DETAILED DESCRIPTION

[0014] like Figure 1 , Figure 2 As shown, the utility model is a four-tube frame steel tube truss structure, including multiple steel tube trusses 1, the multiple steel tube trusses 1 are arranged longitudinally and equidistantly in sequence, and the adjacent steel tube trusses 1 are connected by multiple longitudinally arranged web bars 2, and the structure of the steel tube truss 1 is: including a first upper chord tube 11, a second upper chord tube 12, a first lower chord tube 13 and a second lower chord tube 14, the first upper chord tube 11, the second upper chord tube 12, the first lower chord tube 13 and the second lower chord tube 14 are all arranged in parallel, and the cross section forms a square frame structure, the first upper chord tube 11 and the second upper chord tube 12 are located above the first lower chord tube 13 and the second lower chord tube 14, and connecting web bars 15 are arranged between the first upper chord tube 11 and the second upper chord tube 12, the first lower chord tube 13 and the second lower chord tube 14;

[0015] A plurality of cross-distributed diagonal web members 3 are arranged between the first steel tube truss 1 and the second steel tube truss 1, and between the penultimate steel tube truss 1 and the penultimate steel tube truss 1, and cross-distributed diagonal steel wire ropes 4 are arranged between the remaining adjacent steel tube trusses 1, and the longitudinal distance between the first upper chord tube 11 and the second upper chord tube 12 of each steel tube truss 1 is smaller than the longitudinal distance between two adjacent steel tube trusses 1.

[0016] The cross section of the steel tube truss 1 is a square.

[0017] The diagonal web member 3 is arranged between the adjacent first upper chord tube 11 and the second upper chord tube 12 .

[0018] The inclined steel wire rope 4 is arranged between the adjacent first upper chord tube 11 and the second upper chord tube 12 .

[0019] The utility model utilizes the principle that a quadrilateral can stand in a U-shaped shape, and sets each steel tube truss 1 as a four-tube structure. The four-tube structures are connected in sequence by connecting webs 15, so that each steel tube truss 1 can achieve twice the bearing capacity and structural strength of a traditional steel tube truss. Therefore, the distance between two adjacent traditional steel tube trusses 1 can be enlarged, so as to achieve the purpose of saving the number of steel tube trusses 1 in a certain space, thereby greatly reducing the amount of steel used. Then, utilizing the principle that a four-tube structure can stand, each steel tube truss 1 in the middle does not need to be tightened and fixed by the inclined webs 3, and the purpose of connection can be achieved by only connecting the webs 15, and the upper sides of the adjacent steel tube trusses 1 are tightened and fixed with the inclined steel wire ropes 4, so as to achieve the tightening and fixation of the entire truss structure.

[0020] The utility model only needs to connect the upper sides of the first and second steel tube trusses and the penultimate and second to last steel tube trusses with inclined web members 3 to enhance stability and achieve the traditional structural strength, saving a large number of inclined web members 3, and using inclined steel wire ropes 4 to tighten and fix the upper sides of the remaining steel tube trusses, which greatly reduces the deadweight of the trusses themselves and makes the trusses more stable.
