Description

本発明は、天井部の野縁材等の揺れを保護する天井の下地構造に関する。 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a base structure for a ceiling that protects the joists of the ceiling from shaking.

従来、地震時等による建物の天井部の揺れに対し、これに対処するための天井構造が知られている。 2. Description of the Related Art Conventionally, there is known a ceiling structure for coping with shaking of a building ceiling caused by an earthquake or the like.

例えば、図７に示すように、特許文献１に記載の吊り天井の回り縁構造は、天井下地材と天井板材６０の各側端部をそれぞれ被覆する第1見切材６２、及びその上端との係合により側壁と天井板材６０の間の空間を覆って側壁に沿って延在する第1目隠部材６４等を備え、仮に、吊り天井が横揺れして天井板材６０が側壁Ｗ方向に動いたときには、第１見切り材６２が第１目隠部材６４の下面に沿って側壁Ｗに向けて移動し、天井板材６０が側壁Ｗから離れる方向に動いたときには、爪部６６が鉤部６８に係合し第1見切材６２が傾斜するとともに後方に移動する。これにより、地震によって吊り天井が揺れたとき、天井下地材と天井板材６０が当該建造物の側壁に衝突して破損し、落下するのを防止するというものである。 For example, as shown in FIG. 7, the peripheral structure of the suspended ceiling described in Patent Document 1 includes a first parting member 62 covering each side end of the ceiling base member and the ceiling plate member 60, and the engagement with the upper end. The space between the side wall and the ceiling plate member 60 is covered by the joint, and the first blind member 64 or the like is provided to extend along the side wall. Sometimes, when the first parting member 62 moves along the lower surface of the first blind member 64 toward the side wall W and the ceiling plate member 60 moves away from the side wall W, the claw portion 66 engages the hook portion 68. The first joining member 62 inclines and moves rearward. As a result, when the suspended ceiling shakes due to an earthquake, the ceiling base material and the ceiling plate material 60 are prevented from colliding with the side wall of the building, being damaged, and falling.

また、特許文献２の野縁構造は、対向する壁部にそれぞれ長尺状の下地材が水平方向に取り付けられ、対向して配された該下地材の室内側に長尺状の壁際野縁が取り付けられ、対向して配された該壁際野縁間に複数の野縁を架設し、これら野縁の端面等に防振パッキンを介在させたことから、下地材からの振動（水平方向）を野縁等の天井部に伝えないようにした天井構造を実現するというものである。 Further, in the joist structure of Patent Document 2, a long base material is attached to each of the opposing walls in the horizontal direction, and the long wall-side joist is attached to the indoor side of the base material arranged to face each other. is installed, and a plurality of joists are installed between the joists facing the wall, and anti-vibration packing is interposed on the end surfaces of these joists, so vibration from the base material (horizontal direction) It is to realize a ceiling structure that does not transmit to the ceiling such as the ceiling.

特許文献３に記載の天井構造は、吊りボルトによって支持された天井下地に天井板材が取り付けられた第１天井構造部と、上記天井板材よりも質量が軽くされた軽量天井板材を、上記吊りボルトよりも短い短吊りボルトに支持されている変形可能なワイヤーで吊るした第２天井構造部とを備えることで、地震時の揺れなどで天井が脱落するのを抑制でき、また異なる構造の第１天井構造部と第２天井構造部との天井高さを等しくすることができるというものである。 The ceiling structure described in Patent Document 3 includes a first ceiling structure part in which a ceiling plate material is attached to a ceiling base supported by suspension bolts, and a lightweight ceiling plate material having a lighter mass than the ceiling plate material, which are attached to the suspension bolts. By providing a second ceiling structure suspended by a deformable wire supported by a short suspension bolt shorter than the second ceiling structure, it is possible to suppress the ceiling from falling off due to shaking during an earthquake, etc., and the first ceiling structure having a different structure The ceiling height of the ceiling structure part and the ceiling height of the second ceiling structure part can be made equal.

以下、本発明の実施の形態を図面に基づいて説明する。
図１は、第一の実施の形態に係る天井の下地構造（一部）を示したものである。
天井の下地構造は、例えば、下地棒材（野縁受け材２、野縁材４）及び天井板材６等を、ハンガーなどで吊るした吊り天井が適用できる。この場合、天井基礎部から吊るしたハンガーに野縁受け材２を支持させ、また野縁材４は、野縁受け材２と交差（直交）する状態に配置し、クリップ３等を用いて野縁受け材２の下部に固定する。 BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows (a part of) the underlying structure of the ceiling according to the first embodiment.
For the underlying structure of the ceiling, for example, a suspended ceiling in which underlying rods (the ceiling joist receiving material 2, the ceiling joist material 4), the ceiling plate material 6, and the like are hung by hangers or the like can be applied. In this case, the joist receiving material 2 is supported by a hanger hung from the ceiling foundation, and the joist receiving material 4 is arranged in a state of intersecting (perpendicularly) with the joist receiving material 2, and the clip 3 or the like is used to It is fixed to the lower part of the edge receiving material 2.

さらに、この天井の下地構造では、下地棒材としての野縁材４を保持する保持部材８、及び天井板材６を受けこれを保持する受け部材１０等を用いる。これら保持部材８及び受け部材１０は、建物の壁部１２等に取り付けて使用され、また受け部材１０は保持部材８の下側に配置される。 Furthermore, in this base structure of the ceiling, a holding member 8 for holding the ceiling joist 4 as a base bar, and a receiving member 10 for receiving and holding the ceiling plate material 6 are used. The holding member 8 and the receiving member 10 are used by being attached to a wall portion 12 of a building, and the receiving member 10 is arranged below the holding member 8 .

