【０００１】
【発明の属する技術分野】
本発明は、パネルやタイル等の建築資材を張ったときに生じる継ぎ目（目地）に嵌め込んで止水性や意匠性を確保する目地材に関するものである。
【０００２】
【従来の技術】
従来、この種の目地材が特許文献１等に開示されている。即ち、図１８（ａ）に示すように、目地材５１は同図の左右方向に突出する弾性変形可能な複数のヒレ部５２を有し、目地材５１がパネル５３間に生じた目地溝５４に嵌入されたときにはヒレ部５２が変形した状態で目地溝５４の内側壁５４ａに弾性接触する。

【０００４】
【発明が解決しようとする課題】
しかしながら、図１８（ａ）に示す狭い目地幅Ｗ１では、目地材５１がちょうどよい状態で取り付けられるものの、同じ目地材５１を図１８（ｂ）に示す広い目地幅Ｗ２（＞Ｗ１）の目地溝５４に取り付けると、最外側に位置するヒレ部５２の先端が低い位置で内側壁５４ａと接触することになる。このため、目地溝５４の内側壁５４ａの一部が外部に露出し、戸口が見える状態になって外観が低下するとともに、目地材５１による止水性に悪影響が生じるという問題が生じていた。
【０００５】
本発明は前記の問題点に鑑みてなされたものであって、その目的は、異なる幅の溝部に同じ部品を用いても、良好な外観を得ることができるとともに、充分な止水性を確保できる目地材を提供することにある。
【０００６】
【課題を解決するための手段】
上記問題点を解決するために、請求項１に記載の発明では、芯材と弾性変形可能なヒレ部とを有し、溝部に嵌め込まれる目地材において、目地材本体の底面には該目地材本体と切り離し可能な台座が形成されるとともに、前記台座と前記目地材本体とは、連結部を介して一体に連結されており、前記台座は、その幅方向の中心部に位置する柱部と、該柱部の上部に位置するとともに前記目地材本体を支持する第１支持部と、前記柱部の下部に位置するとともに目地材全体を支持する第２支持部とを有する断面エ字形状をなし、前記連結部は、前記柱部より幅狭に複数形成され、前記目地材本体の長手方向に延びており、前記台座を、前記第１支持部及び第２支持部が前記柱部を支点として一方が他方に対して傾くように構成するとともに、前記第２支持部の幅を前記芯材の幅よりも大きくしたことを要旨とする。この発明によれば、溝幅が大きい場合には台座を付けたままで目地材を使用し、溝幅が小さい場合には台座を切り離して目地材を使用することにより、異なる幅の溝部に同じ目地材を使用しても、溝部の壁面が露出しない状態で目地材が取り付けられる。従って、異なる幅の溝部に同じ部品を用いても、外観の低下を招くことがないとともに、充分な止水性を確保可能となる。
【０００７】
また、第２支持部の幅を芯材の幅よりも大きくしたので、目地材を溝部に嵌め込むときに第２支持部が溝部の内面に接触し易くなり、接触した際に第２支持部は溝部の内面から離間する方向に押し戻される。従って、目地材は傾いた取付状態となり難く、ほぼ立った状態で取り付けられることになり、ヒレ部によるシール力にバラツキが生じ難くなり、高い止水性が確保可能となる。
【０００８】
また、前記台座と前記目地材本体とは、幅狭の連結部を介して一体に連結されているため、台座を目地材本体から簡単に切り離せる。
【０００９】
さらに、前記連結部は複数形成され、前記目地材本体の長手方向に延びているため、目地材を押出し成形により簡単に製造することが可能となり、目地材を低コストで製造可能となる。
【００１０】
また、目地材本体が柱部を支点として台座に対し傾くことが可能となり、例えば溝部の底面が傾斜していてもその傾き作用により目地材の取付姿勢が好適な状態を保つこととなる。
【００１１】
請求項２に記載の発明では、請求項１に記載の発明において、前記台座は、前記柱部の少なくとも一部が薄肉に形成されていることを要旨とする。この発明によれば、請求項１に記載の発明の作用に加え、この薄肉部分で台座を切断することにより目地材の高さが変えられるので、溝幅の広狭に対して柔軟に対応可能となる。
【００１２】
請求項３に記載の発明では、請求項１又は２に記載の発明において、前記台座には、弾性変形して前記溝部の内面に接触可能なヒレ部が形成されていることを要旨とする。この発明によれば、請求項１又は２の発明の作用に加え、台座にもヒレ部が形成されているので、シールする部分が増えることになり、止水性が向上する。
【００１３】
請求項４に記載の発明では、請求項１〜３のうちいずれか一項に記載の発明において、前記台座は、中空状に形成されていることを要旨とする。この発明によれば、請求項１〜３のうちいずれか一項に記載の発明の作用に加え、台座自体が上下方向等に大きく変形することが可能となるので、台座を付けている状態でも目地材の位置や姿勢を柔軟に調整することが可能となる。
請求項５に記載の発明では、請求項１〜４のうちいずれか一項に記載の発明において、前記第２支持部は、その最下面が平らに形成されていることを要旨とする。
【００１４】
【発明の実施の形態】
以下、本発明を住宅用の外壁パネル間の継ぎ目（目地）に嵌入される目地材に具体化した一実施形態を図１〜図９に従って説明する。
【００１５】
図１〜図５に示すように、台付き目地材（以下、単に目地材と記す）１は例えばＥＰＤＭゴム等のエラストマーを材質としており、長手方向に連続する長尺状をなすとともに、断面が左右対称形状となっている。この目地材１は適当な長さに切断されて施工に用いられる。なお、本例の左右方向は図１における上下、左右をいうものとする。目地材１は目地材本体２と、目地材本体２の底面に位置する台座３とが一体形成されている。
【００１６】
目地材本体２は中心部に位置し所定の肉厚に形成された芯材４と、その芯材４から左右方向に突出するとともに上下方向に３つ並んだヒレ部５〜７を備えている。上側のヒレ部５と中間のヒレ部６との間には、芯材４を挟んで両側に断面く字形状の屈曲部８が形成されている。また、上側のヒレ部５の上面には２色同時成形による意匠層９が形成され、本例ではその意匠層９とその他の部位とが異なる色となっている。
