Description
本発明は、コンクリートの養生、特に養生コンクリートの表面に張り付けて養生するコンクリートの養生シートとその製造方法に関する。 The present invention relates to a concrete curing sheet, in particular, a concrete curing sheet that is stuck to the surface of a curing concrete and cured, and a method for manufacturing the same.
現在用いられている養生方法として、水平面の湿潤養生と鉛直面の湿潤養生がある。 Currently used curing methods include a horizontal wet surface and a vertical wet surface.
まず、水平面の湿潤養生には、養生するコンクリート面に直接散水する直接散水法と、養生コンクリートの周囲に型枠を設置し、その中に水を溜めて実施する湛水による給水養生法がある。しかし、これらの養生法は、水の蒸発を防ぐことができないために、散水が不経済であり、また水を溜める堰を設けて適量の水を補給しなければならないという問題がある。 First, there are two types of wet curing: horizontal water spraying, which directly sprinkles on the concrete surface to be cured, and water supply curing, which is performed by installing a formwork around the concrete and storing water in it. . However, these curing methods cannot prevent evaporation of water, so that watering is uneconomical, and there is a problem that a proper amount of water must be supplied by providing a weir for storing water.
そのために、１〜２ｃｍ厚程度の不織布で水を保水する給水マットを用いる方法もあるが、マット表面からの水の蒸発を防ぐことができず、適宜水の補給が必要であり、またマットに水が含まれて重量が大きくなり、移動と施工時の敷き均し工事が不便であり、これを解決するためには一度乾燥させて重量を軽減させてから運搬・施工していた。 Therefore, there is a method using a water supply mat that retains water with a non-woven fabric having a thickness of about 1 to 2 cm. However, evaporation of water from the surface of the mat cannot be prevented, and water needs to be replenished appropriately. It contains water, increases in weight, and is inconvenient for moving and laying the floor during construction. To solve this, it was transported and constructed after it was dried once to reduce the weight.
さらに、ビニールシートでコンクリート表面を覆って水の蒸発を防ぐ封かん養生法があるが、シートそのものに保水性能がないために、常に給水を行なう必要があり、またシート自体が軽量であるために乾燥すると風により養生コンクリート表面からシート剥離が生じるという不都合があった。 In addition, there is a sealing curing method that covers the concrete surface with a vinyl sheet to prevent water evaporation, but since the sheet itself does not have water retention performance, it is necessary to always supply water, and because the sheet itself is lightweight, it is dry Then, there was an inconvenience that the sheet peeled off from the surface of the hardened concrete by the wind.
一方、鉛直面の湿潤養生として、型枠内にコンクリートを打設して養生する型枠養生法がある。しかし、型枠内にコンクリートを打設した後では給水ができないため、予め余分の水を含ませておく必要があり、また型枠を養生中残置するために、養生時間が掛かり、その間型枠も他に転用できず、数多くの在庫が必要であった。 On the other hand, there is a mold curing method in which concrete is placed and cured in a mold as a vertical wet curing. However, since water cannot be supplied after placing concrete in the formwork, it is necessary to add extra water in advance, and it takes time for curing to leave the formwork during curing. Could not be diverted to others, and a lot of stock was needed.
また、型枠を早く脱型してから養生コンクリートの表面にビニールシート等を掛けて水の蒸発を防ぐ封かん養生法も施工されているが、シートそのものに保水性能がなく、軽量のために風等により剥離し易いという欠点がある。 In addition, a sealing curing method that prevents the evaporation of water by placing a vinyl sheet etc. on the surface of the curing concrete after the mold has been removed early has been implemented. There is a drawback that it is easy to peel off.
さらに、本出願人による下記の先行文献として、コンクリート面にメッシュの浸水物を添付した不透水シートを、負圧によりコンクリートに密着させて保水物に水を添加させる給水養生装置とその方法がある。ただ、これは運搬が容易で、養生も優れたものであるものの、コンクリート面に添付した浸水物に給水し、吸引する装置を設置するために設備費用と、設置に時間と手間が掛かるという問題点があった。 Further, as the following prior literature by the present applicant, there is a water supply curing apparatus and method for adding water to a water retaining material by adhering a water-impermeable sheet with a mesh submerged material attached to the concrete surface by negative pressure to the concrete. . However, although this is easy to transport and excellent in curing, there is a problem that it takes equipment cost and time and labor to install the device that supplies and sucks the inundated material attached to the concrete surface. There was a point.
