[0002] In the field of full-A-class fireproof exterior wall insulation technology, post-pasted A-class rock wool board technology occupies a dominant position. In addition, there is also a method of placing B1-class insulation materials in the sandwich of the exterior wall of the concrete structure, and achieving A-class fireproof performance through the inner and outer concrete layers. However, most of the exterior wall insulation structures of buildings currently still use B-class insulation materials, and set up 300mm high fire isolation belts on the floors, which are cast and constructed together with the main structure. However, the post-pasting technology has the problem that the insulation board is easy to fall off, the construction technology of the sandwich insulation board is complicated, and it may have an adverse effect on the quality of the exterior wall shear wall. At the same time, even if B1-class insulation materials are used and floor fire isolation belts are added, its fireproof performance cannot meet the full A-class requirements.
[0003] At present, the insulation construction in the construction industry is either to post the insulation board after the wall is built, which is easy to fall off; or the construction process of the sandwich insulation board is complicated and cannot be fully promoted. Utility Model Content