【００１７】
台座３は断面略エ字形状に形成され、その中心部には上下方向に延びる柱部１０を備えている。柱部１０の上部には目地材本体２を支持する第１支持部１１が形成され、柱部１０の下部には目地材１全体を支える第２支持部１２が形成されている。第２支持部１２の幅Ｌ１は芯材４の幅Ｌ２よりも大きく設定されている。
【００１８】
目地材本体２と台座３との間には、これらを一体に連結するために台座３の上面から部分的に突出した連結部１３が複数（本例は３つ）形成されている。各連結部１３は芯材４や柱部１０よりも幅が小さく設定され、目地材１の長手方向全域に沿って延びている。また、目地材本体２と台座３は連結部１３の部分において比較的小さな力で分離可能となっている。
【００１９】
図６〜図９に示すように、目地材１は住宅用の外壁パネル（建築用ボード）１４，１４の間に生じる目地溝（溝部）１５に嵌入して使用し、この目地部分の止水性を確保するとともに、目地溝１５の開口部位の意匠性を維持する。台座３が目地溝１５の底面１６に接触した取付状態では、ヒレ部５〜７が湾曲して目地溝１５の内側壁（内面）１７に弾性接触した状態となり、止水性が確保された状態となる。
【００２０】
さて、図６に示すように幅が比較的広い目地幅Ｗ２の目地溝１５ａに目地材１を嵌入する場合、台座３を付けたままにしておく。このとき、ヒレ部５〜７が湾曲しその湾曲状態で内側壁１７に弾性接触するが、この取付状態では上側のヒレ部５の先端が外壁パネル１４の外面とほぼ面一の状態となり、目地溝１５の内側壁１７がほとんど露出しないので、止水性が高く外観もよい取付状態となる。
【００２１】
また、取付時において図７に示すように目地材１が目地溝１５に対して傾いた状態（同図の実線で示す状態）で挿入されることがあるが、第２支持部１２の幅Ｌ１は芯材の幅Ｌ２よりも大きく設定されているので、第２支持部１２は一方（同図では左側）の先端が内側壁１７に接触して湾曲した状態となる。このとき、第２支持部１２の先端には真っ直ぐになろうとする力が働き、目地材１が同図の矢印方向に動いて目地溝１５に対して傾きが抑制された状態（同図の二点鎖線で示す状態）となる。従って、傾いたままで目地材１が目地溝１５に取り付けられずに済み、ヒレ部５〜７によるシール部分に偏りが生じ難くなり、高い止水性が確保される。
【００２２】
一方、図８に示すように幅が比較的狭い目地幅Ｗ１の目地溝１５ｂに目地材１を嵌入する場合、台座３を連結部１３の部位で目地材本体２から分離する。そして、目地溝１５ｂに対する目地材１の嵌入状態では、ヒレ部５〜７が大きく湾曲するため、目地材本体２の高さ寸法が大きくなる。このため、上側のヒレ部５の先端が外壁パネル１４の外面とほぼ面一の状態となり、狭い目地幅Ｗ１においても止水性及び外観が確保される。
【００２３】
従って、この実施形態では以下のような効果を得ることができる。
（１）目地材１に台座３を設け、目地幅が広いときには台座３を付けた状態で目地溝１５に嵌入し、目地幅が狭いときには台座３を目地材本体２から切り離して使用する構成とした。従って、同じ目地材１を目地幅の異なる目地溝１５ａ、１５ｂに共通使用しても、その取付状態では目地溝１５ａ，１５ｂともにその内側壁１７がほとんど露出せずに済み、水が目地溝１５ａ，１５ｂに侵入し難くなって止水性を確保できる。また、この取付状態では上側のヒレ部５の先端と外壁パネル１４の上面がほぼ面一となるので、外観もよい。
【００２４】
（２）第２支持部１２の幅Ｌ１は芯材の幅Ｌ２よりも大きく設定されているので、目地材１が傾いた状態で目地溝１５に挿入されても、湾曲して目地溝１５の内側壁１７に接触した第２支持部１２が元の真っ直ぐの状態に戻ろうとする変形作用により、目地材１は目地溝１５内部で、ほぼ立った状態となる。従って、傾いたままで目地材１が目地溝１５に取り付けられずに済み、ヒレ部５〜７によるシール部分に偏りが生じ難くなり、高い止水性を確保することができる。
【００２５】
（３）目地材本体２と台座３との連結部位である連結部１３は、切り離し易くなるように他の部位に比べて幅狭に形成されているので、台座３を簡単に切り離すことができる。
【００２６】
（４）連結部１３は目地材１の長手方向全域に沿って延びる構成であるので、押出し成形により簡単に製造することができ、製造コストを低くすることができる。
【００２７】
（５）台座３は断面略エ字形状に形成されているので、各支持部１１，１２は柱部１０を支点として一方が他方に対して傾くことが可能である。従って、図９に示すように目地溝１５の底面１６が傾斜していても、その傾斜に合わせて下側の第２支持部１２が傾斜することになり、目地材本体２は目地溝１５の内側壁１７に対して好適な姿勢を保った状態となる。このため、ヒレ部５〜７によるシール力にバラツキが生じ難くなり、高い止水性を確保できる。また、底面１６が傾いていても、ヒレ部５の先端を外壁パネル１４の外面とほぼ同一に位置させることができるので、良好な外観を保つこともできる。
【００２８】
なお、実施形態は前記に限定されず、例えば図１０〜図１７に示す次の態様に変更してもよい。ここで、以下に示す態様は上記実施形態と基本的な構造は同じであるので、異なる部分についてのみ説明する。また、図１０〜図１６の各例は側面図のみを示したが、他の面も前記実施形態と同様な形態で表れるものとする。
【００２９】
・ 図１０に示すように、台座３の柱部１０の肉厚を前記実施形態よりも薄くしてもよい。この場合、柱部１０で台座３を容易に切断でき、これにより台座３を２分割することができる。従って、目地材１の全体高さをより柔軟に調節でき、多くの目地幅の目地溝に対応できる。
