Description

本発明は、止水性が求められ部位に用いる止水ねじに関する。 TECHNICAL FIELD The present invention relates to a water stop screw used in a site where water stop is required.

従来から止水性が求められ部位には、ねじの軸部に弾性ゴムよりなるワッシャを挿し込んで当該ねじを螺合することは知られている（たとえば、特許文献１参照）。このねじは、弾性ゴム製のワッシャをねじの軸部に挿し込みねじ頭部にモールドまたは接着する、或いは、ねじの締め付けの際に単品としての弾性ゴム製のワッシャをねじに装着することにより締め付け部からの水分の浸入を防止している。 Conventionally, it is known that a washer made of elastic rubber is inserted into the shank of a screw and the screw is screwed into a portion where water blocking is required (see, for example, Patent Document 1). This screw is tightened by inserting an elastic rubber washer into the shank of the screw and molding or adhering it to the screw head, or by attaching a separate elastic rubber washer to the screw when tightening the screw. It prevents the ingress of moisture from the part.

実開昭６０－１２２０１５号公報Japanese Utility Model Laid-Open No. 60-122015

上記のねじは、ねじ頭部の座面とねじが螺合される被螺合部材との間に介在される弾性ゴム製のワッシャにより締め付け部からの水分の浸入を防止しているので、ねじが締め込まれてねじ頭部とともに弾性ゴム製のワッシャを挟持する部材との間でしか水分の浸入を防止することができない。このため、例えば、被螺合部材に他の部材をねじで固定する場合などのように、ねじ頭部と被螺合部材との間に他の部材が介在される場合には、被螺合部材と他の部材との間などからねじの螺合部に水が浸入してしまう虞があり、止水性が低いという課題がある。
本発明は、かかる課題に鑑みてなされたものであり、その目的とするところは、より止水性に優れた止水ねじを提供することにある。 In the screw described above, an elastic rubber washer is interposed between the bearing surface of the screw head and the screwed member to which the screw is screwed to prevent moisture from entering from the tightening portion. Infiltration of moisture can only be prevented between the screw head and the member that clamps the elastic rubber washer together with the screw head. Therefore, when another member is interposed between the screw head and the member to be screwed, for example, when fixing another member to the member to be screwed with a screw, There is a risk that water will enter the threaded portion of the screw from between the member and another member, and there is a problem that the waterproofness is low.
SUMMARY OF THE INVENTION The present invention has been made in view of such problems, and an object of the present invention is to provide a water stop screw that is more excellent in water stoppage.

かかる目的を達成するための主たる発明は、ねじ頭部と、ねじ部と、前記ねじ頭部と前記ねじ部との間に設けられねじ山が形成されていない非ねじ部と、を有するねじ本体、及び、前記非ねじ部の周面を押圧しつつ挿通されている環状部材、を有することを特徴とする止水ねじである。
本発明の他の特徴については、本明細書及び添付図面の記載により明らかにする。 The main invention for achieving such an object is a screw body having a screw head, a threaded portion, and a non-threaded portion provided between the screw head and the threaded portion and having no thread formed thereon. and an annular member inserted while pressing against the peripheral surface of the non-threaded portion.
Other features of the present invention will become apparent from the description of the specification and accompanying drawings.

以下の説明においては、手摺り壁３の壁面に沿う方向を面内方向、壁面と直交する方向を面外方向として説明する。 The wooden part 30 forms the handrail wall 3 that partitions the inside and outside of the balcony, the outer peripheral surface is covered with a waterproof sheet 31, and the surface material 32 is provided on the inner surface side and the outer surface side of the balcony.
In the following description, the direction along the wall surface of the handrail wall 3 is defined as the in-plane direction, and the direction perpendicular to the wall surface is defined as the out-of-plane direction.

笠木１は、図２に示すように、手摺り壁３の長手方向に沿って手摺り壁３の全長にわたって設けられており、手摺り壁３の上方を覆う天面部１ａと、天面部１ａにおける面外方向における端部からほほ鉛直に繋がって手摺り壁３の上部における側面と対向する側面部１ｂと、を有している。笠木１の側面部１ｂの内面には、内側に向かって突出しホルダー２に係止される係止部１ｃが設けられている。 As shown in FIG. 2, the top rail 1 is provided over the entire length of the handrail wall 3 along the longitudinal direction of the handrail wall 3. It has a side surface portion 1b that is connected almost vertically from the end portion in the out-of-plane direction and faces the side surface of the upper portion of the handrail wall 3. As shown in FIG. On the inner surface of the side portion 1b of the coping 1, a locking portion 1c that protrudes inward and is locked to the holder 2 is provided.

