Insulation panels and their manufacturing methods

Abstract

To provide an insulating surface material and a method for manufacturing it that are excellent in terms of appearance and manufacturability. [Solution] The heat insulating surface material 100 comprises a precast concrete slab 10, multiple rows of truss reinforcement bars 20 extending laterally from one wide surface 12 of the precast concrete slab 10, wooden boards 30 in contact with each top 23 of the multiple rows of truss reinforcement bars 20, and a heat insulating material 50 provided in the gap 28 between the precast concrete slab 10 and the wooden boards 30 to embed the multiple rows of truss reinforcement bars 20.

Claims

1. Precast concrete panels and Multiple rows of truss reinforcement extend laterally from one of the wider surfaces of the aforementioned precast concrete slab, A wooden board is in contact with each of the tops of the multiple rows of truss reinforcement, An insulating surface material characterized by having an insulating material provided in the gap between the precast concrete slab and the wooden slab so as to embed the multiple rows of truss reinforcement.

2. The thermal insulation surface material according to claim 1, characterized in that the precast concrete panel and the wooden panel are fastened together by fasteners that straddle the thermal insulation material.

3. The precast concrete slab has an insert with a female thread embedded in it, with the end opening of the insert facing the one wide surface. The fastener is a shaft member having a male screw at at least one end and a head at the other end, The heat insulating surface material according to claim 2, characterized in that a through hole with a counterbore groove at one end is provided in the woodblock at a position corresponding to the insert, the male screw of the shaft member that passes through the through hole is screwed into the female screw, and the head of the shaft member is housed in the counterbore groove.

4. The thermal insulation surface material according to claim 1, characterized in that the thermal insulation material is formed from one of the following: sprayed polyurethane, glass wool, or rock wool.

5. The truss reinforcement comprises two lattice reinforcements extending in a wavy manner in an inclined position, and a straight upper chord member. The thermal insulation surface material according to claim 1, characterized in that the upper chord material is connected to both peaks of the two lattice reinforcements so that the whole is a single unit.
