Description

本発明は、一対の躯体梁間に設けられる床フレームの設置構造に関する。   The present invention relates to a floor frame installation structure provided between a pair of frame beams.

従来、戸建て住宅等の施工は、最初に基礎の施工が行われ、その後に、梁柱等を設置する躯体工事、屋根や外壁パネル間の目地を埋める防水工事、界壁やユニットバス等を設置する躯体内部工事が行われ、最後に木工事や仕上げ工事が行われる。このような工程で進行する建物の施工では、効率化の観点から、各工事が別々の業者により行われることが多い。そのため、前工程の工事結果を変更する場合には、他の業者の協力が必要となり施工が非効率となるおそれがある。   Conventionally, the construction of detached houses, etc., has been carried out first, followed by frame construction for installing beam pillars, waterproof construction for filling joints between roofs and outer wall panels, border walls and unit baths, etc. The interior of the building will be done, and finally wood work and finishing work will be done. In the construction of a building that proceeds in such a process, each construction is often performed by a separate contractor from the viewpoint of efficiency. Therefore, when changing the construction result of the previous process, the cooperation of other contractors is required, and the construction may become inefficient.

例えば、浴室部（ユニットバス）の設置施工では、ユニットバスの設置位置によっては、躯体工事の結果を一部変更しなければユニットバスの設置が行えない場合がある。躯体工事の結果を一部変更する場合、再度の躯体工事とユニットバスの設置という２つの施工が必要となり、この場合、躯体工事を行う設置業者とユニットバスを設置する設置業者とが混在して作業を行うこととなる。すなわち、施工のみならず設置業者が混在することとなる。このことで、設置業者による施工が非効率になるという問題がある。かかる問題を解決すべく、例えば特許文献１には、ユニットフロアに固定された複数の小梁を大梁に着脱自在とした構成が開示されている。   For example, in the installation construction of a bathroom part (unit bath), depending on the installation position of the unit bath, the unit bath may not be installed unless the result of the frame construction is partially changed. To partially change the result of the frame construction, it is necessary to carry out two types of construction, the second frame construction and the installation of the unit bath. In this case, the installation contractor who installs the frame construction and the installation contractor who installs the unit bus are mixed. Work will be done. That is, not only construction but also installation contractors are mixed. As a result, there is a problem that the installation by the installer becomes inefficient. In order to solve such a problem, for example, Patent Document 1 discloses a configuration in which a plurality of small beams fixed to a unit floor are detachable from a large beam.

特開２００４−２７８２１０号公報JP 2004-278210 A

ユニットバスの施工は、躯体梁と該躯体梁に架設される床フレームが設置される躯体工事、及び、躯体工事後に行われる該躯体梁上への壁体の設置施工、の後に行われることが一般的である。ここで、躯体梁上に壁体が設置された後には、特許文献１に記載された構成をもってしても床フレームを取り外すことはできない。この場合、床フレームを残したままユニットバス設置作業を行うか、施工手順を見直す必要があり、施工性が悪化するという問題があった。   The construction of the unit bath may be carried out after the frame construction in which the frame beam and the floor frame constructed on the frame beam are installed, and the wall installation on the frame beam performed after the frame construction. It is common. Here, after the wall body is installed on the frame beam, the floor frame cannot be removed even with the configuration described in Patent Document 1. In this case, it is necessary to perform the unit bath installation work while leaving the floor frame or to review the construction procedure, and there is a problem that the workability deteriorates.

そこで、本願発明は、施工手順を改変することなく、躯体施工後にユニットバス等の後設置物を設置することができる床フレームの設置構造を提供することを目的とする。   Then, this invention aims at providing the installation structure of the floor frame which can install post-installation things, such as a unit bath, after a frame construction, without changing a construction procedure.

本発明に係る床フレームの設置構造は、対向して設けられた一対の躯体梁と、一対の躯体梁間に架設された床フレームと、一対の躯体梁のうち少なくとも一方の躯体梁上に設けられた壁体と、を備え、床フレームは、その壁体に近接する端部が、壁体の表面よりも一方の躯体梁から離間した位置で着脱自在に支持されていることを特徴とする。   The floor frame installation structure according to the present invention is provided on at least one of the pair of frame beams, a pair of frame beams provided opposite to each other, a floor frame provided between the pair of frame beams, and the pair of frame beams. The floor frame is characterized in that an end portion close to the wall body is detachably supported at a position farther from one frame beam than the surface of the wall body.

