Description

【０００１】
【発明の属する技術分野】
この発明は、コンクリート製の駆体構造に関し、とくに、冷暖房の高効率化を図った潜熱蓄熱式の床スラブ構造および施工方法に関する。
【０００２】
【従来の技術】
省エネルギーシステムの一環として、安価な夜間電力によって得た冷温熱を蓄熱媒体に蓄えておき、その冷温熱を昼間に利用することで冷暖房の効率化を図る蓄熱システムが知られている。なかでも、蓄熱容量が大きく蓄熱槽の小型化が可能な潜熱蓄熱材を利用した蓄熱システムが広く採用され始めている。
【０００３】
従来の潜熱蓄熱材を利用した蓄熱システムでは、夜間においてボイラやヒートポンプなどの熱源機を駆動して得た冷温熱を熱伝達媒体を介して蓄熱槽に蓄熱する。昼間においては蓄熱槽に蓄熱された冷温熱を前記熱伝達媒体を介して熱交換器や駆体（コンクリートスラブなど）に放熱して冷暖房負荷の軽減を図る。
【０００４】
【発明が解決しようとする課題】
このような従来の潜熱蓄熱材を利用した蓄熱システムでは蓄熱する場所と放熱する場所が異なり、この両者間の熱のやりとりを熱伝達媒体を介して間接的に行う必要があるため、蓄熱槽と熱源機および熱交換器を接続する熱伝達媒体の循環経路に配管やポンプなどを配設するのに甚大な時間やコストを必要とするという問題があった。また熱搬送時の熱損失は避けられないという問題もあった。
【０００５】
この発明は前述した従来の問題点に鑑みなされたもので、その目的は、蓄熱・放熱が効率的に行えるとともに、蓄熱槽やその周辺装置を設ける必要がない簡易な構造の潜熱蓄熱式の床スラブ構造および施工方法を提供することにある。
【０００６】
【課題を解決するための手段】
この発明の請求項１に記載の潜熱蓄熱式の床スラブ構造は、コンクリート下面の凹凸と波型デッキプレートとが密着されており、その波型デッキプレートの下面に平鋼板などの封止板が接合され、前記波型デッキプレートと前記封止板で挟まれた空間に潜熱蓄熱量の大きい蓄熱材が封入されていることを特徴とする。
【０００７】
請求項２に記載の潜熱蓄熱式の床スラブ構造は、請求項１において、前記波型デッキプレートと封止板とに挟まれてなる空間の一部を送風空間とすることを特徴とする。
【０００８】
請求項３に記載の潜熱蓄熱式の床スラブ構造の施工方法は、波型デッキプレートの下面に平鋼板などの封止板を接合し、この両者で挟まれた空間に潜熱蓄熱量の大きい蓄熱材を封入するとともに、前記波型デッキプレートの上面に床スラブのコンクリートを打設することを特徴とする。
【０００９】
請求項４に記載の潜熱蓄熱式の床スラブ構造の施工方法は、波型デッキプレートの下面に平鋼板などの封止板を接合し、この両者で挟まれた空間に潜熱蓄熱量の大きい蓄熱材を封入するとともに、床のコンクリートスラブの下面に一体的に配置された前記波型デッキプレートと同型の他の波型デッキプレートの下面凹凸に前記波型デッキプレートの上面凹凸をはめ合わせて接合することを特徴とする。
【００１０】
【発明の実施の形態】
この発明の実施例に関する潜熱蓄熱式の床スラブの基本構造を図１ないし図２に示す。コンクリートスラブ１の下面の凹凸と波型デッキプレート２とが密着されており、その波型デッキプレート２の下面に平鋼板３が接合されている。前記波型デッキプレート２と前記平鋼板３で挟まれた空間には、例えばコスト・蓄熱容量・耐久性に優れたパラフィン系の潜熱蓄熱材４が封入されており、この潜熱蓄熱材４は所定の添加剤を加えることによって流動性が低く保たれている。
【００１１】
つぎに、この床スラブ構造の施工方法について説明する。波型デッキプレート２の下面凸部に所定の大きさの平鋼板３を溶接または接着することで両者を一体化する。この両者によって挟まれてなる空間に前記潜熱蓄熱材４を充填するともに、その両端に図示しない平鋼板などの封止板を溶接または接着して密封する。次に、前述の波型デッキプレート２を型枠としてその上面にコンクリートスラブ１を打設して蓄熱式の床スラブが形成される（図１）。なお、前記平鋼板３はこれに限るものではなく要は封止板としての役割を果たせるものであればよい。
【００１２】
