The importance of the display steel structure and the installation principle
With the development of LED display applications to expand, LED display steel structure and structure of the form is also more and more complex, which gives LED display steel structure design and construction has brought new challenges. LED profiled screen design design innovation and development, it is required to install LED steel structure technology should also be improved.
However, due to the overall market reasons, LED display steel installation accident and illegal frequency has 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 in addition to strengthening the construction site management, but also in the construction organization design, program, technical measures and other aspects of research summary; vigorously promote new technologies, Characteristics, the choice of advanced, reliable, economical construction program.
LED display steel structure lifting the basic principles of the program:
1, policy - to draw on the basis of norms as a criterion, strict implementation of the relevant national safety regulations.
2, reliability - adhere to the safety first, to ensure the feasibility of the implementation of the program to increase its reliability. Whichever method, first of all to consider whether the program has a successful precedent and supporting equipment, or must be a program demonstration. According to the structural characteristics of the construction check to prove that the method in the construction phase of the stability of the structure, rod stress and deformation, etc. meet the requirements. The use of mechanical equipment can meet the installation requirements. Construction site conditions are met, such as civil construction environment and the surrounding structures are restricted to the implementation of the program.
3, advanced - With the development of science and technology, structural installation in the field of new technology, new technologies, new equipment after another. Such as the large tonnage of the crane come out, the computer synchronization control overall lifting and sliding technology for the installation of the structure to add a new chapter. Especially large-scale steel structure project, in the field conditions and structure to allow, should vigorously promote the application of new technologies, new technology; minimize the amount of high-altitude operations, and continuously improve the efficiency of steel installation.
4, economy - a good installation program should be simple, appropriate measures, high efficiency, low construction costs, wide range of applications, can withstand the review and test. Therefore, we must adhere to the principle of program comparison, technical and economic analysis, select the short duration, low cost of the program.
LED display steel structure steel structure is usually made of lightweight steel (such as stainless steel tube, small cross-section I-beam, hot-rolled H-beam, etc.) made of structural skeleton. LED display module is fixed in the front of the skeleton, showing the gap between the module and the skeleton of the need to use aluminum, aluminum-plastic panels and other wrapping material to cover, wrapping material material, color, gloss needs to coordinate with the surrounding environment. If the height of the display screen over a certain range (about 2m or so), the skeleton should also be added to the corresponding maintenance platform, ladder and other permanent components for the latter part of the maintenance and repair. When the display area is large, the display module of the distribution of heat generated after the module will form a higher temperature, so also equipped with the necessary cooling equipment. At the same time the need for structural surroundings need to use insulation materials for coating (such as rock wool sandwich panels). As the LED display are generally erected in the old building, it must pay attention to the LED display frame with the original building waterproofing. Special reminder is: the original design of the original building did not consider the LED display load, so the design of LED display steel structure must provide the reaction force by the original design of the architect after the calculation of approved construction.
