従来、面状構造体である壁体と棒状構造体である梁材との接合構造として、面状構造体の側面と棒状構造体との間に介設したブラケットを利用するものが特許文献１に開示されている。
特開２００１−１０７４５４号公報（図１） Conventionally, as a joint structure between a wall body that is a planar structure and a beam member that is a rod-like structure, a structure that uses a bracket interposed between the side surface of the planar structure and the rod-like structure is disclosed in Patent Document 1. Is disclosed.
JP 2001-107454 A (FIG. 1)

ところが、この接合構造は、ブラケット側からスクリューボルトを螺入することによりブラケットを壁体の側面に固定する構造であることから、例えば、壁体の厚さが小さい場合には、スクリューボルトの先端が壁体から突出する虞があり、場合によっては、十分な接合強度が得られない虞もある。 However, since this joining structure is a structure in which the bracket is fixed to the side surface of the wall body by screwing the screw bolt from the bracket side, for example, when the thickness of the wall body is small, the tip of the screw bolt May protrude from the wall, and in some cases, sufficient bonding strength may not be obtained.

なお、かかる問題は、面状構造体が床体や屋根（天井）であり、棒状構造体が柱である場合にも共通して当てはまる問題である。 Such a problem is also a problem that applies in common when the planar structure is a floor or a roof (ceiling) and the rod-like structure is a column.

このような観点から、本発明は、面状構造体の厚さが小さい場合あっても十分な接合強度を得ることが可能な面状構造体と棒状構造体との接合構造を提供することを課題とする。 From such a point of view, the present invention provides a bonding structure between a planar structure and a rod-shaped structure that can obtain sufficient bonding strength even when the thickness of the planar structure is small. Let it be an issue.

このような課題を解決するために創案された本発明は、面状構造体と当該面状構造体に支持される棒状構造体とを備え、前記面状構造体が、短手方向に連設された複数の長尺材により構成されており、前記棒状構造体が、その端面に取り付けられた蓋部材および隣り合う二つの前記長尺材に挟持されたブラケットを介して前記面状構造体に接合されている接合構造であって、前記棒状構造体は、対向して配置された一対のフランジと、前記両フランジの間に介在する一対のウェブとを有し、前記蓋部材は、前記棒状構造体の端面を塞ぐ蓋部と、前記両ウェブの間に挿入される挿入部とを有し、前記両ウェブおよび前記挿入部を貫通するボルトを利用して前記棒状構造体と前記蓋部材とが接合されていることを特徴とする。 Such problem of the invention which is designed to solve is provided with a rod-like structure that is supported on the planar structure and the planar structure, the planar structure, provided continuously in the lateral direction The rod-like structure is formed on the planar structure via a lid member attached to an end face thereof and a bracket sandwiched between two adjacent elongated members. It is the joining structure joined, Comprising: The said rod-shaped structure has a pair of flange arrange | positioned opposingly, and a pair of web interposed between both said flanges, The said cover member is the said rod-shaped structure The rod-like structure and the lid member having a lid portion that covers an end surface of the structure, and an insertion portion that is inserted between the webs, and using bolts that penetrate the webs and the insertion portion. Are joined .

つまり、この接合構造は、複数の長尺材をその短手方向に連設して面状構造体を構成するとともに、この面状構造体と棒状構造体との間に介設されるブラケットを隣り合う二つの長尺材で挟み込むことによって固定するものである。このようにすると、面状構造体の壁厚が薄い場合あっても十分な接合強度をもって棒状構造体を接合することが可能となる。なお、本発明においては、面状構造体には、耐力壁や間仕切り壁などの壁体、床体、屋根（天井）などが含まれ、棒状構造体には、梁材や柱材などが含まれる。 That is, in this joining structure, a plurality of long materials are connected in the short direction to form a planar structure, and a bracket interposed between the planar structure and the rod-shaped structure is provided. It is fixed by sandwiching it between two adjacent long materials. In this way, even if the wall thickness of the planar structure is thin, it becomes possible to join the rod-like structure with sufficient joining strength. In the present invention, the planar structure includes a wall such as a load-bearing wall and a partition wall, a floor, a roof (ceiling), and the like, and the rod-shaped structure includes a beam member, a column member, and the like. It is.

なお、本発明に係る接合構造においては、前記各長尺材および前記棒状構造体の少なくとも一方が、アルミニウム合金製の押出形材で構成されていてもよい。 In the joint structure according to the present invention, at least one of the long materials and the rod-like structure may be formed of an extruded shape made of an aluminum alloy.

面状構造体を構成する長尺材と棒状構造体をアルミニウム合金製とすると、雨水や湿気により腐食することがないので、供用後の維持管理費用を大幅に削減することができる。また、押出形材を適宜な長さ・角度で切断するだけで長尺材および棒状構造部材を製造することができるので、大量生産に適しているといえる。さらに、押出形材の寸法精度が木材等と比べて格段に高いので、複数の押出形材を連設した場合であっても、狂いの少ない建物を構築することができる。また、アルミニウム合金製の押出形材が強度の割に軽量であるが故に、現場での取り回しが容易になるという利点もある。 When the long material and the rod-like structure constituting the planar structure are made of an aluminum alloy, they are not corroded by rainwater or moisture, so that the maintenance cost after use can be greatly reduced. In addition, it can be said that it is suitable for mass production because a long material and a rod-like structural member can be produced by simply cutting the extruded shape member at an appropriate length and angle. Furthermore, since the dimensional accuracy of the extruded profile is remarkably higher than that of wood or the like, it is possible to construct a building with few deviations even when a plurality of extruded profiles are arranged in series. Further, since the extruded shape made of an aluminum alloy is light in weight for its strength, there is also an advantage that handling on the site becomes easy.

