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) useful for forming horizontal walls of buildings and structures.

[Conventional technology]

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

In addition, the board (■) 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 board has a complicated side 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, spoiling the aesthetic appearance. there were.

In addition, since all of the boards do not have a backing material, condensation forms on the back of the decorative surface, causing rust, and the wall itself lacks insulation, fireproofing, and soundproofing properties.In addition, the decorative surface cannot be prevented from deforming, and the board It has the disadvantage that it is easily deformed and lacks connecting force.

Furthermore, no matter which of the above-mentioned boards (1) to (0) are used, the connecting parts of the boards are often in direct contact with the underlying material, so condensation often corrodes the underlying material, and the Because the vibrations and deformation of the structure were directly transmitted, it had the disadvantage of being easily dislodged.

[Purpose of the invention]

In order to eliminate such drawbacks, the present invention forms the lower edge of the decorative surface in a U-shaped longitudinal section, and the longitudinal section along the longitudinal direction of the decorative surface is scalene trapezoidal. By forming at least one cosmetic groove with the same shape as the longitudinal section of the joint when forming the body, the joint becomes one unified pattern of the wall body, creating a beautiful appearance. An engaging part is provided for forming a joint as described above from the base part and the rib-like protrusion, and the decorative surface, the locking part, the slope part, the joint base part, and the outer surface of the protrusion. Insulating material is integrally filled in the concave area surrounded by and, and the insulating material is also placed on the back side of the engaging part, so that the decorative surface will not be flattened, deformed, warped, or twisted, and the board will not form a mountain. It is possible to construct a wall that has beautiful joints that have a three-dimensional effect, and has workability, waterproofness, corrosion resistance, heat insulation, fireproofing, cushioning, productivity, and vibration-proofing properties. Suggest a board that can.

[Structure of the invention]

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 above board, and the upper part is a surface material and a metal plate (flat plate, embossed plate).
, a synthetic resin plate is molded as shown in FIG. That is, on the surface material there are a decorative surface 2, a decorative groove 3, a locking part soil,
It is formed from an engaging part 1 and a fixing part 13. To explain further, 2 is a horizontally elongated decorative surface (hereinafter simply referred to as decorative surface), on which at least one decorative groove 3 is formed along the longitudinal direction. This decorative groove 3 is mainly used to prevent the decorative surface 2 from warping, twisting, and flattening, and to distinguish between the joints of the wall and the decorative groove 3 when the board is installed, and to unify the wall with one pattern. This not only gives it a beautiful appearance, but also helps create a sense of three-dimensionality despite its size. To explain further, the decorative groove 3 has a scalene trapezoidal vertical section as shown in FIG. top surface 3
b and a lower inclined surface 3c whose lower edge is inclined rearward upward at an angle θ2 (acute angle). The locking portion is formed by bending the lower end of the decorative surface 2 inward to form a substantially U-shaped longitudinal section. More specifically, as shown in FIG. 4, the locking part includes a decorative surface 2, a so-called horizontal bottom 5, a locking piece 6 that is almost perpendicular to the top, and a tip of the locking piece 6. The length of the bottom side 5 to the locking piece 6 is shortened to minimize the deformation of the locking part soil. In addition, the shading created by the right angle promotes the three-dimensional appearance of the joint, and the locking piece 6 makes contact with the engaging part 1 described later over a large area, and functions as a guide during construction, a stable support piece, and a waterproof surface. In addition, the tongue piece 7 is used to form a gap to prevent capillary phenomenon from occurring at the engagement portion with a protrusion 11 (described later), and to prevent the tip of the locking piece 6 from becoming sharp like a knife during construction. As shown in Fig. 5(a), middle), the engaging part work is performed by aligning the upper end of the decorative surface 2 at an angle θ corresponding to the angle θ2. '2, an inclined part 9 that slopes upward at the rear, a joint base part 10 whose edge is vertically extended upward, and a rib-shaped protrusion 11 that is inclined at an angle θ4 (acute angle) with respect to the surface of the joint base part 100. and an upper end wall 12 which protrudes by Δh by bending the outer tip of the protrusion 11 horizontally from the joint basement part 10 (Fig. (a)) or extending it as it is (Fig. (b)). Engagement of joint ground and anchoring soil f
131. To explain further, the slope part 9 improves the flow of rainwater, prevents rainwater from accumulating in the joint basement part 10, promotes a three-dimensional appearance when forming the joint, and increases the working width. It is something that will help you grow. Further, the joint base portion 10 consists of a vertical surface or a substantially vertical surface, and serves as a waterproof base for the joint portion and as a guide for the locking piece 6. Further, the protrusion 11 is connected to the locking piece 6
are engaged under a certain elasticity, and the capillary phenomenon between the locking piece 6 and the protrusion 11 is prevented by the rain return, reinforcement to prevent deformation on the surface material, and the shape of the triangular bent part 11a. In addition, by providing the upper end wall 12 with the lower edge of the outer surface 11b protruding from the lower end of the inner surface lie by Δh, the cutout portion 17 is It is useful to prevent it from getting bigger. Especially when the upper end wall 12 is horizontal (
In Figure (a), a flat plate material such as a steel belt can be used to convey the surface material, and the rotation speed can be much higher than that of a mold such as a caterpillar, which greatly improves productivity and reduces costs. This is also related to down.

Incidentally, it is preferable that the angle θ4 is such that only the surface in contact with the tongue piece 7 is inclined in order to strengthen the engagement force.

