Free-expansion deformation seam structure applied to floor

A free-expansion deformation seam structure applied to a floor, comprising:

• a first base (1) and a second base (2), wherein the first base (1) and the second base (2) are fixedly installed on floor slabs (7) on both sides of an expansion seam respectively, the first base (1) is provided with a first clamping groove (141), and the second base (2) is provided with a second clamping groove (241);
• a cover plate (3), covering the first base (1) and the second base (2), wherein a bottom of the cover plate (3) is fixedly connected with a first connection part (31) and a second connection part (32);
• a first telescopic component (4), wherein one end of the first telescopic component (4) is clamped in the first clamping groove (141), and the other end thereof is fixedly connected to the first connection part (31);
• and
• a second telescopic component (5), wherein one end of the second telescopic component (5) is clamped in the second clamping groove (241), the other end of the second telescopic component (5) is fixedly connected to the second connection part (32), and
• the first telescopic component (4) and the second telescopic component (5) are capable of expanding and contracting in a reciprocating mode in a horizontal direction of the expansion seam to drive the cover plate (3) to slide on the first base (1) and the second base (2), wherein
• the first telescopic component (4) comprises a first elastic member (42) and first clamping plates (41) arranged at both ends of the first elastic member (42), one of the first clamping plates (41) is clamped in the first clamping groove (141), and the other of the first clamping plates (41) is fixedly connected to the first connection part (31);
• and
• the second telescopic component (5) comprises a second elastic member (52) and second clamping plates (51) arranged at both ends of the second elastic member (52), one of the second clamping plates (51) is clamped in the second clamping groove (241), and the other of the second clamping plates (51) is fixedly connected to the second connection part (32).
