特開平１０－１５２９１５号公報JP-A-10-152915

部材間の隙間に適切に樹脂が充填されていない場合、または、隙間において充填量にムラがある場合、建築物の気密性が十分に確保できない場合がある。 If the gaps between members are not properly filled with the resin, or if the filling amount is uneven in the gaps, the airtightness of the building may not be sufficiently ensured.

（１）上記課題を解決する建築物の建築方法は、建築物を建築する建築方法であって、建築部材を組み立てる組立工程と、封止樹脂の噴霧によって、組み立てられた前記建築部材の間の隙間を埋めるように樹脂層を形成する樹脂層形成工程と、を含み、前記封止樹脂の色は、前記隙間を構成する前記建築部材の色と異なる。 (1) A building construction method for solving the above problems is a construction method for constructing a building, comprising an assembly step of assembling building members, and spraying a sealing resin to separate the assembled building members. and a resin layer forming step of forming a resin layer so as to fill the gap, wherein the color of the sealing resin is different from the color of the building member forming the gap.

この構成によれば、建築部材の色と異なる封止樹脂の噴霧によって建築部材の間の隙間を埋める。これによって、気密性が高い樹脂層を形成し易い。このため、建築物の気密性を向上できる。 According to this configuration, the gaps between the building members are filled by spraying the sealing resin different in color from the building members. This makes it easy to form a highly airtight resin layer. Therefore, the airtightness of the building can be improved.

（２）上記（１）の建築物の建築方法において、前記樹脂層形成工程において、前記隙間を構成する前記建築部材の色が前記樹脂層を介して透けて見える状態がなくなるまで、または、前記樹脂層を介して見える前記建築部材の色が元の色よりも薄くなるまで、前記封止樹脂を噴霧する。 (2) In the building construction method of (1) above, in the resin layer forming step, until the color of the building member forming the gap is no longer visible through the resin layer, or The sealing resin is sprayed until the color of the building member seen through the resin layer becomes lighter than the original color.

Further, when pinholes are formed in the resin layer, it is difficult to ensure airtightness. In this respect, according to the above configuration, extremely thin portions or pinholes can be reduced in the resin layer. As a result, the long-term airtightness of the building can be improved.

According to this configuration, the state of formation of the resin layer can be confirmed based on the sample color of the sample, so variations in the thickness of the resin layer caused by operators can be reduced.

（４）上記（１）～（３）のいずれか１つの建築物の建築方法において、前記封止樹脂の色は、前記隙間を構成する前記建築部材の色に対する補色である。
この構成によれば、視認によって樹脂層と建築部材とを区別し易くできる。これによって、樹脂層の厚みが十分であるか否かを判定し易い。 (4) In the building construction method according to any one of (1) to (3) above, the color of the sealing resin is a complementary color to the color of the building member forming the gap.
According to this configuration, the resin layer and the building member can be easily distinguished visually. This makes it easy to determine whether the thickness of the resin layer is sufficient.

（５）上記（１）～（４）のいずれか１つの建築物の建築方法において、前記封止樹脂の噴霧前、前記隙間を構成する前記建築部材を、前記封止樹脂の色と異なる色に変色させる。封止樹脂の色を建築部材の色と異なるようにする場合、封止樹脂の色として選択できる選択幅は、建築部材の色によって制限される。この点、上記構成によれば、樹脂層の色を自由に選択できるようになる。 (5) In the building construction method according to any one of (1) to (4) above, before spraying the sealing resin, the building member forming the gap is coated with a color different from the color of the sealing resin. discolor to When making the color of the sealing resin different from the color of the building member, the range of choices for the color of the sealing resin is limited by the color of the building member. In this respect, according to the above configuration, the color of the resin layer can be freely selected.

（６）上記（１）～（５）のいずれか１つの建築物の建築方法において、前記隙間をシール部材で封止した後、前記シール部材を含む範囲に前記封止樹脂を噴霧する。この構成によれば、建築物の気密性を向上できる。 (6) In the method of constructing a building according to any one of (1) to (5) above, after the gap is sealed with a sealing member, the sealing resin is sprayed onto a range including the sealing member. According to this configuration, the airtightness of the building can be improved.

