In this embodiment, the suspended ceiling structure 1 constructed by new construction or renovation inside the building will be described.
図1A及び図4に示すように、建物の構造体となる上階の床スラブの下面や梁(図示省略)には、間隔を置いて複数の吊り材としての吊りボルト11,・・・が吊り下げられる。 As shown in FIGS. 1A and 4, hanging bolts 11, ... As a plurality of hanging materials are provided on the lower surface and beams (not shown) of the floor slab on the upper floor, which is the structure of the building, at intervals. Can be hung.
そして、この吊りボルト11の下端部111に、直接、野縁固定部材2が吊り下げられる。ここで、吊りボルト11の下端部111とは、構築する天井の高さに合わせて取り付け位置が上下に調整される野縁固定部材2が固定される範囲の端部付近を指す。 Then, the field edge fixing member 2 is hung directly from the lower end portion 111 of the hanging bolt 11. Here, the lower end portion 111 of the hanging bolt 11 refers to the vicinity of the end portion of the range in which the field edge fixing member 2 whose mounting position is adjusted up and down according to the height of the ceiling to be constructed is fixed.
野縁固定部材2は、長尺状の部材で、野縁固定部材2の軸方向に間隔を置いて略直交する方向に向けて野縁部13が取り付けられることによって、天井下地(鋼製下地)が形成される。 The field edge fixing member 2 is a long member, and a ceiling base (steel base) is attached by attaching the field edge portion 13 in a direction substantially orthogonal to the field edge fixing member 2 at intervals in the axial direction. ) Is formed.
略平行に配置された複数の野縁部13,・・・の下面132側には、石こうボードなどの天井面材14が取り付けられる。この天井面材14は、天井面を形成する仕上げ材、又は仕上げ材を貼り付けるための下地板材である。 A ceiling surface material 14 such as a gypsum board is attached to the lower surface 132 side of the plurality of field edge portions 13, ... Arranged substantially in parallel. The ceiling surface material 14 is a finishing material that forms the ceiling surface, or a base plate material for attaching the finishing material.
天井面材14は、通常は複数の板材によって構成されており、図1Aでは、隣接させる板材の端縁同士が野縁固定部材2の中央位置で突き合わされた図となっている。 The ceiling surface material 14 is usually composed of a plurality of plate materials, and in FIG. 1A, the edges of the adjacent plate materials are butted against each other at the center position of the field edge fixing member 2.
本実施の形態の野縁固定部材2は、図1Aに示すように、吊りボルト11の下端部111に固定される長尺状の帯状固定部としての頂面部21及びその直上に重ねられる上板24の中央部分と、頂面部21の両側縁に接続された一対の側壁部22,22と、一対の側壁部22,22の下縁からそれぞれ外側に向けて張り出された一対の載置面部23,23と、載置面部23,23と略平行となるように張り出された上制限部241,241とによって、主に構成される。 As shown in FIG. 1A, the field edge fixing member 2 of the present embodiment has a top surface portion 21 as a long strip-shaped fixing portion fixed to the lower end portion 111 of the hanging bolt 11, and an upper plate stacked directly above the top surface portion 21. A pair of side wall portions 22, 22 connected to the central portion of 24, both side edges of the top surface portion 21, and a pair of mounting surface portions projecting outward from the lower edges of the pair of side wall portions 22, 22, respectively. It is mainly composed of 23, 23 and upper limiting portions 241, 241 overhanging so as to be substantially parallel to the mounting surface portions 23, 23.
本実施の形態では、図1A及び図2に示すように、断面視ハット形の凸金具20と、帯板状の上板24とを溶接などで接合させることによって、野縁固定部材2が製作される。 In the present embodiment, as shown in FIGS. 1A and 2, the field edge fixing member 2 is manufactured by joining the hat-shaped convex metal fitting 20 in cross-sectional view and the strip-shaped upper plate 24 by welding or the like. Will be done.
上板24は、幅方向(野縁固定部材2の軸直交方向)の中央を、凸金具20の頂面部21の幅方向の中央位置に合わせて設置される。この上板24の頂面部21の直上領域は、帯状固定部の一部として上層になる。そして、頂面部21より両側に張り出された上板24の領域が、上制限部241,241となる。 The upper plate 24 is installed so that the center in the width direction (direction orthogonal to the axis of the field edge fixing member 2) is aligned with the center position in the width direction of the top surface portion 21 of the convex metal fitting 20. The region directly above the top surface portion 21 of the upper plate 24 becomes an upper layer as a part of the strip-shaped fixing portion. Then, the area of the upper plate 24 protruding from the top surface portion 21 on both sides becomes the upper limiting portions 241,241.