ホルダー２は、手摺り壁３の面内方向に互いに適宜間隔を空けて複数設けられている。すなわち、ホルダー２は、手摺り壁３の長手方向における幅が手摺り壁３より十分に小さな部材である。 A plurality of holders 2 are provided at appropriate intervals in the in-plane direction of the handrail wall 3 . That is, the holder 2 is a member whose width in the longitudinal direction of the handrail wall 3 is sufficiently smaller than that of the handrail wall 3 .

ホルダー２は、木質部３０にねじ止めされる矩形状の天端固定部２ａと、天端固定部２ａの面外方向における両端部から上方に延出された２つの上方延出部２ｂと、２つの上方延出部２ｂの上端部から各々、面外方向においてバルコニーの内外方向に各々延出されて略水平な面を形成する水平面部２ｃと、水平面部２ｃから各々延出され先方側が低くなるように湾曲する延出腕部２ｄと、を有している。延出腕部２ｄは、先端が手摺り壁３の上方よりも外側に位置するように延出されており、その先端に笠木１の係止部１ｃが係止される。 The holder 2 includes a rectangular top end fixing portion 2a screwed to the wooden portion 30, two upwardly extending portions 2b extending upward from both ends of the top end fixing portion 2a in the out-of-plane direction, From the upper ends of the two upwardly extending portions 2b, the horizontal surface portion 2c extends in the inward and outward directions of the balcony in the out-of-plane direction to form a substantially horizontal surface, and the horizontal surface portion 2c extends from the horizontal surface portion 2c so that the front side is lower. and an extending arm portion 2d that is curved in such a manner. The extending arm portion 2d extends so that the tip thereof is positioned outside the upper portion of the handrail wall 3, and the engaging portion 1c of the top rail 1 is engaged with the tip thereof.

ホルダー２は、木質部３０の天端を覆う防水シート３１上に、止水ねじ４により固定されている。ホルダー２の天端固定部２ａには、止水ねじ４を挿通可能な４つの長穴２ｅが設けられており、本実施形態では、４つの長穴２ｅのうちの２つの長穴２ｅに止水ねじ４を挿通して固定している。ここで、ホルダー２が、貫通穴が設けられた第１部材に相当し、手摺り壁３が、止水ねじ４が螺合される第２部材に相当し、長穴２ｅが、第１部材に設けられた貫通穴に相当する。 The holder 2 is fixed by water stop screws 4 on a waterproof sheet 31 covering the top end of the wooden part 30 . The top end fixing portion 2a of the holder 2 is provided with four elongated holes 2e through which the water stop screws 4 can be inserted. A water screw 4 is inserted and fixed. Here, the holder 2 corresponds to the first member provided with a through hole, the handrail wall 3 corresponds to the second member to which the water stop screw 4 is screwed, and the long hole 2e corresponds to the first member. corresponds to a through hole provided in the

図１に示すように、長穴２ｅは、天端固定部２ａの四方に面外方向に沿って設けられており、対角に位置する２つの長穴２ｅに止水ねじ４が挿通される。本実施形態においては、貫通穴の内径は、長穴２ｅの短手方向の幅Ｗに相当する。ここで、止水ねじ４が挿通される穴は、長穴に限るものではない。 As shown in FIG. 1, the elongated holes 2e are provided along the out-of-plane direction on the four sides of the top end fixing portion 2a, and the water stop screws 4 are inserted through the two elongated holes 2e positioned diagonally. . In this embodiment, the inner diameter of the through hole corresponds to the width W of the elongated hole 2e in the lateral direction. Here, the hole through which the water stop screw 4 is inserted is not limited to the elongated hole.

