Description

Technical Field

[0001] This utility model relates to the field of steel structure canopy technology, specifically a steel structure for a stadium grandstand canopy. Background Technology

[0002] Stadium grandstand canopies are an important component of sports venues. They not only provide spectators with shade, rain protection, and wind shelter, but also enhance the aesthetics and practicality of the venue through their unique structure and design. Stadium grandstand canopies come in various structural types, commonly including steel membrane structures, cable-supported mesh structures, and tensile membrane structures. Each of these structural types has its own characteristics and is suitable for different venue needs and design styles. The choice of materials for stadium grandstand canopies has a significant impact on their performance and service life. Common materials include steel, aluminum alloys, and membrane materials. To ensure the structural stability and safety of stadium grandstand canopies, steel structures are typically used.

[0003] Traditional stadium grandstand canopy steel structures typically use cast-in-place concrete to fix multiple sets of columns to the grandstand. These columns are connected and supported by ring beams, arch trusses, and cable trusses. This cast-in-place method makes it impossible to replace the columns, which, over time, increases the difficulty of replacement and construction when columns are damaged. To address these issues, some stadium grandstand canopy steel structures incorporate flanges at the base of the columns and on the grandstand, connecting them with bolts. This reduces the difficulty of replacement and construction when columns are damaged. However, this method exposes the flanges and bolts to the exterior of the grandstand, making them susceptible to rust due to weather conditions. This not only compromises connection stability but also increases the difficulty of disassembly and assembly. Therefore, a new stadium grandstand canopy steel structure is proposed. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the shortcomings of the existing technology, this utility model provides a steel structure for stadium grandstand canopy to solve the above-mentioned technical problems that not only cannot guarantee connection stability, but also increase the difficulty of disassembly and assembly.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a steel structure for a stadium grandstand canopy, comprising:

[0008] The column, and the arch truss set at the top of the column, with a strut installed between the column and the arch truss, and connecting beams evenly installed on the surface of the arch truss.

[0009] A support base is located directly below the column, and a support rod is installed between the support base and the column. A rotating handle is rotatably connected to the upper surface of the support base, and the rotating handle is locked to the support rod. A connecting cylinder is installed at the bottom of the support base, and an external through hole is evenly opened on the surface of the connecting cylinder. A tapered insert rod is slidably connected to the inner cavity of the external through hole, and a rotating shaft is rotatably connected to the inner cavity of the connecting cylinder. The rotating shaft is coaxially connected to the rotating handle, and a fan-shaped pressure plate is evenly installed on the surface of the rotating shaft. Arc-shaped side plates are evenly added to both sides of the rotating shaft. A return spring is sleeved between the arc-shaped side plate and the tapered insert rod, and a positioning hole is opened at the end of the tapered insert rod.

[0010] A fixed cylinder is located on the outside of the connecting cylinder, and its inner wall is evenly provided with external connecting holes. These external connecting holes correspond to the external through holes, and each external connecting hole has a positioning rod inserted into its inner cavity. The grandstand canopy is supported by columns, arch trusses, bracing trusses, and connecting beams. When installing the columns on the stadium grandstand, the fixed cylinder is first cast and fixed into the stadium grandstand. Then, the column drives the support seat to fit against the top of the fixed cylinder, and the connecting cylinder enters the inner cavity of the fixed cylinder. Rotating the rotating handle on the support seat drives the rotating shaft to rotate within the inner cavity of the connecting cylinder. As the fan-shaped pressure plate rotates with the shaft, it squeezes the arc-shaped side plate and the return spring, causing the arc-shaped side plate to drive the tapered rod along the external through hole into the inner cavity of the external connecting hole. A positioning rod is then inserted on the support seat, causing the positioning rod to descend along the inner wall of the fixed cylinder and insert into the positioning hole. When the fixed cylinder... After the cylinder body is connected to the connecting cylinder, the rotating handle is locked to the support rod. When dismantling the column, first separate the locking connection between the support rod and the rotating handle, then raise the positioning rod along the support base and separate it from the positioning hole. Reset the rotating handle on the support base to separate the fan-shaped pressure plate from the arc-shaped side plate. Under the action of the return spring, the arc-shaped side plate drives the conical rod to reset and separate from the external connecting hole, so that the column can be pulled out along the fixed cylinder body. On the one hand, this not only ensures the stability of the connection but also reduces the difficulty of disassembly and assembly. On the other hand, since the rotating handle is locked to the support rod, the stability of the rotating handle on the support base can be ensured, avoiding vibration and other phenomena that cause the rotating handle to rotate on its own.

