Description

교각철근설치용 안전대{SAFETY RACK FOR BINDING STEEL REINFORCING FOR PIERS}Safety rod for pier rebar installation {SAFETY RACK FOR BINDING STEEL REINFORCING FOR PIERS}

본 발명은 교량의 교각 설치공사에서 철근 엮음 설치공사를 위하여 사용하는 안전대에 관한 것이다.The present invention relates to a safety belt used for reinforcing bar installation work in bridge piers installation work.

일반적으로 교각 콘크리트 시공용 철근을 엮는 작업을 할때는 지면에 가까운 높이일때는 사람이 지상에 서서 철근을 역어나갈 수 있지만 일정높이 이상 콘크리트 교각(100)이 시공된 상태에서는 거푸집(70)상단의 측면에 브라켓(80)에 의해 지지되는 추락방지용 안전울타리(90)를 설치하고 그 울타리의 바닥에는 미끄러지지 않게 발판(6)을 깔고 그 발판위에서 철근 역음작업을 하다가 작업높이 이상이 되면 안전울타리를 상부로 이동시킬 수가 없기 때문에 엮어진 철근에 로프로 몸을 묶어서 의지한채 철근 엮는 작업을 계속하게되므로 작업이 원활치 못할뿐 아니라 추락사고의 위험성이 많은 불편이 있었다.In general, when weaving reinforcing bars for pier concrete construction, when the height is close to the ground, a person can stand on the ground and retract the rebar, but when the concrete pier (100) is constructed above a certain height, the side of the formwork (70) is on the upper side. Install the fall prevention safety fence (90) supported by the bracket (80) and install the footrest (6) on the bottom of the fence so that it does not slip, and the reinforcing bart work on the footboard, when the working height is higher than the safety fence moves upwards Since it is impossible to make the reinforcing bar relying on the reinforcing steel bars with ropes, the work is not smooth, and there is a lot of inconvenience of falling accidents.

본 발명은 상기한 바와같은 교각 설치시 이용되는 추락방지용 안전울타리의 결점을 해소하기 위하여 상기 거푸집에 연결설치된 추락방지용 기존 안전울타리상에 필요한 높이의 안전대를 다단으로 포갠다음 그 최상단의 작업용 안전대에서 안전한 상태로 올라서서 철근 엮음 작업을 할 수 있게한 교각 콘크리트 시공용 철근 설치용 안전대에 관한 것으로서 이를 첨부된 도면을 참조하면서 상세히 설명하면 다음과 같다.The present invention, in order to eliminate the drawback of the fall prevention safety fence used in the installation of the pier as described above, the safety harness of the height required on the fall prevention existing safety fence connected to the formwork is stacked in multiple stages and the safety work safety at the top Regarding the safety belt for the reinforcing rod construction for the pier concrete construction that can be raised to work in the state of reinforcement, it will be described in detail with reference to the accompanying drawings.

일정간격으로 가로 세로 ＋자형으로 교차되게 다수개의 가로봉(2)과 세로봉(1)을 용접하여서된 반원통형이나 ㄷ자형 단위체(13)나 창살문형단위체(13')를 사람의 통행이 가능한 폭만큼의 직경이나 폭이 다른 두개의 내외통(7)(8)으로 구성하여 상기 단위체가 서로 인접하는 측면부위를 볼트 너트(5)로 교정하여 거푸집 넓이보다 약간 큰 원형이나 타원형 또는 각형 모양의 통형태중에서 선택된 어느 한가지 통형태로 안전대본체(6)를 형성하되, 상기 안전대본체(6)의 내외통(7)(8)을 이루는 상기 반원통형 단위체(13)나 창살문형 단위체(13')의 상하단 사이에는 일정간격으로 연결봉(9)으로 연결하여 상기 연결봉(9)으로 연결된 내외통(7)(8)사이에 망상의 안전발판(10)을 고정설치하고 상단의 외측면에는 일정간격마다 다수개의 수직 지지봉(3)을 고정설치하여 다른 안전대의 단위체를 그 위에 중첩시에 그 지지봉(3)내에 지지되면서 중첩설치될 수 있게하고, 최상단의 작업용안전대(14)는 상기 반원통형 단위체와 창살문형단위체(13')로된 외통(8)만으로 구성하며 상기 안전대(6)의 상단이나 하단의 가로봉(2)에는 다른 또 하나의 안전대본체(6)의 가로봉(2)을 잡아 고정할 다수개의 ㄷ자형 크램프(4)를 하향되게 비치하고 상기 내외통(7)(8)사이의 일정위치에는 상하로 사람이 오르내릴 수 있는 사다리계단(11)과 상하 출입구(12)을 설치한 것으로 구성된다.The width that allows people to pass through a semi-cylindrical, t-shaped unit (13), or grate-shaped unit (13 ') by welding a plurality of horizontal bars (2) and vertical bars (1) so as to intersect horizontally and vertically at regular intervals. Consists of two inner and outer cylinders 7 and 8 with different diameters or widths, and corrects the side portions of the unit adjacent to each other with bolt nuts 5 so as to have a circular, elliptical or angular tube slightly larger than the mold width. The semi-cylindrical unit 13 or the grate door unit 13 'which forms the safety main body 6 in any one cylindrical shape selected from the above forms and forms the inner and outer cylinders 7 and 8 of the safety main body 6. Between the upper and lower ends connected to the connecting rod (9) at regular intervals between the inner and outer cylinders (7) (8) connected by the connecting rod (9) fixed to install the safety footrest (10) of the mesh and a plurality of at regular intervals on the outer surface of the top Two vertical support rods (3) The unit of the squadron can be superimposed and supported in the supporting rod 3 when it is superimposed thereon, and the uppermost work safety stand 14 has an outer cylinder 8 composed of the semi-cylindrical unit and the grate door unit 13 '. It consists of a bay and the horizontal bar (2) at the top or bottom of the safety belt (6) is provided with a plurality of c-shaped clamps (4) to hold and secure the horizontal bar (2) of another safety guard main body 6 and downward At a predetermined position between the inner and outer cylinders 7 and 8, a ladder stair 11 and a vertical entrance / exit 12 are provided for allowing a person to move up and down.