前記各長尺材は、壁面、屋根面または床面を構成する外殻板の側縁から前記棒状構造体側に立ち上がる継手板を具備しており、前記継手板の前記棒状構造体側の端部である先端部は、内側に折れ曲がっている。前記ブラケットとしては、前記継手板の前記先端部に当接する当接部と、当該当接部の前記面状構造体側の面に突設された挟持部とを有するものを用いる。このようなブラケットを使用した場合には、前記挟持部が隣り合う二つの前記長尺材の前記継手板に挟持されることになる。なお、前記両継手板および前記挟持部を貫通するボルトを利用して前記両長尺材と前記ブラケットとを接合し、前記蓋部および前記当接部を貫通するボルトを利用して前記蓋部材と前記ブラケットとを接合するとよい。 Each elongated member is a wall, from the side edges of the shell plate constituting the roof or floor is provided with a coupling plate that rises to said rod-like structure side, at the end of the rod-shaped structure side of the joint plate A tip is bent inward. As the bracket, the front Symbol abutment portion which abuts with the distal end portion of the joint plate, Ru used having a abutting portion of the planar structure sandwiching portion projecting from the surface of the body side. When such a bracket is used, the sandwiching portion is sandwiched between the joint plates of the two long materials adjacent to each other. In addition, both the long material and the bracket are joined using the bolts penetrating the both joint plates and the clamping part, and the lid member is utilized using the bolt penetrating the lid part and the contact part. And the bracket may be joined.

また、本発明に係る接合構造において、例えば、前記面状構造体の他方の面が外気に接しており、且つ、前記棒状構造体が室内に配置されている場合には、前記蓋部材の前記蓋部と前記ブラケットの前記当接部との間に断熱部材を介設してもよい。 In the joining structure according to the present invention, for example, when the other surface of the planar structure is in contact with outside air and the rod-shaped structure is disposed indoors, the lid member A heat insulating member may be interposed between the lid portion and the contact portion of the bracket.

このようにすると、いわゆるヒートブリッジの発生を防止することができるので、冬期における結露の発生を防止することができる。 In this way, the occurrence of so-called heat bridge can be prevented, so that the occurrence of condensation in winter can be prevented.

また、前記面状構造体が壁体であり、前記棒状構造体が梁材である場合には、前記当接部の前記梁材側の面に突設された載置部を備えるブラケットを使用し、この載置部に前記梁材の端部を載置してもよい。 Further, when the planar structure is a wall body and the rod-shaped structure is a beam material, a bracket having a mounting portion protruding from the beam material side surface of the contact portion is used. And the edge part of the said beam material may be mounted in this mounting part.

このようにブラケットに載置部を設けると、梁材が確実に壁体に支持されることになり、さらに施工時には、この載置部上に梁材を仮置きしておくことも可能となるので、その組立作業も容易になる。 When the mounting portion is thus provided on the bracket, the beam material is surely supported by the wall body, and it is also possible to temporarily place the beam material on the mounting portion at the time of construction. Therefore, the assembly work is also facilitated.

なお、前記蓋部材の前記蓋部と前記ブラケットの前記当接部との間および前記梁材の下面と前記ブラケットの前記載置部との間に断熱部材を介設してもよい。このようにすると、ヒートブリッジの発生を防止することができる。 A heat insulating member may be interposed between the lid portion of the lid member and the contact portion of the bracket and between the lower surface of the beam member and the mounting portion of the bracket . If it does in this way, generation | occurrence | production of a heat bridge can be prevented.

また、壁体から梁材への熱伝達が断熱部材にて遮断されている場合には、鉛直面内に配置される縦ブレースの一端を、縦連結部材を介して前記梁材に接合してもよい。この場合、前記両フランジは、上下に間隔をあけて対向しており、かつ、下側に位置する前記フランジの端部は、前記両ウェブの間に位置する部位に形成された切除部を有し、前記縦連結部材の上半部分は、前記両ウェブの間に挿入されており、前記縦連結部材の下半部分は、前記切除部から下方に突出しており、前記両ウェブおよび前記挿入部を貫通する前記ボルトが、前記縦連結部材の上半部分を貫通しており、当該ボルトを利用して前記梁材と前記縦連結部材とが接合されており、前記縦ブレースの一端が、前記縦連結部材の下半部分に接合されていることが好ましい。また、前記縦連結部材は、前記挿入部を挟む一対の連結板からなることが好ましい。また、水平面内に配置される横ブレースの一端を、横連結部材を介して前記梁材に接合してもよい。この場合、前記横連結部材は、一方の前記ウェブに固定される固定部と、前記固定部に突設された連結部とを有し、前記両ウェブおよび前記挿入部を貫通する前記ボルトが、前記固定部を貫通しており、当該ボルトを利用して前記梁材と前記横連結部材とが接合されていることが好ましい。 Further, when heat transfer from the wall body to the beam member is blocked by the heat insulating member, one end of the vertical brace arranged in the vertical plane is joined to the beam member via the vertical connecting member. also not good. In this case, the flanges are opposed to each other with a gap therebetween, and the end portion of the flange located on the lower side has a cut portion formed in a portion located between the webs. The upper half portion of the vertical connection member is inserted between the webs, and the lower half portion of the vertical connection member protrudes downward from the cut portion. The bolt passing through the upper half of the vertical connecting member, the beam member and the vertical connecting member are joined using the bolt, and one end of the vertical brace is It is preferable to be joined to the lower half portion of the longitudinal connecting member. Moreover, it is preferable that the said longitudinal connection member consists of a pair of connection board which pinches | interposes the said insertion part. Moreover, you may join the end of the horizontal brace arrange | positioned in a horizontal surface to the said beam material via a horizontal connection member . In this case, the horizontal connecting member has a fixing portion fixed to one of the webs, and a connecting portion protruding from the fixing portion, and the bolt penetrating the both webs and the insertion portion, It is preferable that the fixing portion is penetrated and the beam member and the lateral coupling member are joined using the bolt.

このように、壁体からの熱伝達が遮断された状態にある梁材に縦ブレースあるいは横ブレースを接合すると、壁体からの熱が縦ブレースあるいは横ブレースへ伝達するのを阻止することができるので、例えば、冬期における結露の発生を防止することができる。 As described above, when the vertical brace or the horizontal brace is joined to the beam member in which the heat transfer from the wall is cut off, it is possible to prevent the heat from the wall from being transmitted to the vertical brace or the horizontal brace. Therefore, for example, the occurrence of condensation in winter can be prevented.

When the angle formed by the roof surface and the horizontal plane is θ (degrees), the angle θ ′ (degrees) has the following relationship.
sin (θ / 2) = (sin (A / 2)) / (cos (B / 2)) = tan (θ ′ / 2)
Hereinafter, the angle θ (degrees) formed by the roof surface and the horizontal plane is referred to as “roof inclination angle θ (degrees)” or simply “θ (degrees)”.

