In this building, each of the adjacent beams is provided with a rigid floor plate (connecting member), and by connecting these rigid floor plates, the rigidity of the floor of the building against horizontal loads is ensured.
ところで、上記特許文献１に記載の発明では、梁側から伝達される荷重を剛床プレートで支持しているが、この荷重による負荷の大きさが、剛床プレート同士の連結部と、剛床プレートと梁との連結部とで異なることが考えられる。そして、剛床プレートの厚さを剛床プレートにおける最も負荷が大きい箇所を基準に設定すると、剛床プレート全体では過剰品質となることが考えられる。 By the way, in the invention described in Patent Document 1, the load transmitted from the beam side is supported by the rigid floor plate, but the magnitude of the load due to this load is It is conceivable that the connection between the plate and the beam is different. If the thickness of the rigid floor plate is set based on the location on the rigid floor plate where the load is the highest, it is conceivable that the entire rigid floor plate will be of excessive quality.
本発明は上記事実を考慮し、建物の床部の水平荷重に対する剛性を確保しつつ、梁同士を連結する連結部材の品質が過剰品質となることを抑制することができる建物の床構造及び建物を得ることが目的である。 In consideration of the above facts, the present invention provides a floor structure for a building and a building that can suppress the quality of connecting members that connect beams from becoming excessive while ensuring the rigidity of the floor of the building against horizontal loads. The purpose is to obtain.
第１の態様に係る建物の床構造は、建物下方側から建物の床部の一部を構成する床板を支持すると共に、互いに対して平行に延在する一対の梁と、板厚方向を建物高さ方向とされた第１片部と、当該第１片部から建物高さ方向に延出された第２片部とを備え、建物高さ方向から見て前記梁と交差する方向に延在すると共に、一端部が一方の前記梁にピン接合され、他端部が他方の前記梁にピン接合された第１連結部材と、板厚方向を建物高さ方向とされた第３片部と、当該第３片部から建物高さ方向に延出された第４片部とを備え、建物高さ方向から見て前記梁及び前記第１連結部材と交差する方向に延在すると共に、一端部が前記他方の前記梁にピン接合され、他端部が前記一方の前記梁にピン接合され、中央部が当該第１連結部材の中央部とピン接合された第２連結部材と、を有している。 The floor structure of a building according to the first aspect supports a floor plate constituting a part of the floor of the building from the lower side of the building, and includes a pair of beams extending parallel to each other and a plate thickness direction extending toward the building. A first piece extends in the height direction, and a second piece extends in the building height direction from the first piece, and extends in a direction intersecting the beam when viewed from the building height direction. a first connecting member having one end portion pin-jointed to one of the beams and the other end portion pin-joining the other beam; and a third piece portion whose plate thickness direction is the building height direction. and a fourth piece extending in the building height direction from the third piece, extending in a direction intersecting the beam and the first connecting member when viewed from the building height direction, a second connecting member having one end portion pin-joined to the other beam, the other end portion pin-joining to the one beam, and a center portion pin-joining the center portion of the first connecting member; have.
第１の態様に係る建物の床構造では、互いに対して平行に延在する一対の梁によって、建物の床部の一部を構成する床板が、建物下方側から支持されている。 In the building floor structure according to the first aspect, a floor plate forming part of the floor of the building is supported from the lower side of the building by a pair of beams extending parallel to each other.
ところで、建物への水平荷重の入力時において、一対の梁のうち一方の梁に負荷が集中することを抑制するには、一対の梁間において水平荷重を伝達可能であることが好ましい。この点、一対の梁のそれぞれに剛床プレートを設けると共に、これらの剛床プレート同士を連結することで、一対の梁間において水平荷重を伝達可能な構成とすることが考えられる。 By the way, in order to suppress the load from being concentrated on one of the pair of beams when a horizontal load is input to the building, it is preferable that the horizontal load can be transmitted between the pair of beams. In this regard, it is conceivable to provide a rigid floor plate for each of the pair of beams and to connect these rigid floor plates to each other so that a horizontal load can be transmitted between the pair of beams.
しかしながら、このような構成では、剛床プレートの厚さを剛床プレートにおける最も負荷が大きい箇所を基準に設定すると、剛床プレート全体では過剰品質となることが考えられる。 However, in such a configuration, if the thickness of the rigid floor plate is set based on the location on the rigid floor plate where the load is the highest, the overall quality of the rigid floor plate may be excessive.
ここで、本態様では、一対の梁が第１連結部材及び第２連結部材を介して連結されている。詳しくは、第１連結部材は、建物高さ方向から見て梁と交差する方向に延在している。そして、第１連結部材の一端部が一方の梁にピン接合されており、第１連結部材の他端部が他方の梁にピン接合されている。 Here, in this aspect, the pair of beams are connected via the first connecting member and the second connecting member.

