Description

【０００１】
【発明の属する技術分野】
本発明は、建物の柱構造及びユニット建物並びに建物ユニットの製造方法に関する。
【０００２】
【従来の技術】
ユニット建物として、特許2856646に記載の如く、１階建物ユニット１の上に２階建物ユニット２を搭載し、２階建物ユニット２の上に３階建物ユニット３を搭載してなるものがある（図６）。このユニット建物では、下階建物ユニットの耐力を上階建物ユニットの耐力より大きくする必要があり、１階建物ユニット１や２階建物ユニット２にサブラーメン（又は補強柱）４、５を設けている。
【０００３】
【発明が解決しようとする課題】
従来技術では、１階建物ユニット１や２階建物ユニット２にサブラーメン４、５を設けるものであるため、１階建物ユニット１や２階建物ユニット２の屋内の間取りの制約となり、広い空間や広い間口が取り難い。
【０００４】
尚、下階建物ユニットの耐力を確保するために、下階建物ユニットの柱の板厚を大きくすることも考えられる。しかしながら、３階建て等の高層のユニット建物で、１階建物ユニット１や２階建物ユニット２のサブラーメン４、５を取り除くには、１階建物ユニット１や２階建物ユニット２の柱の板厚アップだけでは対応できない。また、板厚が例えば9mmを越える鋼製角柱では、加工コストが飛躍的に高くなり、採用し難い。
【０００５】
本発明の課題は、下階の屋内の間取りを制約せずに、下階の耐力を簡易に確保することにある。
【０００６】
本発明の他の課題は、下階建物ユニットの屋内の間取りを制約せずに、下階建物ユニットの耐力を簡易に確保することにある。
【０００７】
本発明の他の課題は、複数の建物ユニットを作り分けるに際し、部品の品種数を少なくし、生産管理上の負担を少なくすることにある。

【００２４】

【００２６】
図１の３階建てユニット建物１０は、基礎１１の上に、３階建ての高層部２０と、２階建ての低層部６０とを有し、高層部２０と低層部６０を以下の如くに構築している。
【００２７】
（高層部２０）
高層部２０は、基礎１１の上に１階建物ユニット２１を、１階建物ユニット２１の上に２階建物ユニット２２を、２階建物ユニット２２の上に３階建物ユニット２３を搭載している。

【００３２】
また、１階建物ユニット２１の柱２１Ａの断面の外郭寸法を例えば120mm×120mm、柱２１Ａの板厚を例えば9.0mmとし、２階建物ユニット２２の柱２２Ａの断面の外郭寸法を例えば120mm×120mm、柱２２Ａの板厚を例えば6.0mmとし、３階建物ユニット２３の柱２３Ａの断面の外郭寸法を例えば100mm×100mm、柱２３Ａの板厚を例えば4.5mmとし、１階建物ユニット２１、２階建物ユニット２２にはサブラーメンや補強柱を設けていない。即ち、１階建物ユニット２１、２階建物ユニット２２の柱２１Ａ、２２Ａ（下階建物ユニットの柱）の断面の外郭寸法（120mm）を、３階建物ユニット２３の柱２３Ａ（上階建物ユニットの柱）の断面の外郭寸法（100mm）より大きく設定している。また、１階建物ユニット２１と２階建物ユニット２２の間では、１階建物ユニット２１の柱２１Ａ（下階建物ユニットの柱）の板厚（9.0mm）を２階建物ユニット２２の柱２２Ａ（上階建物ユニットの柱）の板厚（6.0mm）より大きく設定し、２階建物ユニット２２と３階建物ユニット２３の間では、２階建物ユニット２２の柱２２Ａ（下階建物ユニット）の板厚（6.0mm）を３階建物ユニット２３の柱２３Ａ（上階建物ユニットの柱）の板厚（4.5mm）より大きく設定している。
【００３３】
また、基礎１１と１階建物ユニット２１の接合部では、図２に示す如く、基礎１１に設けたアンカーボルト１２に、１階建物ユニット２１の柱２１Ａと床梁２１Ｂのジョイントプレート３１を締結している。
【００３４】
また、１階建物ユニット２１と２階建物ユニット２２の接合部では、図３に示す如く、１階建物ユニット２１の柱２１Ａの頭部に設けたフタプレート４１に取着したガイドピン４１Ａを、２階建物ユニット２２の柱２２Ａの脚部に設けたフタプレート４２に形成したガイド孔４２Ａに嵌合して両建物ユニット２１、２２を位置合せし、１階建物ユニット２１の柱２１Ａと天井梁２１Ｃのジョイントプレート４３と、２階建物ユニット２２の柱２２Ａと床梁２２Ｂのジョイントプレート４４をボルト４５で締結している。
