AI Technical Summary

Technical Problem

In the current construction of dome steel structures, the alignment accuracy between frame units relies on manual calibration, resulting in low construction efficiency and easy misalignment of bolt holes, which affects the construction progress, especially in cases with complex curved surfaces or large spans.

Method used

A dome-shaped steel structure support frame was designed, including an insertion mechanism and a receiving mechanism. The guide block above the insertion mechanism and the guide groove below the receiving mechanism are guided by an inverted Y-shaped structure to help correct the horizontal offset between the frames. The conical structure of the insertion block and the guide block reduces the insertion resistance and enables quick alignment of the bolt holes. The limiting unit ensures a stable connection through mechanical locking.

Benefits of technology

It significantly improves the positioning efficiency and connection accuracy of frame installation, reduces the frequency of manual adjustments, shortens construction time, and improves the stability of connections and the convenience of reuse.

Abstract

The utility model discloses a dome steel structure supporting jig frame, relates to the technical field of jig frames, and aims to solve the technical problems that manual alignment efficiency is low and bolt holes are prone to dislocation when frame bodies are stacked and installed, the dome steel structure supporting jig frame comprises a frame body, an inserting mechanism and a receiving mechanism, the inserting mechanism is arranged above the frame body, and the receiving mechanism is arranged below the frame body. And the receiving mechanism is arranged right below the insertion mechanism. The guide blocks and the inverted-Y-shaped guide grooves are matched in a guiding mode, the stacking and positioning process of the frame bodies is optimized, when the second frame body is arranged above the first frame body, in the process that the insertion blocks are embedded into the insertion grooves, the guide blocks distributed on the circumference of the insertion blocks are guided by the inclined faces to slide to the center positions in the grooves, horizontal deviation between the frame bodies is automatically corrected, and the stability of the frame bodies is improved. The Y-shaped structure can absorb initial alignment deviation, bolt holes of the upper fixing plate and the lower fixing plate are rapidly aligned, manual repeated calibration operation is reduced, the fixing plates are tightly attached after connection, an operator can directly fasten bolts, and the construction period is shortened.
