Abstract

PURPOSE:To get a heating thermal insulation material base capable of performing an efficient supply of heat to an upper surface of a floor by a method wherein an aluminum foil layer is placed on the surface of non-organic fibrous thermal insulation material and a heating means forming a predetermined arrangement is placed. CONSTITUTION:A heating thermal insulating material base is made such that a surface of a rock wool molded product (a thermal insulation material) 1 is machined to form piping grooves 2, an aluminum foil 3 molded in compliance with a shape of the piping grooves 2 is bonded to a surface of each of the piping grooves 2 to form aluminum foil bonded grooves 4. Heating pipes 5 are fed into the aluminum foil bonded grooves 4 and mounted in them. The aluminum foil 3 placed and disposed between the thermal insulation material 1 and the heating pipes 5 prevents the pipe from being settled or buried into the thermal insulation layer by its own weight after its use of long period of time. A loss of thermal energy is reduced by a thermal conductivity as well as a heat energy reflecting performance found in the aluminum foil and then the heat can be efficiently supplied onto the surface of the floor.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a heating insulation material base used for floor heating of buildings and a method for manufacturing the same.

[Conventional technology]

Conventionally, heating means are installed on the top surface of a layer of insulation material laid on the top surface of a floor such as a concrete slab or floorboard, or grooves are formed in a predetermined arrangement on the top surface of the layer of insulation material. A floor heating system is known in which a heating means consisting of an electric resistance wire (heater) or a hot water vibrator is installed in a submerged state in a groove, and a heating layer, a heat storage material, and a floor finishing material are further laid on top of the heating means (specially (Refer to Japanese Patent No. 186134/1983).

[Invention or problem to be solved]

However, in these conventionally known floor heating devices, the heating means is installed on the upper surface of the heat insulating material layer or in the groove formed on this upper surface, and this heating means deteriorates due to long-term use. Due to its own weight, it sinks into the insulation layer, sometimes completely burying it, and as a result, the heat radiation and heat transfer effect from the heating means is blocked, and the heat is not sufficiently transferred to the upper part of the floor. Since the heating temperature is around 85°C, if the heat radiation loss is large, the heating effect will decrease.
There was a problem.

(Means for Solving the Problems) In order to solve the above-mentioned problems, as a result of various researches, the present inventors installed an aluminum foil between the heat-insulating material and the heating means to create a heat-insulating material base. By doing so, it is possible to prevent the heating means from sinking or being buried in the heat insulating material layer.
Furthermore, it has been discovered that the thermal energy reflection performance and high thermal conductivity of aluminum foil can reduce the loss of thermal energy and efficiently supply heat to the upper part of the floor, and the above-mentioned heating insulation material base can be manufactured advantageously. They also discovered a method and completed the present invention.

That is, the present invention is a heat insulating material base for heating, characterized in that heating means are provided in a predetermined arrangement with an aluminum foil layer interposed on the surface of an inorganic fiber-based heat insulating material.

The heating means may be placed in grooves formed in a predetermined arrangement on the surface of the heat insulating material, with an aluminum foil layer interposed therebetween, in a predetermined arrangement.

Furthermore, the present invention involves interposing an aluminum foil layer on the surface of the S-quality raw wool mat, and forming grooves with the aluminum foil layer interposed therebetween by hot press molding using a mold with protrusions forming a predetermined arrangement. , a method of manufacturing a heat insulating material base for heating, characterized in that a heating means is inserted and installed in the groove.

Furthermore, the present invention interposes an aluminum foil layer on the surface of the inorganic fiber layered raw wool mat, arranges heating means in a predetermined arrangement, and hot-press molds it in a mold to form grooves in a predetermined arrangement. This is a method of manufacturing a heat insulating material base for heating, which is characterized in that a heating means and an aluminum foil layer are immersed and installed at the same time.

In the present invention, as the inorganic fiber-based heat insulating material, non-combustible fibers such as glass wool, rock wool, slag wool, etc. are molded into a predetermined shape using a binder. At this time, in order to improve the intertwining of the fibers and improve the compressive strength of the inorganic fiber layer, for example, the fiber raw material is knitted into thin layers in the form of a mat or sheet, and then multiple layers of these are stacked in the same direction or in different directions. It is preferable to use one that is compressed horizontally rather than vertically. The inorganic fiber layer obtained in this way is mainly horizontal to the sheet surface, but the fiber components are also bent and folded in the vertical direction, and the fibers are intertwined three-dimensionally, so the compressive strength is low. It is excellent.

Further, the thickness of the aluminum foil is preferably in the range of 30 to 50 gm when the heating means is a wiring method, and is preferably in the range of 100 to 200 μm when the heating means is a piping method.

The present invention will be explained in detail below.

In the heating insulation material base of the present invention, the heating means installed above the insulation material or immersed in a groove formed on the surface of the insulation material is a heating means that is normally used with gas. There are two methods: a piping method that passes hot water, and a wiring method that heats with an electric heater.

