No matter how gorgeous the stage effect is, reliable structures are also needed to ensure it. As a stage structure with a large proportion and the highest safety requirements, it is the aluminum alloy light truss hanging above people's heads, which is especially joking. Its quality is directly related to the success of performances or exhibitions, as well as the safety of relevant personnel. It is often heard that some performances or exhibition activities have caused performance accidents, so it is very necessary to have a certain understanding of this product in order to better choose the aluminum alloy lighting truss product that is suitable for oneself
1、 First, distinguish from the material
1.6063 and 6005 colloquial: After a certain period of contact between agricultural aluminum and rainwater and air, the aluminum surface turns black and black. Belongs to relatively low-end materials.
2. 6061 Oral: Why is industrial aluminum called industrial aluminum? It is because it has good corrosion resistance and good weldability. At T6 state, the Vickers hardness is 12 degrees.
3.6082 Oral: Aviation aluminum is a new alloy with a Wechsler hardness of 15-17 degrees in T6 state, similar in composition to 6061, and is an upgraded version of 6061. However, due to its better performance, it is widely used in Europe because its tensile strength is about 10-18% higher than 6061. At the same time, due to the reduced copper composition, it has better corrosion resistance, but does not lose any extrusion performance and anodic oxidation reaction. Copper in 6061 is used as the reinforcing phase, while chromium is used for recrystallization control. The copper content in 6082 decreased, and manganese was used for recrystallization control.
2、 Judging from design process
Firstly, we must recognize that stage structure belongs to a type of architectural aluminum structure.
So one characteristic of designing aluminum structures is to use as little aluminum as possible and use thin-walled structures, which requires aluminum alloys to have excellent corrosion resistance and process performance. Generally speaking, the wall thickness of load-bearing structural components is 1.5-3mm, while there are no strict restrictions on envelope structural components. When designing aluminum structures in buildings, attention should be paid to the characteristics of the elastic modulus of aluminum alloy semi-finished products, to prevent deformation, and to ensure the overall and local stability of structural components. When designing aluminum structures, attention should be paid to the rationality of the building structure.
Elaborate on the design of aluminum alloy lighting trusses
1. It is important to pay attention to controlling the weight of the aluminum alloy lighting truss itself, not necessarily the heavier the better. Especially in some unnecessary structures, thickening the material is a waste of cost, and it can also weaken the load-bearing capacity of the truss itself.
2. It is necessary to avoid the design of damaging the cross-section of the profile on the aluminum alloy lighting truss to ensure the integrity of the welding path.
3. There should be sealing strips at both ends of the main pipe of the aluminum alloy light truss. Although the name is sealing strip, it actually needs to be inserted into the main pipe to avoid damaging the welding between the port and the main pipe. This will enhance the stress strength of the truss itself; Only when using and transporting at the same time can the supervisor of the crosswalk avoid safety hazards and unsightly situations caused by collisions that cause sagging of the mind.
3、 Judging from welding process
The manufacturing characteristics of aluminum structures are: they must be produced in specialized workshops or factories; At every stage of production of parts and structures, attention must be paid to maintaining the material's switch and surface state; Special cross-sectional semi-finished products should be used to reduce structural welding and processing costs, with the aim of enhancing the stability of materials and structures.
Generally speaking, high-quality aluminum alloy trusses are finely welded, with regular welders, and the welding path is in a fish scale stacked state. The dimensions are accurate, and there will be no misalignment of connecting holes or misalignment with accessories after the product is formed.
