Description

本発明は、天井裏空間に設けられる天井下地構造、当該天井下地構造の施工方法及び当該天井下地構造が備える耐震接続部材に関するものである。 The present invention relates to a ceiling base structure provided in a space behind the ceiling, a method of constructing the ceiling base structure, and a seismic connection member provided in the ceiling base structure.

建築構造物の居室の天井を構成する天井パネルの裏側、いわゆる天井裏空間には、例えば空調用ダクト、空調用配管、ガス配管や電装配線などを含む種々の設備配管等が配設されている。これらの設備配管等は、建築構造物の天井スラブから吊下するように配設される場合がある。 On the back side of the ceiling panel that constitutes the ceiling of the living room of the building structure, the so-called ceiling space, for example, various equipment piping including air conditioning ducts, air conditioning piping, gas piping, electrical wiring, etc. are arranged. .. These equipment pipes and the like may be arranged so as to be suspended from the ceiling slab of the building structure.

具体的には、例えば特許文献1には、懸垂物体である空調用ダクトを常磁性の固定物体に吊り下げ支持することが開示されている。特許文献1に記載の吊り下げ支持方法によれば、吊り金具を磁力によって前記固定物体に固着し、当該吊り金具にワイヤ及びバンドを用いて空調ダクトを吊り下げ支持する。 Specifically, for example, Patent Document 1 discloses that an air conditioning duct, which is a suspended object, is suspended and supported by a paramagnetic fixed object. According to the hanging support method described in Patent Document 1, the hanging metal fitting is fixed to the fixed object by magnetic force, and the air conditioning duct is suspended and supported by using a wire and a band on the hanging metal fitting.

また特許文献2には、天井等に所定間隔で設けられたフックに掛けられた吊り紐と、廃気用ダクトに固定された掛け金具とをつなぐことで、ダクト装置の廃気用ダクトを天井等から吊下固定することが開示されている。 Further, in Patent Document 2, the waste air duct of the duct device is connected to the ceiling by connecting the hanging straps hung on the hooks provided on the ceiling or the like at predetermined intervals and the hanging metal fittings fixed to the waste air duct. It is disclosed that it is suspended and fixed from the above.

更に特許文献3には、天井スラブ等の取付面に吊下固定される吊りボルトに、タンバックルの如き吊下耐震接続部材を介して配管を抱持する円環状のバンド抱持部が接続された、配管吊下支持具が開示されている。 Further, in Patent Document 3, an annular band holding portion that holds a pipe via a hanging seismic connection member such as a tan buckle is connected to a hanging bolt that is suspended and fixed to a mounting surface such as a ceiling slab. Further, a pipe suspension support is disclosed.

しかしながら、上述のように天井スラブに吊下固定される設備配管等は、その目的に応じて天井裏空間の内部でそれぞれが独立して配設されることが一般的であり、各々の設備配管等の配設経路の取り合い、すなわち空間的制約を考慮することが困難であった。 However, as described above, the equipment pipes and the like suspended and fixed to the ceiling slab are generally arranged independently inside the ceiling space according to the purpose, and each equipment pipe is installed. It was difficult to consider the arrangement route such as, that is, the spatial constraint.

具体的には、従来の設備配管等の配設方法においては、それぞれの設備配管等が独立して配設されるため、それぞれの設備配管等を吊下するための吊下部材(例えばワイヤや全ネジ等)を独立して天井スラブから垂下する必要があった。これにより、天井スラブから垂下する当該吊下部材の設置数が膨大になり、天井裏空間に設備配管等を配設する場合の空間的制約が特に大きかった。 Specifically, in the conventional method of arranging equipment pipes and the like, since each equipment pipe and the like are arranged independently, a hanging member (for example, a wire or a wire) for suspending each equipment pipe or the like is used. All screws, etc.) had to be hung independently from the ceiling slab. As a result, the number of the hanging members hanging from the ceiling slab becomes enormous, and the space limitation when arranging the equipment piping or the like in the space behind the ceiling is particularly large.

また、一般的に天井スラブから吊下部材を垂下する場合、当該吊下部材は天井スラブに埋設されるインサートに挿通して設けられる。このため、例えば設備配管等に設計変更が生じた場合、天井スラブに新たなインサートを埋設し、吊下部材を垂下し、更に他の設備配管等を考慮して施工を行う必要があり、設計変更にかかる設備配管等の施工に多大な労力とコストを要する場合があった。 Further, generally, when a hanging member is hung from a ceiling slab, the hanging member is provided by inserting the hanging member through an insert embedded in the ceiling slab. For this reason, for example, when a design change occurs in equipment piping, etc., it is necessary to bury a new insert in the ceiling slab, hang a hanging member, and perform construction in consideration of other equipment piping, etc. In some cases, a great deal of labor and cost were required to construct the equipment piping, etc. for the change.

本発明はかかる点に鑑みてなされたものであり、天井スラブから垂下される全ネジ等の吊下部材の設置数を削減し、また天井裏空間における設備配管等の配設が容易な天井下地構造を提供することを目的としている。 The present invention has been made in view of this point, and the number of hanging members such as all screws hanging from the ceiling slab is reduced, and the ceiling base is easily arranged in the space behind the ceiling. The purpose is to provide the structure.

前記目的を達成するため、本発明は、天井下地構造であって、天井スラブから吊下される複数の吊下部材と、それぞれの前記吊下部材に接続される耐震接続部材と、隣接する前記耐震接続部材の間に架設される複数の架橋部材と、前記耐震接続部材の下部に接続され、天井パネルが取り付けられるパネル用枠体と、を有し、前記天井スラブ、前記吊下部材及び前記架橋部材に囲まれて成る第1の空間と、前記第1の空間の下方で、前記架橋部材、前記耐震接続部材及び前記パネル用枠体に囲まれて成る第2の空間と、が形成され、天井裏設備が、前記第1の空間において前記架橋部材又は前記吊下部材に固定して配設されることを特徴としている。 In order to achieve the above object, the present invention is a ceiling base structure, in which a plurality of hanging members suspended from a ceiling slab, a seismic connecting member connected to each of the suspended members, and the adjacent above-mentioned It has a plurality of bridging members erected between the seismic connection members, and a panel frame body connected to the lower part of the seismic connection member and to which a ceiling panel is attached, and includes the ceiling slab, the suspension member, and the above. A first space surrounded by the bridging member and a second space surrounded by the bridging member, the seismic connecting member, and the panel frame are formed below the first space. The ceiling-back equipment is characterized in that it is fixedly arranged to the bridge member or the suspension member in the first space.

本発明によれば、建築構造物の天井スラブと、居室の天井面を構成する天井パネルと、の間に第1の空間と第2の空間とを形成し、上述した空調用ダクト、空調用配管、水配管、スプリンクラー配管、ガス配管、電装配線、信号配線、ルータ、アンテナ、循環ファンや各種センサなどを含む種々の天井裏設備等は、第1の空間において前記架橋部材又は前記吊下部材に固定して配設される。これにより、天井裏設備等を天井スラブから吊下することなく配設することが可能になるため、従来のように天井スラブから垂下する吊下部材の数を大幅に削減し、天井裏設備の施工を容易におこなうことができる。 According to the present invention, a first space and a second space are formed between a ceiling slab of a building structure and a ceiling panel constituting the ceiling surface of a living room, and the above-mentioned air conditioning duct and air conditioning are used. Various ceiling equipment including piping, water piping, sprinkler piping, gas piping, electrical wiring, signal wiring, routers, antennas, circulation fans, various sensors, etc. are the bridge member or the suspension member in the first space. It is fixedly arranged in the ceiling. This makes it possible to dispose of the attic equipment without hanging from the ceiling slab, so the number of hanging members hanging from the ceiling slab as in the past can be significantly reduced, and the attic equipment can be installed. Construction can be done easily.

また、このように第1の空間においては吊り金具を用いることなく吊下部材や架橋部材に固定して天井裏設備等が配設され、当該第1の空間の下方には、設備配管等が配設されない第2の空間が形成される。このため、例えば天井裏設備等に設計変更が生じた場合であっても新たな吊下部材を追加して設置する必要がなく、第2の空間を利用して容易に設計変更に対応することが可能である。 Further, in this way, in the first space, the ceiling equipment and the like are arranged by fixing to the hanging member and the cross-linking member without using the hanging metal fittings, and the equipment piping and the like are below the first space. A second space that is not disposed is formed. For this reason, for example, even if a design change occurs in the attic equipment, it is not necessary to add a new hanging member and install it, and it is possible to easily respond to the design change by using the second space. Is possible.

かかる場合、端部に位置する前記架橋部材が建築躯体に当接して設けられることが好ましい。このように、天井スラブに加えて建築躯体に対して天井下地構造を固定することで、天井下地構造の水平方向に対する揺動を抑制して、当該天井下地構造の耐震性を向上できる。 In such a case, it is preferable that the cross-linking member located at the end is provided in contact with the building frame. In this way, by fixing the ceiling base structure to the building frame in addition to the ceiling slab, it is possible to suppress the horizontal swing of the ceiling base structure and improve the earthquake resistance of the ceiling base structure.

