High-altitude large cantilever concrete structure steel support platform

Abstract

The invention relates to a high-altitude large-cantilever concrete structure structural steel supporting platform. The high-altitude large-cantilever concrete structure structural steel supporting platform comprises a multi-truss structural steel triangular supporting bracket, a box iron horizontal connecting beam and a plurality of box iron horizontal purlines. The multi-truss structural steel triangular supporting bracket comprises a main beam, a horizontal rod, a vertical rod, a first inclined supporting rod and a second inclined supporting rod. The main beam is installed on a boundary beam of a frame structure on the next layer of a cantilever structure needing to be constructed, the first inclined supporting rod and the second inclined supporting rod are installed on a boundary beam of a frame structure on the next second layer and a boundary beam of a frame structure on the next third layer of the cantilever structure needing to be constructed respectively, the horizontal rod is connected with the first inclined supporting rod and the second inclined supporting rod, the joint of the second inclined supporting rod and the horizontal rod is connected with one end of the vertical rod, the other end of the vertical rod is connected with the main beam, the box iron horizontal purlines are welded to the upper surface of the main beam in a laying mode and are used for erecting a formwork support and an external scaffold, and multi-truss structural steel triangular supporting brackets are connected through box iron horizontal connecting beams in a welding mode. The high-altitude large-cantilever concrete structure structural steel supporting platform solves the problem that the construction difficulty of an ultrahigh and large-cantilever structure with large component loads is high.

Description

technical field [0001] The invention relates to the field of building technology, in particular to a high-altitude large-cantilever concrete structure steel support platform. Background technique [0002] In order to meet the needs of highlighting the effect of building facade modeling and the expansion of high-rise upper space in architectural design, there have been more and more buildings with high-rise cantilevered concrete structures and components in recent years. The self-weight and wind load of the high-altitude cantilever structure are relatively large, and the stability and rigidity of the formwork support system during construction are required to be high, and the high-altitude operation requires the construction process of the entire support system to be absolutely reliable and safe. The choice of support form and material is very important. For example, the headquarters of Shanghai Yuantong Express Co., Ltd. is located in the west of Huaxu Highway and north of ...

AI Technical Summary

Problems solved by technology

For a cantilever structure over 2m, due to the large structural load, the required cantilever steel section is also large, resulting in a large self-weight, the design of the cantilever structure needs to be reviewed, and a large design adjustment is required. Cross-sectional changes will affect the function of use
