Description

Technical Field

[0001] This utility model relates to the field of steel structure column technology, specifically to a fixing structure for steel structure columns. Background Technology

[0002] With the development of steel technology, modern steel structures have been widely used in the construction industry. During construction, steel frame structures are frequently erected. These structures offer advantages such as structural stability, ease of construction, and overall protection for the building. The most common fixing method for steel column installation is foundation anchor bolt connection. Anchor bolts pre-embedded in the concrete foundation securely fix the steel column to the foundation. This method is suitable for most types of steel column installations, especially those requiring direct placement on the ground.

[0003] While anchor bolts effectively enhance the connection strength of steel structure columns, their strength is affected by the tightening force of the nuts during installation. Furthermore, over time, the nuts may gradually loosen from the bolts, causing the steel column to become unstable, potentially leading to swaying or even collapse, posing a safety hazard. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a fixing structure for steel columns in steel structures, thereby improving the stability of steel column installation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fixing structure for steel columns of steel structures, including a fixing component installed at the bottom of the column. The fixing component is installed on a poured concrete foundation. The fixing component includes a mounting plate and several threaded rods. The threaded rods are all pre-embedded in the concrete foundation. The mounting plate is fixedly connected to the bottom of the column. The ends of the threaded rods away from the concrete foundation all pass through the mounting plate and are connected to nuts. An anti-detachment component is connected between two adjacent nuts.

[0006] Furthermore, the number of threaded rods is even.

[0007] Furthermore, the anti-detachment component includes a connecting rod and two positioning rings, with two adjacent nuts fitted onto the two positioning rings respectively, and both ends of the connecting rod connected to the two positioning rings respectively.

[0008] Furthermore, the connecting rod includes a telescopic rod and a fixed rod. One end of the fixed rod has a telescopic hole, and the telescopic rod is slidably connected to the telescopic hole. The ends of the telescopic rod and the fixed rod that are far apart from each other are respectively connected to two positioning rings.

[0009] Furthermore, limit grooves are provided on the inner walls of both sides of the telescopic hole, and limit blocks are fixedly connected to both sides of the telescopic rod located at one end inside the telescopic hole. The two limit blocks are slidably connected to the two limit grooves respectively.

[0010] Furthermore, a retraction spring is fixedly connected to one end of the telescopic rod located inside the telescopic hole, and the other end of the retraction spring is fixedly connected to the telescopic hole.

[0011] Furthermore, both the telescopic rod and the fixed rod are fixedly connected to a fixed ring at their ends that are far apart from each other. Two positioning rings are located inside the two fixed rings respectively, and a ratchet structure connects the positioning rings and the fixed rings. The height of the nut is greater than the height of the fixed rings and the positioning rings.

[0012] Furthermore, the ratchet structure includes a limiting ring and several inclined springs. The inner wall of the limiting ring is fixedly connected to the middle position of the outer wall of the positioning ring. A rotating groove is opened at the middle position of the inner wall of the fixed ring. The positioning ring is rotatably connected to the rotating groove. Several inclined grooves are opened on both the upper and lower sides of the rotating groove. The inclined grooves are triangular. Several inclined springs are fixedly connected to the outer walls of the positioning ring located at the upper and lower ends of the limiting ring, respectively. Several inclined springs are matched with several inclined grooves.

[0013] Furthermore, an anti-disengagement cap is fitted onto the top of the nut and the threaded rod, and a groove matching the nut is provided at the bottom of the anti-disengagement cap.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This type of steel column fixing structure uses an anti-loosening component to fix two adjacent nuts, thereby preventing the nuts from rotating and loosening on the threaded rod during subsequent use. This ensures a firm connection between the nut and the threaded rod, improves the stability of the steel column's fixed installation on the concrete foundation, and makes the installation of the steel column safer and more stable.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Please see Figures 1 to 7 A fixing structure for steel columns of a steel structure includes a fixing component installed at the bottom of the column 1. The fixing component is installed on a poured concrete foundation 2. The fixing component includes a mounting plate 3 and several threaded rods 4. The several threaded rods 4 are all pre-embedded in the concrete foundation 2. The mounting plate 3 is fixedly connected to the bottom of the column 1. The ends of the several threaded rods 4 away from the concrete foundation 2 all pass through the mounting plate 3 upward and are connected to nuts 5. An anti-detachment component is connected between two adjacent nuts 5.

