この発明は防水シートの下地面への敷設構造に屋根、駐
車場などに施工される防水シートの下地面を被覆してな
る敷設構造に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a construction in which a waterproof sheet is installed on a subsurface, and a waterproof sheet is installed on a roof, a parking lot, etc. and covers the subsurface.
（従来の技術）
従来、ゴム製あるいは合成樹脂製防水シートの下地面へ
の敷設構造は多数提案されている。その代表的なものと
しては、第１番目に、下地面又は防水シートの少なくと
も一面に接着剤を塗布することによる接着敷設構造があ
る。(Prior Art) Conventionally, many structures have been proposed in which a waterproof sheet made of rubber or synthetic resin is laid on the underlying surface. The first typical example is an adhesive laying structure in which an adhesive is applied to at least one surface of a base surface or a waterproof sheet.
また、第２番目として防水シートが塩化ビニール樹脂製
である場合、表面を塩化ビニール樹脂製シートにて被覆
した鉄板を下地面にアンカーにて固定し、鉄板を介して
下地面に防水シートを敷き、鉄板の被覆用塩化ビニール
シートと防水シートとの間に塩化ビニール樹脂溶着剤を
塗布し、防水シートを下地面に敷設貼着せしめている。Second, if the waterproof sheet is made of vinyl chloride resin, an iron plate whose surface is covered with a vinyl chloride resin sheet is fixed to the base surface with anchors, and the waterproof sheet is laid on the base surface through the iron plate. A vinyl chloride resin adhesive is applied between the vinyl chloride sheet for covering the iron plate and the waterproof sheet, and the waterproof sheet is laid and adhered to the underlying surface.
また第３番目のものとして、防水シート端部において、
下地面に固定した金具に防水シートを接着する敷設構造
がある。Also, as a third thing, at the end of the waterproof sheet,
There is an installation structure in which a waterproof sheet is glued to metal fittings fixed to the underlying surface.
ところで最近、接着剤による防水シートの敷設に替えて
、例えば特開昭６１−１７２９４６号公報に開示されて
いるように、下地面にアンカーを固定し、アンカーの首

可塑性樹脂製のアンカーを防水シートを貫通して下地に
打ち込み、アンカーを防水シートに熱融着する敷設手段
が開示されている。By the way, recently, instead of laying a waterproof sheet with adhesive, for example, as disclosed in JP-A-61-172946, an anchor is fixed to the base surface and the neck of the anchor is fitted to the neck of this anchor. A method has been proposed for fixing the waterproof sheet by sandwiching the waterproof sheet between the cap body and the cap body. An installation method is disclosed in which the anchor is driven into the waterproof sheet and the anchor is thermally fused to the waterproof sheet.
（発明が解決しようとする課題）
前記接着剤による接着敷設は、接着に先立って接着面の
全面を清浄にする手段、さらに接着剤の塗布など作業面
で手数がかかり、また改修工事では、下地面の老化ある
折には、これに対処する必要があり、さらに下地面が湿
っている折には、接着施工工事が不可能であった。(Problems to be Solved by the Invention) Adhesive installation using the adhesive described above requires time-consuming work such as cleaning the entire surface of the bonding surface prior to bonding, and applying the adhesive. When the ground ages, it is necessary to deal with this problem, and furthermore, when the subsurface is wet, adhesive construction work is impossible.
前記第２番目として開示した敷設貼着構造は、鉄板を塩

布しないと部分的な接着不良を発生せしめる問題点があ
った。The installation and adhesion structure disclosed as the second item above requires the labor of covering the steel plate with a vinyl chloride sheet, and the risk of the operator inhaling the solvent is similar to the installation adhesive structure disclosed in the first item, which involves applying adhesive to the entire surface. Moreover, there is a problem in that if the adhesive is not applied uniformly, partial adhesion failure occurs.
また、前記第３番目として開示された防水シートの敷設
構造は、防水シート自体にしわあるいはたるみが発生し
やすく、この点外観を大きく損い、このしわあるいはた

ン処理を困難なものとする欠点があった。In addition, the construction of the tarpaulin sheet disclosed in the third aspect of the invention is likely to cause wrinkles or sag in the tarpaulin sheet itself, which greatly impairs the appearance. However, there was a drawback in that it made it difficult to perform a zip-in process.
また、前記、特開昭６１−１７２９４６号公報にて開示

め、・防水性の面で、この孔部の存在にて不安が残る。In addition, in the waterproof sheet installation structure disclosed in Japanese Patent Application Laid-open No. 61-172946, the anchors are fixed to the underlying surface, the cap body is fitted to the anchors, and the anchor head Additional work is required for heat fusing. It is true that compared to the adhesive structure of waterproof sheets,
Although the work has been simplified to some extent, the labor involved in laying the cables still remains. Furthermore, in the waterproof sheet installation structure disclosed in Japanese Patent Application Laid-Open No. 61-172947, in addition to the trouble of heat-sealing the anchors to the waterproof sheet, the waterproof sheet has holes for passing the anchors through. Because it is perforated, there are concerns about its waterproofness.

