Description

A fixing device for I-beams Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a fixing device for I-beams. Background Technology

[0002] I-beams are long steel bars with an I-shaped cross-section, also known as steel beams. Their cross-section is regular and precise in size, and they have good bending resistance. They are easy to cut, fix, and connect. They have high strength and can withstand large loads. Due to their unique shape and excellent performance, I-beams are widely used in building structures, machinery manufacturing, bridge construction, and other fields.

[0003] There are various methods for fixing I-beams, mainly including fixed connections, bolt connections, and clamp fixation. Existing I-beam fixing clamps have the advantages of being quick and easy to use, but they also have drawbacks such as insufficient tightness and loosening after long-term use. Therefore, it is necessary to design a practical and reliable fixing device for I-beams. Summary of the Invention

[0004] The purpose of this utility model is to provide a fixing device for I-beams to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a fixing device for an I-beam, comprising an I-beam, the I-beam including upper and lower flanges, a middle web between the two flanges, a fixed component placed on one flange, and two U-shaped fixing shafts snapped onto each fixed component at the position to be fixed on the I-beam, the U-shaped fixing shafts being U-shaped, and the lower end of the U-shaped fixing shaft passing through the flange tightly attached to the fixed component and having a first thread, the lower end of the U-shaped fixing shaft being threaded with a first nut through the first thread.

[0006] According to the above technical solution, the two U-shaped fixed shafts in a fixed position are symmetrically installed with the intermediate web plate as the reference surface.

[0007] According to the above technical solution, friction blocks are provided on both sides of the fixed component. The friction blocks are made of a material with high friction with the I-beam. The lower surface of each friction block is in close contact with the flange. The friction blocks are located between the two U-shaped fixing shafts. A pair of springs are fixedly connected above each friction block. A fixing block is fixedly connected to the other end of each pair of springs. A U-shaped plate is fixedly connected above the two fixing blocks.

[0008] According to the above technical solution, each of the fixed blocks is also provided with a shaft, both ends of which pass through the U-shaped fixed shafts on both sides and are provided with a second thread. The two ends of the shaft are threadedly connected to a second nut through the second thread.

[0009] According to the above technical solution, the shape and structure design of the U-shaped fixing shaft is adapted to the fixed part, that is, when the U-shaped fixing shaft is installed on the fixed part, the inner side of the U-shaped fixing shaft can closely fit and wrap around the three outer surfaces of the fixed part.

[0010] According to the above technical solution, the U-shaped plate has a "U" shaped structure, and its shape and structure design are adapted to the fixed part. That is, when the U-shaped plate is installed on the fixed part, the inner side of the U-shaped plate can tightly fit and wrap around the three outer surfaces of the fixed part.

[0011] Compared with the prior art, the beneficial effects achieved by this utility model are: This utility model,

[0012] (1) A U-shaped fixing shaft is provided, which is U-shaped. The lower end of the U-shaped fixing shaft passes through the flange that is in close contact with the fixed part and is provided with a first thread. A through hole is provided at the corresponding position of the flange to ensure that the lower end of the U-shaped fixing shaft passes through the flange. The lower end of the U-shaped fixing shaft is connected to a first nut through the first thread. The U-shaped fixing shaft is firmly fixed to the flange through the threaded connection of the first nut, thereby achieving the fixing of the fixed part. The U-shaped design of the U-shaped fixing shaft not only provides sufficient wrapping force, but also enhances the stability of the fixing through the tightening effect of the first nut. This design makes it difficult for the fixed part to loosen or fall off when subjected to external force, ensuring the reliability and durability of the fixing.

[0013] (2) By setting a U-shaped fixing shaft symmetrically installed with the middle web as the reference plane, it can be ensured that the force on both sides of the fixed part can be evenly distributed when subjected to external force, thereby avoiding skewing or twisting. This symmetrical installation method greatly improves the stability and reliability of the fixation;

[0014] (3) The friction blocks are made of a material with high friction with the I-beam. The lower surface of each friction block is in close contact with the flange. A pair of springs are fixedly connected to the top of each friction block. A fixing block is fixedly connected to the other end of each pair of springs. A U-shaped plate is fixedly connected to the top of the two fixing blocks. The inner side of the U-shaped plate can be in close contact with and wrap around the three outer surfaces of the fixed part. Sufficient friction can be generated between the friction block and the flange. This not only provides additional fixing force, but also enhances the stability of the entire fixing device through its high friction characteristics, which is beneficial for the fixed part to be fixed on the I-beam.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4. This utility model provides a technical solution: a fixing device for an I-beam, comprising an I-beam 1, which includes upper and lower flanges 11, with a central web 12 between the two flanges 11. A fixed component 8 is placed on one flange 11, ensuring that the positions to be fixed are aligned. Two U-shaped fixing shafts 2 are engaged with each fixed component 8 at the position to be fixed on the I-beam 1. The U-shaped fixing shafts 2 are U-shaped, and their lower ends pass through the flange 11 that is in close contact with the fixed component 8 and have a first thread 21. A corresponding through hole is provided on the flange 11 to ensure that the lower end of the U-shaped fixing shaft 2 passes through the flange 11. A first nut 22 is threadedly connected to the lower end of the U-shaped fixing shaft 2 via the first thread 21. The U-shaped fixing shaft 2 is firmly fixed to the flange 11 through the threaded connection of the first nut 22, thereby achieving the fixing of the fixed part 8. The "U" shape design of the U-shaped fixing shaft 2 not only provides sufficient wrapping force, but also enhances the stability of the fixation through the tightening effect of the first nut 22. This design makes it difficult for the fixed part 8 to loosen or fall off when subjected to external force, ensuring the reliability and durability of the fixation.

