Description

Technical Field

[0001] The present invention relates to the technical field of steel support bearings, and in particular to a subway station steel support assembled bearing and a construction method thereof. Background Art

[0002] During the construction of deep foundation pits for subway stations, steel supports are widely used because they have advantages over concrete supports, such as faster construction speed, reusability, lightness and flexibility.

[0003] In the prior art, steel supports used in subway stations are usually fixed to tie beams by clamps. The existing clamps are of fixed sizes. When connecting steel supports of different thicknesses, clamps of different sizes are required. Generally, it is necessary to purchase clamps of multiple sizes for use, which is expensive.

[0004] Furthermore, existing clamps are prone to sliding up and down after being tightened, resulting in poor tightness and stability. Another contributing factor to the poor stability is that the clamp is too narrow. A narrow clamp width results in a relatively small contact area, while making the clamp too wide is relatively expensive. When tightening and loosening existing clamps, the nut and screw on the locking bolt must be completely separated before the clamp can be removed from the steel support. This process is cumbersome and can easily cause the nut or screw to be lost. During the installation process, the clamp must be welded at high altitude, which not only makes welding difficult due to the narrow working surface, but also poses a significant safety hazard.
