Description

  The present invention relates to a latent heat storage floor structure in which a heat storage unit can be combined with a heat generation panel as necessary.

  Conventionally, as a floor heating panel for heating a floor surface inside a building, for example, as shown in Patent Document 1, a plate-shaped heat insulation in which a groove is formed on an upper surface and a linear heater is accommodated in the groove. There is known a heat generating mat that is integrally joined to a side edge of the heat insulating material and a small joist having the same thickness as the heat insulating material.

JP-A-7-293911

  However, in the thing of the said patent document 1, since the heater accommodated in a ditch | groove is disperse | distributed and arrange | positioned in the upper surface of a heat insulating material, the heat_generation | fever of the heater is a floor finishing material (floor surface) above a heat-generating mat. As a result, there is a temperature difference between the part with and without the heater. Therefore, although the thing of the cited reference 1 has arrange | positioned the soaking | uniform-heating board which consists of a metal plate on a heat insulating material and small joists, the soaking effect is inadequate and it is inevitable that temperature nonuniformity arises. .

  Therefore, instead of using a metal heat equalizing plate, a heat storage unit containing a latent heat storage material is placed on the heat generating mat to enhance the heat equalization effect on the floor surface, and even after turning off the heater, It is conceivable to obtain the merit that warmth can be maintained for a certain time by the stored heat.

  However, in that case, on the other hand, when the floor surface is warmed from the cold state, the heat from the heater is once stored in the heat storage material, so that the temperature rise of the surface is deteriorated. Thus, if a heat storage material is incorporated in the unit as a heat generating panel, advantages and disadvantages will occur. The simplest way to solve this problem is to design a dedicated product and line up products with and without heat storage material on the heating panel so that they can be selected according to the purchaser's preference. This is not preferable because a dedicated product is set, the number of product numbers increases, and the stock burden increases.

  In addition, as a heat storage material, a fiber board or resin is used in which a latent heat storage agent having PCM characteristics such as paraffin or metal hydrate salt is encapsulated in a resin container, or a heat storage material having PCM characteristics is microencapsulated. It is common to use what was kneaded into a plate and formed into a plate shape. In this case, there has been no method for stably arranging such a plate-shaped product with good workability between the base panel having the heat generating portion and the floor finish.

  The present invention has been made in view of such various points, and the object thereof is to improve the heat storage unit having small joists sold by various manufacturers and the floor structure on which the heat storage unit is constructed, thereby providing a heat storage unit. In this case, the heat storage unit can be disposed on the heat generating panel as necessary, and the construction reliability of the heat storage unit is improved.

  In order to achieve the above object, the present invention uses small joists in a heat generating mat with small joists, and further arranges joists on them and arranges heat storage units of the same thickness adjacent to the joists. In addition, floor finishing materials are installed on the heat storage unit and the joists, and for this reason, the heat storage unit can be arranged on the heat generating panels sold by various manufacturers as needed.

  Specifically, the latent heat storage floor structure according to the first invention includes a plurality of heat generating mats in which a plate-like base portion having a heat insulating material in which a heat generating portion is accommodated and at least one small joist are joined and integrated. Is installed on the floor base, and at least a part of the heat storage unit having the latent heat storage material is placed on the base of the heat generating mat, and the same thickness as the heat storage unit is placed on the small joists of the heat generating mat. At least a part of the upper joist is superposed, and the floor finish is fixed on the upper joist on the heat storage unit and upper joist.

  In the present invention, heat generation includes not only warm heat but also cold heat.

  In the first aspect of the invention, since the heat storage unit is disposed on the base of the heat generating mat so as to overlap the floor finishing material above the base of the heat generating mat, the heat conducted from the heat generating mat to the floor finishing material is temporarily Heat stored in the heat storage unit and released from the heat storage unit is conducted to the floor finish. The heat storage effect of such a heat storage unit can enhance the soaking effect on the floor finishing material, that is, the floor surface.

  In addition, at the time of construction, at least a part of the upper joist having the same thickness as the heat storage unit is stacked on the small joist of the heat generating mat, and the upper joist is fixed to the floor base together with the small joist of the heat generating mat. Place the heat storage unit next to the upper joist so as to overlap the base of the heat generating mat, place the floor finishing material on this upper joist and the heat storage unit and fix it on the upper joist, Thus, the reliability of the construction of the heat storage unit can be improved.

  Further, the upper joists placed on the small joists of the heat generating mat are visible, and when the upper joists are fixed and the floor finish is fixed to the upper joists using flooring staples or screws, they can be visually observed. Since it is applied to the upper joist, the construction staples and screws will not accidentally damage the heat storage unit and the heat generating portion of the heat generating mat, and the reliability of the work can be improved.

