Study on the Techniques of Exterior Wall External Insulation with Cast-in-place Concrete to Super High Residential Buildings

摘要

The newly-suggested energy saving system to exterior wall external insulation is introduced in the paper. It was found that the connecting firmness between the planted rods, and the net of the reinforced steel rods and plates, and the plastering techniques can eliminate the stress deformation and cracks caused by the changes of temperatures. For the first time the theory of weight-share on layers to exterior wall heat preservation is put forward and applied, the method of which efficiently solved the four key technical problems to heat preservation system of the exterior wall. The examples in projects is also stated, and it was concluded that the new system is safe to apply, easy to operate, economy and efficient. It has been proved by tests that the energy-saving rate in construction reached 65 % . Therefore it is suitable for different kinds of constructions such as tarracks, border sentry posts, perpetual defence works and, industrial and civil buildings.