【００３５】
また、２階建物ユニット２２と３階建物ユニット２３の接合部では、図４に示す如く、２階建物ユニット２２の柱２２Ａの頭部に設けたフタプレート５１に取着したガイドピン５１Ａを、３階建物ユニット２３の柱２３Ａの脚部に設けたフタプレート５２に形成したガイド孔５２Ａに嵌合して両建物ユニット２２、２３を位置合せし、２階建物ユニット２２の柱２２Ａと天井梁２２Ｃのジョイントプレート５３と、３階建物ユニット２３の柱２３Ａと床梁２３Ｂのジョイントプレート５４をボルト５５で締結している。
【００３６】
このとき、１階建物ユニット２１と２階建物ユニット２２の位置合わせするガイドピン４１Ａの位置を柱２１Ａ、２２Ａの外側コーナーに対し妻方向距離Ｘ＝50mm、桁方向距離Ｙ＝50mmとし、２階建物ユニット２２と３階建物ユニット２３を位置合せするガイドピン５１Ａの位置を柱２２Ａ、２３Ａの外側コーナーに対し妻方向距離Ｘ＝50mm、桁方向距離Ｙ＝50mmとしている。即ち、ガイドピン４１Ａ、５１Ａの位置を３階建物ユニット２３（上階建物ユニット）の柱２３Ａ（外郭寸法100mm）の軸芯に設定している。
（低層部６０）
【００３７】
低層部６０は、基礎１１の上に１階建物ユニット６１を、１階建物ユニット６１の上に２階建物ユニット６２を搭載している。
【００３８】
１階建物ユニット６１は、４本の角鋼管製柱６１Ａの下端部と上端部のそれぞれに、４本の形鋼製床梁６１Ｂと４本の形鋼製天井梁６１Ｃのそれぞれを接合した骨組構造体である。
【００３９】
２階建物ユニット６２は、４本の角鋼管製柱６２Ａの下端部と上端部のそれぞれに、４本の形鋼製床梁６２Ｂと４本の形鋼製天井梁６２Ｃのそれぞれを接合した骨組構造体である。
【００４０】
このとき、１階建物ユニット６１と２階建物ユニット６２の平面視での外寸を等しくし、１階建物ユニット６１の柱６１Ａの屋外側の側面と、２階建物ユニット６２の柱６２Ａの屋外側の側面を平面視で合致させている。
【００４１】
また、１階建物ユニット６１と相隣る高層部２０の１階建物ユニット２１の側面視での外寸を等しくし、１階建物ユニット６１の柱６１Ａの屋外側の側面と、１階建物ユニット２１の柱２１Ａの屋外側の側面を側面視で合致させている。
【００４２】
また、２階建物ユニット６２と相隣る低層部２０の２階建物ユニット２２の側面視での外寸を等しくし、２階建物ユニット６２の柱６２Ａの屋外側の側面と、２階建物ユニット２２の柱２２Ａの屋外側の側面を側面視で合致させている。
【００４３】
また、１階建物ユニット６１の柱６１Ａの断面の外郭寸法を例えば100mm×100mm、柱６１Ａの板厚を例えば6.0mmとし、２階建物ユニット６２の柱６２Ａの断面の外郭寸法を例えば100mm×100mm、柱６２Ａの板厚を例えば4.5mmとしている。即ち、同一階で隣接する１階建物ユニット２１の柱２１Ａの外郭寸法（120mm）と１階建物ユニット６１の柱６１Ａの外郭寸法（100mm）を同一にしていないし、同じく同一階で隣接する２階建物ユニット２２の柱２２Ａの外郭寸法（120mm）と２階建物ユニット６２の柱６２Ａの外郭寸法（100mm）を同一にしていない。
【００４４】
従って、ユニット建物１０にあっては、高層部２０の柱構造を前述の如くにしたから、以下の作用がある。
【００４５】
▲１▼ユニット建物１０において、下階建物ユニット２１、２２の柱２１Ａ、２２Ａの断面の外郭寸法を大きく設定したから、下階建物ユニット２１、２２の柱２１Ａ、２２Ａの断面性能を向上し、下階建物ユニット２１、２２の柱２１Ａ、２２Ａの耐力を向上できる。柱の板厚アップだけで断面性能を向上しようとする場合に比して、板厚を薄く、加工コストを低く抑えることができ、下階建物ユニット２１、２２の柱２１Ａ、２２Ａの耐力を簡易に確保できる。従って、下階建物ユニット２１、２２にサブラーメンや補強柱等を設けて補強する必要がなく、下階建物ユニット２１、２２の屋内の間取りを制約せず、広い空間や広い開口を確保しながら、下階建物ユニット２１、２２の耐力を簡易に確保できる。また、上階建物ユニット２３から下階建物ユニット２１、２２の外側にバルコニー等を張り出すオーバーハング工法の拡充を図ることができる。
