屋根延長部材6のより詳細な構造については後述する。 A more detailed structure of the roof extension member 6 will be described later.
そして、上記のような構成に対し、この実施例は、以下のような構成を備えることができる。 Then, in contrast to the above configuration, this embodiment can be provided with the following configuration.
(1)図4に示すように、屋根延長部材6は、屋根4よりも緩い勾配を有して屋根4の軒部5に接続される。
屋根4の軒部5と屋根延長部材6との接続部分31は、上面側が突当状態とされ、下面側が離間状態とされている。下面側の離間部分31aは、防火被覆材33で覆われるようにしている。
(1) As shown in FIG. 4, the roof extension member 6 has a gentler slope than the roof 4 and is connected to the eaves 5 of the roof 4.
The upper surface side of the connecting portion 31 between the eaves portion 5 of the roof 4 and the roof extension member 6 is in an abutting state, and the lower surface side is in a separated state. The separated portion 31a on the lower surface side is covered with the fireproof covering material 33.
ここで、屋根延長部材6の勾配は、屋根4の勾配よりも緩くなっていれば良い。勾配は、水平寸法10寸に対する立ち上がり寸法で表わされる。この実施例では、例えば、屋根4は、5.5寸勾配などとされ、屋根延長部材6は、3.5寸勾配などとされている。但し、屋根4や屋根延長部材6の勾配はこれに限るものではない。 Here, the slope of the roof extension member 6 may be gentler than the slope of the roof 4. The gradient is represented by a rising dimension with respect to a horizontal dimension of 10 inches. In this embodiment, for example, the roof 4 has a 5.5-inch gradient and the like, and the roof extension member 6 has a 3.5-inch gradient and the like. However, the slope of the roof 4 and the roof extension member 6 is not limited to this.
屋根4の軒部5に接続されるとは、屋根延長部材6と屋根4の軒部5の互いに近接する端面どうしが連結されて、屋根4と屋根延長部材6とが連続するように一体化されることである。 Connecting to the eaves 5 of the roof 4 means that the roof extension member 6 and the end faces of the eaves 5 of the roof 4 that are close to each other are connected to each other, and the roof 4 and the roof extension member 6 are integrated so as to be continuous. To be done.
接続部分31は、屋根4の軒部5と屋根延長部材6との互いに近接する端面(横梁14(鼻隠し材)および端枠部23(軒元梁))どうしの連結部分およびその周辺(特に、上下面)のことである。両者の端面どうしの連結には、ネジや釘やボルトなどの固定具34が用いられる。この固定具34は、軒部5と屋根延長部材6との間に無用の隙間ができないように、屋根延長部材6を軒部5の側へ引き寄せるために取付けられる。固定具34は、屋根延長部材6の側から軒部5の側へほぼ横(斜め上方向)へ向けて取付けられる。 The connecting portion 31 is a connecting portion between the eaves 5 of the roof 4 and the end faces (cross beam 14 (fascia) and end frame 23 (eave beam)) of the roof extension member 6 adjacent to each other and their surroundings (particularly). , Upper and lower surfaces). Fixtures 34 such as screws, nails, and bolts are used to connect the end faces of the two. The fixture 34 is attached to pull the roof extension member 6 toward the eaves 5 so that there is no unnecessary gap between the eaves 5 and the roof extension member 6. The fixture 34 is attached from the side of the roof extension member 6 to the side of the eaves 5 so as to be substantially lateral (obliquely upward).
更に、屋根4の軒部5と屋根延長部材6とは、上面側が、つなぎプレート35を用いて固定される。つなぎプレート35は、屋根4および屋根延長部材6の野地板15,27の上面間に設置される。つなぎプレート35は、金属製の固定金具とされる。つなぎプレート35は、屋根4の軒部5と屋根延長部材6との屈曲角度と同じ角度に屈曲されている。つなぎプレート35は、接続部分31に沿い間隔を有して複数設けられる。つなぎプレート35は、ネジや釘などの固定部材36によって上側からほぼ下へ向けて固定される。つなぎプレート35は、防水シート16,28によって上側から覆い隠される。 Further, the eaves portion 5 of the roof 4 and the roof extension member 6 are fixed on the upper surface side by using a connecting plate 35. The connecting plate 35 is installed between the upper surfaces of the field plates 15 and 27 of the roof 4 and the roof extension member 6. The connecting plate 35 is a metal fixing bracket. The connecting plate 35 is bent at the same angle as the bending angle between the eaves 5 of the roof 4 and the roof extension member 6. A plurality of connecting plates 35 are provided along the connecting portion 31 at intervals. The connecting plate 35 is fixed from the upper side to the lower side by a fixing member 36 such as a screw or a nail. The connecting plate 35 is covered from above by the waterproof sheets 16 and 28.
