Problems solved by technology
However, the inventors found that the disadvantages of this type of anti-pull and non-shear stud structure are that the low-elastic-modulus material has a large amount of work on site, and the low-elastic-modulus material is easily damaged, dropped, and lacks high efficiency during the concrete vibration process. And standardized construction tools and construction methods, resulting in the inability to fully realize the role of anti-pull and non-shear studs, greatly affecting the construction and structural quality

The invention discloses a conversion device of an uplift-restricted and slip-permitted stud connector and an operation method. The device comprises a stud head cap conversion device and a stud rod sleeve conversion device, wherein the stud head cap conversion device is formed by a stud head metal cap provided with snaps and a cap rubber ring, and the cap rubber ring is located inside the stud headmetal cap. The stud rod sleeve conversion device is formed by a stud rod metal sleeve and a stud rod rubber sleeve, wherein the stud rod rubber sleeve is positioned inside the stud rod metal sleeve.The device has the advantages of being simple in assembly, convenient to construct and not prone to damage during concrete pouring construction.
Description
technical field [0001] The invention relates to the technical field of bridges used in civil engineering, and more particularly relates to a conversion device and an operation method for a pullout-resistant and non-shear-resistant stud. Background technique [0002] With the rapid development of my country's social economy, road traffic construction has also been developed accordingly. In order to adapt to the call for the conversion of new and old kinetic energy, steel-concrete composite girder bridges are more and more widely used in highway bridge construction because of their advantages such as light structure, convenient construction, engineering cost, and low environmental impact. [0003] The steel-concrete composite beam generally connects the lower steel beam and the concrete slab as a whole through stud connectors. For the steel-concrete composite beam whose boundary condition is simply supported, under the action of positive bending moment, the lower steel beam m...
