Description
【０００１】
【発明の属する技術分野】
この発明は、建物の外装板の継目に用いる目地材に関し、特に、継目に充填するコーキング材のバックアップとして使用するものである。
【０００２】
【従来の技術】
従来、この種の目地材は、コーキング材との接着を防ぐ必要があるので、コーキング材が触れる面に、コーキング材と相容性のない合成樹脂製のテープを貼り付ける方式を採っている。しかし、このテープ貼付方式の場合には、将来、コーキング材の詰め替え工事などの際にテープが剥れ易く、耐久性に乏しいという欠点がある。そこで、本発明者は、このテープ貼付方式に代わるコーティング方式を既に提案（特願２００２−１４５５９８号）した。
【０００３】
【発明が解決しようとする課題】
ところが、前記のコーティング方式の場合には、コーティングする合成樹脂が、コーキング材との相容性のないものである為、目地材の芯材である、例えば、金属板との接着力も弱くて、長期間経過すると、コーティングが剥れるおそれがある。
【０００４】
本発明は、このような点に鑑み、目地芯材の表面に形成した、コーキング材との相容性のない合成樹脂製の表面材が、芯材から剥れにくく、耐久性に富んだ目地材を提供するにある。
【０００５】
【課題を解決するための手段】
本発明の目地材の技術的手段は、金属板製の芯材の表面に、中間材を介して表面材が付着されている目地材であって、中間材は、芯材及び表面材に対して接着力を有し、表面材は、コーキング材との相容性のない合成樹脂製であり、これら中間材及び表面材は、押出インサート成形法により、芯材の端縁を含む表裏両面を完全に巻き込むようにして一体的に付着させられていることにある。
【０００６】
また、中間材には、エチレン酢酸ビニル共重合体ケン化物や合成ゴム系ホットメルト接着剤を用いるのがよい。
【０００７】
【発明の実施の形態】
本発明の目地材の実施の形態を、図面の実施例に基づいて説明する。図１は使用状態で、目地材１０は外装板１、１の継目２の背面側に取付けられる。実際の工事の施工手順は、柱３などの表に目地材１０を取付け、目地材１０の突出部１１を挟むように外装板１、１を配置し、その継目２の溝内にコーキング材４を充填する。ただし、このコーキング材４は外装板１、１の小口面５、５とだけ接着し、目地材１０の突出部１１の外面には接着しないようにする必要がある。突出部１１に接着していると、コーキング材４の自由度が小さくなるので、割れが発生し易くなる。
【０００８】
図２に目地材１０の拡大断面が示されている。目地材１０は、その中央に、継目の幅に合わせた突出部１１を有し、その両側又は片側にフランジ部１２が連設された断面形状を持った長尺体である。通常、この目地材１０は平板からの折曲げ加工によって製造される。なお、突出部１１やフランジ部１２の詳細な形状は、自由に設計可能である。
【０００９】
目地材１０の素材は、芯材１３と、表面材１４と、中間材１５との3層構造である。芯材１３には、鋼板やアルミニウム板などの金属板を用いる。表面材１４は、コーキング材との相容性がないことが必要で、通常は、オレフィン系の合成樹脂、例えば、低密度ポリエチレン樹脂やポリプロピレン樹脂などが用いられる。中間材１５は、芯材１３や表面材１４に対して、充分な接着力を有することが必要で、例えば、エチレン酢酸ビニル共重合体ケン化物や合成ゴム系ホットメルト接着剤などが適する。
【００１０】
表面材１４や中間材１５の、芯材１３に対する付着方法は、折曲げ加工前の平板状の芯材１３に対して、押出インサート成形法により、前記の合成樹脂材を押出しながら芯材に一体的に付着させる方法を採る。また、この際の表面材１４や中間材１５の厚さは自由であるが、通常は、表面材１４は、１０〜１００ミクロン、好ましくは２０〜５０ミクロン程度が適し、中間材１５は、３〜３０ミクロン、好ましくは、５〜１０ミクロン程度が適する。
【００１１】
芯材１３の表面に、表面材１４と中間材１５とが付着されるが、その際には、芯材１３と表面材１４との間に中間材１５が介装されていることが必要である。また、中間材１５及び表面材１４は、芯材１３の表裏両面を完全に巻き込むように、全面的に付着される。従って、目地材１０の取扱い時や、施工時などに端縁１６の切り口で、手を怪我することがなく、その上、芯材１３が露出していないので、錆の発生を防止できる。
【００１３】
本発明は、前記の実施例に限定されるものではなく、特許請求の範囲の記載の範囲内で自由に変形実施可能である。特に、目地材の突出部１１やフランジ部１２の形状、更には、芯材１３、表面材１４及び中間材１５の材質や厚さなどは自由である。
【００１４】
【発明の効果】
本発明の目地材は、その突出部の表面に、コーキング材との相容性のない合成樹脂製の表面材が付着されているので、継目に充填したコーキング材が目地材と接着することがなく、コーキング材の割れを防止できる。また、表面材は、接着力を有する中間材によって芯材に付着されているので、表面材の付着力が強くて、長期間の使用によっても、芯材から剥がれることがなく、耐久性に富む。また、中間材と表面材とが、芯材の全表面を覆っているので、芯材が金属板でも結露や錆の発生を防止でき、また、端縁で手を怪我することがない。
【００１５】
請求項２のものは、中間材に、エチレン酢酸ビニル共重合体ケン化物や合成ゴム系ホットメルト接着剤が用いられているので、接着力が強くて、表面材を剥れないように強固に保持できる上に、硬化後には、その粘着力が悪くなるので、取扱いに都合が良い。

Fill. However, it is necessary that the caulking material 4 is bonded only to the facets 5 and 5 of the exterior plates 1 and 1 and not to be bonded to the outer surface of the protruding portion 11 of the joint material 10. If the protrusion 11 is bonded, the degree of freedom of the caulking material 4 becomes small, and cracks are likely to occur.
[0008]
FIG. 2 shows an enlarged cross section of the joint material 10. The joint material 10 is a long body having a cross-sectional shape in which a projecting portion 11 corresponding to the width of the seam is provided at the center and a flange portion 12 is continuously provided on both sides or one side thereof. Usually, the joint material 10 is manufactured by bending from a flat plate. In addition, the detailed shape of the protrusion part 11 and the flange part 12 can be designed freely.
[0009]