そして、屋根4の軒部5と屋根延長部材6とは、下面側が、軒裏接合プレート37を用いて固定される。軒裏接合プレート37は、屋根4の軒部5および屋根延長部材6の互いに近接する端面を構成する横梁14(鼻隠し材)および端枠部23(軒元梁)の下部間に設置される。軒裏接合プレート37は、金属製の固定金具とされる。軒裏接合プレート37は、屋根4の軒部5と屋根延長部材6との屈曲角度と同じ角度に屈曲されている。軒裏接合プレート37は、接続部分31に沿い間隔を有して複数設けられる。軒裏接合プレート37は、ネジや釘などの固定部材38によって下側からほぼ上へ向けて固定される。 Then, the eaves portion 5 of the roof 4 and the roof extension member 6 are fixed on the lower surface side by using the eaves back joining plate 37. The eaves back joint plate 37 is installed between the lower part of the cross beam 14 (fascia) and the end frame 23 (eave beam) forming the end faces of the eaves 5 of the roof 4 and the roof extension member 6 adjacent to each other. .. The eaves back joint plate 37 is a metal fixing bracket. The eaves back joint plate 37 is bent at the same angle as the bending angle between the eaves 5 of the roof 4 and the roof extension member 6. A plurality of eaves back joining plates 37 are provided at intervals along the connecting portion 31. The eaves back joining plate 37 is fixed from the lower side to the upper side by a fixing member 38 such as a screw or a nail.
この際、軒裏接合プレート37の先端部(軒先側の端部)には、ほぼ上方へ向けて屈曲された係止部37aを設けても良い。この係止部37aは、屋根延長部材6の仮保持部となるものである。 At this time, a locking portion 37a that is bent substantially upward may be provided at the tip end portion (end portion on the eaves tip side) of the eaves back joining plate 37. The locking portion 37a serves as a temporary holding portion for the roof extension member 6.
即ち、屋根4の軒部5に対して軒裏接合プレート37を先に取付けておくことで、屋根4の軒部5に屋根延長部材6を取付ける際に、軒裏接合プレート37の上に屋根延長部材6の軒元梁を乗せたときに、係止部37aが端枠部23(軒元梁)を係止する。これにより、屋根延長部材6を、固定具34やつなぎプレート35によって屋根4の軒部5に容易に取付けることができる。 That is, by attaching the eaves back joint plate 37 to the eaves portion 5 of the roof 4 first, when the roof extension member 6 is attached to the eaves portion 5 of the roof 4, the roof is placed on the eaves back joint plate 37. When the eaves beam of the extension member 6 is placed, the locking portion 37a locks the end frame portion 23 (eave beam). As a result, the roof extension member 6 can be easily attached to the eaves 5 of the roof 4 by the fixture 34 and the connecting plate 35.
そして、屋根4の軒部5と屋根延長部材6との接続部分31は、両者の勾配の違いにより、上面側がほぼ突当状態となり、下面側が離間状態となるが、これによって、屋根延長部材6と屋根4との上面間に、側方から見て鈍角状となる屈曲部31bが形成されると共に、屋根4の軒部5と屋根延長部材6との互いに対向する端面間には、鋭角状の隙間31cが形成される。 The connection portion 31 between the eaves 5 of the roof 4 and the roof extension member 6 is in a substantially abutting state on the upper surface side and in a separated state on the lower surface side due to the difference in the gradients of the two. A bent portion 31b having an obtuse angle when viewed from the side is formed between the upper surface of the roof 4 and the roof 4, and an acute angle is formed between the eaves 5 of the roof 4 and the end faces of the roof extension member 6 facing each other. The gap 31c is formed.
そこで、この鋭角状の隙間31cに、スペーサとして、ほぼ三角断面の角度規定部材39を介在させるようにする。三角断面の角度規定部材39を介在させることにより、屋根4に対して屋根延長部材6を容易に正確な角度に設置することが可能になる。角度規定部材39は、概略形状がほぼ三角断面となっていれば、角部などが若干欠けていても良い。三角断面の角度規定部材39は、例えば、屋根4の軒部5の端面に対して予め固定しておくのが好ましい。なお、屋根延長部材6の取付けの際には、三角断面の角度規定部材39に加えて、現地勾配調整用治具などを適宜用いるようにする。 Therefore, an angle defining member 39 having a substantially triangular cross section is interposed as a spacer in the acute-angled gap 31c. By interposing the angle defining member 39 having a triangular cross section, the roof extension member 6 can be easily installed at an accurate angle with respect to the roof 4. The angle defining member 39 may have some corners or the like missing as long as the approximate shape has a substantially triangular cross section. It is preferable that the angle defining member 39 having a triangular cross section is fixed in advance to, for example, the end surface of the eaves 5 of the roof 4. When attaching the roof extension member 6, in addition to the angle defining member 39 having a triangular cross section, a jig for adjusting a local gradient or the like is appropriately used.
三角断面の角度規定部材39は、屋根4の軒部5の端面に当接固定される第一の面と、屋根延長部材6の端面に当接固定される第二の面と、これらの面の下側に位置する第三の面との3つの面を有するものとされる。第一の面と第二の面とによって三角断面の角度規定部材39の上側に鋭角の角部が形成される。この角部は、屋根4と屋根延長部材6との上面間に形成される屈曲部31bの補角とされる。 The angle defining member 39 having a triangular cross section has a first surface that is abutted and fixed to the end surface of the eaves 5 of the roof 4, a second surface that is abutted and fixed to the end surface of the roof extension member 6, and these surfaces. It is assumed to have three faces with a third face located on the lower side. An acute-angled corner is formed on the upper side of the angle defining member 39 having a triangular cross section by the first surface and the second surface. This corner portion is used as a complementary angle of the bent portion 31b formed between the upper surface of the roof 4 and the roof extension member 6.