図２（ａ）（ｂ）に示すように、上記保持部材８は、上板部１４、縦板部１６及び下板部１８からなり、開口部９が横向きに形成された断面コの字状の長尺材である。また、保持部材８の上板部１４の先端部付近には、斜め上方に屈曲したガイド片部２２が設けられている。さらに、保持部材８の上板部１４には、上板部１４の長尺方向に向け、短尺方向に長い長孔部２０が所定間隔をおいて複数形成されている。この長孔部２０には、ビス５２等の止着具が挿通される。
ここで、保持部材８の上板部１４の幅（Ｌ）は５５ｍｍ、ガイド片部２２の幅（Ｍ）は１０ｍｍとしている。保持部材８の縦板部１６の高さ幅（内部側）（Ｈ）は４０．５ｍｍ、下板部１８の幅（Ｎ）は６０ｍｍとしている。また、保持部材８の板厚は０．６ｍｍである。このように、保持部材８の上板部１４の幅は下板部１８の幅と同程度としている。 As shown in FIGS. 2(a) and 2(b), the holding member 8 comprises an upper plate portion 14, a vertical plate portion 16 and a lower plate portion 18, and has a U-shaped cross section with an opening 9 extending horizontally. It is a long piece of material. A guide piece portion 22 bent obliquely upward is provided near the tip portion of the upper plate portion 14 of the holding member 8 . Further, the upper plate portion 14 of the holding member 8 is formed with a plurality of long holes 20 elongated in the short direction at predetermined intervals in the longitudinal direction of the upper plate portion 14 . A fastener such as a screw 52 is inserted through the long hole portion 20 .
Here, the width (L) of the upper plate portion 14 of the holding member 8 is 55 mm, and the width (M) of the guide piece portion 22 is 10 mm. The height width (inner side) (H) of the vertical plate portion 16 of the holding member 8 is 40.5 mm, and the width (N) of the lower plate portion 18 is 60 mm. Further, the plate thickness of the holding member 8 is 0.6 mm. Thus, the width of the upper plate portion 14 of the holding member 8 is approximately the same as the width of the lower plate portion 18 .

上記保持部材８の上板部１４及び下板部１８の幅（Ｌ、Ｎ）は、地震時等の振動（揺れ）により、予測される天井部の野縁材４及び天井板材６の移動（水平方向）範囲等、を考慮して決定する。
なお、地震時等では建物の躯体（天井基礎部、壁部１２等）が揺れ、これに伴い天井の下地材（野縁受け材２、野縁材４、天井板材６等）が揺れる場合、また建物内部の機械振動、風圧等により天井下地の構造物が揺れる場合等がある。また、地震時等には横揺れが多いが、震源により縦揺れが加わる場合がある。これら何れの場合も、建物の躯体と天井の下地材等とが相対的に変位し、振動、移動することが考えられる。
保持部材８の開口部９に先端部５を突入させた野縁材４は、保持部材８の内部を移動するが、これは壁部１２の振動、移動による場合、野縁材４自体の移動、振動による場合があり、このため野縁材４と保持部材８間は変位し、野縁材４は保持部材８に対して相対的に移動する。 The width (L, N) of the upper plate portion 14 and the lower plate portion 18 of the holding member 8 is determined by the movement ( Horizontal direction) range, etc.
In the event of an earthquake, etc., if the building frame (ceiling foundation, wall 12, etc.) shakes and the ceiling base material (ceiling support material 2, ceiling material 4, ceiling plate material 6, etc.) shakes accordingly, In addition, the structure under the ceiling may shake due to mechanical vibration, wind pressure, etc. inside the building. In addition, although there are many horizontal swaying during an earthquake, vertical swaying may be added depending on the epicenter. In any of these cases, it is conceivable that the frame of the building and the base material of the ceiling or the like are relatively displaced, vibrated, and moved.
The hoisting material 4 with the tip portion 5 inserted into the opening 9 of the holding member 8 moves inside the holding member 8, but if this is due to the vibration and movement of the wall 12, the movement of the hoisting material 4 itself , it may be due to vibration, so that there is a displacement between the joist 4 and the retaining member 8 and the joist 4 moves relative to the retaining member 8 .

また、保持部材８の縦板部１６の高さ幅（Ｈ）は、この保持部材８の開口部９内を移動する野縁材４の縦幅に基づいて定める。この場合、保持部材８の上板部１４と野縁材４の上面部４６、また下板部１８と野縁材４の下面部５０との間に、保持部材８に対する野縁材４の相対移動を妨げないよう、隙間（遊び）をもたせておく。 Further, the height width (H) of the vertical plate portion 16 of the holding member 8 is determined based on the vertical width of the joist member 4 that moves through the opening 9 of the holding member 8 . In this case, between the upper plate portion 14 of the holding member 8 and the upper surface portion 46 of the hoisting member 4, and between the lower plate portion 18 and the lower surface portion 50 of the hoisting member 4, the relative position of the hoisting member 4 with respect to the holding member 8 is provided. Leave a gap (play) so as not to hinder movement.

これにより、地震時等の横揺れに対しては、保持部材８は野縁材４の横（水平）方向の移動（振動）を自由に行わせ、また縦揺れに対しては、上下方向の移動（振動）を抑制する。なお、縦揺れの場合、建物の躯体と天井の下地材との相対的な変位は比較的少ないため、上下振動は抑制するのがむしろ有効である。
また、上記隙間（遊び）を少し広く設け、野縁材４の上部又は／及び下部と保持部材８（上板部１４、下板部１８）との間に弾性材を介在させ、野縁材４の上下移動を弾性吸収し、また軋み音等を防止するようにしてもよい。 As a result, the holding member 8 can freely move (vibrate) the joist 4 in the lateral (horizontal) direction against horizontal shaking such as an earthquake, and against vertical shaking, it can move up and down. Suppress movement (vibration). In the case of pitching, since the relative displacement between the building frame and the base material of the ceiling is relatively small, it is rather effective to suppress the vertical vibration.
In addition, the gap (play) is provided a little wider, and an elastic material is interposed between the upper part or / and the lower part of the joist material 4 and the holding member 8 (upper plate part 14, lower plate part 18), and the joist material It is also possible to elastically absorb the vertical movement of 4 and prevent squeaking noise and the like.

