Embodiment Construction

[0065] Examples see figure 1 As shown, this low-position and less-fulcrum modular overall jacking steel platform formwork system includes the low-position jacking formwork system jacking device supported on the core tube shear wall 8, which is connected to the low-level jacking system through the support column 3. The steel platform 1 on the jacking device of the formwork system, and the hanger 2 and the formwork 7 suspended on the steel platform 1, in this embodiment, the formwork 7 is a shaped large steel formwork. The entire low-level and less-fulcrum modular overall jacking steel platform formwork system often requires three or four sets of low-level jacking formwork system jacking devices.

[0066] see Figure 18-20 , the supporting column 3 is a standardized lattice column, including an upper pad beam 31 connected with the steel platform 1, a lower pad beam 32 connected with the upper support beam 5, and connected between the upper pad beam 9 and the lower pad beam 32 ...

Abstract

The invention relates to a low-position few-fulcrum modularized integral jacking steel platform formwork system. A supporting upright column of the system is a standardized lattice column and comprises an upper bearing beam connected with a steel platform, a lower bearing beam connected with an upper supporting cross beam and a lattice column main body connected between the upper bearing beam andthe lower bearing beam, the lattice column main body comprises four column limbs, and each column limb is formed by splicing standard segmented column limbs one by one in an end-to-end connection mode through bolts. A jacking cylinder of the system is inverted and penetrates through the upper supporting cross beam main body from bottom to top. The steel platform of the system is an assembly type changeable steel truss platform and comprises main stressed trusses, auxiliary stressed trusses and support bars between the trusses. A pylon of the system is an adjustable pylon and comprises a skeleton and a steel spring board fixed on the skeleton. The formwork system realizes the modularization of each assembly and the standardization of operations, can be repeatedly and circularly used on different buildings and can be adjusted along with the height of the buildings. Moreover, the formwork system can effectively reduce construction cost, reduce construction difficulty and increase workingefficiency.

Description

technical field [0001] The invention relates to a formwork system, in particular to a low-position overall jacking formwork system which can be used in the construction of high-rise and super high-rise buildings. Background technique [0002] In the core tube construction of existing high-rise and ultra-high-rise building structures, it is rare to use a low-level overall jacking formwork system, which has only been used in individual projects, including steel platforms, supporting columns, hangers, jacking cylinders, Several parts such as support beams and formwork. [0003] The support columns in the existing low-level overall jacking formwork system usually use fixed-length large-diameter steel pipe columns as the vertical support columns. The number of such support columns is small and the design bearing capacity is large. However, the existing support columns need to be customized according to the structural characteristics of different buildings, and are connected by w...
