Description

【0001】
【発明の属する技術分野】
本発明は床シートの巻取り構造において、床シートの巻芯部に位置する床シート端部に起因する巻き段を効果的に防止可能な床シートの巻取り構造に関する。
【0002】
【従来の技術】
従来、長尺床シートは紙管等の芯材に巻き取られて保管され、施工の際、巻き取られた床シートを現場で広げ養生させることにより、巻き取りによって生じた巻芯部に位置する床シート端部の段差に起因する巻跡、いわゆる巻き段を矯正してから下地に糊付けし、前記床シートを施工することが一般的に行われている。しかしながら、床シート自体が柔らかい場合、床シートの巻き段が特につき易いが、床シートは施工性面等の要請から、比較的柔らかいものが多い。一般に巻跡は床に敷設する際、上述した養生によっても、完全に矯正することは不可能である。また、前記巻き段は床シートに内在する大きな問題であり、改善が強く望まれていた。そこで、紙管の吸湿防止も兼ねて、紙管に非透湿フィルムを5〜6周巻き付け、その巻終わり側端部にプリプレグの巻き始め側端部を挟み込んで巻き取りを開始する旨の技術が開示されている(例えば、特許文献1参照。)。また、円筒形の芯材の表面にシート厚さ分と同じ緩和部からなる凹部を設ける旨の技術が開示されている(例えば、特許文献2参照。)。

【特許文献2】
特開平11−263537号公報(第2頁)
【0004】
【発明が解決しようとする課題】
しかしながら、前者の技術は巻終わり側端部にプリプレグの巻き始め側端部を挟み込んで巻き取らなければならないため、巻き取り工程が煩雑であり労力面で負担が大きい。また、設備面でも特殊な設備を必要するため、設備投資を要すること、及び床シート等を巻き取る紙管や梱包に要することから、経済面でも従来の梱包形態と比較して、遥かに不利である。
【0005】
また、後者の技術は芯材に切り込み部を設けるという特殊な加工が必要であり、巻き取り対象のシートの端部を前記切り込み部に合わせて巻き取らなければ、床シート等の段差に起因するエンドマーク防止効果を十分に奏することはできない。前記芯材の切り込み部に床シート等の端部を合わせて巻き取ることは工程上、煩雑であり、現実には作業者が手作業で前記作業を行うか、或いは特殊な設備を導入して前記作業を行うかしなければならず、何れにしても、作業面での負担、若しくは設備導入等による経済面での負担は避けられない。
【0006】
【課題を解決するための手段】
そこで、本発明は上記問題を解決したものであり、請求項1記載の発明は円筒状の芯材に床シートが巻き取られた巻き物の構造において、前記床シートの巻芯に位置する端部を表面から、柔軟性シートにより覆ったことを特徴とする床シートの巻取り構造を、請求項2記載の発明は請求項1記載の発明の特徴に加えて、柔軟性シートが構造を有した紙、又は合成樹脂からなる発泡体であることを特徴とする床シートの巻取り構造を、請求項3記載の発明は請求項2記載の発明の特徴に加えて、合成樹脂発泡体の発泡倍率が10〜40倍あることを特徴とする床シートの巻取り構造を、請求項4記載の発明は請求項2、又は3記載の発明の特徴に加えて、合成樹脂がポリエチレン樹脂、又はウレタン樹脂の何れか一方である請求項2又は3記載の床シートの巻取り構造を、請求項5記載の発明は請求項2〜3記載の発明は請求項2〜4記載の発明の何れか一の特徴に加えて、合成樹脂発泡体の厚みが1.5〜5mmである請求項2〜4の何れか一に記載の床シートの巻取り構造、をその要旨とする。
【0007】
【発明の実施の形態】
以下、図面を参照しながら、本発明床シートのエンドマーク防止構造についてさらに詳述する。
図1は本発明床シートの巻き取り構造の一例の側面図を示す。また、図2は本発明床シートの巻き取り構造を構成する柔軟性シートの一例の斜視図を示す。図1に示すように、床シートの芯側に位置する端部5(以下、床シート芯側端部と記す)が芯材3に位置する部分を覆うような状態で柔軟性シート2が設けられている。柔軟性シート2は少なくとも床シート芯側端部5を覆う大きさがあればよく、幅は床シートの幅±200mm、長さは床シートの幅に拘わらず、50〜300mmが好ましい。ここで、柔軟性シートの幅とは芯材の長さ方向の大きさをいい、柔軟性シートの長さとは床シートの巻き取り方向の大きさをいう。柔軟性シート2の幅が上記幅より小さい場合は、床シートの巻物の双方、若しくは一方の端部で巻ぐせが起こることがあり、逆に大きすぎる場合には、床シートの巻物の端部から柔軟性シート2が飛び出し、包装紙での円滑な梱包作業が柔軟性シートにより、妨げられたり、梱包後の床シートの保管、運搬に支障をきたすことがある。また、柔軟性シートの長さが上記長さより小さい場合には床シート芯側端部を覆うことが困難となり、作業性面より好ましくなく、逆に大きすぎる場合には床シートの巻物の大きさが大きくなり、前記巻物が取り扱いにくくなったり、或いは巻物自体を包装するための包装紙が必要以上に多く要し、経済面でも問題がある。さらに、施工現場においても廃棄物が多くなる等環境面からも好ましくない。
【0008】
また、柔軟性シートの材質としては、シート状であって、柔軟性のある素材から形成されていれば任意の素材を使用することができるが、弾性を持った柔軟性シートが好ましい。前記弾性を持った柔軟性シートを形成する素材としては、合成樹脂、より具体的にはウレタン樹脂、ポリエチレン樹脂が挙げられる。柔軟性シートの素材として、合成樹脂を使用する場合は、発泡させることがより好ましい。発泡させることにより、柔軟性が増し、弾力性が付与されるため、エンドマークを防止する効果が発泡させない場合より、遥かに大きくなる。発泡倍率は10〜40倍が好ましく、20倍〜35倍がより好ましい。
【0009】
