Abstract
The utility model relates to a steel strand connector, which comprises a first steel strand, a second steel strand, a connection sleeve, extrusion anchor pieces and dustproof linings, wherein the connection sleeve comprises a first sleeve and a second sleeve; inner ledge holes are formed in one end of the first sleeve and one end of the second sleeve; the first steel strand penetrates through the inner ledge hole in the first sleeve and is anchored by the extrusion anchor piece; the second steel strand penetrates through the inner ledge hole in the second sleeve and is anchored by the extrusion anchor piece; an external thread is formed on the outer surface of the other end of the first sleeve; an internal thread matched with the external thread of the first sleeve is formed on the inner surface of the other end of the second sleeve; and the dustproof linings are arranged between the inner ledge holes and the extrusion anchor pieces. The steel strand connector has the beneficial effects that the shortcoming that the anchor end cannot be tightly clamped before and when the steel strand is tensioned because cement slurry easily enters a space between the anchor piece and an anchor ring at the anchor end of the conventional steel strand connector is overcome; the strength of the steel strand connector is improved; and the working efficiency is improved.
Description
Technical field
The utility model relates to a kind of steel strand connector, belongs to anchor pole ground tackle apparatus field.
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; Be prone to water inlet mud between the anchor of the anchored end of existing steel strand connector and the anchor ring, cause steel strand before stretch-draw with stretching process in the anchored end clamping not tight, steel strand are pulled in the stretching process thereby cause; Influence the foundation of stretching force; Existing reinforcing bar connector insufficient strength between anchored end and the branch sleeve in assembling process is high, causes reinforcing bar and connector to come off easily, influences assembly quality and efficient.
The utility model content
The utility model technical problem to be solved is, overcomes the shortcoming of prior art, proposes a kind of simple in structure, steel strand connector that cost is low, improves the prestress steel twist wiring connector of working strength and efficient.
In order to solve above technical problem; The utility model provides a kind of steel strand connector; Comprise first steel strand, second steel strand, branch sleeve, extruding anchor and dustproof lining, said branch sleeve comprises first sleeve and second sleeve, and first sleeve and second sleeve, one end are equipped with interior shoulder hole; The shoulder nose end passed and with extruding anchor anchoring in first steel strand were provided with from first sleeve, and the shoulder nose end passed and with pushing the anchor anchoring in second steel strand were provided with from second sleeve; The first sleeve other end external surface is provided with external screw thread, and the second sleeve other end inner surface is provided with the internal thread that is used with the first sleeve external screw thread; Dustproof lining is located between interior shoulder hole and the extruding anchor.
Shoulder nose end cross section was a regular hexagon in aforesaid steel strand connector, first sleeve and second sleeve were provided with; Dustproof lining one end has boss, and dustproof lining has elasticity, and the internal diameter of dustproof lining is less than the steel strand diameter, and dirt-proof boot boss external diameter is greater than sleeve diameter.
The beneficial effect of the utility model is: solve between anchor and the anchor ring of anchored end of existing steel strand connector and be prone to water inlet mud; Cause steel strand before stretch-draw with stretching process in the not tight shortcoming of anchored end clamping; Improve the intensity of steel strand connector, increase work efficiency.

The specific embodiment
It is a kind of that present embodiment provides; Structure is as shown in Figure 1; Comprise first steel strand 1, second steel strand 2, branch sleeve, extruding anchor 7, dustproof lining 5 and dustproof lining 6, said branch sleeve comprises that first sleeve 3 and second sleeve, 4, the first sleeves 3 and second sleeve, 4 one ends are equipped with interior shoulder hole; The shoulder nose end passed and with extruding anchor 7 anchorings in first steel strand 1 were provided with from first sleeve 3, and the shoulder nose end passed and with pushing anchor 7 anchorings in second steel strand 2 were provided with from second sleeve 4; First sleeve, 3 other end external surfaces are provided with external screw thread, and second sleeve, 4 other end inner surfaces are provided with the internal thread that is used with first sleeve, 1 external screw thread; Dustproof lining 5 and dustproof lining 6 are located between interior shoulder hole and the extruding anchor.
Shoulder nose end cross section was a regular hexagon in aforesaid steel strand connector, first sleeve 3 and second sleeve 4 were provided with, and was of value to the assembling of first sleeve 3 and second sleeve 4; Dustproof lining 5 all has boss with dustproof lining 6 one ends; Dustproof lining 5 all has elasticity with dustproof lining 6; The internal diameter of dustproof lining 5 is less than first steel strand, 1 diameter; Dustproof lining 5 boss external diameters are greater than first sleeve, 3 internal diameters, and the internal diameter of dustproof lining 6 is less than second steel strand, 2 diameters, and dustproof lining 6 boss external diameters are greater than second sleeve, 4 internal diameters.
When actual installation is used; Earlier first sleeve 3 and second sleeve 4 are placed in first reinforcing bar 1 and second reinforcing bar 2 respectively; The lining 5 that will prevent dust again is assemblied between first sleeve 3 and first reinforcing bar 1, and dustproof lining 5 boss ends are positioned at first sleeve, 3 inboards, and dustproof lining 6 is assemblied between second sleeve 4 and second reinforcing bar 2; Dustproof lining 6 boss ends are positioned at second sleeve, 4 inboards; Live first steel strand 1 and second steel strand 2 with extruding anchor 7 anchors then, at last first sleeve 3 and second sleeve 4 are passed through screw fit, and implement pretension through the regular hexagon on first sleeve 3 and second sleeve 4.
Except that the foregoing description, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
