Abstract

PROBLEM TO BE SOLVED: To provide a floor structure capable of excellently transmitting a load between a beam and a column without complicating a transmission mechanism of the load of the entire frame even when there is a floor part of a different height in an intermediate story.SOLUTION: A floor receiving part 50 is configured to be suspend and supported only by a beam 30. In such a manner, since the floor receiving part 50 is suspended and supported only by the beam 30 and receives a floor part 40, even in the case that a horizontal load is inputted to the floor part 40, all the load is transmitted through the floor receiving part 50 to the beam 30, and the load is not transmitted to the middle part of columns 20a and 20B or the like. Thus, the load from the floor part 40 is transmitted through the floor receiving part 50 to the beam 30 and the columns 20A and 20B similarly to a general floor part PF1. Since the load is transmitted similarly to the general floor part PF1, the load is excellently transmitted between the beam and the column without complicating the transmission mechanism of the load of the entire frame.

Description

本発明は、住宅等の建物の床構造に関する。   The present invention relates to a floor structure of a building such as a house.

従来、住宅等の建物の中間階において、一般床部との間に段差を生じる床下げ部を設ける場合、地震等が発生したときには、一般床部側と床下げ部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、特に一般床部と床下げ部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。   Conventionally, in the case where an underfloor is provided on the intermediate floor of a building, such as a house, that creates a step with the general floor, when an earthquake occurs, the horizontal force between the general floor and the underfloor Is not transmitted efficiently, and separate movements occur. In particular, there is a problem that breakage is likely to occur at a boundary portion between the general floor portion and the floor lowering portion, that is, a step 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、例えば特許文献1には、床下げ部の周囲に外周床梁を設け、該外周床梁の上方に一般床部の床梁と同じ高さレベルとした腹巻梁を架構し、該腹巻梁と外周床梁との間の要所要所に、外周床梁から腹巻梁へ水平力を伝達するための伝達梁を介在させたスキップフロア構造が開示されている。   Therefore, in order to solve such a problem, various reinforcement measures are necessary in terms of structure. For example, in Patent Document 1, an outer peripheral floor beam is provided around the floor-lowering portion, and the upper floor beam is disposed above the outer peripheral floor beam. A structure for constructing a bellows beam with the same level as the floor beam on the general floor, and transmitting the horizontal force from the outer floor beam to the bellows beam at the required point between the belly beam and the outer floor beam. A skip floor structure with a beam interposed is disclosed.

特開2003-166289号公報JP 2003-166289 A

しかしながら、上記特許文献1のスキップフロア構造においては、一般床部と同じ高さに設けられる腹巻梁のみならず該腹巻梁の下方に設けられて床下げ部を支持する外周床梁の端部も柱に連結されている構成である。従って、床下げ部に入力される荷重は腹巻梁のみならず外周床梁からも柱に伝達されることとなり、これらに連結される柱は、腹巻梁と外周床梁の両方から荷重を受け、或いはこれらが一体となった大断面の梁部材としてこれらからの荷重が伝達されることとなる。これによって、床下げ部の荷重の伝達が一般床部とは著しく異なるものとなり、建物全体として健全な荷重伝達が阻害されるのみならず、当該架構を実際に実現するための構造計算が大幅に複雑化するという問題がある。   However, in the skip floor structure of Patent Document 1, not only the bellows beam provided at the same height as the general floor portion, but also the end portion of the outer peripheral floor beam provided below the bellows beam and supporting the floor lowering portion. It is the structure connected with the pillar. Therefore, the load input to the floor lowering part is transmitted to the column not only from the bellows beam but also from the outer floor beam, and the columns connected to these receive the load from both the bellows beam and the outer floor beam, Or the load from these will be transmitted as a beam member of the large cross section in which these were united. As a result, the load transmission of the floor-lowering part is significantly different from that of the general floor part, which not only hinders the sound load transmission as a whole building, but also greatly reduces the structural calculation to actually realize the frame. There is a problem of increasing complexity.

本発明は、このような問題を解決するためになされたものであり、中間階において、高さが異なる床部が存在する場合にも、架構全体の荷重の伝達機構を複雑化させることなく、梁柱間で良好に荷重を伝達することができる床構造を提供することを目的とする。   The present invention has been made to solve such a problem, and even when there are floor portions having different heights in the intermediate floor, without complicating the load transmission mechanism of the entire frame, An object of the present invention is to provide a floor structure capable of transmitting a load between beam columns.

本発明に係る床構造は、水平荷重を伝達可能な床部と、該床部の周囲に設けられて該床部を支持する複数の梁とを備え、少なくとも1の梁の端部が柱に接合されると共に、床部と梁との間には、梁にのみ吊り下げ支持されて床部を梁の天端よりも下方で受け、又は梁からのみ立ち上がって床部を梁の天端よりも上方で受ける床受け部が設けられていることを特徴とする。   A floor structure according to the present invention includes a floor portion capable of transmitting a horizontal load and a plurality of beams provided around the floor portion to support the floor portion, and an end portion of at least one beam is a column. In addition to being joined, the floor is supported only by the beam, and the floor is received below the top of the beam, or the floor is raised only from the beam and the floor from the top of the beam. Is also provided with a floor receiving portion that is received above.

