[0002] Steel box girder is an important building structure. It is usually composed of chords, web members and node plates. Steel trusses are commonly used as the main load-bearing components and are used in large buildings such as high-speed railway stations, airports, stadiums and convention centers.
[0003] For example, Chinese utility model patent CN217949527U discloses a high-load-bearing box-type truss steel structure, including main beams, secondary beams, and diagonal web members. There are four main beams, each equipped with five sets of secondary beams and two rows of diagonal web members. The five sets of secondary beams are internally fitted with a support structure. The support structure includes a support beam, support rod one, and support rod two. Each set of secondary beams has two upper and lower support rods two fixed inside, and two lower and upper support rods one fixed inside. This high-load-bearing box-type truss steel structure, with its support structure located inside the box-type truss, provides support from the inside, improving the box-type truss's compressive strength and achieving a high load-bearing capacity. Support rods one and two support the secondary beams, distributing pressure. The support beam connects and supports support rods one and two, serving as the core of the support force and increasing the truss's compressive strength.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figure 1-5This utility model provides a technical solution: a steel structure box truss that is easy to assemble and connect, including a crossbar 1, a first hollow plate 2, a supporting plate 3, a second hollow plate 4, a third hollow plate 5, a first reinforcing rib 6, a second reinforcing rib 7, a first groove 8, a cylindrical block 9, a square block 10, a second groove 11, a fixing plate 12, a movable sleeve 13, an adjusting rod 14, and a limiting plate 15. The crossbar 1 and the first hollow plate 2, which are symmetrically distributed at the four corners, are welded to the inner side of the middle of the crossbar 1. The second hollow plate 4 and the third hollow plate 5 are fixedly connected to the outer sides of the front and rear ends of the crossbar 1, respectively. A limiting connection structure is provided between the second hollow plate 4 and the third hollow plate 5. The connection structure includes a square block 10, a second groove 11, a fixing plate 12, a movable sleeve 13, an adjusting rod 14, and a limiting plate 15. The square block 10 is fixedly connected to the front side of the middle of the left and right ends of the second hollow plate 4.
[0026] To address the limitations of existing steel box truss structures in terms of load-bearing capacity and the inconvenience of rapid assembly and connection, this embodiment employs the following technical solution: Figure 1 , Figure 2 and Figure 5 Workers can first select the appropriate number of steel box trusses according to the building's load-bearing length requirements. Then, they can assemble and connect the steel box trusses to form a steel box truss that meets the length requirements. During assembly, one steel box truss can be placed outside another, so that the second hollow plate 4 at the outer end of one steel box truss is close to the third hollow plate 5 at the outer end of the other steel box truss. Since the inner sides of the front and rear ends of the crossbar 1 are fixedly connected to the second hollow plate 4 and the third hollow plate 5 respectively, and the rear side of the crossbar 1 and the front sides of the left and right ends of the second hollow plate 4 are fixedly connected to cylindrical blocks 9 and square blocks 10 respectively, and the front end of the crossbar 1 has a first groove 8 corresponding to the cylindrical block 9, and the inner sides of the third hollow plate 5 have second grooves 11 corresponding to the square blocks 10, because... This allows the two steel box trusses to be brought close together, so that the cylindrical block 9 and the square block 10 are nested and fitted into the first groove 8 and the second groove 11 respectively, completing the assembly and docking of the steel box truss. Then, the movable sleeve 13 set on the inner side of the middle of the third hollow plate 5 can be rotated, so that the movable sleeve 13 can rotate under the locking limit of the fixed plate 12. Since the left and right ends of the movable sleeve 13 are symmetrically nested and threaded with the adjusting rod 14, and the adjusting rod 14 is fixedly connected to the limiting plate 15 that is nested and locked with the third hollow plate 5, the rotation of the movable sleeve 13 makes it easy for the adjusting rod 14 to drive the limiting plate 15 to move outward, so that the outer end of the limiting plate 15 is nested and locked in the square block 10, achieving the purpose of limiting the square block 10 and the third hollow plate 5, thereby facilitating the rapid assembly and docking of the steel box truss and preventing detachment.
[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4 During the use of this steel structure box truss, a first hollow plate 2 is fixedly connected to the outer side of the middle of the crossbar 1. A first reinforcing rib 6, which is attached to the crossbar 1, is fixedly connected to the inner side of the outer end of the first hollow plate 2. A receiving plate 3, which is fixedly connected to the crossbar 1, is provided on both the front and rear sides of the first hollow plate 2. A second reinforcing rib 7, which is attached to the crossbar 1, is fixedly connected inside the receiving plate 3. Therefore, the connection between the crossbars 1 is guaranteed by the arrangement of the first hollow plate 2, the receiving plate 3, the first reinforcing rib 6, and the second reinforcing rib 7, so that the steel structure box truss has high load-bearing capacity. All the components mentioned above are existing technologies and will not be described in detail here.
