Problems solved by technology

[0003] The stirrups in the existing prefabricated assembly system are all single stirrups made of handmade steel, and the spiral stirrups are surrounded by hand. Its size is difficult to grasp, and it takes a lot of manpower and time; It is inconvenient, and it will increase the overall weight of the component and increase the cost; and because there are solder joints or openings on each single-turn stirrup, its shrinkage force is uneven
[0004] The purpose of the present invention is to overcome the deficiencies of the prior art of prefabrication and assembly, and provide a processing method for fastening closed stirrups of FRP composite building materials, which can overcome the shortcomings of the existing single-loop stirrups, and can also strengthen the edge components function, break through the limitation of prefabricated assembly system, and realize the popularization and use of prefabricated assembly system in high-rise buildings

Abstract

The invention provides a machining method for fastening sealing hoops made of an FRP composite building material for a prefabrication assembly system. According to the following technical scheme, the machining method for the fastening sealing hoops made of the FRP composite building material for the prefabrication assembly system is characterized by including the steps that the FRP material is compounded through a compounding wire twisting board and a compounding wire twisting groove, the FRP material and iron wires of iron wire coils are formed into inner cores through an FRP rib forming pipe and an FRP rib wire outgoing board, the inner cores are dried through a drying box and cooled through ventilation of an air blower, fastening sealing spiral hoop wires made of the FRP composite building material are formed and twisted around a die core column so as to be formed, and the hoops are used for tying operation according to the reinforcing steel bar sample size on a vertical reinforcing steel bar framework of a wall of the prefabrication assembly system to meet the requirement of a design drawing. The method has the beneficial effects that the process is simple and site machining can be achieved; and FRP composite ribs are low in weight and high in specific strength, the tensile strength is higher than that of reinforcing steel bars, the corrosion resistance and the fatigue resistance are good, the service life of the structure is prolonged, flexibility is good, the hoops can be directly twisted on a site, time and labor are saved compared with the situation that a single hoop is manufactured and transported to the site, and cost is low.

Description

technical field [0001] The invention belongs to the technical field of building construction, and relates to a processing method for fastening closed stirrups of FRP composite building materials in a prefabricated assembly system, and in particular to an FRP composite building material used on a prefabricated assembly type construction industry. A processing method for fastening closed spiral stirrups. Background technique [0002] The 2014 edition of "Technical Regulations for Prefabricated Concrete Structures" has corresponding regulations on prefabricated prefabricated shear wall structural systems (prefabricated assemblies): In seismic design, high-rise assembled integral shear wall structures should not all use short-leg shear walls ; When the seismic fortification intensity is 8 degrees, it is not suitable to adopt the shear wall structure with more short-leg shear walls. When adopting a shear wall structure with many short-leg shear walls, when the joints are located...
