Description

Branch Branch Outlet Fitting System

The present invention relates to a branch pipe socket attachment device for attaching a connection pipe through a branch hole on the side of the main pipe without the use of a T pipe.

In particular, the inner washer that spans the inner surface of the branch hole is larger than the branch hole and bisects and folds. The inner washer of cylindrical shape smaller than the branch hole is vertically inserted. The packing for watertightness encloses the branch pipe and the inner washer projecting tube at the same time. It has a structure of separate tubular packing.If the branch hole is bigger than the standard, use the folding inner washer and if the hole is cut with the hole cutter, use the cylindrical inner washer. It becomes a one-touch fastening branch pipe socket attachment device where watertightness is simultaneously performed. In addition, if a part of the periphery of the end of the branch hole is damaged and the hole is enlarged by the pipe and the hole cutter deformed by earth pressure or the like, a donut type reinforcement washer larger than the diameter of the branch hole may be additionally disposed between the upper surface of the cylindrical inner washer and the lower surface of the tubular packing. It is possible to make a watertight seal in three places, such as a branch hole, a periphery of the end, and a periphery of the inner surface of a pipe, and the branch pipe cannot be pulled out of the branch hole.

Japanese Patent Registration No. 3415900, Japanese Patent Application Laid-Open No. 6-207697, Japanese Patent Application Laid-Open No. 7-332567, Korean Patent Registration No. 0772712, and Korean Patent Application No. 10-2004-0075290 filed by the applicant. .

Japanese Patent Registration No. 3415900 and Korean Patent Registration No. 0772712 have a tubular packing bottom surface sliding on a tapered curved surface on a curved blade having an outward curved blade at the lower end of the main body with an inclined taper on the upper surface which is slightly less than or equal to the branch hole diameter. Since the structure of attaching the branch pipe to the packing diameter and the branch hole with one fastening nut in the structure to be expanded diameter, there is a problem in that the packing material is a soft packing material for the watertightness and preferably a hard packing material so as not to be pulled out of the branch hole.

In addition, when a part of the periphery of the end of the branch hole is damaged and the hole is enlarged by the pipe and the hole cutter deformed by earth pressure, etc., there is a problem in watertightness and the branch pipe is pulled out of the branch hole.

There is an advantage that the branch pipe can not be pulled out even if the branch hole is enlarged, but in the deformed pipe, etc., the packing is pressurized only at one inner surface of the pipe, so watertightness is not secured.

In the present invention, the inner washer while inserting a separate tubular packing vertically into the branch hole in order to solve the above-mentioned problems, the inner washer also serves as a cylindrical inner washer that is the same as or slightly smaller than the case where the outer diameter is larger than the branch hole diameter, the branch hole size is larger than the standard In case of large watertightness, if it is the same or smaller, it is vertically connected to the branching hole, and the structure to expand outwardly the tubular packing on the inside of the branching hole is larger than that of the branching hole. This is the problem to be solved.

Another task is to use a donut-type reinforcing washer larger than the diameter of the branch hole in the branch hole, the edge of the end part, and the inner peripheral part of the pipe when the part of the periphery of the branch hole is damaged and the hole is enlarged by the pipe and the hole cutter deformed by earth pressure.
