The insulation board body includes a first metal plate, an insulation core plate and a second metal plate which are arranged in sequence from the outside to the inside. The first ends of the first metal plate and the second metal plate are bent inward to form a groove structure together with the first end of the insulation core plate; the second end surfaces of the first metal plate, the insulation core plate and the second metal plate are arranged flush to form a convex structure together, and the convex structure is engaged with the groove structure so that a plurality of insulation board bodies can be spliced ​​end to end in sequence to form a closed structure.

[0022] The insulation board body is an arc-shaped plate structure formed by sequentially connecting a first metal plate, an insulation core plate and a second metal plate, which improves the structural strength and stability of the insulation board body and also improves its insulation performance.

[0023] In addition, the first ends of the first metal plate and the second metal plate are bent inward to form a groove structure together with the first end of the insulation core plate, and the second end of the insulation board body is arranged flush to form a raised structure, so that multiple insulation board bodies can be spliced ​​end to end in sequence, and a closed structure can be quickly formed without additional auxiliary structure through the interlocking cooperation of the raised structure and the groove structure, thereby simplifying the installation process and reducing installation costs. Moreover, after installation, the insulation board does not need to rely on the wall to maintain the stability and integrity of the structure, further improving the overall performance and stability of the insulation board, and has broad application prospects and promotion value in the construction industry.

[0024] Furthermore, the first metal plate and the second metal plate include but are not limited to other metal materials such as aluminum plate and iron plate.

[0025] The thermal insulation core board includes but is not limited to thermal insulation material boards with thermal insulation function such as polyurethane thermal insulation board and polystyrene board.
