Half-thread glue injection type connecting sleeve design method, thread glue injection type steel bar connecting sleeve, and mounting method thereof
The invention discloses a half-thread glue injection type connecting sleeve design method, a half-thread glue injection type steel bar connecting sleeve, and a mounting method thereof. The half-thread glue injection type connecting sleeve is formed by combining a steel sleeve, two steel bars with threads at the ends, and an adhesive. One end of the inner surface of the steel sleeve and the outer surfaces of the ends of the corresponding reinforcing steel bars are machined into threads which are in weak engagement. After the steel sleeve is screwed with the two reinforcing steel bars, internal gaps between the steel sleeve and the reinforcing steel bars are filled with the adhesive, and the two reinforcing steel bars are connected into a whole after the adhesive is cured. Thread pitch of the weak occlusion threads is long, and thread teeth are narrow, so that the steel sleeve can connect two steel bars at any interval, and the other ends of the weak occlusion threads are in weak occlusion connection. After the gaps between the steel sleeve and the weakly-engaged reinforcing steel bars are filled with the adhesive, the strong connection between the two reinforcing steel bars by the connecting sleeve can be realized; and the required connecting strength index can be met by adjusting the length of a connecting thread section between the steel sleeve and the weakly-engaged steel bars.
一种半螺纹注胶式连接套筒设计方法、半螺纹注胶式钢筋连接套筒及其安装方法。半螺纹注胶式连接套筒由钢套筒、两根端部带螺纹的钢筋和粘结胶组合而成。其中钢套筒内表面的一端及所对应的钢筋端部外表面加工为互相弱咬合的螺纹，钢套筒与两根钢筋旋合后，在钢套筒与钢筋之间的内部空隙注满粘结胶，胶固化后将两根钢筋连为一体。弱咬合螺纹的螺距较长、螺牙较窄，可以实现钢套筒对两根任意间距钢筋的连接，另一端为弱咬合连接；钢套筒与弱咬合钢筋之间的间隙上注满粘结胶后可实现连接套筒对两根钢筋之间的强连接；通过调节钢套筒与弱咬合钢筋之间连接螺纹段的长度，可满足所需的连接强度指标。
