Description

Technical Field

[0001] This application relates to the field of truss technology, and in particular to steel structure support trusses with strong torsional resistance. Background Technology

[0002] In modern construction engineering and large-scale equipment manufacturing, steel structures are widely used due to their advantages such as high strength, lightweight, and ease of processing and forming. With the development of construction technology, the height and complexity of building structures are constantly increasing, placing higher demands on the stability and torsional performance of steel structure support systems. Especially when facing dynamic loads such as wind loads and seismic forces, traditional steel structure designs often fail to meet the requirements, easily leading to torsional instability. This not only limits the height and span of the structure but also threatens the safety and durability of the building.

[0003] To improve the torsional resistance of steel structure support systems, various solutions have been implemented in the industry. One common method is to increase the overall stiffness by increasing the cross-sectional dimensions of the components. While effective to some extent, this increases material costs and structural weight. Another approach involves adding stiffeners at joints or employing complex welding techniques, which can enhance local shear resistance to some extent, but also introduces challenges in construction and maintenance. Furthermore, some designs utilize prestressing technology, applying pressure beforehand to counteract the effects of external loads. While effective, this method requires high engineering precision and subsequent management, limiting its widespread practical application.

[0004] While the aforementioned measures have achieved some success in improving the performance of steel structure support systems, they still have significant limitations. First, simply increasing the size or thickness of components cannot fundamentally solve the torsional problem; on the contrary, it may lead to resource waste and increased environmental burden. Second, over-reliance on node reinforcement may exacerbate stress concentration, reducing the overall reliability and service life of the structure. Utility Model Content

[0005] The purpose of this application is to address the problem that increasing the size or thickness of components cannot fundamentally solve the torsion problem, but may instead lead to resource waste and increased environmental burden. Furthermore, over-reliance on node reinforcement may exacerbate stress concentration, reducing the reliability and service life of the entire structure. This application provides a steel structure support truss with strong torsion resistance.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] A high-torsional-resistance steel structure support truss includes an assembly module. One end of the assembly module is symmetrically and fixedly connected to four flange joints arranged in a rectangular pattern. The interior of the assembly module is symmetrically and fixedly connected to transverse connecting rods. A central column is fixedly connected between two transverse connecting rods. Multiple layers of staggered diagonal bracing are fixedly connected to all four sides of the assembly module. Four integrated anti-torsional rods are uniformly and fixedly connected to the middle section of the central column. The four integrated anti-torsional rods are respectively fixedly connected to the four internal corners of the assembly module. A stable triangular support structure is formed between two adjacent diagonal bracing rods.

[0008] By adopting the above technical solution, and by setting up the coordinated use of diagonal braces, central columns, and transverse connecting rods, the load can be distributed by the triangular support structure formed by the staggered diagonal braces when the assembly module is subjected to external torque, thus avoiding damage caused by excessive force on a single point. At the same time, the central column is set as the main axis to bear most of the vertical load, and the force is evenly transferred to the foundation structure of the assembly module through the transverse connecting rods, forming a closed force chain network, which greatly enhances the overall rigidity of the assembly module and its ability to resist torsion.

[0009] Furthermore, a connecting block one is symmetrically fixedly connected to one side of the diagonal brace, and a connecting block two adapted to the connecting block one is fixedly connected to one end of the assembly module. Both the connecting block one and the connecting block two have locking holes at one end, and locking screws are inserted into the locking holes. A locking nut is threaded to one end of the locking screw.

[0010] By adopting the above technical solution, and by setting up the cooperation of locking screw and locking nut, after the pulling locking screw passes through the locking hole through the connecting block two and the connecting block one, the locking nut is tightened to achieve a fixed connection between the diagonal brace and the assembly module. This makes it easy to pull the corresponding number of diagonal braces and the assembly module to achieve a fixed connection according to the actual situation, thereby completing the rapid assembly of the assembly module and effectively improving the practicality of the device.

[0011] Furthermore, a locking ring is fitted onto one end of the locking screw, and the locking ring is installed between the locking nut and the locking hole.

[0012] By adopting the above technical solution and using the locking ring and locking nut together, the contact area between the locking nut and the connecting block is effectively increased, the friction between the locking nut and the connecting block is improved, and the fixation of the diagonal brace and the assembly module is more stable.

[0013] Furthermore, the assembly module has multiple limiting grooves on its outer side, and one end of the diagonal brace is embedded inside the limiting groove.

[0014] By adopting the above technical solution, and by using the combination of the limiting groove and the diagonal brace, it is easy to insert one end of the diagonal brace into the inside of the limiting groove by pulling it. Under the action of gravity, the diagonal brace will come into contact with the inner wall of the limiting groove and be pre-positioned inside the limiting groove, so as to facilitate the subsequent fixed connection of the diagonal brace and the assembly module, thereby improving the practicality of the device.

[0015] Furthermore, four L-shaped steel bars are symmetrically fixedly connected to one end of the assembly module, and the four L-shaped steel bars are respectively installed at the four corners of the assembly module.

