The support structure of LED display screen is divided into three types: floor type, wall type and roof type. The stress and strain characteristics of each type of support structure system are different. Through the finite element analysis and comparison of the three supporting structure systems, the optimization scheme of the corresponding supporting structure is obtained. The results show that the cantilever column of the floor-standing support system should adopt a circular cross-section, the wall-mounted horizontal support system should adopt a composite truss, and the roof-type support structure should adopt a space truss system. Optimize the design of the key nodes of the supporting structure, and optimize the stress state of the nodes by setting up shear keys or cross-shaped stiffeners to improve the safety performance of the supporting structure.
With the development of multimedia technology, LED electronic display screens are widely used in commercial display and produce good advertising effects. The well-designed display screen support structure can also become a beautiful landscape in urban buildings. In combination with the viewing distance requirements of the display screen and the characteristics of the investment area, the structure type design is usually carried out according to the construction site and building requirements. The LED display is usually set up in a stand-alone form or an auxiliary building. According to the support structure of different display screen forms, the force characteristics of the support structure should be accurately analyzed and the corresponding structure form should be selected. This article will classify and summarize the support structure of the LED electronic display screen, and propose the applicable scope of various support structure solutions, design difficulties and corresponding Optimize design schemes and structural measures.
Display support structure type
1.1 Floor-standing support structure
Floor-standing LED electronic displays are mostly set up in city squares or important traffic intersections. Analyzing the force characteristics of the supporting structure of the floor-to-ceiling display screen shows that the supporting structure should adopt a spatial steel truss structure. On the foundation, 4 steel columns are combined to form a space lattice column. The upper part of the screen body adopts a multi-layer horizontal space truss structure, which can not only meet the structural force requirements, but also meet the setting of the maintenance channel.
1.2 Wall-mounted support structure
The urban construction density is relatively high, and only a few areas can meet the construction conditions of floor-standing display screens. The LED electronic display screen has the advantages of playing dynamic picture advertisements, and a large number of LED display screens need to be built in the prosperous urban commercial area. The solution to this contradiction is to build a display screen attached to the existing buildings.
According to the building's construction conditions, renovation conditions and building height, the LED display supporting structure attached to the building is usually divided into a wall-mounted display supporting structure and a roof-mounted display supporting structure.
The supporting structure of the wall-mounted display screen is mostly fixed to the side of the main structure with a single-layer steel structure, and an inspection channel is set inside.
1.3 Roof support structure
In actual use, the wall-mounted LED electronic display screen occupies a large building facade and will affect the lighting of the building. Therefore, the wall-mounted electronic display screen is only suitable for large commercial buildings such as shopping malls. The LED electronic display screens installed in office buildings and civil residential buildings with moderate building height can only be designed on the top of the building. At this time, the display support structure system should be classified as the roof display support structure.
