Cause analysis of cracks in old buildings with elevators in Harbin

The reasons for the cracking of the old building with elevator in Harbin are structural problems, building foundation problems and elevator construction problems.

1. Structural problems of the building: the bearing capacity may not be considered if the elevator is not installed in the old house, or it may not conform to the modern building code. At this time, in order to make the elevator installation feasible, it is necessary to strengthen the building structure, which may affect the original structure and lead to cracking.

2. Building foundation problems: The building foundation may not be firm enough, or the foundation project is not constructed according to the standard, which leads to problems such as settlement and displacement of the foundation, which leads to building cracking.

3. Construction problem of installing elevator: During elevator construction, the original structure may be vibrated. Improper construction or failure to take corresponding measures may damage the building structure and lead to cracking.