止水ねじ４は、図３に示すように、ねじ頭部４ａと、ねじ部４ｂと、ねじ頭部４ａとねじ部４ｂとの間に設けられねじ山４ｃが形成されていない非ねじ部４ｄと、を有する、所謂半ねじでなるねじ本体４０、及び、非ねじ部４ｄの周面４ｅを押圧しつつ挿通されている環状部材４１、を有している。非ねじ部４ｄの直径Ｄ１は、ねじ部４ｂのねじ外径Ｄ２よりも僅かに大きく形成され、非ねじ部の長さＬ１は、天端固定部２ａの厚みｔ１よりも短く形成されている。また、ねじ頭部４ａの直径Ｄ３は、長穴２ｅの短手方向の幅Ｗよりも大きく形成されている。 As shown in FIG. 3, the water stop screw 4 includes a screw head 4a, a threaded portion 4b, and a non-threaded portion 4d provided between the screw head 4a and the threaded portion 4b and having no thread 4c. and an annular member 41 inserted while pressing against the peripheral surface 4e of the non-threaded portion 4d. The diameter D1 of the non-threaded portion 4d is formed slightly larger than the thread outer diameter D2 of the threaded portion 4b, and the length L1 of the non-threaded portion is formed shorter than the thickness t1 of the top fixing portion 2a. Further, the diameter D3 of the screw head 4a is formed to be larger than the width W of the elongated hole 2e in the lateral direction.

環状部材４１は、合成樹脂製の弾性部材、例えば、ポリ塩化ビニル製であり、ねじ外径Ｄ２よりも大きな外径Ｄ４のチューブ状をなしている。環状部材４１は、止水ねじ４が螺合される前の状態では、ねじ部４ｂと非ねじ部４ｄとに跨がるとともにねじ頭部の座面４ｆと間隔を空けて配置されている。また、環状部材４１は、非ねじ部４ｄの周面４ｅをねじ本体４０の軸側に押圧している。 The annular member 41 is an elastic member made of synthetic resin, such as polyvinyl chloride, and has a tubular shape with an outer diameter D4 larger than the screw outer diameter D2. Before the water stop screw 4 is screwed, the annular member 41 straddles the threaded portion 4b and the non-threaded portion 4d and is spaced apart from the bearing surface 4f of the screw head. Further, the annular member 41 presses the peripheral surface 4e of the non-threaded portion 4d toward the shaft of the screw body 40. As shown in FIG.

環状部材４１の外径Ｄ４は、長穴２ｅの短手方向の幅Ｗ（内径）よりも小さく形成されており、ねじ本体４０に挿通前の環状部材４１の内径は、非ねじ部４ｄの直径Ｄ１よりも僅かに小さく形成されている。このため、環状部材４１をねじ本体４０に挿通してねじ部４ｂと非ねじ部４ｄとに跨がるように配置すると、環状部材４１が非ねじ部４ｄの周面４ｅをねじ本体４０の軸側に押圧する。また、環状部材４１の長さＬ２は、天端固定部２ａの厚みｔ１よりも短く形成されている。 The outer diameter D4 of the annular member 41 is smaller than the width W (inner diameter) of the elongated hole 2e in the lateral direction. It is formed slightly smaller than D1. For this reason, when the annular member 41 is inserted into the screw body 40 and disposed so as to straddle the threaded portion 4b and the non-threaded portion 4d, the annular member 41 will move the peripheral surface 4e of the non-threaded portion 4d to the axis of the screw body 40. press to the side. Also, the length L2 of the annular member 41 is formed shorter than the thickness t1 of the top fixing portion 2a.

本実施形態の止水ねじ４を用いて笠木１の取り付け方法は、図４（ａ）に示すように、まず、防水シート３１に覆われた木質部３０に、ねじ外径Ｄ２に対応する下穴３０ａを形成しておく。 The method of attaching the coping 1 using the water shutoff screw 4 of this embodiment is as follows. First, as shown in FIG. 30a is formed.

次に、下穴３０ａと長穴２ｅとの位置を合わせてホルダー２を配置し、図４（ｂ）に示すように、長穴２ｅ、下穴３０ａに上方から止水ねじ４を挿入して木質部３０に螺合する。このとき、止水ねじ４を螺合していくと、環状部材４１が長穴２ｅ内に進入して、図４（ｃ）に示すように、下端部が防水シート３１に当接する。このとき、ねじ頭部４ａの座面４ｆは、天端固定部２ａに当接していない。 Next, the holder 2 is placed by aligning the pilot hole 30a and the elongated hole 2e, and as shown in FIG. It is screwed onto the wood portion 30 . At this time, as the water shutoff screw 4 is screwed together, the annular member 41 enters the long hole 2e, and the lower end abuts against the waterproof sheet 31 as shown in FIG. 4(c). At this time, the bearing surface 4f of the screw head 4a is not in contact with the top fixing portion 2a.

