Description

本発明は、長さ方向に沿って隣り合う笠木同士を接続する笠木ジョイントカバーを用いて、長さ方向に沿って隣り合う笠木同士を接続する笠木の接続構造に関する。 The present invention uses coping joint cover for connecting coping adjacent along the longitudinal direction, on the connection structure for coping connecting the coping adjacent along the longitudinal direction.

従来、バルコニー等に形成される手摺壁の上端面には、長さ方向に沿って隣り合う複数の笠木が設けられており、これら複数の笠木間には、これら複数の笠木間の目地部の防水性を向上させるため、この目地部を覆う継目カバーが取り付けられている（例えば、特許文献１参照）。また、隣り合う笠木間の目地部は、これら隣り合う笠木間に適宜間隔を空けることによって形成されている。
特開平１１−０９３３５７号公報 Conventionally, the upper end surface of the handrail wall formed on the balcony or the like has been provided with a plurality of adjacent headboards along the length direction, and the joint portion between the plurality of headboards is provided between the plurality of headboards. In order to improve waterproofness, a seam cover that covers the joint portion is attached (for example, see Patent Document 1). Moreover, the joint part between adjacent caps is formed by providing an appropriate space between the adjacent caps.
Japanese Patent Laid-Open No. 11-093357

ところで、例えば風圧や、人や物による接触等の外力により、目地部を設けた分だけ笠木が位置ずれしてしまう場合がある。この時、位置ずれした笠木の一方の端部と、隣り合う一方の笠木の端部とがぶつかり合うことによって、これら笠木間の目地部が閉塞されてしまうとともに、位置ずれした笠木の他方の端部と、隣り合う他方の笠木の端部との間に大きな隙間が形成されてしまう場合がある。そして、このような大きな隙間が、上述のような継目カバーで覆うことができる範囲よりも大きなものであった場合、継目カバーによって雨水等を防ぐことができないので、好ましくない。 By the way, there is a case where the headboard is displaced by an amount corresponding to the joint portion due to, for example, an external force such as wind pressure or contact with a person or an object. At this time, one end of the offset headboard collides with the end of one of the adjacent headboards, thereby closing the joint between the headboards and the other end of the offset headboard. There may be a case where a large gap is formed between the portion and the end of the other adjacent headboard. And when such a big clearance gap is larger than the range which can be covered with the above-mentioned seam cover, since rainwater etc. cannot be prevented with a seam cover, it is not preferable.

一方、隣り合う笠木同士が施工誤差によって、隣り合う笠木のそれぞれの上面の高さ位置が異なり、目地部を境に段差が生じてしまう場合があるが、特許文献１のような継目カバーでは、この施工誤差を吸収しきれないという場合がある。すなわち、特許文献１の継目カバーは、この継目カバーの両端部の係止爪を、笠木の側面に形成された段部に係合することで、笠木に取り付けられている。また、この継目カバーの裏面には、継目カバーと笠木とを離隔させる弾性体が設けられている。したがって、特許文献１の継目カバーでは、上述のような施工誤差が生じてしまうと、係止爪を段部に係合できない場合があり、無理に係合させたとしてもすぐに外れてしまう場合があった。 On the other hand, the height positions of the upper surfaces of the adjacent caps are different due to construction errors between the adjacent caps, and a step may occur at the joint, but in the joint cover as in Patent Document 1, In some cases, this construction error cannot be absorbed. That is, the joint cover of Patent Document 1 is attached to the headboard by engaging the engaging claws at both ends of the seam cover with the step portions formed on the side face of the headboard. In addition, an elastic body that separates the joint cover and the headboard is provided on the back surface of the joint cover. Therefore, in the joint cover of Patent Document 1, if the above-described construction error occurs, the locking claw may not be able to engage with the stepped portion, and even if it is forcedly engaged, it will come off immediately. was there.

本発明の課題は、笠木の位置ずれを確実に防ぐことができるとともに、隣り合う笠木間の施工誤差を確実に吸収できる笠木の接続構造を提供することを目的とする。 An object of the present invention, it is possible to reliably prevent positional deviation of the coping, and an object thereof is to provide a connecting structure of Ru can reliably absorb the construction errors between adjacent coping bevel tree.

