Description
本発明は、２つの部材の接合構造に関する。 The present invention relates to a joining structure of two members.
２つの部材の接合構造としては、例えば、軒樋と、当該軒樋の両端部に設けられている排水孔のうちの一方を塞ぐ止水キャップと、を接合する接合構造が知られている(例えば、特許文献１参照)。この接合構造は、軒樋に設けられている排水孔を覆う大きさの板状の止水キャップが、軟質の合成樹脂で形成された止水シートが軒樋との間に介在されて軒樋に取り付けられている。止水キャップと止水シートとには、各々軒樋に螺合されるねじが挿通される挿通孔が設けられている。 As a joining structure of two members, for example, a joining structure that joins an eave ridge and a water stop cap that closes one of drain holes provided at both ends of the eave ridge is known ( For example, see Patent Document 1). In this joint structure, a plate-shaped water stop cap of a size covering the drainage hole provided in the eaves eaves, and a water stop sheet formed of a soft synthetic resin is interposed between the eave eaves. Is attached. The water stop cap and the water stop sheet are provided with insertion holes through which screws to be screwed into the eaves are inserted.
そして、止水シートが重ねられた止水キャップを、軒樋の排水孔を覆うように配置し、止水キャップ側から進入するねじを、挿通孔を挿通させて軒樋に螺合している。軒樋に螺合されたねじが貫通しているねじ孔の周囲には湿式のシーリング材が施されているものもある。 And the water stop cap with which the water stop sheet was piled up is arranged so as to cover the drainage hole of the eaves bowl, and the screw entering from the water stop cap side is inserted through the insertion hole and screwed into the eave bowl. . In some cases, a wet sealant is provided around a screw hole through which a screw screwed into the eaves passes.
上記接合構造では、軒樋との間に止水シートを介在させて止水キャップ側から進入するねじを軒樋に螺合しているので、ねじの締め付けにより止水シートが圧縮される。このとき、止水シートが弾性変形しない状態まで押し潰されてしまっていると、経年の変化等により隙間が生じ易く、漏水する虞がある。また、ねじ締め込み量及びシーリング材の施し方は、作業者の技量等により差があるため、十分な止水性能が得られない虞があるという課題がある。 In the joining structure, since the water-stopping sheet is interposed between the eaves and the screw entering from the water-stopping cap side is screwed into the eaves, the water-stopping sheet is compressed by tightening the screws. At this time, if the water-stop sheet is crushed to a state where it does not elastically deform, a gap is likely to occur due to a change over time, and water may leak. Moreover, since there is a difference in the amount of screw tightening and how to apply the sealing material depending on the skill of the operator, there is a problem that sufficient water stop performance may not be obtained.
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、簡単な作業により高い止水性能を備えて接合できる接合構造を提供することにある。 This invention is made | formed in view of this subject, The place made into the objective is to provide the junction structure which can be joined with high water stop performance by simple operation | work.
かかる目的を達成するために本発明の接合構造は、第１部材に設けられた挿通孔に挿通されたねじを第２部材に螺合して接合する２つの部材の接合構造であって、前記第１部材と前記第２部材との間にはシール部材が介在されており、前記シール部材は、前記挿通孔内に挿通され、前記第１部材において前記第２部材と対向する対向面とは反対側の反対向面よりも突出する筒状部を有し、前記第１部材は、前記反対向面から突出し、前記挿通孔よりも大きな内径をなして当該挿通孔を囲む環状突出部を有し、前記ねじは、前記第２部材に螺合されて頭部が前記環状突出部に当接されており、前記筒状部は、前記環状突出部の内側にて前記第１部材と前記ねじの前記頭部とにより圧縮されていることを特徴とする接合構造である。 In order to achieve such an object, the joining structure of the present invention is a joining structure of two members for screwing and joining a screw inserted through an insertion hole provided in a first member to a second member, A seal member is interposed between the first member and the second member, the seal member is inserted into the insertion hole, and a facing surface of the first member facing the second member is The first member has an annular protrusion that protrudes from the opposite surface and has an inner diameter larger than the insertion hole and surrounds the insertion hole. The screw is screwed into the second member and a head is in contact with the annular projecting portion, and the cylindrical portion is connected to the first member and the screw inside the annular projecting portion. The joint structure is compressed by the head.
