Description

本発明は、構造物の接着方法及び接着構造に関し、特に、構造用接着剤を用いた構造物の接着方法及び接着構造に関する。 The present invention relates to a structure bonding method and structure, and more particularly to a structure bonding method and structure using a structural adhesive.

構造用接着剤は、車両、電気機器、船舶、建築・土木、宇宙産業分野等の幅広い分野で利用されている。「構造用接着剤」とは、JIS(Japanese Industrial Standards:日本工業規格)K6800によれば、「長期間大きな荷重に耐える信頼できる接着剤」と定義されている。 Structural adhesives are used in a wide range of fields such as vehicles, electrical equipment, ships, construction/civil engineering, and the space industry. A "structural adhesive" is defined as a "reliable adhesive capable of withstanding large loads for a long period of time" according to JIS (Japanese Industrial Standards) K6800.

例えば、船舶の艤装品の取り付けには、常温硬化性の構造用接着剤が用いられることが多い。かかる構造用接着剤を用いることにより、艤装品を取り付ける部分が薄い鋼板の場合であっても、溶接歪のような熱変形を生じることがなく、溶接の代替手段の一つとして利用されている。 For example, cold curing structural adhesives are often used to attach ship fittings. By using such a structural adhesive, even if the part to which the equipment is attached is a thin steel plate, thermal deformation such as welding distortion does not occur, and it is used as one of the alternatives to welding. .

ところで、構造用接着剤は、接着対象の構造物が保持できるようになるまで少なくとも10分以上の時間を要することから、作業員が手で押さえておくか、治具を用いて構造物を固定しておく必要がある。 By the way, the structural adhesive requires at least 10 minutes or more until the structure to be adhered can be held. need to keep

また、特許文献1には、加熱硬化型の構造用接着剤を用いて部材と部材とを接着接合する方法であって、塗布した構造用接着剤に沿うようにしてその外側に常温硬化型の瞬間接着剤を塗布し、その状態で両者の仮接合を行った後、構造用接着剤の加熱による硬化処理を行うことが開示されている。 In addition, Patent Document 1 discloses a method of adhesively joining members to each other using a heat-curable structural adhesive, in which a room-temperature-curable adhesive is applied to the outside along the applied structural adhesive. It is disclosed that an instant adhesive is applied, the two are temporarily joined in that state, and then the structural adhesive is cured by heating.

上述したように、作業員の補助や治具で構造用接着剤が硬化するまで保持することは作業時間に無駄が多く、作業コストも増大することとなる。また、例えば、船舶の艤装品(レセプタクル、照明、電線支持具、機器設置台等)のように、暴露部に取り付けられる構造物では、接着部に一定の強度が求められる。 As described above, holding the structural adhesive with the assistance of workers or with a jig until the structural adhesive is cured wastes a lot of working time and increases the working cost. In addition, for example, in a structure attached to an exposed portion, such as ship fittings (receptacle, lighting, wire support, equipment installation table, etc.), the adhesive portion is required to have a certain strength.

上述した特許文献1に記載された発明では、構造用接着剤の外側に瞬間接着剤が配置されていることから、構造用接着剤の端部は接着する部材間に挟まれた位置に存在することとなる。一般に、構造用接着剤は硬化時に収縮することから、その端部でひび割れが生じやすい。かかるひび割れは、接着部の強度低下を引き起こす原因となる。 In the invention described in Patent Document 1 mentioned above, since the instant adhesive is arranged outside the structural adhesive, the end of the structural adhesive exists at a position sandwiched between the members to be adhered. It will happen. Structural adhesives generally shrink when cured and are prone to cracking at their edges. Such cracks cause a decrease in the strength of the bonded portion.

