Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides siding useful for constructing the outer walls of buildings and structures in a horizontal or vertical manner, with the joints sealed with caulking material. This relates to a board (hereinafter simply referred to as a board).

[Conventional technology]

Conventionally, this type of board has been made by forming a metal plate A into a gutter shape, and extending the left and right side wall edges outward to form a male connecting part B and a female connecting part C, as shown in Fig. 2(a). Usually, the gutter-like portion is filled with a core material, and the back surface is covered with a sheet-like material E if necessary. However, although boards of this type of structure are suitable for constructing external walls with vertical panels, there are various drawbacks when they are used as vertical panels. In other words, the seam area α when the boards shown in Figure 2 (al) are laid horizontally to form the outer wall is as shown in Figure 2 (
As shown in bl, the structure is such that a high back-up material G is pushed onto the studs or the rim F, and a caulking material H is filled on top of it. In other words, the caulking material H is bonded only to the end surface of the metal plate A (thickness: 0.27 to 0.3511), and the other portions are bonded to the end surface of the core material D, for example, a plastic foam. however,
The plastic foam and caulking material H did not contribute to adhesion at all because the plastic foam was brittle and had a foam structure that was difficult to adhere to. As a result, the caulking material H only slightly adheres to the end surface of the metal plate A, and is easily damaged due to external force or weather-resistant deterioration, and requires skill in filling work. Since the outer wall surface and the exposed joint surface need to be flush with each other, it is necessary to create a beautiful appearance, which has the disadvantage of requiring a long time for construction. In addition, conventionally used boards are extremely susceptible to bending in the width direction of the decorative surface and deformation of the core material, and have the disadvantage that the decorative surface may warp or twist in an uneven manner.

Furthermore, since this ring board is produced on a continuous line and cut with a running power lid, the end of the ring board is deformed on the end surface side of the long decorative surface, so-called a depressed state (front wobbling) where the vicinity of the end is compressed and deformed. There was a disadvantage that this occurred.

[Purpose of the invention]

In order to eliminate such drawbacks, the present invention forms an end wall by bending at least one of the short ends of the decorative surface inward, and the tip of the end wall is bent in a flap or an arc shape. A tongue piece is provided to prevent deformation of the decorative surface, and
It prevents waving on end walls and makes it extremely easy to apply caulk to vertical joints when boards are butted longitudinally.
In addition, we are proposing a board that is more beautiful in a short time, has sufficient adhesive strength, and prevents the caulking material from being damaged.

[Structure of the invention]

The board according to the present invention will be explained in detail below using the drawings. FIG. 1 is a perspective view showing typical examples of the above-mentioned boards, such as surface-treated steel sheets, steel sheets plated with zinc-nickel alloy, aluminum-zinc alloy Mebuki steel sheets (product names: Galfan, Galvalume steel sheet, Super Zinc). ), metal plates made of one type of aluminum plate, aluminum alloy plate, copper plate, etc. (including flat plates and embossed plates)
Surface material and back surface material 18 formed by molding with a roll or press, or by one type of extrusion molding.
A core material 17 is integrally filled in between.

To explain further, the surface material is composed of a main body 2, a male type connecting part body, and a female type connecting part body.

That is, the main body 2 has a rectangular decorative surface 3 and both edges thereof in the longitudinal direction at an arbitrary angle, for example, perpendicularly, or inwardly by 30°.
The side wall 4.5 is bent at an angle of 150＠, and the decorative surface 3
It is formed into a box shape with an end wall 6 in which at least one of the side edges in the short direction is bent inward, for example, at about 30 to 150 degrees. In particular, the end wall 6 is shown in FIG.
As shown in b), a tongue piece 7 is provided, the tip of which is bent inwardly or outwardly (not shown) in the shape of a seam (Figure (a)) or in the shape of an arc (Figure (b)). It is something. This end wall 6 functions as a reinforcing piece to prevent warpage, twisting, and front wobbling of the decorative surface, an adhesion surface for caulking material, and a raising piece, and also prevents rainwater, heat, and sunlight from entering from the end face of the board. This serves to block and protect the core material 17. Further, the height h of the end wall 6 is set to an arbitrary height such as the same height as the side wall 4, the same height as the side wall 5, half the side wall 4, or the same height as the core material 17. To explain further, the end wall 6 prevents deformation of the end of the board, so when the wall is formed vertically, the exposed edge of the board becomes straight, improving aesthetics. . Furthermore, when used as a horizontal covering, the waterproofness at the butt portions of the boards is improved, as shown in FIG.