このような接合構造によれば、第１部材の挿通孔に挿通されたねじが第２部材に螺合されると、ねじの頭部が、第１部材の反対向面から突出している環状突出部に当接される。このため、作業者に拘わらずねじは一定量締め込まれるので、作業者による仕上がり状態のばらつきを抑制することが可能である。また、ねじの頭部と第１部材の反対向面との間には所定の間隔の空間が形成されるので、ねじを締め込むだけの簡単な作業により、第１部材とねじの頭部とにより筒状部を一定量圧縮することが可能である。 According to such a joining structure, when the screw inserted through the insertion hole of the first member is screwed into the second member, the head of the screw protrudes from the opposite surface of the first member. Abutted against the part. For this reason, since the screw is tightened by a certain amount regardless of the operator, it is possible to suppress variations in the finished state by the operator. In addition, since a space having a predetermined interval is formed between the head of the screw and the opposite surface of the first member, the first member and the head of the screw can be easily operated by simply tightening the screw. Thus, it is possible to compress the cylindrical portion by a certain amount.
また、第１部材の反対向面よりも突出している筒状部が第１部材とねじの頭部との間にて圧縮されているので、第２部材に螺合されて当該第２部材から突出しているねじの周囲にシーリングを施さなくとも高い止水性能を備えることが可能である。このため、シーリングを施さないので、作業者の技量に委ねられることなく高い止水性能を備えて接合することが可能である。また、筒状部は環状突出部の内側で圧縮されるので、外部に露出しない。このため、美観に優れた接合構造を実現することが可能である。 Moreover, since the cylindrical part which protrudes rather than the opposite surface of a 1st member is compressed between the 1st member and the head part of a screw, it is screwed together by the 2nd member and from the said 2nd member It is possible to provide a high water stop performance without sealing around the protruding screw. For this reason, since sealing is not performed, it is possible to join with high water stop performance without being left to the skill of the operator. Further, since the cylindrical portion is compressed inside the annular protrusion, it is not exposed to the outside. For this reason, it is possible to implement | achieve the junction structure excellent in aesthetics.

本実施形態の接合構造は、第１部材としてのカバー部材３の、第２部材としての軒樋部材１への接合部に用いられている。カバー部材３は、軒樋部材１との間に、可撓性を有し弾性変形可能な合成樹製のシール部材６（図３、図４）を介して軒樋部材１に取り付けられている。 The joining structure of the present embodiment is used in a joining portion of the cover member 3 as the first member to the eaves member 1 as the second member. The cover member 3 is attached to the eaves ridge member 1 via a synthetic resin seal member 6 (FIGS. 3 and 4) that is flexible and elastically deformable between the cover member 3 and the eaves ridge member 1. .
軒樋部材１は、押出成形部材であり、図３に示すように、軒樋部材１の樋部１０の底板部１０ｂに左右方向に長い楕円形状の排水孔１０ａが左右方向の端部側に設けられている。排水孔１０ａの左右には、カバー部材３または連結部材５を固定する為のねじ７が螺合されるねじ螺合孔１０ｃがそれぞれ設けられている。本実施形態においては、ねじ７として頭部７ａの高さが低く頭部７ａの外径Ｄ１が大きなトラスねじを用いている。 The eaves member 1 is an extrusion-molded member. As shown in FIG. 3, an elongate drainage hole 10a elongated in the left-right direction is formed on the bottom plate portion 10b of the eaves portion 10 of the eaves member 1 on the end side in the left-right direction. Is provided. Screw screw holes 10c into which screws 7 for fixing the cover member 3 or the connecting member 5 are screwed are provided on the left and right sides of the drain hole 10a. In the present embodiment, a truss screw having a low head 7a and a large outer diameter D1 is used as the screw 7.
