土間床施工方法  Soil floor construction method
技術分野  Technical field
本発明は、 床下に空間を残さずに地盤上に床を形成して、 断熱性、 防湿性, 防音性等に優れた床とする土間床施工方法に関する。  The present invention relates to a method of constructing a floor between floors by forming a floor on the ground without leaving a space under the floor, and making the floor excellent in heat insulation, moisture resistance, sound insulation and the like.
景技術  Landscape technology
従来、 土間床の構築は、 必要に応じて盛土を施して地盤高を調節してから割 栗を敷設し、 その上にプラスチックフィルム （以下 「フ ィルム」 という） と断 熱材を順次各々別々に敷設し、 更にその上にコンク リー トを打設することに よって行っている。 断熱材としては、 通常、 硬質の合成樹脂発泡板 （以下 「発 泡板」 という） が使用されておリ、 またフィルムは防湿層として機能するもの である。  Conventionally, the construction of the floor is done by embankment as necessary, adjusting the ground height, laying the split chestnuts, and then separating the plastic film (hereinafter referred to as “film”) and the heat insulation material separately. And concrete is placed on top of it. As a heat insulating material, a rigid synthetic resin foam board (hereinafter referred to as a “foam board”) is usually used, and the film functions as a moisture-proof layer.
ところで、 割栗の上面には若干の砂をまいて表面をならすことが行われてい るが、 この砂で厚く割栗層を覆ってしまうと床が不安定になるので、 割栗間の 隙間を埋める程度のものでしかなく 割栗がその上のフィルムゃ断熱材に当接 するのは避け難い。 また、 フィルムと断熱材とを別々にしかも広い面積に亘っ て敷設することになるので、 フィルムを敷設した後の断熱材の敷設時には、 こ のフィルム上に乗って断熱材の敷設を行わざるを得ず、 更に断熱材敷設後には この上に乗ってコンク リートの打設を行わざるを得ない。  By the way, the top surface of the split chestnut is sprinkled with some sand to smooth the surface, but if this sand is thickly covered with the split chestnut layer, the floor becomes unstable. It is inevitable that the split chestnut will abut the film and insulation on it. In addition, since the film and the heat insulating material are laid separately and over a wide area, when laying the heat insulating material after laying the film, the heat insulating material must be laid on the film. It cannot be obtained, and after laying the heat insulating material, the concrete must be laid on this.
上述のように、 フィルムと断熱材が割栗上で度々踏まれることから、 敷設作 業時にフ イルムが割栗の角に当って踏み破られたり、 作業者がフ イルムを墩 破ってしまい、 所期の防湿性が得られなくなるおそれがある。 また、 断熱材と して発泡板を使用したときに、 作業老に踏まれて割れやすいだけでなく、 軽量 であることから、 破断 が風で飛散して欠落し、 新熱性を低下させる原因とも なる。 As described above, the film and the heat insulating material are often stepped on the split chestnut, so the film may hit the corner of the split chestnut during the laying work, or the worker may break the film. There is a possibility that the desired moisture resistance may not be obtained. In addition, when foamed foam is used as heat insulating material, it is not only easy to crack due to work aging, but also lightweight. As a result, the rupture is scattered by the wind and is lost, which may cause a decrease in new heat property.
*発明は、 土間床施工時のフイルム破れによる防湿性の低下及び発泡板が割 れて欠落することによる断熱性の低下を防止することを目的とする。 、 上記目的は、 地盤上に石材を敷設し、 その上に、 あらかじめ下面又は両面に フィルムを接合した発泡扳を敷並べて、 その上にコンクリ一トを打設すること によって達成されるものである。  * The invention aims to prevent a decrease in moisture resistance due to film breakage during construction of a soil floor and a decrease in heat insulation due to cracked and missing foam boards. The above-mentioned object is achieved by laying stone on the ground, laying foam on which a film is bonded on the lower surface or both surfaces in advance, and laying a concrete thereon. .