本発明に係る床構造では、床受け部が、梁にのみ吊り下げ支持されて床部を受け、あるいは梁からのみ立ち上がって床部を受けている。従って、床部に水平荷重が入力される場合であっても、当該荷重はすべて床受け部を介して梁に伝達され、当該荷重が柱の中途部等に伝達されない構成となっている。これによって、高さが異なる床部が存在する場合であっても、当該床部からの荷重は、床受け部を介して、一般床部と同様に梁及び柱に伝達されることとなる。一般床部と同様に荷重の伝達が行われるため、架構全体の荷重の伝達機構が複雑化することなく梁柱間で良好に荷重を伝達することができる。   In the floor structure according to the present invention, the floor receiving portion is suspended and supported only by the beam and receives the floor portion, or stands only from the beam and receives the floor portion. Therefore, even when a horizontal load is input to the floor portion, the load is all transmitted to the beam through the floor receiving portion, and the load is not transmitted to the middle portion of the column. As a result, even when there are floor portions having different heights, the load from the floor portion is transmitted to the beams and columns through the floor receiving portion in the same manner as the general floor portion. Since the load is transmitted in the same manner as the general floor portion, the load can be transmitted between the beam columns without complicating the load transmission mechanism of the entire frame.

また、本発明に係る床構造において、床受け部は、梁の直下に吊り下げ支持されて当該梁にのみ支持される吊下げ部と、該吊下げ部に連結されて床部の側縁部を受ける床受け部材と、を備えていることが好ましい。これによれば、床受け部の吊下げ部材が梁の直下に設けられるので、床受け部材を介して支持される床部は、梁に支持される場合と同様の寸法でよく、当該床受け部に支持されることによって床部の寸法を変更する必要がない。従って、施工性の向上及び部材種類の増加の抑制を図ることができる。   Further, in the floor structure according to the present invention, the floor receiving portion is suspended and supported just below the beam and supported only by the beam, and the side edge portion of the floor portion connected to the suspension portion. And a floor receiving member for receiving. According to this, since the suspension member of the floor receiving portion is provided directly below the beam, the floor portion supported via the floor receiving member may have the same dimensions as those supported by the beam, It is not necessary to change the dimension of the floor by being supported by the part. Therefore, it is possible to improve the workability and suppress the increase in the types of members.

また、本発明に係る床構造において、吊下げ部は、梁と同一断面を有して床受け部材を支持する床受け梁と、該床受け梁と梁との間に設けられ、床受け梁と梁との間隔を調整する吊束と、を備えていることが好ましい。これによれば、床受け梁として梁を流用することができる。また、外壁等他の部材との関係で当該床受け部の高さ方向での調整を要する場合には、吊束によって調整することができ、床受け梁や床受け部材の高さや形状を変更させる必要がなく、これによっても部材種類の増加を抑制することができる。   Further, in the floor structure according to the present invention, the hanging portion is provided between the floor receiving beam having the same cross section as the beam and supporting the floor receiving member, and between the floor receiving beam and the floor receiving beam. It is preferable to provide a hanging bundle that adjusts the distance between the beam and the beam. According to this, a beam can be diverted as a floor receiving beam. In addition, when adjustment in the height direction of the floor receiving part is required in relation to other members such as the outer wall, it can be adjusted by a hanging bundle, and the height and shape of the floor receiving beam and floor receiving member can be changed. It is not necessary to make it, and the increase in the kind of member can also be suppressed by this.

また、本発明に係る床構造において、床受け部は、吊下げ部のうち、隣り合う部分、又は対向し合う部分を互いに連結する連結部材を備えていることが好ましい。これによれば、床受け部が連結部材を介して連結されることとなるので、床受け部及び床部の水平剛性の向上を図ることができる。   Moreover, the floor structure which concerns on this invention WHEREIN: It is preferable that the floor receiving part is provided with the connection member which mutually connects the adjacent part or the part which opposes among hanging parts. According to this, since the floor receiving part is connected via the connecting member, the horizontal rigidity of the floor receiving part and the floor part can be improved.

また、本発明に係る床構造において、床部の一方の端部が床受け部の一方側に支持されると共に、床部の他方の端部が床受け部の他方側に支持され、床受け部の一方側と他方側との間には、小梁が架設され、床受け部には、一方側及び他方側において、小梁の各端部の直上となる位置に、吊束がそれぞれ設けられていることが好ましい。これにより、床受け部の剛性を強化することができる。すなわち、床受け部は、吊束を介して梁に垂下されている状態であり、剛床に過大な水平力又は鉛直力が導入された場合に、想定以上に当該剛床に水平方向又は鉛直方向の振動を許容してしまう可能性がある。従って、床受け部の一方側と他方側で吊束同士が対向するような位置関係とし、当該対向させた位置間で小梁を架設することによって、一方側の梁〜床受け部の一方側の吊束〜床受け部の一方側の床受け梁〜小梁〜床受け部の他方側の床受け梁〜床受け部の他方側の吊束〜他方側の梁、までの一体性が高まる。その結果、剛性が高められ、床下げ部の耐振動性を高めることができる。   In the floor structure according to the present invention, one end of the floor portion is supported on one side of the floor receiving portion, and the other end portion of the floor portion is supported on the other side of the floor receiving portion. A small beam is installed between one side and the other side of the section, and a suspension bundle is provided on the floor receiving portion at a position directly above each end of the small beam on one side and the other side. It is preferable that Thereby, the rigidity of a floor receiving part can be strengthened. That is, the floor receiving part is suspended from the beam via the hanging bundle, and when an excessive horizontal force or vertical force is introduced to the rigid floor, the floor is horizontally or vertically more than expected. There is a possibility of allowing vibration in the direction. Therefore, by having a positional relationship such that the hanging bundles face each other on one side and the other side of the floor receiving part, and constructing a small beam between the opposed positions, the beam on one side to one side of the floor receiving part Integral from the suspended bundle to the floor receiving beam on one side of the floor receiving portion to the small beam to the floor receiving beam on the other side of the floor receiving portion to the hanging bundle on the other side of the floor receiving portion to the beam on the other side. . As a result, the rigidity is increased and the vibration resistance of the floor-lowering portion can be increased.

