Embodiment Construction

[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0032] Specific embodiments, such as a super high-rise building with a height of 319m, a core tube area of ​​322m2 in the shape of a square, and a standard storey height of 4.5m. If the traditional steel column-supported steel platform formwork system is used, 15 steel columns with a length of 300m are required to be supported, and these steel columns must be buried in the concrete structure, which cannot be recycled, and the construction cost is relatively high.

[0033] In order to save construction costs, the steel column frame of the present invention is used to alternately support the overall climbing steel platform formwork system for construction, such as Figure 1~6 As shown, the steel column frame of the present invention alternately supports the overall climbing steel platform formwork system, which includes a steel platform 1, a for...

Abstract

The invention discloses a system for alternatively supporting a whole lifting steel platform formwork by a steel column casing rack. The system comprises a steel platform, a template system, a scaffold system, a support system and a climbing system, wherein the support system comprises a casing rack support and a steel column support; the climbing system comprises climbing boosts and a hydraulic system; preformed core column holes are distributed on a core cylinder structure at intervals along the height direction; the casing rack support is fixedly arranged under the steel platform; the steel column support is fixed in the preformed core column holes under the construction state to serve as the support of a steel platform formwork under the construction state; under the climbing state, the steel column support is fixed to the upper end part of the concrete core cylinder structure and is used as the support of the steel platform formwork under the climbing state; and under the construction state, the steel column support is fixed to the steel platform by the climbing boosts. According to the system, the steel platform formwork system can greatly reduce the construction cost and save the engineering material by the whole hydraulic climbing supported by the tool type steel columns.

Description

technical field [0001] The invention belongs to the technical field of building construction, and relates to a high-rise and super high-rise building core tube construction equipment and a construction method, in particular to a formwork system and a construction method for an integral climbing steel platform alternately supported by a steel column tube frame. Background technique [0002] At present, the core tube construction of existing high-rise and super high-rise buildings usually adopts the integral self-elevating steel platform formwork system. For example, our company has authorized a patent, the patent number is ZL200610118944.4, and the invention name is: steel column supported integral self-elevating steel platform foot Hand formwork system, which mainly includes steel platform, hanging scaffolding, steel column support, formwork system, lifting system, etc. The formwork system will be able to combine the steel platform in the work area, the construction work sca...
