Description

本発明は、構造体に設置される支持部材に固定されて内部に長尺体を収容する長尺体カバー、及びその長尺体カバーを支持部材上で順次連結する施工方法に関する。   The present invention relates to a long body cover that is fixed to a support member installed in a structure and accommodates a long body therein, and a construction method that sequentially connects the long body cover on the support member.

例えば空調設備用の配管や電気ケーブル等の長尺体を建築物の屋上や外壁に配設する場合に、内部に長尺体を収容する長尺体カバーが用いられる場合がある。このような長尺体カバーを用いることで、その施工後において、良好な外観を提供するとともに紫外線や雨水等から長尺体を保護することができる。   For example, when a long body such as a pipe for an air conditioner or an electric cable is disposed on the roof or outer wall of a building, a long body cover that houses the long body may be used. By using such a long body cover, it is possible to provide a good appearance after the construction and protect the long body from ultraviolet rays, rainwater, and the like.

長尺体カバーを敷設するに当たっては、建築物に設置される支持部材に長尺体カバーを固定する場合がある。この場合において、例えば特開平１１−３０４０８１号公報（特許文献１）に開示されるように、長尺体の配設経路に沿って互いに隣接する２つの長尺体カバー〔配管カバー３２〕どうしを、共通の支持部材〔脚体３１〕を用いて当該支持部材上で連結する場合がある。特許文献１の連結構造において、隣接する２つの長尺体カバーは、互いに突き合わされた状態で複数の構成部材からなる継手〔継手装置３７＝裏当て部材４０＋側壁固定部材４２＋内側ジョイント板４３＋外側ジョイント板４４〕によって連結されている。しかし、このような連結構造では、強度的には非常に優れたものとなる一方で、部品点数が非常に多くコストや作業性の点で劣るという欠点があった。   In laying the long body cover, the long body cover may be fixed to a support member installed in the building. In this case, for example, as disclosed in Japanese Patent Application Laid-Open No. 11-304081 (Patent Document 1), two long body covers (piping covers 32) adjacent to each other along the long body arrangement path are connected to each other. In some cases, a common support member [leg 31] is used to connect on the support member. In the connection structure of Patent Document 1, two adjacent long body covers are joints composed of a plurality of constituent members in a state of being abutted with each other [joint device 37 = backing member 40 + side wall fixing member 42 + inner joint plate 43 + outer joint. Plate 44]. However, such a connection structure has a drawback that it is very excellent in strength, but has a very large number of parts and is inferior in terms of cost and workability.

そこで、本発明者らは、２つの長尺体カバーの端部どうしを重複させて当該重複部分においてボルト等の締結部材を用いて支持部材に固定することにより、特許文献１のような継手を用いることなく２つの長尺体カバーを連結することを検討した。例えば、１つ目の長尺体カバーの連結対象端部を非固定状態で支持部材上に載置した状態で、これに２つ目の長尺体カバーの連結対象端部を重ね合わせ、位置調整を行った後に締結部材を用いて両長尺体カバーを支持部材に共締めして固定するという施工方法である。このような方法は、主に低コスト化や作業性向上を図ることを狙いとするものではあるが、必要な強度も十分に確保可能であることが確認できた。   Therefore, the present inventors overlap the ends of the two long body covers and fix the joint as in Patent Document 1 by using a fastening member such as a bolt at the overlapped portion. We considered connecting two long-body covers without using them. For example, in a state where the connection target end portion of the first long body cover is placed on the support member in an unfixed state, the connection target end portion of the second long body cover is superimposed on the position. This is a construction method in which both the long body covers are fastened together and fixed to the support member using the fastening member after adjustment. Although such a method is aimed mainly at cost reduction and workability improvement, it has been confirmed that the necessary strength can be sufficiently secured.

一方で、そのような簡素化した施工方法を採用することによる新たな課題も明らかになった。すなわち、１つ目の長尺体カバーの連結対象端部を支持部材上に載置しただけの状態では、その連結対象端部が未だ固定されていないため、作業中に何らかの外力が作用した場合に支持部材から脱落する可能性がある。このような事態が生じた場合には、１つ目の長尺体カバーの連結対象端部を再度支持部材上に載置しなければならなくなるため、必ずしも作業性が十分に向上するとは言い切れなかった。   On the other hand, the new subject by adopting such a simplified construction method became clear. In other words, when the end of the first long body cover is simply placed on the support member, the end of the connection is not yet fixed, and any external force is applied during the work. There is a possibility of falling off from the support member. When such a situation occurs, the connection target end of the first elongate body cover must be placed again on the support member, and it is not necessarily said that the workability is sufficiently improved. There wasn't.

特開平１１−３０４０８１号公報Japanese Patent Laid-Open No. 11-304081

そこで、支持部材上で順次連結する場合に、低コスト化を図りつつ作業性も十分に向上させることが可能な長尺体カバーの実現が望まれる。また、低コスト化を図りつつ連結作業の作業性も十分に向上させることが可能な長尺体カバーの施工方法の実現が望まれる。   Therefore, it is desired to realize a long body cover that can sufficiently improve workability while achieving cost reduction when sequentially connecting on a support member. Moreover, realization of the construction method of the long body cover which can fully improve the workability | operativity of a connection operation | work while achieving cost reduction is desired.

本発明に係る長尺体カバーは、
構造体に設置される支持部材に固定されて内部に長尺体を収容する長尺体カバーであって、
長尺体配設経路に沿って延びて互いに対面する状態に連結された一対の側壁部材を含むカバー本体部を備え、
前記一対の側壁部材のそれぞれは、前記長尺体配設経路に沿う少なくとも両端部において前記支持部材に載置される状態で内向きに延出する延出板部を含み、
前記一対の側壁部材のそれぞれにおける前記延出板部かつ前記長尺体配設経路に沿う両端部に、締結部材が挿通される締結部材挿通部と前記延出板部の端縁に開口する切欠部とが分かれて形成されている。 The elongated body cover according to the present invention is:
A long body cover that is fixed to a support member installed in the structure and accommodates a long body therein,
A cover main body including a pair of side wall members extending along a long body arrangement path and coupled to face each other;
Each of the pair of side wall members includes an extension plate portion that extends inwardly in a state of being placed on the support member at least at both ends along the elongated body arrangement path,
A fastening member insertion portion through which a fastening member is inserted, and a notch that opens at an end edge of the extension plate portion, at both ends along the extended plate portion and the long body arrangement path in each of the pair of side wall members. The part is formed separately.