【００３０】
・ 図１１に示すように、台座３を充実の断面台形状としてもよい。この場合、目地材１は左右方向に傾き難くなるので、例えば目地溝１５の底面１６が水平で、それに沿って目地材１を真っ直ぐ立たせたい場合には、同図に示す目地材１を用いればよい。
【００３１】
・ 図１２に示すように、台座３の下側の支持部１２の先端を、さらに突出させてヒレ部２１を形成してもよい。この場合、目地材１全体としてヒレ部の個数が増えることにより、シールする部分が増えて止水性が一層向上する。
【００３２】
・ 図１３に示すように、台座３の柱部１０の両側部に切欠部２２を形成して柱部１０の一部を薄肉としてもよい。この場合、切欠部２２で台座３を容易に切断でき、１つの部品で多くの目地幅に対応できる。また、連結部１３の個数は３つに限らず、同図に示すように２つとしてもよいし、或いは１つや４つ以上を採用してもよい。
【００３３】
・ 図１４に示すように、目地材本体２の上側のヒレ部５を略平板状としてもよい。また、上側のヒレ部５と中間のヒレ部６とを繋ぐ屈曲部８を省略してもよい。
【００３４】
・ 図１５に示すように、台座３を中空状にして内部に空間部２３を形成してもよい。この場合、台座３が上下、左右方向に容易に変形可能となるので、目地材１は台座３を付けたままであっても、台座３の変形作用により上下方向の高さや傾斜角度が容易に変化する。従って、この変化分だけ目地幅変化や目地溝１５の傾斜に対してに対応可能となり、汎用性が増す。
【００３５】
・ 図１６に示すように、第１支持部１１の左右両側にヒレ部２４を設けてもよい。また、第１支持部１１とともに第２支持部１２にもヒレ部２５を設けて、第１支持部１１及び第２支持部１２の両方がヒレ部を有する構成としてもよい。
【００３６】
・ 実施形態及び図１０〜１６に記載の目地材１の特徴的構成を組み合わせてもよい。例えば、柱部１０を薄肉とした構成（図１０参照）と、台座３にヒレ部２１を設ける構成（図１２参照）とを組み合わせてもよい。また、同様に図１２に示す構成と、台座３に空間部２３を設ける構成（図１５参照）とを組み合わせてもよい。
【００３７】
・ 目地材１の意匠層９は、例えば図１７に示すように表面９ａにシボ面を有する形状としてもよい。
・ 目地材の素材はゴムに限らず、合成樹脂や金属を用いてもよい。
【００３８】
【発明の効果】
以上詳述したように本発明によれば、取付先の溝部の溝幅に応じて台座を切り離して使用することで、異なる幅の溝部に対して良好な意匠性を維持するとともに、充分な止水性を確保できる。

[0003]
[Patent Document 1]
Japanese Utility Model Publication No. 5-16913 (2nd page, Fig. 1)
[0004]
[Problems to be solved by the invention]
However, in the narrow joint width W1 shown in FIG. 18 (a), the joint material 51 is attached in a just right state, but the same joint material 51 is connected to the joint groove having the wide joint width W2 (> W1) shown in FIG. 18 (b). When attached to 54, the tip of the fin portion 52 located on the outermost side comes into contact with the inner wall 54a at a low position. For this reason, a part of the inner side wall 54a of the joint groove 54 is exposed to the outside, the door is visible, the appearance is deteriorated, and the water stoppage due to the joint material 51 is adversely affected.
[0005]
The present invention has been made in view of the above-mentioned problems, and the object thereof is to obtain a good appearance even when the same parts are used for grooves having different widths and to ensure sufficient water-stopping. It is to provide joint materials.
[0006]
[Means for Solving the Problems]