一方、凸金具20は、帯状固定部の一部として下層となる頂面部21と一対の側壁部22,22と一対の載置面部23,23とが一体に形成された金具である。詳細には、側壁部22は、頂面部21の側縁から略直角に下方に向けて垂下され、載置面部23は、側壁部22の下縁から略直角に外側に向けて張り出される。 On the other hand, the convex metal fitting 20 is a metal fitting in which a top surface portion 21 as a lower layer, a pair of side wall portions 22, 22 and a pair of mounting surface portions 23, 23 are integrally formed as a part of the band-shaped fixing portion. Specifically, the side wall portion 22 hangs downward at a substantially right angle from the side edge of the top surface portion 21, and the mounting surface portion 23 projects outward at a substantially right angle from the lower edge of the side wall portion 22.
図1Bに示すように、上制限部241の張り出し量は、載置面部23の張り出し量と比べて短くなっている。載置面部23は、野縁部13の端部131を支持できる幅だけ張り出されている。上制限部241の張り出し量を載置面部23より短くすることで、上方から野縁部13の端部131を載置面部23に載せやすくすることができる。 As shown in FIG. 1B, the overhanging amount of the upper limiting portion 241 is shorter than the overhanging amount of the mounting surface portion 23. The mounting surface portion 23 is projected by a width that can support the end portion 131 of the field edge portion 13. By making the overhanging amount of the upper limiting portion 241 shorter than that of the mounting surface portion 23, it is possible to facilitate mounting the end portion 131 of the field edge portion 13 on the mounting surface portion 23 from above.
野縁固定部材2は、天井の大きさによっては非常に長尺にする必要があるため、図2に示すように、必要に応じてジョイント板26によって軸方向に継ぎ足される。 Since the field edge fixing member 2 needs to be very long depending on the size of the ceiling, it is added axially by the joint plate 26 as needed, as shown in FIG.
この図2では、軸方向に並べられた凸金具20,20の側壁部22,22間に長方形の鋼板によって形成されるジョイント板26を跨らせ、ビス材261,・・・によって接合させた例を示した。なお、野縁固定部材2の継手方法は、この例に限定されるものではない。 In FIG. 2, a joint plate 26 formed of a rectangular steel plate is straddled between the side wall portions 22 and 22 of the convex metal fittings 20 and 20 arranged in the axial direction, and the joint plates 26 are joined by screw members 261, ... An example is shown. The method of joining the field edge fixing member 2 is not limited to this example.
図1Aに示すように、上制限部241は、載置面部23から野縁部13の端部131の高さ分だけ離隔した上方位置に設けられる。すなわち、野縁部13の端部131は、載置面部23と上制限部241とによって挟まれることになる。 As shown in FIG. 1A, the upper limiting portion 241 is provided at an upper position separated by the height of the end portion 131 of the field edge portion 13 from the mounting surface portion 23. That is, the end portion 131 of the field edge portion 13 is sandwiched between the mounting surface portion 23 and the upper limiting portion 241.
載置面部23と上制限部241との間に収容された野縁部13の端部131には、天井面材14の下面から打ち込まれた接合手段としてのビス材3の先端が埋設される。 The tip of the screw material 3 as a joining means driven from the lower surface of the ceiling surface material 14 is embedded in the end 131 of the field edge portion 13 housed between the mounting surface portion 23 and the upper limiting portion 241. ..
ここで、野縁部13には、図3に示したような断面視略長方形の角形鋼管や、断面視略C字形のC形鋼などの鋼材が使用される。要するに、略平行な下面132と上面133とが形成された部材が使用される。 Here, a steel material such as a rectangular steel pipe having a substantially rectangular cross section as shown in FIG. 3 or a C-shaped steel having a substantially C-shaped cross section is used for the field edge portion 13. In short, a member in which a substantially parallel lower surface 132 and an upper surface 133 are formed is used.
