Description

Technical Field

[0001] The utility model relates to the field of early dismantling formwork, in particular to an early dismantling support column. Background Art

[0002] Chinese Utility Model Publication No. CN203867177U discloses an early-disassembly formwork support system, comprising a planar formwork, a formwork support, an early-disassembly column head, a crossbeam, and a base. The formwork support vertically supports the planar formwork, which includes a first formwork and a second formwork, each of which is a steel formwork or a plywood formwork. Several first and second formworks are arranged alternately, with filler wood strips positioned in the gaps between the planar formworks. The formwork support is a fastener-type steel pipe support, with an early-disassembly column head positioned at the upper end and a base positioned at the lower end. The early-disassembly column head is an adjustable screw-type lifting head, and the formwork support and the early-disassembly column head are threadedly connected. A crossbeam is positioned at the upper end of the early-disassembly column head. The steel pipe column at the bottom section is not easily connected to the base, making it difficult to secure the steel column. Utility Model Content

[0004] In order to solve the above problems, an early dismantling support column is adopted, which includes:

[0005] Multiple sections of steel columns are set in upper and lower sections and spliced together;

[0006] A flange is fixedly mounted on the end of a single-section steel column;

[0007] Reinforcement plate, which is welded between the steel column and the flange;

[0008] Corbels, which are fixed on both sides of the top steel column;

[0009] Bolt and nut assemblies, which are fastened to adjacent spliced flanges;

[0013] As a further improvement of the present invention, a first hanging ring is distributed on the steel column.

[0014] With such a structure, when the steel column is dismantled in sections, the first lifting ring cooperates with the lifting rope to facilitate the dismantling and lowering of the sectioned steel column.

[0015] As a further improvement of the present invention, the corbel includes an upper chord, a lower chord, a vertical web and a diagonal web. The upper chord and the lower chord are fixed with a first base plate at one end close to the steel column, and a second base plate is fixed at the end away from the steel column. The first base plate is fixed to the steel column.

[0016] With such a structure, the first bottom plate and the second bottom plate are used to splice the steel columns and trusses respectively.

[0023] As a further improvement of the present invention, the first base plate is connected with a tension screw assembly, and the tension screw assembly is connected with the steel column and the first base plates on both sides thereof.

[0024] Such a structure makes the upper corbel of the steel column have a higher bearing capacity.

[0025] As a further improvement of the present invention, partitions are provided in the top steel columns, which are welded in layers in the top steel columns and are located below and above the tension screw assembly. The upper partitions are opened and filled with dense concrete.

[0026] With such a structure, the deformation of concrete due to thermal expansion and contraction is small, and after pouring, the tension screw assembly is further strengthened to prevent it from loosening.

[0027] As a further improvement of the present invention, the clamps are arranged in layers, with screws fixed between the upper and lower clamps, and lugs slidingly passed through the screws, and nuts are threadedly connected to the upper and lower sides of the lugs.

[0028] With such a structure, the tightness of the pull rod can be adjusted to ensure that it is in a tight state during use.

[0029] As a further improvement of the present invention, a horizontal plate is arranged inside the column head of the top section steel column, the vertical plate is fixedly connected to the horizontal plate, the cover plate is fixedly connected to the vertical plate, and concrete is poured densely between the horizontal plate and the cover plate.

[0030] With this structure, it is easy to install the bracket on the cover plate, and the vertical plate prevents the cover plate from being concave. After pouring concrete, the deformation is smaller.

[0031] The utility model is easy to assemble, and the bottom section of the steel pipe column is conveniently connected to the base, which is convenient for pre-fixing the bottom section of the steel pipe column and then welding or bolting it, which is beneficial to improving construction efficiency, improving the quality of welding or bolting, ensuring that the steel column is vertical during the fixing process, and preventing tilting.