また、本発明に係る床構造において、小梁は、一対の床受け梁間に複数設けられており、隣り合う小梁の間には、タイバーが架設されていることが好ましい。これにより、小梁と直交する方向の剛性も高められ、床下げ部の耐振動性を更に向上させることができる。   In the floor structure according to the present invention, it is preferable that a plurality of small beams are provided between a pair of floor receiving beams, and a tie bar is provided between adjacent small beams. Thereby, the rigidity in the direction orthogonal to the beam is also increased, and the vibration resistance of the floor-lowering portion can be further improved.

本発明に係る床構造は、水平荷重を伝達可能な床部と、該床部の周囲に設けられて該床部を支持する複数の梁とを備え、床部と梁との間には、梁にのみ吊り下げ支持されて床部を梁の天端よりも下方で受け、又は梁からのみ立ち上がって床部を梁の天端よりも上方で受ける床受け部が設けられていることを特徴とする。   The floor structure according to the present invention includes a floor part capable of transmitting a horizontal load and a plurality of beams provided around the floor part to support the floor part, and between the floor part and the beam, A floor receiving portion is provided that is supported only by being suspended from the beam and receives the floor portion below the top end of the beam, or that rises only from the beam and receives the floor portion above the top end of the beam. And

本発明に係る床構造では、床受け部が、梁にのみ吊り下げ支持されて床部を受け、あるいは梁からのみ立ち上がって床部を受けている。従って、床部に水平荷重が入力される場合であっても、当該荷重はすべて床受け部を介して梁に伝達され、当該荷重が柱の中途部等に伝達されない構成となっている。これによって、高さが異なる床部が存在する場合であっても、当該床部からの荷重は、床受け部を介して、一般床部と同様に梁及び柱に伝達されることとなる。一般床部と同様に荷重の伝達が行われるため、架構全体の荷重の伝達機構が複雑化することなく梁柱間で良好に荷重を伝達することができる。   In the floor structure according to the present invention, the floor receiving portion is suspended and supported only by the beam and receives the floor portion, or stands only from the beam and receives the floor portion. Therefore, even when a horizontal load is input to the floor portion, the load is all transmitted to the beam through the floor receiving portion, and the load is not transmitted to the middle portion of the column. As a result, even when there are floor portions having different heights, the load from the floor portion is transmitted to the beams and columns through the floor receiving portion in the same manner as the general floor portion. Since the load is transmitted in the same manner as the general floor portion, the load can be transmitted between the beam columns without complicating the load transmission mechanism of the entire frame.

本発明によれば、中間階において、高さが異なる床部が存在する場合にも、架構全体の荷重の伝達機構を複雑化させることなく、梁柱間で良好に荷重を伝達することができる。   According to the present invention, even when floors having different heights exist on the intermediate floor, the load can be transmitted between the beam columns without complicating the load transmission mechanism of the entire frame. .

床受け梁54A,54B,54C,54Dは、梁30と同一断面を有しており、上下方向から見て対応する梁30と重なるように、梁30の直下に配置される。すなわち、床受け梁54A,54B,54C,54Dの天端54aと、対応する梁30の下端30bとが互いに平行をなすと共に、上下方向から見て互いに幅方向におけるずれがないように配置されている。これによって、床受け梁54A,54B,54C,54Dは、床部40を四辺から取り囲むように配置される。ここで、「同一断面」とは、梁の高さ(すなわち、ウェブの上下方向の大きさ)及び幅(すなわち、フランジの幅)が同一であることを意味し、ウェブやフランジの厚みまで同一であることは要しない。すなわち、ウェブやフランジの厚みは異なっていてもよい。また、床受け梁54A,54B,54C,54Dは、梁30と同一断面ではなく、幅が同じで高さが異なるもの(更には、高さが同じで幅が異なるもの)を用いてもよい。以上により、床受け梁54A,54B,54C,54Dは、梁30として用いたものと共通の梁部材、または建物の構築に用いられる他の部分の梁部材を適用することができる(すなわち、床受け梁54A,54B,54C,54Dのためだけの特別な梁部材を準備する必要がなくなる)。これによって、部品の共通化を図ることができる。   The floor receiving beams 54A, 54B, 54C, and 54D have the same cross section as the beam 30, and are disposed directly below the beam 30 so as to overlap with the corresponding beam 30 when viewed in the vertical direction. That is, the top ends 54a of the floor receiving beams 54A, 54B, 54C, and 54D and the lower ends 30b of the corresponding beams 30 are parallel to each other and arranged so as not to be displaced in the width direction when viewed from the top and bottom. Yes. Thereby, the floor receiving beams 54A, 54B, 54C, and 54D are arranged so as to surround the floor portion 40 from four sides. Here, “the same cross section” means that the height of the beam (that is, the size in the vertical direction of the web) and the width (that is, the width of the flange) are the same, and the thickness of the web and the flange is the same. It is not necessary to be. That is, the thickness of the web or flange may be different. Further, the floor receiving beams 54A, 54B, 54C, 54D may not be the same cross section as the beam 30, but may have the same width and different height (further, the same height and different width). . As described above, the floor receiving beams 54A, 54B, 54C, and 54D can be applied with a beam member that is the same as that used as the beam 30, or a beam member of another part that is used for building construction (that is, the floor member). (There is no need to prepare special beam members only for the receiving beams 54A, 54B, 54C, 54D). As a result, the parts can be shared.

