Summary of the invention
The composite material bridge deck that provides a kind of novel civilian and national defence to be badly in need of is provided at above-mentioned the deficiencies in the prior art.
Purpose of the present invention can reach by following measure:
A kind of composite material bridge deck, it comprises core 1, the two sides of core 1 are provided with the panel 2 that fiber layer of cloth and resin solidification form, and the composite material web 4 that is the resin web 3 of 45 ° of-90 ° of regular arrangement with panel 2 or adopts cloth and resin solidification formation is set in core 1.
Described core 1 material is Balsa wood, paulownia wood, China fir, oak, veneer, polyurethane foam, polyvinyl chloride foam or carbon foam.
The fiber layer of cloth that described panel 2 adopts is: single shaft to, twin shaft to or multiaxis to carbon fiber, glass fiber, basalt fibre, aramid fiber or hybridization cloth; The resin that panel 2 adopts is: unsaturated polyester (UP), vinylite, epoxy resin or phenolic resins.
Described panel 2 is provided with layer of concrete 5, and layer of concrete 5 is combined as a whole by shear connector 6 and panel 2, perhaps builds in panel 2 tops, forms the combined bridge deck system of composite material-concrete.
Described shear connector 6 is nail, sheet material or Z-shaped section bar.
Above-mentioned composite material bridge deck can adopt hand to stick with paste technology, vacuum bag moulding process, vacuum guiding and forming technique preparation.
The present invention has following advantage:
Composite material bridge deck provided by the invention is compared with other products, its maximum characteristics are: in light weight, the intensity height, rigidity is big, moistureproof, corrosion-resistant, antistripping, convenient transport, assembling construction are simple, convenient and rapid, can be used for building and repairing of emergency road in national defence and the civil engineering.But this composite material bridge deck suitability for industrialized production simultaneously can be by the bridge deck of driving requirements production different size.
