Description

Reinforcement device for structural spiral pipes {.}

The present invention relates to a reinforcement device for structural reinforcement spiral pipes widely used as waste water pipes, sewer pipes, drainage pipes.

The reinforcement device of the conventional reinforcement spiral pipe has a heavy use weight compared to the external pressure reinforcement effect, which makes it difficult to be practically used as a problem for economic efficiency. According to 1996-22172, 10-2000-824, the conventional cross section In the actual manufacturing process, it is difficult to construct a fusion band to integrate the reinforcing belt 15 in the middle portion of both side walls to external pressure reinforcement to the hollow portion 12, and economical production is difficult. It is used to extrude the belt integrally on one side of its manufacturing process is a difficult reality.

The present invention is a product mainly intended for economic application in the medium-large (Ø600m / m or more) product of the spiral tube to form a fusion rib 14, 14 'on both side wall surface 13 of the hollow sphere 12, but separate melting The reinforcing belt 23 is integrally formed with the fusion ribs 14 and 14 'by the extrusion furnace to form the reinforcing bar 15 and the V-shaped reinforcing bar 18 and the fusion bar 16 to provide external pressure reinforcement structurally.

The present invention provides a reinforcing rib 14 for economically integrating the reinforcing bar 15 in the middle portion of both side wall surfaces 13 of the hollow portion 12 in the groove portion and the hollow portion formed in the spiral winding direction in the conventional spiral tube. While forming the middle parts of the reinforcing bar 15 while fusion integrally bonded to both sides of the reinforcing rib 14, the PE raw material extruded from a separate die not shown in a separate drawing integrally to the reinforcing rib (14) It is bent to provide a product configured by fixing the V-shaped support 18 to the fixing table 20 by the fusion table 26, as an example of the reinforcing rib as shown in Figures 4, 5 (a), 6 The product of the present invention is provided even if the upper side of the side wall surface 13 is provided, and the reinforcement product of the present invention is provided even when the reinforcing bar 15 having a straight cross section is integrated instead of the V-shaped support 18. This is provided. As shown in Fig. 5 (b), hook ribs 34 are formed on both side walls 13 so as to reinforce the bonding force instead of the ribs 14, but both sides of the support 15 are assembled into the assembly table 35. It is formed to reinforce the binding force to reinforce the warning of the present invention.

At this time, as an application thereof, as shown in FIGS. 7, 8, and 9, the reinforcing outer wall 24 formed by integrating the molten reinforcing belt 23 from the upper layer surface 16 of the hollow part 12 used in the conventional product is integrated. In the conventional reinforcement spiral pipe forming the corrugated reinforcing outer wall 25, the reinforcing ribs 14 are formed on both side walls 13 simultaneously with the extrusion of the hollow portion 12, and the support 15 or the V-shaped support 18 is formed. And the fusion zone 26 is provided to provide robustness and external pressure reinforcement.

As shown in FIGS. 10, 11, and 12, the spiral pipe 11 is formed of the spiral winding circuit hollow portion 12 and the fixing base 20 in the spiral pipe 11 to form both side wall surfaces 13 of the hollow portion 12. Fusion ribs 14 and 14 'are respectively formed on the upper side 16 and the middle portion of the fusion splicing ribs 14 of the PE molten reinforcing belt 23 extruded from an auxiliary die not shown in the drawing. It is a product that constitutes reinforcing bar 15 or V-shaped support 17 by integrating both sides to ') .At this time, if the size of spiral tube is larger than Ø800m / m, a large number of fusion ribs 14 (14) ') And the support (15, 15') is composed of a plurality of integral to reinforce the external pressure and robustness.

As Example 1 of the present invention, as shown in Fig. 13 (a), 14 and 15, the product of the present invention is further reinforced with external pressure reinforcement, and the size of the spiral tube is mainly applied to super-large (Ø1200m / m or more) products. As a product for the purpose, the hollow tube 12 which lowers the height of the hollow portion 12 having the same thickness to about half is integrated in the spiral tube 20, and both sides of the auxiliary hollow sphere 12 'having the height of about half. A fusion rib 14 is formed on the lower portion of the wall surface 13 to helically wound the upper portion 16 of the hollow portion 12 in an integral manner, and the molten reinforcement belt 23 extruded from a die not shown in the drawing is fused. As a reinforcement device for reinforcing spiral tubes provided integrally with the ribs 14, the reinforcing outer wall 24 and the corrugated reinforcing outer wall 25 are integrally formed on the upper side of the auxiliary hollow tool 12 ', and thus, the external pressure is more economical. Is provided and instead of ribs 14 as shown in Figure 13 (b). To further reinforce the strength and enhance the rigidity of the reinforcement given by the coupling force to form the both side portions of the support 15 to form a hook rib (34) on each side wall 13 to the assembly for 35 invention. As an embodiment thereof, as shown in Figs. 16, 17 and 18, the auxiliary hollow sphere 12 'is further laminated to the reinforcement device 15 and the V-shaped support 18 and the fusion splicer with the reinforcement device of the present invention in a three-layer structure or more. The invention provides (26).

In the second embodiment of the present invention, as shown in FIGS. 19 and 20, the upper surface 16 is bent in the hollow section of the hollow parts 12 and 12 'to form the V-shaped support 28 and the fusion table 26. The product that provides the corrugated support 26 and the fusion point 22 or the V-shaped support outer wall 27 and the fusion support 26 is an invention that reconstructs the competitiveness in external pressure reinforcement and economical product provision.

The present invention provides a defect in the reinforcing spiral tube, and provides external pressure and rigidity reinforcement, in particular, forming a fusion rib 14 on both side wall 13 of the hollow portion 12, but both sides of the molten reinforcement belt (23) The reinforcing support 15, V-shaped support 18, or corrugated support 19 or hanger rib 34 or assembly stand 35 according to the characteristics of the product, respectively. By dividing the height into 2-3 equal parts, the auxiliary hollow parts 12 'are overlapped, and the reinforcing bar 15 is formed in 2-3 layers, so that the molten reinforcement is applied to the upper side 16 of the hollow part 12 as in the prior art. The present invention is to provide a high economic product compared to the conventional reinforcing spiral tube provided by overlapping the belt 14 with each other.
