Description

本発明は、テラス屋根又はカーポート屋根等の屋根に関する。 The present invention relates to a roof such as a terrace roof or a carport roof.

テラス屋根又はカーポート屋根（以下、代表的にテラス屋根という。）の主たる構成要素は、地面に立設される支柱と、その支柱の上端部に取り付けられる屋根枠と、その屋根枠に固定される屋根板とに大別することができる。そして、屋根枠は、通常は、前枠（敷地内方の枠）及び後枠（敷地外方の枠）と、それら前枠及び後枠の間に配置され接続される垂木（両端部に配置される妻垂木を含む。）とで構成される。また、テラス屋根に設けられる雨水排水装置は、屋根板上面の後枠側の端部から後枠に設けた雨樋に流下させ、その雨樋の排水口からこれに接続されたドレンで受け、そのドレンからエルボを介して支柱に添設した縦樋により雨水を地上に排水するように構成されている。 The main components of a terrace roof or a carport roof (hereinafter, typically referred to as a terrace roof) are a column that is erected on the ground, a roof frame that is attached to the upper end of the column, and a fixed frame to the roof frame. It can be broadly divided into roof panels. And, the roof frame is usually a front frame (frame inside the site) and a rear frame (frame outside the site), and rafters arranged between the front frame and the rear frame (arranged at both ends) Including wife rafters.) In addition, the rainwater drainage device provided on the terrace roof is allowed to flow from the end of the rear frame side of the roof plate to the rain gutter provided on the rear frame, and received by the drain connected to this from the drainage port of the rain gutter, Rainwater is drained to the ground by a vertical shaft attached to the column from the drain through an elbow.

上記テラス屋根における支柱に対する屋根枠の接続構造には、次のようなものが知られている。
１）支柱の上端部にブラケット及びボルトナットにより屋根枠の垂木の一端部側を固着する構造。例えば、特許文献１。
この場合、屋根枠は支柱に対して片持ち状に支持されるが、垂木の一端部は、支柱から後方（建物から離れる方向）に突出し、従って、垂木の一端部に接続されている後枠は支柱から後方に離れているため、その後枠に設けてある雨樋、ドレンも、支柱から後方に離れた位置に設けられている。
２）支柱の上端部間に桁を架設し、その桁に屋根枠の垂木をボルトナットで接続する構造。例えば、本出願人の提案に係る特願２００５−９５２２８の明細書。
この場合、桁の上面に垂木の底面に当接する固着縁を設け、その固着縁をボルトナットにより垂木に接続するが、桁上面を垂木底面に当接する位置を変えることにより、屋根枠後端の支柱からの離間距離を任意に決めることができる。
特開平７−２５９２６３号公報 The following is known as a connection structure of the roof frame to the column in the terrace roof.
1) A structure in which one end side of the rafter of the roof frame is fixed to the upper end portion of the column by a bracket and a bolt and nut. For example, Patent Document 1.
In this case, the roof frame is supported in a cantilevered manner with respect to the column, but one end of the rafter protrudes backward (in the direction away from the building) from the column, and is therefore connected to one end of the rafter. Since it is separated rearward from the support column, the rain gutter and drain provided on the frame are also provided at a position separated rearward from the support column.
2) A structure in which a girder is installed between the upper ends of the columns and the rafters of the roof frame are connected to the girder with bolts and nuts. For example, the specification of Japanese Patent Application No. 2005-95228 related to the proposal of the present applicant.
In this case, a fixed edge that abuts the bottom surface of the rafter is provided on the top surface of the girder, and the fixed edge is connected to the rafter by a bolt and nut, but by changing the position where the top surface of the girder abuts the bottom surface of the rafter, The separation distance from the support can be arbitrarily determined.
JP 7-259263 A