本発明は、前記問題点を解決せんとするもので、簡易な構造によるも、以下の性能を全て満足させるコンクリートの養生シートとその製造方法を提供するものである。
ａ)保水性：シートが養生水を給水して保水できる性能がある。
ｂ）乾燥防止性：コンクリート表面や養生水の蒸発を防ぎ、乾燥を防止する性能がある。
ｃ）形状追随性：ハンチや開口部、箱抜き等の対象構造物の細かな形状への追随性もある。また、養生中の面において、足場等の仮設物を設置する時に、シートと足場間を隙間なく養生することができる性能も存する。
ｄ）耐久性：繰返し転用する耐久性もある。
ｅ）移動性：養生中のシートを他の場所に移動する時の移動の便利性もある。
ｆ）施工性：施工時に養生シートを容易に設置できる。
ｇ）効果の確実性：従来の養生方法では、コンクリート面の乾燥、シートの剥離、シート設置時にできる隙間等の不都合が生じることが考えられ、養生の効果が確実に担保できない場合があるが、本発明はこのような欠点も存在しない。
The present invention is intended to solve the above-mentioned problems, and provides a concrete curing sheet that satisfies all of the following performances and a method for producing the same, even with a simple structure.
a) Water retention: The sheet has a performance capable of retaining and retaining the curing water.
b) Drying prevention property: It has a performance to prevent the concrete surface and curing water from evaporating and drying.
c) Shape followability: There is also followability to a fine shape of a target structure such as a haunch, an opening, or a box. In addition, in terms of curing, there is also a performance that allows the sheet and the scaffold to be cured without a gap when a temporary object such as a scaffold is installed.
d) Durability: Durability of repeated use.
e) Mobility: There is also the convenience of movement when the sheet being cured is moved to another location.
f) Workability: A curing sheet can be easily installed during construction.
g) Certainty of the effect: In the conventional curing method, there may be inconveniences such as drying of the concrete surface, peeling of the sheet, gaps created at the time of sheet setting, etc., and the curing effect may not be guaranteed reliably. The present invention does not have such a drawback.

Bonded, the plastic resin non-woven fabric is a sheet of polyethylene terephthalate, polypropylene, or nylon, or a joining sheet thereof, and the impervious plastic sheet is a sheet of polyethylene, polypropylene, or polybutadiene terephthalate, or these This joining sheet is inexpensive, has strength, and is preferable for handling.
つぎに、請求項４の発明は、前記請求項１又は２のいずれかにおいて、プラスチック製の不織布シートが２０ｇ／ｍ2〜１００ｇ／ｍ2の範囲で、その片面に２０μｍ〜７０μｍの不透水性のプラスチックシートを接合したもので、これらにより薄膜で取り扱いが簡単な養生シートを得ることができる。なお、前記不織布シートが２０ｇ／ｍ2未満であるとコンクリートの養生時の給水が不織布シートに万遍なく行き渡らないか、行き渡りに時間が掛かり、１００ｇ／ｍ2超であると、本発明の養生シートがコンクリート面から離脱する虞がある。また、不透水性のプラスチックシート２０μｍ未満であれば、そのシートに穴が開き、７０μｍ超の場合にはコスト高で、養生コンクリート面への貼り付けも十分でなくなる。 Next, the invention of claim 4, in any one of the claims 1 or 2, in the range plastic nonwoven sheet is 20 g / m 2 to 100 g / m 2, impermeable 20μm~70μm on one side The plastic sheet is joined and a cured sheet that is easy to handle with a thin film can be obtained. In addition, when the nonwoven fabric sheet is less than 20 g / m 2 , the water supply during curing of the concrete does not spread evenly over the nonwoven fabric sheet, or it takes time to spread, and if it exceeds 100 g / m 2 , the curing of the present invention There is a possibility that the sheet may come off from the concrete surface. If the water-impermeable plastic sheet is less than 20 μm, a hole is formed in the sheet.
