Abstract

지하연속벽에 의한 토목공사에 있어서 양생된 연속벽이 불균일하게 오버블로우현상이 있는 바 이같은 오버블로우 부분을 본 고안자가 제공한 회전식 콘크리트면삭기 및 그에 사용되는 초경팁등의 장치를 이용하여 다듬어주고 있으나 면절삭과 다듬기 작업이 별도로 진행되어 작업효율성이 낮고 다듬어진 표면의 균일성이 확보되지 못한다는 문제가 있었다.In the civil engineering work by underground continuous wall, the cured continuous wall is unevenly overblown, and the overblowing part is trimmed by using the rotary concrete face grinder provided by the inventor and the cemented carbide tip. However, there was a problem that the surface cutting and smoothing work were performed separately, so that the work efficiency was low and the uniformity of the polished surface could not be secured.

본 고안은 전열에 절삭용 콘크리트면삭기를 설치하고 그 후열에 면다듬기용 콘크리트면삭기를 설치한 이중구조의 콘크리트면삭기를 제공하므로서 오버블로우의 절삭과 동시에 면다듬기가 가능토록 하므로서 상기한 문제점들을 해소한 것이다.The present invention solves the above problems by providing a double-sided concrete face cutter equipped with a concrete face cutter for heat transfer and a face machine for face trimming in the heat transfer. .

본 고안은 콘크리트 표면의 절삭과 동시에 면다듬기 기능을 겸비한 콘크리트면삭기에 관한 것이다.The present invention relates to a concrete face grinder having a function of smoothing a surface while simultaneously cutting the concrete surface.

대형빌딩 또는 수로공사등과 같은 토목 기초공사에 있어서 토류벽등을 시공할 경우 공사의 신속성과 작업공간 확보를 위하여 거푸집을 사용하지 않고 지하연속벽시공법을 채택하고 있다. 지하연속벽시공법은 버킷을 이용하여 도랑을 굴삭한 다음 직접 콘크리트를 타설하여 양생하기 때문에 시공도에 구애받지 아니한다는 특징이 있다. 그러나 양생된 지하연속벽의 측면이 토양의 강도가 불균일하므로 토성이 약한 부분에 있는 콘크리트가 튀어나오는 현상(오버블로우)이 종종 발생하므로 이 부위를 소정의 설계기준에 맞도록 절개하고 있다. 이 절개작업에 이용되는 장치가 소위 브래커라는 장비로서 치젤을 탄발력 있게 오버블로우 부위에 타격케 하면 충격에 의하여 파괴절삭되는 것이다. 이같은 다순 파괴절삭은 오버블로우 부위외에 기타 근접부위까지 함께 절개되어져 원하는 설계기준에 맞출 수 없게 하였다.In case of constructing earth wall in civil engineering works such as large building or waterway construction, underground continuous wall construction method is adopted without using formwork for speedy construction and securing working space. The underground continuous wall construction method is not limited to the construction drawing because it excises the trench using a bucket and then cures by pouring concrete directly. However, the side of the cured underground continuous wall is uneven in strength of the soil, so the concrete in the weak Saturn popping out (overblowing) often occurs, so this part is cut to meet the predetermined design criteria. The device used for this cutting operation is a so-called breaker, and if the chisel hits the overblowing area elastically, it is destroyed by impact. Such multi-stage fracture cutting was cut together with the overblow and other adjacent parts, so that they could not meet the desired design criteria.

이같은 단점을 개선하고자 본 고안자는 특허출원 제92-1294호 회전식 콘크리트면삭기 및 그에 사용되는 초경팁을 개발하여 굴삭기의 둠에 부착하여 지하연속벽의 내측에 형성된 오버블로우 부위를 깍아낼 수 있게 하였다. 이 경우에도 공사현장의 특성상 4귀나 바닥등에는 대형 굴삭기가 근접할 수 없어 이들 부위를 절삭하는 장치로서 실용신안 제94-27996호 휴대용 회전식 콘크리트면삭기를 개발하여 귀퉁이 바닥 부근등을 직접 수동으로 깍아낼 수 있게 하였다.In order to improve this disadvantage, the present inventors developed Patent Application No. 92-1294 rotary concrete excavators and carbide tips used therein to attach them to the excavator's dum so that the overblowing areas formed on the inner side of the underground continuous wall could be cut out. . Even in this case, due to the nature of the construction site, large excavators cannot approach close to the four ears or the floor, and as a device for cutting these areas, the utility model 94-27996 developed a portable rotary concrete face excavator to manually cut off corners and corners. Made it possible.

이상의 회전식 콘크리트면삭기는 나름대로 표면정리에 큰 도움을 주고는 있으나 절삭작업이 상·하로 진행되므로 진행방향에서 벗어난 경우, 즉 굴삭기의 압박강도와 회전속도등에 따라서 절삭 깊이가 불균일하여 상·하로 길게 흠이 파이는 형태를 보이고 있다. 이같은 단점을 개선코자 회전판식 콘크리트면삭기를 별도로 고안하여 제공하였으나 면다듬기 기능외에는 필요한 정도의 절삭속도가 보장되지 못하여 공사 진행속도에 지장이 있었다.The above-mentioned rotary concrete facer is very helpful for surface cleaning in its own way, but the cutting work proceeds up and down, so if it is out of the direction of progress, that is, the cutting depth is uneven depending on the pressure and rotation speed of the excavator, so that the flaw is long and long. Pie is showing shape. In order to improve such disadvantages, the rotary plate concrete face grinder was devised and provided separately, but the cutting speed was not guaranteed as well as the surface smoothing function.

