Abstract

본 발명은 보강용 플라스틱 구조물의 제조방법으로 강도나 인장력을 배가(倍加)시킨 플라스틱 구조물을 생성하는 것이다.The present invention is to produce a plastic structure doubled in strength or tensile force by the method of manufacturing a plastic structure for reinforcement.

종래의 보강용 플라스틱 구조물은 종열이나 횡열 어느 한쪽 방향으로만 연신하여 생산하였다.Conventional plastic structures for reinforcement have been produced by stretching only in either longitudinal or transverse rows.

이와 같이 일방향으로만 연신이 된 플라스틱 구조물은 연신이 일어나지 않은 방향의 열은 강도가 약하여 쪼개지거나 부러지는 등의 결함이 있어 시공후 하자가 많았으나 대안이 없었다.As described above, the plastic structure stretched in only one direction has many defects such as cracking or breaking due to weak strength of the heat in the non-stretching direction, but there are no alternatives.

따라서 본 발명은 플라스틱 구조물을 연신시킬 때 여러방향 즉 사방으로 동시 연신되게 하여 종열과 횡열 모두를 균등한 강도 및 인장력을 지닌 보강용 플라스틱 구조물을 생성하도록 한 것이다.Therefore, the present invention is to draw a plastic structure for reinforcement having an equal strength and tensile strength in both longitudinal and transverse rows by simultaneously stretching in multiple directions, i.e., when stretching the plastic structure.

보강용 플라스틱 구조물 제조방법Manufacturing method of plastic structure for reinforcement

It is stretched laterally to increase strength and tensile strength, which is used for civil engineering works or grain bags. Particularly, soil, sand, mud, etc. supported by plastic structures flow or flooded.
Figure kpo00003
The present invention relates to a method of manufacturing a plastic structure that prevents collapse.

일반적으로 플라스틱 판재를 제조할 때는 압출에 의하여 제조되므로 재료가 갖는 융점에 따라 분자연결고리가 압출되는 즉 힘이 주어지는 방향으로 꼬리를 물고 붙는 특성이 강해 압출되는 방향인 종열상으로는 강한 연결력을 갖으나 횡열은 구조적으로 약한 접합 구조를 갖게 된다. 이러한 플라스틱 압출 판재 구조상 1차종열연신은 강한 인장력이 증가되나 2차 횡열연신은 연신 자체가 불가능하였다.In general, the plastic sheet is manufactured by extrusion, so the molecular link ring is extruded according to the melting point of the material. The transverse rows will have a structurally weak junction structure. Due to the structure of the plastic extruded sheet, the primary longitudinal stretching increased the strong tensile force, but the secondary transverse stretching was impossible.

종래의 플라스틱 판재의 연신방법은 주로 먼저 구멍을 뚫은 후 플라스틱 판재를 연신하므로 한쪽이 연신되면 플라스틱 특성상 남은 한쪽은 연신되지 않아 사용 또는 시공후 찢어지거나 부러지는 폐단이 발생하였다.Conventional stretching method of the plastic sheet material is mainly punched first and then stretched the plastic sheet, so when one side is stretched, the remaining one is not drawn due to the plastic properties, resulting in tearing or breaking after use or construction.

이러한 현상은 플라스틱재로 특성상 압출판재를 제조할 때 압출방향으로 분자가 접합 배열하여 종열은 강하나 횡열은 약하게 되어 있기 때문이다.This phenomenon is because, when manufacturing the extruded sheet material due to the nature of the plastic material, the molecules are bonded and arranged in the extrusion direction so that the longitudinal column is strong but the transverse row is weak.

이 때문에 연결판재료로 제조되는 종이

철판 등에서도 종열은 강하게 접속되어 강한 인장력이 있으나 횡열은 쉽게 찢어지거나 파손되는 이치와 동일하다.Because of this, paper made of connecting plate material

Even in iron plates, the vertical columns are strongly connected and have strong tensile force, but the horizontal rows are the same as those easily torn or broken.

그래서 본 발명은 플라스틱으로 압출

이하, 본 발명의 제조공정을 첨부된 도면에 의거하여 상세히 설명한다.Hereinafter, the manufacturing process of the present invention will be described in detail with reference to the accompanying drawings.

본 발명은 플라스틱 판재(10)를 사방이 고르고 균일하게 즉 종열과 횡열의 어느 방향으로도 한 번에 고루 연신할 수 있게 한 방법이다.The present invention is a method in which the plastic sheet 10 can be stretched evenly and evenly, that is, evenly in any direction of vertical and horizontal rows at once.

플라스틱 판재(10)의 분자연결고리를 물리적 방법으로 종열과 횡열을 동시 또한 원방형으로 이동 변환시켜 줌으로서 보다 강한 보강재를 생산 활용할 수 있게 한 것이다.Molecular link of the plastic plate (10) by the physical method to convert the longitudinal and transverse rows in the same time and the square to make a stronger reinforcement can be produced and utilized.

플라스틱으로 압출

Figure kpo00006
성형되는 판재는 일정 두께와 넓이를 갖는 플라스틱 압출판재로서 구성 자체가 압출방향으로 분자연결고리가 많이 연결되어 배열된 상태이다.Extruded into plastic
Figure kpo00006
The plate member to be molded is a plastic extruded sheet member having a predetermined thickness and width, and the configuration itself is a state in which many molecular linking rings are arranged in the extrusion direction.