狭隘な敷地にテラス屋根を設置する場合は、テラスの有効面積を可及的に大きくするため、支柱を隣地との境界に可及的に接近させて立設することが望まれる。
しかしながら、上記１）のような支柱に対する屋根枠の接続構造を採用する屋根においては、垂木の一端部側、後枠、雨樋、ドレンが支柱よりも後方に張り出している。また、縦樋も支柱の背面に取り付けられる場合が多い。従って、支柱を隣地境界に可及的に接近させて立設すると、垂木の一端部、後枠、雨樋、ドレン等が隣地に張り出してしまう。
また、上記２）のような支柱に対する屋根枠の接続構造を採用する屋根においても、垂木の端部を支柱に固着されている桁に接続したとしても、桁はあくまで垂木にボルトナットなどで固着される構造であった。そのため、後枠は桁の後方に突出するから、その後枠、その後枠に設けてある雨樋に接続されるドレン、エルボ、縦樋などが支柱よりも後方に存在することとなるため、１）と同様に、支柱を隣地境界に可及的に接近させて立設すると、隣地に張り出してしまうという問題があった。 When installing a terrace roof on a narrow site, it is desirable that the column be erected as close as possible to the boundary with the adjacent land in order to increase the effective area of the terrace as much as possible.
However, in the roof adopting the roof frame connecting structure to the column as in 1) above, the one end portion side of the rafter, the rear frame, the gutter, and the drain protrude beyond the column. In addition, the vertical gutter is often attached to the back of the column. Therefore, when the column is erected as close as possible to the boundary of the adjacent land, one end portion of the rafter, the rear frame, the gutter, the drain and the like are projected to the adjacent land.
Moreover, even in the roof adopting the roof frame connection structure to the support as in 2) above, even if the end of the rafter is connected to the girder fixed to the support, the girder is fixed to the rafter with a bolt nut or the like. It was a structure. Therefore, since the rear frame protrudes behind the girders, the drain frame, elbow, vertical gutter, etc. connected to the rear frame and the rain gutter provided on the rear frame are located behind the column. 1) Similar to the above, if the column was set up as close as possible to the border of the adjacent land, there was a problem that it protruded to the adjacent land.

さらに、テラス屋根の需要者は、敷地に余裕がある場合は、美観及び外観的な安定感を求めて、屋根枠の後端部が支柱からある程度後方に突出する形態で、支柱又は桁と垂木が接続されることを望む場合がある。
上記２）のような支柱に対する屋根枠の接続構造を採用する屋根は、１種類の屋根で、屋根枠が支柱から後方に突出しない形態の屋根と、屋根枠が支柱から後方に突出する形態の屋根を提供することが可能であるという特長を有しているが、屋根枠が支柱から後方に突出する形態にした場合は、上記のように、支柱を隣地境界に接近させる可能性に限度があるという問題があった。 In addition, if there is room on the site, the customer of the terrace roof seeks aesthetics and appearance stability, and the rear end of the roof frame protrudes to a certain extent from the support column. May want to be connected.
The roof adopting the roof frame connection structure to the column as in 2) above is one type of roof, in which the roof frame does not protrude backward from the column, and the roof frame protrudes backward from the column. Although it has the feature that it is possible to provide a roof, if the roof frame protrudes backward from the column, there is a limit to the possibility of the column approaching the adjacent boundary as described above. There was a problem that there was.

そのため、隣地に張り出すことなく支柱を隣地境界に接近させて立設することができるテラス、カーポートなどの屋根が待望されていた。
本発明は、上記の要望に応えるためになされたものである。 Therefore, a roof such as a terrace and a car port that can be erected with the column approaching the boundary of the adjacent land without projecting to the adjacent land has been expected.
The present invention has been made to meet the above demand.

図１において、５は屋根枠ＲＦの幅方向両端部に位置する垂木、すなわち、妻垂木であり、上端部付近に屋根板６の端縁を載せる屋根板載置部５１を有し、妻垂木同士の互いに対向する面の底部に互いに対向して突出する固定部５２を有する。そして、妻垂木の長手方向端部から後枠４の中空部４４の幅に相当する距離だけ垂木の長手方向中央方向に寄った位置の固定部５２の上側において、Ｌ形金属板で作られた連結金具８の一辺がビスｂ４により固着されている。 In FIG. 1, reference numeral 5 denotes rafters located at both ends in the width direction of the roof frame RF, that is, a tsum rafter, which has a roof plate placing portion 51 on which an edge of the roof plate 6 is placed in the vicinity of the upper end portion. The bottom part of the mutually opposing surface has the fixing | fixed part 52 which protrudes mutually facing. And it was made of an L-shaped metal plate on the upper side of the fixed portion 52 at a position close to the longitudinal direction central direction of the rafter by a distance corresponding to the width of the hollow portion 44 of the rear frame 4 from the longitudinal direction end portion of the wife rafter. One side of the connection fitting 8 is fixed by screws b4.

