During the construction operations such as concrete pouring or vibration after the anchor bolts are pre-fixed, it is very easy to cause disturbances, resulting in the change of the fixed position of the anchor bolts, and thus affecting the subsequent docking of the anchor bolts with the fixed nuts in the building after the concrete pouring is completed. For this reason, we propose a fixing device for embedded anchor bolts. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0018] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the present utility model provides a technical solution: A fixing device for embedded anchor bolts, including a fixing plate 1. An installation hole 2 is opened in the fixing plate 1. The installation hole 2 is used for the assembly of the anchor bolt 8. A fixing nut 9 is screwed on the outer side wall of the anchor bolt 8 to limit and fix the relative positions of the fixing plate 1 and the anchor bolt 8.

[0019] The surface of the fixing plate 1 is provided with assembly holes 3. Every two assembly holes 3 form a group, and each group of assembly holes 3 is axially symmetrically distributed with the mounting hole 2 as the center. A fixing mechanism 4 is assembled in each group of assembly holes 3. The provided fixing mechanism 4 is used to assist in fixing the anchor bolt 8, increasing the stability between the anchor bolt 8 and the fixing plate 1 during the concrete pouring and vibration processes, and maintaining the accuracy and stability of the connection position between the anchor bolt 8 and the fixing plate 1.

[0020] As Figure 3 shown in the figure, the fixing mechanism 4 includes a fixing sleeve 41. A fixing groove 42 adapted to the size of the anchor bolt 8 is provided at the center of the fixing sleeve 41. The top end of the anchor bolt 8 is limited by the fixing groove 42. Fixing blocks 43 are respectively welded and fixed to the left and right side walls of the fixing sleeve 41. The number of fixing blocks 43 on each side is two, and the two fixing blocks 43 are symmetrically distributed up and down with the center of the fixing sleeve 41 as the center. Rotating shafts 44 are respectively rotatably connected in the fixing blocks 43 on both sides. Fixing studs 45 are respectively welded and fixed to the bottom parts of the rotating shafts 44 on both sides. After the fixing studs 45 are screwed with the assembly holes 3, the positions of the rotating shafts 44 are fixed. By setting the correspondingly distributed fixing blocks 43, the position of the fixing sleeve 41 can be fully fixed from both sides through the rotating shafts 44, strengthening the stability of the fixing sleeve 41 in fixing the anchor bolt 8.

[0021] Handle blocks 46 are integrally formed at the top parts of the rotating shafts 44. By setting the handle blocks 46, it is convenient to rotate the rotating shafts 44.

[0022] As Figure 3 shown in the figure, an assembly groove 5 is provided on the side wall of the fixing groove 42 in the middle of the fixing sleeve 41. A rubber sleeve 6 is clamped in the assembly groove 5. By adding a rubber sleeve 6 between the fixing sleeve 41 and the anchor bolt 8, the buffering performance between the fixing sleeve 41 and the anchor bolt 8 is enhanced, and the stability of the fixation between the anchor bolt 8 and the fixing plate 1 can be better increased.

[0023] As Figure 2 shown in the figure, a rubber pad 7 is sleeved on the outer side wall of the fixing stud 45. By setting the rubber pad 7, the connection between the rotating shaft 44 and the assembly hole 3 is buffered, strengthening the stability of the connection and fixation among the rotating shaft 44, the fixing stud 45 and the assembly hole 3.

[0024] As Figure 1 and Figure 4 shown in the figure, the fixing plate 1 can be rectangular or circular, and the specific shape can be specifically set according to the construction requirements.

[0025] Working principle: During the use of this device, first, according to the construction requirements, the anchor bolt 8 is connected to the mounting hole 2 of the fixing plate 1, and then the position of the anchor bolt 8 and the fixing plate 1 is fixed by the fixing nut 9. After the anchor bolt 8 is connected and fixed, the fixing sleeve 41 of the fixing mechanism 4 is sleeved on the outer wall of the anchor bolt 8, and the bottoms of the rotating shafts 44 on both sides are inserted into the assembly holes 3. The rotating shafts 44 are screwed by the handle block 46 to connect and fix the fixing studs 45 with the assembly holes 3, so that the fixing sleeve 41 limits and fixes the anchor bolt 8. During the process of pouring and vibrating the concrete, the fixing sleeve 41 can fully maintain the stability of the fixed position of the anchor bolt 8. After the concrete pouring is completed, the fixing sleeve 41 can be disassembled and reused later.
