Riding-hung bearing structure and construction method of simply supported first and then continuous bridge

Abstract

The invention provides a riding-hanging support structure and a construction method for a simply-supported and then continuous bridge, belonging to the technical field of bridge construction. The ride-on support structure includes a ride-on bracket, a first assembled beam arranged on the top of the ride-on bracket, a sliding support, a lateral pushing device arranged on the first assembled beam, a clamp positioned above the slide bearing, and The deviation correcting device arranged on the first assembled beam and connected with the fixture; the riding bracket is used to be placed on the end of the cover beam; the horizontal pushing device is used to drive the sliding support to reciprocate and slide along the length direction of the first assembled beam; The clamp is used to clamp the middle and / or upper part of the simply supported beam; the deviation correction device is used to adjust and fix the perpendicularity between the simply supported beam and the cover beam. The invention also provides a construction method of a simple-supported bridge and then a continuous bridge. The riding-hanging support structure and the construction method of the simply-supported and then continuous bridge provided by the invention reduce the bridge construction cost, equipment purchase cost and turnover cost.

Description

technical field [0001] The invention belongs to the technical field of bridge construction, and more specifically relates to a riding-hanging support structure and a simply-supported and then continuous bridge construction method. Background technique [0002] Simply supported beams are simply supported first and then continuously constructed at high piers. If steel pipe columns are used for temporary support, a large number of steel pipes will be used, and the cost will be high. The distance between the pad stone and the edge of the cover beam is short, and the concrete at the end of the cover beam needs to be cast in place as a whole. The structural stability is poor, and the support space available for the beam erection equipment is limited, so the bridge frame beam cannot be used. The horizontal and vertical offset and verticality of the structure can be adjusted by using the three-way jack, but the cost is high, and the three-way jack cannot be removed before the concre...

Problems solved by technology

[0003] The purpose of the embodiments of the present invention is to provide a saddle-mounted support structure and a construction method of simply supported first and then continuous bridges, aiming to solve the existing simple supported first and then continuous bridge construction technology, which needs to build temporary supports and requires high costs. And the horizontal and vertical offset and verticality of the structure can be adjusted by using the three-way jack, which is a technical problem with high cost
