[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. Prefabricated steel structures can significantly improve the construction efficiency of building projects. To facilitate the transportation of prefabricated steel structures, they are often transported separately and welded on-site. During on-site welding of steel structures, connecting devices are often used for support and restraint to ensure the precision of the welding.

[0018] This utility model embodiment provides a tensionable steel structure connection device for houses.

[0019] Example 1; Please see Figure 1 , Figure 2 and Figure 3 The device includes a connecting platform 1, which provides space and support for the installation of other structures. During the construction of the house, the connecting platform 1 can use existing technologies such as lifting devices or cranes to lift the connected steel structural components to a suitable position for house construction, facilitating the welding of the steel structural components. The structural components shown in the attached drawings of this application are all illustrative examples. The specific real-time method should be combined with the functional requirements, assembly conditions and process limitations in the actual application scenario, and the structural parameters, size specifications and connection methods should be adaptively adjusted and optimized.

[0020] Please see Figure 1 and Figure 4 A set of fixed seats 2 are fixedly connected to the bottom surface of the connecting platform 1. Each fixed seat 2 has a sliding seat 3 slidably connected inside. The sliding seat 3 can adjust the clamping range of the device on the steel structure according to the size of the steel structure, so that the device can fix and clamp steel structure with different diameters, improving the applicability of the device. The bottom surface of the sliding seat 3 has a steel plate, which can achieve a clamping effect on the steel structure. Through the arrangement of a set of fixed seats 2, sliding seats 3 and tensioning mechanism 4, the device can clamp and fix steel structures at different angles, making it convenient for workers to weld steel structures at right angles. Compared with parallel butt joint connection devices, this application has a wider range of applicability.

[0021] The fixed seat 2 is provided with a U-shaped insert rod 12 on the outside. The end of the U-shaped insert rod 12 is threaded with a fixing nut 13. Both the fixed seat 2 and the sliding seat 3 have insertion holes of the same diameter inside. When the worker inserts the steel structure to be welded into the adjacent fixed seat 2, he first adjusts the length of the sliding seat 3 according to the size of the steel structure, then inserts both ends of the U-shaped insert rod 12 into the corresponding insertion holes, and uses the fixing nut 13 to fix the U-shaped insert rod 12, thus completing the clamping operation of the steel structure.

[0022] Example 2; Please see Figure 1 and Figure 2 A protective box 5 is fixedly connected to the top surface of the connecting platform 1. A set of transmission boxes 6 is fixedly connected to the outer surface of the protective box 5. A servo motor 7 is fixedly installed on the top surface of the protective box 5. The belt passes through the transmission box 6 and is slidably connected to the transmission box 6. When the servo motor 7 starts, it can drive the transmission bevel gear 8 inside the protective box 5 to rotate, thereby providing power for the tensioning operation of the tensioning mechanism 4. The protective box 5 and the transmission box 6 play a role in protecting the transmission structure of the device and can reduce the impact of external materials such as stones on the transmission state of the device. The top surface of the protective box 5 has a support plate for fixing the servo motor 7, which can provide stable support for the operation of the servo motor 7 and prevent the servo motor 7 from rotating during operation, thus affecting the use of the device.

[0023] Please see Figure 1 , Figure 2 and Figure 3 The protective box 5 is rotatably connected to a transmission bevel gear 8, which is fixedly connected to the output shaft of the servo motor 7. The transmission bevel gear 8 is rotatably connected to the connecting platform 1. The servo motor 7 is existing technology and will not be described in detail in this application. When the servo motor 7 is started, it can drive the transmission bevel gear 8 to rotate inside the protective box 5. The rotation of the transmission bevel gear 8 can drive the four driven bevel gears 9 outside to rotate through meshing, thereby providing power for the tensioning operation of the four tensioning mechanisms 4.

