COMBINER FOR DUCT MAINTENANCE AND DUCT MAINTENANCE COMBINATION STRUCTURE

摘要

The present invention relates to a combiner for duct maintenance and a duct maintenance combination structure. To this end, the combiner is combined with the lower part of a damaged old manifold installed in a duct. A through hole is formed in the lower part of a curved pressurizing panel, the lower part of an upward inclined hollow guide pipe is combined with the through hole, a bolt through hole is formed on the edge of the pressurizing panel, and the inner surface of a gasket touches the outer surface of the pressurizing panel. As such, the present invention is capable of reducing hours and costs for work while reducing the number of workers by maintaining a new manifold inside the duct without digging the ground around the duct and the old manifold.;COPYRIGHT KIPO 2017