本発明の第一実施形態に係る構造物1の接着方法は、被接着部2の表面に構造物1を接着する方法であって、構造用接着剤3及び仮止用接着剤4の塗布面積を算出する塗布面積算出工程Step1と、構造用接着剤3及び仮止用接着剤4の塗布面積を合算した面積以上の大きさを備えた接着面11aを有する接着部11の形状を特定する形状特定工程Step2と、接着面11aに構造用接着剤3及び仮止用接着剤4を塗布する塗布工程Step3と、接着面11aを被接着部2の表面に押し付けて接着する接着工程Step4と、を含み、接着工程Step4で構造用接着剤3が接着面11aの外周からはみ出すように、塗布工程Step3で構造用接着剤3を塗布している。 The bonding method of the structure 1 according to the first embodiment of the present invention is a method of bonding the structure 1 to the surface of the adherend part 2, and the application area of the structural adhesive 3 and the temporary fixing adhesive 4 A shape that specifies the shape of the adhesive portion 11 having an adhesive surface 11a having a size greater than or equal to the total area of the application area calculation step Step 1 of the structural adhesive 3 and the temporary fixing adhesive 4 A specific process Step2, an application process Step3 of applying the structural adhesive 3 and the temporary fixing adhesive 4 to the bonding surface 11a, and a bonding process Step4 of pressing and bonding the bonding surface 11a to the surface of the bonded part 2 In addition, the structural adhesive 3 is applied in the coating step Step 3 so that the structural adhesive 3 protrudes from the outer periphery of the bonding surface 11a in the bonding step Step 4.

構造物1は、例えば、レセプタクル、照明、電線支持具、機器設置台等の艤装品であるが、これらに限定されるものではない。また、被接着部2は、例えば、船舶の床面、壁面、天井面等のように平面を形成する暴露部である。また、構造物1は、例えば、図3(C)に示したように、本体部1aと、本体部1aを支持する支持部材1bと、備えている。したがって、構造物1は、支持部材1bを被接着部2に固定してから、支持部材1bに本体部1aが取り付けられる。 The structure 1 is, for example, a receptacle, a lighting fixture, an electric wire support, an equipment installation stand, or other equipment, but is not limited to these. Also, the adherend portion 2 is an exposed portion that forms a flat surface, such as a floor surface, a wall surface, a ceiling surface, or the like of a ship, for example. Further, the structure 1 includes, for example, a body portion 1a and a support member 1b that supports the body portion 1a, as shown in FIG. 3(C). Therefore, in the structure 1, after the support member 1b is fixed to the adherend portion 2, the main body portion 1a is attached to the support member 1b.

塗布面積算出工程Step1は、構造用接着剤3の塗布面積を算出する第一算出工程Step11と、仮止用接着剤4の塗布面積を算出する第二算出工程Step12と、を含んでいる。なお、第一算出工程Step11と第二算出工程Step12の順序はどちらを先に処理してもよいし、同時に処理してもよい。 The application area calculation step Step 1 includes a first calculation step Step 11 for calculating the application area of the structural adhesive 3 and a second calculation step Step 12 for calculating the application area of the temporary fixing adhesive 4 . As for the order of the first calculation step Step11 and the second calculation step Step12, whichever may be processed first, or may be processed at the same time.

構造用接着剤3は、例えば、金属の接着に適した第二世代アクリル系の構造用接着剤であるが、構造用接着剤3は構造物1及び被接着部2の素材によって適宜選択することができる。また、構造物1が船舶の艤装品である場合には、構造用接着剤3は常温硬化型であることが好ましい。 The structural adhesive 3 is, for example, a second-generation acrylic structural adhesive suitable for bonding metals. can be done. Further, when the structure 1 is a ship's outfitting, the structural adhesive 3 is preferably of a room temperature curing type.

構造用接着剤3は、硬化後に構造物1(本体部1a及び支持部材1b)を保持する部材であることから、少なくとも構造物1の重量を保持可能な強度が必要である。したがって、構造用接着剤3の塗布面積は、構造物1(本体部1a及び支持部材1b)の重量に基づいて算出される。なお、支持部材1bが本体部1aと比較して十分に軽量である場合には、構造用接着剤3の塗布面積は、本体部1aの重量に基づいて算出してもよい。 Since the structural adhesive 3 is a member that holds the structure 1 (the main body 1a and the support member 1b) after curing, it must have strength enough to hold the weight of the structure 1 at least. Therefore, the application area of the structural adhesive 3 is calculated based on the weight of the structure 1 (body portion 1a and support member 1b). If the support member 1b is sufficiently lighter than the body portion 1a, the application area of the structural adhesive 3 may be calculated based on the weight of the body portion 1a.

仮止用接着剤4は、例えば、シアノアクリレートを主成分とする瞬間接着剤であるが、これに限定されるものではない。また、支持部材1bの重量や素材によっては、仮止用接着剤4は両面テープであってもよい。 The temporary adhesive 4 is, for example, an instant adhesive containing cyanoacrylate as a main component, but is not limited to this. Further, depending on the weight and material of the support member 1b, the temporary fixing adhesive 4 may be a double-sided tape.