さらに、柔軟性シートの厚みについては1.5〜5mmが好適である。前記厚みが1.5mm未満になると巻きぐせを防止する効果が不足するという問題が生じることがあり、一方5mmを超えると逆に柔軟性シートによる巻きぐせがついてしまうという点で好ましくない。
【0010】
【発明の効果】
本発明は上記のように実施され、下記の効果を奏する。
ウレタン樹脂、ポリエチレン樹脂等の合成樹脂発泡体等である柔軟性シートにより、床シート芯側端部を覆うことにより、特別な設備、及び煩雑な作業なく前記床シート芯側端部に起因する床シートの巻き段を効果的に防止することができる。また、柔軟性シートは上述したように、ウレタン樹脂、ポリエチレン樹脂等の合成樹脂発泡体であるため、本発明構造体自体もさほどコストアップすることなく、また、発生する廃棄物も最小限に抑えつつ、床シートの巻き段を防止することができる。

TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor sheet winding structure capable of effectively preventing a winding step caused by a floor sheet end located at a core portion of a floor sheet in a floor sheet winding structure.
[0002]
[Prior art]
Conventionally, a long floor sheet is wound and stored on a core material such as a paper tube. During construction, the wound floor sheet is spread and cured at the site, and is positioned at a core portion generated by winding. It is a common practice to correct the winding marks caused by the step at the end of the floor sheet, that is, the so-called winding step, and then glue it to the base to apply the floor sheet. However, when the floor sheet itself is soft, the winding step of the floor sheet is particularly easy to form, but the floor sheet is often relatively soft due to the demand for workability. In general, when laying a wound on a floor, it is impossible to completely correct it even by the above-mentioned curing. Further, the winding step is a major problem inherent in the floor sheet, and improvement has been strongly desired. In order to prevent moisture absorption of the paper tube, a technique of winding a non-moisture permeable film around the paper tube for 5 to 6 turns, and sandwiching the winding start end of the prepreg at the winding end side to start winding. Is disclosed (for example, refer to Patent Document 1). In addition, a technique has been disclosed in which a concave portion composed of a relief portion having the same thickness as the sheet is provided on the surface of a cylindrical core material (for example, see Patent Document 2).

[Patent Document 2]
JP-A-11-263537 (page 2)
[0004]
[Problems to be solved by the invention]
However, in the former technique, since the winding end of the prepreg must be sandwiched between the winding end side and the winding end side, the winding process is complicated and the burden on labor is large. In addition, special equipment is required in terms of equipment, so capital investment is required, and paper tubes and rolls for winding floor sheets etc. are required. It is.