またこのとき、前記架橋部材の建築躯体側の端部には、前記建築躯体に対向して設けられる支持材と、弾性部材とを、前記架橋部材の端部側からこの順で設けることが好ましい。このように弾性部材を設けることにより、建築躯体に建築上の誤差がある場合や、複数の架橋部材のそれぞれの長さに誤差がある場合に、これら誤差に起因する天井下地構造の変位を吸収できる。また、このように建築躯体に対向して支持体を設けることにより、建築躯体に被覆して設けられる防耐火被覆材に、架橋部材の接触に起因して損傷を与えることを抑制できる。 At this time, it is preferable to provide a support member and an elastic member provided facing the building frame at the end of the cross-linking member on the building frame side in this order from the end side of the cross-linking member. .. By providing the elastic member in this way, when there is a building error in the building frame or when there is an error in the length of each of the plurality of bridge members, the displacement of the ceiling base structure due to these errors is absorbed. can. Further, by providing the support so as to face the building frame in this way, it is possible to prevent the fireproof covering material provided by covering the building frame from being damaged due to the contact of the cross-linking member.

なお、弾性部材の端部に前記支持体を設けることに代え、当該弾性部材の端部に非鋭利化処理を施すことによっても、同様に、防耐火被覆材に損傷を与えることを抑制できる。ここで弾性部材の端部を非鋭利化処理するとは、例えば弾性部材の先端部に対する面取り加工、ゴムの取り付け又は面部材の取り付け等を行うことにより、弾性部材の端部に鋭利な部分をなくすことを言う。 In addition, instead of providing the support at the end of the elastic member, by applying a non-sharpening treatment to the end of the elastic member, it is possible to similarly suppress damage to the fireproof coating material. Here, the non-sharpening treatment of the end portion of the elastic member means that the end portion of the elastic member has no sharpened portion, for example, by chamfering the tip portion of the elastic member, attaching rubber, or attaching the surface member. Say that.

複数の前記架橋部材は格子状に配置され、前記耐震接続部材は、前記架橋部材が直交配置で接続される接続部と、前記架橋部材の接続方向に沿って、前記接続部の下方に延伸して設けられる耐震プレートと、を有していてもよい。かかる場合、前記耐震プレートは、前記接続部と接続される上辺が、前記パネル用枠体と接続される下辺よりも長く形成されることが望ましい。このように耐震プレートが設けられた耐震接続部材により前記架橋部材を相互に接続することにより、天井下地構造の耐震性を更に向上できる。 The plurality of the cross-linking members are arranged in a grid pattern, and the seismic connection member extends below the connection portion along the connection direction of the connection portion to which the cross-linking members are connected in an orthogonal arrangement. It may have a seismic plate provided in the above. In such a case, it is desirable that the seismic plate is formed so that the upper side connected to the connection portion is longer than the lower side connected to the panel frame body. By connecting the cross-linking members to each other by the seismic connection member provided with the seismic plate in this way, the seismic resistance of the ceiling base structure can be further improved.

また1つの架橋部材により相互に接続される2つの耐震接続部材は、前記耐震プレートの向きが互いに交差するように設けられることが望ましい。耐震接続部材は、耐震プレートの面方向により抵抗力の作用する方向が決定されるが、このように隣接する耐震接続部材の耐震プレートの向きを交差させることで、天井下地構造の耐震性を更に向上できる。 Further, it is desirable that the two seismic connection members connected to each other by one cross-linking member are provided so that the directions of the seismic plates intersect each other. The direction in which the resistance force acts on the seismic connection member is determined by the surface direction of the seismic plate. By crossing the directions of the seismic plates of the adjacent seismic connection members in this way, the seismic resistance of the ceiling base structure is further improved. Can be improved.

なお、本発明にかかる天井下地構造においては、建築構造物の居室内に空気を供給する空調システムの室内機を前記第2の空間に配置してもよい。かかる場合、当該室内機は前記第1の空間に配設される前記天井裏設備であるダクトと接続される。これにより室内機の本体が天井裏設備と干渉することが適切に抑制される。また、例えば当該室内機の位置を変更する必要が生じた場合であっても、天井裏設備と室内機とを接続する接続用配管の長さを変更することのみによって、容易に第2の空間の内部で室内機の位置を変更できる。 In the ceiling base structure according to the present invention, the indoor unit of the air conditioning system that supplies air to the living room of the building structure may be arranged in the second space. In such a case, the indoor unit is connected to a duct, which is an attic facility arranged in the first space. As a result, the main body of the indoor unit is appropriately suppressed from interfering with the equipment behind the ceiling. Further, for example, even if it becomes necessary to change the position of the indoor unit, the second space can be easily obtained only by changing the length of the connection pipe connecting the attic equipment and the indoor unit. The position of the indoor unit can be changed inside.

別の観点にかかる本発明は、天井下地構造の施工方法であって、天井スラブから複数の吊下部材を吊下し、それぞれの前記吊下部材に耐震接続部材を接続し、隣接する前記耐震接続部材の間に架橋部材を架設し、前記天井スラブ、前記吊下部材及び前記架橋部材に囲まれて成る第1の空間において、前記架橋部材又は前記吊下部材に固定して天井裏設備を配設し、前記耐震接続部材の下部にパネル用枠体を接続し、前記パネル用枠体に天井パネルを取り付けることを特徴としている。 The present invention according to another viewpoint is a method of constructing a ceiling base structure, in which a plurality of suspension members are suspended from a ceiling slab, a seismic connection member is connected to each of the suspension members, and the adjacent seismic resistance members are connected. A bridging member is erected between the connecting members, and in a first space surrounded by the ceiling slab, the hanging member, and the bridging member, the bridging member or the hanging member is fixed to the ceiling equipment. It is characterized in that it is arranged, a panel frame is connected to the lower part of the seismic connection member, and a ceiling panel is attached to the panel frame.

本発明によれば、天井下地構造を構成する吊下部材又は架橋部材に天井裏設備を固定するため、天井スラブから垂下して設けられる吊下部材を、当該天井下地構造を構成する吊下部材のみにできる。すなわち、天井スラブから垂下する吊下部材を従来と比較して大幅に削減できるため、容易に天井裏設備配管を施工することができる。 According to the present invention, in order to fix the attic equipment to the hanging member or the bridging member constituting the ceiling base structure, the hanging member provided by hanging from the ceiling slab is the hanging member constituting the ceiling base structure. Can only be done. That is, since the number of hanging members hanging from the ceiling slab can be significantly reduced as compared with the conventional case, it is possible to easily construct the ceiling equipment piping.

更に別の観点にかかる本発明は、天井下地構造の構成部材を接続する耐震接続部材であって、前記構成部材は、天井スラブから吊下される複数の吊下部材と、前記吊下部材の下部で水平方向に架設される複数の架橋部材と、を含み、前記耐震接続部材は、上面に前記吊下部材が接続されるとともに、平面視において前記架橋部材が直交配置で接続される接続部と、前記架橋部材の接続方向に沿って、前記接続部の下方に延伸して設けられる耐震プレートと、を有し、前記耐震プレートは、前記接続部と接続される上辺が、対向する下辺よりも長いことを特徴としている。 The present invention according to still another aspect is a seismic connection member for connecting the constituent members of the ceiling base structure, wherein the constituent member includes a plurality of suspension members suspended from the ceiling slab and the suspension member. The seismic connection member includes a plurality of bridge members erected in the horizontal direction at the lower portion, and the suspension member is connected to the upper surface of the seismic connection member, and the bridge members are connected in an orthogonal arrangement in a plan view. And a seismic plate provided extending below the connection portion along the connection direction of the cross-linking member, the seismic plate has an upper side connected to the connection portion from a lower side facing the connection portion. Is also characterized by being long.

なお、前記耐震接続部材は、4本の前記架橋部材が接続され得る接続口をなす筒状部材と、前記筒状部材を挟み込むように対向して配置される板状部材と、を有していてもよい。かかる場合、前記板状部材は略矩形形状を有することが好ましく、4本の前記筒状部材は、それぞれ前記板状部材の頂部に対応して配置されることが望ましい。このように架橋部材が接続され得る筒状部材を板状部材で挟み込むことにより、耐震接続部材の構造的強度を向上できる。 The seismic connection member has a tubular member forming a connection port to which the four cross-linking members can be connected, and a plate-shaped member arranged so as to sandwich the tubular member so as to be opposed to each other. You may. In such a case, it is preferable that the plate-shaped member has a substantially rectangular shape, and it is desirable that each of the four tubular members is arranged corresponding to the top of the plate-shaped member. By sandwiching the tubular member to which the cross-linking member can be connected between the plate-shaped members in this way, the structural strength of the seismic connection member can be improved.

前記耐震プレートは、前記上辺及び前記下辺が折り曲げられていることが好ましい。また、前記接続部と接続される前記上辺の折り曲げ部分と、前記下辺の折り曲げ部分とを接続する縦材を更に有することが更に好ましい。このように耐震プレートの下端に折り曲げ部分を形成し、更に縦材を設けることにより、耐震接続部材の構造的強度を更に向上できる。なお、前記縦材としては、例えば全ネジ等を使用できる。 It is preferable that the upper side and the lower side of the seismic plate are bent. Further, it is more preferable to further have a vertical member connecting the bent portion of the upper side connected to the connecting portion and the bent portion of the lower side. By forming a bent portion at the lower end of the seismic plate and further providing a vertical member in this way, the structural strength of the seismic connection member can be further improved. As the vertical member, for example, all screws or the like can be used.

