Description

Technical Field

[0001] This application relates to the field of support truss technology, and in particular to a steel structure support truss with anti-torsion function. Background Technology

[0002] A truss is a planar or spatial structure composed of straight bars, typically with triangular units. Truss members mainly bear axial tension or compression, thus making full use of the strength of the material. When the span is large, it can save material compared to a solid beam, reduce its self-weight, and increase its stiffness.

[0003] Currently, the members of the truss are only fixed together by bolts for torsional resistance. When the truss is working at height, the stability of the truss will be reduced by external factors such as gravity or wind. At the same time, when the truss is subjected to heavy weight, its torsional resistance cannot be guaranteed, and the bolts are prone to breakage due to excessive force. This not only compromises safety but also shortens the service life of the truss. Summary of the Invention

[0018] like Figures 1-9 As shown, this embodiment of the invention provides a steel structure support truss with anti-torsion function, which includes a truss body and multiple anti-torsion devices. In practical applications, the number of anti-torsion devices is set according to the size of the truss body.

[0019] Continue to refer to Figure 1 As shown, the truss body includes two single trusses 1 and crossbeams 2. The two single trusses 1 are arranged in parallel and connected by several crossbeams 2. Each single truss 1 includes horizontal members 11, vertical members 12, and diagonal members 13. The two horizontal members 11 are arranged in parallel and connected by several vertical members 12. A diagonal member 13 is connected between every two adjacent vertical members 12. Multiple anti-torsion devices are spaced apart on the truss body. In practical applications, the anti-torsion devices improve the stability of the truss during high-altitude operations, ensure the safety performance of the truss, and extend the service life of the truss.

[0020] like Figure 9 As shown, the anti-torsion device includes a support mechanism 3 and multiple fixing mechanisms 4. Multiple fixing mechanisms 4 are connected to the support mechanism 3, and each fixing mechanism 4 is connected to a corresponding diagonal member 13 or crossbeam 2. In practical applications, the diagonal member 13 and crossbeam 2 are connected by the support mechanism 3 and fixing mechanisms 4 to improve the connection strength between the members of the truss body, thereby improving the torsional resistance of the truss body, significantly enhancing the stability of the truss during high-altitude operations, ensuring the safety performance of the truss, and extending the service life of the truss.

[0021] This invention provides a steel structure support truss with anti-torsion function, comprising a truss body and multiple anti-torsion devices. The truss body includes two single trusses 1 and crossbeams 2. The two single trusses 1 are arranged in parallel and connected by several crossbeams 2. Each single truss 1 includes a horizontal member 11, a vertical member 12, and a diagonal member 13. The two horizontal members 11 are arranged in parallel and connected by several vertical members 12. A diagonal member 13 is connected between every two adjacent vertical members 12. Multiple anti-torsion devices are spaced apart on the truss body. Each anti-torsion device includes a support mechanism 3 and multiple fixing mechanisms 4. Multiple fixing mechanisms 4 are connected to the support mechanism 3, and each fixing mechanism 4 is connected to a corresponding diagonal member 13 or crossbeam 2. In practical applications, the diagonal brace 13 and the crossbeam 2 are connected by the support mechanism 3 and the fixing mechanism 4 to improve the connection strength between the members of the truss body, thereby improving the torsional resistance of the truss body, greatly enhancing the stability of the truss in high-altitude operations, ensuring the safety performance of the truss, and extending the service life of the truss.

[0022] like Figure 2 and Figure 3As shown, the fixing mechanism 4 includes a first fixing clip 41, a second fixing clip 42, and a fixing structure 43. The first end of the first fixing clip 41 and the first end of the second fixing clip 42 are hinged together. The first fixing clip 41 and the second fixing clip 42 can be fastened onto the diagonal brace 13 or the crossbeam 2. After the first fixing clip 41 and the second fixing clip 42 are fastened together, the fixing structure 43 can fix the second end of the first fixing clip 41 and the second fixing clip 42. During the installation of the anti-torsion device, the first fixing clip 41 and the second fixing clip 42 are fastened onto the diagonal brace 13 or the crossbeam 2, and then the first fixing clip 41 and the second fixing clip 42 are fixed by the fixing structure 43. The installation is simple and highly reliable. Furthermore, by releasing the fixing of the first fixing clip 41 and the second fixing clip 42, the anti-torsion device can be removed from the truss body, ensuring that the anti-torsion device can be reused.

