この発明は積層防水施工法に関し、詳しくは下地面の防
水を行うため、２以上の防水シートを積層接着する際の
施工法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a laminated waterproof construction method, and more particularly to a construction method for laminating and bonding two or more waterproof sheets together in order to waterproof a base surface.
従来、建築構造物、貯水槽等の下地面の防水施工を行う
場合、下地面上に防水シートを展開して貼り付けること
が行われることがある。2. Description of the Related Art Conventionally, when waterproofing the subsurface of a building structure, water tank, etc., a waterproof sheet is sometimes spread out and pasted on the subsurface.
この防水シートを用いた防水施工法には、一枚の防水シ
ートを継ぎ合わせていくことにより広い面積を防水する
いわゆる単７層張り施工法と、二枚以上の防水シートを
重ねて貼り付けてい〈複層張り施工法とがある。Waterproofing construction methods using this tarpaulin sheet include the so-called 7-layer construction method, which waterproofs a wide area by piecing together a single sheet, and the method in which two or more tarpaulin sheets are pasted together. (There is a multi-layered construction method.
上記のうち前者の単層張り施工法は、広大な下地面に比
較的短期間で防水施工できる利点を有するが、一層張妙
に用いられるシートは厚さ１．０簡前後の高分子シート
であるから、厚さが薄く、強度的に破孔を生じやすく、
又、シート端部の継目部分における貼り合わせ箇所の水
密性の確保が困難であり、接合部より漏水しやすいとい
った問題があった。Among the above, the former single-layer construction method has the advantage of being able to waterproof a vast base surface in a relatively short period of time, but the sheet used for even greater construction is a polymer sheet with a thickness of about 1.0 cm. Because it is thin, it is easy to break holes due to its strength,
In addition, it is difficult to ensure watertightness at the joints at the ends of the sheets where they are bonded together, and there is a problem in that water leaks more easily than at the joints.
一方、後者の複層張りは上下層の防水シートの接合部分
を互いにずらせることによって単層張、りのような漏水
の危険性は回避できるが、下地面と下層の防水シートを
溶剤系の接着剤で接着貼り合わせた後、上層の防水シー
トを溶剤系の接着剤で下層の防水シート上に貼り合わせ
る場合、下地面と下層の防水シート間の接着剤の溶剤に
より下層の防水シートが膨潤し、いわゆるフクレを生じ
て上層の防水シートを水密に貼り合わせるのが困難とな
ることがあり、又、このフクレにより防水シートの端部
間の接続貼り合わせも確実に行えず、完全な防水性が得
られなくなるといった欠点を有していた。On the other hand, in the latter case, the risk of water leakage can be avoided by shifting the joints of the upper and lower waterproof sheets to each other to avoid the risk of water leakage. After bonding with adhesive, if the upper layer waterproof sheet is attached to the lower layer waterproof sheet with a solvent-based adhesive, the lower layer waterproof sheet may swell due to the solvent of the adhesive between the base surface and the lower layer waterproof sheet. However, so-called blisters may occur, making it difficult to watertightly bond the upper layer of the waterproof sheet together.Also, due to these blisters, it may not be possible to reliably bond the ends of the waterproof sheet together, resulting in complete waterproofness. It had the disadvantage that it became impossible to obtain
さらに、上記いずれの場合も、防水シートは高分子製シ
ートであるから、展開する際、下層の防水シートと上層
の防水シートとの間に空気を内包しやすく、シート間の
接着も完全に行い難いといった欠点があった。Furthermore, in all of the above cases, since the tarpaulin sheet is a polymer sheet, when it is unfolded, it is easy to trap air between the lower layer tarpaulin sheet and the upper layer tarpaulin sheet, and the adhesion between the sheets is also completely ensured. It had the drawback of being difficult.