この構成によれば、締結部材挿通部に締結部材を挿通させることで、カバー本体部と締結部材との相対的な可動範囲を締結部材挿通部の内縁と締結部材との隙間分に制限することができる。このため、カバー本体部の締結部材挿通部に締結部材を挿通させつつ当該締結部材を支持部材に位置拘束することで、支持部材に対するカバー本体部の可動範囲が制限され、外力の作用の有無によらずに支持部材からのカバー本体部の脱落を防止することができる。
一方、切欠部は側壁部材における延出板部の端縁に開口するため、当該開口部を通るスライド移動によって締結部材が切欠部に収まることが許容される。このため、先のカバー本体部の締結部材挿通部に挿通された状態で支持部材に位置拘束された締結部材に対して別のカバー本体部に形成された切欠部をスライド移動させることにより、切欠部に対する締結部材の収納状態を実現することができる。つまり、支持部材からのカバー本体部の脱落を防止するための締結部材を一旦取り外すことなく、その締結部材を用いて、２つのカバー本体部の互いに重複する端部どうしを支持部材に固定することができる。
このように、連結構造自体が簡素であることに加え、作業中における支持部材からのカバー本体部の脱落が防止されるので、長尺体カバーを支持部材上で順次連結する場合における作業性を十分に向上させることができる。複数の構成部材からなる継手が不要なので、低コスト化を図ることもできる。 According to this configuration, by inserting the fastening member through the fastening member insertion portion, the relative movable range of the cover main body portion and the fastening member is limited to the gap between the inner edge of the fastening member insertion portion and the fastening member. Can do. For this reason, by restricting the position of the fastening member to the support member while inserting the fastening member through the fastening member insertion portion of the cover main body portion, the movable range of the cover main body portion with respect to the support member is limited, and whether or not an external force is applied Regardless of this, it is possible to prevent the cover main body from falling off the support member.
On the other hand, since the notch portion opens at the edge of the extending plate portion in the side wall member, the fastening member is allowed to be accommodated in the notch portion by sliding movement through the opening portion. For this reason, the notch portion formed in another cover body portion is slid and moved relative to the fastening member that is positionally restrained by the support member while being inserted into the fastening member insertion portion of the previous cover body portion. The fastening member can be stored in the part. That is, without overlapping the fastening member for preventing the cover main body from falling off from the support member, the overlapping end portions of the two cover main body portions are fixed to the support member using the fastening member. Can do.
Thus, in addition to the simplicity of the connecting structure itself, the cover main body portion is prevented from falling off from the support member during work, so that workability when sequentially connecting the long body cover on the support member is improved. It can be improved sufficiently. Since a joint composed of a plurality of constituent members is unnecessary, the cost can be reduced.

以下、本発明に係る長尺体カバーの好適な態様について説明する。但し、以下に記載する好適な態様例によって、本発明の範囲が限定される訳ではない。   Hereinafter, the suitable aspect of the elongate body cover which concerns on this invention is demonstrated. However, the scope of the present invention is not limited by the preferred embodiments described below.

１つの態様として、前記一対の側壁部材のうちの一方における前記切欠部と他方における前記切欠部とが、前記カバー本体部における対角位置に位置するように配置されていると好適である。   As one aspect, it is preferable that the cutout portion in one of the pair of side wall members and the cutout portion in the other are disposed so as to be positioned at diagonal positions in the cover main body portion.

この構成によれば、一対の側壁部材の延出板部の両端部に形成される２つの切欠部及び２つの締結部材挿通部の関係について見ればカバー本体部が２回対称となるので、施工現場においてカバー本体部の搬入向きによらずに連結作業を行うことができる。よって、カバー本体部の向きを反転させる必要が全くなく、カバー本体部が回転対称性を有さない構成に比べて作業性をさらに向上させることができる。   According to this configuration, since the cover main body portion is symmetrical twice when viewed with respect to the relationship between the two notch portions and the two fastening member insertion portions formed at both ends of the extension plate portion of the pair of side wall members, The connecting operation can be performed on the site regardless of the direction in which the cover main body is carried. Therefore, there is no need to reverse the direction of the cover main body, and the workability can be further improved compared to a configuration in which the cover main body does not have rotational symmetry.

１つの態様として、前記切欠部が、前記長尺体配設経路に略直交する状態で前記延出板部の内側端縁に開口する略Ｕ字状に形成されていると好適である。   As one aspect, it is preferable that the notch is formed in a substantially U shape that opens to the inner edge of the extension plate in a state substantially orthogonal to the elongated body disposition path.

この構成によれば、延出板部が、略Ｕ字状の切欠部の互いに対向する内縁よりも長尺体配設経路の両側に位置する部分を有するので、長尺体配設経路に概ね沿う方向におけるカバー本体部の位置ずれを抑制することができる。よって、２つのカバー本体部の重複部分にそれぞれ形成される締結部材用の挿通部の一方が延出板部の端縁に開口する切欠部である場合でも、連結後における抜け止めを図ることができる。   According to this configuration, the extending plate portion has portions located on both sides of the elongated body arrangement path rather than the mutually opposing inner edges of the substantially U-shaped notch, so that the elongated body arrangement path is generally The positional deviation of the cover main body in the direction along it can be suppressed. Therefore, even when one of the insertion portions for the fastening member respectively formed in the overlapping portion of the two cover main body portions is a cutout portion opened at the end edge of the extension plate portion, it is possible to prevent the connection after the connection. it can.

を含む。 The construction method of the long cover according to the present invention is as follows:
It is a construction method of a long body cover that sequentially connects a long body cover that accommodates a long body inside on a support member installed in the structure,
Preparing a long body cover having any one of the above-described configurations as the first long body cover and the second long body cover;
The first fastening member is inserted into one fastening member insertion portion located at the extending direction side end portion along the elongated body disposition path in the first elongated body cover, and is not fastened. Temporarily fixing the first elongated body cover to the support member with the first fastening member of
In such a manner that the first fastening member in the unfastened state is accommodated in one notch portion located at an existing direction side end portion along the long body arrangement path in the second long body cover, Installing the second elongate body cover by sliding;
The first fastening member is completely fastened, and the second fastening is performed at the fastening member insertion portion or the other one notch portion located at the existing direction side end portion of the second elongated body cover. A step of inserting a member and completely fastening the first long cover to the support member;
including.