図３は、建物Ｔ１の側面図（建物Ｔ１を奥行方向に直交する方向から見た図）である。この図に示すように、建物Ｔ１を側面視する（建物Ｔ１を奥行方向に直交する方向から見る）と、壁体１は、その上辺および下辺を斜辺とする等脚台形であることから、その上辺が水平線ｈに対して屋根傾斜角θ（度）で傾斜するとともに、その平行な二辺（短辺１ｔ、長辺１ｕ）が鉛直線ｖに対して角度θ／２（度）だけ背面側に傾斜することになる。また、図１（ｂ）および図２に示すように、壁体１は、その短辺１ｔが床体３の長辺３ｕ側に位置し、長辺１ｕが床体３の短辺３ｔ側に位置するように立設されている。 FIG. 3 is a side view of the building T1 (a view of the building T1 viewed from a direction orthogonal to the depth direction).

It can be said that they are constructed in a row. In the following description, when distinguishing one constituent material from another constituent material adjacent to the front side or another constituent material adjacent to the back side, the reference numeral “′” or “ "" Is attached.

壁構成材１０は、図５に示すように、その上辺１０ｔと下辺１０ｕとを斜辺とする等脚台形を呈している。また、壁構成材１０を側面視すると、上辺１０ｔと壁構成材１０の中心線ｐとがなす角度が９０−θ／２（度）であり、同じく下辺１０ｕと中心線ｐとがなす角度が９０−θ／２（度）である。なお、壁構成材１０は、床構成材３０に垂直な面内であって、床構成材３０の斜辺３０ｔ（図１０参照）を含む面内に立設されるが、下辺１０ｕと中心線ｐとがなす角度が９０−θ／２（度）であることから、壁構成材１０の中心線ｐが前記した面内において垂直線ｖ（床体３が水平であれば鉛直になる）に対してθ／２（度）だけ傾斜し、且つ、上辺１０ｔが水平線ｈに対してθ（度）で傾斜することになる。また、壁構成材１０を側面視すると、壁構成材１０の一対の斜辺（上辺１０ｔ、下辺１０ｕ）がなす角度は、屋根傾斜角θ（度）と等しい。なお、展開図で見れば、壁構成材１０の一対の斜辺（上辺１０ｔ、下辺１０ｕ）がなす角度は、角度θ’（度）（図２参照）と等しい。 As shown in FIG. 5, the wall constituent material 10 has an isosceles trapezoidal shape having the upper side 10 t and the lower side 10 u as hypotenuses.

Further, when the wall constituent material 10 is viewed from the side, an angle formed by a pair of oblique sides (upper side 10t, lower side 10u) of the wall constituent material 10 is equal to the roof inclination angle θ (degrees). In addition, if it sees with a developed view, the angle which a pair of oblique side (upper side 10t, lower side 10u) of the wall structural member 10 makes is equal to angle (theta) '(degree) (refer FIG. 2).

壁体１を構成する複数の壁構成材１０，１０，…は、その断面の寸法・形状が総て同一であるが、図３に示すように、その長さ寸法が正面側から背面側に向かうにしたがって、順次小さくなっている。すなわち、壁構成材１０の平行な二辺は、その長辺が正面側に隣接する他の壁構成材１０’の短辺と同じ長さになっており、また、その短辺が背面側に隣接する他の壁構成材１０”の長辺と同じ長さになっている。なお、一の壁構成材１０の長さ寸法は、展開図で見たときの幅寸法をＤＷとすると、その正面側に隣接する他の壁構成材１０’よりも２ＤＷ×tan（θ’／２）だけ小さくなっている。 The plurality of wall constituent members 10, 10,... Constituting the wall body 1 are all the same in dimensions and shape in cross section, but as shown in FIG. 3, the length dimension is changed from the front side to the back side. It gets smaller as you go. That is, the two parallel sides of the wall constituent material 10 have the same long side as the short side of the other wall constituent material 10 'adjacent to the front side, and the short side on the back side. It is the same length as the long side of the other adjacent wall constituent member 10 ″. The length dimension of one wall constituent member 10 is the width dimension when viewed in the development view as DW. It is smaller by 2DW × tan (θ ′ / 2) than other wall constituent members 10 ′ adjacent to the front side.

また、壁構成材１０は、図６に示すように、その長手方向に沿って互いに平行に配置された第一の継手板たる前側継手板１１および第二の継手板たる後側継手板１２と、この両継手板１１，１２間に配設された等脚台形を呈する外殻板１３とを備えて構成されている。 Moreover, as shown in FIG. 6, the wall constituent material 10 includes a front joint plate 11 as a first joint plate and a rear joint plate 12 as a second joint plate arranged in parallel with each other along the longitudinal direction thereof. The outer shell plate 13 having an isosceles trapezoidal shape and disposed between the joint plates 11 and 12 is provided.

前側継手板１１および後側継手板１２は、図７（ｃ）に示すように、それぞれ外殻板１３に垂直な面に対して角度θ／２（度）だけ傾斜している。また、図７（ｂ）に示すように、両継手板１１，１２には、それぞれ段差が形成されており、一の壁構成材１０の後側継手板１２を他の壁構成材１０”の前側継手板１１に突き合わせたときに、一の壁構成材１０の後側継手板１２の外面１２ａ（以下、「後側接合端面１２ａ」という）と他の壁構成材１０”の前側継手板１１の外面１１ａ（以下、「前側接合端面１１ａ」という）とが隙間をあけて対向する。すなわち、壁構成材１０は、その前後の縁部に互いに平行な前側接合端面１１ａと後側接合端面１２ａとを有しており、この後側接合端面１２ａを隣接する他の壁構成材１０”の前側接合端面１１ａに突き合わせた状態で他の壁構成材１０”と接合される。 The front joint plate 11 and the rear joint plate 12 are inclined by an angle θ / 2 (degrees) with respect to a plane perpendicular to the outer shell plate 13 as shown in FIG.

When faced with the front joint plate 11, the outer surface 12a of the rear joint plate 12 of one wall constituent member 10 (hereinafter referred to as "rear joint end surface 12a") and the front joint plate 11 of the other wall constituent member 10 ". The outer surface 11a (hereinafter referred to as “front-side joining end surface 11a”) is opposed to each other with a gap. That is, the wall constituent material 10 has a front joint end face 11a and a rear joint end face 12a parallel to each other at the front and rear edges thereof, and the other wall constituent material 10 "adjacent to the rear joint end face 12a. It is joined to the other wall constituent material 10 ″ in a state of being in contact with the front joining end face 11a.

