[0021] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0022] First embodiment

[0023] Please refer to Figure 1-5 The bolt connection structure for steel structure engineering comprises a head 1, a rod 2 and a nut 4, wherein the rod 2 and the head 1 are fixedly connected, and the nut 4 is spirally connected to the rod 2. Through holes 7 are provided on the surfaces of the head 1 and the rod 2, and the two through holes 7 are connected through each other. The inner wall of the through hole 7 is provided with an internal thread, and a threaded column 10 is spirally connected inside the through hole 7. A fixing column 12 is provided at one end of the threaded column 10, and a circular slide rail 11 is provided on the side surface of the fixing column 12, and an arc-shaped slider is slidably connected inside the circular slide rail 11, and a limit rod 5 is provided at one end of the arc-shaped slider.

[0024] By setting the through hole 7, internal thread, threaded column 10, fixed column 12, circular slide rail 11, and arc-shaped slider for use together, it is convenient to improve the stability between the nut 4 and the rod 2 after the bolt is fixed to the steel structure. After the spiral is fixed to the steel structure and the nut 4 is spirally screwed to the rod 2, the staff screws the threaded column 10 into the through hole 7, so that when the threaded column 10 moves inside the through hole 7, it drives the rotating column 9 to move inside the slide rail 6, so that the fixed column 12 contacts one end of the nut 4, thereby greatly improving the stability of the nut 4 and the rod 2 under the limitation of the fixed column 12, and avoiding the phenomenon of thread slippage.

[0025] The working principle of the bolt connection structure for steel structure engineering provided by the utility model is as follows:

[0026] After the spiral is fixed to the steel structure and the nut 4 is screwed with the rod 2, the staff screws the threaded column 10 into the through hole 7, so that when the threaded column 10 moves inside the through hole 7, it drives the rotating column 9 to move inside the slide 6, so that the fixed column 12 contacts one end of the nut 4, thereby greatly improving the stability of the nut 4 and the rod 2 under the limitation of the fixed column 12, and avoiding the phenomenon of thread slippage. By setting the limiting plate 3 and the rotating column 9, when the nut 4 is connected to the rod 2, the staff can drive the limiting plate 3 to rotate through the rotating column 9, thereby quickly driving the nut 4 to be combined with the rod 2.

[0027] Compared with the related art, the bolt connection structure for steel structure engineering provided by the utility model has the following beneficial effects:

[0028] By setting the through hole 7, internal thread, threaded column 10, fixed column 12, circular slide rail 11, and arc-shaped slider for use, it is convenient to improve the stability between the nut 4 and the rod 2 after the bolt fixes the steel structure. After the spiral is fixed to the steel structure and the nut 4 is spirally connected to the rod 2, the staff screws the threaded column 10 into the through hole 7, so that when the threaded column 10 moves inside the through hole 7, it drives the rotating column 9 to move inside the slide rail 6, so that the fixed column 12 contacts one end of the nut 4, thereby greatly improving the stability of the nut 4 and the rod 2 under the limitation of the fixed column 12, and avoiding the phenomenon of thread slippage. By setting the limit plate 3 and the rotating column 9, when the nut 4 is connected to the rod 2, the staff can drive the limit plate 3 to rotate through the rotating column 9, thereby quickly driving the nut 4 to be combined with the rod 2.