この構成によれば、上述した各構成の長尺体カバーを用いて、低コスト化を図りつつ連結作業の作業性も十分に向上させることができる。つまり、締結部材挿通部に挿通される第１の締結部材を用いて第１の長尺体カバーを支持部材に仮止めすることで、外力の作用の有無によらずに、施工中における支持部材からの第１の長尺体カバーの脱落を防止することができる。その際、第１の締結部材は未締結状態であるので、支持部材と第１の長尺体カバーの延出板部との間の隙間に第２の長尺体カバーの延出板部をスライド移動させて重複させることができ、さらに切欠部に第１の締結部材を収めて収納状態を実現することができる。その後、第２の長尺体カバーにおける既設方向側端部に位置している締結部材挿通部又は他の１つの切欠部に第２の締結部材を挿通させるとともに、２つの締結部材を完全締結させることで、２つの長尺体カバーを適切に連結しつつ支持部材に固定することができる。
このように、連結構造自体が簡素であることに加え、作業中における支持部材からのカバー本体部の脱落が防止されるので、長尺体カバーを支持部材上で順次連結する場合における作業性を十分に向上させることができる。複数の構成部材からなる継手が不要なので、低コスト化を図ることもできる。 According to this configuration, it is possible to sufficiently improve the workability of the connection work while reducing the cost by using the long body cover having each configuration described above. In other words, the first elongate body cover is temporarily fixed to the support member using the first fastening member that is inserted into the fastening member insertion portion, so that the support member during construction can be used regardless of the presence or absence of an external force. It is possible to prevent the first elongate body cover from falling off. At that time, since the first fastening member is not fastened, the extension plate portion of the second long body cover is placed in the gap between the support member and the extension plate portion of the first long body cover. They can be slid and overlapped, and the first fastening member can be housed in the notch to realize the storage state. Thereafter, the second fastening member is inserted into the fastening member insertion portion or the other one notch portion located at the end portion on the existing direction side of the second elongated body cover, and the two fastening members are completely fastened. Thereby, it can fix to a support member, connecting two elongate body covers appropriately.
Thus, in addition to the simplicity of the connecting structure itself, the cover main body portion is prevented from falling off from the support member during work, so that workability when sequentially connecting the long body cover on the support member is improved. It can be improved sufficiently. Since a joint composed of a plurality of constituent members is unnecessary, the cost can be reduced.

〔第１の実施形態〕
本発明に係る長尺体カバー及びその施工方法の第１の実施形態について、図面を参照して説明する。図１に示すように、本実施形態に係る長尺体カバー１は、構造体９に設置される支持部材４０に固定されて内部に長尺体８を収容するためのものである。長手方向に延びる長尺体８が配設される経路である長尺体配設経路Ｐに沿って複数の長尺体カバー１が並べて配置され、これら複数の長尺体カバー１によって長尺体ダクトが構成される。この長尺体ダクトは、意匠性の向上が図られた化粧ダクトであって良い。 [First Embodiment]
1st Embodiment of the elongate body cover which concerns on this invention, and its construction method is described with reference to drawings. As shown in FIG. 1, the long body cover 1 according to this embodiment is fixed to a support member 40 installed in the structure 9 and accommodates the long body 8 therein. A plurality of elongate body covers 1 are arranged side by side along a elongate body arrangement path P, which is a path where an elongate body 8 extending in the longitudinal direction is arranged. A duct is constructed. This long duct may be a decorative duct with improved design.

本実施形態に係る長尺体カバー１は、以下の点によって特徴付けられる。すなわち、長尺体カバー１は、長尺体配設経路Ｐに沿って延びて互いに対面する状態に連結された一対の側壁部材１１を含むカバー本体部１０を備える。一対の側壁部材１１のそれぞれは、長尺体配設経路Ｐに沿う少なくとも両端部Ｅにおいて支持部材４０に載置される状態で内向きに延出する下側延出板部１２を含む。さらに、一対の側壁部材１１のそれぞれにおける下側延出板部１２かつ長尺体配設経路Ｐに沿う両端部Ｅに、第一挿通孔２１と切欠部２５とが分かれて形成されている。   The elongate body cover 1 which concerns on this embodiment is characterized by the following points. That is, the long body cover 1 includes a cover main body portion 10 including a pair of side wall members 11 that extend along the long body arrangement path P and are connected to face each other. Each of the pair of side wall members 11 includes a lower extension plate portion 12 that extends inward in a state of being placed on the support member 40 at least at both end portions E along the elongated body arrangement path P. Further, the first insertion hole 21 and the cutout portion 25 are separately formed at both end portions E along the lower extension plate portion 12 and the long body arrangement path P in each of the pair of side wall members 11.

これにより、長尺体配設経路Ｐに沿って所定間隔で断続的に設置される複数の支持部材４０上で長尺体カバー１を順次連結する場合に、低コスト化を図りつつ作業性も十分に向上させることが可能となっている。以下、本実施形態に係る長尺体カバー１及びその施工方法について、詳細に説明する。   Accordingly, when the long body cover 1 is sequentially connected on the plurality of support members 40 that are intermittently installed at predetermined intervals along the long body arrangement path P, the workability can be reduced while reducing the cost. It is possible to improve sufficiently. Hereinafter, the elongate body cover 1 which concerns on this embodiment, and its construction method are demonstrated in detail.

