Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a siding board (hereinafter simply referred to as a board) used for forming horizontal walls of buildings and structures.

[Conventional technology]

This type of board that has been used in the past is ■Special Publication No. 51-29339, ■Jet Publication No. 51-11882, ■
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 is used, the connecting parts of the boards are often in direct contact with the underlying material, so condensation often corrodes the underlying material, and it is also difficult to prevent damage caused by earthquakes. Since the vibrations and deformations of the 11 bodies were directly transmitted, there was a disadvantage that it was easy to separate the tax.

[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 into the concave area surrounded by the board, and the insulating material is also placed on the back side of the engaging part, so that the decorative surface is free of cracks, deformation, warping, and twisting, and also prevents the board from curling up. In addition, a notch is provided near the locking part of the heat insulating material, and the upper part of this notch has the same shape as the end of the engaging part, so that it will engage with the upper notch when the board is installed. The edges of the sections are combined to make the back side of the board flush, providing workability, corrosion resistance, fire protection, cushioning, productivity, and vibration isolation, and creating beautiful joints with a rich three-dimensional effect. We propose a board that can be used to construct a wall.

[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,
It is formed from an engaging part 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 backward 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 ball is located between the decorative surface 2 and θ3-90°, the so-called horizontal base 5, the locking piece 6 that is almost perpendicular to the top, and the tip of the locking piece 6. and a tongue piece 7 bent outward or inward (not shown) in a seam-like manner. The bottom side 5 promotes the three-dimensional appearance of the joint by shading at right angles, and the locking piece 6 has a large area in contact with the engaging part work described later, and also serves as a guide during construction.
and a stabilizing support piece, which acts as a waterproof surface. In addition, the tongue piece 7 is used to form a gap to prevent capillary phenomenon from occurring at the anchorage portion with the protrusion 11 (to be described later), and to prevent the tip of the locking piece 6 from becoming sharp like a knife during construction. This helps eliminate danger during work. The main engaging part is shown in Figure 5 (a
), as shown in (b), the upper end of the decorative surface 2 is connected to the inclined portion 9 which is curved backward at an angle θ′2 corresponding to the angle θ2 of the inclined surface 3a of the decorative groove 3, and the edge thereof is directed upward. The joint base part 10 extends perpendicularly to the joint base part 10, the rib-shaped protrusion 11 slopes at an angle θ4 (acute angle) with respect to the surface of the joint base part 10, and the protrusion 1
For further explanation, the outer tip of 1 can be bent horizontally (Fig. This prevents rainwater from accumulating in the portion IO, promotes a three-dimensional effect when forming the joint, and is useful for increasing the working width.

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. In addition, the protrusion 11 engages the locking piece 6 under a certain elasticity, and also has a rain cover and reinforcement to prevent deformation on the surface material and the shape of the triangular bent portion 11a. This prevents capillary action between the strips 11. 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 height h 1 of the base 5 and the width W on the surface material.

Reference numeral 13 denotes a fixed part, which is formed by vertically bending the tip of the upper end wall 12 upwards, and mainly fixes the surface material 1 in a position where rainwater does not leak, as shown in FIG. base plate)
This is useful for fixing to α via the nail β. 14
The tip of the fixed part 13 is formed with a tongue piece as necessary, and is mainly used to prevent danger during construction and to prevent deformation of the fixed part 13 such as waving. Reference numeral 16 denotes a heat insulating material, which is disposed on the back side of the gutter-shaped part 15, the engaging part work, and the fixing part 13, and mainly provides heat insulating properties to the board A, and secondarily includes core material, cushioning material, It functions as a reinforcing material, an adhesive, a soundproofing material, a moisture-proofing material, and a rust-preventing material. Its shape corresponds to the gutter-like portion 15, and a cutout portion 17 is provided near the locking portion. To explain further, insulation material 1
6 is arranged on the back side of the fixing part 13, so it alleviates the vibration of the base, prevents the connection part from coming off due to earthquakes, etc., and also prevents the top of the surface material from forming a thermal bridge, thereby improving the insulation properties. This provides Board A with improved functionality. 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., which is discharged as a raw material, molded, hardened, self-adhesive, or It is made of one type such as a molded body. 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, methane). 1 fii or more of sodium borate, calcium carbonate, aluminum hydroxide, antimony trioxide), bentonite, pearlite grains, and shirasu balloons. For convenience, the notch 17 is divided into a lower notch 17a and an upper notch 17b, and the lower notch 17a is used as a space for connecting the engaging part work and the locking part work of the board A. The upper notch 17b is for ensuring that the back surface is flush with the board A as shown in FIG. 6 when the board A is installed. The shape is suitable for the. Therefore, the wall base is in a sealed state with the heat insulating material 16, so that the heat insulation properties are improved. Furthermore, if a fire-retardant heat insulating material is used, the wall is completely covered with the heat-insulating material, making it highly fire-retardant.

