Lifting system for construction

Abstract

The invention relates to a template hoisting system for a building. The template hoisting system provided by the invention comprises a top layer platform, a middle layer platform and a bottom layer platform which are sequentially arranged from top to bottom and are mutually parallel, wherein a wall template capable of horizontally sliding along the top layer platform is hung at the bottom of the top layer platform; a tubular upright post perpendicular to the top layer platform and the middle layer platform is fixed between the top layer platform and the middle layer platform; the two ends of steel beams for supporting the tubular upright post of the middle layer platform and the bottom layer platform can be fixed on the walls at two sides; more than three hydraulic hoisting systems are arranged by aiming at the top layer platform, the middle layer platform and the bottom layer platform of each unit; and each hydraulic hoisting system comprises a hoisting upright post, an upper hoisting box, a lower hoisting box and a pair of hydraulic cylinders which are connected between the upper hoisting box and the lower hoisting box. The template hoisting system for the building provided by the invention can be used for realizing that the platforms can be effectively hoisted by the height of a storey, thereby realizing the upward construction of core cylinder walls and other walls layer by layer; the safe reliability is high; and the falling phenomenon can be avoided.

Description

technical field [0001] The invention belongs to the field of construction machinery, and relates to a formwork lifting system for construction, in particular to an integrated system of a flexible hydraulic roof lifting platform and a combined formwork for super high-rise building core tube construction. Background technique [0002] At present, domestic super high-rise building construction (such as core tube construction) is widely used in hydraulic climbing formwork technology, integral steel platform electric lifter formwork lifting system, large-tonnage long-stroke cylinder integral jacking formwork technology (integral steel platform), etc. However, the climbing system of the hydraulic climbing formwork technology needs to be attached to the wall. When the wall becomes cross-sectional, transitional processing (such as climbing and resetting through the second floor) is required, which is cumbersome to operate; The system has no fall-proof structure, which is prone to fa...

Problems solved by technology

However, the climbing system of the hydraulic climbing formwork technology needs to be attached to the wall. When the wall becomes cross-sectional, transitional processing (such as climbing and resetting through the second floor) is required, which is cumbersome to operate; The system has no anti-fall structure, which is prone to fall hazards

In addition, the large steel platform is a whole. During construction, it is necessary to complete all the construction of a platform of a height before proceeding to the construction of the next floor. Flow operation cannot be realized, the construction is inflexible, and time is wasted. Moreover, the entire platform is large and difficult to realize. Corrective operation
