Description

[Detailed Description of the Invention] The present invention relates to a siding board used for exterior wall materials, roofing materials, and interior materials of buildings and structures.

For example, as exterior walls, cement, mortar walls, and panel walls are common, and because of the construction period, bottom-shaped board materials, such as metal siding materials, are increasingly used.

Additionally, walls for insulation structures are attracting attention from the standpoint of energy conservation.

Examples include Utility Model Publication No. 49-42022 and Utility Model Application Publication No. 52-138623.

However, in boards with this male-female structure, the airtightness of the joints always became a major problem.

In other words, no matter how high the insulation properties of the insulation material are, the insulation, waterproofing, soundproofing, etc. functions of the entire mold are greatly reduced because the connecting parts have loose structures or the surface materials are simply in contact with each other. It was something that

In order to improve these, for example, from a waterproof perspective,
There are also composite panels such as Utility Model Publication No. 50-89, Utility Model Application No. 52-151611, or a structure in which a backing material is separately interposed in this portion.

However, the main function of these materials was waterproofness, with the secondary effect of providing insulation through airtightness (sealed structure).

Of course, even in this case, the connecting portion is a contact between rigid metal plates, which has the disadvantage of lacking airtightness.

In addition, when a board is constructed by forming a step in the height of the side walls of the male and female joints, the decorative surface on the insertion edge side will be higher than the other decorative surfaces, which has the disadvantage of creating a step on the decorative surface. Ta.

In view of these shortcomings, this invention was developed as a result of intensive research.
Together with those forming the connection part that has heat insulation, waterproofness, soundproofing, and impermeability (sealed structure) in this connection part,
We propose a siding board that has excellent insulation throughout the wall, has a beautiful appearance, and has excellent engagement force.

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 a specific example of the siding board according to the present invention, in which 1 is a surface material, 15 is a synthetic resin foam,
Reference numeral 16 is a back material, and a synthetic resin foam 15 having appropriate elasticity, rigidity, and heat insulation properties is bonded between the surface material 1, which is elastic and easy to mold, and the back material 16, which is waterproof, strong, and smooth. This siding board has significantly improved mechanical strength due to its sandwich structure.

To explain further, the surface material 1 is made of one type such as galvanized iron plate, colored steel plate, aluminum plate, etc., which has a thickness of 0.27 to 1 mm and has rigidity and elasticity even after forming. It was molded as shown in Figure 1.

That is, the surface material 1 consists of a long decorative surface 2 and side walls 3 and 4 whose longitudinal edges are bent inward, and a main body 5 having a concave cross section and the lower ends of the side walls 3 outward. The lower end of the male connecting portion 8 and the other side wall 4 is bent inward, and is formed from an insertion edge 6 whose tip is bent and whose tip is extended outward, and a tongue piece 7 whose tip is bent outward, The shape is formed by an extension part 11 which is bent outward again and extends the insertion groove 9 and its lower edge 10 outward, a protrusion 12 formed in the middle thereof, and a tongue piece 13 whose tip is bent outward. It is composed of a female type connecting part 14.

The tongue piece 7 has a shape such as an inverted letter shape, a hook shape, a semicircular shape, a spiral shape, etc., and has a sharp knife-like end surface that is in direct contact with the back surface of the synthetic resin foam, which will be described later. The outer periphery of the tip should be curved or slightly flat in order to prevent it from forming, to maintain airtightness through cushioning properties (using the difference in elasticity between the main body and the synthetic resin foam), and to prevent danger during construction. Form into a curved surface.

In addition, the synthetic resin foam 15 bulges downward from the recess of the main body 1, the lower edge of the insertion edge 6, and the lower edge of the extension portion 11, and accommodates the female connecting portion 14 inward from the side wall 3. The cutout portion 17 is shaped like this.

An example of the synthetic resin foam 15 is one made of one of polyurethane foam, polyisocyanurate foam, phenol foam, and urea foam, and the foam itself has excellent waterproof, moisture-proof, weather-resistant, and corrosion-resistant properties. In addition, the contact portion has a certain degree of elasticity.

In addition, the backing material 16 is flexible, such as kraft paper,
It consists of asbestos paper, aluminum foil, raw foil, asphalt roofing, synthetic resin film, and the above-mentioned sheet-like materials subjected to waterproof treatment or laminated with two or more of them.