The specific angle θ4 is selected depending on dimensions such as the width W of the base 5 on the surface material having a height h. 13 is the fixed part, upper, d! ! The tip of No. 12 is extended vertically upward, and the No.
As shown in the figure, it is useful for fixing to the base (frame, studs, frame, base board) A via nails B. Reference numeral 14 denotes a tongue piece formed at the tip of the fixed part 13 as necessary, and is mainly used to prevent danger during construction and to prevent deformation such as waving of the fixed part. 16 is a heat insulating material and a recess 15
, the engaging part, and the back side of the fixing part 13, which mainly provide heat insulation to the board, and secondary materials such as core material, cushioning material, reinforcing material, adhesive, soundproofing material, and moisture proofing material. It functions as a material and rust preventive material. Its shape corresponds to the recess 15, and the end near the locking part is cut so that a gap of approximately triangular or rectangular shape (not shown) is formed between the bottom side 5 and the locking piece 6. It is formed so that a notch 17 is provided. To explain further, since the heat insulating material 16 is provided to the back side of the fixed part 13, it alleviates the vibration of the base, prevents the connection part from coming apart due to earthquakes, etc., and also prevents the surface material from forming a thermal bridge. This provides the board with four functions: preventing heat loss and further improving heat insulation. The material of the heat insulating material 16 is one of synthetic resin foam, rock wool, glass wool, sheathing board, gypsum board, wood wool cement board, etc.
It consists of one type of material, such as a material that is discharged, molded, hardened, and self-adhesive, or a molded product. In addition, when using a molded body, it is necessary to use an adhesive (not shown) on the surface material and between the back surface material 18 and the heat insulating material 16. To explain further, the heat insulating material 16 is mainly made of synthetic resin foam, such as resin for polyurethane foam, resin for polyisocyanurate foam, resin for phenol foam, and flame retardants and flame retardant aids (borax, sodium metaborate). , calcium carbonate, aluminum hydroxide, antimony dioxide)
, bentonite, pearlite grains, and shirasu balloons. Reference numeral 18 covers the exposed surface of the heat insulating material 16 with a backing material to make the board a sandwich structure, improving the mechanical strength of the board itself, as well as a noncombustible sheet, a waterproof membrane, a heat shield sheet, a water absorbing sheet, a soundproof sheet, It serves as a backing material, such as asbestos paper, kraft paper, asphalt felt, metal foil (AI!, Pb).

[Construction example]

Next, construction examples will be explained. Assume now that boards as shown in FIG. 1 are laid horizontally as shown in FIG. 6 to form an exterior wall. Therefore, studs, wall base, or rim A
Then, fix the fixing part 13 of the first stage board (3) with the nail B. Next, the locking portion ↓ of the second-stage board @ is engaged with the engaging portion of the first-stage board ■, and its fixing portion 13 is fixed to the furring A in the same manner as above. Therefore, in order to construct the entire outer wall, the above steps can be performed sequentially from the base side toward the girder.

[Other Examples]

What has been described above is only one embodiment of the board according to the present invention, and FIGS. 7(a) to (C), FIGS. 8(a) and (b), and FIGS. Figures 10(a) to (f), Figures 11(a) to (e), and Figures 12(al to (e)
) can also be formed as shown in FIG.

In other words, Fig. 7(c) shows a board in which two decorative grooves 3 are formed on the decorative surface 2, and the depth d is different from the above, and Fig. 8(a) shows a board with two decorative grooves 3 formed on the decorative surface 2. 9(a) to (g) show modified examples of the locking portion ↓, and FIG. 10(a) ) to (f) are modified examples of the protrusion 11,
FIGS. 11(a) to 11(e) show cutout portions 17 of the heat insulating material 16.
This is a modification of the shape. FIGS. 12(a) to 12(e) show modified examples of the board, and FIG. 12(a) shows a board in which one side edge of the back material 18 on the main side of the engaging portion protrudes by ΔE.
Figure e1 shows a board in which grooves 19 are provided on the back surface of the heat insulating material 16 in parallel to the longitudinal direction.

〔Effect of the invention〕

As described above, according to the board according to the present invention, capillarity does not occur in the continuous structure of the locking part and the engaging part, and the tongue of the locking part and the protrusion of the engaging part prevent rainwater from flowing. Since there is no leakage to the inside of the board, it has the characteristic that it will not corrode the foundation or the inside of the wall. Additionally, the board is fixed in a location where rainwater does not infiltrate, which has the advantage of preventing rust from forming on the fixed part. Furthermore, since the decorative grooves are formed on the decorative surface, the long board will not warp, twist, or deteriorate its appearance due to cracks, etc. Moreover,
The decorative groove has a scalene trapezoidal longitudinal cross section, which is the same as the appearance of the joints when the boards are connected, so the joints function as a pattern just like a conventional wall, and can be configured to create a beautiful wall appearance. . In addition, the decorative grooves and joints have trapezoidal vertical cross sections, which allow for better drainage and create a three-dimensional effect rather than the actual dimensions. Furthermore, because we created a process difference of Δh between the joint basement part and the fixing part, and matched the height relationship between the locking part and the engaging part, there was no need to make large cutouts in the insulation material. It has the effect of improving sex. In addition, because the heat insulating material is placed on the back of the engaging and fixed parts, vibrations from the base are not directly transmitted, the connecting parts do not separate, and the surface material prevents it from forming a thermal bridge. . In addition, because the recess is integrally filled with insulation material and the back side is covered with a sheet-like material, when a wall is formed with a board with a sandwich structure, it has sound insulation, heat insulation, vibration insulation, and fire resistance. , dew condensation resistance, and mechanical strength are significantly improved.
