Prestressed reinforcement steel construction process and steps prestressed steel reinforcement program can be divided into two types, one is directly attached to law, will anchor the ends and after prestressing steel, attached by adhesive surface of steel structures; generally applicable relatively flat surface on the rod member, or partial reinforcement for members; the second is to adjust the stress of prestressing cable bundle as steel processing, generally applies to the entire structure of the overall reinforcement. 5.1 Selection: carbon fiber for structural reinforcement of the main choice with PAN-based carbon fiber, the ultimate strength of up to 3500MPa, the elastic modulus of about 2.35 × 109MPa. Using epoxy resin system material. 5.2 Design: According to the mechanical characteristics of the structure to be repaired, the force transmission path and the stress - strain field, to determine the amount of fabric, size and laying direction. Fiber orientation should be consistent with the maximum force trauma member orientation. If the injury site in a complex stress state, the fiber orientation and stacking sequence should be consistent with the control of the main stress direction. 5.3 Embedded prestressed tension technology: steel reinforcement particularity prestressing need a simple way, the traditional way is often the first prestressing tension after anchoring, require relatively sophisticated tensioning equipment, and the corresponding Anti-power plant. At anchor when the prestressing loss is relatively large. Embedded prestressed tension technology, which is characterized by the first post-tensioning anchor to anchor member itself and the previous force, as tensioning device, without the complexity of tensioning equipment. Prestressed tension is applied to the embedded technology can be divided into sub-prestressed, the adhesive layer can produce squeeze effect, improve the reliability of paste. Meanwhile, due to the use after the first anchor tensioning technology, small prestress loss, the method is simple and effective. Improve the use of functional devaluation to promote steel residential high-rise, we must improve the steel residential use function, can not let the steel structure housing the impression is cold. Some steel housing demonstration projects all around the building structure to work on, this is wrong. In fact, the structure is for construction services, building consumer use function is most concerned about. Structure or technology or steel contractor, the last to be implemented in the use of functions, to let people see and feel, lived comfortably. Steel housing should use the function as the core. Around the building, the water, heating, electricity integrated together. Some studies have shown that steel residential construction to 18 layers to 20 layers, steel columns will be more than 50 cm in diameter, fire is difficult. The best way is to wrap the steel columns with fire board, but doing so will increase the cost. For now, the steel structure for construction of high-rise residential and small bay steel structure design, after China's economic strength has been further enhanced to build some of the major pillars of the large bay. Steel is the most suitable standardized housing, both to speed up the construction speed, shorten the construction period, but also to ensure quality. In addition, steel residential split up easily, most recyclable materials. At present, China has issued the relevant technical specifications: cities should be built 12 layers to 15 layers of steel residential, pillars diameter of 0.4 meters, 0.4 meters high beam, the height of 2.9 meters to 3 meters.