[0026] like Figures 1 to 7 As shown, the main improvement of this utility model lies in enhancing the stability and safety of the steel column installed on the concrete foundation 2, such as... Figures 1 to 7 As shown, in the steel column fixing structure of this utility model, multiple threaded rods 4 are pre-embedded in the poured concrete foundation 2. When installing the steel column 1, multiple pre-set mounting holes on the mounting plate 3 at the bottom of the column 1 are fitted onto the threaded rods 4. Then, nuts 5 are gradually screwed down from the top of the threaded rods 4 until the nuts 5 are against the top of the mounting plate 3. After all the nuts 5 are tightened and fixed, an anti-loosening component is used to connect two adjacent nuts 5 to each other, so that the nuts 5 on the two adjacent threaded rods 4 cannot rotate. During the subsequent use of the column 1, the mounting plate 3 can exert an upward squeezing force on the nuts 5. Since the nuts 5 cannot rotate, it can ensure that the mounting plate 3 will not loosen on the concrete foundation 2, thereby improving the installation stability of the column 1 on the concrete foundation 2 and the safety of subsequent use.

[0027] like Figures 1 to 4As shown, the number of threaded rods 4 is even. An even number of threaded rods 4 ensures that when nuts 5 on adjacent threaded rods 4 are connected using an anti-loosening assembly, there will be no problem of a nut 5 on a single threaded rod 4 failing to match another nut 5. This ensures that multiple nuts 5 can be paired and connected using the anti-loosening assembly.

[0028] like Figures 1 to 7 As shown, the anti-loosening assembly includes a connecting rod 6 and two positioning rings 7. The two positioning rings 7 are respectively fitted onto two adjacent nuts 5. Both ends of the connecting rod 6 are connected to the two positioning rings 7. During installation, the two positioning rings 7 at both ends of the connecting rod 6 are moved downwards from the top of the two adjacent threaded rods 4 and fitted onto the outside of the nuts 5 under the threaded rods 4. The non-circular grooves on the inner side of the positioning rings 7 that match the nuts 5 prevent the nuts 5 tightened on the threaded rods 4 from rotating, thus avoiding the loosening problem caused by the nuts 5 rotating back.

[0029] like Figure 4 and Figure 5 As shown, the connecting rod 6 includes a telescopic rod 8 and a fixed rod 9. One end of the fixed rod 9 has a telescopic hole 901, and the telescopic rod 8 is slidably connected to the telescopic hole 901. The ends of the telescopic rod 8 and the fixed rod 9 that are far apart from each other are respectively connected to two positioning rings 7. By telescopically moving the telescopic rod 8 within the telescopic hole 901 of the fixed rod 9, the distance between the two positioning rings 7 can be adjusted, thereby adapting to the distance between the two nuts 5 that need to be fixed, improving the applicability of the anti-detachment component.

[0030] like Figures 4 to 6 As shown, limit grooves 902 are formed on both inner walls of the telescopic hole 901. Limit blocks 10 are fixedly connected to both sides of the telescopic rod 8 located inside the telescopic hole 901. The two limit blocks 10 are slidably connected to the two limit grooves 902 respectively. By moving the limit blocks 10 within the limit grooves 902, the connection between the telescopic rod 8 and the fixed rod 9 can be prevented from disengaging, ensuring that the telescopic rod 8 and the fixed rod 9 always remain connected.

