DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] In order to facilitate the stable positioning of the steel bars when they are tightened, the limiting structure is not easily damaged when the steel bars are tightened, thereby improving the reliability during use. Figure 1-4 As shown, the anchor described in the utility model includes a disc-shaped block 1, a boss 2 and a steel bar routing groove 17. The boss 2 is provided at the bottom of the disc-shaped block 1, and the bottom of the boss 2 is provided with a steel bar routing groove 17. The top of the steel bar routing groove 17 passes through the top of the disc-shaped block 1;

[0024] The top of the disc-shaped block 1 is fixed with a connecting plate 5 near the outer side of the edge of the steel bar wiring groove 17 by a connecting bolt 4. A fixing sleeve 11 is provided near the center of the top of the connecting plate 5. The top of the fixing sleeve 11 is connected to the limiting groove 6. The upper plate body 7 is sleeved in the limiting groove 6. The bottom of the upper plate body 7 is connected to the lower plate body 10 through a connecting column 9. The bottom of the lower plate body 10 is connected to a wiring sleeve 12 near the center. The wiring sleeve 12 is located in the fixing sleeve 11. The tops of the upper plate body 7 and the lower plate body 10 are respectively penetrated by a first wiring hole 8 and a second wiring hole 13.

[0025] When in use, one end of the steel bar is connected to the wire rope, which is made of multiple strands of thin steel wires. The thin steel wires pass through the first wiring hole 8 and the second wiring hole 13 in turn, and are staggered when passing through. After passing through the second wiring hole 13, the thin steel wires are re-twisted into thicker wire ropes in the wiring sleeve 12, and then connected to the steel bar passing through the steel bar wiring groove 17. When the steel bar is tightened, the limiting effect of the limiting groove 6 on the upper plate body 7 and the lower plate body 10 can make this anchor have a stable limiting structure for the steel bar, which can effectively prevent the problem that the jacket is easily damaged when limiting by the jacket in the past, and the reliability during use is greatly improved.

[0026] For example, Figure 1 and Figure 4 As shown, the present invention further includes that the bottom end of the second wiring hole 13 is communicated with the wiring sleeve 12 .

[0027] During use, since the second wiring hole 13 is connected to the wiring sleeve 12 , the thin steel wire rope can be gathered in the wiring sleeve 12 after passing through the second wiring hole 13 and twisted into a thicker steel wire rope.

[0028] For example, Figure 1-3 As shown, the present invention also includes that the outer sides of the disc-shaped blocks 1 are each provided with a strip-shaped reserved groove 3 .

[0029] When in use, the strip-shaped reserved groove 3 can effectively increase the contact area between the external poured concrete and the anchor, thereby improving the fixing effect of the disc-shaped block 1 after pouring.

[0030] For example, Figure 1-3 As shown, the present invention further includes that a through groove 14 is formed through the boss 2 and the disc-shaped block 1 near the center.

[0031] When in use, the through groove 14 can effectively reduce the overall weight of the disc-shaped block 1 and the boss 2 .

[0032] For example, Figure 1-3 As shown, the present invention further includes that the inner wall of the through groove 14 is connected to a columnar block 15 via a connecting rod 16 .

[0033] When in use, the columnar block 15 and the connecting rod 16 can effectively improve the strength of the through slot 14 .

[0034] For example, Figure 1-3 As shown, the present invention also includes that the bottom edges of the disc-shaped block 1 and the boss 2 are both provided with chamfers 18 .

[0035] When in use, the chamfer 18 can effectively increase the contact area between the anchor and the concrete during concrete pouring, thereby effectively improving the stabilization effect of the anchor.

[0036] When the present invention is in use, one end of the steel bar is connected to the wire rope, which is made of multiple strands of thin steel wires. The thin steel wires pass through the first wiring hole 8 and the second wiring hole 13 in turn, and are staggered when passing through. After passing through the second wiring hole 13, the thin steel wires are re-twisted into thicker wire ropes in the wiring sleeve 12, and then connected to the steel bar passing through the steel bar wiring groove 17. When the steel bar is tightened, the limiting effect of the limiting groove 6 on the upper plate body 7 and the lower plate body 10 can make this anchor have a stable limiting structure for the steel bar, which can effectively prevent the problem that the jacket is easily damaged when limiting by the jacket in the past, and the reliability during use is greatly improved.
