Description
Technical Field
The utility model belongs to the technical field of bridge engineering, especially, relate to a vertical prestressed reinforcement bellows protection device.
Background
When a bridge is constructed across a large valley and a large river, the bridge is generally designed to be a prestressed structural bridge, and the prestressed engineering quality control is the most important part in the construction of the prestressed structural bridge. The bellows installation back end department lug connection anchor backing plate in the vertical prestressing force construction of present stage, because of the bellows generally is the plastics material, can't be effectively connected with the anchor backing plate, in being destroyed easily and concrete grout enters into the bellows easily in the concrete construction in the construction, the unable assurance characteristics of quality, the great reduction of efficiency of construction simultaneously.
SUMMERY OF THE UTILITY MODEL
The utility model provides a vertical prestressing tendons bellows protection device, aim at avoid the bellows end to be destroyed, and concrete thick liquid gets into in the bellows when preventing concrete placement simultaneously.
In order to achieve the above purpose, the utility model adopts the technical scheme that:
a vertical prestressed rib corrugated pipe protection device comprises a protection device, wherein the protection device comprises an anchor backing plate and a protection pipe vertically connected with the anchor backing plate, the protection pipe is of a round pipe type structure, a preformed hole is formed in the position, located on the protection pipe, of the anchor backing plate and with the protection pipe as the circle center, and the diameter of the preformed hole is smaller than that of the protection pipe;
the protection device further comprises finish-rolled deformed steel bar, one end of the finish-rolled deformed steel bar is located in the protection pipe after penetrating through the preformed hole, the other end of the finish-rolled deformed steel bar, which does not penetrate through the preformed hole, enables the finish-rolled deformed steel bar to be fixed on the anchor backing plate through the nut, the corrugated pipe is arranged between the outer wall of the finish-rolled deformed steel bar and the inner wall of the protection pipe, and the corrugated pipe is sleeved outside the finish-rolled deformed steel bar and the end of the corrugated pipe abuts against the anchor backing plate.
Furthermore, the anchor backing plate is connected with the protection pipe in a welding mode.
Further, the length of the corrugated tube is greater than the length of the protection tube.
Further, the length of the corrugated pipe is smaller than that of the finish-rolled deformed steel bar.
Compared with the prior art, the utility model discloses following beneficial effect has:
the utility model comprises a protection device, the protection device comprises an anchor backing plate and a protection tube vertically connected with the anchor backing plate, the protection tube is of a round tube type structure, a preformed hole is arranged at the position of the anchor backing plate on the protection tube by taking the protection tube as the center of a circle, and the diameter of the preformed hole is smaller than that of the protection tube; the protection device further comprises finish-rolled deformed steel bar, one end of the finish-rolled deformed steel bar is located in the protection pipe after penetrating through the preformed hole, the other end of the finish-rolled deformed steel bar, which does not penetrate through the preformed hole, enables the finish-rolled deformed steel bar to be fixed on the anchor backing plate through the nut, the corrugated pipe is arranged between the outer wall of the finish-rolled deformed steel bar and the inner wall of the protection pipe, and the corrugated pipe is sleeved outside the finish-rolled deformed steel bar and the end of the corrugated pipe abuts against the anchor backing plate. The finish rolling deformed steel bar of the protection device penetrates through the corrugated pipe and is fixed through the nut, the damage caused by the connection of the end of the corrugated pipe and the anchor backing plate is avoided, and when concrete is poured, concrete grout enters the corrugated pipe to cause unnecessary pipe blockage and grout pressing quality reduction. Manpower and material resources are greatly reduced, the practicability of the protection device is effectively improved, the construction efficiency is improved, and the construction quality is guaranteed.