次に、本実施形態の作用並びに効果を説明する。
<Actions and effects of this embodiment>
Next, the operation and effects of this embodiment will be explained.
本実施形態では、図２に示されるように、互いに対して平行に延在する一対の梁２０によって、床部２４の一部を構成する床板２６が、第３方向他方側から支持されている。 In this embodiment, as shown in FIG. 2, a floor plate 26 forming part of the floor section 24 is supported from the other side in the third direction by a pair of beams 20 extending parallel to each other. .
ところで、建物１０への水平荷重の入力時において、一対の梁２０のうち一方の梁２０に負荷が集中することを抑制するには、一対の梁２０間において水平荷重を伝達可能であることが好ましい。この点、一対の梁２０のそれぞれに剛床プレートを設けると共に、これらの剛床プレート同士を連結することで、一対の梁２０間において水平荷重を伝達可能な構成とすることが考えられる。 By the way, in order to prevent the load from concentrating on one of the pair of beams 20 when a horizontal load is input to the building 10, it is necessary to be able to transmit the horizontal load between the pair of beams 20. preferable. In this regard, it is conceivable to provide a rigid floor plate for each of the pair of beams 20 and to connect these rigid floor plates to each other so that a horizontal load can be transmitted between the pair of beams 20.
しかしながら、このような構成では、剛床プレートの厚さを剛床プレートにおける最も負荷が大きい箇所を基準に設定すると、剛床プレート全体では過剰品質となることが考えられる。 However, in such a configuration, if the thickness of the rigid floor plate is set based on the location on the rigid floor plate where the load is the highest, the overall quality of the rigid floor plate may be excessive.
ここで、本実施形態では、図１に示されるように、一対の梁２０が第１連結部材２８及び第２連結部材３０を介して連結されている。詳しくは、第１連結部材２８は、第３方向から見て梁２０と交差する方向に延在している。そして、第１連結部材２８の一端部２８Ｃが一方の梁２０にピン接合されており、第１連結部材２８の他端部２８Ｄが他方の梁２０にピン接合されている。 Here, in this embodiment, as shown in FIG. 1, a pair of beams 20 are connected via a first connecting member 28 and a second connecting member 30. Specifically, the first connecting member 28 extends in a direction intersecting the beam 20 when viewed from the third direction. One end 28C of the first connecting member 28 is pin-jointed to one beam 20, and the other end 28D of the first connecting member 28 is pin-joined to the other beam 20.
一方、第２連結部材３０は、第３方向から見て梁２０及び第１連結部材２８と交差する方向に延在している。そして、第２連結部材３０の一端部３０Ｃが他方の梁２０にピン接合されており、第２連結部材３０の他端部３０Ｄが一方の梁２０にピン接合されており、第２連結部材３０の中央部３０Ｅが第１連結部材２８の中央部２８Ｅとピン接合されている。 On the other hand, the second connecting member 30 extends in a direction intersecting the beam 20 and the first connecting member 28 when viewed from the third direction. One end 30C of the second connecting member 30 is pin-jointed to the other beam 20, the other end 30D of the second connecting member 30 is pin-jointed to one of the beams 20, and the second connecting member 30 A central portion 30E of the first connecting member 28 is pin-jointed to a central portion 28E of the first connecting member 28.
このため、本実施形態では、第１連結部材２８及び第２連結部材３０を介して一対の梁２０間で水平荷重が伝達されるとき、第１連結部材２８及び第２連結部材３０には、引張荷重又は圧縮荷重が主に作用するため、これらの連結部材の断面形状を、その延在方向において一定にすることができる。 Therefore, in this embodiment, when a horizontal load is transmitted between the pair of beams 20 via the first connecting member 28 and the second connecting member 30, the first connecting member 28 and the second connecting member 30 have Since a tensile load or a compressive load mainly acts, the cross-sectional shape of these connecting members can be made constant in the direction of their extension.
また、第１連結部材２８は、板厚方向を第３方向とされた下壁部２８Ａと、下壁部２８Ａから第３方向に延出された側壁部２８Ｂとを備えており、第２連結部材３０は、板厚方向を第３方向とされた下壁部３０Ａと、下壁部３０Ａから第３方向に延出された側壁部３０Ｂとを備えている。このため、梁２０から伝達される荷重によって、第１連結部材２８及び第２連結部材３０が座屈することを抑制することができる。したがって。本実施形態では、建物１０の床部２４の水平荷重に対する剛性を確保しつつ、梁２０同士を連結する第１連結部材２８及び第２連結部材３０の品質が過剰品質となることを抑制することができる。 Further, the first connecting member 28 includes a lower wall portion 28A whose third direction is the plate thickness direction, and a side wall portion 28B extending in the third direction from the lower wall portion 28A. The member 30 includes a lower wall portion 30A whose third direction is the thickness direction, and a side wall portion 30B extending in the third direction from the lower wall portion 30A. Therefore, buckling of the first connecting member 28 and the second connecting member 30 due to the load transmitted from the beam 20 can be suppressed. therefore. In this embodiment, it is possible to suppress the quality of the first connecting member 28 and the second connecting member 30 that connect the beams 20 from becoming excessive while ensuring the rigidity of the floor 24 of the building 10 against horizontal loads. I can do it.
