Description

[0001] PREFABRICATED ROOF DRAIN [0002]

In particular, the present invention relates to a prefabricated loop drain, and more particularly, to a method of connecting a flange to a lower body by selectively connecting a top surface or a bottom surface of a flange connection portion to a lower body connection portion to extend a height of the loop drain by a predetermined length To a prefabricated loop drain.

The conventional loop drain uses only the joint ring as a means for extending the length. However, since the joint ring is joined by the simple fitting of the upper and lower bodies or the plurality of joint rings and the upper body, There is a problem that the use of the ring is necessary and the cost of the material is increased due to the necessity of the ring for the extension.

In addition, the conventional loop drain has a problem that water vapor leaks to the side through the connection portion when the lower body and the sleeve are connected.

On the other hand, as a prior art related to the loop drain, there is a Korean Registered Utility Model No. 20-0413820 (registered April 05, 2006, Loop Drain).

In this patent document, "a body made of a hollow connection portion coupled to the upper end of a drain pipe into which sewage and rainwater on the roof slab flows, and a flange portion buried in an exposed upper surface of the slab layer, A loop drain comprising a drain cap formed with a plurality of drain holes, wherein the body is provided with a depression for receiving the lower end of the drain cap around the inner circumference of the upper end of the connection part. When the drain cap is seated on the depression, And the upper end of the drain hole and the depression are positioned coaxially or lowerly with the upper surface of the flange portion so as to prevent the flow of the rainwater from being blocked.

However, in the conventional loop drain such as the patent literature, the method of extending the length of the loop drain itself by using the flange without using a joint ring is not disclosed at all due to the structure of the flange, and the leakage of water vapor to the side Respectively.
