Now there are not only a lot of LCD displays indoors, outdoor LCD displays are also too many to count. As a good LCD display construction personnel, only installation is far from enough, the main support structure of outdoor LED billboards are usually based on steel materials, in the open air environment, by the temperature, humidity, harmful substances and other factors, it is very easy to be oxidation and cause rust, serious rust can make the steel components to greatly reduce the ability to resist load, therefore, familiar with some repair and reinforcement methods is also One of the homework of construction personnel. The following small to tell you the outdoor LCD display reinforcement of several methods.
LCD display reinforcement method 1, foundation expansion method: by setting up a concrete enclosure or reinforced concrete enclosure, increase the area of the foundation at the bottom of the outdoor LED billboard to change the uneven settlement of the foundation due to the small bottom area of the billboard foundation and insufficient bearing capacity.
LCD display reinforcement method 2, pit-type replacement method: directly under the foundation to be replaced by digging a pit after pouring concrete.
LCD display reinforcement method 3, pile type to replace the method: the use of the lower or both sides of the billboard foundation set up static columns, driven piles, infill piles and other types of piles to carry out the foundation reinforcement method.
LCD display reinforcement method 4, grouting to replace the method: the chemical slurry will be uniformly injected into the foundation, through these slurries to the original loose soil or cracks glued solid, in order to improve the bearing capacity of the foundation, waterproof and impermeable role.
The following two methods are commonly used to correct the deflection of LCD display foundations.
1、Forced fall correction method
In the outdoor LCD advertising screen foundation settlement more than one side to take measures to prevent sinking, and on the other side to take measures to force subsidence. Forced subsidence methods include: loading ingots or stones, building cantilever beams, hollowing out soil to force subsidence, water injection to correct deflection, etc.
2、Topping correction method
In the part where the foundation of the tilted billboard settles, by adjusting the jacking amount of each part of the billboard, make it rotate along a certain point or a certain line for the whole plane, so as to achieve the purpose of restoring the original position.
