Description
본 발명은 합성수지제로 구성된 나선관에 관한 것으로서 특히 경량이면서 외토압 보강이 증대되는 제품을 제공하는 고강도 구조용 나선관에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spiral tube made of synthetic resin, and more particularly, to a high strength structural spiral tube providing a product having increased weight and external pressure reinforcement.
일반적으로 지하에 매설하여 하수로 및 오폐수로 등으로 사용되는 배수관의 외토압 보강을 위하여 종래의 나선관의 요부인 중공부의 구조가 지하에 매몰하여 사용 도중 외토압 하중을 받으면 양측 벽면이 외측으로 휘어지면서 나선관의 원주 방향 단면이 타원형으로 변형될 뿐만 아니라 매설후 외부에서 가해지는 압력으로 나선권회로 형성된 길이 방향으로 보강대의 사이사이에 형성된 접착대의 요홈부위가 외토압에 쉽게 파손되며 배수관의 두께를 두껍게 할 경우에는 중량이 무거워지고 생산 원가가 상승하는 문제가 제기 되었다.In general, in order to reinforce the external pressure of the drain pipe used in sewers and wastewater channels by buried underground, the hollow part, which is the main part of the conventional spiral pipe, is buried underground, and when both sides of the wall are subjected to external pressure during use, the walls of both sides bend outwards. In addition, the circumferential cross section of the spiral pipe is deformed into an oval shape, and the grooves of the bond between the reinforcing bars in the longitudinal direction formed by the spiral winding by the pressure applied from the outside after being buried are easily damaged by the external soil pressure. Thickening raises the problem of heavy weight and rising production cost.
따라서 상기 문제점을 보강하기 위하여 보강대 사이의 접착대의 요홈부 위에 별도의 다이스에서 압출되어 절곡시켜준 파형보강대를 접착대에 일체로 융착시켜 주면서 외측덮개로 고정된 제품을 제공하였으나 이는 성형공정에서 냉각수로 냉각을 하면서 제조되므로 융착력이 낮아서 실용성에는 한계가 있었다.Therefore, in order to reinforce the above problem, the corrugated reinforcing bar extruded from a separate die and bent on the recess of the bond between the reinforcing bars was integrally fused to the bonding table, but the product was fixed with the outer cover. Since it is manufactured while cooling, there is a limit in practicality because of low adhesion.
본 발명은 종래의 나선관에서 보강대 사이 사이의 접착대 부위의 파형 보강대 구조를 개선하여 가벼우면서도 외토압에 대한 내구력이 증대되도록 하는데 그 기술적 과제가 있다.The present invention has a technical problem to improve the durability of the external light pressure and light weight by improving the structure of the corrugated reinforcement portion of the adhesive zone between the reinforcement in the conventional spiral tube.
도1는 본 발명의 요부인 경사파형지지대의 절곡장치로서 다이스에서 압출된 압출튜브에 일체된 보강튜브를 베벨기어로 절곡시켜 성형기의 성형롤러에서 나선권회로 일체화하되 별도로 압출된 외측덮개로 외접시켜 주는 제조장치를 일부 절개시켜 도시된 사시도1 is a bending device for the inclined wave support which is the main part of the present invention, the reinforcing tube integral with the extruded tube extruded from the die is bent with a bevel gear to integrate the spiral winding in the forming roller of the molding machine, but externally with the outer cover extruded separately.

본 발명을 도면에 의거 상세히 설명하면Referring to the present invention in detail based on the drawings
도1에 도시된 바와 같이 압출기(3)의 다이스(2)에서 압출되는 압출튜브(4)의접착대(24) 일측을 절곡부(18)로 절곡하여 보강튜브(5)를 성형기(1)에 지지틀(8)로 고정한 베벨기어(21)(21')로 압출속도에 맞추어 베벨기어의 회전 속도를 조정하여서 보강튜브(5)를 절곡시켜서 성형기의 성형롤러(20) 회전으로 나선권회로 접착대(24)에 일체로 나선 방향으로 돌출(11")되고 외측부위로 좌우방향으로 돌출대를 교호상으로 형성하는 경사파형보강대(11')를 보강대(14) 높이에 맞추어 주되 외측덮개(19)로 경사파형보강대(11')와 보강대(14)의 상측면에 일체로 외접시켜 제공되는 발명이다.As shown in FIG. 1, one side of the adhesive table 24 of the extruded tube 4 extruded from the die 2 of the extruder 3 is bent into the bent portion 18 to form the reinforcement tube 5. The bevel gears 21 and 21 'secured by the support frame 8 to the bend gears adjust the rotational speed of the bevel gears in accordance with the extrusion speed so that the reinforcement tube 5 is bent to rotate the forming roller 20 of the molding machine. An inclined corrugated reinforcing bar 11 'which protrudes 11 "in a spiral direction integrally with the bonding table 24 and forms a protruding bar alternately in the left and right direction at the outer part is fitted to the height of the reinforcing bar 14, but the outer cover 19 The invention is provided by integrally externally externally inclined wave reinforcement (11 ') and the upper side of the reinforcement (14).
일반적으로 도2에 도시한 종래의 접착대(24)에 파형보강대(11)를 융착대(5")로 융착시켜 준 제품은 좌우 돌출폭은 넓으나 융착대(5") 부위의 융착력이 미흡하므로 제품의 견고성이 낮은 현실이다.In general, a product in which the corrugated reinforcement band 11 is fused with a fusion band 5 "to the conventional adhesive bar 24 shown in FIG. 2 has a wide left and right protrusion width but the fusion force of the fusion band 5" is high. As it is insufficient, the robustness of the product is low.
고로 본 발명의 제품은 접착대(24)에서 돌출된 보강튜브(5)를 성형공정에서 베벨기어(21)(21')로 절곡시켜 성형되는 구조로서 하측부위는 접착대(24)에 일체로 돌출되고 상측방향부위는 좌우방향으로 돌출된 경사파형구조의 제공으로 비록 종래의 파형보강대와 비교하여 하측부위의 좌우 돌출폭은 작으나 접착대(24)와의 돌출로 일체화되므로 전체적인 제품의 견고성이 대폭 보강되는 것이다.Therefore, the product of the present invention is a structure formed by bending the reinforcing tube 5 protruding from the bonding table 24 into the bevel gears 21 and 21 'in the forming process. The lower part is integrally formed with the bonding table 24. Protrusion and upper part protrude in the right and left direction, and the inclined wave structure is provided, although the left and right protruding width of the lower part is smaller than that of the conventional corrugated reinforcement bar, but it is integrated with the protruding with the bonding table 24, thereby greatly strengthening the overall product robustness. Will be.
상기 설명한 바와같이 본 발명은 나선관의 접착대 부위에서 파형보강대의 구조를 개선하여서 외토압에 대하여 강도가 증대되는 효과가 있는 것이다.As described above, the present invention has the effect of increasing the strength against external pressure by improving the structure of the corrugated reinforcement at the bonding zone of the spiral tube.
특히, 본 발명은 합성수지제로된 나선관에 있어 파형보강대의 접착대에서 돌출시켜 형성된 경사 파형보강대와의 구조로 개선하므로서 고강도의 제품을 제공할수 있는 유익한 발명인 것이다.In particular, the present invention is an advantageous invention that can provide a high-strength product by improving the structure of the inclined corrugated reinforcing bar formed by protruding from the adhesive band of the corrugated reinforcement in the spiral tube made of synthetic resin.