（７）上記（１）～（６）のいずれか１つの建築物の建築方法において、前記封止樹脂は、変性シリコーン樹脂、または、エラストマ樹脂である。この構成によれば、伸縮性に優れた樹脂層を形成できる。これによって、建築物の揺れおよび軋みによって、樹脂層の破れを抑制できる。 (7) In the building construction method according to any one of (1) to (6) above, the sealing resin is a modified silicone resin or an elastomer resin. According to this configuration, a resin layer having excellent stretchability can be formed. As a result, it is possible to suppress breakage of the resin layer due to shaking and creaking of the building.

（８）課題を解決する建築物は、基礎と、前記基礎に直接または間接的に固定されて互いに結合される建築部材と、前記建築部材の間の隙間を埋めるように設けられる樹脂層と、を備え、前記樹脂層は、変性シリコーン樹脂またはエラストマ樹脂により構成され、前記樹脂層の色は、前記隙間を構成する前記建築部材の色と異なる色を有する。この構成によれば、建築物の気密性を向上できる。 (8) A building that solves the problem comprises a foundation, building members directly or indirectly fixed to the foundation and connected to each other, a resin layer provided to fill gaps between the building members, wherein the resin layer is made of a modified silicone resin or an elastomer resin, and the color of the resin layer is different from the color of the building member forming the gap.

図１に示されるように、建築物１は、建築物１内の室内と建築物１の外の室外とを繋ぐ隙間Ｓを有する。隙間Ｓは、図１の円で囲まれる部分にある。
図２～図５を参照して、建築物１の隙間Ｓの例を挙げる。図２～図５は、隙間Ｓについて従来の封止方法を示す図である。図２に示されるように、床２を構成する床板２ａの間には隙間Ｓがある。床板２ａの間の隙間Ｓは、室外と室内とを繋ぐ通気路を構成する。２つの床板２ａの間の隙間Ｓは、シール部材１７で封止される。例えば、シール部材１７は、アルミテープである。 As shown in FIG. 1, the building 1 has a gap S connecting the interior of the building 1 and the exterior of the building 1 . The gap S is in the portion surrounded by the circle in FIG.
An example of the gap S of the building 1 will be given with reference to FIGS. 2 to 5. FIG. 2 to 5 are diagrams showing a conventional sealing method for the gap S. FIG. As shown in FIG. 2, there is a gap S between the floorboards 2a forming the floor 2. As shown in FIG. A gap S between the floor plates 2a constitutes an air passage connecting the outside and the inside of the room. A gap S between the two floor plates 2a is sealed with a sealing member 17. As shown in FIG. For example, the sealing member 17 is an aluminum tape.

給水管１０ａと床板２ａとの間および排水管１０ｂと床板２ａとの間には、隙間Ｓがある。給水管１０ａと床板２ａとの間の隙間Ｓ、および、排水管１０ｂと床板２ａとの間の隙間Ｓは、室外と室内とを繋ぐ通気路を構成する。このような配管の隙間Ｓは、コーキング材１８によって埋められる。 There is a gap S between the water supply pipe 10a and the floor plate 2a and between the drain pipe 10b and the floor plate 2a. A gap S between the water supply pipe 10a and the floor plate 2a and a gap S between the drain pipe 10b and the floor plate 2a form an air passage connecting the outside and the inside. The gap S between such pipes is filled with the caulking material 18 .

床板２ａと壁板２ｂとの間には隙間Ｓがある。床板２ａと壁板２ｂとの間の隙間Ｓは、室外と室内とを繋ぐ通気路を構成する。床板２ａと壁板２ｂとの間の隙間Ｓは、シール部材１７で封止される。 There is a gap S between the floorboard 2a and the wallboard 2b. A gap S between the floor plate 2a and the wall plate 2b constitutes an air passage connecting the outside and the inside. A gap S between the floor plate 2a and the wall plate 2b is sealed with a seal member 17. As shown in FIG.

