Description

Technical Field

[0001] This utility model relates to the field of truss technology, specifically a prefabricated truss for temporary stage construction. Background Technology

[0002] A truss is a structure made up of members connected to each other at both ends by hinges. It is mostly made of metal rods connected by welding, riveting or screws. A truss is a planar or spatial structure composed of straight rods and generally has triangular units. The truss members mainly bear axial tension or compression, so as to make full use of the strength of the material. When the span is large, it can save materials compared with solid beams, reduce self-weight and increase rigidity. Trusses are required for the construction of temporary stages.

[0003] A search revealed a patent, CN208965882U, which discloses a stage truss comprising a truss body in the shape of a cuboid. The truss body is divided into a head unit, a middle unit, and a tail unit connected sequentially. Reinforcing support frames are provided at the upper, lower, front, and rear ends of the head and tail units. The truss body has at least one middle unit, and reinforcing support tubes are provided at its upper, lower, front, and rear ends. This utility model stage truss incorporates corresponding reinforcing structures, thereby strengthening its structure and improving its wind and torsional resistance. This results in a more ideal structural stability and ensures the safety of the stage truss during use, effectively reducing potential safety hazards.

[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings:

[0005] The trusses in the aforementioned comparative documents require a large number of fastening bolts to connect and install the end connecting frames between the two trusses when assembling the stage. This makes the construction and dismantling of the temporary stage cumbersome and reduces the efficiency of the construction or dismantling of the temporary stage. Therefore, there is an urgent need in the field to improve the prefabricated trusses for the construction of temporary stages in order to solve the defects of the prior art. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a prefabricated truss for temporary stage construction, which improves the assembly and disassembly efficiency of trusses during temporary stage construction.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated truss for temporary stage construction, comprising several main load-bearing pipes connected together, and an assembly for assembling two trusses. The assembly includes two plug-in columns connected together and adapted to the interior of both ends of the main load-bearing pipes. Each plug-in column has an opening at its opposite end, and an elastic element is provided inside the opening. A limiting rod adapted to the elastic element passes through the side of the plug-in column, and a through opening communicating with the opening is provided on the side of the plug-in column. Limiting holes adapted to the ends of the limiting rods are provided on the sides of both ends of the main load-bearing pipes, and the elastic element supports the limiting rods.

[0008] Preferably, a hollow column is provided inside the opening, the elastic element is located inside the hollow column, and one end of the limiting rod is fixedly connected to a limiting plate located inside the hollow column for limiting the limiting rod.

[0009] Preferably, a first threaded step is provided on one side of the hollow column, and a fixing ring adapted to the limiting plate is threadedly connected to the side of the first threaded step.

[0010] Preferably, the assembly further includes a polygonal snap-fit ​​ring, on both sides of which a connecting post is fixedly connected, and each of the two snap-fit ​​posts has a second threaded step adapted to the connecting post at its opposite ends.

[0011] Preferably, the inner wall of the opening is provided with a insertion groove communicating with the outside, and an insertion strip is inserted into the insertion groove, and the hollow column is fixedly connected to one side of the insertion strip.

[0012] Preferably, there are multiple hollow columns, all of which are fixedly connected to one side of the connector strip.

[0013] Preferably, the inner sidewalls at both ends of the main bearing tube and the end of the limiting rod are provided with matching compression angles, and the end of the insertion post is provided with a guide angle.

[0014] To address the shortcomings of existing technologies, this utility model provides a prefabricated truss for temporary stage construction, overcoming these deficiencies. The beneficial effects of this utility model are as follows:

[0015] 1. In this utility model, the plug-in column and the main bearing tube are plugged in. The limiting rod is pushed by the tension of the elastic element to insert one end of the limiting rod into the limiting hole, thus completing the assembly between the two trusses. When it is necessary to disassemble the two trusses, several limiting rods are pressed into the through hole at the same time by a tool. When the limiting rod is disengaged from the limiting hole, the two trusses can be separated, thereby improving the assembly and disassembly efficiency between trusses during the construction of a temporary stage.

[0016] 2. In this utility model, a connector strip is inserted into the connector groove, and a hollow column is fixedly connected to the connector strip. The fixing ring is threadedly connected to the first threaded step position, which facilitates the assembly of the whole device.

[0017] 3. In this utility model, two plug-in columns are threadedly connected to the side of the connecting column, and the setting of the snap ring makes it easy to replace the plug-in columns according to different assembly conditions, thereby improving the applicability of the overall truss during assembly.

[0027] 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.

