Outdoor LED, as a typical representative of the outdoor application of LED advertising screens, is suitable for many fields because of its convenient maintenance, energy saving and power saving, stable and reliable operation. Basically, common LED advertising screens come in many forms, but no matter which one, good color expression is a beautiful scenery in a bustling city.
If you want to use outdoor LED advertising screens well, installation and debugging is essential. For technical construction personnel, knowing the skills of outdoor construction and maintenance of advertising screens will effectively promote business advertising and information dissemination, and it is also necessary for technical construction personnel. Familiar, specifically speaking, there are four steps in the installation of outdoor billboard LED electric advertising screens: field survey, equipment construction, installation, debugging and use.
When building outdoor LED display screens, it is necessary to distinguish between wall advertising screens, hanging advertising screens and rooftop advertising screens. In actual installation, cranes and hoists should be used for lifting in sections according to the distance and height, and at the same time, ensure that the above personnel cooperate with each other. There is a better installation and use process for the LED advertising screens for high-altitude operations. During the construction process, safety and refined operation are the first requirements.
Of course, as an excellent LED advertising screen construction personnel, it is not enough to only install. The main support structure of outdoor LED advertising screens is usually made of steel materials. In the open environment, it is affected by temperature, humidity, and harmful substances. It is easy to be oxidized and cause corrosion due to the influence of other factors. Severe corrosion can greatly reduce the load-resistance ability of steel components. Therefore, it is also one of the homework for construction personnel to be familiar with some maintenance and reinforcement methods.
Maintenance and reinforcement methods of outdoor LED advertising screens:
1. Foundation expansion method: increase the area of the bottom foundation of outdoor LED billboards by setting concrete enclosures or reinforced concrete enclosures, and change the uneven settlement of the foundation caused by the small base area of the billboards and insufficient bearing capacity.
2. Pit-type underpinning method: concrete is poured directly after digging a pit under the underpinning foundation.
3. Pile underpinning method: The method of using various piles such as static pressure columns, driven piles, and cast-in-place piles to be used for foundation reinforcement at the lower part or on both sides of the billboard foundation.
4. Grouting underpinning method: Inject chemical grout evenly into the foundation, and LED display manufacturers use these grouts to cement and solidify the original loose soil or cracks to improve the bearing capacity of the foundation, waterproof and impermeable.
Correction is to use artificial means to reversely tilt the inclined foundation to achieve the purpose of correcting the tilt of the outdoor LED advertising screen.
