     硅芯管較大牽引力實驗夾具，屬于建筑材料測試裝置領域。特征是包括擠緊內套筒和圓形的提拉盤塊，提拉盤塊設置在擠緊內套筒的內部，在提拉盤塊的上部設置提拉桿，提拉桿向上穿出擠緊內套筒；在擠緊內套筒的內壁上鉸接兩支以上的內壁弧形卡爪；提拉盤塊位于各內壁弧形卡爪之間；當向上移動提拉桿時，提拉盤塊能夠向外推動內壁弧形卡爪，令內壁弧形卡爪向外撐出，卡緊硅芯管的內壁。此裝置能夠合理夾緊硅芯管試件，不會因為夾具的夾持方式損傷試件，方便得到真實的實驗數據。新型(xing)裝置不會因為(wei)夾(jia)具的夾(jia)持(chi)方式損(sun)傷(shang)試件，反復(fu)使用仍不影響裝置的使用壽命(ming)，檢修率(lv)低，適(shi)宜推廣(guang)普(pu)及(ji)。