In order to solve the above problems, in the invention according to claim 1, in the joint material having a core member and an elastically deformable fin portion, and being fitted in the groove portion, the joint material is provided on the bottom surface of the joint material body. Rutotomoni is formed body and detachable seat, and the seat and the joint member main body is integrally connected via the connecting portion, the pedestal, and the bar portion in the center in the width direction And a first support part located above the pillar part and supporting the joint material body, and a second support part located below the pillar part and supporting the whole joint material. None, the plurality of connecting portions are formed to be narrower than the column portion, and extend in the longitudinal direction of the joint material main body, and the pedestal, the first support portion and the second support portion support the column portion. As one side is inclined with respect to the other and the front The width of the second support section and summarized in that is larger than the width of the core material. According to this invention, when the groove width is large, the joint material is used with the pedestal attached, and when the groove width is small, the joint material is used by separating the pedestal, so that the same joint is formed in the groove portions having different widths. Even if the material is used, the joint material is attached in a state where the wall surface of the groove portion is not exposed. Therefore, even if the same parts are used for the groove portions having different widths, the appearance is not deteriorated and sufficient water stoppage can be ensured.
[0007]
Further, since the width of the second support portion is made larger than the width of the core material, the second support portion can easily come into contact with the inner surface of the groove portion when the joint material is fitted into the groove portion, and the second support portion can be brought into contact with the second support portion. Is pushed back in a direction away from the inner surface of the groove. Therefore, the joint material is hardly attached in an inclined state, and is attached in an almost standing state, so that the sealing force due to the fin portion is less likely to vary, and high water stoppage can be secured.
[0008]
Moreover, since the said base and the said joint material main body are integrally connected via the narrow connection part , a base can be easily separated from a joint material main body.
[0009]
Further , since the plurality of connecting portions are formed and extend in the longitudinal direction of the joint material body , the joint material can be easily manufactured by extrusion molding, and the joint material can be manufactured at low cost.
