[0034] The water-shaped integrated support member 4 is formed by connecting multiple water-shaped components end to end; the upper and lower ends of the vertical rod of each water-shaped component are welded with a rectangular block 4.1; the upper chord groove rod 1 and the lower chord groove rod 2 have the same structure, both of which are long rods with a C-shaped cross-section; the rectangular block 4.1 fits into the grooves of the upper chord groove rod 1 and the lower chord groove rod 2.

[0035] U-shaped blocks 4.2 are welded to the upper and lower ends of both sides of the water-shaped integrated support member 4 and the upper and lower ends of the connection between the water-shaped components; U-shaped bayonet holes 2.1 are spaced apart along the length direction of the two flange plates of the upper chord groove rod 1 and the lower chord groove rod 2; the U-shaped blocks 4.2 fit into the U-shaped bayonet holes 2.1.

[0036] A mounting plate 5 is provided in the upper chord slot rod 1 and the lower chord slot rod 2 and at the U-shaped bayonet 2.1, and is fixed in the upper chord slot rod 1 and the lower chord slot rod 2 by mounting bolts 5.2. A U-shaped pad 5.1 is provided on the mounting plate 5; the U-shaped block 4.2 is engaged in the U-shaped pad 5.1.

[0037] The working process of the truss assembly structure of the utility model is as follows: during assembly, the lower part of the water-shaped row-in-one support piece 4 is clamped in the lower chord groove rod 2, and then the strip three-hole connecting block 3.5 is sleeved on the corresponding two lower support rods 3.3. At this time, the upper chord groove rod 1 is clamped on the upper part of the water-shaped row-in-one support piece 4, and the strip three-hole connecting block 3.5 is slid upward so that the middle part of it is sleeved on the upper support rod 3.1, and then the nut 3.6 is screwed on from the lower end of the upper support rod 3.1 to support the strip three-hole connecting block 3.5 and limit its falling, and make the strip three-hole connecting block 3.5 approximately in the middle of the height of the water-shaped row-in-one support piece 4, and then the nut 3.6 is screwed on from the upper end of the lower support rod 3.3, and the nut 3.6 is adjusted and tightened to complete the assembly. Similarly, it can be quickly disassembled by referring to the above operation.

[0038] The upper support rod 3.1 of the present embodiment is sleeved with an upper supporting spring 3.2, which is located between the strip three-hole connecting block 3.5 and the upper chord groove rod 1; the lower support rod 3.3 is sleeved with a lower supporting spring 3.4, which is located between the strip three-hole connecting block 3.5 and the lower chord groove rod 2. The upper supporting spring 3.2 abuts against the strip three-hole connecting block 3.5 and the upper chord groove rod 1, and the lower supporting spring 3.4 abuts against the strip three-hole connecting block 3.5 and the lower chord groove rod 2, thereby improving the fixing tightness between the upper chord groove rod 1, the water-shaped row of integrated support members 4 and the lower chord groove rod 2, thereby ensuring the overall stability of the truss.

[0039] In this embodiment, the upper chord groove rod 1 and the lower chord groove rod 2 are provided with a plurality of U-shaped bayonet holes 2.1 on the relatively inner sides. The U-shaped bayonet holes 2.1 penetrate the corresponding upper chord groove rod 1 and the lower chord groove rod 2 in the horizontal direction. The upper and lower parts of the water-shaped integrated support member 4 are welded with a plurality of U-shaped blocks 4.2 for clamping in the U-shaped bayonet holes 2.1. The water-shaped integrated support member 4 is first welded into a water-shaped component by welding galvanized cold steel sections, and then welded to form a plurality of water-shaped components. The U-shaped block 4.2 is welded at the connection between two adjacent water-shaped components and at the outer end of the outermost water-shaped component. The U-shaped bayonet holes 2.1 cooperate with the U-shaped block 4.2 to facilitate the positioning and installation between the water-shaped integrated support member 4 and the upper chord groove rod 1 and the lower chord groove rod 2.

[0040] A plurality of rectangular blocks 4.1 are welded to the upper and lower parts of the water-shaped integrated support member 4 of the present embodiment. The rectangular block 4.1 is located between two adjacent U-shaped blocks 4.2. The rectangular block 4.1 located at the upper part of the water-shaped integrated support member 4 is clamped in the upper chord groove rod 1, and the rectangular block 4.1 located at the lower part of the water-shaped integrated support member 4 is clamped in the lower chord groove rod 2. The rectangular block 4.1 is welded to the end of the vertical galvanized cold steel section in the middle of the water-shaped component. The upper and lower parts of the water-shaped integrated support member 4 are respectively restricted in the corresponding upper chord groove rod 1 and lower chord groove rod 2 through the rectangular block 4.1.

[0041] In the present embodiment, the upper chord groove rod 1 and the lower chord groove rod 2 are both provided with mounting plates 5 corresponding to the U-shaped bayonet 2.1. A U-shaped pad 5.1 is provided on one side of the mounting plate 5 adjacent to the water-shaped row-integrated support member 4. The middle part of the U-shaped block 4.2 is clamped in the U-shaped pad 5.1. Two mounting bolts 5.2 are provided on the mounting plate 5. The U-shaped pad 4.1 is located between the two mounting bolts 5.2. One end of the mounting bolt 5.2 passes through the mounting plate 5 and is threadedly engaged with the upper chord groove rod 1 and the lower chord groove rod 2 corresponding thereto. The mounting plate 5 is vertically provided with a U-shaped pad 5.1 corresponding to the mounting bolt 5.2. The upper and lower inner walls of the upper and lower chord slot rods 1 and 2 are provided with screw holes corresponding to the sockets. One end of the mounting bolt 5.2 passes through the socket and is threadedly engaged in the screw hole. The mounting bolt 5.2 cooperates with the mounting plate 4 to facilitate replacement of the aged and damaged U-shaped pad 5.1. The width of the U-shaped pad 5.1 is slightly smaller than the width of the U-shaped block 4.2. When the U-shaped block 4.2 is inserted into the U-shaped bayonet 2.1, the U-shaped block 4.2 will cause a certain amount of extrusion on the U-shaped pad 5.1 to deform it, thereby making the overall truss assembly tight and firm.
