Description

{Construction panel manufacturing apparatus}

The present invention relates to a construction panel manufacturing apparatus, and more particularly, to a construction panel manufacturing apparatus used both as a finishing material for interior and exterior use of a building and as a heat insulating material.

Generally, the interior and exterior finishing materials of buildings are applied to the inner wall or outer wall of a building having a heat insulating material such as styrofoam or urethane foam, and tiles, red bricks, rubble and the like are used.

On the other hand, as described above, the heat insulating material such as styrofoam or urethane foam used before the finish material is applied to the inner wall or the outer wall of the building generally has low density and low strength characteristics, has a disadvantage of being bulky or thick, There is a disadvantage that the interior space of the building is reduced because the wall thickness of the building is increased after being damaged or built.

In addition, when the heat insulation material such as the foamed foam or the foamed foam is applied before the finishing material is applied to the inner wall or the outer wall of the building as described above, the material cost and the labor cost are increased and the construction time is long.

On the other hand, there has been developed a finishing plate for architectural use which is used both as an interior and exterior finishing material for a building and as a heat insulating material.

For example, Patent Document 1 discloses a structure in which a core, a urethane and a film coating layer are formed at both side ends of a groove and a protrusion, respectively, so that they can be fitted to each other, Finishing materials for construction are listed.

The finishing plate for architectural use disclosed in Patent Document 1 has a disadvantage in that it is heavy because it uses a steel plate as a core, and the urethane which is cured after spreading on the core shows still low density and low strength characteristics, and urethane easily breaks There are disadvantages.
