Description

[Detailed Description of the Invention] The present invention relates to an architectural panel that can be used as an exterior material for buildings and structures, and which can be easily formed as an exterior wall by a dry method, and which does not come off from the mold or leak even under strong winds.

As a conventional exterior material of this kind, for example,
No. 5, Utility Model No. 53-92918.

In particular, the latter exterior plate has a structure that further strengthens the connection between the connecting parts of the exterior plates.

However, this exterior board had the disadvantage of lacking accents on the entire exterior wall because the joint width was zero.

In addition, since the connecting parts of this exterior plate are in close contact with each other, there are disadvantages such as moisture such as rainwater remaining and corroding the metal under adverse conditions such as high summer temperatures and rainy season.

In order to eliminate these drawbacks, the present invention utilizes the connections of conventional connection structures and provides the required joint width and elasticity to the connection parts, making it stronger and preventing the accumulation of rainwater, etc. Provide architectural boards.

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

FIG. 1 is an explanatory diagram showing the above-mentioned panel, and 1 has a main body and a square or rectangular decorative surface 1a.

The most suitable material for this material is a moldable plate such as a thin metal plate or a synthetic resin plate.

Reference numerals 2 and 3 are side walls, and both ends of the main body 1 are bent vertically, and small protrusions 2a and 3a are formed in the middle thereof in a relationship as will be described later.

Reference numeral 4 denotes a male connecting portion, which is formed from an insert edge 5 that projects outward from the edge of the side wall 2 and a tongue piece 6 that is bent inwardly or outwardly at its tip.

Reference numeral 7 denotes a female connecting portion, which bends the edge of the side wall 3 inward in a U-shape to form an insertion groove 8, and its lower edge 9 is further extended outward to form an extension portion 10, midway therebetween. Projection 1 provided parallel to side wall 3
1 and a tongue piece 12 with the tip of the extension part 10 bent outward.

Note that the protrusion 11 is provided as necessary, and can also be made to protrude in the opposite direction to that shown in the figure.

In particular, the protrusion 11 functions to provide airtightness and drain water when the male and female molds are connected.

Numeral 13 is a synthetic resin foam that fills the gutter-like part formed by the main body 1 and the side walls 2 and 3, and is mainly used as a heat insulating material, an adhesive, a lightweight raising material, a cushioning material, a sound absorbing material, and a non-moisture absorbing material. Acts as a layer.

Examples of this material include polyurethane foam, polyisocyanurate foam, phenol foam, vinyl chloride foam, polyamide foam, polyethylene foam, polyimide foam, etc., and foams are mainly produced from raw materials.

14 covers the back side of the synthetic resin foam 13 with a waterproof sheet, and when forming the synthetic resin foam on a part of the back side of the insertion edge 5 and a part of the back side of the lower edge 9, due to its self-adhesive property. Form into one piece.

The material for the waterproof sheet 14 is a waterproof sheet laminated with one or more of asbestos paper, kraft paper, gypsum paper, synthetic resin film, and nonwoven fabric, or a moldproofing agent is applied to the outer surface of these sheets, such as metal. These include waterproof sheets coated with soap, phenylacetic acid, mercury, phenolic compounds, aniline derivatives, benzimidazole derivatives, sulfur compounds, sanicilanilide, etc.

Further, as the waterproof sheet 14, a sheet coated with polyethylene resin, a flocked sheet, or the like is used.

Here, to explain the small protrusions 2a, 3a in detail, let A and B be the heights from the lower edge 9 on the back surface of the insertion edge 5 to the center of the small protrusions 2a, 3a, A>B.

If the height from the back of the insertion edge to the decorative surface 1a is H,
H = A + 3 to 5 mm, the protrusion width of the small protrusion is ΔS1. If the joint width when the panels are connected is N, then 2ΔS>N, N≧
There is a relationship of .DELTA.S, and the contact surfaces of the small protrusions 2a and 3a are connected with each other in a state where elasticity is applied to each other (for example, as shown in FIG. 2).

In addition, 15 is a furring and 16 is a nail.

Furthermore, the small protrusions 2a and 3a are provided parallel to the edge of the decorative surface 1a.

Further, the cross sections of the small protrusions 2a and 3a are formed as shown in FIGS. 3a to 3d.

In other words, figure a is an acute angle, figure b is a semicircle, figure C is trapezoidal, and figure d is a trapezoid.
The figure shows the deformed shape of a sawtooth.

Next, examples will be described.

Now, it is assumed that the construction panel shown in FIG. 1 is manufactured using the apparatus shown in FIG. 4.

In the figure, A indicates an upper and lower mold a1. which rotates in the direction of the arrow. a
B is a molding plate of the main body 1, and C is a foamable synthetic resin raw material discharger.

Therefore, the main body 1 is a 0.27 mm colored iron plate, and the synthetic resin raw material is polyurethane resin (Daiichi Kogyo Seiyaku's A
Z system), kraft paper (1
909/rd) laminated with polyethylene resin.

For example, mold A rotates at a speed of 30 m/min, the mold temperature is set to 60°C, and the main body 1 is molded with the above raw material.
Suppose that the liquid is discharged onto the back surface 1b of the camera in a somewhat average manner.

During the cream time or gel time period,
Preferably, at the end of the gel time, the waterproof sheet 14 is brought into contact with the raw material as shown in FIG. 4, fed into the mold A, cured in the mold A, and continuously sent out from the outlet as the panel shown in FIG. 1.

FIG. 2 shows the constructed construction panel manufactured in this manner.

As is clear from the figure, the male and female connecting parts and the small protrusion 2a
, 3a has a synergistic effect of fitting and elasticity, so there is no separation and the wall surface has a wide joint.

What has been described above is only one embodiment of the construction panel according to the present invention, and as shown in FIG.
can also be formed as shown in the figure.

As mentioned above, according to the architectural panel according to the present invention,
It is characterized by being able to prevent separation of the connecting portion in the male/female type connecting structure by making the connection via elasticity, and to prevent rainwater from leaking into the interior from the connecting portion.