  According to a second aspect of the present invention, in the first aspect, the upper joist is arranged in parallel with the small joists of the heat generating mat and is entirely overlaid on the small joists, and the heat storage unit is entirely on the base of the heat generating mat. It is characterized by being superimposed on.

  In the second aspect of the invention, the upper joists are arranged in parallel to the small joists of the heat generating mat, the whole is superposed on the small joists, and the entire heat storage unit is superposed on the base of the heat generating mat. The same effect as that of the present invention can be obtained. In particular, since the entire upper joist is superposed on the small joist of the heating mat, the position of the upper joist accurately corresponds to the position of the small joist and the construction reliability can be further enhanced.

  According to a third aspect of the present invention, in the first aspect, the upper joists are arranged so as to be orthogonal to the small joists of the heat generating mat, and a part of the upper joists are stacked on the small joists. It is overlaid on the base and the rest of the small joists, and the upper joists are arranged immediately above the heat generating portions of the heat generating mat.

  In the third aspect of the invention, the upper joists are arranged orthogonally to the small joists of the heat generating mat, a part thereof is overlaid on the small joists, and the heat storage unit is overlaid on the base of the heat generating mat and the remaining portion of the small joists. Since the upper joists are arranged immediately above the heat generating portion of the heat generating mat, the same effect as the first invention can be obtained. In particular, since the heat storage unit is arranged not only on the base of the heat generating mat but also on the small joist, the floor finishing material also has a portion of the heat storage unit corresponding to the small joist on the base of the heat generating mat without the heat generating portion of the base. A significant effect can be expected that heat can be conducted and the soaking effect of the floor finish can be further enhanced.

  According to a fourth invention, in any one of the first to third inventions, the heat generating portion of the heat generating mat is a hot water pipe through which hot water flows.

  Further, a fifth invention is characterized in that, in any one of the first to third inventions, the heat generating portion of the heat generating mat is a hot water pipe through which hot water heated using solar heat flows. To do.

  In this 4th and 5th invention, when the heat generating part of the heat generating mat is a hot water pipe, it is possible to enhance the soaking effect on the floor finish and the workability of the heat storage unit.

  According to a sixth invention, in any one of the first to fifth inventions, in the upper joist, at least one of a notch concave portion or a notch step portion is formed in a part of the upper joist that overlaps the vertical joist. It is characterized by.

  In the sixth aspect of the present invention, a notch recess or a notch step is formed in a part of the upper joist that overlaps the small joist of the heat generating mat. When fixing to the base material with a fastener, insert the fastener into the bottom of the notch recess or the bottom of the notch step, and drive the fastener into the floor substrate through the small joist of the heat generating mat. Not only can the length of the fastener be shortened by the depth of the notch recess or notch step, but also a remarkable effect can be expected that the strength can be stabilized.

  As described above, according to the present invention, it is possible to arrange a heat storage material with good workability as necessary on a heat generating panel supplied from various manufacturers. In addition, at least a part of the heat storage unit having the latent heat storage material is placed on the base of the heat generating mat installed on the floor base, and at least one of the upper joists having the same thickness as the heat storage unit is placed on the small joist. By stacking the parts and constructing the floor finishing material on top of these heat storage units and upper joist, the heat storage effect of the heat storage unit can enhance the soaking effect on the floor finishing material, The workability of the unit can be improved.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The following description of the embodiments is merely illustrative in nature and is not intended to limit the present invention, its application, or its use at all.

(Embodiment 1)
1 and 2 show a latent heat storage floor structure according to Embodiment 1 of the present invention. Reference numeral 1 denotes a floor base on a floor surface inside a building, and a plurality of sheets for floor heating are provided on the floor base 1. Koneta hot water mats 3, 3, ... (exothermic mats) are spread and installed.

  Each small joist hot water mat 3 has a rectangular plate-like base 4 made of a heat insulating material, and a plurality of concave grooves 5, 5,... Are formed on the upper surface of the base 4, and heat is generated in each concave groove 5. The hot water pipe 6 as a part is accommodated. The hot water pipe 6 is connected to, for example, a hot water heater device (not shown) for heating using solar heat, and hot water heated using solar heat in the hot water heater device flows through the hot water pipe 6. Heat of the hot water is transmitted to the surface (floor surface) of the floor finishing material described later for heating. In addition, the hot water pipe 6 is connected to a hot water heater device (for example, a gas water heater or an electric water heater) that heats water with a heat source other than sunlight, and the hot water from the hot water heater device is caused to flow into the hot water pipe 6. You may do it.

  Further, the small radish warm water mat 3 has two small radish 8 and 8 which are joined and integrated at both ends of the base portion 4 in the width direction and extend in parallel with each other. The radish warm water mat 3 is fixed to the floor foundation 1 by inserting a fastener (not shown) such as a nail or the like and stopping it on the floor foundation 1. In addition, the number of the small joist 8 in the small joist hot water mat 3 may be one other than two, or three or more.