本発明によれば、壁体下の躯体梁から見て、その躯体梁に対して壁体の表面よりも該躯体梁から離間した位置に床フレームの端部が設けられることとなる。その結果、躯体梁上に壁体を設置した後であっても、該壁体によって床フレームの着脱が制限されることがない。すなわち、壁体の設置後にも床フレームを取り外すことができ、効率的に施工を行うことが可能となる。   According to the present invention, when viewed from the frame beam under the wall, the end of the floor frame is provided at a position farther from the frame beam than the surface of the wall with respect to the frame beam. As a result, even after the wall body has been installed on the frame beam, the wall body does not restrict the attachment / detachment of the floor frame. That is, the floor frame can be removed even after the wall body is installed, and the construction can be performed efficiently.

また、一方の躯体梁には、床フレームの端部を支持する受け具が設けられており、受け具は、壁体の表面よりも上記の一方の躯体梁から離間した内側の位置で床フレームの端部を着脱自在に支持していると好適である。これによれば、床フレームの端部を、受け具を介して、壁体の表面よりも躯体梁間の内側に位置づけた状態で確実に架設できる。   In addition, one of the frame beams is provided with a support for supporting the end of the floor frame, and the support frame is located at an inner position farther from the one frame beam than the surface of the wall. It is preferable that the end portion of this is detachably supported. According to this, the end portion of the floor frame can be reliably installed in a state where the end portion of the floor frame is positioned on the inner side between the frame beams rather than the surface of the wall body.

また、受け具は、壁体の下端部を支持する壁受け部と、該壁受け部から突設され、且つ床フレームの端部を支持するフレーム受け部と、を有し、壁受け部は、一方の躯体梁の側縁部よりも内側に突き出た部分を有していると好適である。受け具が壁受け部とフレーム受け部とを有していることで、床フレームのみならず壁体をも支持することができる。また、壁受け部が躯体梁の側縁部よりも該躯体梁と対向する躯体梁側に突き出た部分を含んでいることで、躯体梁の幅よりも大きい壁厚を有する壁体を支持することが可能となる。   The receiver includes a wall receiving portion that supports the lower end portion of the wall body, and a frame receiving portion that protrudes from the wall receiving portion and supports the end portion of the floor frame, and the wall receiving portion is It is preferable to have a portion protruding inward from the side edge of one of the frame beams. Since the receiving device has the wall receiving portion and the frame receiving portion, it is possible to support not only the floor frame but also the wall body. Further, the wall receiving portion includes a portion protruding to the side of the frame beam facing the frame beam from the side edge of the frame beam, thereby supporting a wall body having a wall thickness larger than the width of the frame beam. It becomes possible.

また、壁体の下方であって躯体梁の内側には、その内表面が壁体の表面に揃う補助壁部材が設けられ、受け具には、一方の躯体梁の上端部よりも上方で補助壁部材の上端部を収容する補助壁収容部が凹設されていることが好適である。躯体梁と隣り合う位置に設けられた補助壁部材の上端部が、該躯体梁の上端部よりも上方に位置することで、補助壁部材の上端部と躯体梁の上端部との間で段差が生じることとなる。このことで、躯体梁の側方から見ると躯体梁の上端部が補助壁部材により覆われることとなり、補助壁部材により躯体梁側への断熱性、防音性が高められ、躯体梁及び壁体を介して隣り合う室同士が互いの影響を受け難いものとできる。   In addition, an auxiliary wall member is provided below the wall body and inside the frame beam so that the inner surface thereof is aligned with the surface of the wall body, and the support is provided above the upper end of one frame beam. It is preferable that the auxiliary wall housing portion for housing the upper end portion of the wall member is recessed. The upper end of the auxiliary wall member provided at a position adjacent to the frame beam is located above the upper end of the frame beam, so that a step is formed between the upper end of the auxiliary wall member and the upper end of the frame beam. Will occur. Thus, when viewed from the side of the frame beam, the upper end of the frame beam is covered with the auxiliary wall member, and the auxiliary wall member improves the heat insulation and soundproofing to the frame beam side, and the frame beam and the wall body The rooms adjacent to each other can be hardly affected by each other.

本発明によれば、壁体の設置後にも床フレームを取り外すことができ、効率的に施工が行える床フレームの設置構造を提供することができる。   ADVANTAGE OF THE INVENTION According to this invention, a floor frame can be removed even after installation of a wall body, and the installation structure of the floor frame which can be constructed efficiently can be provided.

