Abstract
The utility model discloses a netlike steel bar enhancement type single hollow figured steel strip steel-plastic composite tube material. The inner wall of a tube is a single hollow plastic plate strip which is formed by lapping and adhering inner edges, which are extended to two sides respectively, by winding and adhesion; an enhanced figured steel strip is wound and embedded in a clamping groove which is formed by lapping and adhering inner edges; the cross section of the steel strip has a shape with two hooked sides; an upper stapler and a lower stapler for limiting the steel strip are arranged in the clamping groove; the periphery of the steel strip which is wound to be spiral is welded with netlike steel bars which consist of axial parallel steel bars and oblique crossed steel bars; and the outer wall of the tube is a coating layer which covers the single hollow plastic plate strip, the netlike steel bars and the periphery of steel strip. The connecting effect of the netlike steel bars makes that all strip rings of the spiral steel strip are fixedly connected into a cylindrical integral body, soft connection is changed into rigid connection, and the tube material has high integrity, so that the tensile strength, the bending strength and the impact strength of the tube material are improved, a cracking phenomenon is avoided, and the service life is long and can reach over 50 years.
Description
Technical field
The steel plastic composite structure wall tubing that a kind of plumbing field is used.
Background technique
Occur a kind of single hollow in recent years and strengthen profiled strip steel plastic composite structure wall waste pipe, its inner tube wall is reeled by single hollow plastic strip and is formed.The inside rim of at first single hollow plastic strip being stretched out toward both sides respectively in winding process is bonded together behind the overlap joint mutually again, in the draw-in groove that inside rim overlap joint back constitutes, reel to embed then and strengthen profiled strip, the steel band shape of cross section is that both sides are hook-type, covers one deck plastic layer at last on single hollow plastic strip and steel band periphery.Be rigidly connected owing to be wound into not have between the spiral steel band zone circle, therefore exist tensile strength low, the defective of bend resistance ability, excessive tensile force or folding s tress make the body cracking easily.
Summary of the invention
The purpose of this utility model provides the single hollow profile steel band of a kind of netted steel bar enhancement mode steel-plastic composite pipe, accomplishes the tensile strength height, and counter-bending ability is strong.
Inner tube wall of the present utility model is through coiling, viscose glue and single hollow plastic strip that the inside rim overlap joint that will stretch out to both sides respectively is bonded together, in inside rim is taken the draw-in groove that glues back formation, reel to embed the enhancing profiled strip is arranged, the steel band shape of cross section is that both sides are hook-type, the upper and lower protruding kiss that pair spacing usefulness of steel band is arranged in the draw-in groove, be wound into and be welded with the netted steel bar that is made of parallel to an axis steel bar and diagonal cross steel bar on the spiral steel band periphery, the pipe outer wall is the plastic layer that covers on single hollow plastic strip, netted steel bar and the steel band periphery.
The production technology of this product is as follows: single hollow plastic strip is reeled on mould, and coiling limit, limit behind the overlap joint is bonded together the inside rim that single hollow plastic plate stretches out toward both sides respectively mutually again.With it simultaneously, enhancing profiled strip coiling is embedded inside rim to be taken in the draw-in groove of sticking back formation, then along the diagonal cross steel bar that is wound into spiral steel band periphery welding parallel to an axis steel bar and intersects in twos, weld with the spot welding mode steel bar and each steel band zone circle intersection, covers one deck plastic layer at last on single hollow plastic strip, netted steel bar and steel band periphery.
Compared with the prior art, characteristics of the present utility model are that the interconnect function of netted steel bar makes all zone circles of steel band of spirality be fixed into cylindrical shape integral body, deliquescing is connected to and is rigidly connected, integrity is strong, thereby improve stretch-proof, bend resistance and the impact resistance intensity of tubing, stopped cracking phenomena, long service life can reach more than 50 years.In addition, the protruding kiss of draw-in groove location is arranged when embedding owing to steel band, therefore improved speed of production and yield rate.