図４、図５に示すように、カバー部材３は、長方形状のほぼ平板状をなし、長手方向の両端部側にねじ７が挿通される挿通孔３ａが設けられている。また、軒樋部材１に取り付けられたときに、カバー部材３の軒樋部材１の底板部１０ｂと対向する対向面３ｂには、外周部に沿って僅かに突出する外周突起３ｃと、排水孔１０ａと対向する部位より僅かに大きく排水孔１０ａの輪郭に沿うように突出された楕円突起３ｄと、楕円突起３ｄの左右の両側であって外周突起３ｃとの間に設けられ挿通孔３ａと同心に形成された円弧突起３ｅと、を有している。外周突起３ｃ、楕円突起３ｄ及び円弧突起３ｅの対向面３ｂからの突出量は同一である。 As shown in FIGS. 4 and 5, the cover member 3 has a substantially flat rectangular shape, and is provided with insertion holes 3 a through which screws 7 are inserted at both ends in the longitudinal direction. Further, when attached to the eaves member 1, an opposing surface 3b of the cover member 3 that faces the bottom plate portion 10b of the eaves member 1 has an outer peripheral projection 3c that slightly protrudes along the outer peripheral portion, and a drain hole. The elliptical projection 3d that is slightly larger than the portion facing the 10a and protrudes along the contour of the drainage hole 10a and the outer circumferential projection 3c on both the left and right sides of the elliptical projection 3d are concentric with the insertion hole 3a. And arcuate protrusion 3e formed. The protrusion amounts of the outer peripheral protrusion 3c, the elliptical protrusion 3d and the arc protrusion 3e from the facing surface 3b are the same.
また、カバー部材３において対向面３ｂとは反対側の反対向面３ｆには、挿通孔３ａと同心に形成され、軒樋部材１とは反対側に突出する環状突出部３ｇが設けられている。環状突出部３ｇの内径Ｄ２は、ねじ７の頭部７ａの外径Ｄ１より小さく形成されている。そして、カバー部材３側から進入させたねじ７を軒樋部材１に螺合すると、ねじ７の頭部７ａの外周縁部が環状突出部３ｇに当接され、環状突出部３ｇの内側にてカバー部材３とねじ７の頭部７ａとの間に空間Ｓが形成される。 The cover member 3 is provided with an annular projecting portion 3g formed concentrically with the insertion hole 3a and projecting on the side opposite to the eaves-eating member 1 on the opposite surface 3f opposite to the facing surface 3b. . An inner diameter D2 of the annular protrusion 3g is formed smaller than an outer diameter D1 of the head 7a of the screw 7. When the screw 7 entered from the cover member 3 side is screwed into the eaves member 1, the outer peripheral edge portion of the head 7a of the screw 7 is brought into contact with the annular projecting portion 3g, and inside the annular projecting portion 3g. A space S is formed between the cover member 3 and the head 7 a of the screw 7.
本実施形態のシール部材６は、カバー部材３と一体成形されている。シール部材６は、カバー部材３の対向面３ｂに設けられた外周突起３ｃの内側に全周に亘って設けられている外周止水部６ａと、楕円突起３ｄの外側に楕円突起３ｄに沿って設けられている楕円止水部６ｂと、外周止水部６ａと楕円止水部６ｂとの間にて円弧突起３ｅの内側に設けられた円形止水部６ｃと、を有している。外周止水部６ａ、楕円止水部６ｂ及び円形止水部６ｃは一体に繋がっており、外周突起３ｃ、楕円突起３ｄ及び円弧突起３ｅよりも大きく突出している。外周止水部６ａ、楕円止水部６ｂ及び円形止水部６ｃの突出量は同一である。 The seal member 6 of this embodiment is formed integrally with the cover member 3. The seal member 6 includes an outer peripheral water stop portion 6a provided over the entire circumference on the inner side of the outer peripheral projection 3c provided on the facing surface 3b of the cover member 3, and an outer side of the elliptical projection 3d along the elliptical projection 3d. It has an elliptical waterstop 6b provided, and a circular waterstop 6c provided inside the arc projection 3e between the outer peripheral waterstop 6a and the elliptical waterstop 6b. The outer peripheral water stop portion 6a, the elliptical water stop portion 6b, and the circular water stop portion 6c are connected together and protrude larger than the outer peripheral protrusion 3c, the elliptic protrusion 3d, and the arc protrusion 3e. The protrusion amount of the outer periphery water stop part 6a, the elliptical water stop part 6b, and the circular water stop part 6c is the same.