本発明によれば、天井スラブから垂下される全ネジ等の吊下部材の設置数を削減し、また天井裏空間において設備配管等を容易に配設できる。 According to the present invention, the number of hanging members such as all screws hanging from the ceiling slab can be reduced, and equipment piping and the like can be easily arranged in the space behind the ceiling.

以下、図面を参照して、実施の形態について説明する。図1~図3は、それぞれ実施の形態にかかる天井下地構造1の構成の概略を示す斜視図、平面図及び側面図である。なお、以下の説明において、実質的に同一の機能構成を有する要素においては、同一の符号を付することにより重複説明を省略する。 Hereinafter, embodiments will be described with reference to the drawings. 1 to 3 are a perspective view, a plan view, and a side view showing an outline of the configuration of the ceiling base structure 1 according to the embodiment, respectively. In the following description, the duplicate description will be omitted by assigning the same reference numerals to the elements having substantially the same functional configuration.

The attic space S is a space formed between the ceiling panel 42 and the ceiling slab C of the building structure.

天井下地構造1は、建築構造物の天井スラブCから吊下される複数の吊下部材10と、それぞれの吊下部材10の下部に接続される耐震接続部材20と、隣接する耐震接続部材20の間を接続するように架設される架橋部材30と、耐震接続部材20の下部に接続される仕上天井ユニット40と、を有している。 The ceiling base structure 1 includes a plurality of suspension members 10 suspended from the ceiling slab C of the building structure, a seismic connection member 20 connected to the lower part of each suspension member 10, and an adjacent seismic connection member 20. It has a bridge member 30 erected so as to connect between them, and a finished ceiling unit 40 connected to the lower part of the seismic connection member 20.

吊下部材10は、建築構造物の天井スラブCに所定間隔で埋設されたインサート11から垂下して設けられ、天井下地構造1及び当該天井下地構造1に配設される天井裏設備Pを天井スラブCから吊下して固定する。吊下部材10としては、例えばインサート11に接続される全ネジ(図示参照)や、例えばインサート11に接続されたフック等に引っ掛けて支持されるワイヤ等(図示省略)を採用できる。 The hanging member 10 is provided by hanging from inserts 11 embedded in the ceiling slab C of the building structure at predetermined intervals, and is provided with the ceiling base structure 1 and the attic equipment P arranged in the ceiling base structure 1 on the ceiling. Suspend from slab C and fix. As the hanging member 10, for example, all screws connected to the insert 11 (see the figure), a wire supported by being hooked on a hook or the like connected to the insert 11, or the like (not shown) can be adopted.

吊下部材10(インサート11)は、平面視において後述の架橋部材30を格子状に配置できるように、天井スラブCに対して等間隔で設置される。吊下部材10の設置間隔は、例えば後述の天井裏設備Pに規定される支持間隔よりも小さく設定される。 The suspension member 10 (insert 11) is installed at equal intervals with respect to the ceiling slab C so that the bridge member 30 described later can be arranged in a grid pattern in a plan view. The installation interval of the hanging member 10 is set to be smaller than, for example, the support interval defined in the attic equipment P described later.

耐震接続部材20は、天井スラブCから垂下される複数の吊下部材10と、水平方向に架設される後述の架橋部材30とを接続するための部材である。天井下地構造1においては、このように耐震接続部材20により吊下部材10と架橋部材30とを接続して、後述の仕上天井ユニット40が設置される枠体を形成する。 The seismic connection member 20 is a member for connecting a plurality of suspension members 10 suspended from the ceiling slab C and a bridge member 30 to be described later, which is erected in the horizontal direction. In the ceiling base structure 1, the suspension member 10 and the cross-linking member 30 are connected by the seismic connection member 20 in this way to form a frame in which the finished ceiling unit 40 described later is installed.

図4~図6は、耐震接続部材20の構成の概略を示す斜視図、正面図及び側面図である。 4 to 6 are a perspective view, a front view, and a side view showing an outline of the configuration of the seismic connection member 20.

耐震接続部材20は、架橋部材30が接続され得る接続口をなす筒状部材21と、筒状部材21を挟み込むようにして固定する上板状部材22a及び下板状部材22b(以下、これらを併せて単に「板状部材22」という場合がある。)と、下板状部材22bの下面から下方に延伸して設けられる耐震プレート23と、を有している。 The seismic connection member 20 includes a tubular member 21 forming a connection port to which the cross-linking member 30 can be connected, and an upper plate-shaped member 22a and a lower plate-shaped member 22b (hereinafter, these are fixed by sandwiching the tubular member 21). In addition, it may be simply referred to as a "plate-shaped member 22"), and a seismic plate 23 extending downward from the lower surface of the lower plate-shaped member 22b.

筒状部材21は、上述したように平面視において後述の架橋部材30が格子状に配置されるように、平面視において複数の架橋部材30を直交して接続可能に配置されている。具体的には、例えば図7に示すように、4本の架橋部材30がそれぞれの交差角度が90°となるように接続可能に構成される。また例えば、図8に示すように、1本の架橋部材30を貫通して設けるとともに、貫通して設けられた架橋部材30と直交するように2本の架橋部材30を接続可能に構成されていてもよい。 As described above, the tubular member 21 is arranged so that a plurality of cross-linking members 30 can be connected orthogonally in a plan view so that the cross-linking members 30 described later are arranged in a grid pattern in a plan view. Specifically, for example, as shown in FIG. 7, the four cross-linking members 30 are configured to be connectable so that their respective cross-linking angles are 90 °. Further, for example, as shown in FIG. 8, one cross-linking member 30 is provided so as to penetrate through the cross-linking member 30, and two cross-linking members 30 are configured to be connectable so as to be orthogonal to the cross-linking member 30 provided through the cross-linking member 30. You may.

なお、筒状部材21は架橋部材30を挿通して接続可能な断面形状を有している。すなわち、例えば架橋部材30が角パイプである場合には断面形状が四角形状で形成され(図示参照)、例えば架橋部材30が管部材である場合には断面形状が円環形状で形成される(図示省略)。 The tubular member 21 has a cross-sectional shape that can be connected by inserting the cross-linking member 30. That is, for example, when the cross-linking member 30 is a square pipe, the cross-sectional shape is formed in a quadrangular shape (see illustration), and for example, when the cross-linking member 30 is a pipe member, the cross-sectional shape is formed in an annular shape (see illustration). Not shown).

上板状部材22a及び下板状部材22bは筒状部材21を上下方向から挟み込むように対向して配置され、筒状部材21の位置関係(接続される架橋部材30の延伸方向)を固定する。また、上板状部材22aには貫通孔24が形成され、当該貫通孔24に吊下部材10を例えば螺合することにより、吊下部材10に耐震接続部材20を固定可能に構成されている。 The upper plate-shaped member 22a and the lower plate-shaped member 22b are arranged to face each other so as to sandwich the tubular member 21 from above and below, and fix the positional relationship of the tubular member 21 (the extending direction of the connected bridging member 30). .. Further, a through hole 24 is formed in the upper plate-shaped member 22a, and the seismic connection member 20 can be fixed to the suspension member 10 by, for example, screwing the suspension member 10 into the through hole 24. ..

なお、板状部材22は平面視において矩形状や円形状等、任意の形状により形成することができるが、例えば図示のように板状部材22を矩形状に形成する場合、筒状部材21の設置方向(架橋部材30の延伸方向)を当該板状部材22の頂部に対応させることにより、耐震接続部材20の構造的な強度を向上できる。 The plate-shaped member 22 can be formed in any shape such as a rectangular shape or a circular shape in a plan view. For example, when the plate-shaped member 22 is formed in a rectangular shape as shown in the figure, the tubular member 21 may be formed. By making the installation direction (stretching direction of the cross-linking member 30) correspond to the top of the plate-shaped member 22, the structural strength of the seismic connection member 20 can be improved.

耐震プレート23は、地震等による天井下地構造1の揺動、より具体的には耐震接続部材20の下方に設けられる仕上天井ユニット40の揺動を吸収するための板状の部材であり、下板状部材22bから下方に延伸して設けられる。耐震プレート23は、例えば上辺23aが下辺23bと比較して長く形成された、正面視において略台形に形成される。耐震プレート23は、長辺である上辺23aを水平方向に折り曲げることで、当該折り曲げ部分が下板状部材22bの下面に固定される。また耐震プレート23は、短辺である下辺23bを水平方向に折り曲げることで、当該折り曲げ部分が後述の仕上天井ユニット40のパネル用枠体41と接続される。 The seismic plate 23 is a plate-shaped member for absorbing the swing of the ceiling base structure 1 due to an earthquake or the like, more specifically, the swing of the finished ceiling unit 40 provided below the seismic connection member 20. It is provided so as to extend downward from the plate-shaped member 22b. The seismic plate 23 is formed in a substantially trapezoidal shape in front view, for example, the upper side 23a is formed longer than the lower side 23b. In the seismic plate 23, the upper side 23a, which is the long side, is bent in the horizontal direction, so that the bent portion is fixed to the lower surface of the lower plate-shaped member 22b. Further, in the seismic plate 23, the lower side 23b, which is a short side, is bent in the horizontal direction, so that the bent portion is connected to the panel frame 41 of the finished ceiling unit 40 described later.

