본 발명은 공동구 시공 및 유지관리가 용이한 조립식 난간에 관한 것으로, 더욱 상세하게는 공동구의 출입구를 개폐하는 덮개에 난간을 구성하여 별도로 안전 펜스를 휴대하지 않아도 공동구의 작업 현장에서 난간을 설치할 수 있으며, 덮개의 개폐 동작을 통해 난간이 자연적으로 형성되도록 한 공동구 시공 및 유지관리가 용이한 조립식 난간에 관한 것이다.
The present invention relates to a prefabricated handrail for easy construction and maintenance of the joint ball, and more particularly, by constructing a railing on the cover for opening and closing the entrance and exit of the joint ball, the railing can be installed at the work site of the joint ball without carrying a safety fence separately. The construction is easy and easy to install the handrails and the maintenance of the prefabricated railings to form the railings naturally.

공동구는 노면 굴착을 수반하는 지하 매설물(전기·가스·수도의 공급시설 및 전신선로·하수도시설 등)을 공동수용함으로써 도시의 미관, 도로구조의 보존과 원활한 교통의 유통을 도모하는 지하 시설물을 말한다. 전주와 체신주를 비롯하여 전기 전화선 등 지상 가공선의 설치없이 다양한 설비시설이 공동구내에 집약된다. 따라서 공동구는 한 장소에서 동시에 여러 종류의 설비를 유지 보수할 수 있고 쾌적한 지상공간을 연출할 수 있기 때문에, 새로이 건설되는 신도시, 상업지역, 아파트 단지 등에 적용되고 있다.
The common ward is an underground facility that promotes the preservation of the aesthetics of the city, the road structure and the smooth traffic distribution by jointly accepting underground burials (electricity, gas, water supply facilities, telegraph lines, sewerage facilities, etc.) that accompany road excavation. . Various facilities are concentrated in the premises without the installation of ground overhead lines such as electric poles and telephone poles. Therefore, the common area can be applied to a newly constructed new town, commercial area, apartment complex, etc., since it can maintain various kinds of facilities at the same time and produce a comfortable ground space.

일반적으로 공동구는 도로나 아파트 단지를 건설할 때 공동구의 설치를 위한 공간만큼 땅을 파고 바닥슬래브와 양측벽 및 천장슬래브를 현장 콘크리트 타설에 의해 시공함으로써 형성된다. 건물과 공동구는 건물의 지하 외벽체의 중간부 또는 지하층 바닥에서 연결되며, 전기·가스·수도의 공급시설 및 전신선로·하수도시설 등은 연결부를 지나 건물 내부로 유입되게 된다.In general, the common area is formed by digging the ground as much as the space for installing the common area when constructing a road or an apartment complex, and constructing floor slabs, side walls, and ceiling slabs by in-situ concrete casting. The building and the common premises are connected at the middle or basement floor of the basement outer wall of the building, and the electricity, gas and water supply facilities, the telegraph lines and the sewerage facilities are introduced into the building through the connection.

이와 같은 공동구에는 공동구의 시공 및 유지보수를 위하여 사람이 출입할 수 있는 출입구가 마련된다. 상기 출입구는 지중의 공동구와 지상을 연결하는 통로로서 공동구를 따라 일정 간격을 두고 형성되며 덮개를 통해 개폐된다.Such a common ward is provided with a doorway for a person to enter and exit for construction and maintenance of the common ward. The doorway is a passage connecting the underground cavity and the ground, and is formed at regular intervals along the cavity and is opened and closed through a cover.

종래 공동구의 시공 및 유지보수를 위하여 출입구의 덮개를 열어 공동구를 개방한 후 작업자가 출입구를 통해 지중의 공동구로 내려가서 공동구를 시공 및 유지보수하게 된다.After opening the cover of the entrance to open the cover of the entrance for the construction and maintenance of the conventional cavity, the worker goes down to the cavity of the underground through the entrance to construct and maintain the cavity.

종래 공동구의 시공 및 유지보수의 과정에서 공동구의 출입구가 지상의 구멍 형태로 형성되어 있기 때문에 작업자와 보행자가 공동구의 출입구를 통해 추락하는 사고가 발생되는 문제점이 있으며, 이를 방지하기 위하여 공동구의 작업(시공, 유지보수)시 공동구의 둘레부에 안전 펜스를 설치하게 된다.

Construction, maintenance) will install a safety fence around the circumference of the cavity.

종래 기술에 따르면, 공동구의 작업시 설치하는 안전 펜스가 공동구에 갖추어지지 않았기 때문에 작업자가 안전펜스를 휴대하여야 하는 불편함이 있고, 아울러, 작업의 시작과 종료 시점에서 안전 펜스를 일일이 설치하고 해체하여야 하는데 그 작업이 매우 번거로우며, 이에 따라 안전 펜스를 형식적으로만 설치하여 작업자와 보행자에 의해 안전 펜스가 밀리게 되어 안전 펜스의 기능을 하지 못하는 문제점도 있다.
According to the prior art, since the safety fence to be installed during the work of the joint ball is not equipped in the joint ball, the worker has to carry the safety fence. In addition, the safety fence must be installed and dismantled at the start and end of the work. The work is very cumbersome, and accordingly there is a problem in that the safety fence is pushed by the worker and the pedestrian only by installing the safety fence formally and thus does not function as a safety fence.
