Example Embodiment

[0066] Example 1

[0067] Such as figure 1 , 2 , 3 and 10, a standard Bailey frame assembled jacking formwork system is mainly composed of a truss platform system I, a suspension system II and a power support jacking system III. The power support jacking system III It is fixedly supported on the core tube wall 10, and its upper part is connected to the truss platform system I through the lattice support steel column 7, and the suspension system II is hung on the truss platform system I;

[0068] The truss platform system I is mainly composed of a number of standard berets 1, which are connected to each other and assembled to form primary and secondary trusses 101, 102; the main trusses 101 are connected vertically and horizontally through the beret Connected into a main frame, connected to a rectangular peripheral frame 103 on the periphery of the main frame through the standard Beret 1, between the main truss 101 and the main truss 101 and between the main truss 101 and the perip...

Abstract

The invention relates to a standard Bailey truss assembling type jacking formwork system. The standard Bailey truss assembling type jacking formwork system is characterized in that the standard Bailey truss assembling type jacking formwork system is mainly composed of a truss platform system, a hanging system and a power supporting and jacking system, the power supporting and jacking system is fixedly supported by a core tube wall, the upper portion of the power supporting and jacking system is connected with the truss platform system through lattice supporting steel columns, the hanging system is hung on the truss platform system, the truss platform system is mainly composed of a plurality of standard Bailey trusses, the standard Bailey trusses are mutually connected to form main trusses and secondary trusses, the main trusses are connected longitudinally and transversely through Bailey truss connecting pieces to form a main framework, the Bailey trusses are connected on the periphery of the main framework to form a rectangular peripheral framework, and the Bailey truss connecting pieces are connected with the upper ends of the lattice supporting steel columns. According to the standard Bailey truss assembling type jacking formwork system, the system is composed of the standard Bailey trusses, construction and assembly are fast and convenient, repeated utilization is available, and the adaptability is high.

Description

technical field [0001] The invention relates to a core tube construction formwork system for a building with an outer frame and an inner cylinder structure, in particular to a standard Bailey frame assembled jacking formwork system. Background technique [0002] Currently in a period of rapid development of high-rise buildings, taller and taller buildings continue to emerge, and the application of jacking formwork systems (referred to as "top formwork systems") in the construction of super high-rise concrete structures is becoming more and more popular. In the construction of the core tube structure of a super high-rise building with an outer frame and an inner tube, the jacking formwork system cannot better meet the characteristics of tight project schedules and complex changes in the building structure in actual construction, and it is highly dependent on tower cranes. Cross-effects of other processes. [0003] The components used in the top formwork system are all steel ...