そして、更に止水ねじ４を螺合して締め込むと、環状部材４１は、防水シート３１に覆われた木質部３０により移動が規制され、ねじ本体４０のみが木質部３０に進入し、図４（ｄ）に示すように、ねじ頭部４ａの座面４ｆが天端固定部２ａに当接し、ホルダー２が防水シート３１に覆われた木質部３０に固定される。このとき、環状部材４１は、非ねじ部４ｄを押圧しつつねじ本体４０に対して相対移動するので、環状部材４１と非ねじ部４ｄとの間に摩擦が生じ、環状部材４１は、止水ねじ４が螺合されているねじ螺合部を囲むように防水シート３１に当接されて、防水シート３１及び木質部３０を下方に押圧する。 When the water stop screw 4 is further screwed and tightened, the movement of the annular member 41 is restricted by the wooden portion 30 covered with the waterproof sheet 31, and only the screw main body 40 enters the wooden portion 30, as shown in FIG. As shown in d), the bearing surface 4f of the screw head 4a comes into contact with the top fixing portion 2a, and the holder 2 is fixed to the wooden portion 30 covered with the waterproof sheet 31. As shown in FIG. At this time, since the annular member 41 moves relative to the screw body 40 while pressing the non-threaded portion 4d, friction is generated between the annular member 41 and the non-threaded portion 4d, and the annular member 41 acts as a water stop. It abuts against the waterproof sheet 31 so as to surround the threaded portion to which the screw 4 is screwed, and presses the waterproof sheet 31 and the wooden portion 30 downward.

次に、手摺り壁３及びホルダー２の上方から笠木１を被せ、笠木１をホルダー２に係止して、笠木１を手摺り壁３に取り付ける。 Next, the top rail 1 is put on the handrail wall 3 and the holder 2 from above, the top rail 1 is locked to the holder 2, and the top rail 1 is attached to the handrail wall 3. - 特許庁

本実施形態の止水ねじ４によれば、止水ねじ４を締めるに連れて、非ねじ部４ｄの周面４ｅを押圧しつつ挿通されている環状部材４１が、ねじ部４ｂが螺合される木質部３０を覆う防水シート３１に近接し、更に止水ねじ４を締め込むことにより環状部材４１は防水シート３１に当接されるとともに防水シート３１及び木質部３０によりねじ本体４０とともに移動することが規制される。そして、止水ねじ４を締め込むことにより環状部材４１は、防水シート３１及び木質部３０を押圧しつつねじ頭部４ａ側に相対的に移動する。 According to the water stop screw 4 of this embodiment, as the water stop screw 4 is tightened, the annular member 41 inserted while pressing against the peripheral surface 4e of the non-threaded portion 4d is screwed into the threaded portion 4b. By approaching the waterproof sheet 31 covering the wooden portion 30 and further tightening the water stop screw 4, the annular member 41 is brought into contact with the waterproof sheet 31 and can be moved together with the screw main body 40 by the waterproof sheet 31 and the wooden portion 30. Regulated. By tightening the water stop screw 4, the annular member 41 presses against the waterproof sheet 31 and the wooden portion 30 and relatively moves toward the screw head 4a.

止水ねじ４が締め込まれた状態では、環状部材４１は、非ねじ部４ｄの周面４ｅを押圧するとともに螺合されているねじ部４ｂの周りにて防水シート３１及び木質部３０を押圧している。このため、ねじ螺合部への水の浸入をより確実に防止することが可能である。このため、より止水性に優れた止水ねじ４を提供することが可能である。 When the water stop screw 4 is tightened, the annular member 41 presses the peripheral surface 4e of the non-threaded portion 4d and presses the waterproof sheet 31 and the wooden portion 30 around the threaded portion 4b. ing. Therefore, it is possible to more reliably prevent water from entering the threaded portion. For this reason, it is possible to provide a water stop screw 4 having more excellent water stop properties.