請求項１に記載の発明によれば、前記第１突条部２０の先端に、前記笠木２，２間の目地部２ａの延在方向に直交する方向に突出して、前記隣り合う笠木２，２の双方の端部の裏面に当接する突出部２１が設けられていることから、前記カバー本体１０によって前記隣り合う笠木２，２間の目地部２ａを覆いながら、このカバー本体１０の裏面と前記第１突条部２０の突出部２１とによって、前記隣り合う笠木２，２の双方の端部を挟み込むことができるので、前記笠木ジョイントカバー１によって前記隣り合う笠木２，２同士を接続することができる。その上、このように前記第１突条部２０の突出部２１が、前記隣り合う笠木２，２の双方の端部の裏面に当接するので、この突出部２１が前記笠木２，２の端部の裏面に引っ掛かった状態となり、前記笠木ジョイントカバー１を、前記隣り合う笠木２，２間の目地部２ａから外れにくくすることができる。
また、前記第１および第２突条部２０，３０が、前記隣り合う笠木２，２間の目地部２ａに差し込まれるので、これら第１および第２突条部２０，３０によって、前記隣り合う笠木２，２間の目地部２ａを埋めることができるとともに、前記隣り合う笠木２，２同士の間隔を適当な寸法に保持できる。これによって、外力等によって笠木２が位置ずれを起こしてしまうことを確実に防ぐことができるので、隣り合う笠木２，２間に大きな隙間が形成されることを確実に防ぐことができる。
さらに、前記第１および第２突条部２０，３０は、互いに間隔をあけて断続的に配置されているので、前記笠木２，２間の目地部２ａの延在方向に沿って設けられる第１および第２突条部２０，３０間には、隙間が形成されていることとなる。これによって、前記第１および第２突条部２０，３０を、前記カバー本体１０の裏面に、前記笠木２，２間の目地部２ａの延在方向にわたって設ける必要がないので、製造に係るコストを低減できる。さらに、形状の異なる第１および第２突条部２０，３０同士を切り離して形成できるので、形状の異なる第１および第２突条部２０，３０同士を連続させて形成する場合に比して、格段に製造しやすい。
また、前記カバー本体１０と、前記第１および第２突条部２０，３０は、一体的に形成されるとともに、弾力性を有しているので、例えば隣り合う笠木２，２間に段差が生じてしまうような施工誤差が生じた場合であっても、この施工誤差に合わせて前記カバー本体２０と、前記第１および第２突条部２０，３０を変形させることができ、施工誤差を確実に吸収することができる。
しかも、このように前記カバー本体１０と、前記第１および第２突条部２０，３０は、一体的に形成されるとともに、弾力性を有しており、前記第１および第２突条部２０，３０は、互いに間隔をあけて断続的に配置されていることから、前記カバー本体１０を広げるようにして変形させることができるので、前記笠木ジョイントカバー１を、前記隣り合う笠木２，２同士の接続部分に取り付ける際に取り付けやすい。
また、前記カバー本体１０は、前記隣り合う笠木２，２の上面を覆う上面部１１と、この上面部１１の両端部に設けられるとともに、前記隣り合う笠木２，２の側面を覆う側面部１２とを備えているので、このカバー本体１０によって、前記隣り合う笠木２，２間の目地部２ａを確実に覆い隠すことができる。
また、前記上面部１１の裏面に設けられる第１突条部２０および第２突条部３０は、交互に配置されているので、前記上面部１１に対し、前記第１突条部２０が固まって配置されていたり、前記第２突条部３０が固まって配置されていたり等の偏りがない状態で配置できる。したがって、前記上面部１１に設けられた第１突条部２０を、前記隣り合う笠木２，２の上面端部間の目地部２ａに差し込むことによって、前記カバー本体１０の上面部１１を、前記隣り合う笠木２，２同士の上面に確実に取り付けできる。しかも、前記上面部１１に設けられた第１および第２突条部２０，３０を、前記隣り合う笠木２，２の上面端部間の目地部２ａに差し込むことによって、この隣り合う笠木２，２の上面端部間の目地部２ａを埋めることができるとともに、前記隣り合う笠木２，２同士の間隔を適当な寸法に保持できる。
さらに、前記側面部１２の裏面には、前記第１突条部２０が設けられているので、これら第１突条部２０を、前記隣り合う笠木２，２の側面端部間の目地部２ａに差し込むことによって、前記カバー本体１０の側面部１２を、前記隣り合う笠木２，２同士の側面に確実に取り付けできる。しかも、この第１突条部２０を、前記隣り合う笠木２，２の側面端部間の目地部２ａに差し込むことによって、この隣り合う笠木２，２の側面端部間の目地部２ａを埋めることができるとともに、前記隣り合う笠木２，２同士の間隔を適当な寸法に保持できる。
また、前記カバー本体１０の裏面と、前記隣り合う笠木２，２の上面との間には、防水性および接着性を有するシール材６が充填されているので、このシール材６によって、前記カバー本体１０の裏面と、前記隣り合う笠木２，２の上面とを接着できるとともに、前記隣り合う笠木２，２間における防水性を高めることができる。さらに、このように前記カバー本体１０の裏面と、前記隣り合う笠木２，２の上面とが接着されるので、前記隣り合う笠木２，２の一方が動いた場合であっても、前記カバー本体１０が、この笠木２の動きに合わせて変形し、笠木ジョイントカバー１自体がさらに外れにくくなる。 According to invention of Claim 1, it protrudes in the direction orthogonal to the extension direction of the joint part 2a between the said caps 2 and 2 at the front-end | tip of the said 1st protrusion part 20, and the said adjacent caps 2, 2 is provided with the protrusions 21 in contact with the back surfaces of both ends of the cover 2, the cover body 10 covers the joint 2 a between the adjacent caps 2 and 2, Since both ends of the adjacent caps 2 and 2 can be sandwiched by the projecting portion 21 of the first protrusion 20, the adjacent caps 2 and 2 are connected by the cap joint cover 1. be able to. In addition, since the projecting portion 21 of the first protrusion 20 abuts against the back surface of both end portions of the adjacent caps 2 and 2, the projecting portion 21 becomes the end of the caps 2 and 2. It becomes the state caught in the back surface of a part, and can make it difficult to remove the said headboard joint cover 1 from the joint part 2a between the said adjacent headboards 2 and 2. FIG.
Further, since the first and second protrusions 20 and 30 are inserted into the joint portion 2a between the adjacent headboards 2 and 2, the first and second protrusions 20 and 30 are adjacent to each other. The joint portion 2a between the caps 2 and 2 can be filled, and the distance between the adjacent caps 2 and 2 can be maintained at an appropriate size. Accordingly, it is possible to reliably prevent the position of the headboard 2 from being displaced due to an external force or the like, and thus it is possible to reliably prevent a large gap from being formed between the adjacent headboards 2 and 2.
