LED display support structure is divided into floor type, wall mounted and roof type 3, each type of support structure system stress and strain characteristics are different. Through the finite element analysis and comparison of three kinds of support structure systems, the optimization scheme of the corresponding support structure is obtained.

Floor-to-ceiling LED electronic displays are mostly located in city squares or important traffic intersections. The analysis of the mechanical characteristics of the support structure of the floor display shows that the support structure should adopt the space steel truss structure. On the basis, 4 steel columns are arranged to form a spatial lattice column. The upper part of the screen body adopts multi-layer horizontal space truss structure, which can not only meet the structural force requirements, but also meet the maintenance channel setting.

The effective size of the screen is 13.4m×8.6m, which is a typical floor support structure, and the grid column is used to form the display support structure system. The four main limbs of the steel lattice column are 300mm×300mm×10mm, the horizontal transverse material is 200mm×100mm×6mm, and the diagonal bar is 100mm×100mm×6mm, and the maintenance passage is provided in combination with the internal space of the lattice column. The back component of the screen body adopts steel truss structure, the upper chord rod, the lower chord rod and the belly rod all adopt the mouth 100mm×100mm ×6mm, and the upper part is laid with 6mm thick steel plate to meet the requirements of the overhaul passage. The foundation is independent concrete foundation.

Wall-mounted support structure The density of urban construction is large, and only a few areas can meet the construction conditions of the floor display. The LED electronic display has the advantages of playing dynamic screen advertising, urban commercial areas need to build a large number of LED displays, the solution to the contradiction is to build a display attached to the existing building. According to the construction conditions of the building, the reconstruction conditions and the height of the building, the LED display support structure attached to the building is usually divided into wall-mounted display support structure and roof display support structure.

The support structure of the wall-mounted display is mostly fixed on the 1 bay surface of the main structure with a single-layer steel structure, and the maintenance channel is provided inside. China Telecom Wenzhou Branch South Station LED large screen engineering display 24.0m×13.4m, belongs to a typical wall-mounted display support structure, the use of square steel pipe 160mm× 160mm×6mm to form a node system, channel steel 14a laid 6mm thick embossed-steel plate to form a maintenance channel. Each node is anchored to the side of the main structure frame column by six M16 anchors.

In actual use, the wall-mounted LED electronic display occupies a larger building facade, which will affect the lighting of the building, so the wall-mounted electronic display is only suitable for large commercial buildings such as shopping malls. The LED electronic display set up 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.

The display support structure is set on the top of the building, making full use of the original main structure shear wall set steel lattice system, the beam and column are used lattice members, forming a space truss system with good stress state. The effective size of the display screen body is 17.5m×8.0m, the four main limbs of the steel lattice column adopt the mouth 100mm×100mm×5mm, the horizontal transverse material adopts the mouth 100mm×100mm×5mm, and the diagonal bar adopts the mouth 60mm×60mm×5mm. The horizontal transverse and vertical beams respectively form the truss system to resist lateral wind load and seismic load. The nodes are anchored to the main structure with 10 M12 bolts
