Description

【０００１】
【発明の属する技術分野】
本発明は、建築用土組成物等に係り、特に、建築物の屋根部分や壁等の下地材としての建築用土組成物及び建築用土の製造方法に関する。
【０００２】
【従来の技術】
従来、建物屋根部の主棟、隅棟等に設置される棟瓦あるいは隅瓦等の安定と、雨水等からの防水のために屋根土を各棟部等に台状に設置してその上面にそれらの棟瓦や隅瓦等が載置される。従来、これらの屋根土は、施工現場で粘土質の土に適宜の大きさに切断した切り藁等を混合して水で混練し、これを各棟部に施工して乾燥後その表面を漆喰で仕上げて建物内部に雨水が浸潤しないように保護していた。ところが、この方法では、屋根土の付設施工と、一定の乾燥期間をおいた後の漆喰仕上げとの２回の施工に手数と工期を必要とし施工効率が劣る。これに対し、近年、石灰、砂、粘土、麻つた等の原料を所定の割合で水で混練した混練材を包装袋に袋詰めした屋根土が提案され（例えば特公平５−６３４２６号）、袋詰めの状態で略５０日程度保存でき、施工後も漆喰による表面仕上げを不要とする点から用いられていた。ところが、さらに、この第２の方法による屋根土も、粘度成分が水分を含有し、現場施工後、屋根土が乾燥する際に粘土内の水分の蒸発で粘土が収縮し表面から内部へ亀裂が発生し、この亀裂から雨水が浸潤するために水密性が低く、しだいに屋根土が風化して屋根面の主棟、隅棟、あるいは谷部等が雨漏りして耐用年数が低くなりやすい問題があった。
【０００３】
【発明が解決しようとする課題】
これに対し、特開平９−１００１４９号において、出願人は、粘土を用いることなく、袋詰め状態で長期使用ができ、現場作業を簡略化できてしかも施工後も乾燥による亀裂が生じにくい屋根土を先に提案した。しかしながら、この特開平９−１００１４９号の屋根土では、素材に加水して混練し、所要時間後に固さ調整のためにローラ等により加圧する必要があるから、加圧工程用のモータ、ローラ等の加圧装置が必要であるとともに、加圧工程自体が素材の混練、袋詰め以外に必要となり、作業時間がかかり作業コスト、製品コスト増を招くきらいがあった。また、素材に消石灰を用いる場合には、加圧後密封状態で袋詰めしていてもどうしても二酸化炭素との反応により経時的に硬化してしまい、作業現場での使用時に袋を破って取り出す際に袋の内面にべったり付着した状態となって反転させても袋から排出しにくく現場作業性を損なううえに、硬化により施工時に構造材との接着性が劣るという問題があった。
【０００４】
本発明は、上記従来の課題に鑑みてなされたものであり、その１つの目的は、加圧工程を必要とすることなく施工後の土にクラックを生じさせず、しかも簡単な構成により、安価な材料、施工コストとし、現場での使用時の土の取り出しも簡単で、さらに、構造材との良好な接着性を保持し得る建築用土組成物及び建築用土の製造方法を提供することにある。また、本発明の他の目的は、製品化後の使用に耐え得る日持ちを飛躍的に長くさせることのできる建築用土組成物及び建築用土の製造方法を提供することである。

