The utility model discloses guaranteed that the transverse distribution between the board roof beam atress can exert the biggest effect for bridge assembled steel bar (prestressing force) concrete slab combines together with the hinge joint, and the rigidity of bridge is strengthened, forms an overall structure, has strengthened assembled concrete structure's superiority, thereby has improved driving travelling comfort and bridge durability greatly.
Description
Technical Field
The utility model relates to a bridge structures technical field especially relates to a bridge assembled reinforced concrete plate hinge joint damages maintenance reinforced structure.
Background
With the enhancement of comprehensive national power of China, the demand of traffic volume is also increased in a blowout manner. The pace of engineering construction is accelerated, and the occurrence of overloaded vehicles causes diseases of different degrees in a plurality of bridge projects. The problem that the hinge joint of a hollow slab beam is damaged by aiming at an assembly type steel bar (prestressed) concrete slab bridge of a simply supported beam bridge has attracted extensive attention.
Fabricated concrete structures were emerging and popularized more than half a century ago. Because of its outstanding advantages, it saves investment, shortens construction period, saves energy, reduces emission and protects environment. However, the connection between the prefabricated concrete structures of the bridge becomes a critical problem which restricts the durability of the bridge.
In the prior art, the design years of the fabricated reinforced (prestressed) concrete slabs are the same as the corresponding bridge years, and the connection (hinge joint) between the adjacent slabs is made of plain concrete with the same mark number as the beam, so that after the bridge is used for a period of time, the hinge joint is damaged, the overall rigidity of the upper structure of the bridge is reduced, the bridge is damaged, and the driving safety and the life safety are seriously affected.
The person skilled in the art is dedicated to solving the above technical drawbacks.
SUMMERY OF THE UTILITY MODEL
In view of the above-mentioned drawbacks of the prior art, the technical purpose of the present invention is to solve the problems mentioned in the background art.
In order to realize the technical purpose, the utility model provides a bridge assembled reinforced concrete plate hinge joint damages maintenance reinforced structure, including the plate girder, be provided with the concrete in the hinge joint between the plate girder, be provided with reinforcing bar in the roof beam in the plate girder, be provided with embedded bar in the hinge joint, reinforcing bar in the roof beam with embedded bar buckles respectively in the top of original reinforcing bar of mating formation and with newly mating formation reinforcing bar fixed connection.
Preferably, the original paving reinforcing steel bars are fixedly connected with the new paving reinforcing steel bars.
Preferably, the inside of newly-paved reinforcing bar is provided with the lower floor and paves, the top of lower floor's pavement is provided with the upper strata and paves.
Preferably, the concrete and the upper layer pavement material are both polypropylene fiber concrete; the upper layer is paved into a wearing layer.
The utility model has the advantages that:
the utility model discloses because above-mentioned structural design has guaranteed that the transverse distribution between the plate girder atress can exert the biggest effect for bridge assembled steel bar (prestressing force) concrete slab combines together with the hinge joint, and the rigidity of bridge is strengthened, forms an overall structure, has strengthened the superiority of assembled concrete structure, thereby has improved driving travelling comfort and bridge durability greatly.
Drawings
Fig. 1 is a schematic structural view of the present invention;
fig. 2 is an enlarged schematic view of a portion a in fig. 1.
In the figure: 1 plate girder, 2 hinge joints, 3 concrete, 4 internal reinforcing steel bars of roof beam, 5 pre-buried reinforcing steel bars, 6 original paving reinforcing steel bars, 7 new paving reinforcing steel bars, 8 lower-layer paving and 9 upper-layer paving.
Detailed Description
The conception, the specific structure and the technical effects of the present invention will be further described with reference to the accompanying drawings, so as to fully understand the objects, the features and the effects of the present invention.
Example (b):
as shown in fig. 1-2, a bridge assembly type reinforced concrete slab hinge joint damage maintenance reinforcing structure comprises slab beams 1, concrete 3 is arranged in hinge joints 2 between the slab beams 1, steel bars 4 in the slab beams 1 are arranged in the hinge joints 2, embedded steel bars 5 are arranged in the hinge joints 2, and the steel bars 4 in the slab beams and the embedded steel bars 5 are respectively bent above original paving steel bars 6 and fixedly connected with new paving steel bars 7.
Specifically, the original pavement steel bars 6 are kept to be fixedly connected with the new pavement steel bars 7 by 30cm in longitudinal and transverse length.
Specifically, a lower layer pavement 8 is arranged in the newly-paved reinforcing steel bar 7, the original paved reinforcing steel bar 6, the embedded reinforcing steel bar 5 and the beam inner reinforcing steel bar 4, an upper layer pavement 9 is arranged at the top of the lower layer pavement 8, and the upper layer pavement 9 is a wear layer formed by combining the high-strength binding power of the modified epoxy resin and the special aggregate.
Specifically, the concrete 3 and the lower layer pavement 8 are both made of C40 rapid hardening polypropylene fiber concrete, the fiber content is 0.9kg/m, so that the transverse distribution between the stress of the plate girder 1 can play the greatest role, the bridge fabricated steel bar (prestressed) concrete plate and the hinge joint 2 are combined together, the rigidity of the bridge is enhanced, an integral structure is formed, and the superiority of the fabricated concrete structure is enhanced.
The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the teachings of the present invention without undue experimentation. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.
