Description
【０００１】[0001]
本考案は、例えば建築物外壁において、この外壁を構成している相隣接する外 壁材の間に生じる長尺細帯状の目地溝を閉塞するのに使用される目地材に関する ものである。 The present invention relates to a joint material used, for example, in an outer wall of a building to close a long narrow strip-shaped joint groove formed between adjacent outer wall materials forming the outer wall.
【０００２】[0002]
目地材には、種々の構造のものがあるが、その一つとして、上端部に嵌合凹部 が形成されていると共に、両側面にそれぞれシールリップが突設されて、目地溝 に嵌め込まれる目地本体と、該目地本体の嵌合凹部に嵌合される嵌合凸部が下面 に突設されて、目地溝の開口を塞ぐための目地カバーとから成るものがある。こ の目地材は、目地本体を目地溝に嵌め込むことにより、その両側面のシールリッ プを変形させて、目地溝の内壁面に弾接させ、その後に、目地カバーの嵌合凸部 を目地本体の嵌合凹部に押し込んで嵌合させ、この目地カバーにより目地溝の開 口を塞いでいる。シールリップを弾性変形させて、目地溝の内壁面に弾接させる ことより、目地溝をシールしている。 There are various types of joint materials, and one of them is a joint that has a fitting recess at the upper end and has sealing lips protruding on both sides to fit into the joint groove. In some cases, a main body and a joint cover, which is provided on a lower surface with a fitting convex portion to be fitted in a fitting concave portion of the joint main body, for covering the opening of the joint groove. With this joint material, by fitting the joint body into the joint groove, the seal lip on both sides of the joint body is deformed to make elastic contact with the inner wall surface of the joint groove, and then the fitting protrusion of the joint cover is jointed. It is pushed into the fitting recess of the main body to fit it, and the joint cover closes the opening of the joint groove. The seal groove is sealed by elastically deforming the seal lip and making elastic contact with the inner wall surface of the joint groove.
【０００３】 上記構造の目地材においては、そのシール性能は、目地溝の内壁面に対するシ ールリップの弾接力によって定まり、目地本体は殆ど変形しないので、このシー ル性能を高めるには、シールリップ単独の弾接力を高める他はなかった。また、 目地本体の嵌合凹部に目地カバーの嵌合凸部を嵌合させる場合においても、目地 本体の嵌合凹部が設けられている部分の変形範囲には、一定の限度があり、この ため嵌合凹部及び嵌合凸部の形状は、目地本体における嵌合凹部が設けられてい る部分の僅かの変形によって、両者が嵌合し合う形状に限定されて、両者の嵌合 による結合力は、それ程大きくできなかった。よって、施工中、或いは施工後に おいて、目地本体に対して目地カバーが外れ易いという問題もあった。In the joint material having the above structure, the sealing performance is determined by the elastic contact force of the seal lip with respect to the inner wall surface of the joint groove, and the joint main body is hardly deformed. There was no choice but to increase his elastic contact force. Even when the fitting protrusion of the joint cover is fitted into the fitting recess of the joint body, the deformation range of the portion of the joint body where the fitting recess is provided has a certain limit. The shape of the fitting recess and the fitting projection is limited to the shape in which the fitting recess is provided in the joint body due to slight deformation, and the coupling force due to the fitting , I couldn't make it that big. Therefore, there is a problem that the joint cover is easily detached from the joint body during or after the construction.

【考案が解決しようとする課題】 本考案は、目地本体と目地カバーとから成る目地材において、目地溝の内壁面 に対するシールリップの弾接力を大きくして、目地材の本来的機能であるシール 性を高め、併せて目地本体に対する目地カバーの結合力を大きくすることを課題 としてなされたものである。DISCLOSURE OF INVENTION Problem to be Solved by the Invention The present invention is directed to a joint material including a joint body and a joint cover, in which the elastic contact force of the seal lip with respect to the inner wall surface of the joint groove is increased so that the seal member has an original function of sealing. The purpose of this is to improve the adhesiveness and also to increase the joint strength of the joint cover to the joint body.