上記太発明によれば、 構築すべき土間床に防湿性を付与するためのフィルム と新熟材である発泡扳をあらかじめ接合しているので、 両者の敷設が同時に行 われることになる。 従って、 フィルムの敷設と発泡板の敷設を別々に行う従来 法に比して施工性がよい。 また、 フィルム上に直接作業者が乗ることなく フィ ルムと発泡扳を敷設できることと、 フィルムがあらかじめ発泡板と接合一体化 されていて施工時に破れにく くなつていることとから、 施工時のフィルムの損 傷による防湿性の低下を生じにくい。  According to the above-mentioned thick invention, since the film for imparting moisture-proof property to the slab to be constructed and the foam, which is a newly matured material, are joined in advance, both are laid at the same time. Therefore, the workability is better than the conventional method of laying the film and laying the foam board separately. Also, since the film and foam can be laid directly on the film without the need for workers, and because the film is pre-bonded and integrated with the foam board, it is less likely to break during construction. It is unlikely that the film becomes damaged due to film damage.
一方、 癸泡坂の下面又は両面にあらかじめフイルムを接合しておくことによ リ、 発泡板が補強され、 コンク リー トの打設時等に作業者が発泡板上に乗って も、 発泡板が割れにく くなる。 また、 万一発泡板が割れても、 破断部はフィル ムに保持されて風で飛ばされることがないので、 欠落による断熱性の大きな低 下を来たすことがない。  On the other hand, by bonding the film in advance to the lower surface or both surfaces of the Koshi Azaka slope, the foam board is reinforced, and even if an operator rides on the foam board at the time of placing concrete, the foam board is not damaged. It is difficult to crack. Also, even if the foam board breaks, the broken part is held by the film and is not blown away by the wind, so there is no significant drop in heat insulation due to the missing part.
特に、 あらかじめ発泡板の両面にフィルムを接合しておけば、 防湿屠が上面 と下面のフィルムで二重に構成され、 相乗的に高い防湿作用が得られると共 に、 両フ ィルム間に発泡板が挟まれることによリ、 発泡板の補強を高めること ができる。  In particular, if the film is bonded to both sides of the foam board in advance, the moisture-proof structure is made up of the upper and lower films, which provides a synergistically high moisture-proof effect, and foams between both films. By sandwiching the board, the reinforcement of the foam board can be enhanced.
以下、 図面を参照しつつ本発明を更に詳細に説明する。 - 第 1図は、 あらかじめ下面にフイルム 3を接合した発泡扳 4を用いて構築し た土間床の一部を示す縱断面図、 第 2図は、 あらかじめ両面にフ ィルム 3 a ， 3 b を接合した発泡板 4を用いて構築した土間床の一部を示す縱断面図、 第 3 図は、 あらかじめ下面にフィルム 3を接合した発泡板 4を敷設するときの説明 図、 第 4図及び第 5図は、 各々あらかじめ両面にフィルム 3 a ， 3 b を接合し た発泡板 4を敷設するときの説明図である。 Hereinafter, the present invention will be described in more detail with reference to the drawings. -Fig. 1 is constructed using foam 扳 4 with film 3 joined to the lower surface in advance. FIG. 2 is a longitudinal sectional view showing a part of the soil floor, which is constructed by using a foam plate 4 in which films 3a and 3b are previously joined to both sides, and FIG. Fig. 3 is an explanatory view of laying a foam board 4 to which a film 3 has been previously bonded to the lower surface. Figs. 4 and 5 show a foam board 4 to which films 3a and 3b have been previously bonded to both sides, respectively. It is explanatory drawing at the time of laying.
第 1図及び第 2図において、 6は基礎で、 まずその内側の地盤 1の高さを、 必要に応じて盛土を施して調節する。 基礎 6の外面には、 側方からの熱の逃げ を防止するため、 斬熱材 7を付設することが好ましい。 この断熱材 7は、 後述 する発泡板 4と同じ材質のものでも、 他の材質のものでもよい。  In Fig. 1 and Fig. 2, reference numeral 6 denotes a foundation. First, the height of the ground 1 inside the foundation is adjusted by embankment as necessary. It is preferable to provide a heat insulating material 7 on the outer surface of the foundation 6 in order to prevent heat from escaping from the side. The heat insulating material 7 may be made of the same material as the foam plate 4 described later, or may be made of another material.
