The construction period of a single pier body is long, and the turnover speed of the pier body platform support and the template is low. 3. The vertical butt joint degree of difficulty of owner muscle is great, and is difficult to guarantee the muffjoint department installation quality. The thickness of the concrete protective layer is difficult to ensure. 4. The process of the scattered assembly belongs to high-altitude operation, and the safety risk is high.
In addition, pier shaft reinforcing bar adopts the prefabricated hoist and mount of branch face, subsection in the current bridge work progress, mainly has following several: 1. and a small positioning clamping groove is manufactured, and the single-side main reinforcement prefabrication hoisting is realized. 2. And manufacturing a small jig frame, and realizing segmental prefabrication and hoisting of stirrups. But the integral prefabrication and hoisting of the large pier body reinforcing steel bars cannot be realized.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model provides a bed-jig structure of whole prefabricated hoist and mount of large-scale pier shaft reinforcing bar has realized the whole prefabricated hoist and mount of large-scale pier shaft reinforcing bar to make the whole prefabricated hoist and mount more high-efficient, more swift, more convenient.
The utility model provides an adopted technical scheme of its technical problem does: a jig frame for integral prefabrication and hoisting of large pier body reinforcing steel bars comprises a main frame consisting of square steel, wherein cross bars and a plurality of reinforcing bars are arranged on the front side surface, the rear side surface, the left side surface and the right side surface of the main frame respectively, the cross bars are arranged in the middle of the front side surface, the rear side surface, the left side surface and the right side surface of the main frame, and the reinforcing bars are arranged between the main frame and the cross bars and form a rhombus; the top and the bottom of the main frame are respectively provided with a plurality of steel clamping pieces, and a plurality of clamping grooves for clamping steel bars are uniformly arranged on each steel clamping piece at intervals.
Furthermore, a cross-shaped connecting rod is arranged in the middle of the top of the main frame, and a lifting hook is arranged in the center of the connecting rod.
The utility model also discloses a pier shaft reinforcing bar construction method utilizes the bed-jig of foretell whole prefabricated hoist and mount of large-scale pier shaft reinforcing bar, transversely places the main frame earlier, then is in with the semi-manufactured goods of pier shaft reinforcing bar fixed on the steel clip, the ligature shaping adopts the crane to lift again and hangs messenger's bed-jig and stick up, and the crane hoists pier shaft reinforcing bar and fixes a position the installation to the mounted position, sets up the cable wind rope after the installation finishes and guarantees that pier shaft reinforcing bar is firm, do not empty.
The utility model has the advantages that:
1. realizes the standardization and prefabrication of the large pier body steel bar construction.
2. Pier shaft reinforcement can construct with the cushion cap synchronization, shortens single pier construction cycle for the turnover speed of pier shaft platform support and template reduces the input cost.
3. Convert high altitude construction into ground operation, reduced the safety risk.
4. The construction difficulty is reduced, and the installation precision of the steel bars is guaranteed.
5. The jig frame is simple in structure, easy to manufacture and high in repeated utilization rate.
