Connecting and tensioning method for steel strands
The invention relates to a connecting and tensioning method for steel strands, which comprises the following steps: providing a connecting piece, fixing the connecting piece at the end part of a first steel strand, and arranging a second steel strand in a U-shaped groove in a penetrating manner; a concrete layer is formed through pouring, the first steel strand and the second steel strand are embedded in the concrete layer, and a notch is formed in the position, corresponding to the connecting piece, of the concrete layer so that the tensioning end of the second steel strand can be exposed; and an anchor part is provided, the anchor part is installed at the tensioning end of the second steel strand and clamped in the clamping groove, the tensioning end of the second steel strand is tensioned through the jack, then the part, exposed out of the connecting piece, of the second steel strand is tensioned, and the notch is filled and leveled up through concrete. The problem that steel strand connection and tensioning are difficult at the same time is effectively solved, on the basis that two adjacent steel strands are connected, anchoring and tensioning of the steel strands can be achieved, the utilization rate of the ultrahigh-strength retard-bonded prestressed steel strands is increased, the construction cost is reduced, and the construction efficiency is improved.
本发明涉及一种用于钢绞线的连接张拉方法，包括如下步骤：提供连接件，将连接件固定于第一钢绞线的端部，将第二钢绞线穿设于U型槽；浇筑形成混凝土层，使得第一钢绞线和第二钢绞线埋设于混凝土层中且混凝土层对应连接件的位置形成缺口，以露出第二钢绞线的张拉端；提供锚件，将锚件安装于第二钢绞线的张拉端并卡设于卡接槽，利用千斤顶张拉第二钢绞线的张拉端，进而阶段第二钢绞线露出连接件的部分，并利用混凝土填平缺口。本发明有效地解决了同时实现钢绞线连接和张拉较为困难的问题，在连接相邻两根钢绞线的基础上，能够实现对钢绞线的锚固张拉，提高了超高强缓粘结预应力钢绞线的利用率，也降低了施工成本，提升了施工效率。
