[0035] The cap beam a is located at the top of the pier or abutment, and is used to support, distribute and transfer the load of the superstructure. It is usually designed in the form of a crossbeam. The bracket described in the present application is composed of at least two bracket units 1, which are respectively arranged at any protrusions at both ends of the cap beam. The two ends of the safety mother rope b are fixed on the two bracket units 1. The specific setting position can be adjusted according to the working range of the on-site construction personnel; a single bracket unit 1 includes at least two legs 11, which are respectively located on both sides of the protrusion of the cap beam a. Preferably, two legs 11 on one side are more stable. The adjustment unit 2 is arranged on the leg 11 on the opposite side of the bracket unit 1; the adjustment rod 21 is set as a threaded rod, which is threadedly connected to the threaded hole A12 on the leg 11. The position of the adjustment rod 21 relative to the leg 11 is changed by rotating the adjustment rod 21, thereby changing the distance of the clamping plate 22 arranged on the end of the adjustment rod 21 close to the cap beam a relative to the cap beam a. When the clamping plate 22 is adjusted to stop on the surface of the cap beam a, the bracket is fixed on the cap beam a.

[0036] The adjusting unit 2 further includes a handle 23 disposed on an end of the adjusting rod 21 away from the pressing plate 22 .

[0037] In this embodiment, in order to further facilitate manual operation, a handle 23 is provided on the end of the adjusting rod 21 away from the clamping plate 22. The shape of the handle 23 can be a horizontal bar, a butterfly shape, or other shapes that are easy to operate.