なお、図６に示すように、両継手板１１，１２は、その先端部１１ｂ，１２ｂが内側に折り曲げられている。この折り曲げられた先端部１１ｂ，１２ｂは、内装材等を取り付ける際に利用される。また、このようにすると、壁構成材１０の断面性能が向上し、さらに、壁構成材１０を押出形材で形成する場合には、当該押出形材の押出精度が向上するという利点もある。また、壁構成材１０の両継手板１１，１２は、屋根構成材２０の両継手板２１，２２および床構成材３０の両継手板３１，３２と干渉しないように、その長手方向の端部（図６中、符号１１ｃ，１２ｃを付した部位）が切除されている。 In addition, as shown in FIG. 6, both joint plates 11 and 12 have their tip portions 11b and 12b bent inward. The bent tip portions 11b and 12b are used when attaching an interior material or the like. This also has the advantage that the cross-sectional performance of the wall component 10 is improved, and further, when the wall component 10 is formed of an extruded profile, the extrusion accuracy of the extruded profile is improved. Further, both joint plates 11 and 12 of the wall constituent material 10 are end portions in the longitudinal direction so as not to interfere with both joint plates 21 and 22 of the roof constituent material 20 and both joint plates 31 and 32 of the floor constituent material 30. (Parts denoted by reference numerals 11c and 12c in FIG. 6) are excised.

また、図６に示すように、短手方向に隣り合う壁構成材１０，１０の間、より具体的には、一の壁構成材１０の後側継手板１２と他の壁構成材１０の前側継手板１１との間には、平板状の補剛材４１が介設される。 Moreover, as shown in FIG. 6, between the wall constituent materials 10 and 10 adjacent in a transversal direction, more specifically, the rear joint plate 12 of one wall constituent material 10 and the other wall constituent materials 10 A flat stiffener 41 is interposed between the front joint plate 11.

補剛材４１は、図７（ｂ）に示すように、一の壁構成材１０の後側継手板１２（後側接合端面１２ａ）とこれに隣接する他の壁構成材１０”の前側継手板１１（前側接合端面１１ａ）との間に形成された隙間にちょうど嵌り込む厚さに形成されており、一の壁構成材１０の後側継手板１２と他の壁構成材１０”の前側継手板１１とともにリブＲ１を構成する。すなわち、一の壁構成材１０の後側継手板１２とこれに隣接する他の壁構成材１０”の前側継手板１１と補剛材４１とにより、壁構成材１０，１０”の境界面に沿ってリブＲ１が形成されることになる。なお、各壁構成材１０において、その長手方向に沿って形成された両継手板１１，１２は、それぞれ単独でも「リブ」として機能するが、補剛材４１と一体にしてリブＲ１を形成することで、各ユニットＵ１の剛性をより一層向上させることができる。また、このように壁構成材１０とは別部材の補剛材４１を用いれば、壁構成材１０の設置条件が異なる場合であっても、補剛材４１の剛性を変化させるだけで容易に対応することができる。 As shown in FIG. 7 (b), the stiffener 41 is composed of a rear joint plate 12 (rear joint end face 12a) of one wall constituent member 10 and a front joint of another wall constituent member 10 ″ adjacent thereto. It is formed to have a thickness that fits into a gap formed between the plate 11 (front-side joining end surface 11a) and the front side of the rear joint plate 12 of one wall component 10 and the other wall component 10 ″. The rib R1 is configured together with the joint plate 11. That is, the rear joint plate 12 of one wall constituent member 10 and the front joint plate 11 and the stiffener 41 of the other wall constituent member 10 ″ adjacent to the wall joint member 10 on the boundary surface of the wall constituent members 10 and 10 ″. A rib R1 is formed along the line. In each of the wall constituent members 10, both joint plates 11 and 12 formed along the longitudinal direction function as “ribs” alone, but form the rib R 1 integrally with the stiffener 41. Thus, the rigidity of each unit U1 can be further improved. Further, if the stiffener 41 which is a member different from the wall constituent material 10 is used as described above, even if the installation conditions of the wall constituent material 10 are different, it is easy to change the rigidity of the stiffener 41. Can respond.

さらに、図６に示すように、一の壁構成材１０の前側継手板１１と他の壁構成材１０’の後側継手板１２との間であって、壁構成材１０と屋根構成材２０（図４参照）との境界部分には、Ｌ字形状を呈する連結材５１が介設され、同様に、壁構成材１０と床構成材３０（図４参照）との境界部分には、Ｌ字形状を呈する連結材５２が介設される。そして、連結材５１により、壁構成材１０と屋根構成材２０とが剛に接合され、また、連結材５２により壁構成材１０と床構成材３０とが剛に接合されるので、ユニットＵ１の剛性が非常に高いものとなる。 Furthermore, as shown in FIG. 6, between the front joint plate 11 of one wall constituent material 10 and the rear joint plate 12 of the other wall constituent material 10 ′, the wall constituent material 10 and the roof constituent material 20. A connecting member 51 having an L-shape is interposed in a boundary portion between the wall constituent material 10 and the floor constituent material 30 (see FIG. 4). A connecting member 52 having a letter shape is interposed. The wall component 10 and the roof component 20 are rigidly joined by the connecting member 51, and the wall component 10 and the floor component 30 are rigidly joined by the connecting member 52. The rigidity is very high.

屋根構成材２０は、図８に示すように、壁構成材１０の上辺１０ｔ（図５参照）と接する辺２０ｔ，２０ｕを斜辺とする等脚台形を呈している。また、屋根構成材２０を平面視すると、辺２０ｔ（２０ｕ）と中心線ｐとがなす角度は、９０−θ／２（度）である。すなわち、屋根構成材２０の一対の斜辺（辺２０ｔ，２０ｕ）がなす角度は、屋根傾斜角θ（度）と等しい。なお、展開図で見れば、屋根構成材２０の一対の斜辺（辺２０ｔ、２０ｕ）がなす角度は、角度θ’（度）（図２参照）と等しい。 As shown in FIG. 8, the roof constituent material 20 has an isosceles trapezoidal shape with sides 20 t and 20 u contacting the upper side 10 t (see FIG. 5) of the wall constituent material 10 as hypotenuses. Further, when the roof component 20 is viewed in plan, the angle formed by the side 20t (20u) and the center line p is 90-θ / 2 (degrees). That is, the angle formed by the pair of oblique sides (sides 20t, 20u) of the roof component 20 is equal to the roof inclination angle θ (degrees). In addition, if it sees with an expanded view, the angle which a pair of oblique side (side 20t, 20u) of the roof structural member 20 makes is equal to angle (theta) '(degree) (refer FIG. 2).

