Description

  The present invention relates to a floor structure in which a latent heat storage material is accommodated and a heat storage reinforcement unit used therefor.

  In general, as one of the floor structures, in order to increase horizontal force, there is a floor assembly that increases the thickness of the floor foundation without providing joists and fastens the floor foundation directly to beams such as beams and floor beams. It is known and is stronger against horizontal force than a structure with joists, and it is accepted to omit fired beams and fired hardware.

  Specifically, a floor structure called a rigid floor is known. For example, a structural plywood with a thickness of 24 mm or more conforming to JAS (Japanese Agricultural Standards) is used as a floor base material. A flat floor structure with a floor magnification of 3 times can be obtained by flattening and fastening to the beam.

  By the way, in such a floor structure, since the floor base and the horizontal member such as a floor beam or a base are directly fastened, the floor base material itself cannot be provided with a notch. For this reason, as a structure for providing various additional functions to the floor structure, conventionally, as shown in, for example, Patent Document 1 and Patent Document 2, ventilation is made by devising a floor base peripheral portion that is not directly related to the floor structure. However, the present situation is that little consideration has been given to imparting a function to the floor surface itself of the floor structure.

  Conventionally, as a floor structure for heating, for example, in Patent Document 3, a small joist (wooden crosspiece) is formed on the upper surface of a floor structure flat plate, and a hollow portion opened upward is provided between the small joists. In this cavity, a latent heat storage material is accommodated together with a heater.

  In view of this, the present inventor has studied to provide various functions to the floor surface of the floor structure. In other words, in order to give the floor surface of the floor structure a heat storage function, by applying the technique shown in Patent Document 3 for improving the heat storage performance, the frame body is fixed to the upper surface of the face material and fixed upward. The structure is such that a hollow part opened to the surface is provided, a heat storage unit containing the latent heat storage material is provided in the cavity part, the heat storage unit is fixed on the floor surface, and the floor finishing material is constructed on the frame. Conceivable.

  However, in this case, since the heat storage unit is fixed on the floor structure, a floor structure capable of achieving a heat storage effect can be obtained, but the heat storage function is merely added while maintaining the strength of the floor structure. The synergistic effect of the heat storage unit cannot be expected on the strength of the floor structure.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The following description of the preferred embodiments is merely exemplary in nature and is in no way intended to limit the invention, its application, or its application.

  3 and 4 show a floor structure according to an embodiment of the present invention, wherein 1 is a building pillar, 2 is a horizontal member (horizontal shaft member) that extends in the horizontal direction and has an end fixed to the side surface of the pillar 1. , 3 is a floor beam as a horizontal member (horizontal shaft member) whose end is fixed to the side surface of the beam 2, and the beam 2 and the floor beam 3 include a plurality of floor bases made of plywood. The members 5, 5,... (Only one is shown) are fixed by nails N with the adjacent end faces butting the four peripheral ends on the beam 2 and the floor beam 3.

  The floor base material 5 may have a thickness of 24 mm or more, or 24 mm or less. As in the latter case, even if the thickness of the floor base material 5 is 24 mm or less, the beam 2 and the floor beam 3 (both of which are horizontal) are caused by the action of both the floor base material 5 and the heat storage reinforcing unit 10 described later. It is also possible to have a floor structure having a horizontal strength equal to or higher than that of a rigid floor to which only a floor base material 5 made of plywood having a thickness of 24 mm or more is fixed.

  Further, the floor base material 5 may have a thickness of 12 mm or more, or 12 mm or less. As in the latter case, even if the thickness of the floor base material 5 is 12 mm or less, the beam 2 and the floor beam 3 (both horizontal A floor structure having a horizontal strength equal to or higher than that of a floor structure in which only a floor base material 5 made of a plywood having a thickness of 12 mm or more is fixed to the shaft member) can be used.

  In the above description, the beam 2 and the floor beam 3 have been described as examples. However, a joist may be applied between the beam 2 (or the floor beam 3) and the floor base material 5.

  Moreover, as a horizontal shaft material such as the above-mentioned beam and joist, any material such as wooden or steel can be used.

  A plurality of panel-like heat storage reinforcement units 10, 10,... According to the embodiment of the present invention are fixed to the upper surface of the floor base material 5, and a floor finish 20 is placed on the heat storage reinforcement units 10, 10,. It is being constructed.

(Heat storage reinforcement unit)
As shown in FIGS. 1 and 2, each heat storage reinforcing unit 10 is integrally fixed to a reinforcing surface member 11 and a lower surface of the reinforcing surface member 11, and is composed of a vertical beam portion 12a and a horizontal beam portion 12b. A crosspiece 12 and a protective layer 13 fixed to the lower surface of the wooden crosspiece 12 are provided. Between the reinforcing surface member 11 and the protective layer 13, a heat storage material accommodation portion 15 is formed which is partitioned by the vertical rail portion 12 a and the horizontal rail portion 12 b of the wooden crosspiece 12. The latent heat storage material 16 is accommodated.

