Inner roof external climbing type formwork construction platform for super high-rise building construction

Abstract

The invention discloses an inner roof external climbing type formwork construction platform for super high-rise building construction. The inner roof external climbing type formwork construction platform comprises a hydraulic creeping formwork system arranged on the outer side of a building and located on building walls and a jacking platform system arranged on the inner side of the building and located between adjacent building walls. The jacking platform system comprises a climbing device, an operating platform arranged on the climbing device and wall-attached embedder parts installed on the building walls and used for the climbing device to climb and attach. The hydraulic creeping formwork system adopted on a building external wall and the jacking platform system adopted on the inner side of the building and located between the building walls simultaneously operate to replace a traditional integral jacking type construction platform, horizontal supporting steel beams are not needed, oil cylinder climbing can be achieved only by installing the wall-attached embedder parts on the building walls, the total height of the construction platform and a supporting frame body of the platform is decreased, and a construction difference between a vertical structure and a horizontal structure is decreased, so that the hydraulic climbing system does not influence horizontal structure construction.

Description

technical field [0001] The invention relates to the field of super high-rise building construction, in particular to an inner top and outer climbing formwork construction platform used for super high-rise building construction. Background technique [0002] In the reinforced concrete construction of walls, core tubes, chimneys, water towers and other buildings of high-rise buildings, the overall lifting steel platform scaffolding system is mostly used. Cooperate figure 1 and figure 2 As shown, the system is supported by the support column (lattice column) inserted in the wall, powered by the elevator, the main beam is made of large-section H-shaped steel, and the formwork and scaffolding system are hung below. A closed operating platform with a certain bearing capacity is formed on the operating surface of the core tube. [0003] However, the overall lifting cylinder platform scaffolding system has the following defects: [0004] 1. Since the steel platform is integrall...

AI Technical Summary

Problems solved by technology

[0004] 1. Since the steel platform is integrally fixed, the platform must be cut when encountering structural outrigger trusses and connecting beams, which increases the difficulty of construction, otherwise it will not be possible to construct related horizontal structures;

[0005] 2. Lattice columns must be embedded in the structure and cannot be recycled, resulting in waste of materials and affecting the construction of horizontal structures;

[0006] 3. The construction method usually used in the construction of super high-rise core tubes is: the vertical structure goes first, and the horizontal structure lags behind the vertical wall by more than 10 floors, resulting in a large gap between the vertical and horizontal structures, facing severe fire safety hazards and structural problems. Stress problem

Moreover, the safety protection at the bottom of the top formwork system is relatively difficult, and falling objects from high altitudes will bring serious safety hazards to the structural construction of the lower horizontal beam slab
