On the other hand, the cylinder may be directly buried in the ground, but most of them form an installation hole in the concrete surface by a boring machine (boring machine) and then insert it into the epoxy resin, etc., a fixing means between the installation hole and the outer surface of the cylinder. It is injected to fix it.

However, the conventional joint box described above has a problem that the weight and weight of the metal material is very heavy, and therefore, the transportation and purchase operation is quite cumbersome, as well as the corrosion is made in a short time, and the material value is quite expensive.

In addition, in order to prevent fluidity after embedding in the installation hole of the ground or in particular concrete surface, the epoxy resin, which is a fixing means, is injected between the cylinders, and the bonding force between the surface of the cylinder, which is a metal material, and the epoxy resin is not firmly fixed. I also had a problem.

In addition, when the runway guide light is coupled to the flange of the joint box, there is also a cumbersome problem of providing a separate sealing means in order to prevent rain water or moisture from entering.

And, first of all, there is a problem in that the soil around the runway due to zinc contained in the alloy component is significantly degraded.

Accordingly, the present invention has been made to solve the conventional problems as described above, the purpose is to prevent corrosion and at the same time more securely secured at the time of purchase, to prevent soil contamination of the buried area, The present invention provides a joint box for a runway induction lamp that has a greater response force to a load applied therefrom and also prevents water from entering therein.

At the same time, it will have the effect of preventing soil pollution in the area purchased.

In addition, by fixing the epoxy resin in the installation hole by the reinforcement / fixing part formed in the joint box has a greater fixing force, as well as a greater response to the load applied from the top by the reinforcing protrusion formed therein. Therefore, it is to have the effect of minimizing deformation or breakage after embedding.

In addition, by the hermetic ring formed on the flange portion, water such as rain water can be prevented from entering into the inside, and various parts in the joint box can be prevented from being damaged due to corrosion or the like.

In addition, by allowing the drainage portion formed on the bottom surface of the joint box to smoothly discharge the water generated by the internal temperature change, it also has the effect of minimizing damage to the components in the joint box.

In addition, by forming a plurality of support legs in which the height adjustment is formed on the bottom surface of the joint box body in which the drainage part is formed, when the joint box is loaded with the effect that it is easier to load due to the flange portion and the plurality of support legs. Even when the bottom surface of the installation hole is uneven, by adjusting the height adjustment part to maintain the joint box in a horizontal state has an effect that can be made easier embedding work.

Moreover, by providing an auxiliary embedding body in the upper part of the main body of a joint box, it also has the effect of being able to embed easily in the required depth irrespective of a embedding condition.