Further, the inner surface of the upper standing piece 22t, in other words, the surface on the steel beam 3b side facing the steel beam 3a is aligned with the surface 4x of the wall 4. Further, the upper standing pieces 22t and the upper ends of the reinforcing ribs 22c, that is, the upper ends of the wall receiving portions 22a are aligned with the floor 41. As a result, the left and right sides (the wall receiving portion 22a side and the floor material 41 side) of the wall body 4 provided on the wall receiving portion 22a and the floor material 41 are aligned, and members are reduced. In addition, the mortar 13 is filled in the space | interval formed between the upper flange 31, the wall receiving part 22a, and the edge part of the flooring 41, and the steel beam 3a, the wall receiving part 22a, the clip material 53, and the flooring 41 Are integrally fixed.

モルタル受け部２２ｂの上段水平片２２ｓは、鉄骨梁３ａの側縁部３４ａよりも内側、言い換えれば、鉄骨梁３ａに対向する鉄骨梁３ｂ側に突き出している。また、下段起立片２２ｒと上段水平片２２ｓとが屈曲して連絡することでモルタル受け部２２ｂの内側には凹部が形成され、つまり凹設された構造となっている。つまり、下段起立片２２ｒと上段水平片２２ｓとによって補助壁部材５を収容する補助壁収容部２２ｚが形成される。   The upper horizontal piece 22s of the mortar receiving portion 22b protrudes on the inner side of the side edge portion 34a of the steel beam 3a, in other words, on the side of the steel beam 3b facing the steel beam 3a. Further, the lower standing piece 22r and the upper horizontal piece 22s are bent and connected to each other, so that a concave portion is formed inside the mortar receiving portion 22b, that is, a structure in which the concave portion is provided. That is, the auxiliary wall accommodating portion 22z that accommodates the auxiliary wall member 5 is formed by the lower standing piece 22r and the upper horizontal piece 22s.

補助壁部材５は、矩形のＡＬＣパネルからなり、落とし込み部２の側面に沿って短手が縦、長手が横になるように配置される。補助壁部材５は、下端がパネル受け片６３の上段水平片６６上に載置され、上段起立片６７及び平板８に挟まれるようにして支えられる。補助壁部材５の内側の表面（内表面）５ｘと壁体４の表面４ｘとは、完全に同一の平面上（面一）ではないものの、略揃った状態となるように配置されている。   The auxiliary wall member 5 is composed of a rectangular ALC panel, and is arranged along the side surface of the drop-in portion 2 such that the short side is vertical and the long side is horizontal. The auxiliary wall member 5 is supported such that its lower end is placed on the upper horizontal piece 66 of the panel receiving piece 63 and is sandwiched between the upper standing piece 67 and the flat plate 8. Although the inner surface (inner surface) 5x of the auxiliary wall member 5 and the surface 4x of the wall body 4 are not completely on the same plane (the same surface), they are arranged so as to be substantially aligned.

補助壁部材５の上端部５１は、補助壁収容部２２ｚ内に収まるように設置され、壁受け部２２ａの下段起立片２２ｒに当接している。下段起立片２２ｒには、断面Ｕ字状に形成されたピース状のクリップ材５３が嵌め込まれる切欠きが長手方向に所定間隔で形成されており、補助壁部材５の上端部５１は、クリップ材５３と下段起立片２２ｒの間に挟持されている。   The upper end portion 51 of the auxiliary wall member 5 is installed so as to be accommodated in the auxiliary wall housing portion 22z, and is in contact with the lower standing piece 22r of the wall receiving portion 22a. The lower standing piece 22r is formed with notches into which piece-like clip materials 53 formed in a U-shaped cross section are fitted at predetermined intervals in the longitudinal direction, and the upper end portion 51 of the auxiliary wall member 5 is formed of a clip material. 53 and the lower erected piece 22r.

