A composite steel structure with irregular column shape

Abstract

This utility model discloses a composite steel structure for irregularly shaped columns, including a right-side fixing plate and a right-side reinforcing plate. A threaded shaft is rotatably connected to a groove on the fixing block. This utility model allows for improved connection strength by sliding the fixing base plate into the groove formed by the fixing block, rotating the handle to rotate the threaded shaft, and ultimately causing the sliding block to slide out of the fixing block and engage the fixing base plate. Rotating the connecting rod engages it in the through holes of the fixing block, fixing base plate, and support block, strengthening the connection, improving overturning resistance, and exceeding the strength requirements of the specifications, thus eliminating structural safety hazards. A left-side I-beam is fitted onto the fixing device. Rotating the rotating nut disengages the threaded rod, pulls the activation block, and retracts the threaded rod into the sliding groove, allowing the left-side I-beam to be disassembled. The disassembly and installation process does not require special tools, making operation simple and labor-saving, and improving construction efficiency.

Description

Technical Field

[0001] This utility model relates to the technical field of irregular column composite steel components, and in particular to an irregular column composite steel component. Background Technology

[0002] Irregularly shaped composite steel components combine superior structural performance, high space utilization, and convenient construction, making them a key choice for modern high-performance building structures. Through the synergistic action of steel and concrete, these components fully leverage the high tensile strength of steel and the excellent compressive strength of concrete, significantly improving the load-bearing capacity and overall structural rigidity, thus enhancing resistance to wind loads and seismic forces. The cross-sectional shape of the irregularly shaped columns can be flexibly designed according to the building layout, allowing them to be embedded within the wall, avoiding the protrusion of traditional rectangular columns. This improves the integrity and efficiency of the interior space, making them particularly suitable for residential buildings and buildings with high aesthetic requirements. Furthermore, the composite components can reduce cross-sectional dimensions and structural weight, thereby reducing foundation loads and seismic forces.

[0003] However, the commonly available irregular-shaped column composite steel components have significant drawbacks: First, the connection between the bottom of the irregular column and the foundation has poor stability and weak overturning resistance, making it prone to displacement or settlement under load. Its strength reserve is far below the specifications, posing a significant structural safety hazard. Second, the design of the I-beam connection nodes lacks flexibility, and the disassembly and installation processes are highly dependent on specialized tools and equipment, making the operation cumbersome, time-consuming, and labor-intensive. This not only increases the difficulty of on-site construction but also seriously affects construction efficiency and economy due to the high cost and poor versatility of the tools. Therefore, designing an irregular-shaped column composite steel component is essential. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a composite steel component of an irregular column, including a support block, a fixing block, a right fixing plate, a right reinforcing plate, and a left fixing plate. A threaded shaft is rotatably connected to a groove in the fixing block, and a handle is fixedly connected to the threaded shaft.

The threaded rod is slidably connected to the through hole in the fixing device and the left I-beam, and the activation block is slidably connected to the sliding groove.

[0006] As a further technical solution of this utility model, a fixing block is fixedly connected to the support block, a limiting plate is fixedly connected to the fixing block, a fixing base plate is fixedly connected to the fixing block, and a connecting rod is rotatably connected in the through holes opened on the fixing block, the fixing base plate and the support block.

[0007] As a further technical solution of this utility model, a connecting column is fixedly connected to the fixed base plate, and a right fixed plate and a left fixed plate are fixedly connected to the connecting column respectively.

[0008] As a further technical solution of this utility model, a right-side reinforcing plate and a left-side reinforcing plate are fixedly connected to the connecting column, a right-side fixing plate is fixedly connected to the right-side reinforcing plate, and a left-side fixing plate is fixedly connected to the left-side reinforcing plate.

[0009] As a further technical solution of this utility model, a left-side I-beam is sleeved on the fixing device, and a rotating nut is threaded onto the threaded rod.

[0010] As a further technical solution of this utility model, a first connecting device and a second connecting device are fixedly connected to the right fixing plate, and a right I-beam is fixedly connected to the first connecting device.

[0011] As a further technical solution of this utility model, the second connecting device is fixedly connected to the right-side I-beam, and the right-side I-beam is tightly attached to the right-side fixing plate.

[0012] This utility model provides a composite steel structure for irregularly shaped columns, which has the following advantages: By sliding the fixed base plate into the groove formed by the fixed block, rotating the handle drives the threaded shaft to rotate, ultimately causing the sliding block to slide out of the fixed block and lock the fixed base plate in place. The first spring provides a certain tension force, which helps to improve the connection strength. Rotating the connecting rod engages it in the through holes opened in the fixed block, fixed base plate, and support block, which strengthens the connection, improves the anti-overturning ability, and has a strength reserve higher than the standard requirements, eliminating potential structural safety hazards. A left-side I-beam is sleeved on the fixing device. Rotating the rotating nut causes the rotating nut to turn out of the threaded rod, pulling the activation block retracts the threaded rod into the sliding groove, and the left-side I-beam can be disassembled. The disassembly and installation process does not require special tools and equipment, making the operation simple and labor-saving, reducing the difficulty of on-site construction, and improving construction efficiency.
