Description

Technical Field

[0001] The utility model relates to the technical field of support engineering construction, in particular to an anchor rod fastening and positioning device. Background Technique

[0002] An anchor rod is a support structure that anchors a rod body (usually made of steel, such as steel bars, steel strands or steel pipes) deep into the ground through drilling, and injects a bonding material (such as cement slurry, mortar or resin) into the hole to enhance the bonding force between the rod body and the surrounding rock and soil mass. By closely combining the anchor rod with the rock and soil mass, the unstable bedding, joints or weak surfaces of the rock and soil mass are reinforced, and its integrity and stability are improved.

[0003] During the construction process of the anchor rod, when it comes to the support at the top arch of the tunnel, positioning steel bars are mainly used to fix and center the anchor rod. However, due to certain processing errors of the positioning steel bars and insufficient close fitting of the hole wall, the anchor rod may be skewed to a certain extent. Moreover, during the construction process, the processing of the positioning steel bars places certain requirements on the on-site construction workers, which also has an adverse impact on the project progress and on-site management. Based on this, the utility model designs an anchor rod fastening and positioning device to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide an anchor rod fastening and positioning device, which solves the problems of processing errors and inconvenient operation in the background technique.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0006] An anchor rod fastening and positioning device includes a connecting seat. The connecting seat has a cylindrical structure, and through holes are provided on the outer wall of the connecting seat. The through holes are distributed in a multi-group circumferential array. A fixing seat is installed on one side of the connecting seat, and a fixing claw is installed on one side of the fixing seat. The fixing seats and the fixing claws are distributed in a multi-group circumferential array.

[0007] Preferably, the inner diameter of the connecting seat matches the outer diameter of the anchor rod fixed inside, and the connecting seat is installed at different positions of the anchor rod according to the length of the anchor rod.

[0008] As the core component, the connecting seat is designed as a cylindrical structure, and its inner diameter matches the outer diameter of the anchor rod to ensure that it can be tightly sleeved on the anchor rod. The through holes provided on the outer wall of the connecting seat and the circumferentially arrayed fixing seats and fixing claws facilitate the movement and fixation of the connecting seat. This device is produced by a prefabrication method and can be customized according to the diameter and length of the anchor rod to meet the requirements of different specifications and lengths of anchor rods. This design enables the device to be prepared according to the design requirements before construction, improving the construction efficiency and accuracy.

[0009] Preferably, a groove is formed on the outer wall of the connecting seat, and a cable tie is installed in the inner cavity of the groove. The groove and the cable tie are respectively located at the top and bottom of the connecting seat.

[0010] By using cable ties in these grooves, further fastening of the anchor rod can be achieved, ensuring a tight fit between the device and the anchor rod. This design utilizes common materials at the construction site, reducing costs while improving the fastening effect. The cable tie is wound around the groove and the anchor rod, and by using the elasticity and tension of the cable tie, the connecting seat is firmly fixed to the anchor rod.

[0011] Preferably, a threaded hole is formed on the outer wall of the connecting seat, and a threaded rod is threadedly connected in the inner cavity of the threaded hole. A handle is installed on one side of the threaded rod, and a fixing plate is installed on the side of the threaded rod located in the inner cavity of the connecting seat.

[0012] The design of the threaded rod enables the device to adapt to anchor rods of different diameters and enhances the fastening effect by screwing tight.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-3 , an anchor rod fastening and positioning device, comprising a connecting seat 1. The connecting seat 1 is of a cylindrical structure, and through holes 2 are provided on the outer wall of the connecting seat 1. The through holes 2 are distributed in a multi-group circumferential array. A fixed seat 3 is installed on one side of the connecting seat 1, and a fixed claw 4 is installed on one side of the fixed seat 3. The fixed seat 3 and the fixed claw 4 are distributed in a multi-group circumferential array. The inner diameter of the connecting seat 1 matches the outer diameter of the anchor rod fixed inside, and the connecting seat 1 is installed at different positions of the anchor rod according to the length of the anchor rod.