Further, since the first and second protrusions 20 and 30 are intermittently arranged at intervals, the first and second protrusions 20 and 30 are provided along the extending direction of the joint 2a between the caps 2 and 2. A gap is formed between the first and second protrusions 20 and 30. This eliminates the need to provide the first and second protrusions 20 and 30 on the back surface of the cover body 10 over the extending direction of the joint 2a between the caps 2 and 2, so that the manufacturing cost is reduced. Can be reduced. Furthermore, since the first and second protrusions 20 and 30 having different shapes can be formed separately from each other, compared to the case where the first and second protrusions 20 and 30 having different shapes are continuously formed. Easy to manufacture.
Further, since the cover body 10 and the first and second protrusions 20 and 30 are integrally formed and have elasticity, for example, there is a step between the adjacent headboards 2 and 2. Even when a construction error occurs, the cover main body 20 and the first and second protrusions 20 and 30 can be deformed in accordance with the construction error. Can be absorbed reliably.
In addition, the cover main body 10 and the first and second ridges 20 and 30 are formed integrally and have elasticity, and thus the first and second ridges. Since 20 and 30 are intermittently arranged at intervals from each other, the cover main body 10 can be deformed so that the cover main body 10 is widened. It is easy to attach when attaching to the connecting part between each other.
The cover body 10 is provided with an upper surface portion 11 covering the upper surfaces of the adjacent headboards 2 and 2, and a side surface portion 12 provided at both ends of the upper surface portion 11 and covering the side surfaces of the adjacent headboards 2 and 2. The cover main body 10 can reliably cover the joint portion 2a between the adjacent caps 2 and 2.
In addition, since the first protrusions 20 and the second protrusions 30 provided on the back surface of the upper surface part 11 are alternately arranged, the first protrusions 20 are solidified with respect to the upper surface part 11. Can be arranged in a state where there is no bias, such as being arranged, or the second protrusion 30 being solidly arranged. Therefore, by inserting the first protrusion 20 provided on the upper surface portion 11 into the joint portion 2a between the upper surface end portions of the adjacent headboards 2, 2, the upper surface portion 11 of the cover body 10 is It can be securely attached to the upper surfaces of adjacent caps 2 and 2. Moreover, by inserting the first and second protrusions 20 and 30 provided on the upper surface portion 11 into the joint portion 2a between the upper surface end portions of the adjacent caps 2 and 2, The joint portion 2a between the upper end portions of the two upper surfaces can be filled, and the distance between the adjacent headboards 2 and 2 can be maintained at an appropriate size.
Furthermore, since the first ridges 20 are provided on the back surface of the side surface 12, the first ridges 20 are connected to the joints 2 a between the side edges of the adjacent caps 2, 2. By inserting it into the side, the side surface 12 of the cover body 10 can be securely attached to the side surfaces of the adjacent headboards 2 and 2. In addition, the joint portion 2a between the side end portions of the adjacent headboards 2, 2 is filled by inserting the first protrusion 20 into the joint portion 2a between the side end portions of the adjacent headboards 2, 2. In addition, the distance between the adjacent caps 2 and 2 can be maintained at an appropriate size.
Further, since the sealing material 6 having waterproofness and adhesiveness is filled between the back surface of the cover main body 10 and the upper surfaces of the adjacent caps 2 and 2, the sealing material 6 allows the cover to cover the cover body 10. The back surface of the main body 10 and the upper surfaces of the adjacent caps 2 and 2 can be bonded, and the waterproofness between the adjacent caps 2 and 2 can be enhanced. Further, since the back surface of the cover main body 10 and the upper surfaces of the adjacent headboards 2 and 2 are bonded in this way, even if one of the adjacent headboards 2 and 2 moves, the cover main body 10 10 is deformed in accordance with the movement of the headboard 2, and the headboard joint cover 1 itself is more difficult to be removed.

