Construction Technology of Joint Sealant for Exterior Wall of Prefabricated Concrete Buildings
The construction of concrete building exterior wall joint sealing is an important link in the construction process of prefabricated building,which has an important impact on the construction quality of the whole building.Based on the introduction of the general situation of the prefabricated building project,the types and properties of the common sealant are analyzed,and the MS sealant is selected for the construction of the external wall joints.During the construction of sealant,the backing material should be filled into the wall joint and the beautiful paper should be pasted on the surface of the external wall before the construction of sealant can be carried out.The relevant construction technology is introduced from the deepening design,joint cleaning,backing material filling,sealant construction and other aspects.
