Abstract
The invention discloses an interlayer composite material bridge panel, which comprises a panel, wherein the panel 1 comprises an upper layer and a lower layer; an interlayer is formed between the upper layer panel and the lower layer panel; a plurality of composite material webs are arranged in the interlayer; both sides of the composite material webs are fixedly connected with the upper layer panel and the lower layer panel respectively; a concrete layer is cast onto the upper layer panel; anchoring parts are arranged in the concrete layer; the anchoring parts pass through the concrete layer and are fixedly connected with the upper layer panel integrally, so that a bridge panel system in which a composite material is combined with concrete is formed. The bridge panel has the advantages of light weight, high strength, high rigidity, moisture resistance, corrosion resistance, peeling resistance, convenience in transportation, and easiness, convenience and rapidness in splicing construction. The bridge panel is suitable for rapidly building permanent bridge panel projects, and can be applied to the fields of temporary rescue and relief work, military rush construction and the like.
Description
Technical field
The present invention relates to a kind of bridge deck, specifically relate to a kind of sandwich-type composite material bridge deck.
Background technology
Traditional bridge deck structure adopts reinforced concrete structure form more, conducts oneself with dignity larger, and construction is complicated, the cycle is long, and corrosion resistance is poor.In addition, under long-term load-bearing environment or when earthquake disaster occurs, concrete structure bridge deck easily crack or destroy, and cause potential safety hazard.For above-mentioned shortcoming, can adopt the bridge deck of composite material, and the composite material bridge deck of at present domestic and international up-to-date proposition, mostly be the glass fiber reinforced plastics hollow bridge deck of pultrusion, but pultrude process is difficult to one-shot forming Large bridge panel construction, need numerous and diverse operations such as extra increase is gluing, winding.
Summary of the invention
The object of the invention is, for overcoming above-mentioned the deficiencies in the prior art, provides a kind of sandwich-type composite material bridge deck, and this panel is applicable to Fast Construction permanent bridge panel engineering, also can be used for the engineering fields such as interim disaster relief and rescue, military rush construction.
To achieve these goals, the technical solution used in the present invention is: a kind of sandwich-type composite material bridge deck, comprise panel, described panel is divided into two-layer up and down, between upper and lower two-layer panel, be provided with laminboard layer, in laminboard layer, be provided with some composite material webs, the both sides of composite material web are fixedly connected with upper and lower two-layer panel respectively, on upper deck panels, build layer of concrete, in layer of concrete, be provided with anchoring piece, anchoring piece is fixedly connected into one through layer of concrete and upper deck panels, forms the combined bridge deck system of composite material and concrete.
Preferably, the fiber layer of cloth that described panel adopts be multiaxis to glass fabric, the resin that panel adopts is epoxy resin or phenolic resins.
Further, described laminboard layer is polyurethane foam, polyvinyl chloride foam or carbon foam.
Further, the angle of described composite material web and panel is 40 ° to 50 °.
Adopt the invention of the technical program, its beneficial effect is: bridge deck of the present invention are lightweight, intensity is high, rigidity is large, moistureproof, corrosion-resistant, antistripping, convenient transport, assembling construction are simple, convenient and rapid, bridge deck of the present invention are not only applicable to Fast Construction permanent bridge panel engineering, and can be used for the engineering fields such as interim disaster relief and rescue, military rush construction.In addition, this composite material bridge deck not only can suitability for industrialized production, and can produce by the driving requirement of bridge floor the sandwich-type composite material bridge deck of different size and type.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the A-A sectional view of Fig. 1;
In figure: 1, panel; 2, layer of concrete; 11, composite material web; 21, anchoring piece.
The specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
Referring to Fig. 1 and Fig. 2, sandwich-type composite material bridge deck of the present invention, comprise panel 1, described panel 1 is divided into two-layer up and down, between upper and lower two-layer panel 1, be provided with laminboard layer, in laminboard layer, be provided with some composite material webs 11, the both sides of composite material web 11 are fixedly connected with upper and lower two-layer panel 1 respectively, on upper deck panels 1, build layer of concrete 2, in layer of concrete, be provided with anchoring piece 21, anchoring piece is fixedly connected with integral with upper deck panels 1 through layer of concrete, form the combined bridge deck system of composite material and concrete.The fiber layer of cloth that described panel 1 adopts be multiaxis to glass fabric, the resin that panel 1 adopts is epoxy resin or phenolic resins.Described laminboard layer is polyurethane foam, polyvinyl chloride foam or carbon foam.Described composite material web 11 is 40 ° to 50 ° with the angle of panel 1.
Above are only a kind of embodiment of the present invention; not in order to limit the present invention; those skilled in the art can make various changes and improve said structure; all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
