A gate-shaped horizontal member fixing portion along the upper portion and the side portion of the horizontal member, and a ceiling base material fixing portion positioned below the horizontal member fixing portion, wherein the horizontal member fixing portion includes a horizontal plate portion placed on the horizontal member and hanging plate portions hanging from both ends of the horizontal member, and the horizontal member is supported by the horizontal plate portion and the hanging plate portion. The ceiling base material fixing portion is a pair of fixing flange portions that are continuous with the lower ends of the hanging plate portions of the horizontal member fixing portion. and the ceiling base material is bridged between the pair of fixed flange portions.

このような構成の支持部材によれば、複数の長尺材を一体的に固定することができるので、曲げ応力に対して大きい断面で対抗できる横架材を形成することができる。よって、天井構造の耐震性能を高めることができる。 With the support member having such a configuration, a plurality of elongated members can be integrally fixed, so that a horizontal member that can withstand bending stress with a large cross section can be formed. Therefore, the seismic performance of the ceiling structure can be enhanced.

次に前記構成の天井構造１を施工する手順を説明しながら、かかる天井構造１および支持装置５０の作用効果を説明する。 Next, while explaining the procedure for constructing the ceiling structure 1 having the configuration described above, the effects of the ceiling structure 1 and the support device 50 will be explained.

かかる天井構造１を構築するには、まず、図２および図４に示すように、廊下２の互いに対向する壁面上部に、ランナー５を配設しビス止め（図２の（ｂ）参照）する。ランナー５は、廊下２の長手方向に沿って延在し、断面コ字状の開口部が対向するランナー５の開口部と向き合うように取り付ける。 In order to construct such a ceiling structure 1, first, as shown in FIGS. 2 and 4, runners 5 are arranged and screwed (see (b) of FIG. 2) on the upper walls of the corridor 2 facing each other. . The runners 5 extend along the longitudinal direction of the corridor 2 and are attached so that the openings of the U-shaped cross section face the openings of the opposing runners 5 .

その後、横架材１０を互いに対向するランナー５，５間に掛け渡す。横架材１０は、二本の長尺材１１の断面コ字状の側部開口部同士が互いに対向するように沿わせた状態で掛け渡す。そして、二本の長尺材１１，１１のうち一本の長尺材１１の一端部を、一方の壁３のランナー５にビス止めし、他方の長尺材１１の他端部を、他方の壁３のランナー５にビス止めする。 After that, the horizontal member 10 is stretched between the runners 5, 5 facing each other. The horizontal member 10 spans the two elongated members 11 in such a manner that the side openings of the U-shaped cross section face each other. One end of one of the two elongated members 11, 11 is screwed to the runner 5 of one wall 3, and the other end of the other elongated member 11 is screwed to the other. screw to the runner 5 of the wall 3 of .

二本の長尺材１１，１１からなる横架材１０の両端部を、支持部材３０で囲って挟持する。具体的には、門型の横架材固定部３１で、横架材１０の上面および側面を囲うことで、二本の長尺材１１，１１を固定している。さらに、支持部材３０の下部の天井下地材固定部３２に、天井下地受部材２４を固定することで、天井下地受部材２４で横架材１０の下面を覆っている。これによって、二本の長尺材１１，１１は、上下左右の全周に渡って囲まれることになるので、互いに離間することがない。また、二本の長尺材１１は、互いに固定はされていないので、長手方向に沿ってスライド可能となっている。つまり、横架材１０は、二本の長尺材１１，１１がスライドすることで、伸長することとなる。 Both ends of a horizontal member 10 composed of two elongated members 11, 11 are surrounded by supporting members 30 and sandwiched. Specifically, the two elongated members 11 and 11 are fixed by surrounding the upper surface and the side surface of the horizontal member 10 with the gate-shaped horizontal member fixing portion 31 . Further, the lower surface of the horizontal member 10 is covered with the ceiling base receiving member 24 by fixing the ceiling base receiving member 24 to the ceiling base material fixing portion 32 at the bottom of the support member 30 . As a result, the two elongated members 11, 11 are surrounded over the entire peripheries of the upper, lower, right, and left sides, so that they are not separated from each other. Moreover, since the two elongated members 11 are not fixed to each other, they are slidable along the longitudinal direction. That is, the horizontal member 10 is elongated by sliding the two long members 11 , 11 .

