Steel strand clamping piece mounting structure and mounting method
The invention relates to the technical field of building construction, especially to a steel strand clamping piece mounting structure and a mounting method. A sleeve is arranged on the outer side of asteel strand to be tensioned in a sleeving mode, the outer diameter of a first end of the sleeve is larger than the inner diameter of the steel strand clamping piece and smaller than the outer diameter of the steel strand clamping piece, and therefore the head of the steel strand clamping piece can be fed into a conical hole of an anchorage device through the sleeve; then the sleeve is moved, sothat a certain distance is formed between the sleeve and the steel strand clamping piece; then inertia force is applied to the steel strand clamping piece along the steel strand to be tensioned by using the sleeve, and the steps of moving the sleeve and using the sleeve to apply inertial force to the steel strand clamp are carried out for several times until the steel strand clamping piece is mounted in place. The mounting structure is easy to obtain materials, easy to manufacture and convenient to carry, multiple operation points can be used at the same time and do not interfere with one another, the mounting speed is high, inertia force can be applied to the two separated clamping pieces at the same time, the clamping pieces can enter an anchorage device synchronously, and the prestresstensioning construction quality is improved.
本发明涉及建筑施工技术领域，尤其涉及一种钢绞线夹片安装结构及安装方法，通过将套筒套设于待张拉钢绞线的外侧，且设置该套筒的第一端部的外径大于钢绞线夹片的内径并小于钢绞线夹片的外径，从而可以利用套筒将该钢绞线夹片的头部送入锚具的锥形孔中；之后移动套筒，以使得该套筒与钢绞线夹片之间具有一定间距；然后利用该套筒顺着待张拉钢绞线向钢绞线夹片施加惯性力，并多次进行移动套筒和利用套筒向钢绞线夹片施加惯性力的步骤，直至该钢绞线夹片安装到位；该安装结构材料易得，制作简单，携带方便，多个作业点可同时使用，互不干扰，安装速度快，能同时对分离的两个夹片施加惯性力，使得夹片同步进入锚具，提高了预应力张拉施工质量。