請求項２に記載の発明は、例えば図１および図７に示すように、請求項１に記載の笠木の接続構造において、
前記側面部１２の下端部には、これら側面部１２の下端部から折り返すようにして内方に突出することによって、前記隣り合う笠木２，２の両側面の下端部に係止する折り返し部１３がそれぞれ設けられていることを特徴とする。 The invention described in claim 2 is, as shown in FIGS. 1 and 7, for example , in the connection structure of the headboard according to claim 1 ,
At the lower end portion of the side surface portion 12, the folded portion 13 that engages with the lower end portions of both side surfaces of the adjacent headboards 2, 2 by projecting inward so as to be folded back from the lower end portions of the side surface portions 12. Are provided, respectively.

請求項２に記載の発明によれば、前記側面部１２の下端部には、これら側面部１２の下端部から折り返すようにして内方に突出することによって、前記隣り合う笠木２，２の両側面の下端部に係止する折り返し部１３がそれぞれ設けられているので、前記カバー本体１０を、前記隣り合う笠木２，２の端部に、これら隣り合う笠木２，２の両側面を巻き込むようにして取り付けできる。これによって、前記カバー本体１０の側面部１２の下端部が、前記隣り合う笠木２，２の両側面の下端部に引っ掛かることとなるので、前記カバー本体１０の取付状態を向上させることができる。 According to the invention described in claim 2 , the lower end portions of the side surface portions 12 protrude inward so as to be folded back from the lower end portions of the side surface portions 12, thereby providing both sides of the adjacent headboards 2, 2. Since the folding | returning part 13 latched to the lower end part of a surface is each provided, the said cover main body 10 is wound around the edge part of the said adjacent headboards 2 and 2 so that both the side surfaces of these adjacent headboards 2 and 2 may be wound. Can be attached. As a result, the lower end portion of the side surface portion 12 of the cover main body 10 is caught by the lower end portions of both side surfaces of the adjacent headboards 2 and 2, so that the mounting state of the cover main body 10 can be improved.

請求項３に記載の発明は、例えば図１および図７に示すように、請求項１または２に記載の笠木の接続構造において、
前記折り返し部１３は、前記隣り合う笠木２，２のうち、一方の笠木２の側面の下端部に係止する第１折り返し片１３ａと、他方の笠木２の側面の下端部に係止する第２折り返し片１３ｂとからなり、
これら第１係止片１３ａと第２係止片１３ｂは、互いに間隔をあけて配置されていることを特徴とする。 The invention described in claim 3 is, for example, as shown in FIG. 1 and FIG. 7, in the connection structure of the headboard of claim 1 or 2 ,
The folded portion 13 includes a first folded piece 13 a that is locked to the lower end portion of the side surface of one of the adjacent caps 2, 2, and a 2 folded pieces 13b,
The first locking piece 13a and the second locking piece 13b are characterized by being spaced apart from each other.

請求項３に記載の発明によれば、前記第１係止片１３ａと第２係止片１３ｂは、互いに間隔をあけて配置されているので、これら第１係止片１３ａと第２係止片１３ｂとの間に隙間を形成することができる。これによって、前記隣り合う笠木２，２間の目地部２ａから雨水等が浸入した際に、前記カバー本体１０の裏面を伝って流れる雨水等を、前記第１および第２係止片１３ａ，１３ｂ間の隙間から容易に排出することができる。 According to the third aspect of the present invention, since the first locking piece 13a and the second locking piece 13b are spaced apart from each other, the first locking piece 13a and the second locking piece A gap can be formed between the piece 13b. Accordingly, when rainwater or the like enters from the joint portion 2a between the adjacent caps 2 and 2, rainwater or the like flowing along the back surface of the cover body 10 is caused to flow into the first and second locking pieces 13a and 13b. It can be easily discharged from the gap between them.

