Drum frame supporting power built-in integrated jacking steel platform formwork system and construction method

Abstract

The invention discloses a drum frame supporting power built-in integrated jacking steel platform formwork system, comprising a steel platform, a support system, a suspended scaffold, a template system and a hydraulic jacking power system; the support system comprises a drum frame support and an internal framework support; the drum frame support is located under the steel platform, and comprises a steel platform support, an oil cylinder counter-force beam, a guide roller, a support steel column and a drum frame support beam; the internal framework support is arranged inside the drum frame support and located between the drum frame support beam and the oil cylinder counter-force beam; the hydraulic jacking power system comprises a hydraulic jacking oil cylinder and a power control system thereof; the hydraulic jacking oil cylinder is inverted between the oil cylinder counter-force beam and the internal framework support; telescopic brackets are arranged at the end portions of the internal framework support and the drum frame support beam, respectively; and the telescopic brackets are supported in a preformed hole in a shear wall. The drum frame supporting power built-in integrated jacking steel platform formwork system is capable of realizing the construction operation of a complex core drum, shortening the construction period and ensuring high altitude construction safety, and also capable of improving the green construction level.

Description

Technical field [0001] The invention belongs to the technical field of building construction, and relates to a construction equipment and a construction method for high-rise or super high-rise buildings, and in particular to a cylindrical support type power built-in integral jacking steel platform formwork for construction of reinforced concrete structures System and construction method. Background technique [0002] At present, there are many methods and devices for steel platform technology in the construction of high-rise or super high-rise buildings at home and abroad, but these existing technical construction methods and devices have some shortcomings. Chinese patent CN201381634Y discloses a low-position three-fulcrum long-travel jacking steel platform variable formwork system, which has high requirements on the core tube structure plane. When the core tube structure is complex, the steel platform formwork system is difficult to arrange, and because of its lifting The step ...

Problems solved by technology

Chinese patent CN201381634Y discloses a low-position three-point long-stroke jacking steel platform variable formwork system, which has high requirements for the plane of the core tube structure. When the core tube structure is complex, it is difficult to arrange the steel platform formwork system. The step distance is 1 storey high, the cylinder body and piston rod are too long, and the adaptability to variable storey height and super high floor structure is insufficient, the maximum stroke of the hydraulic cylinder is greater than the height of a process floor, and the steel platform adopts a steel truss structure , it is difficult to implement the split and deformation of the steel platform

Chinese patent CN10194921A discloses a low-position, less-fulcrum modular integral jacking steel platform formwork system, which only introduces its module design, but does not involve the construction method of the steel platform formwork system, especially lacking pertinence in high-altitude and complex construction conditions In addition, the jacking step introduced by it is 1 storey high, the cylinder body and piston rod are too long, and the adaptability to the floor structure with variable storey height is insufficient. The lower beam (steel platform lifting support beam) and the upper beam (steel platform) The distance between the platform bottom beams) is too large, the closure of the steel platform system is very difficult, and there are safety hazards in the construction of high-altitude complex environments. The steel corbels are located in the upper and lower support beams, so that the steel corbels are in place, adjusted and shelved. Insufficient flexibility; Chinese patent CN1104704A discloses a self-elevating integral steel platform with an inner cylinder and an outer frame, but its support system is a buried steel column, which needs to be deformed and disassembled when the steel platform system needs to be deformed and disassembled in the construction of complex super high-rise buildings. Temporary relay stress conversion complicates the construction conditions, relatively weak adaptability, and also affects the safety of high-altitude construction