上記受け部材１０は、図３（ａ）（ｂ）に示すように、上下向きの背面板部２６、この背面板部２６の下端部から横向きに形成される横板部２８、及び当該横板部２８の先端部を上向きに屈曲した板受け部３０からなる断面Ｌ字状の長尺材である。
上記板受け部３０は、上向きの立上板部３２、及びこの上部から壁部１２方向（反壁部１２方向の形状も可能）に向けて屈曲した受け片部３４を有している。 As shown in FIGS. 3(a) and 3(b), the receiving member 10 includes an up-down rear plate portion 26, a horizontal plate portion 28 formed laterally from the lower end of the rear plate portion 26, and the horizontal plate portion 28. It is a long member having an L-shaped cross section, which is composed of a plate support portion 30 in which the tip portion of the portion 28 is bent upward.
The plate receiving portion 30 has an upward rising plate portion 32 and a receiving piece portion 34 bent from the upper portion toward the wall portion 12 (a shape opposite to the wall portion 12 direction is also possible).

また、ここでは受け部材１０の背面板部２６の高さ幅（Ｐ）は１００ｍｍ、横板部２８の幅（Ｑ）は６０ｍｍ、立上板部３２の高さ幅（Ｒ）は７．５ｍｍ、及び受け片部３４の幅（Ｓ）は７ｍｍとしている。ここで、受け部材１０の横板部２８の幅（Ｑ）と、保持部材の下板部１８の幅（Ｎ）とは、同じ大きさ（６０ｍｍ）としており、野縁材４と天井板材６との移動の許容範囲を同じに合わせている。
上記保持部材８及び受け部材１０は、何れも軽量鋼板をプレス加工等により屈曲成形したものであり、また何れも鋼板の板厚は０．６ｍｍである。 Here, the height width (P) of the back plate portion 26 of the receiving member 10 is 100 mm, the width (Q) of the horizontal plate portion 28 is 60 mm, and the height width (R) of the rising plate portion 32 is 7.5 mm. , and the width (S) of the receiving piece 34 is 7 mm. Here, the width (Q) of the horizontal plate portion 28 of the receiving member 10 and the width (N) of the lower plate portion 18 of the holding member are the same size (60 mm). And have the same tolerance for movement.
Both the holding member 8 and the receiving member 10 are formed by bending a lightweight steel plate by press working or the like, and the plate thickness of each steel plate is 0.6 mm.

上記野縁受け材２は、鋼板を屈曲成形したものであり、上片部４０、縦片部４２及び下片部４４からなる断面コの字状の長尺材である。また、上記野縁材４は、軽量鋼板を屈曲成形したもので、上面部４６、左右の側面部４８，４８、及び下面部５０からなる断面ロの字状の長尺材である。
図１に示すように、野縁材４は、通常クリップ３等を用いて野縁受け材２の下部に固定され、クリップ３の断面Ｕ字状の野縁受け部５６で野縁材４を載置保持し、クリップ３の上部の係止部５７を野縁受け材２の上片部４０に係止させ、野縁材４を固定する。また、野縁受け材２等の天井の下地材は、天井基礎部から吊るしたハンガー等の吊り具によって支持する。 The ceiling joist receiving member 2 is formed by bending a steel plate. The joist member 4 is formed by bending a lightweight steel plate, and is an elongated member having a square cross section and comprising an upper surface portion 46 , left and right side portions 48 , 48 and a lower surface portion 50 .
As shown in FIG. 1, the joist material 4 is usually fixed to the lower part of the joist receiving material 2 using a clip 3 or the like, and the hoist material 4 is held by the joist receiving part 56 of the clip 3 having a U-shaped cross section. The hoisting member 4 is fixed by placing and holding the hoisting member 4 by causing the upper engaging portion 57 of the clip 3 to be engaged with the upper piece portion 40 of the ceiling joist receiving member 2 . In addition, the base material of the ceiling such as the joist receiving material 2 is supported by a hanging tool such as a hanger hung from the base of the ceiling.

さて、上記保持部材８及び受け部材１０は、天井際の壁部１２に配置固定する。具体的には、保持部材８及び受け部材１０は、天井部に配置される各野縁材４の長尺方向の先端部側に配置する。これら野縁材４は、平行且つ所定の間隔をおいて並設される。 Now, the holding member 8 and the receiving member 10 are arranged and fixed to the wall portion 12 near the ceiling. Specifically, the holding member 8 and the receiving member 10 are arranged on the front end side in the longitudinal direction of each joist member 4 arranged on the ceiling. These hoisting materials 4 are arranged in parallel at predetermined intervals.

ここで、上記保持部材８及び受け部材１０を配置する天井の下地構造について説明する。
上記保持部材８及び受け部材１０の配置形態については、矩形状の天井部の向い合う二辺の各部位に配置する形態、又は天井部の一辺の部位のみに配置する形態がある。なお、上記何れの配置形態についても、各辺の部位に配置する基本的な下地構造は同じである。 Here, the underlying structure of the ceiling on which the holding member 8 and the receiving member 10 are arranged will be described.
The holding member 8 and the receiving member 10 may be arranged on two opposite sides of the rectangular ceiling, or may be arranged only on one side of the ceiling. It should be noted that the basic base structure to be arranged on each side is the same for any of the arrangement forms described above.

