Description
【０００１】[0001]
本考案は、建物屋上等に敷設される防水シートに関し、更に詳しくは接着剤を 用いて又は用いずに建物屋上面に施設される防水シートに関する。 The present invention relates to a waterproof sheet laid on the roof of a building, and more particularly to a waterproof sheet installed on the upper surface of a building with or without an adhesive.
【０００２】[0002]
従来、屋上等のシート防水工法において、防水シートの側端部同士を重ねて繋 ぎ合わせた後、下地面に接着剤で接着固定するシート防水工法が行われており、 又、接着剤を用いずに防水シートを下地面から浮かして防水施工を行う、いわゆ る絶縁防水工法も行われている。 いずれの方法にしろ、シートの側端部を接合する場合には、シートの側端部に ４０〜５０ｍｍの重ねしろをとり、加熱融着又は溶剤による溶着によって接合し て水密性となし、屋上等の防水すべき下地面全面に接着させて防水処理している 。 特に、接着剤を使用しない絶縁防水工法は接着剤を用いて防水シートを敷設す る方法とは異なり、下地面が濡れていても防水シートを敷設することが出来る、 即ち、天候に左右されずに施工が出来るので、工期が短縮される等の特徴を有す る。この絶縁防水工法は塩化ビニル樹脂等で被覆された固定金具で防水シートを 下地面に機械的に固定するものである。 上記絶縁防水工法により敷設された防水シートは、屋上下地面より浮いている ので、施工時及び施工後に風圧で吹き上げられ易いという点があり、この為それ ぞれの屋上に合った固定金具を防水シートを通して下地面に打ち込み、防水シー トを下地面に固定する。 Conventionally, in the sheet waterproofing method for rooftops, etc., the sheet waterproofing method has been performed in which the side edges of the waterproof sheet are overlapped and joined together, and then adhered and fixed to the base surface with an adhesive. Instead, the waterproof sheet is floated from the base surface for waterproofing, so-called insulation waterproofing method is also used. Whichever method is used, when the side edges of the sheet are to be joined, a 40-50 mm overlap margin is taken on the side edges of the sheet, and the sheets are water-tight by joining them by heat fusion or solvent welding. It is waterproofed by adhering it to the entire surface of the underlying surface to be waterproofed. In particular, the insulation waterproof method that does not use an adhesive can lay a waterproof sheet even if the ground surface is wet, unlike the method of laying a waterproof sheet using an adhesive. Since it can be installed at any time, it has the feature of shortening the construction period. This insulation and waterproof method mechanically fixes the waterproof sheet to the lower ground with a fixing metal fitting covered with vinyl chloride resin or the like. Since the tarpaulin laid by the above-mentioned insulation and waterproof method floats above the ground above and below the roof, it is easy to be blown up by wind pressure during and after construction.For this reason, the fixing brackets suitable for each roof are waterproofed. Drive the sheet through the sheet and fix the waterproof sheet to the surface.
