Description
Technical Field
The invention belongs to the technical field of bridge engineering, and particularly relates to an assembled pier beam consolidation structure.
Background
In order to relieve the traffic pressure in cities, a large number of urban viaducts are built in many cities. Constructing the urban viaduct mainly adopts a prestressed concrete cast-in-place box girder structure; along with the development of cities, the defects that the urban traffic is greatly influenced and traffic jam is easily caused during the construction of the cast-in-place box girder are more and more obvious.
The steel structure has good performance, light self weight and good durability; the steel has higher tensile strength, compression strength and shear strength, and simultaneously has good plasticity and toughness, thereby improving the shock resistance of the steel structure bridge; the steel structure is energy-saving and environment-friendly, can be recycled, has less construction waste and saves resources; the characteristics of unitization and light dead weight of steel structure manufacturing are convenient for the transportation and installation of components, and the construction period is short; the steel structure can be processed in advance in a factory, the occupied area of a construction site is small, and the construction method has higher erection speed and lower construction cost; the steel structural member is generally manufactured and processed in a factory, the industrialization degree is high, the structural defects are few, and the service life is longer. Therefore, steel structure bridges are gradually popularized and applied, and fabricated bridges, mainly consisting of steel-concrete composite girders and steel box girders, are also widely applied to the construction of urban viaducts.
The steel box girder bridge generally adopts concrete pier columns, the structural rigidity of the reinforced concrete pier columns is high, and the steel box girder bridge can be designed into shapes such as plate type piers, vase type piers, column type piers and the like according to requirements. The bottom of the pier body is generally embedded into the soil, and the concrete pier stud has stronger corrosion resistance, so the concrete pier stud is widely applied to bridge design.
The connection mode of the steel box girder and the concrete pier stud is of great importance, and the common connection mode comprises rigid connection and hinging. The bearing is hinged, so that the stress of the pier is analyzed, the pier is a common compression column, the stress is simple, and the bending moment transmitted to the pier column by the beam can be released; but the torsional constraint capacity of the hinged joint on the upper structure is poor, particularly, a curved bridge can generate larger torque, and when larger transverse load is applied, the support can be dislocated and sheared to be damaged under the action of horizontal force, even the support is in a hollow state or a beam body topples; meanwhile, the maintenance and repair cost of the support is high, and the support is troublesome to replace, so that the later-period operation cost is increased.
The steel beam 100 is rigidly connected to the reinforced concrete pier 200, so that the upper and lower portions of the bridge are integrated, the hyperstatic frequency of the bridge span structure can be increased, and the overall anti-seismic performance of the bridge structure can be improved. In the internal force distribution of the structure, the fulcrum hogging moment originally borne by the steel beam 100 alone is borne by the steel beam 100 and the reinforced concrete pier 200 together at the fulcrum of the bridge, so that the load of the steel beam 100 is reduced. By adopting the combined rigid joint form, the advantages of steel and concrete are fully utilized, and the steel consumption of the upper structure is saved. In addition, the use of the support is omitted, so that the bridge construction cost is further reduced, and the maintenance and management cost of the bridge after the bridge is formed can be reduced. The structural form is increasingly used in bridge construction because of the above-mentioned advantages of rigidly coupling the steel girder 100 with the reinforced concrete pier 200.
The traditional steel beam 100 and the reinforced concrete pier 200 are rigidly connected in the following mode: reinforced concrete, prestressed reinforced concrete, and shear key connection developed in recent years.
The prestressed reinforced concrete connection mode overcomes the defect that the reinforced concrete connection mode is easy to generate cracks, but the structural arrangement and the construction are difficult. And the shear force key connection mode of the design method for limiting the crack width is adopted, so that the construction performance is improved. Therefore, in recent years, shear connection is mainly used to rigidly connect the steel beam 100 and the reinforced concrete pier 200.
The traditional shear connection structure form of the steel beam and the reinforced concrete pier mainly depends on the stud type shear connector 300 to transmit the force between steel and concrete. However, in the case of the steel-concrete composite girder or the steel box girder, if the stud shear key 300 is used, the main reinforcing bars 201 of the reinforced concrete pier 200 must pass through the lower flange or the bottom plate of the steel girder 100, so that the construction accuracy of the prefabricated holes of the reinforcing bars and the steel beam lower flange of the reinforced concrete bridge is required to be high, and a large number of studs must be welded to the cross beam, which causes many problems in construction and construction. In addition, extending the main reinforcement 201 of the concrete pier 200 into the steel girder structure welded with the shear key 300 requires that the lower flange plate of the steel girder transmit the pressure to the top of the pier body in the form of the supporting pressing plate 101, or the steel column 102 is provided at the connection portion for the purpose of transmitting the pressure. The specific structural form can be seen in fig. 1-3. The currently common structural form of the rigid node generally has the following problems:
(1) after the main reinforcing bars 201 in the pier 200 are extended to the top of the girder, secondary pouring of concrete is required, which affects the construction period.
(2) The steel joint has many internal members, complex structure, is not beneficial to construction and is difficult to ensure the quality of poured concrete.
(3) The bonding length of the main reinforcing steel bar 201 of the pier at the rigid joint part is limited by the height of the steel beam.