防火被覆材33は、接続部分31の下面側に形成される離間部分31aを塞ぐように、接続部分31の下面側の軒天井材18,26の対向する縁部間に取付けられる。防火被覆材33は、離間部分31aから屋根4や屋根延長部材6の内部に火気が入り込むのを防止するためのファイヤーストップとして機能する。防火被覆材33は、例えば、ガルバリウム鋼板(登録商標)などの耐火性を有する金属板などで構成することができる。防火被覆材33は、接続部分31または軒部5に沿って横へ連続的に延ばされる。 The fireproof covering material 33 is attached between the facing edges of the eaves ceiling materials 18 and 26 on the lower surface side of the connecting portion 31 so as to close the separating portion 31a formed on the lower surface side of the connecting portion 31. The fireproof covering material 33 functions as a fire stop for preventing fire from entering the inside of the roof 4 and the roof extension member 6 from the separated portion 31a. The fireproof coating material 33 can be made of, for example, a metal plate having fire resistance such as a galvalume steel plate (registered trademark). The fire protection covering material 33 is continuously extended laterally along the connecting portion 31 or the eaves portion 5.
また、防火被覆材33の下側には、防火被覆材33を覆い隠すように、軒天見切材41を取付けても良い。軒天見切材41は、接続部分31の下側の見栄えを整えるために設けられる。軒天見切材41は、例えば、アクリル鋼板などの加飾性を有する金属板などで構成することができる。軒天見切材41は、接続部分31または軒部5に沿って横へ連続的に延ばされる。 Further, an eaves roof cutting material 41 may be attached to the lower side of the fireproof covering material 33 so as to cover the fireproof covering material 33. The eaves roof cutting material 41 is provided to adjust the appearance of the lower side of the connecting portion 31. The eaves roof cutting material 41 can be made of, for example, a decorative metal plate such as an acrylic steel plate. The eaves roof cutting material 41 is continuously extended laterally along the connecting portion 31 or the eaves portion 5.
防火被覆材33および軒天見切材41は、ビスなどの固定部材42によって下側から上へ向けて取付けられている。 The fireproof covering material 33 and the eaves roof cutting material 41 are attached from the lower side to the upper side by a fixing member 42 such as a screw.
(2)図5に示すように、屋根延長部材6の軒先側の端部には、換気口51を有する鼻先鋼板52が取付けられても良い。 (2) As shown in FIG. 5, a nose steel plate 52 having a ventilation port 51 may be attached to the end of the roof extension member 6 on the eaves side.
屋根延長部材6の軒先側の端部は、鼻隠し材などの端枠部22とされる。この端枠部22は、上端部を野地板27に当接配置すると共に、下端部を軒天井材26(の上面)に達しない長さにすることで、端枠部22の下端と軒天井材26との間に通気部53を形成して、屋根延長部材6の内部へ屋外の空気54を取り込めるようにしても良い。 The end portion of the roof extension member 6 on the eaves side is an end frame portion 22 such as a fascia material. The upper end of the end frame portion 22 is arranged in contact with the field plate 27, and the lower end portion is set to a length that does not reach (the upper surface) of the eaves ceiling material 26, so that the lower end portion of the end frame portion 22 and the eaves ceiling are formed. A ventilation portion 53 may be formed between the material 26 and the material 26 so that the outdoor air 54 can be taken into the inside of the roof extension member 6.
この通気部53の手前側(軒先側)には、雨水などの水切りを行うと共に、通気部53への雨水の入り込みを防止するための鼻先水切55などを、通気部53の入口から離して取付けても良い。鼻先水切55は、通気経路を確保するように、通気部53とほぼ同じかそれよりも下側へ延びて通気部53を外側から覆い隠す部分を主に有している。鼻先水切55は、端枠部22の下面に下側から当接された状態で皿木ネジなどの固定部材56を用いて下側からほぼ上方へ向けて取付けられる。 On the front side (eave tip side) of the ventilation portion 53, a drainer such as a nose tip drainer 55 for draining rainwater and the like and preventing rainwater from entering the ventilation portion 53 is attached away from the entrance of the ventilation portion 53. You may. The nose tip drain 55 mainly has a portion extending substantially the same as or below the ventilation portion 53 and covering the ventilation portion 53 from the outside so as to secure a ventilation path. The nose tip drain 55 is attached to the lower surface of the end frame portion 22 from the lower side by using a fixing member 56 such as a countersunk screw in a state of being in contact with the lower surface of the end frame portion 22 from the lower side.