[0005]
In addition, the latter technique requires a special process of providing a cut portion in the core material, and if the end of the sheet to be wound is not wound in accordance with the cut portion, it is caused by a step of a floor sheet or the like. The effect of preventing end marks cannot be sufficiently achieved. It is complicated in the process to wind up the edge of the floor sheet or the like with the cut portion of the core material, and in reality, the worker manually performs the work or introduces special equipment. The work must be performed, and in any case, the burden on the work, or the burden on the economy due to the introduction of equipment and the like is inevitable.
[0006]
[Means for Solving the Problems]
In view of the above, the present invention has solved the above-mentioned problem, and the invention according to claim 1 has an end located at the core of the floor sheet in the structure of a roll in which the floor sheet is wound around a cylindrical core material. The invention described in claim 2 has a structure in which the flexible sheet has a structure in which the flexible sheet has a structure in which the flexible sheet is covered with a flexible sheet from the surface. The winding structure of the floor sheet, which is a foam made of paper or a synthetic resin, is characterized in that the invention according to the third aspect has the expansion ratio of the synthetic resin foam in addition to the features of the second aspect. The present invention according to claim 4 is characterized in that the synthetic resin is a polyethylene resin or a urethane resin in addition to the feature of the invention according to claim 2 or 3. The method according to claim 2 or 3, wherein The winding structure of the floor sheet, the invention according to claim 5, the invention according to claims 2 to 3, in addition to any one of the features according to claims 2 to 4, the thickness of the synthetic resin foam is 1 The gist of the floor sheet winding structure according to any one of claims 2 to 4, which is 0.5 to 5 mm.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the end mark prevention structure of the floor sheet of the present invention will be described in more detail with reference to the drawings.
FIG. 1 shows a side view of an example of the floor sheet winding structure of the present invention. FIG. 2 is a perspective view of an example of the flexible sheet constituting the winding structure of the floor sheet of the present invention. As shown in FIG. 1, the flexible sheet 2 is provided in such a state that an end 5 located on the core side of the floor sheet (hereinafter, referred to as a floor sheet core end) covers a portion located on the core material 3. Have been. The flexible sheet 2 has only to have a size that covers at least the floor sheet core side end 5, and the width is preferably ± 200 mm and the length is preferably 50 to 300 mm regardless of the width of the floor sheet. Here, the width of the flexible sheet refers to the size in the length direction of the core material, and the length of the flexible sheet refers to the size in the winding direction of the floor sheet. If the width of the flexible sheet 2 is smaller than the above-mentioned width, winding may occur at both ends or at one end of the roll of the floor sheet. The flexible sheet 2 may protrude from the sheet, and smooth packing work with the wrapping paper may be hindered by the flexible sheet, or storage and transportation of the floor sheet after packing may be hindered. Also, if the length of the flexible sheet is smaller than the above length, it is difficult to cover the end of the floor sheet at the core side, which is not preferable from the viewpoint of workability. And the scroll becomes difficult to handle, or wrapping paper for wrapping the scroll itself is required more than necessary, which is economically problematic. Furthermore, it is not preferable from the environmental point of view, such as an increase in wastes at the construction site.
[0008]
Further, as the material of the flexible sheet, any material can be used as long as it is sheet-like and formed of a flexible material, but an elastic flexible sheet is preferable. Examples of the material forming the flexible sheet having elasticity include synthetic resins, more specifically, urethane resins and polyethylene resins. When a synthetic resin is used as the material of the flexible sheet, it is more preferable that the flexible sheet be foamed. By foaming, flexibility is increased and elasticity is imparted, so that the effect of preventing end marks is far greater than when foaming is not performed. The expansion ratio is preferably from 10 to 40 times, more preferably from 20 to 35 times.
[0009]
Further, the thickness of the flexible sheet is preferably 1.5 to 5 mm. If the thickness is less than 1.5 mm, there may be a problem that the effect of preventing curling may be insufficient.
[0010]
【The invention's effect】
The present invention is implemented as described above, and has the following effects.
The floor sheet core end is covered with a flexible sheet made of a synthetic resin foam such as urethane resin or polyethylene resin, so that the floor caused by the floor sheet core end can be used without special equipment and complicated work. The step of winding the sheet can be effectively prevented. In addition, as described above, since the flexible sheet is a synthetic resin foam such as urethane resin or polyethylene resin, the structure of the present invention itself does not significantly increase the cost and minimizes waste generated. In addition, the winding steps of the floor sheet can be prevented.