[0011] Preferably, limiting protrusions are uniformly installed on the outer surface of the column, and hollow sleeves are slidably connected to the outer surface of the column. The hollow sleeves can move up and down along the outer surface of the column, and the hollow sleeves are tightly fitted with the support base, so that the hollow sleeves provide protection for the structure at the top of the support base.

[0012] Preferably, the inner wall of the hollow sleeve is uniformly provided with limiting grooves, and the shapes of the limiting grooves correspond to those of the limiting protrusions. When the hollow sleeve descends along the outer surface of the column and fits tightly against the support, the hollow sleeve can be rotated on the column to misalign the limiting grooves and the limiting protrusions, thereby ensuring the stability of the hollow sleeve on the support.

[0013] Preferably, each of the support rods is fitted with a limiting rod, and a limiting post is installed at the end of each limiting rod, with the limiting post engaging with the rotating handle. When the hollow sleeve is positioned on the support base, the outer end of the limiting rod fits tightly against the inner wall of the hollow sleeve, thereby ensuring the stability of the engaging connection between the limiting post and the rotating handle.

[0014] Preferably, the end of the return spring is connected to both the inner wall of the connecting cylinder and the surface of the arc-shaped side plate. The arc-shaped side plate can drive the return spring to move towards the inner wall of the connecting cylinder to compress it, and the return spring drives the arc-shaped side plate to perform a reset operation on the inner wall of the connecting cylinder.

[0015] Preferably, the tapered insert corresponds to the position of the external connecting hole, and the positioning hole corresponds to the shape of the positioning insert. The tapered insert can enter the interior of the external connecting hole along the external through hole, and the positioning insert descends along the support base and the fixed cylinder and is inserted into the positioning hole of the tapered insert for connection.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a steel structure for a stadium grandstand canopy, which has the following beneficial effects:

[0018] The steel structure of the stadium grandstand canopy is constructed by first casting and fixing a fixed cylinder into the interior of the stadium grandstand during the installation of the columns. Then, the column drives the support base to fit against the top of the fixed cylinder, and the connecting cylinder enters the inner cavity of the fixed cylinder. Rotating the handle on the support base drives the rotating shaft to rotate within the inner cavity of the connecting cylinder. As the fan-shaped pressure plate rotates with the shaft, it compresses the arc-shaped side plate and the return spring, causing the arc-shaped side plate to drive the tapered insert rod along the outer through hole into the inner cavity of the outer connecting hole. A positioning insert rod is then inserted into the support base, causing the positioning insert rod to descend along the inner wall of the fixed cylinder and insert into the positioning hole. When the fixed cylinder and the connecting cylinder are connected... After connection, the rotating handle is locked to the support rod. When dismantling the column, first separate the locking connection between the support rod and the rotating handle, then raise the positioning rod along the support base and separate it from the positioning hole. Reset the rotating handle on the support base, causing the fan-shaped pressure plate to separate from the arc-shaped side plate. Under the action of the return spring, the arc-shaped side plate drives the conical rod to reset and separate from the external connecting hole, allowing the column to be pulled out along the fixed cylinder. On the one hand, this not only ensures connection stability but also reduces the difficulty of disassembly and assembly; on the other hand, because the rotating handle is locked to the support rod, the stability of the rotating handle on the support base is ensured, preventing vibrations that could cause the rotating handle to rotate on its own.