[0023] As shown in Figure 1, the two U-shaped fixing shafts 2 in a fixed position are symmetrically installed with the intermediate web plate 12 as the reference plane. Symmetrical installation of the U-shaped fixing shafts 2 with the intermediate web plate 12 as the reference plane ensures that the force on both sides of the fixed component 8 is evenly distributed when subjected to external forces, thus avoiding skewing or twisting. This symmetrical installation method greatly improves the stability and reliability of the fixing.

[0024] As shown in Figure 1, friction blocks 3 are provided on both opposite sides of the fixed component 8. The friction blocks 3 are made of a material with high frictional force with the I-beam 1. The lower surface of each friction block 3 is tightly fitted with the flange 11, and the friction blocks 3 are located between two U-shaped fixing shafts 2. A pair of springs 4 are fixedly connected above each friction block 3, and a fixing block 5 is fixedly connected to the other end of each pair of springs 4. A U-shaped plate 7 is fixedly connected above the two fixing blocks 5. The U-shaped plate 7 can assist in bearing force, which helps to ensure that the fixed component 8 is not easily loosened or detached when subjected to external force. The choice of material for the friction blocks 3 ensures that sufficient frictional force can be generated between the friction blocks 3 and the flange 11. This not only provides additional fixing force, but also enhances the stability of the entire fixing device through its high frictional characteristics, which is beneficial for the fixed component 8 to be fixed on the I-beam 1. It is worth noting that when the fixed component 8 is installed and fixed on the I-beam 1 using this device, the springs 4 are in a slightly compressed state, which helps to press the friction blocks 3 downward, thereby enhancing the frictional effect between the friction blocks 3 and the I-beam 1.

[0025] As shown in Figure 1, each fixing block 5 is also fitted with a shaft 6. Both ends of the shaft 6 pass through the U-shaped fixing shafts 2 on both sides and are threaded with a second thread 61. The two ends of the shaft 6 are threadedly connected to a second nut 62 through the second thread 61. By passing the shaft 6 through the U-shaped fixing shafts 2 on both sides and fixing it through the threaded connection of the second nut 62, the fixing block 5 and its connected spring 4, friction block 3 and U-shaped plate 7 are fixedly connected to the U-shaped fixing shaft 2.

[0026] As shown in Figure 4, the shape and structure of the U-shaped fixing shaft 2 are adapted to the fixed part 8. That is, when the U-shaped fixing shaft 2 is installed on the fixed part 8, the inner side of the U-shaped fixing shaft 2 can tightly fit and wrap around the three outer surfaces of the fixed part 8. This design ensures that the contact area between the U-shaped fixing shaft 2 and the fixed part 8 is maximized, thereby improving the stability and reliability of the fixation.

[0027] As shown in Figure 4, the U-shaped plate 7 has a "U"-shaped structure, and its shape is designed to fit the fastened component 8. That is, when the U-shaped plate 7 is installed on the fastened component 8, the inner side of the U-shaped plate 7 can tightly fit and wrap around the three outer surfaces of the fastened component 8. This design ensures that the contact area between the U-shaped plate 7 and the fastened component 8 is maximized, thereby improving the stability and reliability of the fastening.

[0028] Working principle: First, place the fixed part 8 on the I-beam 1 at the position to be fixed, and ensure that the two positions are aligned. Then, snap a pair of U-shaped fixing shafts 2 onto the fixed part 8. Four through holes are opened at the corresponding positions on the flange 11 of the I-beam 1, so that the lower ends of the pair of U-shaped fixing shafts 2 pass through the through holes and are connected by the thread of the first nut 22, so that the U-shaped fixing shafts 2 are firmly fixed on the flange 11, thereby achieving the fixing of the fixed part 8. Next, the U-shaped plate 7 is clipped onto the fixed part 8 and pressed so that the inner surface of the U-shaped plate 7 is tightly attached to the upper surface of the fixed part 8. At this time, the spring 4 is compressed, and the lower surface of the friction block 3 is tightly attached to the flange 11. The hole on the fixing block 5 for the shaft 6 to pass through is aligned with the hole on the U-shaped fixing shaft 2 for the shaft 6 to pass through. The shaft 6 is passed through and fixed by the threaded connection of the second nut 62, so that the fixing block 5 and its connected spring 4, friction block 3 and U-shaped plate 7 are fixedly connected to the U-shaped fixing shaft 2. Friction can be generated between the friction block 3 and the flange 11, providing additional fixing force and enhancing the stability of the entire fixing device, which is used to assist in fixing the fixed part 8 on the I-beam 1.
