Example Embodiment

[0017] The connection structure of the present invention is mainly composed of an inverted T-shaped steel beam with a perforated web 1, rivets 2, a rivet rib with a nut 3, a triangular support steel plate 4, a steel pipe cover plate 5, a concrete cover beam 6, and a steel pipe concrete pier column 7 composition. The main features are as follows: First, the rivets 2 are welded on the webs and flanges with holes to ensure effective connection between the concrete cover beam 6 and the inverted T-shaped steel beam 1. The hole arrangement and rivet arrangement are determined according to the specific bearing capacity requirements. The second is that the steel tube cover plate 5 is welded with the concrete-filled steel tube pier column 7, and the steel tube cover plate 5 is bolted to the flange of the inverted T-shaped steel beam 1 through the rivet bar with a nut 3, and the rivet bar extends into the concrete of the concrete-filled steel tube pier column 7 In the concrete cap beam 6...

Abstract

The invention discloses a connection structure for a concrete-filled circular steel tubular pier column and a concrete cover beam. The connection structure comprises a reverse T-shaped steel beam, the concrete cover beam and the concrete-filled circular steel tubular pier column, wherein the reverse T-shaped steel beam is pre-buried at the lower end of the concrete cover beam. The connection structure is characterized by also comprising a steel tubular cover plate and a riveting rib with a nut, wherein the steel tubular cover plate is welded with the upper end of the concrete-filled circular steel tubular pier column; the hole on the web plate of the reverse T-shaped steel beam is connected with the concrete; a flange plate of the T-shaped steel beam is fixedly connected with the steel tubular cover plate through the riveting rib with the nut; and the two ends of the riveting rib with the nut are embedded in the concrete cover beam and the concrete-filled circular steel tubular pier column. The connection structure needs no complex arrangement of reinforcement, and each component can be processed in the factory and assembled on site. Only welding of a triangular supporting steel plate and the steel tubular cover plate is needed on site so as to ensure small workload and definite force transferring path. The connection structure has the advantages of simple and quick construction during the implementation.

Description

technical field [0001] The invention relates to the connection of pier structures in bridge engineering, in particular to the connection of circular steel tube concrete pier columns and concrete cover beams. Background technique [0002] Concrete bridge piers have a large cross-sectional area and require a large amount of road space, which cannot meet the increasingly busy urban traffic needs. However, the amount of steel used for steel bridge piers is too large, and the cost is high. Combining the respective advantages of steel and concrete, CFST is an ideal bridge pier structure with small cross-sectional area, low cost, high bearing capacity, good ductility, and construction without formwork. Concrete filled steel tubes are used for the pier columns of urban bridges, and reinforced concrete is still used for the bridge pier cover beams, which meets the needs of space and force, and the cost can be controlled within a reasonable range. [0003] Compared with square concr...
