Description

Technical Field

[0001] The present invention belongs to the technical field of bridge engineering, and particularly relates to an assembled pier-beam consolidation structure. Background Art

[0002] In order to relieve the traffic pressure within cities, a large number of urban viaducts have been built in many cities. The construction of urban viaducts mainly adopts the prestressed concrete cast-in-place box girder structure; with the development of cities, the impact of cast-in-place box girder construction on urban traffic is significant during the construction period, and the drawback of being prone to traffic jams has become increasingly obvious.

[0003] The steel structure itself has good performance, with a relatively light self-weight and good durability; the tensile, compressive, and shear strengths of steel are relatively high, and at the same time, steel has good plasticity and toughness, thereby improving the seismic resistance of steel structure bridges; the steel structure is energy-saving and environmentally friendly, can be recycled, generates less construction waste, and saves resources; the characteristics of unitization in the manufacture of steel structures and their light self-weight facilitate the transportation and installation of components, with a short construction period; the steel structure can be prefabricated in the factory in advance, occupying a small area at the construction site, having a faster erection speed and lower construction cost; steel structure components are generally manufactured and processed in the factory, with a relatively high degree of industrialization, fewer structural defects, and a longer service life. Therefore, steel structure bridges have been gradually promoted and applied, and assembled bridges mainly composed of steel-concrete composite beams and steel box girders have also been widely used in the construction of urban viaducts.

[0004] Steel box girder bridges generally adopt concrete piers. Reinforced concrete pier structures have large stiffness and can be designed into various shapes such as slab piers, vase-shaped piers, and column piers according to needs. The bottom of the pier body is generally buried in the soil, and concrete piers also have strong corrosion resistance, so they are widely used in bridge design.

[0005] The connection method between the steel box girder and the concrete pier is crucial. The commonly used connection forms are rigid connection and hinged connection. When using a bearing hinge connection, from the analysis of the force on the bridge pier, the bridge pier is a general compression column with simple force, and the moment transmitted from the beam to the pier can be released; however, the hinged connection has poor anti-torsion restraint ability for the superstructure. Especially for curved bridges, large torques will be generated. When there is a large lateral load, the bearings may be misaligned and shear damaged under the action of horizontal forces, or even the bearings may become disengaged or the beam body may overturn; at the same time, the maintenance and repair costs of the bearings are high, and the replacement is troublesome, thus increasing the later operation cost.

[0006] The steel beam 100 is rigidly connected to the reinforced concrete pier 200, making the upper and lower structures of the bridge an integral whole. This can increase the degree of redundancy of the bridge span structure and improve the overall seismic performance of the bridge structure. In terms of the internal force distribution of the structure, at the fulcrum of the bridge, the negative moment at the fulcrum originally borne solely by the steel beam 100 is now jointly borne by the steel beam 100 and the reinforced concrete pier 200, thus reducing the burden on the steel beam 100. By adopting such a combined rigid joint form, the respective advantages of steel and concrete are fully utilized, and the steel consumption of the upper structure is saved. In addition, since the use of bearings is eliminated, the construction cost of the bridge is further reduced, and the maintenance and management costs after the bridge is completed can also be reduced. It is precisely because of the above advantages of rigidly connecting the steel beam 100 and the reinforced concrete pier 200 that this structural form has been increasingly applied in bridge engineering.

[0007] Traditional rigid connection methods between the steel beam 100 and the reinforced concrete pier 200 include: reinforced concrete method, prestressed reinforced concrete method, and the shear key connection method developed in recent years.

[0008] The prestressed reinforced concrete connection method overcomes the weakness of the reinforced concrete connection method that is prone to cracking, but the structural layout and construction are relatively difficult. The shear key connection method using the crack width limitation design method has improved the constructability. Therefore, the shear key connection has become the main method for the rigid connection between the steel beam 100 and the reinforced concrete pier 200 in recent years.

[0009] The traditional shear key connection structural form between the steel beam and the reinforced concrete pier mainly relies on the stud shear key 300 to transfer the force between the steel and concrete. However, for a steel-concrete composite beam or a steel box girder, if the stud shear key 300 is used, the main reinforcement 201 of the reinforced concrete pier 200 must pass through the lower flange or bottom plate of the steel main beam 100. Therefore, the construction accuracy requirements for the prefabricated holes of the reinforcement on the reinforced concrete bridge and the lower flange of the steel beam are very high, and a large number of studs need to be welded on the cross beam. These all pose many problems in terms of structure and construction. In addition, to extend the main reinforcement 201 in the concrete pier 200 into the steel beam structure welded with the shear key 300, it is necessary to transfer the pressure from the lower flange plate of the steel beam in the form of a supporting pressure plate 101 to the top of the pier body, or to set a steel column 102 at the connection part to achieve the purpose of force transmission. The specific structural form can be seen in Figures 1 to 3 . Currently, the commonly used rigid joint structural forms generally have the following problems:

[0010] (1) After extending the main reinforcement 201 in the pier 200 to the top of the beam, secondary concrete pouring is required, which affects the construction period.

[0011] (2) There are many components inside the rigid joint, and the structure is complex, which is not conducive to construction and it is difficult to ensure the quality of the poured concrete.

[0012] (3) The bonding length of the main reinforcement bars 201 of the rigid joint pier is limited by the height of the steel girder. Summary of the Invention

[0039] Among them, the plate surface of the beam bottom consolidation base plate 111 is parallel to the plate surface of the box bottom plate of the main beam 1. As shown in Figures 4 to 7 , there is a certain distance between the beam bottom consolidation base plate 111 and the box bottom plate, that is, the beam bottom consolidation base plate 111 is installed on the box bottom plate through a transfer structure, and the transfer structure needs to meet the force transfer requirements; in one embodiment, as shown in Figures 4 to 7, the base 11 of the beam bottom connection frame further includes a plurality of second stiffeners 112 arranged vertically and horizontally.

On the one hand, the pier inner anchor plate 23 can improve the cooperative stress performance of the respective anchor steel bars 21 and can evenly transmit the forces received by the respective anchor steel bars 21 to the pier body. On the other hand, it can effectively enhance the anchoring structural stability and working reliability of the respective anchor steel bars 21 in the pier 2 and prevent the anchor steel bars 21 from being pulled out of the pier 2.

[0043] Through the setting of this steel structure force transmission bracket system, the fixed connection between the steel beam 1 and the reinforced concrete pier 2 is realized, and the overall consolidation structure has relatively strong vertical connection stiffness and horizontal connection stiffness; when the pier-beam consolidation force transmission bracket 3 adopts a stiffening rib as the force transmission structure, on the basis of realizing vertical force transmission, it can prevent a large horizontal force from being transmitted to the pier 2 and causing damage to the pier 2. The force transmission path of this pier-beam consolidation structure is clear, the processing is convenient, it is convenient for the transportation and installation of components, the assembly is simple, the on-site assembly is convenient, and the construction period is short.

[0044] As described above, sealed concrete 4 is poured into the pier-beam consolidation force transmission bracket 3.

[0045] The construction process of the above-mentioned assembled pier-beam consolidation structure is generally as follows:
