Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a siding board (hereinafter simply referred to as a board) that forms a horizontal wall or a vertical wall of an interior or exterior of a building or structure. be.

In particular, it relates to a board with enhanced waterproofness at vertical joints in horizontal walls.

[Conventional technology]

This type of board, which has been conventionally used, has a surface material such as colored steel plate, a core material made of synthetic resin foam (e.g. polyurethane foam, polyisocyanurate foam, etc.), and a sheet-like board due to its insulation properties, weight reduction, and ease of construction. A large number of boards are fabricated by sandwiching a backing material made of material and forming male and female connecting portions on both longitudinal edges of the facing material. Further, when a wall body, especially a horizontal wall body, is formed using this type of board, the vertical joints formed by butting the boards together in the longitudinal direction are waterproofed using caulking material.

[Problem that the invention seeks to solve]

However, this type of board has the disadvantage that the surface material is not sufficiently reinforced at the end surface in the short direction, that is, the end surface, and is easily deformed. In addition, when caulking the vertical joints of a horizontally clad wall, the caulking material is only bonded to the edge of the surface material in a small area, and the caulking material is in contact with the synthetic resin foam. This part makes almost no contribution to the adhesive strength. As a result, the caulking material only has a slight adhesion to the end surface of the surface material, and is easily damaged or detached by external force or weather-resistant deterioration.It also requires skill to perform the filling process, and is difficult to maintain a beautiful appearance. This has the disadvantage that it takes a long time to construct and cannot maintain its waterproof properties for a long period of time.

[Means to solve problems]

In order to eliminate the above-mentioned drawbacks, the present invention includes forming an end wall by bending inward at least one of the side edges of the decorative surface portion of the male and female connecting portions in the short direction, and attaching the board. It makes it easy and beautiful to form vertical joints, and it makes it extremely easy to install caulking material on vertical joints, in a short time, with a beautiful finished surface, and with sufficient adhesive strength. , and the part of the core material that is not covered by the end wall protrudes outward on the end surface, so that when the boards are butted together, the cushioning properties of the core material provide airtightness and strengthen the waterproofness of the board. This is a proposal.

〔Example〕

Hereinafter, typical embodiments of the board according to the present invention will be described in detail with reference to the drawings. That is, FIG. 1 is a perspective view showing the above-mentioned board A, and includes, for example, a surface-treated steel sheet, a zinc-nickel alloy plated steel sheet, an aluminum-zinc alloy plated steel sheet (trade name: Galfan, Galvalume steel sheet, Super Zinc), an aluminum sheet, an aluminum sheet. A surface material made of metal plates (including flat plates and embossed plates) made of one type of alloy plate, copper plate, clad steel plate, vibration-damping steel plate, etc., or a synthetic resin plate formed by one type of roll, press, or extrusion molding. The core material 18 is formed into a sandwich-like structure including a top layer, a core material 18 filled in the back surface on the surface material, and a sheet-like back material 19 covering the back surface of the core material 18.