【００４６】
▲２▼下階建物ユニット２１、２２と上階建物ユニット２３の外寸が変わらないので、それらのモジュールを統一化でき、それらの部品や納まりの共通化を図ることができ、それらの生産性を向上できるし、輸送上の不都合を招くこともない。
【００４７】
▲３▼上述▲１▼において、更に、下階建物ユニット２１、２２の柱２１Ａ、２２Ａの板厚を上階建物ユニット２３の柱２３Ａの板厚より大きく設定することにより、下階建物ユニット２１、２２の柱２１Ａ、２２Ａの耐力をより向上できる。
【００４８】
▲４▼下階建物ユニット２１、２２の柱２１Ａ、２２Ａの屋外側の側面と上階建物ユニット２３の柱２３Ａの屋外側の側面を正面視で合致させることにより、断面の外郭寸法が小さい上階建物ユニット２３の柱２３Ａをより屋外側に配置するものとなり、上階建物ユニット２３の屋内空間をより広くとれる。
【００４９】
▲５▼断面の外郭寸法が小さい上階建物ユニット２３の柱２３Ａの軸芯に上下階の位置合せのためのガイドピン４１Ａ、５１Ａを設定した。従って、この上階建物ユニット２３と同一仕様の建物ユニットをユニット建物１０内の低層部の上下階に適用しようとするとき、これら上下階の建物ユニット６１、６２の柱６１Ａ、６２Ａの軸芯に位置するガイドピンを用いてそれら上下階の建物ユニット６２、６２を安定的に位置合せできる。即ち、同一仕様の建物ユニット２３、６１、６２をユニット建物１０の積層の安定を確保しながら、高層部の上階建物ユニット２３と低層部の建物ユニット６１、６２の両方に併用できる標準建物ユニットとし、建物ユニットの共通化、柱の端部に取着されてガイドピン又はガイド孔を備えるフタプレート等の部品の共通化による部品点数の削減を図ることができる。
【００５０】
図１の３階建ユニット建物１０において高層部２０を構成する１階建物ユニット２１及び２階建物ユニット２２と、３階建物ユニット２３とでは、１階建物ユニット２１及び２階建物ユニット２２の柱２１Ａ、２２Ａの断面の外郭寸法を例えば前述の如く120mm×120mmとし、３階建物ユニット２３の柱２３Ａの断面の外郭寸法を例えば前述の如く100mm×100mmとしている。このとき、１階建物ユニット２１及び２階建物ユニット２２と３階建物ユニット２３とはそれらの平面視での外寸を前述の如く等しくしているから、１階建物ユニット２１において相対する柱２１Ａ、２１Ａの間隔（２階建物ユニット２２において相対する柱２２Ａ、２２Ａの間隔も同じ）は、３階建物ユニット２３において相対する柱２３Ａ、２３Ａの間隔より片側20mm短くなる。このため、１階建物ユニット２１において相対する柱２１Ａ、２１Ａの間隔（２階建物ユニット２２において相対する柱２２Ａ、２２Ａの間隔も同じ）と３階建物ユニット２３において相対する柱２３Ａ、２３Ａの間隔の上記相違に対応すべく、１階建物ユニット２１の床梁２１Ｂ、天井梁２１Ｃの長さを３階建物ユニット２３の床梁２３Ｂ、天井梁２３Ｃの長さより全長で40mm短くすることが考えられるが、この場合には後述する理由により、建物ユニット２１〜２３を構成する梁（床梁２１Ｂ〜２３Ｂ、天井梁２１Ｃ〜２３Ｃ）の品種数が極めて多数になる。そこで、建物ユニット２１〜２３を構成する部品の品種数を少なくするため、建物ユニット２１〜２３の柱と梁の接合仕口を図５、図６に示す如くに変形し、建物ユニット２１〜２３を以下の如くに作り分けるものとした。
【００５１】
１階建物ユニット２１を製造するに際し、前述の如く、１階建物ユニット２１において相対する柱２１Ａのそれぞれにジョイントプレート（接続具）３１、４３を接合し、両ジョイントプレート３１、３１に床梁２１Ｂを架け渡すように接合し、両ジョイントプレート４３、４３に天井梁２１Ｃを架け渡すように接合する。ジョイントプレート３１、４３は溝形状に曲げ加工されて柱２１Ａの側面に突き合せ溶接され、各ジョイントプレート３１、４３の内側に床梁２１Ｂ、天井梁２１Ｃの端部が嵌合されて突き合せ溶接される。このとき、ジョイントプレート３１、４３の長さは、例えば180mmとされる（図５（Ａ））。
【００５２】