[0023] like Figures 4-8As shown, the fixing structure 43 includes a plug-in assembly 431, a first compression spring 432, a plug rod 433, a snap-fit ​​rod 434, and a snap-fit ​​assembly 435. The snap-fit ​​assembly 435 is disposed at the upper end of the second fixing clamp 42. The second end of the first fixing clamp 41 is fixed with a plurality of outwardly extending first protrusions 411 at intervals. The second end of the second fixing clamp 42 is fixed with a plurality of second protrusions 421 at intervals that can engage with the first protrusions 411. Each first protrusion 411 and each second protrusion 421 has a mounting hole, and each mounting hole is coaxially arranged. Except for the mounting holes of the first protrusions 411 at the uppermost and lowermost ends of the first fixing clamp 41, each other mounting hole contains a first compression spring 432. Each first compression spring 432 is fixed with a plug rod 433. When the first compression spring 432 is in its natural state, each plug rod 433 is located in the corresponding mounting hole. The first end of the plug-in assembly 431 is located at the upper end of the first fixing clip 41, and the plug-in assembly 431 is rotatably connected to the mounting hole of the first boss 411 at the uppermost end of the first fixing clip 41. The snap-fit ​​rod 434 is fixed to the first end of the plug-in assembly 431. The rotation of the plug-in assembly 431 can drive the snap-fit ​​rod 434 to rotate, so that the snap-fit ​​rod 434 can snap into the snap-fit ​​assembly 435. At the same time, when the plug-in assembly 431 rotates, the second end of the plug-in assembly 431 moves down to press down on the adjacent plug rod 433, so that the plug rod 433 can be inserted into the mounting hole below and press down on the plug rod 433 below it. When it is necessary to connect the fixing mechanism 4 and the truss body, first fasten the first fixing clip 41 and the second fixing clip 42 in the designated position, then rotate the plug-in assembly 431. During the rotation of the plug-in assembly 431, the second end of the plug-in assembly 431 moves down and presses down on the adjacent plug rod 433, so that the plug rod 433 can be inserted into the mounting hole below and press down on the plug rod 433 below it, thereby ensuring that each plug rod 433 can be inserted into the mounting hole below it, thereby achieving the fixation between the first boss 411 and the second boss 421; at the same time, the plug-in assembly... Rotation of component 431 causes the locking rod 434 to rotate, allowing it to engage with locking component 435, thereby securing the insertion component 431 and preventing it from detaching from the adjacent insertion rod 433. When the fixing mechanism 4 needs to be removed from the truss body, the locking rod 434 is first removed from the locking component 435. Then, each insertion rod 433 can be reset under the action of the first compression spring 432. Finally, the first fixing clip 41 and the second fixing clip 42 are removed, thus completing the removal of the fixing mechanism 4. The fixing mechanism 4 of this application is simple to assemble and disassemble and highly efficient, and it also allows for the reuse of the anti-torsion device.

[0024] Continue to refer to Figure 6As shown, the plug-in assembly 431 includes a rotating head 4311, a plug-in rod 4312, and a sliding rod 4313. The rotating head 4311 is located at the upper end of the first fixing clamp 41, and the outer diameter of the rotating head 4311 is larger than the diameter of the mounting hole. The snap-fit ​​rod 434 is fixed to the rotating head 4311. One end of the plug-in rod 4312 is connected to the rotating head 4311, and the other end of the plug-in rod 4312 extends into the mounting hole of the first boss 411 at the uppermost end of the first fixing clamp 41. The side wall of the mounting hole of the first boss 411 at the uppermost end of the first fixing clamp 41 has two symmetrically arranged spiral grooves 411a. Two sliding rods 4313 are symmetrically fixed on the plug-in rod 4312, and the other ends of the two sliding rods 4313 are respectively engaged in the spiral grooves 411a at corresponding positions, and each sliding rod 4313 can slide along the spiral groove 411a at the corresponding position. Specifically, after the first fixing clip 41 and the second fixing clip 42 are engaged in the designated position, the rotating head 4311 is rotated. The rotation of the rotating head 4311 drives the insertion rod 4312 to rotate, and the rotation of the insertion rod 4312 drives the two sliding rods 4313 to rotate, so that the two sliding rods 4313 slide along the spiral grooves 411a at the corresponding positions, thereby ensuring that the rotating head 4311 can move downward while rotating, thereby pressing down on the insertion rod 433.