一方、吊りボルト11の下端部111は、上板24及び頂面部21に貫通して設けられた穴である長穴25に通されて、上下に装着されたナット12A,12Bに締め付けられることによって、野縁固定部材2に固定される。 On the other hand, the lower end portion 111 of the hanging bolt 11 is passed through an elongated hole 25 which is a hole provided through the upper plate 24 and the top surface portion 21, and is tightened to the nuts 12A and 12B mounted vertically. , It is fixed to the field edge fixing member 2.
詳細には、図1Bに示すように、上板24及び頂面部21には、野縁固定部材2の軸方向に長い長穴25が穿孔されている。このため、吊りボルト11の下端部111の位置に対して、野縁固定部材2の位置を軸方向に微調整して固定することができる。また、吊りボルト11に対してナット12A,12Bを締め付ける高さ位置を調整することによって、天井の高さを容易に変更することができる。 Specifically, as shown in FIG. 1B, the upper plate 24 and the top surface portion 21 are perforated with an elongated hole 25 long in the axial direction of the field edge fixing member 2. Therefore, the position of the field edge fixing member 2 can be finely adjusted and fixed in the axial direction with respect to the position of the lower end portion 111 of the hanging bolt 11. Further, the height of the ceiling can be easily changed by adjusting the height position of tightening the nuts 12A and 12B with respect to the hanging bolt 11.
図3に示すように、略平行に間隔を置いて吊りボルト11,・・・から吊り下げられた野縁固定部材2,・・・に対しては、野縁固定部材2の軸方向に間隔を置いて略平行に野縁部13,・・・が架け渡される。 As shown in FIG. 3, the field edge fixing members 2, ... Suspended from the hanging bolts 11, ... At intervals substantially parallel to each other are spaced in the axial direction of the field edge fixing member 2. The field edges 13, ... Are laid in parallel with each other.
野縁部13は、両側の端部131,131がそれぞれ野縁固定部材2,2の載置面部23,23に載せられる。また、野縁部13の軸方向に連続するように、隣接する野縁部13が架け渡される。すなわち、野縁固定部材2,・・・と野縁部13,・・・とによって、格子状の鋼製下地(天井下地)が形成される。 In the field edge portion 13, the end portions 131 and 131 on both sides are mounted on the mounting surface portions 23 and 23 of the field edge fixing members 2 and 2, respectively. Further, the adjacent field edge portions 13 are bridged so as to be continuous in the axial direction of the field edge portions 13. That is, a grid-like steel base (ceiling base) is formed by the field edge fixing members 2, ... And the field edge portions 13, ....
ここで、平行に配置される野縁部13,13間であっても、補強が必要な箇所には追加野縁部15を配置することができる(図3の右側参照)。例えば、照明や天井裏設備等の別途荷重が作用する箇所には、補強のために追加野縁部15を架け渡すことができる。この追加野縁部15も、端部151はビス材3によって載置面部23に固定される。 Here, even between the field edges 13 and 13 arranged in parallel, the additional field edge 15 can be arranged at a position requiring reinforcement (see the right side of FIG. 3). For example, an additional field edge portion 15 can be laid over for reinforcement at a location where a separate load acts, such as lighting or attic equipment. The end portion 151 of the additional field edge portion 15 is also fixed to the mounting surface portion 23 by the screw material 3.
次に、本実施の形態の吊り天井構造1の構築方法について、図1A,1B及び図2−図4を参照しながら説明する。 Next, a method of constructing the suspended ceiling structure 1 of the present embodiment will be described with reference to FIGS. 1A and 1B and FIGS. 2 to 4.
まず、図2に示すように、建物の床スラブなどから吊り下げられた吊りボルト11の下端部111に、ナット12A,12Bを使用して、野縁固定部材2を固定する。 First, as shown in FIG. 2, nuts 12A and 12B are used to fix the field edge fixing member 2 to the lower end 111 of the hanging bolt 11 suspended from the floor slab of the building.
詳細には、吊りボルト11の下端部111は、ナット12Aを装着した状態で図1Bに示すように上板24及び頂面部21の長穴25に通される。このように帯状固定部に穿孔される穴を長穴25にしておくことで、1本の野縁固定部材2を複数の吊りボルト11,・・・に固定する際も、微調整によって容易に固定作業を行うことができる。 Specifically, the lower end portion 111 of the hanging bolt 11 is passed through the elongated hole 25 of the upper plate 24 and the top surface portion 21 as shown in FIG. 1B with the nut 12A attached. By making the hole to be drilled in the strip-shaped fixing portion into the elongated hole 25 in this way, even when fixing one field edge fixing member 2 to a plurality of hanging bolts 11, ..., It is easy to make fine adjustments. Can perform fixing work.
