Abstract
The invention discloses an FRP bridge structure. The FRP bridge structure comprises a bridge panel for forming a carrier pavement of a bridge, two bridge abutments for supporting the bridge panel and a plurality of main beams which are arranged at the bottom of the bridge panel at intervals; each main beam is an FRP main beam prepared by mold pressing an FRP material; the bridge panel is an FRP bridge panel formed by stretching and extruding the FRP material, the FRP bridge panel comprises a plurality of FRP component units, the FRP component units are successively laid and stacked in a column along the length direction of the bridge, and the length of the FRP component unit is the width of the bridge; the end of a firstly arranged FRP component unit is provided with an FRP reinforcing rib for reinforcing the load bearing of the bridge. By adopting the FRP bridge structure, the construction period of the bridge can be greatly reduced, the engineering difficulty can be reduced, energy conservation and environmental protection can be realized, and the operating environment of the building construction can be greatly improved.
Description
Technical field
The present invention relates to bridge construction field, more particularly to a kind of FRP bridge structures based on FRP material.
Background technology
At present, existing bridge is set up using steel plate and concrete and is formed mostly.For example, in bridge erection operation, bridge
The girder of beam has what is made using steel plate, also has using steel plate plus concrete for making.And be mostly to adopt coagulation for floorings
Soil cast is obtained.
But this conventional bridge structure, to be conducted oneself with dignity by the body of a bridge very heavy, difficulty of construction is big, and pours into a mould bridge using concrete
The panel process-cycle is long, time-consuming, and construction environment is very poor.
The content of the invention
In view of the drawbacks described above of prior art, the present invention provides a kind of time saving and energy saving and energy-conserving and environment-protective FRP bridges knot
Structure, its feature is that it includes：For forming the floorings on the carrying road surface of bridge, two being used to support the bridge of the floorings
Platform and some space-stop racks are located at the girder of the bottom of the floorings；The floorings are using FRP obtained in FRP material pultrusion
Floorings, the girder is using the obtained FRP girders of FRP material molding；The FRP floorings include some FRP components lists
Unit, each FRP member units are folded successively in string tiling along the length direction of bridge and set laying, the FRP member units
Length is the bridge width of bridge；The FRP being provided with for strengthening bridge bearing in the termination of the initial FRP member units laid adds
Strong muscle.(fibre reinforced composites are the contracting of English fiber reinforced polymer to FRP material in the present embodiment
Write) it is material commonly known in the art, the FRP material is commercially available.FRP composites are by fibrous material and matrix material
The high-performance section bar material that material is formed after mixing according to a certain percentage.The material light weight and hard, non-conductive, high mechanical strength, reclaim
It is corrosion-resistant using few.The present invention be based on the excellent mechanical properties of FRP and adapt to modern project structure to greatly across, it is towering,
The characteristics of heavy duty, demand of lightweight development, therefore as the main body stress framework of bridge.
In certain embodiments, each FRP member units are to be spelled to take the FRP rhombuses 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, the present embodiment
Only it is merely a kind of exemplary statement.
In certain embodiments, the section of the FRP girders is u-shaped, rectangle or trapezoidal.Certainly, as a kind of replacement,
FRP girders can also be the section structure of other any geometries.
In certain embodiments, the top surface of the FRP floorings is provided with retinasphal pave-load layer.
In certain embodiments, the FRP reinforcements are L-shaped.Wherein, the FRP reinforcements are also using FRP material system
.
On the basis of common sense in the field is met, above-mentioned each optimum condition, can combination in any, obtain final product each preferable reality of the present invention
Apply example.
Beneficial effects of the present invention：Using the present invention, the time of bridge erection can be not only greatlyd save, and it is difficult to reduce engineering
Degree, 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 facade layout drawing of the bridge structure along span direction of the present invention.
Fig. 2 is the span centre cross-section structure of bridge of the present invention.
Description of reference numerals：FRP floorings 1；FRP girders 2；Abutment 3；Retinasphal pave-load layer 4
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
FRP bridge structures, if including for formed bridge carrying road surface floorings, two be used for support the floorings abutment and
Girder of the dry space-stop rack located at the bottom of the floorings；The floorings are using FRP bridge floors obtained in FRP material pultrusion
Plate, the girder is using the obtained FRP girders of FRP material molding；The FRP floorings include some FRP member units, respectively
The FRP member units are folded successively in string tiling along the length direction of bridge and set laying, and the length of the FRP member units is
The bridge width of bridge；The FRP reinforcements for strengthening bridge bearing are provided with the termination of the initial FRP member units laid
(not shown).
(fibre reinforced composites are English fiber reinforced polymer to FRP material in the present embodiment
Abbreviation) it is material commonly known in the art, the FRP material is commercially available.FRP composites are by fibrous material and matrix
The high-performance section bar material that material is formed after mixing according to a certain percentage.Light weight and hard, non-conductive, high mechanical strength, recycle
It is few, it is corrosion-resistant.
The present invention be based on the excellent mechanical properties of FRP and adapt to modern project structure to greatly across, it is towering, heavily loaded,
The demand of lightweight development, therefore as the main body stress framework of bridge.
Exemplary, each FRP member units can be to be spelled to take the FRP rhombuses 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, and here is no longer
Enumerate.
It is exemplary, according to tonnage of bridge and it is actually needed, the section of the FRP girders can be U-shaped, rectangle or ladder
Shape.Certainly, as a kind of replacement, FRP girders can also be the section structure of other any geometries.
In Specific construction, the FRP reinforcements can be L-shaped FRP reinforcements.Of course, the FRP reinforcements
It is using obtained in FRP material.
After floorings laying is completed, in the top surface of the FRP floorings retinasphal pave-load layer 4 is additionally provided with.To
The flat bridge floor that formation is walked for vehicles or pedestrians.
Therefore, using the present invention, the time of bridge erection can be not only greatlyd save, and reduces engineering difficulty, it is even more important
Be also energy-conserving and environment-protective, substantially improve the construction environment of bridge operation.
