본 고안은 옥내배선공사시의 건물천장에 배선되는 전기선이나 전화선 또는 TV안테나선 등을 분산 및 접속시키기 위한 콘크리트실링박스용 컨넥터에 관한 것으로, 보다 상세하게는 콘크리트실링박스와의 체결작업이 용이하면서도 콘크리트 타설작업시의 접촉파손을 막을 수 있고 아울러 천장바닥과의 사이에 콘크리트가 구조적으로 충분하게 타설분포될 수 있도록 한 콘크리트실링박스용 컨넥터에 관한 것이다.The present invention relates to a connector for a concrete sealing box for distributing and connecting electric wires, telephone lines, or TV antenna wires that are wired to a building ceiling during indoor wiring work, and more specifically, it is easy to fasten with a concrete sealing box. The present invention relates to a connector for a concrete sealing box, which can prevent contact breakage during concrete pouring work and also allow the concrete to be sufficiently structurally distributed between the floor and the ceiling.

일반적으로 아파트나 빌딩과 같은 건축물의 전기선이나 전화선 또는 TV안테나선 등의 배관공사에 사용되는 옥내배관용 콘크리트박스는, 건물공사시의 콘크리트 타설작업에 앞서 건물천장이나 건물내벽의 철근 사이에 취부되어 해당 가요성의 전선관을 접속 및 분산시킬 수 있도록 구성되어 있으며, 이때 이들 옥내배관용 콘크리트박스인 건물천장의 콘크리트실링박스나 건물내벽의 콘크리트월박스를 통해 배관분기되는 전선관은 해당 방향으로의 컨넥터를 통해 상기 콘크리트스위치박스에 연결설치될 수 있었고, 아울러 이들 컨넥터가 체결된 콘크리트박스 및 전선관 위로 콘크리트 타설작업이 이루어졌다.In general, concrete boxes for indoor piping, which are used for plumbing such as electric wires, telephone lines, or TV antennas of buildings such as apartments or buildings, are mounted between the ceiling of the building and the reinforcing walls of the building walls prior to the concrete placement work. It is configured to connect and disperse the flexible conduits. In this case, the conduits branched through the concrete ceiling box of the ceiling of the building, or the concrete wall box of the wall of the building, are connected in the direction. The concrete switch box could be connected and installed, and concrete pouring work was done on the concrete box and conduit to which these connectors were fastened.

한편, 이들 전선관들이 접속 및 분기되는 콘크리트박스는 건물천장 및 건물내벽의 옥내배관용으로 각각 콘크리트실링박스(concrete ceilng box) 및 콘크리트월박스(concrete wall box)로써 그 외부구조 및 설치방법을 달리하여 사용되고 있다.Meanwhile, the concrete boxes to which these conduits are connected and branched are concrete ceilng boxes and concrete wall boxes for indoor piping of building ceilings and interior walls, respectively. It is used.

특히, 건물천장용으로 적용되는 콘크리트실링박스에는 통상 전선관들이 3-4방향으로 연결접속되는 8각형태 및 다중방향으로 연결접속되는 4각형태의 상기 콘크리트실링박스에 컨넥터가 취부고정된다.In particular, the concrete sealing box is applied to the ceiling, the connector is fixed to the concrete sealing box of the octagonal form in which the conduits are connected in 3-4 directions and the octagonal form connected in multiple directions.

이러한, 건물천장용 콘크리트실링박스에 취부적용되는 종래의 컨넥터는, 통상 콘크리트실링박스의 컨넥터결합공에 일자형의 상기 컨넥터가 서로 나사체결되어 천장바닥재 위에 일정간격을 두고 수평으로 위치고정되었다.In the conventional ceiling mounted ceiling sealing box, such connectors are generally horizontally fixed at a predetermined interval on the ceiling floor by screwing the straight connectors into the connector coupling holes of the concrete ceiling box.

따라서, 콘크리트 타설작업시에 이들 전선관이 연결된 콘크리스실링박스의 해당 컨넥터가 작업자의 발에 의해 밟혀질 경우 아래쪽으로 쉽게 눌려지면서 파손될 위험이 많았으며, 특히 천장바닥재와 수평구조인 컨넥터와의 사이가 주변에 비해 상대적으로 좁아 결과적으로 이들 사이의 콘크리트의 타설두께가 얇아짐에 따라 천장바닥의 콘크리트 양생강도가 부분적으로 취약할 수 있다는 문제점이 있었다.Therefore, when concrete connectors are stepped on by the operator's foot when the corresponding connector of the concrete sealing box to which these conduits are connected is easily pressed downward, there is a high risk of breakage. In particular, the space between the ceiling floor and the horizontal connector As it is relatively narrow compared to the surroundings, as a result, the thickness of the concrete between them becomes thin, there is a problem that the concrete curing strength of the ceiling floor may be partially weak.

이에 본 고안은 상기와 같은 상황을 감안하여 안출한 것으로, 콘크리트실링박스와의 체결작업이 원터치로 간단하면서도 확실하게 위치고정이 이루어질 수 있고, 아울러 콘크리트 타설작업시의 작업자의 접촉가압에 의한 이탈파손을 막을 수 있으면서 콘크리트가 구조적으로 충분하게 타설분포될 수 있도록 하는 콘크리트실링박스용 컨넥터를 제공함에 그 목적이 있다.The present invention has been devised in view of the above situation, and the fastening work with the concrete sealing box can be easily and securely fixed in one touch, and the breakage damage caused by the contact pressure of the worker during the concrete placing work can be achieved. The purpose of the present invention is to provide a connector for a concrete sealing box that can prevent the concrete to be sufficiently poured in the structural distribution.