基礎 6の内側の地盤 1上に石材 2を敷設する。 石材 2としては、 例えば割 栗、 砂利、 小石等が使用される。  The stone 2 is laid on the ground 1 inside the foundation 6. As the stone material 2, for example, chestnut, gravel, pebbles, etc. are used.
石材 2の層の厚みは、 地盤 1の硬さ等に応じて適宜定めればよい。 また、 石 材 2の曆上には砂 8をまいて、 石材 2間の隙間を埋め、 上面をほぼ平坦にする ことが好ましい。 このようにすることによって、 次に敷設するフィルム 3又は フ ィルム 3 a ， 3 b 付の発泡板 4を水平に設置しやすくなリ、 床面を水平にし やすくなる。  The thickness of the layer of the stone 2 may be appropriately determined according to the hardness of the ground 1 and the like. Further, it is preferable that sand 8 is spread on the surface of the stone 2 so as to fill the gap between the stones 2 and the upper surface thereof is made substantially flat. By doing so, the film 3 or the foam plate 4 with the films 3a and 3b to be laid next can be easily installed horizontally, and the floor can be easily made horizontal.
次に、 あらかじめ下面にフ ィルム 3又は両面にフィルム 3 a ， 3 b を接合し た発泡板 4を石材 2上に敷設する。  Next, a foam plate 4 having the film 3 on the lower surface or the films 3a, 3b on both surfaces is laid on the stone 2 in advance.
フィルム 3 , 3 a , 3 b としては、 厚みが 20〜100 程度で、 例えばボリエ チレン、 ボリプロピレン、 ポリ塩化ビニル等にエチレン一薛酸ビニル共重合体 やエチレンーァクリル酸共重合体等のヒ一トシール性プラスチックをコーティ ング又はラ ミ ネー ト したものが好適に使用できる。 このようなフ ィルム 3 ， 3 a ， 3 b とすると、 発泡板 4への接合を、 上記ヒー トシール性プラスチッ ク 層の熱融着を利用して行うことができる。 但し、 他のフィルムを、 接着剤等に よって発泡板 4に接合するようにしてもよい。 癸泡扳 4は、 床面からの荷重に耐えるよう硬質のものであることが好まし い。 具体 _的には、 例えばポリ スチレン、 ポリウレタン、 ポリエチレン、 ポリ塩 化ビニル、 フエノール楫脂等の発泡体や、 これらのプラスチックに無機充塡材 を添加した発泡体を挙げることができる。 最も好ましくはスタイ口フォーム 〔商品名） 等の押出発泡ポリ スチレン扳である。 発泡板 4は、 下面のフ ィルム 3又は両面のフ ィルム 3 a ， 3 b によって水分から保護されるので、 ことさら スキンボードとせず、 カッ トボードでもよい。 また、 癸泡扳 4は、 荷重に耐え るよう、 2 kgf/cm 2 程度以上の圧縮強さがあることが好ましい。 Films 3, 3a and 3b have a thickness of about 20 to 100, for example, such as polyethylene, polypropylene, polyvinyl chloride, etc. A material obtained by coating or laminating a heat-sealable plastic can be suitably used. With such films 3, 3a and 3b, bonding to the foamed plate 4 can be performed by utilizing the heat sealing of the heat-sealable plastic layer. However, another film may be joined to the foam plate 4 with an adhesive or the like. It is preferable that Kishibu 4 be rigid to withstand the load from the floor. Specific examples include foams such as polystyrene, polyurethane, polyethylene, polyvinyl chloride, and phenol caustic, and foams obtained by adding an inorganic filler to these plastics. Most preferably, it is an extruded foamed polystyrene such as Styrofoam [trade name]. Since the foam plate 4 is protected from moisture by the film 3 on the lower surface or the films 3a and 3b on both surfaces, a cut board may be used instead of a skin board. In addition, it is preferable that Kishifoam 4 has a compressive strength of about 2 kgf / cm 2 or more so as to withstand a load.
