Abstract
The utility model discloses a fiber reinforce plastic (FRP) combined plate, which comprises a flat FRP plate, wherein two or more inverted-T-shaped perforated FRP connecting pieces are stuck to the flat FRP plate; sand is paved on the surfaces of the flat FRP plate and the FRP connecting pieces; FRP perforated ribs are inserted into holes of the FRP connecting pieces; FRP plate surface ribs are arranged above the FRP perforated ribs; the flat FRP plate, the FRP connecting pieces, the FRP perforated ribs and the FRP plate surface ribs constitute an FRP flat plate bracket; and concrete is poured on the FRP flat plate bracket. A temporary support does not need to be erected, the construction is convenient, and the FRP combined plate has the characteristics of small dead weight, high bearing capability, high corrosion resistance, simple structure and convenience in use.
Description
Technical field
The utility model belongs to field of civil engineering, relates to building unit, relates in particular to a kind of FRP compoboard.
Background technology
Used bridge deck are generally traditional armored concrete slab in the bridge engineering, after the steel plate-concrete compoboard has appearred again, but traditional armored concrete slab still is the steel plate-concrete compoboard all exists a difficult problem---the corrosion problem of reinforcing bar and steel, this is domestic and international civil engineering field problem of being concerned about and the challenge that faces always.Use the area of deicer salts and the area of bordering on the sea in the winter time in a large number, this type of problem is particularly outstanding.Existing engineering practice shows, is the required reinforcing of the normal function of use that keeps structure and the maintenance cost several times of the cost of structure normally own.Therefore, it is important and urgent that development and research have showing bridge construction day of durability and low maintenance expense, and adopt have good durability the FRP material as an alternative material can efficiently and effectively improve and solve the endurance issues of bridge construction.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the purpose of this utility model is to provide a kind of FRP compoboard, and it need not to set up interim support, easy construction, and it is less to conduct oneself with dignity, and supporting capacity is strong, and corrosion resistance and good has characteristics simple in structure, easy to use.
In order to achieve the above object, the technical solution adopted in the utility model is:
The FRP compoboard, comprise flat FRP plate 1, be pasted with two or more inverted T shape perforate FRP connectors 2 on the flat FRP plate 1, the surperficial sanding of flat FRP plate 1 and FRP connector 2, be penetrated with FRP perforation muscle 3 in the hole of FRP connector 2, above FRP perforation muscle 3 FRP plate gluten 4 is set, described flat FRP plate 1, FRP connector 2, FRP perforation muscle 3 and FRP plate gluten 4 are formed FRP flat bracket, concreting 5 on described FRP flat bracket.
Described FRP connector 2 is a plurality of.
Described FRP perforation muscle 3 is a plurality of.
Described FRP connector 2 equidistantly distributes.
The utility model compared with prior art has the following advantages:
1) each member can prefabricatedly be finished, and the scene is used in combination, and both can ensure the quality of products, again reduction of erection time greatly.
2) flat FRP plate can play template action, has very big rigidity after being stained with perforate inverted T shape FRP connector, therefore, need not to set up interim support, easy construction.
3) rigidity of compoboard and intensity strengthen greatly, and stress performance is better.
4) with respect to traditional reinforcing bar and steel, it is lighter to conduct oneself with dignity, and is particularly useful for the long-span bridge panel and lacks girder bridge and the bigger bridge design trend of girder spacing at present to satisfy.
5) corrosion resistance and good, good endurance.
6) has good anti-fatigue performance.
7) can be designed to Orthogonal Double to same sex plate, more effectively improve supporting capacity.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further details.
As shown in drawings, the utility model is the FRP compoboard, comprise flat FRP plate 1, be pasted with two or more inverted T shape perforate FRP connectors 2 on the flat FRP plate 1, the surperficial sanding of flat FRP plate 1 and FRP connector 2 is penetrated with FRP perforation muscle 3 in the hole of FRP connector 2, above FRP perforation muscle 3 FRP plate gluten 4 is set, described flat FRP plate 1, FRP connector 2, FRP perforation muscle 3 and FRP plate gluten 4 are formed FRP flat bracket, concreting 5 on described FRP flat bracket.
For ease of processing, the quantity of FRP connector 2 and FRP perforation muscle 3 all is that plural number and described FRP connector 2 equidistantly distribute.
The FRP-concrete combined board adopts the FRP section bar to substitute traditional reinforcing bar and steel, can greatly improve and effectively solve the crucial difficult problem of durability of reinforced concrete bridge deck plate; Relatively ordinary reinforced concrete can reduce the bridge construction deadweight, thereby effectively alleviate the bridge construction geological process, more can reduce the bridge design load significantly, thereby can bigger increase bridge limit span; In combined bridge deck, the FRP section bar is positioned at the tensile region, be not prone to secondary buckling and destroy, the high strength of FRP material can be not fully exerted and utilize, and is highly suitable for the long-span bridge panel and lacks girder bridge and the bigger bridge design trend of girder spacing at present to satisfy; Because the bonding elongated layout of perforate ⊥ type FRP connector adopts the FRP muscle simultaneously, can effectively improve the rigidity and the intensity of compoboard, stress performance is better.
In the utility model, flat FRP plate can play template action, has very big rigidity after being stained with perforate soil type FRP connector, therefore, need not to set up interim support, easy construction.
The most of manufacturing process of compoboard of the present utility model can be prefabricated in the factory and finish, therefore, promptly can fine assurance fabricating quality, can shorten the construction period greatly again, has significant advantage, especially the repairing maintenance works for bridge has remarkable meaning more, has quite big application prospect simultaneously in engineerings such as long-span bridge panel, large bay floor, basement roof.
