Steel strand prestress loss compensation mechanism in mechanical box girder and using method
The invention provides a steel strand prestress loss compensation mechanism in a mechanical box girder and a using method, and belongs to the technical field of bridge construction equipment. The mechanism comprises an anchorage device, a clamping block, a steel strand and a jack. The anchorage device sleeves the steel strand and is fixed with the steel strand through the clamping block, the jackis connected to an end part of the steel strand and tensions the steel strand, and a mechanical clamping block jacking mechanism is arranged between the anchorage device and the jack. By means of themechanism, the position of the clamping block can be firmly fixed, the clamping block cannot move outwards after the jack is detached, and the steel strand can be in a tensioned state all the time.
本发明提出了一种机械式箱梁中钢绞线预应力损失补偿机构及使用方法，属于桥梁施工设备技术领域，其具体包括锚具、夹块、钢绞线和千斤顶，锚具套在钢绞线上并通过夹块与钢绞线固定，千斤顶连接在钢绞线的端部并将钢绞线拉紧，锚具和千斤顶之间设置有机械式夹块顶紧机构。通过本发明的机构可将夹块的位置固定牢靠，在卸掉千斤顶之后夹块不会向外移动，钢绞线也会始终处于被拉紧的状态。
