Outdoor LED advertising screen how to repair and reinforce?

Outdoor LED billboards are typical representatives of outdoor applications for LED displays. They are suitable for use in many fields because of their easy maintenance, energy saving, and stable and reliable operation. Basically, the common LED display has many forms, but no matter what kind, good color expression is a beautiful scenery in the bustling city.

In order to use outdoor billboards well, installation and debugging are indispensable. For technical construction personnel, knowing how to build and maintain advertising screens outdoors will effectively promote the advertisements and information dissemination of businesses, and it is also necessary for technical construction personnel to become familiar with them. In particular, the outdoor billboard LED electronic display installation has four links: field survey, equipment construction, installation, commissioning.

When constructing outdoor LED billboards, it is necessary to distinguish between wall advertising screens, hanging advertising screens, and roof-top advertising screens. In the actual installation, all cranes and hoists should be used to lift the parts according to the distance. At the same time, ensure that the above personnel cooperate with each other. For the LED advertising screens for high-altitude operations, there is a better installation process. During construction, safety and refinement are the first requirements.

Of course, as an excellent LED display construction personnel, it will not be enough to install only. The main support structure of outdoor LED billboards is usually based on steel materials. In the open air environment, it is subject to temperature, humidity and harmful substances. The influence of such factors, can easily be oxidized and cause corrosion. Severe corrosion can greatly reduce the ability of steel components to resist load. Therefore, familiar with some methods of maintenance and reinforcement is also one of the construction workers' homework. Here are some ways we can share outdoor LED billboard maintenance and reinforcement:

1. Based on the expansion method: by setting up concrete surrounds or reinforced concrete enclosures, increase the area of ​​the bottom base of outdoor LED billboards, and change the uneven foundation settlement caused by the small base area of ​​the billboards and insufficient bearing capacity.

2. Pit-type underpinning method: Concrete is poured directly after digging pits on the basis of underpinning.

3. Pile underpinning method: The method of basic reinforcement is adopted for installing various types of piles such as static pressure columns, driven piles and cast-in-place piles on the bottom or both sides of the billboard basis.

4. Grouting underpinning method: The chemical slurry is evenly injected into the foundation, through which the original loose soil or crack cementation is solidified, so as to improve the bearing capacity of the foundation and the effect of waterproof and impervious.

Deviation correction is the use of human means to reverse tilt the tilted foundation in order to achieve the purpose of correcting the tilt of outdoor LED billboards. There are two methods for commonly used outdoor billboard ground correction:

1. Forced fall correction method: Take measures to prevent sinking on the side of the base of outdoor LED billboards, and take forced landing measures on the other side. Forced landing methods include: loading of steel ingots or stones, construction of cantilever beams, forced drooping of earth and water, correction of flooding, etc.

2. Lifting and correcting method: in the site where the tilted billboards have a large settlement, adjust the billboards