また、図３に示されるように、柱３の周辺には隙間Ｓがある。柱３は、室外から室内に渡るように設けられるため、柱３の周辺には、室外と室内とを繋ぐ隙間Ｓがある。具体的には、土台に立てられる柱３と床板２ａとの間には隙間Ｓが生じる。床板２ａは、気密シート４で覆われる。一方、柱３と床板２ａとの間には、隙間Ｓがある。 In addition, as shown in FIG. 3, there is a gap S around the pillar 3 . Since the pillar 3 is provided so as to extend from the outdoor to the indoor, there is a gap S around the pillar 3 connecting the outdoor and the indoor. Specifically, a gap S is created between the pillar 3 erected on the base and the floor board 2a. The floorboard 2a is covered with an airtight sheet 4. - 特許庁On the other hand, there is a gap S between the pillar 3 and the floorboard 2a.

図４に示されるように、梁５と壁枠７との間には第１断熱部材８ａが詰められる。第１断熱部材８ａは、第１断熱部材８ａの弾性によって梁５に接触する。梁５において、第１断熱部材８ａが接触する部分において、梁５と第１断熱部材８ａとの間には隙間Ｓがある。梁５には、梁５の長手方向に沿うように第２断熱部材８ｂが取り付けられる。第１断熱部材８ａと第２断熱部材８ｂとの間の隙間Ｓは、梁５と第１断熱部材８ａとの間の隙間Ｓと繋がる。このような隙間Ｓと隙間Ｓとの繋がりは、室外と室内とを繋ぐ通気路を構成する。このようなことから、第１断熱部材８ａと第２断熱部材８ｂとの間の隙間Ｓは、シール部材１７で封止される。 As shown in FIG. 4, the space between the beam 5 and the wall frame 7 is filled with a first heat insulating member 8a. The first heat insulating member 8a contacts the beam 5 due to the elasticity of the first heat insulating member 8a. In the beam 5, there is a gap S between the beam 5 and the first heat insulating member 8a at the portion where the first heat insulating member 8a contacts. A second heat insulating member 8 b is attached to the beam 5 along the longitudinal direction of the beam 5 . A gap S between the first heat insulating member 8a and the second heat insulating member 8b is connected to a gap S between the beam 5 and the first heat insulating member 8a. The connection between the gaps S and the gaps S constitutes an air passage connecting the outside and the inside of the room. Therefore, the gap S between the first heat insulating member 8a and the second heat insulating member 8b is sealed with the seal member 17. As shown in FIG.

図５に示されるように、梁５には、第３断熱部材８ｃが設けられる。第３断熱部材８ｃは、梁５に沿うように設けられる。梁５と桁６との接続部分において、第３断熱部材８ｃは、第３断熱部材８ｃの端面が桁６に突き当たるように設けられる。梁５と桁６との接続部分には、梁５と桁６との間に隙間Ｓ（図示省略）がある。また、第３断熱部材８ｃと桁６との間にも隙間Ｓがある。梁５と桁６との間に隙間Ｓは、第３断熱部材８ｃと桁６との間の隙間と繋がる。このような隙間Ｓと隙間Ｓとの繋がりは、室外と室内とを繋ぐ通気路を構成する。このようなことから、梁５と桁６との接続部分は、カバー９によって覆われる。カバー９は、複数の分割体９ａによって構成される。分割体９ａは、第３断熱部材８ｃに密着するように設けられる。梁５と桁６との接続部分において、複数の分割体９ａを組み合わせることによって、梁５と桁６との接続部分を覆う。カバー９と桁６との間の隙間Ｓは、シール部材１７で封止される。 As shown in FIG. 5, the beam 5 is provided with a third heat insulating member 8c. The third heat insulating member 8 c is provided along the beam 5 . The third heat insulating member 8 c is provided at the connecting portion between the beam 5 and the girder 6 so that the end surface of the third heat insulating member 8 c abuts the girder 6 . A gap S (not shown) exists between the beam 5 and the girder 6 at the connecting portion between the beam 5 and the girder 6 . There is also a gap S between the third heat insulating member 8c and the girder 6. As shown in FIG. A gap S between the beam 5 and the girder 6 connects with a gap between the third heat insulating member 8 c and the girder 6 . The connection between the gaps S and the gaps S constitutes an air passage connecting the outside and the inside of the room. For this reason, the connecting portion between the beam 5 and the girder 6 is covered with the cover 9 . The cover 9 is composed of a plurality of divided bodies 9a. The divided body 9a is provided so as to be in close contact with the third heat insulating member 8c. The connecting portion between the beam 5 and the girder 6 is covered by combining a plurality of divided bodies 9a. A gap S between the cover 9 and the girder 6 is sealed with a seal member 17 .

