The steel structure installation of LED display screen is a complex comprehensive technology with many contents and a wide range. The following describes the basic principles and applicable conditions of steel structure design in combination with several steel structure projects, and summarizes the feasibility of conventional installation methods and corresponding technical measures
With the development of science and technology, the shape and structural form of steel structure are becoming more and more complex, which brings new challenges to the design and construction of steel structure. For example, the Olympic venues represented by “bird’s nest” and “Water Cube”, as well as the influential steel structure projects such as the National Grand Theatre, the location of the new CCTV station, Guangzhou TV Tower and Famen Temple relic tower, have not only made innovation and development in design, but also made new achievements in steel structure installation technology. Many mature and advanced technical methods have been formed one after another, which has promoted the development of steel structure industry.
Due to market reasons, steel structure installation accidents and violations have occurred, resulting in unnecessary economic losses and social impact. In order to further improve the overall level of steel structure construction and promote the development of the industry, steel structure construction should not only strengthen the construction site management, but also study and summarize the construction organization design, scheme and technical measures. According to the engineering characteristics of vigorously promoting new technologies and processes, an advanced, reliable and economic construction scheme is selected.
Basic principles of steel structure of LED display screen:
1. Policy: Based on drawings and specifications, strictly implement national production safety regulations.
2. Reliability: adhere to safety first, ensure the feasibility of scheme implementation and improve its reliability. No matter which method is adopted, we must first consider whether the scheme has a successful precedent and supporting equipment. Otherwise, the case must be discussed. The construction management is carried out according to the structural characteristics to prove whether the structural stability, member stress and deformation of the method meet the requirements in the construction stage. Can the mechanical equipment used meet the installation requirements? Whether the construction site conditions such as the construction environment and surrounding structures are met, and whether the implementation of the scheme is restricted.
3, advanced: emerge in an endless stream with the development of science and technology, new technologies, new processes and new equipment in the field of structural installation. With the advent of large tonnage cranes, the improvement of the whole computer synchronous control and sliding technology have added a new chapter to the structural installation. Especially for large steel structures, the application of new technologies and processes must be vigorously promoted when the site conditions and structural forms allow. Minimize the amount of work at height and improve the installation efficiency of steel structure.
4. Economy: a good installation scheme should have simple method, appropriate measures, high efficiency, low construction cost, wide application range and stand the examination and test. Therefore, we must adhere to the principle of scheme comparison, conduct technical and economic analysis, and select the scheme with short construction period and low cost. 2、 Applicable conditions of steel structure of LED display screen
Because the architectural shape and structural form are not unified, and the construction site conditions are very different, it can be said that there is no construction method and scheme suitable for any steel structure installation, so each installation method has its own support conditions.
The common installation methods of space truss structures include high-altitude bulk method, strip block installation method, structural sliding method, support sliding method, integral hoisting method, integral lifting method, etc.
