Description

[Detailed Description of the Invention] The present invention relates to a construction panel useful for forming the outer walls of buildings and structures by a dry method.

The mainstream energy saving measures in recent construction are:
The main focus is on insulation structures.

One of the main structures is one made of metal siding with insulation.

In particular, among metal siding materials, those that use synthetic resin foam such as polyurethane foam as the core material are particularly sensitive to the foam distribution density, the directionality of the air bubbles, the material and shape of the front and back materials, and the fixing structure of both surfaces. As a result, the decorative surface of the metal siding material changes into a concave or convex shape.

This is thought to be largely related to the physical properties, shape, and mounting structure of the backing material.

In addition, the amount of raw material used for the core material is small, it can be effectively foamed, and there are no areas where the foam is not present where the backing material and the foam are bonded, and the bonding between the surface material and the backing material is ensured. In addition, it is desirable that the foaming agent provides cushioning properties between the foam and the foaming surface during the foaming of the core material, and that the gas of the foaming agent is allowed to escape to the outside without adversely affecting the foamed structure.

Furthermore, the heat insulating structure must not only be airtight, but must also be designed to prevent condensation caused by the relative relationship between temperature and humidity.

As a countermeasure against this, generally appropriate ventilation is required.

However, conventional building materials of this type have been lacking in this respect.

Furthermore, condensation not only corrodes the rim and other parts, but also causes mold.

The present invention was devised in view of these points, and its main objectives are: ■ Preventing dew condensation by forming ventilation channels after construction, and preventing mold growth using a mold inhibitor, ■ Reducing the amount of raw materials used, ■
Strengthening of mechanical strength, ■ Preventing foaming agent from staying in the foam tissue and preventing swelling of the backing material, ■ Improving sound absorption, ■ Adding cushioning properties to the contact surface with the body rim, etc., ■ Adding elasticity to the attachment part. We propose architectural panels that exhibit the following properties.

The architectural panel according to the present invention will be explained in detail below using the drawings.

FIG. 1 is a perspective view showing an example of the above-mentioned panel. The main body 1 has a rectangular decorative surface 1a and is made of a moldable plate such as a thin metal plate or a synthetic resin plate.

Reference numerals 2 and 3 denote side walls, which are formed by bending both ends of the main body 1 vertically or at an angle (not shown), and the edges of the side walls 2 protrude outward to form a male connecting portion 4.

The male connecting portion 4 consists of a tongue piece 6 whose tip end with the insertion edge 5 is bent as shown in the figure or bent to the opposite side (not shown).

Reference numeral 7 denotes a male connecting portion, which is formed by bending the edge of the side wall 3 inward in a U-shape to form an insertion groove 8, and an extension portion 10 extending the lower edge 9 further outward; It consists of a protrusion 11 provided parallel to the side wall 3, 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 has the function of airtightness and draining 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.

The materials include polyurethane foam, polyisocyanurate foam, phenol foam, vinyl chloride foam, polyimide foam, polyethylene foam, and polyamide foam, and foams are mainly produced from raw materials.

14 is coated with an antifungal agent 14a on the surface exposed as the back side of the waterproof sheet panel, and a plurality of protrusions 15 are formed at appropriate intervals P in parallel with the longitudinal direction of the sheet to improve the strength and composition of the panel itself. It acts to prevent the generation of voids on the top surface in the foaming direction during the formation of the resin foam and to improve the effective expansion ratio of the raw material, and the vaporized gas of the blowing agent is applied to the top surface in the foaming direction of the synthetic resin foam 13 and the back surface of the waterproof sheet. The protrusions 15 have a cross-section of, for example, the second Form as shown in Figures a to C.

In addition, for example, Wt=3~8WInXh=1~8m77I
Xd=3 to 5 φ, W2=5 to 10TrrIrL.

The material for the waterproof sheet 14 is a waterproof sheet laminated with one or more of gypsum paper, asbestos paper, kraft paper, synthetic resin film, metal foil, and nonwoven fabric.

The anti-mold agent 14a is, for example, a waterproof sheet coated with metal soap, phenylacetic acid, mercury, phenol compounds, aniline derivatives, benzimidazole derivatives, sulfur compounds, sanicil anilide, or the like.

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

Next, examples will be described.

Now, assuming that a panel as shown in Fig. 1 is manufactured using the apparatus shown in Fig. 3, in the figure A is a heating type mold consisting of an upper and lower mold that rotates in the direction of the arrow, B is a waterproof sheet molding machine, C is a molding machine of the main body 1, and D is a synthetic resin foam discharging machine.

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 Co., Ltd.).
7) AZ system) The waterproof sheet 14 is made of kraft paper (190 y/d) laminated with polyethylene resin.
On top of that, metal soap was applied at a ratio of 209/rd, and in the cross section of ridge 15 in Figure 2 a, P = 10 slope, Wl = 4
rMt, h = 3 rrrm.

For example, assume that the mold A rotates at a speed of 30 rrL/min, the mold temperature is set at 60° C., and the raw material is discharged onto the back surface 1b of the molded main body 1 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. 1, supplied to mold A, cured in mold A, and continuously sent out from the outlet as the panel shown in FIG.

In particular, at this time, the back surface 14a of the waterproof sheet 14 is conveyed to the entrance of the mold A without bending, so the chemical reaction of the raw materials and the foaming height are not suppressed, and at the end of the process, it comes into contact with the foaming top surface 16, resulting in effective foaming. At the same time, the foaming agent that does not contribute to the foaming of the synthetic resin foam is released to the outside without adversely affecting the foam, thereby preventing the formation of voids in the synthetic resin foam and the blistering of the waterproof sheet.

Moreover, an appropriate amount is injected into the connecting portion back surface of the main body 1 and the end back surface 14a of the waterproof sheet 14 to the extent that no peeling occurs during pressing and molding.

When we cut the architectural panel manufactured there and observed its cross section, we found that the synthetic resin foam 13 had a homogeneous foam structure (
(closed cell), and the density was the same as that of the top surface of free foaming which was slightly compressed.

Further, the main body 1 and the waterproof sheet were integrally formed of the synthetic resin foam 13, and the ends of the waterproof sheet and the back surface of the connecting portion were sufficiently adhered.

Furthermore, when this construction panel is installed as shown in FIG. 4, for example, when it is installed on the rim 17, a ventilation passage 18 is formed, and there is no condensation or mold, and the rim 17
7 will not corrode.

What has been described above is only one embodiment of the construction panel according to the present invention, and flame retardants and inorganic porous particles can also be added to the synthetic resin foam.

Furthermore, as shown in FIG. 5, the synthetic resin foam 13 may be shaped and a waterproof sheet 14 may be attached to the back surface thereof.

Further, the waterproof sheet 14 can be formed as shown in FIGS. 6a and 6b.

In other words, Figure a shows a waterproof sheet with a synthetic resin sheet that melts due to the heat of reaction during the formation of the synthetic resin foam attached to the back surface, and Figure B shows a waterproof sheet with small holes 19 in the convex parts or in the entire surface (not shown). This is a waterproof sheet installed.

In addition, the convex portions may be formed in a random wrinkle shape as shown in FIG. 7, or the concave portions 15a may be formed only at the ends of the waterproof sheet 14 as shown in FIG.

As mentioned above, according to the architectural panel according to the present invention,
It has the characteristics of sufficiently exhibiting the effects of (1) to (4) described above, and has the advantage of being easy to manufacture and being manufactured at low cost.