耐震プレート23は、このように上辺23a及び下辺23bに折り曲げ部分が形成されることで、当該耐震プレート23の構造的な強度を向上できる。 The seismic plate 23 can improve the structural strength of the seismic plate 23 by forming the bent portions on the upper side 23a and the lower side 23b in this way.

また耐震プレート23は、図示のように上辺23aが架橋部材30の延伸方向と一致するように、換言すれば架橋部材30により形成される格子形状に沿うように、下板状部材22bの下面に固定される。天井下地構造1は、格子形状を構成する架橋部材30の延伸方向に対する揺動が特に懸念されるが、このように耐震プレート23を格子形状に沿って設けることで、天井下地構造1で懸念される揺動を適切に減衰できる。 Further, the seismic plate 23 is provided on the lower surface of the lower plate-shaped member 22b so that the upper side 23a coincides with the stretching direction of the cross-linking member 30 as shown in the figure, in other words, the seismic plate 23 follows the grid shape formed by the cross-linking member 30. It is fixed. In the ceiling base structure 1, there is a particular concern about the swing of the cross-linking member 30 constituting the grid shape with respect to the stretching direction. However, by providing the seismic plate 23 along the grid shape in this way, there is a concern in the ceiling base structure 1. The fluctuation can be appropriately damped.

また本実施の形態にかかる天井下地構造1においては、図示のように、1つの架橋部材30により接続される、2つの耐震接続部材20を、それぞれの耐震プレート23の面方向が互いに交差(望ましくは直交)するように交差配置で設置する。これにより、架橋部材30の延伸方向(直交方向)のそれぞれに対する天井下地構造1の揺動を適切に吸収でき、当該天井下地構造1の耐震性を向上できる。 Further, in the ceiling base structure 1 according to the present embodiment, as shown in the figure, the two seismic connection members 20 connected by one cross-linking member 30 intersect with each other in the plane direction of each seismic plate 23 (desirably). Are installed in a cross-linked arrangement so that they are orthogonal to each other. As a result, the vibration of the ceiling base structure 1 with respect to each of the stretching directions (orthogonal directions) of the cross-linking member 30 can be appropriately absorbed, and the seismic resistance of the ceiling base structure 1 can be improved.

なお、図示は省略するが、このように架橋部材30の延伸方向(直交方向)のそれぞれに対する天井下地構造1の揺動を吸収する観点から、耐震接続部材20の耐震プレート23は、架橋部材30の延伸方向に沿って、平面視において十字状に配置されていてもよい。 Although not shown, the seismic plate 23 of the seismic connection member 20 is the cross-linking member 30 from the viewpoint of absorbing the vibration of the ceiling base structure 1 in each of the extending directions (orthogonal directions) of the cross-linking member 30. It may be arranged in a cross shape in a plan view along the stretching direction of the.

なお、図示は省略するが、天井下地構造1の耐震性を向上させる観点からは、下板状部材22bの下面に設けられる耐震プレート23に加えて、上板状部材22aの上面から上方に延伸するように、更に耐震プレート23が設けられていてもよい。このとき、上板状部材22aの上面側に設けられる耐震プレート23を、平面視において下板状部材22bの下面側に設けられる耐震プレート23と交差して設けることで、天井下地構造1の耐震性を更に適切に向上できる。 Although not shown, from the viewpoint of improving the seismic resistance of the ceiling base structure 1, in addition to the seismic plate 23 provided on the lower surface of the lower plate-shaped member 22b, it extends upward from the upper surface of the upper plate-shaped member 22a. As such, a seismic plate 23 may be further provided. At this time, the seismic plate 23 provided on the upper surface side of the upper plate-shaped member 22a is provided so as to intersect with the seismic plate 23 provided on the lower surface side of the lower plate-shaped member 22b in a plan view. The sex can be improved more appropriately.

また耐震接続部材20には、図6に示すように、上辺23aの折り曲げ部分と下辺23bの折り曲げ部分とを接続するように縦材25が設けられていてもよい。縦材25は、このように上辺23aと下辺23bとを接続するように、耐震プレート23の板面と並行して設けられる。そして、このように縦材25が設けられることにより、耐震プレート23の構造的な強度を向上できる。縦材25としては、例えば全ネジ(図示参照)やワイヤ等(図示省略)を採用できる。また、縦材25として全ネジを用いる場合には、天井スラブCから吊下される吊下部材10と縦材25を一体に構成してもよい。すなわち、板状部材22を貫通させ、耐震プレート23の下辺23bに吊下部材10を接続するようにしてもよい。 Further, as shown in FIG. 6, the seismic connection member 20 may be provided with a vertical member 25 so as to connect the bent portion of the upper side 23a and the bent portion of the lower side 23b. The vertical member 25 is provided in parallel with the plate surface of the seismic plate 23 so as to connect the upper side 23a and the lower side 23b in this way. By providing the vertical member 25 in this way, the structural strength of the seismic plate 23 can be improved. As the vertical member 25, for example, all screws (see the figure), wires, or the like (not shown) can be adopted. Further, when all the screws are used as the vertical member 25, the hanging member 10 suspended from the ceiling slab C and the vertical member 25 may be integrally configured. That is, the plate-shaped member 22 may be penetrated and the hanging member 10 may be connected to the lower side 23b of the seismic plate 23.

なお、実施の形態においては筒状部材21に対して架橋部材30を挿通して接続したが、例えば筒状部材21の端部と架橋部材30の端部を相互に嵌め込んで接続されるように、筒状部材21を構成してもよい。 In the embodiment, the cross-linking member 30 is inserted and connected to the cylindrical member 21, but for example, the end portion of the tubular member 21 and the end portion of the cross-linking member 30 are fitted and connected to each other. In addition, the tubular member 21 may be configured.

図1~図3を参照した天井下地構造1の説明に戻る。 The explanation returns to the explanation of the ceiling base structure 1 with reference to FIGS. 1 to 3.

架橋部材30は、吊下部材10の下部において、水平方向に延伸するように配設される部材であって、2つの耐震接続部材20の間を接続するように架設されることで、建築構造物の天井スラブCから吊下される。架橋部材30としては、例えばステンレスやアルミニウム等から成る角パイプや管部材等を採用できる。架橋部材30は、耐震接続部材20の筒状部材21と接続されることで、上述したように平面視において格子形状を形成する。 The cross-linking member 30 is a member arranged so as to extend in the horizontal direction at the lower part of the suspension member 10, and is erected so as to connect between the two seismic connecting members 20 to form a building structure. Suspended from the ceiling slab C of an object. As the cross-linking member 30, for example, a square pipe or a pipe member made of stainless steel, aluminum, or the like can be adopted. The cross-linking member 30 is connected to the tubular member 21 of the seismic connection member 20 to form a lattice shape in a plan view as described above.

また、天井下地構造1の端部に配置される架橋部材30は、図9及び図10に示すように、その先端部が建築構造物の天井スラブCに形成された大梁Bに当接して設けられることで、建築構造物に対して固定されることが望ましい。端部に配置される架橋部材30の長さは、例えば所定長さの架橋部材30を切断することにより調整してもよいし、また例えば架橋部材30を長手方向に伸縮自在に構成することにより調整してもよい。換言すれば、このように架橋部材30の長さを適宜調整することにより、架橋部材30の端部位置を任意に調整できる。 Further, as shown in FIGS. 9 and 10, the bridging member 30 arranged at the end of the ceiling base structure 1 is provided with its tip abutting against the girder B formed on the ceiling slab C of the building structure. It is desirable that it be fixed to the building structure. The length of the cross-linking member 30 arranged at the end may be adjusted, for example, by cutting the cross-linking member 30 having a predetermined length, or by forming the cross-linking member 30 so as to be stretchable in the longitudinal direction, for example. You may adjust. In other words, by appropriately adjusting the length of the cross-linking member 30 in this way, the position of the end portion of the cross-linking member 30 can be arbitrarily adjusted.

本実施形態においては、このように、架橋部材30を大梁Bに対して当接させることで、天井下地構造1が水平方向に固定、すなわち、例えば地震等による天井下地構造1の水平方向の揺動が抑制され、当該天井下地構造1の耐震性が向上する。なお、大梁Bには、その表面を被覆するように防耐火被覆材Fが設けられる場合があるが、本発明にかかる技術においては、かかる防耐火被覆材Fを含めて「大梁」と呼称する場合があるものとする。 In the present embodiment, the ceiling base structure 1 is fixed in the horizontal direction by bringing the bridge member 30 into contact with the girder B in this way, that is, the ceiling base structure 1 is shaken in the horizontal direction due to, for example, an earthquake or the like. The movement is suppressed, and the earthquake resistance of the ceiling base structure 1 is improved. The girder B may be provided with a fireproof coating material F so as to cover the surface thereof, but in the technique according to the present invention, the girder B including the fireproof covering material F is referred to as a “girder”. There may be cases.