保持部材８は、天井際の壁部１２に、横向きに且つその開口部９を内側に向けて配置する。これと同時に、保持部材８の下側に受け部材１０の横板部２８が位置するよう、受け部材１０を配置する。このとき、受け部材１０の背面板部２６を、保持部材８の縦板部１６と壁部１２との間に配置し、背面板部２６と縦板部１６とを重ねる。そして、ビス３８を用い、縦板部１６から背面板部２６を貫通させ、これらを壁部１２に螺設し固定する。 The holding member 8 is arranged on the wall 12 near the ceiling, facing sideways and with its opening 9 facing inward. At the same time, the receiving member 10 is arranged so that the lateral plate portion 28 of the receiving member 10 is positioned below the holding member 8 . At this time, the rear plate portion 26 of the receiving member 10 is arranged between the vertical plate portion 16 of the holding member 8 and the wall portion 12, and the rear plate portion 26 and the vertical plate portion 16 are overlapped. Then, screws 38 are used to pass through the rear plate portion 26 from the vertical plate portion 16 , and these are screwed and fixed to the wall portion 12 .

上記壁部１２の内部には、所定間隔でスタッド材１５が骨組み材として一定間隔をおいて配置されている。これら上下向きのスタッド材１５の上部に、保持部材８をビス３８により螺設する。上記保持部材８のビス３８による固定は、天井際の一辺部位の全体（端から端）にわたって行い、例えばスタッド材１５毎に行う。天井際の一辺部位に配置されるスタッド材１５は、複数本、例えば３本以上配置する。
通常、断面コの字状のスタッド材１５の上部側及び下部側にはランナー材（断面コの字状）が配置され、これらランナー材の溝部にスタッド材の上端部及び下端部を嵌めて固定する。なお、保持部材８は上記ランナー材に取り付けることも可能である。 Inside the wall portion 12, stud members 15 are arranged at predetermined intervals as frame members. A holding member 8 is screwed with a screw 38 to the upper portion of these stud members 15 directed vertically. The fixing of the holding member 8 with the screws 38 is performed over the entire side portion (end to end) near the ceiling, for example, for each stud member 15 . A plurality of, for example, three or more, stud members 15 are arranged on one side near the ceiling.
Normally, runner members (having a U-shaped cross section) are arranged on the upper and lower sides of the stud member 15 having a U-shaped cross section, and the upper and lower ends of the stud member are fitted into the grooves of these runner members and fixed. do. The holding member 8 can also be attached to the runner material.

次に、吊るされたハンガーに野縁受け材２を支持させ、所定間隔をおいて平行に配置された野縁受け材２の下部に、クリップ３を用いて野縁材４を取り付ける。野縁材４は、野縁受け材２の下部に野縁受け材２とは交差（直交）する方向に配置し、互いに所定の間隔を置き、各野縁材４同士を平行に並べて取り付ける。
そして、各野縁材４の長尺方向の先端部５と、天井際の壁部１２との間は、地震時等により野縁材４或いは壁部１２等が水平方向に揺れ移動（相対移動）することが予測される。 Next, the ceiling joist receiving members 2 are supported by the hanging hangers, and the joist members 4 are attached using the clips 3 to the lower portions of the ceiling joist receiving members 2 arranged in parallel at predetermined intervals. The joist materials 4 are arranged in a direction intersecting (perpendicularly) with the joist receiving members 2 under the joist receiving members 2, and the joist members 4 are arranged in parallel with each other at predetermined intervals.
And between the tip part 5 of each joist 4 and the wall part 12 near the ceiling, the joist 4 or the wall part 12 or the like shakes in the horizontal direction (relative movement) due to an earthquake or the like. ).

このため、予測される範囲の移動（相対移動）を確保吸収し得るよう、野縁材４の先端部５と保持部材８の縦板部１６との間に空間部１１を設ける。この空間部１１は、野縁材４の先端部５と壁部１２との間の空間部に略相当する。また、野縁材４の長尺方向の両側の壁部１２につき、これら両壁部１２同士の間隔が変位することが予測される場合がある。
このように、上記移動（相対移動）が発生した場合、野縁材４の先端部５が保持部材８の内部を自由に移動できることが望ましい。このため、空間部１１の空間幅（Ｗ）の寸法、および保持部材８の上板部１４及び下板部１８の幅を、適切な大きさに設定する。 For this reason, a space portion 11 is provided between the tip portion 5 of the joist member 4 and the vertical plate portion 16 of the holding member 8 so as to secure and absorb the movement (relative movement) in the expected range. This space portion 11 substantially corresponds to the space portion between the tip portion 5 of the ceiling joist 4 and the wall portion 12 . In addition, it may be predicted that the interval between the walls 12 on both sides of the ceiling joist 4 in the longitudinal direction will be displaced.
In this way, it is desirable that the tip portion 5 of the hoisting member 4 can move freely inside the holding member 8 when the movement (relative movement) occurs. Therefore, the dimension of the space width (W) of the space portion 11 and the widths of the upper plate portion 14 and the lower plate portion 18 of the holding member 8 are set to appropriate sizes.

そして、部屋の壁部１２に向けて配置される野縁材４の先端部５を、保持部材８の開口部９から内部に差し込む。このとき、野縁材４の先端部５が保持部材８のガイド片部２２に案内され、野縁材４の差し込みが容易且つ迅速に行える。 Then, the tip portion 5 of the joist member 4 arranged toward the wall portion 12 of the room is inserted inside from the opening portion 9 of the holding member 8. - 特許庁At this time, the tip portion 5 of the ceiling joist 4 is guided by the guide piece portion 22 of the holding member 8, and the insertion of the ceiling joist 4 can be easily and quickly performed.