  The entire heat storage unit 11 having a latent heat storage material is stacked and placed on the base 4 of the small joist hot water mat 3.

  The heat storage unit 11 is in the shape of a rectangular thin plate box, and as shown in FIG. 4, a frame portion 12 assembled in a rectangular frame shape by a frame material (wooden frame) such as wooden, and bonded to both surfaces of the frame portion 12. A pair of integrated panel members 13 and 13 is provided, and a space surrounded by the frame portion 12 and both panel members 13 and 13 is filled with a heat storage body 14 and incorporated. When assembling this heat storage unit 11, for example, after assembling the frame portion 12 with a frame material in advance and applying an adhesive on both sides of the frame portion 12, both panel materials 13, 13 is put together according to the frame part 12, and it is assembled by cold-pressing and bonding them together.

  The heat storage body 14 has a bag-shaped pack made of flexible aluminum or the like having a rectangular size slightly smaller than the space in the frame portion 12 and a thin thickness (for example, 15 mm). A latent heat storage material (not shown) is hermetically filled and sealed inside.

  Since the latent heat storage material is enclosed in a pack, a latent heat storage material that is not microencapsulated, a gelatinized latent heat storage material, or the like can also be used. For example, n-octadecane or n-hexadecane is used as the latent heat storage material. This normal paraffin has a melting point of 18 to 32 ° C., basically becomes a solid at a temperature lower than the melting point, and becomes a liquid at a temperature higher than the melting point. The melting point temperature of the latent heat storage material 13 is preferably set to, for example, around 20 ° C., which is close to the heating set temperature for heating in winter. The normal paraffin as the latent heat storage material is used as it is packed in the sealed portion as it is, and changes in phase with solid / liquid according to the temperature change. The specific gravity of normal paraffin is about 0.8.

  As latent heat storage materials other than normal paraffin, inorganic hydrate salts (calcium chloride hexahydrate, sodium sulfate decahydrate, etc.), fatty acids (palmitic acid, myristic acid, etc.), aromatic hydrocarbon compounds (benzene, p-xylene, etc.), ester compounds (isopropyl palmitate, butyl stearate, etc.), alcohols (stearyl alcohol, etc.), polyalkylene glycols and the like can be used.

  In particular, when an inorganic hydrate salt is used, since there is a problem of supercooling, a normal paraffin-based latent heat storage material is preferable.

  An upper joist 17 having the same thickness as the heat storage unit 11 and the same width as the small joist 8 is overlaid on the small joist 8 of the small joist hot water mat 3. The upper joists 17 are arranged in parallel with the small joists 8 of the small joist hot water mats 3, and the whole is superposed on the small joists 8.

  FIG. 3 is a plan view showing the relationship between the small radish 8, the upper radish 17, and the heat storage unit 11 of each of the radish warm water mats 3. The upper radish 17 corresponds to the small radish 8 of the small radish warm water mat 3. The heat storage unit 11 overlaps the base 4 of the Konae hot water mat 3.

  The upper joist 17 is connected to the floor joist with the fasteners (not shown) such as screws and nails passing through the upper joist 17 and the small joist 8 of the hot water mat 3 together with the small joist 8 of the hot water mat 3. 1 is fixed.

  Further, a plurality of floor finish materials 8, 8,... Are arranged on the heat storage unit 11 and the upper joist 17, and each floor finish 8 is attached to the upper joist 17 with fasteners such as flooring staples and screws not shown. It is constructed in a fixed state.

  Therefore, in the said embodiment, since the thermal storage unit 11 is arrange | positioned and piled up on the base 4 of the small radish warm water mat 3 on the base 4 upper side of each small radish warm water mat 3 between floor finishing materials 8, The heat conducted from the joist warm water mat 3 to the floor finishing material 8 is once stored in the heat storage unit 11, and the heat released from the heat storage unit 11 is conducted to the floor finishing material 8. As a result, the heat storage effect of the heat storage unit 11 is obtained, and the heat storage effect can enhance the soaking effect on the floor finishing material 8 (floor surface), thereby suppressing the occurrence of temperature unevenness on the floor surface. .

  When constructing the floor structure, the whole upper joist 17 having the same thickness as that of the heat storage unit 11 is overlaid on the small joist 8 of each small joist hot water mat 3, and the upper joist 17 is put on the small joist hot water mat 3. Next, the heat storage unit 11 is placed next to the upper joist 17 so as to overlap the base 4 of the small joist hot water mat 3, and the upper joist 17 and the heat storage The floor finishing material 8 may be disposed on the unit 11 and the floor finishing material 8 may be applied to the upper joist 17 in a state of being fixed with fasteners such as flooring staples and screws. Thereby, it is possible to construct the heat storage unit 11 on the upper side of the radish hot water mat 3 without hindrance, and to improve the workability.

