Analysis and control of multilayer building crevice of brick and concrete structure

This paper analyses and studies the phenomenon of the multilayer building crevice of the brick and concrete structure. According to the crevice shape and place, it can be divided into temperature crevice, unequal sinking crevice and others. According to the several real construction examples it has analysed the reasons for emerged crevice from the sides of construction structure design, project quality and so on. It puts forward the ways to avoid it and some effective remedy measures when it emerges so as to stop its pervasion and improve the safety factor and prolong the service life of the buildings.
