METHOD OF BASEMENT FLOOR CONSTRUCTION USING ANTI-DEWING DRAIN BOARD

摘要

The present invention relates to a basement floor construction method using a condensation prevention drainage plate, by using a plurality of support pillars protruding at regular intervals on both sides by installing an egg plate-shaped drainage plate on the top of a bottom spherical concrete that is not flat. Even though the groundwater discharged to the top through the bottom concrete layer installed below the drainage plate or flowed back from the sump is filled to the lower surface of the drainage plate, the drainage plate is kept warm and insulated by the air layer formed on the upper support column of the drainage plate. Condensation, moisture, or water leakage may be prevented on the pressed concrete layer placed on the upper portion of the condensate.;Basement floor construction method using a condensation prevention drainage plate according to the present invention for implementing this step comprises the steps of forming a cast concrete layer to a predetermined height on the gulto finish surface; Forming a bottom spherical concrete layer at a predetermined height on the discarded concrete layer; On the bottom concrete layer, a plurality of upper support pillars and lower support pillars are formed to protrude in an egg plate shape, and a drain plate having an air insulation layer of an empty space is formed inside the upper support pillar, but is introduced into the lower portion of the drain plate. Installing the groundwater to be drained to the sump and the trench connected to the sump; And forming a pressed concrete layer at a predetermined height on the drain plate.;Drain board, dew condensation, thermal insulation material, drainage channel, support column
