【発明の詳細な説明】
この発明は、組立建物の外壁パネルなどのパネル相互に
生ずる継目部分の隙間を水密にシールする防水工法に関
するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a waterproofing method for watertightly sealing gaps between joints of panels such as exterior wall panels of prefabricated buildings.
従来のこの種の防水工法は、第５図に示すように、複合
パネル１，１の継目部分の表面に形成した溝２Ｖｃ不定
形のシーリング材３を充填するものであった。In the conventional waterproofing method of this type, as shown in FIG. 5, grooves 2Vc formed on the surface of the joint portion of the composite panels 1, 1 are filled with an irregularly shaped sealing material 3.
このような場合の欠点は、シーリング材３と溝２におけ
る小口との接着面積Ａが少ないため、シーリング材３の
充填を雑に行うと十分な接着が得られず、漏水事故の起
きる原因となることである。The disadvantage in such a case is that the adhesion area A between the sealant 3 and the edge of the groove 2 is small, so if the sealant 3 is filled sloppily, sufficient adhesion may not be obtained and water leakage may occur. That's true.
同様に接着面Ａ′が小さいため、パネル材１ａと表面材
１ｂとの間に侵入し、表面材１ｂが剥離するなどの原因
となる。Similarly, since the adhesive surface A' is small, it may enter between the panel material 1a and the surface material 1b, causing the surface material 1b to peel off.
また施工に際して技術を要することも欠点となっている
。Another disadvantage is that the construction requires special skills.
また接着面を増すために、パネル相互にわたる目地をテ
ーパー状に形成すると、目地中に比べて深さが小さくな
ることから、不定形のシーリング材の充填が上記溝２の
場合よりも困難となり、シーリング材も接着性のある軟
かい素材が要求される。Furthermore, if the joints between the panels are formed into a tapered shape in order to increase the adhesive surface, the depth will be smaller than the depth of the joints, making it more difficult to fill the irregularly shaped sealant than in the case of the groove 2, The sealant also requires a soft material with adhesive properties.
この接着性のある軟かいシーリング材の多くは、硬化に
時間がかかり、また硬化時に収縮が生じ易く、目地部分

どの欠点がある。Many of these soft adhesive sealants take a long time to cure, tend to shrink during curing, and have drawbacks such as concave joints, making it difficult to finish them flush with the surface material.

ることなく、防水性能が一段と向上した組立建物におけ
る防水工法を提供せんとするものである。This invention solves the above-mentioned drawbacks of the conventional method by using thermoplastic urethane,
Ethylene vinyl acetate resin (EVA), polypropylene,
Thermoplastic resins such as polyethylene and or styrene-butadiene rubber (SBR), inbutylene isoprene (
A tape-shaped sealing material made of synthetic rubber such as IIR) is removed by thermo-compression bonding to the tapered joints, and the waterproof performance is further improved with a simple process and no special technology is required. The purpose is to provide an improved waterproofing method for prefabricated buildings.
以下この発明を第１〜４図により詳説する。This invention will be explained in detail below with reference to FIGS. 1 to 4.
建物の外壁を構成するパネル１０は、表面に防水性能を
有する石綿板１１が防水性の接着剤でコールドプレスし
である。The panel 10 constituting the outer wall of the building has a waterproof asbestos board 11 on its surface cold-pressed with a waterproof adhesive.
このパネル１０の石綿板１１の接続端の表面には、隣接
したパネルとによってパネル相互にわたる浅いＶ字型の
テーパー目地１２を形成するテーパー面１２ａが施しで
ある。The surface of the connection end of the asbestos board 11 of this panel 10 is provided with a tapered surface 12a that forms a shallow V-shaped tapered joint 12 extending between adjacent panels.
しかして、第１図に示すようにパネル１０の建込みが完

にプライマー１４を塗布して、テープ状の離型紙１！ｌ
貼着した定形シーリング材１６を第２図に示すようにあ
てがう。As shown in FIG.
Apply primer 14 to the tape-shaped release paper 1! l
The fixed shaped sealant 16 is applied as shown in FIG.
次に離型紙１５の上からアイロンのようなアプリケータ
ー１７を押しつけて、定形シーリング材１６を加熱（８
０〜１５０℃）し、テーバー目地１２に圧着したのち、
離型紙１５をはがして定形シーリング材１６を残す（第
３図参照）。Next, press an applicator 17 like an iron onto the release paper 15 to heat the shaped sealant 16 (8
0 to 150°C) and crimped to Taber joint 12,
The release paper 15 is peeled off, leaving the regular sealing material 16 (see FIG. 3).
この発明は上述のように、パネルの継目部分に形成した
テーパー目地に定形シーリング材を熱圧着して、継目を
シールするものであるから、下記の効果を有する。As described above, this invention has the following effects because it seals the joint by thermocompression bonding a regular sealing material to the tapered joint formed at the joint portion of the panel.
０）パネル表面にテーパー目地を形成して、そこに定形
シーリング材を熱圧着するため、接着面積Ａが従来の場
合よりも充分に確保でき、また目地が浅くとも全体にわ
たり均一に施工でき。0) Since tapered joints are formed on the panel surface and the regular sealing material is thermocompressed there, the bonding area A can be secured more fully than in the conventional case, and even if the joints are shallow, it can be applied uniformly over the entire surface.
不定形シーリング材によるときよシも性能が一段と向上
する。The performance of sealing with irregularly shaped sealing material is further improved.
（２）プライマーを塗布したので、表面材が石綿板であ
っても、確実に圧着でき、しかも離型紙の上から加熱押
圧するため施工が簡単で、熟練した技術も必要としない
。(2) Since the primer is applied, even if the surface material is an asbestos board, it can be reliably crimped, and since it is heated and pressed from above the release paper, construction is easy and does not require skilled techniques.
（３）ホントメルトタイプであるから、硬化するとすぐ
に防水機能を発揮する。(3) Since it is a true melt type, it exhibits its waterproof function as soon as it hardens.
（４）仕上げ工事がすぐ着手でき、工程の短縮に大きく
寄与する。(4) Finishing work can be started immediately, greatly contributing to shortening the process.
（５）硬化時の収縮がないから、目地が表面材と同一面
に仕上がり、仕上げ後には、パネルの目地が見えなくな
り、中型パネル工法の短所である目地の多さが解消され
る。(5) Since there is no shrinkage during curing, the joints are finished flush with the surface material, and the joints in the panel are no longer visible after finishing, eliminating the large number of joints that are a disadvantage of the medium-sized panel construction method.
などである。etc.