本発明によれば、カバー本体の裏面に設けられる第１突条部の先端に、隣り合う笠木間の目地部の延在方向に直交する方向に突出して、隣り合う笠木の双方の端部の裏面に当接する突出部が設けられていることから、カバー本体によって隣り合う笠木間の目地部を覆いながら、このカバー本体の裏面と第１突条部の突出部とによって、隣り合う笠木の双方の端部を挟み込むことができるので、笠木ジョイントカバーによって隣り合う笠木同士を接続することができる。その上、このように第１突条部の突出部が、隣り合う笠木の双方の端部の裏面に当接するので、この突出部が笠木の端部の裏面に引っ掛かった状態となり、笠木ジョイントカバーを、隣り合う笠木間の目地部から外れにくくすることができる。
また、カバー本体の裏面に設けられる第１および第２突条部が、隣り合う笠木間の目地部に差し込まれるので、これら第１および第２突条部によって、隣り合う笠木間の隙間を埋めることができるとともに、隣り合う笠木同士の間隔を適当な寸法に保持できる。これによって、外力等によって笠木が位置ずれを起こしてしまうことを確実に防ぐことができるので、隣り合う笠木間に大きな隙間が形成されることを確実に防ぐことができる。
さらに、第１および第２突条部は、互いに間隔をあけて断続的に配置されているので、笠木間の目地部の延在方向に沿って設けられる第１および第２突条部間には、隙間が形成されていることとなる。これによって、第１および第２突条部を、カバー本体の裏面に、笠木間の目地部の延在方向にわたって設ける必要がないので、製造に係るコストを低減できる。さらに、形状の異なる第１および第２突条部同士を切り離して形成できるので、形状の異なる第１および第２突条部同士を連続させて形成する場合に比して、格段に製造しやすい。
また、カバー本体と、第１および第２突条部は、一体的に形成されるとともに、弾力性を有しているので、例えば隣り合う笠木間に段差が生じてしまうような施工誤差が生じた場合であっても、この施工誤差に合わせてカバー本体と、第１および第２突条部を変形させることができ、施工誤差を確実に吸収することができる。
しかも、このようにカバー本体と、第１および第２突条部は、一体的に形成されるとともに、弾力性を有しており、これら第１および第２突条部は、互いに間隔をあけて断続的に配置されていることから、カバー本体を広げるようにして変形させることができるので、笠木ジョイントカバーを、隣り合う笠木同士の接続部分に取り付ける際に取り付けやすい。 According to the present invention, the first projecting portion provided on the back surface of the cover main body protrudes in the direction perpendicular to the extending direction of the joint portion between the adjacent headboards, and the both ends of the adjacent headboards. Since the projecting portion that comes into contact with the back surface is provided, both the adjacent headboards are covered by the back surface of the cover body and the projecting portion of the first protrusion while covering the joint portion between the adjacent headboards by the cover body. As a result, the adjacent caps can be connected to each other by the caps joint cover. In addition, since the protrusions of the first protrusions abut against the back surfaces of both ends of the adjacent headboards, the protrusions are caught on the back surfaces of the end parts of the headboards. Can be made difficult to disengage from the joint between adjacent caps.
Moreover, since the 1st and 2nd protrusion part provided in the back surface of a cover main body is inserted in the joint part between adjacent headboards, the clearance gap between adjacent headboards is filled with these 1st and 2nd protrusion parts. In addition, it is possible to keep the spacing between adjacent headboards at an appropriate size. Accordingly, it is possible to reliably prevent the position of the headboard from being displaced due to an external force or the like, and thus it is possible to reliably prevent a large gap from being formed between the adjacent headboards.
Furthermore, since the first and second protrusions are intermittently arranged with a space between each other, the first and second protrusions are provided between the first and second protrusions provided along the extending direction of the joint between the headboards. A gap is formed. Accordingly, it is not necessary to provide the first and second protrusions on the back surface of the cover main body over the extending direction of the joint between the headboards, so that the manufacturing cost can be reduced. Furthermore, since the first and second protrusions having different shapes can be formed separately, the first and second protrusions having different shapes can be formed easily compared to the case where the first and second protrusions having different shapes are continuously formed. .
Moreover, since the cover body and the first and second protrusions are formed integrally and have elasticity, for example, a construction error that causes a step between adjacent headboards occurs. Even if it is a case, a cover main body and a 1st and 2nd protrusion part can be changed according to this construction error, and a construction error can be absorbed reliably.
In addition, the cover body and the first and second protrusions are formed integrally and have elasticity, and the first and second protrusions are spaced from each other. Since the cover body can be expanded and deformed by being intermittently disposed, it is easy to attach the headboard joint cover when the headboard joint cover is attached to the connecting portion between the adjacent headboards.

さらに、前記側面部１２の裏面に、前記第１突条部２０が設けられているので、これら第１突条部２０を、前記隣り合う笠木２，２の側面端部間の目地部２ａに差し込むことによって、前記カバー本体１０の側面部１２を、前記隣り合う笠木２，２同士の側面に確実に取り付けできる。
しかも、この第１突条部２０を、前記隣り合う笠木２，２の側面端部間の目地部２ａに差し込むことによって、この隣り合う笠木２，２の側面端部間の目地部２ａを埋めることができるとともに、前記隣り合う笠木２，２同士の間隔を適当な寸法に保持できるようになっている。 Furthermore, since the first protrusions 20 are provided on the back surface of the side part 12, the first protrusions 20 are connected to the joint part 2a between the side end parts of the adjacent caps 2 and 2. By inserting, the side surface portion 12 of the cover body 10 can be securely attached to the side surfaces of the adjacent headboards 2 and 2.
In addition, the joint portion 2a between the side end portions of the adjacent headboards 2, 2 is filled by inserting the first protrusion 20 into the joint portion 2a between the side end portions of the adjacent headboards 2, 2. In addition, the distance between the adjacent caps 2 and 2 can be maintained at an appropriate size.