このような横架材１０によれば、地震時に壁３，３の距離が大きくなった際に、一方の長尺材１１は一方の壁３に固定された状態で引っ張られ、他方の長尺材１１は、他方の壁３に固定された状態で引っ張られる。そして、二本の長尺材１１，１１は互いにスライドする。このように、二本の長尺材１１，１１が壁３，３に追従してスライドすることで、横架材１０の固定部の破損を防止できるとともに、横架材１０の壁３からの離脱を防止できる。 According to such a horizontal member 10, when the distance between the walls 3, 3 increases during an earthquake, one long member 11 is pulled while being fixed to one wall 3, and the other long member 11 is pulled. The material 11 is pulled while being fixed to the other wall 3 . The two elongated members 11, 11 then slide relative to each other. In this way, the two elongated members 11, 11 slide following the walls 3, 3, so that the fixed portion of the horizontal member 10 can be prevented from being damaged, and the horizontal member 10 from the wall 3 can be prevented from being damaged. can prevent detachment.

また、横架材１０は、二本の長尺材１１，１１を沿わせて、支持部材３０と天井下地受部材２４とで囲って構成したことで、曲げ応力に対して大きい断面で対抗できる横架材を得ることができる。よって、天井構造１の耐震性能を高めることができる。さらに、長尺材１１は、断面コ字状のスタッドにて構成されており、二本の長尺材１１，１１を、側部開口部同士が互いに対向するように組み合わせているので、横架材１０が筒型形状となり、剛性を大きくすることができる。したがって、天井構造１の耐震性能をより一層高めることができる。 In addition, the horizontal member 10 is constructed by enclosing the two elongated members 11, 11 along each other and surrounded by the support member 30 and the ceiling base receiving member 24, so that the bending stress can be resisted with a large cross section. A horizontal member can be obtained. Therefore, the seismic performance of the ceiling structure 1 can be enhanced. Furthermore, the elongated member 11 is composed of a stud with a U-shaped cross section, and the two elongated members 11, 11 are combined so that the side openings are opposed to each other, so that it is horizontally mounted. The material 10 has a cylindrical shape, and can increase its rigidity. Therefore, the seismic performance of the ceiling structure 1 can be further enhanced.

さらに、本実施形態では、ランナー５を介して、横架材１０を壁３に固定しているので、横架材１０の壁３への固定作業が行い易くなる。 Furthermore, in this embodiment, since the horizontal members 10 are fixed to the wall 3 via the runners 5, the operation of fixing the horizontal members 10 to the wall 3 is facilitated.

また、門型形状の支持部材３０を介して、二本の長尺材１１，１１を固定することで、複数の長尺材１１，１１を一体的に固定することができるので、曲げ応力に対して大きい断面で対抗できる横架材１０を形成することができる。 In addition, by fixing the two elongated members 11, 11 via the gate-shaped support member 30, the plurality of elongated members 11, 11 can be integrally fixed. It is possible to form a horizontal member 10 that can counteract with a large cross section.