Therefore, the grooves formed on the surface of the heat insulating material are piping grooves or wiring grooves.

Note that when using the electric heater, since aluminum foil is also used at the same time, an insulated one is naturally used.

The heating insulation material base of the present invention may be formed by interposing aluminum foil between the insulation material and the heating means, or the aluminum foil may be installed on the entire upper surface of the insulation material, or the aluminum foil may be installed on the entire upper surface of the insulation material. It may be installed only at a position directly below where the heating means is installed on the upper surface of the heat insulating material, or only near the groove formed on the surface of the heat insulating material. Further, when the heating means is installed so as to be immersed in a groove formed on the surface of the heat insulating material, it is preferable that the heating means is not completely buried in the groove but is installed in a partially exposed state.

If it is completely buried, the heat radiation and heat transfer effect from the heating means will be blocked by the heat insulating effect of the surrounding heat insulating material, and heat will not be sufficiently transferred to the upper part of the floor.

As a method for manufacturing the heating insulation substrate of the present invention, for example, the following method may be used in the case of a seven-skin wool molded product, and the same method can be carried out when glass wool, ceramic fiber molded products, etc. are used.

(a) A groove is formed by machining the surface of a rock wool molded product, and an aluminum foil, which is separately molded to fit the shape of the groove, is adhered to the surface of the groove to form a groove with aluminum foil. ,
Next, the heating means is inserted and installed in the aluminum foil groove.

In this method (a), piping is mainly laid within the aluminum foil groove. At this time, in view of the pipe diameter, the thickness of the heat insulating material is usually preferably 25 mm or more.

(b) Hot press mold the surface of the rock wool residual wool with a grooved mold to form grooves, and then separately mold aluminum foil to fit the shape of the groove and adhere it to the surface of the groove. A groove with aluminum foil is formed, and then a heating means is inserted and installed in the groove with aluminum foil.

Note that by hot press molding, the thermosetting binder in the raw wool mat is thermally cured to form a cured molded body to which the inorganic fibers are partially adhered.

(C) Place aluminum foil on the surface of rock wool leftover wool, simultaneously hot press mold with a grooved mold to form an aluminum foil groove, and then install a heating means by immersing it in the aluminum foil groove. .

In the method (b) or (C) above, piping or wiring is laid within the aluminum foil groove. When wiring is laid, a wiring pattern grooved mold is used as the grooved mold. In this case, the machining pattern of the wiring groove is relatively complicated, but
The thickness of the heat insulating material may be thin and is usually preferably 10 to 20 mm.

In the methods (a) to (C) above, only grooves are formed on the surface of the heat insulating material, and even if no heating means are installed, it can be processed at the factory, and piping or wiring can be done at the construction site. In this case, it saves labor during on-site construction, and is also excellent in on-site construction.

(d) Rock wool An aluminum foil is placed on the surface of the leftover wool, an electric heater is placed on the aluminum foil, and this is simultaneously hot press molded.

This method (d) is applied when an electric heater is embedded in the insulation material at the same time as hot pressing.In this method, hot press molding is performed including the electric heater, excluding the terminal part, and then the terminal part is attached. It is also possible to make it into a panel.

When the heating insulation material base of the present invention is actually used for floor heating, various forms can be considered. For example, it is used by laying it on the top surface of a floor such as a concrete slab or floorboard.

Furthermore, on top of the heating insulation material base of the present invention, a conventionally known heating layer [formed by a mortar layer, a gypsum board layer], or a space (an air layer) partitioned by aggregates or spacers such as plastic or wood, etc. ), heat storage materials (based on nitrate, calcium chloride, and sodium acetate), floor finishing materials, etc. will be installed.

For example, the heating insulation material base of the present invention (heating pipes are installed in grooves with aluminum foil formed on the surface of the floor heating insulation material) is installed on the floorboard, and a plywood board is placed on top of this as a temporary covering. Alternatively, a floor heating device can be obtained by laying felt and further laying a surface finishing material on top of the felt.

In addition, grooves with aluminum foil are processed on the surface of the tatami floor (insulating material) of tatami mats made of rock wool, etc., the heat source is immersed in these grooves, and a tatami cover is laid on top of this to heat the tatami. A device is obtained.

Furthermore, the tatami heating system can be created by installing an electric heater with aluminum foil on top of the tatami floor (insulation material) and laying a tatami cover on top of it, without installing the heat source immersed in the insulation material. It is also possible to do this. Currently, carpet (filling = 0.04 to 0.044 Kca) is used as a heating base material.
l/m, h, 'C), wood (in = 0.07~0.1
5Kcal/ m, h, 'C), concrete (in =
1.2Kcal/m, h, 'C) etc., but compared to these base materials, for example, rock wool (λ=0.035~
0.037 Kcal/m, h, 'C) has low thermal conductivity and high heat insulation efficiency. Therefore, the heating insulation material base of the present invention has excellent heat insulation performance.
