Positioning device for prestressed steel strand in prestressed beam and construction method of positioning device
The invention discloses a positioning device for a prestressed steel strand in a prestressed beam and a construction method thereof.The positioning device comprises a vertical pull rod, a plurality of transverse adjusting rods and fixing rib bases arranged on the transverse adjusting rods, the vertical pull rod is arranged in the prestressed beam in the vertical direction, and fixing steel plates are arranged at the two ends of the vertical pull rod; the fixed steel plate is bound and fixed in the prestressed concrete beam; the transverse adjusting rod is horizontally arranged on the vertical pull rod in the distribution direction of the prestressed steel strands and movably connected with the vertical pull rod, and a positioning adjusting groove is formed in the transverse adjusting rod. The fixing rib base is movably arranged in the positioning adjusting groove and used in cooperation with the prestressed steel strand. According to the positioning device, the vertical pull rod, the transverse adjusting rod and the fixing rib base are arranged, so that the prestressed steel strand in the prestressed beam can be flexibly positioned according to needs during use, and the positioning device has the advantages of being simple in structure, flexible and convenient to use and high in positioning efficiency.
本发明公开了一种预应力梁中预应力钢绞线的定位装置及其施工方法，所述定位装置包括竖向拉杆、若干横向调节杆和设置在横向调节杆上的固定筋座，所述竖向拉杆在预应力梁中沿竖直方向设置，且在竖向拉杆两端设置有固定钢板，固定钢板绑扎固定在预应力混凝土梁内；所述横向调节杆沿预应力钢绞线分布方向水平设置在竖向拉杆上，与竖向拉杆活动连接，且在横向调节杆上设置有定位调节槽；所述固定筋座活动设置在定位调节槽内，且与预应力钢绞线配合使用；本定位装置通过竖向拉杆、横向调节杆和固定筋座的设置，在使用时能够灵活的根据需要对预应力梁中预应力钢绞线进行定位，具有结构简单、使用灵活方便和定位效率高的特点。