【０００３】[0003]
上記のいずれの防水工法においても、防水シートの側端部に４０〜５０ｍｍの 重ねしろをとり、これを前記の様に接合するが、従来は重ねる幅は目測によって 決めていたので、重ねる幅が斜めになったり、重ねしろが決められた幅より狭く なったりすることがあり、その為施工現場において定規等より幅や長さを測り、 印を付けるという煩雑性があった。これは多大な時間と手間を要し防水施工の工 期の遅れの原因となっている。 又、前記絶縁防水工法においては、風圧は施工場所が高くなるほど高くなり、 敷設された防水シートの屋上外周部分の風圧が中央部分の風圧よりも高いことが 知られている。又、屋上下地面のコンクリートの種類によってもコンクリートの 強度が異なるので、防水シートを固定する為に打ち込む固定具の数が異なってく る。風圧力は一般的に次式で表わされる。 Ｐ＝Ｃ・ｑ ≪Ｐ：風圧力（Ｋｇ／ｍ2 ）、ｑ：速度圧（Ｋｇ／ｍ2 ）、Ｃ：風力係数≫ ｑ＝６０√ｈ・・・・ｈ≦１６ ｑ＝１２０4 √ｈ・・・ｈ＞１６ （ｈ：建物の高さ：ｍ） この計算式を基にして、敷設される防水シートを固定するのに必要な位置と固 定金具の数を決定する。一般的には１ｍ2 当たり１〜２個の固定金具を打ち込み 防水シートを下地面に固定する。In any of the above waterproofing methods, a 40-50 mm overlap margin is taken on the side edge of the waterproof sheet, and this is joined as described above, but in the past, the overlap width was determined by eye measurement, so the overlap width is It may become slanted or the overlap may be narrower than the specified width, so there was the complexity of measuring the width and length with a ruler at the construction site and marking them. This requires a great deal of time and labor and is a cause of delay in the waterproof construction period. Further, in the above-mentioned insulating and waterproofing method, it is known that the wind pressure becomes higher as the working place becomes higher, and the wind pressure at the outer peripheral portion of the roof of the laid waterproof sheet is higher than that at the central portion. Also, the strength of the concrete varies depending on the type of concrete on the ground above and below the roof, so the number of fasteners driven in to fix the tarpaulin also varies. The wind pressure is generally expressed by the following equation. P = C · q << P: Wind pressure (Kg / m 2 ), q: Velocity pressure (Kg / m 2 ), C: Wind force coefficient >> q = 60√h ・ ・ ・ ・ h ≦ 16 q = 120 4 √ h ... h> 16 (h: height of building: m) Based on this formula, determine the position and the number of fixing brackets required to fix the laid tarpaulin. Generally, one or two fixing metal fittings are driven in per m 2 to fix the waterproof sheet to the base surface.
【０００４】 又、敷設後の防水シートの屋上外周部付近部分は、中央部よりも風圧力が高い ことが知られており、従って中央部よりも固定金具を多く打ち込み防水シートを 更に強固に固定する必要がある。 この様に固定金具は、防水シートの決められた場所に且つ必要な個数で打ち込 み、防水シートを下地面に全面的に強固に固定する必要がある。この固定金具を 打ち込む場所の位置決めは、従来は墨出し等により行い、防水シート上に固定金 具を打ち込む直線を描き、その線によって決められた位置に所定の印を付けてい くという方法で行っていた。この墨出し等により固定金具を打ち込む位置を決定 し、その位置に印を付けて施工する方法では、多大な時間と手間を要し、防水施 工の工期が遅れる原因となっていた。 従って本考案の目的は、上記従来技術の問題点を解決し、施工性に優れた防水 シートを提供することである。Further, it is known that the wind pressure around the roof outer peripheral portion of the laid tarpaulin is higher than that in the central portion, and therefore, more fixing metal fittings are driven in than in the central portion to further firmly fix the waterproof sheet. There is a need to. As described above, it is necessary to drive the fixing metal fittings to the waterproof sheet at a predetermined place and in the required number to firmly fix the waterproof sheet to the base surface. Conventionally, the location where the fixing metal fitting is driven is done by marking out, drawing a straight line for driving the fixing metal on the waterproof sheet, and making a predetermined mark at the position determined by the line. Was there. The method of deciding the position where the fixing metal fitting is to be hammered in by marking out and marking the position requires a great deal of time and labor, which causes a delay in the waterproofing work period. Therefore, an object of the present invention is to solve the above-mentioned problems of the prior art and to provide a waterproof sheet having excellent workability.
【０００５】[0005]
上記目的は以下の本考案によって達成される。即ち、本考案は、表面に施工上 の目盛りとなる模様が形成されていることを特徴とする防水シートである。 The above object is achieved by the present invention described below. That is, the present invention is a waterproof sheet having a pattern on the surface which is a scale for construction.