なお、以下の説明では、便宜上、構造体９における支持部材４０の設置面に直交する方向を基準として上下方向を定義するものとする。すなわち、前記設置面に直交する方向に沿う構造体９側を「下側」と表し、構造体９とは反対側（天蓋３０側）を「上側」と表す。長尺体カバー１における「下側」は支持部材４０によって支持される「被支持側」でもあり、「上側」は支持部材４０によって支持されない「非支持側」でもある。また、長尺体配設経路Ｐに沿う方向を「ダクト長手方向」と表す場合があり、それに直交する方向を「ダクト幅方向」と表す場合がある。また、以下の説明で参照する図面においては、図示の容易化や理解の容易化等の観点から、縮尺や上下左右の寸法比率等が実際の製品とは異なる場合がある。   In the following description, for the sake of convenience, the vertical direction is defined with reference to the direction perpendicular to the installation surface of the support member 40 in the structure 9. That is, the structure 9 side along the direction orthogonal to the installation surface is represented as “lower”, and the side opposite to the structure 9 (canopy 30 side) is represented as “upper”. The “lower side” in the long body cover 1 is also a “supported side” supported by the support member 40, and the “upper side” is also a “non-support side” not supported by the support member 40. In addition, a direction along the long body arrangement path P may be expressed as a “duct longitudinal direction”, and a direction orthogonal thereto may be expressed as a “duct width direction”. In the drawings referred to in the following description, the scale, the vertical / left / right dimensional ratio, and the like may be different from those of an actual product from the viewpoints of easy illustration and easy understanding.

図１に示すように、本実施形態に係る長尺体カバー１は、カバー本体部１０と天蓋３０とを備えている。構造体９に設置される支持部材４０に上側からカバー本体部１０が着脱可能に取り付けられ、そのカバー本体部１０に上側から天蓋３０が着脱可能に取り付けられる。ここで、構造体９は、建築物の構造体であり、例えば屋根、壁、柱、土台、及び床等（外に露出する屋根や外壁等が特に好ましい）が例示される。カバー本体部１０と天蓋３０とが互いに固定された状態で、それらの内部に、長尺体８を収容する空間（長尺体収容空間）が形成される。長尺体８は、例えば線状体、管状体、及び帯状体等の、一方向に延びる長尺状の構造を有するものである。このような長尺体８としては、具体的には、例えば空調装置用の冷媒配管、給排水用の配管、電気ケーブル等が例示される（断熱層や絶縁層等の機能層が一体化されていても良い）。   As shown in FIG. 1, the elongated body cover 1 according to the present embodiment includes a cover main body 10 and a canopy 30. The cover main body 10 is detachably attached to the support member 40 installed in the structure 9 from above, and the canopy 30 is detachably attached to the cover main body 10 from above. Here, the structure 9 is a structure of a building, and examples thereof include a roof, a wall, a pillar, a base, a floor, and the like (a roof and an outer wall exposed to the outside are particularly preferable). In a state where the cover main body 10 and the canopy 30 are fixed to each other, a space (long body accommodating space) for accommodating the long body 8 is formed therein. The long body 8 has a long structure extending in one direction, such as a linear body, a tubular body, and a strip-shaped body. Specific examples of such a long body 8 include a refrigerant pipe for an air conditioner, a pipe for water supply / drainage, an electric cable, etc. (functional layers such as a heat insulating layer and an insulating layer are integrated. May be).

図１及び図２に示すように、カバー本体部１０は、長尺体配設経路Ｐに沿って延びて互いに対面する状態に連結された一対の側壁部材（親桁）１１を含む。カバー本体部１０は、長尺体配設経路Ｐに沿う状態で互いに対面するように配置された第一側壁部材１１Ａ及び第二側壁部材１１Ｂと、両側壁部材１１Ａ，１１Ｂどうしを連結する連結部材（子桁）１８とを含む。なお、以下の説明において、単に「側壁部材１１」と言う場合には、第一側壁部材１１Ａと第二側壁部材１１Ｂとを特に区別することなく、両者について包括的に言及しているものとする。   As shown in FIGS. 1 and 2, the cover main body 10 includes a pair of side wall members (parent girders) 11 that extend along the long body arrangement path P and are connected to face each other. The cover main body 10 is a connecting member that connects the first side wall member 11A and the second side wall member 11B, which are disposed so as to face each other in a state along the long body arrangement path P, and the side wall members 11A and 11B. (Child digit) 18 is included. In the following description, when the term “side wall member 11” is simply used, it is assumed that the first side wall member 11A and the second side wall member 11B are comprehensively referred to without particularly distinguishing them. .

側壁部材１１は、金属製の長尺状板状部材として構成され、長尺体配設経路Ｐに沿って配置されている。本実施形態では、側壁部材１１は、長尺体配設経路Ｐに沿う両端部Ｅを含むダクト長手方向の全域に亘る板状部材として構成されている。側壁部材１１は、長尺体配設経路Ｐに沿って見た場合に、その上端部及び下端部が互いに対向するように屈曲されて略Ｃ字状の形状を呈するように形成されている（図３を参照）。側壁部材１１は、その上下方向の中央部において上下方向に沿って配置される中央板部１４と、下端部において中央板部１４に対して略直交する下側延出板部１２と、上端部において中央板部１４に対して略直交する上側延出板部１６とを含む。本実施形態では、側壁部材１１は、中央板部１４と下側延出板部１２との間に設けられてこれら両方に対して傾斜する下側傾斜板部１３と、中央板部１４と上側延出板部１６との間に設けられてこれら両方に対して傾斜する上側傾斜板部１５とをさらに含む。   The side wall member 11 is configured as a metal long plate-like member, and is disposed along the long body arrangement path P.

(Hereinafter, referred to as “long body cover construction method”) will be described step by step. The long body cover construction method according to the present embodiment includes a preparation process, a temporary fixing process, a slide installation process, and a final fixing process. The preparation process starts before the temporary fixing process and ends at least before the slide installation process. The temporary fixing process, the slide installation process, and the final fixing process are executed in the order described. In the following description, it is assumed that a plurality of elongated body covers 1 are sequentially connected and further extended from a state where they are already laid to a predetermined position. The side where the long body cover 1 is already laid is referred to as “existing direction side”, and the side where the long body cover 1 is newly extended is referred to as “extension direction side”.

