Abstract

PURPOSE:To prevent a settlement of a floor plate or a pipe deformation and facilitate handling of the mat when a flow communication is performed by a method wherein a foam resin sheet having a resin pipe for a thermal medium flow passage buried therein is provided with several hard fine elongated plates, their longitudinal directions are crossed at a right angle perpendicular to a bending direction of the sheet and they are adhered to each other with a certain spacing being left therebetween. CONSTITUTION:A floor heating mat 1 has a foam polyethylene sheet 2 and a resin pipe 3 buried in the sheet 2. The resin pipe through which thermal medium such as hot water is passes is disposed to cover an entire sheet. Hard several fine and elongated plates 4 harder than the foam resin sheet 2 are adhered to a rear side of the foam resin sheet 2. Adhering of the fine and elongated plates 4 is carried out in such a way as their longitudinal directions are crossed at a right angle perpendicular to a bending direction of the foam resin sheet and they are spaced apart from each other, resulting in that the mat 1 can be bent and rounded. With such an arrangement, the floor settlement or a pipe deformation is hardly generated and its handling (transportation or storing or the like) may easily be carried out.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a floor heating mat used when performing floor heating.

[Conventional technology and problems]

Conventionally, when performing floor heating, as shown in Fig. 7, the floorboard 6
Under the floor heating system 4, a maturo 1 for floor heating is arranged. In this Matsutoro 1 for floor heating, there is a resin vibro 3 for the heat medium flow path.
is embedded in a resin foam sheet 62, and heat is supplied from below the floorboard 64 by passing a heat medium such as hot water through the resin vibro 3.

However, in the case of the above floor heating, there are the following problems.

One problem is that depending on the amount of load applied to the floor plate 64, the floor plate 64 may sink, as shown in FIG.

The other problem is that as the floorboard 64 sinks, the heating maturo 1 is compressed, and as shown in FIG. It's a matter of what happens.

Not only that, but the above-mentioned mats used for floor heating are quite large. During distribution, it cannot be said to be practical unless it is easy to transport, store, and handle. [Problem to be solved by the invention] In view of the above circumstances, this invention is designed to prevent subsidence of floorboards and deformation of pipes. Moreover, it is an object of the present invention to provide a floor heating mat that is easy to handle during distribution and is highly practical.

[Means to solve the problem]

In order to solve the above problems, the inventors made extensive studies from various angles. We also focused on the fact that there is a foamed resin layer of appropriate thickness on the underside of the resin pipe, which prevents heat from escaping to the back side. If this part is made harder, the floor will be less likely to sink. However, the hard layer makes handling difficult. Underfloor heating mats can no longer be folded and rolled up, making them difficult to transport and store. Therefore, the inventors continued their studies and decided to attach a large number of elongated plates, which are harder than the sheet, to the foamed resin sheet embedded in the resin pipe, with the longitudinal direction perpendicular to the bending direction of the foamed resin sheet. The inventors discovered that it was possible to easily roll up a Ma-7 by attaching them to each other with a space between them, and thus completed this invention.

Therefore, the floor heating mat according to claim 1.2 is as follows:
A foamed resin sheet in which a resin pipe for a heat medium flow path is embedded is provided with a large number of elongated plates that are harder than the same sheet, with their longitudinal directions perpendicular to the bending direction of the foamed resin sheet, and are aligned with each other. The structure is such that they are pasted together with a gap between them.

In addition, the floor heating mat according to the second aspect of the present invention has a structure in which a hard member for preventing sinking is also embedded in the foamed resin sheet at an appropriate position where there is no pipe.

The foamed resin sheet of this invention usually has an expansion ratio of 10.
-40 or so, and specifically, for example, a foamed polyethylene sheet is exemplified.

The elongated plate material of the present invention is also preferably made of foamed resin, and usually has an expansion ratio of less than 10, such as an extruded foamed polystyrene plate material.

There are various ways to embed resin pipes in foamed resin sheets.

One type is a resin pipe completely buried in a foamed resin sheet. For example, this form can be adopted by molding a foamed resin sheet together with the resin pipe. Then, an elongated plate material is pasted on the back side of the same sheet. Note that a thin sheet may be attached to the surface.

The other type is a resin pipe fitted into a groove formed in a foamed resin sheet.

Grooves for piping are: ■ When formed on the sheet surface (floorboard side surface) (with a non-penetrating groove, the opening surface will be on the surface), ■ When formed on the back side of the sheet (with a non-penetrating groove, the opening surface will be the surface) (becomes the back side); (2) There are cases where the sheet is punched out on both the front and back sides (the opening surface is on both the front and back sides due to the through groove).

Paste another sheet, etc. on the fully open side to keep the groove cold. In the case of (2) above, a thin sheet is attached to the surface. Then, an elongated plate material is attached to the back side of the foamed resin sheet. In the case of (2) above, an elongated plate material is pasted on the back side of the foamed resin sheet. In the case of (2) above, a thin sheet is attached to the front surface of the foamed resin sheet, and an elongated plate material is attached to the back surface. Thin sheets include resin films, foamed resin thin sheets, nonwoven fabrics, woven fabrics, and the like. The elongated plate material bonded to the back of the foam resin sheet also works to prevent heat from the resin pipes from escaping in the opposite direction to the floor.

Further, in the floor heating mat of the present invention, a hard member for preventing sinking may be further embedded in the foamed resin sheet with the resin pipe for the heat medium flow path at an appropriate position where the pipe is not provided.

Examples of hard members include those that have a cylindrical or prismatic shape and are made of low expansion ratio resin materials (low expansion ratio polystyrene, low expansion ratio polypropylene, etc.), foamed rubber materials, unfoamed resin materials, wood, etc. Ru.

These hard members are provided in a state in which they are aligned vertically and horizontally with a pinch of about 150 to 300 W. Floor heating mats are
Usually, it is fixed by nailing every 150 to 300,
If you drive a nail into a hard member, you can easily determine the nailing position using the hard member as a landmark, and the fixation state will also be a value. In this case, it can be said that the mat has excellent workability because it is easy to apply and can be applied reliably.

When burying the above-mentioned hard member for preventing sinking, normally, punch holes are first formed in the foamed resin sheet, and the hard member is inserted into the holes.

The resin pipe and the hard member may both be buried at the same time, the resin pipe may be buried first and the hard member later, or the hard member may be buried first and the resin pipe buried first and the hard member buried later. The pipe may be buried later.

The present invention is not limited to the configuration illustrated above. For example, the resin of the foamed resin sheet is not limited to polyethylene, but may be other types of resin such as polystyrene or urethane resin. In addition, although a large number of long and thin plates are usually separated one by one, this is not the only option. For example, as shown in FIG. It is also possible to use a plate material that is covered with a wall with a wide space between them.
'b is attached to the back side of the foamed resin sheet.

[For production]

In the floor heating mat according to the present invention, a large number of elongated plates that are harder than the foamed resin sheet embedded in the resin pipe for the heat medium flow path are laminated to each other, and therefore the floor heating mat is less prone to floor subsidence than before. In addition to making it difficult for pipe deformation to occur, the long and thin plates are pasted together so that the longitudinal direction of the plates is perpendicular to the bending direction of the foamed resin sheet, and there is a gap between them. Since it can be folded and rolled, handling (transportation, storage, etc.) is extremely easy.

In addition, with foamed resin sheets embedded in resin pipes,
A hard member is embedded in an appropriate position where there is no pipe, and the hard member portion is not crushed and is firmly maintained at the sheet thickness interval, so in this case, floor subsidence and pipe deformation are less likely to occur.