ClothAlso, when used as the waterproof cover 2 on the back side of the waterproof sheet 1 (see Figure 1), weather resistance is not so important, and water-resistant materials such as polyethylene (P
E) A sheet with a thickness of 0.15 to 0.8 mm is used. On the other hand, when used on the front side of waterproof sheet 1 (
A material with excellent weather resistance is used, such as a material of the same quality as the waterproof sheet 1 (see Fig. 2).

下のものが望ましい。Note that the piece-shaped or band-shaped magnetic material or iron material installed on the side of the tarpaulin sheet 1 only has to function to attract magnetic force, and the strength can be supplemented by the tarpaulin sheet 1 and the waterproof cover 2. , the thickness of these members is 0.
A thickness of about 0.05 to 0.5 mm is sufficient. In contrast,
When installing these members on the base 6 side, there is nothing to reinforce these members, so a certain level of strength is required.
A thickness of at least 0.55 on is required. If these members are not embedded in the base 6 (
(See Fig. 6), the thickness of the member is expressed as a convex portion directly on the underlying surface, which may cause deterioration of the appearance, so it is desirable that the thickness is 0.5111 m or less.

ある。In addition, the magnetic material used is not particularly limited, but the magnetic attraction force is usually 2000 k.
gf/rn2 or higher is desirable. In other words, the rate at which a waterproof sheet placed on the roof of a building is torn off by the wind is approximately 1350 kgf/m2, even when the wind pressure is locally extremely high during boat fishing. Therefore, the above figures include a large safety factor.

例として挙げることができる。In the embodiment shown in FIG. 5, in which iron powder 9 or magnet powder 5 is mixed into the waterproof sheet 1 in advance, these powders need to account for 50% or more of the waterproof sheet in order to exert a sufficient magnetic force. . However, if the amount of powder is too large, the waterproof effect of the waterproof sheet will be impaired. Therefore, it is desirable that the content be 95% by weight or less. More specifically, a rubber waterproof sheet comprising 1 part of chlorinated butyl rubber 703J, 30 parts by weight of chlorosulfonated polyethylene, 420 parts by weight of iron powder, and 3 parts by weight of carbon can be cited as an example.

は容易にこれを伸し、修正することも可能である。(Effect of the invention) This invention prevents direct blows and shocks from being applied to the tarpaulin sheet by stabilizing the tarpaulin sheet with the magnetic attraction force of the magnet when it is laid on the base surface. Since there is no need to drill any holes etc. for installation on the tarpaulin, there is no risk of damaging the tarpaulin.
There is no intrusion of trapped water due to this, and furthermore, the work of laying the waterproof sheet can be done simply, quickly, and easily. In addition, positional correction is the first priority, and wrinkles, sagging, etc. that occur after installation can be easily smoothed out and corrected.

なる。In addition, by equipping the entire surface of the tarpaulin with magnetically attractable members, the tarpaulin can be laid evenly and stably over the entire surface, and by scattering the magnetically attractable members, the cost is low, and the tarpaulin is lightweight. This will greatly contribute to the development of

設作業を迅速、簡易に行うことができる。In addition, magnetically attracting members are equipped in a band-like manner over the entire surface of the tarpaulin.
Correspondingly, in a configuration in which a strip-shaped magnetized member is also provided on the base surface, the installation strength is increased due to the parallel arrangement of both strip-shaped members, and the arrangement in which both strip-shaped members are arranged in an intersecting manner increases the installation strength. As a result, the waterproof sheet can be installed quickly and easily without any positional restrictions.

価な敷設工事が期待できる。In addition, when the strip or band-shaped magnetic member installed on the tarpaulin side is simply placed on the surface of the tarpaulin side, no special processing is required on the tarpaulin sheet, and the work of laying the tarpaulin sheet is simple. It is expected that the installation work will be done at a low cost.