この課題を解決するために本考案の採用した手段は、上端部に嵌合凹部が形成 されていると共に、両側面にそれぞれシールリップが突設されて、目地溝に嵌め 込まれる目地本体と、該目地本体の嵌合凹部に嵌合される嵌合凸部が下面に突設 されて、目地溝の開口を塞ぐための目地カバーとから成る目地材において、前記 目地本体に、その嵌合凹部の底面に開口して該目地本体を変形し易くするための 縦溝を設けたことである。 In order to solve this problem, the means adopted by the present invention is a joint main body having a fitting recess formed at the upper end and protruding seal lips on both side surfaces to be fitted into a joint groove. A joint material having a joint cover, which is provided on a lower surface with a fitting convex portion that fits into the joint concave portion of the joint body, and a joint cover for closing the opening of the joint groove. A vertical groove is provided in the bottom surface of the joint to facilitate the deformation of the joint body.
【０００６】[0006]
目地本体に、その嵌合凹部の底面に開口した縦溝が設けられているので、この 目地本体を目地溝に挿入すると、シールリップが弾性変形して目地溝の内壁面に 弾接すると共に、目地本体における前記縦溝の部分を境にして、これよりも上方 の部分も弾性変形されて、その巾が狭くなる。よって、目地本体の嵌合凹部に目 地カバーの嵌合凸部を押し込んで嵌合させると、巾が狭くなっていた目地本体に おける縦溝よりも上方の部分は、原巾に拡開される。これにより、目地溝の内壁 面に対するシールリップの弾接力が増して、シール性が高まると同時に、シール リップの弾性復元力によって、目地カバーの嵌合凸部がその両側部から目地本体 によって挟まれるために、目地本体と目地カバーとの結合力も高まる。 Since the joint body is provided with a vertical groove that opens at the bottom of the fitting recess, when this joint body is inserted into the joint groove, the seal lip elastically deforms and makes elastic contact with the inner wall surface of the joint groove, and A part above the vertical groove in the main body is also elastically deformed, and its width is narrowed. Therefore, when the fitting convex part of the joint cover is pushed into the fitting concave part of the joint body to fit it, the part above the vertical groove in the joint body, which had been narrowed, is expanded to the original width. It This increases the elastic contact force of the seal lip against the inner wall surface of the joint groove to improve the sealing property, and at the same time, the elastic restoring force of the seal lip causes the fitting convex portion of the joint cover to be sandwiched by the joint body from both sides thereof. Therefore, the joint force between the joint body and the joint cover is also increased.

以下、実施例を挙げて本考案を更に詳細に説明する。図１は、本考案に係る目 地材Ａ1 を構成している目地本体１と目地カバー２とを分離した状態の斜視図で あり、図２は、目地本体１の断面図であり、図３は、目地溝Ｇに目地本体１を嵌 め込んだ状態の断面図であり、図４は、目地溝Ｇに嵌め込まれた目地本体１に目 地カバー２を嵌合させた状態の断面図である。なお、以下の説明において、「硬 質ゴム」、及び「軟質ゴム」の用語が使用されているが、この「硬質ゴム」とは 、ＪＩＳのＡ硬度で１００度程度のものをいい、「軟質ゴム」とは、同じく６０ 度程度のものをいう。図１及び図２において、目地本体１は、その全体が硬質ゴ ムで成形されて、本体部１ａの上端部には、円形断面の嵌合凹部３が上面に開口 して設けられ、本体部１ａの上面における嵌合凹部３に臨む部分は傾斜案内面４ となっており、その底面は平面状となっている。目地本体１の本体部１ａには、 これに設けられた嵌合凹部３の底面に開口する所定長さの縦溝５が設けられてい る。この縦溝５は、目地本体１の本体部１ａを変形し易くするためのものである 。また、目地本体１の本体部１ａの両側面には、それぞれ２対のシールリップ６ が突設されている。目地カバー２は、硬質ゴム、或いは硬質樹脂で成形され、そ の本体部２ａの下面に前記目地本体１の嵌合凹部３に嵌合される嵌合凸部７が突 設された構造である。Hereinafter, the present invention will be described in more detail with reference to examples. FIG. 1 is a perspective view showing a state in which a joint body 1 and a joint cover 2 constituting a joint material A 1 according to the present invention are separated, and FIG. 2 is a sectional view of the joint body 1. 3 is a sectional view of the joint main body 1 fitted in the joint groove G, and FIG. 4 is a sectional view of a joint cover 2 fitted in the joint main body 1 fitted in the joint groove G. Is. In the following description, the terms "hard rubber" and "soft rubber" are used. The "hard rubber" means a JIS A hardness of about 100 degrees, which means "soft rubber". Similarly, "rubber" means a rubber having a degree of about 60 degrees. 