準備工程は、第１の長尺体カバー１（第１のカバー本体部１０）及び第２の長尺体カバー１（第２のカバー本体部１０）として、上述した長尺体カバー１（カバー本体部１０）を準備する工程である。本想定例のように複数の長尺体カバー１（カバー本体部１０）が既に所定位置まで敷設されている場合には、直近に敷設されたカバー本体部１０を第１のカバー本体部１０（以下、区別の容易化のために「１０Ａ」と表示する。）とみなすものとする。なお、この準備工程の段階では、第１のカバー本体部１０Ａの延設方向側端部Ｅｔは、載置面４１ａ上には載置されているものの、支持部材４０には未だ固定されていない状態にある。第２のカバー本体部１０（以下、区別の容易化のために「１０Ｂ」と表示する。）としては、フリーの状態の新たなカバー本体部１０を準備する。   In the preparation step, the above-described long body cover 1 (cover) is used as the first long body cover 1 (first cover main body portion 10) and the second long body cover 1 (second cover main body portion 10). This is a step of preparing the main body 10). When a plurality of elongate covers 1 (cover main body portion 10) are already laid to a predetermined position as in this assumed example, the most recently laid cover main body portion 10 is replaced with the first cover main body portion 10 ( Hereinafter, “10A” is displayed for ease of distinction.) At the stage of this preparation process, the extending direction side end Et of the first cover main body 10A is mounted on the mounting surface 41a but is not yet fixed to the support member 40. Is in a state. As the second cover main body 10 (hereinafter referred to as “10B” for ease of distinction), a new cover main body 10 in a free state is prepared.

このとき、仮に、例えば一対の側壁部材１１Ａ，１１Ｂが互いに順平行となる位置関係で連結されてカバー本体部１０が全体としての回転対称性を有さない場合には、搬入向きを誤った場合には第２のカバー本体部１０Ｂ（新たなカバー本体部１０）の向きを反転させる必要がある。これに対して本実施形態では、一対の側壁部材１１の下側延出板部１２の両端部Ｅに形成される２つの切欠部２５及び２つの第一挿通孔２１の関係に関して、カバー本体部１０は全体として回転対称（具体的には２回対称）となっている。このため、施工現場においてカバー本体部１０の搬入向きによらずに連結作業を行うことができ、作業性を向上させることができる。また、施工現場において新たなカバー本体部１０を搬入する際に、その搬入向きに注意を払う必要がないこと自体も大きな利点である。このような利点を有することは、施工現場が狭い場合やカバー本体部１０が比較的大型で大重量である場合に、特に有利となる。   At this time, for example, when the pair of side wall members 11A and 11B are connected in a positional relationship in which the pair of side wall members 11A and 11B are in parallel with each other, and the cover main body 10 does not have rotational symmetry as a whole, It is necessary to reverse the direction of the second cover body 10B (new cover body 10). On the other hand, in the present embodiment, the cover main body portion is related to the relationship between the two cutout portions 25 and the two first insertion holes 21 formed at both ends E of the lower extension plate portion 12 of the pair of side wall members 11. 10 is rotationally symmetric as a whole (specifically, two-fold symmetry). For this reason, it is possible to perform the connecting work at the construction site regardless of the direction in which the cover main body 10 is carried in, and the workability can be improved. Moreover, when carrying in the new cover main-body part 10 in a construction site, it is also a big advantage itself that it is not necessary to pay attention to the direction of carrying in. Having such an advantage is particularly advantageous when the construction site is narrow or when the cover body 10 is relatively large and heavy.

仮止め工程は、第１の長尺体カバー１における長尺体配設経路Ｐに沿う延設方向側端部Ｅｔに位置している１つの第一挿通孔２１に第１の第一締結部材５０を挿通させて、未締結状態の第１の第一締結部材５０で第１の長尺体カバー１を支持部材４０に仮止めする工程である。本実施形態では、準備工程後の状態において、第１のカバー本体部１０Ａの一対の側壁部材１１の下側延出板部１２の延設方向側端部Ｅｔには、第一挿通孔２１と切欠部２５とが１つずつ存在する（図１を参照）。これらのうちの第一挿通孔２１に、第１の第一締結部材５０（以下、区別の容易化のために「５０Ａ」と表示する。）を構成する第一ボルト５１の軸部を上下方向から挿通させる。その際、上下方向に見て第一挿通孔２１と支持部材４０（支持本体部４１）の第五挿通孔４５とが重複するように位置調整して、第一ボルト５１を第五挿通孔４５にも挿通させる。   The temporary fixing step includes a first first fastening member in one first insertion hole 21 located at the extending direction side end Et along the long body arrangement path P in the first long body cover 1. In this step, the first elongate body cover 1 is temporarily fixed to the support member 40 with the first first fastening member 50 in an unfastened state. In the present embodiment, in the state after the preparation step, the first insertion hole 21 and the extension direction side end Et of the lower extension plate 12 of the pair of side wall members 11 of the first cover main body 10A One notch portion 25 exists (see FIG. 1). The shaft part of the 1st volt | bolt 51 which comprises the 1st 1st fastening member 50 (Hereinafter, it displays as "50A" for ease of distinction.) To the 1st penetration hole 21 of these is the up-down direction. Insert through. At that time, the position of the first bolt 51 is adjusted so that the first insertion hole 21 overlaps with the fifth insertion hole 45 of the support member 40 (support body 41) when viewed in the vertical direction, and the first bolt 51 is inserted into the fifth insertion hole 45. Also let me pass through.

この仮止め工程の段階では、第一挿通孔２１及び第五挿通孔４５に挿通された第一ボルト５１には、第一ナット５２が螺合されても良いし、螺合されなくても良い。但し、第一ナット５２が第一ボルト５１に螺合される場合には、両者が下側延出板部１２及び支持本体部４１を挟んで隙間なく締結された状態（完全締結状態）とはならないように、不完全に締結される。この場合、第一ボルト５１の頭部と第一ナット５２との間の隙間が、２枚の下側延出板部１２と支持本体部４１との合計厚さ以上となるように、第一ナット５２の螺合代を調整することが好ましい。例えば図６に示すように、第一ボルト５１の先端部に、脱落しない程度の螺合代で第一ナット５２を螺合させると良い。本実施形態では、第一挿通孔２１及び第五挿通孔４５に挿通された第一ボルト５１に第一ナット５２が不完全に螺合された状態と、第一ナット５２が全く螺合されていない状態とを含めて、「未締結状態」と言う。   At the stage of this temporary fixing process, the first nut 52 may or may not be screwed into the first bolt 51 inserted through the first insertion hole 21 and the fifth insertion hole 45. . However, when the first nut 52 is screwed to the first bolt 51, what is the state in which both are fastened with no gap between the lower extension plate portion 12 and the support body portion 41 (completely fastened state)? It is concluded incompletely so that it does not become. In this case, the gap between the head of the first bolt 51 and the first nut 52 is equal to or greater than the total thickness of the two lower extension plate portions 12 and the support main body portion 41. It is preferable to adjust the screwing allowance of the nut 52. For example, as shown in FIG. 6, the first nut 52 may be screwed onto the tip portion of the first bolt 51 with a screwing allowance that does not drop off. In the present embodiment, the first nut 52 is incompletely screwed to the first bolt 51 inserted through the first insertion hole 21 and the fifth insertion hole 45, and the first nut 52 is completely screwed. It is called “unfastened state” including the state where there is no.