円形止水部６ｃは、図５に示すように、カバー部材３に設けられている挿通孔３ａからカバー部材３の反対側に突出し、カバー部材３の厚み方向に貫通する貫通孔６ｄを備えた筒状部６ｅを有している。カバー部材３と一体成形されたシール部材６の筒状部６ｅの外周面はカバー部材３の挿通孔３ａと繋がっている。 As shown in FIG. 5, the circular water blocking portion 6 c includes a through hole 6 d that protrudes from the insertion hole 3 a provided in the cover member 3 to the opposite side of the cover member 3 and penetrates in the thickness direction of the cover member 3. It has a cylindrical portion 6e. The outer peripheral surface of the cylindrical portion 6 e of the seal member 6 formed integrally with the cover member 3 is connected to the insertion hole 3 a of the cover member 3.
筒状部６ｅは、カバー部材３に設けられた環状突出部３ｇよりも大きく突出している。筒状部６ｅの反対向面３ｆからの突出量Ｌ１は、環状突出部３ｇと挿通孔３ａとの直径方向の間隔Ｗより小さい。また、筒状部６ｅの肉厚ｔは、環状突出部３ｇの反対向面３ｆからの突出量Ｌ２より厚く形成されている。さらに、ねじ７が軒樋部材１に螺合されて環状突出部３ｇの内側に形成され、カバー部材３と頭部７ａとの間の空間Ｓの容積が、環状突出部３ｇのカバー部材３よりも突出している部位６ｆの体積より大きくなるように構成されている。 The cylindrical portion 6 e protrudes larger than the annular protrusion 3 g provided on the cover member 3. The protruding amount L1 of the cylindrical portion 6e from the opposite surface 3f is smaller than the radial interval W between the annular protruding portion 3g and the insertion hole 3a. Further, the thickness t of the cylindrical portion 6e is formed to be thicker than the protruding amount L2 from the opposite surface 3f of the annular protruding portion 3g. Furthermore, the screw 7 is screwed to the eaves member 1 to be formed inside the annular protrusion 3g, and the volume of the space S between the cover member 3 and the head 7a is larger than that of the cover member 3 of the annular protrusion 3g. Is also configured to be larger than the volume of the protruding portion 6f.
シール部材６と一体となったカバー部材３を軒樋部材１に取り付ける場合には、まず、カバー部材３のシール部材６側を軒樋部材１の底板部１０ｂの下面に当接させる。このとき、軒樋部材１の２つのねじ螺合孔１０ｃとシール部材６の２つの貫通孔６ｄとの位置を合わせると、軒樋部材１の排水孔１０ａがシール部材６の楕円止水部６ｂの内側に配置される。 When the cover member 3 integrated with the seal member 6 is attached to the eaves member 1, first, the seal member 6 side of the cover member 3 is brought into contact with the lower surface of the bottom plate portion 10 b of the eaves member 1. At this time, when the positions of the two screw screw holes 10 c of the eaves member 1 and the two through holes 6 d of the seal member 6 are aligned, the drain hole 10 a of the eaves member 1 becomes the elliptical water stop 6 b of the seal member 6. Placed inside.
次に、貫通孔６ｄに挿通させたねじ７をねじ螺合孔１０ｃに螺合してカバー部材３及びシール部材６を軒樋部材１に取り付ける。このとき、ねじ７の頭部７ａを、環状突出部３ｇに当接させると、外周止水部６ａ、楕円止水部６ｂ及び円形止水部６ｃが圧縮されると共に、シール部材６の筒状部６ｅのカバー部材３より突出している部位６ｆが、環状突出部３ｇの内側にてカバー部材３とねじ７の頭部７ａとの間で圧縮される。 Next, the screw 7 inserted through the through hole 6 d is screwed into the screw screw hole 10 c to attach the cover member 3 and the seal member 6 to the eaves member 1. At this time, when the head portion 7a of the screw 7 is brought into contact with the annular projecting portion 3g, the outer peripheral water stop portion 6a, the elliptical water stop portion 6b and the circular water stop portion 6c are compressed, and the cylindrical shape of the seal member 6 A portion 6f of the portion 6e protruding from the cover member 3 is compressed between the cover member 3 and the head 7a of the screw 7 inside the annular protruding portion 3g.
