Description

Foundation Box {FOUNDATION BOX}

BACKGROUND OF THE INVENTION In the foundation of electric poles (hereinafter, mainly referred to as street lamps) such as street lamps, traffic lights, and self-supporting distribution boxes for street lamps, the present invention relates to a basic box for facilitating the fabrication of electric wires including conduits and street lamps.

The foundation for installing the street lamp is provided with a foundation bolt or nut to secure the pipe and the street line and the pipe formed so that the external wire can be inserted into the street lamp.
In general, the base fabrication of streetlights
Foundation bolts or nuts which are formed so as to correspond to the upper and side surfaces of the foundation upside down, that is, the upper formwork is located on the bottom surface, and the foundation bolts or nuts for fixing the conduit and the street lamps to form a conduit or a conduit therein It is prepared to maintain a constant height and spacing, and then cast concrete and remove the formwork when the concrete is cured.
The conventional street lamp main pipe line is not exposed from the outside to prevent the entry of foreign matter into the pipe line after the manufacturing process or production.
And the bolt reinforcing bar 32 to prevent the foundation bolts shown in the city and paragraph number 71 of Fig. 3 is not distracted or fell due to the concrete placing, the Patent Publication No. 10-0853099 (2008.08.19)
It takes a lot of time and effort to connect each other with a foundation bolt, screwing, welding, wire, etc., and generally use the " ㅁ " bolt reinforcing rod as shown in FIG. It is preferable to provide two or more places.
The bolt fixing part formed to be able to insert the foundation bolt of the Utility Model Registration No. 20-0216697 (2001.03.15),
In order to maintain a constant gap and height of the nut 320 shown in Figures 2 and 3 due to concrete pouring without disturbing, it is necessary to be firmly coupled to the outer girdle and also to prevent foreign substances from entering the nut. It is necessary to supplement the nut connecting the lamp post with the street lamp to prevent it from coming off the foundation.
In addition, the L-shaped fixing groove 260 shown in FIGS. 4 and 5 requires considerable time and effort to form, install, and remove the formwork corresponding to the EL-type fixing groove in order to form the EL fixing groove. .

The manhole presented in Registration Utility Model Publication No. 20-0196174 (September 15, 2000),
A streetlight foundation and manhole was proposed to further install a drainage pipe for discharging water flowing into the manhole, as well as a first pipe connecting the manhole to the outside and a second pipe connecting the manhole to the interior of the street lamp.

However, in order to manufacture the manhole, the manhole formwork must be removed after fabrication, installation, and curing of the concrete so that it cannot be transformed into concrete casting, and it takes considerable effort and time to fix and install the manhole formwork and the first and second pipelines connecting to the outside. .

Therefore, it may be considered to improve the structural part of the street lamp foundation pipeline in order to facilitate the fabrication of the street lamp foundation and the installation of electric wires, and to prevent foreign matter from entering the pipeline.

The purpose is to provide a foundation box that is easy to manufacture street lamp pole foundation and wire insertion work.

In order to achieve the above object of the present invention, the basic box according to an embodiment of the present invention

A passage through which an external electric wire can enter the street lamp is formed and includes a cover formed to cover a box and a box formed so that a part or the whole of the upper part of the passage is opened;

A conduit connector configured to connect the outer conduit and the vox,

It includes a bolt fixing portion formed to be inserted and fixed to the base bolt screwed with the nut.
