The present invention relates to a drain plate for preventing condensation, and more particularly, to a drain plate for preventing moisture condensation and leakage in the basement layer by forming a drainage path between a foundation concrete and an upper protective concrete of a building.

In general, the drainage plate is installed between the base concrete and the upper protective concrete as a device for treating the infiltration water of the underground structure for waterproofing, to prevent moisture, condensation and leakage of the underground layer. These drain boards are installed in underground structures, underground constant temperature and humidity rooms, underground bunkers, relics and storage rooms, tunnels, subways, swimming pools, underground parking lots, electric rooms, and machine rooms to prevent incomplete underground waterproof defects. In case of replacement, it can reduce construction period and construction cost by reducing underground digging and residual soil treatment.

Korean Patent Laid-Open Publication No. 2005-0110305 discloses a drainage plate and a method for constructing a basement floor using the same. The disclosed drainage plate is formed with a plurality of support pillars protruding to one side of the plate at regular intervals, and has a configuration in which openings are formed so that concrete is discharged to the lower end of the support pillar.

Such a drain plate prevents concrete from flowing into the space between the foundation concrete and the upper protective concrete to block the space formed by the drain plate, thereby preventing drainage smoothly, and further reducing the dew condensation and moisture protection of the basement layer.

Registered Utility Model No. 0311092 discloses a drainage damper plate. The disclosed drainage moistureproof plate is formed to project the upper protrusions at a predetermined interval on the upper portion of the drainage body, and the inflow hole is connected to the lower portion of the drainage body at one side of the upper protrusion in order to have breathability for moisture proofing.

In addition, registered utility model No. 0383509 discloses a condensation preventing drain board. The disclosed condensation preventing drainage plate includes a lower drainage plate having a plurality of lower support pillars having an empty space therein and having an opening portion at an end thereof, and a plurality of upper support pillars between the lower support pillars with a heat insulating material on the lower drainage plate. It is attached so that the shape of the drain board may have an egg plate shape.

As the upper protective concrete is installed on the upper side of the drainage plate as described above, the base concrete and the upper protective concrete are disconnected. Therefore, when the surface of the foundation concrete is not smooth, the end of the support pillar of the drainage plate does not contact the upper surface of the foundation concrete. There is a problem that is suspended. As such, when the end of the support pillar is not in contact with the upper surface of the base concrete, there is a problem in that an uneven settlement and crack occurs or breaks in the upper protective concrete layer when a relatively large load is applied to the upper protective concrete. Such cracking causes water to accumulate in the upper part of the foundation concrete layer when the water of the sump flows back, and this water flows back to the cracked portion. This crack also causes additional cracks due to repeated loads on the surrounding top protective concrete, leading to serious defects.

The present invention can fundamentally prevent the end of the drain plate support pillars from contacting the upper surface of the foundation concrete layer due to the unevenness of the upper surface of the foundation concrete layer in order to solve the problems as described above. An object of the present invention is to provide a condensation preventing drain plate that can prevent cracks from occurring.
