Abstract
The utility model discloses a cone pipe for a steel strand prestress anchoring system. The cone pipe comprises three clamp sheets (1) and a hoop ring (2), wherein the clamp sheets (1) have the same size and are combined into a cone table (3), the center position of the cone table (3) is provided with a through hole (4), internal screw threads are arranged in the through hole (4), a groove (5) is arranged on the cone surface arranged under the cone table (3), the hoop ring (2) is arranged in the groove (5), and the hoop ring (2) is an elastic ring. The cone pipe has the beneficial effects that the cone pipe is made into a cone table shape, after the steel strand is covered by the center hole, the cone pipe is inserted into an anchoring ring from the fine end, the diameter of the thick end is greater than the diameter of the anchoring ring hole, the cone pipe cannot enter the anchoring ring hole, when the cone pipe needs to retracts back, the cone pipe positioned in the end part needs to be continuously pulled into the anchoring ring, the continuous contraction is required when the thick end of the cone pipe needs to enter the anchoring ring, and the end part of the steel strand can be tightly clamped.
Description
Technical field
The utility model relates to a kind of bridge construction and uses utensil, particularly relates to a kind of Taper Pipe that is used for the steel strand prestress anchor system.
Background technology
Prestress wire is the stranded steel cable that is made up of 2,3,7 or 19 high-tensile steel wires; And through the processing (stabilization processes) that eliminates stress; Be fit to prestressed concrete or similar applications,, nowadays be usually used in the structure of reinforced concrete of bridge because prestress wire has good, the advantage such as more straight and upright upon deployment of intensity height, relaxation property; To increase the crack resistance and the tolerances of bridge; But steel strand in use produce retraction probably, cause prestressed loss, so the termination of steel strand is fixing extremely important.Fixed system many employings in existing steel strand termination are provided with female anchor ring and fix, and after the anchor ring turn is fixed on the steel strand, seal up for safekeeping in concrete again, when steel strand will bounce back, are promptly blocked by the screw thread in the anchor ring.But the screw thread in the anchor ring is in use for some time, the smoothness that may become because of the friction that does not stop, and its dynamics of blocking steel strand promptly diminishes, and possibly have the situation generation that steel strand are shaken off.
The utility model content
The purpose of the utility model promptly is to overcome the deficiency of present technology, and a kind of Taper Pipe that is used for the steel strand prestress anchor system is provided, and it is arranged to frustum; Behind the centre bore parcel steel strand; Insert in the anchor ring hole from a thin end, a thick end is bigger than anchor ring bore dia, then can not get in the anchor ring hole again; When steel strand will bounce back; Promptly to constantly the Taper Pipe that is positioned at the termination be drawn in anchor ring, promptly need constantly dwindle, just can block the termination of steel strand inflexibly but the thick end of Taper Pipe will get into anchor ring.
The utility model is realized through following technical scheme: a kind of Taper Pipe that is used for the steel strand prestress anchor system; Comprise three intermediate plates of the same size and garter spring, described three intermediate plates are combined into a frustum, and the center of frustum is provided with a through hole; Be provided with internal thread in the through hole; The conical surface of frustum below is provided with groove, and described garter spring promptly is arranged in the groove, and garter spring is an elastic ring.
The direction of described through hole is consistent with the direction of principal axis of frustum.
The diameter up and down of described through hole is consistent.
Slit between the described intermediate plate is vertical with the disc up and down of frustum.
The beneficial effect of the utility model is: be arranged to frustum, behind the centre bore parcel steel strand, insert in the anchor ring from a thin end again; A thick end is bigger than anchor ring bore dia; Then can not get in the anchor ring hole, when steel strand will bounce back, promptly will constantly the Taper Pipe that is positioned at the termination be drawn in anchor ring; But the end that Taper Pipe is thick will get into anchor ring promptly need constantly be dwindled, and just can block the termination of steel strand inflexibly.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the structural representation of intermediate plate;
Among the figure, 1-intermediate plate, 2-garter spring, 3-frustum, 4-through hole, 5-groove, 6-slit.
The specific embodiment
Below in conjunction with embodiment the utility model is done further to specify, but the structure of the utility model is not limited only to following examples:
Like Fig. 1, shown in Figure 2, a kind of Taper Pipe that is used for the steel strand prestress anchor system comprises three intermediate plates 1 of the same size and garter spring 2; Described three intermediate plates 1 are combined into a frustum 3, and the center of frustum 3 is provided with a through hole 4, is provided with internal thread in the through hole 4; The conical surface of frustum 3 belows is provided with groove 5; Described garter spring 2 promptly is arranged in the groove 5, and garter spring 2 is an elastic ring, and garter spring 2 plays tingle 1.
The operating principle of the utility model: after steel strand inserted in the anchor ring, promptly stretched out from the anchor ring hole steel strand termination, and frustum 3 is through on the steel strand from the steel strand end; During use, the diameter of through hole 4 should be less than the diameter of steel strand, thereby three intermediate plates 1 are because garter spring 2 circumferential forces parcel steel strand; Garter spring 2 is elastic rings; Slit 6 between the intermediate plate 1 promptly becomes greatly, and the thin end of frustum 3 is at front end, and a thin end can get in the anchor ring hole; But a thick end designs greatlyyer than anchor ring hole, has then got into not the anchor ring hole; When steel strand need bounce back, then constantly frustum 3 is drawn in the anchor ring hole, the slit between the intermediate plate 1 is then constantly dwindled, and the screw thread of intermediate plate inboard then constantly increases the interlock dynamics of steel strand, reaches the effect that needs.
