Problems solved by technology

[0006] The disadvantages of the first construction method above are: the overall high-altitude hoisting of the rotating hyperboloid network frame requires particularly high hoisting equipment, high safety risks, high cost, and difficult high-altitude operations
[0007] The disadvantages of the second construction method are: not only high-altitude assembly, large welding workload, on-site mechanical equipment is difficult to meet the hoisting requirements, but also the required high-altitude tire assembly frame is difficult to build, there are great safety and quality risks
The difficulty of construction is not conducive to the safety, quality and control of the construction period of the steel structure on-site installation

Embodiment Construction

[0022] In the following, the present invention will be further explained by taking the steel structure project of the secondary reflection tower of the 50 thousand kilowatt solar thermal power generation module of the molten salt tower in a certain place as an example.

[0023] 1. Engineering requirements:

[0024] Such as figure 1 As shown, the designed steel structure of the reflecting tower is composed of a secondary reflecting structure 1 at the top and three groups of lattice columns 2 at the bottom. A waist truss 3 and a supporting truss 4 between the three groups of lattice columns 2 are also required.

[0025] Among them, the secondary reflection structure is the above-mentioned steel member of the present invention, which is composed of a square pyramid grid frame and a mirror secondary structure. The main structure of the secondary reflection tower is a steel structure, and the upper structure is a rotating hyperboloid grid supported by three lattice columns. The maximum ra...

Abstract

The invention discloses a construction technology of a large high-altitude assembled steel member and relates to the technical field of construction of large assembled steel members. A temporary fullbracket is erected on the ground, and an upper main structure of the large assembled steel member is assembled; a plurality of sets of temporary lifting towers are mounted and fixed to a reinforced concrete foundation of a vertical steel support through pre-embedded iron parts, and lifters are fixed to all sets of lifting brackets in a distributed mode; and the steel support is built in a sectioned mode. Through sectioned accumulation lifting of the steel support, the upper steel member is lifted, and the large steel member with the extremely large weight is lifted without other heavy liftingdevices. The mounting and construction difficulty is greatly lowered, and the construction technology has great advantages of controlling over the quality, safety, construction period and constructioncost and the like.

Description

Technical field [0001] The invention relates to the technical field of construction of large-scale assembled steel components, in particular to the construction technology of large-scale assembled steel components built at a high altitude from the ground. Background technique [0002] Certain large-scale assembled steel components need to be supported high in the sky by steel supports (lattice columns), and the large-scale assembled steel components are assembled from multiple pieces of steel materials, and their own weight is extremely heavy and bulky. [0003] In the past, there were two construction methods for the above-mentioned large assembled steel components: [0004] A method of assembling steel materials outside the pre-installation site, and at the same time, performing support (lattice column) construction on the pre-installation site. After both have been formed, the assembled steel materials will be assembled with a large spreader Hang to the top of the steel support (...
