Description

Technical Field

[0001] This utility model relates to the technical field of square tube frame connection structure, specifically a connection structure for an assembled square tube frame. Background Technology

[0002] In the field of building curtain wall or steel structure technology, the connection design of square tube frames is crucial to ensuring structural stability and installation efficiency. Traditional connection methods often suffer from problems such as exposed hardware on visible surfaces, a large amount of on-site welding work, and difficulty in guaranteeing installation quality. Utility Model Content

[0003] The present invention aims to provide a connection structure for a prefabricated square tube frame to solve the problems of exposed hardware and large on-site welding workload in traditional connection methods.

[0004] To achieve the above objectives, the basic solution of this utility model is as follows: A connection structure for an assembled square tube frame, the square tube frame including square tube columns and square tube beams, including two semi-circular head square neck bolts, positioning shims, adjusting shims, connecting plates, and fastening nuts. The square tube columns have double-headed gourd holes. The two semi-circular head square neck bolts are inserted through the middle of the double-headed gourd holes and then slide to both ends of the holes. The positioning shims are placed between the two semi-circular head square neck bolts, and the shape of the positioning shims corresponds to the double-headed gourd holes. The adjusting shim has two slots corresponding to the positions of the semi-circular head square neck bolts. The adjusting shim cooperates with the two semi-circular head square neck bolts and is fixed to the side of the square tube column. The connecting plate has two L-shaped connecting slots corresponding to the positions of the semi-circular head square neck bolts. The connecting plate is welded to the end of the square tube beam. The connecting plate locks the two semi-circular head square neck bolts along the L-shaped connecting slots and slides to the root of the L-shaped connecting slots before tightening the fastening nuts. The end of the square tube beam has a process hole for tightening the fastening nuts.

[0005] Furthermore, the connecting plate is also provided with several safety holes, and safety screws are provided at the safety holes.

[0006] Furthermore, the adjusting shim has an adhesive layer on one side, and the adjusting shim is attached to the side of the square tube column through the adhesive layer.

[0007] The beneficial effects of this scheme are: (1) By using the double-headed gourd holes and semi-circular head square neck bolts on the square tube column, a reliable connection between the square tube column and the square tube beam is achieved. This connection method is not only simple in structure, but also has high connection strength and can meet the requirements of structural stability.

[0008] (2) This solution hides the connecting hardware inside the structure, and the visible surface does not expose the connecting hardware, so that the visible surface remains clean and beautiful, and improves the overall appearance of the building.

[0009] (3) This solution uses bolts for assembly and connection, which avoids a lot of welding, rust removal and painting work on the installation site. This not only simplifies the installation process, but also ensures the installation quality and improves the installation efficiency. Attached Figure Description

Fastening nut; 7. Strip groove; 8. L-shaped connecting groove; 9. Process hole; 10. Safety hole; 11. Double-headed hoist hole; 12. Positioning shim. Example

[0017] Basic as Figures 1-5The diagram illustrates a connection structure for an assembled square tube frame. The square tube frame includes square tube columns 1 and square tube beams 2. It comprises two semi-circular head square neck bolts 3, adjusting shims 4, positioning shims 12, connecting plates 5, and fastening nuts 6. The square tube columns 1 have double-ended loop holes 11. The two semi-circular head square neck bolts 3 are inserted through the middle of the double-ended loop holes 11 and slide to both ends of the holes. The positioning shims 12 are placed between the two semi-circular head square neck bolts 3, and their shape matches the double-ended loop holes 11. The adjusting shims 4 have two shims that correspond to the positions of the semi-circular head square neck bolts 3. A corresponding strip groove 7 is provided. Adjusting shims 4 mate with two semi-circular head square neck bolts 3 and are fixed to the side of the square tube column 1. One side of the adjusting shim 4 has an adhesive layer, allowing it to be adhered to the side of the square tube column 1. The connecting plate 5 has two L-shaped connecting grooves 8 corresponding to the positions of the semi-circular head square neck bolts 3. The connecting plate 5 is welded to the end of the square tube beam 2. The connecting plate 5 engages with the two semi-circular head square neck bolts 3 along the L-shaped connecting grooves 8 and slides to the root of the L-shaped connecting groove 8 before tightening the fastening nut 6. The end of the square tube beam 2 has a process hole 9 for tightening the fastening nut 6. The connecting plate 5 also has several safety holes 10, where safety screws can be installed as needed.
