Precautions for fixing trusses Trusses are mainly used to build a stage, and the quality of trusses largely determines the overall effect of the stage. Generally, truss is used to build the conference stage background, and it is usually built in the space 70- 100Cm away from the stage. Before building the truss, you should look at the site and measure the specific size of the hotel stage. Under normal circumstances, it is a gap 50Cm from the ceiling. In this way, the best visual effect is achieved. Before building the stage, it is necessary to determine the environment for building the truss: it mainly includes the length of the stage, and the truss length and the stage length should be as equal as possible. The height of the background plate is very important. The decoration style of each hotel is different, and the height of the ceiling from the floor is also different. As long as the picture of the background board can be accurately designed after field measurement. Confirm the dimensions of the truss. If it is too high to fit the truss, it is a waste of time. Usually look at how other masters build it, and you will be able to master the skills in a few times. If there are many people, fix the cable ties in a corner and then pull them into a row. If there is a person, tie the belt from one side first, and don't tie it too tightly, and then tie it tightly when the line is almost fixed.