【０００６】[0006]
防水シートの表面に施工上の目盛りとなる模様を形成しておくことにより、接 着防水工法において、防水シート同士をその側端部において、幅４０〜５０ｍｍ の重ねしろをとって重ね溶着して接合する際に、重なり部分の間隔が分かり易く なり、シートが曲がった状態で溶接されたり、これにより皺が発生することもな い。 又、絶縁防水工法では、従来の墨出しよる手間が省け、重ねしろの取りかたは 勿論、固定金具を打ち込む位置決めが簡単になり、防水施工の工期が短縮される 。 又、上記目盛りを直線状の格子模様とすれば、防水シートを屋上の形状に合わ せ裁断するときに、直線を基準に裁断することが出来るので真っ直ぐに正確に裁 断することが容易となる。 By forming a pattern on the surface of the waterproof sheet as a scale for construction, in the adhesive waterproof method, the waterproof sheets are overlapped and welded at their side end portions with a width of 40 to 50 mm. At the time of joining, it becomes easy to understand the gap between the overlapping portions, and the sheets are not welded in a bent state, and wrinkles do not occur. In addition, the insulating and waterproofing method saves the work of the conventional marking process, simplifies the positioning of the fixing metal fitting as well as the overlap margin, and shortens the waterproofing construction period. Further, if the scale is formed in a linear grid pattern, when the waterproof sheet is cut to fit the rooftop shape, it is possible to cut based on a straight line, which makes it easy to cut straight and accurately. .
【０００７】[0007]
次に好ましい実施例を挙げて本考案を更に具体的に説明する。 本考案の防水シート１は、図１である正面図に示す如く、基本的には、防水シ ート１の一方の面に、施工上の目盛りとなる模様２が形成されていることを特徴 としている。 本考案において使用する防水シート１自体は、従来の接着シート防水工法及び 絶縁防水工法に使用されている防水シートと同様でよく、例えば、塩化ビニル系 樹脂シート、エチレン−酢酸ビニル共重合体樹脂シート、ポリエチレン樹脂シー ト、ポリプロピレン樹脂シート、合成ゴムシート等が挙げられるが、液溶着（溶 剤による接着）が容易である点からして軟質塩化ビニル樹脂製シートが最も好ま しい。 以上の如き防水シート１は、単層体でも積層体でもよいが、図２である一部切 り欠き斜視図に示す様にシート１の収縮防止の為にガラス不織布等の収縮防止材 ３を中間に挿入した積層体が好ましい。防水シート１の厚さは特に限定されない が、通常は０．５ｍｍ〜５．０ｍｍ、好ましくは１．０ｍｍ〜２．０ｍｍである 。又、長さは特に制限されず、幅が５００ｍｍ〜２，０００ｍｍ程度の長尺体で あって通常はロール状に巻かれている。 Next, the present invention will be described more specifically with reference to preferred embodiments. As shown in the front view of FIG. 1, the waterproof sheet 1 of the present invention is basically characterized in that a pattern 2 as a construction scale is formed on one surface of the waterproof sheet 1. I am trying. The waterproof sheet 1 itself used in the present invention may be the same as the waterproof sheet used in the conventional adhesive sheet waterproofing method and insulating waterproofing method, for example, vinyl chloride resin sheet, ethylene-vinyl acetate copolymer resin sheet. , Polyethylene resin sheet, polypropylene resin sheet, synthetic rubber sheet, etc., but soft vinyl chloride resin sheet is the most preferable because it is easy to liquid weld (adhesion with a solvent). The waterproof sheet 1 as described above may be a single layer body or a laminated body, but as shown in the partially cutaway perspective view of FIG. 2, a shrinkage preventive material 3 such as a glass nonwoven fabric is used to prevent the sheet 1 from shrinking. A laminate inserted in the middle is preferred. The thickness of the waterproof sheet 1 is not particularly limited, but is usually 0.5 mm to 5.0 mm, preferably 1.0 mm to 2.0 mm. Further, the length is not particularly limited, and is a long body having a width of about 500 mm to 2,000 mm and is usually wound in a roll shape.