続いて図1Aに示すように、頂面部21の下方に突出された下端部111にナット12Bを装着して、工具を凸金具20の下方から挿入して締め付ける。なお、この段階では天井面材14は配置されていないので、工具を側壁部22,22間の空洞に下方から挿し込むことができる。 Subsequently, as shown in FIG. 1A, the nut 12B is attached to the lower end portion 111 projecting downward from the top surface portion 21, and the tool is inserted from below the convex metal fitting 20 and tightened. Since the ceiling surface material 14 is not arranged at this stage, the tool can be inserted into the cavity between the side wall portions 22 and 22 from below.
そして、上下のナット12A,12Bを締め付けることによって、野縁固定部材2の帯状固定部(21,24)を挟持させて、吊りボルト11に強固に野縁固定部材2を固定する。 Then, by tightening the upper and lower nuts 12A and 12B, the strip-shaped fixing portions (21, 24) of the field edge fixing member 2 are sandwiched, and the field edge fixing member 2 is firmly fixed to the hanging bolt 11.
また、天井の一辺が長い場合は、図2に示すように、軸方向が一致するように複数の野縁固定部材2,2を並べて吊り下げ、野縁固定部材2,2間をジョイント板26とビス材261,・・・とによって連結させる。 When one side of the ceiling is long, as shown in FIG. 2, a plurality of field edge fixing members 2 and 2 are hung side by side so that the axial directions match, and the joint plate 26 is connected between the field edge fixing members 2 and 2. And the screw material 261 ...
そして、図3に示すように、平行に吊り下げられた野縁固定部材2,2間に、複数の野縁部13,・・・を平行に架け渡す。すなわち野縁部13は、野縁固定部材2の軸方向に間隔を置いて配置され、両側の端部131,131は、野縁固定部材2の載置面部23に載せられる。 Then, as shown in FIG. 3, a plurality of field edge portions 13, ... Are bridged in parallel between the field edge fixing members 2, 2 suspended in parallel. That is, the field edge portions 13 are arranged at intervals in the axial direction of the field edge fixing member 2, and the end portions 131, 131 on both sides are placed on the mounting surface portion 23 of the field edge fixing member 2.
通常は、野縁部13の軸方向に連続するように隣接する野縁部13が配置され、格子状の鋼製下地が形成される。また、照明の取り付け位置など補強が必要な箇所には、追加野縁部15を配置することもできる。さらには、天井の縁部付近など異形となる箇所などでは、図示していないが、隣接する野縁部13,13の軸方向を連続させず、ずらしてもよい。 Normally, adjacent field edge portions 13 are arranged so as to be continuous in the axial direction of the field edge portion 13, and a grid-like steel base is formed. Further, the additional field edge portion 15 can be arranged at a place where reinforcement is required such as a lighting mounting position. Further, although not shown, the axial directions of the adjacent field edges 13 and 13 may be shifted without being continuous in a place having an irregular shape such as near the edge of the ceiling.
このようにして吊りボルト11,・・・に吊り下げられた天井下地となる枠組みに対しては、図4に示すように、石こうボードなどの天井面材14を下方から取り付ける。 As shown in FIG. 4, a ceiling surface material 14 such as a gypsum board is attached from below to the framework serving as the ceiling base suspended from the suspension bolts 11, ...
天井面材14は、図1Aに示すように、下方からねじ込まれたビス材3によって野縁部13に接合される。また、野縁部13の端部131においては、ビス材3は、天井面材14と載置面部23を通って野縁部13にねじ込まれる。こうして天井面材14が取り付けられることによって、建物の構造体から吊りボルト11,・・・によって吊り下げられた吊り天井構造1が完成する。 As shown in FIG. 1A, the ceiling surface material 14 is joined to the field edge portion 13 by a screw material 3 screwed from below. Further, at the end 131 of the field edge portion 13, the screw material 3 is screwed into the field edge portion 13 through the ceiling surface material 14 and the mounting surface portion 23. By attaching the ceiling surface material 14 in this way, the suspended ceiling structure 1 suspended from the structure of the building by the hanging bolts 11, ... Is completed.