  At that time, the upper joist 17 arranged on the small joist hot water mat 3 is visible to the operator, and when the upper joist 17 is fixed and the floor finish 8 is fixed to the upper joist 17 with a fastener, Since they are performed on the visible upper joists 17, there is no mistake that the fasteners may accidentally damage the heat storage unit 11 or the hot water pipe 6 (heat generating portion) of the small joist hot water mat 3 and Reliability can be increased.

  In addition, since the heat storage unit 11 is merely placed on the radish hot water mat 3, if there is a possibility of stagnation due to deviation or the like, the squeaking noise is eliminated by arranging a buffer material. Can be.

  In the above embodiment, as shown in FIG. 5, by cutting out the upper surface of the upper joist 17 into a concave or stepped shape on a part of the upper joist 17 that overlaps the small joist 8 of the small joist hot water mat 3 in the vertical direction. You may form the notch recessed part 18 or the notch step part 19, respectively. In FIG. 5, the notched step 19 is formed at one end of the small joist 8 in the hot water mat 3 and the notched recess 18 is formed at an intermediate portion near the other end.

  In this way, when the upper joist 17 and the small joist 8 of the hot water mat 3 are overlapped and fixed to the base material with a fastener such as a screw or a nail, the bottom of the notch recess 18 or the notch step 19 It is only necessary to insert a fastener through the bottom surface and drive the fastener into the floor base 1 through the small root 8 of the small root warm water mat 3, and the length of the fastener by the depth of the notch recess 18 or notch step 19. Not only can be shortened, but also can be expected to have a remarkable effect of being stable in strength.

(Embodiment 2)
6 and 7 show the second embodiment (the same parts as those in FIGS. 1 to 5 are denoted by the same reference numerals and the detailed description thereof is omitted). The upper joist 17 is arranged so as to be orthogonal to the small joist 8 of the hot water mat 3 while being arranged in parallel with the small joist 8 of the hot water mat 3.

  That is, in this embodiment, the upper joist 17 is disposed so as to be orthogonal to the small joist 8 of the small joist hot water mat 3, and a part of the upper joist 17 is superimposed on the small joist 8. On the other hand, the heat storage unit 11 is overlaid on the base 4 of the radish hot water mat 3 and the remaining portion of the radish 8.

  FIG. 7 is a plan view showing the relationship between the small radish 8, the upper radish 17, and the heat storage unit 11 of each small radish warm water mat 3. It intersects and partly overlaps. Further, the heat storage unit 11 is placed so as to overlap the base 4 of the two radish warm water mats 3 in a state of crossing the radish 8 of the adjacent radish warm water mats 3 and straddling them. Further, an upper joist 17 is disposed immediately above the hot water pipe 6 of the small joist hot water mat 3. Other configurations are the same as those of the first embodiment.

  Also in this embodiment, the same operational effects as in the first embodiment can be achieved. In particular, in the case of this embodiment, the heat storage unit 11 is disposed not only on the base 4 of the adjacent radish warm water mat 3 but also on the radish 8, so in the floor finish 8 (floor surface), the radish warm water The heat of the heat storage unit 11 can be conducted to the portion of the base 3 that is located directly above the small joist 8 and does not have the hot water pipe 6 of the base 4. It can be further increased.

  Moreover, since the upper joist 17 is warmed by the hot water pipe 6 of the small joist hot water mat 3, in addition to the soaking effect by the heat storage material of the heat storage unit 11, the soaking effect by the upper joist 17 can be expected, and a remarkable effect is obtained. It is done.

(Other embodiments)
In the above-described embodiment, the heat storage unit 11 includes the heat storage body 14 incorporated in the frame portion 12 and the panel members 13, 13. However, the resin mat includes a microcapsule in which a latent heat storage material is enclosed. May be used. Further, a resin container or a metal container in which a latent heat storage agent is sealed may be used.

  Moreover, although the said embodiment is a case of a floor structure where floor heating is performed by the Kokona hot water mat 3 having the hot water pipe 6, the floor cooling may be performed by a cold water mat having a pipe through which cold water flows. Alternatively, floor heating and floor cooling can be switched by a mat having a pipe through which cold water flows. In the case of the cooling, it is desirable that the latent heat storage material has a temperature close to the cooling set temperature, for example, around 28 ° C. for cooling in summer.

  In addition, when performing floor heating, an electric heater may be used instead of the hot water pipe 6.

  The present invention is extremely useful because the heat storage effect of the heat storage unit can enhance the soaking effect on the floor finishing material and the workability of the heat storage unit can be improved.