【０００８】 上記防水シートの面に形成する施工上の目盛りとなる模様２は、防水シート１ の表面の長手方向に対して縦及び横方向に直線を交差させた格子模様状が最も好 ましいが、例えば、目盛りとなる模様が、シートの長手方向に対して等間隔の複 数の仮想平行線と、これらに直交する等間隔の複数の仮想平行線との交点にあっ てもよい。又、絶縁防水工法に使用する防水シートの場合には、固定具を打ち込 む為の位置が分かる様な、ある一定の規則を持った繰り返し模様であってもよい 。例えば、丸い点や他の小さな模様を等間隔に防水シート面に形成してもよい。 目盛りとなる模様２を形成する直線は、接着防水工法に用いる防水シートの場 合には、防水シートの最側端部から格子模様の最初の直線までの距離が重ねしろ の幅と一定の関係、例えば、重ねしろと同じ幅の位置にあるのが好ましく、絶縁 工法に用いる場合にも同様であると共に、両側端部に最も近い直線以内の直線同 士の間隔はあまり細かすぎても、大きすぎても好ましくなく、好ましくは５０〜 １，０００ｍｍの範囲の間隔である。特に、５０ｍｍ、１００ｍｍ、５００ｍｍ 等の長さの如く計算のし易い間隔か、或は固定具を打ち込む間隔が、例えば、６ ００ｍｍの場合、６００ｍｍ、３００ｍｍ、２００ｍｍ、１００ｍｍ、５０ｍｍ の如く、６００ｍｍの約数の長さの間隔の直線模様等が最適である。The pattern 2 which is a scale for construction formed on the surface of the waterproof sheet is most preferably a lattice pattern in which straight lines are crossed in the vertical and horizontal directions with respect to the longitudinal direction of the surface of the waterproof sheet 1. However, for example, the graduation pattern may be located at the intersections of a plurality of imaginary parallel lines that are equally spaced in the longitudinal direction of the sheet and a plurality of imaginary parallel lines that are orthogonal to these and are parallel to each other. Further, in the case of the waterproof sheet used for the insulation waterproof method, the repeating pattern may have a certain rule so that the position for driving the fixing tool can be known. For example, round dots or other small patterns may be formed on the waterproof sheet surface at equal intervals. In the case of the waterproof sheet used for the adhesive waterproofing method, the straight line forming the graduation pattern 2 has a constant relationship with the width of the overlapping margin from the outermost end of the waterproof sheet to the first straight line of the lattice pattern. For example, it is preferable that they are in the same width position as the overlap margin, and the same applies when used for the insulation method, and if the distance between the straight lines within the straight lines closest to both end parts is too small, It is not preferable that the distance is too large, and the distance is preferably in the range of 50 to 1,000 mm. In particular, if the distance is easy to calculate, such as the length of 50 mm, 100 mm, 500 mm, or the distance for driving the fixture is 600 mm, for example, 600 mm, 300 mm, 200 mm, 100 mm, 600 mm A straight line pattern with an interval of about several lengths is optimal.
