Pre-stress reinforcement method: th

Pre-stress reinforcement method: this method can reduce the stress level of the reinforced components, not only can make the reinforcement effect better, but also can greatly improve the carrying capacity of the whole structure, but the reinforcement has a certain impact on the appearance of the original structure; However, this method cannot be used in environments where temperatures above 600 degrees Celsius cannot be used without protection, nor can it be used for structures where concrete shrinks and becomes larger.Increased support reinforcement method: This method is simple and reliable, but liable to damage the original appearance and use of buildings, and may reduce the use of space; The technology used in supporting the reinforcement and transformation of concrete structures generally includes the technology of tofitting technology, connecting beam, tearing column, supporting beam and beam replacement column, and is a comprehensive technology consisting of the related structure reinforcement, the upper structure lift and reset and the removal of waste components, and suitable for the reinforcement and transformation of existing buildings, compared with traditional practices. This reinforcement method has the advantages of short construction time, low cost and low impact on life and production, but it has high technical requirements and needs to be completed by skilled workers in order to ensure the safety of its construction.Hamstring technology: This is a simpler and more effective connection and anchoring technology for concrete structures; This method of reinforcement has been widely used in the reinforcement and transformation of existing buildings, such as: the construction of buried steel or rebar deviation from the design position of the remedy, components to increase cross-section reinforcement of the ribs, the upper structure of the extension, the rise to beams, columns, the housing layering columns and high-rise buildings to add shear wall planting and other phenomena.Crack repair technology: according to the cause, character and size of concrete cracks, different sealing methods are used to repair, so that the structure due to cracking and reduce the use of function and durability to restore a special technology;Carbonized concrete repair technology: refers to the technology that curbs the corrosion of rebar caused by carbonization by restoring the alkalinization of concrete or increasing its impedance.Concrete surface treatment technology: refers to the use of chemical methods, mechanical methods, sandblasting methods, vacuum vacuuming methods, water-shooting methods, such as the removal of concrete surface stains, oil marks, residues and other attachments of the specialized technology.Concrete surface sealing technology: refers to the use of flexible sealant filling, polymer grout, coating and other methods of concrete waterproofing, moisture and cracking treatment technology. Other technologies: such as structure, component shift technology, adjusting the structure self-vibration frequency technology.
