Hollow prestressed steel strand
The invention relates to a hollow prestressed steel strand, and relates to the technical field of constructional engineering materials, the hollow prestressed steel strand comprises a strand body, a plurality of uniformly distributed connecting joints are arranged on the outer side of the strand body, and a plurality of groups of positioning support assemblies uniformly distributed around the strand body are arranged between the adjacent connecting joints; the positioning and supporting assembly comprises a first connecting rod and a second connecting rod which are parallel and opposite, one end of the first connecting rod is installed on one connecting joint, one end of the second connecting rod is installed on the other connecting joint, an arc-shaped supporting block is hinged to one end of the first connecting rod, and the other end of the first connecting rod is hinged to the other end of the second connecting rod. A limiting block abuts against the arc face of the side, away from the second connecting rod, of the supporting block, the limiting block is slidably connected to the first connecting rod, and the limiting block is rotationally connected with the second connecting rod. The corrugated pipe connecting structure has the effect of improving the connecting firmness of the steel strand and the corrugated pipe.
本申请涉及一种中空预应力钢绞线，涉及建筑工程材料的技术领域，包括线体，所述线体外侧设有若干均匀分布的连接节，相邻所述连接节之间设有多组绕所述线体均匀分布的定位支撑组件，所述定位支撑组件包括平行且相对的第一连接杆和第二连接杆，所述第一连接杆的一端安装在一个所述连接节上，所述第二连接杆的一端安装在另一个所述连接节上，所述第一连接杆的一端铰接有弧形的支撑块，所述支撑块远离所述第二连接杆的一侧的弧面上抵接有限位块，所述限位块滑动连接在所述第一连接杆上，且所述限位块与所述第二连接杆转动连接。本申请具有提高钢绞线和波纹管连接牢固性的效果。