また、以上のようなカバー本体１０と、第１および第２突条部２０，３０は、上述のように、一体的に形成されるとともに、弾力性を有している。なお、材質としては、例えばソフトアクリル等の軟質で弾力性の高い樹脂材料が用いられている。ただし、これに限るものではない。
そして、このように前記カバー本体１０と、前記第１および第２突条部２０，３０は、一体的に形成されるとともに、弾力性を有しているので、例えば隣り合う笠木２，２間に段差が生じてしまうような施工誤差が生じた場合であっても、図６に示すように、この施工誤差に合わせて前記カバー本体２０と、前記第１および第２突条部２０，３０を変形させることができる。 Further, the cover main body 10 and the first and second protrusions 20 and 30 as described above are integrally formed and have elasticity as described above. As a material, for example, a soft and highly elastic resin material such as soft acrylic is used. However, the present invention is not limited to this.
In this way, the cover body 10 and the first and second protrusions 20 and 30 are integrally formed and have elasticity, so that, for example, between the adjacent headboards 2 and 2 Even if there is a construction error that causes a difference in level, as shown in FIG. 6, the cover body 20 and the first and second protrusions 20 and 30 are matched to the construction error. Can be deformed.

一方、前記カバー本体１０の双方の側面部１２の下端部には、図１および図７に示すように、これら側面部１２の下端部から折り返すようにして内方に突出することによって、前記隣り合う笠木２，２の両側面の下端部に係止する折り返し部１３がそれぞれ設けられている。
また、この折り返し部１３は、図１に示すように、前記カバー本体の双方の側端部１２の下端部から水平方向に沿って前記カバー本体１０の内部側に突出する部分と、このカバー本体１０の内部側に突出する部分の突出方向先端から上方に突出する部分とで構成されている。 On the other hand, as shown in FIG. 1 and FIG. 7, the lower ends of both side surface portions 12 of the cover body 10 protrude inward so as to be folded back from the lower end portions of the side surface portions 12, thereby The folding | returning part 13 latched to the lower end part of the both sides | surfaces of the matching headboards 2 and 2 is each provided.
Further, as shown in FIG. 1, the folded portion 13 includes a portion protruding from the lower ends of the side end portions 12 of the cover main body 12 toward the inner side of the cover main body 10 along the horizontal direction, and the cover main body. 10 and a portion that protrudes upward from the tip in the protruding direction of the portion that protrudes to the inner side.

そして、このような折り返し部１３は、前記カバー本体の双方の側端部１２の下端部と、この下端部から水平方向に沿って前記カバー本体１０の内部側に突出する部分と、このカバー本体１０の内部側に突出する部分の突出方向先端から上方に突出する部分とによって、前記隣り合う笠木２，２の両側面を巻き込むようにして、これら両側面の下端部に引っ掛けられることとなる。これによって、前記カバー本体１０の取付状態を向上させることができるようになっている。 And such a folding | returning part 13 is the lower end part of the side edge part 12 of the both sides of the said cover main body, the part which protrudes in the inner side of the said cover main body 10 along this horizontal direction from this lower end part, and this cover main body 10 is hooked to the lower end portions of both side surfaces of the adjacent headboards 2 and 2 by the portions protruding upward from the front end in the protruding direction of the portion protruding to the inner side. Thereby, the mounting state of the cover body 10 can be improved.

また、前記折り返し部１３は、図７に示すように、前記隣り合う笠木２，２のうち、一方の笠木２の側面の下端部に係止する第１折り返し片１３ａと、他方の笠木２の側面の下端部に係止する第２折り返し片１３ｂとからなり、これら第１係止片１３ａと第２係止片１３ｂは、互いに間隔をあけて配置されている。
すなわち、これら第１係止片１３ａと第２係止片１３ｂとの間に隙間を形成することができる。これによって、前記隣り合う笠木２，２間の目地部２ａから雨水等が浸入した際に、前記カバー本体１０の裏面を伝って流れる雨水等を、前記第１および第２係止片１３ａ，１３ｂ間の隙間から容易に排出することができる。 In addition, as shown in FIG. 7, the folded portion 13 includes a first folded piece 13 a that is locked to the lower end portion of the side surface of one of the adjacent caps 2 and 2, and the other caps 2. It consists of the 2nd folding | turning piece 13b latched to the lower end part of a side surface, These 1st locking piece 13a and 2nd locking piece 13b are arrange | positioned at intervals.
That is, a gap can be formed between the first locking piece 13a and the second locking piece 13b. Accordingly, when rainwater or the like enters from the joint portion 2a between the adjacent caps 2 and 2, rainwater or the like flowing along the back surface of the cover body 10 is caused to flow into the first and second locking pieces 13a and 13b. It can be easily discharged from the gap between them.

また、このように前記第１および第２係止片１３ａ，１３ｂ間の隙間から排出される雨水等は、前記水切り部材５によって、前記手摺壁３の上端面に到達することを防ぐことができるようになっている。 In addition, rainwater or the like discharged from the gap between the first and second locking pieces 13a and 13b can be prevented from reaching the upper end surface of the handrail wall 3 by the draining member 5. It is like that.

