Description

Technical Field

[0001] The present invention relates to the technical field of bridge engineering, and in particular to a connection structure between a steel cap beam and a concrete bridge pier. Background Art

[0002] Traditional cast-in-place concrete cap beams require scaffolding, occupying significant space, and requiring long construction times, significantly impacting traffic and the environment during construction. Precast concrete cap beams, on the other hand, present the problem of excessive lifting weight. This necessitates segmentation and subsequent assembly during construction, increasing the number of construction steps and introducing technical difficulties. Steel cap beams eliminate the issues of excessive lifting weight and long construction times. However, the connection methods currently used between the steel cap beam and the concrete piers are primarily steel column insertion and steel shoe insertion. In the steel column insertion method, the steel column of the portal pier of the steel cap beam is connected to the concrete pier by inserting the steel column. The steel column is inserted 4 to 6 meters into the concrete, forming a steel-concrete structure. The cross-sectional dimensions of the steel column are approximately 60 cm smaller than those of the concrete pier (meaning the outer concrete coating is approximately 30 cm thick). During construction, after the portal steel cap beam and steel columns are factory-fabricated, they are assembled on-site into integral segments and hoisted and installed as a whole. After installation, the outer concrete coating and inner concrete filling of the steel column are poured. This connection method connects the steel cap beam to the concrete pier column solely through concrete, resulting in poor connection reliability. In the steel shoe type, the pier column reinforcement is cut off at the pier top, and the concrete pier column and thin-walled steel box cap beam are consolidated via a steel shoe installed at the pier top. The steel shoe is typically designed as a 20mm thick trapezoidal steel plate, welded to the cap beam base plate and the pier top steel hoops, and arranged at regular intervals around the pier column. This connection method requires the steel shoes to be individually positioned on-site, which is time-consuming and labor-intensive, making construction difficult.

[0003] Therefore, providing a steel cap beam and concrete bridge pier connection structure with a short construction period, small lifting weight, good connection reliability, and simple construction has become an urgent problem to be solved by technical personnel in this field.
