It can be extended.

本発明を適用した板状集合住宅の柱梁構造1は、下階Fdの上部に配置される梁間鉄骨梁2の上方に、上階Fuの下部に配置される桁行鉄骨梁3が設けられることで、桁行鉄骨梁3が各階の上方から垂れ壁のように設けられないものとなり、住戸等の所有者等の視界を遮ることなく、共有部分SのバルコニーB及び通路Cの手摺壁等の壁体80の内部に桁行鉄骨梁3を設けることができる。   In the column-beam structure 1 of the plate-like apartment to which the present invention is applied, the girder steel beam 3 arranged in the lower part of the upper floor Fu is provided above the inter-beam steel beam 2 arranged in the upper part of the lower floor Fd. Therefore, the girder steel beam 3 cannot be provided from the upper side of each floor like a hanging wall, and walls such as the balcony B of the common portion S and the handrail wall of the passage C do not obstruct the view of the owner of the dwelling unit or the like. The girder steel beam 3 can be provided inside the body 80.

これに対して、従来の柱梁構造9は、図14に示すように、梁間方向Zに延びる構造部材として鉄骨梁を設けることなく、コンクリート製の耐力壁91を戸境壁Dに設けるものであり、鉄筋コンクリート柱90に耐力壁91が接合される部位まで、共有部分Sの通路Cを確保するための開口箇所を耐力壁91に形成させることができないことから、専有部分Pの4隅に鉄筋コンクリート柱90を配置せざるを得ないものとなっていた。   On the other hand, in the conventional column-beam structure 9, as shown in FIG. 14, a concrete load bearing wall 91 is provided on the boundary wall D without providing a steel beam as a structural member extending in the inter-beam direction Z. Since there is no opening in the bearing wall 91 for securing the passage C of the common portion S up to the portion where the bearing wall 91 is joined to the reinforced concrete column 90, the reinforced concrete is provided at the four corners of the exclusive portion P. The pillar 90 had to be arranged.

また、従来の柱梁構造9は、桁行方向Xに延びる構造部材として鉄骨梁を設けることなく、桁行方向Xに延びる鉄筋コンクリート梁92を各階の上部に配置させて、鉄筋コンクリート柱90に鉄筋コンクリート梁92を接合させるものであるため、鉄筋コンクリート梁92が各階の上方から垂れ壁のように設けられるものとなっていた。   Further, in the conventional column-beam structure 9, without providing a steel beam as a structural member extending in the girder row direction X, a reinforced concrete beam 92 extending in the girder row direction X is arranged at the upper part of each floor, and the reinforced concrete beam 92 is attached to the reinforced concrete pillar 90. Since they are to be joined, the reinforced concrete beams 92 are provided like a hanging wall from above each floor.

このため、従来の柱梁構造9は、専有部分Pの4隅に鉄筋コンクリート柱90が配置される場合に、バルコニーBに出入りするための開口部Aや、通路Cから出入りするための玄関Eが、鉄筋コンクリート梁92で上方から部分的に塞がれるものとなるため、開口部Aや玄関Eで所定の開口高さを確保するために、各階の階高Hを高くする必要が生じていた。   Therefore, in the conventional beam-column structure 9, when the reinforced concrete columns 90 are arranged at the four corners of the exclusive portion P, the opening A for entering and exiting the balcony B and the entrance E for entering and exiting the passage C are provided. Since it is partially blocked from above by the reinforced concrete beam 92, it is necessary to increase the floor height H of each floor in order to secure a predetermined opening height at the opening A and the entrance E.

また、従来の柱梁構造9は、仮に、共有部分SのバルコニーBや通路Cに鉄筋コンクリート柱90が設けられる場合であっても、鉄筋コンクリート柱90に接合される鉄筋コンクリート梁92が、各階の上方から垂れ壁のように設けられることで、住戸等の所有者等の視界を遮るものとなり、所定の視界を確保するために、各階の階高Hを高くする必要が生じていた。   Further, in the conventional column-beam structure 9, even if the balcony B or the passage C of the common portion S is provided with the reinforced concrete columns 90, the reinforced concrete beams 92 joined to the reinforced concrete columns 90 are arranged from above each floor. Since it is provided like a hanging wall, it obstructs the view of the owner of a dwelling unit or the like, and it has been necessary to increase the floor height H of each floor in order to secure a predetermined view.

