[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0027] like Figure 1 - Figure 4As shown, a light steel factory roof tie rod tensioning device is mainly composed of several core components such as a first steel structure 1, a second steel structure 2, a tensioning tie rod 3 and a waist hole 4. The waist hole 4 is cleverly designed at both ends of the inner side of the first steel structure 1 and the second steel structure 2, which plays a role of connection and fixing.

[0028] U-shaped frames 5 are installed at the waist holes 4 of the first steel structure 1 and the second steel structure 2. There is a notch 8 at the front end of the U-shaped frame 5, which makes installation and adjustment more convenient. In addition, multiple equidistantly distributed installation holes 6 are opened on both sides of the end surface of the U-shaped frame 5, and these holes enable the U-shaped frame 5 to be firmly fixed on the steel structure. The upper and lower ends of the U-shaped frame 5 are also provided with slide grooves 7, and the fastening rods 9 can be inserted into the slide grooves 7. The rod body of the fastening rod 9 is provided with a roller 10, which plays a key role in the adjustment of the tensioning tie rod 3.

[0029] A connecting frame 11 is also installed on the fastening rod 9. This is an ingenious structure. Its inner and outer ends are respectively connected to a connecting ring 12 and a limiting ring 13. An adjusting screw 14 is connected to the limiting ring 13. This adjusting screw 14 extends from the U-shaped frame 5 for easy operation. The two oblique connecting rings 12 are connected to the tensioning brace 3. The tensioning brace 3 passes through the roller 10. When the adjusting screw 14 is rotated, the connecting frame 11, the roller 10 and the fastening rod 9 can be driven to move along the slide groove 7, thereby adjusting the tension of the tensioning brace 3.

[0030] In addition to the above adjustment methods, the tension of the tensioning brace 3 can also be adjusted by adjusting the relative position of the U-shaped frame 5 and the waist hole 4. This dual adjustment mechanism enables the device to adapt to various complex installation environments and usage requirements.

[0031] It is worth mentioning that the first steel structure 1 and the second steel structure 2 are designed in parallel, while the two tensioning braces 3 are designed in a staggered manner, which is not only beautiful but also enhances the stability of the overall structure. The tensioning braces 3 are tied to the connecting ring 12 and are sleeved at the tensioning braces 3 bundling position through a sleeve, which is both firm and beautiful.

[0032] The cross section of the U-shaped frame 5 is designed in a "U" shape, with protruding strips on both sides. This design is not only convenient for installation, but also can withstand greater tension. Multiple mounting holes 6 are evenly distributed on the protruding strips, making the installation more flexible. Bolts are inserted into the mounting holes 6 to fix the U-shaped frame 5 on the first steel structure 1 or the second steel structure 2, and a non-slip rubber gasket is also provided at the connection between the U-shaped frame 5 and the first steel structure 1 or the second steel structure 2, which further enhances the stability and sealing of the connection.

[0033] Both ends of the fastening rod 9 are threaded parts, and the threaded parts are sleeved with nuts and washers to fix the fastening rod 9 on the U-shaped frame 5. The roller 10 is also restricted on the fastening rod 9 by nuts. This design makes the connection between the various components tighter and more stable.

[0034] The cross section of the connecting frame 11 is also U-shaped, and the fastening rod 9 passes through the opening of the connecting frame 11. The connecting frame 11, the connecting ring 12 and the limiting ring 13 are designed as an integrated whole. Such a design not only improves the strength of the overall structure, but also makes the operation more convenient.

[0035] The connection between the limit ring 13 and the adjusting screw 14 adopts a T-key and T-slot connection structure, which is widely used on key chains. When the adjusting screw 14 is rotated, the adjusting screw 14 pushes the connecting frame 11, thereby adjusting the position of the roller 10 at the waist hole 4. When adjusting, the nuts at both ends of the fastening rod 9 need to be rotated so that it can slide on the slide groove 7. This structure makes the rotation of the adjusting screw 14 more stable and reliable. The adjusting screw 14 is connected to the U-shaped frame 5 by threads, which is simple and firm; it ensures the stability and safety of the steel structure workshop through multiple adjustment mechanisms and a firm connection method.

[0036] Working process: First, confirm that all parts of the tensioning device for the roof of the light steel factory have been correctly installed and the connection between each part is firm and reliable. This includes the first steel structure 1, the second steel structure 2, the tensioning rod 3, the waist hole 4, the U-shaped frame 5, the slide 7, the fastening rod 9, the roller 10, the connecting frame 11, the connecting ring 12, the limit ring 13 and the adjusting screw 14; before adjusting the tension, check the initial tension of the tensioning rod 3. This can be done by observing the tightness of the rod and measuring its tension. If the initial tension is found to be inappropriate, it needs to be adjusted; the initial tension of the tensioning rod 3 can be changed by adjusting the position of the U-shaped frame 5 in the waist hole 4. This can be done by loosening the fixing bolts of the U-shaped frame 5, moving the U-shaped frame 5 to a suitable position, and then re-fixing the bolts; if the tension requirement cannot be met by adjusting the position of the U-shaped frame 5, the position of the fastening rod 9 needs to be further adjusted. First, loosen the nuts at both ends of the fastening rod 9 so that the fastening rod 9 can slide on the slide 7. Then, turn the adjusting screw 14 to push the connecting frame 11 and the roller 10 to move along the slide 7, thereby changing the tension of the tensioning rod 3. During the adjustment process, it is necessary to constantly observe and measure the tension of the tensioning rod 3 to ensure that it reaches the appropriate tension; when the tension of the tensioning rod 3 is adjusted to the appropriate position, the position of the fastening rod 9 needs to be fixed. This can be done by tightening the nuts at both ends of the fastening rod 9. At the same time, it is also necessary to check whether the positions of the connecting frame 11, the roller 10 and the limit ring 13 are correct to ensure the stability and reliability of the entire device; if there are multiple tensioning rods 3 in the device, it is necessary to check and adjust their tension one by one according to the above steps to ensure that each rod reaches the appropriate tension; when the tension of all tensioning rods 3 is adjusted, it is necessary to check the stability and reliability of the entire device again. If any problems or abnormalities are found, they need to be handled and repaired in time. Finally, confirm that all parts are properly installed and secured and the entire unit is in good working condition.
