The fireproof layer is connected to the base wall through an anchor bolt. The upper and lower ends of the fireproof layer are connected to the upper thermal insulation layer and the lower thermal insulation layer through a clamping piece.
[0007] By using the above technical scheme, the anchor bolt and the clamping piece are used to further connect and reinforce the upper thermal insulation layer, the lower thermal insulation layer, and the fireproof layer based on the bonding and fixation, so that the isolation belt is not prone to separation or even peeling from the wall, thereby ensuring the construction quality.
[0008] Optionally, the fireproof layer comprises a plurality of rock wool composite boards stacked in sequence, and the upper thermal insulation layer and the lower thermal insulation layer are both made of polystyrene boards.
[0009] By using the above technical scheme, the rock wool composite boards are used to form the fireproof layer, and the polystyrene boards are used as the upper thermal insulation layer and the lower thermal insulation layer, which has good thermal insulation and fireproof effect.
[0010] Optionally, the rock wool composite boards inside the fireproof layer, and the fireproof layer and the upper thermal insulation layer and the lower thermal insulation layer are all filled with anti-cracking protective layers.
[0011] By adopting the technical scheme, the anti-cracking protective layer is arranged to solve the crack problem between the rock wool composite boards in the fireproof layer and between the fireproof layer and the upper and lower thermal insulation layers, thereby ensuring the overall construction quality.
[0012] Optionally, the anti-cracking protective layer comprises two layers of anti-cracking mortar and a mesh cloth sandwiched between the two layers of anti-cracking mortar.
[0013] Optionally, a first mortar leveling layer is further arranged between the upper and lower thermal insulation layers and the fireproof layer and the base wall.
[0014] By adopting the technical scheme, the first mortar leveling layer is used for leveling before laying the upper and lower thermal insulation layers and the fireproof layer, so as to facilitate subsequent laying construction.
[0015] Optionally, a second mortar leveling layer is further arranged between the upper and lower thermal insulation layers and the fireproof layer and the finishing layer.
[0016] By adopting the technical scheme, the second mortar leveling layer is used for leveling before laying the finishing layer, so as to facilitate subsequent laying construction.

On the basis of bonding and fixing, the upper and lower thermal insulation layers and the fireproof layer are further connected and reinforced by using anchors and clamping pieces, so that they are not easy to separate or even fall off from the wall, thereby ensuring the construction quality.
[0020] 2. The anti-cracking protective layer is arranged to solve the crack problem between the rock wool composite boards in the fireproof layer and between the fireproof layer and the upper and lower thermal insulation layers, thereby ensuring the overall construction quality.
[0021] 3. Before laying the upper and lower thermal insulation layers and the fireproof layer, or before laying the finishing layer, the first and second mortar leveling layers are respectively used for leveling, so as to facilitate subsequent laying construction. BRIEF DESCRIPTION OF DRAWINGS
