Description

本発明は、例えば、テラス、サンルーム、サイクルポート等の如くに建物開口部乃至壁面の前面に支柱支持によって施工設置する建物添設用独立構築物とその施工方法に関する。 The present invention is, for example, terrace, solarium, and its construction method building additionally provided for independent construct construction established by pillars supporting the front of the building opening to wall surfaces as such cycles ports.

建物開口部乃至壁面の前面に、支柱支持によって施工するテラス、サンルーム等の構築物は、支柱支持した屋根の躯体側端部を躯体に対してネジ、ボルト等の固定金具を用いて固定することによって、支柱支持と該躯体固定によって風圧の煽り荷重や積雪荷重に対する屋根の固定強度を確保するものとしてあり、下記特許文献１は、躯体への固定を、躯体側と屋根側の接続枠に相互に回動自在の湾曲面を介設して、例えば構築物設置スペースとの関係で屋根傾斜角度が異なる場合にも、該屋根傾斜角度に応じて躯体への固定をなし得るものとしたものとされる。 For structures such as terraces and solariums that are constructed by supporting columns on the front of the building opening or on the wall surface, the frame-side end of the column-supported roof must be fixed to the frame using screws, bolts, and other fixing brackets. Therefore, the fixing strength of the roof against the wind load and snow load is ensured by supporting the column and fixing the frame, and the following Patent Document 1 discloses that the frame is fixed to the frame on the frame side and the connection frame on the roof side. For example, even when the roof inclination angle is different due to the structure installation space, it can be fixed to the frame according to the roof inclination angle. The

この場合、上記のように風圧の煽り荷重や積雪荷重に対する屋根の固定強度を確保することができるが、躯体への固定にネジ、ボルト等の固定金具を用いることによって、躯体固定部位から雨水が浸入して、壁面の雨仕舞が損なわれる可能性を否定できないし、近時、住宅瑕疵担保履行法が施行されたことによって、住宅メーカーや住宅建築業者が、雨仕舞に影響する可能性のあるネジ、ボルト等の固定金具を用いた構築物の躯体への固定を忌避する傾向が生じている一方で、施主がテラス、サンルーム等の設置を望むことも多い。 In this case, it is possible to secure the roof fixing strength against wind pressure and snow load as described above, but by using fixing brackets such as screws and bolts for fixing to the frame, rainwater is released from the frame fixing site. There is no denying the possibility that the rainy performance of the wall will be damaged by intrusion, and the housing mortgage enforcement law has recently been enacted, which may cause housing manufacturers and home builders to affect the rainy performance. While there is a tendency to avoid fixing the structure to the chassis using fixing brackets such as screws and bolts, the owner often wants to install a terrace, a solarium, and the like.

従って、これら構築物を、建物開口部乃至壁面の前面に躯体固定することなく支柱支持によって独立施工する建物添設の独立構築物とする必要が生じるところ、該独立構築物とした場合に屋根の自由端と躯体との間に生じる空隙を有効且つ外観よく処理する必要が生じる。 Therefore, it becomes necessary to make these structures independent buildings attached to buildings by supporting the pillars independently without fixing the building to the building opening or the front of the wall surface. It becomes necessary to effectively and effectively treat the gap generated between the casing and the casing.

本発明による建物添接用独立構築物の施工方法は、一対の支柱を躯体から離隔した位置で該躯体の幅方向に起立配置する工程と、前記一対の支柱に前記躯体と屋根自由端との間に空隙を形成するように屋根を載置固定すると共に、板状の閉塞部材の基端側を前記屋根自由端に固定し先端側を前記躯体側に突出させることで前記空隙を閉塞して前記躯体に弾性圧接させて前記閉塞部材を基端側と先端側との間で全体に下方に凸に屈曲させる工程とを備え、前記閉塞部材の基端側の下面に下方に突出して幅方向に延びる取付部を前記屋根自由端に固定するようにしたことを特徴とする。 The construction method of the independent structure for building attachment according to the present invention includes a step of placing a pair of columns upright in a width direction of the frame at a position spaced apart from the frame, and the pair of columns between the frame and the roof free end. The roof is placed and fixed so as to form a gap in the plate, and the base end side of the plate-like closing member is fixed to the roof free end, and the tip end side is projected to the housing side to close the gap. and a step of bending the projecting downwardly across between is elastically pressed against the precursor said closure member proximal side and a distal side, projects downward in the width direction on the lower surface of the base end side of said closure member The extending attachment portion is fixed to the free end of the roof.