具体的に、床受け梁54Aは、柱20A,20Bの間に配置される屋外側の梁30の直下に配置される。床受け梁54Aの一方の端部が、柱20Aと接触しないように当該柱20Aから離間することによって、柱20Aと床受け梁54Aとの間に隙間SP1が形成される。床受け梁54Aの他方の端部が、柱20Bと接触しないように当該柱20Bから離間することによって、柱20Bと床受け梁54Aとの間に隙間SP2が形成されている。床受け梁54Bは、屋外側の梁30と平行をなす屋内側の梁30の直下に配置される。床受け梁54Cは、柱20Aから屋内へ向かって垂直に延びる梁30の直下に配置される。床受け梁54Cの端部が、柱20Aと接触しないように当該柱20Aから離間することによって、柱20Aと床受け梁54Cとの間に隙間SP3が形成される。床受け梁54Dは、柱20Bから屋内へ向かって垂直に延びる梁30の直下に配置される。床受け梁54Dの端部が、柱20Bと接触しないように当該柱20Bから離間することによって、柱20Bと床受け梁54Dとの間に隙間SP4が形成される。なお、床受け梁54Cと床受け梁54Bとは、後述のジョイントピース77によって連結される。床受け梁54Dと床受け梁54Bとは、ジョイントピース77によって連結される。   Specifically, the floor receiving beam 54A is arranged directly below the outdoor beam 30 arranged between the pillars 20A and 20B. One end of the floor receiving beam 54A is separated from the column 20A so as not to contact the column 20A, thereby forming a gap SP1 between the column 20A and the floor receiving beam 54A. The other end of the floor receiving beam 54A is separated from the column 20B so as not to contact the column 20B, thereby forming a gap SP2 between the column 20B and the floor receiving beam 54A. The floor receiving beam 54 </ b> B is disposed directly below the indoor beam 30 that is parallel to the outdoor beam 30. The floor receiving beam 54C is disposed directly below the beam 30 extending vertically from the pillar 20A toward the indoor. By separating the end of the floor receiving beam 54C from the column 20A so as not to contact the column 20A, a gap SP3 is formed between the column 20A and the floor receiving beam 54C. The floor receiving beam 54D is disposed directly below the beam 30 that extends vertically from the pillar 20B toward the interior. By separating the end of the floor receiving beam 54D from the column 20B so as not to contact the column 20B, a gap SP4 is formed between the column 20B and the floor receiving beam 54D. The floor receiving beam 54C and the floor receiving beam 54B are connected by a joint piece 77 described later. The floor receiving beam 54D and the floor receiving beam 54B are connected by a joint piece 77.

The size of one side of the upper plate 57 and the bottom plate 58 matches the size of the beam 30 and the floor receiving beams 54A, 54B, 54C, 54D in the width direction. Since the wall portions orthogonal to each other in the vertical wall 59 are arranged at the centers of the side portions of the top plate 57 and the bottom plate 58, the top plate 57 and the bottom plate 58 are divided into four square regions by the vertical wall 59. . One through hole 61 is formed in each of the four regions. The four through holes 61 in the upper plate 57 and the bottom plate 58 of the suspended bundle 56 are formed at predetermined intervals at the lower end 30b of the beam 30 and the top ends 54a of the floor receiving beams 54A, 54B, 54C, 54D. The two through holes are formed with the same diameter and the same pitch. When fixing the beam 30 and the floor receiving beams 54A, 54B, 54C, 54D, the four through holes 61 of the upper plate 57 of the suspended bundle 56 are set to the four through holes at a predetermined position of the lower end 30b of the beam 30. Align and tighten with bolts and nuts. On the other hand, the four through holes 61 of the bottom plate 58 of the hanging bundle 56 are aligned with the four through holes at predetermined positions of the top ends 54a of the floor receiving beams 54A, 54B, 54C, 54D, and fastened with bolts and nuts. As a result, the suspended bundle 56 is joined to the floor panel 41 of the floor 40 by bolt joining in the vertical direction (tensile direction). In the example shown in FIG. 4, the suspension bundles 56 are arranged two at a predetermined interval with respect to each of the floor receiving beams 54A, 54B, 54C, 54D, but may be further increased. Further, depending on the separation distance between the beam 30 and the floor receiving beams 54A, 54B, 54C, 54D, a suspended bundle 56 having different sizes in the vertical direction may be used, or a plurality of the bundles may be used.

次に、本実施形態に係る床構造100の作用・効果について説明する。   Next, functions and effects of the floor structure 100 according to the present embodiment will be described.