[0025] Continue to refer to Figure 8As shown, the snap-fit ​​assembly 435 includes a snap-fit ​​block 4351, a stop block 4352, a first stop rod 4353, a second stop rod 4354, and a second compression spring 4355. The snap-fit ​​block 4351 is fixed to the upper end of the second fixing clamp 42. A U-shaped groove 4351a is formed on the snap-fit ​​block 4351 for the snap-fit ​​rod 434 to be inserted. A first blind hole 4351b is formed on the snap-fit ​​block 4351, located above and communicating with the U-shaped groove 4351a. A snap-fit ​​groove 4351c is formed on the snap-fit ​​block 4351, located below and communicating with the U-shaped groove 4351a. The stop block 4352 is disposed at the upper end of the snap-fit ​​block 4351. The first end of the first stop rod 4353 is connected to the stop block 4352, and the second end of the first stop rod 4353 extends into the first blind hole 4351b. The second stop rod 4354 is connected to the end of the first stop rod 4353 that is away from the stop block 4352. The end of the second stop rod 4354 that contacts the locking rod 434 is provided with an inclined surface. The second compression spring 4355 is sleeved on the first stop rod 4353, one end of the second compression spring 4355 is connected to the first blind hole 4351b, and the other end of the second compression spring 4355 is connected to the second stop rod 4354; when the second compression spring 4355 is in its natural state, the end of the second stop rod 4354 that is away from the first stop rod 4353 is located in the locking groove 4351c. In practical applications, the rotation of the plug-in assembly 431 drives the locking rod 434 to rotate. Since the end of the second stop 4354 that contacts the locking rod 434 has an inclined surface, continued rotation of the locking rod 434 pushes the second stop 4354 away from the locking groove 4351c. When the locking rod 434 rotates into the U-shaped groove 4351a, the second stop 4354, under the force of the second compression spring 4355, pops out and locks into the locking groove 4351c, blocking the locking rod 434 and preventing it from... The snap-fit ​​rod 434 disengages from the U-shaped groove 4351a, thereby securing the plug-in assembly 431. When it is necessary to release the plug-in assembly 431, the stop block 4352 is lifted to the end away from the snap-fit ​​groove 4351c. The rise of the stop block 4352 causes the first stop rod 4353 to rise, and the first stop rod 4353 causes the second stop rod 4354 to disengage from the snap-fit ​​groove 4351c, thereby eliminating the obstruction to the snap-fit ​​rod 434 and releasing the fixation of the plug-in assembly 431. The structure is simple and the operation is highly efficient.

[0026] In practical applications, the support mechanism 3 includes a support block 31 and multiple support components 32. The length of the support components 32 is adjustable. One end of each support component 32 is connected to the support block 31, and the other end of each support component 32 is connected to a fixing mechanism 4. When installing the anti-torsion device, the length of the support component 32 can be adjusted according to the dimensions of the truss body to improve the applicability of the anti-torsion device. At the same time, the adjustable length of the support component 32 allows the length of the support component 32 to be adjusted to the shortest possible length when transporting the anti-torsion device, thereby reducing the volume of the anti-torsion device and facilitating its transportation.

[0027] Continue to refer to Figure 9 As shown, the support assembly 32 includes a first support rod 321, a second support rod 322, and a fixing bolt 323. One end of the first support rod 321 is connected to the support block 31, and the first support rod 321 is sleeved on the second support rod 322, allowing the first support rod 321 and the second support rod 322 to slide relative to each other. The end of the second support rod 322 facing away from the first support rod 321 is connected to the fixing mechanism 4. A threaded hole is provided on the first support rod 321. The fixing bolt 323 passes through the threaded hole and abuts against the second support rod 322. In practical applications, when it is necessary to adjust the length of the support assembly 32, first rotate the fixing bolt 323 so that the fixing bolt 323 faces away from the second support rod 322, then slide the second support rod 322 to the required length, and then rotate the fixing bolt 323 to make the second support rod 322 abut against the second support rod 322. The length adjustment is simple and efficient.