(Reinforcing face material)
The reinforcing face material 11 is a rectangular plate made of plywood, MDF, hard board or HDF having a thickness of 2.0 to 4.0 mm. As described above, the reinforcing surface material 11 is made of plywood, MDF, hardboard, or HDF, so that the reinforcing surface material 11 is made of the same wood-based material as the floor base material 5 and the wooden crosspiece 12. The change of the dimension according to humidity becomes equivalent, and generation | occurrence | production of the malfunction by the difference of the change can be suppressed.

  In particular, when the reinforcing face material 11 is MDF, hard board, or HDF having a high specific gravity, the strength can be ensured while considering thermal conductivity.

  When the thickness of the reinforcing surface material 11 is less than 2.0 mm, the effect of reinforcing the bending strength of the entire floor surface cannot be effectively obtained. On the other hand, when the thickness exceeds 4.0 mm, a heat insulating layer is formed, and the heat storage material accommodating portion Since the heat storage effect by the latent heat storage material 16 accommodated in 15 cannot be expected, the thickness is preferably set to 2.0 to 4.0 mm. The magnitude | size of the reinforcing surface material 11 is not specifically limited.

(Wood pier)
The wooden crosspiece 12 includes a vertical crosspiece portion 12a and a horizontal crosspiece portion 12b extending in the vertical and horizontal directions of the reinforcing surface member 11, respectively, and the vertical crosspiece portion 12a and the horizontal crosspiece portion 12b are arranged so as to be in contact with each other at right angles. Has been.

  At this time, it is preferable to form a frame part by the vertical beam part 12a and the horizontal beam part 12b in the peripheral part of the lower surface of the reinforcing surface material 11, and further, the other vertical beam part 12a and the horizontal beam part are formed inside the frame part. More preferably, 12b is arranged and partitioned so that the end surface is in contact with the inner surface of the frame portion, and the inside of the frame portion is partitioned into a plurality of spaces.

  For example, in the heat storage reinforcement unit 10 illustrated in FIG. 2, the longitudinal direction of the reinforcing face material 11 is longer than the lateral direction, and two longitudinal rails extending along the longitudinal direction on both sides of the lateral direction that is the lateral direction. Portions 12a and 12a are arranged, and two horizontal beam portions 12b and 12b extending in the width direction (width direction) of the reinforcing surface material 11 are provided between both longitudinal ends of the two vertical beam portions 12a and 12a. Arranged to form a frame. Further, a single horizontal crosspiece 12b is also disposed between the longitudinal center portions of the two vertical crosspieces 12a, 12a, and both end faces of these three horizontal crosspieces 12b, 12b,. Two spaces are defined by being in contact with the inner side surfaces of the vertical beam portions 12a, 12a and surrounded by the vertical beam portions 12a, 12a and the horizontal beam portions 12b, 12b,.

  In addition, for example, when the size of the reinforcing surface member 11 is 910 × 910 mm, the vertical beam portions 12 a, 12 a,... And the horizontal beam portion 12 b having the dimensions of height × width 12 × 12 mm as the wooden frame 12. Nine spaces may be partitioned using 12b,.

  The wooden crosspiece 12 is 10 to 15 mm in height and 10 to 100 mm in width, and preferably 11 to 13 mm in height and 13 to 50 mm in width. The reason is that if the height is less than 10 mm, the effect of the latent heat storage material 16 cannot be expected or reduced, while if it exceeds 15 mm, the effect of heating or cooling the floor surface by the latent heat storage material 16 cannot be obtained. This is because there is a problem of increasing the cost.

  In order to fix the wooden crosspiece 12 to the lower surface of the reinforcing face material 11, for example, a structural double-sided adhesive tape using an acrylic adhesive, a hot melt adhesive, a water-based vinyl urethane adhesive, a urethane adhesive, an epoxy adhesive Adhesives such as adhesives, or each means such as staples, nails and screws are used alone or in combination.

(Protective layer)
The protective layer 13 has a rectangular shape having the same size as the reinforcing face material 11 and is fixed to the lower surfaces of the vertical beam portion 12a and the horizontal beam portion 12b of the wooden frame 12. When the protective layer 13 is fixed, a heat storage material accommodation portion 15 surrounded by the vertical beam portion 12a and the horizontal beam portion 12b is partitioned between the protective layer 13 and the reinforcing surface material 11.