壁受け部２２ａには、床フレーム１０の端部１０ｃを支持する断面略Ｌ字状のフレーム受け部２１ａが固定されている。フレーム受け部２１ａは、壁受け部２２ａの上段起立片２２ｔに溶接される固定部２１ｙと、固定部２１ｙから内側、言い換えれば対向する鉄骨梁３ｂ側に突き出して床フレーム１０の端部１０ｃを支えるフレーム載置部２１ｘとを備えている。   A frame receiving portion 21a having a substantially L-shaped cross section for supporting the end portion 10c of the floor frame 10 is fixed to the wall receiving portion 22a. The frame receiving portion 21a supports the end portion 10c of the floor frame 10 by protruding from the fixing portion 21y to the inner side, in other words, the opposite steel beam 3b side, and the fixing portion 21y welded to the upper standing piece 22t of the wall receiving portion 22a. And a frame placing portion 21x.

壁受け部２２ａの上段起立片２２ｔは壁体４の表面４ｘに揃っており、従って、上段起立片２２ｔから内側に突き出したフレーム受け部２１ａは、鉄骨梁３ａに対して壁体４の表面４ｘよりも離間した内側の位置に設けられている。その結果、フレーム受け部２１ａに支持された床フレーム１０についても、鉄骨梁３ａに対して壁体４の表面４ｘよりも内側に離間した位置に設けられている。   The upper standing piece 22t of the wall receiving portion 22a is aligned with the surface 4x of the wall body 4. Therefore, the frame receiving portion 21a protruding inward from the upper standing piece 22t has the surface 4x of the wall body 4 with respect to the steel beam 3a. It is provided in the inner position farther away. As a result, the floor frame 10 supported by the frame receiving portion 21a is also provided at a position spaced inward from the surface 4x of the wall 4 with respect to the steel beam 3a.

床フレーム１０は、端部１０ｃがフレーム受け部２１ａのフレーム載置部２１ｘに載置された状態でボルト２５とナット２６とにより締結されており、締結を解くことでフレーム受け部２１ａから取り外すことができる。すなわち、床フレーム１０はフレーム受け部２１ａに着脱自在に支持されている。なお、ボルト２５とナット２６とによる締結は、ユニットバス空間Ａの設置施工完了後に行われことが好ましい。   The floor frame 10 is fastened by bolts 25 and nuts 26 with the end 10c placed on the frame placing part 21x of the frame receiving part 21a, and is removed from the frame receiving part 21a by releasing the fastening. Can do. That is, the floor frame 10 is detachably supported by the frame receiving portion 21a. The fastening by the bolt 25 and the nut 26 is preferably performed after the installation work of the unit bath space A is completed.

界壁である鉄骨梁３ａ上の壁体４は、遮音性及び断熱性の向上を図るための種々の部材により構成されている。すなわち、壁体４は中央部近辺にロックウール等を用いた断熱材８１が設けられている。また、断熱材８１の周囲を覆うようにして、遮音シートや石膏ボードが設けられ、遮音性の向上が図られている。   The wall body 4 on the steel beam 3a which is a boundary wall is composed of various members for improving sound insulation and heat insulation. That is, the wall body 4 is provided with a heat insulating material 81 using rock wool or the like in the vicinity of the center. In addition, a sound insulation sheet and a gypsum board are provided so as to cover the periphery of the heat insulating material 81, so that the sound insulation is improved.

図１、及び図２に示されるように、鉄骨梁３ｂ側の受け具２０ｂの実質的な機能は、鉄骨梁３ａ側の受け具２０ａと同様であるが、構造や形状が一部異なる。具体的には、受け具２０ｂは壁受け部２３ａとフレーム受け部２４ａとを備えており、壁受け部２３ａは、断面略Ｌ字状で鉄骨梁３ｂの上フランジ３１に取り付けられるモルタル受け部２３ｂと、補強リブ２３ｃとを備えている。モルタル受け部２３ｂは、下段水平片２３ｑが上フランジ３１にボルト締結されている。なお、壁受け部２３ａは、鉄骨梁３ａ側の壁受け部２２ａと異なり、対向する鉄骨梁３ａ側に突出した部分を有していない。   As shown in FIGS. 1 and 2, the substantial function of the steel beam 3b-side support 20b is the same as that of the steel beam 3a-side support 20a, but the structure and shape are partially different. Specifically, the receiving device 20b includes a wall receiving portion 23a and a frame receiving portion 24a. The wall receiving portion 23a has a substantially L-shaped cross section and is attached to the upper flange 31 of the steel beam 3b. And a reinforcing rib 23c. As for the mortar receiving part 23b, the lower horizontal piece 23q is bolted to the upper flange 31. In addition, the wall receiving part 23a is different from the wall receiving part 22a on the steel beam 3a side, and does not have a portion protruding to the opposite steel beam 3a side.

