Description

[Detailed description of the invention] This invention relates to a reinforced noncombustible panel.

Noncombustible panels are used for building ceilings, partitions, etc. from the viewpoint of fire prevention.

Noncombustible panels are made by sandwiching glass wool, rock wool, asbestos honeycomb, etc. between two thin face plates, which are adhered to the face plate using a sodium silicate noncombustible adhesive, and the panels are bonded together at the edges. It is conventionally known that a connection panel frame is attached to a bent portion provided at an end of a surface plate by fitting. However, in these conventional products, the soft noncombustible material described above is sandwiched between two thin top and bottom sheets of surface material, which are then bonded to the top plate using a sodium silicate noncombustible adhesive. Therefore, even if the same sandwich-like panel is used, the bending strength and compressive strength of the panel are significantly higher than that of a panel formed by injecting and foaming a hard polyurethane foam raw material resin between two top and bottom face plates. inferior to Therefore, conventional noncombustible panels require additional reinforcement when subjected to bending or compressive loads. In addition, since rigid polyurethane foam is a semi-noncombustible material,
It cannot be used for noncombustible panels.

In conventional noncombustible panels, it is difficult to apply adhesive to the surface of soft glass wool, etc. to bond glass wool, etc. to the top plate, so adhesive must be applied to the panel top plate. Since this panel surface plate has a bent portion for fitting with the panel frame and is not flat, a roll-type automatic coating machine cannot be used. Even if spray painting is done, it is difficult because there are bends, so it ends up requiring hand painting, and it takes a lot of time to apply the adhesive.Also, sodium silicate adhesives are difficult to apply. The problem was that it was weak.
The size of noncombustible panels is limited due to the relationship between the poor workability of adhesive application and the panel strength described above, so the length of noncombustible panels that are generally produced is approximately
The limit was 3m.

This idea is based on conventionally known noncombustible panels.
The reinforced noncombustible panel was developed to solve this problem, and the reinforcing material made of a metal plate is formed into a corrugated shape with corrugated tops on both sides. and a trough, and the wave heads are parallel to each other and are planes with a constant interval.Both sides of the reinforcing material are bent in a direction perpendicular to the wave head to form panel side walls. A fitting part for connecting the panels is provided on the outer surface of at least one side wall, and a surface plate that rubs both the front and back surfaces of the reinforcing material is bonded to the reinforcing material at the crest of the wave.

The reinforced noncombustible panel according to this invention has the above-mentioned structure, and the wave heads on both the front and back sides of the reinforcing material, which is made of a metal plate formed in a corrugated shape, are parallel to each other and have a constant interval. The surface plate that cuts both the front and back sides of the reinforcing material is bonded to the reinforcing material at the crest of the wave.
Since the two face plates are integrated with the reinforcing material, the structure is extremely strong against compression and bending. In addition, since both sides of the reinforcing material are bent in a direction perpendicular to the top of the wave to form the panel side walls, unlike conventional noncombustible panels, the bends provided at the ends of the two thin face plates are The panel frame is attached to the panel by fitting, and the panel strength is greater than that of a panel frame that serves as the panel side wall.

Furthermore, the reinforcing material is made of a metal plate and is formed in the shape of a corrugated sheet, and does not have a complicated shape, so that it can be roll-formed. Furthermore, since the corrugated tops on both the front and back surfaces of the reinforcing material are planes that are parallel to each other and have a constant interval, the adhesive can be applied to the corrugated tops using a roll-type automatic coating machine. Furthermore, since both sides of the reinforcing material are bent to form the panel side walls, there is no need for a panel frame to form the panel side walls, unlike conventional panels. Therefore, the workability of panel production is significantly improved, the production time is shortened, and together with the above-mentioned improvement in the strength of the panel structure, it becomes possible to produce longer panels than conventional noncombustible panels.

Furthermore, as mentioned above, it is possible to use a roll-type automatic coating machine to apply adhesive, so the adhesive can be applied evenly and there is no waste, and only a small amount of adhesive is needed. Even if an organic adhesive is used, a sufficiently strong bond can be obtained without impairing the nonflammability.

Note that the troughs of the reinforcing material can also be filled with glass wool, rock wool, etc. as a heat insulating material.

An embodiment based on this invention will be described with reference to the drawings.