The material of the joint material 10 has a three-layer structure of a core material 13, a surface material 14, and an intermediate material 15. The core material 13, using a metal plate such as steel plate or aluminum plate. The surface material 14 needs to be incompatible with the caulking material, and usually an olefin-based synthetic resin, for example, a low density polyethylene resin or a polypropylene resin is used. The intermediate material 15 is required to have a sufficient adhesive force with respect to the core material 13 and the surface material 14, and for example, an ethylene vinyl acetate copolymer saponified product or a synthetic rubber-based hot melt adhesive is suitable.
[0010]
The surface material 14 and intermediate material 15, attachment methods for the core material 13, relative to bending before the plate-like core member 13, by an extrusion insert molding method, integrally with the core member while extruding a synthetic resin material Adhering method is adopted . In this case, the thickness of the surface material 14 and the intermediate material 15 is arbitrary, but usually the surface material 14 is 10 to 100 microns, preferably about 20 to 50 microns, and the intermediate material 15 is 3 ˜30 microns, preferably about 5 to 10 microns is suitable.
[0011]
The surface of the core material 13, but the surface member 14 and the intermediate member 15 is attached, in that case, necessary and this intermediate member 15 is interposed between the core 13 and the surface member 14 It is . Further, the intermediate material 15 and the surface material 14 are attached to the entire surface so that both the front and back surfaces of the core material 13 are completely wound. Therefore, the hand is not injured at the cut edge of the edge 16 when handling the joint material 10 or during construction, and the core material 13 is not exposed, so that the occurrence of rust can be prevented .
[0013]
The present invention is not limited to the above-described embodiments, and can be freely modified within the scope of the claims. In particular, the shape of the protruding portion 11 and the flange portion 12 of the joint member, further, the core material 13, etc. the material and thickness Sana of surface material 14 and intermediate material 15 is free.
[0014]
【The invention's effect】
In the joint material of the present invention, since a surface material made of synthetic resin that is incompatible with the caulking material is attached to the surface of the protruding portion, the caulking material filled in the seam may adhere to the joint material. In addition, cracking of the caulking material can be prevented. In addition, since the surface material is attached to the core material by an intermediate material having an adhesive force, the surface material has a strong adhesive force, and does not peel off from the core material even after long-term use, and has high durability. . Moreover, since the intermediate material and the surface material cover the entire surface of the core material, even if the core material is a metal plate, it is possible to prevent the occurrence of condensation and rust, and there is no injury to the hand at the edge.
[0015]
Since the saponified ethylene-vinyl acetate copolymer and the synthetic rubber-based hot melt adhesive are used for the intermediate material in the second aspect, the adhesive strength is strong and the surface material is strong enough not to peel off. In addition to being able to hold, the adhesive strength is poor after curing, which is convenient for handling.
