Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to floor heating that performs heating using heat transfer tubes built into the floor, and particularly relates to a heating floor finishing material that can improve heat transfer efficiency. It is.

[Conventional technology] Conventionally, in this type of floor heating, a heating panel equipped with heat transfer tubes is laid on top of the joists, etc., and then a floor finishing material is laid on top of it, thereby forming a heating floorboard. was forming.

[Problems to be Solved by the Invention] However, in the floorboards of conventional floor heating systems, if the heating panel or floor finishing material warps, a gap is created between the heating panel and the floor finishing material, causing the heating panel to warp. The disadvantage is that the efficiency of heat transfer from the floor to the floor finishing material decreases.

The present invention has been made in view of the above circumstances, and provides a heating floor finishing material that can efficiently transfer heat from heat transfer tubes to the floor finishing material even if the floor finishing material is warped. It is an object.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a floor finishing material on which back surfaces t, :, m are formed, and a material that is fitted into a groove of this floor finishing material and is elastically bonded to the groove. A heating floor finishing material comprising: heat transfer tubes fixed with an agent; a reflective material provided to cover the back side of the floor finishing material including the heat transfer tubes; and a heat insulating material laminated on the reflective material. I will provide a.

In addition, the pitch P of each heat transfer tube when the heating floor finishing material is spread over the joists, etc. is P=K×D2/tl 11.0≦K≦30.0 However, K is a constant and It is preferable that the inner diameter t of the heat tube is set to the thickness of the floor finishing material.

Here, P! =D' is in a proportional relationship with D.
2 (This is because the amount of heat transferred to the floor finishing material increases or decreases in proportion to this. In other words, the amount of heat transferred to the floor finishing material increases or decreases in proportion to D2, so the pitch of the heat transfer tubes should be increased or decreased in proportion to D2. By doing so, all heat exchanger tubes are removed from the floor covering material Z.
This is because the amount of heat transmitted becomes constant Z.

Moreover, the reason why P and t are in an inversely proportional relationship is because the amount of heat transferred from the heat transfer tube to the surface of the floor finishing material is inversely proportional to L. That is, by increasing or decreasing the pitch of the heat transfer tubes in inverse proportion to L, the amount of heat transmitted from all the heat transfer tubes to the surface of the floor finishing material becomes constant.

Furthermore, is the constant K set to II, 0 or more and 30.0 or less less than 11.0? If this setting is made, the heat exchanger tubes will be too close together, leading to overheating and making piping difficult.If it exceeds 300, the distance between the heat exchanger tubes will be too far apart, and the This is because a low-temperature area is created in the center between the heat pipe and the heat pipe.

[Function] In the present invention, the floor surface made of the floor finishing material is directly formed, for example, by spreading it over the floor joists.

Then, by connecting the ends of each heat exchanger tube with a joint or the like, all the heat exchanger tubes are brought into communication with each other.

For example, by flowing hot water through this heat transfer tube, the heat supplied by the hot water is transmitted to the floor finishing material via the heat transfer tube,
Provides floor heating. Therefore, since heat is directly transmitted from the heat transfer tube to the floor finishing material, even if the floor finishing material is warped, there is no problem in heat transfer from the heat transfer tube to the floor finishing material. Moreover, since the reflective material is provided on the back side of the floor finishing material, the heat that escapes as radiant heat to the back side is reduced, and the heat that escapes to the back side by heat conduction is also reduced because the insulation material is provided. .

In addition, since the heat transfer tubes are fixed in the grooves of the floor finishing material with an elastic adhesive, even if the heat transfer tubes and the floor finishing material expand or contract due to thermal expansion, the difference in the amount of expansion or contraction is absorbed by the elastic adhesive. This eliminates unnecessary stress on heat exchanger tubes and floor finishing materials. That is, problems such as bending of the heat transfer tubes and warping of the floor finishing material due to the difference in the amount of expansion and contraction between the heat transfer tubes and the floor finishing material are prevented.

Furthermore, the pitch P of the heat transfer tubes is P=K×D2/t1 11.0≦K≦300, where K is a constant and the inner diameter t of the heat transfer tubes is set to the thickness of the floor finishing material. , the floor surface is heated to a nearly uniform temperature with a constant amount of heat.

[Embodiment] An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

In Figures 1 to 3, l is a floor finishing material;
This floor finishing material l is a wood-based laminated material formed in the shape of a rectangular plate, with elongated protrusions 2 formed on one side in the longitudinal direction, and other floor finishings on the other side. An engagement groove 3 is formed in which the protrusion 2 of the material 1 engages. Further, the floor finishing material 1 has a finished surface 4, and two parallel grooves 6 are formed on the back surface 4 along its longitudinal direction. A heat exchanger tube 7 is inserted into the valley groove 6.

The heat exchanger tube 7 is a steel tube formed into a flat shape, and is attached with the flat direction oriented parallel to the surface 4 of the floor finishing material 1. The heat exchanger tube 7 is fixed to the valley groove 6 with an elastic adhesive.

The elastic adhesive is made of an epoxy adhesive containing a metal powder with good thermal conductivity such as copper powder, and becomes a strong elastic body that can be expanded and contracted after hardening.

Further, a reflective material 8 is provided so as to cover the back surface 5 of the floor finishing material I including the heat transfer tubes 7, and a heat insulating material 9 is laminated on the lower side of this reflective material.

