LED Canopy Project Engineering Safety Testing Requirements

In recent years, with the development of social economy and the improvement of scientific and technological level, LED canopy has become a familiar word. Showing the beauty of the integration of LED display and architecture, it has gradually become one of the landmarks reflecting the level of economic development in a region. During the period of use and operation of the LED canopy project, the safety of its structure needs to be inspected and identified on a regular basis. Analysis of structural safety and durability. Including the appearance of the canopy, the relevant parameters of the CFST column, the relevant parameters of the pipe truss and the detection and analysis of the damage. Transparent LED display. According to the test data, the safety assessment is given, and reasonable opinions are put forward, which can serve as a good reference for the quality inspection of similar projects.

Usually, LED sky screens are built in prosperous commercial centers and densely populated areas. Therefore, various hidden dangers of engineering quality will pose a major threat to the surrounding buildings and life safety. P1.56 flexible led display. The structure of the LED canopy project should be tested and identified. In this paper, the safety identification and analysis of the structure of an actual LED canopy project is carried out. The identification method and process can play a good reference role for similar structural inspections.

Basic detection

Check the cracks at the connection between the steel column and the ground of the LED canopy project. After inspection: whether there are settlement cracks, deformation and displacement at the connection between the concrete-filled steel tube column and the ground of the canopy project; the superstructure works normally, whether there is obvious inclination, displacement and Cracks caused by settlement, etc.

Component layout and section size inspection

Investigate the layout of the components of the LED canopy project, and use steel tape measure, vernier caliper, ultrasonic thickness gauge, etc. to extract 8 concrete-filled steel tubular columns and 8 pipe truss components from the LED canopy project, and measure the cross-section size. The cross-sectional dimensions of the components meet the design requirements.

Detection of bending sag and verticality of CFST columns

The prismless total station was used to extract 8 steel column members from the LED canopy project for bending sag height detection and verticality detection respectively. The measured bending sag height deviation of CFST column members is 1mm~5mm, and the perpendicularity deviation is 0.9mm~20.6mm, which should be less than the limit in the specification.

Dry paint film thickness detection of pipe truss and steel column members

The TT260 cladding thickness gauge was used to extract 30 pipe truss members from the LED canopy project to test the thickness of the dry paint film of the anti-corrosion coating on the surface of the pipe truss truss members. The thickness of the dry paint film of the anti-corrosion coating on the surface of the component to be measured must meet the following conditions: the outdoor should be 150μm, the indoor should be 125μm, and the allowable deviation is -25μm.

Weld quality inspection

For the LED canopy project, 48 butt welds and related line welds were selected for weld quality inspection. The quality of the weld seam measured meets the requirements of the second level of the weld seam quality grade.

Appearance quality, damage and leakage inspection

Check the appearance quality, damage and leakage of the LED canopy project: corrosion of connectors, wrinkling of steel components, sagging, peeling and rusting, as well as cracks and deformation.

In summary, many factors such as construction quality, welding process, corrosion, deformation, uneven settlement of the foundation, etc., have caused major safety hazards to the structure of the LED canopy project. It is necessary to carry out scientific and effective identification and analysis of the LED canopy project structure. Studio led display. At the same time, in order to ensure the safe and effective operation of the LED canopy project, daily maintenance must be adhered to, supplemented by effective detection methods. Repair problems in a timely manner. Achieve optimal maintenance during the service life of the LED canopy engineering system. 

The unique transparent LED sky screen beautifies the city and creates a new advertising model. The transparent LED display is transparent when it is not lit and used, and it is integrated with the graceful buildings and blue sky and white clouds. Visitors do not feel the presence of the display screen at all. While enjoying shopping, tasting food, and strolling leisurely, you can enjoy the sunshine in the clouds during the day, and watch the magnificent and colorful sky screen when night falls. Make shopping trips and friends dating more romantic and dreamy!
