Manufacturing method of movable prestress tensioning back shore combined device
The invention relates to a manufacturing method of a movable prestress tensioning back shore combined device. The manufacturing method is characterized by comprising the following steps of a, manufacturing a prestress tensioning back shore structure; b, manufacturing a movable bracket structure; c, assembling the movable prestress tensioning back shore structure; d, manufacturing a movable jack steel frame; and e, combining the movable prestress tensioning back shore device. The manufacturing method of the movable prestress tensioning back shore combined device has the advantages that the device is simple in structure, convenient to manufacture, safe and reliable in engineering quality, suitable for tensioning of ultra-long prestress steel strands, capable of tensioning a plurality of steel strands at the same time and high in practicability, 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.
一种可移动预应力张拉顶撑组合装置的制作方法，其特征在于包括以下步骤：a、制作预应力张拉顶撑结构，b、制作可移动支架结构，c、可移动预应力张拉顶撑结构组装，d、制作可移动千斤顶钢框架，e、组合可移动预应力张拉顶撑装置。本发明的可移动预应力张拉顶撑组合装置的制作方法具有装置结构简单、制作方便，工程质量安全可靠，适于超长预应力钢绞线的张拉，能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。
