In the building components of the steel structure, especially in the bridge construction of the steel structure, the riveting pieces are generally adopted for connection, but bolt pieces are not directly adopted, the aim is to prevent the loosening and falling of the riveting pieces, ensure that the components have certain anti-seismic requirements, and avoid the brittle deformation or fracture of the connecting pieces caused by excessive rigid connection. However, since the common riveting member realizes connection by means of self deformation or interference, the deformation has uncontrollable property, the cap body after riveting at each time can not meet the requirements of complete coverage and water prevention of the through hole, and the irregular cap body deformation easily leaves a corrosion space for liquid such as water molecules or other foreign matters, so that the connection reliability is reduced. Therefore, it is necessary to design a new type of anti-seismic connector having a waterproof function.

Preferably, the outer surface of the umbrella-shaped structure is an arc-shaped curved surface with a high middle part and a low periphery, and the inner surface of the umbrella-shaped structure is an inner concave surface so as to form a gap with the surface of the connected object.
Preferably, the length of the threaded hole of the screw cylinder connecting part is matched with the threaded section of the screw rod connecting part.
Preferably, the umbrella-shaped structure has a diameter larger than that of the barrel connection portion.
Preferably, the groove at the top of the umbrella-shaped structure is a straight groove, a cross groove or an inner hexagonal groove.
The invention has the advantages that: according to the invention, the cap body is designed into the umbrella-shaped structure with the bevel sharp edge at the edge, when the cap body is connected, the umbrella-shaped structure can be tightly buckled and matched with the surface of an object to be connected, so that good waterproof performance is achieved, liquid such as water molecules or other foreign matters are prevented from entering the connecting hole, the umbrella-shaped structure and the edge of the umbrella-shaped structure can deform when the cap body is used, prestress in interference fit is formed, the cap body is matched with the prestress spring arranged in the connecting part of the screw cylinder, good anti-seismic requirements can be met, and connection looseness is prevented.
