Abstract
The utility model relates to a prestressed anchorage cable free section steel strand wires positioning mechanism, including pvc pipe and locating rack, the pvc external diameter of pipe is less than the drilling internal diameter, and it is intraductal that the locating rack is located pvc, the locating rack includes a plurality of holding ring, and all the coincidence is just parallel with the pvc pipe in the axle center of all holding rings, and the steel strand wires radius is less than the holding ring internal diameter. This mechanism can fix a position prestressed anchorage cable free section steel strand wires in drilling between two parties, can prevent steel strand wires and drill hole wall contact, and simple structure is with low costs.
Description
Technical field
The utility model belongs to the realm of building construction, is specifically related to a kind of prestress anchorage cable free segment steel strand detent mechanism, locates between two parties in the borehole for prestress anchorage cable free segment steel strand.
Background technology
Deep foundation pit of construction support engineering often uses prestress anchorage cable, the anchoring section of prestress anchorage cable is fixed in hard rock stratum, free segment carries out stretch-draw in the borehole and applies pressure to rock stratum and carry out anchoring to unstable rock mass, prestress anchorage cable free segment steel strand often bend because of Action of Gravity Field, thus make steel strand not placed in the middle or not straight in the borehole, thus cause steel strand to contact with drill hole wall, easily there is corrosion, affect working life.
Utility model content
The purpose of this utility model is to provide a kind of prestress anchorage cable free segment steel strand detent mechanism, and prestress anchorage cable free segment steel strand can be located by this mechanism in the borehole between two parties, can prevent steel strand from contacting with drill hole wall, and structure is simple, and cost is low.
In order to solve above-mentioned technical problem, the technical solution of the utility model is:
A kind of prestress anchorage cable free segment steel strand detent mechanism, comprise pvc pipe and locating rack, pvc pipe external diameter is less than boring internal diameter, and locating rack is positioned at pvc pipe; Locating rack comprises several locating rings, and the axle center of all locating rings all overlaps and manages parallel with pvc, and steel strand radius is less than locating ring internal diameter.
Further, locating rack also comprises several support bars and connecting rod, support bar and pvc manage parallel and are uniformly distributed around locating ring, and all support bars and locating ring are connected into an entirety by connecting rod, and the radius of a circle that all support bars are formed is less than the internal diameter of pvc pipe.
Further, one end of connecting rod is fixed on support bar, the other end is fixed on locating ring, and connecting rod is uniformly distributed along locating ring cylindrical.
Further, the quantity of support bar is 3.
The beneficial effects of the utility model are:
1. during work, establish in the borehole by pvc pipe, pvc pipe can prevent steel strand from contacting with drill hole wall, and steel strand pass the locating ring on locating rack successively and locate between two parties under the restriction of locating ring, can not bend; The utility model structure is simple, and cost is low.
2. support bar contacts the effect both serving supporting and location ring and in turn ensure that the axle center of locating ring is managed parallel with pvc with pvc inside pipe wall; The radius of a circle that support bar is formed is less than the internal diameter of pvc pipe, and locating rack can be free to slide in pvc pipe, by traction locating rack, and can be straight by steel strand from front to back.
3., when making, first fixed connecting rod is fixed support bar again, and connecting rod is uniformly distributed the installation being conducive to support bar.
4. support bar adopts two, structural instability, and support bar adopts more than four, and consumptive material is large, and add cost and Production Time, support bar adopts three, both ensure that Stability Analysis of Structures again reduces cost.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further detailed.
As depicted in figs. 1 and 2, a kind of prestress anchorage cable free segment steel strand detent mechanism, comprise pvc pipe 5 and locating rack, pvc pipe 5 external diameter is less than boring internal diameter, and locating rack is positioned at pvc pipe 5; Locating rack comprises several locating rings 3, and the axle center of all locating rings 3 all overlaps and parallel with pvc pipe 5, and steel strand 1 radius is less than locating ring 3 internal diameter.During work, establish in the borehole by pvc pipe 5, pvc pipe 5 can prevent steel strand 1 from contacting with drill hole wall, and steel strand 1 pass the locating ring 3 on locating rack successively and locate between two parties under the restriction of locating ring 3, can not bend; The utility model structure is simple, and cost is low.
As depicted in figs. 1 and 2, in the present embodiment, locating rack also comprises several support bars 2 and connecting rod 4, support bar 2 is parallel with pvc pipe 5 and be uniformly distributed around locating ring 3, all support bars 2 and locating ring 3 are connected into an entirety (in the present embodiment by connecting rod 4, connecting rod 4 one end is fixed on support bar 2, the other end is fixed on locating ring 3, connecting rod 4 is uniformly distributed along locating ring 3 cylindrical, the number of each locating ring 3 upper connecting rod 4 equals the number of support bar 2, during making, first fixed connecting rod 4 fixed support bar 2 again, connecting rod 4 is uniformly distributed the installation being conducive to support bar 2), the radius of a circle that all support bars 2 are formed is slightly less than the internal diameter of pvc pipe 5.The effect that support bar 2 and pvc pipe 5 contact internal walls had both served supporting and location ring 3 in turn ensure that the axle center of locating ring 3 is parallel with pvc pipe 5; The radius of a circle that support bar 2 is formed is less than the internal diameter of pvc pipe 5, locating rack can be free to slide in pvc pipe 5, by traction locating rack, can from front to back by straight for steel strand 1 (if locating rack is shorter, can by the mode of traction locating rack by straight for steel strand 1, if locating rack grows to the whole process covering free segment steel strand, then without the need to drawing this step straight).
As depicted in figs. 1 and 2, in the present embodiment, the quantity of support bar 2 is 3.Support bar 2 adopts two, structural instability, and support bar 2 adopts more than four, and consumptive material is large, and add cost and Production Time, support bar 2 adopts three, both ensure that Stability Analysis of Structures again reduces cost.
Should be understood that, for those of ordinary skills, can be improved according to the above description or convert, and all these improve and convert the protection domain that all should belong to the utility model claims.