なお、前記第１突条部２０は、この折り返し部１３の箇所も避けて設けられている。すなわち、この折り返し部１３と、前記カバー本体１０の側面部１２の裏面に設けられる第１突条部２０との間には隙間が形成されていることとなる。
これによって、前記第１および第２突条部２０，３０を、前記カバー本体１０の裏面に、前記笠木２，２間の目地部２ａの延在方向にわたって設ける必要がなくなり、より製造に係るコストを低減できる。さらに、前記第１突条部２０および折り返し部１３同士を切り離して形成できるので、これら第１突条部２０および折り返し部１３同士を連続させて形成する場合に比して、格段に製造しやすい。 In addition, the said 1st protrusion part 20 is provided avoiding the location of this folding | returning part 13. FIG. That is, a gap is formed between the folded portion 13 and the first ridge portion 20 provided on the back surface of the side surface portion 12 of the cover body 10.
Thereby, it is not necessary to provide the first and second protrusions 20 and 30 on the back surface of the cover body 10 over the extending direction of the joint 2a between the caps 2 and 2, and more cost for manufacturing. Can be reduced. Furthermore, since the first protrusions 20 and the turn-up parts 13 can be formed separately from each other, it is much easier to manufacture compared to the case where the first protrusions 20 and the turn-up parts 13 are formed continuously. .

以上のような本実施の形態の笠木ジョイントカバー１によれば、前記第１突条部２０の先端に、前記笠木２，２間の目地部２ａの延在方向に直交する方向に突出して、前記隣り合う笠木２，２の双方の端部の裏面に当接する突出部２１が設けられていることから、前記カバー本体１０によって前記隣り合う笠木２，２間の目地部２ａを覆いながら、このカバー本体１０の裏面と前記第１突条部２０の突出部２１とによって、前記隣り合う笠木２，２の双方の端部を挟み込むことができるので、前記笠木ジョイントカバー１によって前記隣り合う笠木２，２同士を接続することができる。
その上、このように前記第１突条部２０の突出部２１が、前記隣り合う笠木２，２の双方の端部の裏面に当接するので、この突出部２１が前記笠木２，２の端部の裏面に引っ掛かった状態となり、前記笠木ジョイントカバー１を、前記隣り合う笠木２，２間の目地部２ａから外れにくくすることができる。
また、前記第１および第２突条部２０，３０が、前記隣り合う笠木２，２間の目地部２ａに差し込まれるので、これら第１および第２突条部２０，３０によって、前記隣り合う笠木２，２間の目地部２ａを埋めることができるとともに、前記隣り合う笠木２，２同士の間隔を適当な寸法に保持できる。これによって、外力等によって笠木２が位置ずれを起こしてしまうことを確実に防ぐことができるので、隣り合う笠木２，２間に大きな隙間が形成されることを確実に防ぐことができる。
さらに、前記第１および第２突条部２０，３０は、互いに間隔をあけて断続的に配置されているので、前記笠木２，２間の目地部２ａの延在方向に沿って設けられる第１および第２突条部２０，３０間には、隙間が形成されていることとなる。これによって、前記第１および第２突条部２０，３０を、前記カバー本体１０の裏面に、前記笠木２，２間の目地部２ａの延在方向にわたって設ける必要がないので、製造に係るコストを低減できる。さらに、形状の異なる第１および第２突条部２０，３０同士を切り離して形成できるので、形状の異なる第１および第２突条部２０，３０同士を連続させて形成する場合に比して、格段に製造しやすい。
また、前記カバー本体１０と、前記第１および第２突条部２０，３０は、一体的に形成されるとともに、弾力性を有しているので、例えば隣り合う笠木２，２間に段差が生じてしまうような施工誤差が生じた場合であっても、この施工誤差に合わせて前記カバー本体２０と、前記第１および第２突条部２０，３０を変形させることができ、施工誤差を確実に吸収することができる。
しかも、このように前記カバー本体１０と、前記第１および第２突条部２０，３０は、一体的に形成されるとともに、弾力性を有しており、前記第１および第２突条部２０，３０は、互いに間隔をあけて断続的に配置されていることから、前記カバー本体１０を広げるようにして変形させることができるので、前記笠木ジョイントカバー１を、前記隣り合う笠木２，２同士の接続部分に取り付ける際に取り付けやすい。 According to the headboard joint cover 1 of the present embodiment as described above, the front end of the first protrusion 20 protrudes in a direction perpendicular to the extending direction of the joint portion 2a between the headboards 2 and 2, Since the protrusions 21 that contact the back surfaces of both end portions of the adjacent caps 2 and 2 are provided, the cover body 10 covers the joint 2a between the adjacent caps 2 and 2 while covering the joint 2a. Since both ends of the adjacent caps 2 and 2 can be sandwiched between the back surface of the cover main body 10 and the protrusions 21 of the first protrusions 20, the adjacent caps 2 are covered by the caps joint cover 1. , 2 can be connected to each other.
In addition, since the projecting portion 21 of the first protrusion 20 abuts against the back surface of both end portions of the adjacent caps 2 and 2, the projecting portion 21 becomes the end of the caps 2 and 2. It becomes the state caught in the back surface of a part, and can make it difficult to remove the said headboard joint cover 1 from the joint part 2a between the said adjacent headboards 2 and 2. FIG.
Further, since the first and second protrusions 20 and 30 are inserted into the joint portion 2a between the adjacent headboards 2 and 2, the first and second protrusions 20 and 30 are adjacent to each other. The joint portion 2a between the caps 2 and 2 can be filled, and the distance between the adjacent caps 2 and 2 can be maintained at an appropriate size. Accordingly, it is possible to reliably prevent the position of the headboard 2 from being displaced due to an external force or the like, and thus it is possible to reliably prevent a large gap from being formed between the adjacent headboards 2 and 2.
Further, since the first and second protrusions 20 and 30 are intermittently arranged at intervals, the first and second protrusions 20 and 30 are provided along the extending direction of the joint 2a between the caps 2 and 2. A gap is formed between the first and second protrusions 20 and 30. This eliminates the need to provide the first and second protrusions 20 and 30 on the back surface of the cover body 10 over the extending direction of the joint 2a between the caps 2 and 2, so that the manufacturing cost is reduced. Can be reduced. Furthermore, since the first and second protrusions 20 and 30 having different shapes can be formed separately from each other, compared to the case where the first and second protrusions 20 and 30 having different shapes are continuously formed. Easy to manufacture.
Further, since the cover body 10 and the first and second protrusions 20 and 30 are integrally formed and have elasticity, for example, there is a step between the adjacent headboards 2 and 2. Even when a construction error occurs, the cover main body 20 and the first and second protrusions 20 and 30 can be deformed in accordance with the construction error. Can be absorbed reliably.
In addition, the cover main body 10 and the first and second ridges 20 and 30 are formed integrally and have elasticity, and thus the first and second ridges. Since 20 and 30 are intermittently arranged at intervals from each other, the cover main body 10 can be deformed so that the cover main body 10 is widened. It is easy to attach when attaching to the connecting part between each other.