さらに、請求項５の発明は、前記請求項１乃至３のいずれかにおいて、コンクリート養生シートの一端部には、水道栓等の給水手段からの水を不透水性のプラスチックシートと養生するコンクリート間に、散水できるようにした多数孔を有する散水ホースを配置して、養生シートの全面に最適な給水を施すことができる。 Further, the invention according to claim 5 is the method according to any one of claims 1 to 3, wherein the concrete curing sheet is provided with an impervious plastic sheet for curing water from water supply means such as a water tap at one end of the concrete curing sheet. In addition, a watering hose having a large number of holes so that water can be sprayed can be arranged to provide optimum water supply to the entire surface of the curing sheet.
そして、本発明の請求項６は、このようにしてロールに巻き取られた親水化剤を混入したプラスチック製の不織布を、冷却ロールとニップロール間に送出し、これに前記各ロール間で前記プラスチック製の不織布と相溶性のある溶融状態のプラスチック樹脂をシート状にした不透水性のプラスチック製のシートと溶着して送り出して接合といった、比較的簡素な設備で多量にコンクリートの養生シートを仕上げることができるようにしたものである。
なお、請求項７として、前記親水性を有するプラスチック製の不織布と不透水性のプラスチック製のシートとの接合が、前記溶着に代えて、接着剤により接合することもできる。
According to a sixth aspect of the present invention, a plastic non-woven fabric mixed with the hydrophilizing agent wound around the roll in this way is fed between the cooling roll and the nip roll, and the plastic is transferred between the rolls. Finishing a large amount of concrete curing sheet with relatively simple equipment such as welding and sending and joining to a water-impermeable plastic sheet made of a melted plastic resin compatible with a non-woven fabric It is made to be able to.
In addition, as a seventh aspect, the bonding between the hydrophilic plastic nonwoven fabric and the water-impermeable plastic sheet can be bonded by an adhesive instead of the welding.
本発明のコンクリート養生シートを使用するには、養生するコンクリートと不透水性のプラスチック製シート間にあるプラスチック樹脂製の不織布に水を供給して行きわたらせ、ゴム製の水切り具等でコンクリート面の養生シート上を一方から他方に沿って押圧していくと、前記不織布内に存在する空気が養生シートの外部に押し出されることで、前記不透水層とコンクリート面間を表面張力によって張着して不透水層とコンクリート間で不織布中の保水性が保たれ、簡単で効率的にコンクリートの養生が図れる。 In order to use the concrete curing sheet of the present invention, water is supplied to the non-woven fabric made of plastic resin between the curing concrete and the impermeable plastic sheet, and the concrete surface is removed with a rubber drainer or the like. When pressing on the curing sheet from one side to the other, the air present in the nonwoven fabric is pushed out of the curing sheet, so that the impermeable layer and the concrete surface are stuck by surface tension. The water retention in the nonwoven fabric is maintained between the impermeable layer and the concrete, and the curing of the concrete can be performed easily and efficiently.
また、不織布の凹凸が、コンクリート表面における微細な凹凸にも対応でき、水による養生シートの密着性が良い。 Moreover, the unevenness | corrugation of a nonwoven fabric can respond also to the fine unevenness | corrugation in the concrete surface, and the adhesiveness of the curing sheet by water is good.
本発明者らは、本発明と従来品とを比較したものを、表１のコンクリート水平面への適用性と、表２のコンクリートの鉛直面への適用性とに分けて実験した。その結果によると、本発明は従来技術に較べて、表に示す性能と歩掛りのあらゆる項目について、全て良好な結果が得られた。 The inventors conducted an experiment comparing the present invention with a conventional product, divided into the applicability to the concrete horizontal surface in Table 1 and the applicability to the vertical surface of the concrete in Table 2. According to the results, the present invention has obtained favorable results for all items of performance and yield shown in the table as compared with the prior art.
