Abstract

The invention discloses a lifting construction method and a construction device of a large formwork for a shear wall tubular concrete structure. The lifting construction method comprises the followingsteps of, (1) arranging and installing a tower crane; (2) making a large formwork panel with plywood, manufacturing a vertical backstay with square wood, manufacturing a horizontal backstay with 8 #channel steel, and using pull bolts to reinforce; (3) installing embedded parts for the wall surface of the next layer in the concrete wall to be poured, removing the large formwork and the panel, thevertical backstay and the horizontal backstay of a support system thereof; (4) pouring and curing concrete, pushing a movable tripod platform upwards into the embedded parts of the poured wall surface, and fixing the movable tripod platform; installing the large formwork and the panel, the vertical backstay and the horizontal backstay of the support system on the next upper concrete wall surfaceto be poured, and installing reinforcing steel bars of the next upper layer wall surface and pouring the concrete wall surface; and (5) repeating the cycle, until the construction of wall concrete iscompleted. The method adopts a movable tripod platform to move integrally, and greatly saves manpower.

Description

technical field [0001] The invention relates to the field of building engineering construction, in particular to a construction method of a large formwork lifting type for a shear wall and a cylindrical concrete structure. Background technique [0002] As buildings get taller, there are more and more shear walls and cylindrical concrete structures. The traditional domestic construction method of shear walls and cylindrical concrete is to erect double outer rows of steel pipe scaffolding around the building, and the concrete walls The plywood formwork is used, and the tower crane is transported vertically. This construction method has the disadvantage of a large amount of labor due to the need to set up double outer rows of scaffolding. Contents of the invention [0003] The invention provides a large formwork lifting construction method for a shear wall cylindrical concrete structure, which is used to solve the defect that the existing construction of the shear wall cylin...
