Abstract
The invention discloses a large-formwork lifting-type construction method for a shear wall or cylinder concrete structure. A formwork system is allowed to replace a traditional plywood by a specialized large formwork. Meanwhile, a poured concrete wall is adopted as a support point, operation platforms are arranged and lifted by a tower crane, so that construction on a shear wall or a cylinder concrete wall is completed. The large-formwork lifting-type construction method is characterized by including mounting the tower crane, producing the large formwork and an upper-portion operation platform, mounting a pre-embedded member, pouring and maintaining concrete, disassembling the large formwork and a supporting system thereof, producing a middle operation platform and a lower-portion operation platform, mounting steel bars on the middle operation platform, moving the cleaned large formwork, mounting the formwork on the middle operation platform at a new position, straightening the device, and pouring concrete on the upper-portion operation platform at a new position. The large-formwork lifting-type construction method has the advantages of convenience and practicality, labor hours are saved, and cost is lowered.
Description
Technical field
The present invention relates to technical field of building construction, relate in particular to shear wall, cylindrical shell concrete structure large form lift-type job practices.
Background technology
Along with building is more and more higher, shear wall and cylindrical shell concrete structure are more and more, and the domestic traditional job practices of shear wall and cylindrical shell concrete is to set up two steel pipe scaffolds that efflux around building, concrete wall adopts veneer formwork, tower crane vertical transport.This job practices exists artificial amount large owing to need to set up two exterior scaffolds, and the tower crane utilization ratio is low, the shortcoming that the veneer waste is serious.
Summary of the invention
Purpose of the present invention is exactly the deficiency that exists for prior art, shear wall, cylindrical shell concrete structure large form lift-type job practices are provided, template system is changed into the large form of customization by traditional veneer, simultaneously, with concreting wall as the strong point, setting operation platform, and promoted by tower crane, thus the construction of shear wall, cylindrical shell concrete wall finished.
The object of the present invention is achieved like this: shear wall, cylindrical shell concrete structure large form lift-type job practices is characterized in that: carry out according to the following steps:
1, arrange the installation tower crane, its radius can cover whole building.
2, making the large form panel with the thick veneer of 18mm, highly is floor height, and width is 6m, makes vertical back cord with 50 * 100mm lumps of wood, and the 8# channel-section steel is made horizontal back cord, reinforces with split bolt.The steel tripod of width 0.9m is set on large form top, lays plank, railing above the steel tripod, be configured for the upper operating platform of concrete construction to be built.
3, built-in fitting is installed, wait build the concrete wall reinforcement installation complete after, in concrete wall to be built, install and be used for the built-in fitting that next step installs middle part operating platform and bottom operating platform.
4, build and curing concrete, reach some strength after, remove large form and support system thereof, and winch to cleaning on the newly placed concrete flooring, trimming with tower crane.Wherein, the panel of large form and support system thereof, vertical back cord, laterally back cord, and the steel tripod in the upper operating platform, plank, railing all promote together.
5, middle part operating platform and the bottom operating platform on the pouring concrete, preparation method is with the top operating platform, namely lay plank, railing at the steel tripod, with tower crane movable lifting middle part and bottom operating platform, with former treat two built-in fittings burying underground in the pouring concrete reinstall respectively fix in the middle part of and the bottom operating platform.
6, the middle part operating platform of constructor on reposition installed reinforcing bar.
7, move the good large form of cleaning and support system thereof to concreting position next time with tower crane.
8, constructor's installation form and machine straightening device on the middle part operating platform on the reposition, concreting on the upper operating platform on the reposition.
According to this circulation is until finish the concrete construction of wall.
Compared with prior art, advantage of the present invention is: not only simple and practical, and save man-hour, and reduce cost.