そして、この通気部53の奥側には、屋根延長部材6の内部への雨水などの入り込みを防止するための、防水堰板57などを設けても良い。この防水堰板57は、通気経路を確保するように、軒天井材26の上面の位置から端枠部22とほぼ平行な状態で野地板27に達しない高さでほぼ上方へ延びるものなどとされる。防水堰板57は、端枠部22の裏側(軒元側)に、端枠部22に対し通気部53の高さとほぼ同程度の間隔を有して設置される。防水堰板57はランバ材などの防水木桟58を用いて軒天井材26の上面に取付けられる。 Then, a waterproof weir plate 57 or the like may be provided on the back side of the ventilation portion 53 to prevent rainwater or the like from entering the inside of the roof extension member 6. The waterproof weir plate 57 extends substantially upward from the position of the upper surface of the eaves ceiling material 26 at a height that does not reach the field plate 27 in a state of being substantially parallel to the end frame portion 22 so as to secure a ventilation path. Will be done. The waterproof weir plate 57 is installed on the back side (eave side) of the end frame portion 22 with a distance of substantially the same as the height of the ventilation portion 53 with respect to the end frame portion 22. The waterproof weir plate 57 is attached to the upper surface of the eaves ceiling material 26 by using a waterproof wooden crosspiece 58 such as a lamba material.
そして、鼻先鋼板52は、ポーチ屋根8の先端部を雨水などから保護するために、屋根延長部材6の軒先側の端部に設けられる。鼻先鋼板52は、フッ素樹脂鋼板などの防火性を有する金属板などで構成することができる。鼻先鋼板52は、ポーチ屋根8の先端部に沿って横へ連続的に延ばされる。鼻先鋼板52は、軒天井材26の下面にネジなどの固定部材59を用いて下側からほぼ上へ向けて取付けられる。 The nose steel plate 52 is provided at the end of the roof extension member 6 on the eaves side in order to protect the tip of the porch roof 8 from rainwater and the like. The nose tip steel plate 52 can be made of a metal plate having fire resistance such as a fluororesin steel plate. The nose steel plate 52 is continuously extended laterally along the tip of the porch roof 8. The nose tip steel plate 52 is attached to the lower surface of the eaves ceiling material 26 from the lower side substantially upward by using a fixing member 59 such as a screw.
より具体的には、屋根延長部材6の端枠部22(鼻隠し材)の軒先側には、側方から見た断面形状がほぼ直角三角形状をした鼻先木桟61が取付けられる。この鼻先木桟61は、屋根延長部材6の軒先側の端部に垂直面を設けるなどのためのものである。鼻先木桟61は、屋根延長部材6を屋根4に設置したときに、斜面が垂直方向へ向くように取付けられる。 More specifically, a nose tip wooden crosspiece 61 having a substantially right-angled triangular cross section when viewed from the side is attached to the eaves side of the end frame portion 22 (fascia material) of the roof extension member 6. The nose tip wooden crosspiece 61 is for providing a vertical surface at the end of the roof extension member 6 on the eaves side. The nose tip wooden crosspiece 61 is attached so that the slope faces in the vertical direction when the roof extension member 6 is installed on the roof 4.
そして、鼻先鋼板52は、屋根延長部材6の軒先側の端面を覆う側面部62と、側面部62の下端部から屋根延長部材6の軒天井材26とほぼ平行な方向へ屈曲されて軒天井材18,26の下面に達するまで延びる底面部63とを有する側面視ほぼL字状のものとされる。 The nose steel plate 52 is bent in a direction substantially parallel to the side surface portion 62 covering the end surface of the roof extension member 6 on the eaves side and the lower end portion of the side surface portion 62 to the eaves ceiling material 26 of the roof extension member 6. It has a substantially L-shaped side view having a bottom surface portion 63 extending until it reaches the lower surface of the members 18 and 26.
鼻先鋼板52の側面部62は、上部に端枠部22(鼻隠し材)の面に沿った傾斜面62aを有すると共に、その下部に鼻先木桟61に沿った垂直面62bを形成するように途中で垂直下方へ向けて屈曲されている。側面部62の下部は、鼻先木桟61よりも下方へ延びる延長部62cとされて、端枠部22(鼻隠し材)および鼻先木桟61の下側に、空間を形成するようになっている。この空間は、延長部62cと底面部63とで囲われたものとなる。なお、鼻先水切55は、この空間内に、延長部62cや底面部63と接触しないように設置される。 The side surface portion 62 of the nose tip steel plate 52 has an inclined surface 62a along the surface of the end frame portion 22 (fascia material) at the upper portion, and forms a vertical surface 62b along the nose tip wooden crosspiece 61 at the lower portion thereof. It is bent vertically downward on the way. The lower portion of the side surface portion 62 is an extension portion 62c extending downward from the nose tip wooden crosspiece 61, and forms a space under the end frame portion 22 (fascia material) and the nose tip wooden crosspiece 61. There is. This space is surrounded by the extension portion 62c and the bottom surface portion 63. The nose tip drain 55 is installed in this space so as not to come into contact with the extension portion 62c and the bottom surface portion 63.
