Embodiment 1

[0027] The invention discloses a large formwork lifting construction method for shear walls and cylindrical concrete structures (such as figure 1 shown), including the following steps:

[0028] 1) arrange and install tower crane;

[0029] 2) Use plywood to make a large formwork panel 1 whose height is the height of the storey, use square wood as the vertical back corrugation 2, and 8# channel steel as the horizontal back corrugation 3, and reinforce it with pull bolts 4;

[0030] 3) After the steel bars of the concrete wall to be poured are installed, install the embedded part 5 for the next wall in the concrete wall to be poured, and remove the large formwork and the panels of its support system, the vertical back corrugation, and the horizontal back corrugation;

[0031] 4) Pour and maintain the concrete. After reaching a certain strength, push the movable tripod platform 6 upward into the embedded parts of the poured wall, and use the embedded parts to fix the movable tria...

Embodiment 2

[0033] Embodiment 2: The present invention also discloses a movable triangular platform (such as figure 2 , image 3 shown), the movable triangular platform includes a supporting steel plate 7, a supporting base plate 8, a reinforcing inclined bar 9 and a vertical pole 10, a roller 11 is installed on one end of the supporting steel plate, and a guardrail is installed on the other end of the supporting steel plate 12. One end of the supporting base plate is equipped with a roller, one end of the reinforcing slanting rod is fixedly connected to one end of the supporting steel plate with a guardrail, and the other end of the reinforcing slanting rod is fixedly connected to the end of the supporting base plate away from the roller; one end of the vertical support rod is fixed Connect one end of the supporting base plate away from the roller, and the other end is fixedly connected to the side of the supporting steel plate near the roller. The concrete wall is installed with the w...

Abstract

The invention discloses a large-formwork lifting-type construction method of a shear wall and a cylinder concrete structure. The large-formwork lifting-type construction method comprises the followingsteps that (1) a tower crane is arranged and mounted; (2) a large-formwork face plate is manufactured through veneers, vertical back arris are manufactured through square timbers, transverse back arris are manufactured through 8# channel steel, and reinforcing is conducted through split bolts; (3) an embedded part used for a next layer of wall surface is mounted in the to-be-poured concrete wall,and a large formwork as well as the face plate, the vertical back arris and the transverse back arris of a supporting system of the large formwork are dismantled; (4) concrete pouring and curing areconducted, a movable tripod platform is upwards pushed into the embedded part of the poured wall surface and fixed, the large formwork as well as the face plate, the vertical back arris and the transverse back arris of the supporting system of the large formwork are mounted on a next to-be-poured upper layer concrete wall layer surface, steel bars of a next more upper layer wall surface are mounted, and the concrete wall surface is poured; and (5) circulating is conducted on the basis till construction of wall concrete is completed. The movable tripod platform is adopted for integral-type moving, the tripod platform does not need to be repeatedly set up, and manpower is greatly saved accordingly.

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 shear walls and cylindrical concrete structures, so that the existing construction of shear walls and cylindrical concrete structures...
