Synchronous construction method for horizontal and vertical structures of super high-rise building

Abstract

The invention discloses a synchronous construction method for horizontal and vertical structures of a super high-rise building. According to the synchronous construction method, a hydraulic creeping formwork system is adopted on the outer wall of the super high-rise building, and a jacking platform system is adopted between two building walls on the inner side of the super high-rise building; when being operated at the same time, the two systems can replace a conventional overall jacking construction platform as a construction platform, thereby reducing the overall weight of a construction platform and the burden of a hydraulic jacking system, achieving higher flexibility, and improving the construction speed; as the light-weight jacking platform system is configured, a small-sized oil cylinder can be adopted; accordingly, no horizontal supporting steel beam is needed, oil cylinder climbing can be achieved as long as wall-attached embedded parts are mounted on the building walls, the total height of the construction platform and a supporting frame body can be reduced, the construction gap between the vertical and horizontal structures can be narrowed, and the construction of the horizontal structure can be prevented from being influenced by a hydraulic climbing system; and the jacking platform system adopted on the inner wall of the super high-rise building is prevented from penetrating through the building walls, and the gap between the construction platform and a reinforcing bar colligation operation surface is equal to the height of one floor, thereby achieving convenient reinforcing bar transfer and colligation.

Description

technical field [0001] The invention relates to the field of super high-rise building construction, in particular to a method for synchronously constructing horizontal and vertical structures of super high-rise buildings. 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 integrally fixe...

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
