Description

Technical Field

[0001] The invention discloses a steel tube truss structure based on a four-tube framework, belonging to the technical field of steel tube trusses. Background Art

[0002] There are many double-tube trusses on the market. The distance between the frames of this type of steel tube truss is relatively close, so a huge amount of steel is used, resulting in high costs. Summary of the invention

[0003] The present invention overcomes the shortcomings of the prior art and provides a steel tube truss structure based on a four-tube framework. By adjusting the spacing between the beams and reducing the use of web members, the amount of steel used is greatly reduced, effectively saving construction costs.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: a steel tube truss structure based on a four-tube structure, including multiple steel tube trusses, the multiple steel tube trusses are arranged longitudinally and equidistantly in sequence, and the adjacent steel tube trusses are connected by multiple longitudinally arranged web bars. The structure of the steel tube truss is: including a first upper chord tube, a second upper chord tube, a first lower chord tube and a second lower chord tube, the first upper chord tube, the second upper chord tube, the first lower chord tube and the second lower chord tube are all arranged in parallel, and the cross section forms a square frame structure, the first upper chord tube and the second upper chord tube are located above the first lower chord tube and the second lower chord tube, and connecting web bars are arranged between the first upper chord tube and the second upper chord tube, and the first lower chord tube and the second lower chord tube;

[0005] A plurality of cross-distributed diagonal web members are arranged between the first steel tube truss and the second steel tube truss, and between the penultimate steel tube truss and the penultimate steel tube truss. Only one row of cross-distributed diagonal steel wire ropes is longitudinally arranged on both sides near the top between the other adjacent steel tube trusses.

[0006] The cross section of the steel tube truss is a square.

[0007] The diagonal brace is arranged between the adjacent first upper chord tube and the second upper chord tube.

[0008] The oblique steel wire rope is arranged between the adjacent first upper chord tube and the second upper chord tube.

[0009] The longitudinal distance between the first upper chord tube and the second upper chord tube of each steel tube truss is smaller than the longitudinal distance between two adjacent steel tube trusses.

[0010] Compared with the prior art, the present invention has the following beneficial effects: the present invention utilizes the principle that a quadrilateral can stand in a U-shape, and each steel tube truss is arranged as a four-tube structure. The four-tube structures are connected in sequence by connecting webs, so that each steel tube truss 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 can be enlarged, so as to achieve the purpose of saving the number of steel tube trusses 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 located in the middle does not need to be tightened and fixed by an inclined web, and the purpose of connection can be achieved by only connecting the webs, and a small amount of inclined steel wire ropes are used to achieve the tightening and fixing of the entire truss structure.

[0014] In the figure: 1 is a steel tube truss, 11 is a first upper chord tube, 12 is a second upper chord tube, 13 is a first lower chord tube, 14 is a second lower chord tube, 15 is a connecting web member, 2 is a web member, 3 is a diagonal web member, and 4 is a diagonal steel wire rope. DETAILED DESCRIPTION

[0015] like Figure 1 , Figure 2 As shown, a steel tube truss structure based on a four-tube structure of the present invention includes multiple steel tube trusses 1, and 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 members 2. The structure of the steel tube truss 1 is as follows: 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 members 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;

[0016] 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 only one row of cross-distributed diagonal steel wire ropes 4 are longitudinally arranged on both sides near the top between the remaining adjacent steel tube trusses 1.

[0017] The cross section of the steel tube truss 1 is a square.

[0018] The diagonal web member 3 is arranged between the adjacent first upper chord tube 11 and the second upper chord tube 12 .

[0019] The inclined steel wire rope 4 is arranged between the adjacent first upper chord tube 11 and the second upper chord tube 12 .

[0020] 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 .

[0021] The present invention utilizes the principle that a quadrilateral can stand in a U-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 a small amount of inclined steel wire ropes 4 are used to achieve the tightening and fixing of the entire truss structure.

[0022] The present invention only needs to connect the upper sides of the first and second, and the penultimate and second to last steel tube trusses with inclined web members 3 to enhance stability to achieve the traditional structural strength, saving a large number of inclined web members 3, and using inclined steel wire ropes 4 for tightening and fixing, which greatly reduces the deadweight of the truss itself and makes the truss more stable.

[0023] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