本発明はこれらをそれぞれ発明の要旨として上記課題解決の手段としたものである。 The present invention uses each of these as the gist of the invention as means for solving the above problems.

本発明は以上のとおりに構成したから、請求項１に記載の発明は、例えば、カーポート、サイクルポート等の屋根を支柱支持した独立構築物の設置を、その屋根自由端と躯体との間に屋根自由端の揺動撓み空隙を配置して施工する建物添設のものとし、該揺動撓み空隙によって屋根自由端の揺動を躯体非接触状態で積極的に許容し、風圧の煽り荷重や積雪荷重の負荷によって、該屋根自由端が上下方向に揺動し、該屋根自由端が躯体の壁面に接触して屋根自由端乃至躯体の壁面を損傷する可能性を解消する一方、屋根自由端と躯体との該揺動撓み空隙に、可及的に雨水の浸入を防止するように閉塞部材を配置するとともに該閉塞部材を高弾性伸張性のものとして、該閉塞部材に配置した舌状先端を躯体に対して上下方向摺動自在に弾性圧接することによって、該揺動撓み空隙を、長期の耐久性を備えて有効に且つ外観よく処理し得るようにした建物添設用独立構築物を提供することができる。 Since the present invention is configured as described above, the invention according to claim 1 can be used, for example, to install an independent structure that supports a roof such as a carport or a cycle port between a roof free end and a frame. It shall be installed in a building that is constructed with a rocking deflection gap at the free end of the roof, and the rocking deflection gap positively allows the rocking of the free end of the roof in a non-contact state with the wind pressure. While the roof free end swings in the vertical direction due to the load of snow load, the possibility that the roof free end touches the wall surface of the frame and damages the roof free end or the wall surface of the frame is eliminated, while the roof free end A tongue-shaped tip disposed on the closing member, wherein the closing member is disposed in the swinging deflection gap between the body and the housing so as to prevent the intrusion of rainwater as much as possible and the closing member is made of a highly elastic stretch Is elastically pressed against the housing so that it can slide in the vertical direction.

以下図面の例に従って本発明を更に具体的に説明すれば、図１乃至図５において１は、建物開口部乃至壁面の前面に躯体固定することなく支柱支持によって独立施工する、本例にあって、例えば、既存のカーポートを転用することによってアルミ製のテラスとした建物添設用の独立構築物であり、該独立構築物１は、上記躯体Ａとの間に屋根自由端の風圧揺動乃至積雪撓みを躯体非接触状態で許容する揺動撓み空隙Ｂを配置する一方、上記屋根自由端に該自由端長手方向に一連に配置した取付枠２と、該取付枠２に該自由端側の幅方向一端を固定して躯体Ａ側に向けて幅広に突出することによって舌状先端４３を躯体Ａに対して上下方向摺動自在に弾性圧接して上記揺動撓み空隙Ｂを閉塞する高弾性伸張性の閉塞部材を備えたものとしてある。 In the following, the present invention will be described in more detail with reference to the example of the drawings. In FIGS. 1 to 5, reference numeral 1 denotes an independent construction by supporting a column without fixing the frame to the front of the building opening or wall. For example, the building is an independent structure for building a building made of aluminum by diverting an existing carport. A swinging deflection gap B that allows bending in a non-contact state of the housing is disposed, while the mounting frame 2 is arranged in series in the longitudinal direction of the free end on the free end of the roof, and the width on the free end side of the mounting frame 2 One end of the direction is fixed, and the tongue-shaped tip 43 is elastically pressed to the housing A so as to be slidable in the vertical direction by projecting wide toward the housing A side, thereby closing the rocking deflection gap B. It is assumed that it has an occlusive closure member

