PREFABRICATION TYPE FLOOR HEATING SYSTEM AND THE CONSTRUCTION METHOD THEREOF

[Technical Field]

The present invention relates to a prefabrication type floor heating system and a method for constructing the same, and more particularly to a prefabrication type floor heating system and a method for constructing the same, which allow housing heating elements to be easily constructed, i.e., to be easily manufactured, prefabricated, partially repaired, checked, and broken up, so as to shorten a construction time, and improve a heating efficiency for transferring heat to an indoor floor, suppress the generation of noise between floors by absorbing sound, and have adiabatic and soundproof effects.

[Background Art]

In general, in order to heat an indoor room, a method, in which a heat insulator is spread on a subfloor in the room, hot water pipes, such as synthetic resin pipes (referred to as "XL pipes") or copper pipes, are disposed in zigzags on the heat insulator, a fine aggregate, such as gravel or sand, fills spaces between the neighboring hot water pipes to the same height as that of the hot water pipes, and mortar is applied to the upper surfaces of the hot water pipes and the fine aggregate, was conventionally mainly used.

The above construction method has a complicated process and requires a long time to harden the mortar before a next work is started, thereby causing a high construction cost, lengthening a construction period, and thus lowering the competitive power in construction. Further, the hot water pipes are separated from each other but are made of a single material, thermal conduction is uniform in all

directions, and energy storage or loss occurs at the neighboring portions. Pure heat used to heat the room or adjust the indoor temperature should pass through the mortar, i.e., a medium having a very low conductivity, so as to be applied for the purpose of heating the room. Thus, the above construction method requires a long time to heat the room, and has a low thermal efficiency.

In order to solve the above problems partially, a method, in which prefabrication type upper and lower panels for housing hot water pipes are constructed instead of the construction of mortar, was proposed. In this case, a subfloor of a structure is not leveled entirely, and thus in order to employ this method, the subfloor should be leveled before the method is started. Therefore, this method requires a separate cost to level the subfloor. Further, since the strength of the panels is not so high, a countermeasure to reinforce the strength of the panels should be considered. Moreover, this method still has problems caused by low thermal conductivity, and thus cannot be practically used. Moreover, Korean Patent Registration No. 10-0402205 discloses "Radiant floor heating system without pipe". Such a system uses floor panels, to be constructed, in place of hot water circulation pipes, thus being constructed without any pipe. On the other hand, in order to employ this system, a subfloor of a structure should be leveled. However, since the subfloor is not leveled substantially, the system is constructed after the subfloor is leveled. Further, the system cannot have any countermeasure to reduce noise between floors.

[Disclosure] [Technical Problem]

Therefore, the present invention has been made in view of the above problems, and it is an object of the present invention to provide a prefabrication type floor heating system and a method for constructing the same, in which the system is easily constructed, a construction time is shortened, and a heating efficiency is improved.

It is another object of the present invention to provide a prefabrication

type floor heating system and a method for constructing the same, in which the leveled state of a subfloor in a structure is maintained by adjusting the heights of respective portions of the system even when the height of the subfloor is not uniform. It is another object of the present invention to provide a prefabrication type floor heating system and a method for constructing the same, in which the generation of noise between floors is reduced, and if noise is generated, the noise is absorbed or excluded.

It is yet another object of the present invention to provide a prefabrication type floor heating system and a method for constructing the same, in which spaces between a subfloor and lower members are used as utility spaces, such as working holes or utility-pipe conduits, in which various pipes and power lines are arranged.

[Technical Solution]

In accordance with an aspect of the present invention, the above and other objects can be accomplished by the provision of a prefabrication type floor heating system comprising level controlling members installed on a subfloor and having a height adjusting function for maintaining a leveled state of the system; lower members connected with the level controlling members, separated from the subfloor and supported under the condition that a space is formed between the subfloor and the lower members, provided with pipe grooves for receiving heating medium pipes, and installed so as to maintain their leveled state; the heating medium pipes fitted into the pipe grooves of the lower members; upper members located on the lower members, and provided with pipe grooves for receiving the heating medium pipes; and a soundproof insulating member filling the space between the subfloor and the lower members.

The prefabrication type floor heating system may further comprise heat storage members, each of which is installed under the heating medium pipes between the corresponding upper and lower members.

Utility spaces may be secured in advance in the space between the

subfloor and the lower members.

