BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor heating panel used for constructing a floor heating type floor of a house or the like, and in particular, a heat transfer plate is attached to an upper surface of the panel and the heat transfer surface thereof. And a floor heating panel directly laid on the surface of a concrete floor slab.

[0002]

2. Description of the Related Art Conventionally, when a floor heating panel is installed on a concrete floor slab, a joist is fixed on the floor slab, a heat insulating material is packed between the joists, and the floor heating is applied on the joist. In general, a method of laying a panel for installation or putting a discard plate on the joist and laying a floor heating panel on it is adopted, but in this method, the joist is used,
There is a drawback that the construction cost is high due to the material cost of the joists and the labor for installation.

In place of this joist method, a method of laying floor heating panels directly on the surface of a concrete floor slab has been adopted. However, the concrete floor slab surface
In most cases, it is not finished to a smooth surface, and when using a hard foam resin as a floor base material, a method of partially filling mortar has been taken to absorb unevenness of the floor slab surface, Until the mortar was solidified, it was not possible to proceed to the next operation, and even after the mortar was solidified, the mortar and the foamed resin were not bonded, which caused so-called floor noise.

In order to solve the above-mentioned problem of floor noise, the present applicant has previously proposed a floor heating panel as shown in FIG. In this panel for floor heating, a heat transfer plate 6 is attached to an upper surface of a panel body 5 made of a hard foamed resin, and a piping groove for accommodating a flexible tube 4 for flowing a heat medium on the upper surface of the heat transfer plate 6. 7 is formed, and a lower sheet 8 made of a soft foamed resin is laminated on the lower surface of the panel body 5. According to this floor heating panel, the lower sheet absorbs irregularities on the surface of the concrete floor slab. In addition to being able to adhere to the floor slab with the adhesive, it is possible to prevent the floor from squeaking, and the soundproofing effect of the lower sheet can further enhance the soundproofing effect of the entire panel.

However, in the above floor heating panel, when the floor heating is used, warpage deformation occurs such that the upper surface of the panel has a convex shape due to thermal expansion of the heat transfer plate as shown by the phantom line in FIG. There is a problem that irregularities are formed on the surface of the floor to be heated.

[0006] The present invention can prevent the above-described warping deformation of the entire panel, and imparts soundproofing and heat-insulating properties to the panel itself to reduce the impact noise generated on the indoor floor of the upper floor. It is an object of the present invention to provide a floor heating panel capable of minimizing propagation to a lower floor.

Are laminated, and a rigid reinforcing plate 2 on the upper surface of the panel body is provided.
1, a heat transfer plate 6 is attached to the heat transfer plate 6, and a pipe groove 7 for accommodating a flexible tube 4 for flowing a heat medium is recessed on the upper surface side of the heat transfer plate 6, and a rigid reinforcing plate 22 on the lower surface of the panel body is formed. Is equipped with a lower sheet 8 having soundproofing and flexibility and capable of bonding to the surface of the concrete floor slab S.

The panel body 15 made of the paper honeycomb is excellent in heat insulation and sound insulation, has sufficient compressibility, and is lightweight.
Good workability.

As described above, the floor heating combination panel which is directly laid and adhered to the upper surface of the concrete floor slab S is a panel body of each of the panels 2 and 3 (the straight piping panel 2 and the folded piping panel 3). Rigid reinforcing plates 21 and 22 are laminated on the upper and lower surfaces of 5, 5 and 15, respectively, and the heat transfer plate 6 is attached to the rigid reinforcing plates 21 on the upper surfaces of the panel bodies 5 and 15,
The lower sheet is attached to the rigid reinforcing plate 22 on the lower surface side of the panel bodies 5 and 15, and the rigid reinforcing plates 21 and 22 laminated on both upper and lower surfaces of the panel bodies 5 and 15 have been used as a conventional transmission. The warpage of the panel as shown in FIG. 7 due to the thermal expansion of the hot plate 6 is eliminated, so that there is no inconvenience that uneven portions are formed on the surface of the floor to be heated.

