Description

Draining Plate Assembly {Draining Plate Assembly}

The present invention relates to a drain plate assembly, and more particularly, to a drain plate assembly capable of improving adhesion with a foundation concrete layer.

In general, the drainage plate is for waterproofing and for treating the infiltration of underground structures, and is installed between the foundation concrete and the upper protective concrete to prevent moisture, condensation and leakage of the basement floor.

These drainage plates are installed in basement structures, underground constant temperature and humidity rooms, underground bunkers, relics exhibition rooms and storages, tunnels, subways, swimming pools, underground parking lots, electrical rooms, machine rooms, etc. to prevent imperfect underground waterproofing defects. When replacing, it reduces the amount of underground excavation and residual soil processing, thereby reducing the construction period and cost.

Republic of Korea Patent Registration No. 10-0679480 discloses a drainage plate and a basement floor construction method using the same. The disclosed drainage plate has a plurality of support pillars protruding from one side of a flat plate at regular intervals, and has an opening formed so that concrete is discharged to the lower end of the support pillar.

This drain plate blocks the space formed by the drain plate as concrete flows in between the foundation concrete and the upper protective concrete, so that drainage is not performed smoothly, and furthermore, the function of preventing condensation and moisture in the basement layer is relatively deteriorated. In addition, the strength of the support column is weakened, and the drainage plate may be depressed by the surcharge load (manpower load and laying material load for upper concrete casting).

Korean Utility Model Registration No. 20-0311092 discloses a drainage and moisture barrier. Disclosed drainage and damp-proof plate has upper projections protruding at regular intervals on the upper part of the drainage body, and an inlet hole is formed through one side of the upper projection to be connected to the lower part of the drainage body to have air permeability for dehumidification.

And Korean Utility Model Registration No. 20-0383509 discloses a drain plate for preventing condensation. Disclosed is a drain plate for preventing condensation comprising a lower drain plate having an empty space therein and having a plurality of lower support pillars formed with openings at ends thereof, and a heat insulating material on the lower drain plate and a plurality of upper support pillars between the lower support pillars. It is attached and the shape of the drainage plate is formed to have an egg plate shape.

As described above, the upper protective concrete is installed on the upper side of the drain plate to cut off between the foundation concrete and the upper protective concrete, so if the surface of the foundation concrete is not smooth, the end of the support column of the drainage plate does not come into contact with the upper surface of the foundation concrete. There is a problem that is not suspended. It must have strength greater than the standard value to prevent the drain plate from sinking or being damaged due to manpower and facility load for upper concrete pouring on the drain plate. Therefore, it is not easily deformed (not deformed because it is not flexible) by the load of the upper concrete, and the end of the support column is suspended.

In this way, when a relatively large repetitive load (vehicle and manpower load) is applied to the upper foundation concrete when the end of the support column is not in contact with the upper surface of the foundation concrete, differential settlement and cracks occur or are damaged in the upper foundation concrete layer. there is In such a crack, when the water of the collecting well flows back or there is a large amount of leachate, water accumulates on the upper part of the foundation concrete layer, and this water flows back to the cracked part. In addition, when a repeated load is applied to the surrounding normal upper foundation concrete, this crack causes additional soft cracks in the surrounding concrete layer, and furthermore, leads to serious defects.

In order to solve these problems, drainage plates or drainage assemblies of various structures are being developed, and structures with improved adhesion to foundation concrete and construction efficiency are continuously required.
