With the development of the market economy and the acceleration of the process of industrialization, the number and scale of theater performances are increasing. In order to ensure the safety of the performance, the truss structure can be used in the construction of the performance stage. The truss structure can not only improve the quality of the stage, but also has the characteristics of large span and low cost. Therefore, the editor has organized how the truss structure is carried out in the stage construction. Optimize the design, let's look at it together.
The truss structure is a commonly used beam structure, which has the characteristics of flexible structure layout, strong bending resistance, strong shear resistance, and wide application range. The application of the truss structure in the stage construction can effectively enhance the shear resistance and compression resistance of the stage, which is conducive to improving the quality of the stage. However, some current stage construction companies still have some problems when applying the truss structure, and need to continuously optimize the design of the stage truss structure in order to give full play to the role of the truss structure.
1. Truss structure in stage construction
The layout of the stage truss structure is relatively flexible, both in bending resistance and shear resistance, so it is suitable for buildings with various spans. According to the shape of the truss, the truss structure can be divided into parallel chord truss, folded chord truss and triangular truss. Currently, in the actual performance process, the internal space of the stage is large, and the structure is complicated due to the impact of the temporary venue environment. Due to the requirements of the performance of the light and other conditions, the actual stage construction process of the truss structure has a great impact on the construction technology. The requirements are also relatively high. The stage truss is mainly used to support the stage. After the mechanics test, the stage load-bearing structure meets the actual needs, and the built stage has good stability. It can also be built into a backstage video wall and top floor. Bracket, you can hang background cloth, lights and sound.
2. Optimized design of truss structure in stage construction
2.1 Optimize according to the engineering situation
Engineering construction companies must optimize the design of the truss structure according to the specific conditions of the stage construction project. Only in this way can the truss structure be more in line with the actual needs of stage construction. For example, to make the truss structure fully fit the shape of the roof of the banquet hall, it is necessary to conduct an in-depth analysis of the hoisting environment of the herringbone steel structure roof, and reasonably design the position of the hanging points and the truss structure, so that the truss structure can fully conform to the building need. Before constructing the stage truss structure, engineering construction companies need to perform strict calculations on the span, load-bearing, shape and construction environment required by the project, and then optimize the design of the truss structure.
2.2 Optimize the section size of the stage truss structure
Determining the topology is the basis and prerequisite for optimizing the cross-sectional size of the stage truss structure. When optimizing the cross-sectional size of the stage truss structure, a small amount of size needs to be used to express some changes in the structure, such as the cross-sectional area of each unit of the stage truss, and the position of the nodes. Some changes. Then build a size model based on these specific data, use the corresponding optimization algorithm to calculate the mathematical model, and get an optimized size data, so that the cross-sectional size of the stage truss structure is more in line with actual needs.
2.3 Optimize the shape of the stage truss structure
Optimizing the shape of the stage truss structure can not only make the overall structure more in line with the needs of stage construction, but also improve the performance of the structure and reduce the use of materials, so as to achieve the purpose of reducing timber. Optimizing the shape of the stage truss structure is mainly achieved by adjusting the shape of the inner and outer boundaries. Therefore, it is necessary to clearly distinguish the objects of the stage truss structure shape optimization.
Optimizing the design of the truss structure in the stage construction is of great significance. Only the design of optimizing the truss structure can reduce the cost of the truss structure and make the force of the truss structure more uniform and reasonable. Thereby improving the performance of the truss structure and the quality of stage construction.