次に、支持装置５０を用いて、天井板支持部材２３を天井下地受部材２４に固定する。まず、図８に示すように、第一部材５１を、天井下地受部材２４に係止する。具体的には、第一部材５１を天井下地受部材２４の背面側（Ｃ形形状の外側）から移動させて、係止板部５３を上側の横板部２６ｂの上に載置する。このとき、リップ部５７が上側の横板部２６ｂの先端に掛け止められるので、第一部材５１は、天井下地受部材２４から離間することなく仮固定される。そして、天井板支持部材２３の上フランジ部２５ｂを、天井板支持部材固定部６１の切欠部６２に挿入して係止させる。 Next, the support device 50 is used to fix the ceiling board support member 23 to the ceiling base support member 24 . First, as shown in FIG. 8 , the first member 51 is locked to the ceiling base receiving member 24 . Specifically, the first member 51 is moved from the back side (the outside of the C shape) of the ceiling base receiving member 24, and the locking plate portion 53 is placed on the upper horizontal plate portion 26b. At this time, since the lip portion 57 is hooked to the tip of the upper horizontal plate portion 26b, the first member 51 is temporarily fixed without being separated from the ceiling base support member 24. As shown in FIG. Then, the upper flange portion 25b of the ceiling plate support member 23 is inserted into the notch portion 62 of the ceiling plate support member fixing portion 61 and locked.

その後、図９に示すように、第二部材５２を、天井下地受部材２４の腹面側（Ｃ形形状の内側）から移動させて、第一部材５１に取り付ける。このとき、第一部材５１は、天井下地受部材２４に仮止めされ、天井板支持部材２３は、第一部材５１に係止されて仮止めされているので、第二部材５２の設置作業が行い易い。第二部材５２の設置作業としては、まず、第二部材５２の上部切欠部７０と下部切欠部７１に、天井下地受部材２４の上下の横板部２６ｂ，２６ｃを挿入させるようにする。上部切欠部７０には、上側の横板部２６ｂと係止板部５３とが挿入する。係止片５８の突出部分５８ａの先端部は、先端に向かうに連れて斜め上方に傾斜して立ち上がっているため、上部切欠部７０の上側の枠部７０ａは、突出部分５８ａを下方に押し下げつつ、突出部分５８ａの表面に摺動しながら移動する。枠部７０ａが奥まで入り込むと、突出部分５８ａの先端が水平板部５６ａの表面よりも上方に突出して、枠部７０ａの側面に係止される。これによって、第二部材５２が第一部材５１に固定される。さらに、係止片５８の外側部分をペンチ等の工具を用いて下方に下げることで、突出部分５８ａの先端部が上方に傾斜して飛び出すので、枠部７０ａを確実に係止することができる。なお、第二部材５２を第一部材５１から取り外す場合は、係止片５８の外側部分を上方に上げることで、突出部分５８ａの先端部を下方に押し下げれば、取外し作業を容易に行うことができる。 Then, as shown in FIG. 9, the second member 52 is attached to the first member 51 by moving it from the ventral surface side (inside of the C-shape) of the ceiling base receiving member 24 . At this time, the first member 51 is temporarily fixed to the ceiling base support member 24, and the ceiling board support member 23 is temporarily fixed by being locked to the first member 51, so that the second member 52 can be installed. Easy to do. As the installation work of the second member 52 , first, the upper and lower horizontal plate portions 26 b and 26 c of the ceiling base support member 24 are inserted into the upper cutout portion 70 and the lower cutout portion 71 of the second member 52 . The upper lateral plate portion 26 b and the locking plate portion 53 are inserted into the upper notch portion 70 . Since the tip of the protruding portion 58a of the locking piece 58 is inclined upward toward the tip, the upper frame portion 70a of the upper notch 70 pushes down the protruding portion 58a. , slides on the surface of the projecting portion 58a. When the frame portion 70a is fully inserted, the tip of the protruding portion 58a protrudes above the surface of the horizontal plate portion 56a and is engaged with the side surface of the frame portion 70a. The second member 52 is thereby fixed to the first member 51 . Furthermore, by lowering the outer portion of the locking piece 58 using a tool such as pliers, the tip of the projecting portion 58a tilts upward and pops out, so that the frame portion 70a can be securely locked. . When the second member 52 is removed from the first member 51, the removal work can be easily performed by lifting the outer portion of the locking piece 58 upward and pushing down the tip of the projecting portion 58a. can be done.