상기에서 안전대(6)의 형태를 원통형으로 하고져 할때는 중간의 창살문형 단위체(13')는 제거한채 반원통형 단위체(13)두개를 맞붙여 결합하면 되고 정.직사각형의 형태로 하고져 할때는 반원통형 단위체대신 ㄷ자형단위체들만 결합하거나 ㄷ자형 단위체와 창살문형단위체를 결합하면 된다.In the above, when the shape of the safety belt 6 is to be cylindrical, the middle grate door unit 13 'is removed, and the two semi-cylindrical units 13 are joined together to be bonded together. You can combine only the U-shaped units or the U-shaped unit and the grate unit.

이상과 같이 구성되는 본 발명 교각철근설치용 안전대는 기존의 교각 설치용 거푸집의 상단에 설치되는 추락방지용 안전대(울다리)내에 일단 본 발명의 단위체(13)(13')들에 의해 조립된 한 세트의 안전대(6)만을 크레인으로 들어서 장착하고 그위에 또한 세트의 낮은 안전대(6)를 중첩 설치하거나 바로 그위에 내통(7)이 없는 외통(8)만으로된 작업용 안전대(14)를 설치하게 되면 안전대 본체(6)상단과 작업용안전대(14) 외측면에 상향고정된 다수개의 수직 지지봉(3)내로 새로중첩 설치되는 상부 안전대 본체(6)나 작업용 안전대(14)의 하단부가 차례로 걸려 지지되게 되어 안착되므로 사람이 망상의 안전발판(10)위에서 안전한 상태로 서서 철근 엮음작업을 할 수 있고 이와같이 작업을 계속하는동안 철근 높이가 높아지고 교각콘크리트타설공사를 계속하여 상향으로 하게될때는 안전대(6)와 작업용안전대(14)를 모두 크레인으로 들어서 상부로 차례로 이동시킨 후 콘크리트타설을 하면되고 다시 다른지역에서 철근 엮음작업을 계속하려면 다시 기존의 거푸집상의 안전울타리에 본 발명 안전대본체(6)와 작업용 안전대(14)를 크레인으로 옮겨 상기한 바와같이 장착한 후 작업을 반복하게 되면 종래와 같은 비계(발판)설치를 위해 며칠에 걸쳐 작업할 필요없이 쉽게 크레인으로 안전대본체(6)와 작업용안전대(14)를 이동설치할 수가 있으므로 철근 엮음작업에 따른 인적, 물적, 시간적 손실이 적고 작업원가가 절감되게 되며, 또한 본 발명 안전대본체(6) 및 작업안전대(14)는 안전대상의 망상의 안전발판(10)에서 작업을 하면서 내외통(7)(8)으로 보호되므로 작업중 추락등 안전사고의 위험성이 전혀 없게된다.The pier reinforcing rod safety bar of the present invention constituted as described above is a set of once assembled by the unit (13, 13 ') of the present invention in the fall prevention harness (leg) installed on the top of the existing pier installation formwork. If only the safety harness 6 is mounted by a crane and the lower safety harness 6 of the set is superimposed thereon or the work safety harness 14 which is composed of only the outer cylinder 8 without the inner casing 7 directly thereon, (6) Since the upper and the safety belt body (6) newly installed in the plurality of vertical support rods (3) fixed upward on the outer surface of the work safety belt (14) or the lower end of the work safety belt (14) is hung and supported in turn. A person can stand in a safe state on the deportable scaffold (10) and we can perform reinforcing bars. In this way, the height of the reinforcing bar is increased and the pier concrete laying work is continued. When the safety belt (6) and the work safety belt (14) to lift the crane in order to move up to the top and then put the concrete in order to continue the reinforcing the steel bar in another area again in the existing formwork safety fence When the safety main body 6 and the work safety belt 14 are moved to the crane and mounted as described above, and the work is repeated, the safety main body (e.g., the scaffolding) can be easily installed without the need for working for several days to install the scaffolding (stool). 6) and the work safety belt 14 can be moved and installed, so the human, material, and time loss due to reinforcing the steel bar work is reduced and the working cost is reduced, and also the safety main body 6 and the work safety belt 14 of the present invention are safety targets. While working on the reticular safety scaffold 10 of the inner and outer cylinder (7) (8) is protected so there is no risk of safety accidents such as falls during work.

본 발명 교각 철근 설치용 안전대는 기존의 교각 콘크리트 타설용 거푸집 상단에 형성된 안전대상에 중첩 설치하면서 철근엮음 작업을 할 수 있으므로 추락방지등 안전사고의 예방효과는 물론 이동설치가 간편하여 작업능률을 향상시키고 인건비를 절약하여 전체공사비용을 절감할 수 있는 효과가 있다.In the present invention, the pier reinforcing rod safety bar can be installed while overlapping the safety target formed on the top of the existing formwork for pier concrete placing, so as to prevent the fall of safety accidents, such as fall prevention, as well as easy to install and improve the work efficiency The labor cost can be reduced and the overall construction cost can be reduced.