上記構成により、屋根枠ＲＦにおいては、妻垂木の端部付近の内側面に固着してある連結金具８の他辺を後枠４の中空部４４の中間壁４１０に当接させ、その垂木の固定部５２を後枠４の垂木接続壁４７に載せ、かつ、その垂木５の固定部５２及び連結金具８の他辺を後枠４の中空部４４の中間壁４１０に当接させた状態で垂木接続壁４７の下側からビスｂ２を垂木５の固定部５２にねじ込み、さらに、連結金具８の他辺からビスｂ５を中間壁４１０にねじ込んで、垂木５と後枠４とを接続する。なお、後枠４の垂木当接壁４８は、スクリュードライバーでビスｂ５をねじ込むことを可能にするため、後枠の長手方向端部において適宜切除されている。 With the above configuration, in the roof frame RF, the other side of the connection fitting 8 fixed to the inner side surface near the end of the end rafter is brought into contact with the intermediate wall 410 of the hollow portion 44 of the rear frame 4 so that the rafter In a state where the fixing portion 52 is placed on the rafter connection wall 47 of the rear frame 4 and the fixing portion 52 of the rafter 5 and the other side of the connection fitting 8 are in contact with the intermediate wall 410 of the hollow portion 44 of the rear frame 4. The screw b2 is screwed into the fixing portion 52 of the rafter 5 from the lower side of the rafter connection wall 47, and the screw b5 is screwed into the intermediate wall 410 from the other side of the coupling fitting 8 to connect the rafter 5 and the rear frame 4. The rafter abutting wall 48 of the rear frame 4 is appropriately cut off at the longitudinal end of the rear frame so that the screw b5 can be screwed with a screw driver.

図２において、４１１は後枠４の雨樋４１の長手方向端面を密閉する雨樋キャップであり、屋根板６を取り付ける前に、後枠４の中空部４４の上面壁４９にビスｂ６により固着されている。 In FIG. 2, reference numeral 411 denotes a rain gutter cap that seals the longitudinal end face of the rain gutter 41 of the rear frame 4, and is fixed to the upper surface wall 49 of the hollow portion 44 of the rear frame 4 by screws b 6 before the roof plate 6 is attached. Has been.

妻垂木を除く中間の垂木は、その後枠側端部を後枠の垂木接続壁４７に載せ、その後枠側端面を後枠の垂木当接壁４８に当接させた状態で、垂木接続壁４７からビスｂ３を固定部５２にねじ込み、さらに、垂木５の端部に予め固着されている連結金具８と同様の連結金具の他辺をビス（図示せず）により垂木当接壁４８に固着することにより、全ての垂木と後枠とが接続されている。各垂木の反対側の端部には、図示されていない前枠が既知の構造と方法により連結されている。 The intermediate rafter excluding the wife rafter has its frame end positioned on the rafter connection wall 47 of the rear frame and the frame end surface is in contact with the rafter contact wall 48 of the rear frame. Then, the screw b3 is screwed into the fixing portion 52, and the other side of the connection fitting similar to the connection fitting 8 fixed in advance to the end of the rafter 5 is fixed to the rafter abutting wall 48 with a screw (not shown). As a result, all the rafters and the rear frame are connected. A front frame (not shown) is connected to the opposite end of each rafter by a known structure and method.

上記のように構成された屋根枠ＲＦに対して、桁３は次のようにして接続される。すなわち、図１及び図２に示すように、後枠４の支柱１後方への突出量を少ない形態の屋根とする場合は、桁３を後枠４の中空部４４の真下に接近させ、固着縁３４を後枠４の桁接続壁４６に当接し、その固着縁３４からビスｂ２を桁接続壁４６にねじ込む。この場合、桁接続壁４６の上側は垂木当接壁４８と中空部４４の中間壁４１０との間に形成された中空部であり、妨害物がないので、ビスｂ２のねじ込みが容易にできる。 The girder 3 is connected to the roof frame RF configured as described above as follows. That is, as shown in FIGS. 1 and 2, when the roof of the form in which the rear frame 4 protrudes backward from the support column 1 is small, the girder 3 is brought under the hollow portion 44 of the rear frame 4 and fixed. The edge 34 abuts on the girder connection wall 46 of the rear frame 4, and the screw b <b> 2 is screwed into the girder connection wall 46 from the fixed edge 34. In this case, the upper side of the girder connection wall 46 is a hollow portion formed between the rafter abutting wall 48 and the intermediate wall 410 of the hollow portion 44, and since there is no obstruction, the screw b2 can be easily screwed.

