Description
본 고안은 콘크리트 믹싱용 드럼의 과열을 방지하기 위한 살수장치가 부착된 레미콘(ready-mixed-concrete) 차량에 관한 것이다.The present invention relates to a ready-mixed-concrete vehicle equipped with a spraying device for preventing overheating of the drum for mixing concrete.
콘크리트는 구조물의 요구되는 역학적 강도에 부응하도록 그 배합비가 결정되어야 하며 수화반응에 의해 경시적(經時的)으로 경화되어 고체로 바뀌는 것이지만 경화(硬化) 이전에는 타설 작업에 필요한 소정의 유동성(workability)을 가져야 한다.The ratio of concrete should be determined to meet the required mechanical strength of the structure, and it will be cured over time by the hydration reaction and turn into a solid. However, before hardening, the required workability required for casting works Must have
콘크리트 타설량이 적은 경우에는 직접 건축물 구축현장에서 현장비빔과 현장타설을 할 수 있지만 일정 규모 이상의 대형 현장에서는 일반적으로 시멘트 공장에서 미리 벌크작업을 통해 콘크리트 재료의 투입 및/또는 비빔작업을 하고, 이를 레미콘 차량 등으로 작업현장까지 이송한 다음 콘크리트 펌프카 등과 같은 장비를 사용하여 필요한 곳에 부어넣는다.In the case of small amount of concrete pouring, it is possible to do bibimbal and site casting at the construction site of the building directly, but in a large site over a certain scale, the concrete material is input and / or bibimbed through bulk work in advance in the cement factory, and ready concrete Transfer it to a work site by car, etc., and then pour it where necessary using equipment such as concrete pump cars.
본 고안은 특히 레미콘 차량 특히 한 여름철과 같은 혹서기(酷暑期)에 사용하는 레미콘 차량을 위한 것으로서, 레미콘 차량의 믹싱드럼이 여름철 태양의 직사광선을 과도하게 받아 드럼 내부가 지나치게 과열됨으로써 수화반응(경화반응)이 지나치게 진행되어 투입된 재료의 유동성이 저하되는 문제(슬럼프값이 낮아지는 문제)를 해결하기 위한 것이다.The present invention is specifically for ready-mixed concrete vehicle used in the cold weather such as the ready-mixed concrete vehicle, especially in the summer, the hydration reaction (mixing reaction of the ready-mixed drum of the ready-mixed vehicle receives excessive sunlight in summer This is to solve the problem (problem of lowering slump) of fluidity of injected material due to excessive progress.
일반적으로 콘크리트의 유동성을 좌우하는 요소는 재료비(材料比), 특히 물시멘트비, A/E제와 같은 유동화제(공기연행제)의 유무, 알루미나 시멘트와 같은 시멘트의 종류, 비빔시간에 따른 수화반응의 진행정도 등이다. 한편 콘크리트는 유동성보다는 경화 이후의 역학적 강도가 더 중요하기 때문에 워커빌리티를 높이기 위해 시멘트의 종류, 재료비 등을 조절하는 데에는 제약이 있을 뿐만 아니라 콘크리트 재료투입 장소와 타설현장 간의 거리 등을 감안할 때 비빔시간을 임의로 조절하는 것도 쉽지 않다.In general, the factors that influence the fluidity of concrete are material cost, especially water cement ratio, the presence of a fluidizing agent (air-emulsion agent) such as A / E agent, the type of cement such as alumina cement, and the hydration reaction according to the beam time. The progress of On the other hand, since concrete has more important mechanical strength after hardening than fluidity, there are limitations in controlling cement type and material cost in order to increase workability, as well as considering the beam time when considering the distance between concrete input site and casting site. Arbitrary adjustment is not easy.
따라서 콘크리트 재료의 종류, 재료혼합비, 비빔시간 등이 요구되는 콘트리트 강도를 감안하여 소정의 범위로 제약이 있는 것을 전제로 할 경우 워커빌리티에 영향을 주는 요인을 가능한 한 효율적으로 제어할 필요가 있는데 본 고안은 바로 이러한 요청에 따라 혹서기인 여름철 레미콘 차량의 믹싱드럼이 태양열을 받아 과도하게 온도가 올라가는 것을 방지함으로써 그 내부에 투입된 재료의 적정한 수화반응을 유도하여 설계된 슬럼프(slump) 값을 유지할 수 있도록 하는 것을 기술사상의 요지로 하는 것이다.Therefore, in consideration of the concrete strength required for the type of concrete material, material mixing ratio, and beam length, etc., it is necessary to control factors affecting workability as efficiently as possible, provided that there is a limitation within a predetermined range. It is precisely this request that the mixing drum of the summer ready-mixed concrete vehicle prevents excessive temperature rise due to solar heat, thereby inducing a proper hydration reaction of the material injected therein to maintain the designed slump value. It is the point of technical thought.

