Construction method for long-span overhung specially-shaped limit exceeding structure steel corridor

Abstract

The invention discloses a construction method for a long-span overhung specially-shaped limit exceeding structure steel corridor. The method includes the following steps that firstly, the steel corridor is divided into construction units, wherein the inner part of a corridor structure and middle strip blocks of an upper steel structure of a corridor overhung part are classified as the first construction unit, the remaining part of the corridor overhung part is classified as the second construction unit, and a corridor suspension part is classified as the third construction unit; secondly, a high-altitude bulk assembly method and a cantilever installation method are adopted for finishing construction of the first construction unit on a floor panel of a tower A; thirdly, construction of the second construction unit is finished through integral lifting; and fourthly, construction of the third construction unit is finished through sliding after integral lifting. The high-altitude bulk assembly technology, the integral lifting technology, the sliding after integral lifting technology and the like are applied, work hours are reduced, the material cost and equipment cost are saved, and the requirements for integral control over multiple aspects of the construction process, the quality, the safety, the schedule, the cost and the like are met.

Description

technical field [0001] The invention relates to a construction method for a steel corridor, in particular to a construction method for a steel corridor with a large-span cantilevered special-shaped overrun structure. Background technique [0002] With the development of social economy, people's demands and needs for buildings are also increasing and improving, and a large number of conjoined complex high-rise buildings have emerged. Conjoined structures generally refer to two or several high-rise buildings connected to each other by overhead connectors to meet the requirements of building shape and use function. On the one hand, the setting of the conjoined structure is due to the requirements of architectural functions, which can facilitate the connection between the two towers. The current conjoined structure has good lighting effects and a wide field of vision. Due to the setting of the conjoined structure, the appearance of the building is more distinctive. At present,...

AI Technical Summary

Problems solved by technology

The working surfaces of the above-mentioned components are all carried out on the floor slab of the podium, but the floor slab of the above-mentioned podium does not have the capacity to carry 425 tons

In summary, the construction of the above-mentioned steel structure corridor cannot be completed by using the existing construction method of large-span high-altitude conjoined steel structure
