Abstract

A single-size sand for playgrounds is provided to prevent the propagation of bacteria, inhibit a ramming phenomenon and an adhesion to clothes or skins, be free of chemical odor, and be superior in drainage and air permeability. A single-size sand for playgrounds is spread on a playground and has a narrow particle size distribution of 2.36-4.75 mm. The single-size sand is fine aggregate obtained by passing sand through 8 to 4-mesh sieves and is not rammed down well. The single-size sand comprises no fine sand such as dust and prevents dust from flying away or getting in child's eye. The single-size sand is easily recycled through washing and sieving after long-term use.

Description

놀이터용 단입도 모래{A single size aggregate for a playground}A single size aggregate for a playground}

본 발명은 놀이터용 단입도 모래에 관한 것으로, 상세하게는 놀이터에 포설된 모래가 2.36~4.75mm의 범위로 된 단입도 모래로 함으로써, 종래의 5mm 이하의 먼지를 포함한 광범위한 입도를 가진 모래가 포설되거나 폐타이어칩을 이용한 고무매트가 포설된 놀이터에 비하여 다져짐이 없고, 먼지의 날림이나 화학냄새가 없으며, 비산이 될만한 잔 입자가 없어 어린이들의 눈에 흙먼지가 들어가는 것이 방지되고, 옷 등에 흙먼지가 묻는 것이 방지되며, 배수성과 통기성이 좋아 세균 번식이 없는 놀이터용 단입도 모래에 관한 것이다.The present invention relates to a single-grained sand for playgrounds, and in particular, by the single-grained sand having a range of 2.36 to 4.75 mm of sand installed in the playground, sand having a wide particle size including dust of 5 mm or less in the prior art is installed. Compared to the playground where rubber mats using waste tire chips are installed, there is no compaction, no dust blowing or chemical smell, no scattering particles to prevent dust from entering the eyes of children, and no dust on clothes, etc. It is prevented from burying, and it is also related to sand for playgrounds that have good drainage and breathability and are free of bacterial growth.

학교, 공원, 아파트 등에 어린이들의 놀이를 위한 각종 놀이도구가 설치된 놀이터는 어린이들의 안전 사고를 예방하기 위하여 모래 또는 쿠션 있는 바닥재가 사용된다.Playgrounds with various play equipment for children's play in schools, parks, apartments, etc. are used with sand or cushioned flooring to prevent children from accidents.

모래의 경우 특정 입도가 한정되지 않고, 세골재 정도의 입도를 가지는 것으로, 상기 세골재는 흙먼지 등의 아주 작은 입도를 포함하는 5mm 이하의 수준이다.In the case of sand is not limited to a specific particle size, and having a particle size of fine aggregate, the fine aggregate is 5mm or less level including a very small particle size, such as dirt.

이와 같이 세골재가 놀이터의 바닥에 포설되어 사용되는 경우는, 미세한 흙 먼지가 바람에 날리는 문제가 있고, 세골재라도 넓은 입도의 분포를 가지기 때문에 바닥이 다져져 완충작용을 하지 못하는 문제점이 있으며, 미세한 입도가 눈에 들어가 안과질환을 유발시키기도 하고, 신체의 피부나 옷 등에 잘 묻어나는 문제가 있다.As such, when the aggregate is used on the floor of the playground, there is a problem that fine soil dust is blown in the wind, and even fine aggregate has a problem of having a wide particle size distribution, thus preventing the buffering action due to the compaction of the particle. Eyes can cause eye diseases, and the body's skin, clothing, etc. have a problem.

그리고, 폐타이어 등을 잘게 쪼개어 만든 블록을 바닥재로 사용하는 경우는 쿠션감은 있으나 화학약품에 의한 유독한 냄새가 건강이 좋지 않고, 모래 놀이와 같은 것을 할 수 없는 단순한 바닥재의 이용만이 가능하다.In the case of using blocks made of finely divided waste tires as flooring materials, there is a cushioning feeling, but toxic smells due to chemicals are poor in health, and only simple flooring materials which cannot play such as sand play are possible.

본 발명의 목적은 놀이터의 모래를 2.36~4.75mm의 범위만으로된 단입도로 함으로써, 다져짐이 방지되고, 흙먼지의 날림이 없으며, 옷이나 피부에 묻지 않고, 눈에 들어가지 않으며, 손으로 모래 놀이를 할 경우에도 손에 흙먼지가 잘 묻지 않도록 하고, 배수와 통기성을 높여 세균의 서식이나 번식을 못하도록 하여 청결하고 위생적인 놀이터용 단입도 모래를 제공함에 있다.The object of the present invention is to make the sand of the playground into a single grain only in the range of 2.36 ~ 4.75mm, to prevent compaction, no dust dust blowing, do not get on the clothes or skin, do not get into the eyes, sand by hand Even when playing, it prevents dirt and dirt from getting on your hands, and increases the drainage and breathability to prevent the breeding and breeding of germs.

본 발명은 놀이터에 포설되는 모래로서, 8메시(2.36mm)~4메시(4.75mm)의 단입도만으로 구성됨을 특징한다.The present invention is characterized in that the sand is installed in the playground, consisting of only a single particle size of 8 mesh (2.36mm) ~ 4 mesh (4.75mm).

즉 본 발명에 의한 놀이터용 모래는 통상의 세골재가 0~5mm 의 넓은 입도 분포를 가지고, 먼지와 같은 작은 입도와 5mm의 큰 입도가 함께 혼합된 것임에 비하 여, 본 발명은 특정 입도인 2.36~4.75mm임을 특징으로 한다.That is, the sand for playgrounds according to the present invention has a wide particle size distribution of 0 to 5 mm in general, and is mixed with a small particle such as dust and a large particle size of 5 mm. 4.75mm.

