Description

Technical Field

[0001] The invention relates to the technical field of steel structures, in particular to an adaptive deformation adjustment device for a large-span steel structure. Background Art

[0002] Steel structure is a very important type of building structure in modern buildings. It has many advantages such as high strength, light weight, good rigidity and strong toughness. Therefore, its application field is also very wide. With the continuous development of construction technology, the application of large-span steel structure in modern buildings is becoming more and more extensive. Steel section is the main load-bearing beam, which is connected to the supporting points at both ends of the main wall or beam. The main structure is first laid with corrugated steel plate, then with steel bars, and then anchored and connected with the surrounding of the original structure, and finally poured with concrete. However, large-span steel structure faces many challenges during use. Due to its large span, the structure is prone to large deformation under the influence of various factors such as temperature changes, wind loads, and live loads. Traditional deformation control methods often limit deformation by increasing the stiffness of the structure, but this method will increase the deadweight of the structure, increase costs, and in some cases the effect is not ideal. In addition, the existing deformation adjustment device is usually passive and cannot be actively and adaptively adjusted according to the real-time deformation of the structure, making it difficult to effectively solve the deformation problem of large-span steel structure.

[0003] The prior art, with announcement number CN111076921A, discloses a multi-environment anti-deformation detection device for steel structures, belonging to the technical field of steel structure detection. A multi-environment anti-deformation detection device for steel structures comprises a telescopic pressure rod, which is used to extrude the steel structure, and also comprises: a detection box for placing the steel structure; a sliding block, which is slidably connected to the detection box and is used to support the telescopic pressure rod; an adjustment frame, which is slidably connected to the detection box and is used to support the steel structure and is used to drive the sliding block to slide on the detection box; wherein the sliding block is provided with two groups and is respectively located on both sides of the adjustment frame, and both sides of the sliding block are fixedly connected with a first spring; a driving component; a transparent plate; the present invention can detect the anti-deformation ability of the steel structure, multi-point detection, and the detection result is more accurate and more intuitive, and the stability of the steel structure can be further improved during the detection process, which is convenient for assembly and disassembly, and improves work efficiency.

[0004] Although the above application can further improve the stability of the steel structure, facilitate assembly and disassembly, and improve work efficiency, in actual application, it is inconvenient to monitor the structural deformation during use, which causes the structural deformation to seriously affect the normal use of the structure and reduce the convenience of using the device.