1 and 2, the joint main body 1 is entirely formed of a hard rubber, and a fitting recess 3 having a circular cross section is provided at the upper end of the main body 1a with an opening on the upper surface. A portion of the upper surface of 1a facing the fitting recess 3 is an inclined guide surface 4, and its bottom surface is flat. The joint body 1a of the joint body 1 is provided with a vertical groove 5 of a predetermined length that opens to the bottom surface of the fitting recess 3 provided therein. The vertical groove 5 is for facilitating the deformation of the main body portion 1a of the joint main body 1. Further, two pairs of seal lips 6 are provided on both side surfaces of the main body 1a of the joint main body 1, respectively. The joint cover 2 is made of hard rubber or hard resin, and has a structure in which a fitting convex portion 7 to be fitted in the fitting concave portion 3 of the joint main body 1 is provided on the lower surface of the main body portion 2a. .
【０００８】 そして、この目地材Ａ1 を使用して目地溝Ｇを閉塞するには、以下のようにし て行う。建築物の外壁を構成している相隣接する外壁材８の各端面と、バックア ップ材９とによって長尺細帯状の目地溝Ｇが形成されており、図３に示されるよ うに、この目地溝Ｇに目地本体１を嵌め込んで、その平面状の底面をバックアッ プ材９に当接させると、通常の目地材と同様にして、シールリップ６が弾性変形 して目地溝Ｇの内壁面Ｇａに弾接すると共に、目地材１の本体部１ａには、これ に設けた嵌合凹部３の底面に開口する縦溝５が設けられているために、このシー ルリップ６の弾性復元力によって、目地本体１の本体部１ａのほぼ全体が、その 巾が狭くなるように弾性変形される。従って、この状態における目地本体１の嵌 合凹部３の大きさは、非変形時に比較して小さくなっている。次に、目地溝Ｇに 嵌め込まれた目地本体１の嵌合凹部３に目地カバー２の嵌合凸部７を押し込むと 、目地本体１の本体部１ａは、シールリップ６の弾性復元力に抗して、両側に押 し拡げられてその巾が原巾に復元して、目地本体１の嵌合凹部３に目地カバー２ の嵌合凸部７が嵌合されて、目地溝Ｇの開口が目地カバー２により塞がれる。Then, the joint groove A is closed using the joint material A 1 in the following manner. As shown in FIG. 3, a long narrow strip-shaped joint groove G is formed by the back-up member 9 and the end faces of the adjacent outer-wall members 8 constituting the outer wall of the building. When the joint main body 1 is fitted into the joint groove G and the planar bottom surface of the joint main body 1 is brought into contact with the back-up member 9, the seal lip 6 is elastically deformed in the same manner as a normal joint member so that the inside of the joint groove G is Since the main body portion 1a of the joint material 1 is provided with the vertical groove 5 opening to the bottom surface of the fitting concave portion 3 provided therein, the elastic restoring force of the seal lip 6 causes Almost the entire main body portion 1a of the joint main body 1 is elastically deformed so that its width becomes narrow. Therefore, the size of the fitting concave portion 3 of the joint body 1 in this state is smaller than that in the non-deformed state. Next, when the fitting projection 7 of the joint cover 2 is pushed into the fitting recess 3 of the joint body 1 fitted in the joint groove G, the body portion 1a of the joint body 1 resists the elastic restoring force of the seal lip 6. Then, the width is restored to the original width by pushing and expanding to both sides, and the fitting convex portion 7 of the joint cover 2 is fitted into the fitting concave portion 3 of the joint body 1 to open the joint groove G. It is closed by the joint cover 2.