Branched from the lower end side (10) to the upper side (12) of the mixing drum for concrete mixing at predetermined intervals so as not to touch the surface of the rotating drum along its outer circumferential surface and disposed at a predetermined interval. In the middle of at least a part of the length from the lower side 10 to the upper side 12 of the plurality of spraying nozzles or sprinkling holes 14 opening toward the surface of the rotating drum 6 are drilled. Mounting pipe (18) It is configured.
미설명 도면부호 20은 세척용 물탱크(2)로부터 인출된 물을 세척수공급용 파이프(22)로 인출하지 않고 본 고안에 따른 살수용 파이프로(18)로 바이패스 하여 인출하기 위한 개폐조작 레버이다.Reference numeral 20 is an opening / closing control lever for bypassing and drawing the water drawn out from the washing water tank 2 to the watering pipe furnace 18 according to the present invention without drawing the water 22 to the washing water supply pipe 22. to be.
본 고안에 따른 콘크리트 믹싱용 드럼의 과열을 방지하기 위한 살수노즐이 부착된 레미콘 차량은 그 차량의 주행도중 믹싱드럼(6)을 회전시킴으로써 그 내부에 투입된 콘크리트 재료들이 혼합되는 동안 워터펌프(4)에 전원을 온(On)으로 인가하여 워터펌프(4)를 작동하되 세척용 파이프(22)의 유로(流路)를 단속하는 조작레버(미도시) 폐쇄함과 아울러 전술한 살수용 파이프(6)의 유로를 개폐하는 조작레버(20)를 열어 드럼의 외주면 종방향 길이의 적어도 일부에 걸쳐 형성된 살수용 파이프(6)의 살수노즐 또는 살수 구멍(14)을 통해 물을 드럼 외주면에 살포함으로써 태양 직사광선에 의해 과열된 드럼의 온도를 낮출 수 있게 된다.The ready-mixed concrete vehicle equipped with a spray nozzle to prevent overheating of the drum for mixing concrete according to the present invention is rotated by the mixing drum 6 while the vehicle is running while the water pump 4 is mixed with the concrete materials introduced therein. While operating the water pump 4 by applying power to the (On), while closing the operating lever (not shown) to control the flow path of the washing pipe 22, and the above-mentioned watering pipe (6) Sun by opening the operating lever 20 for opening and closing the flow path of the pipe) and spraying water to the drum outer circumferential surface through the spray nozzle or the sprinkling hole 14 of the sprinkling pipe 6 formed over at least a portion of the drum's outer peripheral surface longitudinal length. It is possible to lower the temperature of the drum overheated by direct sunlight.
본 고안에 있어서 드럼 냉각용 살수 파이프(18)는 그 상하단이 소정위치에 고정된 상태에서 물을 분사하지만 드럼이 회전하기 때문에 드럼 외주면 전체에 물이 고르게 뿌려지게 되어 드럼에 대한 냉각효과는 신속하고 확실하게 이루어짐으로써 드럼 내부에서 혼합되는 콘크리트 재료의 물성변화, 특히 과도한 수화반응의 촉진에 따른 슬럼프 값이 설계값보다 떨어지는 현상을 효과적으로 방지할 수 있다.In the present invention, the drum cooling sprinkling pipe 18 sprays water while its upper and lower ends are fixed at a predetermined position, but since the drum rotates, water is evenly sprayed on the entire outer circumferential surface of the drum, so that the cooling effect on the drum is quick. It is possible to effectively prevent the change of the physical properties of the concrete material mixed inside the drum, in particular, the slump value due to the promotion of excessive hydration reaction falls below the design value.
본 고안에 따른 콘크리트 믹싱용 드럼의 과열을 방지하기 위한 살수장치가 부착된 레미콘 차량은 기존의 레미콘 차량의 구성을 그대로 이용하면서 이에 극히 간단한 구성의 살수용 파이프를 워터펌프로부터 인출되는 파이프(8)로부터 분지하여 연결하는 구성에 의해 특히 혹서기(酷暑期)에 레미콘 믹싱드럼이 과열됨으로 인하여 드럼 내부의 콘크리트에 바람직하지 않은 물성변화, 예컨대 슬럼프 값이 줄어드는 것을 방지할 수 있는 효과를 갖는다.The ready-mixed concrete vehicle equipped with a watering device for preventing overheating of the drum for mixing concrete according to the present invention uses the existing ready-mixed concrete vehicle as it is, and the pipe for drawing the watering pipe having an extremely simple configuration from the water pump (8) In particular, due to the configuration of branching from the connection of the ready-mixed concrete mixing drum overheating in the extreme heat (를) has an effect that can prevent undesirable changes in physical properties, such as a slump value to the concrete inside the drum.
