Construction method and equipment of ultra-long suspenders in parallel

Abstract

The invention mainly discloses a method and equipment for sequentially constructing ultra-long hanging posts in a high-rise structure. The method includes steps of firstly, mounting a bottom uninstalling device of the hanging posts, filling high-strength steel sand in the uninstalling device and screwing down temporary connecting rods; secondly, mounting the hanging posts and steel frame beams adjacent to the hanging posts until a hanging post top structure is completely constructed; thirdly, synchronously unscrewing pressure release valves on the periphery of the uninstalling device to uninstalling the hanging posts; fourthly, cleaning residual steal sand in the uninstalling machine after the hanging posts are completely uninstalled, removing the temporary connecting rods, cutting off temporary connecting annular plates, sealing gaps between a bottom piston of the hanging posts and the uninstalling device and performing anti-corrosion treatment on the gaps between the bottom piston of the hanging posts and the uninstalling device so as to completely constructing the hanging posts. The equipment comprises the uninstalling device, the pressure release valves, the two temporary connecting annular plates, the multiple temporary connecting rods, the bottom piston of the hanging posts and the high-strength steel sand. The method and the equipment have the advantages that construction temporary measures can be reduced, the installation efficiency can be improved, the construction period can be shortened, the hanging posts can be conveniently and quickly uninstalled, and efficient and high-quality uninstalling work can be implemented.

Description

technical field [0001] The invention relates to the technical field of construction of steel structure suspenders, in particular to a sequential construction method and equipment for super-long suspenders in high-rise structures. Background technique [0002] With the development of modern building structures, the building space structure is becoming more and more complex. In order to meet the requirements of architects for large space and long span, steel structure hanging columns have been widely used. At the same time, because the steel structure davit is only subjected to tension, it can give full play to the mechanical properties of steel, so the davit structure is also favored by structural engineers. [0003] Although the steel structure davit has many advantages, it has caused many difficulties in construction due to its unique force-bearing form. In particular, there is no relatively mature construction method in China for the construction of super-long suspenders ...

AI Technical Summary

Problems solved by technology

[0005] (1) If the reverse post-installation method is used for installation, since the super-long suspender spans several floors, post-installation in sections and layers is required. This construction method not only requires a large number of temporary support measures, but also has low installation efficiency and affects installation progress;

[0006] (2) If the temporary support method is adopted for installation along the way, the risk factor of temporary support erection and dismantling at high altitudes will be greatly increased, and at the same time, the unloading of the davit will become a difficult project
