The present disclosure relates to the technical field of building construction, in particular to a free-expansion deformation seam structure applied to a floor.
In addition to relative displacement caused by expansion caused by heat and contraction caused by cold due to temperature change, a building may also produce relative displacement due to external forces such as land subsidence, inclination, and earthquake. In order to protect the building from damage due to relative displacements, extension seams are usually reserved in a floor, a wall, a suspended ceiling, etc. of the building. In order to be beautiful, it is often necessary to cover the expansion seams. People usually call a facility covering the expansion seams a deformation seam. The deformation seam divides a concrete structure into several units, and needs to be sealed by relevant practices in order to meet the requirements of beauty, applicability and safety.
