Problems solved by technology

[0003] For the ultra-high-rise structure with a narrow core tube and large-scale construction machinery and equipment, it is difficult to meet the construction needs of the steel platform with a conventional structure. Therefore, it is necessary to study new structural forms of equipment to solve this construction problem

Embodiment Construction

[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. Advantages and features of the present invention will be apparent from the following description and claims. It should be noted that all the drawings are in a very simplified form and use imprecise scales, and are only used to facilitate and clearly assist the purpose of illustrating the embodiments of the present invention.

[0025] A brand-new door-type overall lifting steel platform system, this system is composed of steel platform, steel column climbing system, cylinder support system and large steel formwork system.

[0026] Such as figure 1 As shown, the steel platform is at the top of the entire system, serving as an operating platform for construction personnel and a place for stacking steel bars. The top main girder and bottom main girder of the steel platform are composed of H-shaped steel. The steel cover plate is covered ...

Abstract

The invention provides a gate-type integral lifting steel platform. The gate-type integral lifting steel platform comprises a steel platform, steel column climbing systems, a tube frame support system, steel large formwork systems and core tubes; the steel platform is located at the top part of the integral lifting steel platform; the steel platform includes a top main beam and a bottom main beam;each steel column climbing system includes a climbing guide rail upright column, an upright column base, a vertical climbing device and a steel column climbing power system; the tube frame support system includes an inner tube frame system; the inner tube frame system and the steel platform are connected into a whole; and each steel large formwork system includes steel large formworks, transversal enclosing purlins and vertical enclosing purlins. The gate-type integral lifting steel platform solves the problem of synchronous construction of vertical walls and horizontal beam and slab structures of the core tube structures to ensure the integrality of the structures; and it is guaranteed that large-scale mechanical equipment can be attached to the outer sides of the structures, and thus, the safety of the structures is ensured while the construction efficiency is increased.

Description

technical field [0001] The invention belongs to super high-rise construction machinery and equipment, in particular to the field of portal-type overall hoisting steel platforms. Background technique [0002] In the construction of super high-rise core tube structures, most of the integral steel platforms are used as the protection of the operation platform and elevator shaft. The main process of construction is mostly the construction of vertical shear walls first, followed by the filling of horizontal beam-slab structures. Before the overall structural system of the core tube is formed, this kind of construction process will weaken the structure's bearing and deformation resistance to a certain extent. In Nanjing Huaxin City Phase II project, the core tube structure is only a 22.5m square cube structure, and the plane size is small. Large-scale tower cranes cannot be installed in the core tube. They need to be attached to the outer shear wall of the core tube. For the enti...
