Thermal insulation system for cantilever beam

The utility model relates to the technical field of building engineering construction, in particular to a suspended pouring beam heat preservation system and a suspended pouring beam heat preservation process. And meanwhile, a flame-retardant polyurethane foam material prepared by mixing a polyurethane foaming agent and a flame retardant is sprayed on the surface of the outer side of the template to form a thermal insulation layer. The thermal insulation layer supporting framework is arranged in the thermal insulation layer, so that the thermal insulation formwork has the function of preventing the thermal insulation layer sprayed on the outer side surface of the formwork from falling off, and the technical defect that in the prior art, a thermal insulation body formed by materials such as polyurethane foaming agents and the like is directly sprayed on the outer side surface of the formwork, and consequently the thermal insulation body is prone to falling off is effectively overcome. 本实用新型涉及建筑工程施工技术领域，特别涉及一种悬