That is, the surface material is composed of a decorative surface section, a male connecting section, and a female connecting section (2). Further explaining the board A shown in FIG. 1, when the board A is installed horizontally on both sides of the decorative surface section 1, inclined side walls 3 and side walls 4 are provided to create a three-dimensional effect and design. ,
The decorative surface portion mainly has a wide decorative groove 5 having a substantially triangular cross section. The male type connecting part has an insertion edge 7 that projects the tip of the inclined side wall 3 outward, and the tip of the insertion edge 7 is bent inward and then bent outward to make the cross section almost U-shaped. The engagement groove 8 is formed of an engagement groove 8, an extension part 10 that projects outward from the lower edge 9 of the engagement groove 8, and a tongue piece 11 that is bent into a flap shape at the tip of the extension part 10 as necessary. It is something. To explain further, a reinforcing lip (pipe-shaped in the figure) 7a is formed at the tip of the insertion edge 7 in parallel to the longitudinal direction of the board A. This insertion edge 7 fits into a fitting groove 15 described later,
Furthermore, the lower edge 14 of the fitting groove 15 is inserted into the engaging groove 8 to make the connection structure of the board A double, thereby improving the engaging force, waterproofness, and airtightness. Further, the reinforcing ribs 7a are intended to reflect rain within the connecting portion of the board A, thereby further strengthening waterproofness. The tongue piece 11 prevents the tip of the extension part 10 from waving and also prevents injuries caused by the end of the extension part 10 during operation. Note that the tongue piece 11 can be formed in an upper flap shape to hold one end of the backing material 19 as shown in FIG. 1, or it can be formed in a lower flap shape (not shown). The female connecting portion U has a fitting groove 15 formed by bending the lower end of the side wall 4 inward to form an upper edge 13, and bending the tip of the upper edge 13 outward to form a lower edge 14, and having a U-shaped cross section; The tip of the lower edge 14 is formed from a tongue piece 16 bent into a seam shape. To explain further, the lower edge 14 is inserted into the engagement 'a8 when the insertion edge 7 is fitted/fitted to #15, making the connection structure of the board A double, increasing the engagement force and waterproofing. It helps to strengthen the. Note that, like the tongue piece 11, the tongue piece 16 can be formed in an upper rib shape or a lower rib shape. Reference numeral 17 denotes an end wall, which is formed by bending at least one of the side ends of the decorative surface section 1 in the short direction vertically or at an arbitrary angle, for example, about 30 to 15.0 inches.
7 is reinforcement to prevent the decorative surface part l from warping, twisting, and front sagging, and the board A as shown in FIGS.
At the vertical joints formed by horizontally applying caulking material 2
It functions as an adhesive surface for bonding to the board A, and also serves to protect the core material 18, which will be described later, by blocking the infiltration of rainwater, heat, and sunlight from the end surface side of the board A. To explain further, the end wall 17 prevents the end of the board A from deforming, thereby making the edge of the board A straight, improving the aesthetics, and improving the vertical joints as shown in Figure 4 (al). By increasing the effective adhesion area with the caulking material 20 at α, the waterproofing and banking ability of the caulking material 20 can be fully demonstrated, and the peeling of the caulking material 20 due to vibration etc. can be prevented. Note that the end wall 17 is formed so as not to interfere with the connection of the male and female connecting parts, and At least fill the gutter-like part surrounded by the upper female connecting part and mainly board A.
It is a material that provides heat insulation properties to the material, and has secondary functions such as adhesive, noncombustible material, cushioning material, and soundproofing material, and is mainly made of synthetic resin foam. That is, the core material 18 is a resin for polyurethane foam, a resin for phenol foam, a resin for polyisocyanurate foam,
and flame retardants, flame retardant aids (borax, sodium metaborate, antimony dioxide, calcium carbonate, aluminum hydroxide), bentonite, perlite grains, shirasu balloons, etc. be. Further, the core material 18 is made of one type of material, such as a raw material that is discharged, molded, hardened, and self-adhesive, or a 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 19. To explain further, the core material 18 forms a protrusion 18a that protrudes outward from the end wall 17, as shown in FIG. 2, which is a cross-sectional view of FIG. This protruding portion 18a is formed by forming a vertical joint α formed by butting the boards A together in the longitudinal direction as shown in FIGS. ′, the gap between the eight boards or the paving board and the board A is closed using the cushioning properties of the core material 18,
This strengthens the sealing properties of the vertical joints α, α, and maintains waterproof properties even if the caulking material 20 deteriorates. Also, the protrusion 1
8a serves as a bank-up material when installing the caulking material 20, and the amount of caulking material 20 used can be reduced. The backing material 19 covers at least the backside of the core material 18 to make 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, and a backing material. For example, asbestos paper, kraft paper, asphalt felt, metal foil (8A, F
e, Pb, Cu), synthetic resin sheet, rubber sheet, cloth sheet, plaster paper, aluminum hydroxide paper, glass fiber nonwoven fabric, etc., or a laminate of one or more of them, or one that has been treated with waterproofing or flame retardant treatment. It consists of sheets etc.

Next, a construction example will be briefly explained. Now, assume that board A as shown in Fig. 1 is laid horizontally as shown in Figs. 3 and 4 (al) to form a wall. A thick color steel plate is used, the back material 19 is made of aluminum kraft paper, and the core material 18 is
In this example, a resol type raw material for phenol foam is discharged between the top surface material and the back surface material 19, reacted and foamed, and then cured and integrated. Therefore, the main pillars, studs,
The nth board A is attached to the wall base made of a waterproof sheet, etc. (the figure shows the wall base when no waterproof sheet is used).

When combined with the insertion edge 7 of the board A in the tier, as shown in FIG. 3, a joint portion rich in waterproofness, engagement force, backing property, and design is formed. In addition, in order to form the entire wall, it is sufficient to carry out the steps described above from the base toward the girder. Further, the vertical joint α shown in FIG. to be planted.

In this way, it is possible to form a wall that is highly waterproof.

〔Effect of the invention〕

As described above, according to the board A according to the present invention, (1) an end wall is formed on at least one side edge in the short direction of the decorative surface portion, so unevenness due to uneven distribution of the core material and residual strain due to molding of the surface material is prevented; There is no apparent warpage. ■There is no deformation caused by front sag when cutting the board. ■ Caulking of vertical joints becomes extremely easy and reliable. ■Since a protruding part made of a core material with cushioning properties is formed on the end surface of the board, it not only strengthens the waterproofness and sealing performance of the vertical joints when the board is installed horizontally, but also can be maintained for a long time. . ■Protrusions eliminate the need to use back-up material at vertical joints, making construction easier and reducing the amount of caulking material used.

■When the board is stretched vertically, it has good adhesion to the drain at the base, which prevents rainwater from blowing up due to the wind and penetrating into the board. ■Since the board has a sand inch structure, it has soundproofing, heat insulation, vibration proofing, fire resistance, condensation resistance,
and mechanical strength is significantly improved. ■Since the board can be made wider, it is easier to construct, and the width of the material can be used more effectively, making it more economical.

There are other effects.
