[0002] At present, the installation of steel bars for bridge pier columns mostly adopts the overturning method. In the construction process, scaffolding is an indispensable equipment. Now ordinary fastener-type steel pipe scaffolding or buckle-type scaffolding is commonly used. This type of scaffolding is in the construction process. Diagonal braces, scissor braces, and necessary reinforcement structures need to be set up in time to avoid deflection and inclination during the erection of the scaffold. At the same time, it is necessary to use butt fasteners to fix the steel pipe joints. The construction requirements are high and the process is complicated. Installation and dismantling The amount of work is also very large, especially for super-high variable-section rectangular piers with relatively large amount of steel reinforcement, and piers whose bridge sites are in valleys and rivers. very inefficient

Embodiment Construction
[0016] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. like figure 1 As shown, a bridge pier column reinforcement installation and operation frame includes two independent steel pipe frames 2, the cross section of which is U-shaped, and when combined, the U-shaped free end faces of the two steel pipe frames Surrounding the periphery of the bridge pier column 1 , the corresponding two free end surfaces are fixedly connected by the combination fastener 4 . The steel pipe frame is welded with φ57×3mm steel pipes.
[0017] The combination of the two steel pipe frame options is as follows figure 2 As shown, the combination fastener 4 includes a fastener body 42, and a combination card slot 43 is provided at the left and right ends of the fastener body 42; The two connecting cross bars 21 are respectively clipped in the combination slots 43 at the left and right ends of the same fastener body...

The invention discloses an operation frame for installation of bridge pier column steel bars. The operation frame comprises two steel pipe frames. The cross section of each steel pipe frame is in a U shape. The free end faces of the two steel pipe frames correspond to each other to surround the periphery of a bridge pier column, and the two corresponding free end faces are fixedly connected through a combined fastener. The combined fastener comprises a fastener body, wherein the left end and the right end of the fastener body are each provided with a combined clamping groove. Connecting cross rods are arranged on the free end faces of the steel pipe frames. The two connecting cross rods on the corresponding free end faces are clamped in the combined clamping grooves in the left end and the right end of the same fastener body in a sleeved mode correspondingly. The operation frame is light and simple in structure, easy to manufacture and not limited by a construction site, easy and convenient to operate in the construction process, safe and reliable and capable of being moved flexibly and used repeatedly, the bridge construction progress is accelerated, and the engineering cost is reduced.
