Description

Technical Field

[0001] The utility model relates to the field of steel structure trusses, and specifically relates to a steel structure truss. Background Technique

[0002] Steel structure buildings have increasingly appeared in the public's field of vision and are increasingly accepted and recognized by people. For the specific structural mode of such buildings, when combined with frame members, the corresponding steel structure trusses formed can support between buildings during the construction process, and at the same time provide reliable lateral support and prevent flange from moving to one side.

[0003] When connecting two existing steel structure trusses, most of them are fixedly installed by bolts. After long-term use, due to sun exposure and rain, the bolts are extremely likely to be corroded and rusted, resulting in the disadvantage of reduced stability between the two trusses, which is not conducive to the use of workers. Therefore, we propose a steel structure truss. Content of the Utility Model

[0023] Please refer to Figures 1-4 , a steel structure truss, including a first truss 1, a second truss 2 is arranged on one side of the first truss 1, threaded holes 3 are opened on one side of both the first truss 1 and the second truss 2, a fixed plate 4 is arranged on one side of both the first truss 1 and the second truss 2, connecting plates 5 are fixedly connected to the top and the top of the fixed plate 4, a connecting component is arranged on one side of the connecting plate 5, and the connecting component includes a bolt 6 threadedly connected to the outside of the connecting plate 5. Threaded holes 3 are opened on one side of both the first truss 1 and the second truss 2, and the bolt 6 is adapted to the threaded hole 3. By arranging the connecting component, the fixed plate 4 can be fixedly connected to the outside of the first truss 1 and the second truss 2.

[0024] Furthermore, a housing 7 is fixedly connected to one side of the fixed plate 4, a rotating shaft 8 is rotatably connected to one side of the housing 7, a grip 9 is fixedly connected to one side of the rotating shaft 8, and the material of the grip 9 is rubber. By arranging the rubber grip 9, the comfort of the staff when holding the grip 9 is improved. The rotating shaft 8 extends into the housing 7, and a transmission component is arranged on the outside of the rotating shaft 8. The transmission component includes a worm gear 13 fixedly connected to one end of two threaded sleeves 12, a worm 10 is fixedly connected to one end of the rotating shaft 8, and the worm 10 meshes with the worm gear 13. By arranging the transmission component, the two threaded sleeves 12 can be rotated simultaneously. Two symmetrically distributed horizontal plates 11 are fixedly connected to one side of the inner wall of the housing 7, and the worm 10 is rotatably connected to one side of the inner wall of the housing 7. By rotatably connecting the worm 10 to one side of the inner wall of the housing 7, the worm 10 is more stable when rotating.

[0025] Furthermore, a clamping assembly is provided outside the horizontal plate 11. The clamping assembly includes a threaded sleeve 12 rotatably connected to one side of the horizontal plate 11. One side of the threaded sleeve 12 extends to the other side of the horizontal plate 11. A threaded rod 14 is threadedly connected inside the threaded sleeve 12. By providing the clamping assembly, the first truss 1 and the second truss 2 can be fixedly clamped together.

[0026] Furthermore, a limiting assembly is provided outside the housing 7. The limiting assembly includes a slider 15 provided at one end of the threaded rod 14. A sliding groove 16 is formed on one side of the housing 7. The slider 15 is slidably connected inside the sliding groove 16. A clamping block 17 is fixedly connected to one side of the slider 15. By providing the limiting assembly, the slider 15 can move more stably when moving.

[0027] Working principle: When it is necessary to fixedly connect the first truss 1 and the second truss 2, first align the first truss 1 and the second truss 2. Then place the fixing plate 4 at the connection of the first truss 1 and the second truss 2. At this time, screw the bolt 6 into the threaded holes 3 formed on the first truss 1 and the second truss 2. At this time, the fixing plate 4 can be fixed between the first truss 1 and the second truss 2. Then hold the handle 9 and rotate it. By rotating the handle 9, the rotating shaft 8 and the worm 10 can be driven to rotate. Since the worm 10 is meshed with the worm gear 13, the rotation of the worm 10 can drive the worm gear 13 to rotate. At this time, the worm gear 13 can make the two threaded sleeves 12 rotate simultaneously, and then drive the two threaded rods 14 connected by threads to move towards each other. By the movement of the threaded rod 14, the slider 15 can be driven to slide inside the sliding groove 16, so that the slider 15 moves more stably when moving. By the movement of the slider 15, the two clamping blocks 17 can be driven to move towards each other. At this time, the two clamping blocks 17 move to one side of the inner walls of the first truss 1 and the second truss 2. At this time, the first truss 1 and the second truss 2 can be clamped and fixed. By providing the above structure, it is convenient for the staff to fixedly install the first truss 1 and the second truss 2. The installation effect is tight, avoiding the disadvantages of the traditional use of bolts 6 for installation, where the bolts 6 will rust and corrode after long-term use, resulting in a reduction in the fixing effect. The installation operation is simple, time-consuming is short, reducing the unnecessary workload of the staff, and greatly facilitating the use of the staff.