次に、本実施の形態の野縁固定部材2、及びそれが取り付けられた吊り天井構造1、並びに吊り天井構造1の構築方法の作用について説明する。 Next, the operation of the field edge fixing member 2 of the present embodiment, the suspended ceiling structure 1 to which the field edge fixing member 2 is attached, and the method of constructing the suspended ceiling structure 1 will be described.
このように構成された本実施の形態の野縁固定部材2は、建物の構造体から吊り下げられた吊りボルト11に野縁固定部材2の頂面部21を固定し、その頂面部21に接続される一対の側壁部22,22から張り出される載置面部23,23に、野縁部13の端部131,131を載せる。 The field edge fixing member 2 of the present embodiment configured in this way fixes the top surface portion 21 of the field edge fixing member 2 to a hanging bolt 11 suspended from the structure of the building and connects to the top surface portion 21. The end portions 131, 131 of the field edge portion 13 are placed on the mounting surface portions 23, 23 overhanging from the pair of side wall portions 22, 22.
この載置面部23に対しては、野縁部13の高さ分だけ離隔した上方位置に上制限部241が張り出されており、野縁部13の端部131は、載置面部23と上制限部241とに挟まれることになる。 An upper limiting portion 241 is projected from the mounting surface portion 23 at an upper position separated by the height of the field edge portion 13, and the end portion 131 of the field edge portion 13 is separated from the mounting surface portion 23. It will be sandwiched between the upper limiting portion 241.
このように吊りボルト11に直接取り付けられる野縁固定部材2に、野縁部13の端部131を直接受けさせる構成となっているため、吊りハンガーや野縁受け部やクリップなどを介して野縁が支持される場合と比べて、必要部品数を少なくすることができる。また、必要部品数が削減されることで、吊り天井構造1を軽量化することができる。 Since the field edge fixing member 2 directly attached to the hanging bolt 11 is configured to directly receive the end portion 131 of the field edge portion 13, the field edge receiving portion, a clip, or the like is used to directly receive the field edge portion 131. The number of required parts can be reduced as compared with the case where the edge is supported. Further, by reducing the number of required parts, the weight of the suspended ceiling structure 1 can be reduced.
さらに、引っ掛けるだけの吊りハンガーや嵌めるだけのクリップを使用した場合は、地震などの外力の影響により吊りハンガーやクリップが外れて天井下地が脱落するおそれもあるが、本実施の形態の野縁固定部材2のようにナット12A,12Bによって吊りボルト11に固定され、ビス材3によって野縁部13が接合される構成であれば、脱落の発生を低減することができる。 Furthermore, if a hanging hanger that can only be hooked or a clip that can be fitted is used, the hanging hanger or clip may come off due to the influence of an external force such as an earthquake, and the ceiling base may fall off. If the structure is such that the suspension bolts 11 are fixed by the nuts 12A and 12B and the field edge portion 13 is joined by the screw material 3 as in the member 2, the occurrence of falling off can be reduced.
また、上制限部241が載置面部23の上方に連続して設けられていれば、野縁部13を野縁固定部材2の軸方向のいずれの位置にも自由に配置することができる。 Further, if the upper limiting portion 241 is continuously provided above the mounting surface portion 23, the field edge portion 13 can be freely arranged at any position in the axial direction of the field edge fixing member 2.
例えば、照明や天井裏設備等が配置される箇所は、荷重が大きくなり補強が必要となるため、通常の野縁部13,・・・に加えて追加野縁部15を配置することが容易にできる。すなわち、追加野縁部15の端部を、補強したい位置の載置面部23に載せて、ビス材3によって固定すれば良い。 For example, in places where lighting, attic equipment, etc. are placed, the load becomes large and reinforcement is required, so it is easy to place additional field edges 15 in addition to the normal field edges 13, ... Can be done. That is, the end portion of the additional field edge portion 15 may be placed on the mounting surface portion 23 at the position to be reinforced and fixed by the screw material 3.
要するに、野縁部13又は追加野縁部15は、載置面部23の上に上制限部241が設けられている箇所であれば、どこにでも設置して下からビス材3で固定することができるので、野縁部13,・・・の配置パターンを自由に設定することができる。 In short, the field edge portion 13 or the additional field edge portion 15 can be installed anywhere where the upper limiting portion 241 is provided on the mounting surface portion 23 and fixed with the screw material 3 from below. Therefore, the arrangement pattern of the field edges 13, ... Can be freely set.
