Abstract
The utility model provides a carbon fiber reinforced framework beam, comprising a framework beam, wherein carbon fiber strips are adhered to the bottom part along the direction of the framework beam; a plurality of U-shaped carbon fiber hoops which are vertical to the carbon fiber strips are adhered to the carbon fiber strips; and a piece of carbon fiber cloth is respectively adhered to each of two sides of each U-shaped carbon fiber hoop. The carbon fiber reinforced framework beam provided by the utility model has the characteristics of convenience for construction, wide application range, no changes of a structural shape and weight, and the like, so that the carbon fiber reinforced framework beam has great research and popularization values and market potential.
Description
Technical field
The utility model belongs to technical field of building construction, relates in particular to a kind of reinforcing technique.
Background technology
The carbon fiber reinforced concrete structure is a kind of reinforcing technique emerging over past ten years, reinforces main material carbon fiber and has high-tensile, high elastic modulus, light weight, thin thickness, corrosion resistance and good, characteristics such as easy to use.CFRP strengthening techniques is to utilize resinous material that carbon fiber is pasted on structure or component surface; Make carbon fiber and concrete form a plyability integral body; Collaborative work through itself and structure or member; Improve bending resistance, the shear resistant capacity of structural element, thereby reach the structural element reinforcing and improve the purpose of stress performance.
The utility model content
The purpose of the utility model provides a kind of carbon fiber reinforcement Vierendeel girder.
Adopt following technical scheme in order to solve the problems of the technologies described above: a kind of carbon fiber reinforcement Vierendeel girder; Comprise Vierendeel girder; Direction along Vierendeel girder is pasted with carbon-fibre strips in the bottom; On carbon-fibre strips, be pasted with several perpendicular U type carbon fiber hoops, be pasted with carbon cloth respectively in U type carbon fiber hoop both sides.
Described carbon-fibre strips and Vierendeel girder bottom are with wide.
Wide 50 ~ the 200mm of described U type carbon fiber hoop, the spacing between each U type carbon fiber hoop is 200 ~ 500mm.
What paste use is epoxy resin.
The utlity model has construction convenient, of many uses, do not change characteristics such as planform and weight, have very big research promotion to be worth and market potential.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
As shown in Figure 1; A kind of carbon fiber reinforcement Vierendeel girder; Comprise Vierendeel girder 1, along the direction of Vierendeel girder be pasted with in the bottom with the Vierendeel girder bottom with wide carbon-fibre strips 2, on carbon-fibre strips 2, be pasted with several perpendicular U type carbon fiber hoops 3; U type carbon fiber hoop 3 wide 100mm, the spacing between each U type carbon fiber hoop 3 is 200mm; Be pasted with carbon cloth 4 respectively in U type carbon fiber hoop 3 both sides.
Cut out carbon-fibre strips, U type carbon fiber hoop, carbon cloth by the reinforcing design size; The carbon fiber of general designation below carbon-fibre strips, U type carbon fiber hoop, the carbon cloth; Carbon fiber direction after should noting cutting out is consistent with the direction of pasting the position, forbids obliquely to cut the carbon fibre, and prevents the wire drawing phenomenon.Carbon fiber after the cutting should be rolled into web-like, prevents fold, bending.
Paste reply concrete surface wiping once more before the carbon fiber, confirm that stickup face does not have dust after, with epoxy resin-impregnated be applied in equably the position that will paste.During the brushing resin, must accomplish the requirement of " steady, accurate, even ", that is: steady, brush firmly appropriateness, do not flow as far as possible and do not weigh down; Accurate, accurately to brush pasting the position, brush is full and do not go out control line; Even, thin and thick uniformity in the brushing scope.
When carbon fiber is pasted, want " steady, accurate, even " equally, require to accomplish firmly appropriateness, make that carbon fiber does not wrinkle, do not roll over, extension is smoothly smooth and easy.During the roll extrusion carbon fiber, must from one end to the other side repeatedly carry out roll extrusion, squeeze remove bubble with the cylinder of special use, should not be at a position repeatedly roll extrusion rub, should let impregnating resin fully permeate carbon fiber in the roll extrusion, accomplish to soak into full.When carbon fiber need overlap, lap length must be greater than 100mm, and guaranteed that the resin of overlapping part soaks into quality.
