Technical Field
The utility model relates to a bridge construction technical field, especially a cast in situ continuous 0# piece bracket pre-compaction device of roof beam.
Background
In the past, the continuous cast-in-place beam 0# block is generally constructed by using a bracket, and the bracket needs to be pre-pressed before casting in order to ensure the safety and stability of the bracket. In the prior art, the prepressing method of the bracket generally comprises the following steps: firstly, under the condition that the pier is not high, a positive-pressure prepressing method is adopted, namely prepressing objects are directly put on a bracket for prepressing, and most of the prepressing objects are sandbags, water tanks or precast blocks and the like. When constructing in the higher places of pier studs such as mountain canyons, the pre-buried finish rolling screw-thread steel of pier is adopted as the anchoring end, then the steel strand wires are utilized to connect the bracket and the anchoring end, the bracket is provided with a hydraulic jack to perform reverse pulling operation, and the bracket prepressing is completed. For the construction in the higher places of pier stud such as mountain area canyon, because 0# piece dead weight is big, consider other loads such as template, the required power of exerting is great, utilizes the steel strand wires to carry out the risk that the back-pull has the steel wire fracture, and the potential safety hazard is high. Meanwhile, the steel strand consumed by tensioning is basically waste after the tensioning, so that great material loss and cost investment are caused.
SUMMERY OF THE UTILITY MODEL
Aiming at the problems, the utility model provides a 0# piece bracket pre-compaction device of cast-in-place continuous beam, solves when the higher place of pier stud is under construction, and bracket pre-compaction potential safety hazard is high, with large costs problem.
In order to achieve the above purpose, the utility model adopts the technical proposal that: the utility model provides a cast-in-place continuous beam 0# piece bracket pre-compaction device, includes pre-buried pole, pre-compaction board and jack, the pre-compaction board is fixed in on the pre-buried pole, the lower extreme of pre-buried pole is fixed in the pier, the jack is located between bracket and the pre-compaction board, the upper end butt of jack in the pre-compaction board, the lower extreme butt of jack in the bracket.
Furthermore, the pre-embedded rod is made of finish-rolled deformed steel bars, and the middle part of the pre-pressing plate is fixed on the pre-embedded rod through nuts. The finish-rolled deformed steel bar has high hardness, and the prepressing plate is fixed by using the nut conveniently and is convenient to disassemble.
Furthermore, the prepressing plate is connected with a reinforcing rod, one end of the reinforcing rod is fixed at one end of the prepressing plate, and the other end of the reinforcing rod is fixed at the upper end of the embedded rod. The reinforcing rod is connected with the prepressing plate and the embedded rod, so that the prepressing plate, the reinforcing rod and the embedded rod are surrounded into a triangular structure, the triangular structure is good in stability, and can bear larger acting force and meet the load applied by the jack.
Furthermore, the number of the reinforcing rods is two, and the two reinforcing rods are symmetrically arranged.
Furthermore, a vertical support rod is arranged between the middle part of the reinforcing rod and the prepressing plate, the upper end of the support rod is fixed on the reinforcing rod, and the lower end of the support rod is fixed on the prepressing plate. The support rod further enhances the connection stability between the reinforcing rod and the prepressing plate, so that the prepressing plate can bear larger acting force.
Furthermore, two jacks are arranged and are respectively arranged below two ends of the prepressing plate. Two jacks pre-press the both ends of bracket respectively for the pre-compaction effect of bracket is better, ensures that the bracket is safer and more stable.
Due to the adoption of the technical scheme, the beneficial effects of the utility model are that:
the utility model discloses a 0# piece bracket pre-compaction device of continuous roof beam of cast in situ includes pre-buried pole, pre-pressing board and jack, and when the jack rose, the upper end of jack withstood the pre-pressing board, because on the pre-pressing board was fixed in pre-buried pole, on pre-buried pole was fixed in the pier, the pre-pressing board can't be by jack-up, so the jack bore the reaction force of pre-pressing board, and the lower extreme of jack is pushed down the bracket and is applyed the effort to the bracket, accomplishes the pre-compaction work of bracket. The utility model discloses a 0# piece bracket pre-compaction device of continuous roof beam of cast in situ need not to adopt steel strand wires to anti-the pre-compaction of drawing of bracket, so do not have the cracked risk of steel strand wires, and the security is high, and the pre-compaction board can repetitious usage moreover, and the cost drops into lowly.
