Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction, in particular to a free expansion joint structure suitable for floors. BACKGROUND

[0002] In addition to the relative displacement of the building due to thermal expansion and contraction caused by temperature changes, the building may also produce relative displacement due to external forces such as ground subsidence, tilting and earthquakes. In order to protect the building from damage due to relative displacement, expansion joints are usually reserved in the floor, wall, suspended ceiling and other parts of the building. In order to be aesthetically pleasing, the expansion joint is often covered. People usually refer to the facilities that cover the expansion joint as deformation joints. Deformation joints divide the concrete structure into several units. In order to meet the requirements of aesthetics, applicability and safety, the deformation joint needs to be closed using relevant methods.

[0003] The concrete structure includes a floor slab and a surface layer. The traditional deformation joint is composed of two bases and a middle cover plate. The two bases are both open type and are arranged parallel to the long direction of the deformation joint. The bases are fixed to the floor slab as a whole by expansion bolts. Then the middle cover plate is inserted from one side and completely inserted into the base slot. Under the action of external forces such as temperature and earthquakes, the cover plate deforms and resets in the slot.

[0004] In the traditional deformation joint, the cover plate deforms freely in the base slot. The top of the base is easily deformed by the load of personnel walking and object carrying, and the surface is severely worn. When the surface is severely worn, the base needs to be replaced. The base replacement requires the removal of the middle cover plate and the removal of the original expansion bolts, which is relatively complex. In addition, the two sides of the base are higher than the cover plate, and the cover plate is easy to accumulate stains during long-term use, and the accumulated sewage is not easy to clean when wiping the floor.