フレーム受け部２４ａは、壁受け部２３ａに溶接される固定部２４ｙと、固定部２４ｙから内側、言い換えれば対向する鉄骨梁３ａ側に突き出して床フレーム１０の端部１０ｄを支えるフレーム載置部２４ｘとを備えている。フレーム載置部２４ｘは、鉄骨梁３ａ側のフレーム載置部２１ｘに比べて対向する鉄骨梁３ａ側への突き出し長さが長くなっている。その結果、受け具２０ｂが床フレーム１０の端部１０ｄを支持する箇所は、鉄骨梁３ａに対して壁体４の表面４ｘよりも内側に離間した位置に設けられている。なお、壁受け部２３ａに対してフレーム受け部２４ａが突き出すことで受け具２０ｂには凹設された部位が存在することになり、この凹設された部位が補助壁部材５を収容する補助壁収容部となる。   The frame receiving portion 24a includes a fixing portion 24y welded to the wall receiving portion 23a, and a frame placement portion 24x that protrudes inward from the fixing portion 24y, in other words, the opposite steel beam 3a side and supports the end portion 10d of the floor frame 10. And. The frame mounting portion 24x has a longer protruding length toward the opposing steel beam 3a than the frame mounting portion 21x on the steel beam 3a side. As a result, the place where the receiving member 20b supports the end portion 10d of the floor frame 10 is provided at a position spaced inward from the surface 4x of the wall body 4 with respect to the steel beam 3a. The frame receiving portion 24a protrudes from the wall receiving portion 23a, so that there is a recessed portion in the receiving device 20b. The recessed portion accommodates the auxiliary wall member 5. It becomes a housing part.

次に、図１〜図３を用いて、ユニットバス施工までの一連の工程について説明する。建物の躯体を施工する工程では、柱と梁が組まれ、床パネルが敷設されると共に、外壁パネルが設置される。本実施形態に係る浴室部は、落とし込み部２に床材１１が敷設され、洗面所空間Ｂとなる床材１１の上方に床フレーム１０が設置される。以下、詳細に説明する。   Next, a series of steps up to the construction of the unit bath will be described with reference to FIGS. In the process of constructing the building frame, pillars and beams are assembled, floor panels are laid, and outer wall panels are installed. In the bathroom part according to the present embodiment, a flooring 11 is laid on the dropping part 2, and a floor frame 10 is installed above the flooring 11 serving as a washroom space B. Details will be described below.

浴室部を施工する際には、鉄骨梁３ａ，３ｂにパネル受け金物６を取り付け、落とし込み部２に床材１１を設置する。次に、落とし込み部２の周囲に沿って補助壁部材５を設置し、床フレーム１０を取り付けるための受け具２０ａ，２０ｂを鉄骨梁３ａ，３ｂに取り付ける。その後、受け具２０ａ，２０ｂに床フレーム１０を載置し、必要に応じてボルト締結などで仮止めする。その後、クリップ材５３を差し込み、補助壁部材５を固定する。   When constructing the bathroom part, the panel support 6 is attached to the steel beams 3 a and 3 b, and the flooring 11 is installed in the dropping part 2. Next, the auxiliary wall member 5 is installed along the periphery of the dropping part 2, and the receiving tools 20a and 20b for attaching the floor frame 10 are attached to the steel beams 3a and 3b. Thereafter, the floor frame 10 is placed on the receivers 20a and 20b, and temporarily fixed by bolt fastening or the like as necessary. Thereafter, the clip material 53 is inserted, and the auxiliary wall member 5 is fixed.

床フレーム１０を設置した後、受け具２０ａ，２０ｂの壁受け部２２ａ，２３ａ及び床材４１上の隙間をモルタル１３で埋め、壁体４を立設する界壁施工を行う。界壁施工に際しては、最初に、断面コ字状のランナが上下に対向するように設置され、該ランナ間にスタッドが設置される。そして、スタッドを固定しつつ下地材が組み上げられ、当該下地材に石膏ボードが敷設され界壁となる壁体４を形成する。   After the floor frame 10 has been installed, the gaps on the wall receiving portions 22a and 23a and the floor material 41 of the receiving devices 20a and 20b are filled with the mortar 13, and the boundary wall construction for standing the wall body 4 is performed. When constructing the boundary wall, first, runners having a U-shaped cross section are installed so as to face each other vertically, and studs are installed between the runners. Then, the base material is assembled while fixing the studs, and a gypsum board is laid on the base material to form a wall body 4 serving as a boundary wall.

