Description

[Detailed Description of the Invention] The present invention relates to an improvement of a fire-resistant heat insulating panel using phenol foam as a core material.

Phenol foam has the disadvantage of poor toughness and brittleness, so when making a sandwich structure panel using it as a core material, it is necessary to place an inorganic plate or buffer plate between the metal plate used as the surface material for the purpose of protection etc. be.

However, in conventional fire-resistant insulation panels of this type, the phenol foam is exposed at the periphery, especially at the edges where the panels are connected, and even in those that have edge members, the edge members are connected to each other. . For this reason, it has been difficult to avoid problems such as damage to the phenol foam or formation of dents during transportation, and a decrease in heat insulation due to the edge members. Furthermore, in the state where the walls are connected, it is difficult to prevent water from entering the phenol foam from the connecting portions and deteriorating the core material.

The object of the present invention is to provide a fire-resistant insulation panel with a simple structure that overcomes these drawbacks.

To this end, the present invention, in addition to the aforementioned Sanderch structure, attaches a cushioning material to the periphery, and
It is characterized in that the panels are connected using a metal plate as a surface material.

Embodiments of the present invention will be described below with reference to the drawings.

In the embodiment shown in FIG. 1, this fireproof heat insulating panel has buffer plates 2 adhered to the inner surfaces of two metal plates 1, and a core material 3 of phenol foam filled between them. As the buffer plate, for example, a synthetic resin foam or a flame-retardant rubber plate is used. Further, as the inorganic board, for example, a board material such as calcium silicate, perlite, gypsum, or asbestos is used.

The edges of the metal plate 1 are provided with extension portions 1A and 1B for connection at positions that are biased toward the inside of the panel surface position.
have. These extending portions 1A and 1B are formed so that adjacent extending portions overlap each other when the panels are connected, and a groove 4 along the connecting portion is formed by biasing the extending portions. It's getting old.

Further, between the tips or bases of the inner surfaces of the extending portions 1A and 1B of the end edges, cushioning materials 5A and 5B made of the same material as the buffer plate 2 are attached so that both sides thereof are in contact with each other. Here, the cushioning material 5B has a concave shape to receive the cushioning material 5A when connected.

According to such a structure, damage to the core material 3 due to impact from the panel surface, impact from the end face, etc. can be prevented. In addition, when the panels are connected, the connection is held by fixing the extensions 1A and 1B of the metal plates 1 with, for example, rivets 6, making it strong, preventing flame from entering between the joints, and improving fire resistance in the event of a fire. performance is improved. Furthermore, a concave groove 6 along the connecting part
This makes it easy and reliable to apply the caulking 7, and improves the effect of preventing rainwater from entering during normal times. This improves prevention of deterioration of the core material 3.

Figures 2 and 3 show other embodiments, and as shown here, the shape of the cushioning material attached to the edge may be 5', 5''A, 5''B, or any other shape. . In addition, as shown in Fig. 2, the cushioning material 5',
It is also possible to fill the space between the holes 5' with a heat insulating material such as a phenol foam material 8.

As explained above, according to the present invention, with a simple structure, it is possible to prevent damage to the panel core material due to external forces and deterioration due to water intrusion from the edge of the panel, and it has great effects such as improving heat insulation and fire resistance. It will be done.
