Expansion joint structure used between floor slabs
The invention provides an expansion joint structure used between floor slabs. The expansion joint structure comprises a floor slab base, a gap formed between the two floor slabs on the floor slab base, and a stainless steel cover plate arranged at the upper end of the gap, and further comprises two first bases and two second bases, wherein a sunken hole I is formed in the inside of each first base; a sunken hole II is formed in the inside of each second base; the first bases are separately arranged on the two sides of the gap; the back surface of each first base is propped against the end surface of the floor slab adjacent to the first base; the lower end part of each first base is embedded in the floor slab base; first countersink screws penetrate through the sunken holes I to fix the first bases on the floor slab base; screw caps of the first countersink screws are positioned in the sunken holes I in the first bases. The two sets of first bases and second bases are respectively corresponding to different floor slabs, and even if the floor slab base below the two floor slabs deforms or the sinking amplitudes are inconsistent, mutual influence of the floor slabs is avoided.