屋根２を構成する複数の屋根構成材２０，２０，…は、その断面の寸法・形状が総て同一であるが、図１（ｂ）に示すように、その長さ寸法が正面側から背面側に向かうにしたがって、順次小さくなっている。すなわち、屋根構成材２０の平行な二辺は、その短辺が正面側に隣接する他の屋根構成材２０’の長辺と同じ長さになっており、また、その長辺が背面側に隣接する他の屋根構成材２０”の短辺と同じ長さになっている。なお、一の屋根構成材２０の長さ寸法は、展開図で見たときの幅寸法をＤＲとすると、その正面側に隣接する他の屋根構成材２０よりも２ＤＲ×tan（θ’／２）だけ大きくなっている。 The plurality of roof constituent members 20, 20,... Constituting the roof 2 are all the same in cross-sectional dimensions and shapes, but as shown in FIG. It becomes smaller gradually toward the side. That is, the two parallel sides of the roof component 20 have the same short side as the long side of the other roof component 20 ′ adjacent to the front side, and the long side on the back side. It is the same length as the short side of the other adjacent roof constituent material 20 ″. Note that the length dimension of one roof constituent material 20 is DR when the width dimension when viewed in the developed view is DR. It is larger by 2DR × tan (θ ′ / 2) than other roof components 20 adjacent to the front side.

屋根構成材２０は、図９（ａ）に示すように、屋根面となる外殻板２３と、この外殻板２３の短手方向に間隔をあけて配置された第一の継手板たる前側継手板２１および第二の継手板たる後側継手板２２とを備えて構成されている。外殻板２３は、本実施形態では等脚台形を呈している（図８参照）。 As shown in FIG. 9 (a), the roof component 20 is composed of an outer shell plate 23 serving as a roof surface, and a front side serving as a first joint plate disposed at an interval in the short direction of the outer shell plate 23. A joint plate 21 and a rear joint plate 22 as a second joint plate are provided. In the present embodiment, the outer shell plate 23 has an isosceles trapezoid (see FIG. 8).

前側継手板２１および後側継手板２２は、図９（ｃ）に示すように、それぞれ外殻板２３に垂直な面に対して角度θ／２（度）だけ傾斜しており、その離隔距離ｙは、図７（ｃ）に示す壁構成材１０の両継手板１１，１２の離隔距離ｘと等しい。つまり、前側継手板２１および後側継手板２２は、外殻板２３の長手方向に沿って互いに平行に配置されている。また、図９（ｂ）に示すように、両継手板２１，２２には、それぞれ段差が形成されており、一の屋根構成材２０の後側継手板２２を他の屋根構成材２０”の前側継手板２１に突き合わせたときに、一の屋根構成材２０の後側継手板２２の外面２２ａ（以下、「後側接合端面２２ａ」という）と他の壁構成材２０”の前側継手板２１の外面２１ａ（以下、「前側接合端面２１ａ」という）とが隙間をあけて対向する。すなわち、屋根構成材２０は、その前後の縁部に互いに平行な前側接合端面２１ａと後側接合端面２２ａとを有しており、この後側接合端面２２ａを隣接する他の屋根構成材２０”の前側接合端面２１ａに突き合わせた状態で他の屋根構成材２０”と接合される。 The front joint plate 21 and the rear joint plate 22 are inclined by an angle θ / 2 (degrees) with respect to a plane perpendicular to the outer shell plate 23, as shown in FIG. y is equal to the separation distance x of both the joint plates 11 and 12 of the wall constituent material 10 shown in FIG. That is, the front joint plate 21 and the rear joint plate 22 are arranged in parallel to each other along the longitudinal direction of the outer shell plate 23. Further, as shown in FIG. 9B, the joint plates 21 and 22 are respectively provided with steps, and the rear joint plate 22 of one roof component 20 is connected to the other roof component 20 ″. When faced with the front joint plate 21, the outer surface 22a of the rear joint plate 22 of one roof component 20 (hereinafter referred to as "rear joint end surface 22a") and the front joint plate 21 of the other wall component 20 ". The outer surface 21a (hereinafter referred to as “front-side joining end surface 21a”) is opposed to the outer surface 21a. That is, the roof component 20 has a front joint end surface 21a and a rear joint end surface 22a which are parallel to each other at the front and rear edges thereof, and another roof component 20 "adjacent to the rear joint end surface 22a. Are joined to the other roof constituent material 20 "in a state of being in contact with the front joining end face 21a.

なお、図９（ｃ）に示すように、両継手板２１，２２は、その先端部２１ｂ，２２ｂが内側に折り曲げられている。この折り曲げられた先端部２１ｂ，２２ｂは、内装材等を取り付ける際に利用される。また、このようにすると、屋根構成材２０の断面性能が向上し、さらに、屋根構成材２０を押出形材で形成する場合には、当該押出形材の押出精度が向上するという利点もある。また、図６に示す壁構成材１０と同様に、屋根構成材２０の両継手板２１，２２は、その長手方向の端部が切除されている。 In addition, as shown in FIG.9 (c), both the joint plates 21 and 22 have the front-end | tip parts 21b and 22b bent inside. The bent tip portions 21b and 22b are used when attaching an interior material or the like. In addition, in this way, the cross-sectional performance of the roof component 20 is improved, and further, when the roof component 20 is formed of an extruded shape, there is an advantage that the extrusion accuracy of the extruded shape is improved. Similarly to the wall constituent material 10 shown in FIG. 6, both joint plates 21 and 22 of the roof constituent material 20 have their longitudinal ends cut off.

