[0002] Bridges generally refer to structures built across rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to buildings that cross mountain streams, poor geology, or meet other transportation needs to make passage more convenient; support brackets are commonly used tools in bridge construction;

[0003] For example, patent number CN202323108271.2 is a support bracket for bridge construction. The technical problem is that the support system at the concrete pouring site during bridge construction is easily deformed and unstable due to the instantaneous impact force generated by pouring, which affects construction safety.

The rotation of the driven gear 6 can drive the threaded rod 7 to rotate. Through the setting of the limiting plate 21 and the limiting groove 22, the movement trajectory of the threaded sleeve 8 is limited, so that the rotation of the threaded rod 7 can drive the threaded sleeve 8 to move, and the movement of the threaded sleeve 8 can drive the push plate 9 The lower support column 11 can be pushed up to move, and the two adjustment frames 3 can adjust the support at the same time to ensure the short-distance adjustment of the support bracket. The spring telescopic support seat 10 at the center uses its internal spring support effect to ensure the support effect at the center of the lower support column 11. If the height of the long-distance support bracket needs to be adjusted, the upper support column 12 can be connected to the lower support column 11, that is, connected through the abutment and clamping effect between the cross locking groove 25 and the cross locking plate 24, and new different ones can also be added between the upper support column 12 and the lower support column 11. The length of the support column is to allow the receiving support seat 16 to abut against the bottom of the construction beam of the bridge. In order to enhance the extension of the construction support surface at the bridge construction site, the extended side panel 15 can be inserted into the inner wall of the connecting side groove 14 for clamping and positioning, and the receiving support seat 16 on the top of the extended side panel 15 and the stabilizing abutment plate 13 can play a supporting role, that is, the shock absorber 26 and the buffer pad 27 can play a buffering support effect, and the dustproof stretch sleeve 28 can be in a surrounding state to perform dustproof protection on the internal structure, and the movement of the entire support bracket and the height support adjustment effect can be achieved without electric adjustment.
