CHEN LIHUA / ZHANG ENZHENG / LU CHUNCHANG / ZHANG LEI / YANG HAIQING

The invention relates to the technical field of steel bar connection, in particular to a steel bar quick connecting sleeve and a using method.The connecting sleeve comprises a circular-tube-shaped sleeve body with openings in the left side wall and the right side wall and a cylindrical alloy inner sleeve with an opening in the right side, and a welding through groove is formed in the sleeve left section; the inner diameter of the sleeve right section is matched with the outer diameter of the alloy inner sleeve, and the inner diameter of the alloy inner sleeve is matched with the outer diameter of a right connecting steel bar; the connecting sleeve is adopted to weld the left connecting steel bar and the right connecting steel bar and connect the left connecting steel bar and the right connecting steel bar with the high-frequency induction coil in a melting mode to form a whole, and by the adoption of the technical scheme, the machining cost of the connecting sleeve is reduced, the installation mode is simplified, and the service life of the connecting sleeve is prolonged. The connecting structure is particularly suitable for working places such as tunnels with narrow spaces, and the connecting effect is enhanced.

本发明涉及钢筋连接技术领域，具体涉及一种钢筋快速连接套筒及使用方法，其中，连接套筒，包括左右两侧壁开口的圆管状套筒本体和右边开口的圆筒状合金内套，在所述的套筒左段上设置有焊接通槽；所述套筒右段的内径与所述合金内套的外径相匹配，所述合金内套的内径与右连接钢筋的外径相匹配；所述合金内套的熔点低于所述的右连接钢筋的熔点，采用上述连接套筒将左连接钢筋和右连接钢筋进行焊接和高频感应线圈熔化连接后形成一体，采用发明的技术方案，简化了连接套筒的加工成本，简化了安装方式，特别适合在狭小空间的隧道等工作场所，增强了连接效果。
