The T-shaped slotted hole connecting piece is composed of a steel structure, and the steel structure comprises a steel plate mother plate (1) and a plurality of pore plates (2). The pore plate (2) is vertically and fixedly arranged on the top surface of the steel plate mother plate (1) along the thickness direction; a flange plate (3) is fixedly arranged at the top of the pore plate (2) along the height direction; a notch (5) is formed in the pore plate (2) in the thickness direction, an in-hole steel bar (4) is installed in the notch (5), and a flange plate (6) is fixedly arranged at the bottom of the notch (5); a triangular prism steel block (7) is reserved at each of the edges of the two ends of the bottom of the notch (5) in the width direction; concrete is poured on the periphery of the steel structure. The method has the following advantages that the local tensile stress of concrete is reduced, the influence of stress concentration on the connecting piece is reduced, the stress performance of the steel-concrete joint part is enhanced, and the field construction efficiency is improved.
Description
technical field [0001] The invention relates to the field of bridge engineering, in particular to a T-shaped ribbed slot-hole connector applied to a steel-concrete composite structure. Background technique [0002] The bridge steel-concrete connection is the key part connecting the load-bearing structure of the bridge with the bridge deck. However, at present, the connection of steel-concrete composite girder bridges is often equipped with welding stud connectors and shear connectors, which requires a large number of connections to be arranged in a limited space. The complex structure affects the pouring quality of concrete, and the force is not clear, which is prone to stress concentration, reducing construction efficiency and economic benefits. [0003] The T-slotted connector has obvious advantages in steel-concrete composite bridges. It combines the advantages of flange plate pull-out resistance and aerial reinforcement shear resistance. The formed T-slotted plate connec...
