Abstract
The utility model relates to a reticular steel bar reinforced type double hollow abnormal steel belt steel-plastic composite pipe material. The inner wall of a pipe is made of double hollow plastic plate belts which glue outer cavity walls together through winding and gluing, reinforced abnormal steel belts are wound and embedded in clamp grooves formed in the middles of the double hollow plastic plate belts, the cross section of the steel belts is in a shape that both sides are in a hook shape, an upper convex lip and a lower convex lip realizing a position limiting effect on the steel belts are arranged in the clamp grooves of the double hollow plastic plate belts, reticular steel bars formed by axial parallel steel bars and inclined crossed steel bars are welded on the periphery of the steel belts wounded into the spiral shape, the outer wall of the pipe is a plastic cement layer covered on the peripheries of the double hollow plastic plate belts, the reticular steel bars and the steel belts. Through the connecting effect of the reticular steel bars, all belt rings of the spiral steel belts are fixedly connected into a cylindrical whole body, the flexible connection is changed into rigid connection, and the integrality is high, so the tensile strength, the bending resistance strength and the collision resistance strength of the pipe material are improved, the cracking phenomenon is avoided, and the service life is long and can reach more than 50 years.
Description
Technical field
The steel plastic composite structure wall tubing that a kind of plumbing field is used.
Background technique
201020198089.4 number utility model patent has proposed a kind of " two hollow double-walled sealing steel band enhanced type steels are moulded the structural walls waste pipe ", its inner tube wall is the two hollow plastic strips that bond together through coiling, viscose glue and with outer chamber wall, reeling to embed in the draw-in groove of two hollow plastic strips middle part has closed enhancing profiled strip, and the pipe outer wall is the plastic layer that covers on two hollow plastic strips and the steel band periphery.It is fast that this product has speed of production, and the yield rate height, in light weight, ring stiffness is big, steel are enclosed in the plastics strip, not corrodible characteristics.Owing to be wound into not to have between the spiral steel band zone circle and be rigidly connected, have therefore that tensile strength is low, the defective of bend resistance ability, excessive tensile force or folding s tress make body ftracture easily.
Summary of the invention
The purpose of this utility model provides the two hollow profile steel band steel-plastic composite pipes of a kind of netted steel bar enhancement mode, accomplishes the tensile strength height, and counter-bending ability is strong.
Inner tube wall of the present utility model is through reeling, viscose glue and two hollow plastic strips that outer chamber wall is bonded together, improvements are to reel to embed in the draw-in groove of two hollow plastic strips middle part 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 two hollow plastic strip draw-in grooves, 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 two hollow plastic strips, netted steel bar and the steel band periphery.
The production technology of this product is as follows: two hollow plastic strips are reeled on mould, and coiling limit, limit viscose glue bonds together the outer chamber wall of two hollow plastic strips.With it simultaneously, to strengthen the profiled strip coiling embeds in the draw-in groove of two hollow plastic strips middle part, 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, lighting up with the spot welding mode and connect in steel bar and each steel band zone circle intersection, covers one deck plastic layer at last on two hollow plastic strips, netted steel bar and steel band periphery.
Compared with the prior art, characteristics of the present utility model are that all zone circles of the interconnect function of the netted steel bar steel band that makes spirality are 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.

Embodiment
As shown in the figure, inner tube wall of the present utility model is through reeling, viscose glue and two hollow plastic strips 1 that outer chamber wall 10 is bonded together, difference is to reel in two hollow plastic strip 1 middle part draw-in grooves to embed the profiled strip 2 of enhancing is arranged, steel band 2 shape of cross sections are that both sides are hook-type, have in two hollow plastic strip 1 draw-in grooves pair steel band 2 spacing usefulness on, following protruding kiss 11,12, be wound on spiral steel band 2 peripheries and be welded with the netted steel bar that is made of parallel to an axis steel bar 4 and diagonal cross steel bar 5, the pipe outer wall is for covering two hollow plastic strips 1, plastic layer 3 on netted steel bar and steel band 2 peripheries.
