Description

防水下地への防水シートの固定方法としては、防水シートを全面接着する方法に限るものではなく、他の方法の一つとしては、間隔をあけた複数箇所に固定部を分散させることで、防水下地の伸縮等による悪影響が防水シートに及ぶのを緩和できるようにした方法〔所謂「絶縁工法」（機械的固定方法）〕があり、本発明は、この「絶縁工法」に使用できる防水シート固定具に関するものであり、更に詳しくは、防水下地の上に沿って設けられる防水シートを、前記防水下地に固定する防水シート固定具に関する。 The method of fixing the waterproof sheet to the waterproof base is not limited to the method of bonding the entire surface of the waterproof sheet, and as another method, the waterproof portion is dispersed by dispersing the fixing portion at a plurality of spaced places. There is a method (so-called "insulation method" (mechanical fixing method)) which can mitigate that the adverse effect due to the expansion and contraction of the ground extends to the waterproof sheet, and the present invention fixes the waterproof sheet which can be used for this "insulation method". More particularly, the present invention relates to a waterproof sheet fixing device for fixing a waterproof sheet provided along a waterproof substrate to the waterproof substrate.

従来、この種の防水シート固定具Ｌとしては、図１８に示すように、金属薄板素材をプレス成形によって立体的な円板形状に成形して構成してあるものがあった（例えば、特許文献１参照）。 Heretofore, as this type of waterproof sheet fixing tool L, as shown in FIG. 18, there has been one in which a thin metal plate material is formed into a three-dimensional disc shape by press forming (for example, patent document 1).

この防水シート固定具Ｌは、円板の中央部分２０と外周部分２２とが防水下地１側に位置し、それらの間に位置する平面部分２１は防水下地１から離間する方向に膨出した形状に構成してあり、中央部分２０には、固定ネジ部材３を挿通するネジ挿通孔２０ａが設けられ、平面部分２１は、防水シート２に対する接着面２１ａとして構成され、外周部分２２は、防水下地１に対する接地部２２ａとして構成されている。 The waterproof sheet fixing member L has a shape in which the central portion 20 and the outer peripheral portion 22 of the disc are located on the waterproof base 1 side, and the flat portion 21 located between them bulges in the direction away from the waterproof base 1 The central portion 20 is provided with a screw insertion hole 20a through which the fixing screw member 3 is inserted, the flat portion 21 is configured as an adhesive surface 21a for the waterproof sheet 2, and the outer peripheral portion 22 is a waterproof foundation It is comprised as 1st with respect to the earthing | grounding part 22a.

防水シート固定具Ｌの防水下地１への取り付けは、次の要領で行うものである。防水下地１上の所定位置に防水シート固定具Ｌを載置して、接地部２２ａが防水下地１の上面に当接した状態し、引き続き、ネジ挿通孔２０ａに固定ネジ部材３を挿通して、防水下地１に対してねじ込む。この結果、接地部２２ａと中央部分２０とが防水下地１側に押し付けられた状態で固定される。

特開２００６−１８３３９４号公報（図１、図２、図５）Unexamined-Japanese-Patent No. 2006-183394 (FIG. 1, FIG. 2, FIG. 5)

上述した従来の防水シート固定具によれば、防水シートの局部を接着して防水下地に固定するものであるから、接着されていない部分に関しては防水下地上で上下に多少の移動が許容されている。
また、防水シートの上面側は、外環境に曝されているから、防水シートの上面近傍部分に沿って風が吹くこともあり、それに伴って、防水シートの上面側に発生する負圧領域の影響で、防水シートに揚力が作用することがある。According to the conventional waterproof sheet fixing device described above, since the local part of the waterproof sheet is adhered and fixed to the waterproof base, some movement is allowed up and down on the waterproof base with respect to the non-bonded part There is.
In addition, since the upper surface side of the waterproof sheet is exposed to the external environment, wind may blow along the upper surface of the waterproof sheet, and the negative pressure region generated on the upper surface side of the waterproof sheet accordingly. Under the influence, lift may act on the tarpaulin.

このように、防水シートに対して揚力が作用すると、防水シートは、接着されてない部分が上下方向や横方向に移動するバタつき（フラッタリング）を生じ、その動きは、あたかも水面の波のごとく、風上から風下に向かって移動していく。その際、防水シートから防水シート固定具に伝わる力によって、固定ネジ部材には、振動や回転力等が繰り返して作用する虞がある。 As described above, when lift is applied to the waterproof sheet, the waterproof sheet causes fluttering in which the unbonded portion moves vertically and horizontally, and the movement is as if it were a wave of the water surface. As you move from the windward to the windward. At that time, due to the force transmitted from the waterproof sheet to the waterproof sheet fixing tool, there is a possibility that vibration, rotational force and the like repeatedly act on the fixing screw member.