본 고안은 이같은 단점을 개선코자 안출한 것으로서 전열에 절삭용 콘크리트면삭기를 설치하고 그 후열에 면다듬기용 콘크리트면삭기를 설치한 이중구조의 콘크리트면삭기를 제공하므로서 오버블로우의 절삭과 동시에 면다듬기가 가능토록 하였다.The present invention has been devised to improve such disadvantages, and provides a double-sided concrete face cutter with a concrete face cutter installed in the front row and a face cutter in the rear row, so that the face can be trimmed at the same time as the overblowing. It was.

이하 본 고안의 구체적인 예를 도면에 의하여 설명한다.Hereinafter, specific examples of the present invention will be described with reference to the drawings.

제1도는 본 고안의 콘크리트면삭기의 평면도로서 구동모터(1)가 하우징(2)의 일측에 돌출되게 또는 내장되도록 설치되어지며 하우징의 하단은 전동기어부(3)를 감싼 기어지지부와 연결되어 양측에 한쌍씩의 면삭기드럼이 설치되어 있다.1 is a plan view of a concrete face grinder according to the present invention, and the driving motor 1 is installed to protrude or be embedded in one side of the housing 2, and the lower end of the housing is connected to a gear support part surrounding the electric gear part 3, and is connected to both sides. There is a pair of plane drums in the

제2도에서는 본 고안의 측면구조도로서 구동모터를 내장하는 하우징(2)이 하부쪽으로 기어전동부(3)를 함께 내장토록하여 각각의 기어전동부(3)에는 상·하·좌·우의 방향으로 4개의 구동축(5-1)(5-2)(5-3)(5-4)을 뽑아내어 회전드럼의 중앙과 일체화 하였고, 하우징(2)의 상면 일측에는 고정브라켓트(2a)를 연결폴(2b)에 의하여 둠과 핀 또는 볼트등의 고정구(7)로 직결하며 타측에는 스프링 리테이너부(8)를 두어 탄발력 있는 스프링(9)이 둠과의 사이에 지지되어 지도록 하였다.In FIG. 2, as a side structural diagram of the present invention, the housing 2 incorporating the drive motor has the gear transmission 3 embedded therein so that the gear transmission 3 has the directions of up, down, left, and right directions. 4 drive shafts (5-1), (5-2), (5-3) and (5-4) were extracted and integrated with the center of the rotating drum, and the fixing bracket (2a) was connected to one side of the upper surface of the housing (2). The pawl 2b is directly connected to the dome and the fixture 7 such as a pin or bolt, and the spring retainer 8 is placed on the other side so that the elastic spring 9 is supported between the doom.

회전드럼은 본 고안의 경우 4개를 제시하고 있으나, 필요에 따라서 3쌍이상 연속결합시켜주어 작업 효율성을 높일 수 있으며 이 경우에 구동모터의 구동력만 증강시켜 주면 동작에는 무리가 없는 것이다.In the present invention, four rotary drums are proposed, but if necessary, three or more pairs can be combined continuously to increase work efficiency. In this case, if the driving force of the driving motor is enhanced, there is no problem in operation.

본 고안에서 회전드럼은 전열에 2개의 절삭용 회전드럼(10)(11)을 설치하여 그 후열에 역시 2개의 면다듬기용 회전드럼(12)(13)을 설치하여 준 것을 예시하는 바, 전열의 회전드럼(10)(11)에는 절삭용 초경팁(14)이 다수개 생크에 부착 고정된 커팅날을 사용하였으며, 후열의 회전드럼(12)(13)에는 면다듬기용 초경팁(15)을 다수개 생크에 부착한 커팅날을 사용하였다.In the present invention, the rotating drum is provided with two cutting drums 10 and 11 for cutting in the heat transfer, and two rotary drums 12 and 13 for smoothing in the rear row are illustrated. In the rotating drum (10) (11) of the cutting carbide tip 14 was used a fixed cutting blade attached to a plurality of shanks, the rear end of the rotating drum (12) (13) for carbide trimming tips (15) A cutting blade attached to a plurality of shanks was used.

커팅날에 부착되는 초경팁의 숫자는 필요에 따라서 2이상 부착할 수 있으며 배열위치도 동일원주상에 교호 또는 방사상으로 엇갈리게 배치하여 절삭과 다듬기의 효율을 최적화 할 수 있다.The number of cemented carbide tips attached to the cutting edge can be attached to two or more if necessary, and the arrangement positions can be alternately or radially staggered on the same circumference to optimize the efficiency of cutting and trimming.

본 고안의 면삭기는 면삭처리가 필요한 부위에 본 고안의 전열에 있는 회전드럼(10)(11)을 서서히 갖다대면 절삭용 초경팁(14)이 회전력에 의하여 콘크리트표면에 파고들어 깍아주게 되며 이어서 동일평면에 배치되어 있는 회전드럼(12)(13)이 연이어 절삭면을 추적하게 되므로 절삭된 면의 다듬기 작업이 진행되는 것이다.When the face grinder of the present invention is slowly brought to the rotary drum (10) (11) in the heat transfer of the present invention in the area where the surface treatment is required, the cutting carbide tip (14) is cut into the concrete surface by the rotational force and then shaved. Since the rotating drums 12 and 13 arranged in the plane track the cutting surface successively, the cutting operation of the cut surface is performed.

따라서 오버블로우 부위를 절개하는 동시에 평평하게 면다듬기를 동시에 처리할 수 있어 작업의 신속성은 물론 절개표면에 대한 고정밀한 표면처리가 가능하여 공사후에 다른 후처리가 일체 필요없게 된다는 특징이 있는 것이다.Therefore, it is possible to simultaneously process the surface smoothing while cutting the overblowing part, so that the work can be done quickly and the surface can be precisely processed on the incision surface, so that no other post-treatment is required after construction.
