Description

Technical Field

[0001] This utility model relates to the field of steel structure installation technology, specifically to the installation structure of pre-embedded anchor bolts in steel structure foundations. Background Technology

[0002] Anchor bolts are special bolts used to fix equipment, structures, etc. to a foundation. Usually, one end is embedded in the concrete foundation, and the other end is connected to the equipment or structure through a nut. Traditionally, anchor bolts are positioned by pre-embedded parts. Each time, two positioning blocks need to be accurately placed at the bottom of the pre-embedded parts, and then they are placed on the template to complete a series of operations such as concrete pouring, removal of pre-embedded parts and positioning blocks.

[0003] Traditional anchor bolt installation relies on simple positioning methods and lacks effective means to enhance the stability of the bolt installation location. Typically, the anchor bolts are simply placed on pre-embedded parts before concrete pouring. During concrete pouring, the anchor bolts are prone to displacement due to concrete flow and vibration. Therefore, we propose a pre-embedded anchor bolt installation structure for steel structure foundations. Utility Model Content

[0004] The purpose of this utility model is to provide a pre-embedded anchor bolt installation structure for steel structure foundations to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a steel structure foundation pre-embedded anchor bolt installation structure, including pre-embedded parts and a bracket installed at the top center of the pre-embedded parts;

[0006] The bracket has a bidirectional lead screw that extends to the outer end of the bracket and is rotatably connected inside. Both ends of the bidirectional lead screw are threaded with threaded sleeves. The bottom end of each threaded sleeve is provided with a connecting rod. Both sides of the connecting rod are fixedly connected with clamping plates. One end of each clamping plate is provided with a U-shaped fixing hole. The bottom end of each clamping plate is fixedly connected with a sliding rod. The top of each embedded part is provided with a guide groove with a diameter matching that of the sliding rod near the bottom of the clamping plate.

[0007] Preferably, bolt holes are provided at all four corners of the embedded part, and anchor bolts are installed inside the bolt holes. The lower end of the anchor bolt is threaded with a first nut, and the upper end of the anchor bolt is threaded with a second nut. A nut washer matching the U-shaped fixing hole is provided near the lower end of the second nut of each anchor bolt.

[0008] Preferably, each threaded sleeve has a slider fixedly connected to its top end, and the bracket has a groove at its top end, with the slider being engaged in the groove.

[0009] Preferably, the two outer walls of the embedded part are provided with recesses, and the inner walls of the recesses are provided with spirit levels.

[0010] Preferably, a handle is fixedly connected to one end of the bidirectional lead screw.

[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows: During installation, the nut washer is aligned with the U-shaped fixing hole, and the double-acting screw is rotated to move the clamping plate, which clamps and holds the nut washer through the U-shaped fixing hole, further stabilizing the bolt installation area. This design enhances the stability of anchor bolt installation, reduces the risk of anchor bolt displacement during construction processes such as concrete pouring, ensures the connection strength between the anchor bolt and the embedded parts, and guarantees the stability of the steel structure foundation.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4 The present invention provides the following technical solution:

[0019] Example 1: Steel structure foundation pre-embedded anchor bolt installation structure, including pre-embedded part 1 and bracket 2 installed at the top center of pre-embedded part 1. Bolt holes 103 are opened at the four corners of pre-embedded part 1. Anchor bolts 12 are installed inside the bolt holes 103. The lower end of the anchor bolt 12 is threaded with a first nut 13. The upper end of the anchor bolt 12 is threaded with a second nut 14. The lower end of the anchor bolt 12 near the second nut 14 is provided with a nut washer 15 that matches the U-shaped fixing hole 202. The two outer walls of pre-embedded part 1 are provided with recesses 102. The inner wall of the recesses 102 is provided with a level 11.

[0020] In use, firstly, rotate the first nut 13 and the second nut 14 respectively to fix the embedded part 1 to the four anchor bolts 12 through the nut washer 15. Then, place the two positioning blocks on the two templates, and then place the embedded part 1 on the upper end. Pour concrete into the template and the lower end of the embedded part 1. Stop when the concrete is close to the embedded part 1. Then rotate the second nut 14 to remove the nut washer 15 and the embedded part 1 respectively. Then, use two levels 11 to observe whether the embedded part 1 is in a horizontal position and make further adjustments.

[0021] Example 2: The technical solution of this example, which differs from that of Example 1, includes: a bidirectional lead screw 21 extending to the outer end of the bracket 2 is rotatably connected through the inside of the bracket 2. Both ends of the bidirectional lead screw 21 are threadedly connected to threaded sleeves 22. Each threaded sleeve 22 has a connecting rod 24 at its bottom end. Both sides of the connecting rod 24 are fixedly connected to clamping plates 25. Each clamping plate 25 has a U-shaped fixing hole 202 through one end. Each clamping plate 25 has a sliding rod 26 fixedly connected to its bottom end. Each embedded part 1 has a guide groove 101 with a diameter matching that of the sliding rod 26 near the bottom end of the clamping plate 25. Each threaded sleeve 22 has a slider 23 fixedly connected to its top end. Each bracket 2 has a sliding groove 201 at its top end, and the slider 23 is locked in the sliding groove 201. One end of the bidirectional lead screw 21 is fixedly connected to a handle.

[0022] In use, the operator first aligns the nut washer 15 with its U-shaped fixing hole 202, and then rotates the handle to drive the double-acting screw 21 to rotate. The rotation of the double-acting screw 21 will drive the threaded sleeve 22 to move. The threaded sleeve 22 will slide along the slide groove 201 through the slider 23. At this time, the threaded sleeve 22 will drive the clamping plate 25 to move outward through the connecting rod 24, and clamp the nut washer 15 outward through the U-shaped fixing hole 202 and hold it against it, thereby further stabilizing the bolt installation part.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