壁体施工の完了後、ユニットバス施工を行う。ユニットバス空間Ａに隣接する洗面所空間Ｂに床フレーム１０が設置されたままだとユニットバスや配管等の設置の際に邪魔になるので、まずは、床フレーム１０を取り外す。この際、床フレーム１０はフレーム受け部２１ａ，２４ａに設置されているだけなので簡単に取り外しできる。   After completing the wall construction, the unit bath will be constructed. If the floor frame 10 is left installed in the washroom space B adjacent to the unit bath space A, the floor frame 10 is first removed because it interferes with the installation of the unit bath and piping. At this time, the floor frame 10 is simply installed on the frame receiving portions 21a and 24a, so that it can be easily removed.

その後、ユニットバス空間Ａにユニットバスを設置し、合わせて配管施工を行う。最後に、床フレーム１０を再度架設し、床フレーム１０をボルト締結によってフレーム受け部２１ａ，２４ａに固定する。   Thereafter, a unit bus is installed in the unit bath space A, and piping work is performed together. Finally, the floor frame 10 is installed again, and the floor frame 10 is fixed to the frame receiving portions 21a and 24a by bolt fastening.

上述した床フレーム１０の設置構造１では、壁体４下の鉄骨梁３ａから見て、壁体４の表面４ｘよりも鉄骨梁３ａから離間した位置に床フレーム１０の端部１０ｃが設けられることとなる。また、壁体４下の鉄骨梁３ｂから見て、壁体４の表面４ｘよりも鉄骨梁３ｂから離間した位置に床フレーム１０の端部１０ｄが設けられることとなる。その結果、鉄骨梁３ａ，３ｂ上に界壁となる壁体４を設置した後に、隣接するユニットバス空間Ａにユニットバスや配管を設置する必要などが生じた場合にも、施工の邪魔になる床フレーム１０の着脱が制限されることはない。すなわち、壁体４の設置後にも床フレーム１０を取り外すことができ、効率的な施工が実現可能となる。   In the installation structure 1 of the floor frame 10 described above, the end portion 10c of the floor frame 10 is provided at a position farther from the steel beam 3a than the surface 4x of the wall body 4 when viewed from the steel beam 3a below the wall body 4. It becomes. Further, when viewed from the steel beam 3b below the wall body 4, the end portion 10d of the floor frame 10 is provided at a position farther from the steel beam 3b than the surface 4x of the wall body 4. As a result, even if it becomes necessary to install a unit bath or piping in the adjacent unit bath space A after installing the wall body 4 as the boundary wall on the steel beams 3a and 3b, it also obstructs the construction. The attachment / detachment of the floor frame 10 is not limited. That is, the floor frame 10 can be removed even after the wall body 4 is installed, and efficient construction can be realized.

また、鉄骨梁３ａには、床フレーム１０の端部１０ｃを、壁体４の表面４ｘよりも、鉄骨梁３ａから離間した内側の位置で着脱自在に支持する受け具２０ａが設けられており、同様に、鉄骨梁３ｂには、受け具２０ｂが設けられている。したがって、床フレーム１０を、その端部１０ｃ，１０ｄを壁体４の表面４ｘよりも鉄骨梁３ａ，３ｂ間の内側に位置づけた状態で、受け具２０ａを介して鉄骨梁３ａに確実に架設できる。   In addition, the steel beam 3a is provided with a support 20a that detachably supports the end portion 10c of the floor frame 10 at an inner position farther from the steel beam 3a than the surface 4x of the wall body 4, Similarly, the steel beam 3b is provided with a receiving tool 20b. Therefore, the floor frame 10 can be reliably installed on the steel beam 3a via the support 20a in a state where the end portions 10c and 10d are positioned inside the steel beam 3a and 3b with respect to the surface 4x of the wall 4. .

また、受け具２０ａは、壁体４の下端部を支持する壁受け部２２ａと、壁受け部２２ａから突設され、且つ床フレーム１０の端部１０ｃを支持するフレーム受け部２１ａとを有し、同様に、受け具２０ｂは、壁受け部２３ａと、フレーム受け部２３ａとを有している。その結果、受け具２０ａ，２０ｂにより、床フレーム１０だけでなく壁体４も支持できる。   The receiving device 20a includes a wall receiving portion 22a that supports the lower end portion of the wall body 4, and a frame receiving portion 21a that protrudes from the wall receiving portion 22a and supports the end portion 10c of the floor frame 10. Similarly, the receiving tool 20b includes a wall receiving portion 23a and a frame receiving portion 23a. As a result, not only the floor frame 10 but also the wall body 4 can be supported by the receivers 20a and 20b.

