Description

本発明は、建築物のエキスパンションジョイント部のクリアランスを覆いつつ、該クリアランスの大きさの変化に追随して伸縮するエキスパンションジョイントカバーに関するものである。 The present invention relates to an expansion joint cover that expands and contracts in accordance with a change in the size of the clearance while covering the clearance of the expansion joint portion of the building.

一般に、複雑な構造の建築物などでは、建築物自体を複数のブロックに分割すると共に、これらをエキスパンションジョイントによって接続して、地震や気温の変化、不同沈下などの影響を吸収することが多い。 In general, in a building having a complicated structure, the building itself is often divided into a plurality of blocks and connected by expansion joints to absorb the effects of an earthquake, temperature change, uneven settlement, and the like.

エキスパンションジョイントは、建築物のブロック同士をその相対変位に追従可能に接続する接続手法であり、建築物のブロック間に、相対変位を吸収可能な大きさのクリアランスを形成してエキスパンションジョイント部とすると共に、壁面などに露出するクリアランスをその両側部位の相対変位に追従可能なエキスパンションジョイントカバーで覆うようにしている。 An expansion joint is a connection method that connects blocks of a building so that they can follow their relative displacements, and forms a clearance large enough to absorb the relative displacements between the blocks of the building to form an expansion joint. At the same time, the clearance exposed on the wall surface is covered with an expansion joint cover that can follow the relative displacement of both sides.

エキスパンションジョイントカバーは、壁面などに露出するクリアランスの長さに合うよう、伸縮方向と交差する方向に連結して所望の長さに設定されることが多い（例えば、特許文献１）。 The expansion joint cover is often connected in a direction intersecting the expansion / contraction direction and set to a desired length so as to match the length of the clearance exposed on the wall surface or the like (for example, Patent Document 1).

図６に示すように、特許文献１のエキスパンションジョイントカバーは、エキスパンション材１０１の連結部分に同種素材のシート１０２を重ね、これらをプライマー及び接着剤を用いて接着することにより、シート１０２を介して、エキスパンション材１０１を連結したものである。 As shown in FIG. 6, in the expansion joint cover of Patent Document 1, a sheet 102 of the same material is superposed on a connecting portion of an expansion material 101, and these are bonded using a primer and an adhesive, thereby passing through the sheet 102. , The expansion material 101 is connected.

特開２００７－９４４９（段落００１５、図５）JP-A-2007-9449 (paragraph 0015, FIG. 5)

ところが、特許文献１のエキスパンションジョイントカバーは、連結部分にシート１０２を重ねて接着した構造であるので、その連結部分がシート１０２の全体と強固に一体化される。シート１０２の全体と一体化されることにより、連結部分の剛性が大きくなりやすく、エキスパンションジョイントカバーが伸縮する際、連結部分に力が集中して、シート１０２の剥がれなどの損傷や、全体のゆがみを生じるおそれがある。 However, since the expansion joint cover of Patent Document 1 has a structure in which the sheet 102 is laminated and adhered to the connecting portion, the connecting portion is firmly integrated with the entire sheet 102. By being integrated with the entire sheet 102, the rigidity of the connecting portion tends to increase, and when the expansion joint cover expands and contracts, the force concentrates on the connecting portion, causing damage such as peeling of the sheet 102 and overall distortion. May occur.

これに対し、特許文献１のエキスパンションジョイントカバーでは、エキスパンション材１０１の貫通孔１０３に芯材１０４を挿着して連結部分を補強しており、その分、エキスパンションジョイントカバーの構造が複雑になると共に、その連結に要する工数が多くなりやすい。 On the other hand, in the expansion joint cover of Patent Document 1, the core material 104 is inserted into the through hole 103 of the expansion material 101 to reinforce the connecting portion, and the structure of the expansion joint cover becomes complicated by that amount. , The man-hours required for the connection tend to increase.

本発明は、容易に連結するとこができると共に、伸縮による損傷を防止することのできるエキスパンションジョイントカバーの提供を目的とする。 An object of the present invention is to provide an expansion joint cover that can be easily connected and can prevent damage due to expansion and contraction.