なお、以下の説明においては、このように架橋部材30を建築躯体としての大梁Bに当接させることで、天井下地構造1を建築構造物に対して固定する場合を例に説明を行うが、架橋部材30が当接されるのは大梁Bでなくてもよい。具体的には、天井下地構造1を建築構造物に対して固定できれば、架橋部材30は建築躯体としての横梁や支柱等に当接されていてもよい。なお、前述の防耐火被覆材Fが、本発明の技術にかかる「建築躯体」に含まれる場合があるものとする。 In the following description, the case where the ceiling base structure 1 is fixed to the building structure by bringing the cross-linking member 30 into contact with the girder B as the building frame will be described as an example. It is not necessary for the cross-linking member 30 to come into contact with the girder B. Specifically, if the ceiling base structure 1 can be fixed to the building structure, the cross-linking member 30 may be in contact with a cross beam, a support, or the like as a building frame. In addition, it is assumed that the above-mentioned fireproof coating material F may be included in the "building frame" according to the technique of the present invention.

なお、例えば大梁Bに当接して設けられる複数の架橋部材30の間で長さに誤差がある場合や、大梁Bに建築上の誤差が生じている場合、又は防耐火被覆材Fの厚みに誤差がある場合、地震等による天井下地構造1の揺動に際して、大梁B(防耐火被覆材F)と適切に当接する架橋部材30と、適切に当接されない架橋部材30と、が発生する場合がある。このように一部の架橋部材30のみが大梁Bに当接する場合、地震等での揺動に際しての大梁Bに作用する荷重に偏りが生じ、天井下地構造1に損傷が生じるおそれがある。 It should be noted that, for example, when there is an error in the length between the plurality of cross-linking members 30 provided in contact with the girder B, when there is an architectural error in the girder B, or when the thickness of the fireproof coating material F is increased. When there is an error, when the ceiling base structure 1 swings due to an earthquake or the like, a cross-linking member 30 that appropriately contacts the girder B (fireproof coating material F) and a cross-linking member 30 that does not properly contact the girder B (fireproof coating material F) occur. There is. When only a part of the cross-linking members 30 abuts on the girder B in this way, the load acting on the girder B at the time of rocking due to an earthquake or the like is biased, and the ceiling base structure 1 may be damaged.

そこで本実施の形態にかかる架橋部材30の端部には、地震等での揺動に際して発生する荷重を吸収するための弾性部材31が設けられることが好ましい。弾性部材31としては、例えばバネやゴム等を採用できる。これにより、架橋部材30と大梁Bとの接触にかかる変位を弾性部材31で吸収でき、すなわち架橋部材30にかかる荷重を軽減して天井下地構造1の損傷を抑制できる。 Therefore, it is preferable that an elastic member 31 for absorbing a load generated at the time of rocking due to an earthquake or the like is provided at the end of the cross-linking member 30 according to the present embodiment. As the elastic member 31, for example, a spring, rubber, or the like can be adopted. As a result, the displacement of the contact between the cross-linking member 30 and the girder B can be absorbed by the elastic member 31, that is, the load applied to the cross-linking member 30 can be reduced and damage to the ceiling base structure 1 can be suppressed.

また、架橋部材30(弾性部材31)の端部に鋭利な部分が形成されている場合、これにより防耐火被覆材Fを剥離してしまうおそれがある。かかる防耐火被覆材Fの剥離を抑制するため、防耐火被覆材Fに当接される架橋部材30(弾性部材31)の端部には、大梁Bに面して支持材32が配置されることが好ましい。支持材32は、例えば図示のように大梁Bに面した平面を備えることが好ましい。このように支持材32を配置することで、防耐火被覆材Fの剥離を抑制できるとともに、上述した地震等での揺動に際して架橋部材30にかかる荷重分散させて軽減できる。 Further, if a sharp portion is formed at the end portion of the cross-linking member 30 (elastic member 31), the fireproof coating material F may be peeled off due to this. In order to suppress the peeling of the fireproof coating material F, a support material 32 is arranged at the end of the cross-linking member 30 (elastic member 31) that comes into contact with the fireproof coating material F so as to face the girder B. Is preferable. The support member 32 preferably includes, for example, a flat surface facing the girder B as shown in the figure. By arranging the support material 32 in this way, it is possible to suppress the peeling of the fireproof coating material F, and it is possible to disperse and reduce the load applied to the cross-linking member 30 when rocking due to the above-mentioned earthquake or the like.

なお、防耐火被覆材Fの剥離を抑制するという観点からは、架橋部材30(弾性部材31)の端部の鋭利な部分を無くすように非鋭利化処理を施してもよい。非鋭利化処理としては、例えば架橋部材30(弾性部材31)の端部に対する面取り加工(丸み加工)、弾性部材(例えばゴム等)の取り付け、又は面部材の取り付け等が挙げられる。このように架橋部材30(弾性部材31)の端部に鋭利な部分を無くすことにより、防耐火被覆材Fに損傷を与えることを抑制できる。 From the viewpoint of suppressing the peeling of the fireproof coating material F, a non-sharpening treatment may be performed so as to eliminate the sharp portion at the end of the cross-linking member 30 (elastic member 31). Examples of the non-sharpening treatment include chamfering (rounding), attachment of an elastic member (for example, rubber, etc.) to the end of the cross-linking member 30 (elastic member 31), attachment of a surface member, and the like. By eliminating the sharp portion at the end of the cross-linking member 30 (elastic member 31) in this way, it is possible to suppress damage to the fireproof coating material F.

なお、図9及び図10に示した実施の形態においては大梁Bの表面に設けられた防耐火被覆材Fに架橋部材30(支持材32)を当接させることにより天井下地構造1を固定したが、図11に示すように、大梁Bに対して直接的に架橋部材30(支持材32)を当接させてもよい。 In the embodiment shown in FIGS. 9 and 10, the ceiling base structure 1 is fixed by abutting the cross-linking member 30 (support material 32) on the fireproof coating material F provided on the surface of the girder B. However, as shown in FIG. 11, the cross-linking member 30 (support member 32) may be brought into direct contact with the girder B.

また、図9~図11に示した例においては、架橋部材30(支持材32)を大梁Bに対して常時当接させたが、架橋部材30は、例えば地震等による天井下地構造1の揺動時にのみ大梁B(建築躯体)に対して当接されてもよい。かかる場合、通常時において架橋部材30の端部は大梁Bから所定の間隔をあけて配置される。 Further, in the examples shown in FIGS. 9 to 11, the cross-linking member 30 (support member 32) is always in contact with the girder B, but the cross-linking member 30 is shaken by the ceiling base structure 1 due to, for example, an earthquake or the like. It may be in contact with the girder B (building frame) only when it is moving. In such a case, the end portions of the cross-linking member 30 are normally arranged at a predetermined distance from the girder B.

仕上天井ユニット40は、耐震接続部材20の下方に吊下されるパネル用枠体41と、当該パネル用枠体41の下面に取り付けられる天井パネル42と、を有している。 The finished ceiling unit 40 has a panel frame 41 suspended below the seismic connection member 20, and a ceiling panel 42 attached to the lower surface of the panel frame 41.

パネル用枠体41は、耐震プレート23の下辺23bの折り曲げ部分に接続されることで天井スラブCから吊下される部材であり、平面視において複数の天井パネル42を並べて取り付けられるように構成される。 The panel frame 41 is a member suspended from the ceiling slab C by being connected to the bent portion of the lower side 23b of the seismic plate 23, and is configured so that a plurality of ceiling panels 42 can be mounted side by side in a plan view. To.

天井パネル42は、居室Rの仕上げ天井面を形成する板状の部材であり、例えば石膏ボード等により形成される。そして、このように天井パネル42が施工されることにより、当該天井パネル42と天井スラブCとの間に天井裏空間Sが形成される。 The ceiling panel 42 is a plate-shaped member that forms the finished ceiling surface of the living room R, and is formed of, for example, gypsum board or the like. Then, by constructing the ceiling panel 42 in this way, the attic space S is formed between the ceiling panel 42 and the ceiling slab C.

なお、上述したように大梁Bに対して架橋部材30の長さ(端部の位置)が調整された場合、このように長さが調整された架橋部材30と対応する位置における仕上天井ユニット40(パネル用枠体41及び天井パネル42)についても、その長さが適宜調整可能である。すなわち、パネル用枠体41及び天井パネル42は、例えば切断により長さ(幅)が調整されてもよいし、伸縮可能に構成されていてもよい。また仕上天井ユニット40は、例えばこのように架橋部材30の長さに合わせて設置するため、端部幅の異なる仕上天井ユニット40が、予め各種用意されていてもよい。 When the length (position of the end portion) of the cross-linking member 30 is adjusted with respect to the girder B as described above, the finished ceiling unit 40 at the position corresponding to the cross-linking member 30 whose length is adjusted in this way. The lengths of (panel frame 41 and ceiling panel 42) can also be adjusted as appropriate. That is, the length (width) of the panel frame 41 and the ceiling panel 42 may be adjusted by cutting, for example, or may be configured to be expandable and contractible. Further, since the finished ceiling unit 40 is installed according to the length of the cross-linking member 30, for example, various finished ceiling units 40 having different end widths may be prepared in advance.

