The utility model discloses the construction risk is low, and the pre-compaction load loading is accurate.

Description

0# piece high mound bracket pre-compaction structure

Technical Field

The utility model belongs to the technical field of the high mound construction of bridge, a structure that carries out the pre-compaction to the bracket when adopting the bracket to carry out the higher 0# piece construction of pier shaft is related to.

Background

In the construction of a continuous beam bridge, a 0# block with a high pier body is generally constructed by adopting a bracket. The bracket all needs the pre-compaction before 0# piece concrete placement to eliminate the inelastic deformation of bracket, improve the security of bracket. The method comprises the steps of hoisting the pre-pressed load onto the bracket by using a crane, hoisting the pre-pressed load off the bracket after pre-pressing is finished, and hoisting the stacked load off the bracket, so that the process is complicated, the consumed time is long, the cost is high, and for high-pier brackets, the high-altitude hoisting can increase the construction risk; in addition, to the bracket that only sets up in pier shaft one side, pile and carry the pre-compaction in-process and can lead to pier shaft both sides atress unbalanced, cause harmful effects to the pier shaft structure.

Disclosure of Invention

The utility model aims at providing a carry out not enough that the bracket pre-compaction exists to current heap year method, provide a structure that carries out the bracket pre-compaction with the help of reaction frame, reduce construction risk and cost.

The technical scheme of the utility model as follows:

the utility model provides a 0# piece high mound bracket pre-compaction structure, the bracket is installed in pier shaft one side, its characterized in that: 3 brackets are arranged on the other side of the pier body opposite to the bracket at equal intervals along the transverse direction of the pier body, 3 Bailey beams are arranged at the top of the pier body, one end of each Bailey beam extends to the position above each bracket, and the other end of each Bailey beam extends to the position above the bracket; two rows of anchoring rods are transversely arranged at the top of the pier body along the pier body, the lower end of each anchoring rod is anchored in the concrete of the pier body, two rows of anchoring rods, which are opposite to the bracket and the pier top, at the top of the Bailey beam are respectively provided with a shoulder-pole beam, and the upper end of each anchoring rod penetrates through the shoulder-pole beam at the top of the Bailey beam opposite to the upper end of each anchoring rod and is in threaded connection with a fixing nut; each bracket and the shoulder pole beam at the top of the Bailey beam opposite to the bracket are oppositely pulled through two pull rods; two jacks are arranged on the bracket and are opposite to the bottom of each Bailey beam.

Compared with the conventional preloading method, the utility model mainly has the following advantages:

(1) the operation process is simple, the construction speed is high, and the cost is low;

(2) the overhead hoisting operation is reduced, and the construction risk is reduced;

(3) the stress on the two sides of the pier body is balanced, which is beneficial to protecting the pier body structure.

fig. 3 is a side view of the utility model on one side of the bracket.

Detailed Description

As shown in fig. 1, 2 and 3, a 0# construction bracket 1 is installed on one side of a

pier body

2, 3 corbels 3 are arranged on the other side of the pier body 2 opposite to the bracket 1 at equal intervals along the transverse direction of the pier body, 3 bailey beams 4 are arranged at the top of the pier body, one end of each bailey beam 4 extends to the upper part of each corbel 3, and the other end of each bailey beam 4 extends to the upper part of the bracket 1; two rows of anchoring rods 5 are transversely arranged at the top of the pier body 2 along the pier body, the lower end of each anchoring rod 5 is anchored in concrete of the pier body 2, two rows of anchoring rods, which are opposite to the corbels and the pier top, at the top of the bailey beam 4 are respectively provided with a shoulder pole beam 6, and the upper end of each anchoring rod 5 penetrates through the shoulder pole beam 6 at the top of the bailey beam opposite to the upper end of the anchoring rod 5 and is in threaded connection with a fixing nut; each bracket 3 and a shoulder pole beam 6 at the top of the Bailey beam 4 opposite to the bracket are oppositely pulled through two pull rods 7; two jacks 8 are arranged on the bracket 1 and right opposite to the bottom of each Bailey beam 4.
