Multiple insulation boards 2 are disposed between each pair of L-shaped insulation boards 1. Concave slots 8 are provided on the side walls of the four L-shaped insulation boards 1 and the side walls of the multiple insulation boards 2. Protruding inserts 9 are fixed to the other side walls of the four L-shaped insulation boards 1 and the multiple insulation boards 2, and are inserted into the concave slots 8. By inserting the protruding inserts 9 into the concave slots 8, the insulation of the two L-shaped insulation boards 1 and the multiple insulation boards 2 can be achieved. The insulation boards 2 are spliced ​​together and between the insulation boards 2 and the L-shaped insulation boards 1. An insulation film 3 is placed on top of the four L-shaped insulation boards 1, and a positioning mechanism 4 is set on both sides of the L-shaped insulation boards 1. By splicing multiple insulation boards 2 between two L-shaped insulation boards 1, and then covering the four L-shaped insulation boards 1 with the insulation film 3, the concrete inside the four L-shaped insulation boards 1 can be insulated. The positioning mechanism 4 can position the insulation film 3 to prevent it from falling off.

[0019] Both insulation board 2 and L-shaped insulation board 1 are made of rigid polyurethane foam. Rigid polyurethane foam is a new type of synthetic material with thermal insulation and waterproofing functions. It has a low thermal conductivity, only 0.022–0.033 W / (m*K), equivalent to half that of extruded polystyrene board, making it the lowest thermal conductivity among all insulation materials. Rigid polyurethane foam is mainly used in building exterior wall insulation, integrated roof waterproofing and insulation, cold storage insulation, pipe insulation materials, building panels, refrigerated truck and cold storage insulation materials, etc.

[0020] Among them, aluminum foil reflective film 7 is fixed on the inner wall of multiple insulation boards 2 and four L-shaped insulation boards 1. The aluminum foil reflective film 7 can reflect the heat emitted by the concrete back into the concrete, thereby further reducing heat loss.
