Construction method for large-span overhung ultra-limit structure

Abstract

The invention discloses a construction method for a large-span overhung ultra-limit structure. The method includes the following steps that 1, construction unit classification is carried out on the ultra-limit structure, wherein the internal part of the structure and a middle strip block of an upper steel structure of the overhung part of the structure are classified as a first construction unit, and the rest part of the overhung part is classified as a second construction unit; 2, construction of the first construction unit is completed on a tower floorboard through a high-altitude assembly method and a cantilever installation method; 3, construction of the second construction unit is completed through integral lifting and slipping after integral lifting. According to the method, the multiple technologies of high-altitude assembly, integral lifting, slipping after integral lifting and the like are adopted, labor time is shortened, material expense and equipment expense are reduced, and the requirement for integral control over the construction technology, quality, safety, progress, cost and the like is met.

Description

technical field [0001] The invention relates to a construction method for an overrun structure, in particular to a construction method for a large-span overhang 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, the construction methods of large-sp...

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

To sum up, the left part connected to Tower A belongs to the large-span cantilever overrun structure, and the construction of the above-mentioned long-span overhang overrun structure cannot be completed by using the existing construction method of long-span high-altitude conjoined steel structure