別の施工方法について説明する。この方法では、波型デッキプレート２と平鋼板３および潜熱蓄熱材４からなる蓄熱ユニットを床スラブの工事とは別個に製作しておく。また、このユニットの波型デッキプレート２と同じ波型デッキプレート５を型枠として用いて床のコンクリートスラブ１を打設する。そして波型デッキプレート５の下面凹凸に前記波型デッキプレート２の上面凹凸をはめ合わせて両者を接続する（図２）。この両者の接続は、溶接・ネジ止め・磁石の吸引力などの方法による。また、前記波型デッキプレート５と前記波型デッキプレート２の形状は完全に一致する必要があるため、同一メーカの同一型番の波型デッキプレートを用いることが望ましい。
【００１３】
この発明の潜熱蓄熱方式の床スラブ構造の利用方法を説明する。床スラブの上方または下方には装飾・防音・断熱としての役割を果たす天井・床部材が配設されるが、通常は両者の間に配線・配管を自由に行えるような空間が設けられる。こうして設けられた床スラブの上面に接するフリーリアクセス空間、または床スラブの下面に接する天井裏空間などの所定位置に冷温風を送風する装置を設置しておく。これを夜間（例えば２２時から翌日の６時まで）に駆動させて前記空間の両方もしくは片方に冷温風を通して床スラブに蓄熱する。このとき、床スラブの上面（下面）を流れる冷温風の冷温熱は、コンクリートスラブ１と潜熱蓄熱材４の両方に蓄積される。この両者は空気層を介さず密着されているため熱伝達性が極めて良好である。そのため両者への熱損失の少ない敏速な同時蓄熱が可能であり、蓄熱のための消費電力が低減される。またコンクリートスラブ１と潜熱蓄熱材４の相乗効果によって、コンクリートスラブ１のみを蓄熱する場合に比べて飛躍的に大量の蓄熱が可能である。
【００１４】
ここで、床スラブの１ｍ2 あたりの蓄熱量を具体的数値を用いて試算する。この計算で用いた床スラブの断面を図３に示す。波型デッキプレート２の凸部の上端幅は１１０ｍｍであり、下端幅は１４２ｍｍである。波型デッキプレート２の凹部の上端幅は１２０ｍｍであり、下端幅は８８ｍｍである。コンクリートスラブの厚さは、波型デッキプレートの凸部上に８５ｍｍ、凹部上に１６０ｍｍ（７５ｍｍ＋８５ｍｍ）である。コンクリートの容積比熱を４６０ｋｃａｌ／ｍ3 ・℃、温度変動が５℃として計算すると、床スラブの１ｍ2 あたりのコンクリートの蓄熱量は２７６ｋｃａｌである。また潜熱蓄熱材としてパラフィン（４０ｋｃａｌ／ｋｇ）を用い、これが床スラブ１ｍ2 あたり３５ｋｇ収容されているとして計算すると、床スラブの１ｍ2 あたりの潜熱蓄熱材の蓄熱量は１４００ｋｃａｌである。よって、床スラブは１ｍ2 あたり１６７６ｋｃａｌの蓄熱が可能である。これは、コンクリートスラブのみの場合の約６倍の蓄熱量である。
【００１５】
前記実施例の応用として、波型デッキプレート２と平鋼板３に挟まれてなる空間の一部を冷温風の送風ダクト６として用いる方法がある。その一例を図４に示す。潜熱蓄熱材が充填された部分と前記送風ダクト６とが交互に配置されている。この方法は床の上方または下方に送風する空間がない場合に有効である。また、冷温風と床スラブとの接触面積を大きくして熱交換の高効率化を図る必要がある場合にも有効である。
【００１６】
【発明の効果】
この発明の蓄熱式の床スラブは、潜熱蓄熱材とコンクリートスラブが波型デッキプレートを介して密着しており、両者の間に空気層がないため熱伝達性が極めて良好である。そのため両者への熱損失の少ない敏速な同時蓄熱が可能であり、蓄熱のための消費電力が低減される。またコンクリートスラブと潜熱蓄熱材との相乗効果によって、コンクリートスラブのみを蓄熱する場合に比べて飛躍的に大量の蓄熱が可能である。
【００１７】
また、床スラブを蓄熱媒体として用いるため、特別に蓄熱槽やその周辺装置を設置する必要がなく、駆体蓄熱と同じ要領で非常に簡単に蓄熱できることからイニシャルコストやランニングコストの低減化および工期短縮が図れる。
【００１８】
さらには、潜熱蓄熱材を封入した波型デッキプレートをそのまま型枠として使用したり、床スラブにはめ込み接合して使用できるため、省スペース性・施工性等に優れる。

BACKGROUND OF THE INVENTION
The present invention relates to a concrete body structure, and more particularly, to a latent heat storage type floor slab structure and a construction method for improving the efficiency of air conditioning.
