Abstract
The invention relates to a steel strand connector which solves the problem that cement paste is easy to enter a space between an anchor piece with a ring-shaped cross section at an anchoring end of the traditional steel strand connector and an anchor ring so as to cause the anchoring end not to be tightly clamped before and in the process of stretch-drawing a steel strand, and the steel strand is pulled off in the process of stretch-drawing to influence the establishment of stretch-drawing force. One end of a steel sleeve is provided with an inner ledge hole, and an extrusion anchor piece is fixedly sleeved on a steel strand of the anchoring end in the steel sleeve; one end of the extrusion anchor piece is lap jointed on the inner ledge end face of the inner ledge hole, and the anchor piece with a ring-shaped cross section is fixedly sleeved on a steel strand of a stretch-drawing end; the anchor ring is sleeved on the anchor piece with a ring-shaped cross section; and the other end of the steel sleeve is fixedly sleeved on the anchor ring. The steel strand connector has simple structure and convenient construction and can effectively connect prestress steel strands to realize the sectional blanking and the sectional stretch-drawing of the prestress steel strands. The steel strand connector can be widely applied to the sectional stretch-drawing and the sectional extending of the steel strands in pretress concrete structures.
Description
Technical field
The present invention relates to a kind of steel strand connector.
Background technology
In the prestressed reinforced concrete construction, when the engineering of prestressed concrete is long, the stretch-draw prestressing force steel strand can cause bigger loss of prestress in the concrete end, need to adopt prestress steel twist wiring connector subsection tension prestress wire, to reduce the loss of prestress of prestressed concrete engineering.At present, the cross section of the anchored end of existing steel strand connector is between the anchor of annular and the anchor ring easily water inlet mud, cause steel strand before stretch-draw and stretching process in the anchored end clamping not tight, steel strand are pulled in the stretching process thereby cause, and influence the foundation of stretching force.
Summary of the invention
The objective of the invention is cross section for the anchored end that solves existing steel strand connector and be between the anchor of annular and the anchor ring easily water inlet mud, cause steel strand before stretch-draw and in the stretching process anchored end clamping do not cause tightly that steel strand are pulled in the stretching process, influence the problem of the foundation of stretching force, and then a kind of steel strand connector is provided.
The present invention solves the problems of the technologies described above the technical scheme of taking to be: steel strand connector of the present invention comprises anchor ring, cross section is the anchor and the steel bushing of annular, described connector also comprises the extruding anchor, one end of described steel bushing is provided with interior shoulder hole, described extruding anchor is solidly set on the steel strand of the anchored end in the steel bushing, one end of extruding anchor is overlapped on the interior shoulder end face in described interior shoulder hole, the anchor that described cross section is annular is solidly set on the steel strand of stretch-draw end, described anchor ring is sleeved on cross section and is on the anchor of annular, and the other end of described steel bushing is solidly set on the anchor ring.
The invention has the beneficial effects as follows: the present invention adopts the extruding anchor directly to be solidly set on the steel strand of the anchored end in the steel bushing, one end of extruding anchor is by interior shoulder stretch-draw steel strand, steel strand anchored end before stretch-draw and in the stretching process can not be subjected to the influence of cement paste, clamping is fastening, for necessary condition has been created in the foundation of stretching force; Simple in structure, the easy construction of the present invention can effectively connect prestress wire, realizes prestress wire segmentation blanking, subsection tension; The present invention can be widely used in steel strand subsection tension or the steel strand segmentation spreading in the prestressed reinforced concrete construction.
Description of drawings
Fig. 1 overall structure master of the present invention looks sectional view.
The specific embodiment
The specific embodiment one: as shown in Figure 1, the steel strand connector of present embodiment comprises anchor ring 1, cross section is the anchor 2 and the steel bushing 3 of annular, described connector also comprises extruding anchor 4, one end of described steel bushing 3 is provided with interior shoulder hole 5, described extruding anchor 4 is solidly set on the steel strand 7 of the anchored end in the steel bushing 3, one end of extruding anchor 4 is overlapped on the interior shoulder end face in described interior shoulder hole 5, the anchor 2 that described cross section is annular is solidly set on the steel strand 6 of stretch-draw end, described anchor ring 1 is sleeved on cross section and is on the anchor 2 of annular, and the other end of described steel bushing 3 is solidly set on the anchor ring 1.Anchor ring 1 is by being threaded on the steel bushing 3.The anchor 2 that described anchor ring 1 and cross section are annular is prior art, is that on 09 01st, 2004, notice of authorization are number for open in the utility model patent of CN 2637612Y on open.
The specific embodiment two: as shown in Figure 1, the material of the described extruding anchor 4 of present embodiment is made by stainless steel.So design can make the steel strand 7 of anchored end can bear powerful stretching force when stretch-draw.Other composition and annexation are identical with the specific embodiment one.
Operating principle:
At first anchor ring 1 is sleeved on cross section and is on the anchor 2 of annular, the anchor 2 that cross section is annular is solidly set on the steel strand 6 of stretch-draw end stretch-draw and anchoring steel strand; Extruding anchor 4 is solidly set on the steel strand 7 of the anchored end in the steel bushing 3, then steel bushing 3 is passed steel strand 7 and push anchor 4 and put to steel bushing 3; The other end of steel bushing 3 is solidly set on the anchor ring 1, builds the concrete of steel strand section to be connected, treat that this section concrete strength reaches regulation and requires after, stretch-draw segment steel twisted wire to be connected.Repeat above operation, can realize that the steel strand multistage reliably connects.
Claims (2)