土間床においては、 室内の温度が過度に高くなつた場合、 ある程度地盤 1へ と熱を！ ^がし、 基礎外面の断熱材 7の付設とも相俟って地盤 1に蓄熱し、 室内 の温度が下ったときにこれを室内へ放出する機能を有することが好ましい。 このことから、 発泡板 4は、 過度に断熱性の高い厚いものよリ、 熱伝導率が 0. 0 15 〜0 . 040kca^Hr ' °C 程度で、 厚みが 20〜100mm 、 最適には 25〜50mm程度 であることが好ましい。  If the temperature inside the room rises excessively on the clay floor, heat to the ground 1 to some extent! However, it is preferable to have a function of storing heat in the ground 1 in combination with the provision of the heat insulating material 7 on the outer surface of the foundation and releasing the heat into the room when the temperature of the room decreases. From this, the foamed board 4 should have a thermal conductivity of about 0.015 to 0.040 kca ^ Hr '° C, a thickness of 20 to 100 mm, and optimally 25 It is preferably about 50 mm.
あらかじめ下面にフィルム 3又は両面にフィルム 3 a ， 3 b を接合した発泡 板 4の敷設は、 単に相降接する発泡板 4の側面同志を突き合わせて並べるだけ でもよい。 し力 し、 齄目部の防湿性を高めるには、 次のようにすることが好ま しい。  When laying the foam plate 4 in which the film 3 is bonded to the lower surface or the films 3a and 3b are bonded to both surfaces in advance, the side surfaces of the foam plates 4 which are in contact with each other may be simply arranged side by side. In order to increase the moisture resistance of the eye part, it is preferable to do the following.
まず、 第 3図及び第 4図に示されるように、 フ ィ ルム 3又はフ ィ ルム 3 a (フ ィルム 3 b でもよい） を発泡扳 4ょリ外方へ突出させておき、 この上に降 接するフ ィルム 3又はフ ィルム 3 a ， 3 b 付の尧泡板 4を重ねながら敷設すれ ば、 幾目部の防湿性を高めることができる。 また、 第 5図に示されるように、 フ ィルム 3 a ， 3 b の両者を発泡板 4ょリ外方に突出させ、 発泡板 4同志の突 き合わせ部をその突出部で上下から覆うようにすると、 更に幾目部の防湿性を 高めることができる。 上述のようにして敷設したフィルム 3又はフ イルム 3 a 7 3 b 付の発泡板 4 上にコンク リート 5を打設し、 更にその上面をならしモルタル 9で仕上げて土 間床の構築を完了する。 床面積が広い場合、 フ ィルム 3又はフ ィルム 3 a ， 3 b 付の発泡板 4上に配飭した後にコンクリート 5の打設を行うことが好まし い。 First, as shown in Fig. 3 and Fig. 4, film 3 or film 3a (or film 3b) may be protruded outward from the foam 4 and then placed on top of it. By laying while stacking the film 3 or the foam plate 4 with the films 3a and 3b to be in contact with each other, it is possible to enhance the moisture resistance of the joints. Also, as shown in FIG. 5, both films 3a and 3b are projected outside the foam plate 4 so that the butted portions of the foam plates 4 are covered with the projected portions from above and below. By doing so, it is possible to further enhance the moisture resistance of the mesh portions. The concrete 5 is cast on the foam plate 4 with the film 3 or film 3a7 3b laid as described above, and the upper surface is leveled and finished with mortar 9 to complete the construction of the earthen floor. I do. If the floor area is large, it is preferable to place concrete 5 after arranging it on the foam plate 4 with the film 3 or the films 3a and 3b.
尚、 第 1図及び第 2図において、 10は基礎 6部分の仕上げモルタル、 1 1は土 台、 1 2は外壁材、 13はコーキングである。  In FIGS. 1 and 2, 10 is a mortar for finishing 6 parts of the foundation, 11 is a base, 12 is an outer wall material, and 13 is a caulking.
本発明によれば、 施工時のフィルム 3又はフ ィルム 3 a , 3 b の損傷によつ て床の防湿性が大きく低下したり、 発泡板 4の割れによって断熱性が大きく低 下することがなく、 設計通りの快適な室内環境が得やすい。 また、 施工能率も 向上し、 作業時間の短縮も図れるものである。  According to the present invention, the moisture resistance of the floor is greatly reduced due to damage to the film 3 or the films 3a, 3b during construction, and the heat insulation is significantly reduced due to cracks in the foam plate 4. It is easy to obtain a comfortable indoor environment as designed. It also improves construction efficiency and shortens work time.
