Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in detail。
In order to make the purpose of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated。Should be appreciated that specific embodiment described herein is only in order to explain the present invention, is not intended to limit the present invention。
As shown in Figures 1 to 8, the callable prestress anchorage cable of the present embodiment, including steel strand wires 1, steel strand wires 1 are connected at least one Inner bolt head, the bottom of Inner bolt head is provided with base plate 2, base plate 2 is provided with the preformed hole 3 for cross-under steel strand wires 1, in the present embodiment, gear train 6 is welded on base plate 2, the axis of gear train 6 overlaps with the line of centres for the preformed hole 3 of cross-under steel strand wires 1 of two symmetries on base plate 2, base plate 2 be provided above seal closure 4, seal closure 4 is internally provided with, lower two gear shafts 5, gear shaft 5 is connected to a left side, each pair gear train 6 right, the structure of gear train 6 is as depicted in figs. 1 and 2, gear train 6 all includes two gears 7, the outer ring lateral margin of gear 7 is provided with circular groove 8, the circular groove 8 of two gears 7 of each gear train 6 forms the gap for holding steel strand wires 1 in opposite sides, in the present embodiment, the steel strand wires 1 being arranged in Inner bolt head are provided with screw thread, steel strand wires 1 are coupled with gear 7 by screw thread, the quantity of steel strand wires 1 is two, two steel strand wires 1 and are connected with two gears 7 of this gear train 6 through two the gap of gear train 6, concrete, one section, the end of steel strand wires 1 is constructed to the screw thread being coupled with gear train 6, make two steel strand wires 1 are each passed through the preformed hole 3 in the circular bottom plate 2 of welded gear group 6, and make two steel strand wires 1 one end with screw thread enter the circular groove 8 in the middle of gear train 6 successively, and keep the length that two steel strand wires 1 enter circular groove 8 equal, the box of the sealing more than made is called " Inner bolt head ", its structure is as shown in Figure 8。
