Description

Dry hot water ondol panel {dry hot water ondol panel}

The present invention relates to a dry hot water ondol panel in which the rail protrusion fitted into the hose receiving groove of the lower panel is integrated with the lower panel by injection molding.

In the conventional prefabricated ondol panel, a hot water hose is accommodated in a U-shaped hose receiving groove formed on the upper surface of the lower panel (floor panel), and a pair of supports of a heat dissipation bracket are inserted into the inside of the U-shaped hose receiving groove to form a heat dissipation bracket. The installation prevents the flow of the hot water hose and transfers the heat of the hot water hose to the upper part to be dissipated. Then, a steel plate is laid on the lower panel, and floor finishing materials (flooring, tiles, reinforced floor, hard floor, etc.) are laid on the steel plate to complete the construction. Steel plates and heat dissipation brackets are manufactured from metals with excellent thermal conductivity, such as aluminum.

On the other hand, the U-shaped hose receiving groove may be configured as a semicircular hose receiving groove, but in the case of a semicircular hose receiving groove, a part of the hose is exposed to the outside, so when the hose is laid in a zigzag S shape, it deviates upward especially when switching. There is a high risk of damage, so constructability is very poor so do not use it.

These conventional prefabricated temperature panels have the following problems.

First, because the steel plate and heat dissipation bracket are separated, two-time construction may be required by inserting multiple heat dissipation brackets one by one and then laying a steel plate on top of them.

Second, the supports of multiple heat dissipation brackets are fitted only into straight U-shaped grooves, and there is no heat transfer structure in the curved U-shaped groove, so the heat dissipation effect may be very low.

Third, because multiple heat dissipation brackets must be individually inserted into straight U-shaped grooves, construction time can take a very long time.

Fourth, since the steel plate and heat dissipation bracket are made of aluminum, they can be relatively expensive and heavy.

Fifth, when it is necessary to drive anchors or nails into the floor while a steel plate is laid, the position of the hose cannot be confirmed from the outside, so the steel plate at the position to be driven is lifted, the position of the hose laid is checked, and the position of the hose is roughly marked on the steel plate. Having to reinstall it later can be quite a hassle.