２階建物ユニット２２を製造するに際し、前述の如く、２階建物ユニット２２において相対する柱２２Ａのそれぞれにジョイントプレート（接続具）４４、５３を接合し、両ジョイントプレート４４、４４に床梁２２Ｂを架け渡すように接合し、両ジョイントプレート５３、５３に天井梁２２Ｃを架け渡すように接合する。ジョイントプレート４４、５３は溝形状に曲げ加工されて柱２２Ａの側面に突き合せ溶接され、各ジョイントプレート４４、５３の内側に床梁２２Ｂ、天井梁２２Ｃの端部が嵌合されて突き合せ溶接される。このとき、ジョイントプレート３１、４３の長さは、例えば180mmとされる（図５（Ａ）と同じ）。
【００５３】
３階建物ユニット２３を製造するに際し、前述の如く、３階建物ユニット２３において相対する柱２３Ａのそれぞれにジョイントプレート（接続具）５４、５６（５６は不図示）を接合し、両ジョイントプレート５４、５４に床梁２３Ｂを架け渡すように接合し、両ジョイントプレート５６、５６に天井梁２３Ｃを架け渡すように接合する。ジョイントプレート５４、５６は溝形状に曲げ加工されて柱２３Ａの側面に突き合せ溶接され、各ジョイントプレート５４、５６の内側に床梁２３Ｂ、天井梁２３Ｃの端部が嵌合されて突き合せ溶接される。このとき、ジョイントプレート５４、５６の長さは、例えば200mmとされる（図５（Ｂ））。
【００５４】
そして、本実施形態では、各建物ユニット２１〜２３において、それらの床梁２１Ｂ〜２３Ｂ、天井梁２１Ｃ〜２３Ｃの長さを互いに同一にした。
【００５５】
このとき、１階建物ユニット２１のジョイントプレート３１、４３の長さ、２階建物ユニット２２のジョイントプレート４４、５３の長さは180mm、３階建物ユニット２３のジョイントプレート５４、５６の長さは200mmとし、１階建物ユニット２１において相対する柱２１Ａ、２１Ａの間隔（２階建物ユニット２２において相対する柱２２Ａ、２２Ａの間隔も同じ）が、３階建物ユニット２３において相対する柱２３Ａ、２３Ａの間隔より片側20mm短くなる分だけ、１階建物ユニット２１と２階建物ユニット２２のジョイントプレート３１、４３、４４、５３の長さを３階建物ユニット２３のジョイントプレート５４、５６の長さより短くした。これにより、１階建物ユニット２１の床梁２１Ｂ、天井梁２１Ｃがジョイントプレート３１、４３に嵌合する長さ（２階建物ユニット２２の床梁２２Ｂ、天井梁２２Ｃがジョイントプレート４４、５３に嵌合する長さも同じ）と３階建物ユニット２３の床梁２３Ｂ、天井梁２３Ｃがジョイントプレート５４、５６に嵌合する長さをともに170mmで同一にした。
【００５６】
従って、本実施形態によれば以下の作用がある。
▲１▼下階建物ユニット２１、２２と上階建物ユニット２３において、図６に示す如く、両者の柱２１Ａ、２２Ａと柱２３Ａの断面の外郭寸法を異にするとき、両者の梁（床梁２１Ｂ〜２３Ｂ、天井梁２１Ｃ〜２３Ｃ）の長さを同一にし、両者のそれぞれにおける柱２１Ａ〜２３Ａと梁（２１Ｂ〜２３Ｂ、２１Ｃ〜２３Ｃ）の端部との間隔の変化をそれらのジョイントプレート（３１、４３、４４、５３、５４、５６）に対する梁（床梁２１Ｂ〜２３Ｂ、天井梁２１Ｃ〜２３Ｃ）の接合位置の設定により吸収する。これにより、両者における柱２１Ａ〜２３Ａの断面の外郭寸法の相違にもかかわらず、両者の梁（床梁２１Ｂ〜２３Ｂ、天井梁２１Ｃ〜２３Ｃ）の長さを同一にできるから、梁の長さを異にするものに比して、両者を構成する部品の品種数を少なくし、生産管理上の負担を少なくできる。
【００５７】

(Lower part 60)
[0037]
The low-rise unit 60 has a first-floor building unit 61 mounted on the foundation 11 and a second-floor building unit 62 mounted on the first-floor building unit 61.
[0038]
The first-floor building unit 61 is a framework in which four shaped steel floor beams 61B and four shaped steel ceiling beams 61C are joined to the lower end and the upper end of four square steel pipe columns 61A, respectively. It is a structure.
