Super high-rise post-cast floor steel bar reserved formwork and construction method thereof

Abstract

The invention discloses a super high-rise post-cast floor steel bar reserved template, which is very stable and firm in fixation of reserved steel bars, ensures that the reserved steel bars have very good stability in the subsequent pouring construction, and ensures the pouring construction quality and the overall construction economic benefit, and through a construction method of the super high-rise post-cast floor steel bar reserved template, the construction efficiency is improved, and the construction cost is reduced. A core tube shear wall formwork is innovated and transformed, double grooves of a post-pouring floor slab reserved steel bar are additionally formed in the upper side of the formwork, and an L-shaped steel bar is reserved on the outer side of a core tube shear wall structure, so that steel bar planting-free and chiseling-free construction of the post-pouring floor slab reserved steel bar is achieved, the forming quality of the reserved steel bar is effectively guaranteed, the reserved steel bar is accurately positioned, and the construction efficiency is improved. The influence of chiseling on the overall stress of the structure is reduced, the construction cost is reduced, and the construction efficiency is improved; the device can be repeatedly used, and benefits are remarkable.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a super-high-rise post-poured floor reinforcement reserved formwork and a construction method thereof. Background technique [0002] In recent years, with the growth of the economy and the advancement of construction technology, urban super high-rise buildings with limited construction land have sprung up like mushrooms; at present, most of the super high-rise buildings under construction are in the form of core tube shear wall-outer frame The steel concrete frame structure is subject to the sequence of the vertical cross-operation of the internal and external structures of the core tube. The internal and external floors of the tube usually lag behind the core tube shear wall structure by more than 8 floors, so as to ensure the orderly progress of the construction work; therefore, in the core tube During the construction of the tube shear wall, the steel bars used t...

Problems solved by technology

[0003] The above-mentioned method 1 has a huge amount of work and high additional investment; method 2 and method 3 reserved steel bars will be easily bonded together due to factors such as the inability of the steel bars to be fixed firmly during construction and the vibration deviation during concrete pouring. The spacing in the horizontal direction is uneven, and the spacing of the gluten and bottom bars in the vertical direction does not meet the design requirements, so that many of the reserved steel bars cannot be used, and the follow-up still needs to be planted. The deep groove formed by the chisel will affect the overall stress of the structure, and during the pouring construction process, the position of the steel bar may be shifted. The common method is to use iron wire binding, which is too complicated to operate and affects the construction efficiency. Inconvenient, and has an impact on its overall pouring strength, resulting in overall stability that cannot meet actual construction needs
