Aluminum truss system is the most important structure of stage construction, for the safety of the stage, the quality of Aluminum truss system is very important to pay attention to, why the stage construction nowadays will choose Aluminum truss?
A complete aluminum truss system is mainly composed of aluminum trusses of different lengths and specifications, base, counter head, inclined support, square sleeve, cross brace, hoist, sling, bumper and other accessories to build the combination.
1.Aluminum truss system's base: it can be divided into iron and aluminum base. It is mainly used for the stabilization of the ground.
2.Aluminum truss system's reverse head: used to build a higher height, can be erected through the reverse head to achieve a higher height role.
3. Diagonal brace of Aluminum truss system: It is used to support the stability of the whole system of Aluminum truss.
4.Aluminum truss system square sleeve: The height of the crossbeam can be easily adjusted by the square sleeve.
5.Aluminum truss system cross brace: at the top of the truss, mainly used for hanging hoist.
6.Aluminum truss system hoist: It can be divided into two kinds: hand-pulled and electric hoist, which is used to lift aluminum trusses.
7.Aluminum truss system sling: the link between hoist and aluminum truss.
8. Aluminum truss system bumper: placed under the square sleeve to share part of the pressure of the square sleeve and the crossbeam.
Aluminum truss system load-bearing calculation can theoretically determine the load-bearing condition of the designed truss, which is an important part of truss design. Generally speaking, the calculation of Aluminum truss system is simplified to static calculation, which is commonly known as the force of Aluminum truss system under static environment. These uncertain forces are calculated by multiplying the equivalent static load with corresponding dynamic coefficients after obtaining the static force results. Dynamic analysis is also required to calculate dynamic loads, such as large span bridges, aircraft wings, etc. The calculation of plane trusses is described below.
The Aluminum truss system that we commonly use is generally artificial as a plane truss and is calculated as an ideal articulated truss, i.e., the load of the truss is considered to be on the truss nodes and in the same plane with all the truss members, and the center of gravity axis of all the truss members is in the same line, and the nodes are considered to be articulated points that can be freely rotated. We calculate the static joist in ideal condition by taking the axial force of the rod as an unknown quantity and using the numerical or graphical solution method in statics to find out the axial force of the rod under known known load. The rod bending stress and axial stress due to the influence of node rigidity are called secondary stresses. The calculation of secondary stresses requires consideration of axial deformation of the rod and can be solved by super-stationary structure method or finite element method. The overall stiffness of truss is ensured by controlling the maximum vertical deflection of truss not to exceed the allowable deflection; the out-of-plane stiffness of plane truss is poor and must be ensured by bracing system. The support system consists of upper chord support, lower chord support, vertical support and truss together to form a spatial stability system.
Aluminum truss system is the most important structural material for stage construction. For the safety of the stage, the quality of Aluminum truss system is very important to pay attention to.
1. Aluminum truss has excellent corrosion resistance and durability
Compared with the traditional stage construction material iron truss, aluminum alloy truss is made of 6061-T6 industrial aluminum, which has excellent anti-corrosion characteristics, and its service life far exceeds that of iron truss, generally under normal use a batch of aluminum alloy truss can be used for about 10 to 20 years.
2. Aluminum alloy truss is good quality and light weight
Aluminum alloy truss is lighter than traditional iron truss by more than half, which lightens the burden of stage builders who rely on physical work, so that the building process and transportation will save most of the cost and labor force.
3. Excellent pressure resistance of aluminum alloy truss
The aluminum alloy truss itself is well made and has very good load-bearing and pressure-resisting capacity, generally the aluminum alloy truss can bear more than 600kg on average. It can fully meet the needs of various performance stage construction, celebration stage construction, etc. for hanging large lighting and sound equipment.
The advantage of Aluminum truss system is that it can be used for some professional mobile outdoor performances, which is very convenient to carry, and can also be used for some indoor exhibition stands, which can play a good supporting effect, and it is also very convenient to install and dismantle, and it can be used for some building effects, which can build the effect you want, and of course, it can also be used for some professional mobile outdoor medium-sized performances, which can bear better effects.