上記目的を達成するために、本発明に係るエキスパンションジョイントカバーは、建築物のエキスパンションジョイント部のクリアランスを覆いつつ、このクリアランスの大きさの変化に追随して伸縮するものであり、伸縮可能な複数枚のカバー本体を伸縮方向と交差する方向に連結してなり、カバー本体の継目を跨ぐように連結材を重ねると共に、カバー本体及び連結材のうちのクリアランスを覆う部位に孔を形成してなるボタン孔に、抜け止めを挿入可能な抜け止め孔を先端に形成された軸部を頭部から突出させてなるプッシュボタンの軸部を挿入し、連結材を介して両側のカバー本体を連結したものである。 In order to achieve the above object, the expansion joint cover according to the present invention covers the clearance of the expansion joint portion of the building and expands and contracts according to the change in the size of the clearance. The cover bodies are connected in a direction intersecting the expansion and contraction direction, the connecting materials are stacked so as to straddle the joints of the cover bodies, and holes are formed in the parts of the cover body and the connecting materials that cover the clearance. The shaft part of the push button, which is formed by projecting the shaft part formed at the tip of the retaining hole into which the retaining hole can be inserted, is inserted into the button hole, and the cover bodies on both sides are connected via the connecting material. It is a thing.

上記構成によれば、カバー本体の継目を跨ぐように連結材を重ねて、それらのボタン孔にプッシュボタンを挿入するだけでカバー本体を連結することができるので、カバー本体に連結材を接着する構造と比較して、その連結に要する工数を少なくすることができる。つまり、接着による連結では、プライマーの塗布及び乾燥の後に接着剤を塗布し、この接着剤が固化するまで、専用の治具を用いて連結材を重ねた状態を維持する必要があるが、このような煩雑な工程を本発明の構成によって省略することができる。 According to the above configuration, the cover main body can be connected by simply stacking the connecting materials so as to straddle the seams of the cover main body and inserting a push button into those button holes, so that the connecting material is adhered to the cover main body. Compared with the structure, the man-hours required for the connection can be reduced. In other words, in the case of adhesive connection, it is necessary to apply the adhesive after applying the primer and drying, and to maintain the state in which the connecting materials are stacked using a special jig until the adhesive solidifies. Such a complicated process can be omitted by the configuration of the present invention.

さらに、エキスパンションジョイントカバーが伸縮する際に、プッシュボタンで留められている部位を除いて、カバー本体と連結材とのずれを許容できるので、接着構造と比較して、連結部分の剛性を小さくし、連結部分への力の集中を防止することができる。これにより、伸縮による損傷やゆがみを防止することができ、しかも、芯材などを用いて連結部分を補強する必要がない分、エキスパンションジョイントカバーの構造を簡単にすることができると共に、その連結に要する工数をより少なくすることができる。 Furthermore, when the expansion joint cover expands and contracts, it is possible to tolerate the displacement between the cover body and the connecting material except for the part that is fastened with the push button, so the rigidity of the connecting part is reduced compared to the adhesive structure. , It is possible to prevent the concentration of force on the connecting part. This makes it possible to prevent damage and distortion due to expansion and contraction, and because it is not necessary to reinforce the connecting part with a core material, the structure of the expansion joint cover can be simplified and the connection can be made. The number of man-hours required can be reduced.

また、カバー本体及び連結材にボタン孔を形成してプッシュボタンを挿入する代わりに、孔のないカバー本体及び連結材にピンを突き通すようにしてもよく、これにより、プッシュボタンを用いた上記の構成を採用することによる効果と同様の効果を奏することができる。 Further, instead of forming a button hole in the cover body and the connecting material and inserting the push button, the pin may be pierced through the cover body and the connecting material having no hole, whereby the push button is used as described above. The same effect as the effect of adopting the configuration can be obtained.