本例にあって該独立構築物Ａは、アルミ押出材製の一対の支柱１１と、アルミ押出材製の屋根外枠内に同じくアルミ押出材を格子状に配置し上面に屋根パネル、例えばポリカーボネート、アルミ等の透明乃至不透明の屋根パネルを載置固定した屋根１２とを備え、一対の支柱１１を、躯体Ａから外側に離隔した位置に、該躯体Ａと平行に起立設置するとともに該一対の各支柱１１から躯体Ａ側に上向き傾斜して一端を固定した一対の梁に屋根１２を載置固定することによって、その上向き傾斜上位側先端に位置する屋根自由端を躯体Ａ側として、該一対の支柱１１によって屋根１２を支持したものとしてある。 In this example, the independent structure A includes a pair of support columns 11 made of an aluminum extruded material, and a roof panel on the upper surface, for example, polycarbonate. A roof 12 on which a transparent or opaque roof panel such as aluminum is placed and fixed, and a pair of support pillars 11 are installed upright in parallel with the housing A at positions spaced apart from the housing A, and By mounting and fixing the roof 12 on a pair of beams that are inclined upward from the column 11 to the housing A side and fixed at one end, the roof free end located at the upper end of the upwardly inclined upper side is defined as the housing A side. The roof 12 is supported by the support 11.

このとき、該一対の支柱１１の起立設置は、これを、上向き傾斜の屋根１２の奥行幅と上記揺動撓み空隙Ｂの幅の合計寸法を躯体Ａから離隔した位置として、独立構築物Ａのテラスを施工することによって、その設置状態で躯体Ａとの間に上記揺動撓み空隙Ｂを配置して、該独立構築物１を、建物に添設するように施工するも、その躯体Ａに固定したり、支持したりすることなく、上記一対の支柱１１の支持によって躯体Ａとは無関係に施工した独立設置のものとしてある。 At this time, the standing installation of the pair of support pillars 11 is performed on the terrace of the independent structure A, with the total dimension of the depth width of the upwardly inclined roof 12 and the width of the swing flexion gap B separated from the housing A. In the installation state, the above-mentioned swinging deflection gap B is arranged between the housing A and the independent structure 1 is installed so as to be attached to the building, but is fixed to the housing A. Without being supported or supported by the pair of support pillars 11 and independently constructed with respect to the housing A.

従って、該独立構築物１のテラスは、風圧の煽り荷重や積雪荷重の負荷の如くに外力を受けることによって、支柱１１支持状態で屋根１２に揺動や撓みを生じるに至るところ、該屋根１２の揺動や撓みは、上記揺動撓み空隙Ｂでなされるから、該屋根１２の揺動や撓みが生じても、屋根自由端は、躯体Ａとは無関係に上下方向に移動する結果、該屋根自由端が躯体Ａに接触するに至ることはなく、従って、該屋根１２の風圧の煽り荷重や積雪荷重による揺動や撓みを積極的に容認したものとしてある。 Accordingly, the terrace of the independent structure 1 receives an external force such as a wind load or a snow load, thereby causing the roof 12 to swing or bend in a state where the column 11 is supported. Since the rocking and bending are performed in the rocking and bending gap B, the roof free end moves in the vertical direction regardless of the frame A even if the roof 12 is rocked or bent. The free end does not come into contact with the housing A. Therefore, the roof 12 is positively permitted to swing or bend due to the wind load or snow load of the wind pressure.

