AI Technical Summary

Problems solved by technology

When the pier height is low (such as below 10m), the design of the foundation is difficult, and the investment increases greatly. Bridge piers are basically unusable

Embodiment Construction

[0011] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0012] refer to figure 2 , the rigid frame-continuous bridge pier structure of the present invention includes a cover beam 10 and at least two pier columns arranged at intervals along its longitudinal direction, and a consolidated pier column whose top end is consolidated with the cover beam 10 is included in the pier column 20. The rest of the piers are hinged piers 21 whose top ends are hinged with the cover beam 10 through the movable support 22. The setting of the movable support 22 allows the cover beam 10 to rotate and move during deflection and stretching. The force of each pier column is simple and clear, which is convenient for the foundation design when the pier height is low, which can save a lot of foundation investment, and can be segmented Separate pouring can flexibly meet the needs of various construction conditions.

Abstract

The invention discloses a rigid frame-continuous bridge pier structure, which aims to reduce the difficulty of foundation design and greatly save foundation investment, can be separately cast section by section, and can flexibly meet the requirements of various construction conditions. The structure comprises a bent cap (10) and at least two pier columns which are arranged at intervals along the longitudinal direction of the bent cap. The structure is characterized in that the pier columns comprise a fixedly-connected pier column (20), the top end of which forms fixed connection with the bentcap (10); and the rest pier columns are hinged pier columns (21), the top ends of which form hinge joint with the bent cap (10) through movable supports (22). The structure is particularly suitable for a bearing structure of a combined facility of an overhead railway station bridge and a building or pier columns of a multi-track bridge.

Description

technical field [0001] The invention relates to a supporting structure of a bridge or a building, in particular to a supporting structure of a railway elevated station bridge (bridge) building (building) integrated facility or a pier of a multi-line bridge. Background technique [0002] At present, the supporting structures of railway multi-line bridges and elevated station bridge construction integration facilities mainly adopt bridge rigid frame piers. Rigid frame piers of bridges are mainly composed of cover beams and pier columns arranged at intervals along its longitudinal direction, and the upper ends of each pier column are consolidated with cover beams to form a statically indeterminate structure. Under the action of vertical load, in addition to bearing the pressure, the pier column also bears the bending moment, which will generate horizontal thrust, so it is necessary to have good foundation conditions, or use a deeper foundation and special construction measures ...