[0010]
Further, the joint material main body can be tilted with respect to the pedestal using the column portion as a fulcrum. For example, even if the bottom surface of the groove portion is tilted, the mounting posture of the joint material is maintained in a suitable state by the tilting action.
[0011]
The invention according to claim 2 is summarized in that, in the invention according to claim 1 , at least a part of the column part is formed thin. According to this invention, in addition to the action of the invention according to claim 1 , since the height of the joint material can be changed by cutting the pedestal at this thin portion, it is possible to flexibly cope with the width of the groove. Become.
[0012]
The gist of the invention described in claim 3 is that, in the invention described in claim 1 or 2 , the pedestal is formed with a fin portion that can be elastically deformed and contact the inner surface of the groove portion. According to this invention, in addition to the effect of the invention of claim 1 or 2 , since the fin portion is also formed on the pedestal, the portion to be sealed is increased, and the water stoppage is improved.
[0013]
The invention according to claim 4 is the gist of the invention according to any one of claims 1 to 3 , wherein the pedestal is formed in a hollow shape. According to this invention, in addition to the action of the invention according to any one of claims 1 to 3 , the pedestal itself can be greatly deformed in the vertical direction or the like. It is possible to flexibly adjust the position and posture of the joint material.
The invention according to claim 5 is the gist of the invention according to any one of claims 1 to 4, wherein the second support portion has a flat bottom surface.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment in which the present invention is embodied in a joint material inserted into a joint (joint) between outer wall panels for a house will be described with reference to FIGS.
[0015]
As shown in FIGS. 1 to 5, a jointed joint material (hereinafter simply referred to as joint material) 1 is made of an elastomer such as EPDM rubber, and has a continuous shape in the longitudinal direction and a cross section. It has a symmetrical shape. This joint material 1 is cut into an appropriate length and used for construction. In addition, the left-right direction of this example shall mean the up-down and left-right in FIG. In the joint material 1, a joint material main body 2 and a pedestal 3 positioned on the bottom surface of the joint material main body 2 are integrally formed.
[0016]
The joint material main body 2 includes a core member 4 that is positioned at the center and formed to have a predetermined thickness, and fins 5 to 7 that protrude from the core member 4 in the left-right direction and are lined up in the vertical direction. . Between the upper fin portion 5 and the intermediate fin portion 6, bent portions 8 having a square cross section are formed on both sides of the core material 4. In addition, a design layer 9 is formed on the upper surface of the upper fin portion 5 by two-color simultaneous molding. In this example, the design layer 9 and other portions have different colors.
[0017]
The pedestal 3 is formed in a substantially E-shaped cross section, and has a column portion 10 extending in the vertical direction at the center thereof. A first support portion 11 that supports the joint material body 2 is formed at the upper portion of the column portion 10, and a second support portion 12 that supports the entire joint material 1 is formed at the lower portion of the column portion 10. The width L1 of the second support portion 12 is set to be larger than the width L2 of the core material 4.
[0018]
Between the joint material main body 2 and the pedestal 3, a plurality (three in this example) of connecting portions 13 that partially protrude from the upper surface of the pedestal 3 are formed in order to connect them together. Each connecting portion 13 is set to have a width smaller than that of the core material 4 and the column portion 10, and extends along the entire longitudinal direction of the joint material 1. Further, the joint material main body 2 and the pedestal 3 can be separated by a relatively small force at the connecting portion 13.
[0019]
As shown in FIGS. 6 to 9, the joint material 1 is used by being inserted into a joint groove (groove portion) 15 formed between outer wall panels (building boards) 14 and 14 for a house, and the water-stopping property of the joint portion is used. And the design of the opening part of the joint groove 15 is maintained. In the mounting state in which the pedestal 3 is in contact with the bottom surface 16 of the joint groove 15, the fin portions 5 to 7 are curved and are in elastic contact with the inner side wall (inner surface) 17 of the joint groove 15, and water-stopping is ensured. Become.
[0020]
Now, as shown in FIG. 6, when the joint material 1 is inserted into the joint groove 15a having the relatively wide joint width W2, the base 3 is left attached. At this time, the fin portions 5 to 7 are curved and elastically contact the inner wall 17 in the curved state. However, in this attached state, the tip of the upper fin portion 5 is substantially flush with the outer surface of the outer wall panel 14. Since the inner wall 17 of the ditches 15 is hardly exposed, it is in an attached state with high water-stopping and good appearance.
