Problems solved by technology

[0003] The existing bridge panels need to be connected to two adjacent bridge panels through connectors during laying. Most of the existing bridge panels are connected due to poor load-bearing effect at the joints between the two adjacent bridge panels. When the force is applied, the force on the panel cannot be offset in time, resulting in gaps easily appearing at the connection between two adjacent bridge panels, which will affect the safety performance of the bridge

Abstract

The invention discloses an anchoring connection device for a steel-concrete composite beam prefabricated concrete bridge deck, which belongs to the technical field of bridge construction and includes a panel one, one end of the first panel is connected to a second panel through a steel bar connector, and the inside of each panel is First transverse bars and longitudinal bars perpendicular to the first transverse bars are provided at equal intervals, and the reinforcing bar connector includes the first transverse bars, longitudinal bars perpendicular to the first transverse bars, and concrete poured outside the bars. In the present invention, through the arrangement of the connecting rod one through the steel bar connector and the L-shaped connecting plate, a closed connecting piece is formed between the connecting rod one and the two L-shaped connecting plates in the vertical position. When the connection between the two panels After the concrete is poured and solidified, the tensile stress of the concrete caused by the load can be reduced or offset by the connection between the closed connector and the poured concrete, so as to improve the load-bearing effect of the connection between two adjacent panels and reduce the load-bearing effect of the two adjacent panels. Probability of cracks occurring between panels.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to an anchor connection device for a prefabricated concrete bridge deck of a steel-concrete composite beam. Background technique [0002] The anchoring of steel bars means that the steel bars are wrapped in concrete to strengthen the connection between the concrete and the steel bars to make the building stronger. and bending moment, torque, etc.). [0003] The existing bridge panels need to be connected to two adjacent bridge panels through connectors during laying. Most of the existing bridge panels are connected due to poor load-bearing effect at the joints between the two adjacent bridge panels. When the force is applied, the force on the panels cannot be counteracted in time, resulting in gaps easily appearing at the connection between two adjacent bridge panels, which affects the safety performance of the bridge. Contents of the invention [0004] 1. Technical ...