ここで、第一挿通孔２１は閉曲線からなる内縁２１ｅを有している。このため、その第一挿通孔２１に挿通された第一ボルト５１の、カバー本体部１０に対する相対的な可動範囲は、第一挿通孔２１の内縁２１ｅと第一ボルト５１の軸部の外縁との隙間分に制限される。一方、第一ボルト５１は第五挿通孔４５にも挿通されており、支持部材４０に対する相対的な可動範囲も同様に所定範囲内に制限される。その結果、支持部材４０に対して位置拘束された第一ボルト５１により、カバー本体部１０をも位置拘束することができ、結果的に支持部材４０に対するカバー本体部１０の可動範囲を極めて狭い範囲内に制限することができる。よって、外力の作用の有無によらずに支持部材４０からのカバー本体部１０の脱落を防止することができる。   Here, the first insertion hole 21 has an inner edge 21e formed of a closed curve. For this reason, the relative movable range of the first bolt 51 inserted through the first insertion hole 21 with respect to the cover body 10 is such that the inner edge 21e of the first insertion hole 21 and the outer edge of the shaft portion of the first bolt 51 are It is limited to the gap. On the other hand, the 1st volt | bolt 51 is penetrated by the 5th penetration hole 45, and the relative movable range with respect to the support member 40 is similarly restrict | limited to the predetermined range. As a result, it is possible to restrain the position of the cover main body 10 by the first bolt 51 that is position-constrained with respect to the support member 40, and as a result, the movable range of the cover main body 10 relative to the support member 40 is extremely narrow. Can be restricted within. Therefore, it is possible to prevent the cover main body 10 from falling off from the support member 40 regardless of whether or not an external force is applied.

スライド設置工程は、第２の長尺体カバー１における長尺体配設経路Ｐに沿う既設方向側端部Ｅｓに位置している１つの切欠部２５に未締結状態の第１の第一締結部材５０Ａが収まるように、第２の長尺体カバー１をスライド移動させて設置する工程である。仮止め工程の完了時には、第１の第一締結部材５０Ａは未締結状態にあるので、仮止めされた第１のカバー本体部１０Ａと支持部材４０との間には、下側延出板部１２の板厚分以上の隙間が存在している。また、切欠部２５は側壁部材１１における下側延出板部１２の内側端縁１２ｅに開口するため、当該開口部を通るスライド移動によって締結部材が切欠部２５に収まることが許容される。   In the slide installation process, the first first fastening that is not fastened to one notch 25 located at the existing direction side end Es along the long body arrangement path P in the second long body cover 1. In this step, the second elongated body cover 1 is slid and installed so that the member 50A can be accommodated. At the completion of the temporary fixing step, the first first fastening member 50A is in an unfastened state, so that the lower extending plate portion is between the temporarily fixed first cover main body portion 10A and the support member 40. There are more than 12 gaps. Further, since the notch 25 opens at the inner end edge 12e of the lower extension plate 12 in the side wall member 11, the fastening member is allowed to be accommodated in the notch 25 by sliding movement through the opening.

そこで、スライド設置工程では、図６及び図７に示すように、上記の隙間に第２のカバー本体部１０Ｂの第一側壁部材１１Ａの下側延出板部１２の既設方向側端部Ｅｓが入り込み、かつ、そこに形成された切欠部２５に第一ボルト５１の軸部が収まるように、第２のカバー本体部１０Ｂをダクト幅方向に沿ってスライド移動させる。その際、第２のカバー本体部１０Ｂの第二側壁部材１１Ｂの下側延出板部１２は、第１のカバー本体部１０Ａの第二側壁部材１１Ｂの下側延出板部１２の上に乗り上がるようにスライド移動する。   Therefore, in the slide installation step, as shown in FIGS. 6 and 7, the existing direction side end portion Es of the lower extension plate portion 12 of the first side wall member 11A of the second cover main body portion 10B is formed in the gap. The second cover main body portion 10B is slid along the duct width direction so that the shaft portion of the first bolt 51 fits into the cutout portion 25 formed therein. At that time, the lower extension plate portion 12 of the second side wall member 11B of the second cover main body portion 10B is placed on the lower extension plate portion 12 of the second side wall member 11B of the first cover main body portion 10A. Slide to get on.

このスライド移動により、第一側壁部材１１Ａ側において、第１のカバー本体部１０Ａの延設方向側端部Ｅｔに設けられた第一挿通孔２１と、第２のカバー本体部１０Ｂの既設方向側端部Ｅｓに設けられた切欠部２５とが、上下方向に見て重複するように配置される（図４を参照）。また、第二側壁部材１１Ｂ側において、第２のカバー本体部１０Ｂの既設方向側端部Ｅｓに設けられた第一挿通孔２１と、第１のカバー本体部１０Ａの延設方向側端部Ｅｔに設けられた切欠部２５とが、上下方向に見て重複するように配置される。第一挿通孔２１及び切欠部２５の各組は、上下方向に見てさらに第五挿通孔４５ともそれぞれ重複するように配置される。   By this sliding movement, on the first side wall member 11A side, the first insertion hole 21 provided in the extending direction side end Et of the first cover main body 10A and the existing direction side of the second cover main body 10B. The cutout portion 25 provided in the end portion Es is disposed so as to overlap when viewed in the vertical direction (see FIG. 4). Further, on the second side wall member 11B side, the first insertion hole 21 provided in the existing direction side end Es of the second cover main body portion 10B and the extending direction side end portion Et of the first cover main body portion 10A. The cutout portion 25 provided in the is arranged so as to overlap when viewed in the vertical direction. Each set of the first insertion hole 21 and the notch 25 is arranged so as to overlap with the fifth insertion hole 45 as seen in the vertical direction.

