Embodiment 1

[0032] Such as figure 1 As shown, this embodiment relates to a carbon fiber strip reinforced structural member, which is characterized in that: it includes a structural member and a carbon fiber strip 1 coated on the outer surface of the structural member, and the carbon fiber strip 1 is spirally wound and tightly pressed on the on the outer surface of the structural member. The structural members are beams or columns.

[0033] In the present invention, the self-locking fixing structure of the carbon fiber strip 1 is used to coat the structural member to achieve the purpose of strengthening the structural member, without using flammable and combustible adhesives as the link, so that the carbon fiber strip 1 is damaged under high temperature. Belt 1 can still have a good restraint effect on structural parts, which solves the problem that the adhesive and fiber matrix material bonding carbon fiber and structural parts fail under high temperature such as fire, which may easily l...

Embodiment 2

[0050] This embodiment is based on Embodiment 1, such as figure 2 As shown, in the process of thread winding structural parts, when the carbon fiber strip 1 is not long enough, as an improvement to the carbon fiber strip 1, such as figure 2 As shown, after the tail end 32 of the first carbon fiber strip 3 is processed in step 3), the tail end 32 of the first carbon fiber strip 3 is overlapped with the head end 41 of the second carbon fiber strip 4, After the head end of the second carbon fiber strip 4 is tilted, it is overlapped and wound no less than 3 times along the circumferential direction of the structural member, and the tail end 32 of the first carbon fiber strip 3 and the tail end 32 of the second carbon fiber strip 4 The head end 41 is pressed tightly into the second carbon fiber strip 4 . The length of the tail end 32 of the first carbon fiber strip 3 and the head end 41 of the second carbon fiber strip 4 pressed into the second carbon fiber strip 4 is not less t...

Abstract

The invention relates to a carbon fiber strip reinforced structure component. The carbon fiber strip reinforced structure component comprises a structure component and a carbon fiber strip coated on the outer surface of the structure component, wherein the carbon fiber strip is spirally wound and pressed on the outer surface of the structure component. The invention also provides an implementation method of the carbon fiber strip reinforced structure component. The implementation method is characterized by comprising the following steps: (1) winding the head end of the carbon fiber strip; (2) axially and spirally winding and pressing the carbon fiber strip along the structure component; (3) winding the tail end of the carbon fiber strip. The carbon fiber strip is used for coating the structure component, so that the purpose of reinforcing the structure component is achieved; the head end and the tail end of the carbon fiber strip are respectively subjected to press-in winding and tying treatment, so that the purpose of self locking and anchoring is achieved; the carbon fiber strip is not required to be bound by a flammable adhesive, so that the carbon fiber strip still has high restraint effect on the structure component under the high-temperature breakage; the carbon fiber strip has the advantages of high temperature resistance, long service life and environment friendliness.

Description

technical field [0001] The invention belongs to the technical field of construction, in particular to a carbon fiber strip reinforced structural part and a realization method thereof. Background technique [0002] Since the large-scale development of my country's construction industry in the last century with the favorable economy, a large number of houses are close to the design life. May face serious quality and safety problems. The measures of total demolition and reconstruction are not only contrary to the needs of sustainable social development and the concept of conservation and environmental protection, but also not conducive to the needs of my country's modernization drive. [0003] Fiber-reinforced polymer composites (Fibre-Reinforced Polymercomposites, referred to as FRP) are widely used in building structure reinforcement due to their high strength, light weight, good fatigue resistance, strong designability, stable structure size, and high corrosion resistance at...