仮止用接着剤4は、構造用接着剤3が硬化するまで支持部材1bを保持可能な強度を有していればよく、本体部1aを保持可能なほど大きな強度は必要がない。したがって、仮止用接着剤4の塗布面積は、支持部材1bの重量に基づいて算出される。 The temporary fixing adhesive 4 only needs to have strength enough to hold the support member 1b until the structural adhesive 3 is cured, and does not need to have strength large enough to hold the main body portion 1a. Therefore, the application area of the temporary fixing adhesive 4 is calculated based on the weight of the support member 1b.

形状特定工程Step2は、構造物1の接着部11、すなわち、本実施形態では支持部材1bの接着部11の形状を特定する工程である。接着部11は、平面を形成する被接着部2に対して密着可能な平板形状を有している。接着部11の外形は、例えば、図2(A)に示したように、角部にR形状を有する四角形状であるが、これに限定されるものではない。接着部11は、円形状、楕円形状、多角形状等の外形を有してしてもよい。 The shape specifying step Step 2 is a step of specifying the shape of the bonding portion 11 of the structure 1, that is, the bonding portion 11 of the support member 1b in this embodiment. The bonding portion 11 has a flat plate shape that can be in close contact with the bonded portion 2 forming a flat surface. The outer shape of the bonding portion 11 is, for example, a quadrangular shape having rounded corners as shown in FIG. 2A, but is not limited to this. The bonding portion 11 may have an outer shape such as a circular shape, an elliptical shape, or a polygonal shape.

かかる形状特定工程Step2は、例えば、図2(A)に示したように、接着部11が構造用接着剤3を塗布する主接着面113と仮止用接着剤4を塗布する補助接着面114とを有し、接着面11aの中心部付近に補助接着面114を配置し、その外周に主接着面113を配置するように、接着部11の形状を特定する工程である。 In this shape specifying step Step 2, for example, as shown in FIG. , and specifies the shape of the bonding portion 11 so that the auxiliary bonding surface 114 is arranged near the center of the bonding surface 11a and the main bonding surface 113 is arranged on the outer periphery thereof.

主接着面113の面積は、塗布面積算出工程Step1の第一算出工程Step11により算出された構造用接着剤3の塗布面積以上の大きさに特定される。また、補助接着面114は、塗布面積算出工程Step1の第二算出工程Step12により算出された仮止用接着剤4の塗布面積以上の大きさに特定される。 The area of the main adhesive surface 113 is specified to be larger than the application area of the structural adhesive 3 calculated in the first calculation step Step11 of the application area calculation step Step1. Further, the auxiliary adhesive surface 114 is specified to have a size equal to or larger than the application area of the temporary fixing adhesive 4 calculated in the second calculation step Step 12 of the application area calculation step Step 1 .

このように、形状特定工程Step2では、接着部11の外形の形状を特定した後、塗布面積算出工程Step1で算出された構造用接着剤3及び仮止用接着剤4の塗布面積に基づいて接着部11の最終形状が特定される。 As described above, in the shape specifying step Step 2, after specifying the shape of the outer shape of the bonding portion 11, bonding is performed based on the application areas of the structural adhesive 3 and the temporary fixing adhesive 4 calculated in the application area calculation step Step 1. The final shape of portion 11 is specified.

塗布工程Step3は、主接着面113に構造用接着剤3を塗布する第一塗布工程Step31と、補助接着面114に仮止用接着剤4を塗布する第二塗布工程Step32と、を含んでいる。なお、説明の便宜上、図2(B)において、構造用接着剤3を濃い灰色で図示し、仮止用接着剤4を薄い灰色で図示してある。 The application step Step 3 includes a first application step Step 31 of applying the structural adhesive 3 to the main adhesive surface 113 and a second application step Step 32 of applying the temporary adhesive 4 to the auxiliary adhesive surface 114. . For convenience of explanation, in FIG. 2B, the structural adhesive 3 is shown in dark gray, and the temporary fixing adhesive 4 is shown in light gray.

