본 발명은 콘크리트 펌프카의 콘크리트이송관 말단용 개폐장치에 관한 것으로, 더욱 구체적으로 설명하면, 건물, 교각 또는 도로 등의 건설시에 필요한 콘크리트를 타설하기 위한 콘크리트 펌프카의 콘크리트이송관의 말단에 설치되어 일단 콘크리트타설작업이 종료되면 말단을 폐쇄시키고 콘크리트이송관을 다른 타설장소로 이송시킨 다음에 다시 개방시켜 콘크리트의 타설이 가능하게 되어 콘크리트이송관내에 잔존하는 콘크리트의 사용을 효과적으로 사용하는 것이 가능하게 되어 콘크리트의 효율적인 사용이 가능하게 됨은 물론이고 콘크리트의 타설에 걸리는 시간도 단축되어 효과적인 콘크리트의 타설이 가능한 콘크리트 펌프카의 콘크리트이송관 말단용 개폐장치에 관한 것이다.
The present invention relates to a concrete pump car opening / closing apparatus for a concrete conveyance pipe end. More specifically, the present invention relates to a concrete pump car for installing a concrete, a concrete pillar, When the pouring work is finished, the end is closed and the concrete pipe is transported to another pouring place, and then the pouring pipe can be opened again to enable the pouring of the concrete. Thus, the use of the concrete remaining in the concrete conveying pipe can be effectively used, The present invention relates to a concrete pumping car concrete pail car which can reduce the time required for pouring concrete into the concrete pail.

현재 건설현장에서 널리 사용되고 있는 콘크리트 펌프카는 그 효율적인 장비의 개발로 인하여 수평도달거리와 수직도달거리가 점점 확대되는 추세에 있으며, 콘크리트 펌프카는 기계적인 효율이 대단히 높게 되어 건설현장에서 많은 건설인력들을 대체하는 장비로 각광을 받고 있으며 점점 대형화되어 가는 추세에 있다.Concrete pump cars, widely used in construction sites, are increasing in horizontal reach and vertical reach due to the development of efficient equipments. Concrete pump cars have very high mechanical efficiency, And it is getting larger and larger.

따라서, 콘크리트 펌프카의 수평도달거리와 수직도달거리가 점점 확대되는 과정에서 콘크리트이송관도 점점 길어지고 있으며, 현재까지 있는 콘크리트 펌프카의 수평도달거리, 즉, 콘크리트이송관의 최대길이는 50m 이상의 콘크리트이송관도 사용되고 있다.Therefore, the concrete conveying pipe is gradually getting longer in the course of the horizontal reaching distance and the vertical reaching distance of the concrete pump car increasing gradually, and the horizontal reaching distance of the concrete pump car to the present, that is, the maximum length of the concrete conveying pipe, have.

그러나, 이와 같이 콘크리트이송관의 길이가 길어질수록 콘크리트 타설현장에서는 콘크리트 타설작업이 대단히 간편하게 수행되며 인력이 절감되는 장점은 있으나, 도 1에 도시된 바와 같이, 콘크리트이송관이 포물선형태를 갖게 최대로 전개된 상태에서 콘크리트의 타설작업이 종료될 경우에는, 콘크리트이송관(C)의 하방으로 배치된 콘크리트이송관(C1)내에 충진된 콘크리트는 당연히 배출되어야 하므로 이러한 콘크리트의 배출은 필요에 의한 배출이 아니므로 콘크리트의 낭비가 이루어진다고 할 수가 있는 것이며 이와 같이 낭비되는 콘크리트의 양은 도달거리가 길어질수록 커지게 되어 평균적으로 1회당 콘크리트이송용 리어카의 2 내지 4대 분량에 해당되는 콘크리트양이 낭비되게 되며, 또한 하방으로 배치된 콘크리트이송관(C1)내에 충진된 콘크리트의 배출에 소요되는 시간이 약 2분에서 5분 정도가 소요되므로 콘크리트 타설작업이 지연되는 것은 물론이고 콘크리트의 타설작업에 동원되는 다른 작업인부들이 그 시간 동안에는 놀게 되므로 노동생산성이 저하되게 되는 문제점이 있었다.
However, as the length of the concrete conveyance pipe becomes longer as described above, there is an advantage that the concrete pouring work is very easily performed and the workforce is reduced at the concrete pouring site. However, as shown in FIG. 1, the concrete conveyance pipe is maximally deployed The concrete filled in the concrete conveyance pipe C1 disposed under the concrete conveyance pipe C is naturally discharged, so that the discharge of the concrete is not necessary discharge, and therefore, the concrete The amount of waste concrete wasted becomes larger as the reaching distance becomes longer. As a result, the amount of concrete corresponding to 2 to 4 times the amount of concrete for each conveyance is wasted on an average, and the amount of concrete (C1) filled in the concrete conveyance pipe It takes about 2 to 5 minutes to drain the litter, so that not only the concrete pouring work is delayed but also the labor productivity is lowered because other workers who are involved in pouring concrete play during that time .

본 발명의 목적은, 이러한 문제점을 해결하기 위한 것으로, 콘크리트 펌프카용 콘크리트이송관의 말단에 콘크리트이송관을 개폐시키는 개폐장치를 부착하여 콘크리트의 타설작업이 종료되면 콘크리트이송관을 폐쇄시키는 동시에 다른 장소로 콘크리트이송관을 이동시키고 폐쇄된 콘크리트이송관을 개방시켜 콘크리트의 타설작업이 연속적으로 진행시킬 수가 있게 되므로 필요한 양만큼의 콘크리트의 타설이 이루어지게 되므로 콘크리트의 효율적인 사용이 이루어지게 되는 것은 물론이고 다른 장소에서 즉시에 콘크리트의 타설이 이루어지게 되므로서 콘크리트의 타설시간이 단축되어 공기가 단축되고, 콘크리트의 타설작업에 동원된 인부들도 즉시 콘크리트의 타설작업에 동원되는 것이 가능하게 되어 노동생산성이 향상되는 것이 가능한 콘크리트 펌프카의 콘크리트이송관 말단용 개폐장치를 제공하는 것이다.