換気口51は、鼻先鋼板52の下側の空間の位置に形成される。この実施例では、側面部62の鼻先木桟61よりも下方へ延ばされた延長部62cにおける、鼻先水切55の手前側に位置する部分に、空間内へ向かって奥に凹む凹部62dを形成し、この凹部62dに複数の穴部やスリット部などを適宜設けることで換気口51を形成している。これにより、鼻先水切55は、換気口51と通気部53との間に上下に横切るように位置してラビリンス状のシールを形成する。 The ventilation port 51 is formed at a position in the space below the steel plate 52 at the tip of the nose. In this embodiment, a recess 62d that is recessed inward toward the inside of the space is formed in a portion of the extension portion 62c of the side surface portion 62 that extends downward from the nose tip wooden crosspiece 61 and is located on the front side of the nose tip drain 55. The ventilation port 51 is formed by appropriately providing a plurality of holes, slits, and the like in the recess 62d. As a result, the nose tip drain 55 is positioned so as to vertically cross between the ventilation port 51 and the ventilation portion 53 to form a labyrinth-like seal.
なお、屋根延長部材6の軒先側の鼻先鋼板52で覆われた鼻先木桟61および端枠部22(鼻隠し材)の部分には、ブラケット65を介して軒樋66が取付けられる。 The eaves gutter 66 is attached to the nose tip wooden crosspiece 61 and the end frame portion 22 (fascia material) covered with the nose tip steel plate 52 on the eaves side of the roof extension member 6 via the bracket 65.
(3)図5に示すように、屋根延長部材6の軒先側の端部近傍には、ポーチ柱11の上端部を取付けるための柱受部71が設けられても良い。
柱受部71の位置には、通気隙間72が形成されても良い。
(3) As shown in FIG. 5, a pillar receiving portion 71 for attaching the upper end portion of the porch pillar 11 may be provided in the vicinity of the end portion of the roof extension member 6 on the eaves side.
A ventilation gap 72 may be formed at the position of the column receiving portion 71.
ここで、柱受部71は、屋根延長部材6の内部における、軒先側のポーチ柱11を取付ける軒先側の端部近傍の位置(防水堰板57や防水木桟58よりも軒元側)に設けられる。柱受部71は、屋根4の軒部5に対して傾斜状態に設置された屋根延長部材6に対し、野地板27の下面からほぼ垂直下方へ向くように取付けられた横梁73(軒先梁)の下端部に、部分的に設置される。 Here, the pillar receiving portion 71 is located inside the roof extension member 6 at a position near the end on the eaves side where the porch pillar 11 on the eaves side is attached (on the eaves side of the waterproof weir plate 57 and the waterproof wooden crosspiece 58). It will be provided. The pillar receiving portion 71 is a cross beam 73 (eave tip beam) attached so as to face substantially vertically downward from the lower surface of the field plate 27 with respect to the roof extension member 6 installed in an inclined state with respect to the eaves 5 of the roof 4. It is partially installed at the lower end of the.
横梁73(軒先梁)は、野地板27の下面に取付けられた側面視ほぼ直角三角形状の断面を有する取付部材74の下側に取付けられる。取付部材74は、上面(斜面)が屋根延長部材6と同じ勾配になっており、横梁73(軒先梁)は、取付部材74のほぼ水平となる面(下面)に取付けられる。取付部材74および横梁73(軒先梁)は、屋根延長部材6の幅方向へほぼ連続的に延ばされる(図6)。 The cross beam 73 (eave tip beam) is attached to the lower side of the attachment member 74 having a substantially right-angled triangular cross section in the side view, which is attached to the lower surface of the field plate 27. The upper surface (slope) of the mounting member 74 has the same slope as the roof extension member 6, and the cross beam 73 (eave beam) is mounted on a substantially horizontal surface (lower surface) of the mounting member 74. The mounting member 74 and the cross beam 73 (eaves) are extended substantially continuously in the width direction of the roof extension member 6 (FIG. 6).
柱受部71は、側面視ほぼ直角三角形状の断面を有する部材で形成され、屋根延長部材6と同じ勾配の上面や、ほぼ水平な下面を有している。
ほぼ水平な下面は、ポーチ柱11(の柱本体91)の上端部とほぼ同じ大きさを有している。この水平な下面にポーチ柱11の上端部が、取付ボルト75およびナットなどによって締結固定される。
The column receiving portion 71 is formed of a member having a substantially right-angled triangular cross section in a side view, and has an upper surface having the same slope as the roof extension member 6 and a substantially horizontal lower surface.
The substantially horizontal lower surface has substantially the same size as the upper end of the porch pillar 11 (pillar body 91). The upper end of the pouch pillar 11 is fastened and fixed to the horizontal lower surface by mounting bolts 75, nuts, and the like.
即ち、図6に示すように、屋根延長部材6の枠部24の内部には、側枠部21と平行な垂木76〜78が横方向(屋根延長部材6の幅方向)に間隔を有して複数本設置されている。 That is, as shown in FIG. 6, inside the frame portion 24 of the roof extension member 6, rafters 76 to 78 parallel to the side frame portion 21 have intervals in the lateral direction (width direction of the roof extension member 6). There are multiple installations.
そして、枠部24の内部の複数本の垂木76〜78の間に亘るように横梁73(軒先梁)が設置される。横梁73(軒先梁)と交差する垂木77,78は、軒先側と軒元側に分割される。横梁73(軒先梁)の両端部は、側枠部21に隣接する垂木76(内垂木)に固定される。 Then, a cross beam 73 (eave tip beam) is installed so as to extend between the plurality of rafters 76 to 78 inside the frame portion 24. The rafters 77 and 78 that intersect the cross beam 73 (the eaves beam) are divided into an eaves side and an eaves side. Both ends of the cross beam 73 (eave beam) are fixed to the rafters 76 (inner rafters) adjacent to the side frame portion 21.