本発明を適用した板状集合住宅の柱梁構造1は、図7に示すように、桁行方向Xに延びる桁行鉄骨梁3が、専有部分Pに設けられることなく、共有部分Sに設けられるものとなるように、板状集合住宅8の桁行外周部81に沿って配置されることで、専有部分Pの室内空間に桁行鉄骨梁3の梁型を形成させないものとなる。また、本発明を適用した板状集合住宅の柱梁構造1は、梁間方向Zに延びる梁間鉄骨梁2が、戸境壁Dの内部にフランジ幅全体が収まるように設けられることで、専有部分Pの室内空間に梁間鉄骨梁2の梁型を形成させないものとなる。   In the column-beam structure 1 of the plate-like housing to which the present invention is applied, as shown in FIG. 7, the girder steel beam 3 extending in the girder direction X is provided in the common portion S without being provided in the exclusive portion P. By arranging along the girder row outer peripheral portion 81 of the plate-like apartment 8 so that the girder-shaped steel beam 3 is not formed in the indoor space of the exclusive portion P. Further, in the column-beam structure 1 of the plate-like apartment to which the present invention is applied, the inter-beam steel beam 2 extending in the inter-beam direction Z is provided so that the entire flange width fits inside the boundary wall D. The beam shape of the inter-beam steel beam 2 is not formed in the P indoor space.

これにより、本発明を適用した板状集合住宅の柱梁構造1は、各々の専有部分Pに梁間鉄骨梁2及び桁行鉄骨梁3の梁型を形成させないものとして、専有部分Pの室内空間を広く確保することで、各々の専有部分Pの機能性や美観性を向上させて、マンション等の板状集合住宅の付加価値を高めることが可能となる。   As a result, in the column-beam structure 1 of the plate-like apartment to which the present invention is applied, the interior space of the exclusive portion P is defined by assuming that the beam shapes of the inter-beam steel beam 2 and the girder steel beam 3 are not formed in each of the exclusive portions P. By securing a wide area, it is possible to improve the functionality and aesthetics of each exclusive portion P and increase the added value of a plate-shaped collective housing such as an apartment.

本発明を適用した板状集合住宅の柱梁構造1は、下階Fdの上部に配置される梁間鉄骨梁2の上方に、上階Fuの下部に配置される桁行鉄骨梁3が設けられることで、各階の階高Hを高くすることを必要としないで、共有部分Sの通路Cが梁間鉄骨梁2で塞がれることなく、また、通路Cの足元に梁間鉄骨梁2による段差を形成させないものとなるとともに、桁行鉄骨梁3で住戸等の所有者等の視界が遮られないものとしながら、開口部Aや玄関Eで所定の開口高さを確保することができるものとなる。   In the column-beam structure 1 of the plate-like apartment to which the present invention is applied, the girder steel beam 3 arranged in the lower part of the upper floor Fu is provided above the inter-beam steel beam 2 arranged in the upper part of the lower floor Fd. Therefore, it is not necessary to increase the floor height H of each floor, the passage C of the common portion S is not blocked by the inter-beam steel beam 2, and a step due to the inter-beam steel beam 2 is formed at the foot of the passage C. In addition, the girder steel beam 3 does not obstruct the view of the owner of a dwelling unit or the like, and the opening A and the entrance E can secure a predetermined opening height.

これにより、従来の柱梁構造9は、開口部Aや玄関Eで所定の開口高さを確保等するために、各階の階高Hを最低でも3m程度確保することが必要となっていたのに対して、本発明を適用した板状集合住宅の柱梁構造1は、各階の階高Hを2.7m程度確保すれば十分なものとなる。例えば、45m程度の全体高さを有する板状集合住宅8においては、従来の柱梁構造9が最大でも15階建となっていたのに対して、本発明を適用した板状集合住宅の柱梁構造1が16階建程度とすることもできる。   As a result, in the conventional beam structure 9, it is necessary to secure a floor height H of each floor of at least 3 m in order to secure a predetermined opening height at the opening A and the entrance E. On the other hand, in the column-beam structure 1 of the plate-like apartment to which the present invention is applied, it is sufficient to secure the floor height H of each floor of about 2.7 m. For example, in the plate-shaped apartment house 8 having an overall height of about 45 m, the conventional column-beam structure 9 has a maximum of 15 stories, whereas the pillar-shaped apartment house to which the present invention is applied has columns. The beam structure 1 may have about 16 stories.
