A composite
thermal insulation member of building is provided. It relates to the composite
thermal insulation member of the building, especially the composite
thermal insulation wall body and the composite roof aimed to solve the problem of high cost of the existing energy-saving wall body and the inconvenience of construction, the first structure is the core layer bonded inside the frame with the outer protecting layer provided on the surface of the core layer and the alkali-resistant netting fabric bonded to the outer protecting layer and the load-carrying component, the second structure is the core layer provided between the indoor and outdoor outer protecting
layers and bonded each other, also the steel hoop fixed with the steel bars inside the indoor and outdoor outer protecting
layers, the third structure is the outer protecting layer provided on two sides of the core layer and its upper side and bonded to it, also the core layer and the steel bars arranged inside the outer protecting layer as well as the outer protecting layer wrapped and surrounded by the alkali-resistant netting fabric, the fourth structure is the composite pillar anchored to the main structure and the core layer bonded to the main structure and the light composite pillar with the
composite girder supported on the composite pillar and the plastered outer protecting layer on the composite pillar,
composite girder and the outer side of the core layer, the fifth structure is the core layer provided between the upper and lower outer protecting
layers with the lower outer protecting layer fixed to the girder or wall of the main structure, the invention has the advantages of low cost, convenience of construction etc. which is beneficial to the energy-saving of the construction and the reform of the wall body.