[0024] A set of driven bevel gears 9 meshes with the external of the transmission bevel gear 8. Each driven bevel gear 9 rotates inside the protective box 5. A driven rotating rod 10 is fixedly connected to the outer surface of each driven bevel gear 9. Each driven rotating rod 10 is rotatably connected to the transmission box 6. The protective box 5 and the transmission box 6 provide stable support and limit effect for the rotation of the driven bevel gear 9 and the driven rotating rod 10, ensuring the transmission stability of the driven rotating rod 10.

[0025] Both the take-up roller 401 and the driven rotating rod 10 are fixedly mounted with pulleys 11. The two pulleys 11 are connected by a belt drive. The rotation of the driven rotating rod 10 can drive the take-up roller 401 to rotate in the support frame 405 through the pulleys 11, so that the take-up roller 401 can wind up or release the tensioned steel cable 404, providing power for the tensioning operation of the tensioning mechanism 4. The two pulleys 11 have a certain diameter ratio to increase the transmission wrap angle between them. The belt needs to be maintained and replaced regularly to prevent the belt from slipping after long-term use.

[0026] Example 3; Please refer to it again. Figure 1 , Figure 2 and Figure 3 A tensioning mechanism 4 is set above the connecting platform 1. The tensioning mechanism 4 includes a take-up roller 401 and a tensioning table 402. Both ends of the tensioning table 402 are threaded with clamping bolts 403. By setting the tensioning mechanism 4, the device can apply a certain prestress to the steel structure through the tensioning cable 404 when clamping and fixing the steel structure, so that the steel structure can maintain a certain tension state, reduce the influence of vibration or external load on the steel structure, ensure the connection stability between the steel structure components to be welded, and improve the accuracy of the welding operation.

[0027] The tensioning mechanism 4 also includes a tensioning steel cable 404. The two ends of the tensioning steel cable 404 are fixedly connected to the take-up roller 401 and the tensioning table 402, respectively. The tensioning table 402 is used to fix the top surface of the steel structure. When the workers want to use this device to clamp the steel structure, they first push the steel structure around the device, then put the tensioning table 402 on the surface of the steel structure, and then push the steel structure into the fixed seat 2 and the sliding seat 3 for fixation. Finally, the servo motor 7 is started so that the take-up roller 401 can take up the tensioning steel cable 404, so that the tensioning steel cable 404 can tension the tensioning table 402, thereby performing tensioning operations on the steel structure. This effectively improves the fixing effect of the connection device and improves the convenience of subsequent installation and welding.

[0028] Two support frames 405 are fixedly connected to the top surface of the connecting platform 1. The two ends of the take-up roller 401 are rotatably connected to the two support frames 405 respectively. The support frames 405 provide stable support for the rotation of the take-up roller 401, so that the take-up roller 401 can stably wind up or release the tensioned steel cable 404, thereby improving the tensioning stability of the tensioning mechanism 4.

[0029] Working principle: When in use, the operator first moves the steel structure to be welded to the vicinity of the device, puts the tensioning table 402 on the top surface of the steel structure, then pushes the steel structure between the fixed seat 2 and the sliding seat 3, adjusts the position of the sliding seat 3 in the fixed seat 2 according to the size of the steel structure, then inserts both ends of the U-shaped plug rod 12 into the corresponding plug holes on the fixed seat 2 and the sliding seat 3, and tightens the fixing nut 13 to make the connecting platform 1 and the sliding seat 3 fit tightly with the steel structure. Then, the servo motor 7 is started. The start of the servo motor 7 can drive the transmission bevel gear 8 to rotate in the protective box 5. The transmission bevel gear 8 drives the driven bevel gear 9 to rotate through meshing, and then drives the winding roller 401 to rotate in the support frame 405 through the driven rotating rod 10 and the pulley 11. When the winding roller 401 rotates, it will wind up the tensioning steel cable 404. During the winding process, the tensioning steel cable 404 will tension the tensioning table 402, thereby keeping the steel structure in a taut state, reducing the impact of external vibration or external load, and ensuring the stability of the connection of the steel structure during welding operations.