[0039]
The second-floor building unit 62 is a framework in which four shaped steel floor beams 62B and four shaped steel ceiling beams 62C are joined to the lower end and the upper end of four square steel pipe columns 62A, respectively. It is a structure.
[0040]
At this time, the first floor building unit 61 and the second floor building unit 62 have the same external dimensions in plan view, the side surface of the pillar 61A of the first floor building unit 61 on the outdoor side, and the column 62A of the second floor building unit 62. The outer side faces are matched in plan view.
[0041]
Further, the first floor building unit 61 and the first floor building unit 21 of the first floor building unit 61 adjacent to the first floor building unit 61 have the same external dimensions in side view, and the first floor building unit 61 has a column 61A outdoor side surface and the first floor building unit 61. The side surfaces of the 21 pillars 21A on the outdoor side are matched in side view.
[0042]
Moreover, the outside dimension in the side view of the second-floor building unit 22 of the lower-rise building 20 adjacent to the second-floor building unit 62 is made equal, and the side surface on the outdoor side of the column 62A of the second-floor building unit 62 and the second-floor building unit The side surfaces of the 22 pillars 22A on the outdoor side are matched in side view.

The outer dimension (120 mm) of the pillar 22A of the building unit 22 and the outer dimension (100 mm) of the pillar 62A of the second-floor building unit 62 are not the same.
[0044]
Therefore, in the unit building 10, since the column structure of the high-rise part 20 is made as described above, the following effects are obtained.