さらに、頂面部21と一対の側壁部22,22と一対の載置面部23,23とが断面視ハット形の一体に形成された凸金具20は、剛性が高いうえに、簡単に高い精度で製作することができる。すなわち、頂面部21と側壁部22と載置面部23との相対的な位置関係を固定できるので、製作がし易く、高い精度で仕上げることができる。 Further, the convex metal fitting 20 in which the top surface portion 21, the pair of side wall portions 22, 22 and the pair of mounting surface portions 23, 23 are integrally formed in a hat shape in cross-sectional view has high rigidity and is easily and highly accurate. Can be manufactured. That is, since the relative positional relationship between the top surface portion 21, the side wall portion 22, and the mounting surface portion 23 can be fixed, it is easy to manufacture and can be finished with high accuracy.
また、上板24及び頂面部21に吊りボルト11の下端部111を挿通させる長穴25が設けられていれば、吊りボルト11の位置と野縁固定部材2との位置調整を容易に行うことができ、施工性に優れている。 Further, if the upper plate 24 and the top surface portion 21 are provided with an elongated hole 25 through which the lower end portion 111 of the suspension bolt 11 is inserted, the position of the suspension bolt 11 and the position of the field edge fixing member 2 can be easily adjusted. And has excellent workability.
そして、野縁固定部材2を使用した吊り天井構造1の構築方法の発明では、両端が野縁固定部材2に挿し込まれた野縁部13に対して載置面部23の下方からビス材3をねじ込んだときに、野縁部13が浮き上がろうとしても上制限部241で上面133が抑えられるため、容易に接合作業や天井面材14の取り付け作業を行うことができる。 Then, in the invention of the method of constructing the suspended ceiling structure 1 using the field edge fixing member 2, the screw material 3 is formed from below the mounting surface portion 23 with respect to the field edge portion 13 whose both ends are inserted into the field edge fixing member 2. Even if the field edge portion 13 tries to rise when the screw is screwed in, the upper limit portion 241 suppresses the upper surface 133, so that the joining work and the attachment work of the ceiling surface material 14 can be easily performed.
以下、前記実施の形態で説明した野縁固定部材2とは別の形態の実施例1の野縁固定部材2Aについて、図5を参照しながら説明する。なお、前記実施の形態で説明した内容と同一乃至均等な部分の説明については、同一用語又は同一符号を用いて説明する。 Hereinafter, the field edge fixing member 2A of the first embodiment, which is different from the field edge fixing member 2 described in the above embodiment, will be described with reference to FIG. The same or equivalent parts as those described in the above-described embodiment will be described using the same terms or the same reference numerals.
前記実施の形態では、凸金具20と同じ軸方向の長さの帯板状の上板24が頂面部21に接合された野縁固定部材2について説明した。本実施例1では、上制限部が間隔を置いて設けられる場合について説明する。 In the above-described embodiment, the field edge fixing member 2 in which the strip-shaped upper plate 24 having the same axial length as the convex metal fitting 20 is joined to the top surface portion 21 has been described. In the first embodiment, a case where the upper limiting portions are provided at intervals will be described.
ここで、上制限部は、載置面部23に設置された野縁部13の端部131が、下方からねじ込まれたビス材3の力によって浮き上がらないようにするためのストッパ機能を発揮させるために設置される。 Here, the upper limiting portion is for exerting a stopper function for preventing the end portion 131 of the field edge portion 13 installed on the mounting surface portion 23 from being lifted by the force of the screw material 3 screwed from below. Will be installed in.
このため、野縁部13又は追加野縁部15が設置されない箇所には不要となるため、野縁部13又は追加野縁部15の設置が想定される位置にのみ設けることで、軽量化された野縁固定部材2Aにすることができる。 Therefore, it is not necessary in the place where the field edge portion 13 or the additional field edge portion 15 is not installed. Therefore, the weight can be reduced by providing the field edge portion 13 or the additional field edge portion 15 only at the position where the installation is expected. It can be a field edge fixing member 2A.
詳細には、長方形の矩形板24Aを、頂面部21の軸方向に間隔を置いて接合させる。この矩形板24Aの頂面部21から幅方向(軸直交方向)に張り出された両側の領域が、上制限部241A,241Aとなる。 Specifically, the rectangular rectangular plates 24A are joined at intervals in the axial direction of the top surface portion 21. The regions on both sides of the rectangular plate 24A projecting from the top surface portion 21 in the width direction (axis orthogonal direction) are the upper limiting portions 241A and 241A.
