore, there are no reinforcing ribs on the flat part, so warping, twisting, etc. appear on the decorative surface, which spoils the aesthetic appearance. It was hot. In addition, since none of the panels have a backing material and the wall base and surface material are in direct contact, condensation forms on the back of the decorative surface, leading to rust and corrosion of the wall base, and the insulation of the wall itself. fire retardant,
It lacked soundproofing properties, failed to prevent deformation of the decorative surface, was prone to deformation of the panel itself, and lacked connection strength. Among this type of panels, panels having a drop-in type connection structure are also known, but these have the disadvantage of being inferior in waterproofness and workability. [Purpose of the invention] In order to eliminate the above-mentioned drawbacks, the present invention forms a wide panel with the decorative surface part shaped like a step, and also forms a depression at the lower end of the stepped piece of the stepped part of the decorative surface part to form a joint part. The appearance is very similar to that of
A groove is formed on the upper surface of the insertion edge of the male connecting part provided at one end of the decorative surface part to prevent rain from returning to the connection part and to prevent capillary action. A caulking material is planted on the top surface of the reinforcing rib provided at the tip to further improve waterproofness, and the adhesiveness of only the surface layer of the caulking material is removed using heat, powder, organic solvent, etc., making the panel easier to handle. In addition, a reinforcing piece bent downward is formed at the tip of the extension to serve as a guide when filling the core material or to prevent material leakage, and can be easily installed by one worker. Furthermore, we propose a panel that can be used without requiring any skill. [Structure of the invention] The structure of the panel according to the invention will be described below with reference to the drawings. That is, as shown in FIG. 1, the above-mentioned panel A is made of, for example, a surface-treated steel sheet, a steel sheet plated with a zinc-nickel alloy, a steel sheet plated with an aluminum-zinc alloy (trade name: Gulfuan, Galvalume Steel Sheet, Super Zinc), an aluminum sheet,
Metal plates (including flat plates and embossed plates) made of one type of aluminum alloy plate, copper plate, clad steel plate, vibration damping steel plate, etc., or synthetic resin plates are formed by rolls or presses, or by extrusion molding. A core material 18 is integrally filled between a surface material 1 and a back material 20 formed of seeds to form a sandwich structure. To explain further, the surface material 1
As shown in the figure, it is composed of an elongated decorative surface part 2 , a male type connecting part 4 , and a female type connecting part 12 . That is, the decorative surface portion 2 is formed by forming at least one step at an arbitrary position (approximately the center in the figure) on the surface of the elongated plate material, as shown in the figure, parallel to the longitudinal direction of the surface. It is composed of a plurality of long oblique decorative pieces (hereinafter simply referred to as decorative pieces) 2a and 2b that are divided into sections. To explain further, the step part 3 is made by bending the step pieces 3a and the lower ends of the step pieces 3a inward at an angle θ ₁ with respect to the horizontal line (a line parallel to the line of the base when panel A is installed), and then Fold outwards to a depth of, for example, 1 to 10
It is formed from a recessed portion 3b having a diameter of about mm.
The size of the recess 3b is the size of the gap that occurs when the surface material 1 is bent, or it is formed arbitrarily, so that the lower end of the stepped piece 3a and the decorative piece 2b are clearly separated, and the panel A is By making the appearance of the joint part and the step part 3 closely similar when constructed, the appearance is made as if a wall body was formed from the individual panels of the decorative pieces 2a and 2b, and the aesthetics are improved. Also, the step part 3 is panel A.
