Problems solved by technology

This construction method needs to set two rows of supports in the longitudinal bridge direction on the upper part of the middle pier. In order to place the two rows of supports in the longitudinal bridge direction, the size of the top of the middle pier along the longitudinal bridge direction needs to be larger than that of only one row of supports. , the detailed structure is complex
This construction method makes the amount of support and pier materials more than other methods, and the cost is high

Abstract

The invention discloses a steel plate beam connecting structure. The connecting structure comprises two connecting parts which match each other, the two connecting parts are located on two different steel plate beams, each connecting part comprises a step arranged at the end of the corresponding steel plate beam and connecting plates fixedly arranged on the two sides of the step, the connecting plates in the two connecting parts are in one-to-one correspondence, and the two corresponding connecting plates are fixedly connected through bolts. The connecting structure of the steel plate beam issimple in structure and convenient to connect, the construction procedure of the steel plate beam can be greatly simplified, and the construction cost is reduced.

Description

technical field [0001] The invention relates to the technical field of bridges, in particular to a connection structure of steel plate girders. Background technique [0002] The steel plate girder in the steel plate composite bridge is a steel structural member welded by upper flange steel plate, steel web and lower flange steel plate. For the multi-span continuous steel plate composite girder bridge, its construction method is generally to erect the steel girder first, and then construct the concrete bridge deck. Among them, there are many construction methods for steel beams, such as support method construction, jacking method construction and so on. The construction of steel plate girders using the bracket method is the most common construction method. The specific construction method is: steel plate girders are usually processed into multiple sections in the factory, transported to the construction site for splicing to form a large-segment beam body, and then use a car ...