[0021]
In addition, as shown in FIG. 7, the joint material 1 may be inserted in a state of being inclined with respect to the joint groove 15 (state indicated by a solid line in FIG. 7) at the time of attachment. Is set to be larger than the width L2 of the core material, the second support portion 12 is in a curved state with the tip of one side (left side in the figure) contacting the inner wall 17. At this time, a force that tends to be straight acts on the tip of the second support portion 12, and the joint material 1 moves in the direction of the arrow in FIG. A state indicated by a chain line). Therefore, the joint material 1 does not need to be attached to the joint groove 15 while being tilted, and it is difficult for the seal portion by the fin portions 5 to 7 to be biased, and a high water-stopping property is ensured.
[0022]
On the other hand, as shown in FIG. 8, when the joint material 1 is inserted into the joint groove 15 b having a relatively narrow joint width W <b> 1, the base 3 is separated from the joint material body 2 at the connection portion 13. And in the fitting state of the joint material 1 with respect to the joint groove 15b, since the fin parts 5-7 are largely curved, the height dimension of the joint material main body 2 becomes large. For this reason, the tip of the upper fin portion 5 is substantially flush with the outer surface of the outer wall panel 14, and water-stopping and appearance are ensured even with a narrow joint width W1.
[0023]
Therefore, in this embodiment, the following effects can be obtained.
(1) A structure in which a base 3 is provided on the joint material 1, and when the joint width is wide, the base 3 is fitted into the joint groove 15 and when the joint width is narrow, the base 3 is separated from the joint material body 2 and used. did. Therefore, even if the same joint material 1 is commonly used for joint grooves 15a and 15b having different joint widths, the inner wall 17 of the joint grooves 15a and 15b is hardly exposed in the attached state, and water is not exposed to the joint grooves 15a. , 15b becomes difficult to enter and water stoppage can be secured. In this attached state, the tip of the upper fin portion 5 and the upper surface of the outer wall panel 14 are substantially flush with each other, so that the appearance is good.
[0024]
(2) Since the width L1 of the second support portion 12 is set to be larger than the width L2 of the core material, even if the joint material 1 is inserted into the joint groove 15 in a tilted state, the second support portion 12 is curved and the joint groove 15 The joint material 1 is almost standing in the joint groove 15 by the deformation action of the second support portion 12 contacting the inner wall 17 returning to the original straight state. Therefore, the joint material 1 does not need to be attached to the joint groove 15 while being tilted, and it is difficult for the seal portion by the fin portions 5 to 7 to be biased, and a high water-stopping property can be secured.
[0025]

[0032]
As shown in FIG. 13, notches 22 may be formed on both sides of the column part 10 of the pedestal 3 to make a part of the column part 10 thin. In this case, the pedestal 3 can be easily cut by the notch 22, and a large number of joint widths can be handled with one component. Further, the number of connecting portions 13 is not limited to three, but may be two as shown in the figure, or may be one or four or more.
[0033]
-As shown in FIG. 14, the upper fin part 5 of the joint material main body 2 is good also as a substantially flat plate shape. Further, the bent portion 8 that connects the upper fin portion 5 and the intermediate fin portion 6 may be omitted.
[0034]
-As shown in FIG. 15, you may make the base 3 hollow and may form the space part 23 inside. In this case, since the pedestal 3 can be easily deformed in the vertical and horizontal directions, the height and inclination angle in the vertical direction can be easily changed by the deformation action of the pedestal 3 even when the joint material 1 remains attached. To do. Therefore, it becomes possible to cope with the change in joint width and the inclination of the joint groove 15 by this change, and versatility increases.
[0035]
-As shown in FIG. 16, you may provide the fin part 24 in the both right and left sides of the 1st support part 11. As shown in FIG. Moreover, it is good also as a structure which provides the fin part 25 in the 2nd support part 12 with the 1st support part 11, and both the 1st support part 11 and the 2nd support part 12 have a fin part.
[0036]
-You may combine the characteristic structure of the joint material 1 of embodiment and FIGS. For example, you may combine the structure (refer FIG. 10) which made the pillar part 10 thin, and the structure (refer FIG. 12) which provides the fin part 21 in the base 3. FIG. Similarly, the configuration shown in FIG. 12 may be combined with the configuration in which the space portion 23 is provided in the base 3 (see FIG. 15).
[0037]
The design layer 9 of the joint material 1 may have a shape having a textured surface on the surface 9a as shown in FIG.
-The material of the joint material is not limited to rubber, and synthetic resin or metal may be used.