また、図９（ｂ）に示すように、短手方向に隣り合う屋根構成材２０，２０の間、より具体的には一の屋根構成材２０の後側継手板２２と他の屋根構成材２０”の前側継手板２１との間には、平板状の補剛材４２が介設されており、一の屋根構成材２０の後側継手板２２と他の屋根構成材２０”の前側継手板２１とともにリブＲ２を構成する。なお、補剛材４２の構成および機能は、前記した補剛材４１と同様であるので、詳細な説明は省略するが、屋根構成材２０とは別部材の補剛材４２を用いているので、屋根構成材２０の設置条件が異なる場合であっても、補剛材４２の剛性を変化させるだけで容易に対応することができる。すなわち、補剛材４２の断面形状を適宜調節するだけで、屋根構成材２０の断面形状を変化させなくとも、屋根２（図１参照）の剛性を変化させることが可能となる。 Moreover, as shown in FIG.9 (b), between the roof structural materials 20 and 20 adjacent to a transversal direction, more specifically, the back side joint board 22 of one roof structural material 20, and another roof structural material. A flat stiffener 42 is interposed between the front joint plate 21 of 20 ″ and the rear joint plate 22 of one roof component 20 and the front joint of another roof component 20 ″. The rib R2 is configured together with the plate 21. Since the configuration and function of the stiffener 42 are the same as those of the stiffener 41 described above, detailed description is omitted, but the stiffener 42 that is a separate member from the roof constituent 20 is used. Even if the installation conditions of the roof component 20 are different, it can be easily handled by changing the rigidity of the stiffener 42. That is, it is possible to change the rigidity of the roof 2 (see FIG. 1) without changing the cross-sectional shape of the roof constituting material 20 only by appropriately adjusting the cross-sectional shape of the stiffener 42.

さらに、一の屋根構成材２０の後側継手板２２と他の屋根構成材２０”の前側継手板２１との間であって、壁構成材１０と屋根構成材２０（図５参照）との境界部分には、Ｌ字形状を呈する連結材５１（図６参照）が介設される。 Further, between the rear joint plate 22 of one roof component 20 and the front joint plate 21 of the other roof component 20 ″, the wall component 10 and the roof component 20 (see FIG. 5) A connecting member 51 (see FIG. 6) having an L shape is interposed at the boundary portion.

床構成材３０は、図８および図９に示す屋根構成材２０と同一である。すなわち、壁構成材１０の下辺１０ｕ（図５参照）と接する辺を斜辺とする等脚台形を呈しており、その長手方向に沿って互いに平行に配置された前側継手板３１および後側継手板３２（図９参照）と、この両継手板３１，３２間に配設された外殻板３３とを備えて構成されている。また、両継手板３１，３２は、外殻板３３に垂直な面に対して角度θ／２（度）だけ傾斜している（図９（ｃ）参照）。 The floor component 30 is the same as the roof component 20 shown in FIGS. 8 and 9. That is, it has an isosceles trapezoidal shape with the side in contact with the lower side 10u (see FIG. 5) of the wall constituting member 10 as a hypotenuse, and the front joint plate 31 and the rear joint plate arranged parallel to each other along the longitudinal direction thereof. 32 (see FIG. 9) and an outer shell plate 33 disposed between the joint plates 31 and 32. Further, the joint plates 31 and 32 are inclined by an angle θ / 2 (degrees) with respect to a plane perpendicular to the outer shell plate 33 (see FIG. 9C).

また、図１０に示すように、一の床構成材３０の前側継手板３１と他の床構成材３０’の後側継手板３２との間には、平板状の補剛材４３が介設されており、一の床構成材３０の前側継手板３１と他の床構成材３０’の後側継手板３２とともに、リブＲ３を構成する。なお、補剛材４３の構成および機能は、前記した補剛材４１，４２と同様であるので、詳細な説明は省略する。 As shown in FIG. 10, a flat stiffener 43 is interposed between the front joint plate 31 of one floor component 30 and the rear joint plate 32 of the other floor component 30 ′. The rib R3 is configured together with the front joint plate 31 of one floor constituent member 30 and the rear joint plate 32 of the other floor constituent member 30 ′. In addition, since the structure and function of the stiffener 43 are the same as those of the stiffeners 41 and 42 described above, detailed description thereof is omitted.

さらに、図１０に示すように、一の床構成材３０の前側継手板３１と他の床構成材３０’の後側継手板３２との間であって、壁構成材１０と床構成材３０との境界部分には、Ｌ字形状を呈する連結材５２が介設される。 Furthermore, as shown in FIG. 10, between the front joint plate 31 of one floor constituent material 30 and the rear joint plate 32 of another floor constituent material 30 ′, the wall constituent material 10 and the floor constituent material 30. A connecting member 52 having an L shape is interposed at a boundary portion between the two.

壁構成材１０、屋根構成材２０および床構成材３０をそれぞれ前記した規則に従って形成した場合には、これらの断面形状・寸法を同一にすることができる。言い換えれば、一種類の形材から壁構成材１０、屋根構成材２０および床構成材３０を形成することが可能となる。すなわち、図７（ｃ）に示す断面を有する形材を、長手方向と直交する方向に対して角度θ’／２（度）（平面視したときにはθ／２（度））だけ傾斜させた面で切断するだけで、各構成材１０，２０，３０を形成することができるので、非常に経済的である。 When the wall constituent material 10, the roof constituent material 20, and the floor constituent material 30 are formed according to the rules described above, their cross-sectional shapes and dimensions can be made the same. In other words, the wall constituent material 10, the roof constituent material 20, and the floor constituent material 30 can be formed from one type of shape. That is, a surface in which a profile having a cross section shown in FIG. 7C is inclined by an angle θ ′ / 2 (degrees) (θ / 2 (degrees when viewed in plan)) with respect to a direction orthogonal to the longitudinal direction. Since each component 10, 20, and 30 can be formed only by cut | disconnecting by, it is very economical.

また、壁構成材１０、屋根構成材２０および床構成材３０は、アルミニウム合金製の押出形材とするのがよい。このようにすると、白蟻の食害を受けることがなく、さらには、雨水や湿気により腐食することもないので、供用後の維持管理費用を大幅に削減することができる。また、各構成材１０，２０，３０は、押出形材を適宜な長さ・角度で切断するだけで製造することができるので、大量生産に適している。さらに、押出形材の寸法精度が木材等と比べて格段に高いので、複数の押出形材を連設した場合であっても、狂いの少ない建物とすることができる。また、強度の割に軽いアルミニウム合金製の押出形材で各構成材１０，２０，３０を形成するため、現場での取り回しが容易になるという利点もある。 Moreover, the wall constituent material 10, the roof constituent material 20, and the floor constituent material 30 are preferably made of extruded shapes made of an aluminum alloy. If it does in this way, it will not receive the damage of a white ant, and since it will not corrode by rainwater or moisture, the maintenance cost after service can be reduced significantly. Further, each of the constituent members 10, 20, and 30 can be manufactured only by cutting the extruded shape member at an appropriate length and angle, and thus is suitable for mass production. Furthermore, since the dimensional accuracy of the extruded profile is remarkably higher than that of wood or the like, even if a plurality of extruded profiles are connected in series, the building can be made less crazy. In addition, since the constituent members 10, 20, and 30 are formed of extruded shapes made of an aluminum alloy that is light in strength, there is also an advantage that handling on the site becomes easy.

