Description

Technical Field

[0001] This utility model relates to the field of temporary grandstand technology, and specifically to a temporary grandstand module. Background Technology

[0002] Fixed grandstands are a common spectator facility for various sporting events, cultural performances, and large gatherings. However, fixed grandstands have drawbacks such as high construction costs and low utilization rates. Therefore, temporary grandstands that can be assembled and disassembled have emerged and are gradually being widely promoted and applied.

[0003] For example, patent number CN213539853U discloses a modular temporary grandstand that is easy to assemble and disassemble. It includes main trusses, secondary trusses, and multiple rows of spaced support rods. Multiple main trusses form a support frame with an inclined surface. Secondary trusses are installed between adjacent rows of corresponding main trusses. The main trusses have slots, and the secondary trusses have plug-in columns that mate with the slots. Railings are fixed around the support frame, and the bottom of the railings is fixedly connected to the main and secondary trusses. In this structure, because the secondary and main trusses are connected by plug-in columns, firstly, the slots are small, making it difficult to insert the plug-in columns during installation, resulting in inconvenient installation. Secondly, during processing, slot seats need to be welded to the sides of the main trusses first, and then slots need to be drilled into the slot seats. The secondary trusses also need to be drilled before welding the plug-in columns, making the structure and process complex. The slots also require high precision, making processing difficult. Furthermore, the outer frame of the railing structure needs to be bent before welding, making the processing complex. Utility Model Content

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, the beneficial effects that at least one technical solution adopted in the embodiments of this specification can achieve include at least:

[0019] 1) The secondary truss is detachably connected to the main truss via a lug structure. The lugs are L-shaped and bent downwards, allowing them to be directly hooked onto the opening of the square tube above the vertical square tube. Compared to the traditional method of using plug-in columns and slots, this avoids the problem of difficulty in inserting plug-in columns due to small slots, making the installation process smoother and more efficient, and greatly saving installation time and labor costs. For the secondary truss, only angle steel plates need to be fixed on both sides of the upper end of the rectangular frame to form lugs, eliminating the need to drill holes and weld plug-in columns on the secondary truss as in existing technologies. The main truss also does not need to weld slot seats first and then drill holes to process slots, simplifying the processing technology, reducing the requirements for processing precision, thereby reducing processing difficulty and manufacturing costs.

[0020] 2) The connecting rods symmetrically arranged at the bottom of the rectangular outer frame of the fence are connected to the main truss through multiple pins. The pin connection method is simple to operate and helps to improve the assembly efficiency of the temporary grandstand module. The fence is formed by welding square tubes to form a rectangular outer frame. Compared with the complex process of bending and welding the outer frame of traditional railings, the square tube welding process is simpler and more direct, without the need for bending. It is also simpler and more convenient to punch holes in the square tubes. The process is simple and less difficult, which improves production efficiency. Attached Figure Description

[0036] Combination Figures 1-8 As shown, this utility model provides a temporary grandstand module, including symmetrically arranged and spaced main trusses 1 and multiple secondary trusses 2 detachably installed between two main trusses 1. The secondary trusses 2 are detachably connected to the main trusses 1 via a lug structure. The lug structure includes lugs 21 symmetrically fixed on both sides of the upper end of the secondary trusses 2. The lugs 21 are L-shaped and bent downwards. The main trusses 1 have square tube openings 101 at the top of the vertical square tubes 11, and the lugs 21 are hooked at the square tube openings 101. The main trusses 1 are stepped, and a fence 3 is fixed on the stepped platform of the main trusses 1. The fence 3 includes a rectangular outer frame 31 formed by welding multiple square tubes. Connecting rods 32 are symmetrically arranged at the bottom of the rectangular outer frame 31, and the connecting rods 32 are connected to the main trusses 1 via multiple pins.

[0037] In this structure, the secondary truss is detachably connected to the main truss via a lug structure. The lugs can be directly hooked onto the openings of the vertical square tubes. Compared to the traditional method of using plug-in posts and slots, this avoids the problem of difficulty in inserting the plug-in posts due to the small size of the slots, making the installation process smoother and more efficient, and greatly saving installation time and labor costs. For the secondary truss, only the lugs need to be welded to both sides at the top, eliminating the need to drill holes in the secondary truss before welding the plug-in posts as in existing technologies. This simplifies the process and makes processing easier. The main truss also eliminates the need to weld the slot seats first and then drill holes to process the slots, simplifying the processing technology, reducing the requirements for processing precision, thereby reducing processing difficulty and manufacturing costs. In addition, the connecting rods symmetrically arranged at the bottom of the rectangular outer frame of the fence are connected to the main truss via multiple pins. The pin connection method is simple to operate and helps to improve the assembly efficiency of the temporary grandstand modules. The fence uses square tubes welded to form a rectangular outer frame. Compared to the complex process of bending and welding the outer frame of traditional railings, the square tube welding process is simpler and more direct, eliminating the need for bending, simplifying the process and reducing processing difficulty.