[0016] By adopting the above technical solution and using L-shaped steel bars in conjunction with the assembly module, the torsional strength of the assembly module is effectively improved, thus enhancing the practicality of the device.

[0017] Furthermore, the central column is configured as a carbon fiber reinforced plastic column.

[0018] By adopting the above technical solution, the mass of the central column is effectively reduced by using carbon fiber reinforced plastic, thus improving the portability of the device.

[0019] Furthermore, both the assembly module and the diagonal brace are coated with an organosilicon waterproof coating.

[0020] By adopting the above technical solution and setting an organosilicon waterproof coating, the corrosion resistance of the device is effectively improved and the service life of the device is extended.

[0021] Furthermore, the surface of the L-shaped steel strip is coated with a reflective coating.

[0022] By adopting the above technical solution, the reflective coating effectively improves the visibility of L-shaped steel bars in dim environments and enhances the safety of the device.

[0023] In summary, this application includes at least one of the following beneficial effects:

[0024] 1. By using diagonal braces in conjunction with the central column and transverse connecting rods, the load can be distributed by the triangular support structure formed by the staggered diagonal braces when the assembly module is subjected to external torque, thus avoiding damage caused by excessive force at a single point. At the same time, the central column is set as the main axis to bear most of the vertical load, and the force is evenly transferred to the foundation structure of the assembly module through the transverse connecting rods, forming a closed force chain network, which greatly enhances the overall rigidity of the assembly module and its resistance to torsion.

[0025] 2. By using the limiting groove and the diagonal brace together, it is easy to insert one end of the diagonal brace into the inside of the limiting groove through traction. Under the action of gravity, the diagonal brace will come into contact with the inner wall of the limiting groove and be pre-positioned inside the limiting groove, so as to facilitate the subsequent fixed connection of the diagonal brace and the assembly module, thus improving the practicality of the device.

[0031] The following is in conjunction with the appendix Figure 1 —3 provides further detailed description of this application.

[0032] This application discloses steel structure support trusses with strong torsional resistance.

[0033] Reference Figure 1 - Figure 3 The steel structure support truss with strong torsional resistance includes an assembly module 1. Four flange joints 2 are symmetrically fixedly connected to one end of the assembly module 1. The four flange joints 2 are arranged in a rectangle. Transverse connecting rods 3 are symmetrically fixedly connected inside the assembly module 1. A central column 4 is fixedly connected between two transverse connecting rods 3. Multi-layer staggered diagonal braces 5 are fixedly connected to all four sides of the assembly module 1. Four integrated anti-torsion rods 6 are uniformly fixedly connected to the middle section of the central column 4. The four integrated anti-torsion rods 6 are fixedly connected to the four corners inside the assembly module 1 respectively. A stable triangular support structure is formed between two adjacent diagonal braces 5.

[0034] In use, firstly, two adjacent diagonal braces 5 are set to form a stable triangular support structure on the four sides of the assembly module 1. Then, multiple assembly modules 1 are aligned end to end by pulling and quickly fixed and connected through flange joints 2. At the same time, the central column 4 and the transverse connecting rod 3 are used in conjunction to evenly transfer the vertical force of the assembly module 1 to the base structure of the assembly module 1, thereby stacking and fixing multiple assembly modules 1 in sequence until the required height is reached.

[0035] Then, when the assembly module 1 is subjected to external torque, the triangular support structure composed of the diagonal braces 5 arranged on the four sides of the assembly module 1 can effectively distribute the load and avoid damage caused by excessive force on a single point. At the same time, the central column 4 acts as the main shaft to bear most of the vertical load, and the force is evenly transmitted to the foundation structure of the assembly module 1 through the transverse connecting rod 3, forming a closed force chain network, which greatly enhances the overall rigidity and resistance to torsion of the assembly module 1.

[0036] Reference Figure 1 - Figure 3 One side of the diagonal brace 5 is symmetrically fixedly connected to a connecting block 7, and one end of the assembly module 1 is fixedly connected to a connecting block 8 that is compatible with the connecting block 7. One end of both the connecting block 7 and the connecting block 8 is provided with a locking hole 9. A locking screw 10 is inserted into the locking hole 9, and a locking nut 11 is threaded to one end of the locking screw 10.

[0037] When using the assembly module 1, when it is transported to the installation area, the connecting block 7 and the connecting block 8 are aligned by manually pulling the diagonal brace 5 according to the actual situation. Then, one end of the locking screw 10 is pulled through the locking hole 9 and passes through the connecting block 8 and the connecting block 7 in sequence. The locking nut 11 is then tightened so that the locking nut 11 moves towards the connecting block 7 along the direction of the locking screw 10, and the diagonal brace 5 is fixedly connected to the assembly module 1. This allows the corresponding number of diagonal braces 5 to be pulled to fix the assembly module 1 according to the actual situation, thereby completing the rapid assembly of the assembly module 1 and effectively improving the practicality of the device.