更に、壁受け部２２ａが、壁体４下の鉄骨梁３ａの側縁部３４ａよりも鉄骨梁３ａの対向側に突き出た部分を含んでいることで、鉄骨梁３の梁芯と壁体４の壁芯とを一致させ、鉄骨梁３ａの幅よりも大きい壁厚を有する壁体４を支持することが可能となる。   Furthermore, the wall receiving portion 22a includes a portion protruding to the opposite side of the steel beam 3a with respect to the side edge 34a of the steel beam 3a below the wall body 4, so that the beam core of the steel beam 3 and the wall body 4 are included. It is possible to support the wall body 4 having a wall thickness larger than the width of the steel beam 3a.

また、壁体４の下方であって鉄骨梁３ａ，３ｂの内側には、その内表面５ｘが壁体４の表面４ｘに略面一つまり揃った状態となる補助壁部材５が設けられ、受け具２０ａには鉄骨梁３ａの上フランジ３１よりも上方で補助壁部材５の上端部５１を収容する補助壁収容部２２ｚが凹設されており、受け具２０ｂには鉄骨梁３ｂの上フランジ３１よりも上方で補助壁部材５の上端部５１を収容する補助壁収容部２２ｚが凹設されている。その結果、補助壁部材５の上端部５１と鉄骨梁３ａ，３ｂの上フランジ３１との間で段差が生じることとなる。つまり、鉄骨梁３ａ，３ｂの側方から見た場合に、鉄骨梁３ａ，３ｂの上フランジ３１と受け具２０ａ，２０ｂの下段水平片２２ｑ，２３ｑとの継ぎ目（界面）が補助壁部材５により覆われることとなる。補助壁部材５により鉄骨梁３ａ，３ｂ側への断熱性、防音性が高められ、鉄骨梁３ａ，３ｂ及び壁体４を介して隣り合う室同士が互いの影響を受け難いものとできる。   An auxiliary wall member 5 is provided below the wall body 4 and inside the steel beams 3a and 3b so that the inner surface 5x thereof is substantially flush with the surface 4x of the wall body 4, that is, aligned. Auxiliary wall accommodating portion 22z for accommodating the upper end portion 51 of the auxiliary wall member 5 is recessed in the tool 20a above the upper flange 31 of the steel beam 3a, and the upper flange 31 of the steel beam 3b is provided in the receiver 20b. An auxiliary wall accommodating portion 22z that accommodates the upper end portion 51 of the auxiliary wall member 5 is recessed above the upper portion. As a result, a step is generated between the upper end portion 51 of the auxiliary wall member 5 and the upper flange 31 of the steel beams 3a and 3b. That is, when viewed from the side of the steel beams 3a and 3b, the joint (interface) between the upper flange 31 of the steel beams 3a and 3b and the lower horizontal pieces 22q and 23q of the receivers 20a and 20b is formed by the auxiliary wall member 5. It will be covered. The auxiliary wall member 5 enhances the heat insulation and soundproofing properties toward the steel beams 3a and 3b, so that the adjacent chambers are less likely to be affected by each other via the steel beams 3a and 3b and the wall body 4.

[第２実施形態]
次に、図４を参照して、第２実施形態に係る床フレーム１０の設置構造１Ａについて説明する。なお、第２実施形態では、第１実施形態に係る床フレーム１０の設置構造１と実質的に同一の部材や要素を備えているので、以下の説明では、第１実施形態との相違点を中心に説明し、同一の部材や要素には同一の符号を付して重複する説明は省略する。 [Second Embodiment]
Next, with reference to FIG. 4, the installation structure 1A of the floor frame 10 which concerns on 2nd Embodiment is demonstrated. In addition, in 2nd Embodiment, since the substantially same member and element as the installation structure 1 of the floor frame 10 which concern on 1st Embodiment are provided, in the following description, a difference with 1st Embodiment is provided. It demonstrates centering, the same code | symbol is attached | subjected to the same member and element, and the overlapping description is abbreviate | omitted.