上記表１と２によれば、養生コンクリートの水平面も鉛直面も簡易な方法で給水養生ができ、型枠の早期脱型が要求される工程の厳しい現場でも、工程に悪影響を与えることなく、養生コンクリートの良好な品質が確保できる。 According to the above Tables 1 and 2, the horizontal and vertical surfaces of the cured concrete can be water-cured by a simple method, and even in harsh sites where the early demolding of the mold is required, the process is not adversely affected. Good quality of hardened concrete can be secured.
本発明のコンクリート養生シートを、養生コンクリート上に掛け、別途用意した給水装置から不透水性のプラスチック製シートとコンクリート面間の、プラスチック製の不織布に水を供給し、不透水性のプラスチック製シート上からゴム製の水切り具を養生コンクリートの中央から周辺に移動するだけで、不織布中にある空気を粗方脱気することができ、養生シートは水の表面張力により養生コンクリート面上に貼り付けられ、工事に必要な人員や設備が省ける。 The concrete curing sheet of the present invention is hung on the curing concrete, water is supplied from a separately prepared water supply device to the non-woven fabric made of plastic between the impermeable plastic sheet and the concrete surface, and the impermeable plastic sheet By simply moving a rubber drainer from the center to the periphery of the curing concrete, the air in the nonwoven fabric can be roughly degassed, and the curing sheet is affixed to the curing concrete surface by the surface tension of the water. This saves the personnel and equipment necessary for the construction.
本発明の養生シートは、比較的薄いために、通常紙に使用するはさみやカッターにより養生面に合わせた形状に切断することで、現場に合わせて隙間無く養生シートを貼り付けることができる。 Since the curing sheet of the present invention is relatively thin, the curing sheet can be pasted without gaps in accordance with the site by cutting into a shape that matches the curing surface with scissors or a cutter used for normal paper.
本発明のコンクリート養生シートは、親水性を有するプラスチック樹脂製の不織布と、その片面に不透水性のプラスチック製シートを接合したコンクリート養生シートと、そのコンクリート養生シートに多数孔を有する散水ホースを取り付けたもの、及びその製造方法を提供する。 The concrete curing sheet of the present invention includes a non-woven fabric made of plastic resin having hydrophilicity, a concrete curing sheet in which an impermeable plastic sheet is bonded on one side, and a watering hose having a plurality of holes in the concrete curing sheet. And a manufacturing method thereof.
図１は、本発明である養生シートＡ、すなわち親水化剤としてグリセリンを混入したＰＥＴとＰＰを積層した５０ｇ／ｍ2のプラスチック樹脂製の不織布シート２に３０μｍのＰＥである不透水性のプラスチック製シート３を重ねたものを養生コンクリート１の表面に添加し、その上で前記プラスチック樹脂製の不織布シート２中に養生水４を入れ貼り合せて接合物にしたものである。
ここで、前記プラスチック樹脂製の不織布２は、各メーカーの周知技術を用いることができるが、中でも前工程としてバーストファイバー法とトウ開繊法の組み合せによる積層延展法を用いた不織布（ユニセルＫＫ製）を採用した。なお、この他に水流結合法（スパンレース法）、スパンボンド法、ケミカルボンド法、サーマルボンド法、又はニードルパンチ法を用いて不織布を製造することもできる。
FIG. 1 shows a curing sheet A according to the present invention, that is, a non-permeable plastic that is 30 μm PE on a non-woven sheet 2 made of 50 g / m 2 plastic resin in which PET and PP mixed with glycerin as a hydrophilizing agent are laminated. A laminate of the sheet 3 is added to the surface of the curing concrete 1, and then the curing water 4 is put into the nonwoven fabric sheet 2 made of the plastic resin and bonded to form a bonded product.
Here, the plastic resin nonwoven fabric 2 can use a well-known technique of each manufacturer, but among them, a nonwoven fabric (manufactured by Unicel KK) using a laminate spread method by a combination of a burst fiber method and a tow opening method as a pre-process. )It was adopted. In addition, a nonwoven fabric can also be produced using a water flow bonding method (spun lace method), a spun bond method, a chemical bond method, a thermal bond method, or a needle punch method.