In accordance with another aspect of the present invention, there is provided a method for constructing a prefabrication type floor heating system, comprising constructing a plurality of lower members on the subfloor such that the leveled state of the lower members is maintained by adjusting the heights of the lower members using level controlling members connected to the lower members; constructing heating medium pipes by fitting the heating medium pipes into the upper surfaces of the lower members; connecting upper members to the lower members and fixedly installing the level controlling members under the condition that the heating medium pipes are fitted into the upper surfaces of the lower members; and constructing a soundproof insulating member in a space between the subfloor and the lower members by filling the space with an expanded resin having excellent soundproof and adiabatic effects.

In the construction of the heating medium pipes, heat storage members may be connected to the upper surfaces of the lower members, and then the heating medium pipes may be fitted into the upper surfaces of the heat storage members.

[Advantageous Effects]

The present invention provides a prefabrication type floor heating system and a method for constructing the same, in which lower members are first constructed such that the entirely leveled state of the lower members is maintained using level controlling members, heating medium pipes including heat storage members are constructed on the lower members, upper members are constructed, and then a soundproof insulating member is constructed, thus simplifying a construction process, shortening a construction time, and improving a heating efficiency due to the use of the soundproof insulating member.

Further, even when the height of the subfloor inside a structure is not leveled, the prefabrication type floor heating system of the present invention maintains a leveled state by adjusting the heights of respective portions using the level controlling members. Anti-vibration cushion members of the level

controlling members serves to absorb impact with the subfloor and reduce the transfer of the impact downwardly after the prefabrication type floor heating system is constructed, and the soundproof insulating member prevents the transfer of noise between floors. Utility spaces are secured in a space between the subfloor and the lower members during construction, thus being used as working holes or utility-pipe conduits, in which various pipes and power lines are arranged. Therefore, the prefabrication type floor heating system of the present invention is discriminated from conventional floor heating systems, and has the accompanying effects, thus being used for multiple purposes.

Further, the prefabrication type floor heating system of the present invention may further includes separate heat storage members 3, each of which is installed under the heating medium pipes 4 between the corresponding lower and upper members 2 and 5.

Each of the level controlling members 1 includes a screw member 10, an anti-vibration cushion member 12 connected to the lower end of the screw member 10, a lower nut 16 screw-connected to the lower part of the screw member 10 for adjusting the height of the corresponding lower member 2 so as to maintain the leveled state of the lower members 2, and an upper nut 14 screw-connected to the upper part of the screw member 10 so as to fix the upper and lower members 2 and 5 to each other.

The anti -vibration cushion member 12 serves to absorb impact with the subfloor, reduce the transfer of the impact downwardly, and cause the lower member 2 to be separated from the subfloor by the level controlling member 1, after the prefabrication type floor heating system is constructed, thus preventing the transfer of noise between floors.

The lower members 2 are manufactured in the form of precast concrete or an injection molded product made of synthetic resin, as shown in FIGS. 2 and 6, or are manufactured by press molding a metal plate, such as an iron plate, as shown in FIG. 7. The lower members 2 are provided with a plurality of connection holes 20, into which the level controlling members 1 are inserted, formed therethrough, and the pipe grooves 22 formed in the upper surfaces thereof for receiving the heating medium pipes 4.

Here, the pipe grooves 22 of the lower member 2, on which the heat storage member 3 is provided, have a lager size than that of the pipe grooves 32 of the heat storage member 3 so that the pipe grooves 32 can be fitted into the pipe grooves

22.

Further, a conventional paper floor may be used as the surface finishing member 7.

[Mode for Invention]

Hereinafter, a method for constructing the above prefabrication type floor heating system of the present invention will be described.

The method for constructing the prefabrication type floor heating system of the present invention includes a first step of constructing a plurality of the lower members 2 on the subfloor such that the leveled state of the lower members 2 is maintained by adjusting the heights of the lower members 2 using the level controlling members 1 connected to the lower members 2, a second step of constructing the heating medium pipes 4 by fitting the heating medium pipes 4 into the upper surfaces of the lower members 2, a third step of connecting the upper members 5 to the lower members 2 and fixedly installing the level controlling

members 1 under the condition that the heating medium pipes 4 are fitted into the upper surfaces of the lower members 2, and a fourth step of filling the space between the subfloor and the lower members 2 with the soundproof insulating member 6 by foaming a resin having excellent soundproof and adiabatic effects. Now, the method will be sequentially described in detail.