이때 성형된 압출판재는 물리적인 힘을 가할 때 분자연결고리가 힘을 가하는 방향으로 이동을 하게 되어 연신이 이루어지는 것이다.In this case, the molded extruded sheet material is stretched by moving in the direction in which the molecular linking force is applied when a physical force is applied.

그래서 완전연신이 종열이나 횡열상으로 되었을 때 분자연결고리도 종열이나 횡열상 어느 일방향으로 완전

Figure kpo00007
고정배치되어 다른 방향으로 2차 연신할 때에는 분자연결고리가 이동되지 아니하므로 찢어지거나 부러지는 현상이 생기는 것이다.Thus, when full stretching occurs in longitudinal or transverse rows, the molecular linkages are also complete in either longitudinal or transverse rows.
Figure kpo00007
When it is fixedly placed and drawn in the second direction in the other direction, the molecular link does not move and thus tears or breaks.

따라서 플라스틱 압출성형후 판재상태에서 한 번의 연신이 한방향으로 이루어지면 다른 방향은 연신할 수 없는 것이다.Therefore, if one drawing is made in one direction in the sheet state after plastic extrusion, the other direction cannot be drawn.

이와 같은 단점을 해결하고자 한 것이 본 발명으로서 플라스틱 판재(10)의 분자연결고리를 유도하기 위한 함몰부(22)와 돌출부(20)로 이루어진 한 쌍의 요철판(계란판형성) 즉, 상부요철판(14)과 맞물리는 하부요철판(16)을 구성하여 각각의 요철판(14)(16)사이에 플라스틱 판재(10)를 놓아서 요철판(14)(16)을 제2도에서와 같이 압착하게 되면 사방, 원방형으로 접합대역(12)이 한 번에 동시에 연신을 하게 된다. 이렇게 연신이 이루어지면 분자 연결고리가 사방으로 고르게 연결되어 일방이 아닌 사방이 강한 인장력과 강성을 지닌 보강용 플라스틱 판재가 된다.In order to solve the above disadvantages, the present invention provides a pair of uneven plates (egg plate formation), that is, a recess 22 and a protrusion 20 for inducing molecular linkages of the plastic sheet 10. The lower uneven plate 16 which meshes with the iron plate 14 is placed to place the plastic plate 10 between each of the uneven plate 14 and 16 so that the uneven plate 14 and 16 are as shown in FIG. When compressed, the junction band 12 is stretched in one direction at the same time in all directions and rectangles. When the stretching is performed, the molecular linkages are evenly connected in all directions to form a reinforcing plastic sheet having strong tensile strength and rigidity in all directions.

또한 수평한 판에 종열과 횡열로 형성된 각 돌출부(20)와 함몰부(22)에 있어서, 함몰부(22)의 둘레단이 돌출부(20)의 둘레면에 밀착되도록 하여 제2도와 같이 커팅부(24)를 이루게 한다. 이 구조에 의해 요철판(14)(16)을 끝까지 압착시키면 커팅부(24)가 돌출부(20)의 둘레 오주면에 밀착되어 결국 연신되던 플라스틱판재(10)가 절단되어 제4도와 같이 구멍을 뚫게 된다.In addition, in each of the protrusions 20 and the depressions 22 formed in vertical and horizontal rows on a horizontal plate, the periphery of the depressions 22 is in close contact with the circumferential surface of the protrusions 20 so as to be cut as shown in FIG. 2. (24). When the concave-convex plates 14 and 16 are pressed to the end by this structure, the cutting part 24 is brought into close contact with the circumferential circumferential surface of the protruding part 20 and the plastic plate material 10 which is eventually stretched is cut to cut holes as shown in FIG. Pierced.

이와 같은 구멍이 뚫리게 되면 구멍주변으로 분자고리가 원방으로 모여지고 동시에 연신이 이루어져 후차적으로 돌출형상이나 구멍을 형성할 수 있다.When such a hole is drilled, molecular rings are collected in a circumference around the hole, and at the same time, stretching can be performed to form a protrusion or hole afterwards.

또한 구멍의 주변이 요철을 이루고 있기에 토목공사시 흙과 잘 접할 수 있는 효과를 가져다준다.In addition, since the periphery of the hole forms an unevenness, it brings the effect of contacting well with soil during civil engineering work.

이와 같이 플라스틱판재(10)가 전체적으로 사방

Figure kpo00008
원방형으로 연신이 이루어져 판재가 종열과 횡열의 모든 방향으로 똑같은 인장력 및 강도를 갖게 하기 위한 것으로 본 발명의 가장 큰 특징으로는 연신이 필요한 요소의 중심부위를 물리적으로 동시에 눌러 플라스틱 분자연결고리를 모든 방향으로 균일하게 이동시키게 하는 점이다.In this way, the plastic sheeting material 10 is generally everywhere
Figure kpo00008
The drawing is made in a rectangular shape so that the sheet has the same tensile strength and strength in all directions of longitudinal and transverse rows. The biggest feature of the present invention is to simultaneously press the center of the element that needs to be stretched and simultaneously press all plastic molecular linkages. To make it move uniformly in the direction.

The plastic house cover, grain bag, etc., in particular, by manufacturing the structure of the plastic plate used as a ground reinforcement in all directions, there is an effect to obtain a strong and strong structure without the phenomenon that the structure is torn or broken in any one direction. In particular, when the plastic structure is used as ground reinforcement material, there is an effect of solving the construction defects such as ground subsidence due to running water.