ここでは、壁部１２と向き合う野縁材４の長尺方向の先端部５と、保持部材８の縦板部２６との間の空間部１１の空間幅（Ｗ）を３０ｍｍとしている。この場合、保持部材８の下板部１８の幅（Ｎ）は６０ｍｍであるから、この奥行きの半分程度、野縁材４の先端部５が突入した状態である。このため、野縁材４は上記保持部材８に半分突入した位置を基準に、左右に±３０ｍｍの移動（振動）が可能となる。
また、野縁材４の下部に取り付けられる天井板材６は、その端部７を野縁材４の先端部５と同じ（同一垂直面）に揃えて配置し、天井板材６の端部７と壁部１２との間も、上記空間幅（Ｗ）と同程度の幅の空間部（隙間部１３）を確保する。 Here, the space width (W) of the space portion 11 between the longitudinal end portion 5 of the ceiling joist 4 facing the wall portion 12 and the vertical plate portion 26 of the holding member 8 is 30 mm. In this case, since the width (N) of the lower plate portion 18 of the holding member 8 is 60 mm, the front end portion 5 of the hoisting member 4 protrudes about half of this depth. For this reason, the hoisting member 4 can move (vibrate) to the left and right by ±30 mm with reference to the position where it is half thrust into the holding member 8 .
In addition, the ceiling board material 6 attached to the lower part of the ceiling board material 4 is arranged so that the end part 7 is aligned with the tip part 5 of the ceiling board material 4 (same vertical plane), and the end part 7 of the ceiling board material 6 A space (clearance 13) having a width approximately equal to the space width (W) is secured between the wall 12 and the wall 12 as well.

そして、野縁材４の長尺方向の先端部５を、上記保持部材８の開口部９内に差し込む。このとき、野縁材４の先端部５と保持部材８の縦板部１６との間（これは野縁材４の先端部５と壁部１２との間の距離と略同じ）には、振動等により野縁材４が移動可能な余地として上記空間部１１を設けておく。 Then, the tip portion 5 of the hoisting member 4 in the longitudinal direction is inserted into the opening portion 9 of the holding member 8 . At this time, between the tip portion 5 of the joist material 4 and the vertical plate portion 16 of the holding member 8 (this is approximately the same as the distance between the tip portion 5 of the joist material 4 and the wall portion 12), The space part 11 is provided as a room for the framing material 4 to move due to vibration or the like.

上記保持部材８に差し込まれた野縁材４は、野縁材４の長尺方向の移動が可能であるが、野縁材４が壁部１２に沿う方向に移動することも可能であり、このため交差する二方向の揺れに対して振動を吸収することができる。
また、天井の下地材として、野縁材４等の揺れが必要以上にならないよう所定範囲に制限し、天井の下地材を保護することも考えられる。このため、ここでは保持部材８の上板部１４に、壁部１２に向けて長い長孔部２０を設け、この長孔部２０の長孔の範囲内に野縁材４の移動（相対）を制限することとした。 The joist material 4 inserted into the holding member 8 can move in the longitudinal direction of the joist material 4, but it is also possible for the joist material 4 to move in the direction along the wall part 12, For this reason, it is possible to absorb vibrations in two intersecting directions.
It is also conceivable to protect the ceiling base material by restricting the swinging of the joist 4 or the like as the base material of the ceiling to a predetermined range so that it does not become unnecessarily swinging. For this reason, here, the upper plate portion 14 of the holding member 8 is provided with a long hole portion 20 toward the wall portion 12, and the hoisting member 4 moves (relatively) within the range of the long hole of the long hole portion 20. was to be restricted.

上記上板部１４の長尺方向に所定間隔をおいて設けられた長孔部２０は、野縁材４の上面部４６の幅寸法よりも狭い間隔で設けられており、野縁材４の上面部４６には、常に何れかの長孔部２０が位置するようにしている。この長孔部２０は、上板部１４の短尺方向の端部近傍から中央部にかけて長い孔状に形成されている。 The long hole portions 20 provided at predetermined intervals in the longitudinal direction of the upper plate portion 14 are provided at intervals narrower than the width dimension of the upper surface portion 46 of the joist material 4. One of the elongated holes 20 is always positioned on the upper surface portion 46 . The long hole portion 20 is formed in a long hole shape from the vicinity of the end portion in the short direction of the upper plate portion 14 to the central portion thereof.

そして、図４に示すように、保持部材８の長孔部２０の内、野縁材４の上面部４６が下部に配置される箇所の長孔部２０から、ビス５２等の止着具を螺入する。また、ビス５２と長孔部２０（短尺側）との間、及びビス５２の頭部５３と保持部材８の上板部１４との間にそれぞれ隙間を設け、保持部材８に対する野縁材４の相対移動の自由を妨げないようにする。このように、ビス５１等の止着具はその一部（頭部等）を上板部１４から突出させておく。なお、ビス５２の他、長孔部２０から挿通可能で野縁材４に固定できる棒状片の止着具であれば使用可能である。 Then, as shown in FIG. 4, fasteners such as screws 52 are inserted from the elongated holes 20 of the holding member 8 where the upper surface portion 46 of the joist member 4 is arranged below. screw in. Also, gaps are provided between the screw 52 and the long hole portion 20 (short side) and between the head portion 53 of the screw 52 and the upper plate portion 14 of the holding member 8, and the joist member 4 for the holding member 8 is provided. do not impede the freedom of relative movement of In this manner, a part (head portion, etc.) of the fastener such as the screw 51 is allowed to protrude from the upper plate portion 14 . In addition to the screws 52, any rod-like fastener that can be inserted through the elongated hole 20 and fixed to the hoisting member 4 can be used.