第二部材５２を第一部材５１に取り付けると、第二縦板当接部６４が天井下地受部材２４の縦板部２６ａの側面に当接する。これによって、縦板部２６ａが、第一部材５１の第一縦板当接部５４と第二部材５２の第二縦板当接部６４とで挟持される。そして、第一縦板当接部５４と縦板部２６ａと第二縦板当接部６４を、ビスＶによって固定する。 When the second member 52 is attached to the first member 51 , the second vertical plate contact portion 64 contacts the side surface of the vertical plate portion 26 a of the ceiling base support member 24 . As a result, the vertical plate portion 26 a is sandwiched between the first vertical plate contact portion 54 of the first member 51 and the second vertical plate contact portion 64 of the second member 52 . Then, the first vertical plate contact portion 54, the vertical plate portion 26a, and the second vertical plate contact portion 64 are fixed with screws V. As shown in FIG.

他方、第二部材５２の天井板支持部材固定部７２の切欠部７３に天井板支持部材２３の上フランジ部２５ｂが入り込むとともに、第二部材５２の第二ウエブ当接部６５が天井板支持部材２３のウエブ部２５ａの側面に当接する。これによって、ウエブ部２５ａが、第一部材５１の第一ウエブ当接部５５と第二部材５２の第二ウエブ当接部６５とで挟持される。そして、第一ウエブ当接部５５とウエブ部２５ａと第二ウエブ当接部６５とを、ビスＶによって固定する。 On the other hand, the upper flange portion 25b of the ceiling plate support member 23 enters the notch portion 73 of the ceiling plate support member fixing portion 72 of the second member 52, and the second web contact portion 65 of the second member 52 is attached to the ceiling plate support member. 23 comes into contact with the side surface of the web portion 25a. As a result, the web portion 25 a is sandwiched between the first web contact portion 55 of the first member 51 and the second web contact portion 65 of the second member 52 . Then, the first web contact portion 55, the web portion 25a, and the second web contact portion 65 are fixed with screws V. As shown in FIG.

以上のように、支持装置５０を用いて、天井板支持部材２３と天井下地受部材２４を固定すれば、天井下地受部材２４の縦板部２６ａは、第一部材５１の第一縦板当接部５４と第二部材５２の第二縦板当接部６４とで挟持される。これによって、第一縦板当接部５４と縦板部２６ａと第二縦板当接部６４とが三枚重なって一体化されるので、天井下地受部材２４と支持装置５０との固定強度が大きくなるとともに、各部材が変形し難い。 As described above, if the ceiling plate support member 23 and the ceiling base support member 24 are fixed using the support device 50, the vertical plate portion 26a of the ceiling base support member 24 will contact the first vertical plate of the first member 51. It is sandwiched between the contact portion 54 and the second vertical plate contact portion 64 of the second member 52 . As a result, the first vertical plate contacting portion 54, the vertical plate portion 26a, and the second vertical plate contacting portion 64 are integrated in three layers, so that the fixing strength between the ceiling base support member 24 and the support device 50 is increased. becomes larger, each member is less likely to deform.

他方、天井板支持部材２３のウエブ部２５ａは、第一部材５１の第一ウエブ当接部５５と第二部材５２の第二ウエブ当接部６５とで挟持される。これによって、第一ウエブ当接部５５とウエブ部２５ａと第二ウエブ当接部６５とが三枚重なって一体化されるので、天井板支持部材２３と支持装置５０との固定強度が大きくなるとともに、各部材が変形し難い。 On the other hand, the web portion 25 a of the ceiling plate support member 23 is sandwiched between the first web contact portion 55 of the first member 51 and the second web contact portion 65 of the second member 52 . As a result, the first web contact portion 55, the web portion 25a, and the second web contact portion 65 are three-layered and integrated, so that the fixing strength between the ceiling plate support member 23 and the support device 50 is increased. In addition, each member is difficult to deform.