さらに、側壁部材１１が弾性変形して、第１のカバー本体部１０Ａの延設方向側端部Ｅｔに設けられた係合凹部２７に第２のカバー本体部１０Ｂの既設方向側端部Ｅｓに設けられた係合片２８が係合する。これと同時に、第１のカバー本体部１０Ａの延設方向側端部Ｅｔに設けられた係合片２８が第２のカバー本体部１０Ｂの既設方向側端部Ｅｓに設けられた係合凹部２７に係合する。これらの対応する係合片２８と係合凹部２７との各組の係合により、第１のカバー本体部１０Ａと第２のカバー本体部１０Ｂとの相対離脱移動が規制される。その結果、既に支持部材４０に仮止めされた第１のカバー本体部１０Ａと離脱規制部Ｒとの協働により、第２のカバー本体部１０Ｂの既設方向側端部Ｅｓも、支持部材４０に仮止めされる。   Further, the side wall member 11 is elastically deformed, and the engagement concave portion 27 provided in the extending direction side end Et of the first cover main body portion 10A is moved to the existing direction side end Es of the second cover main body portion 10B. The provided engagement piece 28 is engaged. At the same time, the engaging piece 28 provided at the extending direction side end Et of the first cover main body 10A is engaged with the engaging recess 27 provided at the existing direction side end Es of the second cover main body 10B. Engage with. Relative disengagement between the first cover main body portion 10A and the second cover main body portion 10B is restricted by the engagement of the corresponding sets of the engagement pieces 28 and the engagement concave portions 27. As a result, the existing cover side end Es of the second cover main body 10B is also attached to the support member 40 by the cooperation of the first cover main body 10A temporarily secured to the support member 40 and the separation restricting portion R. Temporarily fixed.

本止め工程は、第１の第一締結部材５０Ａを完全締結させるとともに、第２の長尺体カバー１における既設方向側端部Ｅｓに位置している第一挿通孔２１に第２の第一締結部材５０を挿通させて完全締結させ、第１の長尺体カバー１を支持部材４０に本止めする工程である。本止め工程では、それまで未締結状態にあった第１の第一締結部材５０Ａの第一ナット５２を（螺合されていなかった場合はその螺着後に）締め増して、完全締結状態とする。これにより、支持部材４０からの第１のカバー本体部１０Ａの脱落を防止するための第１の第一締結部材５０Ａを一旦取り外すことなく、その第１の第一締結部材５０Ａを用いて、２つのカバー本体部１０の互いに重複する端部Ｅどうしを支持部材４０に固定することができる。   In the main fastening step, the first first fastening member 50A is completely fastened, and the second first first insertion hole 21 positioned at the existing direction side end Es in the second elongated body cover 1 is second In this step, the fastening member 50 is inserted and completely fastened, and the first elongate body cover 1 is finally fixed to the support member 40. In the final fastening step, the first nut 52 of the first first fastening member 50A that has been in an unfastened state until then is tightened (after being screwed if not screwed) to a completely fastened state. . Accordingly, the first first fastening member 50A for preventing the first cover main body portion 10A from dropping off from the support member 40 is temporarily removed without removing the first first fastening member 50A. The overlapping end portions E of the two cover main body portions 10 can be fixed to the support member 40.

また、本止め工程では、図８に示すように、第二側壁部材１１Ｂ側において上下方向に互いに重複した第一挿通孔２１、切欠部２５、及び第五挿通孔４５に、第２の第一締結部材５０（以下、区別の容易化のために「５０Ｂ」と表示する。）を構成する第一ボルト５１の軸部を上下方向から挿通させる。そして、その第一ボルト５１に第一ナット５２を螺着させて、完全締結状態とする。これにより、第１のカバー本体部１０Ａの全体が２つの支持部材４０に本止めされるとともに、第２のカバー本体部１０Ｂの既設方向側端部Ｅｓが、当該２つの支持部材４０のうちの一方（延設方向側の支持部材４０）に本止めされる。   Further, in the final fastening step, as shown in FIG. 8, the first insertion hole 21, the cutout portion 25, and the fifth insertion hole 45 that overlap each other in the vertical direction on the second side wall member 11 </ b> B side are provided with the second first The shaft portion of the first bolt 51 that constitutes the fastening member 50 (hereinafter referred to as “50B” for ease of distinction) is inserted from above and below. Then, the first nut 52 is screwed onto the first bolt 51 to obtain a completely fastened state. As a result, the entire first cover main body 10 </ b> A is permanently fixed to the two support members 40, and the existing direction side end Es of the second cover main body 10 </ b> B is included in the two support members 40. One end (supporting member 40 on the extending direction side) is permanently fixed.

なお、本実施形態では、長尺体配設経路Ｐに略直交する状態で下側延出板部１２の内側端縁１２ｅに開口するＵ字状の内縁２５ｅを有するように切欠部２５が形成されている。このため、下側延出板部１２が、Ｕ字状の切欠部２５の互いに対向する内縁よりもダクト長手方向の両側に位置する部分を有することになるので、長尺体配設経路Ｐに概ね沿う方向におけるカバー本体部１０の位置ずれを抑制することができる。よって、下側延出板部１２の端縁に開口する切欠部２５を利用して２つのカバー本体部１０を支持部材４０に固定しつつ連結する場合でも、連結後における抜け止めを図ることができる。   In the present embodiment, the notch portion 25 is formed so as to have a U-shaped inner edge 25e that opens to the inner edge 12e of the lower extension plate portion 12 in a state of being substantially orthogonal to the long body arrangement path P. Has been. For this reason, since the lower extension plate part 12 has a part located in the both sides of a duct longitudinal direction rather than the mutually opposing inner edge of the U-shaped notch part 25, it is in the elongate body arrangement | positioning path | route P. The positional deviation of the cover main body portion 10 in the generally extending direction can be suppressed. Therefore, even when the two cover main body portions 10 are connected to the support member 40 by using the cutout portions 25 opened at the edge of the lower extension plate portion 12, it is possible to prevent the connection after the connection. it can.

