Embodiment 1

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

[0068] The truss platform system I is mainly composed of several standard Bailey frames 1, which are connected and assembled into primary and secondary trusses 101, 102; Connected to form a main frame, connect a rectangular peripheral frame 103 on the periphery of the main frame through the standard Bailey frame 1, and connect secondary The truss 102, the main truss 101, the secondary truss 102 and the peripheral frame 103 together constitute a truss platform system I with a palace-shaped...

Embodiment 2

[0083] Such as figure 1 , 3 As shown, in the dynamic support jacking system III, the upper and lower box girders 9 are connected to each other through a pair of jacking cylinders 5, and a pair of jacking cylinders 5 are symmetrically distributed along the center line of the box girder 9; the jacking cylinders 5 The upper and lower layers of box girder 9 are connected by flange bolts, and the flange and box girder 9 are connected by welding. The jacking cylinder 5 is equipped with a steel cylinder (the steel cylinder protects the jacking cylinder 5), and the steel cylinder and the upper layer The box girder 9 is welded and connected; the upper box girder 9 is fixedly connected with two lattice support steel columns 7, and the two lattice support steel columns 7 are respectively located directly above a pair of jacking cylinders 5; the box girder 9 The two ends of each are connected with a corbel 901 (the corbel 901 is inserted into a preset hole on the wall 10 of the core tube...

Embodiment 3

[0089] Such as Figure 10-14 As shown, the protective operation frame 3 includes a plurality of single-layer hangers connected from top to bottom, and the uppermost single-layer hanger is hung on the lower chord of the standard Bailey frame 1; the single-layer hanger The frame includes four vertical rods 301, two cross rods 303, a scaffold board 304, a facade protection net 305 and an inner flap 306, and the lower end of each vertical rod 301 is provided with a vertical rod connector 302, and the vertical rod The upper end of the connector 302 is telescopically fixedly connected to the lower end of the vertical rod 301; the four vertical rods 301 are in pairs, and each group of two vertical rods 301 is fixedly connected by a cross bar 303, and the two ends of the cross rod 303 The middle parts of the pole connectors 302 at the lower ends of the two poles 301 are respectively detachably and fixedly connected, and the two poles 301 in each group are vertically parallel and symme...

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 ...