その結果、防水シート固定具を固定している固定ネジ部材は、上述の振動や回転力の作用によって緩むことがあり、確実な固定状態を維持できなく可能性がある。 As a result, the fixing screw member fixing the waterproof sheet fixing member may be loosened by the action of the above-mentioned vibration or rotational force, and there is a possibility that the fixed fixing state can not be maintained.

この問題点を解消するには、例えば、防水シート固定具のネジ層通孔を、固定ネジ部材の軸部外径より大きめに設定したルーズホールとして形成し、防水シート固定具を、ルーズホールの遊び寸法の範囲内で、固定ネジ部材に対して径方向に移動できたり、固定ネジ部材周りに回転できるように支持することが考えられる。
これによって、防水シートから防水シート固定具に伝わる前記振動や回転力が、固定ネジ部材に伝わり難くなる。
しかし、その反面、防水下地に対して防水シート固定具が相対移動できるようになると、防水下地上の多数の防水シート固定具設置箇所の内の複数箇所において、風の影響によって防水シート固定具が変位したままになる事態が生じる。それに伴って、防水シート固定具によって支持されている防水シートは、ある部分では、強く引っ張られた状態になり、別の部分では、弛んだ状態になり、防水シートそのものに対する応力集中や、シワが生じたままになる虞がある。
その結果、防水シートが損傷・劣化し易くなり、耐久性が低下する問題点がある。In order to solve this problem, for example, the screw layer through hole of the waterproof sheet fastener is formed as a loose hole set larger than the outer diameter of the shaft portion of the fixing screw member, and the waterproof sheet fastener is a loose hole. It is conceivable to provide support so as to be able to move radially relative to the locking screw or to be able to rotate around the locking screw within the range of the idle dimensions.
By this, the said vibration and rotational force transmitted to a waterproof sheet fixing tool from a waterproof sheet become difficult to be transmitted to a fixing screw member.
However, on the other hand, when the tarpaulin fastener can move relative to the waterproof foundation, the tarpaulin fastener is affected by the wind at a plurality of locations among the many tarpaulin fixture installation locations on the waterproof foundation. A situation occurs in which displacement remains. Along with this, the waterproof sheet supported by the waterproof sheet fixing member is in a strongly pulled state in one part, and in a loose part in another part, causing stress concentration on the waterproof sheet itself, and wrinkles. There is a risk that it will continue to occur.
As a result, the waterproof sheet is likely to be damaged or deteriorated, and there is a problem that the durability is lowered.

従って、本発明の目的は、上記問題点を解消し、風が吹いても固定ネジ部材が緩み難く、より確実な固定状態を維持できながら、防水シートの耐久性の低下防止を図れる防水シート固定具を提供するところにある。 Therefore, it is an object of the present invention to solve the above-mentioned problems, and it is difficult to loosen the fixing screw member even when the wind blows, and it is possible to prevent the decrease in durability of the waterproof sheet while securing a more secure fixing state. To provide tools.

また、バネ部材を備えているから、防水下地に固定した第１部材に対して、第２部材が移動しても、両者の初期連結状態に戻すように付勢力を作用させることができる。従って、第２部材に固定されている防水シートも、防水下地上に設置した初期設置状態戻すことができ、防水シート全体として局部に圧縮力や引張力が残ったままになったり、シワがよったままになることを防止できるようになる。
その結果、風が吹いても、防水シートを防水下地に確実な固定状態を維持した状態に固定でき、且つ、防水シートの耐久性の低下を防止できるようになる。
また、バネ部材の弾性変形能を有効に利用して、防水シート固定具としての構造の簡単化、及び、部品点数の減少化とコストダウンを実現することができる。 According to the present invention, since the first member and the second member are relatively movably connected by the spring member , the first member is fixed to the waterproof base and the waterproof sheet is fixed to the second member. The waterproof sheet can be movably supported on the waterproof base.
Therefore, the vibration and rotational force transmitted from the waterproof sheet to the waterproof sheet fixing tool under the influence of wind pressure and the like can be buffered by the relative movement between the first member and the second member, and the first member is fixed to the waterproof base. For example, the fixing screw member can be prevented from being loosened.
Further, since the spring member is provided, the biasing force can be applied to the first member fixed to the waterproof base so as to return to the initial connection state of both members even if the second member moves. Therefore, the waterproof sheet fixed to the second member can also be returned to the initial installation state installed on the waterproof base, and the compressive force or tensile force remains in the local portion as the whole waterproof sheet, or wrinkles may occur. You will be able to prevent your being left alone.
As a result, even when the wind blows, the waterproof sheet can be fixed to the waterproof base in a state of being securely fixed, and the reduction in the durability of the waterproof sheet can be prevented.
Further, the elastic deformation ability of the spring member can be effectively used to realize simplification of the structure as the waterproof sheet fixing tool , and reduction in the number of parts and cost reduction.

