The utility model discloses the technical scheme who further injects is:

further, the inner wall of the anchoring cylinder sleeve mainly consists of: the steel strand anchoring fixture comprises a thread section with the same diameter and a smooth reducing section, wherein the reducing end of the anchoring cylinder sleeve and the steel strand anchoring fixture are fixed in a matched mode through conical surfaces, after the steel strand anchoring fixture is pressed into the anchoring cylinder sleeve, the steel strand anchoring fixture deforms to clamp the steel strand, and the small-diameter end of the steel strand anchoring fixture extends out of an opening of the reducing section of the anchoring cylinder sleeve by a certain length.

Furthermore, the diameter of the large-diameter end of the steel strand anchoring clamp is smaller than the inner diameter of the thread section of the anchoring cylinder sleeve, the outer thread section of the thread sleeve is matched with the thread section of the anchoring cylinder sleeve, and a section of thread used for screwing the thread sleeve is preprocessed at the end part of the common steel bar.

Furthermore, the steel strand anchoring fixture is formed by encircling a plurality of sub-clamping pieces, a plurality of sub-clamping pieces are gathered together and encircled on the prestressed steel strand, and are pushed into the anchoring cylinder sleeve through a tool, inner rings of the sub-clamping pieces abut against the prestressed steel strand to form an axial friction positioning structure, one end of the spring abuts against the end part of the sub-clamping piece, and the other end of the spring abuts against the end surface of the threaded sleeve.

Furthermore, the other end of the spring is abutted against the end face of the threaded sleeve through a gasket.

Further, the outer diameter of the washer is substantially identical to the outer diameter of the spring

The utility model has the advantages that: the utility model discloses a attach fitting has accomplished being connected of prestressing force steel strand wires and ordinary reinforcing bar through anchor clamps and threaded connection, has both avoided prestressing force reinforcing bar can not welded material performance problem, has also realized the material of two kinds of different materials in connection stability's reliability.

Detailed Description

Example 1

The patent of the utility model contains a prestressing force steel strand and ordinary steel bar connection joint by 01 prestressing force steel strand, 02 anchor cylinder liner, 03 steel strand anchoring anchor clamps, 04 spring, 05 gasket, 06 threaded sleeve, 07 ordinary reinforcing bar, 7 parts are constituteed. As shown in fig. 01.

In operation, the 01 prestressed steel strand is fixed in the 02 anchoring cylinder sleeve by the 03 steel strand anchoring clamp, as shown in fig. 02. Next, the 04 spring is placed 02 in the rear half of the anchor cylinder as shown in fig. 03 and 04. A05 gasket is placed into the 02 anchoring cylinder sleeve to support 04 the spring. As shown in figure 05. The inside of the rear half section of the 02 anchoring cylinder sleeve is provided with a thread, the outside of the front half section of the 06 sleeve with the thread is provided with a thread, and the inside of the rear half section is provided with a thread. 07 the common steel bar is connected with the second half section of the 06 sleeve with screw thread through screw thread, as shown in figures 05 and 06. And finally, the 06 threaded sleeve is in threaded connection with the rear half section of the 02 anchoring cylinder sleeve through the front half section. Because the 04 spring and the 05 gasket are arranged in the 02 anchoring cylinder sleeve, the 03 steel strand anchoring fixture can be prevented from loosening, and the connection stability of the 01 prestressed steel strand and the 02 anchoring cylinder sleeve is ensured.

As shown in fig. 08-12, the 03 steel strand anchoring fixture is formed by surrounding a plurality of 03.1 split clamping pieces, the 03.1 split clamping pieces are mutually gathered and surrounded on a 01 prestressed steel strand and pushed into a 02 anchoring sleeve cylinder through a tool, inner rings of the 03.1 split clamping pieces are abutted against the 01 prestressed steel strand to form an axial friction positioning structure, one end of a 04 spring is abutted against the end part of the 03.1 split clamping piece, and the other end of the 04 spring is abutted against the end surface of a 06 threaded sleeve through a 05 gasket.
