Abstract
The utility model discloses a prestressing force letter bridge floor hogging moment slip casting device, including pre-buried reservation bellows in the bridge floor, reserve the bellows and reserve continuous end position in advance, insert pre-buried slip casting pipe in the reservation bellows of bridge floor continuous end department wherein one side, insert pre-buried blast pipe in the reservation bellows of opposite side, the upper end of two adjacent reservation bellows is passed through the continuous section bellows and is connected, and the tip of pre-buried slip casting pipe and pre-buried blast pipe stretches out from the continuous section bellows respectively and the bellows junction between the reservation bellows. Adopt the utility model discloses afterwards, the operation personnel alright through pre-buried slip casting pipe to bridge floor hogging moment slip casting on the bridge floor, the gas alright follow pre-buried blast pipe discharge that the slip casting in-process produced. Therefore, the operator does not need to use the hanging basket to carry out grouting construction under the bridge floor, and the potential safety hazard of the operator in the grouting process is reduced.
Description
Technical Field
The utility model relates to a prestressing force letter bridge floor hogging moment slip casting device belongs to letter bridge floor prestressing force construction technical field.
Background
At present, the negative moment grouting construction of the bridge deck of the existing prestressed T-beam simply-supported beam bridge mainly adopts a worker to cooperate with a bridge deck grouting machine to perform construction grouting at the negative moment position under a T-beam wing plate through a hanging basket, and the construction mode has the following defects:
1. in the prior art, a worker carries out construction under a bridge floor through a hanging basket, so that huge potential safety hazards exist to the worker;
2. bridge floor wet joint reinforcement and concrete placement just can carry out among the prior art bridge floor expansion joint slip casting and accomplish the back, influence bridge floor construction period.
SUMMERY OF THE UTILITY MODEL
The utility model provides a not enough to prior art, the utility model provides a prestressing force simple beam bridge floor hogging moment slip casting device, the device possess reduce operation personnel potential safety hazard, the later stage inspection of being convenient for, advantage such as reduction of erection time, have solved current bridge floor hogging moment slip casting construction safety, bridge floor construction period's problem.
The technical scheme of the utility model is realized like this: the utility model provides a prestressing force simply supported girder bridge floor hogging moment slip casting device, includes the pre-buried bellows that reserves in the bridge floor, the upper end of reserving the bellows stretches out from the bridge floor expansion joint, and its lower extreme stretches out from the bridge floor hogging moment, and it has pre-buried slip casting pipe to insert in the reservation bellows of one side wherein of bridge floor expansion joint department, has inserted pre-buried blast pipe in the reservation bellows of opposite side, and the upper end of two adjacent reservation bellows is passed through the continuous section bellows and is connected, and the tip of pre-buried slip casting pipe and pre-buried blast pipe stretches out from the continuous section bellows respectively and the bellows junction between the reservation bellows.
Further, the both ends of continuous section bellows are connected with the bellows connector, the bellows connector cover is in the upper end of reserving the bellows, has all seted up the triangular groove in the tip of bellows connector and the upper end of reserving the bellows, and pre-buried slip casting pipe or pre-buried blast pipe are stretched out from the triangular groove.
Further, the embedded grouting pipe and the embedded exhaust pipe extend out of the corrugated pipe from the connecting position of the corrugated pipe by 20-50 cm.
Since the technical scheme is used, the utility model has the advantages that:
1. adopt the utility model discloses afterwards, the operation personnel alright through pre-buried slip casting pipe to bridge floor hogging moment slip casting on the bridge floor, the gas alright follow pre-buried blast pipe discharge that the slip casting in-process produced. Therefore, the operator does not need to use the hanging basket to carry out grouting construction under the bridge floor, and the potential safety hazard of the operator in the grouting process is reduced.
2. The construction of the wet joint of the bridge deck is not required to be carried out after grouting is finished, and the construction period of the bridge deck is shortened.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The embodiment of the utility model provides a: referring to fig. 1-4, a prestressing force simply supported girder bridge floor hogging moment slip casting device, including pre-buried reservation bellows 2 in the bridge floor, the upper end of reservation bellows 2 stretches out from bridge floor continuous end department, has pre-buried slip casting pipe 3 in the reservation bellows 2 of one side wherein of the bridge floor, has pre-buried blast pipe 6 in the reservation bellows 2 of opposite side, and the upper end of two adjacent reservation bellows 2 is connected through continuous section bellows 5, and the tip of pre-buried slip casting pipe 3 and pre-buried blast pipe 6 stretches out from continuous section bellows 5 and the bellows junction 4 between the reservation bellows 2 respectively. The both ends of continuous section bellows 5 are connected with bellows connector 1, bellows connector 1 cover is in the upper end of reserving bellows 2, has all seted up the triangular groove in the tip of bellows connector 1 and the upper end of reserving bellows 2, and pre-buried slip casting pipe 3 or pre-buried blast pipe 6 are followed the triangular groove and are stretched out. The embedded grouting pipe 3 and the embedded exhaust pipe 6 extend out of the corrugated pipe joint 4 by 20-50 cm respectively.
During construction, the reserved corrugated pipes 2 are pre-buried in the bridge deck, the upper ends of the reserved corrugated pipes 2 are arranged at the continuous end of the bridge deck, then the upper ends of two adjacent reserved corrugated pipes 2 are connected through the continuous section corrugated pipes 5 at the continuous end of the bridge deck, the pre-buried grouting pipes 3 and the pre-buried exhaust pipes 6 are inserted into the reserved corrugated pipes 2 from triangular grooves on two sides respectively until the lower ends of the pre-buried grouting pipes 3 and the pre-buried exhaust pipes 6 extend out of the continuous end of the bridge deck, the upper ends of the pre-buried grouting pipes 3 and the pre-buried exhaust pipes 6 extend out of the corrugated pipes from the corrugated pipe joints 4 by 20-50 cm respectively, and therefore an operator can perform grouting on the bridge deck through the pre-buried grouting pipes 3 to the negative bending moment of the bridge deck, and gas generated in the grouting process. Therefore, the operator does not need to use the hanging basket to carry out grouting construction under the bridge floor, and the potential safety hazard of the operator in the grouting process is reduced; meanwhile, the construction of the wet joint of the bridge deck is not performed after grouting is finished, and the construction period of the bridge deck is shortened.
