Description of the Related Art Conventionally, panels have been used as partitioning materials for exterior and interior materials of buildings and structures, but in many cases, as shown in FIG. 4 and 4a, the back member 2 is formed in a cross-sectional shape that can be fitted thereto, and the core member 3 is filled between the front member 1 and the back member 2. In this panel, which does not require fire resistance, the surface material 1 is a metal plate, the core material 3 is an organic material such as urethane foam resin, and the back material 2 is paper, aluminum laminate. It is on paper. In addition, depending on the panel, the back material 2 is formed in a gutter shape,
In some cases, fitting portions 4 and 4a are provided.

用されている。On the other hand, the surface material 1 and the back surface material 2 used for fire-resistant applications are both metal plates, and the core material 3 is also a gypsum board.
When an inorganic material such as a calcium silicate plate or rock wool is used and an organic material is used, a flame-retardant material such as a foamed phenol resin is used. Here, as the metal plate, a plated steel plate having a thickness of 0.2 to 2 mm, a painted steel plate, a stainless steel plate, or an embossed plate thereof is used.

４、４ａが開くので、耐火性が劣る。Among such panels, a fire-resistant panel used for fire-resistant applications is one in which a hard core material such as a gypsum board or calcium silicate plate is used for the core material 3 so that it is less deformed in a fire. This is excellent because no reinforcement of the fitting portions 4 and 4a is required. However, since it is very heavy, much labor is required for transportation and construction. On the other hand, a material using rock wool or foamed phenol resin for the core material 3 is lightweight, but the surface material 1 is deformed in the event of a fire and the fitting portions 4, 4a are opened, so that fire resistance is reduced. Is inferior.

耐火性がまだ不十分であった。In order to prevent this, a gypsum board or calcium silicate plate is extruded into the fitting portions 4, 4a of the surface material 1 by extrusion or grinding.

Since the fitting portion usually slightly fluctuates at the time of molding, it does not adhere to both end surfaces of the core material 3, and a reinforcing material having a fixed length is added by butt-inserting, so that a gap is generated.
Fire resistance was still insufficient.

In the panel in which the core material was filled between the surface material and the back surface material, the core material on both sides of the fitting portion was made of a glass fiber laminated material bonded with an organic resin. The panel is manufactured by applying an organic resin while simultaneously transporting a plurality of glass fibers and long fibers, bonding the glass fibers in a bundle, and then forming a gutter-like shape provided with fitting portions on the left and right. The surface material or the back surface material is filled into the fitting portion side, and then the core material between both fitting portions is filled.

If the glue is filled, it can be brought into close contact with the inner surfaces of both fitting portions, so that the surface material is not easily deformed. For this reason, the panel is more excellent in heat resistance than a panel filled with a non-rigid rock wool or foam phenol resin core material. When the ratio of the organic resin in the laminated material is increased, the heat resistance is reduced.

は長繊維を使用するので、継ぎ目が生じない。The filling of the glass fiber laminated material bonded with the organic resin into both fitting portions of the front surface material or the back surface material is performed by applying a curable organic resin while simultaneously transferring a plurality of glass fibers and long fibers. If the process is performed after each glass fiber is formed into a bundle, it can be continuously filled at the same time as the formation of the long surface material or the back surface material, so that the productivity is excellent.
In addition, the glass fiber bonded with an organic resin can be easily deformed before the hardening of the curable organic resin. There is no gap between the surface material and the back surface material due to the adhesive action of the organic resin. Further, since long fibers are used for the glass fiber, no seam is formed.

Thermosetting resins such as phenol resin, melamine resin, epoxy resin and the like are preferable, and phenol resin having high flame retardancy is particularly preferable. The phenolic resin is preferably a resin type obtained by polymerizing phenol and formalin in the presence of an alkali catalyst. This is because when a strongly acidic curing agent (for example, phenolsulfonic acid, paratoluenesulfonic acid, xylenesulfonic acid, etc.) is added and stirred, self-curing is caused by the heat of reaction, and external heating is not required. If a foaming agent is added, a foam can be formed by heat of reaction.

Excellent productivity. As long fibers, those having a C glass composition and an E glass composition are generally commercially available, but the latter having a high softening point is desirable here.

Fill the core material and cover the back material.