The reflective material 8 is formed of aluminum foil and is bonded to the floor finishing material 1 with an elastic adhesive that does not contain metal powder.

The heat insulating material 9 is formed into a sheet shape from polyethylene foam, and is fixed to the reflective material 8 using adhesive or the like.

The heating floor finishing material configured as above is the joist IO
It is spread over the top to form the floor surface.

In this state, the pitch P between adjacent heat exchanger tubes 7 is set by the following formula.

P=K×D2/tl (1)
11.0≦K≦300 (2) However, K is a constant, the inner diameter t of the heat exchanger tube before being flattened is the thickness of the floor finishing material, and the adjacent heat exchanger tube 7 is: The ends thereof are connected by a joint 11 curved into a U-shape, resulting in zero heat exchanger tubes 7 as a whole.

The joint 11 is connected by brazing or made of a shape memory alloy.

To cover the floor with the heating floor finishing material configured as described above, the floor finishing material 1 is laid over the joists IO while fitting the protrusions 2 and the grooves 3 into each other. After fixing each floor finishing material 1 to the joists 0 with nails, etc., each heat exchanger tube 7
The ends of the two are connected with a joint 11.

Furthermore, by flowing hot water through the heat transfer tube 7, the heat from the hot water is transmitted to the surface 4 of the floor finishing material (1) via the heat transfer tube 7, and heating is performed by heat radiation from the surface 4.

According to the heating floor finishing material configured as described above, the heat transfer tubes 7 directly heat the floor finishing material I, so even if the floor finishing material I is warped, the heat transfer tubes 7 can be used to heat the floor finishing material I. The floor finishing material 1 can be heated at a constant temperature without interfering with heat transfer. Moreover, since the heat transfer tubes 7 are formed flat and the flat direction is oriented parallel to the surface 4 of the floor finishing material 1, heat can be efficiently transferred to the surface 4 side. Furthermore, since the floor surface can be directly shaped using the floor finishing material 1 without using heating panels as in the past, the number of construction steps is reduced.
Both are extremely advantageous. Since the reflective material 8 is provided on the back surface 5 of the floor finishing material I, it is possible to reduce the heat escaping from the back surface 5 side by radiation, and since the heat insulating material 9 is provided, the heat escaping from the back surface 5 side can be reduced. Heat escaping through thermal conduction can also be reduced.

In addition, since the heat transfer tubes 7 are fixed to the grooves 6 of the floor finishing material 1 with an elastic adhesive, even if the heat transfer tubes 7 and the floor finishing material 1 expand or contract due to thermal expansion, etc., the difference in the amount of expansion or contraction can be compensated for by elasticity. It can be absorbed by adhesives, and unnecessary stress will not be generated on heat exchanger tubes or floor finishing materials. That is, due to the difference in the amount of expansion and contraction between the heat exchanger tubes 7 and the floor finishing material 1, the heat exchanger tubes 7 may be bent or
It is possible to prevent problems such as warping of the floor finishing material I.

Furthermore, since the elastic adhesive contains metal powder with good thermal conductivity, heat can be efficiently transferred from the heat transfer tube 7 to the floor finishing material 1.

Furthermore, the pitch P of the heat transfer tubes 7 is P=K×D2/t1 11.0≦K≦30,0 However, K is a constant, and the inner diameter t of the heat transfer tubes before being flattened is the floor finishing material. Since the thickness is set as such, a constant amount of heat can be supplied to the surface 4 of the floor finishing material I, and the entire surface 4 can be evenly heated to a substantially uniform temperature. .

In the above embodiment, the heat exchanger tube 7 has a flat cross section, but it goes without saying that the heat exchanger tube 7 may have a circular cross section.

Further, the heat exchanger tube 7 may be made of other materials such as aluminum in addition to copper.

[Effects of the Invention] As explained above, according to the heating floor finishing material of the present invention, the floor finishing material has a groove formed on the back surface, and the floor finishing material is fitted into the groove of this floor finishing material and elastically adhered to the branch groove. It is equipped with a heat transfer tube fixed with an agent, a reflective material provided to cover the back surface of the floor finishing material including the heat transfer tube, and a heat insulating material laminated on this reflective material. A floor surface for heating can be formed by directly laying floor covering material on top. Therefore, heat can be transferred directly from the heat exchanger tubes to the floor covering, so even if the floor covering warps,
The floor finishing material can be heated at a constant temperature without hindrance to heat transfer from the heat transfer tube to the floor finishing material. And just like before? Since heating panels are not used, the number of construction steps can be reduced. Since a reflective material is provided on the back side of the floor finishing material, it is possible to reduce the heat escaping from the back side by radiation, and since a heat insulating material is provided, the heat escaping from the back side by heat conduction can also be reduced. can be reduced.

In addition, since the heat transfer tubes are fixed in the grooves of the floor finishing material with an elastic adhesive, even if the heat transfer tubes and the floor finishing material expand or contract due to thermal expansion, the difference in the amount of expansion or contraction is absorbed by the elastic adhesive. This makes it possible to avoid unnecessary stress on heat exchanger tubes and floor finishing materials. Therefore, due to the difference in the amount of expansion and contraction between the heat exchanger tube and the floor finishing material, the heat exchanger tube may bend or
It is possible to prevent problems such as warping of floor finishing materials.

On the other hand, if the pitch P of the heat transfer tubes is set to P = K It has the advantage of being able to supply an amount of heat to the surface of the floor finishing material, and also being able to heat the entire surface evenly.
