As the strength of steel than other common engineering materials, so the outdoor LED billboards of the main support structure are usually based on steel materials. The steel material in the open air environment, by the temperature, humidity, harmful substances and other factors, easily oxidized and cause corrosion, serious corrosion can make steel components anti-load capacity greatly reduced, so we need to Outdoor LED billboard repair and reinforcement.
For everyone to introduce a simple outdoor LED billboard repair 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. Commonly used outdoor billboard foundation correction methods are the following:
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.