In addition to improving the design of the panel A, the strength of the panel A is also improved, and even if the panel A is formed to have a wide width, it is useful for preventing warping, twisting, and twisting. The male connecting part 4 includes an insertion edge 5 provided by protruding outward from one end edge of the decorative surface part 2 , an engagement groove 8 with the insertion edge 5 as the upper edge, and a lower edge 9 of the engagement groove 8. It is formed from an outwardly protruding extension part 10 and a reinforcing piece 11 which is bent downward at the tip of the extension part 10. Furthermore, a groove 6 provided along the longitudinal direction of the panel A and a reinforcing rib (pipe-shaped in the figure) 7 provided at the tip thereof are formed midway on the upper surface of the insertion edge 5. To explain further, the insertion edge 5 fits into a fitting groove 16 of a female connecting part 12 which will be described later, and the engagement groove 8 is used to insert the lower edge 15 of the fitting groove 16 into the panel A. The connection structure is double-layered to improve engagement force, waterproofness, and airtightness. Further, the groove portion 6 prevents rain return and capillary phenomenon at the connecting portion of the panel A, improves the waterproofness of the connecting portion, and functions as a guide for installing caulking material 21, which will be described later. Furthermore, the reinforcing piece 11 prevents the tip of the extension part 10 from waving, and also serves as a guide when a molded body is used as the core material 18, which will be described later. When used, it helps prevent liquid leakage from the edge of the male connector 4 . Furthermore, since the reinforcing piece 11 reinforces the strength of the end of the extension part 10, it also has the effect of preventing deformation of the extension part 10 during nailing. Although not shown, the reinforcing piece 11
It is also possible to form a furrow-like tongue at the tip. The female connecting part 12 includes a step piece 13 which is bent inward at the other end of the decorative surface part 2 , a step piece 13 whose lower end is bent inward to form an upper edge 14, and then bent outward to form a lower edge 15. The fitting groove 16 is formed from the edge 14 and the lower edge 15 into a substantially U-shaped cross section, and a tongue piece 17 is formed by bending the tip of the lower edge 15 into a seam shape. It is inserted into the engagement groove 8 when the insertion edge 5 is fitted into the engagement groove 16, and serves to further strengthen the engagement force. For convenience, the core material 18 includes an upper portion 18a disposed in a gutter-like portion surrounded by the decorative surface portion 2 , the male connecting portion 4 , and the female connecting portion 12 , and a bulging portion 18b bulging downward from the extension portion 10. and a notch 19 is provided near the female connecting portion 12 . This core material 18 mainly provides heat insulation properties to the panel A, and is made of one type of material having secondary functions such as an adhesive, a noncombustible material, a cushion material, and a soundproof material. Specifically, it is made of synthetic resin foam, rock wool, glass wool, sheathing board, gypsum board, wood wool cement board, etc., and the raw materials are discharged, molded, hardened,
It is made of one type of material, such as self-adhesive material or a molded product. Note that when a molded body is used, an adhesive (not shown) is required between the core material 18, the surface material 1 , and the back material 20. To explain further, as shown in FIG. 4, the bulging portion 18b of the core material 18 prevents the surface material 1 from coming into contact with the wall base α when the panels A are connected, and prevents the surface material 1 from contacting the wall base α. This helps prevent thermal bridges and improves insulation. Furthermore, since the bulging portion 18b is also disposed at the bottom of the joint, which is a weak point in terms of fire protection, panel A can further improve fire protection and pass the fire protection structure test and quasi-noncombustibility test. In addition, core material 1
When a material with cushioning properties is used as the material 8, it has the characteristic of preventing the vibration of the wall base from being transmitted to the connecting part and preventing the connecting part from coming off. In addition,
The core material 18 is mainly made of synthetic resin foam, such as resin for polyurethane foam, resin for phenol foam, resin for polyisocyanurate foam, and flame retardants and flame retardant aids (borax, borax, etc.).
A material containing one or more of sodium metaborate, antimony trioxide, calcium carbonate, aluminum hydroxide), bentonite, pearlite particles, and shirasu balloons is used. In addition, the notch 19 extends near the female connecting portion 12 at a distance from the innermost part of the engagement groove 8 to the edge of the male connecting portion 4 of panel A.
It is cut out in a substantially square shape over a distance W ₂ that is greater than W ₁ . In particular, when W ₁ and W ₂ are made the same, the back side of Panel A will be flat when installed, and since it will cover the entire wall base, Panel A will have better heat insulation and fire prevention properties. I can do it. Reference numeral 20 is a back material that covers at least the back surface of the core material 18 to make the panel A a sandwich structure, which improves the mechanical strength of the panel A itself, as well as a noncombustible sheet, a waterproof membrane, a heat shield sheet, a water absorbing sheet, a soundproof sheet, and packing. It is useful as a material such as asbestos paper, kraft paper, asphalt felt, metal foil (Al, Fe, Pb, Cu),
1. Synthetic resin sheets, rubber sheets, cloth sheets, gypsum paper, aluminum hydroxide paper, glass fiber non-woven fabrics, etc.
It is made of seeds, a laminate of two or more kinds, or a sheet that has been treated with waterproofing or flame retardant treatment. Reference numeral 21 denotes a caulking material, which is planted in the form of a band or string on the upper surface of the insertion edge 5 in parallel to the longitudinal direction of the panel A.
