With the rapid development of multimedia, the application of LED display is becoming more and more extensive, especially in business, it is impossible to leave LED display. Combined with the viewing distance requirements of the display screen and the characteristics of the investment area, the structure type is usually designed according to the construction site and building requirements. For the support structures of different display forms, the corresponding structural forms should be selected by accurately analyzing their stress characteristics. Jinan LED is going to introduce the floor-standing support structure of LED display to you today.
The supporting structure of the floor-mounted electronic display screen bears the load of the upper screen structure through the column connected to the foundation, and can be analyzed and calculated according to the cantilever beam structure. The floor-standing support structure usually adopts a single-column or double-column plus beam structure, and the other types can be combined with the building shape to select an appropriate support structure system. The column design can adopt concrete structure, steel tube structure and lattice steel column, and the beam can choose steel structure type such as lattice beam. The selection of the foundation should be determined according to the geological conditions of the site, and the calculation of compression resistance, pullout resistance, bending resistance and overturn resistance should be carried out. Combined with the stress characteristics of the cantilever structure, the key components of the floor-standing support structure are designed as vertical columns, and a section form that is safe and reasonable meets the process requirements.
Combined with the characteristics of the construction period of the support structure of the display screen, the section of the circular steel column and the lattice steel column is selected for analysis, and the amount of steel under the same stress and strain is studied. The finite element analysis software is used to establish the model. The circular steel column adopts color 1000×15, the four main limbs of the lattice steel column adopt 300 mm×300 mm×10 mm, the horizontal transverse material adopts 200 mm×100 mm×6 mm, and the inclined web bar is 100 m×100 mm×6 mm. According to the force characteristics of the cantilever structure, the load on the upper screen is simplified to the top of the cylinder, and the two types of cylinders are analyzed by finite element according to the simplified model. The analysis results show that, for the floor-standing support structure, the cylindrical section and the lattice section are all good section forms. The outdoor electronic display screen needs to be set up with access passages because the electronic display components need to be repaired. The use of lattice columns can make full use of the lattice space to set up access passages, and will not cause the cross section at the root of the column to appear due to the setting of access holes like circular sections. weak spot. When a circular section needs to be set due to the landscape, local reinforcement should be carried out on the part of the master. When both section types can meet practical and appearance requirements, lattice columns should be preferred.