かかる塗布工程Step3では、例えば、図2(B)に示したように、構造用接着剤3及び仮止用接着剤4が塗布される。なお、第一塗布工程Step31及び第二塗布工程Step32の順序は図1に示した順序に限定されるものではなく、第二塗布工程Step32を先に処理してもよい。 In the application step Step 3, for example, as shown in FIG. 2B, the structural adhesive 3 and the temporary fixing adhesive 4 are applied. The order of the first coating step Step31 and the second coating step Step32 is not limited to the order shown in FIG. 1, and the second coating step Step32 may be processed first.

また、図2(B)に示したように、構造用接着剤3及び仮止用接着剤4は、複数の列を形成するように直線状に盛られた状態で塗布される。このように構造用接着剤3を所定の間隔を空けて直線状に並べて塗布することにより、接着時に構造用接着剤3を主接着面113に満遍なく行き渡らせることができるだけでなく、展延時の空気の混入を抑制することができる。構造用接着剤3に空気が混入すると接着強度が低下してしまうため、空気の混入を抑制することが好ましい。 Further, as shown in FIG. 2B, the structural adhesive 3 and the temporary fixing adhesive 4 are applied in a state of being piled up linearly so as to form a plurality of rows. By applying the structural adhesive 3 in a straight line at predetermined intervals in this way, it is possible not only to spread the structural adhesive 3 evenly over the main bonding surface 113 during bonding, but also to prevent the spread of the structural adhesive 3 from the air. contamination can be suppressed. If air is mixed into the structural adhesive 3, the adhesive strength is lowered, so it is preferable to suppress the mixing of air.

また、仮止用接着剤4を直線状に塗布した部分の両側に塗布される構造用接着剤3は、仮止用接着剤4と略同一直線上に配置されていることが好ましい。かかる配置により、構造用接着剤3の展延時に仮止用接着剤4を外部に漏らさずに封じ込むことができる。 Moreover, it is preferable that the structural adhesive 3 applied to both sides of the portion where the temporary fixing adhesive 4 is linearly applied is arranged substantially on the same straight line as the temporary fixing adhesive 4 . With such arrangement, the temporary fixing adhesive 4 can be enclosed without leaking to the outside when the structural adhesive 3 is spread.

また、接着面11aの周縁部に塗布される構造用接着剤3は、被接着部2に接着部11を押し付けた際に接着面11aの外周からはみ出すことができる分量が塗布される。例えば、図2(B)に示した構造用接着剤3において、左から順に一列目~五列目と定義するものとする。 Further, the structural adhesive 3 applied to the peripheral portion of the bonding surface 11a is applied in an amount that protrudes from the outer periphery of the bonding surface 11a when the bonding portion 11 is pressed against the adhered portion 2. As shown in FIG. For example, in the structural adhesive 3 shown in FIG. 2(B), the first to fifth columns are defined in order from the left.

一列目の構造用接着剤3は、接着時に展延することによって接着面11aの図の左側及び上下両側にはみ出すように分量が調整されている。二列目~四列目の構造用接着剤3は、接着時に展延することによって接着面11aの図の上下両側にはみ出すように分量が調整されている。五列目の構造用接着剤3は、接着時に展延することによって接着面11aの図の右側及び上下両側にはみ出すように分量が調整されている。 The amount of structural adhesive 3 in the first row is adjusted so that it spreads at the time of adhesion so that it protrudes to the left side and both upper and lower sides of the adhesive surface 11a in the drawing. The amounts of the structural adhesives 3 in the second to fourth rows are adjusted so that they protrude from the upper and lower sides of the adhesive surface 11a in the figure by spreading during adhesion. The amount of the structural adhesive 3 in the fifth row is adjusted so that it protrudes to the right side and both upper and lower sides of the adhesive surface 11a as it spreads during adhesion.

接着工程Step4は、図2(B)に示したように、接着部11を被接着部2の表面に押し付けて、塗布された構造用接着剤3及び仮止用接着剤4を展延させて、主接着面113に構造用接着剤3を満遍なく行き渡らせるとともに、接着面11aの外周からはみ出させた状態に保持する工程である。このとき、補助接着面114には仮止用接着剤4が満遍なく行き渡っていることから、作業員の補助や治具を用いることなく、構造物1(支持部材1b)を図2(B)に示した状態のまま保持することができる。 In the bonding step Step 4, as shown in FIG. 2B, the bonding portion 11 is pressed against the surface of the bonded portion 2 to spread the applied structural adhesive 3 and temporary fixing adhesive 4. 1, the structural adhesive 3 is evenly spread over the main adhesive surface 113 and is held in a state where it protrudes from the outer circumference of the adhesive surface 11a. At this time, since the temporary fixing adhesive 4 is evenly spread over the auxiliary adhesive surface 114, the structure 1 (supporting member 1b) can be assembled as shown in FIG. It can be kept as shown.