本実施形態に係る長尺体カバー施工方法は、連結補強工程をさらに含む。連結補強工程は、長尺体配設経路Ｐに沿って互いに隣接するカバー本体部１０どうしを、側壁部材１１の中央板部１４にて連結して補強する工程である。連結補強工程では、それぞれの側壁部材１１の相対向する端部Ｅに形成された対応する第二挿通孔２２どうしの各組が正面視で重複する状態で、第二締結部材６０を構成する第二ボルト６１の軸部が挿通される。そして、その第二ボルト６１に第二ナット６２が螺合され、共締めによって両カバー本体部１０が互いに連結される。このように、本実施形態に係る長尺体カバー施工方法では、複雑な構成を有する継手を用いることなく両カバー本体部１０を連結している。このため、省部品によって低コスト化を図ることができるとともに、簡素化された連結構造によって作業性の向上を図ることもできる。   The long body cover construction method according to the present embodiment further includes a connection reinforcing step. The connection reinforcing step is a step of reinforcing the cover body portions 10 adjacent to each other along the long body arrangement path P by connecting them with the central plate portion 14 of the side wall member 11. In the connection reinforcing step, the second fastening member 60 is configured in a state where the respective pairs of the corresponding second insertion holes 22 formed at the opposite ends E of the respective side wall members 11 overlap in front view. The shaft part of the two bolts 61 is inserted. And the 2nd nut 62 is screwed together by the 2nd bolt 61, and both the cover main-body parts 10 are mutually connected by joint fastening. Thus, in the elongate body cover construction method which concerns on this embodiment, both the cover main-body parts 10 are connected, without using the joint which has a complicated structure. For this reason, the cost can be reduced by reducing the number of parts, and the workability can be improved by the simplified connection structure.

これらの各工程を、最後に敷設されるカバー本体部１０の延設方向側端部Ｅｔが目標地点に到達するまで逐次繰り返して実行する。その後、カバー本体部１０によって区画される空間に長尺体８を配置・固定するとともに、カバー本体部１０の上部開口を覆うように天蓋３０を固定することにより、長尺体ダクトの施工が完了する。   These steps are sequentially repeated until the extending direction side end Et of the cover main body 10 to be laid last finally reaches the target point. After that, the long body 8 is arranged and fixed in the space defined by the cover main body 10, and the canopy 30 is fixed so as to cover the upper opening of the cover main body 10, thereby completing the construction of the long duct. To do.

以上説明したように、本実施形態に係る長尺体カバー１及びその施工方法によれば、複雑な構成を有する継手が不要なので、低コスト化を図ることができる。また、外力の作用の有無によらずに支持部材４０からのカバー本体部１０の脱落を防止することができるので、連結構造自体が簡素であることとも合わせて、カバー本体部１０を支持部材４０上で順次連結する場合における作業性を向上させることができる。このような利点は、連結箇所が多くなるにつれてより顕著に現れる。   As described above, according to the elongate body cover 1 and the construction method thereof according to the present embodiment, a joint having a complicated configuration is unnecessary, so that the cost can be reduced. Further, the cover main body 10 can be prevented from falling off from the support member 40 regardless of whether or not an external force is applied, so that the cover main body 10 is supported by the support member 40 together with the simplicity of the connecting structure itself. It is possible to improve workability when sequentially connecting the above. Such an advantage appears more prominently as the number of connection points increases.

特に、カバー本体部１０が比較的大型で大重量である場合には、仮に支持部材４０からカバー本体部１０が脱落すれば、その大型かつ大重量のカバー本体部１０を再度支持部材４０上に載置しなければならず、作業者の負担も大きくなる。これらの点を考慮すれば、本実施形態に係る長尺体カバー１及びその施工方法は、例えば中高層ビル等の中規模ないし大規模建築物に設置される比較的大型の長尺体ダクトに適用する場合に、特に有利であると言える。但し、適用対象はそれに限定されることなく、例えば一般住宅等の小規模建築物に設置される比較的小型の長尺体ダクトに適用することももちろん可能である。   In particular, when the cover main body 10 is relatively large and heavy, if the cover main body 10 is removed from the support member 40, the large and heavy cover main body 10 is placed on the support member 40 again. It must be placed, and the burden on the operator increases. Considering these points, the long cover 1 and its construction method according to the present embodiment are applied to a relatively large long duct installed in a medium-sized or large-scale building such as a mid-high-rise building. This is particularly advantageous. However, the application target is not limited to this, and it is of course possible to apply to a relatively small long duct installed in a small-scale building such as a general house.

〔第２の実施形態〕
本発明に係る長尺体カバー及びその施工方法の第２の実施形態について、図面を参照して説明する。本実施形態では、カバー本体部１０の具体的構成が第１の実施形態とは異なっている。また、それに伴い、本止め工程の具体的内容が第１の実施形態とは一部異なっている。以下、本実施形態に係る長尺体カバー１及びその施工方法について、主に第１の実施形態との相違点について説明する。なお、特に明記しない点に関しては、第１の実施形態と同様であり、同一の符号を付して詳細な説明は省略する。 [Second Embodiment]
2nd Embodiment of the elongate body cover which concerns on this invention, and its construction method is described with reference to drawings. In the present embodiment, the specific configuration of the cover main body 10 is different from that of the first embodiment. In addition, along with this, the specific content of the final stopping process is partially different from that of the first embodiment. Hereinafter, the elongate body cover 1 according to the present embodiment and the construction method thereof will be described mainly with respect to differences from the first embodiment. Note that the points not particularly specified are the same as those in the first embodiment, and the same reference numerals are given and detailed description thereof is omitted.

図９に示すように、本実施形態では、一対の側壁部材１１Ａ，１１Ｂは、互いに順平行となる位置関係で連結されている。すなわち、一対の側壁部材１１にそれぞれ形成された２つの切欠部２５は、長尺体配設経路Ｐに沿う同じ側（本例では既設方向側）に位置するように配置されている。同様に、一対の側壁部材１１にそれぞれ形成された２つの第一挿通孔２１は、長尺体配設経路Ｐに沿う同じ側（切欠部２５とは反対側の、本例では延設方向側）に位置するように配置されている。   As shown in FIG. 9, in the present embodiment, the pair of side wall members 11 </ b> A and 11 </ b> B are connected to each other in a positional relationship that is in order parallel to each other. That is, the two notches 25 formed in the pair of side wall members 11 are arranged so as to be located on the same side (in the present example, the existing direction side) along the long body arrangement path P. Similarly, the two first insertion holes 21 respectively formed in the pair of side wall members 11 are on the same side along the elongated body disposition path P (on the side in the extending direction in this example, opposite to the notch 25). ).
