Detailed Description

As shown in fig. 1, 2 and 3, the utility model discloses a pin rod 2 is arranged on each pier 1 and runs through the pier along the bridge direction, a box-type bracket 3 is respectively inserted at both ends of the pin rod 2, an unloading device 4 is welded at the top of the box-type bracket 3, the upper end of a vertically arranged connecting plate 5 is welded at one side of the box-type bracket facing the pier, and a hanging basket 6 is welded at the lower end of the connecting plate 5; the transverse bridge is provided with bearing beams 7 on the unloading devices on the same side of the bridge pier, and the bearing beams on the two sides of the bridge pier are connected through a tie rod 8; and a plurality of distribution beams 9 are erected on the bearing beam along the bridge direction, and a bent cap template bottom plate 10 is installed on the distribution beams.

As shown in fig. 4, the unloading device 4 is a butt steel wedge unloading frame, which is an existing support unloading device and includes two wedge blocks 41, the inclined surfaces of the two wedge blocks are opposite and connected through a transverse pull rod 42, two ends of the pull rod are screwed with adjusting nuts 43, and the bottom surface of one wedge block 41 is welded with the top surface of the box bracket 3.

The hanging basket 6 comprises a rectangular bottom frame welded by angle steel, 4 vertical rods 61 are welded at four corners of the bottom frame, adjacent vertical rods are connected through cross rods 62, and a plurality of reinforcing steel bars 63 are welded on the bottom frame at equal intervals and serve as a platform for supporting constructors to stand; the connecting plate 5 and the hanging basket 6 are welded with the connecting rod towards the bottom frame edge of one side of the pier stud.

Opposite through pin holes are formed in two opposite sides of the box-type bracket 4, penetrate through connecting plates welded with the bracket and penetrate through the pin holes on the pin rods 2.

The utility model discloses first weld box bracket 3 with unload device 4 and hang basket 6 on ground, as shown in figure 4. When the bracket is installed, the bracket is integrally lifted by a crane and is inserted on the pin rod, and constructors perform operations of adjusting the height of the unloading device, assisting in installing the bearing beam, the distribution beam and the cover beam template and the like in the hanging basket 6; after construction is completed, adjusting nuts at two ends of a pull rod of the unloading device are loosened, the height of the unloading device is reduced, the form is removed and the bracket is detached, and finally the box-type bracket and the unloading frame are integrally hung to the ground by using a crane.