本例にあって該揺動撓み空隙Ｂは、その基準幅、即ち、施工時に基準として設置する幅を８〜１２ｃｍ、本例にあっては１０ｃｍとしてあり、該１０ｃｍを屋根自由端の先端と躯体Ａの壁面まで基準の幅として、上記独立構築物１のテラスの施工を行うものとしてある。 In this example, the swinging deflection gap B has a reference width, that is, a width of 8 to 12 cm as a reference at the time of construction, and 10 cm in this example, and the 10 cm is the tip of the roof free end. As a reference width to the wall surface of the casing A, the terrace of the independent structure 1 is constructed.

該揺動撓み空隙Ｂには、閉塞部材４によって、これを被覆するように閉塞して該揺動撓み空隙Ｂに対して可及的に雨水の浸入を防止し且つ損傷することなく耐久性を有するものとしてあり、該閉塞部材４は、例えばゴム、軟質合成樹脂等の高弾性伸張性の材質による幅広の板状成形材を用いて、その幅を、上記揺動撓み空隙の基準幅の１．７〜２倍としてあり、本例にあって該閉塞部材は、その幅を１８ｃｍ強としてある。 The swinging deflection gap B is closed by the closing member 4 so as to cover it, and the swinging deflection gap B is prevented from entering rainwater as much as possible and has durability without being damaged. The closing member 4 is made of a wide plate-shaped molding material made of a highly elastic and extensible material such as rubber or soft synthetic resin, and its width is set to 1 of the reference width of the swinging deflection gap. 7 to 2 times, and in this example, the closing member has a width of 18 cm or more.

このとき、該閉塞部材４は、本例にあって、これを、エラストマーの成形材、特に押出成形材によるものとして、上記高弾性伸長性を高度に有することによって、好ましい雨水の浸入防止作用と耐久性を備えたものとしてある。該閉塞部材４は、その肉厚を、例えば、外側、即ち屋根側において１ｃｍ〜数ｍｍとし、躯体側に向けて次第に肉厚を減少して躯体側の上記舌状先端４３を、例えば数ｍｍ〜１〜２ｍｍ程度とした肉厚漸減のものとしてある。また、本例の閉塞部材４は、これに、例えばその外側に、下向き一連に一体成形して断面Ｔ字状とした嵌合条４１を備え、その幅方向中間の下面に下向き一連にＬ字状の係合条４２を配置し、その舌状先端４３の近傍に、該舌状先端４３とともに躯体に対接する対接条４４を配置したものしてあり、更に、上記Ｔ字状の嵌合条４１の外側、即ち、屋根１２の上面に向けて下降傾斜する水切突片４５を配置して一体に成形することによって、上記幅広板状のものとしてある。 At this time, the closing member 4 is in this example, and this is made of an elastomer molding material, in particular, an extrusion molding material. It is supposed to have durability. The closing member 4 has a wall thickness of, for example, 1 cm to several mm on the outside, that is, on the roof side, and gradually decreases toward the housing side so that the tongue-shaped tip 43 on the housing side is, for example, several mm. The thickness is gradually reduced to about 1 to 2 mm. Further, the closing member 4 of this example is provided with a fitting strip 41 integrally formed in a downward series and having a T-shaped cross section, for example, on the outer side thereof. In the vicinity of the tongue-shaped tip 43, a contact strip 44 that contacts the housing together with the tongue-shaped tip 43 is disposed. Further, the T-shaped fitting is provided. The wide plate-like shape is formed by arranging and integrally forming a water draining protrusion 45 that is inclined downward toward the outer side of the strip 41, that is, toward the upper surface of the roof 12.

本例における該閉塞部材４の上記取付枠２に対する固定は、これを、該取付枠２と閉塞部材４の一方に被嵌溝を、他方に嵌合条を配置し、これらの嵌合固定によって行ったものとしてあり、本例の被嵌溝２４は、これをアルミ押出材製の取付枠２の上面に、嵌合条４１は、これを閉塞部材４の上記下面にそれぞれ配置し、これらを嵌合し、必要に応じてネジ、接着等の固定手段、本例にあっては被嵌溝の下面からのネジ５を閉塞部材４の嵌合条４１に螺入することによって、その固定を行ったものとしてある。 In this example, the closing member 4 is fixed to the mounting frame 2 by arranging a fitting groove on one of the mounting frame 2 and the closing member 4 and a fitting strip on the other, The fitted groove 24 of this example is arranged on the upper surface of the mounting frame 2 made of an aluminum extruded material, and the fitting strip 41 is arranged on the lower surface of the closing member 4, respectively. The fixing means is fixed by screwing the screw 5 from the lower surface of the groove to be fitted into the fitting strip 41 of the closing member 4 in this example, if necessary. As it has been.

