[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-2 This utility model provides a technical solution for a steel structure anchor bolt positioning device:

[0024] Example 1:

[0025] according to Figure 1 and Figure 2 As shown, it includes two parallel guide rails 1 and at least two sliding rods 3. In this embodiment, there are three sliding rods 3. The number of sliding rods 3 can also be two, four or five. The specific number can be adjusted according to the actual construction needs. The guide rails 1 are made of square or rectangular tubes, and multiple positioning holes 11 are opened on the side of the guide rails 1.

[0026] At least two sliding parts 21 are provided on the guide rail 1. In this embodiment, three sliding parts 21 are provided on one guide rail 1. The specific number of sliding parts 21 is adjusted according to the number of sliding rods 3. The sliding part 21 is a U-shaped seat or a rectangular sliding sleeve. A threaded hole is opened on the side of the sliding part 21 near the positioning hole 11. The sliding part 21 can slide along the guide rail 1. A detachable positioning part is provided between the sliding part 21 and the guide rail 1. The positioning part is a positioning bolt 22. The end of the positioning bolt 22 passes through the threaded hole and is inserted into the corresponding positioning hole 11 to fix the position of the sliding part 21 after it moves, ensuring that the position of the sliding part 21 and the sliding rod 3 after they move is accurate and reliable.

[0027] The sliding rod 3 is positioned above the two guide rails 1, and its bottom is fixedly connected to the sliding component 21, allowing the sliding rod 3 to move with the sliding component 21. A reserved hole 31 for inserting the anchor bolt 6 is provided in the middle of the sliding rod 3, and mounting sleeves 5 for inserting the anchor bolt 6 are provided at both ends of the sliding rod 3. The reserved hole 31 in the middle of the sliding rod 3 and the mounting sleeves 5 at both ends provide precise positioning for the insertion of the anchor bolt 6, ensuring the installation accuracy of the anchor bolt 6.

[0028] In practical use, the steel structure anchor bolt positioning device of this utility model first slides the sliding rod 3 one by one according to the number and arrangement of the anchor bolts 6 in the foundation construction, adjusts the position of the sliding rod 3, and after adjusting the sliding rod 3 to a suitable position, the end of the positioning bolt 22 passes through the threaded hole and is inserted into the corresponding positioning hole 11 to fix the position of the sliding part 21 and the sliding rod 3 after movement.

[0029] Then, place the two guide rails 1 on top of the foundation outer formwork 7, and use fasteners to temporarily fix the guide rails 1 to prevent them from shifting. Then, for the anchor bolts 6 that need to be inserted into the reserved holes 31, insert the anchor bolts 6 into the reserved holes 31, insert the anchor bolts 6 into the mounting sleeves 5, and fix the anchor bolts 6.

[0030] Finally, the foundation concrete is poured. After the concrete has initially set, the device is removed for subsequent use.

[0031] Example 2:

[0032] Based on Example 1, the differences are as follows: Figure 1 As shown, the sliding rod 3 has a hollow interior, with fixing nuts 32 installed at both ends. The fixing nuts 32 are internally threaded with threaded rods 4. One end of the threaded rod 4 is fixedly connected to the mounting sleeve 5. By rotating the threaded rod 4, the position of the mounting sleeve 5 can be precisely adjusted to meet the installation requirements of the anchor bolts 6 in the foundation project, further improving the applicability of the device.