本実施形態に係る床構造100では、床受け部50を構成する床受け梁54A,54B,54C,54D、吊束56、床受け部材52A,52B、連結部材53は、いずれも柱20A,20Bから離間しており柱20A,20Bの中途部によって直接支持されない構造となっている。従って、床受け部50は、梁30にのみ吊り下げ支持される構成となっている。このように、床受け部50が、梁30にのみ吊り下げ支持されて床部40を受けているため、床部40に水平荷重が入力される場合であっても、当該荷重はすべて床受け部50を介して梁30に伝達され、当該荷重が柱20A,20Bの中途部等に伝達されない構成となっている。更に、床部40が剛床機構42を備えており、床受け部50の床受け梁54A,54B,54C,54Dは梁30に対してボルト締めによって強固に固定されている。すなわち、梁30と、床受け部50と、床部40とが、高い剛性を有するように一体化された一つの剛体物として構成される。従って、地震時などにおいては、床部40や床受け部50ばかりが大きく揺れることで荷重が逃げることを防止し、梁30へ確実に荷重伝達を行うことができる。これによって、高さが異なる床部40が存在する場合であっても、当該床部40からの荷重は、床受け部50を介して、一般床部PF1と同様に梁30及び柱20A,20Bに伝達されることとなる。一般床部PF1と同様に荷重の伝達が行われるため、架構全体の荷重の伝達機構が複雑化することなく梁柱間で良好に荷重を伝達することができる。   In the floor structure 100 according to the present embodiment, the floor receiving beams 54A, 54B, 54C, 54D constituting the floor receiving portion 50, the hanging bundle 56, the floor receiving members 52A, 52B, and the connecting member 53 are all pillars 20A, 20B. It is the structure which is spaced apart from and is not directly supported by the middle part of pillar 20A, 20B. Therefore, the floor receiving portion 50 is configured to be supported by being suspended only by the beam 30. Thus, since the floor receiving portion 50 is supported by being suspended only by the beam 30 and receives the floor portion 40, even when a horizontal load is input to the floor portion 40, the load is all received by the floor receiving portion 50. The load is transmitted to the beam 30 through the portion 50, and the load is not transmitted to the middle portion of the columns 20A and 20B. Further, the floor portion 40 includes a rigid floor mechanism 42, and the floor receiving beams 54A, 54B, 54C, 54D of the floor receiving portion 50 are firmly fixed to the beam 30 by bolting. That is, the beam 30, the floor receiving portion 50, and the floor portion 40 are configured as one rigid body that is integrated so as to have high rigidity. Therefore, in the event of an earthquake or the like, it is possible to prevent the load from escaping because only the floor portion 40 and the floor receiving portion 50 are greatly shaken, and to transmit the load to the beam 30 reliably. As a result, even when there are floor portions 40 having different heights, the load from the floor portion 40 is transmitted through the floor receiving portion 50 in the same manner as the general floor portion PF1, and the beams 30 and the columns 20A and 20B. Will be transmitted. Since the load is transmitted in the same manner as the general floor portion PF1, the load can be favorably transmitted between the beam columns without complicating the load transmission mechanism of the entire frame.

また、本実施形態に係る床構造100において、床受け部50は、梁30の直下に吊り下げ支持されて当該梁30にのみ支持される吊下げ部51と、該吊下げ部51に連結されて床部40の床パネル41の側縁部41a,41bを受ける床受け部材52A,52Bと、を備えている。これによれば、床受け部50の吊下げ部材51が梁30の直下に設けられるので、床受け部材52A,52Bを介して支持される床パネル41は、梁30に支持される場合と同様の寸法でよく、当該床受け部材52A,52Bに支持されることによって床パネル41の寸法を変更する必要がない。具体的には、図6において仮想線で示すように、梁30に固定された金具90に載置することによって上面の高さ位置が梁30の上面30aと一致するように構成された一般床部PF2において用いられる床パネルと同じものを用いることができる。従って、施工性の向上及び部材種類の増加の抑制を図ることができる。   Further, in the floor structure 100 according to the present embodiment, the floor receiving unit 50 is suspended and supported directly below the beam 30 and is supported only by the beam 30, and is coupled to the suspension unit 51. Floor receiving members 52A and 52B for receiving side edge portions 41a and 41b of the floor panel 41 of the floor portion 40. According to this, since the suspension member 51 of the floor receiving portion 50 is provided immediately below the beam 30, the floor panel 41 supported via the floor receiving members 52A and 52B is the same as when supported by the beam 30. It is not necessary to change the dimension of the floor panel 41 by being supported by the floor receiving members 52A and 52B. Specifically, as shown by phantom lines in FIG. 6, a general floor configured such that the height position of the upper surface coincides with the upper surface 30 a of the beam 30 by being placed on the metal fitting 90 fixed to the beam 30. The same floor panel used in the part PF2 can be used. Therefore, it is possible to improve the workability and suppress the increase in the types of members.

また、本実施形態に係る床構造100において、吊下げ部51は、梁30と同一断面を有して床受け部材52A,52Bを支持する床受け梁54A,54B,54C,54Dと、該床受け梁54A,54B,54C,54Dと梁30との間に設けられ、床受け梁54A,54B,54C,54Dと梁30との間隔を調整する吊束56と、を備えている。これによれば、床受け梁54A,54B,54C,54Dとして梁30で用いている梁部材を流用することができる。また、外壁等他の部材との関係で当該床受け部50の高さ方向での調整を要する場合には、吊束56によって調整することができ、床受け梁54A,54B,54C,54Dや床受け部材52A,52Bの高さや形状を変更させる必要がなく、これによっても部材種類の増加を抑制することができる。   Further, in the floor structure 100 according to the present embodiment, the hanging portion 51 has the same cross section as the beam 30 and supports the floor receiving members 52A, 52B, and the floor receiving beams 54A, 54B, 54C, 54D, and the floor. A suspension bundle 56 is provided between the receiving beams 54A, 54B, 54C, 54D and the beam 30 and adjusts the distance between the floor receiving beams 54A, 54B, 54C, 54D and the beam 30. According to this, the beam member used with the beam 30 can be diverted as the floor receiving beams 54A, 54B, 54C, 54D. Further, when adjustment in the height direction of the floor receiving portion 50 is required in relation to other members such as an outer wall, it can be adjusted by the hanging bundle 56, and floor receiving beams 54A, 54B, 54C, 54D, It is not necessary to change the height and shape of the floor receiving members 52A and 52B, and this can also suppress an increase in the types of members.

