Description

Buried cable piping box plug {Buried cable piping box plug}

The present invention relates to a plug of a buried cable piping box, and more specifically, in the laying work of cable piping for wiring electrical/communication cables in building construction, etc. It relates to a plug for a buried type cable pipe box that improves work stability of the cable pipe by preventing it from flowing in and improves work efficiency by simply separating and combining the cap.

In general, when building a building, cable pipes are laid to wire electric/communication cables, etc. These cable pipes are built into the future pipe in the building and buried with concrete mortar.

Therefore, there is a high possibility that various foreign substances such as cement and sand, in addition to concrete mortar, may enter the cable piping in which the cables such as electricity and communication are routed in the open direction. It causes a lot of problems, such as blocking or damaging the cable during the cable lead-in operation.

Hereinafter, this will be described in more detail.

When constructing a building, cable piping is pre-arranged inside the form for wiring electrical and communication cables, and wiring boxes for wiring outlets and switches are installed inside the form, and then concrete mortar is poured and cured to complete it.

However, in the process of laying the cable pipe, since the cable pipe through which the electric/communication cable enters is open, there is a high risk of foreign substances such as cement and sand as well as concrete mortar easily entering the inside. causes

In order to solve this problem, conventionally, the efficiency of cable piping work is reduced by covering the open part of the cable piping with plastic, paper, etc., and after the concrete mortar is buried, the cover is removed for cable entry. As a result, the burial and wiring of the cable pipe was very inefficient.

Hereinafter, we will look at the prior art related to cable piping.

Reference 1 discloses a connector for preventing foreign substances from penetrating in a wiring pipe by forming a plug for preventing foreign substances from entering the upper part of the contactor of the electrical distribution case to prevent foreign substances from penetrating during construction and allowing the plug to be easily removed during electrical wiring. has been

In Reference 2, it is composed of a body and a position indicator for preventing the inflow of concrete mortar to prevent concrete mortar from flowing into the electric piping box and a temporary stopper for an electrical piping box in which a position indicator is formed so that the buried position can be identified. .

In addition, Reference 3 describes the attachment of a stopper to the fixing screw insertion hole of an embedded junction box so that concrete mortar does not flow in during the installation process of the junction box, and Reference 4 describes the connection formed on both sides of the terminal block case of the communication terminal box. It describes how to prevent foreign substances such as concrete mortar from entering the inside of the case of the terminal box through the socket by attaching the stopper to the guide hole of the socket for use.