隙間Ｓは、建築物１の気密性を低下させる。隙間Ｓを介して外気が入ることによって建築物１の室内環境が低下する。具体的には、外気の侵入によって、室内の空調環境が低下し、または、空調効率の低下が生じる。建築物１の室内環境の向上のため、建築物１では、気密ライン（図１の破線）が設けられる。気密ラインは、室内を囲むように設けられる。建築物１において、気密ラインに沿うように気密シート４が設けられ、隙間Ｓは、様々な方法で埋められる。例えば、隙間Ｓは、コーキング材によって埋められる。隙間Ｓは、発泡ウレタンの吹き付けによって埋められる。隙間Ｓは、カバー９によって覆われてもよい。 The gap S reduces the airtightness of the building 1 . The indoor environment of the building 1 deteriorates due to the outside air entering through the gap S. Specifically, intrusion of outside air deteriorates the air-conditioned environment in the room, or causes a decrease in air-conditioning efficiency. In order to improve the indoor environment of the building 1, the building 1 is provided with airtight lines (broken lines in FIG. 1). The airtight line is provided so as to surround the room. In a building 1, an airtight sheet 4 is provided along an airtight line, and gaps S are filled by various methods. For example, the gap S is filled with caulking material. The gap S is filled by spraying urethane foam. The gap S may be covered with the cover 9 .

In another example, board 31 is white. In another example, the color of board 31 is brown.

封止樹脂は、変性シリコーン樹脂、または、エラストマ樹脂である。
変性シリコーン樹脂は、変性シリコーンを含む樹脂である。変性シリコーン樹脂は、噴霧可能な程度の粘性を有する。好ましくは、変性シリコーン樹脂は、室温で硬化する。変性シリコーン樹脂は、変性シリコーンの他に、他の低粘度ポリマーを含んでもよい。変性シリコーン樹脂は、有機溶剤を含んでもよい。低粘度ポリマーおよび有機溶剤によって変性シリコーン樹脂の粘度は調整される。 The sealing resin is modified silicone resin or elastomer resin.

封止樹脂は、半透明、または、不透明である。封止樹脂の色は、隙間Ｓを構成する建築部材１５の色と異なる。目視によって、色の違いが認識できる程度に、封止樹脂の色は、建築部材１５の色と異なる。具体的には、建築部材１５の色についてマンセルカラーシステムの基本１０色から色相を特定した場合、色相環の円周方向において、封止樹脂の色相が建築部材１５の色相から２以上離れた色相をとるように、封止樹脂の色が決定される。例えば、建築部材１５の色相が赤の場合は、封止樹脂の色相が、黄色以外かつ赤紫以外の色相であることが好ましい。具体的には、建築部材１５の色相が赤の場合は、封止樹脂の色相は、黄色、黄緑、緑、青緑、青、紫青、紫から選択される。さらに、明度を考慮して、色を選択されてもよい。建築部材１５の明度が低い場合、封止樹脂は、明度が高い色が選択される。例えば、建築部材１５が黒に近い色である場合、封止樹脂は、白に近い色のものが選択される。 The sealing resin is translucent or opaque. The color of the sealing resin is different from the color of the building member 15 forming the gap S. The color of the sealing resin is different from the color of the building member 15 to such an extent that the color difference can be visually recognized. Specifically, when the hue of the building member 15 is specified from the 10 basic colors of the Munsell color system, the hue of the sealing resin is a hue that is separated from the hue of the building member 15 by two or more in the circumferential direction of the color wheel. The color of the sealing resin is determined so that For example, when the hue of the building member 15 is red, the hue of the sealing resin is preferably a hue other than yellow and reddish purple. Specifically, when the hue of the building member 15 is red, the hue of the sealing resin is selected from yellow, yellowish green, green, bluish green, blue, purple blue, and purple. In addition, the colors may be selected with lightness in mind. When the brightness of the building member 15 is low, a color with high brightness is selected for the sealing resin. For example, if the building member 15 has a color close to black, the sealing resin having a color close to white is selected.

