Large-volume anti-deformation steel cage and its binding method

Abstract

The invention relates to a large-volume anti-deformation steel reinforcement cage and a binding method thereof. The binding method comprises the following steps: binding the lower half steel-bar layer of a base-plate steel reinforcement cage to a base-plate binding pedestal; installing a base-plate stiff skeleton on the lower half steel-bar layer of the base-plate steel reinforcement cage; binding the upper half steel-bar layer of the base-plate steel reinforcement cage to the base-plate stiff skeleton; sending the base-plate steel reinforcement cage to a side-wall binding pedestal; binding the half-side steel-bar vertical layer of a side-wall steel reinforcement cage to the side-wall binding pedestal; installing a side-wall stiff skeleton to the bound half-side steel-bar vertical layer; binding another half-side steel-bar vertical layer of the side-wall steel reinforcement cage to the side-wall stiff skeleton; sending the base-plate steel reinforcement cage and the side-wall steel reinforcement cage to a top-plate binding pedestal together; binding the lower half steel-bar layer of a top-plate steel reinforcement cage to the top-plate binding pedestal; installing a top-plate stiff skeleton on the lower half steel-bar layer of the top-plate steel reinforcement cage; and binding the upper half steel-bar layer of the base-plate steel reinforcement cage to the top-plate stiff skeleton, so as to form the top-plate steel reinforcement cage.

Description

technical field [0001] The invention relates to a large-volume anti-deformation reinforcement cage and a binding method thereof, in particular to a method of separately installing a bottom-slab stiff skeleton and a side-wall stiff skeleton during the binding process of the bottom-slab reinforcement cage, the side-wall reinforcement cage, and the top-slab reinforcement cage. A large-volume anti-deformation reinforcement cage and a binding method thereof for realizing stage-by-stage binding of the anti-deformation reinforcement cage and the roof stiff frame. Background technique [0002] At present, large-scale reinforced concrete members that are common in China rarely use large-scale skeletons as members supported by steel cages, and most of them only add reinforcing ribs locally to ensure that the steel cages do not deform. With the development of immersed tube prefabrication construction technology, for super-large subsea tunnel steel cage prefabrication project, the tradi...

Problems solved by technology

With the development of immersed tube prefabrication construction technology, for super-large subsea tunnel steel cage prefabrication project, the traditional reinforcement method has been difficult to meet the design and construction requirements

The main reasons are: (1) The structural size and weight of the steel cage are large, and the deformation caused by its own weight is relatively large; (2) The steel cage is bound in three sections of flowing water; The bottom plate reinforcement is pushed into the wall binding area to bind the wall reinforcement, and then pushed into the roof reinforcement binding area to bind the roof reinforcement, and finally pushed into the pouring area for concrete pouring; it is necessary to ensure that the reinforcement cage is basically maintained during the moving process. No deformation; but the current steel cage binding process can not achieve the above two points