【０００９】 特に５０ｍｍ又は１００ｍｍの間隔で防水シート表面に格子状模様２を形成し た場合、防水シートの端末のあまり部分や出隅、入り隅部分を直線的に裁断する ときに、この直線模様２を基準に真っ直ぐに且つ正確にシートを裁断することが 簡単になる。又、防水シートの側端部同士を重ねて接合する場合、その接合幅は 通常約４０ｍｍ〜５０ｍｍであるので、５０ｍｍ間隔で線が形成されていれば、 接合部分の幅の目安となり、防水シートの側端部同士の溶着が容易且つ正確とな る。 以上の如き目盛りとなる模様２の形成方法としては、グラビア印刷、スクリー ン印刷、転写紙による印刷方法や、エンボス（型押）方法が好ましく使用される 。エンボス処理では、通常、防水シート表面を加熱し、樹脂を軟化させて、模様 が施された型押し彫刻ロールで押圧し、表面にエンボス模様を形成する。In particular, when the grid-like pattern 2 is formed on the surface of the waterproof sheet at intervals of 50 mm or 100 mm, this linear pattern can be used when linearly cutting the remaining portion, the projecting corner, and the entering corner portion of the waterproof sheet. It becomes easy to cut the sheet straight and accurately on the basis of 2. Also, when the side edges of the waterproof sheet are overlapped and joined, the joint width is usually about 40 mm to 50 mm, so if lines are formed at intervals of 50 mm, the width of the joint portion becomes a standard and the waterproof sheet It is easy and accurate to weld the side edges of the. As a method of forming the pattern 2 having the scale as described above, gravure printing, screen printing, a printing method using transfer paper, and an embossing method are preferably used. In the embossing treatment, the surface of the waterproof sheet is usually heated to soften the resin and pressed by a pattern-embossing engraving roll to form an embossed pattern on the surface.
【００１０】 次に本考案の防水シートの使用例を、図３及び図４に示す絶縁防水工法を参照 して説明するが、本考案の防水シートの用途はこの絶縁防水シートに限定されな いことは当然である。 先ず、上記の如き防水シート１（１例として塩化ビニル樹脂シート）を、コン クリート、軽量発泡コンクリート、木材、或は既にゴム引きやアスファルト等で 防水処理が為されているが、既に耐久時間の過ぎた下地５の面に、図示の如く防 水シート１を被覆する。この際、下地面の凹凸による影響や、下地面から防水シ ートに移行する物質或は防水シート中の可塑剤が下地面に移行するのを防止する 為に、防水シート１と下地面５との間に発泡絶縁シート４を介在させることが好 ましい。これらの発泡絶縁シート４としては、例えば、適当な厚みのポリエチレ ン、ポリプロピレン、ポリウレタン、ポリ塩化ビニル、エチレン−酢酸ビニル共 重合体等の各種発泡体からなる絶縁発泡シートが挙げられる。 次に同様な塩化ビニル樹脂製の第一の補強シート６（この例では直径１８５ｍ ｍ、厚み１ｍｍ、中心に直径１０ｍｍの円孔を設けて有る軟質塩化ビニル樹脂シ ート製円板）を防水シート１の目盛り模様２を利用して決めた所定の位置に置き 、好ましくは防水シート面に液溶着させる。Next, an example of using the waterproof sheet of the present invention will be described with reference to the insulating waterproof method shown in FIGS. 3 and 4, but the application of the waterproof sheet of the present invention is not limited to this insulating waterproof sheet. It is natural. First, the waterproof sheet 1 (for example, a vinyl chloride resin sheet) as described above has been waterproofed with concrete, lightweight foam concrete, wood, or already rubberized or asphalt. The surface of the surplus substrate 5 is covered with the waterproof sheet 1 as shown. At this time, in order to prevent the influence of the unevenness of the base surface and the substance that transfers from the base surface to the waterproof sheet or the plasticizer in the waterproof sheet to transfer to the base surface, the waterproof sheet 1 and the base surface 5 It is preferable to interpose the foamed insulating sheet 4 between and. Examples of the foamed insulation sheet 4 include insulation foamed sheets made of various foams such as polyethylene, polypropylene, polyurethane, polyvinyl chloride, and ethylene-vinyl acetate copolymer having an appropriate thickness. Next, waterproof the same first reinforcing sheet 6 made of vinyl chloride resin (in this example, a soft vinyl chloride resin sheet disc having a circular hole with a diameter of 185 mm, a thickness of 1 mm, and a diameter of 10 mm at the center). The sheet 1 is placed at a predetermined position determined by using the scale pattern 2 and preferably liquid-welded to the surface of the waterproof sheet.
