Building external wall thermal insulation construction quality safety measures analysis Xinhua Zhang1,a, Jianxin Liu2,b, Hongzhuan Zhang3,c 1Shanghai Normal University, college of Civil Engineering, Shanghai 201418, China 2,3List all distinct addresses in the same way a-c zhxh152@shnu.edu.cn, 13162557029, 0086-021-57125262 Keywords: External thermal insulation; The construction technology; Quality; safety Abstract: The external wall thermal insulation technology in building energy saving is widely used in engineering, but in general it faces some quality security problems, this paper insulation material selection, exterior insulation system and its safety, fire redundancy and external wall construction corresponding measures on the analysis.
So as to the engineering quality safety problems have prevention in the role of the external wall thermal insulation technology obtain the considerable development.
But as a result of external thermal insulation technology development in the initial stage is not mature, such as surface cracks, empty drum phenomenon, wall body peeling off and many other defects, in this paper the problems in construction engineering and the corresponding technical measures for some paper.

(2) the diffusion of shear strain along radial direction of anchorage structure is linear, as shown in Fig.6. (3) the cracks generated mostly in grout and the second interface have five kinds: crack No.1 named as punching failure was formed in the medium; crack No.2 named as debonding failure was generated on second interface; crack No.3 named as tension failure,which was difficult to be observed in field test or practical engineering