図４に示されるように、床フレーム１０の設置構造１Ａは、建物の１階に設けられるユニットバス（図示せず）の施工において、ユニットバス空間に隣接する洗面所空間に設けられる床フレーム１０の設置構造１Ａである。   As shown in FIG. 4, the floor frame 10 installation structure 1 </ b> A is a floor frame 10 provided in a washroom space adjacent to a unit bath space in the construction of a unit bath (not shown) provided on the first floor of a building. This is an installation structure 1A.

第１実施形態とは異なり、第２実施形態では、躯体梁として鉄骨梁ではなく、鉄筋コンクリート構造の基礎梁３ｘを利用する。   Unlike the first embodiment, the second embodiment uses a foundation beam 3x having a reinforced concrete structure instead of a steel beam as a frame beam.

基礎梁３ｘ上には、床材４１と受け具８５が固定されている。受け具８５は、基礎梁３ｘの上端に設置されたプレート状のフレーム受け部８５ａと、フレーム受け部８５ａの途中に立設された壁受け部８５ｂとを備えている。フレーム受け部８５ａは、壁受け部８５ｂよりも先端側で僅かに下方にオフセットしており、更にオフセットした先が壁体４の表面４ｘよりも基礎梁３ｘから対向する他の基礎梁（図示せず）側、つまり内側に突き出している。この先端側に、床フレーム１０の端部１０ｘが載置され、着脱自在にボルト締結される。壁受け部８５ｂ、床材４１、及び基礎梁３ｘの上端で形成される隙間には、モルタル１４が充填され一体的に固定されている。   On the foundation beam 3x, a flooring 41 and a receiving tool 85 are fixed. The support 85 includes a plate-shaped frame receiving portion 85a installed at the upper end of the foundation beam 3x, and a wall receiving portion 85b erected in the middle of the frame receiving portion 85a. The frame receiving portion 85 a is slightly offset downward on the tip side from the wall receiving portion 85 b, and further the other end of the foundation beam (not shown) whose offset tip is opposed to the foundation beam 3 x rather than the surface 4 x of the wall body 4. Z) and protrudes inward. An end portion 10x of the floor frame 10 is placed on the front end side and is detachably bolted. The gap formed by the upper ends of the wall receiving portion 85b, the floor material 41, and the foundation beam 3x is filled with mortar 14 and fixed integrally.

本実施形態における床フレーム１０の設置構造１Ａでは、壁体４の表面４ｘよりも床材４１から内側に離間した位置で、床フレーム１０がフレーム受け部１２１に支持されている。その結果、壁体４を設置した後であっても、壁体４によって床フレーム１０の着脱が制限されることがない。すなわち、本実施形態のように１階に設けられるユニットバスの施工においても、効率的な施工が実現できる。   In the installation structure 1A of the floor frame 10 in the present embodiment, the floor frame 10 is supported by the frame receiving portion 121 at a position spaced inward from the floor material 41 with respect to the surface 4x of the wall body 4. As a result, even after the wall body 4 is installed, the wall body 4 does not restrict the attachment / detachment of the floor frame 10. That is, efficient construction can be realized also in the construction of the unit bus provided on the first floor as in the present embodiment.

以上、本発明について各実施形態に基づいて説明したが、本発明は、以上の各実施形態のみに限定されない。例えば、第１実施形態では、対向して設けられた梁３ａ，３ｂの双方の上方に壁体４が設けられているとして説明したが、本発明に係る床フレームの設置構造では、対向して設けられた躯体梁の一方の躯体梁上方にのみ壁体が設けられるものであってもよい。また、一方の躯体梁上にのみ壁体、他方の躯体梁上には壁体を有しない間取り構造の場合、一方の躯体梁側にのみ本願発明の構成を採用し、他方の躯体梁には公知の方法で床フレームを着脱自在に支持する構成を採用することができる。   As mentioned above, although this invention was demonstrated based on each embodiment, this invention is not limited only to the above each embodiment. For example, in the first embodiment, it has been described that the wall body 4 is provided above both the beams 3a and 3b provided to face each other. However, in the floor frame installation structure according to the present invention, the walls 3a and 3b face each other. The wall body may be provided only above one of the frame beams provided. In addition, in the case of a floor plan structure that does not have a wall on one frame beam and a wall on the other frame beam, the configuration of the present invention is adopted only on one frame beam side, and the other frame beam has A configuration in which the floor frame is detachably supported by a known method can be employed.
