Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is applicable to buildings and structures that are excellent in waterproofness and design.
The present invention relates to an architectural panel (hereinafter simply referred to as a panel) that is useful for forming horizontal exterior walls and, by extension, a stepped roof.

[Conventional technology]

Conventionally used panels of this type include ■Special Publication No. 51-29339, ■Utility Publication No. 51-11882, and O.
There are examples such as Utility Model Publication No. 54-26649. however,
There were various problems with the above panel. That is,
When rainwater is blown by the wind on the panel (closing board) shown in ■, the rainwater leaks to the back side because it is simply a connecting structure between flat plates, corroding the rim and pillars, and adding moisture to the room and closet. There were drawbacks.

In addition, the panel (■) has a long length from the sloped part of the lower edge to the rising part, so it is weak in tensile force and has the disadvantage that only an exterior without joints can be formed. Moreover, although the exterior was originally without joints, depending on 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 damage at the rising parts during construction. In addition, this 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 and spoil the aesthetic appearance. was there. 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. It lacks fireproofing and soundproofing properties, cannot prevent the decorative surface from deforming, and has the drawbacks that the panel itself is easily deformed and lacks 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 makes the decorative surface part step-like and forms the panel with a wide width, and also makes the step of the decorative surface part and the step of the connecting part look very similar to each other. A groove is formed on the upper surface of the insertion edge of the male connector to prevent rain from returning to the connection and to prevent capillary action, and the upper surface of a reinforcing rib is provided at a portion of the groove or at the tip of the insertion edge. Caulking material is planted on the nail to improve waterproofness, and the tongue piece provided at the tip of the nailing piece is tilted upward and bent to greatly improve backing performance and connection strength. Moreover, the present invention proposes a panel that can be easily constructed by one worker without requiring any skill.

[Structure of the invention]

Below, the structure of the panel according to the present invention will be explained using 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 coated with a zinc-nickel alloy, an aluminum-zinc alloy plated steel sheet (trade name: Golf 1, Galvalume Steel Sheet, Super Zinc),
A metal plate made of one type of aluminum plate, aluminum alloy plate, copper plate, etc. (including flat plates and embossed plates), or a synthetic resin plate formed by roll or press, or one type of extrusion molding. A core material 18 is integrally filled between the top surface material and the back surface material 20 to form a sandwich structure. To explain further, as shown in FIG. 2, the top of the surface material is composed of an elongated decorative surface part, a male type connecting part soil, and a female type connecting part U. In other words, the main part of the decorative surface is placed at an arbitrary position on the surface of the elongated plate (approximately at the center in the figure) parallel to the longitudinal direction of the surface, as shown in the figure.
It is composed of a step piece 3 forming at least one step and a plurality of long inclined decorative pieces (hereinafter simply referred to as decorative pieces) 2a and 2b separated by the step piece 3. This stepped piece 3 not only improves the design of the panel A, but also improves the strength of the panel A, and is useful for preventing warpage, flatness, and twisting.

In addition, the male connecting portion has an insertion edge 5 with the upper end of the decorative surface portion 1 protruding outward, an engagement groove 8 with the insertion edge 5 as the upper edge, and an engagement groove 8 with the insertion edge 5 as the upper edge. It is formed from a nailing piece 10 whose lower edge 9 projects outward, and a tongue piece 11 provided at the tip of the nailing piece 1o. To explain further, a groove 6 provided along the longitudinal direction of the panel A and a reinforcing lip (pipe-shaped in the figure) 7 provided at the tip thereof are formed in the middle of the upper surface of the insertion edge 5, as will be described later. It fits into the fitting groove 16 of the female type connecting part (2). 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 also functions as a groove for planting a conical material 21 to be described later. Furthermore, the tongue piece 11 is formed at the tip of the nailing piece lO in the shape of an upper seam as shown in the figure, or in the form of a lower seam (not shown), and is bent upward, as shown in FIG. As shown in the figure, the connecting part bites into and presses the back surface of the core material 18 of the upper panel A, improving the adhesion between the engagement groove 8 and the lower edge 15 of the fitting part 16, and improving the backing properties of the connecting part. , which is useful for improving the connection force. The female connecting part U has a step piece 13 whose lower end on the decorative surface part is bent inward, the lower end thereof 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 upper edge 14 and the lower edge 15 and has 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. is inserted into the retaining groove 8 when the insertion edge 5 is fitted into the fitting groove 16, and serves to further strengthen the engagement force. The core material 18 is filled in the back surface of the decorative surface part 1, and is also filled in the back surface of the nail driving piece 10, and a cutout part 19 is provided near the female type connecting part. This core material 18 mainly provides heat insulation properties to the panel A, and is made of one type of material that has secondary functions such as an adhesive, a noncombustible material, a cushioning material, and a soundproofing material. Specifically, synthetic resin foam,
It is made of rock wool, glass wool, sheathing board, gypsum board, wood wool cement board, etc., and is made of raw materials that are discharged, molded, hardened, and self-adhesive, or it is made of one type of molded product.