すなわち、参考の発明として、建築物のエキスパンションジョイント部のクリアランスを覆いつつ、該クリアランスの大きさの変化に追随して伸縮するエキスパンションジョイントカバーであって、伸縮可能な複数枚のカバー本体を伸縮方向と交差する方向に連結してなり、前記カバー本体の継目を跨ぐように連結材を重ねられると共に、カバー本体及び連結材にピンを突き通され、前記連結材を介して両側のカバー本体が連結されたことを特徴とするエキスパンションジョイントカバーを提供する。 That is, as a reference invention , it is an expansion joint cover that expands and contracts according to a change in the size of the clearance while covering the clearance of the expansion joint portion of the building. The connecting materials are stacked so as to straddle the seams of the cover main body, and the pins are pierced through the cover main body and the connecting material, and the cover main bodies on both sides are connected via the connecting material. It provides an expansion joint cover characterized by being done.

また、カバー本体及び連結材を蛇腹状に形成するようにしてもよい。 Further, the cover body and the connecting material may be formed in a bellows shape.

この構成によると、カバー本体及び連結材が伸縮する際、その蛇腹形状の山部及び谷部に歪が集中しやすいが、プッシュボタンを用いた連結構造を採用しているので、カバー本体と連結材とのずれを許容して、山部及び谷部における歪を吸収することができる。つまり、蛇腹状のカバー本体及び連結材を接着すると、山部及び谷部が一体的に歪んで、その接着が剥がれるなどの損傷を生じやすいが、適宜、山部及び谷部から外れた部位をプッシュボタンで連結することにより、山部及び谷部における歪を緩和することができる。 According to this configuration, when the cover body and the connecting material expand and contract, strain tends to concentrate on the bellows-shaped peaks and valleys, but since the connection structure using push buttons is adopted, it is connected to the cover body. It is possible to allow the deviation from the material and absorb the strain in the peaks and valleys. In other words, when the bellows-shaped cover body and the connecting material are adhered, the peaks and valleys are distorted integrally, and damage such as peeling of the adhesion is likely to occur. By connecting with a push button, distortion in peaks and valleys can be alleviated.

また、伸縮方向における両端部をフレームに取り付け、このフレームを、クリアランスを挟んで互いに対向する両側部位で支持するようにしてもよい。 Further, both ends in the expansion / contraction direction may be attached to the frame, and the frame may be supported by both side portions facing each other with a clearance in between.

この構成によると、例えば、エキスパンションジョイントカバーを、その両端部をフレームに仮止めして、クリアランスの大きさに合うよう伸縮させることができ、その際、プッシュボタンを用いてカバー本体の連結部分の剛性を小さくしているので、伸縮に伴う強い力が仮止め部分に作用して、エキスパンションジョイントカバーがフレームから外れるのを防止することができる。 According to this configuration, for example, an expansion joint cover can be temporarily fixed to the frame at both ends and expanded / contracted to fit the size of the clearance, and at that time, a push button is used to connect the connecting portion of the cover body. Since the rigidity is reduced, a strong force due to expansion and contraction acts on the temporarily fixed portion to prevent the expansion joint cover from coming off the frame.

以上のとおり、本発明によると、伸縮可能なカバー本体の継目を跨ぐように連結材を重ねて、カバー本体及び連結材に形成したボタン孔にプッシュボタンを挿入することにより、連結材を介して両側のカバー本体を連結するようにしている。これにより、複数枚のカバー本体を伸縮方向と交差する方向に容易に連結することができると共に、伸縮による損傷を防止することができる。 As described above, according to the present invention, the connecting materials are stacked so as to straddle the joint of the stretchable cover body, and the push button is inserted into the cover body and the button holes formed in the connecting material, thereby passing through the connecting material. The cover bodies on both sides are connected. As a result, a plurality of cover bodies can be easily connected in a direction intersecting the expansion / contraction direction, and damage due to expansion / contraction can be prevented.

以下、本発明に係るエキスパンションジョイントカバーを実施するための形態について、図面を用いて説明する。 Hereinafter, a mode for carrying out the expansion joint cover according to the present invention will be described with reference to the drawings.