柱受部71は、横梁73(軒先梁)の両端部またはその近傍の下面に固定部材79で固定される。 The column receiving portion 71 is fixed to both ends of the cross beam 73 (the eaves beam) or the lower surface in the vicinity thereof by the fixing member 79.
更に、上記したように、柱受部71には、ポーチ柱11の上端部を取付けるための取付ボルト75が設置される。この取付ボルト75は、柱受部71から軒天井材26の下へ突出する長さでほぼ真下へ延ばされる。 Further, as described above, the pillar receiving portion 71 is provided with mounting bolts 75 for mounting the upper end portion of the pouch pillar 11. The mounting bolt 75 extends substantially downward with a length protruding from the pillar receiving portion 71 to the bottom of the eaves ceiling material 26.
この際、図7〜図9に示すように、横梁73(軒先梁)は、二枚の梁材73a,73bを、間にスペーサ73cを介して貼り合わせたものとされる。取付ボルト75は、スペーサ73cに設けた穴に挿通配置される。柱受部71は、取付ボルト75を設置した横梁73(軒先梁)に、取付ボルト75を貫通させた状態で取付けられる。 At this time, as shown in FIGS. 7 to 9, the cross beam 73 (eave tip beam) is formed by laminating two beam members 73a and 73b with a spacer 73c in between. The mounting bolt 75 is inserted and arranged in a hole provided in the spacer 73c. The column receiving portion 71 is mounted in a state where the mounting bolt 75 is passed through the cross beam 73 (the eaves tip beam) on which the mounting bolt 75 is installed.
通気隙間72は、屋根延長部材6の内部に通気性を確保するための隙間のことである。通気隙間72を確保するために、横梁73(軒先梁)の下端を、軒天井材26(の上面)に達しない長さにする。なお、野地板27と軒天井材26との間隔は、側枠部21の高さによって規定される。よって、横梁73(軒先梁)および端枠部22,23は、枠部24よりも高さが通気隙間72や通気部53などの分だけ低くなるように形成される。 The ventilation gap 72 is a gap for ensuring ventilation inside the roof extension member 6. In order to secure the ventilation gap 72, the lower end of the cross beam 73 (the eaves beam) is set to a length that does not reach the eaves ceiling material 26 (the upper surface). The distance between the field board 27 and the eaves ceiling material 26 is defined by the height of the side frame portion 21. Therefore, the cross beam 73 (eave tip beam) and the end frame portions 22 and 23 are formed so that the height is lower than that of the frame portion 24 by the amount of the ventilation gap 72, the ventilation portion 53, and the like.
この際、横梁73(軒先梁)の下端は、軒天井材18,26と平行な面にするのが好ましい。これにより、横梁73(軒先梁)の下端と軒天井材26との間に一定間隔の通気隙間72が形成される。 At this time, it is preferable that the lower end of the cross beam 73 (eave tip beam) is a surface parallel to the eaves ceiling materials 18 and 26. As a result, ventilation gaps 72 at regular intervals are formed between the lower end of the cross beam 73 (the eaves beam) and the eaves ceiling material 26.
(4)図4に示すように、屋根4の軒部5と屋根延長部材6との接続部分31の下部には、通気隙間81が形成されても良い。 (4) As shown in FIG. 4, a ventilation gap 81 may be formed in the lower part of the connecting portion 31 between the eaves portion 5 of the roof 4 and the roof extension member 6.
ここで、通気隙間81は、接続部分31の下側の位置に通気性を確保するための隙間のことである。接続部分31に屋根延長部材6の内部から屋根4の内部への通気隙間81を確保するために、屋根4および屋根延長部材6の互いに近接する端面(横梁14(鼻隠し材)および端枠部23(軒元梁))の下端を、それぞれ軒天井材18,26(の上面)に達しない長さにする。なお、野地板15,27と軒天井材18,26との間隔は、それぞれ垂木12や側枠部21の高さによって規定される。よって、横梁73(軒先梁)および端枠部22(鼻隠し材)は、垂木12や側枠部21よりも高さが通気隙間81の分だけ低くなるように形成される。これにより、軒裏接合プレート37と、防火被覆材33および軒天見切材41との間に通気隙間81が形成される。 Here, the ventilation gap 81 is a gap for ensuring ventilation at a position below the connection portion 31. In order to secure a ventilation gap 81 from the inside of the roof extension member 6 to the inside of the roof 4 in the connecting portion 31, the end faces (cross beam 14 (fascia) and end frame portion) of the roof 4 and the roof extension member 6 in close proximity to each other. The lower end of 23 (eaves) is set to a length that does not reach the eaves ceiling materials 18 and 26 (upper surface), respectively. The distance between the field boards 15 and 27 and the eaves ceiling materials 18 and 26 is defined by the heights of the rafters 12 and the side frame portions 21, respectively. Therefore, the cross beam 73 (the eaves beam) and the end frame portion 22 (fascia) are formed so that the height is lower than that of the rafters 12 and the side frame portion 21 by the amount of the ventilation gap 81. As a result, a ventilation gap 81 is formed between the eaves back joint plate 37, the fireproof coating material 33, and the eaves roof cutting material 41.