また、壁構成材１０、屋根構成材２０および床構成材３０をそれぞれ前記した規則に従って形成した場合には、壁構成材１０の前側継手板１１と屋根構成材２０の前側継手板２１と床構成材３０の前側継手板３１とが同一平面上に位置することになり、且つ、壁構成材１０の後側継手板１２と屋根構成材２０の後側継手板２２と床構成材３０の後側継手板３２とが同一平面上に位置することになるので、壁構成材１０，１０”間のリブＲ１（図７（ｂ）参照）、屋根構成材２０，２０”間のリブＲ２（図９（ｂ）参照）および床構成材３０，３０”間のリブＲ３（図１０参照）も同一平面上に形成されることになる（以下、リブＲ１，Ｒ２，Ｒ３を総称して「リブＲ」という）。そして、リブＲにより、ユニットＵ１の面内方向の剛性（せん断剛性）が特に向上し、さらに、このようなリブＲが、奥行方向に所定の間隔をあけて複数箇所に形成されることになるので、建物Ｔ２は、非常に高い剛性を有しているといえる。なお、複数のリブＲは、互いに平行である。 Moreover, when the wall component 10, the roof component 20, and the floor component 30 are formed according to the rules described above, the front joint plate 11 of the wall component 10, the front joint plate 21 of the roof component 20, and the floor configuration, respectively. The front joint plate 31 of the material 30 is located on the same plane, and the rear joint plate 12 of the wall constituent material 10, the rear joint plate 22 of the roof constituent material 20, and the rear side of the floor constituent material 30. Since the joint plate 32 is located on the same plane, the rib R1 (see FIG. 7B) between the wall constituent members 10 and 10 ″ and the rib R2 (see FIG. 9) between the roof constituent members 20 and 20 ″. (B)) and the rib R3 (see FIG. 10) between the floor components 30, 30 ″ are also formed on the same plane (hereinafter, the ribs R1, R2, R3 are collectively referred to as “rib R”). Called). The rib R particularly improves the in-plane rigidity (shear rigidity) of the unit U1, and such ribs R are formed at a plurality of locations at predetermined intervals in the depth direction. Therefore, it can be said that the building T2 has very high rigidity. The plurality of ribs R are parallel to each other.

さらに、ユニットＵ１において、壁構成材１０がその上辺１０ｔと下辺１０ｕ（図５参照）とを斜辺とする等脚台形であり、且つ、屋根構成材２０と床構成材３０とが同一であることから、壁構成材１０と屋根構成材２０との接合構造と、壁構成材１０と床構成材３０との接合構造が同一になる。 Furthermore, in the unit U1, the wall constituent material 10 is an isosceles trapezoid whose upper side 10t and lower side 10u (see FIG. 5) are hypotenuses, and the roof constituent material 20 and the floor constituent material 30 are the same. Therefore, the joint structure between the wall constituent member 10 and the roof constituent member 20 and the joint structure between the wall constituent member 10 and the floor constituent member 30 are the same.

（建物の構築方法）
次に、建物Ｔ１の構築方法の一例を、図１０を参照して説明する。
まず、既に枠状に組み立てられたユニットＵ１の床構成材３０の前側継手板３１に、その正面側に隣接するユニットＵ１’を構成する床構成材３０’の後側継手板３２を突き合わせる。 (Building method)
Next, an example of a construction method of the building T1 will be described with reference to FIG.
First, the rear joint plate 32 of the floor constituent member 30 ′ constituting the unit U1 ′ adjacent to the front side joint plate 31 of the floor constituent member 30 of the unit U1 already assembled in a frame shape is abutted.

続いて、ユニットＵ１の床構成材３０の前側接合端面３１ａ（図９（ｂ）参照）とユニットＵ１’の床構成材３０’の後側接合端面３２ａ（図９（ｂ）参照）との間に形成された隙間に平板状の補剛材４３を介設するとともに、壁構成材１０との境界部分に連結材５２を介設し、さらに、これらをボルトＢ１・ナットＮ１で一体にする。 Subsequently, between the front side joining end surface 31a (see FIG. 9B) of the floor constituent material 30 of the unit U1 and the rear side joining end surface 32a (see FIG. 9B) of the floor constituent material 30 ′ of the unit U1 ′. A plate-shaped stiffening material 43 is interposed in the gap formed at, and a connecting material 52 is interposed at the boundary with the wall constituting material 10, and these are integrated with bolts B1 and nuts N1.

次に、ユニットＵ１の壁構成材１０の前側継手板１１に、ユニットＵ１’の壁構成材１０’の後側継手板１２（後側接合端面１２ａ）を突き合わせるとともに、ユニットＵ１の壁構成材１０の前側接合端面１１ａ（図７（ｂ）参照）とユニットＵ１’の壁構成材１０’の後側接合端面１２ａ（図７（ｂ）参照）との間に形成された隙間に平板状の補剛材４１を介設し、さらに、屋根構成材２０（図４参照）との境界部分に連結材５１（図６参照）を介設した上で、これらをボルトＢ１・ナットＮ１で一体にする。 Next, the rear joint plate 12 (rear joint end face 12a) of the wall constituent member 10 ′ of the unit U1 ′ is abutted against the front joint plate 11 of the wall constituent member 10 of the unit U1, and the wall constituent member of the unit U1. 10 in the gap formed between the front joint end surface 11a (see FIG. 7 (b)) and the rear joint end surface 12a (see FIG. 7 (b)) of the wall constituent member 10 ′ of the unit U1 ′. A stiffener 41 is interposed, and a connecting member 51 (see FIG. 6) is interposed at the boundary with the roof component 20 (see FIG. 4), and these are integrated with bolts B1 and nuts N1. To do.

同様に、図示は省略するが、ユニットＵ１の屋根構成材２０の前側継手板２１に、ユニットＵ１’の屋根構成材２０’の後側継手板２２を突き合わせ、その間に補剛材４２を介設した上で、これらをボルト・ナットで一体にする（図９（ａ）（ｂ）参照）。 Similarly, although not shown, the rear joint plate 22 of the roof component 20 ′ of the unit U1 ′ is abutted against the front joint plate 21 of the roof component 20 of the unit U1, and a stiffener 42 is interposed therebetween. Then, these are integrated with bolts and nuts (see FIGS. 9A and 9B).

