Description

[Detailed Description of the Invention] Fields of Application of C1jT Industry 1~] The present invention provides a multi-purpose construction panel (hereinafter referred to as pile in !ir) useful for forming the walls of buildings and structures. 4. Further details 7 (regarding panels with enhanced fire resistance).

[Conventional technology]

The conventionally used insert panel has a surface made of a thin metal plate (61t on both sides of A, formed into an almost gutter-like shape with #-shaped connecting parts, and polyr-r' in this gutter-like part). / Tanfor J, etc. are filled with a synthetic resin foam as a core material 2 and the back side is covered with a sheet-like material.There are many products on the market because they have heat insulating properties.

[Problem that the invention seeks to solve]

However, in this type of panel, synthetic resin foam (core) 4, such as poly-pretanfor J1, polystyrene foam, etc., does not have heat insulation T'+, "ζ" nor fire resistance +'l, and has a quasi-nonflammability test. It was impossible to pass the fire protection test.

[Failure to solve the problem]

In order to eliminate these drawbacks, the present invention is designed to synthesize a fireproofing sheet I impregnated with a novolac type phenolic resin that foams at high temperatures and forms a carbonized layer with at least the decorative surface portion of the surface material. We propose a panel that is placed between a core material made of resin foam and that forms a fire-retardant layer every 7 seconds after heating at a high temperature, greatly improving its fire-retardant properties. It is something.

〔Example〕

Below, typical examples of the panel according to the present invention will be explained in detail using the drawings. That is, FIG. 1 is a perspective view showing the above-mentioned panel A, and includes, for example, a surface-treated steel sheet, a zinc-nickel alloy plated steel sheet, an aluminum-zinc alloy plated steel sheet (product names: Galfan, Galvalume steel sheet, Super Zinc), and an aluminum plate. , aluminum alloy plate, copper plate, stainless steel plate, clad copper plate, vibration damping steel plate, etc.
A core +4' filled on the surface material made of a seed metal plate (including flat plates and embossed plates) or synthetic resin plate formed by one type of roll, press, or extrusion molding, and on the back side of the surface material. 14, and a sheet-like back material 15 that covers the back surface of the core material 14.

Ru. This decorative surface portion ↓ functions as a decorative surface on the wall formed by panel A, and on both longitudinal edges thereof there are side walls 3.4 bent vertically or inclined.
It has the following. In addition, the male type connecting portion -te is formed from an insertion edge 6 bent toward the lower end of the side wall 3, and a tongue piece 7 formed by bending the tip of the insertion edge 6 into a seam shape as necessary. tf, 1ltfj type connecting portion -6- has an engaging lll!9 formed inwardly in a U-shape at the lower end of the side wall 4, and a lower edge 10 of the engaging groove 9.
It is formed of a nailing piece 11 which extends outwardly, and a tongue piece 12 whose end edge of the nailing piece 11 is bent into a seam shape as required. That is, the panels A are connected to each other by inserting the insertion edges 6 into the engagement grooves 9.

In addition, the tongue piece 7 prevents the tip of the insertion edge 6 from waving and facilitates insertion into the engagement groove 9. This is also useful for strengthening the engagement force by utilizing the elastic deformation of the core material 6.Furthermore, although not shown, the tongue pieces 7.12 clamp the edge of the back material 15, which will be described later, to prevent leakage of the core material 14. At the same time, it is possible to strengthen the mechanical strength of panel A. 13 is a fireproof sheet, which is made of glass fiber sheet, glass wool net, club +
- Mr. i, formed by coating a sheet-like material such as ashest paper, non-woven fabric, rock wool, cloth sheet, etc. with novolac type phenolic resin powder on one side, melting it by applying heat, and cooling it, or Consists of substances mixed in when manufacturing sheet-like products. This fireproof sheet 13 has a core material 14
It is interposed between the surface material and the surface material, especially on the back side of the decorative surface part, either entirely or partially in a band shape, and the phenol foams, for example, 3 to 20 times as much under high temperature conditions such as fire. . That is, by foaming the fireproof sheet 13 under high heat, it becomes an intermediate isolation layer between the core material 14, which has low fire resistance, and the heat source, so that the fire resistance of the panel is dramatically improved.

Further, since the fireproof sheet 13 has a thickness of about 0.5 to 5 mm and is flexible, it can be installed by simply modifying a part of the conventional panel manufacturing equipment. Furthermore, the fireproof sheet 13 may be, for example, a simple sheet shape ((a) diagram) as shown in FIG. In this case, the holes 13a shown in FIGS.

In addition, when the hole 13a is not provided as shown in the fat diagram, it is preferable to stick it to the surface material-1 via an adhesive, although it varies depending on the width of the fire prevention sheet 13 and the material of the core material 14. The core material 14 is filled at least in the gutter-shaped part surrounded by the decorative surface part -3-1 male type connection part] and the female type connection part J- on the back side of the surface material, and mainly provides insulation to panel A. It is made of one or more materials that have secondary functions such as adhesives, noncombustible materials, cushioning materials, and soundproofing materials. Specifically, phenol foam resin is coated around synthetic resin foams, such as polyurethane foam resin, phenol foam resin, polyisocyanurate foam resin, polystyrene foam, and perlite, and this is heated and pressurized to foam. flame retardants, flame retardant aids (borax, sodium borate, antimony trioxide, calcium carbonate, aluminum hydroxide,
It consists of one or more of the following: pearlite grains, whitebait balloons, asbeths), and 1TilHII). Furthermore, although not shown, the core material 14 can be provided to bulge out below the back surface of the nailing piece 11 to further improve the heat insulation properties. In addition, when using a resol type phenol pho J, type synthetic resin for the core 4A14, JIJj fire -1 13 is every other month, and the curing of the resol type phenol pho λ -1. Since the strong acid component used as the agent does not come into contact with the surface element 4-2-, corrosion of the surface 1E1- by the strong acid is prevented.

〔Effect of the invention〕

4- As mentioned above, according to the panel according to the present invention, the novolak type phenolic resin contained in the fireproofing sheet I. foams during high heat such as a fire, making it non-combustible. It becomes an isolation layer between the core material and the heat source, which is lacking in heat, and greatly improves the fire resistance of the panel.
can do. In addition, when using resol-type phenol fume as the core material for fireproof sheets, the strong acid used as a hardening agent for the core material prevents the corrosion of the surface material to prevent the components from coming into contact with the surface. Can be rainproof. Furthermore, for panel manufacturers, we have introduced a mechanism for applying fireproof sheets to conventional manufacturing equipment.
It has the characteristics that only one addition is required and it can be easily manufactured.