본 발명에 있어서의 단입도는 메쉬(mesh)별로 체가름되어 근소한 오차만을 가진 단입도를 말한다. 즉, 상기의 '근소한 오차만을 가진 단입도'는 종래와 같은 0~5mm의 전체의 넓은 입도 분포를 가진 것이 아니라, 1mm, 2mm, 3mm, 4mm, 5mm 등 반드시 단입도만을 선별하여 사용됨을 의미하고, 2.36~4.75mm와 같이 단입도라고 할 수 있는 메쉬별 근소한 오차만을 가진 것만을 체가름하여 선별된 세골재를 의미한다.The single particle size in the present invention refers to a single particle size having only a slight error by sieving each mesh. That is, the 'single particle size with only a small error' does not have a wide particle size distribution of 0-5 mm as in the prior art, but means that only a single particle size, such as 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, is selected and used. , Fine granules selected by sifting only those with a slight error for each mesh, which can be called single grain size, such as 2.36 ~ 4.75mm.

이와 같이 본 발명이 2.36~4.75mm의 입도로 한정함은 다짐이 없고, 바람에 흩날리지 않으며, 손으로 얼굴에 던졌을 때 눈에 들어가지 않으며, 피부나 옷에 먼지등이 잘 묻지 않고, 배수성과 통기성을 향상시켜 세균의 서식을 방지할 수 있는 위생적인 입도이기 때문이다.As such, the present invention is limited to a particle size of 2.36-4.75 mm without determination, does not fly in the wind, does not enter the eyes when thrown into the face by hand, does not get dirt on the skin or clothes well, This is because it is a hygienic particle size that improves breathability and prevents the growth of bacteria.

이와 같은 단입도의 모래가 어린이 놀이터 등에 포설되어 사용되는 경우, 단입도이기 때문에 다짐 현상이 없다. 따라서 놀이터에서 장난을 하는 어린이들이 넘어지더라도 쿠션의 역할을 유지하기 때문에 다치는 경향이 없게 된다.When the sand of such a single grain size is installed and used in a children's playground or the like, there is no compaction phenomenon because of the grain size. Therefore, children who play on the playground will not be injured because they maintain the role of cushion even if they fall.

그리고 모래를 던지는 등 다양한 놀이의 경우에, 적절한 단입도로 구성된 모래이기 때문에 눈에 들어가는 경우가 없다. 즉, 미세한 입도의 모래는 눈을 깜박이더라도 눈썹의 사이로 들어가게 되지만, 본 발명의 입도는 2.36~4.75mm의 단입도로만 구성되어 있어 눈썹을 깜박일 경우 눈으로 들어가는 것을 차단할 수 있다.In the case of a variety of games, such as throwing sand, sand does not get into the eyes because it is composed of appropriate single grains. In other words, the fine grain of sand enters between the eyebrows even if the eye blinks, but the particle size of the present invention is only composed of a single grain of 2.36 ~ 4.75mm to block entering the eye when the eyebrows blink.

그리고 바람이 불 경우에 종래의 경우는 미세한 입도의 모래가 날려 가게 되지만, 본 발명은 바람에 의해 비산되지 않는 적정입도로 되어 있어, 바람이 부는 날에도 놀이터에서의 활동이 가능하다.When the wind blows, the sand of a fine particle size is blown in the conventional case, but the present invention has an appropriate grain size that is not scattered by the wind, and the activity on the playground is possible even on a windy day.

뿐만 아니라 피부나 옷 등을 더럽히는 것은 아주 미세한 입도의 모래 의한 것이므로, 본 발명에 의한 단입도 모래의 경우는 놀이터에서 모래를 이용한 모래놀이 등의 다양한 신체 접촉의 활동에 의해서도 피부나 옷 등에 흙 때와 같은 더러움이 방지된다.In addition, since dirt of the skin or clothes is caused by very fine grained sand, the single grain sand according to the present invention may be soiled on the skin or clothing even by various physical contact activities such as sand play using sand in a playground. The same dirt is prevented.

이와 같이 본 발명은 2.36~4.75mm의 단일 입도를 가진 놀이터용 모래는 오래 사용하더라도 다짐이 없어 쿠션의 기능을 오래 유지하여 안전사고를 예방하게 되고, 미세 입도가 없어서 바람에 흩날리거나 모래를 던지더라도 눈에 들어 가는 일이 없으며, 피부나 옷을 더럽히는 흙 때의 발생이 방지된다. 그리고 단입도로 되어 공극을 잔입자가 메우는 것이 방지되어 통기성과 배수성이 향상되어, 세균의 서식이 없어 매우 위생적인 놀이터가 될 수 있다. 또한 오래 사용한 후에는 다시 세척과 채가름만으로 용이하게 재활용할 수 있게 된다.As described above, the present invention is a playground sand having a single particle size of 2.36 ~ 4.75mm, even if used for a long time to prevent the safety accident by maintaining the function of the cushion for a long time, even if it is scattered in the wind or throwing sand because there is no fine grain It does not get into your eyes and prevents dirt from soiling your skin or clothing. In addition, it is possible to become a single particle to prevent the filling of voids, thereby improving breathability and drainage, and there is no germ incubation, which can be a very hygienic playground. In addition, after long use, it can be easily recycled again by washing and coloring.