【特許文献２】特開平９−１００１４９号
【０００５】
【課題を解決するための手段】
上記目的を達成するために、本発明は、生石灰と、少なくとも生石灰よりも多い重量の水と、古紙を適宜の大きさに切断した切断古紙と、骨材と、を含み、これらを混練して急冷後非通気性袋に密封収納させた建築用土組成物から構成される。このほかに、適量の撥水材、ガラス繊維等のつなぎ材を混合してもよい。また、施工時の構造材に合わせて適宜、黒色系を出すための顔料を混合してもよい。
【０００６】
また、本発明は、重量比で、生石灰１に対し、骨材０〜５．５、古紙０．１〜１、水１．７５〜１０と、適宜の量の撥水材と、つなぎ材と、を混練し、急冷後、非通気性袋に密封収納させた建築用土組成物から構成される。建築用土の例えば屋根土屋あるいは塗壁用等の具体的な適用のしかた、及び固さ調整のために、骨材量と水量を変化させる。骨材としては砂と、白色の色出しと滑面仕上げのための炭酸カルシウムと、を用いるとよい。古紙は、多くとも生石灰量（重量）と同じ程度がよく、多過ぎると生石灰と骨材との硬化結合がかえって阻害されるおそれが生じる。水は生石灰との消化発熱反応と、古紙への吸水量を加味して消石灰と異なり、少なくとも生石灰量に対して重量比で１．７５以上が好ましい。また、非通気性袋詰めして保管、出荷、現場使用等の経時要素を考慮しても生石灰の量の１０倍（重量比）を越えない量であるのが好ましい。
【０００７】
さらに、本発明は、生石灰と、少なくとも生石灰よりも多い重量の水と、古紙を適宜の大きさに切断した切断古紙と、骨材と、撥水材と、つなぎ材と、を攪拌混練後、急冷し、非通気性袋詰めして密封してなる建築用土の製造方法から構成される。
【０００８】
【発明の実施の形態】
以下、本発明の建築用土組成物の実施形態についてその製造方法を含め図面を参照しつつ説明する。本発明の建築用土組成物は、建築物の屋根部分や壁等の下地材としての建築用土として適用される組成物である。
【０００９】
本発明の建築用土組成物は、生石灰と、少なくとも生石灰よりも多い重量の水と、古紙を適宜の大きさに切断した切断古紙と、骨材と、を含み、これらを混練して急冷後非通気性袋に密封収納させて構成される。生石灰（ＣａＯ）は、破砕した石灰石（ＣａＣｏ３）を焼成釜中で例えば１０００℃以上程度で焼成して熱分解し、粉体化したものである。
【００１０】
建築用土の組成物の内容構成は、下記の表１のような構成が好ましい。
【表１】

【００１１】
実施形態において、建築用土組成物を用いた建築用土は、生石灰と、少なくとも生石灰よりも多い重量の水と、古紙を適宜の大きさに切断した切断古紙と、骨材と、撥水材と、つなぎ材と、を攪拌混練後、急冷し、非通気性袋詰めして密封して得られる。図１は、本発明の一実施形態としての建築用土の製造工程を示しており、生石灰と、骨材としての炭酸カルシウムと古紙と水をミキサーに投入して５分程度、攪拌混練し、その後、水ジャケット内を搬送させて急冷し、合成樹脂製等の非通気性袋に袋詰めして密封させるものである。
【００１２】
古紙は日常的に各種事務所、事業所、流通業者、一般家庭等から排出される新聞、雑誌、ちらし、紙くず、その他の紙製品を破砕機で例えば１ｃｍ×１ｃｍ程度の適宜の大きさに破砕したものであり、破砕後のサイズ自体はそれ以上、あるいはそれ以下の大きさでもよく限定されない。裁断機で同等大きさに裁断してもよい。古紙は吸水性、保水性を有し、かつ、紙として製品化される際の種々の接着材あるいは接着機能物質を含み、かつパルプ繊維を含む。したがって、古紙を生石灰やその他の骨材と、加水下で攪拌混練すると生石灰の消化作用により、例えば１００℃以上程度まで発熱するからその熱により破砕切断した古紙はどろどろの状態で溶けて土の内部に浸潤し、さらに、万遍なく組成物内に分布、存在することにより、それらの接着剤等と、パルプ繊維成分とにより屋根土や塗壁用材料として適用した際にそれ自体の結合性に優れ、クラックを生じさせないようにさせる。
【００１３】
骨材は、一般的に用いられる砂でもよいし、炭酸カルシウム（ＣａＣｏ３）粉、あるいはこれらの混合物でもよい。炭酸カルシウム粉は、石灰石を粉砕したものであり、水に溶けにくく塗壁材等に用いると滑面状の仕上げ表面が得られてきめの細かい仕上げ面を形成できる。骨材として砂を主に用いる場合には屋根土として好適に適用し得る。
【００１４】
水は、少なくとも生石灰よりも多い重量の水が加えられる。したがって、投入する骨材量を勘案しても、つきたての餅程度の粘度とフロー度で形成される。この際、実施例のように重量比で、生石灰１に対し、水１．７５〜１０程度が好ましい。このように、例えば消石灰（Ｃａ（ＯＨ）２）などに比較してより大量の水を加えるのは、古紙が相当量の水分を吸水しかつ保水する点と、生石灰の消化を行なわせ、その後の非通気性袋内への袋詰めだけで消化を完成させるためである。一般に、消石灰生成のためにはスクリューコンベア等を用いた消火装置と、消化後の養生時間が必要であり、その設備、作業コストを反映して消石灰単体で流通段階で入手すると生石灰の約２倍のコストがかかる。したがって、生石灰から直接に他の骨材、古紙等とともに加水下で混練することにより製造コストを低減させると同時に、古紙の吸水・保水性と、生成された土の強度、接着性向上、作業性向上等を達成し得る。
【００１５】
建築用土を屋根土として適用する場合には、骨材として砂を多く用いて白色と滑面性保持をも行なう炭酸カルシウム量を少なくして低コスト化を実現し得る。なお、黒色の土色とする場合には適宜の顔料を用いるとよい。また、防水用の撥水材（例えば商品名、ルーブリンス）や土の強度補強のためにガラス繊維等のつなぎ材を混入するとよい。一方、建築用土を塗壁用として使用する場合には、施工時の表面の滑面性保持のために、砂を用いずに炭酸カルシウム量を増量させるとよい。
【００１６】
建築用土組成物は、生石灰と、少なくとも生石灰よりも多い重量の水と、古紙を適宜の大きさに切断した切断古紙と、骨材と、を含み、これらを混練して急冷後非通気性袋に密封収納させて構成することにより、上記のような機能とともに、古紙の保水性により長期にわたって袋詰めした建築用土の使用に耐え得ないまでの硬化を防止し、製品寿命を長くさせることができる。また、例えば１年程度の密封状態での保管によっても古紙の存在により合成樹脂製の袋の内面に土が密着せず、したがって、土を施工現場で使用する際に袋を反転させると、簡単に内容物の土が排出され、作業性を良好にさせる。
【００１７】