要するに、上制限部241A,241Aを、野縁部13又は追加野縁部15の設置が想定される位置に間隔を置いて設ける。例えば、野縁固定部材2Aの軸方向の長さが200mm程度の矩形板24Aを、200mmの間隔で設置していけば、野縁部13,13の間隔が300mm,600mm,900mmなど様々な間隔に適用することができる。 In short, the upper limiting portions 241A and 241A are provided at intervals at positions where the field edge portion 13 or the additional field edge portion 15 is expected to be installed. For example, if rectangular plates 24A having an axial length of about 200 mm of the field edge fixing member 2A are installed at intervals of 200 mm, the intervals of the field edge portions 13 and 13 are various such as 300 mm, 600 mm, and 900 mm. Can be applied to.
このような構成にすることによって、上制限部241Aの面積が大幅に削減できる。すなわち、前記実施の形態で説明した帯板状の上板24を、間隔を置いて設けられる矩形板24A,・・・に置き換えることができ、軽量化を図ることが可能になる。 With such a configuration, the area of the upper limiting portion 241A can be significantly reduced. That is, the strip-shaped upper plate 24 described in the above embodiment can be replaced with rectangular plates 24A, ... Provided at intervals, and the weight can be reduced.
なお、実施例1のこの他の構成及び作用効果については、前記実施の形態又は他の実施例と略同様であるため説明を省略する。 Since the other configurations and effects of Example 1 are substantially the same as those of the above-described embodiment or other examples, description thereof will be omitted.
以下、前記実施の形態及び実施例1で説明した野縁固定部材2,2Aとは別の形態の実施例2の野縁固定部材2B,2Cについて、図6,7を参照しながら説明する。なお、前記実施の形態又は実施例1で説明した内容と同一乃至均等な部分の説明については、同一用語又は同一符号を用いて説明する。 Hereinafter, the field edge fixing members 2B and 2C of the second embodiment different from the field edge fixing members 2 and 2A described in the above embodiment and the first embodiment will be described with reference to FIGS. 6 and 7. The same or equivalent parts as those described in the above-described embodiment or the first embodiment will be described using the same terms or the same reference numerals.
前記実施の形態又は実施例1では、頂面部21の上面に上板24又は矩形板24Aを取り付けることによって上制限部241,241Aを設ける場合について説明した。 In the above-described embodiment or the first embodiment, a case where the upper limiting portion 241,241A is provided by attaching the upper plate 24 or the rectangular plate 24A to the upper surface of the top surface portion 21 has been described.
本実施例2では、帯状固定部21B,21Cの高さと上制限部の高さとが異なっている場合について説明する。図6は、帯状固定部21Bの高さが、上制限部となる上フランジ27,27よりも高い位置に設けられた野縁固定部材2Bの構成を示している。 In the second embodiment, a case where the heights of the strip-shaped fixing portions 21B and 21C and the height of the upper limiting portion are different will be described. FIG. 6 shows the configuration of the field edge fixing member 2B provided at a position where the height of the strip-shaped fixing portion 21B is higher than the upper flanges 27 and 27 which are the upper limiting portions.
この野縁固定部材2Bは、吊りボルト11の下端部111に固定される長尺状の帯状固定部21Bと、帯状固定部21Bの両側縁に接続された一対の側壁部22B,22Bと、一対の側壁部22B,22Bの下縁からそれぞれ外側に向けて張り出された一対の載置面部23B,23Bと、載置面部23B,23Bと略平行となるように張り出された上フランジ27,27とによって、主に構成される。 The field edge fixing member 2B includes a long strip-shaped fixing portion 21B fixed to the lower end portion 111 of the hanging bolt 11 and a pair of side wall portions 22B and 22B connected to both side edges of the strip-shaped fixing portion 21B. A pair of mounting surface portions 23B and 23B projecting outward from the lower edges of the side wall portions 22B and 22B, respectively, and an upper flange 27 extending so as to be substantially parallel to the mounting surface portions 23B and 23B. It is mainly composed of 27.