他の野縁材４についても、同様に、保持部材８の長孔部２０から野縁材４の上部として上面部４６にビス５２を螺入し取り付ける。上記保持部材８の長孔部２０からのビス５２の取付けは、天井部の向い合う二辺の部位の内、野縁材４の一方側の端部が向かう部位のみ、或いは野縁材４の一方側及び他方側の両端部が向かう部位について行う。
地震時等の揺れにより、保持部材８に対して野縁材４が相対移動した場合、当該野縁材４の移動に伴い上記ビス５２が長孔部２０内を移動する。 Similarly, the other hoisting materials 4 are attached by screwing screws 52 from the elongated holes 20 of the holding members 8 into the upper surfaces 46 of the hoisting materials 4 as the upper portions of the hoisting materials 4 . The screw 52 is attached from the long hole 20 of the holding member 8 only to the part where one end of the ceiling joist 4 faces among the two opposing sides of the ceiling, or This is done for the portions where both ends of one side and the other side face.
When the hoisting member 4 moves relative to the holding member 8 due to shaking during an earthquake or the like, the screw 52 moves inside the long hole portion 20 along with the movement of the hoisting member 4 .

これにより野縁材４の移動、つまりこれと連動するビス５２の移動は長孔部２０の長孔の範囲に制限され、ビス５２は野縁材４の移動の範囲を制限するストッパーの役割を果たす。なお、上記長孔部２０及びビス５２を用いた野縁材４の移動の制限手段は、予測される野縁材４等の揺れの大きさ、或いは保持部材８からの野縁材４の外れ防止等、必要に応じて採用する。
なお、野縁材４の揺れが、野縁材４の長尺方向のみならずこれと交差（直交）する方向にも発生し、この揺れを許容し吸収する必要がある場合には、上記長孔部２０による制限機能は用いないでフリーな状態とすることもできる。 As a result, the movement of the ceiling joist 4, that is, the movement of the screw 52 linked thereto is limited to the range of the long hole 20, and the screw 52 serves as a stopper that limits the range of movement of the ceiling joist 4. Fulfill. It should be noted that means for restricting the movement of the ceiling joist 4 using the long hole 20 and the screw 52 is the magnitude of the predicted shaking of the ceiling joist 4 or the like, or the detachment of the ceiling joist 4 from the holding member 8. Adopted as necessary for prevention, etc.
In addition, the swaying of the joist material 4 occurs not only in the longitudinal direction of the joist material 4 but also in the direction that intersects (perpendicularly) with it, and if it is necessary to allow and absorb this sway, the above-mentioned length A free state can also be achieved without using the restriction function of the hole 20 .

上記野縁材４の下部には、天井板材６を取り付ける。ここでは、天井板材６の下面からビス５４を捩じ込み、さらにこのビス５４を野縁材４の下面部５０に螺設し、天井板材６を野縁材４の下部に固定する。 A ceiling plate material 6 is attached to the lower part of the hoisting material 4. - 特許庁Here, a screw 54 is screwed in from the lower surface of the ceiling plate material 6, and the screw 54 is further screwed into the lower surface portion 50 of the ceiling joist material 4 to fix the ceiling plate material 6 to the lower part of the ceiling joist material 4.

また、野縁材４の先端部５と天井板材６の壁部１２に面する端部７とは、これらを揃えて（同一垂直面）配置する。天井板材６は野縁材４に固定されているため、野縁材４と天井板材６とは一体的に振動し移動する。このため、野縁材４の先端部５と天井板材６の端部７とを上記揃えることで、両材料が保持部材８及び受け部材１０と関わる移動範囲を有効にかつ広く確保できる。 Also, the tip 5 of the ceiling joist 4 and the end 7 of the ceiling board 6 facing the wall 12 are aligned (in the same vertical plane). Since the ceiling board material 6 is fixed to the ceiling board material 4, the ceiling board material 4 and the ceiling board material 6 vibrate and move integrally. Therefore, by aligning the tip portion 5 of the ceiling joist member 4 and the end portion 7 of the ceiling plate member 6 as described above, it is possible to effectively secure a wide range of movement in which both materials are involved with the holding member 8 and the receiving member 10 .

保持部材８の下板部１８は、野縁材４と天井板材６との間の隙間（Ｇ）に挟まれ、差し込まれる状態で取り付ける。このため、上記天井板材６をビス５４で固定する際、保持部材８に近い位置のビス５４については、少し緩めに天井板材６と野縁材４との間を締結する。
これにより、野縁材４の下面部５０と天井板材６の上面部７との間に、保持部材８の下板部１８が差し込める程度の隙間（Ｇ）を形成する。この隙間（Ｇ）により、野縁材４と天井板材６とが一体的に揺れた場合、野縁材４と天井板材６との間に保持部材８の下板部１８を挟んだ状態で、この下板部１８の上下面を両材料が摺動しながら移動する。 The lower plate portion 18 of the holding member 8 is sandwiched in the gap (G) between the joist material 4 and the ceiling plate material 6 and attached in a state of being inserted. Therefore, when fixing the ceiling plate material 6 with the screws 54, the screws 54 located near the holding member 8 are slightly loosely tightened between the ceiling plate material 6 and the ceiling joist 4. As shown in FIG.
As a result, a gap (G) is formed between the lower surface portion 50 of the joist material 4 and the upper surface portion 7 of the ceiling plate material 6 so that the lower plate portion 18 of the holding member 8 can be inserted. Due to this gap (G), when the joist material 4 and the ceiling board material 6 are shaken integrally, with the lower plate part 18 of the holding member 8 sandwiched between the joist material 4 and the ceiling board material 6, Both materials move while sliding on the upper and lower surfaces of the lower plate portion 18 .