In addition, when using a molded body, an adhesive (not shown) is required between the core material 18, the surface material, and the back material 20.

To explain further, when the panels A are connected, the core material 18 prevents the top of the surface material from coming into contact with the wall base α, and prevents the top of the surface material from forming a thermal bridge. This is useful for preventing heat loss and improving insulation properties. Furthermore, core material 18
Since panel A is also placed 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-noncombustible test. When a material with cushioning properties is used, it has the characteristic of preventing vibrations from the wall base from being transmitted to the connecting parts and preventing the connecting parts from coming off. 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, sodium metaborate). , antimony dioxide, calcium carbonate, aluminum hydroxide), bentonite, pearlite grains, and shirasu balloons. In addition, the notch 19 is cut into a substantially square shape near the female connecting part 2 over a distance Ws that is greater than the distance W1 from the innermost part of the engagement groove 8 to the edge of the male connecting part soil of panel A. It is something that is missing. Especially Vl/+ and W
When l is made the same, the back surface of panel A becomes flat when constructed, and the wall base is completely covered, so panel A can have better heat insulation and fire prevention properties.

Reference numeral 20 is a backing material that covers at least the backside of the core material 18 to make the panel A a sandwich structure, improving the mechanical strength of the panel A itself, and also improving the mechanical strength of the panel A itself. It is useful as a material such as asbestos paper, kraft paper, asphalt felt, metal foil (A It % F
es Pb5Cu), synthetic resin sheet, rubber sheet,
It is made of a laminate of one or more of cloth sheets, gypsum paper, aluminum hydroxide paper, glass fiber nonwoven fabric, etc., 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, and is used to provide waterproofness, backing properties, and sealing of the connection part of the panel A. It is intended to improve sexual performance. In addition, the material of the caulking material 21 is mainly hot melt type, rubber type,
Soft foam type, urethane type, or acrylic super absorbent resin that expands when water is absorbed and contracts when dry, borax, sodium metaborate, etc. that foams and hardens by releasing crystal water under high heat, etc. Alternatively, it may be made of one or more adhesive tapes. Furthermore, caulking material 2
The specific planting position of No. 1 is shown in Fig. 3 (a) to (g), for example.

That is, (a) to (81) show the caulking material 21 planted in a part of the groove 6, (a) shows the caulking material 21 planted on the reinforcing rib 7 side of the groove 6, and (b) shows the caulking material 21 planted in a part of the groove 6. 6, the caulking material 21 is planted on the side of the decorative piece 2a of FIG. The caulking material 21 is also planted on the boundary between the insertion edge 5 and the decorative piece 2a in the figure (e), and the caulking material 21 is planted on the upper side of the reinforcing rib 6 in the figure (f). The material 21 (g) shows the caulking material 21 planted on the boundary between the insertion edge 5 and the decorative piece 2a. Note that the caulking material 21 is planted so as not to impede the function of the groove portion 6 described above. As shown in FIG. 4, this caulking material 21 is in close contact with the upper edge 14 in the fitting groove 16 of the upper panel A at the joint part of the panel A, greatly improving the sealing performance of the joint part, and This prevents the circulation of air between the inside and outside of the bag, greatly improving its waterproof and backing properties.

Here, the dimensions and angles of each part of panel A will be explained as follows. That is, as shown in FIGS. 1 and 2, the height of the step piece 3.13 is hash, and the height of the step piece 3.13 is hash.

This is so that when panel A is installed on the wall base α as shown in Figure 4, the step of the decorative surface part l and the step of the horizontal joint part will be formed to have almost the same appearance, and the wall formed by panel 8 will have the same appearance. This is to create a unified horizontal line and improve aesthetics.

[Construction example]

Now, assume 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+ and As, a 0.27 mm thick color steel plate is used on the surface material, aluminum kraft paper is used for the back material 20, and polyisocyanate is used for the core material 18 between the surface material and the back material 20. The raw material for the Nurate foam was discharged, reacted, foamed, and then cured to be integrated. A hot melt type caulking material 21 was used, and it was implanted on the reinforcing lip 7 side of the groove 6. Therefore, the nailing piece 10 of the n-th panel A+ is attached to the wall base α consisting of main pillars, studs, waterproof sheets, etc. (the figure shows the wall base when no waterproof sheet is used) through the nails β. Fix it. Next, connect the fitting groove 16 for the female type connection part of the n+1st panel A2 to the male type connection part of panel A+ ↓
It is inserted into the insertion edge 5 of the holder to form a horizontal joint part as shown in FIG. Furthermore, in order to form the entire wall, the steps described above may be performed from the base toward the girder. Note that it is necessary to use a starter (not shown) for the base, and caulking material and accessories for the exit and entry corners (not shown). A similar process is also used to form the roof.