This is to improve the waterproofness, packing and sealing properties of the joints. The material of this caulking material 21 is, for example, hot melt type, silicone type,
Polyurethane-based, acrylic-based, SBR-based, etc., as well as acrylic super absorbent resins that expand when water is absorbed and contract when dry, borax, metaborate soda, etc. that foam and harden by releasing crystal water under high heat. It is made of one of the blended materials and has elasticity and adhesiveness, and only the adhesiveness of the surface layer has been removed. That is, the adhesiveness of the surface layer is removed by applying heat to the caulking material 21 for a short time, wiping the surface with an organic solvent such as alcohol or a mold release agent, or coating the surface of the caulking material 21 with non-adhesive powder. do. This is to prevent the caulking material 21 from adhering to other members, hands, etc. during work or manufacturing, making handling easier. Further, the caulking material 21 is applied to the fitting groove 16 of the upper panel A at the connection part of the panel A as shown in FIG.
Partially glue the insertion edge 5 and the upper edge 14 inside,
This significantly improves the sealing performance of the joint, prevents air from flowing inside and outside the wall, and greatly improves waterproofness and packing performance. That is, when connecting panels A as shown in FIG.
1 is deformed and the surface area becomes larger, the sticky interior appears on the surface and adheres the adjacent panels A, greatly improving the waterproofness and sealing performance of the connecting part. Furthermore, since the caulking material 21 is disposed above the insertion edge 5, it prevents rainwater from penetrating into the fitting groove 16, as shown in FIG. It is useful to prevent Further, the concrete planting position of the caulking material 21 is, for example, the position shown in FIGS. That is, figures a to e show the caulking material 21 planted in a part of the groove 6, and figure a shows the caulking material 21 planted in a part of the groove 6.

This is a W ₂ relationship. This is to form the step of the decorative surface part 2 and the step of the horizontal joint part to have almost the same appearance when panel A is installed on the wall base α as shown in Fig. 4. This is to create a unified horizontal line and improve aesthetics. [Construction Example] Now, it is assumed that the panel A shown in FIG. 1 is laid horizontally as shown in FIG. 4 to form a wall. In addition, for panels A ₁ and A ₂ , a 0.27-thick color steel plate is used as the surface material 1 , aluminum kraft paper is used as the back material 20, and the core material 18 is made of the surface material 1 and the back material 20.
During this process, raw materials for polyisocyanurate foam are discharged, reacted and foamed, and then cured and integrated.The caulking material 21 is a hot melt type, and the surface is made sticky with a release agent. The removed material was used and planted on the reinforcing rib 7 side of the groove 6.
Therefore, the extension part 10 of the nth panel A ₁ is attached to the wall base consisting of main pillars, studs, waterproof sheets, etc. (the figure shows the wall base when no waterproof sheets are used) α.

Of course, the panel A may be a combination of each of FIGS. 3a to 3g and FIGS. 5a to 8a to 8a. [Effects of the invention] As mentioned above, according to the panel according to the invention,
Because at least one level difference is formed on the decorative surface, the strength is sufficiently reinforced to prevent warping, twisting, and
It is possible to prevent flattening and prevent the decorative surface from becoming mountain-like. Since the male and female joints have the above-mentioned drop-in structure, it can be easily constructed by one person, the joint width (horizontal) can be kept constant, and it is highly waterproof. Since a depression is formed in the step, the shape closely resembles the joint, creating a unified horizontal line on the wall, giving the wall a three-dimensional feel and improving its aesthetics. . Since the panels have a sandwich structure, soundproofing, heat insulation, vibration proofing, fire resistance, condensation resistance, and mechanical strength are greatly improved. Since the core material is also placed on the back side of the extension, it prevents the surface material from forming a thermal bridge, greatly improving the heat insulation, and improving the fire protection of the joint, which is a weak point in terms of fire protection.
Since grooves and reinforcing ribs are formed on the upper side of the insertion edge, the waterproofness of the panel connection area is improved. Since a reinforcing piece is formed on the edge of the extension, it serves as a guide when the molded body is used as a core material. If a material that is discharged in liquid form, reacts, foams, and hardens is used as the core material, the reinforcing piece can prevent liquid leakage from the male connector side. The strength of the extension is reinforced by the reinforcing piece, so there is no deformation due to nailing.
Since the caulking material bonds between the panels, waterproofing and sealing properties are greatly improved. Since the surface of the caulking material has no adhesive properties, the panel can be easily handled without adhering to other members. Since the caulking material is placed above the insertion edge, rainwater will not enter the fitting groove and will not accumulate in the fitting groove. Since the panel can be made wide, it is easy to construct, and the width of the material can be used effectively, making it highly economical. There are other effects.