また、本実施の形態にかかる天井下地構造1においては、側面視において、天井スラブC、吊下部材10及び架橋部材30に囲まれてなる第1の空間S1と、耐震接続部材20、架橋部材30及びパネル用枠体41に囲まれてなる第2の空間S2とが形成される。すなわち、本実施形態にかかる天井裏空間Sにおいては、第1の空間S1と第2の空間S2とが、上方(天井スラブC側)からこの順に形成されている。 Further, in the ceiling base structure 1 according to the present embodiment, in the side view, the ceiling slab C, the first space S1 surrounded by the hanging member 10 and the cross-linking member 30, the seismic connection member 20, and the cross-linking member 20 are provided. A second space S2 surrounded by the 30 and the panel frame 41 is formed. That is, in the attic space S according to the present embodiment, the first space S1 and the second space S2 are formed in this order from above (ceiling slab C side).

第1の空間S1には、図1~図3に示したように、天井裏設備P等が配設される。換言すれば第1の空間S1は、天井裏設備P等の配設用空間として作用する。天井裏設備Pは、例えば第1の空間S1を画成する吊下部材10や架橋部材30に対して、固定部材50を用いて固定されている。固定部材50としては、例えばU字金具やサドルバンド、又は蝶番式バンド等の任意の固定部材を採用できる。 As shown in FIGS. 1 to 3, the attic equipment P and the like are arranged in the first space S1. In other words, the first space S1 acts as an arrangement space for the attic equipment P and the like. The attic equipment P is fixed to, for example, the hanging member 10 and the cross-linking member 30 that define the first space S1 by using the fixing member 50. As the fixing member 50, any fixing member such as a U-shaped metal fitting, a saddle band, or a hinge type band can be adopted.

なお、第1の空間S1に配設される天井裏設備Pとしては、例えば空調用ダクト、空調用配管、循環ファン、排水配管や給水配管等の水配管、スプリンクラー配管、通気配管、ガス配管、電装配線、信号配線、電話配線、テレビアンテナ配線、ルータ、アンテナ、LANケーブル、又は各種センサ等、天井裏空間Sに配設され得る種々の設備等が任意に選択され得る。 The ceiling equipment P arranged in the first space S1 includes, for example, air conditioning ducts, air conditioning pipes, circulation fans, water pipes such as drainage pipes and water supply pipes, sprinkler pipes, ventilation pipes, and gas pipes. Various facilities that can be arranged in the ceiling space S, such as electrical wiring, signal wiring, telephone wiring, TV antenna wiring, routers, antennas, LAN cables, and various sensors, can be arbitrarily selected.

このように実施の形態にかかる天井下地構造1においては、従来のように天井裏設備P等を天井スラブCに対して吊下固定することに代え、天井下地構造1を構成する吊下部材10や架橋部材30に対して固定部材50を用いて固定する。このように、実施の形態にかかる天井下地構造1は天井パネル42が設置される下地材としての機能と、天井裏設備Pを固定する支持材としての機能を兼用する。これにより、本実施の形態においては天井下地構造1を構成する吊下部材10のみを天井スラブCから垂下させればよいため、天井スラブCに埋設されるインサート及び垂下される吊下部材の設置数を従来と比較して大幅に削減できる。 In the ceiling base structure 1 according to the embodiment as described above, instead of suspending and fixing the attic equipment P or the like to the ceiling slab C as in the conventional case, the hanging member 10 constituting the ceiling base structure 1 is used. And the bridge member 30, the fixing member 50 is used to fix the member. As described above, the ceiling base structure 1 according to the embodiment has both a function as a base material on which the ceiling panel 42 is installed and a function as a support material for fixing the attic equipment P. As a result, in the present embodiment, only the hanging member 10 constituting the ceiling base structure 1 needs to be hung from the ceiling slab C, so that the insert embedded in the ceiling slab C and the hanging member are installed. The number can be significantly reduced compared to the past.

このとき、天井スラブCに対するインサート11の埋設位置は、それぞれの天井裏設備Pの配管経路に対応させて決定する必要がなく、天井下地構造1を構成する吊下部材10を垂下するための所定間隔で決定されればよい。すなわち、天井裏設備P等の配管経路に依らず、所定間隔ごとに機械的にインサート11の埋設位置を決定できるため、天井下地構造1の施工にかかる時間を適切に削減できる。 At this time, the burying position of the insert 11 with respect to the ceiling slab C does not need to be determined according to the piping path of each attic equipment P, and is predetermined for hanging the hanging member 10 constituting the ceiling base structure 1. It may be determined by the interval. That is, since the embedding position of the insert 11 can be mechanically determined at predetermined intervals regardless of the piping route of the ceiling equipment P or the like, the time required for the construction of the ceiling base structure 1 can be appropriately reduced.

また、このように天井下地構造1から垂下される吊下部材10の数が削減されるため、当該吊下部材10と天井裏設備Pの配設経路との干渉が抑制され、天井裏空間Sにおける天井裏設備Pの配管経路設計、及び施工が極めて容易になる。 Further, since the number of hanging members 10 hanging from the ceiling base structure 1 is reduced in this way, interference between the hanging members 10 and the arrangement path of the attic equipment P is suppressed, and the attic space S is suppressed. The piping route design and construction of the ceiling equipment P in the ceiling will be extremely easy.

また更に、例えば天井裏設備Pの配管経路に設計変更が生じた場合であっても、天井裏設備Pは架橋部材30等に固定することのみによって配設されるため、従来のように天井スラブCに対して新たなインサート11を埋設する必要がなく、吊下部材10を新たに用意する必要もない。これにより、設計変更にかかる天井裏設備Pの施工にかかるコストや労力を大幅に削減できる。 Furthermore, for example, even if the piping path of the attic equipment P is changed in design, the attic equipment P is arranged only by fixing it to the cross-linking member 30 or the like, so that the ceiling slab is disposed as in the conventional case. It is not necessary to bury a new insert 11 in C, and it is not necessary to newly prepare a hanging member 10. As a result, the cost and labor required for the construction of the attic equipment P for the design change can be significantly reduced.

また本実施の形態によれば、天井裏設備Pは天井スラブC及び大梁Bに対して固定された天井下地構造1に対して直接的に固定される。これにより、天井裏設備Pは天井下地構造1と一体に構成されるため、天井スラブCに対して独立して天井裏設備Pが吊下される場合と比較して、容易に当該天井裏設備Pの耐震性能を担保することができる。 Further, according to the present embodiment, the attic equipment P is directly fixed to the ceiling base structure 1 fixed to the ceiling slab C and the girder B. As a result, since the attic equipment P is integrally configured with the ceiling base structure 1, the attic equipment P can be easily suspended as compared with the case where the attic equipment P is suspended independently of the ceiling slab C. The seismic performance of P can be guaranteed.

更に本実施の形態によれば、吊下部材10(インサート11)の設置間隔は、上述のように天井下地構造1に配設される天井裏設備Pに規定される支持間隔よりも小さく設定される。このため、配管経路中に存在する吊下部材10や架橋部材30毎に天井裏設備Pを固定することで、適切に施工基準を満たした支持間隔で天井裏設備Pの配設を行うことができる。 Further, according to the present embodiment, the installation interval of the hanging member 10 (insert 11) is set to be smaller than the support interval defined in the attic equipment P arranged in the ceiling base structure 1 as described above. To. Therefore, by fixing the attic equipment P for each of the hanging member 10 and the cross-linking member 30 existing in the piping route, the attic equipment P can be arranged at a support interval that appropriately satisfies the construction standard. can.

なお、天井裏設備Pは、その種類によって所定の勾配をつけて配設する必要がある。かかる場合、例えば図12に示すように、架橋部材30と天井裏設備Pとの間にスペーサ51を介在させることにより、当該天井裏設備Pに勾配をつけることが可能である。スペーサ51の材料は特に限定されるものではないが、天井裏設備Pと架橋部材30との間における熱伝導を抑制するため、断熱性を有する材料により構成されることが好ましい。または、例えば天井裏設備Pとスペーサ51との間に、更に断熱部材(図示せず)を介在させてもよい。 The attic equipment P needs to be arranged with a predetermined gradient depending on the type of the equipment P. In such a case, for example, as shown in FIG. 12, by interposing a spacer 51 between the cross-linking member 30 and the attic equipment P, it is possible to give a gradient to the attic equipment P. The material of the spacer 51 is not particularly limited, but it is preferably made of a material having heat insulating properties in order to suppress heat conduction between the ceiling equipment P and the cross-linking member 30. Alternatively, for example, a heat insulating member (not shown) may be further interposed between the attic equipment P and the spacer 51.

第2の空間S2は、例えば第1の空間S1に対する天井裏設備Pの配設作業等を実施するための作業用空間として作用する。本実施の形態においては、上述のように天井裏設備Pは第1の空間S1に配設され、第2の空間S2には配設されないため、適切に天井裏設備Pの施工にかかる作業用空間を確保することが容易である。 The second space S2 acts as a work space for carrying out, for example, the arrangement work of the attic equipment P with respect to the first space S1. In the present embodiment, as described above, the attic equipment P is arranged in the first space S1 and not in the second space S2, so that it is suitable for work related to the construction of the attic equipment P. It is easy to secure space.