[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] This utility model provides a technical solution: a steel structure for a stadium grandstand canopy, comprising: (see details) Figure 1 , Figure 3 , Figure 4 , a column 1, and an arch truss 2 set at the top of the column 1, with a strut 3 installed between the column 1 and the arch truss 2, and connecting beams 4 evenly installed on the surface of the arch truss 2.

[0026] A support base 8 is located directly below the column 1, and a support rod 9 is installed between the support base 8 and the column 1. A rotating handle 10 is rotatably connected to the upper surface of the support base 8, and the rotating handle 10 is locked to the support rod 9. A connecting cylinder 13 is installed at the bottom of the support base 8, and an external through hole 14 is evenly opened on the surface of the connecting cylinder 13. A tapered insert rod 18 is slidably connected to the inner cavity of the external through hole 14. A rotating shaft 15 is rotatably connected to the inner cavity of the connecting cylinder 13. The rotating shaft 15 is coaxially connected to the rotating handle 10. A fan-shaped pressure plate 16 is evenly installed on the surface of the rotating shaft 15, and an arc-shaped side plate 17 is evenly added to both sides of the rotating shaft 15. A return spring 20 is sleeved between the arc-shaped side plate 17 and the tapered insert rod 18, and a positioning hole 19 is opened at the end of the tapered insert rod 18.

[0027] A fixed cylinder 21 is located on the outside of the connecting cylinder 13, and the inner wall of the fixed cylinder 21 is evenly provided with external connecting holes 22. The external connecting holes 22 correspond to the positions of the external through holes 14, and the inner cavity of each external connecting hole 22 is provided with a positioning rod 23. The grandstand canopy is supported by columns 1, arch trusses 2, bracing trusses 3, and connecting beams 4. When installing columns 1 on the stadium grandstand, the fixed cylinder 21 is first cast-in-place and fixed into the interior of the stadium grandstand. Then, the column 1 drives the support seat 8 to fit against the top of the fixed cylinder 21. The connecting cylinder 13 enters the inner cavity of the fixed cylinder 21, and the rotating handle 10 on the support seat 8 drives the rotating shaft 15 to rotate within the inner cavity of the connecting cylinder 13. As the fan-shaped pressure plate 16 rotates with the rotating shaft 15, it squeezes the arc-shaped side plate 17 and the return spring 20, causing the arc-shaped side plate 17 to drive the tapered insert 18 along the outer through hole 14 into the inner cavity of the outer connecting hole 22. A positioning insert 23 is then inserted into the support seat 8, causing the positioning insert 23 to descend along the inner wall of the fixed cylinder 21 and insert into the positioning hole 19. After the fixed cylinder 21 is connected to the connecting cylinder 13, the rotating handle 10 is locked to the support rod 9. When the column 1 is removed, the locking connection between the support rod 9 and the rotating handle 10 is first separated, and then the positioning rod 23 is raised along the support seat 8 and separated from the positioning hole 19. The rotating handle 10 is reset on the support seat 8, so that the fan-shaped pressure plate 16 is separated from the arc-shaped side plate 17. Under the action of the reset spring 20, the arc-shaped side plate 17 drives the tapered rod 18 to reset and separate from the external connecting hole 22. The column 1 can then be pulled out along the fixed cylinder 21. On the one hand, this not only ensures the stability of the connection, but also reduces the difficulty of disassembly and assembly. On the other hand, since the rotating handle 10 is locked to the support rod 9, the stability of the rotating handle 10 on the support seat 8 can be ensured, and vibration or other factors can prevent the rotating handle 10 from rotating on its own.