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a construction soil composition and the like, and more particularly to a construction soil composition as a base material for a roof portion and a wall of a building and a method for producing the construction soil.
[0002]
[Prior art]
Conventionally, roof soil is installed in a trapezoidal shape on each ridge, etc. to stabilize ridge tiles or corner tiles installed on the main wing, corner ridge, etc. of the building roof, and to protect it from rainwater etc. These roof tiles and corner tiles are placed. Conventionally, these roof soils were mixed with clay, etc., cut into appropriate sizes on clay soil at the construction site, kneaded with water, applied to each ridge, dried and plastered on the surface. To protect the building from rainwater infiltration. However, according to this method, the work and the construction period are required twice for the installation of the roof soil and the plaster finishing after a certain drying period, and the construction efficiency is inferior. On the other hand, in recent years, there has been proposed a roof soil in which a kneading material obtained by kneading raw materials such as lime, sand, clay, hemp and the like at a predetermined ratio in water is packed in a packaging bag (for example, Japanese Patent Publication No. 5-63426). It has been used since it can be stored for about 50 days in a bag-packed state and does not require plaster surface finishing after construction. However, the roof soil according to the second method also has a viscosity component containing moisture, and when the roof soil dries after construction on site, the clay shrinks due to evaporation of the moisture in the clay, and cracks are formed from the surface to the inside. The cracks cause rainwater to infiltrate through the cracks, and the watertightness is low, and the roof soil gradually weathers and the main building, corner building, or valley of the roof surface leaks and the service life is likely to be shortened. there were.
[0003]
[Problems to be solved by the invention]
On the other hand, in Japanese Patent Application Laid-Open No. Hei 9-140149, the applicant disclosed that the roof soil can be used for a long time in a bag-filled state without using clay, and the work on site can be simplified, and cracks due to drying hardly occur even after construction. Was suggested earlier. However, in the roof soil disclosed in Japanese Patent Application Laid-Open No. 9-110049, it is necessary to add water to the material, knead the material, and pressurize the material with a roller or the like after a required time to adjust the hardness. And a pressurizing step itself is required besides kneading and bagging of the raw materials, which requires a long working time, which is liable to increase the working cost and the product cost. Also, when using slaked lime as a material, even if the bag is packed in a sealed state after pressurization, it hardens over time due to the reaction with carbon dioxide, and when the bag is broken and taken out at the time of use at the work site, Even when the bag is turned over and adhered to the inner surface of the bag, the bag is difficult to be discharged from the bag even when the bag is turned over.
[0004]
The present invention has been made in view of the above-mentioned conventional problems, and one object of the present invention is to produce a crack in soil after construction without the need for a pressurizing step, and to achieve a low cost with a simple configuration. Another object of the present invention is to provide an architectural soil composition and a method for producing architectural soil which can achieve high material, construction cost, easy removal of soil when used on site, and which can maintain good adhesiveness with structural materials. . Another object of the present invention is to provide a building soil composition and a method of manufacturing a building soil that can dramatically increase the shelf life that can withstand use after commercialization.
[Patent Document 1] Japanese Patent Publication No. Hei 5-63426 [Patent Document 2] Japanese Patent Application Laid-Open No. Hei 9-100149
[Means for Solving the Problems]
In order to achieve the above object, the present invention includes quicklime, water having a weight greater than at least quicklime, cut wastepaper obtained by cutting wastepaper into an appropriate size, and aggregate, and kneading these. It is composed of an architectural soil composition sealed and stored in a non-breathable bag after quenching. In addition, an appropriate amount of a binder such as a water repellent material or glass fiber may be mixed. Further, a pigment for producing a blackish color may be appropriately mixed in accordance with the structural material at the time of construction.
[0006]
In addition, the present invention provides a weight ratio of quicklime to aggregate of 0 to 5.5, waste paper of 0.1 to 1, water of 1.75 to 10, an appropriate amount of a water-repellent material, and a binder. , Are quenched, quenched, and hermetically sealed in an air-impermeable bag. The amount of aggregate and the amount of water are changed in order to apply concretely to building soil, for example, for roof tops or painted walls, and to adjust hardness. As the aggregate, sand and calcium carbonate for white coloration and smooth surface finishing may be used. The used paper has at most the same level of quicklime (weight). If too much, the hardened bond between quicklime and aggregate may be rather hindered. Water is different from slaked lime in consideration of the digestive exothermic reaction with quick lime and the amount of water absorbed into waste paper, and is preferably at least 1.75 in weight ratio to the amount of quick lime. In addition, it is preferable that the amount does not exceed 10 times (weight ratio) the amount of quicklime even in consideration of time-dependent factors such as storage, shipping, on-site use, etc. in a non-breathable bag.
[0007]
Further, the present invention, the quick lime, at least water with a weight greater than the quick lime, cut waste paper obtained by cutting waste paper into an appropriate size, aggregate, water repellent material, and binder, after stirring and kneading, It consists of a method of manufacturing architectural soil which is quenched, packed in non-breathable bags and sealed.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the construction soil composition of the present invention, including a method for producing the same, will be described with reference to the drawings. The architectural soil composition of the present invention is a composition applied as architectural soil as a base material for a roof portion or a wall of a building.
[0009]
The architectural soil composition of the present invention comprises quicklime, at least water weighing more than quicklime, cut wastepaper obtained by cutting wastepaper into an appropriate size, and aggregate, and after kneading and quenching the mixture, It is configured to be sealed and stored in a breathable bag. Quick lime (CaO) is obtained by firing crushed limestone (CaCo3) in a firing kiln at, for example, about 1000 ° C. or higher, and thermally decomposing it into powder.
[0010]
As the content composition of the composition for building soil, the composition shown in Table 1 below is preferable.
[Table 1]