なお、例えば居室Rに対して空気を供給する空調システムの室内機60や、居室Rの調光を行う照明器具61を天井裏空間Sに設ける必要がある場合、これら室内機60や照明器具61は、図13に示すように、第2の空間S2に設置されてもよい。かかる場合、当該室内機60及び照明器具61は、接続用配管62を介して第1の空間S1に配設された天井裏設備Pと接続される。 For example, when it is necessary to provide an indoor unit 60 of an air conditioning system that supplies air to the living room R and a lighting fixture 61 for dimming the living room R in the ceiling space S, these indoor units 60 and the lighting fixture 61. May be installed in the second space S2 as shown in FIG. In such a case, the indoor unit 60 and the lighting fixture 61 are connected to the attic equipment P arranged in the first space S1 via the connection pipe 62.

また、天井裏空間Sに面する天井パネル42の裏面側には、居室Rと天井裏空間Sとの間における熱伝達を抑制して、居室Rにおける空調効率を向上させるための放射パネル(図示せず)が設置されていてもよい。放射パネルの内部には冷媒流路が形成され、当該冷媒流路の内部に冷媒(例えば冷温水)が通流される。かかる場合、冷媒流路は、接続用配管(放射パネル用の接続用配管の図示は省略)を介して第1の空間S1に配設された天井裏設備Pと接続される。 Further, on the back surface side of the ceiling panel 42 facing the attic space S, a radiant panel for suppressing heat transfer between the living room R and the attic space S to improve the air conditioning efficiency in the living room R (FIG. (Not shown) may be installed. A refrigerant flow path is formed inside the radiation panel, and a refrigerant (for example, cold / hot water) is passed through the inside of the refrigerant flow path. In such a case, the refrigerant flow path is connected to the attic equipment P arranged in the first space S1 via a connection pipe (not shown of the connection pipe for the radiation panel).

また更に、天井裏空間Sに面する天井パネル42の裏面側には、図14に示すように、居室Rに送風される空気の流量を個別に設定可能な可変風量装置70が設置されていてもよい。可変風量装置70は、例えば接続用配管62を介して第1の空間S1に配設された天井裏設備Pとしてのダクトと接続される。 Further, as shown in FIG. 14, a variable air volume device 70 capable of individually setting the flow rate of the air blown to the living room R is installed on the back surface side of the ceiling panel 42 facing the ceiling space S. May be good. The variable air volume device 70 is connected to a duct as an attic facility P arranged in the first space S1 via, for example, a connection pipe 62.

可変風量装置70は、接続用配管62から供給される空気の風速を測定する風速測定センサ71と、居室Rに供給する空気風量を制御する風量調整機構72と、風量調整機構72の動作を制御するコントローラ73と、を有している。 The variable air volume device 70 controls the operation of the wind speed measurement sensor 71 that measures the wind speed of the air supplied from the connection pipe 62, the air volume adjusting mechanism 72 that controls the air air volume supplied to the living room R, and the air volume adjusting mechanism 72. It has a controller 73 and a controller 73.

風量調整機構72は、図15に示すように、パンチング孔が形成された2枚のパンチング板72a、72bを備えている。風量調整機構72は、2枚のパンチング板72a、72bのうち、一方(図示の例ではパンチング板72a)が固定配置され、他方(図示の例ではパンチング板72b)をスライド自在に配置されている。また、パンチング孔はパンチング板72bのスライド方向に対して四角形、より具体的には菱形形状に形成されている。 As shown in FIG. 15, the air volume adjusting mechanism 72 includes two punching plates 72a and 72b having punching holes formed therein. In the air volume adjusting mechanism 72, one of the two punching plates 72a and 72b (the punching plate 72a in the illustrated example) is fixedly arranged, and the other (the punching plate 72b in the illustrated example) is slidably arranged. .. Further, the punching holes are formed in a quadrangular shape, more specifically in a rhombic shape, with respect to the sliding direction of the punching plate 72b.

そして可変風量装置70においては、図15に示すようにパンチング板72bをパンチング板72aに対して相対的に移動させることにより、天井裏設備Pとしてのダクトから供給される空気を適切な流量で居室Rへと導入できる。また、このように天井裏設備Pとしてのダクトから供給される空気を、第2の空間S2に設置される可変風量装置70毎に独立して制御できるため、図14に示したように、居室Rにおいて間仕切壁Wの位置が変更になった場合であっても、天井裏設備Pとしてのダクトに通流する空気の流量や流速を変えることなく、可変風量装置70の制御により適切に居室Rに対する風量を変更できる。 Then, in the variable air volume device 70, as shown in FIG. 15, by moving the punching plate 72b relative to the punching plate 72a, the air supplied from the duct as the ceiling equipment P is in the living room at an appropriate flow rate. Can be introduced to R. Further, since the air supplied from the duct as the ceiling equipment P can be independently controlled for each variable air flow rate device 70 installed in the second space S2, as shown in FIG. 14, the living room. Even if the position of the partition wall W is changed in R, the living room R can be appropriately controlled by controlling the variable air volume device 70 without changing the flow rate or flow velocity of the air flowing through the duct as the ceiling equipment P. You can change the air volume for.

従来、このような居室Rにおける間仕切壁Wの位置の変更に対応する場合、天井裏設備Pとしてのダクトの配置の増減や変更、ダクト内の風量調整弁の開度の変更等の設計変更が必要となり、居室Rにおける間仕切壁Wの位置変更への対応には多大な労力やコストを要していた。しかしながら、上述したように第2の空間S2に可変風量装置70を配置することにより、ダクトと吹出口の位置関係等の変更が不要であり、すなわち居室Rにおける間仕切壁Wの位置変更への対応が極めて容易であるとともに、コストを大幅に削減できる。また、それぞれの可変風量装置70に風量調整機構72が設けられているため、居室Rに対する空気の供給量の調整も極めて容易に行うことができる。 Conventionally, when responding to such a change in the position of the partition wall W in the living room R, design changes such as increase / decrease or change in the arrangement of the duct as the attic equipment P and change in the opening degree of the air volume adjusting valve in the duct are required. It became necessary, and it took a lot of labor and cost to cope with the change of the position of the partition wall W in the living room R. However, by arranging the variable air volume device 70 in the second space S2 as described above, it is not necessary to change the positional relationship between the duct and the air outlet, that is, it corresponds to the position change of the partition wall W in the living room R. Is extremely easy, and the cost can be significantly reduced. Further, since the air volume adjusting mechanism 72 is provided in each variable air volume device 70, the air supply amount to the living room R can be adjusted extremely easily.

また、本実施の形態においては、パンチング孔がパンチング板72bのスライド方向に対して菱形形状で形成されているため、パンチング板72bのスライド量に対して指数関数的に居室Rに対する空気の供給量を制御できる。換言すれば、居室Rに対する空気の供給量を瞬時に制御できる。 Further, in the present embodiment, since the punching hole is formed in a diamond shape with respect to the slide direction of the punching plate 72b, the amount of air supplied to the living room R exponentially with respect to the slide amount of the punching plate 72b. Can be controlled. In other words, the amount of air supplied to the living room R can be instantly controlled.

なお、風量調整機構72の動作は、例えば風速測定センサ71による測定結果に基づいてコントローラ73により自動制御されてもよいし、例えば居室R側から手動により制御されてもよい。 The operation of the air volume adjusting mechanism 72 may be automatically controlled by the controller 73 based on the measurement result of the wind speed measurement sensor 71, or may be manually controlled from the living room R side, for example.

また、図15においてはパンチング板72a、72bに形成されたパンチング孔が四角形である場合を例に図示を行ったが、パンチング孔の形状はこれに限定されず、例えば円形状であってもよい。このようにパンチング孔を円形状で形成することにより、居室Rに対する空気の供給量を瞬時に制御できる。
また、図15においてはスライド方向に対して菱形形状を有する四角形によりパンチング孔を形成したが、スライド方向に対して矩形状の四角形によりパンチング孔を形成してもよい。かかる場合、パンチング板72bのスライド量に比例して居室Rに対する空気の供給量を制御できる。
Further, in FIG. 15, the case where the punching holes formed in the punching plates 72a and 72b are quadrangular is shown as an example, but the shape of the punching holes is not limited to this, and may be, for example, a circular shape. .. By forming the punching holes in a circular shape in this way, the amount of air supplied to the living room R can be instantly controlled.
Further, in FIG. 15, the punching hole is formed by a quadrangle having a rhombic shape in the slide direction, but the punching hole may be formed by a quadrangle having a rectangular shape in the slide direction. In such a case, the amount of air supplied to the living room R can be controlled in proportion to the amount of slide of the punching plate 72b.

このように本実施の形態においては、室内機60、照明器具61、放射パネル又は可変風量装置70のような設備器具の本体と、設備器具に対して動力等を供給する天井裏設備Pとをそれぞれ第1の空間S1と第2の空間S2に設けることで、設備器具が天井裏設備Pと干渉することがない。すなわち、天井裏空間Sに対して極めて容易に設備器具の本体を設置することが可能である。 As described above, in the present embodiment, the main body of the equipment such as the indoor unit 60, the lighting equipment 61, the radiation panel or the variable air volume device 70, and the ceiling equipment P that supplies power to the equipment and the like are provided. By providing the equipment in the first space S1 and the second space S2, respectively, the equipment does not interfere with the ceiling equipment P. That is, it is possible to install the main body of the equipment very easily in the space S behind the ceiling.