  Therefore, as long as the protective layer 13 can accommodate the latent heat storage material 16 in the heat storage material storage part 15, any protective sheet 13 can be used as long as it is a flexible sheet-like material. That is, when a plate-like body having a rigidity such as plywood or MDF is used as the protective layer 13, there is a possibility that unevenness may occur in the floor base material 5. In that case, the floor base material 5 and the heat storage reinforcing unit 10 Insufficient tight integration makes it impossible to expect a reinforcing effect as a floor structure.

  As the protective layer 13, a sheet with a flexible single-sided adhesive having a thickness of 0.5 mm or less in which an adhesive is applied on one side is suitably used, and the latent heat storage material 16 is interposed through the sheet with the single-sided adhesive. Is fixed integrally with the wooden crosspiece 12. As a result, the latent heat storage material 16 and the sheet with the single-sided adhesive are integrated, and the sheet with the single-sided adhesive and the wooden crosspiece 12 are also integrated. It is not moved or displaced (displaced), and transportability, handling, and workability during construction of the heat storage reinforcement unit 10 are improved.

  The sheet with the flexible single-sided pressure-sensitive adhesive can be used, for example, paper, non-woven fabric, glass cloth, plastic thin film or metal thin film, or any multilayer laminate thereof.

(Latent heat storage material)
The latent heat storage material 16 stored in the heat storage material storage unit 15 is also called PCM (Phase Change Material), and uses latent heat when a substance undergoes a phase change from a solid phase to a liquid phase, or from a liquid phase to a solid phase. When the temperature of the solid-phase latent heat storage material 16 rises and reaches its melting point, the latent heat storage material 16 starts to melt and absorbs heat of fusion from the outside. Conversely, when the temperature of the latent heat storage material 16 in the liquid phase drops and reaches the freezing point, solidification starts and the heat of solidification is released to the outside. Such heat transfer is used.

  As the latent heat storage material 16, for example, normal paraffin or inorganic hydrate which is a heat storage material is impregnated in a carrier which is a porous material such as calcium chloride hydrate or porous silica, or the same heat storage material is encapsulated. Or sealed in a bag.

  As in this embodiment, the latent heat storage material 16 used for the floor structure preferably has a melting point of 11 to 25 ° C., for example, n-hexadecane having a melting point of about 18 ° C. or n-heptadecane having a melting point of about 22 ° C. It is done. Any latent heat storage material 16 whose melting point is adjusted to 11 to 25 ° C. by modification or mixing can be used. The reason why the melting point of the latent heat storage material 16 is set to 11 to 25 ° C. is to match the assumed temperature of the indoor space when using heating in winter.

(Construction structure for floor base material of heat storage reinforcement unit)
As a structure in which a plurality of heat storage reinforcement units 10,... Having the above-described configuration are fixed to the upper surface of the floor base material 5, a plurality of heat storage reinforcement units 10, 10,. When placed on the upper surface of the floor base material 5 and fixed, and the two heat storage reinforcement units 10 and 10 adjacent to each other are viewed, the two heat storage reinforcement units 10 and 10 are not spaced from each other and the both heat storage reinforcement units 10 and 10 are present. The wooden crosspieces 12 and 12 are integrally fixed to the floor base material 5 so as to contact each other. A floor finish 20 is constructed on the heat storage reinforcement units 10, 10,.

  At that time, as shown in FIG. 4, the seam L2 between the plurality of adjacent heat storage reinforcing units 10, 10,... Is shifted from the seam L1 between the plurality of floor base materials 5 and 5.

  As a fixing means when fixing each heat storage reinforcing unit 10 to the upper surface of the floor base material 5, the nail N is fixed to the beam 2 and the floor beam 3 integrally with each other via the wooden cross section 12 of the floor reinforcing unit 10. Is most preferred. In addition, as a fixing means for fixing each heat storage reinforcing unit 10 to the upper surface of the floor base material 5, the heat storage reinforcing unit 10 is fixed to the floor base material 5 integrally with the nail N via the wooden cross section 12 of the floor reinforcing unit 10. Also good.

  Further, for example, adhesives such as double-sided pressure-sensitive adhesive tapes, hot melt adhesives, urethane adhesives, epoxy adhesives, and each means such as staples, nails and screws may be used alone or in combination. By such fixing means, the heat storage reinforcing unit 10 is firmly fixed and integrated with the floor base material 5 via the wooden crosspiece 12, and the effect of reinforcing the floor rigidity by the heat storage reinforcing unit 10 is exhibited.

