[0001] This invention relates to the technical field of building construction, and in particular to an auxiliary device for pre-embedding bolts for steel structure columns. Background Technology

[0002] During steel structure construction, the correctness of the anchor bolt pre-embedded position and elevation directly determines whether the entire factory building can be used normally and its service life.

[0003] Steel structure columns are mostly connected to the reinforced concrete foundation using pre-embedded anchor bolts. The first step in steel structure construction is the pre-embedding of anchor bolts, so its construction quality and installation condition have a significant impact on the subsequent use of the steel structure. To ensure the quality of the later installation of the steel structure and meet the requirements of the project, it is necessary to ensure that the pre-embedded anchor bolts meet the specifications. Significant deviations in the installation of the anchor bolts will affect the installation of the superstructure, leading to difficulties in later construction. Summary of the Invention

[0013] The following is in conjunction with the appendix Figure 1 -Appendix Figure 3 The present invention will be described in further detail below.

[0014] Reference Figures 1-3 This invention discloses an auxiliary device for pre-embedding bolts for steel structure columns, comprising a lightweight guide rail, a steel bar connecting buckle 3, a positioning steel bar 4, a steel bar fixing clip 5, and a guide rail connector 6. The lightweight guide rail is located on top of the foundation template 10 and is arranged around the foundation template 10.

[0015] The lightweight guide rail includes a first lightweight guide rail 1 and a second lightweight guide rail 2. The two first lightweight guide rails 1 are arranged opposite each other, and the two second lightweight guide rails 2 are also arranged opposite each other. A guide rail connector 6 is located below the connection point of the first lightweight guide rail 1 and the second lightweight guide rail 2. The guide rail connector 6 is fixed to the first lightweight guide rail 1 and the second lightweight guide rail 2 by bolts. The height of the first lightweight guide rail 1 is lower than the height of the first and second lightweight guide rails 2. The two first lightweight guide rails 1 and the two second lightweight guide rails 2 are assembled into a frame structure.

[0016] Both the first lightweight guide rail 1 and the second lightweight guide rail 2 have I-beam cross-sections. Multiple steel bar connecting clips 3 are slidably connected to one of the first lightweight guide rail 1 and one of the second lightweight guide rail 2, while multiple steel bar fixing clips 5 are slidably connected to the other first lightweight guide rail 1 and the other second lightweight guide rail 2. Fixing screws 7 are provided on the side walls of both the steel bar connecting clips 3 and the steel bar fixing clips 5. When moved to the desired position, the fixing screws 7 are tightened, pressing against the lightweight guide rail and thus fixing the positions of the steel bar connecting clips 3 and the steel bar fixing clips 5. To accommodate different foundation sizes, the lightweight guide rails are available in various lengths. One end of the positioning steel bar 4 has an external thread, and the other end has an internal threaded hole. Two positioning steel bars 4 can be connected to each other to accommodate different foundation sizes.

[0017] One positioning steel bar 4 corresponds to one steel bar connecting buckle 3 and one steel bar fixing slot 5. The end of the steel bar connecting buckle 3 near the steel bar fixing slot 5 has a threaded hole. The threaded end of the positioning steel bar 4 is inserted into the threaded hole, and the positioning steel bar 4 is threadedly connected to the steel bar connecting buckle 3. Two elastic clips are fixed above the steel bar fixing slot 5, and a locking groove 51 is formed between the two elastic clips. The end of the positioning steel bar 4 away from the steel bar connecting buckle 3 is engaged with the locking groove 51.

[0018] Two positioning steel bars 4 form a group. The positioning steel bar 4 installed on the first lightweight guide rail 1 is lower than the positioning steel bar 4 installed on the second lightweight guide rail 2. A positioning nut 9 is threaded onto the embedded screw 8. The positioning nut 9 is higher than the positioning steel bar 4 on the first lightweight guide rail 1, and the positioning nut 9 and the positioning steel bar 4 on the second lightweight guide rail 2 are at the same horizontal height. The two positioning steel bars 4 in the same group on the first lightweight guide rail 1 are spaced closer together to clamp the embedded screw 8 in the middle. The two positioning steel bars 4 in the same group on the second lightweight guide rail 2 are spaced further apart to hold the positioning nut 9 in place, thus preventing the embedded screw 8 from shaking. The height of the embedded screw 8 can be adjusted by rotating it. The bottom of the positioning steel bar 4 installed on the first lightweight guide rail 1 rests on the top of the foundation template 10. The positioning steel bar 4 installed on the first lightweight guide rail 1 is a horizontal positioning steel bar 4, and the positioning steel bar 4 installed on the second lightweight guide rail 2 is a vertical positioning steel bar 4. The positioning steel bars 4 fix the embedded screw 8 both horizontally and vertically.

[0019] The working principle of the steel structure column base bolt pre-embedding auxiliary device of the present invention is as follows: Based on the dimensions of the concrete foundation, select appropriate first lightweight guide rail 1, second lightweight guide rail 2, and guide rail connector 6 to form a frame. Then, according to the positioning dimensions of the pre-embedded screw 8 required by the drawings, slide the steel strip connecting buckle 3 and steel strip fixing buckle 5 from the side of the guide rail to the required position and tighten the fixing screw 7 for fixation. Connect the positioning steel strip 4 to the steel strip connecting buckle 3 and insert the positioning steel strip 4 into the snap-fit ​​groove 51. The pre-embedded screw 8 is clamped by the same set of positioning steel strips 4 on the first lightweight guide rail 1, and the positioning nut 9 is clamped by the same set of positioning steel strips 4 on the second lightweight guide rail 2, thereby preventing the pre-embedded screw 8 from shaking.

[0020] This device can reduce dimensional deviations and temporary fixation during anchor bolt pre-embedding, avoiding subsequent construction difficulties and structural safety hazards caused by excessive dimensional deviations. At the same time, the device is easy to operate, which can significantly improve construction efficiency and reduce the time and cost of manual adjustment. In addition, its reusable nature also reduces material waste and conforms to the concept of green construction.

[0021] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
