CONSTRUCTION METHOD OF VENT PIPE IN PARKING AREA ON ROOF FLOOR

摘要

PURPOSE: A ventilation construction method in a roof parking lot is provided to prevent debonding and segregation defects of a waterproof layer by discharging moisture generated in a waterproof bottom surface and waterproof layer and to enhance a waterproof structure and the durability of a building by maintaining a dried state. CONSTITUTION: A ventilation construction method in a roof parking lot is as follows. A bottom surface of a roof where a waterproof layer is arranged is cleaned. A position where a set anchor is installed is marked, and a ventilation pipe is prepared to be installed. The set anchor is installed to set a car stopper. The ventilation pip is installed in the middle of a marked position of the car stopper. A primer layer is formed by spraying primer. A fiber sheet layer is formed by paving a fiber sheet up to a steam lead-in surface of the ventilation pipe. A primary waterproof layer is formed to fully fill into a hole of the fiber sheet, thereby being integrated with the fiber sheet. A stiffening tape is pasted in a wall and corner. A second waterproof layer reinforcing the primary waterproof layer and acting as an elastic waterproof layer is formed. A durable coating layer is formed after hardening the second waterproof layer. A top coating layer is formed on the durable coating layer. The car stopper is fixed on the set anchor after hardening the top coating layer. Surrounding is cleaned and waterproof work is ended. Traffic is opened after lining a parking line.