【０００９】 上記したようにして、狭巾にさせられていた目地本体１の本体部１ａが原巾に 復元することにより、目地溝Ｇの内壁面Ｇａに弾接している各シールリップ６の 変形量が大きくなって、内壁面Ｇａに対するシールリップ６の弾接力が増し、こ の結果、目地材の本来的機能であるシール性が高められる。一方、目地溝Ｇの内 壁面Ｇａに弾接している各シールリップ６の弾性復元力は、目地本体１の本体部 １ａに対しては、この本体部１ａの巾を狭くするように作用する。このため、目 地本体１の嵌合凹部３に嵌合している目地カバー２の嵌合凸部７は、各シールリ ップ６の弾性復元力により、その両側から目地本体１の本体部１ａによって強く 挟み込まれる。よって、目地本体１の嵌合凹部３に目地カバー２の嵌合凸部７が 嵌合した後における目地本体１と目地カバー２との結合力が高まって、目地本体 １に対して目地カバー２が外れにくくなる。なお、目地本体１におけるシールリ ップ６の部分は、軟質ゴムで成形することもできる。As described above, the main body portion 1a of the joint body 1 which has been made narrower is restored to the original width, whereby the deformation of each seal lip 6 elastically contacting the inner wall surface Ga of the joint groove G is restored. As the amount increases, the elastic contact force of the seal lip 6 against the inner wall surface Ga increases, and as a result, the sealability, which is an essential function of the joint material, is improved. On the other hand, the elastic restoring force of each seal lip 6 elastically contacting the inner wall surface Ga of the joint groove G acts on the body portion 1a of the joint body 1 so as to narrow the width of the body portion 1a. Therefore, the fitting protrusions 7 of the joint cover 2 fitted in the fitting recesses 3 of the joint body 1 are elastically restored by the respective seal lips 6 from both sides thereof to the body portion 1a of the joint body 1. It is strongly sandwiched by. Therefore, the joint force between the joint main body 1 and the joint cover 2 after the fitting convex portion 7 of the joint cover 2 is fitted into the fitting concave portion 3 of the joint main body 1, and the joint cover 2 with respect to the joint main body 1 is increased. Will not come off easily. The seal lip 6 portion of the joint body 1 may be made of soft rubber.
【００１０】 次に、図５ないし図８を参照にして、本考案の他の実施例の目地材Ａ2 につい て説明する。図５は、本考案に係る目地材Ａ2 を構成している目地本体１１と目 地カバー１２とを分離した状態の斜視図であり、図６は、目地本体１１の断面図 であり、図７は、目地溝Ｇ’に目地本体１１を嵌め込んだ状態の断面図であり、 図８は、目地溝Ｇ’に嵌め込まれた目地本体１１に目地カバー１２を嵌合させた 状態の断面図である。図５及び図６に示されるように、この目地材Ａ2 は、上記 目地溝Ｇよりも深い目地溝Ｇ’に対応させたものであって、その目地本体１１は 、目地溝Ｇ’の深さに対応した高さを有している。この目地本体１１の本体部１ １ａは、硬質ゴムで成形されて、高さ方向に沿ったほぼ中央部にくびれ部１１ｂ が設けられて、このくびれ部１１ｂの上方と下方の部分に、それぞれ中空部１１ ｃ，１１ｄが形成されている。目地本体１１の本体部１１ａの上端部には、断面 がほぼ半円形の嵌合凹部１３が上面に開口して設けられ、本体部１１ａの上面に おける嵌合凹部１３に臨む部分は傾斜案内面１４となっている。この一対の傾斜 案内面１４の下端の部分には、一対の補助嵌合凸部１８が相対向して設けられて いる。目地本体１１の本体部１１ａにおける中空部１１ｃの上方の部分には、こ れに設けられた前記嵌合凹部１３の底面に開口する縦溝１５が設けられている。 また、目地本体１１の本体部１１ａにおける前記くびれ部１１ｂよりも上方の部 分の両側面には、それぞれ３対のシールリップ１６が突設されている。このシー ルリップ１６は、軟質ゴムで成形されている。一方、目地カバー１２は、硬質ゴ ム、或いは硬質樹脂で成形されていて、その本体部１２ａの下面に嵌合凸部１７ が突設され、この嵌合凸部１７の基端部の両側面に、前記補助嵌合凸部１８に対 応する補助嵌合凹部１９が設けられている。Next, a joint material A 2 according to another embodiment of the present invention will be described with reference to FIGS. 5 to 8. FIG. 5 is a perspective view showing a state in which the joint body 11 and the joint cover 12 which constitute the joint material A 2 according to the present invention are separated, and FIG. 6 is a sectional view of the joint body 11. 