The utility model is to adopt following technological scheme to realize above-mentioned purpose: a kind of steel rib reinforced plastic hollow wall band; It is characterized in that; Comprise upper strata plastic layer, lower floor's plastic layer and the strengthening rib more than two; Said strengthening rib more than two is vertically connected between upper strata plastic layer and the lower floor's plastic layer and constitutes hollow structure; This strengthening rib more than two equidistantly distributes along the strip width direction; And the strengthening rib that is positioned at the band both sides is respectively steel plastic composite structure and plastics strengthening rib, and the strengthening rib between band two side stringers is steel plastic composite structure, and the wall thickness sum of said strengthening rib in the band both sides equals the wall thickness of each strengthening rib between band two side stringers.
As further specifying of such scheme:
Preferably, the cross section of said adjacent two strengthening rib and upper strata plastic layer and the hollow structure that lower floor's plastic layer constituted is trapezoidal for rectangle or four rounding of angle angles oval, four rounding of angle angles.
Preferably, said steel plastic composite structure is the composite structure of steel disc for the outer layer plastic core.
Preferably, four of said band jiaos is the chamfering of R2～R10.
Preferably, the centre distance of said adjacent two strengthening rib is 30mm～100mm.
Preferably, the strengthening rib of said steel plastic composite structure is 1～3, and promptly strengthening rib adds up to 2～4.
Preferably, said plastics are polyethylene.
A kind of steel rib reinforced plastic hollow wall entwining tube is made up of above-mentioned band spiral winding, and the side of adjacent band is bonding by the polyethylene or the polyethylene hot-melt adhesive of fusion.
The beneficial effect that the utility model adopts above technological scheme to reach is: the described steel rib of the utility model reinforced plastic hollow wall entwining tube and profile band thereof; Not only be convenient to implement; Can significantly improve the ring stiffness of entwining tube; And the steel disc in the steel plastic composite structure because of fully by plastic overmold, solved the problem of steel disc corrosion-vulnerable.
