Description

Technical Field

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

[0002] For example, Chinese Utility Model Publication No. CN203867177U discloses an early-disassembly formwork support system, which includes a plane formwork, a formwork bracket, an early-disassembly column head, a crossbeam, and a base. The formwork bracket vertically supports the plane formwork, and the plane formwork includes a first formwork and a second formwork. The plane formwork is a steel formwork or a glued formwork; a plurality of first formworks and second formworks are arranged alternately, and a filler wood strip is set in the gap between the plane formworks. The formwork bracket is a fastener-type steel pipe bracket, and an early-disassembly column head is set at the upper end of the formwork bracket, and a base is set at the lower end of the formwork bracket. The early-disassembly column head is an adjustable screw-type lifting head. The formwork bracket and the early-disassembly column head are connected by threads, and a crossbeam is set at the upper end of the early-disassembly column head. When disassembling the support column, its base is not easy to disassemble, which is not conducive to the separation and separate disassembly of the support column and the base, and is not conducive to improving construction efficiency. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide an early disassembly support column base, which is easy to disassemble and helps to improve construction efficiency.

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

[0005] Transverse I-beams, which are laid parallel at intervals;

[0006] Longitudinal I-beams are laid in parallel at intervals and fixed vertically between two adjacent parallel transverse I-beams, and form a closed area with the transverse I-beams;

[0007] a cross-shaped I-beam disposed inside the closed area, with its ends fixed to the transverse I-beam and the longitudinal I-beam;

[0008] A triangular plate is welded to the corner of the upper flange in the middle of the cross-shaped I-beam, with spaces reserved between the triangular plate and the transverse I-beam, as well as between the triangular plate and the longitudinal I-beam;

[0009] A pad is placed in the middle of the cross-shaped I-beam and covers the triangular plate, with a gap reserved between it and the transverse I-beam and the longitudinal I-beam;

[0010] The bolt and nut assembly passes through the backing plate and the triangular plate and is tightened, with the bolt head at the upper end and the nut at the lower end.

[0011] The positioning ribs are fixedly arranged on the pad along annular interval angles.

[0012] With such a structure, the positioning ribs facilitate the positioning of the early-removal support column. The lower end of the early-removal support column has a flange that is connected to the positioning ribs. The triangular plate can prevent the bolt and nut assembly from drilling holes on the cross-shaped I-beam, thereby preventing the cross-shaped I-beam from reducing the bearing capacity of the cross-shaped I-beam. Spacing is reserved between the triangular plate and the horizontal I-beam, as well as between the triangular plate and the longitudinal I-beam, so that sufficient space is reserved for the installation and removal of the bolt and nut assembly. The positioning ribs locate the early-removal support column and are also convenient for welding with the early-removal support column.

[0013] As a further improvement of the present invention, ribs are provided in the transverse I-beams and the longitudinal I-beams.

[0014] With this structure, the ribs reinforce and support the transverse and longitudinal I-beams.

[0015] As a further improvement of the present invention, ear plates are provided on the transverse I-beam and the longitudinal I-beam.

[0016] With such a structure, it is convenient to support the inclined pull rod on the ear plate.

[0017] As a further improvement of the present invention, a pull rod is hinged on the ear plate.

[0018] With such a structure, the pull rod is convenient for hinged connection and early removal of the base of the supporting column.

[0019] As a further improvement of the present invention, a triangular block is arranged between the cross-shaped I-beam and the pad. The triangular block is located on the two coaxial branches of the cross-shaped I-beam. A pair of triangular blocks are connected by tension screws and tightened with nuts and washers; the pad abuts against the inclined surface of the triangular block.

[0020] Adopting such a structure makes it easier to remove the root of the early-removal support column during subsequent disassembly, so that the root of the early-removal support column can be removed to improve the disassembly efficiency.

[0021] As a further improvement of the present invention, rails are provided on both sides of the triangular block, and the rails are welded to the branches of the cross-shaped I-beam.

[0022] Such a structure makes it easy for the triangular block to retreat along a predetermined route when the supporting columns are removed early.

[0023] As a further improvement of the present invention, the triangular blocks are connected with ribs, and the ribs pass through a pair of triangular blocks and are placed under the pad.

[0024] With such a structure, when dismantling the early dismantling support column, the ribs are first pulled out and then the early dismantling support column is removed, and the ribs are convenient for supporting the middle part of the pad.

[0025] As a further improvement of the present invention, grooves are provided on the outer sides of the ribs for inserting side ribs.

[0026] With such a structure, the side ribs are padded on the sides of the pad to better support the pad, and the grooves facilitate positioning of the side ribs.

[0027] As a further improvement of the present invention, a middle rib block is provided between the two ribs, a U-shaped groove is provided on the upper surface of the middle rib block for the tension screw to pass through, and the upper surface of the middle rib block is spaced from the lower surface of the pad.

[0028] With this structure, after the pad is removed, it is supported by the middle ribs.

[0029] As a further improvement of the present invention, grooves are provided on the bottom surface of the triangular block, and rollers are distributed in the grooves.

[0030] With this structure, the bottom surface of the triangular block is easy to slide, reducing friction during unloading.

[0031] The utility model is easy to disassemble and is beneficial to improving construction efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