In addition, the tongue piece 7 is used to prevent the end wall 6 from waving and to make it easier to butt the boards together.
This prevents the tip of the end wall 6 from becoming like a sharp knife during work, and is useful for eliminating danger during work. Note that when the height h of the end wall 6 is made the same as that of the side wall 4 or the same as that of the core material 17, the height h of the end wall 6 is made the same as that of the side wall 4 or the core material 17, so that the male and female connection parts, It is a cutout. The main male connecting portion consists of an insertion edge 9 projecting outward from the lower end of the side wall 4, and a flap tongue 10 provided at the tip of the insertion edge 9 as required. In addition, the female connecting portion 12 has an insertion groove 12 whose lower end of the side wall 5 is bent inward and bent outward again to have a U-shaped cross section, and a lower edge 1 of the insertion groove 12.
3 to the outside, a protrusion 15 provided as necessary in the middle of the extended portion 14, and a flap-shaped tongue piece 16 provided as necessary at the tip of the extended portion 14. It is composed of Furthermore, the core material 17 is a material that is discharged as a raw material into the main body 2, which also serves as a mold material, and is bonded and cured to integrally fix the surface material and the back surface material 18, or a molded product, and is mainly used as a heat insulating material, a fireproof material, etc. It functions as a material, cushioning material, soundproofing material, vibrationproofing material, adhesive, and back-up material. As shown in sections for convenience, the cross section consists of an upper part 17a filled in the concave part of the main body 2, a male and female connecting part, and a bulging part 17b bulging downward from . It has a shape cut out from the tip of the insertion edge 9 to Wl. That is, Wl is Wl - Wl, where Wl is the distance from the innermost part of the insertion groove 12 to the side edge of the female connecting part (2) of the bulging part 17b.
, or w, 4w2, and when the board is installed, the back surface becomes flush, covering the base surface and improving heat insulation and fire resistance. In addition, the material of the core material 17 is polyisocyanurate foam, polyurethane foam, phenol foam, polyethylene foam, polyurea foam, or a mixture of these with one or more of borates, silicates, pearlite grains, and fibers, so-called. Foam with enhanced flame retardancy and mechanical strength, foamed gypsum, foamed concrete, foamed glass, rock wool board, wood cement board, noncombustible board materials whose main components are gypsum slag and steel slag, asbestos cement type, ALC type , or a composition in which a resin component that functions as an adhesive is added, or a laminated product of one or more of these. In addition, when a molded body is used for the core material 17, it is necessary to use an adhesive between the back material 18 and the core material 17 on the surface material, although not shown. In addition, the back material 18 covers the back surface of the core material 17 and is glued to the back surface of the insertion edge 9 if necessary.It mainly strengthens the mechanical strength of the board itself, and also serves as a noncombustible sheet, a waterproof membrane, etc. , a heat shielding sheet, a humidity control sheet, a soundproofing sheet, a release sheet, a backing material, a reinforcing sheet, etc. Examples of the material include asphalt felt, synthetic resin sheet, asbestos paper, metal foil (l5PbSFeSCu), kraft paper, a laminate of one or more of them, or a material treated with waterproofing, flame retardant, etc. etc.

In addition, in order to form a wall by constructing the above-mentioned boards horizontally, as shown in Fig. 4, the boards should be connected to the vertical rim and studs 19 shown by two-dot chain lines from the girder toward the foundation. However, after forming the vertical joint β, the raising material 20 is inserted into the vertical joint β, and then the caulking material 21 is filled so as not to protrude from the decorative surface 3. The vertical joint β formed in this way is similar to the vertical joint α of the conventional horizontal board.
(As shown in Fig. 2(b)), since the adhesion area between the surface material and the caulking material 21 is large, waterproofness, workability,
It has excellent vibration resistance.

〔Example〕

A colored steel plate (plate thickness 0.27 m) was used as the surface material, the width was 380 m, the length was 3,030 mm, and the end wall was 6.
The height of the core material 17 is 7 cranes, and the core material 17 is made by discharging polyisocyanurate foam as a raw material onto the back surface of the main body 2, reacting and foaming it to form a density of 30 kg/cd, and the back material 18 is aluminum kraft paper. A board as shown in FIG. 1 was manufactured by preparing the following. On the other hand, as a comparative example, as shown in FIG. 2, a board without the end wall 6 was used, and the width, length,
They were molded using the same material. The following various tests were conducted on both boards. Namely, ■ Moist heat, drying test, @ density variation test of core material 17, bending test of irregularities in the width direction of O decorative surface 3, ■ twist test in the length direction, ■ waterproof test of joint parts, ■ when filling with caulking material. We measured workability, (1) observation of appearance after manufacturing, (2) measurement of defective product rate (viewed from the appearance of the butt end), and (2) measurement of deformation during cutting. The results were as shown in the table below. In addition, ■ is dried at 80±5℃ for 105 minutes and dried at 90%RH for 2 hours.
The height of the convex shape from the horizontal plane at the center of the decorative surface after standing for a period of time is +, and the concave shape is -. The former is 30-33 kg/m, the latter is 20-40 kg/m, and the appearance of the cosmetic surface when the foam structure has many voids. , Appearance when a moment is applied to form a valley shape, ■ is the shape when twisted at both ends of a length of 1,000 m, and appearance when external force is removed, ■ is for the joint part, Water leakage to the back side and damage to the joint when water is ejected at a pressure of 70 kgf, O is the filling time for the same length and width, ■ is the overall observation of the board, ■ is a board that is defective due to the end surface The ratio , ■ is the deformation due to front sagging caused by cutting.

Below, the margins \, \, Note that ■ and ■ indicate that if the height of the decorative surface increases or decreases by one crane, the shrinkage or elongation of the back material 18 in the width direction will be 12D. (2) is because the foamed structure of the core material 17 is exposed at the end of the wood, resulting in poor filling and non-uniformity of the foamed structure.
