Abstract
The invention discloses a double-layer truss bicolor composite tube and belongs to the technical field of tubes. The double-layer truss bicolor composite tube comprises a tube body formed by winding and melting of a belt material side by side; the tube body comprises an inner wall, a hollow reinforcing rib spirally winding around the inner wall, and an outer wall connected between the axial adjacent reinforcing ribs; a strengthening inner rib is formed at the middle part in the hollow reinforcing rib, and auxiliary inner ribs are further respectively arranged on two side of the strengthening inner rib in the hollow reinforcing rib; a color layer is arranged on a tube internal surface of the tube body. The tube body formed by winding of the belt material is provided with a double-layer structure, namely a double-layer structure having inner and outer walls at a wave trough, and a stiffener is formed corresponding to the hollow reinforcing rib in the double-layer structure of the wave trough, so that the ring flexibility and the ring rigidity of the tube are improved, the tensile strength, the load resistance and the ductile failure resistance are also improved, and the structural stability, the flexibility, the ring rigidity stability, and the creep resistance of the tube are greatly improved.
Description
Technical field
The present invention relates to tubing technical field, in particular to a kind of double-deck double-colored multiple tube of truss.
Background technology
In many fields such as downcomer in city and drainage system, the use of the plastic pipe of band reinforcement gets more and more.The internal no pressure of drain pipe, for improving opposing extraneous pressure, the performance of impact, arranges multi-form reinforcement in tube wall periphery.Polyethylene winding structure wall pipe due to have good pipeclay jointly act on ring stiffness and be widely used in municipal administration blow-off line build in, it is to be wound around welding by multiple bands to form, the trough intensity between crest and crest outside pipe is the weakest, the surface in trough district is also stress rupture concentration zones simultaneously, when the most in transit or constructing on-site, trough district is easy to damage, bearing capacity is not enough, anti-weight bearing power and anti-ductile failure ability are relatively low, directly impact the serviceability of product.
Summary of the invention
It is an object of the invention to provide a kind of double-deck double-colored multiple tube of truss, to solve the problems referred to above.
For realizing the object of the invention, the technical scheme used is: the double-deck double-colored multiple tube of truss, including the tubing body by band wound side by side fusion molding, the outer wall that described tubing body includes inwall, the spiral surrounding hollow reinforced rib on inwall, is connected between axially adjacent hollow reinforced rib；Middle part in hollow reinforced rib is formed with enhancing internal-rib, and the both sides being positioned at enhancing internal-rib in hollow reinforced rib further respectively have auxiliary internal-rib；The pipe internal surface of described tubing body has color layers, i.e. the inner surface at inwall has color layers.
Further, described color layers is and band one extrusion molding.
Further, described enhancing internal-rib is positioned in the middle part of hollow reinforced rib, the welding of adjacent tapes side formed.
Further, two waists that the cross section of described hollow reinforced rib is trapezoidal and trapezoidal are bowed out arcuation.
Further, two auxiliary internal-ribs are strengthening the setting of internal-rib lateral symmetry.
The invention has the beneficial effects as follows:
1, the tubing body double-decker that band is wound, i.e. form the double-decker of inside and outside wall at trough, and the hollow reinforced rib in correspondence trough double-decker forms rib, improve ring flexibility and the ring stiffness of tubing, the peak structure that the auxiliary rib being connected between hollow reinforced rib and enhancing internal-rib is formed also enhances the strength and stiffness of crest hollow reinforced rib；
2, improve anti-weight bearing power, there is bigger specific surface area, expand the contact surface with soil, tube surfaces can be uniformly by external force, insert the native pressure jointly bearing Soil Surrounding with pipeline itself of the backfill in pipeline trough, forming pipeclay jointly to act on, it is possible to external loads decomposed rapidly and up hill and dale and be delivered in whole piece pipeline, reducing external loads to greatest extent affects the impact of pipeline self；
3, improve the ability of anti-ductile failure, double-deck trough drastically increases structural stability and pliable and tough, the stability of ring stiffness and the creep resistance of tubing, and toughness is greatly improved, and resistance to slow crack growth performance significantly improves；
4, improve hot strength, compared with conventional Hollow wall tube, hot strength improves 50%, and double-deck band bonding plane is generouser, adds the hot strength of adjacent tapes seam, so that tubing has more excellent anti-lateral pull.
Accompanying drawing explanation
Fig. 1 is the cross-sectional view of the double-colored multiple tube of double-deck truss that the present invention provides；
Fig. 2 is the sectional view of the band forming the double-colored multiple tube of bilayer truss of the present invention.
Detailed description of the invention
Below by specific embodiment and combine accompanying drawing the present invention is described in further detail.
Fig. 1 shows the double-colored multiple tube of double-deck truss that the present invention provides, including the tubing body 1 by band 7 wound side by side fusion molding, the outer wall 4 that tubing body 1 includes inwall 2, the spiral surrounding hollow reinforced rib 3 on inwall 2, is connected between axially adjacent hollow reinforced rib 3；Middle part in hollow reinforced rib 3 is positioned at the both sides of enhancing internal-rib 5 and further respectively has auxiliary internal-rib 9 in being formed with enhancing internal-rib 5, and hollow reinforced rib 3；The pipe internal surface of tubing body 1 has color layers 6, the i.e. inner surface at inwall 2 and has color layers 6.Auxiliary internal-rib 9 is connected laterally at the muscle inwall of hollow reinforced rib 3 and strengthens between internal-rib 5, can be one or more, the horizontally set of level or the horizontally set slightly tilted.Two auxiliary internal-ribs 9 are strengthening the setting of internal-rib 5 lateral symmetry, are that band is one-body molded.
Color layers 6 is to have color layers 6 with band 7 one extrusion molding, the i.e. lower surface of band 7, and color layers 6 can be blueness or other colors etc..By special extrusion die, by two extruders extrusion continuous print double-deck, double-colored have include the plastic shape band 7 of cavity.Band 7 includes two hollow boss 8, also includes inwall and the outer wall between two hollow boss 8, and two hollow boss 8 are positioned on inwall, and forms cavity between two hollow boss 8 and outer wall, inwall；Being provided with the rib being positioned at outer wall both sides between outer wall and inwall, hollow boss 8 is internal arranges its auxiliary internal-rib 9；The surface of inwall i.e. color layers 6.
Hollow reinforced rib 3 defines corrugated with the axial cross section of outer wall 4, and hollow reinforced rib 3 is crest, is trough at outer wall 4.Seeing Fig. 2, the band inner wall thickness at band trough is more than band outer wall thickness, and less than the band inner wall thickness at hollow boss.The cross section of hollow boss 8 is right angled triangle, and hypotenuse is connected with outer wall, and arc transition, and right-angle side is the face of weld between the side of band, i.e. adjacent tapes.
Strengthening internal-rib 5 and be positioned in the middle part of hollow reinforced rib 3, adjacent tapes 7 side welding formed, the hollow reinforced rib 3 with enhancing internal-rib 5 i.e. formed by molten plastic welding by the hollow boss 8 of adjacent tapes 7, the auxiliary internal-rib 9 in two hollow boss 8 is symmetrical.Two waists that the cross section of hollow reinforced rib 3 is trapezoidal and trapezoidal are bowed out arcuation, improve load and anti-load-carrying ability.
The foregoing is only the preferred embodiments of the present invention; it is not limited to the present invention, for a person skilled in the art, can have various modifications and variations in the spirit and principles in the present invention; the modification of these equivalents or replacement etc., within being all contained in protection scope of the present invention.
