In the external wall construction of high-rise buildings, due to improper construction operation, the waterproof mortar layer cracks and cracks, empty drums, falling off and other quality problems can be summarized in the following aspects: 1. Stratified plastering is not carried out according to the regulations. Under normal circumstances, waterproof is required. Plastering should be generally divided into 5 times. The construction unit in order to seize the progress, using a live plastering method, plastering thickness is too large. 2. The base is not well handled, the hole hole of the outer frame tube is not blocked several times from the inside to the outside, the hole of the wall bolt left by the concrete wall column and beam during mold installation is not blocked and compacted, and the steel wire mesh is not set between the wall materials of different materials. There is dust and dirt on the wall surface, and the wall is too dry. Before plastering on the wall surface of some dust and dirt and mortar cleaning is not complete, not clean, not in advance of the grassroots sprinkling wet, the wall is in a dry state. In this condition, the construction plastering layer, because the water in the mortar is quickly absorbed by the base, is bound to form a void crack, mortar strength reduced. The proportion of plastering mortar is not accurate. The mortar mark is too large.