Moreover, when the notch 17, especially the upper notch 17b, engages the board A, it combines with the end of the lower board A on the main side of the engaging part, as shown in FIG. In order to prevent board A2 from falling downward,
This makes the work easier and also serves to prevent the connection part from coming off. Reference numeral 18 covers the exposed surface of the heat insulating material 16 with a backing material to make the board A a sandwich structure, thereby improving the mechanical strength of the board A itself. It serves as a backing material, etc.

The materials include, for example, asbestos paper, kraft paper, asphalt felt, metal foil (A I-, Pb5Fes C
u), tfi such as a synthetic resin sheet, rubber sheet, cloth sheet, glass cloth, or a combination of one or more of these, or a sheet treated with waterproofing or flame retardant treatment. Here, to briefly explain the sizes of the above-mentioned parts, in the decorative groove 3 (Fig. 3), the length 11 of the bottom surface 3a, the width W of the opening and the height d, and the locking part ↓ (Fig. 4).

In other words, the above relationship means that when boards A are connected, the appearance of the decorative ?a3 and the joints of the connecting parts will be very similar, creating a unified line in the wall, and improving the design. This is to form a wall body rich in heat, and also to make the back surface of the board flush with the board, thereby improving the heat insulation and fire prevention properties of the board A.

[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. In the board A r sA2, the top surface material is a colored steel plate with a thickness of 0.27 m, the back surface material 18 is aluminum kraft paper, and the heat insulating material 16 is polyisocyanurate foam. Therefore, the n-th board A1 is fixed to the wall base α consisting of main pillars, studs, rims, waterproof sheets, etc. (the figure shows the wall base when no waterproof sheets are used) via nails β. Next, engage the locking part of board A2 on the n+1st stage with the engaging part of board A on the first stage,
The fixing portion 13 is fixed to the wall base α in the same manner as described 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. It can also be formed as shown in FIGS. 10 (al to 5) and 11 (a) to 11 (f). In other words, in FIGS. 8(a) and 8(b) show a decorative groove 3 having a trapezoidal trapezoid shape with a slightly modified longitudinal cross-sectional shape of the decorative groove 3. Figure 9 (al~(
g) shows a modified example of the locking area, and Fig. 10 (al to (f)
1 is a modification of the protrusion 11. Also, Fig. 11(a)-(
f) is another embodiment of board A, (Fig.
Figures 1) to (e) are board A in which one or more grooves 19 are provided on the back side of board A in parallel to the longitudinal direction of board A; This board A has a rectangular shape and has no distinction between a lower notch 17b and an upper notch 17b.

〔Effect of the invention〕

As described above, according to the board according to the present invention, capillarity does not occur in the connection structure between 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 it does not penetrate inside the board, it has the characteristic that it will not corrode the base or the inside of the wall. Additionally, since the board is fixed in a location where rainwater will not infiltrate, there is an advantage that the fixing equipment will not rust. 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 similar to the appearance of the joints when the boards are connected, so the joints function as a pattern and can be constructed into a wall with a beautiful 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, a height difference of Δh is provided between the joint basement part and the fixed part,
In addition, since the height relationship between the locking part and the engaging part is made to correspond, there is no need to make a large cutout part of the heat insulating material, which has the effect of improving heat insulation properties. In addition, because the heat insulating material is placed on the back side of the engaging part and fixed part, the vibration of the base is not directly transmitted, and in order to prevent the surface material from becoming a thermal bridge, it is necessary to This has the effect of preventing spills caused by bridges. Also, when the board is installed, the back side of the board will be flush, and
Since the wall base is completely coated with insulation material, insulation and fire protection properties are improved. Moreover, when the boards are engaged, the notches and the ends of the boards are combined, and the boards do not slide downward, making the work easier and preventing the connecting parts from coming off. Moreover, since the gutter-like part is integrally filled with heat insulating material and the back side is covered with a sheet-like material, when the wall is formed, it has sound insulation, heat insulation, vibration proof, fire resistance, dew condensation resistance, and has the effect of significantly improving mechanical strength.
