Description

Draining Plate Assembly

The present invention relates to a drain plate assembly, and more specifically, to a drain plate assembly that can improve adhesion to the foundation concrete layer.

In general, drain plates are used for waterproofing and treatment of seepage water in underground structures, and are installed between the foundation concrete and the upper protective concrete to prevent moisture, condensation, and water leakage in the basement floor.

These drain plates are installed in underground structures, underground temperature and humidity rooms, underground bunkers, relic exhibition halls and storage rooms, tunnels, subways, swimming pools, underground parking lots, electrical rooms, and mechanical rooms, etc. to prevent imperfect waterproofing defects in the basement in advance, and use the double slab construction method. When replacing, it reduces the amount of underground excavation and residual soil disposal, thereby reducing the construction period and cost.

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

In such a drain plate, concrete flows between the foundation concrete and the upper protective concrete, blocking the space formed by the drain plate, preventing smooth drainage, and further deteriorating the condensation and moisture prevention function of the basement floor. Additionally, the strength of the support column may be weakened, causing the drainage plate to cave in due to the overburden load (manpower load and laying material load for pouring the upper concrete).

Republic of Korea Registered Utility Model Publication No. 20-0311092 discloses a drainage moisture barrier plate. The disclosed drainage moisture barrier plate has upper protrusions protruding at regular intervals on the upper part of the drainage main body, and an inlet hole is formed through one side of the upper protrusion to be connected to the lower part of the drainage main body in order to have breathability for moisture prevention.

And in Korea Registered Utility Model Publication No. 20-0383509, a drain plate for preventing condensation is disclosed. The disclosed condensation prevention drain plate includes a lower drain plate having a plurality of lower support pillars with an empty space inside and an opening formed at an end thereof, a heat insulating material on the lower drain board, and a plurality of upper support pillars between the lower support pillars. It is attached so that the shape of the drain plate has the shape of an egg carton.

As described above, the upper protective concrete is constructed on the upper side of the drainage plate to disconnect the foundation concrete and the upper protective concrete. Therefore, if the surface of the foundation concrete is not smooth, the end of the support column of the drainage plate does not contact the upper surface of the foundation concrete. There is a problem with the suspension being carried out without any problems. It must have a strength exceeding the standard value to prevent the drain plate from collapsing or being damaged due to the manpower and equipment load for pouring the upper concrete on the drain plate. Therefore, the end of the support column is not easily deformed (it cannot be deformed because it is not flexible) due to the load of the upper concrete and is suspended.

In this way, when the end of the support column is not in contact with the upper surface of the foundation concrete, if a relatively large repetitive load (vehicle and manpower load) is applied to the upper foundation concrete, differential settlement and cracks may occur or be damaged in the upper foundation concrete layer. There is. These cracks cause water to accumulate in the upper part of the foundation concrete layer when water from the sump flows back or there is a lot of leachate flowing in, and this water flows back into the cracked area. In addition, repeated loads are applied to the surrounding normal upper foundation concrete, causing additional soft cracks to occur in the surrounding concrete layer due to cracks in the material, which can further lead to serious defects.

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