構造用接着剤3の硬化前は、図3(A)に示したように、構造用接着剤3は接着部11の周縁部から盛り上がった状態(外に凸な状態)になっている。その後、時間の経過とともに構造用接着剤3が硬化すると、構造用接着剤3は収縮し、図3(B)に示したように、接着部11の周縁部からはみ出した部分が窪んだ状態(内に凸な状態)に変形することとなる。 Before the structural adhesive 3 is cured, as shown in FIG. 3A, the structural adhesive 3 is in a raised state (outwardly convex state) from the peripheral edge of the bonding portion 11 . After that, when the structural adhesive 3 hardens over time, the structural adhesive 3 shrinks, and as shown in FIG. Inwardly convex state).

このように、接着部11の周縁部からはみ出した部分で構造用接着剤3を収縮させることにより、接着面11aと被接着部2の表面との間に生じるひび割れを抑制することができる。したがって、接着部11の強度低下を抑制することができ、接着後の接着部11の強度を保持することができる。 By shrinking the structural adhesive 3 in the portion protruding from the peripheral edge of the bonding portion 11 in this manner, cracks occurring between the bonding surface 11a and the surface of the bonded portion 2 can be suppressed. Therefore, it is possible to suppress a decrease in the strength of the bonding portion 11 and maintain the strength of the bonding portion 11 after bonding.

構造用接着剤3が硬化した後、図3(C)に示したように、支持部材1bに本体部1aを取り付ける。なお、図示した本体部1a及び支持部材1bの構成は、単なる例示であり、図示した構成に限定されるものではない。 After the structural adhesive 3 is cured, the body portion 1a is attached to the support member 1b as shown in FIG. 3(C). The illustrated configurations of the main body portion 1a and the support member 1b are merely examples, and are not limited to the illustrated configurations.

上述した第一実施形態に係る構造物1の接着方法によれば、構造用接着剤3及び仮止用接着剤4の塗布面積を合算した面積以上の大きさを備えた接着面11aを有し、接着時に接着面11aの外周から構造用接着剤3がはみ出すように構成された接着部11を備えた構造物1の接着構造が構成される。 According to the bonding method of the structure 1 according to the first embodiment described above, the bonding surface 11a having a size equal to or greater than the total area of the structural adhesive 3 and the temporary fixing adhesive 4 is applied. , the bonding structure of the structure 1 having the bonding portion 11 configured so that the structural adhesive 3 protrudes from the outer periphery of the bonding surface 11a during bonding is configured.

次に、塗布工程Step3の変形例について、図4(A)及び図4(B)を参照しつつ説明する。ここで、図4は、塗布工程の変形例を示す図であり、(A)は第一変形例、(B)は第二変形例、である。 Next, a modification of the coating step Step 3 will be described with reference to FIGS. 4(A) and 4(B). Here, FIG. 4 is a diagram showing a modified example of the coating process, (A) is the first modified example, and (B) is the second modified example.

図4(A)に示した第一変形例は、仮止用接着剤4を塗布する位置を左から四列目の位置に変更したものである。このように、仮止用接着剤4を塗布する位置は、必ずしも接着面11aの中心部である必要はなく、中心部に近い領域(例えば、二列目や四列目の位置)であってもよい。かかる位置に仮止用接着剤4を塗布した場合であっても、接着工程Step4において、構造用接着剤3で仮止用接着剤4を内部に封じ込むことができる。 In the first modification shown in FIG. 4(A), the position for applying the temporary fixing adhesive 4 is changed to the fourth row position from the left. Thus, the position where the temporary fixing adhesive 4 is applied does not necessarily have to be the center of the adhesive surface 11a, but a region near the center (for example, the position of the second or fourth row) good too. Even when the temporary fixing adhesive 4 is applied to such a position, the temporary fixing adhesive 4 can be sealed inside with the structural adhesive 3 in the adhesion process Step 4 .

