Description
この発明は、主として木造住宅において、一般床部に対して段差が生じた状態で設けられるスキップフロアの構造に関する。
The present invention mainly relates to the structure of a skip floor provided in a wooden house in a state where a step is generated with respect to a general floor portion.
住宅内において、一般床部との間に段差を生じるスキップフロアを設ける場合、地震等が発生したときには、一般床部側とスキップフロア側との間で水平力が効率良く伝達されず、それぞれ別々な動きが生じることになり、特に一般床部とスキップフロアの境界部分すなわち段差部分において破損が生じ易いといった問題がある。
When a skip floor that creates a step between the general floor and the general floor is provided in the house, horizontal force is not efficiently transmitted between the general floor side and the skip floor side when an earthquake occurs, and each is separate. There is a problem that damage is likely to occur especially at the boundary portion between the general floor portion and the skip floor, that is, the stepped portion.
従って、このような問題を解消するために、構造上種々の補強対策が必要となるが、現状では、スキップフロアに関する公的な設計基準は見当たらず、数少ない指針が参考になる程度である。
Therefore, in order to solve such problems, various structural reinforcement measures are required, but at present, there are no official design standards for skip floors, and only a few guidelines can be used as a reference.
それらの指針を参照すると、スキップフロアを設ける場合には、図５に示すように、一般床部(31)側の外壁面(32)とスキップフロア(33)側の外壁面(34)とに跨って構造用合板(35)(35)を取り付けて、外壁面(32)(34)同士を一体化することで、一般床部(31)側とスキップフロア(33)側とを連動させるといった提案がなされている。
With reference to those guidelines, when a skip floor is provided, as shown in FIG. 5, the outer wall surface (32) on the general floor portion (31) side and the outer wall surface (34) on the skip floor (33) side By attaching structural plywood (35) (35) across and integrating the outer wall surfaces (32) (34), the general floor (31) side and the skip floor (33) side are linked. Proposals have been made.
しかしながら、上記のように構造用合板(35)(35)を取り付ける構造では、一般床部(31)側の外壁面(32)とスキップフロア(33)側の外壁面(34)を同一面上に配置する必要がある。しかも、構造用合板(35)(35)があるため、外壁面(32)(34)の境界部分付近に開口部(36)(36)を設けることができないといったように、建物形態における制約が多く、設計の自由度が狭められていた。
However, in the structure in which the structural plywood (35) (35) is attached as described above, the outer wall surface (32) on the general floor portion (31) side and the outer wall surface (34) on the skip floor (33) side are on the same surface. Need to be placed in. Moreover, because of the structural plywood (35) (35), there are restrictions on the building form, such as the fact that openings (36) (36) cannot be provided near the boundaries of the outer wall surfaces (32) (34). In many cases, the degree of freedom in design was narrowed.
そこで、この発明は、上記の不具合を解消して、一般床部側との間で水平力を効率良く伝達して、地震等の発生時における一般床部との境界部分での破損を抑えることができ、しかも建物形態における制約を少なくして、設計の自由度を高めることができるスキップフロア構造の提供を目的とする。

It is characterized in that a transmission beam for transmitting a horizontal force from the outer peripheral floor beam to the abdominal winding beam is interposed at a key point between the outer peripheral floor beam and the outer peripheral floor beam. Specifically, at least one transmission beam is arranged on each side of the skip floor, and the transmission beam is arranged directly under the bearing wall provided on the abdominal winding beam. Furthermore, the transmission beam is joined to the outer floor beam and the belly band beam by using a tenon.

以上の説明から明らかなように、この発明では、スキップフロアの外周床梁にかかる水平力が、伝達梁を介して、一般床部の床梁と同じ高さレベルに配された腹巻梁へ伝達されて、スキップフロアと一般床部とを一体的に連動させることができる。このため、従来の指針に示すような構造用合板を設けなくても、一般床部とスキップフロアとの間の境界部分の破損を防止することができ、一般床部側の外壁面と、スキップフロア側の外壁面とをずらした状態で配置したり、境界部分付近に開口部を設けることができるといったように、建物形態における制約が少なくなり、設計の自由度を高めることができる新たなスキップフロア構造計画指針を確立することができる。 (The invention's effect)
As is clear from the above description, in the present invention, the horizontal force applied to the outer peripheral beam of the skip floor is transmitted to the abdominal winding beam arranged at the same height level as the floor beam of the general floor through the transmission beam. Therefore, the skip floor and the general floor can be integrally linked. Therefore, even if the structural plywood as shown in the conventional guideline is not provided, it is possible to prevent the boundary portion between the general floor and the skip floor from being damaged, and the outer wall surface on the general floor side and the skip can be prevented. A new skip that can increase the degree of freedom in design by reducing restrictions on the building form, such as arranging it in a state where it is offset from the outer wall surface on the floor side or providing an opening near the boundary part. Floor structure planning guidelines can be established.