屋根下地１への防水シート２の固定については、次の手順によって実施することができる。
［１］屋根下地１の上の所定箇所に、シート固定具Ｋ１をそれぞれ固定する。
シート固定具Ｋ１の固定は、ネジ挿通孔７に挿通した固定ネジ部材３を、屋根下地１にねじ込むことで行う。
［２］各シート固定具Ｋ１の上から防水シート２を被せ、防水シート２の上方から、電磁誘導加熱装置等によってシート固定具Ｋ１を加熱することでホットメルト接着層８ａを溶かして接着固定する。About fixation of the waterproof sheet 2 to the roof base 1, it can implement by the following procedure.
[1] The sheet fixing tool K1 is fixed to a predetermined place on the roof base 1.
The sheet fixing tool K1 is fixed by screwing the fixing screw member 3 inserted into the screw insertion hole 7 into the roof foundation 1.
[2] Cover the waterproof sheet 2 from the top of each sheet fixing tool K1 and melt the hot melt adhesive layer 8a from above the waterproof sheet 2 by heating the sheet fixing tool K1 with an electromagnetic induction heating device etc. .

以上のような防水シート固定状態においては、板バネ部６が連結機構Ｊと復帰機構Ｒとの機能を果たすことができるから、屋根下地１に固定された第１部材４に対して、第２部材５とそれに接着された防水シート２とを、移動自在に連結すると共に、その移動を元の位置に戻すことが可能となる。
その移動に関しては、屋根下地１表面に沿う方向、ネジ挿通孔７の軸芯Ｘ周りの方向、ネジ挿通孔７の軸芯Ｘに沿う方向にそれぞれ移動が許容される。In the waterproof sheet fixing state as described above, since the plate spring portion 6 can perform the functions of the connection mechanism J and the return mechanism R, the second member 4 can not perform the second operation with respect to the first member 4 fixed to the roof base 1.

また、屋根下地１に固定した第１部材４に対して、第２部材５が移動しても、両者の初期連結状態に戻すように復帰機構Ｒが作用し、第２部材５に固定されている防水シートも、屋根下地１上に設置した初期設置状態に戻すことができ、防水シート２全体として局部に圧縮力や引張力が残ったままになったり、シワがよったままになることを防止できるようになる。
その結果、風が吹いても、防水シート２を屋根下地１に確実な固定状態を維持した状態に固定でき、且つ、防水シート２の耐久性の低下を防止できるようになる。
また、シート固定具Ｋ１としての構造が簡単で、部品点数も少ないから、取扱性や経済性が良好で、且つ、第１部材４と第２部材５とが相対移動時に干渉し難いから、板バネ部６の特性を十分発揮させて上述の作用（連結機能や復帰機能）を叶える事ができる。Therefore, according to the sheet fixture K1 of the embodiment, for example, even when the waterproof sheet 2 is lifted by wind lift and waved, vibration or lateral movement force transmitted from the waterproof sheet 2 to the waterproof sheet fixture K1 And rotational force, lift, etc. can be buffered by the relative movement between the first member 4 and the second member 5, and the fixing screw member 3 can be loosened while the waterproof sheet 2 can be supported on the roof base 1 without difficulty. It can be prevented.
In addition, even if the second member 5 moves with respect to the first member 4 fixed to the roof foundation 1, the return mechanism R acts so as to return to the initial connection state of both members, and is fixed to the second member 5 The waterproof sheet can be returned to the initial installation condition installed on the roof foundation 1, and the entire area of the waterproof sheet 2 may remain compressive or tensile force locally, or may remain wrinkled. It can be prevented.
As a result, even when the wind blows, the waterproof sheet 2 can be fixed to the roof foundation 1 in a state of being securely fixed, and the decrease in the durability of the waterproof sheet 2 can be prevented.
In addition, since the structure as the sheet fixing tool K1 is simple and the number of parts is small, the handling property and the economy are good, and the first member 4 and the second member 5 are less likely to interfere with relative movement. The characteristics of the spring portion 6 can be sufficiently exhibited to provide the above-described functions (the connection function and the return function).
