Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to siding boards (hereinafter simply referred to as boards) that are used to form vertically or horizontally stretched walls as exterior or interior materials for buildings and structures. It is something. More specifically, the present invention relates to a board that has an unprecedented design and is excellent in heat insulation, fireproofing, waterproofing, airtightness, engagement force, and strength.

[Conventional technology]

Conventionally, a thin metal plate is used as the surface material, male and female connecting parts are formed on both longitudinal edges, and synthetic resin foam is used on the back side of the surface material.
Many boards with laminated backing materials are covered. In this type of board, a core material is formed to bulge out on the lower surface of the nailing crotch in order to strengthen the waterproofness and heat insulation of the joint.

[Problem that the invention seeks to solve]

However, when forming an exterior wall with this type of board, since there is a core material such as synthetic resin foam on the bottom surface of the nailing piece, it is necessary to use a resilient core material such as synthetic resin foam. In some cases, when nailing, the elasticity of the core material caused the nailing pieces to bulge out, making nailing difficult. In addition, nailing destroys the nailing piece and the core material that bulges out on the underside of the nailing piece, resulting in dimensional differences in the joints and a decrease in waterproofness due to a decrease in engagement force.
This resulted in a decrease in heat insulation and airtightness.

Furthermore, this type of board lacks the strength of the insertion edge, the connection between the insertion edge and the fitting groove is not shaped to prevent capillary action, and the decorative surface lacks design. there were. In addition, using the same board vertically and horizontally has the disadvantage of poor workability and waterproof properties.

Measures to Solve Problem c] In order to eliminate these drawbacks, the present invention provides one or more special decorative grooves on the decorative surface, and also strengthens and reinforces the insertion edge and lower edge to make them waterproof. We propose a board that is easy to install, has a shape that provides design, engagement strength, and can be used both vertically and horizontally.

〔Example〕

An embodiment of the board according to the present invention will be described in detail below with reference to the drawings. That is, FIG. 1 is a perspective view showing the board A, in which the upper part is the surface material, 20 is the core material, and 21

It is made into a sandwich. To explain further, on the surface material, for example, surface treated steel plate, fluorine coated steel plate,
Zinc/nickel alloy plated steel plate 1, aluminum/zinc alloy plated steel plate (product name Galfan, Galvalume steel plate, Super Zinc), aluminum plate, aluminum alloy plate,
The material is one type of metal plate (including flat plate and embossed plate) such as steel plate, clad steel plate, and damping steel plate.

Note that the material for the surface material also includes flat plates, embossed plates, ricin-coated plates, and enameled plates. Also,
For surface materials, molding rolls, presses, extrusion, injection molding,
It is formed into a predetermined shape by one means such as drawing, and an example of the specific shape will be explained using FIG. 2.The surface material has a decorative surface part -? It is composed of =, male type connecting part ↓, and female type connecting part. To explain further, the decorative surface part I is formed from at least one decorative groove 3 formed along the longitudinal direction on the surface material, and decorative pieces 2a and 2b divided into a plurality of parts by the decorative groove 3. Furthermore, at least one decorative groove 3 is provided in the decorative surface portion I, which strengthens the strength of the board A and improves the strength of the board A.
Even if it is formed into a wide width, it is useful to prevent warping, twisting, and flatness, and to make the decorative surface part flat board A. , which improves the design of the wall. The male connecting portion has a side wall 5 with one end of the decorative surface portion l bent inward;
An insertion edge 8 consisting of an upper surface 6 whose end edge is extended almost parallel to the decorative pieces 2a and 2b, and a lower surface 7 whose tip is folded inward and extended inward, and the tip of the lower surface 7 is folded back outward. The locking groove 9 is formed by extending horizontally as it is, the extension part 11 is formed by extending the lower edge 10 of the engagement groove 9 outward, and the tongue piece 12 is formed by bending the tip of the extension part 11. be. In particular, a chamfered surface 8a is formed at the end between the upper surface 6 and the lower surface 7 to provide waterproofness or serve as a region for filling an engagement groove 8 (not shown) with caulking material. Female connection part U
The other end of the decorative surface portion is bent inward to form a side wall 14, the lower end thereof is bent inward to form an upper edge 15, the tip of the upper edge 15 is bent outward to form a lower edge 16, and an upper edge 15. and a lower edge 16, a fitting groove 17 formed in a U-shaped cross section, and a core material holding piece 18 provided at the tip of the lower edge 16. Moreover, 19 is a recessed part for filling the core material 20. To explain further, the fitting groove 17 is for fitting the insertion edge 8, and since it is exposed externally at the base part especially in horizontal mounting, it should be located at the same level as the side wall 14 or inward from it. is preferred. In addition, the core material holding piece 18 is attached to the lower edge 16
The tip is bent inward in an oval shape in cross section, and functions for filling the core material 20, holding the back material 21, and reinforcing it when engaged, and one end edge of the back material 21 is connected to the core material. It is located inside the clamping piece 18 to prevent liquid from leaking when the core material 21 is discharged as a raw material like a synthetic resin foam. The core material 20 fills at least the decorative surface part on the back side of the surface material, the male connecting part soil, and the recessed part 19 surrounded by the female connecting part U, and mainly provides heat insulation to the board A. It is made of one or more materials that have secondary functions such as adhesives, noncombustible materials, cushioning materials, and soundproofing materials. Specifically, it is made of one type of synthetic resin foam, such as polyurethane foam, polyisocyanurate foam, phenol foam, epoxy foam, polyethylene foam, polystyrene foam, etc.
Both the raw material and the molded product can be integrated. The backing material 21 covers at least the backside of the core material 20 to give the board A a sandwich structure, and improves the mechanical strength of the board A itself, as well as a noncombustible sheet, a waterproof membrane, a heat shielding sheet, a water absorbing sheet, a soundproofing sheet, a backing material, etc. For example, asbestos paper, kraft paper, asphalt felt, metal plate, metal foil (AR,
