Description

[Detailed Description of the Invention] The present invention relates to a siding board useful as an exterior material for buildings and structures.

In particular, the present invention relates to a sighting board with improved airtightness, backing properties, cushioning properties, and waterproof properties in the connecting portions.

In general, although sighting boards have excellent construction properties, they also have problems with insulation, waterproofing, windproofing, and backing properties at the connecting parts, as well as leakage of rainwater from the nail attachment site to the rim, and the resulting rust of the nails. There were disadvantages such as corrosion of the fuselage rim and the resulting separation due to strong winds.

For example, there is a sighting board that has improved this drawback, as disclosed in Japanese Utility Model Publication No. 53-52113.

However, in the case of this insulation board, the thickness is about 0.1 m.
Since the waterproof sheet of approximately 300 m in length was only protruded outward from the edge of the female connecting part, and it was a film-like smooth sheet, there was a disadvantage that the fitting part lacked waterproofness and backing properties.

Furthermore, if the waterproof sheet only protrudes from the edges of the connecting portions of the siding boards, there is a drawback that water that has entered through the connecting portions due to capillary action or the like will directly diffuse and corrode the base material and the heat insulating material.

In addition, since the fixed part of the sighting board, the so-called nail attachment part, is simply bored as a blank hole, it is not possible to prevent water from entering from this part, and there are disadvantages such as corrosion of this part containing the nails. Ta.

In order to eliminate these drawbacks, the present invention uses a concave-convex structure on the protruding part of the tarpaulin sheet and the part that contacts the lower edge of the female connecting part to provide cushioning, backing, waterproofing, and heat insulation properties. To provide a siding board with improved defects.

An embodiment of the siding board according to the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a perspective view showing the siding board,
1 is mainly formed by bending a plate such as a metal plate or a synthetic resin plate.

That is, the main body 1 has a square or rectangular decorative surface 2,
Side walls 3, 4 with both end edges extending downward; and side walls 3, 4.
The male and female connecting portions 5 and 6 are integrally molded, the ends of which extend in a direction parallel to the decorative surface 2, and which are fitted into and connected to each other.

To explain in more detail, the male connecting part 5 consists of an insertion edge 7,
The female connecting part 6 has a U-shaped insertion groove 8, an extension part 9, and a tongue piece 10.
It consists of

Reference numeral 11 fills a recess surrounded by the back surface of the decorative surface 2 and the back surfaces of the side walls 3 and 4 with a heat insulating material.

As the heat insulating material 11, synthetic resin foam, glass wool,
It is a lamination or mixture of one or two types of rock wool, cellulose, sheathing board, etc.

In addition, the heat insulating material 11 is not limited to the above-mentioned heat insulating material alone;
It also includes materials that are flame retardant, waterproof, chemical resistant, soundproof, modified, etc.

Preferably, synthetic resin foams that are non-water absorbing, hygroscopic, and have excellent chemical resistance, as well as moldability, super insulation properties, corrosion resistance, and cushioning properties, such as polyurethane foam, urethane, phenol-modified polyisocyanurate foam, and phenol foam. , vinyl chloride foam, polyethylene foam, polyolefin foam, polystyrene foam, polyamide foam, etc., and is integrally filled into the recessed portion by molding or in-situ foaming.

In addition, when using a molded body, an adhesive is used.

Reference numeral 12 covers the back surface of the insertion edge 7, the extension portion 9, and the heat insulating material 11 with a waterproof sheet, and has a protruding portion 13 that protrudes outward from the end of the female connecting portion.

The protrusion 13 has at least one function of backing properties, cushioning properties, and heat insulation properties.

This is to provide waterproofness, airtightness, heat insulation, vibration resistance, and corrosion resistance to the connecting portion of the sighting board.

Its specific structure is an uneven structure (wavy, pipe-like, bubble-like) and has flexibility.

In addition, the height difference of the uneven shape is about 1 to 5 mm, and the length △l = 5
It is approximately 20 mm, and is determined mainly by the relative relationship with the gap between the connecting parts.

This is to avoid failure of the desired function as described above in the case of a film or sheet having low unevenness, for example, in the form of a film or sheet.

The waterproof sheet 12 is made of one or more laminated sheets of kraft paper, asbestos paper, synthetic resin sheet, metal foil, tarpaulin paper, asphalt felt, and foam sheet (asbestos, synthetic resin).

In addition, in the above-mentioned sheet, it is desirable that the material lacking waterproofness be provided with waterproofness and water repellency.

This is to prevent capillary action. Next, construction examples will be explained in detail.

For example, a base material of a colored iron plate (plate thickness: 0.27 mm) is shaped to produce the main body 1 having the shape shown in FIG.

In addition, a polyurethane foam raw material is injected as a heat insulating material 11, and is reacted and foamed, and is brought into contact with the back side of a waterproof sheet 12 (polyethylene film laminated on the surface of kraft paper), and gradually adhered and hardened.

Note that the length of the protruding portion 13 is Δ1-10 mm, and the height of the waveform Δt is 3 mm.

Therefore, it is assumed that an outer wall as shown in FIG. 2 is to be formed.

First, the extension part 9 of the siding bobbed B1 is fixed onto the furring A with nails C.

Next, insert the insertion edge 7 of the siding board B2 into the insertion groove 8 of the siding board board, and insert the extension part 9 of the other end into the nail C.
Fix it in the same way as above.

That is, the outer wall can be easily formed by sequentially repeating this operation.

Therefore, when observing the connection part of this outer wall, we found that the uneven structure (
The so-called protrusion 13) was surely interposed.

Further, the nail C was fixed in a state where the protrusion 13 provided airtightness and waterproofness.

Furthermore, the tip of the protrusion 13 is connected to the siding board B2.
The back portion of the heat insulating material 11 is brought into contact with the back surface of the heat insulating material 11 through the waterproof sheet 12 while exhibiting cushioning properties, and functions as a heat insulating layer and a final waterproof layer.

What has been described above is only one embodiment of the present invention, and it can also be formed as shown in FIG. 3 or FIG. 4.

That is, FIG. 3 shows a case in which the waterproof sheet 12 has an uneven structure on its entire surface, and FIG. 4 shows a case in which the protrusion 13 is folded back onto the surface of the extension part 9 to form a siding board.

Also, Fig. 5a. It is also possible to form the protrusion 13 with an uneven structure as shown in FIG.

As described above, the siding board according to the present invention has the feature that the waterproofness, heat insulation, vibration resistance, and corrosion resistance of the connecting portion can be significantly improved.

In addition, nails and the like are securely fixed and there is no corrosion, so there is no deterioration of the insulation material and no separation of the siding board.

Another feature is that the nail-fixed portion of the sighting board is provided with cushioning properties to ensure secure fixation with nails.
