Description

Technical Field

[0001] The present invention relates to the technical field of large-span special-shaped steel structure construction, and particularly relates to a steel structure temporary support device with adjustable height. Background Art

[0002] During the construction of steel structures (such as industrial factories, bridges, stadiums, etc.), the temporary support device is the core equipment to ensure the structural stability and construction safety. Especially in scenarios such as the hoisting of large components, the closure of structures, or reinforcement and maintenance, it is necessary to dynamically adjust the support height according to the on-site working conditions to match the structural installation requirements. The existing temporary support technologies include traditional pad-type supports, screw jacks, and hydraulic synchronous jacking systems. However, the existing technologies still have the following defects: 1. Traditional pad-type support The height adjustment is achieved by stacking steel plates or steel sections with different thicknesses, which has significant drawbacks: Low adjustment efficiency: Each adjustment requires adding or removing pads, which is time-consuming and relies on lifting equipment; Stability risk: Gaps are likely to occur between multiple layers of pads, resulting in insufficient rigidity of the support system and potential instability under dynamic loads (such as wind loads and construction vibrations); Limited accuracy: The pads usually have a minimum unit of 10mm and cannot meet the need for millimeter-level fine adjustment.

[0003] 2. Screw jack Although it can achieve stepless height adjustment, it still has obvious deficiencies: Contradiction between bearing capacity and stroke: Long-stroke screws (>300mm) are prone to flexural deformation under high loads, restricting their application in large-tonnage steel structures (such as bridge main girders); Weak resistance to lateral forces: The slenderness ratio of the screw is too large, and the lateral stiffness is insufficient. Additional stabilizing cables need to be set, increasing the installation complexity; Poor operation safety: Workers need to operate below the support point during adjustment, posing a risk of falling objects from a height.

[0004] 3. Hydraulic synchronous jacking system Suitable for the overall lifting of large-span structures, but has limitations: High cost: It needs to be equipped with a pump station, sensors, and control systems, and is suitable for large-scale projects rather than local supports; Response hysteresis: Compression and leakage of the hydraulic oil circuit may cause non-synchronization of multi-point supports, inducing additional structural stresses.

[0005] In summary, it is difficult to balance the adjustment accuracy, operation convenience, load-bearing safety and economy of the existing temporary support devices. In particular, they cannot meet the frequent requirements for highly dynamic adjustments in modern steel structure construction (such as curved roof installation, deformation correction, etc.). For the above technical problems, there is an urgent need for a temporary support device with the capabilities of rapid and precise height adjustment, high rigidity and modular expansion to solve them.
