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

Abstract
The invention discloses a pullout-resistant and non-shear-resistant stud conversion device and an operation method, comprising a stud head cap conversion device and a stud rod sleeve conversion device, the stud head cap conversion device consists of a stud head cap conversion device with a buckle The head metal cap and cap rubber ring, the cap rubber ring is located inside the metal cap of the stud head; the stud rod sleeve conversion device is composed of the stud rod metal sleeve and the stud rod rubber sleeve, the stud rod The rubber sleeve sits inside the metal sleeve. The device is simple to assemble and convenient to construct, and is not easily damaged 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...