[0031] like Figures 1 to 7 As shown, a retraction spring 11 is fixedly connected to one end of the telescopic rod 8 located inside the telescopic hole 901, and the other end of the retraction spring 11 is fixedly connected to the telescopic hole 901. The retraction spring 11 can always pull the telescopic rod 8 into the telescopic hole 901. When the anti-fall-off component is not in use, the telescopic rod 8, which is retracted in the telescopic hole 901, is subjected to the tension of the retraction spring 11, and the telescopic rod 8 will not move freely, thus improving the storage stability of the anti-fall-off component.

[0032] like Figures 1 to 7As shown, both the telescopic rod 8 and the fixed rod 9 have fixed rings 12 at their ends that are far apart from each other. Two positioning rings 7 are located inside the two fixed rings 12, and a ratchet structure connects the positioning rings 7 and the fixed rings 12. The height of the nut 5 is greater than the height of the fixed rings 12 and the positioning rings 7. Since the tightened nut 5 may not be able to align with the corners of the positioning rings 7, during installation, the positioning rings 7 can be placed on the nut 5 before it is fully tightened. Then, the nut 5 can be tightened by the part protruding above the positioning rings 7. This makes it more convenient to use. During this process, as the nut 5 is tightened, the positioning rings 7 can rotate inside the fixed rings 12 following the nut 5. After the nut 5 is finally tightened, the ratchet structure ensures that the positioning rings 7 can only rotate in one direction within the fixed rings 12, and cannot rotate in the opposite direction. This prevents the tightened nut 5 from turning back, thus avoiding loosening of the nut 5 tightened on the threaded rod 4.

[0033] like Figure 7 As shown, the ratchet structure includes a limiting ring 13 and several inclined spring pieces 14. The inner wall of the limiting ring 13 is fixedly connected to the middle position of the outer wall of the positioning ring 7. A rotating groove 101 is provided at the middle position of the inner wall of the fixing ring 12. The positioning ring 7 is rotatably connected to the rotating groove 101. Several inclined grooves 102 are provided on both the upper and lower sides of the rotating groove 101. The inclined grooves 102 are triangular. Several inclined spring pieces 14 are fixedly connected to the outer walls of the positioning ring 7 located at the upper and lower ends of the limiting ring 13, respectively. Several inclined spring pieces 14 are matched with several inclined grooves 102. When the nut 5 is turned, the positioning ring 7 rotates with the nut 5. At the same time, the connection between the limiting ring 13 and the rotating groove 101 in the fixed ring 12 ensures that the positioning ring 7 is always connected to the fixed ring 12. During the rotation, the inclined spring piece 14 is squeezed into the gap between the positioning ring 7 and the fixed ring 12 in the inclined groove 102 and enters the next inclined groove 102 with the rotation, repeating the cycle. When the nut 5 stops turning, the end of the inclined spring piece 14 abuts against the inner wall of the inclined groove 102, so that the positioning ring 7 cannot rotate in the opposite direction in the fixed ring 12, thus preventing the nut 5 from rotating loose on the threaded rod 4.

[0034] like Figures 1 to 7 As shown, an anti-detachment cap 15 is fitted onto the top of the nut 5 and the threaded rod 4. The bottom of the anti-detachment cap 15 has a groove 103 that matches the nut 5. After the installation and fixing between the column 1 and the concrete foundation 2 are completed, and the anti-detachment component is installed on the nut 5, the anti-detachment cap 15 can be installed on the top of each nut 5. The anti-detachment cap 15 is fitted onto the top of the threaded rod 4, and the groove 103 at the bottom fits onto the top of the nut 5, thereby pressing the anti-detachment component against the bottom of the nut 5 and preventing the anti-detachment component from moving up from the nut 5. The anti-detachment cap 15 can be made of silicone, which can be used to more stably fit onto the threaded rod 4 and the nut 5 by utilizing the elasticity of silicone.

[0035] 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.
