Abstract
The invention discloses a carbon fiber preformed reinforcement method of existing net rack components. A carbon fiber preformed reinforcement structure comprises preformed body reinforcement components, a preformed connector reinforcement component, a carbon fiber adhesive coated between the preformed body reinforcement components and the preformed connector reinforcement component, and to-be-reinforced net rack components, wherein the preformed connector reinforcement component is connected to the two preformed body reinforcement components; the preformed body reinforcement components are made into components comprising various steel profiles such as hollow cylindrical steel profiles, hollow square steel profiles, U-shaped steel profiles, right-angle-shaped steel profiles and I-shaped steel profiles and the like of the same shape of the net rack components in advance. The net rack components of the corresponding size are taken out on account of different net rack components and are pasted on the surfaces of profiles via a super-strong adhesive; components made by the preformed connector reinforcement component in advance are of the same shape of the net rack components and comprise conical heads, circular heads, two-way pipes, three-way pipes, triangular heads and T-shaped heads and the like with various shapes.
Description
Technical field
The present invention relates to a kind of ruggedized construction of steel construction, refer specifically to a kind of carbon fibre of existing rack component
Dimension preforming ruggedized construction.
Background technology
On the building spy such as large-scale gymnasium, large-scale library and Longspan Bridge, people are frequently used rack steel construction,
These rack steel constructions change its original carrying amount in the case of, will flexural deformation, lead to building inclination even
Collapse, and the rack steel construction re-replacing more high-mechanic amount be equal to be rebuild building, can cause very big manpower and
The loss of material resources.If in the appearance additional layer steel structure member again of original rack steel structure member, building will be increased special
Weight, increase the gravity load of the special beam and column of building.
Content of the invention
In order to solve problem present in above technology, the invention provides a kind of carbon fiber preforming reinforcement means, can
To be reinforced for each rack steel structure member.
The present invention, according to the shape of the different component of grid structure and connection angle, prefabricated carbon fiber is become corresponding and reinforces
Preformed member, in wrong vertical complicated grid structure, can easily reinforce to each component.
The present invention includes preforming main body girth member and preforming union joint girth member to be coated in preforming main body girth member
Carbon fiber rubber and preforming union joint girth member between and treat reinforcing network frame member, described preforming union joint girth member connects
Between two preforming main body girth members.
The assembly with rack component same shape made in advance by described preforming main body girth member, including hollow cylindrical,
Hollow square, flute profile, square, the various shaped steel such as I-shaped, for different rack components, take out to should size net
Frame member, is fitted in the surface of section bar by HHT higher high tensile glue.
The assembly with rack component same shape that described preforming union joint girth member is made in advance, including conical head,
Rounded nose, bipass are individual, tee pipe fitting, and trigonocephaly and t prefix etc. are variously-shaped.
Institute's carbon fiber rubber 3 is the fluoride seccotine of high temperature high voltage resistant, acid-alkali-corrosive-resisting and anti-light oxygen aging.
First each of the rack component outer surface treating reinforcing network frame member is removed dust, carbon fiber rubber is coated in be added
The outer surface of fixed network frame member and inner surface, wrap up in preforming main body girth member and are attached to the surfaces externally and internally treating reinforcing network frame member
On, then preforming union joint girth member is wrapped up in respectively the conical head at each two ends treating reinforcing network frame member being attached to rack
Outer surface.
The profitable effect of the present invention is: 1, take full advantage of superpower tension stress and the machinability of carbon fiber, with
Shaped steel close adhesion, in one, substantially increases tension, shearing resistance and the bend resistance performance of shaped steel；2nd, there is the negative of same iso-stress
Carry the lower thickness that can reduce shaped steel, mitigate the weight of whole building thing, save steel.
Brief description
The present invention is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is present invention rack figure to be reinforced.
Fig. 2 is the single profile treating reinforcing network frame member of the present invention.
Fig. 3 is the conical head carbon fiber preforming girth member schematic diagram that the present invention treats reinforcing network frame member.
Fig. 4 is the dominant carbon fiber preform girth member schematic diagram that the present invention treats reinforcing network frame member.
Specific embodiment
As shown in figure 1, the present invention is a kind of carbon fiber preforming ruggedized construction of existing rack component.
As shown in Fig. 2 in order to solve problem present in above technology, the invention provides a kind of carbon fiber preforming adds
Solid method, can be reinforced for each rack steel structure member.
As shown in Figures 3 and 4, the present invention is according to the shape of the different component of grid structure and connection angle, pre- by carbon fiber
Make and reinforce preformed member accordingly, in wrong vertical complicated grid structure, can easily each component be carried out adding
Gu.
As Fig. 2 institute, the present invention includes preforming main body girth member 1 and preforming union joint girth member 2, to be coated in preforming
Carbon fiber rubber 3 between main body girth member 1 and preforming union joint girth member 2 and treat reinforcing network frame member 4, described preforming is even
Joint reinforcement 2 is connected between two preforming main body girth members 1, and described preforming main body girth member 1 is made and net in advance
The assembly of frame member same shape, including hollow cylindrical, hollow square, flute profile, square, the various shaped steel such as I-shaped,
For different rack components, take out to should size rack component, be fitted in the surface of section bar by HHT higher high tensile glue.
The assembly with rack component same shape that described preforming union joint girth member 2 is made in advance, including conical head, rounded nose,
Bipass, tee pipe fitting, trigonocephaly and t prefix etc. are variously-shaped.Institute's carbon fiber rubber 3 is high temperature high voltage resistant, acid-alkali-corrosive-resisting
Fluoride seccotine with anti-light oxygen aging.
During reinforcing, first each of the rack component outer surface treating reinforcing network frame member 4 is removed dust, by carbon fiber rubber
3 are coated in the outer surface treating reinforcing network frame member 4 and inner surface, preforming main body girth member 1 is wrapped up in be attached to and treats reinforcing network frame member 4
Surfaces externally and internally on, then preforming union joint girth member 2 is wrapped up in respectively be attached to each of rack and treat the two of reinforcing network frame member 4
The outer surface of the conical head at end.
