The present invention relates to a double floor structure for building floors, and more particularly to a double floor structure that can increase the temperature of the air blown out to the floor in the room.

The indoor heating method is largely divided into a method of radiant floor heating using ondol, and a method of heating by introducing heating air. Floor radiant heating is mainly used to heat relatively small indoor spaces such as apartments or houses, and heating by inlet air is used to heat commercial buildings such as buildings.

However, in the case of floor radiant heating, there is an advantage that the comfort of the occupants is very excellent, and in recent years, buildings that adopt floor radiant heating have been increasing. In order to perform the bottom radiant heating, conventionally, the hot slab is arranged in a bottom slab in a zigzag shape, and a wet ondol structure is then embedded in the hot slab using mortar. However, the wet ondol structure has a difficulty in crushing mortar during repair or remodeling after construction.

In order to solve the above problem, techniques related to a double floor structure using a floor panel have recently been developed. The double floor structure has excellent construction convenience and water retention, but does not effectively utilize floor space, and has a relatively small amount of heat storage.

An object of the present invention is to increase the thermal comfort of an indoor space by increasing the temperature of the air blown out from the floor of the room.

The present invention is disposed spaced apart from the floor slab, and includes a heating pipe therein, at least two are arranged between the floor panels, and the floor slab and the floor panels are disposed, and is introduced from the outside and taken out into the building interior It provides a double-bottom structure including an air supply heating device for exchanging the air to be heated with the heating water flowing into the heating pipes.

In the present invention, the air supply heating device, a duct defining a space in which the outside air flows, in contact with the outside air in the duct, one side is connected to the outlet of the heating pipe of the one floor panel, The other side may include a water pipe connected to the inlet of the heating pipe of the other bottom panel.

In this case, fins may be formed in the water pipe portion in contact with the outside air.

In addition, in the present invention, the outside air whose temperature is raised by the air supply heating device may be blown out of the indoor lower floor adjacent to the outer wall window of the building.

Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 to 3, there is shown a double bottom structure in accordance with one embodiment of the present invention. FIG. 1 is a schematic cross-sectional view of a double bottom structure, and FIG. 2 is a schematic layout view of the floor panels 100, the air supply heating apparatuses 200, and the outlets 184 shown in FIG. 1. 3 is a perspective view of the air supply heating device shown in FIG. 1.

Referring to FIG. 1, support members 170 are disposed on a floor slab 200 of a building. Lower ends of the respective support members 170 are fixed to the bottom slab 50, and the bottom panels 100 are seated on the upper ends. Each support member 170 serves to support the bottom panels 100 to be spaced apart from the bottom slab 50. In order to support stably, it is preferable that the plurality of support members 170 support one bottom panel 100.

Referring to FIG. 2, the bottom panels 100 are supported by the support members 170, and a plurality of bottom panels 100 are continuously arranged to form an indoor floor surface. For ease of manufacture, the bottom panels 100 have substantially the same shape, but may have different shapes.

Each floor panel 100 includes a heating pipe 180 therein. The heating pipe 180 is formed using an Excel pipe or a copper pipe, and heats the room while the heating water flows into the heating pipe 180. The heating pipe 180 extends in a zigzag direction in each of the bottom panels 100.

Each floor panel 100 further includes a seating member 185 on which the heating pipe is mounted. The seating member 185 is generally formed of a urethane foam layer, and a moistureproof member (not shown) or a heat insulating member (not shown) may be further disposed on a lower surface of the urethane foam layer. In addition, a heat sink (not shown) may be disposed on the seating member 185 for effective diffusion of heat transferred from the heating pipe 180.

The bottom finisher 190 is disposed on the upper surface of the bottom panels 100. The floor finishing material 190 is disposed over the entire interior floor, and is formed using various materials such as synthetic resin.

Referring to FIG. 1, an air supply heating device 200 is disposed between the bottom panels 100 and the bottom slab 50. The air supply heating device 200 increases the temperature of the low-temperature air introduced from the outside by using the high temperature heating water introduced into the heating pipe 180.