[0002]
[Prior art]
As a part of the energy saving system, a heat storage system is known in which cold / hot energy obtained by inexpensive nighttime electric power is stored in a heat storage medium, and the cold / hot heat is used in the daytime to improve the efficiency of air conditioning. Among them, a heat storage system using a latent heat storage material having a large heat storage capacity and capable of downsizing a heat storage tank has been widely adopted.
[0003]
In a conventional heat storage system using a latent heat storage material, cold heat obtained by driving a heat source machine such as a boiler or a heat pump at night is stored in a heat storage tank via a heat transfer medium. In the daytime, the cooling / heating load stored in the heat storage tank is radiated to the heat exchanger and the driving body (concrete slab, etc.) through the heat transfer medium to reduce the cooling / heating load.
[0004]
[Problems to be solved by the invention]
In such a conventional heat storage system using a latent heat storage material, the place where heat is stored differs from the place where heat is dissipated, and it is necessary to exchange heat between the two indirectly via a heat transfer medium. There has been a problem that enormous time and cost are required to arrange pipes and pumps in the circulation path of the heat transfer medium connecting the heat source device and the heat exchanger. There is also a problem that heat loss during heat transfer is unavoidable.
[0005]
The present invention has been made in view of the above-described conventional problems, and its purpose is to efficiently store and dissipate heat and to have a simple structure of a latent heat storage type floor that does not require a heat storage tank and its peripheral devices. It is to provide a slab structure and a construction method.
[0006]
[Means for Solving the Problems]
In the latent heat storage type floor slab structure according to claim 1 of the present invention, the irregularities on the bottom surface of the concrete and the corrugated deck plate are in close contact, and a sealing plate such as a flat steel plate is provided on the bottom surface of the corrugated deck plate. A heat storage material having a large latent heat storage amount is sealed in a space that is joined and sandwiched between the corrugated deck plate and the sealing plate.
[0007]
A latent heat storage type floor slab structure according to a second aspect is characterized in that, in the first aspect, a part of the space sandwiched between the corrugated deck plate and the sealing plate is used as an air blowing space.
[0008]
The construction method of the latent heat storage type floor slab structure according to claim 3 is characterized in that a sealing plate such as a flat steel plate is joined to the lower surface of the corrugated deck plate, and the heat storage with a large latent heat storage amount is sandwiched between the two. A material is enclosed, and concrete of a floor slab is placed on the top surface of the corrugated deck plate.
[0009]
The construction method of the latent heat storage type floor slab structure according to claim 4 is a method of joining a sealing plate such as a flat steel plate to the lower surface of the corrugated deck plate and storing a large amount of latent heat storage in a space sandwiched between the two. In addition to encapsulating the material, the top surface unevenness of the corrugated deck plate is joined to the bottom surface unevenness of another corrugated deck plate of the same type as the corrugated deck plate that is integrally disposed on the bottom surface of the concrete slab of the floor. It is characterized by doing.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
A basic structure of a latent heat storage type floor slab according to an embodiment of the present invention is shown in FIGS. The corrugations on the lower surface of the concrete slab 1 are in close contact with the corrugated deck plate 2, and the flat steel plate 3 is joined to the lower surface of the corrugated deck plate 2. A space between the corrugated deck plate 2 and the flat steel plate 3 is filled with, for example, a paraffin-based latent heat storage material 4 excellent in cost, heat storage capacity, and durability, and the latent heat storage material 4 is predetermined. The fluidity is kept low by adding the additive.
[0011]
Next, the construction method of this floor slab structure will be described. The flat steel plate 3 having a predetermined size is welded or bonded to the lower surface convex portion of the corrugated deck plate 2 to integrate both. The space between the two is filled with the latent heat storage material 4, and a sealing plate such as a flat steel plate (not shown) is welded or bonded to both ends of the space to seal it. Next, a concrete slab 1 is placed on the upper surface of the corrugated deck plate 2 as a mold to form a heat storage type floor slab (FIG. 1). The flat steel plate 3 is not limited to this and may be any material that can serve as a sealing plate.
