Outdoor large - screen construction and maintenance methods
Outdoor LED billboards as a typical LED display outdoor applications, because of its easy maintenance, energy saving, stable and reliable operation in many fields. Basically, the common LED display has many forms, but no matter what kind of good color expressive force is a beautiful city of a beautiful landscape.
In order to outdoor billboards with good, installation and debugging is essential, for technical construction personnel, understand how to build outdoor, maintenance of advertising screen technology will effectively promote the commercial advertising, information dissemination, but also technical staff must be familiar with , Specifically, outdoor billboards LED electronic display installed in four areas: field survey, equipment structures, installation, commissioning use.
For some outdoor LED billboards to build, to distinguish between the wall advertising screen, hanging advertising screen and the top of the advertising screen. The actual installation, should be based on the distance, with the crane and hoist for sub-hoisting, while ensuring that the above staff with each other, for high-altitude operation of the LED advertising screen, there is a better installation process. During the construction process, safety and refinement operation is the first requirement.
Of course, as a good LED display construction workers, will only be installed is not enough, outdoor LED billboards of the main support structure are usually based on steel materials, in the open air environment, by the temperature, humidity, harmful substances And other factors, can easily be oxidized and cause corrosion, serious corrosion can make steel components anti-load capacity greatly reduced, therefore, familiar with some maintenance and reinforcement method is one of the construction staff homework. Here we have to share the outdoor LED billboards maintenance and reinforcement methods:
1. Basic expansion law: through the provision of concrete enclosures or reinforced concrete enclosure, to increase the outdoor LED billboards under the base of the area, change the billboard base area is too small, the bearing capacity of the foundation of the uneven settlement.
2. Pit-type care method: directly under the basis of the underpinning pouring concrete pouring.
3. Pile care method: the use of billboards in the lower or both sides of the static pressure column, into the pile, pouring pile and other types of piles to carry out the basic reinforcement method.
4. Grouting entrainment method: the chemical slurry evenly into the foundation, through the slurry to the original loose soil or crack gel curing, in order to improve the bearing capacity of the foundation, the role of waterproof impermeability.
Correction is the use of artificial means to tilt the foundation of the reverse tilt operation to achieve the purpose of correcting the tilt of outdoor LED billboards. Common outdoor billboards ground correction methods are the following two:
1. Landing correction method: in the outdoor LED billboard base settlement more than one side to take measures to prevent sinking, while the other side to take the measures to take down. The method of landing includes: loading steel ingots or stones, constructing cantilever beams, digging soils, and water leveling.
2. Lifting correction method: in the tilt billboard base settlement of the larger parts, by adjusting the billboards of the various parts of the amount of lifting, so that along a certain point or a straight line for the whole plane rotation in order to achieve the purpose of restoring in situ.