また例えば、居室Rにおいて配置替えが行われ、設備器具の設置位置を変更する必要が生じた場合であっても、当該設備器具と、変更先に位置する天井パネル42との位置を交換することのみによって、容易に設備器具の設置位置を変更することが可能である。このとき、当該設備器具は接続用配管62を介して天井裏設備Pと接続されるため、例えば図16に示すように、天井裏設備Pの配管経路を変更することなく接続用配管62の配廻しを変更することのみによって、極めて容易に設備器具の位置を変更できる。 Further, for example, even when the arrangement is performed in the living room R and it becomes necessary to change the installation position of the equipment, the position of the equipment and the ceiling panel 42 located at the change destination should be exchanged. It is possible to easily change the installation position of the equipment by only. At this time, since the equipment is connected to the ceiling equipment P via the connection pipe 62, for example, as shown in FIG. 16, the connection pipe 62 is arranged without changing the piping route of the ceiling equipment P. The position of the equipment can be changed very easily only by changing the rotation.

実施の形態にかかる天井下地構造1は、以上のように構成されている。 The ceiling base structure 1 according to the embodiment is configured as described above.

なお、以上の実施の形態においては天井裏空間Sに第1の空間S1及び第2の空間S2を形成するように天井下地構造1を構成し、第1の空間S1に対して天井裏設備Pを配設した。しかしながら、天井下地構造1の構成はこれに限定されるものではなく、例えば図17に示すように、天井裏設備Pを配設するための第1の空間S1が複数段(図示の例においては2段)に形成されてもよい。このように第1の空間S1を複数段に分けて構成することで、天井裏設備Pを設置可能なスペースを更に適切に確保できるとともに、天井下地構造1の耐震性を更に向上できる。 In the above embodiment, the ceiling base structure 1 is configured so as to form the first space S1 and the second space S2 in the attic space S, and the attic equipment P is provided for the first space S1. Was arranged. However, the configuration of the ceiling base structure 1 is not limited to this, and as shown in FIG. 17, for example, as shown in FIG. 17, the first space S1 for arranging the attic equipment P has a plurality of stages (in the illustrated example). It may be formed in two stages). By configuring the first space S1 in a plurality of stages in this way, it is possible to more appropriately secure a space in which the attic equipment P can be installed, and further improve the earthquake resistance of the ceiling base structure 1.

次に実施の形態にかかる天井下地構造1の施工方法について、図面を参照しながら説明する。 Next, the construction method of the ceiling base structure 1 according to the embodiment will be described with reference to the drawings.

天井下地構造1の施工に際しては、先ず、図18(a)に示すように天井スラブCに対して所定間隔でインサート11を埋設する。インサート11を埋設タイミングは特に限定されるものではなく、例えば天井スラブCの打設前に予め設置されてもよいし、天井スラブCの打設後に打ち込まれてもよい。 When constructing the ceiling base structure 1, first, as shown in FIG. 18A, inserts 11 are embedded in the ceiling slab C at predetermined intervals. The timing of burying the insert 11 is not particularly limited, and for example, the insert 11 may be installed in advance before the ceiling slab C is placed, or may be driven after the ceiling slab C is placed.

次に、図18(b)に示すように、天井スラブCに埋設されたインサート11に対して吊下部材10(実施の形態においては全ネジ)を垂下させる。 Next, as shown in FIG. 18B, the hanging member 10 (all screws in the embodiment) is hung from the insert 11 embedded in the ceiling slab C.

次に、図18(c)に示すように、それぞれの吊下部材10の下部に耐震接続部材20を固定する。具体的には、耐震接続部材20の上板状部材22aに形成された貫通孔24に吊下部材10を螺合させることにより、耐震接続部材20を吊下部材10に固定する。このとき、それぞれの吊下部材10に固定される耐震接続部材20は、少なくとも架橋部材30の接続口をなす筒状部材21が対向して配置されるように、それぞれの高さ位置及び向きが調整される。またこのとき、上述したように架橋部材30により接続される2つの耐震接続部材20の間で、耐震プレート23が直交して配置されるように、向きが決定される。 Next, as shown in FIG. 18C, the seismic connection member 20 is fixed to the lower part of each suspension member 10. Specifically, the seismic connection member 20 is fixed to the suspension member 10 by screwing the suspension member 10 into the through hole 24 formed in the upper plate-shaped member 22a of the seismic connection member 20. At this time, the seismic connection members 20 fixed to the respective suspension members 10 have their respective height positions and orientations so that at least the tubular members 21 forming the connection ports of the cross-linking members 30 are arranged so as to face each other. It will be adjusted. At this time, the orientation is determined so that the seismic plates 23 are arranged orthogonally between the two seismic connecting members 20 connected by the cross-linking member 30 as described above.

次に、図19(a)に示すように、吊下部材10の下部に固定された耐震接続部材20を相互に接続するように架橋部材30を架設する。架橋部材30は、例えば筒状部材21に挿通されることにより耐震接続部材20に接続される。このように架橋部材30が架設されると、天井スラブC、吊下部材10及び架橋部材30に囲まれてなる第1の空間のS1が形成される。 Next, as shown in FIG. 19A, the cross-linking member 30 is erected so as to connect the seismic connection members 20 fixed to the lower part of the suspension member 10 to each other. The cross-linking member 30 is connected to the seismic connection member 20 by being inserted into, for example, the tubular member 21. When the cross-linking member 30 is erected in this way, S1 of the first space surrounded by the ceiling slab C, the suspension member 10, and the cross-linking member 30 is formed.

次に、図19(b)に示すように、第1の空間S1に対して天井裏設備Pを配設する。天井裏設備Pは、独立して天井スラブCに吊下されることなく、例えば吊下部材10や架橋部材30に対して固定部材50により固定される。このとき、例えば天井裏設備Pに勾配を設ける必要がある場合には、図12に示したように架橋部材30と天井裏設備Pとの間にスペーサ51が設けられる。 Next, as shown in FIG. 19B, the attic equipment P is arranged with respect to the first space S1. The attic equipment P is not independently suspended from the ceiling slab C, but is fixed to, for example, the suspension member 10 or the bridge member 30 by the fixing member 50. At this time, for example, when it is necessary to provide a slope in the attic equipment P, a spacer 51 is provided between the cross-linking member 30 and the attic equipment P as shown in FIG.

次に、図19(c)に示すように、耐震接続部材20の耐震プレート23の下辺23bにパネル用枠体41を接続する。このようにパネル用枠体41が接続されると、耐震接続部材20、架橋部材30及びパネル用枠体41に囲まれてなる第2の空間のS2が形成される。 Next, as shown in FIG. 19C, the panel frame 41 is connected to the lower side 23b of the seismic plate 23 of the seismic connection member 20. When the panel frame 41 is connected in this way, S2 of a second space surrounded by the seismic connecting member 20, the cross-linking member 30, and the panel frame 41 is formed.

次に、例えば室内機60や照明器具61等の設備器具を配置する必要がある場合には、図20(a)に示すように、第2の空間のS2に対して当該設備器具が更に配置される。かかる場合、図20(b)に示すように設備器具と天井裏設備Pとが接続用配管62により接続される。 Next, when it is necessary to arrange equipment such as the indoor unit 60 and the lighting equipment 61, the equipment is further arranged with respect to S2 in the second space as shown in FIG. 20 (a). Will be done. In such a case, as shown in FIG. 20B, the equipment and the attic equipment P are connected by the connection pipe 62.

その後、図20(c)に示すように、パネル用枠体41に対して天井パネル42が取り付けられることにより、一連の天井下地構造1の施工が完了する。 After that, as shown in FIG. 20 (c), the ceiling panel 42 is attached to the panel frame 41 to complete the construction of the series of ceiling base structures 1.

実施の形態にかかる天井下地構造1は、以上のようにして施工される。 The ceiling base structure 1 according to the embodiment is constructed as described above.

なお、以上の実施の形態においては、図19(b)に示したように第1の空間S1に天井裏設備Pを配設した後、図19(c)に示したようにパネル用枠体41を接続した。しかしながら、天井下地構造1の施工手順はこれに限定されるものではなく、パネル用枠体41を耐震接続部材20の耐震プレート23の下辺23bに接続した後、天井パネル42の取付前に天井裏設備Pを配設するようにしてもよい。 In the above embodiment, after the ceiling equipment P is arranged in the first space S1 as shown in FIG. 19 (b), the panel frame is as shown in FIG. 19 (c). 41 was connected. However, the construction procedure of the ceiling base structure 1 is not limited to this, and after connecting the panel frame 41 to the lower side 23b of the seismic plate 23 of the seismic connection member 20, before mounting the ceiling panel 42, the ceiling back The equipment P may be arranged.

また、以上の実施の形態においては天井スラブCに埋設されたインサート11に対して、順次、天井下地構造1を構成する各種部材を接続した。しかしながら、例えば、予め外部で組み立てられた天井下地構造1をインサート11に接続してもよい。 Further, in the above embodiment, various members constituting the ceiling base structure 1 are sequentially connected to the insert 11 embedded in the ceiling slab C. However, for example, the ceiling base structure 1 assembled in advance may be connected to the insert 11.
