Detailed Product Description: | Construction of a steel footbridge) Machinery and Equipment semiautomatic cutting machine, hand presser bar drill, grinder, angle grinder, 25t wheeled cranes, trucks, trailers, welding, gas welding equipment. 2) The main equipment wedge, pulley, down the chain, jack, arc gouging, rope, snap ring, rope clips, feeler, steel tape and water level, such as foot tower. 3) The production process of raw materials in the factory according to the design requirements for correction, lofting, cutting (cut and gas cutting) steel prices, the parts straight Cleaner, planing, drilling, piling steel semi-finished classification, clean up the oil groove rust, steel splice, welding, ultrasonic testing, flattening, weld inspection, checking geometry. In line with the design and specification will be transported to the site of semi-finished. 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, pasted by an adhesive surface of steel structures; generally applicable to member relatively flat surface of the rod, the component or partial reinforcement; the second is to adjust the prestressing cable bundle as stress, 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. Embedded technologies can be divided into sub-tensioned prestressed prestressing steel installation, you can squeeze effect on the adhesive layer to produce steel contractor, 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.