[0011]
In the embodiment, the architectural soil using the architectural soil composition, quicklime, water at least greater than quicklime, and cut wastepaper obtained by cutting wastepaper into an appropriate size, aggregate, and water-repellent material, After kneading with a binder, the mixture is rapidly cooled, packed in a non-breathable bag, and sealed. FIG. 1 shows a manufacturing process of building soil as one embodiment of the present invention, in which quick lime, calcium carbonate as aggregate, waste paper and water are put into a mixer and stirred and kneaded for about 5 minutes, and thereafter, Then, it is conveyed in a water jacket, rapidly cooled, packed in a non-permeable bag made of synthetic resin or the like, and sealed.
[0012]
Used paper is crushed daily by newspaper crushers, magazines, leaflets, waste paper, and other paper products discharged from various offices, offices, distributors, households, etc. using a crusher to an appropriate size of about 1 cm x 1 cm. The size itself after crushing may be larger or smaller, and is not limited. It may be cut to the same size by a cutting machine. Recovered paper has water absorption and water retention properties, contains various adhesives or adhesive functional substances when commercialized as paper, and contains pulp fibers. Therefore, when used paper is stirred and kneaded with quick lime and other aggregates under water, due to the action of digestion of quick lime, heat is generated to, for example, about 100 ° C. or more. Infiltration into the composition, and evenly distributed and present in the composition, the adhesive itself and the pulp fiber component, when applied as a material for roof soil or painted walls, may cause a deterioration in the bonding properties of itself. Excellent, not to crack.
[0013]
The aggregate may be generally used sand, calcium carbonate (CaCo3) powder, or a mixture thereof. Calcium carbonate powder is obtained by pulverizing limestone, is hardly soluble in water, and can be used as a painted wall material to provide a smooth finished surface and form a fine finished surface. When sand is mainly used as the aggregate, it can be suitably applied as roof soil.
[0014]
As for the water, at least a weight of water which is greater than quick lime is added. Therefore, even if the amount of the aggregate to be charged is taken into consideration, it is formed with the viscosity and the flow degree of the freshly-made rice cake. In this case, it is preferable that water is about 1.75 to 10 with respect to quicklime 1 in weight ratio as in the embodiment. As described above, for example, compared with slaked lime (Ca (OH) 2), a larger amount of water is added because the waste paper absorbs and retains a considerable amount of water, and the quick lime is digested. This is to complete the digestion simply by packing the bag in a non-breathable bag. Generally, fire extinguishing equipment using a screw conveyor and the like and a curing time after digestion are required to produce slaked lime, and if it is obtained at the distribution stage as slaked lime by itself, reflecting its equipment and work costs, it is about twice as fast as quick lime. Costs. Therefore, the production cost can be reduced by kneading the raw lime directly with other aggregates and waste paper together with water, and at the same time, the water absorption and water retention of the waste paper and the strength, adhesion and workability of the generated soil can be improved. Improvement can be achieved.
[0015]
When building soil is used as roofing soil, the cost can be reduced by using a large amount of sand as an aggregate and reducing the amount of calcium carbonate that also maintains whiteness and smoothness. In the case of a black earth color, an appropriate pigment may be used. Further, a water-repellent material for waterproofing (for example, trade name, Rublins) or a binder such as glass fiber may be mixed for reinforcing the strength of the soil. On the other hand, when building soil is used as a painted wall, the amount of calcium carbonate may be increased without using sand in order to maintain the smoothness of the surface during construction.
[0016]
The architectural soil composition includes quicklime, water having a weight greater than at least quicklime, waste paper obtained by cutting wastepaper into an appropriate size, and aggregate, and a kneaded, quenched, non-permeable bag. In addition to the above-mentioned functions, it is possible to prevent the hardening of the building soil packed into a bag for a long period of time by using the water retention property of the waste paper, and to prolong the product life. . In addition, even when stored in a sealed state for about one year, for example, the soil does not adhere to the inner surface of the synthetic resin bag due to the presence of the waste paper. Therefore, when the soil is used at a construction site, the bag is easily turned over. The soil of the contents is discharged to improve workability.
[0017]
【Example】
Hereinafter, examples of the construction soil composition and the method for producing the construction soil of the present invention will be described.
Example 1 Architectural soil for roofing soil was manufactured by the same method and the same process as in the embodiment with the component configuration shown in Table 2 below.
[Table 2]