また、本実施形態に係る床構造100において、床受け部50は、吊下げ部51のうち、隣り合う部分(互いに隣り合う床受け梁)、又は対向し合う部分(対向し合う床受け梁)を互いに連結する連結部材53を備えている。これによれば、床受け部50が連結部材53を介して連結されることとなるので、床受け部50及び床部40の水平剛性の向上を図ることができる。   Further, in the floor structure 100 according to the present embodiment, the floor receiving part 50 includes adjacent portions (floor receiving beams adjacent to each other) or facing portions (facing floor receiving beams facing each other) of the suspended portion 51. Are connected to each other. According to this, since the floor receiving part 50 will be connected via the connection member 53, the horizontal rigidity of the floor receiving part 50 and the floor part 40 can be improved.

本発明は、上述の実施形態に限定されるものではない。   The present invention is not limited to the embodiment described above.

例えば、図8,9に示すような変形例に係る床構造200を採用してもよい。   For example, you may employ | adopt the floor structure 200 which concerns on a modification as shown to FIG.

図8,9に示すように、変形例に係る床構造200は、上述の床構造100に加え、床受け部50の一方側と他方側の間に架設された小梁201と、隣り合う小梁201同士の間に架設されたタイバー202と、を備えている。床構造200では、床部40の一方の端部が床受け部50の一方側(ここでは、床受け梁54A側)に支持されると共に、床部40の他方の端部が床受け部50の他方側(ここでは、床受け梁54B側)に支持されており、その状態において、床受け部50の一方側と他方側との間に、小梁201が架設されている。また、床受け部50には、一方側及び他方側において、小梁201の各端部側の連結部203の直上となる位置に、吊束56がそれぞれ設けられている。また、小梁201は、一対の床受け梁54間に複数設けられており、隣り合う小梁201の間には、タイバー202が架設されている。   As shown in FIGS. 8 and 9, the floor structure 200 according to the modified example includes a small beam 201 adjacent to a small beam 201 laid between one side and the other side of the floor receiving part 50 in addition to the floor structure 100 described above. And a tie bar 202 constructed between the beams 201. In the floor structure 200, one end portion of the floor portion 40 is supported on one side (here, the floor receiving beam 54A side) of the floor receiving portion 50, and the other end portion of the floor portion 40 is supported on the floor receiving portion 50. The other side (here, the floor receiving beam 54B side) is supported, and in this state, the small beam 201 is installed between one side and the other side of the floor receiving part 50. In addition, on the floor receiving portion 50, on one side and the other side, suspension bundles 56 are respectively provided at positions that are directly above the connecting portions 203 on each end portion side of the small beam 201. A plurality of the small beams 201 are provided between the pair of floor receiving beams 54, and a tie bar 202 is installed between the adjacent small beams 201.

床受け梁54Aに固定された吊束56と、床受け梁54Bに固定された吊束56とは、梁54A,54B同士の対向方向において、同位置に配置される。小梁201は、当該吊束56が固定される位置において、床受け梁54Aと床受け梁54Bとの間に、床受け梁54C,54Dと平行となるように架設される。小梁201は、床受け梁54A,54B,54C,54Dと同一断面を有している。また、高さ方向においては、小梁201は、上面が床受け梁54A,54B,54C,54Dの上面と一致し、下面が床受け梁54A,54B,54C,54Dの下面と一致するように配置される。   The hanging bundle 56 fixed to the floor receiving beam 54A and the hanging bundle 56 fixed to the floor receiving beam 54B are arranged at the same position in the opposing direction of the beams 54A and 54B. The small beam 201 is installed between the floor receiving beam 54A and the floor receiving beam 54B so as to be parallel to the floor receiving beams 54C and 54D at a position where the hanging bundle 56 is fixed. The small beam 201 has the same cross section as the floor receiving beams 54A, 54B, 54C, 54D. In the height direction, the small beam 201 has an upper surface that coincides with the upper surfaces of the floor receiving beams 54A, 54B, 54C, and 54D, and a lower surface that coincides with the lower surfaces of the floor receiving beams 54A, 54B, 54C, and 54D. Be placed.

小梁201の長手方向の端部は、床受け梁54A,54Bの手前まで延びている。小梁201の端部と床受け梁54A,54Bとは、L字状の固定金具204を介して連結されている。この固定金具204が、小梁201と床受け梁54A,54Bとの連結部203を構成する。この固定金具204、すなわち連結部203の直上となる位置には、吊束56が配置されるような位置関係となる。これにより、小梁201に作用する荷重が直ちに連結部203を介して吊束56へ伝達され、当該吊束56を介して上方の梁30に伝達される。   The end of the small beam 201 in the longitudinal direction extends to the front of the floor receiving beams 54A and 54B. The end of the small beam 201 and the floor receiving beams 54A and 54B are connected via an L-shaped fixing bracket 204. The fixing bracket 204 constitutes a connecting portion 203 between the small beam 201 and the floor receiving beams 54A and 54B. At the position immediately above the fixing bracket 204, that is, the connecting portion 203, the hanging bundle 56 is disposed. As a result, the load acting on the small beam 201 is immediately transmitted to the suspended bundle 56 via the connecting portion 203, and is transmitted to the upper beam 30 via the suspended bundle 56.

