Title: Agricultural reflective sheet forming tube
Inventor: KIM DE IK
IPC: B32B1/08
Filed: 2019-08-29
Granted: 2020-06-11
Abstract: The present invention relates to an agricultural reflective sheet having a tube formed therein. Among fruits, apples have the characteristics in which the peculiar red color of the fruit is expressed only when sunlight is irradiated, and thus the fruit surface on the ground side that is not directly exposed to sunlight is hardly colored. Accordingly, on each of both sides of the ground under fruity branches or between fruit trees, a reflective sheet integrally formed with a tube capable of filling water is laid in the longitudinal direction, and the tube is filled with water to use the load of the water so as to continuously fix the reflective sheet onto the ground. Therefore, the reflective sheet is prevented from being moved by wind, and sunlight is reflected from the bottom of a fruit without leaving the ground, so that sunlight can evenly reach all parts of the fruit. A conventional reflective sheet has problems in which: ground-fixing takes a lot of time and money; even when ground-fixing is performed by using a heavy object such as soil or stone in a discontinuous form, wind causes easy separation and reoperation is required; a separated reflective sheet causes environmental pollution; and safety accidents occur on a power line due to the separated reflective sheet. To solve the problems, the present invention provides an agricultural reflective sheet having a tube formed therein. According to the present invention, a tube that can be filled with water is formed on each of both sides of a reflective sheet, and thus the reflective sheet is stably fixed to the ground in a continuous form due to the weight of water, so that time and costs consumed for an operation of unfolding and removing the reflective sheet can be saved. In addition, environmental pollution caused by the reflective sheet torn and flown by wind can be prevented, and the occurrence of a fire due to a short circuit of a power line can be prevented. There is also an additional effect of preemptively preventing the inconvenience of residents caused by a power outage.

Abstract: 본 발명은 작업자가 건축물의 지붕 경사각도에 상관없이 발판이 수평인 상태에서 안전하게 작업을 할 수 있으면서, 작업자의 발판을 통한 보행 시 지붕에 전달되는 충격을 줄여주며, 지붕의 구조 변경없이 설치되는 지붕 보행용 안전계단에 관한 것으로써, 더욱 상세하게는, 지면을 향해 경사진 지붕에 상호 결합되어 연속적으로 설치된 마감재의 결합부에 설치되는 지붕 보행용 안전계단에 있어서, 한 쌍의 결합부의 길이 방향을 따라 각각 미리 정해진 간격으로 설치되는 다수의 고정부재와;, 한 쌍의 결합부 위로 각각 다수의 고정부재에 설치되는 한 쌍의 측면 고정판과;, 한 쌍의 측면 고정판의 사이에서 길이 방향을 따라 미리 정해진 간격으로 계단 형태로 설치되는 다수의 발판을 포함하며, 고정부재는 결합부가 끼워지는 끼움홈이 각각 외면에 형성되고, 체결부재로 체결되는 체결구멍이 각각 외면에 형성된 한 쌍의 고정브라켓과;, 한 쌍의 고정브라켓의 체결구멍과 체결부재로 체결되는 제1체결구멍이 외면에 형성되고, 측면 고정판에 체결부재로 체결되는 제2체결구멍이 외면에 형성된 고정판을 포함하고, 측면 고정판은 다수의 고정판의 제2체결구멍과 체결부재로 체결되는 체결구멍이 길이 방향을 따라 미리 정해진 간격으로 다수로 외면에 형성되고, 지면과 지붕 사이의 경사각도에 대응하는 형태로 형성되는 제1체결판과;, 제1체결판의 상부에서 돌출 형성되며, 다수의 발판에 체결부재로 체결되는 제1체결구멍이 길이 방향을 따라 미리 정해진 간격으로 다수로 외면에 형성되는 제2체결판을 포함하며, 발판의 양쪽 측면에는 한 쌍의 제2체결판의 제1체결구멍과 체결부재로 체결되는 체결구멍이 형성되는 것을 특징으로 하는 지붕의 구조 변경없이 설치되는 지붕 보행용 안전계단에 관한 것이다.
