Manufacturing method of positioning device for batch tensioning of pre-tensioning method precast beam steel strands
The invention discloses a manufacturing method of a positioning device for batch tensioning of pre-tensioning method precast beam steel strands. The manufacturing method is characterized by comprisingthe following steps that a, a front panel and a rear front panel of the steel strand positioning device are manufactured; b, a plurality of layers of grid-shaped long-strip-shaped steel grating plates are manufactured between the front panel and the rear front panel according to the design; c, channel steel is welded around the front panel and the rear front panel of the steel strand positioningdevice; and d, a steel grating is manufactured by using a plurality of square steel cross braces, and the steel grating is mounted at the front end of the steel strand positioning device. The manufacturing method of the positioning device for batch tensioning of the pre-tensioning method precast beam steel strands has the advantages that the device is simple in structure, convenient to manufactureand safe and reliable in engineering quality, the ultra-long prestressed steel strands can be tensioned, meanwhile, the multiple steel strands are tensioned, each steel strand reaches a prestress design value, and a safety design for preventing the steel strands from disengaging from anchors and rebounding is provided.
一种用于先张法预制梁钢绞线批量张拉的定位装置制作方法，其特征在于包括以下步骤：a、制作钢绞线定位装置前面板和后前面板，b、根据设计在前面板和后前面板之间制作若干层方格状长条钢格板，c、在钢绞线定位装置前面板和后前面板四周分别焊接槽钢，d、用若干方钢横撑制作钢格栅，安装在钢绞线定位装置前端。本发明的用于先张法预制梁钢绞线批量张拉的定位装置制作方法具有装置结构简单、制作方便，工程质量安全可靠，可进行超长预应力钢绞线的张拉，同时多条钢绞线进行张拉，使每一根钢绞线达到预应力设计值和设有防钢绞线脱锚回弹安全设计的优点。