Example 2 Architectural soil for roof soil was manufactured by the same method and the same process as in the embodiment with the component configuration shown in Table 3 below.
[Table 3]

[Example 3] Architectural soil for a painted wall was manufactured by the same method and the same process as in the embodiment with the component constitutions in Table 4 below.
[Table 4]

Example 4 Architectural soil for a painted wall was manufactured by the same method and the same process as those of the embodiment with the component configuration shown in Table 5 below.
[Table 5]

It was confirmed that the building soil produced as described above did not extremely harden in the contents even if it was stored in a warehouse for about one year, and was sufficiently usable.
[0018]
【The invention's effect】
As described above, according to the building soil composition or the method for manufacturing a building soil according to the present invention, (a) cracks are not generated in the soil after construction without requiring a pressurizing step, and quick lime is not generated. The production cost can be reduced because of using. (B) Flexibility can be maintained for a long time due to the water absorption and water retention of the waste paper, and the product life can be drastically extended. (C) The fiber component of the waste paper is widely distributed inside the soil, and the strength of the product as the soil can be improved. (D) Due to the heat of the quick lime and the water, the waste paper component elements melt out during the kneading and disperse widely in the soil, and as a result, the waste paper component is removed via the adhesive contained in the waste paper or the adhesive functional material. Adhesion with the structural material can be improved. (E) The soil does not adhere to the inner surface of the synthetic resin bag due to the presence of the waste paper. Therefore, if the bag is inverted when the soil is used at the construction site, the soil of the contents is easily discharged, and the workability is improved. Can be improved.