この上フランジ27は、載置面部23Bの上方位置の側壁部22Bの途中から略直角に外側に向けて張り出される。この上フランジ27の張り出し量は、載置面部23Bの張り出し量と比べて短くなっている。 The upper flange 27 projects outward at a substantially right angle from the middle of the side wall portion 22B located above the mounting surface portion 23B. The overhanging amount of the upper flange 27 is shorter than the overhanging amount of the mounting surface portion 23B.
一方、図7は、帯状固定部21Cの高さが、上制限部となる上フランジ28,28よりも低い位置に設けられた野縁固定部材2Cの構成を示している。 On the other hand, FIG. 7 shows the configuration of the field edge fixing member 2C provided at a position where the height of the band-shaped fixing portion 21C is lower than the upper flanges 28 and 28 which are the upper limiting portions.
この野縁固定部材2Cは、吊りボルト11の下端部111に固定される長尺状の帯状固定部21Cと、帯状固定部21Cの両側縁に接続された一対の側壁部22C,22Cと、一対の側壁部22C,22Cの下縁からそれぞれ外側に向けて張り出された一対の載置面部23C,23Cと、載置面部23C,23Cと略平行となるように張り出された上フランジ28,28とによって、主に構成される。 The field edge fixing member 2C includes a long strip-shaped fixing portion 21C fixed to the lower end portion 111 of the hanging bolt 11 and a pair of side wall portions 22C and 22C connected to both side edges of the strip-shaped fixing portion 21C. A pair of mounting surface portions 23C, 23C projecting outward from the lower edges of the side wall portions 22C, 22C, and an upper flange 28, projecting so as to be substantially parallel to the mounting surface portions 23C, 23C. It is mainly composed of 28.
この帯状固定部21Cは、側壁部22C,22Cの途中に架け渡される。また、上フランジ28は、側壁部22Cの上縁から略直角に外側に向けて張り出される。この上フランジ28の張り出し量は、載置面部23Cの張り出し量と比べて短くなっている。 The band-shaped fixing portion 21C is bridged in the middle of the side wall portions 22C and 22C. Further, the upper flange 28 projects outward at a substantially right angle from the upper edge of the side wall portion 22C. The overhanging amount of the upper flange 28 is shorter than the overhanging amount of the mounting surface portion 23C.
このように野縁固定部材2B,2Cにおいては、帯状固定部21B,21Cと上制限部となる上フランジ27,28との位置関係を、自由に調整することができる。 In this way, in the field edge fixing members 2B and 2C, the positional relationship between the strip-shaped fixing portions 21B and 21C and the upper flanges 27 and 28 serving as the upper limiting portions can be freely adjusted.
帯状固定部21B,21Cの相対的な位置を高さ方向で変更することで、野縁固定部材2B,2Cの部材高さを調整することができる。また、野縁固定部材2Bの構成であれば、他の部材と比べて吊りボルト11の下端部111の突出量を長くできるので、天井高さの調整範囲を広げることができる。 By changing the relative positions of the strip-shaped fixing portions 21B and 21C in the height direction, the member heights of the field edge fixing members 2B and 2C can be adjusted. Further, in the case of the configuration of the field edge fixing member 2B, the protrusion amount of the lower end portion 111 of the suspension bolt 11 can be made longer than that of other members, so that the adjustment range of the ceiling height can be widened.
一方、野縁固定部材2Cであれば、他の部材と比べて部材高さを低く抑えることができるので、天井裏空間に高さ方向の余裕がない場合にも適用することが可能である。 On the other hand, if the field edge fixing member 2C is used, the height of the member can be suppressed to be lower than that of other members, so that it can be applied even when there is no room in the ceiling space in the height direction.
また、帯状固定部21B(21C)と一対の側壁部22B,22B(22C,22C)と一対の載置面部23B,23B(23C,23C)と上フランジ27,27(28,28)とを一体に成形することで、剛性の高い部材とすることができる。 Further, the band-shaped fixing portion 21B (21C), the pair of side wall portions 22B, 22B (22C, 22C), the pair of mounting surface portions 23B, 23B (23C, 23C), and the upper flanges 27, 27 (28, 28) are integrated. By molding it into a member, it can be made into a highly rigid member.
なお、実施例2のこの他の構成及び作用効果については、前記実施の形態又は他の実施例と略同様であるため説明を省略する。 The other configurations and effects of Example 2 are substantially the same as those of the above-described embodiment or other examples, and thus the description thereof will be omitted.