好ましくは、封止樹脂の色は、隙間Ｓを構成する建築部材１５の色に対する補色である。封止樹脂の色は、染料または顔料によって着色される。封止樹脂の着色は、建築部材１５の色と異なる色に変色するために、工事現場で行われてもよい。 Preferably, the color of the sealing resin is complementary to the color of the building member 15 forming the gap S. The color of the sealing resin is colored with a dye or pigment. The coloring of the sealing resin may be carried out at the construction site in order to change the color to a color different from that of the building member 15 .

封止樹脂を噴霧する前に、隙間Ｓを構成する建築部材１５を、封止樹脂の色と異なる色に変色させてもよい。例えば、塗料を建築部材１５に塗布すること、または、塗料を建築部材１５に吹き付けることによって、建築部材１５を変色させる。建築部材１５をシール材で覆うことによって変色させてもよい。変色後の建築部材１５の色は、封止樹脂の色の補色であることが好ましい。封止樹脂の色が白である場合、建築部材１５は、黒に変色される。 Before spraying the sealing resin, the building member 15 forming the gap S may be discolored to a color different from that of the sealing resin. For example, the building member 15 is discolored by applying paint to the building member 15 or by spraying paint onto the building member 15 . The color may be changed by covering the building member 15 with a sealing material. The color of the building member 15 after discoloration is preferably complementary to the color of the sealing resin. When the color of the sealing resin is white, the building member 15 is discolored to black.

また、色が異なる複数の建築部材１５が組み合っている部分に隙間がある場合、その部分の全体を覆うように樹脂層２０を形成する。この場合、封止樹脂を噴霧する前に、その部分全体を、封止樹脂の色と異なる色に変色させてもよい。具体的には、色が異なる複数の建築部材１５が組み合っている部分全体を、封止樹脂の色の補色となるように変色させてもよい。変色は、噴霧する封止樹脂の色と異なる色の封止樹脂を使うことによって、行われてもよい。 Moreover, if there is a gap in a portion where a plurality of building members 15 of different colors are combined, the resin layer 20 is formed so as to cover the entire portion. In this case, the entire portion may be discolored to a color different from the color of the sealing resin before the sealing resin is sprayed. Specifically, the entire portion where a plurality of building members 15 of different colors are combined may be discolored so as to be complementary to the color of the sealing resin. Color change may be achieved by using a different color encapsulation resin than the color of the encapsulation resin to be sprayed.

以上の建築物１の建築方法によれば、次のような建築物１が構成される。
建築物１は、基礎１１と、建築部材１５と、樹脂層２０とを備える。建築部材１５は、基礎１１に直接または間接的に固定されて互いに結合される。建築部材１５によって、建築物本体１２および屋根１３が構成される。樹脂層２０は、建築部材１５の間の隙間Ｓを埋めるように設けられる。樹脂層２０は、変性シリコーン樹脂またはエラストマ樹脂により構成される。樹脂層２０の色は、隙間Ｓを構成する建築部材１５の色と異なる色を有する。 According to the construction method of the building 1 described above, the building 1 is configured as follows.
A building 1 includes a foundation 11 , a building member 15 and a resin layer 20 . The building members 15 are directly or indirectly fixed to the foundation 11 and connected to each other. The building member 15 constitutes the building body 12 and the roof 13 . The resin layer 20 is provided so as to fill the gap S between the building members 15 . The resin layer 20 is made of modified silicone resin or elastomer resin. The color of the resin layer 20 is different from the color of the building member 15 forming the gap S.