また、本例にあって、上記屋根自由端の上記取付枠２の躯体側に、上記閉塞部材４を突出方向中間位置で保持して該閉塞部材の突出方向を規制する中間枠乃至中間金具、本例にあっては、例えばステンレス又はアルミ押出材製とした中間金具３を備えたものとしてあり、このとき、該中間金具３への閉塞部材４の保持は、該中間金具３と閉塞部材４にそれぞれ反対方向に向けて開口する各Ｌ字上の係合条又は係合部、本例にあっては閉塞部材４において係合条４２、中間金具３において係合部３２を配置し、これら係合条４２と係合部３２の係合によって行ったものとしてある。 Further, in this example, an intermediate frame or intermediate metal fitting that holds the closing member 4 at the intermediate position in the protruding direction and restricts the protruding direction of the closing member on the housing side of the mounting frame 2 at the roof free end, In this example, the intermediate fitting 3 made of, for example, stainless steel or aluminum is provided. At this time, the closing member 4 is held on the intermediate fitting 3 by the intermediate fitting 3 and the closing member 4. In this example, the engaging strips or engaging portions on each L-shape opening in opposite directions, the engaging strip 42 in the closing member 4 and the engaging portion 32 in the intermediate fitting 3 are arranged in these examples. This is performed by the engagement of the engagement strip 42 and the engagement portion 32.

本例における取付枠２は、屋根面内側のＬ字脚条２１と、該Ｌ字脚条２１に対して起立高さをやや高くして対向配置した先端側の先端Ｌ字脚条２２と、これらＬ字脚条２１及び先端Ｌ字脚条２２によって、屋根自由端に位置する端部枠（既存のカーポートをテラスに転用した本例の独立構築物にあってカーポートとして見たときはその前枠に相当するから、該端部枠を前枠といってもよい）１３から一対のＬ字状対向突条２３を上方に突出することによって、断面Ｃ字状とした被嵌溝２４と、上記先端Ｌ字脚条２２の突端に上向き傾斜面乃至上向き曲面をなすように起立した起立固定条２５を備えたものとしてある。 The mounting frame 2 in this example includes an L-shaped leg 21 on the inner side of the roof surface, a tip-side L-shaped leg 22 on the tip side that is opposed to the L-shaped leg 21 with a slightly raised height, By these L-shaped leg 21 and the tip L-shaped leg 22, an end frame positioned at the free end of the roof (when it is viewed as a carport in an independent structure of this example in which an existing carport is diverted to a terrace) Since the end frame corresponds to the front frame, the end frame may be referred to as a front frame). The upright fixing strip 25 erected so as to form an upward inclined surface or an upward curved surface at the protruding end of the tip L-shaped leg 22 is provided.

