Description

Technical Field

[0001] The utility model relates to the technical field of steel structures, and more specifically to a steel structure box column resistant to external extrusion. Background Art

[0002] Steel structure box columns play an important role in construction and bridge engineering. Their main purpose lies in their load-bearing capacity. Box columns are composed of four welded steel plates, and are square or rectangular in shape, with a large load-bearing capacity. They can not only withstand vertical loads, but also horizontal loads and vibration loads. Therefore, they are widely used in high-rise buildings, large-span structures, subway stations, airports, bridges and other projects.

[0003] In the existing public documents, the patent publication number CN212561892U discloses a steel structure box column connection node, which is installed and fixed by high-strength bolts, gourd holes and latch washers, which improves the efficiency of installation and disassembly, improves the stability of the connection node, avoids breakage, and reduces the cost of manpower and material resources; the steel structure box column has the following defects:

[0004] During the use of steel structure box columns, once the outside is hit by external force, it will cause the outside to deform and then dent inward. Therefore, the steel structure box column is very likely to cause internal deformation and damage due to external impact, and its resistance to external extrusion is poor. Therefore, it is necessary to provide steel structure box columns that are resistant to external extrusion. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides a steel structure box column resistant to external extrusion.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a steel structure box column resistant to external extrusion, comprising a box structure beam, a base welded to the bottom end of the box structure beam, a pillar fixedly connected to the top end of the base and located inside the box structure beam, and a multi-directional anti-extrusion mechanism is provided on the outer wall of the pillar; the multi-directional anti-extrusion mechanism comprises a reinforcement ring fixedly arranged on the outer wall of the pillar, and a support ring is welded to the outer wall of the pillar and located above the reinforcement ring; fixedly connected V-shaped support beams are provided on both sides of the outer wall of the pillar, and two inclined support plates are fixedly connected to the opposite sides of the two V-shaped support beams; reinforcement blocks are fixedly connected to both sides of the V-shaped support beam, and each of the top and bottom ends of the reinforcement block is fixedly connected to a reinforcement strip.

[0007] Preferably, the top surface of the support ring is higher than the top surface of the reinforcement ring, and the cross-sectional shapes of the reinforcement ring and the support ring are both set to be circular, the center point of the inner wall of the support ring and the center point of the inner wall of the reinforcement ring are in the same vertical line position, the support ring and the reinforcement ring are welded to the V-shaped support beam, and the support ring and the reinforcement ring are symmetrically arranged about the middle part of the V-shaped support beam, both sides of the box-shaped structural beam are fixedly connected with inclined support blocks, the bottom ends of the two inclined support blocks are welded to the top of the base, the top of the base and near its four corner lines are provided with mounting holes, and the cross-sectional shape of the mounting holes is circular.

When the outside of the box structure beam is subjected to extrusion impact force, the force is applied to the box structure beam through the outside. The pillar supports the support ring and the reinforcement ring. The inclined support plate provides support force for the V-shaped support beam, thereby increasing the stability of the V-shaped support beam. The reinforcement block provides support force for the two reinforcement strips. The two reinforcement strips can implement front and rear support for the inside of the box structure beam, while the two V-shaped support beams can implement left and right support reinforcement for the inside of the box structure beam. The inside of the box structure beam has a stronger ability to resist external extrusion, thereby avoiding deformation and damage of the box structure beam.

The two reinforcement arc bars are symmetrically arranged about the hexagonal column, and the cross-sectional shape of the reinforcement arc bar is an arc.

[0010] In this technical solution, the supporting ring supports the reinforcement column, the corner support block reinforces and supports a corner position of the inner wall of the box-shaped structural beam, the hexagonal column supports the reinforcing ribs, and the reinforcing ribs reinforce the corner at another position of the inner wall of the box-shaped structural beam. The two reinforcing arc strips respectively support the two connecting support blocks, and the two connecting support blocks can reinforce and support the other two corner points of the inner wall of the box-shaped structural beam.
