Abstract

A hinge joint sealing connection device comprises a connection part for connecting two adjacent hollow plates, a filling part filled in the hinge joint and a bridge deck pavement layer laid on the topsurface of the hollow plates. The hinge joint sealing connection device comprises a connection part for connecting two adjacent hollow plates, a filling part filled in the hinge joint and a bridge deck pavement layer laid on the top surface of the hollow plates. The connecting part comprises a plurality of sets of connecting pieces arranged in the hinge joint at intervals along the width direction of the bridge; The connector comprises a connecting plate which is laid on the top surfaces of two adjacent hollow plates and covers the hinge joints along the bridge length direction, and the two ends of the connecting plate along the bridge length direction are fixed on the top surfaces of the two adjacent hollow plates by fixing devices respectively. The connectors also include an upper horizontal connection group, a lower horizontal connection group, and a cross connection group. The filling portion is a first concrete filled in the hinge joint. The pavement layer comprises a concrete layer formed by pouring a second concrete on the top surface of the hollow slab, and the concrete layer is paved with a reinforcing steel mesh which is fixedly connected with the connecting part.

Description

technical field [0001] The invention relates to the field of bridge engineering, in particular to a hinged seam sealing connection device. Background technique [0002] Due to the advantages of prefabricated reinforced concrete or prestressed concrete hollow slab girders with good structural performance, factory production, convenient transportation and installation, and fast construction speed, hollow slab girders are still the most commonly used upper load-bearing members of small and medium-span bridges in my country. In the construction of prefabricated bridges, adjacent hollow slab girders are connected horizontally through cast-in-place groove-and-groove joints, so that multiple horizontally connected hollow slab girders can bear the load together. In order to achieve the purpose of jointly bearing the load between adjacent hollow slab beams, the connection structure of the hinge joints between adjacent hollow slabs is particularly important. In the currently used hol...
