Description

Technical Field

[0001] This utility model relates to the field of eccentric steel arch corridor support positioning technology, specifically a precise positioning device for large-span spatial eccentric steel arch corridor support. Background Technology

[0002] With the acceleration of urbanization and the continuous advancement of building technology, large-span spatial structures are being used more and more widely in the field of architecture. These structures, such as stadiums, exhibition halls, and airport terminals, not only require a grand appearance and spacious interior, but also need to meet the requirements of high precision, high safety, and high durability. As a special type of large-span spatial structure, the design and construction of the supporting structure of eccentric steel arch corridors are particularly complex. Eccentric supports have energy-dissipating beam segments between the supporting diagonal rods and the beam-column joints, which have good plastic deformation capabilities. However, during construction, it is necessary to ensure the precise positioning of the supporting structure.

[0003] In existing technologies, positioning devices for large-span spatial torsion steel arch corridors suffer from low positioning efficiency and insufficient accuracy. For example, traditional positioning devices use an integral support structure, which requires repeated adjustments to the component positions during installation, resulting in a long construction period. Furthermore, it is difficult to adapt to the precise positioning requirements of complex spatial torsion components. Consequently, in actual use, this support structure cannot quickly adapt to steel arches with different spatial torsion angles. At the same time, the integral installation leads to poor adjustment flexibility and significant error accumulation. Therefore, it is necessary to improve the precise positioning device for the support of large-span spatial eccentric steel arch corridors. Utility Model Content

[0014] Compared with the prior art, this utility model provides a precise positioning device for supporting large-span spatial eccentric steel arch corridors, which has the following beneficial effects:

The dimensions of each individual part are customized according to the spatial torsion angle of the steel arch components. The intersecting line interfaces are processed by the engineering team. After customization, they are fixed and welded to form a box structure.

Then, the connection effect between the device and the connection point is improved by bolts or concrete pouring, thereby preventing the device from moving during the positioning process.