即ち、本例にあって上記端部枠１３は、上記既存のカーポートを転用したことから、その上面に上向きの合掌連結金具を設置する引掛け係合用のリブ１４を備えているところ、該リブ１４を、上記取付枠２を固定するための連結リブとして用いるように、該リブ１４に上記Ｌ字脚条２１を引掛け係合するとともに該Ｌ字脚条２１と先端Ｌ字脚条２２を該端部枠１３の上面に載置してその配置を行ってあり、このとき、該取付枠２は、上記中間金具３を上記起立固定条２５に、例えばネジ止めすることによって、該中間金具３とともに該端部枠１３を囲繞して該端部枠１３を２面で挟持するようにして、その固定を行ったものとしてある。 That is, in the present example, the end frame 13 is provided with a hook engagement rib 14 for installing an upward joint fitting on the upper surface of the existing carport because the existing carport is diverted. The L-shaped leg 21 is hooked and engaged with the rib 14 so that the rib 14 is used as a connecting rib for fixing the mounting frame 2, and the L-shaped leg 21 and the tip L-shaped leg 22 are engaged. Is placed on the upper surface of the end frame 13, and at this time, the mounting frame 2 is attached to the intermediate fixture 3 by, for example, screwing the intermediate metal fitting 3 to the upright fixing strip 25. The end frame 13 is surrounded with the metal fitting 3 so that the end frame 13 is sandwiched between two surfaces and fixed.

本例にあって、上記中間金具３は、上記取付枠２の起立固定条２５に重合し且つ上記端部枠１３に配置した屋根下面側に向けて傾斜面乃至曲面をなす降下端部面１５に、例えば上下方向部分的に重合する上下幅広の固定部３１と、該固定部３１の上端を屋根１２面内側に屈曲して上記横向きＬ字状とした係合部３２とを備えた片仮名のフ字状をなすプレートによるものとしてあり、該中間金具３は、その固定部３１を上記取付枠２の起立固定条２５と端部枠１３の降下端部面１５に重合配置して、その係合部３２を取付枠２の起立固定条２５にネジ５止めすることによって、該取付枠２に対して該中間金具３を一体化するとともに上記固定部３１を端部枠１３の降下端部面１５をなす傾斜面乃至曲面に重合することによって、該一体化した取付枠２と中間金具３は、取付枠のＬ字脚条２１の上記リブ１４への引掛係合と、中間金具３の降下端部面１５へのネジ５止めにより、該端部枠１３を上記囲繞してその挟持を行うようにしてその固定を行ってある。従って、本例にあって取付枠２は、これを、例えば、テラスの屋根内部へ雨水が浸入する可能性が残る端部枠１３に対して直接にネジ止めする如き構造を採ることなく、その安定且つ確実な固定を行ったものとしてある。 In this example, the intermediate metal fitting 3 overlaps with the upright fixing strip 25 of the mounting frame 2 and has a descending end surface 15 that forms an inclined surface or a curved surface toward the roof lower surface side disposed on the end frame 13. Further, for example, a katakana having a fixed portion 31 with a wide vertical portion that partially overlaps in the vertical direction, and an engaging portion 32 that bends the upper end of the fixed portion 31 to the inside of the surface of the roof 12 to form the lateral L-shape. The intermediate metal fitting 3 has its fixing portion 31 superposed on the upright fixing strip 25 of the mounting frame 2 and the lower end face 15 of the end frame 13 so as to be connected to the intermediate fitting 3. By fixing the joint portion 32 to the upright fixing strip 25 of the mounting frame 2 with the screw 5, the intermediate fitting 3 is integrated with the mounting frame 2, and the fixing portion 31 is connected to the lower end surface of the end frame 13. 15 to form an integrated sample by polymerizing into an inclined surface or a curved surface. The frame 2 and the intermediate fitting 3 are attached to the end frame 13 by hooking engagement with the rib 14 of the L-shaped leg 21 of the mounting frame and fixing the screw 5 to the lower end face 15 of the intermediate fitting 3. It is fixed in such a way that it is sandwiched and enclosed. Therefore, in this example, the mounting frame 2 does not have such a structure that is directly screwed to the end frame 13 where the possibility of rainwater entering the roof of the terrace remains. It is assumed that stable and reliable fixing has been performed.

