Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of steel structure, in particular to a self-adaptive deformation adjusting device for large-span steel structure. BACKGROUND

[0002] Steel structure is a very important building structure type in modern architecture, which has many advantages such as large strength, light weight, good rigidity, strong toughness and the like, so the application field is also very wide. With the continuous development of building technology, large-span steel structure is increasingly widely used in modern architecture. As a main load-bearing beam, profiled steel is connected to the support points at both ends of the main wall or beam. The main structure is first laid with profiled steel plate, then laid with steel bars, and then anchored and connected with the original structure periphery, and finally poured with concrete. However, large-span steel structure faces many challenges in use. Due to its large span, under the action of temperature change, wind load, live load and other factors, the structure is prone to large deformation. The traditional deformation control method is often to limit the deformation by increasing the rigidity of the structure, but this method will increase the self-weight of the structure and the cost, and the effect is not ideal in some cases. In addition, the existing deformation adjusting device is usually passive and cannot actively and adaptively adjust according to the real-time deformation of the structure, so it is difficult to effectively solve the deformation problem of large-span steel structure.

[0003] The prior art, with publication number CN111076921A, discloses a multi-environment anti-deformation detection device for steel structure, belonging to the technical field of steel structure detection. The device comprises a telescopic pressure rod for extruding the steel structure, a detection box for placing the steel structure, a sliding block slidingly connected to the detection box for supporting the telescopic pressure rod, and an adjusting frame slidingly connected to the detection box for supporting the steel structure and driving the sliding block to slide on the detection box. The sliding block is provided with two groups and located on both sides of the adjusting frame. The two sides of the sliding block are fixedly connected with first springs. The device can detect the anti-deformation capacity of the steel structure, and the detection result is more accurate and intuitive. The stability of the steel structure can be further improved during the detection process, and the device is convenient to assemble and disassemble, improving the work efficiency.

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