Description
Technical field
The present invention relates to a kind of composited steel and plastic decking, more particularly, to a kind of steel plastic compount misalignment plate.
Background technology
Composited steel and plastic decking is widely used in current national economy production activity.According to existing patent
Document：1、CN2570350Y；2、CN201015910Y；3、CN201802028U；4、CN102529226A；5、
CN201155187Y；6、CN102350826A；There it can be seen that at present, the domestic composite board for steel plate and plastic plate,
It is found in Patents documents or Network Document.But, in patent few in number or document, it is all typically that low-intensity is general
The composite plate of logical color steel (as document 1,3,4,6) or corrosion resistant plate (as document 2,6) and solid plastic plate, and thickness many
Below 5mm.It is mainly used in building decoration field.These composited steel and plastic deckings are usually three-decker, and top layer and bottom are steel plates, in
Interbed is plastics, is bondd by binding material between steel plate and plastics, and have is certain by carrying out to intermediate plastic layer
Strengthen.Domestic steel plastic compount sheet material is only limitted to general steel plate, general galvanized steel plain sheet (tensile strength is typically in below 200MPa)
