The utility model provides an integral prestressing bundle-piercing traction head, which comprises a cone sleeve, a clamp, a traction sleeve and a traction ring. The cone sleeve is provided with a cone hole, a cone hole is matched with a clamp piece, a first through hole is arranged in the clamp piece, a groove matched with the cone sleeve is arranged in the traction sleeve, a second through hole connecting part of the traction ring is arranged in the traction sleeve, and the steel strand passes through the first through hole Connector with second through hole. The steel strand of the utility model is connected with the connecting piece through the first through hole and the second through hole in turn, and pulls out multiple strands by pulling the traction ring connected to the connecting piece. After the steel strand passes through the first through hole and the second through hole, the clamp piece is connected with the connecting piece, and then the taper sleeve is fed into the groove sleeve to the clamp piece. When the steel strand is pulled, the taper sleeve and the clamp piece are pulled against each other. The utility model is tightened on the wall of the groove to prevent the steel strand from leaving the traction sleeve. The traction sleeve moves along the channel with the traction ring. The utility model has simple structure and strong practicability.
【技术实现步骤摘要】
一种整体预应力穿束牵引头
本技术涉及施工领域,具体涉及一种整体预应力穿束牵引头。
技术介绍
在预应力施工中,由于交叉作业,施工人员在施工过程中造成波纹管定位移位、波浪形、水化热使波纹管变形、波纹管质量不好(未扣合好)、孔道长(80~120m)摩阻太大、浇筑砼时波纹管振捣烂使砼灌入,安装钢筋位置不好使波纹管变形等等;以前穿束作法:单根钢绞线硬穿、穿线机硬穿,不通的地方开仓;整束的将钢绞线焊在一起约16~20cm,用钢筋焊挂钩(8cm)钢丝绳牵引从孔道拉出,但都因种种原因不够顺畅,要么头子太长,要么钢丝绳拉断,使整束穿索困难。
技术实现思路
本技术要解决的问题是针对现有技术中所存在的上述不足而提供一种整体预应力穿束牵引头方便牵引钢绞线。为实现上述目的,本技术采用了如下的技术方案:一种整体预应力穿束牵引头,包括锥套、夹片、牵引套和牵引环,所述锥套设有锥形孔,所述锥形孔与所述夹片相适配,所述夹片设有第一通孔,所述牵引套设有与所述锥套相适配的凹槽,所述牵引套设有连通所述第一通孔的第二通孔,所述牵引环连接连接件,钢绞线依次穿过所述第一通孔和第二通孔连接所述连接件。进一步,所述第二通孔维螺纹通孔,所述连接件与所述第二通孔螺纹连接。进一步,所述连接件连接锁紧环,所述锁紧环与所述第二通孔过盈配合,所述锁紧环与所述钢绞线连接。相比于现有技术,本技术具有如下有益效果:本技术通过将多根钢绞线端头氧焊在一起,然后预留并伸出中间的钢绞线依次穿过所述第一通孔和第二通孔与所述连件件连接,通过拉动连接在所述连接件上的所述牵引环从而将多根钢绞线拉出,钢绞线穿过所述第一通孔和第二通孔后与所述连接件连接 ...