したがって、天井下地受部材２４と天井板支持部材２３の固定強度が大きくなるので、天井構造１の耐震性能が高くなる。また、天井下地受部材２４と天井板支持部材２３の位置関係がずれることはない。これによって、天井板２１と天井板支持部材２３がずれ難くなる。 Therefore, since the fixing strength between the ceiling base support member 24 and the ceiling board support member 23 is increased, the seismic performance of the ceiling structure 1 is improved. Further, the positional relationship between the ceiling base support member 24 and the ceiling panel support member 23 is not shifted. This makes it difficult for the ceiling plate 21 and the ceiling plate support member 23 to be displaced.

さらに、かかる支持装置５０においては、天井板支持部材２３を天井下地受部材２４に固定する際に、上フランジ部２５ｂを切欠部６２に挿入して係止することで、天井板支持部材２３を第一部材５１に仮固定して第二部材を取り付けることができる。したがって、施工が行い易い。 Further, in the support device 50, when fixing the ceiling plate support member 23 to the ceiling base support member 24, the upper flange portion 25b is inserted into the notch portion 62 and locked, so that the ceiling plate support member 23 is fixed. The second member can be attached by temporarily fixing to the first member 51 . Therefore, construction is easy.

また、かかる支持装置５０においては、天井下地受部材２４の上側の横板部２６ｂと第一部材５１の係止板部５３が、第二部材５２の上部切欠部７０に挿入され、下側の横板部２６ｃが第二部材５２の下部切欠部７１に挿入される。つまり、第二部材５２が天井下地受部材２４に噛み合う構成となるので、支持装置５０と天井下地受部材２４との固定強度がより一層大きくなる。 Further, in the support device 50, the upper side plate portion 26b of the ceiling base support member 24 and the locking plate portion 53 of the first member 51 are inserted into the upper notch portion 70 of the second member 52, and the lower side plate portion 26b The horizontal plate portion 26 c is inserted into the lower notch portion 71 of the second member 52 . That is, since the second member 52 is configured to mesh with the ceiling base support member 24, the fixing strength between the support device 50 and the ceiling base support member 24 is further increased.

さらに、かかる天井構造１では、天井板支持部材２３の下フランジ部２５ｃが、天井板２１の外周側面に形成された凹溝２２に嵌合されているので、天井板２１の固定強度が大きい。また、天井板支持部材２３は廊下幅方向に延在しており、廊下長手方向に揺れる地震が発生した際には、隣り合う天井板２１，２１が、下フランジ部２５ｃに直交する方向に揺れる。このとき、天井板２１，２１は、下フランジ部２５ｃを挟んで天井板支持部材２３と一体化されているので、天井板支持部材２３から外れ難い。廊下幅方向に揺れる地震が発生した際には、天井板２１と天井板支持部材２３は、ともに壁３に当接して揺れが抑えられるので、天井板２１は天井板支持部材２３から外れ難い。 Furthermore, in the ceiling structure 1, since the lower flange portion 25c of the ceiling plate support member 23 is fitted into the groove 22 formed on the outer peripheral side surface of the ceiling plate 21, the fixing strength of the ceiling plate 21 is high. Further, the ceiling plate support member 23 extends in the width direction of the corridor, and when an earthquake occurs that shakes in the longitudinal direction of the corridor, the adjacent ceiling plates 21, 21 shake in the direction perpendicular to the lower flange portion 25c. . At this time, since the ceiling plates 21, 21 are integrated with the ceiling plate support member 23 with the lower flange portion 25c interposed therebetween, they are unlikely to come off from the ceiling plate support member 23. When an earthquake swaying in the width direction of the corridor occurs, both the ceiling plate 21 and the ceiling plate support member 23 abut on the wall 3 to suppress the shaking, so that the ceiling plate 21 is hard to come off from the ceiling plate support member 23.例文帳に追加