図１～図４に示すように、エキスパンションジョイントカバー１は、建築物のエキスパンションジョイント部２のクリアランス３を覆いつつ、クリアランス３の大きさの変化に追随して伸縮するものであり、複数枚のカバー本体４の継目を跨ぐように、背面側に連結材５を重ねると共に、カバー本体４及び連結材５に形成されたボタン孔にプッシュボタン６を挿入することにより、連結材５を介して継目の両側のカバー本体４を連結して、複数枚のカバー本体４を伸縮方向と交差する上下方向に連結したものである。 As shown in FIGS. 1 to 4, the expansion joint cover 1 covers the clearance 3 of the expansion joint portion 2 of the building and expands and contracts according to the change in the size of the clearance 3, and has a plurality of sheets. By stacking the connecting material 5 on the back side so as to straddle the seam of the cover body 4, and inserting the push button 6 into the button holes formed in the cover body 4 and the connecting material 5, the seam is passed through the connecting material 5. The cover bodies 4 on both sides of the above are connected, and a plurality of cover bodies 4 are connected in the vertical direction intersecting the expansion / contraction direction.

このエキスパンションジョイントカバー１は、伸縮方向における両端部７をフレーム８に取り付けられ、フレーム８がクリアランス３を挟んで互いに対向する両側部位９、１０に支持される。 In the expansion joint cover 1, both ends 7 in the expansion / contraction direction are attached to the frame 8, and the frame 8 is supported by both side portions 9 and 10 facing each other with the clearance 3 interposed therebetween.

カバー本体４は、伸縮可能なよう正面側に突出する山部１１と背面側に突出する谷部１２とを有する蛇腹状の合成樹脂板とされ、両端の山部１１から両端部７が左右に広がり、この両端部７に、背面側に突出してフレーム８に仮止めされる突起部１３が形成されている。 The cover main body 4 is a bellows-shaped synthetic resin plate having a mountain portion 11 projecting to the front side and a valley portion 12 projecting to the back side so as to be expandable and contractible. Protruding portions 13 that are widened and project to the back surface side and are temporarily fixed to the frame 8 are formed on both end portions 7.

連結材５は、カバー本体４と同一素材で、カバー本体４の背面側に重なるよう山部１４及び谷部１５を有する蛇腹状の合成樹脂板とされ、カバー本体４よりも上下方向で幅狭に形成されている。 The connecting material 5 is made of the same material as the cover body 4, and is a bellows-shaped synthetic resin plate having ridges 14 and valleys 15 so as to overlap the back side of the cover body 4, and is narrower in the vertical direction than the cover body 4. Is formed in.

図１～図４に示すように、カバー本体４及び連結材５には、左右端及び中央の谷部１２を挟んで対をなし、かつ継目を挟んで対をなすよう、１か所に４つのボタン孔が３か所に形成され、各ボタン孔にプッシュボタン６を挿入されて、連結材５を介して継目の両側のカバー本体４が連結される。 As shown in FIGS. 1 to 4, the cover main body 4 and the connecting member 5 are paired with the left and right ends and the central valley portion 12 sandwiched between them, and the cover body 4 and the connecting member 5 are paired with each other across a seam. One button hole is formed at three places, a push button 6 is inserted into each button hole, and the cover main bodies 4 on both sides of the seam are connected via the connecting member 5.

図５に示すように、プッシュボタン６は、頭部１６から突出する軸部１７の先端に抜け止め１８を挿入する抜け止め孔１９を形成した構造とされ、カバー本体４の正面側から各ボタン孔に軸部１７を挿入されて、連結材５の背面側において、抜け止め孔１９に抜け止め１８を挿入されて固定される。 As shown in FIG. 5, the push button 6 has a structure in which a retaining hole 19 for inserting a retaining hole 18 is formed at the tip of a shaft portion 17 protruding from the head portion 16, and each button is formed from the front side of the cover body 4. The shaft portion 17 is inserted into the hole, and the retaining hole 18 is inserted into the retaining hole 19 and fixed on the back surface side of the connecting member 5.