【００１１】 次に第一の補強シート６の中心の円孔に沿って、下地５に合った適当なドリル により防水シート１を貫通して下地５にまで穿孔し、例えば、直径約４〜１０ｍ ｍ、深さ約３０〜１５０ｍｍ程度の孔７を穿ち、この孔中にエポキシ樹脂等の如 く常温硬化性の樹脂を注入し、樹脂が固化する前に、ビス孔を確保し且つビスの 固定を確保する為の、例えば、ナイロンプラグ８を挿入し、引き続き、例えば、 金属製の皿形状であって防錆塗料（塩化ビニル樹脂製がよい）が塗布されている 押え板９（この例では厚さ１ｍｍ、直径６５ｍｍで中心に５ｍｍのビス孔が設け られている鋼板）を載置し、ビス１０を押え板の孔を通して下地５にまでねじ込 み、押さえ板９をしっかりと固定する。この間にエポキシ樹脂は固化しており、 固定が十分に行われる。 次に第二の補強シート１１（この例では直径１，２００ｍｍ、厚み１ｍｍの円 板状軟質塩化ビニルシート）の面にＴＨＦを全面的に塗布し、第一の補強シート ６及び押さえ板９を十分被覆している状態で押さえ板９、第一の補強シート６及 び防水シート１の面に接着させる。続いて必要に応じて第二の補強シート１１の 周囲に塩化ビニル樹脂のＴＨＦ溶液からなるシーラント１２を塗布して目止して 漏水を完全に防止する。Next, along the circular hole at the center of the first reinforcing sheet 6, the waterproof sheet 1 is pierced through the waterproof sheet 1 with a suitable drill suitable for the underlayer 5 to reach the underlayer 5, for example, a diameter of about 4 to 10 m. m, a hole 7 having a depth of about 30 to 150 mm is formed, and a room temperature curable resin such as an epoxy resin is injected into this hole to secure a screw hole and fix the screw before the resin is solidified. For example, a nylon plug 8 is inserted in order to ensure that the holding plate 9 (in this example, a metal dish shape and rust preventive paint (preferably made of vinyl chloride resin) is applied. A steel plate having a thickness of 1 mm, a diameter of 65 mm, and a screw hole of 5 mm at the center is placed, and the screw 10 is screwed into the base 5 through the hole of the holding plate, and the pressing plate 9 is firmly fixed. During this time, the epoxy resin has solidified and is sufficiently fixed. Next, the entire surface of the second reinforcing sheet 11 (in this example, a disk-shaped soft vinyl chloride sheet having a diameter of 1,200 mm and a thickness of 1 mm) is coated with THF, and the first reinforcing sheet 6 and the pressing plate 9 are applied. It is adhered to the surfaces of the pressing plate 9, the first reinforcing sheet 6 and the waterproof sheet 1 in a sufficiently covered state. Subsequently, if necessary, a sealant 12 composed of a THF solution of vinyl chloride resin is applied around the second reinforcing sheet 11 to stop the sealant 12 to completely prevent water leakage.
【００１２】 次に具体的実施例を挙げる。具体例１（絶縁防水工法における使用） 厚さ０．５ｍｍのグレーに着色されたポリ塩化ビニル樹脂製のシートの表面に 、縦横５０ｍｍの間隔で直線状の格子模様を濃いグレー系のインクを用いてグラ ビア印刷で形成した。 このシートの裏面に、補強層として厚さ０．２ｍｍのガラス不織布を重ね、更 に該不織布面に厚さ０．８ｍｍのポリ塩化ビニル樹脂製の裏打ちシートを積層し 、表面に格子状模様が印刷された厚さ１．４ｍｍの本考案の防水シートを作成し た。 この防水シートを屋上コンクリート面に、発泡ポリエチレンシートを介して屋 上面全面に敷設していき、防水シートの側端部には接合部分として４０〜５０ｍ ｍの重ねしろをとり、表面に印刷された線を基準に溶着して接合していく。Next, specific examples will be described. Example 1 (Use in insulation and waterproofing method) On the surface of a 0.5 mm-thick sheet of polyvinyl chloride resin colored in gray, a linear grid pattern with dark gray ink is used at intervals of 50 mm in length and width. It was formed by gravure printing. On the back side of this sheet, a glass non-woven fabric having a thickness of 0.2 mm is laminated as a reinforcing layer, and a backing sheet made of polyvinyl chloride resin having a thickness of 0.8 mm is further laminated on the non-woven fabric surface. A printed waterproof sheet of the present invention having a thickness of 1.4 mm was prepared. This tarpaulin was laid on the rooftop concrete surface over the entire rooftop surface via a polyethylene foam sheet, and a 40-50 mm overlap margin was added as a joint at the side edge of the tarpaulin and was printed on the surface. Weld and join based on the wire.
