[0003] Traditional large-span, wide-bay connection structures are fixed with a large number of bolts. Bolt fixing is not only prone to loosening, but also cumbersome to install. In addition, stress concentration occurs around the bolt holes, which can easily lead to hole wall cracks and fatigue fractures under alternating loads (such as wind vibration and earthquakes).

[0004] Therefore, it is necessary to invent a large-span, large-opening connection structure to solve the above problems. Utility Model Content

By placing the connecting frame above the steel frame and support rod, the first insert block above the support rod and the second insert block above the steel frame are respectively inserted into the slots inside the connecting frame. When connecting the sub-truss assembly, the connecting block on the left side of the sub-truss assembly needs to be inserted into the rightmost slot of the connecting frame. The slot inside the second insert block has a connecting groove on the left side. Thus, the connecting block is not only inserted into the connecting frame and the steel frame, but also into the connecting groove inside the second insert block, thereby strengthening the connection between the steel frame, the connecting frame, and the sub-truss assembly. Then, it is welded together to solve the problem of the traditional large-span, wide-bay connection structure mentioned in the background art, which uses a large number of bolts for fixing. Bolt fixing is not only prone to loosening, but also cumbersome to connect. Moreover, stress concentration exists around the bolt holes, which can easily cause hole wall cracks and fatigue fractures under alternating loads.

Threaded grooves 6 are opened inside the connecting plate 5. Support component 7, located outside the sub-truss component 2 and the main truss component 1, is used for support. By placing the connecting frame 105 above the steel frame 101 and the support rod 102, the first insert 103 above the support rod 102 and the second insert 104 above the steel frame 101 are respectively inserted into the slots 106 inside the connecting frame 105. When connecting the sub-truss component 2, the mating block 3 on the left side of the sub-truss component 2 needs to be inserted into the rightmost slot 106 of the connecting frame 105. The slot 106 has a mating groove 107 on the left side where the second insert 104 is inserted. Thus, the mating block 3 is inserted not only into the connecting frame 105 and the steel frame 101, but also into the mating groove 107 inside the second insert 104, thereby strengthening the connection between the steel frame 101, the connecting frame 105, and the sub-truss component 2. Then, it is welded together.

[0020] like Figure 1 and Figure 2 As shown, the support rods 102 are arranged in a cross pattern, and the steel frame 101 is arranged in a U-shape. Multiple sets of support rods 102 are welded inside the steel frame 101 to enhance the overall support strength.

[0021] like Figure 2 and Figure 5 As shown, the first insert 103 above the steel frame 101 is movably engaged with the second insert 104 above the support rod 102 and the slot 106 below the connecting frame 105. The steel frame 101 and the internally welded support rod 102 are connected by inserting the first insert 103 and the second insert 104 into the slot 106 below the connecting frame 105, and then connected by welding, thereby strengthening the connection between them.

[0022] like Figure 2 and Figure 5As shown, multiple sets of slots 106 are provided. The outer side of the rightmost slot 106 has a groove. When connecting the sub-truss assembly 2, the docking block 3 on the left side of the sub-truss assembly 2 needs to be inserted into the rightmost slot 106 of the connecting frame 105. The left side of the second insert 104 inserted into the slot 106 has a docking groove 107. Thus, the docking block 3 is not only inserted into the connecting frame 105 and the steel frame 101, but also into the docking groove 107 inside the second insert 104, thereby strengthening the connection between the steel frame 101, the connecting frame 105 and the sub-truss assembly 2.

[0023] like Figure 2 and Figure 5 As shown, the right-side connecting block 3 of the sub-truss assembly 2 is movably engaged with the slots and connecting grooves 107 opened in the connecting frame 105 and the steel frame 101. The connecting block 3 on the left side of the sub-truss assembly 2 is inserted into the slots and connecting grooves 107 on the right side of the steel frame 101 and the connecting frame 105 to strengthen the connection between the connecting frame 105 and the steel frame 101, and also facilitates the extension of the connection.

A fixing bolt 9 passes through the external thread of the mounting frame 8. A reinforcing rib 10 is fixedly connected to the outside of the support component 7. A support seat 11 is fixedly connected above the reinforcing rib 10. A limiting block 12 is fixedly connected above the support seat 11. The connecting plate 5 on the outside of the main truss component 1 and the secondary truss component 2 is locked in the mounting frame 8 inside the support component 7. The limiting groove 4 below the secondary truss component 2 is locked onto the limiting block 12 above the outer support seat 11. Finally, the fixing bolt 9 passes through the mounting frame 8 and the connecting plate 5 to fix the main truss component 1 and the secondary truss component 2. The support seat 11 and the reinforcing rib 10 below the secondary truss component 2 are set to enhance the connection stability between the overall steel frame 101 and the secondary truss component 2.

[0025] like Figure 3 and Figure 4 As shown, the connecting plate 5 is movably sleeved with the mounting frame 8, and the fixing bolt 9 passes through the mounting frame 8 and the connecting plate 5. The limiting block 12 above the support base 11 is movably inserted into the limiting groove 4 below the sub-truss assembly 2. The connecting plate 5 on the outside of the sub-truss assembly 2 is placed in the mounting frame 8, and then the fixing bolt 9 passes through to strengthen the firmness between the sub-truss assembly 2 and the support assembly 7. The limiting groove 4 below the sub-truss assembly 2 is inserted into the limiting block 12 above the support base 11 to provide support.

The slot 106 contains a connecting groove 107 on the left side of the second insert 104. Thus, the connecting block 3 is inserted not only into the connecting frame 105 and the steel frame 101, but also into the connecting groove 107 inside the second insert 104, strengthening the connection between the steel frame 101, the connecting frame 105, and the sub-truss assembly 2. Next, the main truss assembly 1 and the welded secondary truss assembly 2 are welded together. Then, a crane is used to lift the entire main truss assembly 1 and the welded secondary truss assembly 2. The connecting plates 5 on the outside of the main truss assembly 1 and the secondary truss assembly 2 are respectively inserted into the mounting frame 8 inside the support assembly 7. The limiting groove 4 below the secondary truss assembly 2 is inserted into the limiting block 12 above the support seat 11 on the outside of the support assembly 7. Finally, the main truss assembly 1 and the secondary truss assembly 2 are fixedly connected by fixing bolts 9 through the mounting frame 8 and the connecting plate 5. The support seat 11 and the reinforcing rib 10 below the secondary truss assembly 2 are set to enhance the connection stability between the overall steel frame 101 and the secondary truss assembly 2. In this way, the use process of this large-span, large-bay connection structure is completed.