換言すれば、仮止用接着剤4を塗布する位置は、一列目や五列目に配置することは好ましくない。この場合、接着工程Step4において、仮止用接着剤4が構造用接着剤3の展延によって接着面11aの外に押し出されてしまい、構造物1の仮止めに必要な強度を保持することができないことが予測される。 In other words, it is not preferable to apply the temporary fixing adhesive 4 to the first row or the fifth row. In this case, in the bonding step Step 4, the temporary fixing adhesive 4 is pushed out of the bonding surface 11a by the spread of the structural adhesive 3, and the strength necessary for temporarily fixing the structure 1 cannot be maintained. expected to be impossible.

図4(B)に示した第二変形例は、構造用接着剤3及び仮止用接着剤4を斜めに塗布したものである。接着工程Step4において、仮止用接着剤4を封じ込みつつ構造用接着剤3を接着面11aの外周にはみ出させることができれば、構造用接着剤3及び仮止用接着剤4を塗布する方向は任意に設定することができる。 In the second modification shown in FIG. 4B, the structural adhesive 3 and the temporary fixing adhesive 4 are applied obliquely. In the adhesion process Step 4, if the structural adhesive 3 can be protruded to the outer periphery of the adhesion surface 11a while enclosing the temporary fixing adhesive 4, the direction in which the structural adhesive 3 and the temporary fixing adhesive 4 are applied is Can be set arbitrarily.

次に、本発明の第二実施形態に係る構造物の接着方法について、図5(A)~図6(F)を参照しつつ説明する。ここで、図5は、本発明の第二実施形態に係る構造物の接着方法を示す説明図であり、(A)は形状特定工程及び塗布工程、(B)は接着工程、を示している。 Next, a structure bonding method according to a second embodiment of the present invention will be described with reference to FIGS. 5(A) to 6(F). Here, FIG. 5 is an explanatory view showing the bonding method of the structure according to the second embodiment of the present invention, (A) shows the shape specifying step and coating step, and (B) shows the bonding step. .

第二実施形態に係る構造物1の接着方法の基本的な流れは図1に示した第一実施形態と同一である。この第二実施形態では、形状特定工程Step2における構造物1の接着部11の形状並びに塗布工程Step3にける構造用接着剤3及び仮止用接着剤4の塗布方法が異なっている。 The basic flow of the bonding method for the structure 1 according to the second embodiment is the same as that of the first embodiment shown in FIG. In this second embodiment, the shape of the bonding portion 11 of the structure 1 in the shape specifying step Step2 and the method of applying the structural adhesive 3 and the temporary fixing adhesive 4 in the applying step Step3 are different.

第二実施形態における形状特定工程Step2は、接着部11が構造用接着剤3を塗布する主接着面113と仮止用接着剤4を塗布する補助接着面114とを有し、主接着面113の外周に補助接着面114を形成する複数のタブ11bを配置するように、接着部11の形状を特定する工程である。 In the shape specifying step Step 2 in the second embodiment, the adhesive portion 11 has a main adhesive surface 113 to which the structural adhesive 3 is applied and an auxiliary adhesive surface 114 to which the temporary fixing adhesive 4 is applied. In this step, the shape of the bonding portion 11 is specified so that a plurality of tabs 11b forming the auxiliary bonding surface 114 are arranged on the outer periphery of the bonding portion 11. As shown in FIG.

具体的には、図5(A)に示したように、形状特定工程Step2において、主接着面113は略矩形形状に形成され、その四つの角部に略矩形のタブ11bが形成される。そして、塗布工程Step3において、主接着面113には、複数の列を形成するように構造用接着剤3が直線状に塗布される。また、補助接着面114を構成するタブ11bには、その中心部に仮止用接着剤4が塗布される。 Specifically, as shown in FIG. 5A, in the shape specifying step Step 2, the main adhesive surface 113 is formed in a substantially rectangular shape, and substantially rectangular tabs 11b are formed at the four corners thereof. Then, in the application step Step 3 , the structural adhesive 3 is linearly applied to the main adhesive surface 113 so as to form a plurality of rows. Further, the temporary fixing adhesive 4 is applied to the central portion of the tab 11b constituting the auxiliary adhesive surface 114. As shown in FIG.

