Steel structure reinforcement has a lot of kinds of methods, for example welding reinforcement law, stick steel reinforcement law and bolt reinforcement law, still have a kind is prestressed reinforcement. Today we talk about the construction steps of prestressed steel structure reinforcement.

Prestressed reinforcement law: prestressed reinforcement law has two kinds of programs, the first is directly paste, the second is the vertical beam as a prestressed cable adjustment stress. The latter is usually suitable for the whole building structure of the overall processing, and the former is the two ends of the anchorage and prestressed, and then through the cross paste component surface, this method is mainly used in the construction of the surface of the rod, the component and its local operation.

Reinforcement material selection: steel structure reinforcement engineering to choose higher strength of the material, reinforcement engineering can use based carbon fiber, its strength can reach thousands of mpa.

Steel structure reinforcement design: steel structure reinforcement needs to do reinforcement according to the structural part of the force characteristics, and the path of force transmission, etc., to determine the amount of cloth and laid direction. The fiber direction should be consistent with the reinforced component and the component with the largest stress. If the stress in the reinforcement area is complex, the orientation and layering of the fiber must be consistent with the direction of the control principal stress.

Embedded prestressed tensioning: the traditional prestressed reinforcement is often tensioned after anchorage, which requires relatively complex tensioning machines and tools, as well as corresponding counter-force devices. And steel structure is special, it needs a simple way of prestressing, embedded prestressing tensioning technology, its characteristics is first anchorage after tension, do not need complex tensioning machine.