屋根枠ＲＦの後枠４に接続された桁３は、まだ大地に立設されていない支柱１の上端部に、連結具２を介して次のようにして取り付けられる。すなわち、連結具２の雌嵌合部２３に桁３の雄嵌合部３２を桁３のあり溝３７に装着しておいたボルトｂの軸を連結具２の矩形曲面板２３ａの長孔２５に貫通し、その矩形曲面板から突出したボルトｂの軸にナットｎを軽く締め付ける。続いて、その状態で支柱を垂直状態にする。その場合、雄嵌合部３２と雌嵌合部２３が曲面対偶して円弧中心回りに回動自在であるので、支柱１を容易に垂直状態にすることができる。そして、ナットｎを完全に締め付けることにより、後枠４と桁３と支柱１が接続され、後枠４は支柱１の背面から僅かに張り出すだけである。 The girder 3 connected to the rear frame 4 of the roof frame RF is attached to the upper end portion of the support column 1 that is not yet erected on the ground through the connector 2 as follows. That is, the shaft 25 of the bolt b in which the male fitting portion 32 of the girder 3 is mounted in the groove 37 of the girder 3 in the female fitting portion 23 of the coupler 2 is the long hole 25 of the rectangular curved plate 23a of the coupler 2. The nut n is lightly tightened to the shaft of the bolt b protruding from the rectangular curved plate. Subsequently, in this state, the support column is brought into a vertical state. In that case, since the male fitting part 32 and the female fitting part 23 are curved and can be turned around the center of the arc, the support column 1 can be easily brought into a vertical state. Then, by completely tightening the nut n, the rear frame 4, the girder 3 and the column 1 are connected, and the rear frame 4 only projects slightly from the back surface of the column 1.

従って、後枠４の雨樋４１の底部に結合されるドレン７２の支柱背面からの張り出し量が少なく、その張り出し量を一例として５ｃｍ以内に抑えることができる。そのため、図１に示されているように、隣地との境界線に厚み中心を合致させた状態で設置された塀９に支柱１を近接して立設した場合でも、後枠４、ドレン７２、縦樋７４などの排水装置を隣地に張り出すことなく設置することが可能である。よって、狭隘な土地にテラス屋根やカーポート屋根を設置する場合の有効面積を従来の屋根を用いる場合よりも拡張することができる。 Therefore, the amount of protrusion of the drain 72 coupled to the bottom of the rain gutter 41 of the rear frame 4 from the back surface of the column is small, and the amount of protrusion can be suppressed to within 5 cm as an example. Therefore, as shown in FIG. 1, even when the column 1 is erected in close proximity to the eaves 9 installed with the thickness center aligned with the boundary line with the adjacent land, the rear frame 4, the drain 72. It is possible to install a drainage device such as a vertical rod 74 without projecting to the adjacent ground. Therefore, the effective area when installing a terrace roof or a carport roof on a narrow land can be expanded as compared with the case of using a conventional roof.

本発明の好ましい実施の形態として、上記のように、後枠４の桁接続壁４６と垂木接続壁４７が後枠４の底面と同じ平面上に存在し、桁３は、その上端面に形成した固着縁３４を桁接続壁４６に固着するように構成されていることに加えて、桁３の固着縁３４と桁の上端面後部との間に垂木接続壁４７の肉厚と等しい段差が設けてある。そのため、図３，４に示すように、桁３の固着縁３４を垂木５の底面に当接させ、桁３の上端面後部の凸壁３３を後枠４の底面又は桁接続壁４６あるいは垂木接続壁４７に当接させて、その固着縁からビスｂ２を垂木５にねじ込むことにより、桁３を安定した状態で垂木５に接続することができる。これにより、支柱１を後枠４から離すこともできる。 As a preferred embodiment of the present invention, as described above, the girder connection wall 46 and the rafter connection wall 47 of the rear frame 4 exist on the same plane as the bottom surface of the rear frame 4, and the girder 3 is formed on the upper end surface thereof. In addition to being configured to fix the fixed edge 34 to the girder connection wall 46, there is a step equal to the thickness of the rafter connection wall 47 between the fixed edge 34 of the girder 3 and the rear of the upper end surface of the girder. It is provided. Therefore, as shown in FIGS. 3 and 4, the fixing edge 34 of the girder 3 is brought into contact with the bottom surface of the rafter 5, and the convex wall 33 at the rear end of the upper end surface of the girder 3 is connected to the bottom surface of the rear frame 4 or the girder connection wall 46 or rafter. The girder 3 can be connected to the rafter 5 in a stable state by abutting against the connection wall 47 and screwing the screw b2 into the rafter 5 from its fixed edge. Thereby, the support column 1 can be separated from the rear frame 4.

従って、敷地に余裕のある場合、あるいは、外観に対する希望に応じて、同一の屋根を後枠やドレンなどが支柱から後方に突出しない形態の屋根と、突出する形態の屋根とのいずれにもすることができる。従って、製造コスト低減及び部材管理軽減の効果が得られる。 Therefore, if there is room on the site, or if desired for the appearance, the same roof can be either a roof with a rear frame or drain that does not protrude backward from the column, or a roof with a protruding shape. be able to. Therefore, the effects of reducing manufacturing costs and reducing member management can be obtained.