また、構造用接着剤3は、接着工程Step4において、図5(B)に示したように、接着面11a(主接着面113)の外周から構造用接着剤3がはみ出すように塗布される。本実施形態において、タブ11b(補助接着面114)は支持部材1bの仮止めに用いられる部分であり、構造用接着剤3の硬化後に構造物1を保持可能な強度は要求されない部分である。 Further, in the bonding process Step 4, the structural adhesive 3 is applied so that the structural adhesive 3 protrudes from the outer circumference of the bonding surface 11a (main bonding surface 113), as shown in FIG. 5B. In this embodiment, the tab 11b (auxiliary adhesive surface 114) is a portion used for temporarily fixing the support member 1b, and is a portion that does not require strength to hold the structure 1 after the structural adhesive 3 is cured.

構造物1の保持に必要な強度は、主接着面113によって担保されることから、構造用接着剤3は主接着面113からはみ出していれば十分である。本実施形態では、構造用接着剤3の一部はタブ11bの下に位置していることから、構造用接着剤3の硬化時に収縮してひび割れが生じる可能性がある。しかしながら、上述したように、タブ11bは構造物1を保持するための強度を担保する部分ではないことから、強度保持に与える影響は少ない。 Since the strength required to hold the structure 1 is secured by the main adhesive surface 113, it is sufficient for the structural adhesive 3 to protrude from the main adhesive surface 113. FIG. In this embodiment, since a portion of the structural adhesive 3 is located under the tab 11b, it may shrink and crack when the structural adhesive 3 cures. However, as described above, since the tab 11b is not a portion that ensures the strength for holding the structure 1, it has little effect on strength maintenance.

次に、第二実施形態における形状特定工程Step2及び塗布工程Step3の変形例について、図6(A)~図6(F)を参照しつつ説明する。ここで、図6は、形状特定工程及び塗布工程の変形例を示す図であり、(A)は第一変形例、(B)は第二変形例、(C)は第三変形例、(D)は第四変形例、(E)は第五変形例、(F)第六変形例、である。 Next, modified examples of the shape identifying step Step 2 and the coating step Step 3 in the second embodiment will be described with reference to FIGS. 6(A) to 6(F).

Although not shown, tabs 11b may be formed at the corners of the main adhesive surface 113 so as to extend vertically in the figure. Also, although not shown, the tabs 11b may be formed so that some of the tabs 11b extend in the horizontal direction of the figure and the remaining tabs 11b extend in the vertical direction of the figure.

FIG. Although not shown, the shape of the tab 11b may be circular, polygonal, or the like. It should be noted that the tabs 11b do not necessarily have to be formed at the center of each side as long as they are arranged in a well-balanced manner in the vertical and horizontal directions.

図6(D)に示した第四変形例は、主接着面113の図の左右両側の辺に二つずつタブ11bを形成したものである。本変形例は、図6(B)に示したタブ11bを左右両側の辺に沿って中央部寄りに位置を変更したものということもできる。図示しないが、主接着面113の図の上下両側の辺に二つずつタブ11bを形成してもよい。また、各辺に形成されるタブ11bの個数は三つ以上であってもよい。 In the fourth modification shown in FIG. 6(D), two tabs 11b are formed on each of the left and right sides of the main adhesive surface 113 in the figure. In this modification, the tab 11b shown in FIG. 6(B) can be said to be shifted along the left and right sides toward the central portion. Although not shown, two tabs 11b may be formed on each of the upper and lower sides of the main adhesive surface 113 in the figure. Also, the number of tabs 11b formed on each side may be three or more.

図6(E)に示した第五変形例は、主接着面113の角部に図の左右方向及び上下方向に延設するように計八つのタブ11bを形成したものである。また、図6(F)に示した第六変形例は、図6(E)に示したタブ11bを各辺に沿って中央部寄りに位置を変更したものである。 In the fifth modification shown in FIG. 6(E), a total of eight tabs 11b are formed at the corners of the main adhesive surface 113 so as to extend in the left-right direction and the up-down direction of the figure. In the sixth modification shown in FIG. 6(F), the position of the tab 11b shown in FIG. 6(E) is changed toward the central portion along each side.

上述したように、タブ11bの個数及び配置は、仮止用接着剤4の塗布面積、支持部材1bの重量や重心の位置、構造物1を接着する場所の環境等の条件によって任意に設定することができる。 As described above, the number and arrangement of the tabs 11b are arbitrarily set according to conditions such as the application area of the temporary fixing adhesive 4, the weight and the position of the center of gravity of the support member 1b, and the environment of the place where the structure 1 is adhered. be able to.
