In recent years, with the development of social economy and the improvement of technological level, LED sky screen has become a familiar vocabulary, which shows the beauty of the integration of LED display and architecture, and has gradually become one of the landmarks reflecting the level of economic development of a region. During the use and operation of the LED sky screen project, the safety of its structure needs to be inspected and identified on a regular basis. Analyze structural safety and durability, including detection and analysis of the appearance of the sky curtain, the relevant parameters of the concrete-filled steel tube column, the relevant parameters of the tube truss, and the damage; give a safety assessment based on the test data, and put forward reasonable opinions. Similar engineering quality testing plays a good reference role. Usually, LED sky screens are built in the bustling commercial center area and crowded areas. Therefore, various hidden engineering quality hazards will pose a major threat to the surrounding buildings and life safety. The structure of the LED sky screen engineering should be tested and identified. This paper conducts a safety appraisal analysis on the structure of an actual LED sky screen project. The appraisal method and process can be a good reference for similar structural inspections. 1. The foundation inspection checks the cracks at the connection between the steel column and the ground of the LED sky screen project. After inspection: whether there are settlement cracks, deformations and displacements at the connection between the steel tube concrete column and the ground of the sky screen project; whether the upper structure is working properly and whether there are any settlement cracks, deformation and displacement. Obvious tilt, displacement, and cracks caused by settlement. 2. Component layout and cross-sectional size inspection Investigate the layout of LED sky screen engineering components, and use steel tape, vernier calipers, ultrasonic thickness gauges, etc. to extract 8 concrete-filled steel tube columns and 8 tube truss components for LED sky screen engineering , Carry out cross-sectional size measurement, after testing, the measured component cross-sectional size meets the design requirements. 3. Detection of bending vector height and verticality of concrete-filled steel tube columns Using a prism-free total station to extract 8 steel column components from the LED sky screen project, and perform bending vector height detection and verticality detection on them respectively, and the deviation of the measured bending vector height of the concrete-filled steel tube column components It is 1mm~5mm, and the deviation of verticality is 0.9mm~20.6mm, which are all smaller than the limit value of 'Code for Acceptance of Construction Quality of Steel Structure Engineering' (GB50205-2001). 4. Tube truss and steel column rods coating dry paint film thickness detection The TT260 type coating thickness gauge is used to extract 30 tube truss rods from the LED sky curtain project, and the dry paint film thickness of the anticorrosive coating on the surface of the tube truss rods In the test, the thickness of the dry paint film of the anticorrosive coating on the surface of the measured component must meet the requirements of the 'Code for Acceptance of Construction Quality of Steel Structure Engineering' (GB50205-2001): outdoor should be 150μm, indoor should be 125μm, and the allowable deviation is -25μm. 5. Weld quality inspection uses a digital display ultrasonic flaw detector to extract 48 butt welds and related line welds from the LED sky screen project for weld quality inspection, and the measured weld quality meets the requirements of weld quality level II. . 6. Appearance quality, damage and leakage inspection Check the appearance quality, damage and leakage of the LED sky screen project: connector rust, steel component wrinkle, drop, peeling and return rust, as well as cracks and deformation. In summary, many factors such as construction quality, welding process, corrosion, deformation, uneven foundation settlement, etc., have caused major safety hazards to the structure of the LED canopy project, which requires scientific and effective identification and analysis of the LED canopy project structure; 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, and timely repairs to the problems that occur, to achieve the optimal maintenance during the life of the LED canopy project system. The unique transparent LED sky screen beautifies the city and creates a brand-new advertising model. The transparent led display is transparent when used without lighting, and is integrated with the graceful building and the blue sky and white clouds. Visitors cannot feel the presence of the display at all. While enjoying shopping, tasting food, and leisurely strolling, you can enjoy the sunshine in the clouds during the day, and the magnificent and colorful sky screens at night will make your shopping trip, gathering and dating more romantic and dreamy!