[0045]
(1) In the unit building 10, since the outer dimensions of the cross sections of the pillars 21A, 22A of the lower floor building units 21, 22 are set large, the cross sectional performance of the pillars 21A, 22A of the lower floor building units 21, 22 is improved. The proof stress of the pillars 21A and 22A of the lower floor building units 21 and 22 can be improved. Compared with the case where the cross-sectional performance is improved only by increasing the thickness of the column, the plate thickness can be reduced and the processing cost can be reduced, and the strength of the columns 21A and 22A of the lower floor building units 21 and 22 can be simplified. Can be secured. Therefore, it is not necessary to reinforce the lower-floor building units 21 and 22 by providing sub-ramens, reinforcing columns, etc., and the indoor floor plan of the lower-floor building units 21 and 22 is not restricted, and a wide space and a wide opening are secured. The yield strength of the lower floor building units 21 and 22 can be easily secured. In addition, it is possible to enhance the overhang method for projecting a balcony or the like from the upper building unit 23 to the outside of the lower building units 21 and 22.
[0046]
(2) Since the outer dimensions of the lower-floor building units 21 and 22 and the upper-floor building unit 23 do not change, those modules can be unified, their parts and storage can be shared, and their productivity And no inconvenience in transportation.
[0047]
(3) In the above (1), by setting the plate thickness of the pillars 21A, 22A of the lower-floor building units 21, 22 to be larger than the plate thickness of the pillar 23A of the upper-floor building unit 23, the lower-floor building unit 21 , 22 can further improve the yield strength of the columns 21A and 22A.
[0048]
(4) The outer dimension of the cross section is small by matching the outdoor side surface of the pillars 21A and 22A of the lower floor building units 21 and 22 with the outdoor side surface of the pillar 23A of the upper floor building unit 23 in front view. The pillars 23A of the floor building unit 23 are arranged on the outdoor side, and the indoor space of the upper floor building unit 23 can be taken wider.
[0049]
(5) Guide pins 41A and 51A for positioning the upper and lower floors are set on the axis of the pillar 23A of the upper floor building unit 23 having a small cross-sectional dimension. Therefore, when a building unit having the same specifications as the upper floor building unit 23 is to be applied to the upper and lower floors of the lower layer in the unit building 10, the cores 61A and 62A of the upper and lower floor building units 61 and 62 are used as the axis cores. The building units 62 and 62 on the upper and lower floors can be stably aligned using the guide pins that are positioned. That is, the standard building unit that can be used together with both the upper building unit 23 and the lower building unit 61, 62 of the high-rise part while ensuring the stability of the lamination of the unit building 10 with the building units 23, 61, 62 of the same specification. Thus, the number of parts can be reduced by sharing the building unit and sharing the parts such as the cover plate attached to the end of the pillar and having the guide pin or the guide hole.
[0050]
The first-floor building unit 21 and the second-floor building unit 22 and the third-floor building unit 23 that constitute the high-rise section 20 in the three-floor unit building 10 of FIG. 1 are pillars of the first-floor building unit 21 and the second-floor building unit 22. The outer dimensions of the cross sections of 21A and 22A are, for example, 120 mm × 120 mm as described above, and the outer dimensions of the cross section of the pillar 23A of the third-floor building unit 23 are, for example, 100 mm × 100 mm as described above. At this time, since the first floor building unit 21 and the second floor building unit 22 and the third floor building unit 23 have the same external dimensions in plan view as described above, the opposing columns 21A in the first floor building unit 21 , 21A (the spacing between the opposing pillars 22A, 22A in the second floor building unit 22 is the same) is 20 mm shorter than the spacing between the opposing pillars 23A, 23A in the third floor building unit 23. For this reason, the distance between the opposing pillars 21A and 21A in the first-floor building unit 21 (the same as the distance between the opposing pillars 22A and 22A in the second-floor building unit 22) and the distance between the opposing pillars 23A and 23A in the third-floor building unit 23 In order to cope with the above difference, it is conceivable that the length of the floor beam 21B and the ceiling beam 21C of the first floor building unit 21 is 40 mm shorter than the length of the floor beam 23B and the ceiling beam 23C of the third floor building unit 23 in total length. However, in this case, the number of types of beams (floor beams 21B to 23B and ceiling beams 21C to 23C) constituting the building units 21 to 23 becomes extremely large for the reason described later. Therefore, in order to reduce the number of parts constituting the building units 21 to 23, the column and beam joints of the building units 21 to 23 are modified as shown in FIGS.