本実施形態の作用を説明する。
従来、建築物１の気密性の確保のため、天井裏または壁に発泡ウレタンの吹き付けが行われている。しかしながら、発泡ウレタンを対象領域にムラなく吹き付けることが難しい。また、吹き付けられた発泡ウレタンの層において、隙間Ｓを見つけることも難しい。具体的には、発泡ウレタンは、凸凹構造を有し、発泡ウレタンの内部に、建築物１の内外を繋ぐ細い通路が形成される場合がある。この通路の開口端が、発泡ウレタンの凸部の横にある場合には、外部から、目視で、このような隙間Ｓの開口端を発見でき難い。したがって、発泡ウレタンの吹き付けでは、隙間Ｓの封止漏れを発見することが困難であり、建築物１の気密性を向上させることは難しい。また、対象領域を気密シート４で覆うこともあるが、複雑な構造を有する部分において気密シート４で完全に覆うことは難しい。２つの気密シート４のつなぎ目に隙間Ｓができる可能性もある。一方、コーキング材の使用によれば、建築物１の気密性を確保し易い。しかし、コーキング材の塗布は、多くの労力を有し、作業性に劣る。 The operation of this embodiment will be described.
Conventionally, in order to ensure the airtightness of the building 1, foamed urethane is sprayed on the ceiling space or walls. However, it is difficult to evenly spray the urethane foam onto the target area. It is also difficult to find the gap S in the sprayed urethane foam layer. Specifically, urethane foam has an uneven structure, and narrow passages connecting the inside and outside of the building 1 may be formed inside the urethane foam. If the open end of the passage is located next to the urethane foam protrusion, it is difficult to find the open end of the gap S visually from the outside. Therefore, it is difficult to find sealing leaks in the gap S by spraying urethane foam, and it is difficult to improve the airtightness of the building 1 . Moreover, although the target area may be covered with the airtight sheet 4, it is difficult to completely cover the part having a complicated structure with the airtight sheet 4. FIG. There is also a possibility that a gap S is formed at the joint of the two airtight sheets 4 . On the other hand, the use of the caulking material facilitates securing the airtightness of the building 1 . However, the application of the caulking material requires a lot of labor and is poor in workability.

この点、本実施形態では、封止樹脂の噴霧によって樹脂層２０を形成する。これによって、効率的に樹脂層２０を形成できる。樹脂層２０は、樹脂層２０が設けられる対象領域の隙間Ｓを構成する建築部材１５と異なる色を有する。このため、目視によって、樹脂層２０を建築部材１５と区別できる。噴霧の場合、樹脂層２０は、封止樹脂の液滴が重なって形成される。液滴が互いに繋がっていない場合、または、液滴によって形成される層が薄い場合、または、液滴に形成される層にピンホールが生じる場合、建築部材１５が樹脂層２０を介して透けて見える。このため、作業者は、対象領域において、噴霧されていない部分を目視で発見し易い。また、作業者は、噴霧が足りない部分を目視で確認できる。このようにして、建築物１の気密性が高めることができる樹脂層２０を形成できる。 In this regard, in the present embodiment, the resin layer 20 is formed by spraying the sealing resin. Thereby, the resin layer 20 can be efficiently formed. The resin layer 20 has a different color from the building member 15 forming the gap S in the target area where the resin layer 20 is provided. Therefore, the resin layer 20 can be visually distinguished from the building member 15 . In the case of spraying, the resin layer 20 is formed by overlapping droplets of sealing resin. If the droplets are not connected to each other, or if the layer formed by the droplets is thin, or if pinholes are formed in the layer formed by the droplets, the building member 15 can be seen through the resin layer 20. appear. Therefore, the operator can easily find the non-sprayed portion of the target area by visual inspection. In addition, the operator can visually confirm the portion where the spray is insufficient. In this way, the resin layer 20 that can improve the airtightness of the building 1 can be formed.

この構成によれば、建築部材１５の色と異なる封止樹脂の噴霧によって建築部材１５の間の隙間Ｓを埋める。これによって、気密性が高い樹脂層２０を形成し易い。このため、建築物１の気密性を向上できる。 According to this configuration, the gap S between the building members 15 is filled by spraying the sealing resin different in color from the building members 15 . This makes it easy to form the resin layer 20 with high airtightness. Therefore, the airtightness of the building 1 can be improved.

