Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, 2, 3 and 4, the waterproof structure for the expansion joint of the building structure comprises a concrete base layer 1, the outer walls of the concrete base layer 1 on the left and right sides are uniformly coated with glass cement and are bonded with the inner wall of a soft cladding layer 2 through the glass cement, the soft cladding layer 2 is made of chloroprene rubber, the thickness of the soft cladding layer is 1 cm, the texture is soft, the wear resistance and the corrosion resistance are high, the cross section of the soft cladding layer 2 is C-shaped, pressing plates 3 are respectively arranged at the upper end and the lower end of the soft cladding layer 2, protruding strips 4 are arranged at the upper end and the lower end of the soft cladding layer 2, the soft cladding layer 2 and the protruding strips 4 are an injection molding integral body, inner grooves 5 are symmetrically arranged at the left side and the right side of the inner corresponding end of the pressing plates 3, the protruding strips 4 are positioned in the inner grooves 5, the upper side of the inner wall of the inner grooves 5 is provided with pressing protrusions 6, the cross-section of inside groove 5 is isosceles trapezoid, and the cross-section of embossing 6 is isosceles trapezoid, and at this moment pressing against of embossing 6, the upside of sand grip 4 is recessed, and sand grip 4 transversely expands outward, and the lateral wall compresses tightly the left and right sides at the inner wall of inside groove 5 about sand grip 4 to make pressure strip 3 and soft covering 2 cooperation department have good water pressure resistance and leakproofness.
