Abstract
The utility model relates to a laminated plastic-coated corrugated steel plate. The laminated plastic-coated corrugated steel plate is characterized in that a corrugated steel plate is taken as a basal body, a plastic corrugated layer is laminated on at least one surface of the front surface and back surface of the basal body, the basal body and the plastic corrugated layer are matched in the corrugated shapes and stuck into a whole, the thickness of the plastic corrugated layer is 0.1-8mm, and the laminated plastic-coated corrugated steel plate is particularly suitable for site construction of large-size culverts.
Description
Technical field
The utility model relates to a kind of superimposed covering and moulds corrugated steel, is fit to fields such as the culvert of large-size in highway and the railway engineering, middle-size and small-size arch bridge, bridge floor cover plate and uses.
Background technology
The galvanizing corrugated steel culvert has been widely used in highway and railway engineering at present, but the corrugated steel tube of diameter more than 2 meters is because superelevation, ultra wide is difficult to whole Transporting; So will split into circular arc sheet to pipeline; After being transported to building-site, carry out assembly unit again, the secondary that assembly unit is carried out outside the galvanizing after accomplishing again is anticorrosion, generally adopts methods such as pitching and mopping; But has only 1.5-3 the service life of pitch and paint; And not wear-resistant, the sandstone in the not anti-rainwater wash away, and are wear-resisting and corrosion resistant performance is poor.And the galvanized layer thickness of steel plate also has only 0.1 millimeter, and is too thin, easily by current and sandstone erosive wear, can not well play the effect of protection steel plate.
Summary of the invention
The utility model is the deficiency that overcomes prior art, provides a kind of superimposed covering to mould corrugated steel, is particularly suitable for the use in the large scale culvert.
The above-mentioned purpose of the utility model is achieved in that a kind of superimposed covering mould corrugated steel; It is characterized in that: be matrix with the corrugated steel; In its tow sides superimposed system surge layer of moulding on the one side at least, both bellows-shaped coupling is also pasted and is one, and the thickness of moulding the system surge layer is 0.1-8mm.
Advantage of the utility model and beneficial effect:
Moulding system ripple cover layer (plastic plate or film) has increased the wearability and the corrosion resistance of corrugated steel; Make that the range of application of corrugated steel is more extensive; Improve the service life of corrugated steel greatly; Can it be bent to large-sized arch or multi-section circular arc shape is spliced into big tubular then as culvert or semicircle and arc foot bridge as required, also can be used as straight sheet material and directly use.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is that the utility model is spliced into columnar sketch map.
The specific embodiment
Referring to Fig. 1; On two surfaces up and down of corrugated steel matrix 3 (or a surface); The plastic corrugated sheet (film) 1 (plastic components can be adjusted according to demand) that superimposed respectively covering one deck shape is identical, thickness is 0.1-8mm, available epoxy or other jointing materials 2 adopt heat to melt and paste and be one between the two.
Fig. 2 covers with Fig. 1 to mould the embodiment that corrugated steel is spliced into pipe.To cover earlier and mould corrugated steel and bend to circular-arcly, the more circular-arc assembly unit of polylith welding (or bolt connection) become pipe, the length that again multistage pipe butt joint (welding or flange connect) one-tenths is needed (Fig. 2 is that three sections pipes dock).The amplification of A among Fig. 2 promptly is Fig. 1.
Claims (2)
1. superimposed covering moulded corrugated steel, it is characterized in that: be matrix with the corrugated steel, in its tow sides superimposed system surge layer of moulding on the one side at least, both bellows-shaped coupling is also pasted and is one.
2. superimposed covering according to claim 1 moulded corrugated steel, it is characterized in that: the thickness of moulding the system surge layer is 0.1-8mm.
