However, when the design function is changed, such as building a distributed photovoltaic power station by using a roof, or modifying an old factory building, the door type rigid frame needs to be reinforced. The reinforcement of the steel structure of the portal rigid frame can be divided into passive reinforcement and active reinforcement according to the action principle. The passive reinforcement means that corresponding reinforcing materials are directly added in the weak areas of the components, and conventional reinforcement means comprise modes of increasing the cross section size of the roof truss beams, increasing the number of the roof truss beams and the like, but the reinforcement modes are complex in construction, slow in progress and high in manufacturing cost, and the reinforcement requirements are difficult to meet. Active reinforcement refers to the targeted application of prestress in a member, solves the problem of stress hysteresis in passive reinforcement, fully exerts the performance of a material, and maximizes the utilization of the material performance. The prestressed carbon fiber tensioning device is widely applied to construction engineering at present, for example, a prestressed carbon fiber tensioning device disclosed in China patent document CN207597277U, so that the door-type rigid frame can be reinforced by the prestressed carbon fiber tensioning device. However, most of the current carbon fiber tensioning devices use jacks for tensioning, which makes it necessary to provide a structure for installing the jacks on the existing portal frame. Furthermore, the use of jacks typically provides pre-stressing for heavy-load buildings such as concrete structures, while the amount of load is smaller for portal frames, so that the use of jacks is not required to provide greater pre-stressing.