[0038] Reference Figure 1 - Figure 3 One end of the locking screw 10 is fitted with a locking ring 12, which is installed between the locking nut 11 and the locking hole 9.

[0039] In use, when the locking nut 11 is tightened to form a threaded connection with the locking screw 10, and the diagonal brace 5 is pushed to form a fixed connection with the assembly module 1, the locking nut 11 pushes the locking ring 12 to abut against the connecting block 7 along the length of the locking screw 10. This effectively increases the contact area between the locking nut 11 and the connecting block 7, improves the friction between the locking nut 11 and the connecting block 7, and makes the fixation of the diagonal brace 5 and the assembly module 1 more stable.

[0040] Reference Figure 1 - Figure 3 Multiple limiting grooves 13 are provided on the outer side of the assembly module 1, and one end of the diagonal brace 5 is embedded in the inside of the limiting groove 13.

[0041] In use, when the traction brace 5 drives the connecting block 7 to align with the connecting block 8, one end of the traction brace 5 is manually pulled into the interior of the limiting groove 13. Under the action of gravity, one end of the traction brace 5 comes into contact with the inner wall of the limiting groove 13, thus pre-positioning the traction brace 5 inside the limiting groove 13. This facilitates the subsequent fixed connection of the traction brace 5 and the assembly module 1, improving the practicality of the device.

[0042] Reference Figure 1 - Figure 3 Four L-shaped steel bars 14 are symmetrically fixedly connected to one end of the assembly module 1, and the four L-shaped steel bars 14 are respectively installed at the four corners of the assembly module 1.

[0043] When the assembly module 1 is subjected to external torque during use, the assembly module 1 transmits the force to the L-shaped steel bar 14, and the L-shaped steel bar 14 bears part of the force at the four corners of the assembly module 1, thereby improving the torsional strength of the assembly module 1 and improving the practicality of the device.

[0044] Reference Figure 1 - Figure 2 The central column 4 is set as a carbon fiber reinforced plastic column.

[0045] In use, the overall weight of the device is effectively reduced by setting the central column 4 to carbon fiber reinforced plastic, which improves the portability of the device.

[0046] Reference Figure 1 - Figure 3 Both the assembly module 1 and the diagonal brace 5 are coated with an organosilicon waterproof coating.

[0047] During use, by coating the surfaces of the assembly module 1 and the diagonal brace 5 with an organic silicone waterproof coating, a waterproof protective layer is formed on the surfaces of the assembly module 1 and the diagonal brace 5, which effectively improves the corrosion resistance of the assembly module 1 and the diagonal brace 5 and extends the service life of the device.

[0048] Reference Figure 1 - Figure 3 The surface of the L-shaped steel strip 14 is coated with a reflective coating.

[0049] When in use, when light shines on the surface of the L-shaped steel strip 14, the reflective coating reflects the light, thereby reducing the possibility of foreign objects colliding with and damaging the assembly module 1 in dim environments, thus improving the safety of the device.

[0050] The implementation principle of the high torsional steel structure support truss in this embodiment is as follows: First, a stable triangular support structure is formed on the four sides of the assembly module 1 by setting two adjacent diagonal braces 5. Then, multiple assembly modules 1 are aligned end to end by traction and quickly fixed and connected by flange joints 2. At the same time, the cooperation between the central column 4 and the transverse connecting rod 3 is set to evenly transfer the vertical force of the assembly module 1 to the foundation structure of the assembly module 1, thereby stacking and fixing multiple assembly modules 1 in sequence until the required height is reached.

[0051] Then, by manually pulling one end of the diagonal brace 5 into the interior of the limiting groove 13, and under the action of gravity, one end of the diagonal brace 5 comes into contact with the inner wall of the limiting groove 13, so that the diagonal brace 5 is pre-positioned inside the limiting groove 13.

[0052] Next, by manually pulling the diagonal brace 5, the connecting block 7 is aligned with the connecting block 8. Then, one end of the locking screw 10 is pulled through the locking hole 9 and passes through the connecting block 8 and the connecting block 7 in sequence. The locking nut 11 is then tightened, so that the locking nut 11 moves towards the connecting block 7 along the direction of the locking screw 10. This causes the diagonal brace 5 to form a fixed connection with the assembly module 1. This allows the corresponding number of diagonal braces 5 to be pulled and fixedly connected with the assembly module 1 according to the actual situation, thereby completing the rapid assembly of the assembly module 1.

[0053] When the assembly module 1 is subjected to external torque, the triangular support structure composed of the diagonal braces 5 arranged on the four sides of the assembly module 1 can effectively distribute the load and avoid damage caused by excessive force on a single point. At the same time, the central column 4 acts as the main shaft to bear most of the vertical load, and the force is evenly transmitted to the foundation structure of the assembly module 1 through the transverse connecting rod 3, forming a closed force chain network, which greatly enhances the overall rigidity of the assembly module 1 and its ability to resist torsion.
