Trusses are used more and more frequently in modern society. Truss is indispensable in the construction of the stage, and its role can not be ignored. The stability of the stage truss often touches many aspects and analyzes the design of the stage truss. Whether it can be stable and durable, the simple way to talk about it is to look at whether the aluminum alloy truss can achieve the balance of the joint body or the fundamental law of the force system. Let's talk about the truss in the stage!
Considering overall considerations, the large steel truss is 57m long and 15.8m high. Due to the limitation of the length of transport equipment and on-site conditions, it can only be manufactured at the factory in sections, and then transported to the site and assembled again after pre-assembly. The construction of the stage was selected by means of aerial assembly of steel trusses, high-altitude sub-assembly, and different from the air assembly, poor operation conditions of high-altitude scattered construction, and the safety of the truss in the high-altitude docking, construction safety and truss level, verticality and welding quality control It is very difficult.
Aluminum alloy truss should insist on the strength of the stage truss is strong enough, as long as enough strength is ensured to ensure that the trusses do not collapse or deformation, so as to ensure the stability of the stage or other exhibition platform, bridge, roof, etc. built by these trusses. And peace.
Thus it can be seen that the design of the truss is also of a commensurately high demand. Truss A flat or spatial load bearing member consisting of a number of straight bars, usually with a triangular grid. There must be good articulations, superb welding techniques, fair dimensions and suitable raw materials.
Truss under the action of the load, the truss rods are mainly subject to axial pressure or tension, which can be fully applied the strength of the data, when the span is larger than the real girder to save the data, reduce the weight and increase the stiffness, so for the larger span The load-bearing structures (such as roof trusses, supporting trusses, floor truss girders, bridges, crane bridges) and tall structures (such as transmission line towers, radio towers, satellite launch towers).
