Connecting and tensioning device for steel strand
The invention relates to a connecting and tensioning device for steel strands, the connecting and tensioning device is used for connecting a first steel strand and a second steel strand to be tensioned, and the connecting and tensioning device comprises a base, a tensioning device and a tensioning device, the base is provided with a through hole for the first steel strand to penetrate through; the fixing block is fixed at the top of the base, and a U-shaped groove for a second steel strand to penetrate through is formed in the side part, far away from the base, of the fixing block; the inner wall of the U-shaped groove does not sink inwards to form a clamping groove; the anchor part is used for being installed at the end of the second steel strand and matched with the clamping groove, and the second steel strand is installed in the U-shaped groove by being clamped in the clamping groove through the anchor part. 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装置，连接张拉装置供连接第一钢绞线和待张拉的第二钢绞线，该连接张拉装置包括：底座，底座开设有供第一钢绞线穿过的通孔；固定于底座的顶部的固定块，该固定块远离底座的侧部开设有供第二钢绞线穿过的U型槽；U型槽的内壁有会不向内凹陷以形成卡接槽；以及供安装于第二钢绞线的端部且与卡接槽相匹配的锚件，通过锚件卡设于卡接槽，使得第二钢绞线安装于U型槽。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。