[0028] Please see Figures 1-6 A prefabricated truss for temporary stage construction includes several main load-bearing pipes 1 connected together, and an assembly 2 for assembling two trusses. The assembly 2 includes two plug-in posts 3 connected together and adapted to the interior of both ends of the main load-bearing pipes 1. Each plug-in post 3 has an opening 7 at its opposite end. An elastic element 4 is provided inside the opening 7. A limiting rod 5 adapted to the elastic element 4 passes through the side of the plug-in post 3. A through opening 6 communicating with the opening 7 is provided on the side of the plug-in post 3. Limiting holes 8 adapted to the ends of the limiting rods 5 are provided on the sides of both ends of the main load-bearing pipes 1. The elastic element 4 supports the limiting rods 5.

[0029] Specifically, when a temporary stage needs to be erected, multiple trusses of suitable sizes are required, and several trusses need to be assembled. During the assembly of the trusses, one of each of two interconnected insert columns 3 is inserted into several pre-installed main support columns 1. The truss to be assembled is then hoisted to the end of the installed truss using lifting equipment. The end of the main support column 1 on the truss to be installed is aligned with the insert column 3 and inserted. When the main support column 1 is fitted into the position of the limiting rod 5, the inner wall of the main support column 1 squeezes against the limiting rod 5. When the limit rod 5 is pressed, it retracts into the through hole 6. At this time, the elastic element 4 is compressed. When the main bearing tube 1 continues to move until the through hole 6 matches the position of the limit hole 8, the limit rod 5 is pushed by the tension of the elastic element 4 to insert one end of the limit rod 5 into the limit hole 8, thus completing the assembly between the two trusses. When it is necessary to disassemble the two trusses, several limit rods 5 are pressed into the through hole 6 at the same time using tools. When the limit rod 5 is disengaged from the limit hole 8, the two trusses can be separated, thereby improving the assembly and disassembly efficiency between trusses during the construction of a temporary stage.

[0030] As a technical optimization of this utility model, a hollow column 9 is provided inside the opening 7, and an elastic element 4 is located inside the hollow column 9. One end of the limiting rod 5 is fixedly connected to a limiting plate 10 located inside the hollow column 9 and used to limit the position of the limiting rod 5. The limiting plate 10 limits the position of the limiting rod 5 to prevent the limiting rod 5 from sliding out of the through opening 6 by too much length, which would cause the inner side wall of the end of the bearing tube 1 to be unable to squeeze the limiting rod 5.

[0031] As a technical optimization of this utility model, a first threaded step 11 is provided on one side of the hollow column 9. A fixing ring 12 adapted to the limiting plate 10 is threadedly connected to the side of the first threaded step 11. An elastic element 4 is placed inside the hollow column 9. The elastic element 4 is specifically a spring. The limiting rod 5 is inserted into the fixing ring 12. The fixing ring 12 is threadedly connected to the position of the first threaded step 11, which facilitates the assembly of the whole device.

[0032] As a technical optimization of this utility model, the assembly 2 also includes a polygonal snap-fit ​​ring 13. Both sides of the snap-fit ​​ring 13 are fixedly connected to connecting posts 14. The two plug posts 3 have a second threaded step 15 adapted to the connecting post 14 at their opposite ends. The snap-fit ​​ring 13 is used to connect the two plug posts 3. The connecting post 14 is threadedly connected to the second threaded step 15 and snapped into the snap-fit ​​ring 13 by a tool. The plug posts 3 inserted into the main bearing tube 1 can be rotated, which facilitates the insertion of the limiting rod 5 into the through hole 6. At the same time, different plug posts 3 can be replaced according to the needs of the site, which improves the applicability of the overall device.

[0033] As a technical optimization of this utility model, the inner wall of the opening 7 is provided with a plug groove 16 communicating with the outside. A plug strip 17 is inserted into the plug groove 16. A hollow column 9 is fixedly connected to one side of the plug strip 17. There are multiple hollow columns 9, all of which are fixedly connected to one side of the plug strip 17. After the limiting rod 5 and the elastic element 4 are installed, the limiting rod 5 is pressed and the plug strip 17 is inserted into the plug groove 16. The limiting rod 5 moves into the appropriate through opening 6 to realize the assembly of the parts.

[0034] As a technical optimization of this utility model, both ends of the inner sidewalls of the main bearing tube 1 and the end of the limiting rod 5 are provided with matching compression angles 18, and the end of the plug-in post 3 is provided with a guide angle 19. The limiting rod 5 is compressed by the compression angle 18, and the guide angle 19 facilitates the docking of the plug-in post 3 and the main bearing tube 1.