また、環状部材４１が、ねじ頭部４ａと間隔を空けて配置されているので、環状部材４１が防水シート３１に当接された後に止水ねじ４が締められると、環状部材４１は、非ねじ部４ｄの周面４ｅを押圧しつつ確実にねじ頭部４ａ側に相対移動する。このため、止水ねじ４の螺合部を止水しつつもより確実に止水ねじ４を締め込むことが可能である。 Further, since the annular member 41 is spaced apart from the screw head 4a, when the water stop screw 4 is tightened after the annular member 41 is brought into contact with the waterproof sheet 31, the annular member 41 is While pressing the peripheral surface 4e of the screw portion 4d, the screw head 4a is reliably moved relative to the screw head portion 4a. Therefore, it is possible to more securely tighten the water stop screw 4 while water is stopped at the threaded portion of the water stop screw 4 .

また、非ねじ部４ｄがねじ外径Ｄ２よりも大きな直径Ｄ１をなしているので、環状部材４１を、ねじ部４ｂを挿通させて配置したとしても非ねじ部４ｄの周面４ｅをより確実に押圧することができ、また、防水シート３１に覆われた木質部３０において、螺合されているねじ部４ｂの外側にて環状部材４１を防水シート３１に押圧させることができる。このため、螺合部をより確実に止水することが可能である。 Further, since the non-threaded portion 4d has a diameter D1 larger than the thread outer diameter D2, even if the annular member 41 is arranged so as to pass through the threaded portion 4b, the peripheral surface 4e of the non-threaded portion 4d can be more reliably secured. In addition, in the wooden portion 30 covered with the waterproof sheet 31, the annular member 41 can be pressed against the waterproof sheet 31 outside the threaded portion 4b. Therefore, it is possible to more reliably stop water from the threaded portion.

また、環状部材４１の外径Ｄ４がねじ外径Ｄ２よりも大きいので、止水ねじ４を締め込んだ際には、螺合された止水ねじ４により防水シート３１に形成された切れ目の外側で環状部材４１を防水シート３１に押圧させることができる。このため、螺合部をより確実に止水することが可能である。 In addition, since the outer diameter D4 of the annular member 41 is larger than the screw outer diameter D2, when the water stop screw 4 is tightened, the screwed water stop screw 4 causes a break outside the waterproof sheet 31 to be formed. , the annular member 41 can be pressed against the waterproof sheet 31 . Therefore, it is possible to more reliably stop water from the threaded portion.

また、環状部材４１の外径Ｄ４は、長穴２ｅの短手方向の幅Ｗよりも小さいので、防水シート３１に覆われた木質部３０に止水ねじ４が螺合されると、止水ねじ４に挿通されている環状部材４１は、長穴２ｅ内に進入し、環状部材４１が防水シート３１に押圧され、ねじ頭部４ａが長穴２ｅを覆うように天端固定部２ａに当接して止水ねじ４が締め込まれる。このため、環状部材４１により、止水ねじ４が螺合されている木質部３０側には水が浸入しないので、ねじ頭部４ａと天端固定部２ａとの間にて止水する場合のように、天端固定部２ａと防水シート３１の間からの水の浸入も防止することが可能である。このため、止水ねじ４の螺合部をより確実に止水することが可能である。 Further, since the outer diameter D4 of the annular member 41 is smaller than the width W of the elongated hole 2e in the lateral direction, when the water stop screw 4 is screwed into the wooden portion 30 covered with the waterproof sheet 31, the water stop screw 4, the annular member 41 is inserted into the long hole 2e, the annular member 41 is pressed against the waterproof sheet 31, and the screw head 4a comes into contact with the top end fixing portion 2a so as to cover the long hole 2e. Then, the water stop screw 4 is tightened. For this reason, the annular member 41 prevents water from entering the wooden portion 30 side to which the water stop screw 4 is screwed. In addition, it is possible to prevent water from entering between the top fixing portion 2a and the waterproof sheet 31. Therefore, it is possible to more reliably stop water at the threaded portion of the water stop screw 4 .

また、環状部材４１がポリ塩化ビニル製なので、非ねじ部４ｄの周面４ｅをより確実に押圧することが可能である。このため、より高い止水性を備えることが可能である。 Further, since the annular member 41 is made of polyvinyl chloride, it is possible to press the peripheral surface 4e of the non-threaded portion 4d more reliably. For this reason, it is possible to provide higher water stoppage.