該端部枠１３に配置した取付枠２に対する上記閉塞部材４の上記幅方向一端の固定は、取付枠２の上記断面Ｃ字状の被嵌溝２４に閉塞部材４の上記Ｔ字状の嵌合条４１を嵌合固定することによって行ってあり、また、閉塞部材４の上記突出方向中間位置の保持は、上記中間金具３のＬ字状の係合部３２に閉塞部材４の上記幅方向中間の下面に下向き一連に配置したＬ字状の係合条４２を噛合せ状に係合することによって行ってあり、これにより、該閉塞部材４は、その材質における上記高弾性伸張性を利用して、舌状先端４３を躯体Ａに対して上下方向摺動自在に弾性圧接する一方、上記舌状先端４３近傍、即ち、該舌状先端４３の下位に、例えば舌状先端４３とハ字状をなすように配置した対接条４４が、該舌状先端４３を下支え状にして同様に躯体に弾性圧接することによって、上記舌状先端４３の躯体に対する上記上下摺動自在の弾性圧接を可及的に線接触としたものとしてある。 The fixing of the one end in the width direction of the closing member 4 to the mounting frame 2 disposed in the end frame 13 is performed by fitting the T-shaped fitting of the closing member 4 into the fitting groove 24 having the C-shaped cross section of the mounting frame 2. The joint 41 is fitted and fixed, and the closing position of the closing member 4 is held at the intermediate position in the protruding direction in the width direction of the closing member 4 on the L-shaped engaging portion 32 of the intermediate fitting 3. This is done by engaging L-shaped engaging strips 42 arranged in series on the lower surface of the middle in a meshed manner, whereby the closing member 4 utilizes the high elastic extensibility of the material. Then, the tongue-shaped tip 43 is elastically pressed against the casing A so as to be slidable in the vertical direction, while the tongue-shaped tip 43 is in the vicinity of the tongue-shaped tip 43, that is, below the tongue-shaped tip 43, for example. A confronting strip 44 arranged in a shape makes the tongue-shaped tip 43 a support. By elastically pressed against the building frame as is as was as much as possible in line contact with the elastic pressing universal the perpendicular sliding against skeleton of the tongue tip 43.

図６は、他の例を示すもので、閉塞部材４の上記取付枠２に対する被嵌溝２４と嵌合条４１による嵌合固定を、該被嵌溝２４を、アルミ押出材製の取付枠２の躯体側後面に躯体側を開口するように倒Ｔ字状に配置し、嵌合条４１を、閉塞部材４の下面に屋根１２側に倒Ｔ字状に突出してそれぞれ配置し、これらを嵌合することによって行うようにした例であり、このとき、取付枠２は、上記端部枠１３のリブ１４を覆うように上面に載置する載置部２６と、該載置部２６から、該端部枠１３の降下端部面１５に重合し、ネジ５によって該降下端部面１５に固定した固定部２７を備えて一体成形したものとしてあり、これによって、該取付枠２は、端部枠に直接にネジ止めするも、閉塞部材４下面に位置する降下端部面１５を固定箇所とするから、同様にテラスの屋根内部へ雨水が浸入する可能性を解消したものとしてあり、また、このように閉塞部材４の嵌合固定を、端部枠１３上に形成した垂直面をなす被嵌溝２４と閉塞部材４の屋根１２側下面の嵌合条４１の横向きの嵌合によって行い、また、閉塞部材４の舌状先端４３を該閉塞部材４から躯体Ａ側に屈曲したものとした結果、本例にあって上記中間枠乃至中間金具や上記対接条を用いることなく、該閉塞部材４の舌状先端４３を躯体Ａに対して線接触の弾性圧接を行うものとしてある。
なお、閉塞部材４の屋根１２側の端部は取付枠２の上面に位置することから水切突片の配置を省略してある。その余は上記例と変わらないので同一符合を付して重複する説明を省略する。 FIG. 6 shows another example. The fitting groove 24 and the fitting strip 41 are fitted and fixed to the mounting frame 2 of the closing member 4, and the fitting groove 24 is attached to the mounting frame made of an aluminum extruded material. 2 is arranged in an inverted T shape so as to open the casing side on the rear side of the casing side, and the fitting strip 41 is arranged on the lower surface of the closing member 4 so as to protrude in an inverted T shape on the roof 12 side, respectively. In this example, the mounting frame 2 is mounted on the upper surface so as to cover the ribs 14 of the end frame 13, and from the mounting portion 26. The fixing frame 27 is superposed on the lower end surface 15 of the end frame 13 and is integrally formed with a fixing portion 27 fixed to the lower end surface 15 with the screw 5, whereby the mounting frame 2 is Whether the lower end face 15 located on the lower surface of the closing member 4 is a fixed place, even if it is directly screwed to the end frame Similarly, it is assumed that the possibility of rainwater entering the roof of the terrace is eliminated, and the fitting groove of the closing member 4 is thus fitted into the fitting groove that forms the vertical surface formed on the end frame 13. 24 and the fitting member 41 of the lower surface on the roof 12 side of the closing member 4 is fitted sideways, and the tongue-like tip 43 of the closing member 4 is bent from the closing member 4 to the housing A side. In this example, the tongue-like tip 43 of the closing member 4 is elastically contacted with the housing A in line contact without using the intermediate frame or intermediate fitting or the contact strip.
In addition, since the edge part by the side of the roof 12 of the closure member 4 is located in the upper surface of the attachment frame 2, arrangement | positioning of the draining protrusion piece is abbreviate | omitted. Since the remainder is not different from the above example, the same reference numerals are given and redundant description is omitted.