[0028] Please see Figure 2 Limiting protrusions 5 are uniformly installed on the outer surface of the column 1, and hollow sleeves 6 are slidably connected to the outer surface of the column 1. The hollow sleeves 6 can move up and down along the outer surface of the column 1, and the hollow sleeves 6 are tightly fitted with the support base 8, so that the hollow sleeves 6 provide protection for the structure at the top of the support base 8. Limiting grooves 7 are uniformly formed on the inner wall of the hollow sleeves 6, and the shape of the limiting grooves 7 corresponds to that of the limiting protrusions 5. When the hollow sleeves 6 descend along the outer surface of the column 1 and are tightly fitted with the support base 8, the hollow sleeves 6 can be rotated on the column 1 to make the limiting grooves 7 and the limiting protrusions 5 misaligned, thereby ensuring the stability of the hollow sleeves 6 on the support base 8.

[0029] Please see Figure 4Each support rod 9 has a limiting rod 12 inserted on its outer side, and a limiting post 11 is installed at the end of each limiting rod 12. The limiting post 11 is engaged with the rotating handle 10. When the hollow sleeve 6 is on the support base 8, the outer end of the limiting rod 12 fits tightly against the inner wall of the hollow sleeve 6, thus ensuring the stability of the engagement between the limiting post 11 and the rotating handle 10. The end of the return spring 20 is connected to the inner wall of the connecting cylinder 13 and the surface of the arc-shaped side plate 17, respectively. The arc-shaped side plate 17 can drive the return spring 20 to move towards the inner wall of the connecting cylinder 13 for compression. The return spring 20 drives the arc-shaped side plate 17 to perform a reset operation on the inner wall of the connecting cylinder 13. The positional relationship between the tapered insert 18 and the outer connecting hole 22 is corresponding, and the shape of the positioning hole 19 corresponds to that of the positioning insert 23. The tapered insert 18 can enter the interior of the outer connecting hole 22 along the outer through hole 14, and the positioning insert 23 descends along the support base 8 and the fixed cylinder 21 and is inserted into the positioning hole 19 of the tapered insert 18 for connection.

[0030] This scheme provides support for the grandstand canopy through columns 1, arch trusses 2, bracing trusses 3, and connecting beams 4. When installing columns 1 on the stadium grandstand, the fixed cylinder 21 is first cast-in-place and fixed into the interior of the stadium grandstand. Then, the column 1 drives the support seat 8 to fit against the top of the fixed cylinder 21, and the connecting cylinder 13 enters the inner cavity of the fixed cylinder 21. Rotating the rotating handle 10 on the support seat 8 drives the rotating shaft 15 to rotate within the inner cavity of the connecting cylinder 13. As the fan-shaped pressure plate 16 rotates with the rotating shaft 15, it compresses the arc-shaped side plate 17 and the return spring 20, causing the arc-shaped side plate 17 to drive the tapered insert rod 18 along the outer through hole 14 into the inner cavity of the outer connecting hole 22. A positioning insert rod 23 is then inserted into the support seat 8, causing the positioning insert rod 23 to move along the inner wall of the fixed cylinder 21. The lowered insertion is inserted into the positioning hole 19. After the fixed cylinder 21 is connected to the connecting cylinder 13, the rotating handle 10 is locked to the support rod 9. When the column 1 is removed, the locking connection between the support rod 9 and the rotating handle 10 is first separated. Then, the positioning rod 23 is raised along the support seat 8 and separated from the positioning hole 19. The rotating handle 10 is reset on the support seat 8, so that the fan-shaped pressure plate 16 is separated from the arc-shaped side plate 17. Under the action of the reset spring 20, the arc-shaped side plate 17 drives the tapered rod 18 to reset and separate from the outer connecting hole 22. The column 1 can then be pulled out along the fixed cylinder 21. When the hollow sleeve 6 descends along the outer surface of the column 1 and fits tightly against the support seat 8, the hollow sleeve 6 can be rotated on the column 1 to make the position of the limiting groove 7 and the limiting protrusion 5 misaligned.