Referring to FIG. 3, each air supply heating device 200 includes a duct 220 defining a space in which external air flows, and a water pipe 210 in contact with the external air in the duct 220. One side 210a of the water pipe is connected to the outlet 180a of the heating pipe of the one bottom panel, and the other side 210b is connected to an inlet (not shown) of the heating pipe of the other bottom panel. This will be described in detail as follows. The heating pipe 180 of one floor panel is connected to the heating pipe of another adjacent floor panel so that the heating pipes are connected as a whole. In addition, each air supply heating device 200 is disposed between the heating pipes 180 connected to each other. Therefore, the heating water flowing out from the heating pipe 180 for one floor panel passes through the air supply heating device 200 and then flows into the heating pipe 180 for the other floor panel. However, not all heating pipes are directly connected to the air supply heating device, and only some heating pipes may be connected to the air supply heating device. The water pipe 210 may be directly connected to the heating pipe 180, or may be formed using the connection pipes 230 and 240. Excel pipes and heat pipes may be used as the connection pipes 230 and 240, and a pipe of rubber material having excellent flexibility may be used.

Fins 215 are formed outside the water pipe 210. The fins 215 serve to increase the heat transfer area, thereby improving the heat transfer rate between the heating water and the outside air. Referring to FIG. 3, the pins 215 have an annular type, but pins of various shapes may be formed.

1 and 3, the duct 220 includes a main body portion 221 in which a water pipe is disposed, an enlarged portion 222 disposed in front of the main body portion 221, and a reduction portion disposed in a rear end of the main body portion. 223. The enlarged portion 222 increases the turbulent component of the outside air, thereby increasing heat transfer between the outside air and the heating water. In addition, the reduction unit 223 increases the flow rate of the air whose temperature is raised, thereby functioning to smooth the flow of air.

The duct 220 further includes a first connector 224 connecting the enlarged portion 222 and the external duct 260 for introducing external air. The outer duct 260 may extend directly outside, but is preferably connected with a waste heat recovery device (not shown). If the external duct 260 is connected to the waste heat recovery device, since the outside air is introduced into the air supply heating device 200 after the temperature is primarily raised in the waste heat recovery device, the air is blown out into the room 70. It can further increase the temperature of.

In addition, the duct 220 further includes a second connection part 225 connecting the reduction part 223 and the indoor outlet part 270. The indoor blower 270 is connected to the blower outlet 184 disposed on the indoor floor, and a guide vane 275 is formed therein, so that the blown air smoothly flows into the indoor space 70. The outlet 184 may be arranged in a variety of locations, but in order to reduce cold draft, as shown in FIG. 1, the outlet 184 is located in the lower floor of the room adjacent to the window 80 installed in the outer wall 60 of the building. Preferably disposed.

The double bottom structure according to the present invention has the following effects.

First, since hot air can be blown out from the indoor floor into the room, the thermal comfort of the occupants is increased because the temperature of the indoor air increases.

Second, since hot air can be blown out of the interior floor adjacent to the exterior window of the building, cold drafts and condensation on the window can be prevented in winter. In particular, when the balcony of the building has an extended structure, it is more effective in preventing cold drafts and condensation in winter.

Third, when the exhaust duct for exhausting the indoor space on the ceiling, it is possible to have a structure that blows air from the floor and exhausts the air from the ceiling. In this case, since efficient ventilation is possible, indoor air cleanliness increases. In addition, since it can be formed in a dry ondol method, the concrete curing period is unnecessary, and the construction time can be shortened. In addition, since the space between the floor panels and the floor slab can be used, electrical equipment or the like that is generally installed in the ceiling can be arranged, thereby reducing the ceiling space.

Fourth, in summer, since the air can be blown out to the indoor floor without heating the air in the air supply heating device, it is possible to cool the room by using the low temperature floor heat storage.

Although the present invention has been described with reference to the embodiments shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible. Therefore, the true technical protection scope of the present invention will be defined by the technical spirit of the appended claims.