Here, to briefly explain the dimensions of the siding board according to the present invention, the thickness from the surface of the decorative surface 2 to the surface of the back material 16 is T3, the height of the side walls 3 and 4 is, h
2. The depth of the notch 17 is Dl, and the height of the tongue piece 7 is h3.
, the height of the tongue piece 13 is 1, the height of the protrusion 12 is N1, the height of the opening of the insertion groove 9 is 1, the thickness from the extension part 11 to the back material 16 is T2, and from the tip of the insertion edge 6 The length to the inner edge of the notch 17 is L2, the length from the deepest part of the insertion groove 9 to the end of the tongue piece 13 is L2, the length of the insertion edge 6 is L3, and the length from the tip of the insertion groove 9 is L2. Assuming that the length to the side edge of the back material 16 is 1, the length from the deepest part of the insertion groove 9 to the center of the protrusion 12 is 6, and the depth of the insertion groove 9 is D2, T-work: h1+D2, Di> T2,
L,=1. , h1=rXL4<L3, L4<L5<L3
, h3〈to, h, #h, ,, folk≧h, and when the siding boards are connected, the protrusion is on the back side of the insertion edge 6 and comes into contact with the end of the backing material 16, and the protrusion A gap is formed on both the left and right sides of the joint 12, and the elasticity of the insertion edge 6 strengthens waterproofness and engagement force, and the side surfaces of the bulging part of the joint part are connected so as to be in close contact with each other.

Of course, the dimensions of each part are adjusted so that the decorative surfaces of the connected boards are flush.

Moreover, when constructing the siding board, the back surface material 16 is smooth, so the construction is smooth.

Next, the mounting state of the siding board according to the present invention will be explained using FIG. 2.

First, the siding board P1 is placed on the furrow A, and its extension 11 is fixed to the furrow A through the stitches.

Next, the insertion edge 6 of the siding board P2 is inserted into the insertion groove 9 of this siding board P1, and the extension part 11 of this siding board P2 is fixed to the furring edge A through the stitches.

Therefore, when forming a wall or the like, this operation can be repeated one after another.

Therefore, as is clear from the drawings, since the siding boards are configured in the shape according to the present invention, when the siding boards are connected, the surface material does not come into direct contact with the rim at the connecting portion.

That is, a highly heat-insulating, air-impermeable synthetic resin foam is interposed between the surface material and the rim.

■Elastic curved tongue piece 1 of siding board P1
3 and the synthetic resin foam 15 of the siding board P2 directly contact each other under a certain elasticity.

The rim and the facing are therefore separated by a completely sealed connecting band of highly thermally insulating layer.

(2) When the tip of the insertion edge 6 is bent twice, it comes into elastic contact with the insertion groove, so it has primary waterproofing, heat insulation, and soundproofing functions.

It has the following structural characteristics.

In other words, the highly insulating and impermeable synthetic resin foam and the elastic (springback effect) curved impermeable tongue piece 13 are airtightly connected to each other with a certain force balance. Since it functions as a backing material and makes surface contact with the siding board, it allows air to circulate between the inside and outside from the connecting part of the siding board.
Since heat conduction can be almost completely blocked and heat shielded (insulated), gaps are formed on the left and right sides around the protrusion, and a wall with high heat insulation properties and elastic engagement can be formed.

■Waterproofing and soundproofing are achieved primarily by the surface materials, and secondarily (essentially) by the synthetic resin foam, so there is no corrosion of structural materials or noise problems.

Furthermore, the synthetic resin foam itself has high heat insulation properties and does not absorb moisture, so no deterioration of heat insulation performance occurs.

In addition, the continuous band of synthetic resin foam blocks the circulation of air inside and outside, as well as the conduction of heat (including radiation and convection).
There is little occurrence of dew condensation, and there is no corrosion of insulation materials and construction materials.

In addition, since the e-synthetic resin foam is continuously installed during panel construction, anyone can easily perform the construction.

As mentioned above, the siding board according to the present invention has great features such as excellent heat insulation properties as shown in (1) to (e) above.

Furthermore, since the synthetic resin foam penetrates the nail with an elastic backing, condensation and the like will not corrode the nail itself.

Furthermore, since the tongue pieces function like springback, the connection between the siding boards is strengthened.

In addition, the back material is adhered to the middle of the back of the insertion edge, and the protrusion is brought into contact with this part, making it more airtight than contact between steel plates. The feature is that the contact between the back surface material of the parts and the bulging parts of the joint parts adds more elasticity to the contact parts, improving the engagement force and airtightness.