小梁201の長手方向の略中央位置には、タイバー202が設けられる。タイバー202は、一の小梁201と、隣の小梁201との間に架設される。また、タイバー202は、小梁201と床受け梁54Cとの間にも架設され、小梁201と床受け梁54Dとの間にも架設される。タイバー202は、床受け梁54A,54Bと平行となるように架設される。タイバー202は、小梁201や床受け梁54C,54Dの下フランジの上面に固定される。   A tie bar 202 is provided at a substantially central position in the longitudinal direction of the small beam 201. The tie bar 202 is constructed between one small beam 201 and the adjacent small beam 201. The tie bar 202 is also installed between the small beam 201 and the floor receiving beam 54C, and is also installed between the small beam 201 and the floor receiving beam 54D. The tie bar 202 is constructed so as to be parallel to the floor receiving beams 54A and 54B. The tie bar 202 is fixed to the upper surface of the lower flange of the small beam 201 and the floor receiving beams 54C and 54D.

なお、ここでは、小梁201が二本設けられた例について説明しているが、特に本数は限定されず、更に増やしてもよい。吊束56も小梁201にあわせて増やす。   In addition, although the example provided with the two small beams 201 is demonstrated here, the number in particular is not limited and may increase further. The hanging bundle 56 is also increased in accordance with the small beam 201.

小梁201の側部には、床パネル41の側縁部41cを受けるための床受け部材252が設けられている。床受け部材252は、床受け部材52と同趣旨の構成を有しており、床パネル41の側縁部41cを受けるアングル部263と、アングル部263を支持して小梁201に固定される支持部264と、を有している。一の床パネル41の側縁部41cと、隣の床パネル41の側縁部41cとの間には、モルタルが充填されることによりモルタル部46が形成される。ここのモルタル部46は、小梁201の上面を覆うように形成される。   A floor receiving member 252 for receiving the side edge portion 41 c of the floor panel 41 is provided on the side portion of the small beam 201. The floor receiving member 252 has the same concept as the floor receiving member 52, and is fixed to the small beam 201 while supporting the angle portion 263 that receives the side edge portion 41 c of the floor panel 41 and the angle portion 263. And a support portion 264. A mortar portion 46 is formed between the side edge portion 41c of one floor panel 41 and the side edge portion 41c of the adjacent floor panel 41 by being filled with mortar. The mortar portion 46 is formed so as to cover the upper surface of the small beam 201.

以上によって、変形例に係る床構造200によれば、床受け部50の剛性を強化することができる。すなわち、床受け部50は、吊束56を介して梁30に垂下されている状態であり、剛床の床部40に過大な水平力又は鉛直力が導入された場合に、想定以上に当該剛床に水平方向又は鉛直方向の振動を許容してしまう可能性がある。従って、床受け部50の一方側と他方側で吊束56同士が対向するような位置関係とし、当該対向させた位置間で小梁201を架設することによって、一方側の梁30〜床受け部50の一方側の吊束56〜床受け部50の一方側の床受け梁54A〜小梁201〜床受け部50の他方側の床受け梁54B〜床受け部50の他方側の吊束56〜他方側の梁30、までの一体性が高まる。その結果、剛性が高められ、床下げ部の耐振動性を高めることができる。   As described above, according to the floor structure 200 according to the modification, the rigidity of the floor receiving portion 50 can be enhanced. That is, the floor receiving portion 50 is suspended from the beam 30 via the hanging bundle 56, and when an excessive horizontal force or vertical force is introduced into the floor portion 40 of the rigid floor, the floor receiving portion 50 is more than expected. There is a possibility of allowing horizontal or vertical vibrations to the hard floor. Therefore, by setting a positional relationship such that the suspended bundles 56 face each other on one side and the other side of the floor receiving portion 50, and constructing the small beam 201 between the facing positions, the beam 30 to the floor receiving on one side. Suspension bundle 56 on one side of part 50-Floor receiving beam 54A on one side of floor receiving part 50-Floor receiving beam 54B on the other side of floor receiving part 50-Hanging bundle on the other side of floor receiving part 50 The integrity from 56 to the beam 30 on the other side is increased. As a result, the rigidity is increased and the vibration resistance of the floor-lowering portion can be increased.

また、変形例に係る床構造200において、小梁201は、一対の床受け梁54A,54B間に複数設けられており、隣り合う小梁201の間には、タイバー202が架設されている。これにより、小梁201と直交する方向の剛性も高められ、床下げ部の耐振動性を更に向上させることができる。   In the floor structure 200 according to the modification, a plurality of small beams 201 are provided between a pair of floor receiving beams 54A and 54B, and a tie bar 202 is installed between adjacent small beams 201. Thereby, the rigidity of the direction orthogonal to the small beam 201 is also improved, and the vibration resistance of the floor-lowering portion can be further improved.