（２）樹脂層形成工程において、隙間Ｓを構成する建築部材１５の色が樹脂層２０を介して透けて見える状態がなくなるまで封止樹脂を噴霧する。または、樹脂層形成工程において、樹脂層２０を介して見える建築部材１５の色が元の色よりも薄くなるまで、封止樹脂を噴霧する。樹脂層２０において、極端に薄い部分は、経時劣化で穴になり易く、長期的な気密性が確保し難い。また、樹脂層２０にピンホールが形成されると、気密性が確保し難い。この点、上記構成によれば、樹脂層２０が極端に薄くなっている部分および樹脂層２０のピンホールを視認によって確認し易いため、樹脂層２０において、極端に薄い部分またはピンホールを少なくできる。これによって、建築物１において、長期的な気密性を向上できる。 (2) In the resin layer forming step, the sealing resin is sprayed until the color of the building member 15 forming the gap S is no longer visible through the resin layer 20 . Alternatively, in the resin layer forming step, the sealing resin is sprayed until the color of the building member 15 seen through the resin layer 20 becomes lighter than the original color. An extremely thin portion of the resin layer 20 is likely to become a hole due to deterioration over time, making it difficult to ensure long-term airtightness. Further, if pinholes are formed in the resin layer 20, it is difficult to ensure airtightness. In this respect, according to the above configuration, it is easy to visually confirm the portion where the resin layer 20 is extremely thin and the pinhole in the resin layer 20, so that the extremely thin portion or the pinhole in the resin layer 20 can be reduced. .

According to this configuration, the resin layer 20 and the building member 15 can be easily distinguished visually. This makes it easy to determine whether the thickness of the resin layer 20 is sufficient.

（５）封止樹脂の噴霧前、隙間Ｓを構成する建築部材１５を、封止樹脂の色と異なる色に変色させる。封止樹脂の色を建築部材１５の色と異なるようにする場合、封止樹脂の色として選択できる選択幅は、建築部材１５の色によって制限される。この点、上記構成によれば、樹脂層２０の色を自由に選択できるようになる。 (5) Before the sealing resin is sprayed, the building member 15 forming the gap S is discolored to a color different from that of the sealing resin. When making the color of the sealing resin different from the color of the building member 15 , the selection range of the color of the sealing resin is limited by the color of the building member 15 . In this respect, according to the above configuration, the color of the resin layer 20 can be freely selected.

（６）隙間Ｓをシール部材１７で封止した後、シール部材１７を含む範囲に封止樹脂を噴霧する。この構成によれば、建築物１の気密性を向上できる。この場合、シール部材１７は、封止樹脂と異なる色であることが好ましい。 (6) After the gap S is sealed with the sealing member 17, the sealing resin is sprayed to the range including the sealing member 17; According to this configuration, the airtightness of the building 1 can be improved.

According to this configuration, the resin layer 20 having excellent stretchability can be formed. As a result, it is possible to prevent the resin layer 20 from breaking due to shaking and creaking of the building 1 .

（８）建築物１は、基礎１１と、基礎１１に直接または間接的に固定されて互いに結合される建築部材１５と、建築部材１５の間の隙間Ｓを埋めるように設けられる樹脂層２０と、を備える。樹脂層２０は、変性シリコーン樹脂またはエラストマ樹脂により構成される。樹脂層２０の色は、隙間Ｓを構成する建築部材１５の色と異なる色を有する。この構成によれば、建築物１の気密性を向上できる。 (8) The building 1 comprises a foundation 11, building members 15 directly or indirectly fixed to the foundation 11 and connected to each other, and a resin layer 20 provided to fill a gap S between the building members 15. , provided. The resin layer 20 is made of modified silicone resin or elastomer resin. The color of the resin layer 20 is different from the color of the building member 15 forming the gap S.

The color of the resin layer 20 is different from the color of the building member 15 and the color of the sealing member 17 forming the gap S. According to this configuration, the airtightness of the building can be improved.

（１０）上記（９）のように、シール部材１７を覆う樹脂層２０の色は、隙間Ｓを構成する建築部材１５の色に対する補色であることが好ましい。この構成によれば、視認によって樹脂層２０と建築部材１５とを区別し易くできる。これによって、建築物１の建築中および建築後において、樹脂層２０の厚みが十分であるか否か、または、ピンホールが形成されていないか、を判定し易い。一例では、樹脂層２０の色は、建築部材１５の色の補色であり、かつ、シール部材１７の色と異なる。 (10) As in (9) above, the color of the resin layer 20 covering the sealing member 17 is preferably complementary to the color of the building member 15 forming the gap S. According to this configuration, the resin layer 20 and the building member 15 can be easily distinguished visually.
