Abstract
The utility model discloses a steel-plastic drainage pipe with two flat walls, which comprises a pipe wall formed by spirally coiling strip-like board; wherein, the strip-like board comprises a bottom, ridge sections erecting on the bottom and a cap section on the top of the ridges; a steel strip is spirally arranged among the edge sections; and the tops of the cap section and the steel strip are covered with plastic. The steel-plastic drainage pipe is characterized in that the steel strip includes a top section, side sections formed by bending both sides of the top section downwards, and support bottom sections formed by bending the bottom ends of the two side sections inwards. The steel-plastic drainage pipe has high ring stiffness to meet the requirement of drainage pipe, and has the advantages of optimized steel strip structure, shortened length of the support section, reduced consumption of steel strip, reduced cost, reduced weight of the drainage pipe, high corrosion resistance, long service life, high production yield, simple manufacture equipment, and proper diameter.
Description
Technical field
The utility model relates to the drainage equipment in city, specifically a kind of two flat walls steel plastic strip water pipe.
Background technique
The plastic cement winding structure pipe that uses in the urban discharging pipeline is in light weight, corrosion-resistant, frictional resistance is low, and still, its ring stiffness is relatively poor.In recent years, the steel plastic strip water pipe with the steel band reinforced plastics is competitively studied in countries in the world, wherein relatively is typically, and outer surface is undulatory spiral steel plastic strip water pipe.Mould spiral drain as disclosed a kind of steel in the Chinese utility model patent 200720081236.8, roll by the sheet material spiral and to form, have stronger ring stiffness and corrosion resistance, and it is easily manufactured, but the shackle portion of the steel band of wherein inlaying need consume more steel, has improved manufacture cost.
Summary of the invention
The purpose of this utility model is: provide a kind of corrosion-resistant, can satisfy the ring stiffness requirement, and save the two flat walls steel plastic strip water pipe of manufactured materials.
The technical solution of the utility model is:
A kind of two flat walls steel plastic strip water pipe, inside and outside wall is an even surface, comprises the tube wall by banded sheet material helical coil system, and banded sheet material includes the bottom, the spine of on the bottom, holding up, there is cap portion in spine on the top, and ribbon spiral is installed between the spine, is coated with plastic cement in cap portion and steel band top, it is characterized in that, steel band comprises the top, and the both sides at top bending downwards extend to form sidepiece, and the bottom of both sides is bent to form support base to the inside.
Supplementary technology scheme of the present utility model is as follows:
Preferably, the angle at steel band sidepiece and top is greater than 90 °.
Preferably, support base is parallel with the top.
The beneficial effects of the utility model are:
1, ring stiffness height can satisfy the needs of waste pipe;
2, optimize the structure of steel band, shortened the length of supporting part, saved the band steel, reduced cost, also alleviated the weight of waste pipe;
3, the corrosion resistance and good of waste pipe, the life-span is long;
4, the yield rate height of product, manufacturing equipment is simple, and big or small caliber all is fit to;
5, simplified the structure of banded sheet material.

Wherein, reference character: 1 is plastic cement, and 2 is steel band, and 3 is cap portion, and 4 is spine, and 5 is the bottom, and 6 is two flat walls steel plastic strip water pipe, and 7 is clinch, and 21 is sidepiece, and 22 is support base, and 23 is the top.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Specific embodiment of the utility model, as shown in Figure 1, a kind of two flat walls steel plastic strip water pipe 6, inside and outside wall is an even surface, rolls back coating plastic cement by sheet material and steel band 2 and forms.Wherein banded sheet material includes bottom 5, the spine 4 of on bottom 5, holding up, there is cap portion 3 in spine on 4 tops, the both sides of bottom 5 are clinch 7, it is bonding to protect overlap joint when being used for spiral and rolling mutually, as shown in Figure 3, and behind the helical coil panel, steel band 2 is installed between the spine 4, is used to strengthen the ring stiffness of pipeline; Steel band 2 comprises top 23, the both sides at top 23 bending downwards extend to form sidepiece 21, the bottom of both sides 21 is bent to form support base 22 to the inside, as shown in Figure 4 and Figure 5, wherein, a kind of comparatively preferred scheme is: the sidepiece 21 of steel band 2 and the angle at top 23 are greater than 90 °, and support base 22 is parallel with top 23.
After above-mentioned sheet material spiral rolled, be pressed into steel band 2, coated plastic cement 1 at the cap portion 3 of sheet material and steel band 2 tops again and promptly formed two flat walls steel plastic strip water pipe 6 of the present utility model.
Claims (3)
1. two flat walls steel plastic strip water pipe, inside and outside wall is an even surface, comprises the tube wall by banded sheet material helical coil system, and banded sheet material includes the bottom, the spine of on the bottom, holding up, there is cap portion in spine on the top, and ribbon spiral is installed between the spine, is coated with plastic cement in cap portion and steel band top, it is characterized in that, steel band comprises the top, and the both sides at top bending downwards extend to form sidepiece, and the bottom of both sides is bent to form support base to the inside.
