Pre-tensioned prestressed reinforced concrete precast beam
The invention discloses a pre-tensioning method prestressed reinforced concrete precast beam, which belongs to the technical field of precast beams, and comprises a beam body, a lower prestressed tendon, an upper prestressed tendon, a corrugated sleeve, a suspension positioning rod, a fastening mechanism, a supporting steel bar, a U-shaped steel bar, a supporting positioning mechanism and a pressing positioning mechanism, through mutual cooperation of the two corrugated sleeves, the supporting and positioning mechanism, the pressing and positioning mechanism and the fastening mechanism, the device is placed in a pouring area through a suspension supporting rod, so that penetrating holes of prestressed tendons are coaxially distributed with a supporting groove and a pressing groove correspondingly, and preliminary manufacturing of a steel reinforcement framework is formed; the operation difficulty of binding the supporting steel bars and the lower prestressed tendons and binding the U-shaped steel bars and the upper prestressed tendons is lowered, the manufacturing speed of the steel bar framework is effectively increased, and therefore the machining speed of the reinforced concrete precast beam is increased, full supporting and limiting treatment is formed when the prestressed tendons are arranged in a penetrating mode, and the construction efficiency is improved. And the bending phenomenon of the prestressed tendons during perforation is effectively avoided.
本发明公开了一种先张法预应力钢筋砼预制梁，属于预制梁技术领域，包括梁体，还包括下预应力筋、上预应力筋、波纹套管、悬吊定位杆、紧固机构、支撑钢筋、U型钢筋、支撑定位机构和按压定位机构；本发明通过两个波纹套管、支撑定位机构、按压定位机构以及紧固机构的相互配合作用，通过悬吊支撑杆将其放置于浇筑区域，使得预应力筋的穿设孔分别与支撑槽和按压槽呈同轴分布，形成钢筋骨架的初步制作，简化了支撑钢筋与下预应力筋、U型钢筋与上预应力筋的绑扎操作难度，有效提高钢筋骨架制作的速率，从而提高钢筋砼预制梁的加工速率，并且形成了对预应力筋进行穿设时的充分支撑以及限位处理，有效避免预应力筋在穿孔时发生弯曲现象。