First step (Construction of lower members while maintaining leveled state)

The lower members 2 are constructed on the subfloor such that the leveled state of the lower members 2 is maintained by adjusting the heights of the lower members 2 using the level controlling members 1 connected to the lower members 2. The screw members 10 of the level controlling members 1 are respectively inserted into the connection holes 20 of the lower members 2 under the condition that the lower nuts 16 are located at proper positions of the screw members 10, and the lower nuts 16 are adjusted so as to control the mounting positions and heights of the lower members 2. Here, the leveled state of the lower members 2 is maintained by adjusting the lower nuts 16 according to the condition of the subfloor.

Second step ( ^" Construction of heating medium pipes)

The heating medium pipes 4 are fitted into the upper surfaces of the lower members 2. The heating medium pipes 4, such as XL pipes or other various pipes used for heating media, are fitted into the pipe grooves 22 of the lower members 2. As shown in FIG. 2, the heating medium pipes 4 are constructed on the overall upper surfaces of the lower members 2.

In the case that the heat storage members 3 are employed, the heat storage members 3 are installed on the upper surfaces of the lower members 2 before the heating medium pipes 4 are constructed. Here, the heating medium pipes 4 are fitted into the pipe grooves 32 of the heat storage members 3 under the condition that the level controlling members 1 are inserted into the connection holes 30 and the pipe grooves 32 are fitted into the pipe grooves 22 of the lower members 2.

Third step (Connection of upper members to lower members)

The upper members 5 are connected to the upper surfaces of the lower members 2 and the level controlling members 1 are fixedly installed under the condition that the heating medium pipes 4 are connected to the lower members 2.

The upper portions of the heating medium pipes 4 are fitted into the pipe grooves 52 of the upper members 5, and the screw members 10 of the level controlling members 1 are inserted into the connection holes 50 of the upper members 5. Then, the upper nuts 14 are screw-connected to the connection holes 50, and the closing caps 56 are connected to the opening grooves 54, into which the upper nuts 14 are inserted, thereby connecting the upper and lower members 5 and 2, the heating medium pipes 4, and the level controlling members 1. In the case that the heat storage members 3 are employed, the heat storage members 3 are connected to other elements also. Fourth step (Construction of soundproof insulating member)

The space between the subfloor and the lower members 2 is filled with the soundproof insulating member 6 by foaming a resin having excellent soundproof and adiabatic effects. An expanded resin, including polyurethane, fills the space between the subfloor and the lower members 2 under the condition that the upper and lower members 5 and 2, the heating medium pipes 4, the level controlling members 1, and the heat storage members 3 are connected, thus constructing the soundproof insulating member 6. The soundproof insulating member 6 intercepts heat generated from the heating medium pipes 4 so as to improve thermal efficiency, and excludes noise generated from the upper parts of the upper members 5 or the surface finishing member 7 so as to improve a soundproof effect. Before the soundproof insulating member 6 is constructed, the utility spaces (U) are secured in advance. Thus, the utility spaces (U) can be used as various working holes or utility-pipe conduits.

The prefabrication type floor heating system of the present invention is constructed through the above first to fourth steps.

After the construction of the prefabrication type floor heating system is completed, a heating operation is carried out by supplying a heating medium through the heating medium pipes 4. When the heating operation is performed, heat emitted from the heating medium pipes 4 is transferred in all directions. However, the soundproof insulating material 6, which is located below the heating medium pipes 4, intercepts the heat emitted from the heating medium pipes 4.

Therefore, most of the heat emitted from the heating medium pipes 4 is transferred upwardly, and passes through the upper members 5, thereby being used to heat a room and thus improving thermal efficiency.

Further, in the case that the heat storage members 3 are employed, the heat transfer between the heating medium pipes 4 is uniform, and the heat is uniformly emitted throughout the inside of the room, which is located above the upper members 5, thus uniformly maintaining the temperature of the floor of the room.

[Industrial Applicability]

As apparent from the above description, the present invention provides a prefabrication type floor heating system and a method for constructing the same, in which lower members are first constructed such that the entirely leveled state of the lower members is maintained using level controlling members, heating medium pipes including heat storage members are constructed on the lower members, upper members are constructed, and then a soundproof insulating member is constructed, thus simplifying a construction process, shortening a construction time, and improving a heating efficiency due to the use of the soundproof insulating member.

Although the preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