(Effect of embodiment)
Therefore, in this embodiment, the plurality of heat storage reinforcement units 10, 10,... On the floor base material 5 are adjacent to the heat storage reinforcement units 10, 10 without any gaps, and the wooden rail 12 of the heat storage reinforcement units 10, 10. , 12 are integrally fixed so as to contact each other. Therefore, the reinforcing surface material 11 of each of the heat storage reinforcing units 10, 10,... Is fixed to the floor base material 5 via the wooden frame 12 in a state spaced by the height of the wooden frame 12. The reinforcing surface material 11 is fixed in a state where it is spaced from the floor base material 5 by the height of the wooden crosspiece 12. As a result, the position of the reinforcing face material 11 is shifted upward from the center in the thickness direction of the entire floor including the floor base material 5, the heat storage reinforcing unit 10, and the floor finish material 20. Since the reinforcing surface material 11 as the rigid material is located at a position away from the material 5, the bending strength of the entire floor can be increased.

  In addition, since the latent heat storage material 16 is stored in the heat storage material storage portion 15 of each heat storage reinforcement unit 10, a heat storage effect is obtained by the latent heat storage material 16.

  As a result, a floor structure having a high bending strength and a heat storage function can be obtained.

  Further, the heat storage reinforcing unit 10 is constructed with the reinforcing face material 11 disposed on the upper side, and the floor finishing material 20 is constructed thereon, so that the floor finishing material 20 is the entire reinforcing surface material 11 of the heat storage reinforcing unit 10. The floor finish 20 will not bend.

  Moreover, since the joint L2 between the plurality of adjacent heat storage reinforcement units 10 and 10 is shifted from the joint L1 between the floor base materials 5 and 5, the horizontal displacement between the floor base materials 5 and 5 is stored and strengthened. It can be reinforced by the units 10 and 10, and a stronger floor structure can be obtained.

The floor base material 5 may have a thickness of, for example, 24 mm or more and 24 mm or less. When the floor base material 5 has a thickness of 24 mm or more, the floor base material 5 is a rigid floor alone. Can be constructed, and a plurality of heat storage reinforcing units 10, 10,... Are constructed on the floor base material 5 of the rigid floor without any gaps, so that the floor base material 5 itself having a thickness of 24 mm or more has a rigid floor. Not only can the structure be obtained, but the strength can be increased by reinforcing the heat storage reinforcement units 10, 10,...

  On the other hand, when the thickness of the floor base material 5 is 24 mm or less, only the floor base material 5 made of plywood having a thickness of 24 mm or more is applied to the beam material by reinforcement by the heat storage reinforcing units 10, 10,. Has a horizontal strength equal to or higher than that of a rigid floor fixed alone, so that even if it is a floor base material 5 having a thickness of 24 mm or less, the underfloor having a thickness of 24 mm or more due to the reinforcing effect of the heat storage reinforcement units 10, 10. A strength equal to or higher than that of the floor structure on which the base material 5 is constructed can be realized.

  In this case, it is preferable to fix the beam 2 and the floor beam 3 integrally with the nail N via the wooden crosspiece 12 portion of the floor reinforcing unit 10.

  In the case of forming a rigid floor as in this embodiment, a thick structure plywood having a thickness of 24 mm to 28 mm was directly struck at 150 mm intervals on both the outer peripheral portion and the intermediate portion using N75 nails. In the floor structure (in this case, joists are not necessary), the distance between the beams is 910 mm in both the vertical and horizontal directions, and the portion interfering with the pillars and the studs is notched with the structural plywood, and the nails in the vicinity thereof are increased. Thereby, a floor magnification of 3.0 is obtained.

  As another example, a structural plywood having a thickness of 12 mm may be directly driven at 150 mm intervals in the outer peripheral portion and the intermediate portion using N50 nails for all the beams and joists. In this case, the joist is the dropped joist, the height is aligned with the top of the beam, the distance between the joists is 340 mm or less, and the part that interferes with the pillar or the stud is not provided with the structural plywood, A floor magnification of 2.0 times is obtained.

(Other embodiments)
Although the said embodiment demonstrated the case where a horizontal shaft material was used as horizontal members, such as a beam 2 and a floor beam 3, as shown in FIG. 6, for example, the floor which supports steel pulling 7 with a floor bundle It is good also as a structure (in FIG. 6, 8 is a base and 9 is a foundation), It can replace with a horizontal member and can also be a joist. Also in this case, a floor structure with less deflection can be provided by the effect of the heat storage reinforcing unit.

  Moreover, although the said embodiment is an example of the floor structure aiming at holding | maintening a horizontal force in addition to a heat storage function with respect to the floor base material 5, it is 2x4 which makes a floor panel hold | maintain a horizontal force similarly. The floor panel in the construction method may be used as a floor base material, and the heat storage reinforcement units 10, 10,... May be fixed to the top surface of the floor panel, and the same effect as the above embodiment can be achieved, and the 2 × 4 construction method. A reinforcing effect and a heat storage effect can be imparted to the floor panel.

  Since the present invention can give not only a heat storage effect but also a reinforcing effect to the floor base material, it is extremely useful and has high industrial applicability.