そして、このような作業を順次繰り返して、所定数のユニットＵ１を奥行方向に隙間なく連設し、その後、図１１（ａ）に示すように、正面側の開口部に壁６１、窓６２、ドア６３等を適宜設けるとともに、図１１（ｂ）に示すように、背面側の開口部に窓６４等を適宜設け、さらに、図１２（ａ）（ｂ）に示すように、壁体１、屋根２および床体３の内面に各種仕上材６５を貼り付けるとともに、間仕切壁６６やロフト６７等を設けると、建物Ｔ１の構築が完了する。なお、建物Ｔ１では、構造材たる各構成材１０，２０，３０が隙間なく並べられているので、各構成材１０，２０，３０が外装材を兼ねている。 Then, by repeating such operations in sequence, a predetermined number of units U1 are continuously arranged in the depth direction without gaps, and thereafter, as shown in FIG. 11A, a wall 61, a window 62, A door 63 and the like are provided as appropriate, and a window 64 and the like are appropriately provided in the opening on the back side as shown in FIG. 11 (b). Further, as shown in FIGS. When various finishing materials 65 are pasted on the inner surfaces of the roof 2 and the floor 3 and the partition walls 66 and the loft 67 are provided, the construction of the building T1 is completed. In the building T1, the structural members 10, 20, and 30 that are structural members are arranged without gaps, so that the structural members 10, 20, and 30 also serve as exterior materials.

なお、建物Ｔ１の間取り、窓等の形状・配置等は、適宜変更しても差し支えないことは言うまでもないが、例えば、天井高の大きい正面側にロフト６７を設けることで、正面側に向かうに従って天井高さが漸増する建物Ｔ１の内部空間を有効に利用することが可能となり、さらに、天井高の大きい正面側の開口部の上部に窓６２を設けることで、効率よく太陽光を取り入れることが可能となる。さらに、壁体１，屋根２および床体３だけで強固な構造体となるので、必ずしも建物内部に壁を配置する必要がなく、その結果、間取りの自由度が非常に高いものとなる。 In addition, it goes without saying that the floor plan of the building T1, the shape and arrangement of the windows, etc. can be changed as appropriate. For example, by providing a loft 67 on the front side with a large ceiling height, It is possible to effectively use the internal space of the building T1 where the ceiling height gradually increases. Furthermore, by providing the window 62 at the upper part of the opening on the front side where the ceiling height is large, it is possible to efficiently incorporate sunlight. It becomes possible. Furthermore, since only the wall body 1, the roof 2 and the floor body 3 form a strong structural body, it is not always necessary to dispose a wall inside the building, and as a result, the degree of freedom in floor plan becomes very high.

このように、所定の規則に従って形成された複数の壁構成材１０、屋根構成材２０および床構成材３０を隙間なく連設するだけで天井高さや横幅が漸増・漸減する斬新なデザインの建物Ｔ１を容易に構築することができる。しかも、壁構成材１０と屋根構成材２０との接合構造と、壁構成材１０と床構成材３０との接合構造が同一になるので、組立作業を迅速に行うことができる。さらに、壁構成材１０、屋根構成材２０および床構成材３０を一種類の押出形材から形成することができるので、非常に経済的である。 In this way, the building T1 has a novel design in which the ceiling height and width are gradually increased and decreased by simply connecting a plurality of wall components 10, roof components 20, and floor components 30 formed according to a predetermined rule without any gaps. Can be easily constructed. Moreover, since the joint structure between the wall constituent material 10 and the roof constituent material 20 and the joint structure between the wall constituent material 10 and the floor constituent material 30 are the same, assembly work can be performed quickly. Furthermore, since the wall constituent material 10, the roof constituent material 20, and the floor constituent material 30 can be formed from one type of extruded shape material, it is very economical.

なお、建物Ｔ１の構築手順は、前記したものに限定されることはなく、適宜変更しても差し支えない。例えば、複数の床構成材３０を奥行方向に連設して床体３を構成し、次いで、複数の壁構成材１０を奥行方向に連設して構成した壁体１を床体１の斜辺に沿って立設し、その後、複数の屋根構成材２０を奥行方向に連設して構成した屋根２を壁体１，１間に覆設する、という手順でもよい。 Note that the construction procedure of the building T1 is not limited to the one described above, and may be changed as appropriate. For example, the floor body 3 is configured by connecting a plurality of floor constituent materials 30 in the depth direction, and then the wall body 1 configured by connecting the plurality of wall constituent materials 10 in the depth direction is the hypotenuse of the floor body 1. Then, a procedure may be used in which the roof 2 configured by connecting a plurality of roof components 20 in the depth direction is covered between the wall bodies 1 and 1.

すなわち、複数の床構成材３０を奥行方向に連設して床体３を構成するとともに、各床構成材３０の両端部において隣接する他の床構成材３０’との間にＬ字形の連結材５２（図６参照）を介設しておき、次いで、複数の壁構成材１０を奥行方向に連設して壁体１を構成したうえで、隣接する壁構成材１０，１０’間に床体３に配設された連結材５２の上方へ立ち上がる部分を挿入して壁体１を床体３の斜辺に沿って立設し、その後、複数の屋根構成材２０を奥行方向に連設して屋根２を構成するとともに、各屋根構成材２０の両端部において隣接する他の屋根構成材２０’との間にＬ字形の連結材５１（図６参照）を介設したうえで、この連結材５１の下方へ垂れ下がる部分を壁体１の上端部の隣接する壁構成材１０，１０間に挿入して屋根２を壁体１，１間に覆設する、という手順でもよい。 That is, a plurality of floor components 30 are connected in the depth direction to form the floor body 3, and an L-shaped connection is made between the other floor components 30 ′ adjacent at both ends of each floor component 30. A material 52 (see FIG. 6) is interposed, and then a plurality of wall constituent materials 10 are connected in the depth direction to form the wall body 1 and then between adjacent wall constituent materials 10, 10 ′. A portion that rises upward from the connecting member 52 disposed on the floor 3 is inserted to erect the wall 1 along the oblique side of the floor 3, and then a plurality of roof components 20 are continuously provided in the depth direction. Then, the roof 2 is configured, and an L-shaped connecting member 51 (see FIG. 6) is interposed between the roof constituent members 20 ′ adjacent to each other at both ends of each roof constituent member 20. A portion of the connecting member 51 that hangs downward is inserted between adjacent wall constituent members 10 and 10 at the upper end of the wall 1.