従って、本例の独立構築物１のテラスは、閉塞部材４が屋根１２と躯体Ａ間の上記揺動撓み空隙Ｂを閉塞して、該揺動撓み空隙Ｂからの雨水の浸入を可及的に防止することができ、該雨水の浸入を完全に防止することはできないとしても、日常的な建物とテラスの出入を含めた雨天時のテラス使用に際して有効な雨仕舞を行うことができ、このとき、上記エラストマーによる幅広板状の閉塞部材４を用いたから、該揺動撓み空隙Ｂを外観よく閉塞して、独立構築物１のテラスや躯体Ａの外観を損なうこともなく、また損傷することなく長期の耐久性を備えたものとすることができる。また、風圧の煽り荷重や積雪荷重の負荷によって屋根１２に揺動や撓みが生じても、閉塞部材４の舌状先端４３は躯体Ａに固定されることなく、上下方向摺動自在に弾性圧接したものとしたから、該閉塞部材４が屋根自由端の動作に追従し、上下方向に摺動する結果、例えば硬質の部材を用いた場合のように、該閉塞部材４が損傷することもなく、また、仮に、積雪荷重の負荷で該閉塞部材４が屋根自由端から垂下がり状に変形しても、該荷重負荷がなくなれば、必要に応じて棒を用いる等して下方から該閉塞部材４を上向きに押圧する如くにするようにすれば、容易に上向きの通常状態に復帰することができる。 Therefore, in the terrace of the independent structure 1 of the present example, the closing member 4 closes the swinging deflection gap B between the roof 12 and the casing A, and intrusion of rainwater from the swinging deflection gap B is made as much as possible. Even if it is not possible to completely prevent the intrusion of the rainwater, it is possible to perform an effective rain performance when using the terrace during rainy weather, including daily access to the building and the terrace. Since the wide plate-like closing member 4 made of the elastomer is used, the swinging flexure gap B is closed with a good appearance, and the appearance of the terrace or the casing A of the independent structure 1 is not damaged and is not damaged for a long time. It can be provided with the durability of. Even if the roof 12 is swung or bent due to wind load or snow load, the tongue-like tip 43 of the closing member 4 is not fixed to the housing A and is elastically pressed in a vertically slidable manner. As a result, the closing member 4 follows the movement of the free end of the roof and slides in the vertical direction, so that the closing member 4 is not damaged as in the case of using a hard member, for example. In addition, even if the closing member 4 is deformed to hang down from the free end of the roof under the load of a snow load, if the load does not exist, the closing member 4 is used from below by using a rod as necessary. If 4 is pressed upward, the normal state can be easily restored.
