Problems solved by technology

[0003] At present, most of the steel-concrete composite beams in China are in the form of the more common single-box steel-concrete composite beams. There is no horizontal connection between boxes. Higher requirements are put forward for the manufacturing accuracy of the beam factory. If the processing accuracy of the steel box girder does not meet the construction requirements, it will inevitably affect the connection quality of the steel box segment assembly and the bolted connection of the beams between the boxes, and the overall construction quality and engineering quality of the steel-concrete composite beam. progress is difficult to guarantee

Embodiment Construction

[0024] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0025] As mentioned in the background technology, most of the steel-concrete composite beams in China are relatively common single-box steel-concrete composite beams, and there is no transverse connection between boxes. When transported to the on-site assembly, very high manufacturing requirements are often placed on the precision of the steel box girder produced in the steel box girder factory. If the processing accuracy of the steel box girder does not meet the construction requirements, it will inevitably af...

Abstract

The invention discloses an in-plant steel box girder segment continuous matching construction method. The method comprises the steps of: assembling and splicing steel box girder segments; carrying outlongitudinal matching on the assembled and spliced steel box girder segments; and conducting transverse continuous matching on the steel box girder obtained after longitudinal matching. The continuous matching construction method is applied to in-plant processing and manufacturing of steel beams. By means of the method, the steel beam machining precision can be effectively improved, the steel boxsegment on-site assembly and steel-concrete composite beam installation work efficiency is improved, the connection quality between steel box segments and between boxes is guaranteed, the high-altitude adjustment risk is avoided, the positioning installation precision of the steel-concrete beams and the overall beam erecting efficiency are further improved, and the man-machine cost is reduced.

Description

technical field [0001] The invention relates to the field of bridge engineering, in particular to a continuous matching construction method of steel box girder segments in a factory. Background technique [0002] In recent years, steel-concrete composite beams, as a new technology and new technology, have been more and more widely used in urban overpass bridges in my country, and are developing in the direction of large spans. [0003] At present, most of the steel-concrete composite beams in China are in the form of the more common single-box steel-concrete composite beams. There is no horizontal connection between boxes. Higher requirements are put forward for the manufacturing accuracy of the beam factory. If the processing accuracy of the steel box girder does not meet the construction requirements, it will inevitably affect the connection quality of the steel box segment assembly and the bolted connection of the beams between the boxes, and the overall construction qual...