【００１３】 次に、屋上面ほぼ中央部分の防水シート面の印刷部分の任意の縦及び横線の交 点を基準点とし、そこから縦及び横方向に１，２００ｍｍ間隔に固定金具を打ち 込む為に、防水シートを貫通し下地コンクリート面までドリルで穿孔し、又、基 準点から縦横６００ｍｍ移動した点をもう一つの基準点とし、そこから同様に縦 横１，２００ｍｍの間隔で同様な穴を穿孔する。 屋上外周部付近においては、風圧力が中央部分よりも高く、防水シートが浮き 上がり易いので、外周端部から６００ｍｍ以内に周囲を囲む様に６００ｍｍ間隔 で固定具を設置する為の穴を穿孔し、更にその内側に更に１列で６００ｍｍ間隔 で穿孔する。 これらの穴の面に、円形状でその中心に穴が設けられたポリ塩化ビニル樹脂製 の第一の補強シートを液溶着により防水シートと接着させ、常温硬化性エポキシ 樹脂を孔中に注入した後プラグを穴に打ち込み、ポリ塩化ビニル樹脂製シートで 被覆された鋼板からなる固定金具を被せた後に、ビスで固定し、その上にポリ塩 化ビニル樹脂製の中央部が盛り上がったキャップ状で円形の第二の補強シートを 固定具の上に被覆し、固定具の頭部と防水シートとの重なり部分との液溶着によ り接着し、更に第二の補強シートの外周をシーリングして防水施工を完了する。Next, in order to drive the fixing metal fittings at 1,200 mm intervals in the vertical and horizontal directions from the reference point at the intersection of arbitrary vertical and horizontal lines on the printed portion of the waterproof sheet surface in the central portion of the rooftop. Then, drill a hole through the waterproof sheet to the concrete surface of the foundation, and use the point that moved 600 mm in length and width from the reference point as another reference point, and from that point, make similar holes at intervals of 1,200 mm in length and width. Perforate. The wind pressure is higher near the outer periphery of the roof than in the central portion, and the waterproof sheet easily floats up.Therefore, perforate holes for installing fixtures at 600 mm intervals so as to surround the periphery within 600 mm from the outer edge. , And one more row is drilled on the inside at 600 mm intervals. The first reinforcing sheet made of polyvinyl chloride resin, which is circular and has a hole at its center, is adhered to the waterproof sheet by liquid welding on the surface of these holes, and room temperature curable epoxy resin is injected into the holes. The rear plug is driven into the hole, covered with a fixing bracket made of a steel sheet covered with a polyvinyl chloride resin sheet, and then fixed with a screw, and a cap-shaped cap made of polyvinyl chloride resin is raised on top of it. Cover the fixing tool with a circular second reinforcing sheet, bond the head of the fixing tool and the overlapping part of the waterproof sheet by liquid welding, and then seal the outer circumference of the second reinforcing sheet. Complete waterproof construction.
