Problems solved by technology

However, due to the large width of the ultra-wide steel box girder components (which can exceed 5m), during transportation, if the width of the sluice along the line or the distance between the bridge piers along the line is small, the large steel box girder components will be ultra-wide and difficult to transport; even Disassemble the ultra-wide components into multiple units for transportation, and it is inconvenient to accurately splice and position on the ship

Abstract

The invention relates to the field of methods or equipment special for erecting or assembling bridges, in particular to an overwater splicing locating device of an ultra-wide steel box beam componentused for a bridge and a use method of the overwater splicing locating device. The overwater splicing locating device of the ultra-wide steel box beam component used for the bridge comprises a steel box beam body (11) and side wing units (12) and is characterized in that the overwater splicing locating device further comprises main clamp plates (21), main fixed plates (22), auxiliary clamp plates (23), auxiliary fixed plates (24), bolt-nut assemblies (3), adjustable supporting rod assemblies (4) and lifting lugs (5), and the auxiliary clamp plates (23) and the main clamp plates (21) are connected and fixed; and the auxiliary fixed plates (24) and the main fixed plates (22) are connected. The use method of the overwater splicing locating device used for the bridge is characterized by being sequentially implemented according to the following steps of a, shipping, b, splicing, and c, detachment. The overwater splicing locating device is simple in structure, convenient to construct, high inenvironmental adaptability, high in operation efficiency and capable of saving cost.

Description

technical field [0001] The invention relates to the field of methods or equipment specially used for erecting or assembling bridges, in particular to an above-water splicing and positioning device for super-wide steel box girder components used in bridges and a method for using the same. Background technique [0002] Steel is light in weight and high in strength, and steel structure bridges have greater spanning capacity than concrete bridges, and the steel structure processing speed is fast, so steel structures are widely used in long-span bridge structures. However, due to the large width of the ultra-wide steel box girder components (which can exceed 5m), during transportation, if the width of the sluice along the line or the distance between the bridge piers along the line is small, the large steel box girder components will be ultra-wide and difficult to transport; even Dismantling the ultra-wide components into multiple units for transportation is also inconvenient for...