本実施形態の接合構造によれば、カバー部材３の挿通孔３ａに挿通されたねじ７が軒樋部材１に螺合されると、ねじ７の頭部７ａが、カバー部材３の反対向面３ｆから突出している環状突出部３ｇに当接される。このため、作業者に委ねられることなく、ねじ７は一定量締め込まれるので、作業者による仕上がり状態のばらつきを抑制することが可能である。このとき、ねじ７の頭部７ａとカバー部材３の反対向面３ｆとの間には所定の空間Ｓが形成されるので、ねじ７を締め込むだけの簡単な作業により、カバー部材３とねじ７の頭部７ａとにより筒状部６ｅを一定量圧縮することが可能である。 According to the joining structure of the present embodiment, when the screw 7 inserted into the insertion hole 3 a of the cover member 3 is screwed into the eaves member 1, the head portion 7 a of the screw 7 is the opposite surface of the cover member 3. It abuts on the annular protrusion 3g protruding from 3f. For this reason, since the screw 7 is tightened by a certain amount without being left to the operator, it is possible to suppress variations in the finished state by the operator. At this time, since a predetermined space S is formed between the head 7 a of the screw 7 and the opposite surface 3 f of the cover member 3, the cover member 3 and the screw can be screwed by a simple operation of tightening the screw 7. The cylindrical portion 6e can be compressed by a certain amount by the seven heads 7a.
また、カバー部材３の反対向面３ｆよりも突出している筒状部６ｅがカバー部材３とねじ７の頭部７ａとの間にて圧縮されるので、例えば、軒樋部材１に螺合されて当該カバー部材３から突出しているねじ７の周囲にシーリングを施さなくとも高い止水性能を備えることが可能である。このため、シーリングを施さないので、作業者の技量に拘わることなく高い止水性能を備えることが可能である。また、筒状部６ｅは環状突出部３ｇの内側で圧縮されるので、外部に露出しない。このため、美観に優れた接合構造を実現することが可能である。 Moreover, since the cylindrical part 6e which protrudes rather than the counter-facing surface 3f of the cover member 3 is compressed between the cover member 3 and the head part 7a of the screw 7, it is screwed to the eaves member 1 for example. Therefore, it is possible to provide a high water-stopping performance without sealing around the screw 7 protruding from the cover member 3. For this reason, since sealing is not performed, it is possible to provide high water stopping performance without regard to the skill of the operator. Moreover, since the cylindrical part 6e is compressed inside the annular protrusion part 3g, it is not exposed outside. For this reason, it is possible to implement | achieve the junction structure excellent in aesthetics.
また、環状突出部３ｇの内径Ｄ２は、ねじ７の頭部７ａの外径Ｄ１より小さいので、環状突出部３ｇの内側をねじ７の頭部７ａにより覆うことができる。このため、圧縮された筒状部６ｅが外部に露出することをより確実に防止することが可能である。 Further, since the inner diameter D2 of the annular protrusion 3g is smaller than the outer diameter D1 of the head 7a of the screw 7, the inside of the annular protrusion 3g can be covered with the head 7a of the screw 7. For this reason, it is possible to more reliably prevent the compressed tubular portion 6e from being exposed to the outside.
また、筒状部６ｅの肉厚ｔは、環状突出部３ｇの突出量Ｌ２より厚いので、ねじ７を締めたときにカバー部材３とねじ７の頭部７ａとの間に入り込んだ筒状部６ｅを確実に圧縮することが可能である。 Further, since the wall thickness t of the cylindrical portion 6e is thicker than the protruding amount L2 of the annular protruding portion 3g, the cylindrical portion that has entered between the cover member 3 and the head portion 7a of the screw 7 when the screw 7 is tightened. It is possible to reliably compress 6e.
