Embodiment Construction
[0017] The present invention is further described as follows in conjunction with accompanying drawing and embodiment:
[0018] A method for reinforcing steel pipe concrete compression members, the steps of which are as follows: the first step is to clean the surface of the steel pipe 2 surrounding the outer layer of concrete 3; The fiber fabric 1 made of Plastics or Fiber Reinforced Polymer, referred to as FRP, is wrapped around the steel pipe 2 and connected with the steel tube concrete compression member as a whole; the FRP fiber reinforced composite material is selected from carbon fiber reinforced composite material, namely CFRP, It can also be a glass fiber reinforced composite material, namely GFRP, or an aramid fiber reinforced composite material, namely AFRP, etc.; the fiber fabric 1 is a cloth-like fiber product with continuous fibers arranged in one direction and not impregnated with resin. This continuous fiber is The best solution, the fiber fabric 1 can also be a ...

This invention involves one kind of reinforcement steel pipe concrete compressional member the method, it including subordinate step; First step is cleans up the outer layer steel pipe the surface; Second step is textile fiber fabric Uygur which makes the fibrous material covers with the textile fiber cementing agent around the steel pipe, with the steel pipe concrete compressional member connection is a whole; States the textile fiber to strengthen the compound material mainly to elect from to strengthen the compound material to the carbon fiber, the textile fiber fabric textile fiber for unidirectional or / and are many to the arrangement, not cloth shape textile fiber product which soaks after the resin. This invention is provides the tight band strength for the steel pipe also if works together, enhances the steel pipe concrete compressional member the supporting capacity, enhances the steel pipe the rigidity, prevented the steel pipe one kind of effectiveness which corrodes, economical reinforcement method, this method reinforcement effect good, construction operation simple, the reinforcement time limit for a project is short, affects slightly to the production, greatly reduces the project cost, therefore according to European widespread application prospect.
Description
technical field [0001] The invention relates to a method for reinforcing a steel pipe concrete compression member with a fiber fabric, and belongs to the technical field of structural reinforcement of civil engineering engineering. Background technique [0002] Concrete filled steel tubes can adapt to the needs of modern engineering structures to develop into large spans, towering towers, heavy loads and withstand harsh conditions, and meet the industrial requirements of modern construction technology, so they are more and more widely used. However, under the dual effects of long-term natural environment and service environment, steel pipe concrete will be damaged to varying degrees, such as physical aging, chemical corrosion, etc., which will weaken the function of steel pipes, and suffer from floods, wind disasters, fires, and earthquakes, which will damage structures and components. , These will seriously reduce the safety, applicability and durability of the CFST structu...