7 is a sectional view of the joint main body 11 fitted in the joint groove G ′, and FIG. 8 is a sectional view of a joint cover 12 fitted in the joint main body 11 fitted in the joint groove G ′. Is. As shown in FIGS. 5 and 6, the joint material A 2 corresponds to a joint groove G ′ deeper than the joint groove G, and the joint main body 11 has a depth of the joint groove G ′. It has a height corresponding to the height. The main body portion 11a of the joint main body 11 is made of hard rubber, and a constricted portion 11b is provided at a substantially central portion along the height direction, and hollow portions are provided above and below the constricted portion 11b. Portions 11c and 11d are formed. A fitting recess 13 having a substantially semicircular cross section is provided at the upper end of the main body 11a of the joint main body 11 with an opening on the upper surface, and a portion of the upper surface of the main body 11a facing the fitting recess 13 is an inclined guide surface. It is 14. A pair of auxiliary fitting convex portions 18 are provided at the lower ends of the pair of inclined guide surfaces 14 so as to face each other. A vertical groove 15 that opens to the bottom surface of the fitting recess 13 provided in the main body portion 11a of the joint main body 11 above the hollow portion 11c is provided.

Further, an auxiliary fitting concave portion 19 corresponding to the auxiliary fitting convex portion 18 is provided.
【００１１】 そして、図７に示されるように、目地溝Ｇ’に目地本体１１を嵌め込んで、そ の底部をバックアップ材９に当接させると、各シールリップ１６は弾性変形して 内壁面Ｇ'aに弾接する。目地本体１１の本体部１１ａには上記した縦溝１５が設 けられていて、この本体部１１ａにおける縦溝１５を境にしてこれよりも上方の 部分は、変形し易くなっているので、上方から起算して２対の各シールリップ１ ６の弾性復元力によって、目地本体１１の本体部１１ａの上記部分は、その巾が 狭くなるように弾性変形される。これにより、目地本体１１の嵌合凹部１３は、 非変形時よりも小さくなっており、この状態で、目地本体１１の嵌合凹部１３に 目地カバー１２の嵌合凸部１７を押し込んで嵌合させると、図８に示されるよう に、目地本体１１の本体部１１ａの上端部は、各シールリップ１６の弾性復元力 に抗して、両側に押し拡げられてその巾が原巾に復元して、目地溝Ｇ’の開口が 目地カバー１２により塞がれる。この目地材Ａ2 においても、上記目地材Ａ1 に ついて説明したのとほぼ同様の理由によって、シール性が高まると共に、目地本 体１１に対して目地カバー１２が外れにくくなる。Then, as shown in FIG. 7, when the joint main body 11 is fitted into the joint groove G ′ and the bottom portion thereof is brought into contact with the backup material 9, each seal lip 16 is elastically deformed and the inner wall surface. Elastically contact G'a. The above-described vertical groove 15 is provided in the main body portion 11a of the joint main body 11, and the portion above the vertical groove 15 in the main body portion 11a is easily deformed. By the elastic restoring force of the two pairs of seal lips 16 calculated from the above, the above-mentioned portion of the main body portion 11a of the joint main body 11 is elastically deformed so that the width thereof becomes narrow. As a result, the fitting concave portion 13 of the joint main body 11 is smaller than that when it is not deformed, and in this state, the fitting convex portion 17 of the joint cover 12 is pushed into the fitting concave portion 13 of the joint main body 11 for fitting. Then, as shown in FIG. 8, the upper end portion of the main body portion 11a of the joint main body 11 is expanded to both sides against the elastic restoring force of each seal lip 16 and its width is restored to the original width. Then, the opening of the joint groove G ′ is closed by the joint cover 12. In this joint material A 2 as well, the sealability is improved and the joint cover 12 is less likely to come off from the joint body 11 for almost the same reason as described for the joint material A 1 .