一方、上記天井板材６の取り付けの際には、天井板材６の壁部１２に面する端部７近傍を、受け部材１０の板受け部３０に載せる状態で配置する。
これにより、天井板材６の端部７近傍が受け部材１０の板受け部３０で支持され、また天井板材６の端部７近傍、及び天井板材６の端部７と壁部１２との間の隙間部１３の下側を受け部材１０の横板部２８が被い、目隠しの効果が得られ天井の際部の美観が図れる。 On the other hand, when the ceiling plate member 6 is attached, the vicinity of the end portion 7 of the ceiling plate member 6 facing the wall portion 12 is placed on the plate receiving portion 30 of the receiving member 10 .
As a result, the vicinity of the end portion 7 of the ceiling plate member 6 is supported by the plate receiving portion 30 of the receiving member 10, and the vicinity of the end portion 7 of the ceiling plate member 6 and the space between the end portion 7 of the ceiling plate member 6 and the wall portion 12 are supported. The lateral plate part 28 of the receiving member 10 covers the lower side of the gap part 13, and the effect of blinding is obtained, and the edge part of the ceiling can be made beautiful.

上記保持部材８は、主に野縁材４（及び天井板材６）を保持し、その移動（所定範囲内）を許容し、また受け部材１０は、天井板材６の移動を許容し、天井板材６の端部７近傍の下部を被う。このように、保持部材８及び受け部材１０等により、野縁材４及び天井板材６の自由な移動（振動）を許容し、地震等の揺れに対して免震保護し、また天井の際部の美観も図れる天井の下地構造が形成される。 The holding member 8 mainly holds the ceiling joist material 4 (and the ceiling board material 6) and allows its movement (within a predetermined range), and the receiving member 10 allows movement of the ceiling board material 6, It covers the lower part near the end 7 of 6. In this way, the holding member 8 and the receiving member 10 allow the free movement (vibration) of the ceiling framing material 4 and the ceiling board material 6, provide seismic isolation protection against vibrations such as earthquakes, and The base structure of the ceiling that can also achieve the aesthetic appearance of the ceiling is formed.

天井部の向い合う二辺の各部位に、上記下地構造を配置する形態を採用することも可能である。この場合、上記天井部の一辺の部位に配置する形態と同様な形態の下地構造を、天井部の他の辺の部位に配置する。そして、この他の辺に係る下地構造についても、壁部１２と向き合う野縁材４の長尺方向の先端部５と、保持部材８の縦板部２６との間の空間部１１の空間幅（Ｗ）を例えば３０ｍｍとする。
この場合、野縁材４（及び天井板材６）は、その先端部５を保持部材８の開口部９から内部へ差し込んだ状態（下板部１８の幅（Ｎ）の半分）を基準に、野縁材４の長尺方向に±３０ｍｍの移動（振動）が可能となる。 It is also possible to employ a mode in which the base structure is arranged at each of two opposing sides of the ceiling. In this case, the base structure having the same form as that arranged on one side of the ceiling is arranged on the other side of the ceiling. And also for the foundation structure related to the other sides, the space width of the space 11 between the longitudinal end portion 5 of the joist member 4 facing the wall portion 12 and the vertical plate portion 26 of the holding member 8 (W) is assumed to be 30 mm, for example.
In this case, the joist material 4 (and the ceiling plate material 6) is inserted into the opening 9 of the holding member 8 from the tip 5 (half the width (N) of the lower plate part 18). The movement (vibration) of ±30 mm in the longitudinal direction of the ceiling framing material 4 becomes possible.

また、上記天井部の一辺部位のみに上記天井の下地構造を配置する形態を採用することも可能である。この場合、他方の辺の部位については、例えば野縁材4及び天井板材６は、ともに壁部１２に当接した状態で配置する。このとき、野縁材４等は当接した壁部１２方向へは移動できないが、これと向い合う他方の辺の部位の下地構造により、反壁部１２方向の所定範囲については、振動による野縁材４の移動は自在に行える。
また、上記壁部１２に当接させた野縁材４等を壁部１２に固定することも可能であり、この場合、野縁材４は壁部１２とともに移動し、他方の辺の部位については上記と同様、上記下地構造により野縁材４の自由な移動が可能である。
この天井の下地構造を採用した場合においても、保持部材８及び受け部材１０を設けた側において、野縁材４の左右の移動が自由に行え、このため野縁材４の揺れを吸収することは可能であり、免震及び緩衝効果が発揮され天井の下地材等の保護が可能である。 It is also possible to employ a form in which the base structure of the ceiling is arranged only on one side of the ceiling. In this case, for the part on the other side, for example, the joist material 4 and the ceiling board material 6 are arranged in a state in which both are in contact with the wall portion 12 . At this time, the joist 4 and the like cannot move in the direction of the wall portion 12 in contact with it, but due to the base structure of the portion of the other side facing this, a predetermined range in the direction opposite to the wall portion 12 is affected by vibration. The edge member 4 can be freely moved.
In addition, it is possible to fix the joist material 4 or the like that is in contact with the wall part 12 to the wall part 12. In this case, the joist material 4 moves together with the wall part 12, As in the above, the base structure allows the hoisting material 4 to move freely.
Even when this base structure of the ceiling is adopted, the hoisting material 4 can be freely moved left and right on the side where the holding member 8 and the receiving member 10 are provided, so that the shaking of the hoisting material 4 can be absorbed. It is possible to protect the base material of the ceiling, etc. by demonstrating the seismic isolation and cushioning effect.