及び網目状シートをこの順序で積層して成る第２防水シ
ートを、該第２防水シートの網目状シート面を介して貼
り合わせることを特徴とするものである。The purpose of this invention is to provide a laminated waterproofing construction method that allows for complete waterproofing without introducing air into the joint interface of each layer in the multilayer construction method. A first waterproof sheet that has been subjected to an adhesive treatment that is non-tacky at room temperature is adhered to the surface of the tacky adhesive layer applied on the base surface, and then to the surface of the first waterproof sheet, A second waterproof sheet, which is formed by laminating a polymer sheet, a self-adhesive layer, and a mesh sheet in this order, is bonded together via the mesh sheet surface of the second waterproof sheet.
次に、この発明を実施の状態を示す説明図によって説明
する。Next, the present invention will be explained with reference to explanatory diagrams showing the state of implementation.

網目状シート４０をこの順序で積層して成る第２防水シ
ート４を、この第２防水シート４の網目状シート４Ｃを
介して貼り合わせていくのである。The method of the present invention is to apply a solvent-based or non-solvent adhesive to the base surface 1 when pasting the waterproofing sheet on the base surface 1, and it remains sticky even after drying to the touch. On top of this, a first waterproof sheet 3 whose both sides have been subjected to adhesive treatment 3A which is non-adhesive at room temperature is spread and adhered to the base surface 1, and then, On this first waterproof sheet 3, a second waterproof sheet 4 formed by laminating a polymer sheet 4A, a self-adhesive adhesive layer 4B, and a mesh sheet 40 in this order is placed on the mesh sheet of this second waterproof sheet 4. They are pasted together using 4C.

４の高分子シート４Ａは、例えば、加硫コムシート、塩

アスファルトルーフイングなど、高分子シートと呼ばれ
るもの全般のものが適合する。In the above, the polymer sheet 4A of the first waterproof sheet 3 and the second waterproof sheet 4 is a polymer sheet such as a vulcanized comb sheet, a plastic sheet such as vinyl chloride, polyethylene, or asphalt roofing. General items are suitable.
又、第２防水シート４の網目状シー）４０Ｆｉ。Also, the mesh-like seam of the second waterproof sheet 4) is 40Fi.
耐水性のある繊維又はフィルムを格子状に組合わせたも
のであり、第２防水シート４に対し、自着性接着層４Ｂ
を介して接着されている。It is a combination of water-resistant fibers or films in a lattice pattern, and a self-adhesive adhesive layer 4B is attached to the second waterproof sheet 4.
It is glued through.
この発明は以上のように構成されているから、下地面上
に第１防水シートを貼り付けた後は、第２防水シートを
貼り付けるための接着剤を別に必要とせず、第１防水シ
ートの膨潤によるフクレを生じさせることなく、第２防
水シートを簡単に貼り付けていくことができ、又、火災
の危険もなく、人畜にも無害である。Since this invention is configured as described above, after pasting the first waterproof sheet on the base surface, there is no need for a separate adhesive for pasting the second waterproof sheet, and the first waterproof sheet can be attached to the base surface. The second waterproof sheet can be easily attached without causing blisters due to swelling, and there is no danger of fire and is harmless to humans and animals.
さらに、第２防水シートに社網目状シートが積層されて
いるので、第１防水シート上に第２防水シートを貼り付
ける際、網目状シートの網目を伝って層間の空気が逃が
されるため、空気を抱え込むことがなく、空気の包み込
みによるフクレも防止できる。Furthermore, since the mesh sheet is laminated on the second tarpaulin sheet, when the second tarpaulin sheet is pasted on the first tarpaulin sheet, the air between the layers escapes through the mesh of the mesh sheet. It also prevents blisters caused by air entrapment.
又、この発明の方法によれば、第１防水シートと第２防
水シートは、自着性接着層により接着されて一体化され
るため確実な水密性が確保できる。Further, according to the method of the present invention, the first waterproof sheet and the second waterproof sheet are bonded and integrated by the self-adhesive adhesive layer, so that reliable watertightness can be ensured.