【００１２】 また、図９及び図１０に、本考案に係る更に別の目地材Ａ3 が示されているが 、この目地材Ａ3 の全体形状は前記目地材Ａ2 とほぼ同じであるので、目地材Ａ 2 と同一部分には同一符号を使用して、異なる部分についてのみ説明する。この 目地材Ａ3 の目地本体１１は、その上端部、及び芯部が硬質ゴムで成形されて、 その他の部分は、全て軟質ゴムで成形されている。目地本体１１の硬質ゴムで成 形されている部分には、嵌合凹部１３と縦溝１５とが設けられている。この実施 例の目地材Ａ3 は、上記した各目地材Ａ1,Ａ2 と同様に、シール性が高まると共 に、目地本体１１に対して目地カバー１２が外れにくくなる効果に加えて、目地 本体１１の芯部を除く部分が全て軟質ゴムで成形されているために、目地溝Ｇ’ に対する目地本体１１の挿入性が高まる利点がある。9 and 10 show another joint material A according to the present invention.3Is shown, but this joint material A3The overall shape of the joint material A2Since it is almost the same as, 2 The same reference numerals are used for the same portions as, and only different portions will be described. This joint material A3The joint body 11 has an upper end portion and a core portion made of hard rubber, and the other portions are all made of soft rubber. A fitting recess 13 and a vertical groove 15 are provided in a portion of the joint body 11 which is formed of hard rubber. Joint material A of this example3Is each joint material A described above1,A2Similarly, in addition to the improved sealability, in addition to the effect that the joint cover 12 does not come off easily from the joint main body 11, the part of the joint main body 11 excluding the core is molded of soft rubber. , There is an advantage that the insertability of the joint main body 11 into the joint groove G ′ is enhanced.
【００１３】[0013]
本考案は、上端部に嵌合凹部が形成されていると共に、両側面にそれぞれシー ルリップが突設されて、目地溝に嵌め込まれる目地本体と、該目地本体の嵌合凹 部に嵌合される嵌合凸部が下面に突設されて、目地溝の開口を塞ぐための目地カ バーとから成る目地材において、前記目地本体に、その嵌合凹部の底面に開口し て該目地本体を変形し易くするための縦溝を設けたので、この目地本体を目地溝 に挿入すると、シールリップが弾性変形して目地溝の内壁面に弾接すると共に、 目地本体における前記縦溝の部分を境にして、これよりも上方の部分も弾性変形 されて、狭巾となる。よって、目地本体の嵌合凹部に目地カバーの嵌合凸部を押 し込んで嵌合させると、狭巾となっていた目地本体における縦溝よりも上方の部 分は、原巾に拡開される。これにより、目地溝の内壁面に対するシールリップの 弾接力が増して、シール性が高まると同時に、シールリップの弾性復元力によっ て、目地カバーの嵌合凸部の両側が目地本体の嵌合凹部の周辺の部分によって挟 まれるために、目地本体と目地カバーとの結合力も高まって、施工後において目 地本体に対して目地カバーが外れにくくなる。 According to the present invention, the fitting recess is formed at the upper end, and the seal lips are respectively provided on both side surfaces so as to project into the joint groove, and the joint body is fitted into the fitting recess of the joint body. In a joint material that is formed by a fitting convex portion protruding from the bottom surface and a joint cover for closing the opening of the joint groove, the joint main body is opened at the bottom of the fitting concave portion, and the joint main body is opened. Since a vertical groove is provided to make it easier to deform, when this joint body is inserted into the joint groove, the seal lip elastically deforms and makes elastic contact with the inner wall surface of the joint groove, and the part of the vertical groove in the joint body is the boundary. Then, the portion above this is also elastically deformed and becomes narrow. Therefore, when the fitting convex part of the joint cover is pushed into the fitting concave part of the joint body to fit it, the part above the vertical groove in the joint body, which was narrow, expands to the original width. To be done. As a result, the elastic contact force of the seal lip against the inner wall surface of the joint groove is increased to improve the sealing property, and at the same time, the elastic restoring force of the seal lip causes both sides of the fitting convex portion of the joint cover to fit the joint body. Since it is sandwiched by the peripheral portion of the recess, the joint force between the joint body and the joint cover also increases, and the joint cover does not easily come off from the joint body after construction.
