A boltless comb-tooth plate noise-reducing and reinforced expansion joint

Abstract

This utility model relates to the field of double rubber strip expansion joint technology, specifically a boltless comb-tooth plate noise-reducing and reinforced expansion joint, including two symmetrical connecting seats. Several anchor plates are provided on the outer wall of the connecting seats. Each anchor plate on the same side has a slot, and a rubber plate is placed in each slot. A waterstop is also provided between the connecting seats. A positioning plate is provided on the bottom of one of the rubber plates, and a stainless steel plate is provided above the protrusion for shielding and protection. This boltless comb-tooth plate noise-reducing and reinforced expansion joint uses two connecting seats and multiple anchor plates in combination. The waterstop is fixed between the two connecting seats by rivets and threaded connections. The two rubber plates are engaged by comb-tooth interlocking, increasing the range of expansion and contraction, reducing shelling and affecting connection and use. With the cooperation of the stainless steel plate, the T-shaped block and the T-slot on the protrusion interlock, achieving the stainless steel plate's interception and protection of the area below the rubber plate.
