- the work of the fourth step may be performed in the second step or may be performed in the third step. Specifically, one or a plurality of frame members 50 are fitted between the two vertical members 10, and the frame members 50 are fixed to the vertical members 10 with screws.
- the building method of building 1 may include the fifth step.
- the floor portion 60 having the framework structure is reinforced by the reinforcing member 63.
- the work of the fifth step may be performed in the second step or may be performed in the third step.
- the support fitting 71 is attached to each of the two second floor frame members 62 of the floor portion 60.
- the two support fittings 71 are arranged so as to face each other.
- the reinforcing member 63 is arranged on the space between the two support metal fittings 71, and the end portion of the reinforcing member 63 is inserted into the support metal fitting 71 while lowering the reinforcing member 63. In this way, the reinforcing member 63 is arranged between the two second floor frame members 62.
- the skeleton of the building body 3 and the skeleton of the roof 4 are constructed by the frame.
- the lower part of the building body 3 is fixed to the foundation 2.
- a roof 4 is provided on the upper part of the building body 3. Due to such a structure, when the building body 3 shakes, the deformation of the upper part of the building body 3 may be larger than the deformation of the lower part of the building body 3.
- a reinforcing member also referred to as "flaming” is provided at the corners of the intersecting first horizontal member 11 and the second horizontal member 12 in the upper part of the building body 3. Called
- a reinforcing member (also referred to as “bracing”) that diagonally intersects the two vertical members 10 may be provided between the two vertical members 10 that support the roof 4. Providing such a reinforcing member requires time and effort, and is a factor that prolongs the construction period.
- the roof 4 has a truss structure. Therefore, since the upper part of the building main body 3 is fixed by the roof 4 of the truss structure, the deformation of the upper part of the building main body 3 is suppressed against the shaking. By this amount, the number of reinforcing members can be reduced in the building body 3. In this way, providing such a reinforcing member in the building main body 3 can reduce labor.
- the building 1 includes a foundation 2, a building main body 3 having a framework structure, and a roof 4 having a truss structure. According to this configuration, by attaching the roof 4 having a truss structure to the building body 3 having a framework structure, the upper part of the building body 3 is less likely to be distorted due to the shaking of the ground, and the building 1 as a whole is not easily distorted. Distortion is suppressed. Therefore, the number of reinforcing members provided in the building body 3 can be reduced.
- the building main body 3 includes a plurality of vertical members 10, a plurality of first horizontal members 11, and a second horizontal member 12 provided so as to extend over the plurality of first horizontal members 11.

- the roof frame 80 is fixed to the first horizontal member 11 or the second horizontal member 12 by metal fittings.
- the roof frame 80 connects the two structures including the first horizontal member 11 to each other.
- the roof frame 80 connects the two structures including the second horizontal member 12 to each other.
- one or a plurality of frame members 50 are provided between the two vertical members 10 out of the plurality of vertical members 10. According to this configuration, the wall composed of the plurality of vertical members 10 can be reinforced.
- the frame member 50 is preferably composed of a plurality of standard lumbers 51 having a smaller cross-sectional area than the vertical lumber 10, the first lumber 11 and the second lumber 12. According to this configuration, the cost of the frame member 50 can be reduced.
- the vertical member 10 may be fixed to the foundation 2 by the foundation metal fitting 20.
- the vertical member 10 has a slit 10c.

Abstract
Description
この構成によれば、軸組構造の建屋本体にトラス構造を有する屋根が取り付けられることによって、地面の揺れに対して、建屋本体の上部が歪み難くなり、建築物の全体としての歪が抑制される。このため、建屋本体に設けられる補強部材を少なくできる。
第1結合金具30は、ほぞ突起部31と、ほぞ突起部31に設けられるプレート部32とを備える。ほぞ突起部31は、第1横架材11に設けられるほぞ孔11dに嵌合するように構成される。プレート部32は、垂直材10に設けられるスリット10cに入るように構成される。ほぞ突起部31は、ドリフトピン24によって第1横架材11に固定される。プレート部32は、ドリフトピン24によって垂直材10に固定される。
第2結合金具36は、垂直材10または第1横架材11に固定される固定部37と、固定部37から延びるプレート部38とを備える。固定部37は、ボルトによって垂直材10の側面10bまたは第1横架材11の側面11bに固定される。プレート部38は、第2横架材12に設けられるスリット12bに入るように構成される。プレート部38は、ドリフトピン24によって第2横架材12に固定される。
枠部材50は、軸組構造を有する壁を補強する。壁は、2個の垂直材10と、2個の垂直材10に亘る第1横架材11または第2横架材12とを備える。1または複数の枠部材50は、複数の垂直材10のうちの2個の垂直材10の間に設けられる。好ましくは、枠部材50の厚幅は、壁構造の厚幅と等しい。
上階は、下階の1つ上の階を示す。例えば、床部60は、1階と2階との間に設けられる。他の例では、2階と3階との間に設けられる。さらに別の例では、地下1階と地上階との間に床部60が設けられる。本実施形態では、建築物1は、2階建てである。建築物1は、1階と2階との間に設けられる床部60を備える。
屋根架材81は、2個の第1横架材11または2個の第2横架材12に架けられる。垂木82は、屋根架材81に結合される。本実施形態では、所定角度の角部が形成されるように、2個の垂木82の第1端部が互いに結合される。2個の垂木82の第2端部は互いに離される。屋根架材81の第1端部は、2個の垂木82の一方の垂木82の第2端部付近に結合され、屋根架材81の第2端部は、2個の垂木82の他方の垂木82の第2端部付近に結合される。屋根架材81と2個の垂木82とによって屋根フレーム80の枠が構成される。補強部材83は、屋根フレーム80の枠内にトラス構造が構成されるように、屋根フレーム80の枠に取り付けられる。
建築物1の建築方法は、第1工程~第3工程を含む。第1工程では、基礎2を形成する。第2工程では、基礎2に軸組構造の建屋本体3を作る。
従来の軸組構法によれば、建屋本体3の骨格および屋根4の骨格を軸組によって構築する。建屋本体3の下部は、基礎2に固定されている。建屋本体3の上部には屋根4が設けられている。このような構造のため、建屋本体3が揺れる場合、建屋本体3の下部の変形に比べて、建屋本体3の上部の変形が大きくなる場合がある。揺れに対して建屋本体3の上部の変形を抑制するため、建屋本体3の上部において、交差する第1横架材11と第2横架材12との角部に補強部材(「火打ち」とも呼ばれる)が設けられる。または、屋根4を支える2個の垂直材10の間に、2個の垂直材10に斜めに交差する補強部材(「筋交い」とも呼ばれる)が設けられる場合もある。このような補強部材を設けることは手間を要し、工期を長くさせる要因ともなる。
(1)建築物1は、基礎2と、軸組構造を有する建屋本体3と、トラス構造を有する屋根4とを備える。この構成によれば、軸組構造の建屋本体3にトラス構造を有する屋根4が取り付けられることによって、地面の揺れに対して、建屋本体3の上部が歪み難くなり、建築物1の全体としての歪が抑制される。このため、建屋本体3に設けられる補強部材を少なくできる。
上記実施形態は、建築物および建築物の建築方法が取り得る形態の例示であり、その形態を制限することを意図していない。建築物1は実施形態に例示された形態とは異なる形態を取り得る。その一例は、実施形態の構成の一部を置換、変更、もしくは、省略した形態、または、実施形態に新たな構成を付加した形態である。以下に実施形態の変形例の一例を示す。
・屋根フレーム80は、第1結合金具30または第2結合金具36に準じた金具によって、屋根横架材15に結合されてもよい。
