AI Technical Summary
In the lifting of large-span steel pipe trusses, the height adjustment efficiency of the tower crane standard section is low and costly. Especially when the elevation does not meet the multiple of three meters, the tower crane standard section needs to be cut and welded, resulting in high construction difficulty and increased cost.
A temporary support tire frame including a tower crane standard section support frame and a top adjustment frame is designed. The top adjustment frame consists of vertical support columns, adapter plates, adjustment rods, guide columns and support frames, which are realized by connecting the adjustment rods and threads. Height adjustment avoids the need for cutting tower crane standard section.
It realizes the free adjustment of the support height without cutting the standard section of the tower crane, which reduces construction costs and construction periods, speeds up construction efficiency, and improves construction stability and safety.

More and more roofs use spatial steel truss structures. For large-span steel trusses, segmented lifting is adopted. Temporary support frames mostly use tower crane standard sections as temporary support cradles. Compared with full-floor scaffolding, tower crane standard sections have the advantages of turnover, fast construction efficiency, and stable structure. However, since the height of the tower crane standard sections is a multiple of three meters, for spatial steel pipe trusses with different elevations or elevations that do not meet the multiple of three meters, it is necessary to cut the tower crane standard section and then weld I-beams to the tower crane standard section to adjust the cradle height. Cutting the tower crane standard section will increase costs. One temporary support frame needs to destroy a tower crane standard section, and cutting the tower crane standard section is inefficient and difficult to construct. Utility Model Content