図５は、天井板材６を二枚重ねて使用した場合の例である。ここでは、野縁材４の下部に天井板材６を二枚重ねて配置し、下側の天井板材６の下面からビス５４を捩じ込み、さらにこのビス５４を野縁材４の下面部５０に螺設し、二枚の天井板材６を野縁材４の下部に固定する。
この場合、天井板材６の下面の位置が天井板材６の一枚分下がる。このため、これに応じて受け部材１０の取付け位置を下げ、受け部材１０の板受け部３０により下側の天井板材６の下面を保持できる位置に設定する。このように、天井板材６の下面の上下位置が変わる場合は、これに応じて受け部材１０の上下位置を調整する。その他の構成、作用等は、天井板材６が一枚の場合と同様である。 FIG. 5 shows an example in which two ceiling plate materials 6 are stacked and used. Here, two ceiling plate materials 6 are arranged under the ceiling joist 4, screws 54 are screwed from the lower surface of the lower ceiling plate 6, and the screws 54 are further screwed into the lower surface portion 50 of the ceiling joist 4. and two ceiling plate materials 6 are fixed to the lower part of the joist material 4.
In this case, the position of the lower surface of the ceiling plate material 6 is lowered by one sheet. Accordingly, the mounting position of the receiving member 10 is lowered so that the lower surface of the lower ceiling plate 6 can be held by the plate receiving portion 30 of the receiving member 10 . When the vertical position of the lower surface of the ceiling plate member 6 changes in this way, the vertical position of the receiving member 10 is adjusted accordingly. Other configurations, actions, etc. are the same as in the case where the ceiling plate member 6 is one sheet.

さて、地震時等には、建物の躯体（壁部１２等）及び天井部の下地材（野縁受け材２、野縁材４、天井板材６等）は激しく揺れ、また野縁材４及び天井板材６等は保持部材８及び受け部材１０に対して相対移動（振動）する。通常、壁部１２等と天井部の野縁材４等との間の相対移動により、両者間に歪み、衝突等が発生することが予測される。 Now, at the time of an earthquake, etc., the frame of the building (wall part 12, etc.) and the base material of the ceiling part (receiving material 2, joist material 4, ceiling board material 6, etc.) shake violently, and the joist material 4 and The ceiling plate 6 and the like move (vibrate) relative to the holding member 8 and the receiving member 10 . Normally, it is expected that relative movement between the walls 12 and the like and the ceiling joists 4 and the like will cause distortions, collisions, and the like between them.

この場合、上記天井の下地構造によれば、野縁材４が保持部材８の開口部９内を自由に移動し、併せて天井板材６の端部近傍が板受け部３０に保持された状態で、野縁材４と一体に移動する。このため、地震時等の揺れに対して、野縁材４の先端部５が保持部材８内を自在に移動して緩衝効果が発揮され、壁部１２等と天井下地材としての野縁材４等との間の歪み、衝突等が軽減され緩和される。 In this case, according to the base structure of the ceiling, the hoisting material 4 moves freely in the opening 9 of the holding member 8, and the vicinity of the end of the ceiling board 6 is held by the board receiving part 30. , and moves integrally with the joist material 4. For this reason, the tip part 5 of the ceiling framing material 4 moves freely in the holding member 8 to exert a buffering effect against shaking during an earthquake, etc., and the wall part 12 etc. and the ceiling base material Distortion, collision, etc. between 4 and so on are reduced and relaxed.

このように、上記天井の下地構造では、壁部１２等と野縁材４及び天井板材６等との間の振動（相対的変位）を吸収緩和する免震効果が発揮され、天井の下地材等が有効に保護される。特に、天井下地材（野縁受け材２、野縁材４、天井板材６等）をハンガー等で吊るした吊り天井の場合、上記相対的な変位が大きくなることが予測され、上記天井の下地構造が有効に適用できる。 In this way, in the base structure of the ceiling, the seismic isolation effect of absorbing and mitigating the vibration (relative displacement) between the walls 12 and the like and the ceiling joists 4 and the ceiling board 6 is exhibited. etc. are effectively protected. In particular, in the case of a suspended ceiling in which ceiling base materials (ceiling support material 2, joist material 4, ceiling board material 6, etc.) are hung with hangers or the like, it is expected that the above relative displacement will be large, and the ceiling base material Structure can be effectively applied.

従って、地震時等による揺れを上記天井の下地構造の機構が吸収し、壁部１２に追従して野縁材４等が強制的に移動振動することが軽減され、天井の下地構造に係る下地材（野縁材４、天井板材６等）の破損或いは落下等が防止できる。また、保持部材８の上板部１４及び下板部１８により、野縁材４の上下振動（揺れ）が抑制され、天井の下地構造に係る材料の破損或いは落下等が防止でき、また受け部材１０についても同様な効果が期待できる。 Therefore, the mechanism of the base structure of the ceiling absorbs the shaking caused by an earthquake or the like, and the forced movement and vibration of the ceiling framing material 4 etc. following the wall part 12 is reduced, and the base structure related to the base structure of the ceiling is reduced. It is possible to prevent damage or falling of materials (roofing material 4, ceiling board material 6, etc.). In addition, the upper plate portion 14 and the lower plate portion 18 of the holding member 8 suppress the vertical vibration (swaying) of the ceiling joist 4, preventing damage or falling of materials related to the base structure of the ceiling. A similar effect can be expected for 10 as well.

よって、第一の実施の形態に係る天井の下地構造によれば、地震時等による揺れに対して、天井の下地材等を揺れから保護して免震、耐震効果が発揮され、下地材等の破損、落下等の防止に寄与し、また天井部の美観も維持され、加えて構成が簡単であり施工性にも優れるという効果がある。 Therefore, according to the base structure of the ceiling according to the first embodiment, the base material etc. of the ceiling are protected from shaking due to an earthquake or the like, and the effect of seismic isolation and earthquake resistance is exhibited.
