An introduction to the application and construction of stage trusses

Stage truss is a structural system that carries and supports stage equipment, lighting, sound and other equipment in stage construction. Stage truss can provide stable supporting force to ensure the safe operation of stage equipment. The main role of the stage truss is to carry and distribute the weight of various equipment on the stage, so that it can be firmly suspended in the air, while also taking into account the stage scenery, lighting effects and audience vision and other factors.

From the type of stage trusses, there are common steel trusses and aluminum alloy trusses. The steel truss is usually composed of steel pipes, beams and connectors, which has high strength and stability, and is suitable for large-scale performances and long-term construction of the stage. The aluminum alloy truss is made of aluminum alloy material, which has lighter weight and excellent corrosion resistance, and is suitable for the construction of small mobile stage performances. Choosing the right type of truss needs to be determined according to the specific performance needs and site conditions. In addition, the material of the stage truss is also an important factor to consider. Steel trusses are usually made of high-strength steel, which has a high load-bearing capacity and durability, and can be used for a long time and maintain stability. Aluminum alloy truss is made of lightweight aluminum alloy material, in addition to having a light weight, but also has good corrosion resistance and fire resistance, the choice of material needs to be based on the specific requirements of the construction and budget.

The structural design of stage truss mainly includes support mode and connection mode. In terms of support, stage trusses are usually hung and supported. Hanging trusses are suspended on the top of the stage by hoisting, which has the advantage of providing greater space and flexibility, and the stage of this structure is suitable for large stages and complex scenery construction. The braced truss supports the feet on the ground. It can provide more stable support force, suitable for small performances and simple set construction. For the stability and safety of the stage truss, the connection method is also very important. There are two common connection methods: bolt connection and bolt link. Bolt link connects the various components of the truss together through bolts and nuts, which has high stability and load-bearing capacity. The latch link is to fix the various components of the truss together through the latch, which has the advantage of convenient disassembly, and is suitable for occasions that need to be constructed and dismantled frequently. The choice of connection mode needs to consider the convenience of use and the stability of the connection.

When using stage trusses, they must be operated in accordance with the construction specifications and user manuals to ensure the stability and safety of the trusses. In addition, it is necessary to check and maintain the truss regularly to ensure the tightness of the connectors and the integrity of the materials used. In the process of building and dismantling the stage truss, the staff need to wear protective equipment such as hard hats to ensure their own safety. It is also necessary to operate in accordance with relevant laws and safety standards to ensure the safety of the performance venue.