図10に示すような変形例に係る床構造300を採用してもよい。この床構造300は、柱320に端部が連結される大梁330間に、一対の小梁340が架設される。更に、一対の小梁340間には、一対の小梁350が架設される。この床構造300では、一対の小梁340と、一対の小梁350とで囲まれる空間SPに、床下げ部(例えば、前述したような床部40や床受け部50の構造)が設けられる。このように、床受け部を支持する梁(ここでは小梁340,350)が直接的に柱320に接合されていなくとも、前述の床構造100,200と同様の作用効果を得ることができる。   You may employ | adopt the floor structure 300 which concerns on a modification as shown in FIG. In the floor structure 300, a pair of small beams 340 are installed between the large beams 330 whose ends are connected to the columns 320. Further, a pair of small beams 350 is installed between the pair of small beams 340. In the floor structure 300, a floor-lowering portion (for example, the structure of the floor portion 40 or the floor receiving portion 50 as described above) is provided in a space SP surrounded by the pair of small beams 340 and the pair of small beams 350. . As described above, even if the beams (here, the small beams 340 and 350) that support the floor receiving portion are not directly joined to the column 320, the same operational effects as those of the above-described floor structures 100 and 200 can be obtained. .

また、例えば、床受け部50が受ける床部40の高さは、図4〜図6、図8,9で例示されているものに限られず、一般床部PF1と異なる高さであれば、梁30の天端30aよりも下方におけるどの位置で受けてもよい。また、床受け部は、梁30からのみ立ち上がって床部40を梁30の天端30aよりも上方で受けてもよい。例えば、床部40の側縁部を受けることのできる部材を有する金具を梁30から上方に立ち上がるように固定し、当該金具で梁30の天端30aより高い位置で床部40を受ける。このような構成において、金具は梁30にのみ支持され、柱の中途部には支持されない。   Further, for example, the height of the floor 40 received by the floor receiver 50 is not limited to those illustrated in FIGS. 4 to 6, 8, and 9, and may be a height different from the general floor PF <b> 1. It may be received at any position below the top end 30a of the beam 30. Further, the floor receiving portion may rise only from the beam 30 and receive the floor portion 40 above the top end 30 a of the beam 30. For example, a metal fitting having a member capable of receiving the side edge of the floor 40 is fixed so as to rise upward from the beam 30, and the floor 40 is received at a position higher than the top end 30 a of the beam 30 with the metal fitting. In such a configuration, the metal fitting is supported only by the beam 30 and not by the middle part of the column.

また、床受け部50は、床受け梁、吊束、床受け部材を備えていたが、吊束を有さず、梁30の下に直接床受け梁を固定してもよい。また、少なくとも床受け部材が固定される床受け梁のみが設けられていればよく、例えば床受け梁54C,54Dを省略してもよい。また、床受け梁を用いることなく、床部40を支持するための金具が、梁30に固定されていてもよい。この場合も、当該金具は梁30にのみ支持され、柱の中途部には支持されない。また、梁30と床受け梁54A,54B,54C,54Dとは、上下方向から見て重なるように、幅方向にずれることなく配置されていたが、梁54A,54B,54C,54Dが、梁30に対して幅方向にずれるように配置されていてもよい。例えば、梁30よりも床部40側に迫り出し、上下方向から見て梁30と全く重ならないように梁54A,54B,54C,54Dを配置してもよい。上述の実施形態では、部品の共用化を図るため、床パネル41として一般床部PF2における床パネルと同じパネルを用いることができ、梁54A,54B,54C,54Dとして梁30や他の部分の梁と同じ梁部材を用いることができる例について説明したが、共用化を図らず、専用の部品を作製してもよい。   Further, although the floor receiving portion 50 includes the floor receiving beam, the suspended bundle, and the floor receiving member, the floor receiving beam may be directly fixed under the beam 30 without having the suspended bundle. Further, it is only necessary to provide at least a floor receiving beam to which the floor receiving member is fixed. For example, the floor receiving beams 54C and 54D may be omitted. In addition, a metal fitting for supporting the floor portion 40 may be fixed to the beam 30 without using the floor receiving beam. Also in this case, the metal fitting is supported only by the beam 30 and is not supported by the middle part of the column. Further, the beam 30 and the floor receiving beams 54A, 54B, 54C, 54D are arranged without being shifted in the width direction so as to overlap each other when viewed from above and below, but the beams 54A, 54B, 54C, 54D It may be arranged so as to be shifted in the width direction with respect to 30. For example, the beams 54 </ b> A, 54 </ b> B, 54 </ b> C, and 54 </ b> D may be arranged so as to protrude toward the floor 40 from the beam 30 and not overlap the beam 30 when viewed from above and below. In the above-described embodiment, in order to share the parts, the same panel as the floor panel in the general floor portion PF2 can be used as the floor panel 41, and the beam 30 and other parts can be used as the beams 54A, 54B, 54C, and 54D. Although an example in which the same beam member as that of the beam can be used has been described, a dedicated component may be manufactured without sharing.

また、図4〜図6、図8,9で示している柱梁の配置や間隔も一例に過ぎず、どのような柱梁構造に対しても本発明の床構造を適用することができる。例えば、対向し合う梁の間隔が大きい場合、途中でそれらの梁に平行な床受け梁を架け渡してもよい。例えば、床パネルが長辺方向に複数枚必要な場合に、床パネルの境界部分に床受け梁を架け渡すと共に、当該床受け梁に図7のような床受け部材を固定し、床パネルを途中で受けてもよい。   Further, the arrangement and interval of the column beams shown in FIGS. 4 to 6 and FIGS. 8 and 9 are merely examples, and the floor structure of the present invention can be applied to any column beam structure. For example, when the distance between the beams facing each other is large, floor receiving beams parallel to the beams may be bridged on the way. For example, when a plurality of floor panels are required in the long side direction, a floor receiving beam is bridged over the boundary portion of the floor panel, and a floor receiving member as shown in FIG. 7 is fixed to the floor receiving beam. You may receive it on the way.
