Description

Technical Field

[0001] This utility model relates to the field of construction tools, and in particular to a soil nail centering bracket processing device. Background Technology

[0002] Soil nail centering support is a device used in foundation pit support engineering to ensure that the soil nails are centered in the soil nail holes.

[0003] The soil nail centering bracket is used to ensure that the soil nail is located in the center of the soil nail hole, so that the protective layer around the soil nail is of uniform thickness, thereby improving the bonding force and friction between the soil nail and the soil, enhancing the pull-out resistance of the soil nail, and effectively exerting the reinforcement effect of the soil nail on the slope soil; it also makes the grouting process smoother, ensuring that the grout can be evenly filled around the soil nail to form a good consolidation body, improving the grouting effect, and enhancing the consolidation strength between the soil nail and the soil.

[0004] Currently, soil nailing centering supports are typically formed by bending steel bars using a steel bar bending machine. This processing method requires multiple bends to form a U-shaped centering support structure, which is a complex process with low efficiency. Furthermore, the processing accuracy depends heavily on the operator's experience, which can easily lead to inconsistent quality in the centering support processing. This method needs improvement.

[0016] Example 1, see appendix Figure 1-5A soil nail centering support processing device includes a fixed support 01 and a rotating support 02. The fixed support is generally square in shape. The fixed support 01 includes two side rods 11 and an end rod 12 connected between the outer ends of the two side rods. The inner side of the end of the side rod 11 is provided with a vertical inner stop rod 13, and the outer side of the end is provided with a vertical outer stop rod 14. The vertical inner stop rod and the vertical outer stop rod 14 on the side rod 11 are arranged alternately, so that a gap is formed between the vertical inner stop rod 13 and the vertical outer stop rod 14 for inserting a steel bar 25. The two ends of the steel bar are respectively inserted into the gaps on both sides.

[0017] One end of the rotating bracket 02 is hinged to one end rod 12 between the two side rods 11. Two top pressure rods 21 are arranged side by side in the middle of the rotating bracket 02. The two top pressure rods are close to the vertical inner support rods 13 on both sides. A large gap is formed between the top pressure rods 21 and the vertical inner support rods, which matches the size of the steel bar 25. This gap is used to accommodate the bent section of the steel bar 25 after it is bent. The other end of the rotating bracket 02 is provided with a handle 22.

[0018] The grip 22 is connected to the rotating bracket 02 in an upward tilted state. Reinforcing rods 24 are provided on both sides of the connection between the grip 22 and the rotating bracket 02 to improve the connection strength of the grip 22 on the rotating bracket 02.

[0019] A cylindrical pad 18 is provided in the gap between the vertical inner stop bar 13 and the vertical outer stop bar 14. The cylindrical pad 18 supports the steel bar 25 and prevents the friction generated by the steel bar 25 from damaging the side bar 11 of the fixed bracket 01. The cylindrical pad 18 can be replaced when it is severely worn.

[0020] The usage method and principle of this embodiment are as follows: Cut a fixed length of steel bar 25 according to the length of the centering bracket, then hold the handle 22 and lift the rotating bracket 02 upwards, so that the large top pressure rod 21 on the rotating bracket 02 is offset outwards from the vertical inner stop rod 13 and the vertical outer stop rod 14 on both sides. Place the steel bar 25 horizontally at the end of the fixed bracket 01, and insert the end of the steel bar 25 into the gap between the vertical inner stop rod 13 and the vertical outer stop rod 14. Then hold the handle 22 and press the rotating bracket 02 downwards. By rotating and pressing the rotating bracket 02, the lever pressure can be used to bend the middle part of the top pressure rod 21. The two ends of the steel bar 25 remain straight under the action of the clamping force, forming a U-shaped bending structure. The centering bracket can be formed by pressing once, without repeated bending, which can ensure the processing quality and the processing operation is simple.

[0021] Example 2, see appendix Figure 1-2This embodiment is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that the end rod 12 is a cylindrical rod, and the end of the rotating bracket 02 is provided with a long shaft sleeve 23. The long shaft sleeve 23 is rotatably mounted on the cylindrical rod. The length of the long shaft sleeve 23 is the same as the length of the end rod 12 between the two side rods 11, so as to keep the rotating bracket 02 in the middle position of the fixed bracket 01, thereby ensuring the machining accuracy of the central bracket.

[0022] The inner diameter of the long bushing 23 is larger than the diameter of the cylindrical rod. A bearing is installed between the ends of the cylindrical rod and the long bushing 23. The bearing reduces the rotational friction between the rotating bracket 02 and the fixed bracket 01, making operation easier.

[0023] Example 3, see appendix Figure 1 This embodiment is basically the same as the first embodiment, and the similarities will not be repeated. The difference is that the four corners of the fixed bracket 01 are provided with support legs 15, and the two support legs 15 at the ends of the fixed bracket 01 are arranged in a figure-eight shape. By setting support legs 15 on the fixed bracket 01, it is supported to a certain height so that it matches the height of the processing personnel, so that they do not have to bend over repeatedly for processing, which helps to improve the comfort of operation.

[0024] The V-shaped support leg 15 structure helps to improve the support stability of the processing device. At the same time, a horizontal support rod 16 is provided between the two support legs 15 at the end of the fixed bracket 01, and a longitudinal support rod 17 is provided between the two horizontal support rods 24. The horizontal support rod 16 and the longitudinal support rod 17 form a reinforced support structure between the support legs 15.