[0023] In the embodiment of the present invention, as the core component, the connecting seat 1 is designed as a cylindrical structure, and its inner diameter matches the outer diameter of the anchor rod to ensure that it can be tightly sleeved on the anchor rod. The through holes 2 provided on the outer wall of the connecting seat 1 and the fixed seats 3 and fixed claws 4 distributed in a circumferential array facilitate the movement and fixation of the connecting seat 1.

[0024] The device is produced by a prefabrication method and can be customized according to the diameter and length of the anchor rod to meet the requirements of anchor rods of different specifications and lengths. This design enables the device to be prepared according to the design requirements before construction, improving the construction efficiency and accuracy.

[0025] Please refer to Figures 1-4 , grooves 5 are provided on the outer wall of the connecting seat 1, cable ties 6 are installed in the inner cavities of the grooves 5, the grooves 5 and the cable ties 6 are respectively located at the top and bottom of the connecting seat 1, threaded holes 7 are provided on the outer wall of the connecting seat 1, threaded rods 8 are threadedly connected in the inner cavities of the threaded holes 7, handles 9 are installed on one side of the threaded rods 8, and fixed plates 10 are installed on one side of the threaded rods 8 located in the inner cavity of the connecting seat 1.

[0026] In the embodiment of the present utility model, the groove 5 formed on the outer wall of the connecting seat 1 provides an installation position for the cable tie 6. By installing the cable tie 6 in these grooves 5, further fastening of the anchor bolt can be achieved, ensuring a tight fit between the device and the anchor bolt. This design utilizes common materials at the construction site, reducing costs while improving the fastening effect. The cable tie 6 is wound around the groove 5 and the anchor bolt, and by using the elasticity and tension of the cable tie 6, the connecting seat 1 is firmly fixed to the anchor bolt. This fastening method is not only simple and fast but also can effectively resist the displacement or loosening that the anchor bolt may generate in the hole, ensuring the stability of the anchor bolt before the mortar solidifies.

[0027] During the installation of the anchor bolt, the setting of the fastening cable tie 6 is carried out synchronously with the installation of the anchor bolt. In this way, as the anchor bolt gradually penetrates into the hole wall, the fastening cable tie 6 also tightens accordingly, further enhancing the fastening effect between the anchor bolt and the hole wall.

[0028] The threaded hole 7 formed on the outer wall of the connecting seat 1 allows the threaded rod 8 to be screwed in. By rotating the handle 9, the position of the threaded rod 8 in the hole can be conveniently adjusted. The design of the threaded rod 8 enables the device to adapt to anchor bolts of different diameters and enhances the fastening effect by screwing tightly. A fixing plate 10 is installed on one side of the threaded rod 8 located in the inner cavity of the connecting seat 1. When the threaded rod 8 is screwed tightly, the fixing plate 10 will closely adhere to the surface of the anchor bolt, further increasing the friction between the device and the anchor bolt and improving the fastening effect. At the same time, the fixing plate 10 can also play a role in centering the anchor bolt to ensure that the anchor bolt maintains the correct position in the hole.

[0029] When in use, before installing the anchor bolt, first put the prefabricated tight fixing and positioning device on a specific position of the anchor bolt, and then tightly fit the device and the anchor bolt through the cable tie 6. As the anchor bolt is sent into the hole, the fastening effects of the cable tie 6 and the threaded rod 8 will ensure a stable connection between the device and the anchor bolt. Through its unique structural design, the device realizes multi-point support, fastening, and centering of the anchor bolt, preventing the displacement or loosening of the anchor bolt in the hole, helping to ensure the firm fixation of the anchor bolt before the mortar solidifies, and ensuring that the thickness of the mortar protective layer is uniform, thereby improving the overall quality of the anchor bolt support. At the same time, the use of the device also improves the speed and quality of the anchor bolt support, ensuring the thickness of the mortar protective layer and the overall effect of the anchor bolt support.

[0030] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirits. The scope of the present utility model is defined by the appended claims and their equivalents.
