Abstract
The invention discloses a connector of steel stranded wires and finished twisted steel. The connector comprises a steel stranded wire anchor plate, a connection cylinder, wedge-shaped clamping pieces, disc springs, a pressure plate and bolts. The steel stranded wire anchor plate is a cylinder, whose the outer surface is provided with external threads; the external threads of the cylinder are matched with internal threads of the front segment of the connection cylinder; the steel stranded wire anchor plate is provided with taper-shaped through holes with large-diameter holes facing inwards along the axial direction; the wedge-shaped clamping pieces matched with the taper-shaped through holes are arranged in the taper-shaped through holes; the pressure plate is fixed on the steel stranded wire anchor plate positioned at one ends of the large-diameter holes of the taper-shaped through holes by the bolts; the disc springs are arranged among the pressure plate and the wedge-shaped clamping pieces; and the rear segment of the connection cylinder is provided with an internal threaded hole matched with the external threads of the finished twisted steel. The connector has the advantages of simplicity in structure, convenience in assembly and reliability in work, and can be applied to segmented lengthening and tensioning of the steel stranded wires and the finished twisted steel in a prestressed concrete structure.
Description
Technical field
The present invention relates to a kind of device that steel strand and finish rolling deformed bar reliably are connected.
Background technology
Steel strand and finish rolling deformed bar are two kinds of the most frequently used in prestressed reinforced concrete construction presstressed reinforcing steels; These two kinds of presstressed reinforcing steels can adopt connector segmentation spreading according to the needs of construction; But the connector of prior art is only applicable to the connection between the steel strand or between the finish rolling deformed bar; And there are not a kind of connector that can connect steel strand and finish rolling deformed bar, the demand that connects between the presstressed reinforcing steel of these two kinds of different qualities in the time of engineering construction can't being satisfied.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, easy construction, the reliable steel strand of connection and finish rolling deformed bar connector.
Technical scheme of the present invention is: a kind of steel strand and finish rolling deformed bar connector comprise steel strand anchor slab, connecting cylinder, wedge shape intermediate plate, dish spring, pressing plate and screw; Said steel strand anchor slab is that external surface is provided with externally threaded cylinder, and cylindrical external screw thread cooperates with the inner thread of connecting cylinder leading portion; On the steel strand anchor slab, in axial direction be provided with major diameter mouth conical through-hole inwardly; In conical through-hole, be provided with the wedge shape intermediate plate adaptive with it; On the steel strand anchor slab of major diameter mouth one end that is positioned at conical through-hole, pressing plate is arranged through screw; Between pressing plate and wedge shape intermediate plate, be provided with the dish spring; The back segment of said connecting cylinder is provided with and the suitable inner bolt hole of the external screw thread of finish rolling deformed bar.
Wherein, on the said pressing plate with the steel strand anchor slab on the conical through-hole corresponding section be provided with and the suitable through hole of steel strand external diameter.
The invention has the beneficial effects as follows: the present invention is simple in structure, and is easy to assembly; Prove that through experimental examination and engineering practical application the connector reliable operation can be applicable to steel strand and finish rolling deformed bar segmentation spreading and stretch-draw in the prestressed reinforced concrete construction.
Description of drawings

Be labeled as among the figure, 1. steel strand anchor slab, 2. connecting cylinder, 3. intermediate plate, 4. dish spring, 5. pressing plate, 6. screw, 7. steel strand, 8. finish rolling deformed bar.
The specific embodiment
Like Fig. 1, shown in 2, a kind of steel strand of the present invention and finish rolling deformed bar connector comprise steel strand anchor slab 1, connecting cylinder 2, wedge shape intermediate plate 3, dish spring 4, pressing plate 5 and screw 6.Steel strand anchor slab 1 is externally threaded cylinder for outer wall is provided with, and cylindrical external screw thread is connected with the inner thread of connecting cylinder 2 leading portions.One or more major diameter mouths conical through-hole inwardly in axial direction is set on steel strand anchor slab 1; The center of circle of conical through-hole evenly distributes around the axle center of steel strand anchor slab 1; Be positioned at making a concerted effort when making steel strand tension on the axle center of anchor slab 1; Be three conical through-holes in the present embodiment, the center of circle of these three conical through-holes is distributed on the peripheral same circumference in the axle center of steel strand anchor slab 1.Adaptive with it wedge shape intermediate plate 3 is all arranged in each conical through-hole; On the steel strand anchor slab 1 of major diameter mouth one end that is positioned at conical through-hole, be fixed with pressing plate 5, between wedge shape intermediate plate 3 bottoms and pressing plate 5, be provided with dish spring 4,, can regulate the thrust of dish spring 4 through rotary screw 6 through screw 6.On the said pressing plate 5 with steel strand anchor slab 1 on the conical through-hole corresponding section be provided with and the suitable through hole of steel strand 7 diameters, make things convenient for steel strand 7 to pass.The back segment of connecting cylinder 2 be provided with one with the suitable inner bolt hole of the external screw thread of finish rolling deformed bar 8, this inner bolt hole is positioned on the axle center of connecting cylinder 2.
Operating principle:
At first steel strand 7 are inserted in the conical through-hole of steel strand anchor slab 1, and wedge shape intermediate plate 3 is installed is carried out anchoring, dish spring 4, pressing plate 5 are installed then, and with screw 6 fixation clips 5; Make dish spring 4 dog wedge clevis sheets 3 through the screw 6 of screwing.At last the above-mentioned steel strand anchor slab 1 that installs steel strand 7 is screwed to the precalculated position from the two ends of connecting cylinder 2 respectively with finish rolling deformed bar 8, accomplish connection.
