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, when the boards shown in Figure 2 (al) are laid horizontally to form an exterior wall, the vertical joint α is as shown in Figure 2 (
As shown in b), the back amplifier material G is pushed onto the studs or the rim F, and the 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 0.35 tm), and the other portions are bonded to the end surface of the core material D, for example, a plastic foam. However, since plastic foam is brittle and has a foam structure that is difficult to adhere to, adhesion between plastic foam and caulking material H is difficult.
It did not contribute to adhesion at all. As a result, the caulking material H only slightly adhered to the end surface of the metal plate A.
Easily damaged by external force or weather-resistant deterioration,
The filling work requires skill, and since the outer wall surface and the exposed joint surface need to be flush, the appearance must be beautiful, and the construction process takes a long time.

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 type of board is produced on a continuous line and cut with a running cutter, the end of the board is deformed on the end face side of the long decorative surface, resulting in a state where the vicinity of the end is compressed and deformed (front wobbling). There was a disadvantage.

[Object 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 provided with a rib-like shape. Alternatively, a tongue piece bent in an arc shape 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.
Moreover, we are proposing a board that is more beautiful in a short time and has sufficient adhesive strength to prevent 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 plated steel sheets (product names: Galfan, Galvalume Steel Sheet, Super Zinc Steel Sheet). ), 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, 30 to 150 degrees inward.
The side wall 4.5 bent at the
It is formed into a box shape with an end wall 6 bent at an angle of about 150°. In particular, as shown in FIGS. 3(a) and 3(bl), the end wall 6 has its tip shaped like a seam ((a) figure) or an arc shape ((b) figure) inwardly or outwardly. (not shown) is provided with a bent tongue piece 7. This end wall 6 includes a reinforcing piece to prevent warping and twisting of the decorative surface and front wobbling on the butt end surface, an adhesion surface of caulking material, In addition to functioning as a raised piece, it is useful for protecting the core material 17 by blocking rainwater, heat, and sunlight from entering from the end surface of the board. Same as the height of side wall 5, half of side wall 4, or core material 1
It can be set to any height, such as the same height as 7. 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. Incidentally, when the height h of the end wall 6 is made the same as that of the side wall 4, the female connecting portion is cut out so as not to interfere with the connection of the boards. The male connecting part consists of an insertion edge 9 projecting outward from the lower end of the side wall 4, and a flap-shaped tongue piece 10 provided at the tip of the insertion edge 9 as required.

In addition, the female connecting part (■) bends the lower end of the side wall 5 inward, and bends outward again, forming an insertion groove 12 with a U-shaped cross section and a lower edge 13 of the insertion groove 12 outward. an extended extension part 14;
A protrusion 15 provided as necessary in the middle of the extension part 14, and a flap-like tongue piece 16 provided as necessary at the tip of the extension part 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 bank-up material. Specific materials include polyisocyanurate foam, polyurethane foam, phenol foam, polyethylene foam, polyurea foam,
Or, foams that are mixed with one or more of borates, silicates, pearlite grains, and fibers, and have enhanced flame retardancy and mechanical strength, or foamed plaster, foamed concrete, foamed glass, rock wool boards, etc. wood wool cement board,
One or two types of non-combustible board materials mainly composed of gypsum slag or steelmaking slag, asbestos-cement systems, ALC systems, or compositions in which a resin component that functions as an adhesive is added to these materials.
It consists of a layer of seeds or more. 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. Also, back material 1
8 covers the back side of the core material 17 and is glued to the back side of the insertion edge 9 if necessary.It mainly strengthens the mechanical strength of the board itself, and also covers the back side of the core material 17, as well as the noncombustible sheet, waterproof membrane, and heat shielding material. It functions as a member of sheets, humidity control sheets, soundproof sheets, release sheets, backing materials, reinforcing sheets, etc. Examples of materials include asphalt felt, synthetic resin sheets, asbestos paper, metal foils (Al,
Pb, Fe, Cu), a laminate of one or more types of kraft paper, or a paper that has been treated to be waterproof, flame retardant, etc.

In addition, in order to form a wall by constructing the above-mentioned boards horizontally, as shown in Figure 4, the boards should be connected to the vertical rim and studs 19 shown by the two-dot chain line toward the girder base. and form a vertical joint β. Next, 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+n) was used as the surface material, the width was 380n, the length was 3,030mm, the height of the end wall 6 was 7mm, and the core material 17 was made of polyester on the back of the main body 2. Isocyanurate foam is discharged as a raw material, reacted and foamed to a density of 30 kg/n? A board as shown in FIG. 1 was manufactured by preparing aluminum kraft paper as the backing material 18. On the other hand, as a comparative example, a board without the end wall 6 as shown in FIG. 4 was used, and the board was molded using the same width, length, and material. For both boards,
The following various tests were conducted. Namely, ■ Moist heat, drying test, ◎ Density variation test of core material 17, ○ Bending test of irregularities in the width direction of decorative surface 3, ■ Torsion test in the length direction, ■ Waterproof test of joint parts, O When filling with caulking material. Workability, ■ Appearance observation after manufacturing, ■ Defective product rate (
(viewed from the appearance of the wood end) and (2) measurement of deformation during cutting. The results were as shown in the table below. In addition,
■Dries at 80±5°C for 105 minutes, 90% R11 and 2
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 weight is 30-33kg/n? , the latter is the appearance of the decorative surface when the foam structure has many voids at 20 to 40 kg/d, and O is when the tongue piece 10.16 is held with both hands and a moment is applied so that it forms a mountain and valley shape. , ■ is the shape when twisted at both ends of the 1,000 fin length and the appearance when external force is removed, ■ is the back side when water is jetted against the joint with a pressure of 70 kgf. ■ is the filling time for the same length and width, ■ is the overall observation of the board, and ■ is the percentage of boards that are defective due to the end surface.

In addition, ■ and ■ indicate that when the height of the decorative surface increases or decreases by 111, the back material 18 shrinks or expands in the width direction by 1.2 m.
60 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.
