Construction method of high-altitude double-layer super-long cantilever reinforced concrete structure

Abstract

The invention discloses a construction method of a high-altitude double-layer super-long cantilever reinforced concrete structure, belongs to the field of building construction, and aims to solve thetechnical problems about how to perfect high-altitude large cantilever structure construction, effectively control the internal stress change of concrete and profile steel deformation while the construction period is saved, and prevent cantilever section concrete from cracking due to stress. According to the adopted technical scheme, a method specifically comprises the following steps that S1, cantilever section steel is adopted in a cantilever beam to serve as foundations for supporting scaffolds, the cantilever section steel is fixed through steel bar pull rings pre-buried in floor slabs, and the steel pipe fastener type all-round scaffolds are erected at the upper portions of the cantilever section steel; S2, in combination with different cantilever lengths, the bending moment of the section steel at the lower part of the cantilever beam is checked, and calculation that a cantilever section steel beam support meets the length range of the cantilever beam is carried out; S3, horizontal connecting rod pieces are installed between the cantilever section steel; and S4, a lever method principle is applied to construction of the double-layer cantilever reinforced concrete structure, and construction is conducted from inside to outside when a full supporting frame is erected.

Description

Technical field [0001] The invention relates to the field of building construction, in particular to a construction method of a high-altitude double-layer super-long cantilevered reinforced concrete structure. Background technique [0002] Scaffold refers to various supports erected on construction site for workers to operate and solve vertical and horizontal transportation. A general term in the construction industry, refers to the construction site used for exterior walls, interior decoration, or places with high floors that cannot be directly constructed. Mainly for construction personnel to work up and down or to protect the outer safety net and high-altitude installation of components. To put it bluntly, it is to set up scaffolding. Scaffolding materials usually include bamboo, wood, steel pipe or synthetic materials. Some projects also use scaffolding as templates, and are also widely used in the advertising industry, municipal administration, traffic roads and bridges, mi...
