Description

Technical Field

[0001] The utility model relates to the field of mechanical processing, in particular to a spatial positioning tooling device for a decorative arch of a bridge steel structure. Background Art

[0002] Bridge steel structure is a kind of heavy steel structure in my country. It refers to the main load-bearing and force-bearing parts of the upper part of the bridge made of steel. It is widely used in the construction of bridges for large-scale transportation projects such as municipal construction, water bridges, highways, high-speed railways, and cross-sea bridges. Steel structure has the advantages of light weight, high strength, strong tensile and compressive properties, so it is widely used in bridge construction in my country. The overall performance of steel structure bridges is closely related to their overall design.

[0003] In the Butterfly Bridge project of a cultural park construction project, when the blocks between the segments of the upper structure of the Butterfly Bridge were pre-assembled and installed at the construction site, combined with the characteristics of the bridge steel structure decoration structure and the actual situation on site, during the installation process, a cradle needed to be set up between the segments. The operation was difficult and the spatial position was difficult to ensure, resulting in serious delays in the construction period, long time consumption, high labor costs and poor installation quality.

[0004] On May 9, 2024, a search was conducted in the Chinese Patent Publication Database with "bridge and positioning and bolts and plates and assembly" as the abstract keywords, and several documents were found, namely: CN108570925A-Separated intelligent spherical force measuring support system device and assembly method; CN108202205A-A method for processing refined bolt holes in steel structures in a bridge anchoring system; CN201678943U-Keyed comb-tooth expansion joint device; CN219410983U-A bridge pile foundation protection device; CN213328673U-A bridge guardrail base shaping combined template; CN203514190 U-Bridge expansion device positioning tool; CN103526694A-Bridge expansion device positioning tool; CN205474857U-A bridge chord assembly frame; CN101073839A-Cable-stayed bridge ear plate pin hinge connection structure manufacturing method; CN219862387U-A bridge square column plain concrete pouring template; CN22359504U-Movable and detachable support device for assembling the outward-inclined beam section of the steel structure bridge web; CN206038008U-A bridge span measurement positioning frame; CN215657597U-A frame for improving the assembly accuracy of the prefabricated pier column steel cage; CN217028381 U-A kind of assembled maintenance equipment for road and bridge engineering; CN204199180U-A kind of integral embedded mold for bridge support bolts; CN113481887A-A kind of reinforcement structure based on applying prestress to the bridge deck of highway bridge; CN105290724A-A kind of bridge lower chord manufacturing process; CN204112328U-A kind of steel casing positioning guide frame in the sea; CN208563106U-A kind of railway bridge walking board installation structure; CN114164759A-A kind of bridge anchor structure manufacturing method; CN214831916U-A kind of anti-collision guardrail for road and bridge that is easy to assemble; CN216405148U-A kind of bridge maintenance workbench that is easy to disassemble and assemble; CN219532073U-A kind of bridge survey Measurement equipment; CN204940126U-bridge pad stone anchor hole position controller; CN218405475U-a bridge pile foundation construction casing; CN215949143U-a noise reduction protection fence for highway bridge engineering; CN217053028U-a split-frame bridge safety protection device; CN217203605U-a split upper bearing plate suitable for bridge bearings; CN214170142U-a removable safety guardrail for green construction of bridges; CN213531379U-a cantilever tooling membrane frame; CN216615464U-adjustable transfer attachment frame; CN103510636A-assembled twin viscous energy dissipation device; CN213296085U-a Bailey bridge installation auxiliary tool;CN219061161 U-A safety protection device for construction; CN214005363U-Assembled steel-concrete composite beam bridge; CN215281912U-A prefabricated steel bar rack for bridge construction. ;

[0005] After reading the above documents, it is found that none of them can solve the defects of the prior art: 1. There are too many components to be assembled on site, and it takes a lot of time just to align them on site; 2. It is impossible to quickly achieve alignment of a stable structure.
