Description
Technical field
The present invention relates to a kind of Landscape Bridge panel, be specifically related to a kind of bridge deck and manufacture method thereof with durability, skid resistance and landscape effect.
Background technology
Along with further going deep into of China's Urbanization Construction, view trestle designs in the elements of landscape in river course, more and more plays indispensable effect, and its function mainly contains: the traffic passageway of the water surface; Hydrophilic medium; View sight line carrier; The waterfront cultural place of collection amusement, leisure, body-building, interchange; Construct river maintenance and view platform between water body and water surface space.The manufactured materials of view trestle is generally anticorrosive wood material and plastic-wood material at present.The urbanization of China also has very large development space, adds that old town transformation beautifies, and view trestle market prospects are wide.
Anticorrosive wood material be by timber after special preservative treatment, there is effect of Perishing prevention, termite-proof, anti-fungi.Anticorrosive wood is the outdoor wood flooring that can be specifically designed to outdoor environment, and can be directly used in the environment contacting with water body, soil.Its shortcoming is mainly that water resistance is poor, and anti acid alkali performance is poor, and uviolresistance is poor, and cracking, need to paint maintenance frequently, and integrated cost is higher.And anticorrisive agent has certain toxicity to human body, there is certain potential safety hazard; Moulding wood is the update material of anticorrosive wood, is taking the biomass fiber such as sawdust, wood chip as primary raw material, a kind of composite material synthetic with plastics.Being known as is green material, but moulds wooden manufacture and still will use timber, is not environment-friendly materials completely.It is also fatal moulding wooden shortcoming, and quality is more crisp, and toughness is inadequate, and impact resistance is not strong, and water suction easily deforms after making moist.
In addition, adopt the landscape bridge engineering of anticorrosive wood and plastic-wood material construction, just less than one or two years, just there is the phenomenon of various damages in completion often, and carrying out secondary maintenance wastes time and energy.If adopt composite material to manufacture Landscape Bridge bridge deck, do not need to build the concrete bridge deck of bottom, structure is simpler, and cost is lower, can significantly save the engineering construction time.But common composite material bridge deck landscape effect is poor, there is view lines unlike anticorrosive wood is the same with plastic-wood material, it is applied in the cordiality sensation that in natural environment, shortage gets close to nature; The conventional method of producing one deck landscape effect (imitative wood grain) at composite material surface has wood grain paint technology and water transfer printing film technology etc., these technology exist cost high, due to rubbing action surface effect be difficult to durable, the not anti-skidding difficult problem such as easily cause that visitor tumbles.
Therefore, need to develop and a kind ofly there is good landscape effect and have durability and the low cost composite material Landscape Bridge panel of skid resistance, the advantage of composite material bridge deck can be fully utilized like this, its application is extended to Landscape Bridge structure field.
Summary of the invention
In order to solve problems of the prior art, the invention provides a kind of bridge deck that have durability, skid resistance and landscape effect that simultaneously possess.Bridge deck of the present invention, having given full play to the exclusive advantage while of composite material bridge deck, also reach excellent landscape effect.