上記実施形態においては、環状部材４１をポリ塩化ビニル製としたが、これに限らず、例えば、非ねじ部の周面を押圧しつつ挿通可能な材料であれば構わない。
上記実施形態においては、止水ねじ４を締め込むことにより環状部材４１が防水シート３１及び木質部３０を押圧しつつねじ頭部４ａ側に相対的に移動する例について説明したが、これに限らず、例えば、止水ねじ４を締め込んだ際に、環状部材４１が防水シート３１とねじ頭部４ａとの間にて圧縮されることにより止水ねじ４の螺合部が止水される懈怠であっても構わない。 In the above embodiment, the annular member 41 is made of polyvinyl chloride, but it is not limited to this, and any material that can be inserted while pressing the peripheral surface of the non-threaded portion may be used.
In the above embodiment, an example was described in which the annular member 41 presses against the waterproof sheet 31 and the wooden portion 30 and relatively moves toward the screw head 4a by tightening the water stop screw 4. However, the present invention is not limited to this. For example, when the water stop screw 4 is tightened, the annular member 41 is compressed between the waterproof sheet 31 and the screw head 4a, so that the threaded portion of the water stop screw 4 is water-stopped. It doesn't matter if it is.

上記実施形態においては、手摺り壁３が有する木質部３０へのホルダー２の固定に本発明の止水ねじ４を用いた例について説明したが、これに限るものではない。すなわち、止水ねじが螺合される木質部は、手摺り壁に限らず、また、止水ねじにより固定される部材はホルダーに限るものではなく、止水ねじが螺合される部材側への水の浸入を防ぎつつ止水ねじを螺合する部位であれば、いずれの部位であっても適用可能である。このため、何らかの部材を固定する場合ばかりでなく、ばねやワイヤーなどの部材を引っ掛けるためなど、ねじ頭部の座面が、他の部材と間隔を空けた状態で止水ねじが設けられる場合にも適用可能である。 In the above embodiment, an example was described in which the water stop screw 4 of the present invention was used to fix the holder 2 to the wooden portion 30 of the handrail wall 3, but the present invention is not limited to this. That is, the wooden part to which the water stop screw is screwed is not limited to the handrail wall, and the member fixed by the water stop screw is not limited to the holder. Any part can be applied as long as it is a part where a water stop screw can be screwed together while preventing water from entering. For this reason, not only when fixing some member, but also when a water stop screw is provided with a gap between the bearing surface of the screw head and other members, such as for hooking a member such as a spring or wire. is also applicable.

上記実施形態は、本発明の理解を容易にするためのものであり、本発明を限定して解釈するためのものではない。本発明は、その趣旨を逸脱することなく、変更、改良され得ると共に、本発明にはその等価物が含まれることはいうまでもない。 The above-described embodiments are intended to facilitate understanding of the present invention, and are not intended to limit and interpret the present invention. The present invention can be modified and improved without departing from its spirit, and it goes without saying that the present invention includes equivalents thereof.

本実施形態には、少なくとも以下の発明が含まれる。
ねじ頭部と、ねじ部と、前記ねじ頭部と前記ねじ部との間に設けられねじ山が形成されていない非ねじ部と、を有するねじ本体、及び、前記非ねじ部の周面を押圧しつつ挿通されている環状部材と、を有することを特徴とする止水ねじである。 This embodiment includes at least the following inventions.

このような止水ねじによれば、止水ねじを締めるに連れて、非ねじ部の周面を押圧しつつ挿通されている環状部材が、ねじ部が螺合される被螺合部材に近接し、更に止水ねじを締め込むことにより環状部材が被螺合部材に当接されるとともに被螺合部材によりねじ本体とともに移動することが規制される。そして、止水ねじを締め込むことにより環状部材は、被螺合部材を押圧しつつねじ頭部側に相対的に移動する。このとき、止水ねじが締め込まれた状態では、環状部材は、非ねじ部の周面を押圧するとともに被螺合部材に螺合されているねじ部の周りにて被螺合部材を押圧している。このため、ねじ螺合部への水の浸入をより確実に防止することが可能である。このため、より止水性に優れた止水ねじを提供することが可能である。 According to such a water stop screw, as the water stop screw is tightened, the annular member inserted while pressing the peripheral surface of the non-threaded portion approaches the threaded member to which the threaded portion is screwed. Further, by tightening the water stop screw, the annular member is brought into contact with the member to be screwed, and the member to be screwed restricts movement together with the screw body. By tightening the water stop screw, the annular member presses the member to be screwed and relatively moves toward the screw head side. At this time, when the water stop screw is tightened, the annular member presses the peripheral surface of the non-threaded portion and presses the screwed member around the threaded portion screwed to the screwed member. are doing. Therefore, it is possible to more reliably prevent water from entering the threaded portion. For this reason, it is possible to provide a water stop screw with more excellent water stop properties.

