External-formwork cast-in-place concrete composite external wall external thermal insulation system
The invention relates to an external-formwork cast-in-place concrete composite external wall external thermal insulation system. The system comprises a composite thermal insulation board and connecting and fixing pieces. The composite thermal insulation board comprises a primary formwork, a thermal insulation layer and a secondary formwork, pulling and tying holes are formed in the outer side of the primary formwork, trapezoidal grooves A are formed in the surface, contacting with concrete, of the secondary formwork, the thermal insulation layer is adhered between the primary formwork and the secondary formwork through adhesive, and the connecting and fixing pieces connect and reinforce the composite thermal insulation board, a reinforcing mesh and the inner formwork in sequence. The invention further relates to a construction process of the external-formwork cast-in-place concrete composite external wall external thermal insulation system. The system has the advantages that the system can be used as the A-class fireproof thermal insulation board, is cast together with a frame structure by connection of the fixing pieces and meets the technique requirements of synchronous design, construction and inspection and acceptance; the system is lightweight, high in strength, good in thermal insulation effect and easy to install, thereby being convenient to construct, low in cost, good in thermal performance and free of potential risk; meanwhile integration of thermal insulation and the building structure is realized.
