Embodiment Construction
[0032] Examples see figure 1 , Figure 15 As shown, the low-level jacking formwork system includes an upper support beam 5 and a lower support beam 6 supported on the core tube shear wall 8, and a jacking cylinder 4 detachably connected between the upper support beam 5 and the lower support beam 6 , the steel platform 1 connected above the upper support beam 5 is supported by a standardized lattice column 3 used for the low-level jacking formwork system, and the hanger 2 and the formwork 7 suspended on the steel platform 1 . The steel platform is an ordinary steel frame platform or an assembled variable steel truss platform, and the hanger is an ordinary hanger or an adjustable hanger.
[0033] see Figure 2-4 , the present invention is connected between the steel platform 1 and the upper support beam 5 of the low-position jacking formwork system, including the upper pad beam 9 connected with the steel platform 1, the lower pad beam 10 connected with the upper support beam 5...

The invention relates to a standardized lattice column for a low jack-up formwork system. The standardized lattice column comprises an upper template beam connected with a steel platform, a lower template beam connected with an upper supporting beam and a lattice column main body connected between the upper template beam and the lower template beam, wherein the lattice column main body comprises four column limbs; each column limb is formed by connecting the heads and the tails of segments of standard segmented column limb assembling pieces through bolts; each node of standard node column limb assembling piece comprises joist steel, an upper blanking plate welded at the upper end of the joist steel, a lower blanking plate welded at the lower end of the joist steel, and gusset plates distributed and welded on joist steel web plates at intervals; the flange of the joist steel is connected with a connecting lug plate by bolts; lacing bars are detachably connected between two adjacent column limbs; and the lacing bars comprise diagonal bracing steel and cross bracing steel. The lattice column is convenient to assemble and disassemble, facilitates process adjustment, can shorten a construction period, can be returnably used and can reduce construction cost.
Description
technical field [0001] The invention relates to a standardized lattice column for a low-level jacking formwork system. Background technique [0002] In the core tube construction of existing high-rise and super high-rise building structures, it is rare to use the low-level jacking formwork system, and it has only been used in individual projects. In this type of formwork system, the support column usually uses a fixed-length large-diameter steel pipe column as the vertical support column. The existing supporting columns are specially customized according to the structural characteristics of different buildings, and are connected by weld seams. The construction period is long, the construction cost is high, the installation and disassembly are difficult, and they cannot be used repeatedly, so the construction cost and construction difficulty are increased. Contents of the invention [0003] The purpose of the present invention is to provide a standardized lattice column fo...