また、挿通孔３ａと環状突出部３ｇとの直径方向における間隔Ｗは、筒状部６ｅの突出量Ｌ１より広いので、ねじ７を締めたときに筒状部６ｅが屈曲してカバー部材３とねじ７の頭部７ａとの間に入り込んだとしても、環状突出部３ｇの外には飛び出さない。このため、筒状部６ｅが外部に露出することをより確実に防止することが可能である。 Further, since the interval W in the diameter direction between the insertion hole 3a and the annular protrusion 3g is wider than the protrusion amount L1 of the cylindrical portion 6e, the cylindrical portion 6e bends when the screw 7 is tightened, and the cover member 3 Even if it enters between the head 7a of the screw 7, it does not jump out of the annular protrusion 3g. For this reason, it can prevent more reliably that the cylindrical part 6e is exposed outside.
また、ねじ７の頭部７ａが環状突出部３ｇに当接されて反対向面３ｆと頭部７ａとの間に形成される空間Ｓの容積は、筒状部６ｅの反対向面３ｆより突出している部位６ｆの体積よりも大きいので、ねじ７の頭部７ａが環状突出部３ｇに当接されたときに、カバー部材３とねじ７の頭部７ａとの間に入り込んだ筒状部６ｅは、カバー部材３と頭部７ａとの間の空間Ｓ内に収容される。このため、筒状部６ｅを外部に露出させることなく空間Ｓ内に収容することが可能である。 Further, the volume of the space S formed between the counter-opposing surface 3f and the head portion 7a when the head portion 7a of the screw 7 is brought into contact with the annular projecting portion 3g protrudes from the anti-opposing surface 3f of the cylindrical portion 6e. Since the volume of the portion 6f is larger, the cylindrical portion 6e that enters between the cover member 3 and the head portion 7a of the screw 7 when the head portion 7a of the screw 7 comes into contact with the annular projecting portion 3g. Is accommodated in the space S between the cover member 3 and the head 7a. For this reason, the cylindrical part 6e can be accommodated in the space S without being exposed to the outside.
上記実施形態においては、シール部材６がカバー部材３と一体成形されている例について説明したが、シール部材６とカバー部材３とは別部材であっても構わない。 In the above-described embodiment, the example in which the seal member 6 is integrally formed with the cover member 3 has been described, but the seal member 6 and the cover member 3 may be separate members.
上記実施形態においては、軒樋部材１に設けられている２つの排水孔１０ａの一方を塞ぐカバー部材３及びシール部材６の軒樋部材１への接合に本発明の接合構造を適用して例について説明したが、これに限るものではない。例えば、図２に示すような、軒樋部材１に設けられている排水孔１０ａと縦樋２とを連通させるための連結部材５の軒樋部材１への接合に適用しても構わない。この場合には、連結部材５を、上記カバー部材３の楕円止水部６ｂの内側に排水孔１０ａと連通する筒体部５ａを一体に備えている構成とすれば、接合構造は同一である。 In the above embodiment, an example in which the joint structure of the present invention is applied to the joint member 1 of the cover member 3 and the seal member 6 that block one of the two drain holes 10a provided in the joint member 1 is used. However, the present invention is not limited to this. For example, you may apply to the joining to the eaves member 1 of the connection member 5 for making the drain hole 10a provided in the eaves member 1 and the vertical rod 2 communicate, as shown in FIG. In this case, if the connecting member 5 is configured to integrally include the cylindrical body portion 5a communicating with the drain hole 10a inside the elliptical water blocking portion 6b of the cover member 3, the joining structure is the same. .
また、上記実施形態においては、軒樋部材１に対する接合構造を例に挙げて説明したが、これに限らず、止水性能を備えて２つの部材を接合する接合部であれば構わない。 Moreover, in the said embodiment, although demonstrated taking the example of the joining structure with respect to the eaves member 1, it is not restricted to this, What is necessary is just a junction part which joins two members with water stop performance.
また、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。 Moreover, the said embodiment is for making an understanding of this invention easy, and is not for limiting and interpreting this invention. The present invention can be changed and improved without departing from the gist thereof, and it is needless to say that the present invention includes equivalents thereof.