次に、以上のような笠木ジョイントカバー１を用いて、長さ方向に沿って隣り合う笠木２，２同士を接続する笠木２の接続構造について説明する。 Next, the connection structure of the headboard 2 which connects the headboards 2 and 2 adjacent along the length direction using the headboard joint cover 1 as described above will be described.

前記笠木ジョイントカバー１は、図１〜図７に示すように、前記第１および第２突条部２０，３０を、前記隣り合う笠木２，２間の目地部２ａに差し込むとともに、前記第１突条部２０の突出部２１を、前記隣り合う笠木２，２の双方の端部の裏面に当接させるようにして、前記隣り合う笠木２，２同士の接続部分に設けられている。
また、前記折り返し部１３も、前記隣り合う笠木２，２の両側面の下端部に引っ掛けられている。 As shown in FIGS. 1 to 7, the headboard joint cover 1 inserts the first and second protrusions 20 and 30 into the joint portion 2 a between the adjacent headboards 2 and 2, and the first The protruding portion 21 of the ridge portion 20 is provided at a connecting portion between the adjacent headboards 2, 2 so as to contact the back surfaces of both ends of the adjacent headboards 2, 2.
Further, the folded portion 13 is also hooked on the lower ends of both side surfaces of the adjacent caps 2 and 2.

一方、前記カバー本体１０の裏面と、前記隣り合う笠木２，２の上面との間には、図４〜図６に示すように、防水性および接着性を有するシール材６が充填されている。
なお、本実施の形態のシール材６は、例えばコーキング材が用いられているが、これに限られるものではない。
また、前記シール材６としてコーキング材が用いられているので、このシール材６は、防水性および接着性に加えて、伸縮性を有していることとなる。 On the other hand, between the back surface of the cover main body 10 and the upper surfaces of the adjacent caps 2 and 2, as shown in FIGS. 4 to 6, a sealing material 6 having waterproofness and adhesiveness is filled. .
In addition, although the caulking material is used for the sealing material 6 of this Embodiment, for example, it is not restricted to this.
Further, since a caulking material is used as the sealing material 6, the sealing material 6 has stretchability in addition to waterproofness and adhesiveness.

そして、このようなシール材６によって、前記カバー本体１０の裏面と、前記隣り合う笠木２，２の上面とを接着できるとともに、前記隣り合う笠木２，２間における防水性を高めることができる。
さらに、このように前記カバー本体１０の裏面と、前記隣り合う笠木２，２の上面とが接着されるので、前記隣り合う笠木２，２の一方が動いた場合であっても、前記カバー本体１０が、この笠木２の動きに合わせて変形し、笠木ジョイントカバー１自体がさらに外れにくくなる。 And by such a sealing material 6, while being able to adhere | attach the back surface of the said cover main body 10, and the upper surface of the said adjacent headboards 2 and 2, the waterproofness between the said adjacent headboards 2 and 2 can be improved.
Further, since the back surface of the cover main body 10 and the upper surfaces of the adjacent headboards 2 and 2 are bonded in this way, even if one of the adjacent headboards 2 and 2 moves, the cover main body 10 10 is deformed in accordance with the movement of the headboard 2, and the headboard joint cover 1 itself is more difficult to be removed.