That is, since the rigid reinforcing plates 21 and 22 are laminated on the upper and lower surfaces of the panel bodies 5 and 15, respectively, even if the heat transfer plate 6 attempts to thermally expand during floor heating, the thermal expansion is increased by the upper surface rigidity. It is obstructed by the reinforcing plate 21 and thus the warpage of the panel bodies 5, 15 is avoided. Further, the pipe grooves 7 of the heat transfer plate 6 interposed inside the panel bodies 5 and 15 are formed.
Even if the lower surfaces of the panel bodies 5 and 15 are compressed due to a tensile action on the upper surfaces of the panel bodies 5 and 15 due to the thermal expansion of the portions, the lower surfaces of the panel bodies 5 and 15 are compressed by the lower surface rigid reinforcing plate. As a result, the warpage of the panel bodies 5, 15 is avoided.

Further, since the panel bodies 5 and 15 are formed of a material having heat insulating property, soundproofing property and sufficient compressive strength, the panels are compressed and deformed by the load of furniture or pedestrians placed on the indoor floor. It can be used in a stable state for a long time without sinking, and almost no impact sound generated when an object falls on the floor of the upper floor is transmitted to the lower concrete floor slab S. . Further, the heat of the heat transfer plate 6 warmed by the heat medium flowing through the heat medium flowing flexible tube 4 can be effectively used by the heat insulating effect of the panel body 5.

Further, a lower sheet 8 having soundproofness and flexibility capable of absorbing irregularities on the surface of the concrete floor slab S is mounted on the back surfaces of the panel bodies 5 and 15, so that the lower sheet 8 is made of concrete. The unevenness on the surface of the floor slab S can be absorbed and brought into close contact with the floor slab S, and the floor slab S can be bonded to the floor slab S with an adhesive. Further, since the lower sheet 8 is formed of a soft foamed resin such as urethane foam, the soundproofing property and the heat insulating property of the panel can be further enhanced.

Further, the panel bodies 5 and 15 themselves have soundproofing properties, and the rigid reinforcing plates 22 on the lower surfaces of the panel bodies 5 and 15 are provided.
Since the lower sheet 8 mounted on the floor has sound insulation and flexibility, it is not necessary to provide a sound insulation material on the back surface of the surface finishing material attached to the surface of the floor heating panel. The heat of the heat transfer plate 6 warmed by the heat medium flowing inside can be quickly transmitted to the flooring board 14 as a surface finishing material.

The lower sheet is attached to the rigid reinforcing plate on the lower side of the panel body, and the rigid reinforcing plates laminated on the upper and lower surfaces of the panel body solve the problem of panel warpage due to thermal expansion of the heat transfer plate, The inconvenience of forming irregularities on the surface of the floor to be heated is eliminated.

Further, since the panel body is made of a material having heat insulating property, soundproofing property and sufficient compressive strength, the panel may be deformed and settled by compressive deformation due to the load of furniture or the like placed on the floor. It can be used in a stable state for a long period of time, and it is difficult for the impact noise generated by falling objects etc. on the upper floor to be transmitted to the lower concrete floor slab and does not affect the lower floor, and the heat insulation of the panel body By the effect, the heat of the heat transfer plate heated by the heat medium such as hot water flowing in the flexible tube for flowing the heat medium can be effectively used.

The rigid reinforcing plate on the lower surface of the panel body includes
Since the lower sheet which is soundproof and has the flexibility to absorb irregularities on the surface of the concrete floor slab and can be bonded to the surface of the concrete floor slab is mounted, the lower sheet absorbs the irregularities on the surface of the concrete floor slab. In addition to being able to adhere to the floor slab by the adhesive, the floor can be prevented from generating noise, and the soundproofing effect of the lower sheet can further enhance the soundproofing effect of the entire panel.

Further, since the panel body itself has soundproofing properties and the lower sheet attached to the rigid reinforcing plate on the lower surface of the panel body has soundproofing properties and flexibility, the back surface of the surface finishing material attached to the surface of the floor heating panel is provided. Does not need to be provided with a sound insulating material, so that the heat of the heat transfer plate warmed by the heat medium flowing through the flexible tube for flowing the heat medium can be quickly transmitted to the surface finishing material.

As described in the second aspect, when each rigid reinforcing plate is formed of a wood-based material, each rigid reinforcing plate has sufficient rigidity and heat insulation, so that warpage of the panel can be more effectively prevented. In addition, the weight of the panel can be reduced.
