Anti-floating anchor rods are needed in the construction process of high-rise buildings. Anti-floating anchor rods include anchor heads, anchor rod bodies, grouting plugs and pads. When in use, first measure and place the hole, then use a drill to drill the hole, clean the drill hole, align the anchor head of the anchor rod with the hole, put it into the hole, and grouting is carried out. However, in order to ensure the stability and firmness of the pile during the grouting process, a grouting machine needs to be used to repeatedly add grout, which greatly increases the workload. In addition, during the placement of the anchor rod, the diameter of the anchor rod is fixed. When placed in the hole, it is often impossible to accurately locate at the center of the hole, causing the slurry to be unevenly distributed around the anchor rod, reducing the stability of the pile. Therefore, the existing technology needs further improvement. Utility Model Content

DETAILED DESCRIPTION

[0023] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0024] like Figure 1-Figure 2 As shown, an anti-floating anchor rod that is easy to install includes an embedded part 1 and a positioning part 2. The embedded part 1 and the positioning part 2 are both annular. A plurality of fixing bolts 11 distributed in a circle are fixedly installed on the upper surface of the embedded part 1. The positioning part 2 is sleeved on the plurality of fixing bolts 11. A plurality of first positioning grooves 12 are provided on the opposite sides of the embedded part 1 and the positioning part 2. A plurality of second positioning grooves 21 corresponding to the first positioning grooves 12 are provided on the side of the positioning part 2 relative to the embedded part 1. A plurality of through grooves 22 are also provided inside the positioning part 2. Anchor rods 3 are inserted into the interiors of the embedded part 1 and the positioning part 2.

[0025] like Figure 1-Figure 4 As shown, a plurality of first positioning rods 31 and a second positioning rod 32 are fixedly installed on the outer surface of the anchor rod 3, and the plurality of first positioning rods 31 and the second positioning rod 32 are evenly distributed in a staggered manner on the circumference. The plurality of first positioning rods 31 enter the inner walls of the embedded part 1 and the positioning part 2 and abut against their inner circumferential walls to perform preliminary positioning of the anchor rod 3, and the plurality of second positioning rods 32 respectively enter between the embedded part 1 and the positioning part 2 from the plurality of through grooves 22. The anchor rod 3 is rotated to make the second positioning rod 32 enter the inside of the first positioning groove 12. At this time, the positioning part 2 is pressed down to make the second positioning rod 32 located outside the first positioning groove 12 enter the inside of the second positioning groove 21, and then the sealing cover plate 4 is sleeved on the plurality of fixing bolts 11. Finally, the fixing part 13 is threadedly installed on the end of the fixing bolt 11. The fixing part 13 abuts against the upper surface of the sealing cover plate 4. The outer surface of the fixing part 13 is fixedly installed with a plurality of connecting strips 131 for rotating it, which can facilitate the user to install and disassemble it by hand.

[0026] like Figure 5-Figure 6As shown, a plurality of mounting holes 14 are provided inside the embedded part 1, and each mounting hole 14 is connected to one side of a first positioning groove 12 respectively. The positioning part 2 is inserted into the interior of the mounting hole 14 through the connecting plate 23. The connecting plate 23 is also used to limit the second positioning rod 32. When the second positioning rod 32 cannot rotate, it is located inside the first positioning groove 12, so that the user can install and fix the anchor rod 3 to avoid the anchor rod 3 floating. In order to prevent the connecting plate 23 from falling off from the inside of the mounting hole 14, a limiting ring 24 is also provided at the bottom of the plurality of connecting plates 23.

[0027] During use, first install the embedded part 1 at the anchor hole, install the positioning part 2 on multiple fixing bolts 11 of the embedded part 1, and then install the anchor rod 3 at the center hole of the embedded part 1 and the positioning part 2. The first positioning rod 31 of the anchor rod 3 enters the inner wall of the center hole of the embedded part 1 and the positioning part 2 and abuts against its inner circumferential wall. The second positioning rod 32 of the anchor rod 3 enters between the embedded part 1 and the positioning part 2 through the through groove 22. The anchor rod 3 is rotated so that the second positioning rod 32 enters the inside of the first positioning groove 12 and the second positioning groove 21, and the positioning part 2 is preliminarily fixed using the fixing part 13. Then, the anchor hole is grouted twice by inserting a grouting pipe into the through groove 22 (the first grouting is normal pressure grouting, using the bottom grouting method, and the second grouting is carried out 24 hours after the first grouting. The second grouting is high-pressure grouting, and the slurry is pure cement slurry). After the grouting is completed, the fixing part 13 is loosened to install the sealing cover plate 4.

[0028] In the present invention, an embedded part 1 is provided, a fixing bolt 11 is provided on the embedded part 1 to install the positioning part 2, a first positioning rod 31 and a second positioning rod 32 are evenly distributed on the outer surface of the anchor rod 3, and a first positioning groove 12 and a second positioning groove 21 are opened on the opposite sides of the embedded part 1 and the positioning part 2. The first positioning rod 31 can be installed at the center of the embedded part 1 and the positioning part 2 to preliminarily position the anchor rod 3, so that the second positioning rod 32 passes through the through groove 22 on the positioning part 2 and enters between the embedded part 1 and the positioning part 2. The anchor rod 3 is rotated so that the second positioning rod 32 enters the inside of the first positioning groove 12 and the second positioning groove 21, and the fixing part 13 is used to install and fix the positioning part 2 to position the anchor rod 3, thereby achieving the purpose of preventing the anchor rod 3 from floating.