(5)図5に示すように、屋根延長部材6の下面には、軒天井材26が取付けられている。
軒天井材26は、ポーチ柱11の柱本体91を通すが、ポーチ柱11の外周に取付けられた柱カバー92は通さない大きさの開口部93を有しても良い。
(5) As shown in FIG. 5, an eaves ceiling material 26 is attached to the lower surface of the roof extension member 6.
The eaves ceiling material 26 may have an opening 93 having a size that allows the pillar body 91 of the porch pillar 11 to pass through, but does not allow the pillar cover 92 attached to the outer periphery of the pouch pillar 11 to pass through.
ここで、ポーチ柱11は、柱本体91と、柱本体91の外側を覆う柱カバー92とで構成されている。柱本体91と柱カバー92は、それぞれほぼ矩形状などの断面を有している。開口部93は、軒天井材26の軒先側におけるポーチ柱11を取付ける位置に、柱受部71を内包するように設けられる。開口部93は、ほぼ矩形状とされる。柱カバー92の上端部は、開口部93を内包した状態で、軒天井材26の下面と全周に亘ってほぼ接するように、軒先側へ向かって屋根延長部材6と同じ下り勾配の傾斜形状にカットされた傾斜部とされる。 Here, the pouch pillar 11 is composed of a pillar main body 91 and a pillar cover 92 that covers the outside of the pillar main body 91. The pillar body 91 and the pillar cover 92 each have a cross section such as a substantially rectangular shape. The opening 93 is provided so as to include the pillar receiving portion 71 at a position where the porch pillar 11 is attached on the eaves side of the eaves ceiling material 26. The opening 93 has a substantially rectangular shape. The upper end of the pillar cover 92, with the opening 93 included, has the same downward slope as the roof extension member 6 toward the eaves so as to be substantially in contact with the lower surface of the eaves ceiling material 26 over the entire circumference. It is said to be an inclined part cut into.
<作用効果>この実施例によれば、以下のような効果を得ることができる。 <Action / Effect> According to this embodiment, the following effects can be obtained.
(作用効果 1) 玄関ポーチ3では、ポーチ屋根8が、玄関2から出入りする人を、雨水や日差しから守るように機能する。この実施例の玄関ポーチ3の場合、ポーチ屋根8は、下り勾配に傾斜された屋根4の軒部5における、玄関2の上側に位置する部分に、屋根4よりも緩い勾配の屋根延長部材6を取付けるようにしている。これにより、屋根4とは異なる勾配の屋根延長部材6を有する玄関ポーチ3を得ることができる。そのため、例えば、下り勾配の屋根4は、勾配をより大きくすることができ、建物1は、屋根4の下により大きな小屋裏空間を確保できるようになる。また、屋根延長部材6は、勾配を緩くして玄関ドア2aと干渉しないようにすることができ、玄関ドア2aをスムーズに開閉できるようになる。よって、屋根4と屋根延長部材6の勾配を異ならせることで、平屋建ての建物1の機能を高めたり、設計自由度を向上したりすることができる。 (Effect 1) In the entrance porch 3, the porch roof 8 functions to protect people entering and exiting from the entrance 2 from rainwater and sunlight. In the case of the entrance porch 3 of this embodiment, the porch roof 8 is a roof extension member 6 having a slope gentler than that of the roof 4 at a portion located above the entrance 2 in the eaves portion 5 of the roof 4 inclined downward. I am trying to install. As a result, it is possible to obtain the entrance porch 3 having the roof extension member 6 having a slope different from that of the roof 4. Therefore, for example, the downhill roof 4 can have a larger slope, and the building 1 can secure a larger cabin space under the roof 4. Further, the roof extension member 6 can loosen the slope so as not to interfere with the entrance door 2a, so that the entrance door 2a can be opened and closed smoothly. Therefore, by making the slopes of the roof 4 and the roof extension member 6 different, it is possible to enhance the function of the one-story building 1 and improve the degree of freedom in design.
この際、屋根延長部材6を、予め工場で製造することで、簡単に屋根4の軒部5に設置して玄関ポーチ3を形成することができる。また、屋根4の軒部5と屋根延長部材6との間に、三角断面の桟部材を(隙間なく)介在させても良い。これにより、三角断面の桟部材によって、屋根4と屋根延長部材6との間に勾配の違いによって隙間が生じるのを防止することができる。よって、屋根4の軒部5に対し、屋根4とは勾配の異なる屋根延長部材6を、三角断面の桟部材を介して精度良く所望の角度に設置することができる。 At this time, by manufacturing the roof extension member 6 in advance at the factory, the roof extension member 6 can be easily installed on the eaves 5 of the roof 4 to form the entrance porch 3. Further, a cross-section member having a triangular cross section may be interposed between the eaves 5 of the roof 4 and the roof extension member 6 (without gaps). As a result, it is possible to prevent a gap between the roof 4 and the roof extension member 6 due to a difference in slope due to the cross-section member having a triangular cross section. Therefore, the roof extension member 6 having a slope different from that of the roof 4 can be accurately installed at a desired angle with respect to the eaves 5 of the roof 4 via the cross-section cross-section member.
