Through the cooperation of the upper and lower two grooves between the adjacent frames, the overlapping installation of the adjacent frames is achieved.

[0022] A number of mounting holes are provided on the frame 3, and fixing bolts 6 are inserted into the mounting holes to fix the adjacent frames, so that the heat insulation body is firmly mounted on the support cross beam.

[0023] The heat insulation body 1 includes a support gasket 7, a first heat insulation layer 8, a strengthening support layer 9, a second heat insulation layer 10, a fireproof layer 11, a waterproof layer 12 and a mesh layer 13. The support gasket 7 is arranged in the innermost layer to support the heat insulation body. The first heat insulation layer 8 is arranged outside the support gasket 7. The strengthening support layer 9 is arranged outside the first heat insulation layer to enhance the support performance of the heat insulation body. The second heat insulation layer 10 is arranged outside the strengthening support layer. By arranging heat insulation layers on both sides, the heat insulation performance is improved. The fireproof layer 11 and the waterproof layer 12 are sequentially arranged outside the second heat insulation layer to achieve the fireproof and waterproof performance of the heat insulation body. The mesh layer 13 is arranged outside the waterproof layer 12. After the heat insulation body is installed, it is convenient to coat paint on the mesh layer, increasing the bonding performance between the paint and the heat insulation body and effectively preventing the coated paint from falling off.
