Abstract
The utility model relates to a metal reinforcement structured wall plastic tube, which is characterized in that the metal reinforcement structured wall plastic tube is formed through winding plastic special-shaped strips with metal ribs, lapping seams of the strips for winding are bonded through plastics or hot melt adhesives, and a dentiform or snap-on lap joint is adopted by the lapping seams of the strips for winding. The metal reinforcement structured wall plastic tube is also characterized in that the dentiform lap joint adopts triangular teeth, saw-shaped teeth, trapezoid teeth, square teeth or combined teeth of any two kinds of teeth, and the snap-on lap joint adopts a ball head type, an inverted triangle type, an inverted trapezoid type, a swallowtail type or other snap-on types. The size, thickness, height and angle of a structure adopted by the seam for lap joint is variable according to the metal reinforcement structured wall plastic tubes with different diameters. The metal reinforcement structured wall plastic tube has the advantages that contact area of a bond surface is enlarged, seam connection is more reliable and firmer through a binder, and axial tensile strength of a pipe is enhanced at the same time, therefore seam crossings are prevented from being easily split or leak during the use of the metal reinforce structure wall plastic tube.
Description
Technical field
The utility model is involved in a kind of structured wall plastic pipe, and particularly a kind of metal strengthens the structured wall plastic pipe.
Background technique
The draining drain pipe is a kind of no pressure piping, mainly bears the load from the tubing outside.The popular steel of existing market is moulded and is twined the draining drain pipe the earliest by KraussMaffei and Australian tubing manufacturer Plastream cooperative development, is called the SRP pipe abroad.For the plastic tube that bears external load, the ring stiffness of tubing is an important indicator, and steel is moulded and twined waste pipe combination property the best, and it is minimum that it produces materials, the ring stiffness height, and equipment cost is low.Patents such as domestic ZL200520112528.4, ZL200510082911.4 have also been introduced a kind of similar steel and have been moulded entwining tube, but there is following shortcoming: because its pipe is to be entwined with the plastic shaped band that has metal ribs, connection part between band has adopted flush weld or bonding, and this is a weak link.Because seam is longer, the reliability of connection is difficult to control and measures in process of production, and the axial tensile strength of tubing is also lower, seepage easily in the using process.
Summary of the invention
Problem to be solved in the utility model is exactly to overcome and avoid above-mentioned shortcoming, and it is firmly reliable to provide a kind of seam to connect, the tensile strength height that tubing is axial, and the metal that is not easy seepage in the using process strengthens the structured wall plastic pipe.The utility model designs a kind of metal and strengthens the structured wall plastic pipe, it is characterized in that: be entwined by the plastic shaped band that has metal ribs, pass through plastics or hot melt adhesive bonding in overlapping the slot place of its winding.It is characterized in that: dentation or seizing type overlap joint are adopted in overlapping the slot place of winding.It is characterized in that: the dentation overlap joint is the combination of lance tooth, saw shape tooth, stepped tooth, square shaped teeth or above any two kinds of teeth.It is characterized in that: seizing type overlap joint is bulb formula, T form, inverted triangle formula, fall trapezoidal formula, other buckle form of dovetail type.Strengthen the structured wall plastic pipe according to the metal of different-diameter, its seam overlap joint the structure that can adopt size, thickness, highly, angle is transformable.The utility model has the advantages that the area of contact that has increased adhesive surface, it is more reliable firm to allow Bond that seam is connected, increased the axial tensile strength of tubing simultaneously, make metal strengthen the structured wall plastic pipe in use seam crossing be not easy cracking, also be not easy seepage.

Embodiment
A kind of metal strengthens the structured wall plastic pipe, it is characterized in that: be entwined by the plastic shaped band that has metal ribs, and firm in overlapping the slot place of its winding by plastics or hot melt adhesive bonding.It is characterized in that: dentation or seizing type overlap joint are adopted in overlapping the slot place of winding.It is characterized in that: the dentation overlap joint is the combination of lance tooth, saw shape tooth, stepped tooth, square shaped teeth or above any two kinds of teeth.It is characterized in that: seizing type overlap joint is bulb formula, T form, inverted triangle formula, fall trapezoidal formula, other buckle form of dovetail type.Strengthen the structured wall plastic pipe according to the metal of different-diameter, its seam overlap joint the structure that can adopt size, thickness, highly, angle is transformable.
Figure 1 shows that existing metal strengthens the profile schematic representation of structured wall plastic pipe, Fig. 2 is the generalized section that existing metal strengthens the structured wall plastic pipe.11 is the flat limit of overlap joint of heterotypic strip, the 12nd, and the plastics of heterotypic strip, the 13rd, the Bond of band seam crossing, the 14th, the metal strength bar of band.
Fig. 3---in 5,1 is that the utility model metal strengthens the structured wall plastic pipe, and 2 be the metal strength bar, and Fig. 3 is the plastic shaped band schematic cross-section of the utility model metal ribs enhancing, and 5 and 7 is dentation structures of joint, the utility model heterotypic strip both sides.Fig. 4 is the sectional view that the utility model metal strengthens the structured wall plastic pipe, the 6th, and the Bond of dentation joint between the band after twining.Fig. 5 is the sectional view that the utility model metal strengthens the another kind of seizing type joint form of structured wall plastic pipe, the 8th, the groove of seizing type overlap joint, the 9th, the bulb shape convex of seizing type overlap joint, bulb shape convex 9 just in time is stuck in the groove 8 after twining, and squeezes into Bond 6 in its slit.Adopt the connecting means of these two kinds of forms, not only increased the area of contact of adhesive surface, it is more reliable firm to allow Bond that seam is connected, and has also increased the axial tensile strength of tubing simultaneously, make metal strengthen the structured wall plastic pipe in use seam crossing be not easy cracking, more difficult seepage.Other joint form that the utility model can adopt can be the combination of lance tooth, saw shape tooth, stepped tooth, square shaped teeth or above any two kinds of teeth; The seizing type joint form can be bulb formula, T form, inverted triangle formula, other buckle forms such as trapezoidal formula, dovetail type of falling, as Fig. 6---and shown in 14.