そして、屋根4の軒部5と屋根延長部材6とを異なる勾配にすることで、両者の接続部分31は、上面側が突当状態となり、下面側が離間状態となる。そこで、下面側の離間部分31aを防火被覆材33で覆うようにしても良い。これにより、接続部分31の下面側の離間部分31aに対し、防火被覆材33によって離間部分31aを塞いで防火性能を与えることができる。 Then, by making the eaves portion 5 of the roof 4 and the roof extension member 6 have different slopes, the upper surface side of the connecting portion 31 between the two is in an abutting state and the lower surface side is in a separated state. Therefore, the separated portion 31a on the lower surface side may be covered with the fireproof covering material 33. As a result, the separated portion 31a on the lower surface side of the connecting portion 31 can be covered with the fireproof covering material 33 to provide fireproof performance.
(作用効果 2)屋根延長部材6の軒先側の端部には、換気口51を有する鼻先鋼板52が取付けられても良い。これにより、屋根延長部材6の軒先側の端部から鼻先鋼板52の換気口51を通して屋根延長部材6内に換気用の空気54を取り込むことができる。 (Action Effect 2) A nose steel plate 52 having a ventilation port 51 may be attached to the end of the roof extension member 6 on the eaves side. As a result, ventilation air 54 can be taken into the roof extension member 6 from the end of the roof extension member 6 on the eaves side through the ventilation port 51 of the nose steel plate 52.
(作用効果 3)玄関ポーチ3は、屋根延長部材6の軒先側に、ポーチ柱11の上端部を取付けるための柱受部71を設けても良い。これにより、屋根延長部材6の軒先側の位置に、柱受部71を用いて、ポーチ柱11を容易に設置することができる。 (Action Effect 3) The entrance porch 3 may be provided with a pillar receiving portion 71 for attaching the upper end portion of the porch pillar 11 on the eaves side of the roof extension member 6. As a result, the porch pillar 11 can be easily installed at the position on the eaves side of the roof extension member 6 by using the pillar receiving portion 71.
柱受部71の位置に通気隙間72を形成しても良い。これにより、通気隙間72を通して屋根延長部材6の軒先側に通気性を確保することができる。 A ventilation gap 72 may be formed at the position of the column receiving portion 71. As a result, ventilation can be ensured on the eaves side of the roof extension member 6 through the ventilation gap 72.
(作用効果 4)玄関ポーチ3は、屋根4の軒部5と屋根延長部材6との接続部分31の下部に通気隙間81を形成しても良い。これにより、通気隙間81を通して屋根4の軒部5と屋根延長部材6との接続部分31の間に通気性を確保することができる。 (Action Effect 4) The entrance porch 3 may form a ventilation gap 81 in the lower part of the connecting portion 31 between the eaves portion 5 of the roof 4 and the roof extension member 6. As a result, ventilation can be ensured between the eaves 5 of the roof 4 and the connecting portion 31 of the roof extension member 6 through the ventilation gap 81.
(作用効果 5)玄関ポーチ3では、屋根延長部材6の下面に軒天井材26が取付けても良い。これにより、屋根延長部材6の下面を軒天井材26で覆って、屋根延長部材6の下面を見栄え良く仕上げることができる。 (Effect 5) In the entrance porch 3, the eaves ceiling material 26 may be attached to the lower surface of the roof extension member 6. As a result, the lower surface of the roof extension member 6 can be covered with the eaves ceiling material 26, and the lower surface of the roof extension member 6 can be finished with a good appearance.
軒天井材26は、ポーチ柱11の柱本体91を通すが、ポーチ柱11の柱カバー92は通さない大きさの開口部93を有しても良い。これにより、開口部93を通して柱本体91を軒天井材26の上側へ挿入配置すると共に、開口部93を柱カバー92で塞ぐことができる。以て、軒天井材26に対し、開口部93が外部から見えないようにして、ポーチ柱11を見栄え良く設置することができる。なお、開口部93を通った柱本体91の上端部は、開口部93の位置に設置された柱受部71に取付けられる。また、柱カバー92の上端部は、屋根延長部材6の勾配とほぼ同じ角度に形成される。 The eaves ceiling material 26 may have an opening 93 having a size that allows the pillar body 91 of the porch pillar 11 to pass through, but does not allow the pillar cover 92 of the porch pillar 11 to pass through. As a result, the pillar body 91 can be inserted and arranged above the eaves ceiling material 26 through the opening 93, and the opening 93 can be closed with the pillar cover 92. Therefore, the opening 93 can be hidden from the outside with respect to the eaves ceiling material 26, and the porch pillar 11 can be installed in a good-looking manner. The upper end of the pillar body 91 that has passed through the opening 93 is attached to the pillar receiving portion 71 installed at the position of the opening 93. Further, the upper end portion of the pillar cover 92 is formed at substantially the same angle as the slope of the roof extension member 6.