また、上記したように、本発明のコンクリート養生シートＡには、養生コンクリート１に貼り合わせて不織布シート２中に水を散布して貼合するが（図１）、この場合、図２に示すように、コンクリート養生シートＡにおける不織布シート２側の一端部から少し置いた距離５を取って、散水するための多数孔７を一定間隔に設けた散水ホース６を配線ステッカーと粘着テープ（図示せず）で添着しておき、給水装置（図示せず）からの養生水を散水ホース６を通して多数孔７から不織布２内へ万遍なく散布することにより、コンクリートを養生する。 As described above, the concrete curing sheet A of the present invention is bonded to the curing concrete 1 and sprayed and bonded to the nonwoven fabric sheet 2 (FIG. 1). In this case, as shown in FIG. Thus, the water spraying hose 6 which provided the multiple hole 7 for watering at a certain distance from the one end part by the side of the nonwoven fabric sheet 2 in the concrete curing sheet A was provided with the wiring sticker and the adhesive tape (not shown) The concrete is cured by spraying the curing water from the water supply device (not shown) through the sprinkling hose 6 and into the nonwoven fabric 2 evenly.
つぎに、本発明のコンクリート養生シートＡを製造する方法を図４により説明する。
ロール状に巻き取られた親水化剤を混入したＰＥＴとＰＰを積層した不織布２を引き出し、冷却ロール８と、これと間隙を調整することができるニップロール９間に送る。この工程と同時に、容器に入れた溶融したＰＥ樹脂を不透水性のシートとし、前記した冷却ロール８とニップロール９間にあるＰＥの不織布２の片面に溶着した層状にラミネートし、これらを本発明の製品１０として巻き取る。
Next, a method for producing the concrete curing sheet A of the present invention will be described with reference to FIG.
The nonwoven fabric 2 laminated with PET and PP mixed with a hydrophilizing agent wound in a roll shape is pulled out and sent between the cooling roll 8 and the nip roll 9 which can adjust the gap. Simultaneously with this step, the melted PE resin contained in a container is made into a water-impermeable sheet, and laminated in a layer form that is welded to one side of the PE nonwoven fabric 2 between the cooling roll 8 and the nip roll 9, and these are laminated in the present invention. The product 10 is wound up.
このようにして出来た本発明のコンクリート養生シートＡをコンクリートの養生に用いるには、図３に示すように、コンクリート１の養生面に、プラスチック製の不織布シート２側を付着し、散水ホース６に水を供給して、コンクリート１と不透水のプラスチックシート３間の不織布シート２内に養生水を行き渡らせ、別途用意したゴム製の水切り具３０を用いて不織布シート２内に残在する空気をシート外に排出することで、コンクリート養生シートＡを十分にコンクリート１面に貼着することができる。
なお、散水ホース６からの給水は、コンクリートの容積やコンクリート製造時における急結剤の投入等に応じた多数孔７の口径と間隔配分により、所要時間を区切った間欠散水をすることができる。
In order to use the concrete curing sheet A of the present invention thus produced for curing concrete, as shown in FIG. 3, the plastic nonwoven fabric sheet 2 side is attached to the curing surface of the concrete 1, and the watering hose 6. Water is supplied to the nonwoven fabric sheet 2 between the concrete 1 and the impervious plastic sheet 3 and air remaining in the nonwoven fabric sheet 2 using a rubber drainer 30 separately prepared. Is discharged out of the sheet, the concrete curing sheet A can be sufficiently adhered to one surface of the concrete.
The water supply from the sprinkling hose 6 can be intermittently sprinkled by dividing the required time by the diameter and interval distribution of the multi-holes 7 according to the volume of the concrete and the introduction of the quick setting agent during the concrete production.
本発明のコンクリート養生シートは、コンクリートの養生に用いられることになるが、その場合にもコンクリートの水平面はもちろん垂直面等の傾斜面においても十分に貼り付けられ、水を供給することで、コンクリート面に十分に貼りつけて使用することができる。 The concrete curing sheet of the present invention will be used for curing concrete, but in that case, the concrete curing sheet is sufficiently pasted not only on a concrete horizontal surface but also on an inclined surface such as a vertical surface, and by supplying water, It can be used by sticking to the surface.
