The problem of fiber reinforced anti-external disturbance ability.
This utility model is achieved in that a kind of bridge carbon fiber reinforcing concrete structure, including concrete base layer,
It is located at the lightweight concrete repair layer of described concrete base layer outer surface, is covered on described lightweight concrete successively
The carbon fiber stretch-resistant layer of repair layer outer surface, carbon fiber reinforcement layer, be sprayed at described carbon fiber reinforcement successively
Layer the polypropylene fiber net protective layer of outer surface, composite aluminium-magnesium-silicate thermal insulation layer, polyurethane water-proof layer；Wherein,
It is additionally provided with steel wire in described lightweight concrete repair layer.
Preferably, described polypropylene fiber net protective layer, composite aluminium-magnesium-silicate thermal insulation layer, polyurethane water-proof layer
Thickness be respectively 4.2mm, 4.5mm, 1.9mm.
Preferably, also spray between described polypropylene fiber net protective layer and described composite aluminium-magnesium-silicate thermal insulation layer
Having fire resistant coating, described fire resisting covering is 2mm.
This utility model overcomes the deficiencies in the prior art, it is provided that a kind of bridge carbon fiber reinforcing concrete structure, one side
Face arranges the lightweight concrete repair layer being embedded with steel wire on the concrete base layer of bridge, fine to improve carbon
Dimension stretch-resistant layer, carbon fiber reinforcement layer and the attachment force of concrete base layer, it is to avoid because of concrete base layer fineness
The carbon fiber stretch-resistant layer, the carbon fiber reinforcement layer that cause not can not be the most bonding；On the other hand arrange
Polypropylene fiber net protective layer, composite aluminium-magnesium-silicate thermal insulation layer, polyurethane water-proof layer increase carbon fiber tension
Stretch layer, the protection of carbon fiber reinforcement layer, reduce carbon fiber stretch-resistant layer, carbon fiber reinforcement layer by external rings
The impact in border.

The orientation of the instruction such as " clockwise ", " counterclockwise ", " axially ", " radially ", " circumferential " or position
Relation of putting, for based on orientation shown in the drawings or position relationship, is for only for ease of the description present invention and simplification is retouched
State rather than indicate or imply that the device of indication or element must have specific orientation, with specific orientation
Structure and operation, be therefore not considered as limiting the invention.
Additionally, term " first ", " second " are only used for describing purpose, and it is not intended that instruction or dark
Show relative importance or the implicit quantity indicating indicated technical characteristic.Thus, define " first ",
The feature of " second " can express or implicitly include at least one this feature.In describing the invention,
" multiple " are meant that at least two, such as two, three etc., unless otherwise expressly limited specifically.
In this utility model, unless otherwise clearly defined and limited, term " install ", " being connected ",
" connect ", the term such as " fixing " should be interpreted broadly, and connects for example, it may be fixing, it is also possible to be
Removably connect, or integral；Can be to be mechanically connected, it is also possible to be electrical connection；Can be to be joined directly together,
Can also be indirectly connected to by intermediary, can be connection or two elements mutual of two element internals
Interactively, unless otherwise clear and definite restriction.For the ordinary skill in the art, can basis
Concrete condition understands above-mentioned term concrete meaning in the present invention.
In this utility model, unless otherwise clearly defined and limited, fisrt feature second feature " on "
Or D score can be that the first and second features directly contact, or the first and second features are by between intermediary

Referring to Fig. 1, embodiment of the present utility model provides a kind of bridge carbon fiber reinforcing concrete structure, including mixing
Solidifying soil matrix layer 1, is located at the lightweight concrete repair layer 2 of described concrete base layer 1 outer surface, is covered on successively
The carbon fiber stretch-resistant layer 3 of described lightweight concrete repair layer 2 outer surface, carbon fiber reinforcement layer 4, spray successively
It is applied to the polypropylene fiber net protective layer 5 of described carbon fiber reinforcement layer 4 outer surface, composite aluminium-magnesium-silicate heat insulation
Layer 6, polyurethane water-proof layer 7；Wherein, it is additionally provided with steel wire 8 in described lightweight concrete repair layer 2.
Concrete, the concrete base layer 1 of bridge arranges the lightweight concrete repairing being embedded with steel wire 8
Layer 2, to improve carbon fiber stretch-resistant layer 3, carbon fiber reinforcement layer 4 and the attachment force of concrete base layer 1, keeps away
Exempt from carbon fiber stretch-resistant layer 3 that the fineness after polishing because of concrete base layer 1, flatness cause not,
Carbon fiber reinforcement layer 4 can not be the most bonding；Polypropylene fiber net protective layer 5, complex silicate are set simultaneously
Magnalium thermal insulation layer 6, polyurethane water-proof layer 7 are strengthened carbon fiber stretch-resistant layer 3, the guarantor of carbon fiber reinforcement layer 4
Protect, it is to avoid carbon fiber stretch-resistant layer 3, carbon fiber reinforcement layer 4 are because being led by car body collision, masses hit etc.
Cause to damage, then cause shorten the service life of bridge structure.
In order to reduce because spray coating polypropylene fleece protective layer 5, composite aluminium-magnesium-silicate thermal insulation layer 6, polyurethane are prevented
Water layer 7 and cause cost to increase, the load-bearing of bridge structure increases, described in the present embodiment, polypropylene fiber net is protected
Sheath 5, composite aluminium-magnesium-silicate thermal insulation layer 6, polyurethane water-proof layer 7 thickness unsuitable blocked up, typically can gather
Tacryl net protective layer 5, composite aluminium-magnesium-silicate thermal insulation layer 6, the thickness of polyurethane water-proof layer 7 are respectively provided with
For for 4.2mm, 4.5mm, 1.9mm.
Due to bridge in actual application easily by car body collision, and car body collision is it may happen that on fire, enters
And cause bridge on fire, therefore described polypropylene fiber net protective layer 5 and described composite aluminium-magnesium-silicate thermal insulation layer 6
Between be also coated with fire resistant coating 9, described fire resistant coating 9 thickness is 2mm.
Compared to the shortcoming and defect of prior art, this utility model has the advantages that and on the one hand exists
The lightweight concrete repair layer being embedded with steel wire is set on the concrete base layer of bridge, anti-to improve carbon fiber
Tensile layer, carbon fiber reinforcement layer and the attachment force of concrete base layer, it is to avoid because concrete base layer fineness is inadequate
And the carbon fiber stretch-resistant layer caused, carbon fiber reinforcement layer can not be the most bonding；On the other hand poly-third is arranged
Alkene fleece protective layer, composite aluminium-magnesium-silicate thermal insulation layer, polyurethane water-proof layer increase to carbon fiber stretch-resistant layer,
The protection of carbon fiber reinforcement layer, minimizing carbon fiber stretch-resistant layer, carbon fiber reinforcement layer are by the shadow of external environment condition
Ring.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model,
All any amendment, equivalent and improvement etc. made within spirit of the present utility model and principle, all should