[0012]
Another construction method will be described. In this method, a heat storage unit composed of the corrugated deck plate 2, the flat steel plate 3, and the latent heat storage material 4 is manufactured separately from the floor slab construction. Also, the floor concrete slab 1 is placed using the same corrugated deck plate 5 as the corrugated deck plate 2 of this unit as a formwork. Then, the upper surface unevenness of the corrugated deck plate 2 is fitted to the lower surface unevenness of the corrugated deck plate 5 to connect them (FIG. 2). The connection between the two is based on methods such as welding, screwing, and magnetic attraction. In addition, since the shape of the corrugated deck plate 5 and the corrugated deck plate 2 need to completely match, it is desirable to use corrugated deck plates of the same manufacturer and the same model number.
[0013]
A method of using the latent heat storage type floor slab structure of the present invention will be described. A ceiling / floor member serving as decoration, soundproofing, and heat insulation is disposed above or below the floor slab, but usually a space is provided between them so that wiring and piping can be freely performed. A device that blows cool / warm air in a predetermined position such as a free access space in contact with the upper surface of the floor slab or a ceiling space in contact with the lower surface of the floor slab is installed. This is driven at night (for example, from 22:00 to 6:00 on the next day), and heat is stored in the floor slab through cool air in one or both of the spaces. At this time, the cold / hot air flowing through the upper surface (lower surface) of the floor slab is accumulated in both the concrete slab 1 and the latent heat storage material 4. Since both of them are in close contact with each other without an air layer, heat transferability is extremely good. Therefore, rapid simultaneous heat storage with little heat loss to both is possible, and power consumption for heat storage is reduced. Further, due to the synergistic effect of the concrete slab 1 and the latent heat storage material 4, a large amount of heat can be stored compared to the case where only the concrete slab 1 is stored.
[0014]
Here, the heat storage amount per 1 m 2 of the floor slab is estimated using specific numerical values. A cross section of the floor slab used in this calculation is shown in FIG. The upper end width of the convex portion of the corrugated deck plate 2 is 110 mm, and the lower end width is 142 mm. The upper end width of the concave portion of the corrugated deck plate 2 is 120 mm, and the lower end width is 88 mm. The thickness of the concrete slab is 85 mm on the convex part of the corrugated deck plate and 160 mm (75 mm + 85 mm) on the concave part. When the specific volume heat of concrete is calculated as 460 kcal / m 3 · ° C. and the temperature fluctuation is 5 ° C., the heat storage amount of concrete per 1 m 2 of the floor slab is 276 kcal. The use of a paraffin (40 kcal / kg) as the latent heat storage material, which is calculated as being 35kg per floor slab 1 m 2 housing, heat storage quantity of latent heat storage material per 1 m 2 of the floor slab is 1400Kcal. Therefore, the floor slab can store 1676 kcal per m 2 . This is about 6 times the amount of heat stored in the case of concrete slabs only.
[0015]
As an application of the above-described embodiment, there is a method in which a part of a space sandwiched between the corrugated deck plate 2 and the flat steel plate 3 is used as a blow duct 6 for cold / hot air. An example is shown in FIG. The portions filled with the latent heat storage material and the air duct 6 are alternately arranged. This method is effective when there is no space for blowing air above or below the floor. It is also effective when it is necessary to increase the contact area between the cool / warm air and the floor slab to increase the efficiency of heat exchange.
[0016]
【The invention's effect】
In the heat storage type floor slab of the present invention, the latent heat storage material and the concrete slab are in close contact with each other via the corrugated deck plate, and since there is no air layer between them, the heat transfer property is extremely good. Therefore, rapid simultaneous heat storage with little heat loss to both is possible, and power consumption for heat storage is reduced. In addition, due to the synergistic effect of the concrete slab and the latent heat storage material, a large amount of heat can be stored compared to the case of storing only the concrete slab.
[0017]
In addition, because floor slabs are used as a heat storage medium, there is no need to install a special heat storage tank or its peripheral equipment, and it is very easy to store heat in the same manner as the heat storage of the precursor. It can be shortened.
[0018]
Furthermore, since the corrugated deck plate in which the latent heat storage material is enclosed can be used as it is as a formwork, or can be used by fitting it into the floor slab, it is excellent in space saving and workability.