[0038] In some embodiments, such as Figure 5As shown, the secondary truss 2 includes a rectangular frame 22, which is formed by welding multiple square tubes. Angle steel plates are fixed to both sides of the upper end of the rectangular frame 22 to form lugs 21. These lugs are formed by welding angle steel plates, which is convenient for processing. A central support rod 23 is provided in the middle of the rectangular frame 22, and angle steel rods 24 are symmetrically arranged on both sides of the central support rod 23. Both the central support rod 23 and the angle steel rods 24 are located inside the rectangular frame 22. Through the cooperation of the central support rod 23 and the angle steel rods 24, this internal support structure effectively enhances the overall strength and stability of the secondary truss, ensuring that it is not easily deformed or damaged when bearing the weight of the audience or other external forces.

[0039] In some embodiments, such as Figure 6 As shown, the main truss 1 includes a bottom horizontal bar 12 and multiple vertical square tubes 11 fixed to the bottom horizontal bar 12 with progressively increasing heights. A transverse support rod 13 is fixed between adjacent vertical square tubes 11, and the multiple transverse support rods 13 are arranged in a stepped manner. An oblique support rod 14 is installed between adjacent vertical square tubes 11; and / or, a vertical support rod 15 is installed between the transverse support rod 13 and the bottom horizontal bar 12. A vertical connecting rod 16 is provided at one end of the main truss 1. The vertical connecting rod 16 is a circular rod, with a column 161 at its upper end and a sleeve 162 at its lower end. Transverse support rods 13 and oblique support rods 14 are installed between the vertical connecting rod 16 and its adjacent vertical square tubes 11.

[0040] In this embodiment, there are three vertical square tubes 11 and three horizontal support rods 13. An oblique support rod 14 is installed between the second vertical square tube 11 (counting from right to left) and the third vertical square tube 11, and an oblique support rod 14 is installed between the third vertical square tube 11 and the vertical connecting rod 16. A vertical support rod 15 is installed between the first horizontal support rod 13 (the lowest in height) and the bottom horizontal bar 12. Through the cooperation of the oblique support rods 14 and the horizontal support rods 13, the main truss forms a stable support system, enhancing the overall load-bearing capacity of the temporary grandstand. The vertical connecting rod 16 is mainly used to connect two adjacent main trusses 1. The sleeve 162 on the current main truss 1 can be inserted into the column 161 of the next main truss 1, facilitating the connection and assembly of components and improving the assembly efficiency of the temporary grandstand.

[0041] In some embodiments, such as Figure 7As shown, multiple round tubes 33 are installed at intervals along a straight line inside the rectangular outer frame 31, and the rectangular outer frame 31 is provided with insertion holes 34 for the round tubes 33 to be inserted; decorative cover plates 35 are installed on both sides of the upper end of the rectangular outer frame 31. In the prior art, the railing outer frame adopts a complex process of bending and then welding round tubes. In this embodiment, the rectangular outer frame 31 adopts a method of welding multiple square tubes, which eliminates the need for bending, simplifies the process, and punching insertion holes 34 on square tubes is easier than punching holes on round tubes, thus reducing the processing difficulty.

[0042] In some embodiments, such as Figure 4 and Figure 6 As shown, the vertical square tube 11 and the vertical connecting rod 16 are provided with connecting seats 17 for connecting to the connecting rod 32. In this embodiment, three railings 3 are installed on the main truss 1, and each connecting rod 32 is connected to the main truss 1 by two pins. Since the distance between the first horizontal support rod 13 (counting from right to left) and the bottom horizontal bar 12 is small, the connecting rod 32 is connected to the bottom horizontal bar 12 and the horizontal support rod 13; since the distance between the other two horizontal support rods 13 and the bottom horizontal bar 12 is large, connecting seats 17 need to be added, and the connecting rod 32 is connected to the horizontal support rod 13 and the connecting seat 17.

[0043] In some embodiments, such as Figure 5 , Figure 6 and Figure 8 As shown, a first support plate 25 is provided on one side of the upper end of the secondary truss 2, and a second support plate 26 is provided on the other side of its lower end. The first support plate 25 and the second support plate 26 are used to support the limiting platform 4. When the platform 4 is installed, the platform 4 is supported between the main truss 1, the first support plate 25 of the current secondary truss 2, and the second support plate 26 of the subsequent secondary truss 2. A U-shaped snap-fit ​​18 is fixed on the stepped platform of the main truss 1. The U-shaped snap-fit ​​18 is used to snap the frame of the limiting platform 4 to prevent the platform 4 from shifting and to ensure structural stability.

In particular, the descriptions of the embodiments described later are relatively simple, and relevant parts can be referred to the descriptions of the foregoing embodiments.

[0045] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application.