また、本実施形態では、図２にも示されるように、梁２０が、その第３方向一方側の部分を構成する上側フランジ部２０Ａと、その第３方向他方側の部分を構成する下側フランジ部２０Ｂと、上側フランジ部２０Ａと下側フランジ部２０Ｂとを第３方向に繋ぐウェブ部２０Ｃとを含んで構成されている。 Further, in this embodiment, as shown in FIG. 2, the beam 20 has an upper flange portion 20A that constitutes a portion on one side in the third direction, and a lower flange portion 20A that constitutes a portion on the other side in the third direction. It is configured to include a flange portion 20B and a web portion 20C that connects the upper flange portion 20A and the lower flange portion 20B in the third direction.
そして、梁２０の上側フランジ部２０Ａ上には、床板２６が配置されている。また、第１連結部材２８及び第２連結部材３０は、一方の梁２０の下側フランジ部２０Ｂと、他方の梁２０の下側フランジ部２０Ｂとを連結している。このため、本実施形態では、床板２６の取付部材と、第１連結部材２８及び第２連結部材３０との間にスペースを確保することができる。したがって、本実施形態では、一対の梁２０を連結する第１連結部材２８及び第２連結部材３０が、床板２６の取付部材と干渉することを抑制することができる。 A floor plate 26 is arranged on the upper flange portion 20A of the beam 20. Further, the first connecting member 28 and the second connecting member 30 connect the lower flange portion 20B of one beam 20 and the lower flange portion 20B of the other beam 20. Therefore, in this embodiment, a space can be secured between the attachment member of the floorboard 26 and the first connecting member 28 and the second connecting member 30. Therefore, in this embodiment, the first connecting member 28 and the second connecting member 30 that connect the pair of beams 20 can be prevented from interfering with the attachment member of the floorboard 26.
また、図１に示されるように、本実施形態では、第１連結部材２８の一端部２８Ｃにおいて、下壁部２８Ａが、第２連結部材３０の下壁部３０Ａと同じ厚さのワッシャ３４を介して、一方の梁２０における下側フランジ部２０Ｂ上に配置されている。一方、第１連結部材２８の他端部２８Ｄでは、下壁部２８Ａが、ワッシャ３４を介して、他方の梁２０における下側フランジ部２０Ｂ上に配置されている。 Further, as shown in FIG. 1, in this embodiment, the lower wall portion 28A has a washer 34 having the same thickness as the lower wall portion 30A of the second connecting member 30 at one end portion 28C of the first connecting member 28. It is disposed on the lower flange portion 20B of one of the beams 20 via the lower flange portion 20B. On the other hand, at the other end 28D of the first connecting member 28, the lower wall 28A is placed on the lower flange 20B of the other beam 20 with the washer 34 in between.
また、第２連結部材３０の一端部３０Ｃにおいて下壁部３０Ａは、他方の梁２０における下側フランジ部２０Ｂ上に下側フランジ部２０Ｂと接触した状態で配置されている。一方、第２連結部材３０の他端部３０Ｄでは、下壁部３０Ａが、一方の梁２０における下側フランジ部２０Ｂ上に下側フランジ部２０Ｂと接触した状態で配置されている。このため、第３方向において、下壁部２８Ａの下面と下壁部３０Ａの上面とが同じ位置に位置する。 Further, the lower wall portion 30A at the one end portion 30C of the second connecting member 30 is disposed on the lower flange portion 20B of the other beam 20 in a state in which it is in contact with the lower flange portion 20B. On the other hand, at the other end 30D of the second connecting member 30, the lower wall 30A is disposed on the lower flange 20B of one of the beams 20, in contact with the lower flange 20B. Therefore, in the third direction, the lower surface of the lower wall section 28A and the upper surface of the lower wall section 30A are located at the same position.
そして、第１連結部材２８と第２連結部材３０との連結箇所において、側壁部３０Ｂには、第１連結部材２８を挿入可能な凹部４２が形成されており、凹部４２には、第１連結部材２８が挿入される。このとき、第２連結部材３０の下壁部３０Ａ上には、第１連結部材２８の下壁部２８Ａが下壁部３０Ａと接触した状態で配置されている。その結果、第１連結部材２８及び第２連結部材３０を下側フランジ部２０Ｂ上に配置することができる。 At the connection point between the first connection member 28 and the second connection member 30, a recess 42 into which the first connection member 28 can be inserted is formed in the side wall portion 30B.
