Abstract
The invention discloses an FRP bridge deck. The FRP bridge deck comprises multiple FRP component units. The FRP component units are sequentially tiled and stacked in a row in the length direction of a bridge, and the length of the FRP component units is the bridge width of the bridge. FRP reinforcing ribs used for reinforcing bearing of the bridge are arranged at the end of the FRP component unit arranged initially. By the adoption of the FRP bridge deck, the erection time of a bridge box can be greatly saved, bearing of a bridge body can be reinforced, and more importantly, energy saving and environmental friendliness are achieved.
Description
Technical field
The present invention relates to a kind of floorings, more particularly to a kind of FRP floorings.
Background technology
At present, the floorings of existing bridge adopt concrete Pouring form mostly.But this conventional bridge structure,
Not only body of a bridge deadweight is very heavy, and difficulty of construction is big, and long using the concrete cast floorings process-cycle, time-consuming, and applies
Work environment is also very poor.
The content of the invention
In view of the drawbacks described above of prior art, the present invention provides one kind and can save construction period and can improve construction ring
The FRP floorings in border, its feature is that the FRP floorings include some FRP member units, each FRP member units edge
The length direction of bridge is folded in a row tiling set laying successively, and the length of the FRP member units is the bridge width of bridge；Initial
The termination of the FRP member units laid is provided with the FRP reinforcements for strengthening bridge bearing.FRP materials in the present embodiment
Material (fibre reinforced composites are the abbreviation of English fiber reinforced polymer) is material commonly known in the art
Material, the FRP material is commercially available.FRP composites be mixed according to a certain percentage with matrix material by fibrous material after shape
Into high-performance section bar material.Its light weight and hard, non-conductive, high mechanical strength, recycle it is few, it is corrosion-resistant.Due to what is used
Resin variety is different, therefore has the title of organic toughened glass, fiber glass epoxy, phenolic fiberglass reinforced plastics.It is unique that the present invention is based on FRP
Mechanical property and adapt to modern project structure to greatly across, the demand of towering, heavily loaded, lightweight development the characteristics of, therefore by its
As the main body stress framework of bridge.
In certain embodiments, the floorings are using FRP floorings obtained in FRP material pultrusion.In the present embodiment
Pultrusion processing technology can be compared with known pultrusion processing technology in technology.
In certain embodiments, each FRP member units are spelled to take side by side and formed by two equilateral triangle frameworks
Diamond.Certainly, replace as other, each FRP member units can also be the FRP components of other hollow structures, this reality
It is only merely a kind of example to apply example.
On the basis of common sense in the field is met, above-mentioned each optimum condition can be combined, and obtain final product each preferable reality of the present invention
Apply example.
Beneficial effects of the present invention：Using the present invention, can not only greatly save the time that bridge tank tower sets, quickening construct into
Degree, and body of a bridge load-bearing can be reduced, what is more important also energy-conserving and environment-protective.
The technique effect of the design, concrete structure and generation of the present invention is described further below with reference to accompanying drawing, with
It is fully understood from the purpose of the present invention, feature and effect.
Description of the drawings
Fig. 1 is the FRP member unit plane structure charts of the present invention.
Fig. 2 is the structure chart of the floorings length direction of the present invention.
Description of reference numerals：FRP member units 1；FRP floorings 10
Specific embodiment
Enumerate preferred embodiment below, and combine accompanying drawing becoming apparent from intactly illustrating the present invention.
Embodiment
The purpose of the present invention is achieved through the following technical solutions：As shown in Fig. 1～Fig. 2, what the present embodiment was provided
The FRP floorings 10 include some FRP member units 1, and each FRP member units 1 are in successively along the length direction of bridge
One row tiling is folded to set laying, and the length of the FRP member units 1 is the bridge width of bridge；In the initial FRP components list laid
The termination of unit 1 is provided with the FRP reinforcements for strengthening bridge bearing.
(fibre reinforced composites are English fiber reinforced polymer to FRP material in the present embodiment
Abbreviation) it is material commonly known in the art.FRP composites are mixed according to a certain percentage with matrix material by fibrous material
The high-performance section bar material for being formed afterwards, its light weight and hard, non-conductive, high mechanical strength recycle few, corrosion-resistant FRP material
For commercially available.Due to the resin variety that used it is different, therefore have organic toughened glass, fiber glass epoxy, phenolic fiberglass reinforced plastics it
Claim.The present invention is based on the unique mechanical properties of FRP, and adapts to modern project structure to greatly across, towering, heavily loaded, lightweight
The characteristics of demand of development, therefore as the main body stress framework of bridge.
As shown in figure 1, each FRP member units 1 are to be spelled side by side to take the rhombus for being formed by two equilateral triangle frameworks
Frame.
Certainly, replace as other, each FRP member units can also be the FRP components of other hollow structures, this reality
It is only merely a kind of exemplary statement to apply example.
The floorings of the present invention are using FRP floorings obtained in FRP material pultrusion.Pultrusion in the present embodiment adds
Work technique can be compared with known pultrusion processing technology in technology.
Therefore, using the FRP floorings of the present invention, the time of bridge erection can be not only greatlyd save, and the body of a bridge can be reduced
Load-bearing, what is more important also energy-conserving and environment-protective.
Each preferred embodiment of the present invention described in detail above.It should be appreciated that one of ordinary skill in the art
Just many modifications and variations can be made with design of the invention without the need for creative work.Therefore, all skills in the art
Art personnel can be obtained by logical analysis, reasoning, or a limited experiment on the basis of existing technology under this invention's idea
Technical scheme, all should be in the protection domain being defined in the patent claims.