かかる止水ねじであって、前記環状部材は、前記ねじ頭部と間隔を空けて配置されていることを特徴とする。
このような止水ねじによれば、環状部材が、ねじ頭部と間隔を空けて配置されているので、環状部材が被螺合部材に当接された後に止水ねじが締められると、環状部材は、非ねじ部の周面を押圧しつつ確実にねじ頭部側に移動する。このため、止水ねじの螺合部を止水しつつもより確実に止水ねじを締め込むことが可能である。 This water stop screw is characterized in that the annular member is spaced apart from the screw head.
According to such a water stop screw, the annular member is spaced apart from the screw head. The member reliably moves toward the screw head while pressing against the peripheral surface of the non-threaded portion. Therefore, it is possible to more reliably tighten the water stop screw while water is stopped at the threaded portion of the water stop screw.

かかる止水ねじであって、前記環状部材の外径は、当該止水ねじのねじ外径よりも大きいことを特徴とする。
このような止水ねじによれば、環状部材の外径がねじ外径よりも大きいので、止水ねじを締め込んだ際には、螺合された止水ねじにより被螺合部材に形成された切れ目の外側で環状部材を被螺合部材に押圧させることができる。このため、螺合部をより確実に止水することが可能である。 This water stop screw is characterized in that the outer diameter of the annular member is larger than the thread outer diameter of the water stop screw.
According to such a water stop screw, since the outer diameter of the annular member is larger than the outer diameter of the screw, when the water stop screw is tightened, the threaded water stop screw forms the The annular member can be pressed against the member to be screwed on the outside of the cut. Therefore, it is possible to more reliably stop water from the threaded portion.

かかる止水ねじであって、第１部材に設けられた貫通穴を貫通し第２部材に螺合されて前記第１部材を前記第２部材に固定し、前記ねじ頭部の直径は、前記貫通穴の内径よりも大きく、前記環状部材の外径は、前記貫通穴の内径よりも小さいことを特徴とする。 In such a water stop screw, the first member is passed through a through hole provided in the first member and screwed into the second member to fix the first member to the second member, and the diameter of the screw head is It is characterized in that the outer diameter of the annular member is larger than the inner diameter of the through hole, and the outer diameter of the annular member is smaller than the inner diameter of the through hole.

このような止水ねじによれば、環状部材の外径は、貫通穴の内径よりも小さいので、被螺合部材をなす第２部材に止水ねじが螺合されると、止水ねじに挿通されている環状部材は、貫通穴内に進入し、環状部材が第２部材に押圧されてねじ頭部が貫通穴を覆うように第１部材に当接して止水ねじが締め込まれる。このため、環状部材により、止水ねじが螺合されている第２部材側には水が浸入しないので、ねじ頭部と第１部材との間にて止水する場合のように、第１部材と第２部材の間からの水の浸入も防止することが可能である。このため、止水ねじの螺合部をより確実に止水することが可能である。 According to such a water stop screw, since the outer diameter of the annular member is smaller than the inner diameter of the through hole, when the water stop screw is screwed into the second member forming the threaded member, the water stop screw The inserted annular member enters the through hole, and the annular member is pressed by the second member to abut against the first member so that the screw head covers the through hole, and the water stop screw is tightened. Therefore, the annular member prevents water from entering the side of the second member to which the water stop screw is screwed. Intrusion of water from between the member and the second member can also be prevented. Therefore, it is possible to more reliably stop water at the threaded portion of the water stop screw.

かかる止水ねじであって、前記環状部材は、合成樹脂製の弾性部材であることを特徴とする。
このような止水ねじによれば、環状部材が合成樹脂製の弾性部材なので、非ねじ部の周面をより確実に押圧することが可能である。このため、より高い止水性を備えることが可能である。 This water stop screw is characterized in that the annular member is an elastic member made of synthetic resin.
According to such a water stop screw, since the annular member is an elastic member made of synthetic resin, it is possible to press the peripheral surface of the non-threaded portion more reliably. For this reason, it is possible to provide higher water stoppage.
