Prestressed supporting steel structure based on large-span foundation pit engineering
The invention discloses a prestress type supporting steel structure based on large-span foundation pit engineering. The prestress type supporting steel structure comprises a first supporting plate, a first supporting block, a first movable seat, a first jacking screw, a first fixed seat, a second fixed seat, a second jacking screw, a second movable seat, a second adjustable supporting arm, a second supporting plate, a second supporting block and the like. An internal hexagonal wrench is inserted into an internal hexagonal groove in the upper side of an adjusting head, so that a movable column can push a locking gear to move downwards to be separated from a first driven gear and a second driven gear; the adjusting head can be conveniently driven by the internal hexagonal wrench to rotate to drive the supporting block I to abut against the center of the inner side of the supporting plate I and enable the supporting block II to abut against the center of the inner side of the supporting plate II, so that the operation convenience during operation is improved; the locking gear arranged in the supporting mechanism can clamp the first driven gear and the second driven gear, so that it is ensured that the first screw and the second screw cannot be loosened during supporting operation, and the reliability and stability of long-time supporting operation are improved.
本发明公开了一种基于大跨度基坑工程的预应力型支撑钢结构，包括支撑板一、支撑块一、活动座一、顶紧螺钉一、固定座一、固定座二、顶紧螺钉二、活动座二、可调支撑臂二、支撑板二和支撑块二等；本发明中将内六角扳手插入到调节头上侧的内六角凹槽中，从而能够使活动柱推动锁紧齿轮下移与从动齿轮一和从动齿轮二相分离，也就便于通过内六角扳手带动调节头旋转驱使支撑块一顶紧支撑板一内侧中央以及使支撑块二顶紧支撑板二内侧中央，进而提高了作业时候操作的便利性；本发明支撑机构中设置的锁紧齿轮，能够卡紧从动齿轮一和从动齿轮二，从而确保了支撑作业时螺杆一和螺杆二不会松动，也就提高了长时间支撑作业的可靠性和稳定性。