図１に示すように、フレーム８は、カバー本体４の突起部１３を挿入して仮止めする挿入溝２０を有する例えばアルミニウム製のフレーム本体２１と、フレーム本体２１との間にカバー本体４の両端部７を挟持する例えばアルミニウム製の押え材２２とからなり、両側部位９、１０に固定されて、エキスパンションジョイントカバー１を支持する。 As shown in FIG. 1, the frame 8 has an insertion groove 20 for inserting and temporarily fixing a protrusion 13 of the cover main body 4, for example, an aluminum frame main body 21 and a cover main body 4 between the frame main body 21. It is composed of, for example, an aluminum presser foot 22 that sandwiches both end portions 7, and is fixed to both side portions 9 and 10 to support the expansion joint cover 1.

上記構成によれば、カバー本体４及び連結材５のボタン孔にプッシュボタン６を装着するだけでカバー本体４を連結することができ、しかも、プッシュボタン６で離散的に接続するので、伸縮の際に、カバー本体と連結材とのずれを許容でき、連結部分の剛性を小さくし、連結部分への力の集中を防止することができる。 According to the above configuration, the cover main body 4 can be connected only by attaching the push button 6 to the button holes of the cover main body 4 and the connecting member 5, and since the cover main body 4 is discretely connected by the push button 6, it can be expanded and contracted. At that time, the displacement between the cover body and the connecting material can be tolerated, the rigidity of the connecting portion can be reduced, and the concentration of force on the connecting portion can be prevented.

また、連結部分の剛性が小さい分、カバー本体４の突起部１３を挿入溝２０に挿入してフレーム本体２１に仮止めし、クリアランス３の大きさに合うよう伸縮させた後、押え材２２で固定するまでの間、伸縮に伴う強い力が作用することがなく、仮止めが外れるのを防止することができる。 Further, since the rigidity of the connecting portion is small, the protrusion 13 of the cover main body 4 is inserted into the insertion groove 20, temporarily fixed to the frame main body 21, expanded and contracted to match the size of the clearance 3, and then the holding material 22 is used. Until it is fixed, the strong force associated with expansion and contraction does not act, and it is possible to prevent the temporary fixing from coming off.

なお、本発明は、上記の実施の形態に限定されるものではなく、本発明の範囲内において、適宜変更を加えることができる。また、参考の形態として、例えば、図６に示すように、カバー本体４及び連結材５にボタン孔を形成してプッシュボタン６を挿入する代わりに、孔のないカバー本体４及び連結材５にピン２３を突き通すようにしてもよい。 The present invention is not limited to the above embodiment, and modifications can be made as appropriate within the scope of the present invention. Further, as a reference form, for example, as shown in FIG. 6, instead of forming a button hole in the cover main body 4 and the connecting material 5 and inserting the push button 6, the cover main body 4 and the connecting material 5 having no hole are inserted. The pin 23 may be pierced.

具体的には、まず、孔のないカバー本体４及び連結材５の所定の位置に、先の尖ったピン２３を突き通し、カバー本体４及び連結材５の反対側に配置した例えばスプリングワッシャー２４にピン先２５を通して、このピン先２５を折り曲げて固定すればよい。 Specifically, first, for example, a spring washer 24 in which a pointed pin 23 is pierced at a predetermined position of a cover main body 4 and a connecting member 5 having no holes and arranged on the opposite side of the cover main body 4 and the connecting member 5. The pin tip 25 may be passed through the pin tip 25, and the pin tip 25 may be bent and fixed.

また、エキスパンションジョイントカバー１の両端部７をフレーム８に取り付けることなく、クリアランス３を挟んで互いに対向する両側部位９、１０で支持するようにしてもよい。また、カバー本体４及び連結材５は、伸縮可能なものであればよく、必ずしも蛇腹状に形成する必要はない。 Further, both ends 7 of the expansion joint cover 1 may not be attached to the frame 8 but may be supported by the side portions 9 and 10 facing each other with the clearance 3 interposed therebetween. Further, the cover body 4 and the connecting member 5 may be stretchable as long as they can be expanded and contracted, and do not necessarily have to be formed in a bellows shape.
