Problems solved by technology
[0004] The purpose of the present invention is to provide a construction method for the steel column and tube frame alternate support type hydraulic climbing integral steel platform through the truss layer, so as to solve the problem that the truss layer cannot be erected by the conventional climbing method in the prior art, and rely on the steel platform formwork system to successfully realize the construction of the truss layer. The erection of the truss layer ensures the smooth climbing of the steel platform formwork system

Embodiment Construction
[0030] The core idea of the present invention is that when the steel column frame alternately supported hydraulic climbing integral steel platform is being constructed on the truss layer, the connecting beams on the steel platform system are removed step by step, so that the integral steel platform has a cavity, and the composition is formed through the cavity. The components of the truss layer are hoisted into the core tube respectively, and the components of the truss layer are connected and assembled in the fully enclosed operating space formed by the steel platform formwork system to form the truss layer. The above-mentioned construction method relies on the steel platform formwork system to be installed and lifted layer by layer along the vertical section of the truss layer, avoiding the disassembly and assembly of the steel platform formwork system at high altitude, and the entire construction process is carried out in a fully enclosed space, maximizing The construction...

The invention provides a steel column drum rack support type hydraulic lifting overall steel platform cross truss layer construction method. A steel column drum rack support type hydraulic lifting overall steel platform comprises a steel platform system and a support system. The support system comprises a drum rack support and a steel column support. The steel platform system comprises a plurality of steel platform units and connecting beams. The steel platform units are connected into an overall steel platform through the connecting beams. A steel cover plate is disposed on the overall steel platform to form a construction platform. The drum rack support is fixed blow the overall steel platform. The steel column support is located at the upper end of a core drum concrete structure. The method includes: removing the steel cover plate and the connecting beams interfered with a truss layer step by step, hanging all truss layer rod components into the core drum through holes step by step, remounting the removed steel cover plate and the connecting beams when each step of hanging is completed, connecting the truss layer components, and allowing the components to be fixedly connected with the core drum so as to form the truss layer. By the method, safe construction is guaranteed effectively, and construction period is shortened.
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 a core tube of a high-rise and super high-rise building, in particular to a construction method for a steel column tube frame alternately supported hydraulic climbing integral steel platform passing through a truss layer. Background technique [0002] my country's super high-rise buildings have developed rapidly in recent years. For extremely high super high-rise buildings, the overall self-elevating steel platform formwork system is usually used, such as the Chinese patent ZL200610118944.4, which is named: steel column supported integral self-elevating steel platform Platform scaffolding formwork system. The steel-column frame alternately supported hydraulic climbing integral steel platform mainly includes: a steel platform system, a scaffolding system, a steel column support system, a power control system and a l...