【００１４】具体例２（接着防水工法における使用） 防水すべき屋上の下地コンクリート面に、表面に５０ｍｍ間隔の格子状模様が 印刷された長尺状の塩化ビニル樹脂製防水シートを並べて施設する。この時、防 水シート同士の接合部分の重ねしろの幅が約４０ｍｍになる様にシート表面に印 刷された格子模様のシート端部分から１本目の線単から５０ｍｍに合わせて重ね る。次に、仮設した防水シートを部分的に捲りながら、エポキシ樹脂系の接着剤 をコンクリート面に塗工していき、オープンタイムを取り接着剤の溶剤を揮散さ せた後防水シートをコンクリート面に接着していく。この様にして防水シートを 屋上コンクリート面に接着した後、約４０ｍｍの重ねしろを取った防水シートの 接合部分を加熱してシートを融解させて接着させる熱融着法、又は溶剤により防 水シートを溶解させて接着させる液溶着法によって接着接合させる。最終的にパ ラペット等の屋上の端部の防水処理を行い、屋上全体の防水施工を仕上げる。 この様に防水シート表面に施工上の目盛りが予め形成されていることにより、 シート端部から５０ｍｍの直線に合わせた防水シート同士を重ねることが出来、 従来の様に定規等で重ねしろの幅を測る必要がなくなり防水施工の簡略化が可能 となった。 Concrete Example 2 (Use in Adhesive Waterproofing Method) A long vinyl chloride resin waterproof sheet having a grid pattern printed at 50 mm intervals is lined up on the concrete surface of a rooftop to be waterproofed. At this time, the water-proof sheets are overlapped so that the width of the overlap portion of the joint portion between the water-proof sheets is about 40 mm and the first line of the sheet is 50 mm from the edge portion of the grid pattern printed on the sheet surface. Next, while partially rolling up the temporary waterproof sheet, an epoxy resin adhesive was applied to the concrete surface to allow open time to evaporate the solvent of the adhesive and then apply the waterproof sheet to the concrete surface. Adhere. After adhering the waterproof sheet to the rooftop concrete surface in this way, heat-sealing method in which the joint part of the waterproof sheet with a margin of about 40 mm is heated to melt and adhere the sheet, or the waterproof sheet by a solvent Are melted and bonded by a liquid welding method. Finally, waterproofing the rooftop edge such as parapets will be completed to complete the waterproofing of the rooftop. In this way, since the scales for construction are pre-formed on the surface of the waterproof sheet, it is possible to stack the waterproof sheets that are aligned with a straight line of 50 mm from the sheet end, and the width of the overlap can be overlapped with a ruler as in the past. Since it is not necessary to measure, it is possible to simplify waterproof construction.

以上の如き本考案によれば、防水シートの表面に施工上の目盛りとなる模様を 形成しておくことにより、接着防水工法において、防水シート同士をその側端部 において、幅４０〜５０ｍｍの重ねしろをとって重ね溶着して接合する際に、重 なり部分の間隔が分かり易くなり、シートが曲がった状態で溶接されたり、これ により皺が発生することもない。 又、絶縁防水工法では、従来の墨出しよる手間が省け、重ねしろの取りかたは 勿論、固定金具を打ち込む位置決めが簡単になり、防水施工の工期が短縮される 。 又、上記目盛りを直線状の格子模様とすれば、防水シートを屋上の形状に合わ せ裁断するときに、直線を基準に裁断することが出来るので真っ直ぐに正確に裁 断することが容易となる。 According to the present invention as described above, by forming a pattern as a scale for construction on the surface of the waterproof sheet, in the adhesive waterproof method, the waterproof sheets are overlapped at their side end portions with a width of 40 to 50 mm. When overlapping and welding by taking a margin, it becomes easier to understand the gap between the overlapping portions, and the sheet is not welded in a bent state, and wrinkles do not occur. In addition, the insulating and waterproofing method saves the work of the conventional marking process, simplifies the positioning of the fixing metal fitting as well as the overlap margin, and shortens the waterproofing construction period. Further, if the scale is formed in a linear grid pattern, when the waterproof sheet is cut to fit the rooftop shape, it is possible to cut based on a straight line, which makes it easy to cut straight and accurately. .
