Description

本発明は、天井構造に関する。   The present invention relates to a ceiling structure.

従来の天井構造としては、天井板を支持する天井下地を吊ボルトで吊り下げたものが知られている（例えば特許文献１参照）。吊ボルトは、上階床スラブなどの支持構造物から垂設されており、その下端部に天井下地を構成する複数の天井下地構成材が接続されている。天井下地構成材は、直線状または格子状に組み付けられている。天井下地構成材を格子状が組み付けられている場合は、平行配置された複数の野縁受けの下側に複数の野縁を取り付ける。この野縁は、野縁受けに対して直角方向に延在している。   As a conventional ceiling structure, one in which a ceiling base that supports a ceiling board is suspended by a suspension bolt is known (see, for example, Patent Document 1). The suspension bolt is suspended from a support structure such as an upper floor slab, and a plurality of ceiling foundation components constituting the ceiling foundation are connected to the lower end of the suspension bolt. The ceiling base component is assembled in a straight line shape or a lattice shape. When the lattice structure is assembled to the ceiling base component, a plurality of field edges are attached to the lower side of the plurality of field edge receivers arranged in parallel. This field edge extends in a direction perpendicular to the field edge receiver.

特開２０１０−２５５３０８号公報JP 2010-255308 A

従来の天井構造では、図５に示すように、天井の周縁部（天井周りの壁面１１０に近接する部分）において、天井下地構成材１００の小口面１０５が壁面１１０に対向するようになっている。ここで、天井下地構成材１００は、長さ寸法の誤差や施工時の取付位置の誤差によって、小口面１０５が壁面１１０に当接している天井下地構成材１００と、小口面１０５が壁面１１０から離間している天井下地構成材１００が混在していた。   In the conventional ceiling structure, as shown in FIG. 5, the edge surface 105 of the ceiling foundation component 100 is opposed to the wall surface 110 at the peripheral edge of the ceiling (portion close to the wall surface 110 around the ceiling). . Here, the ceiling foundation component 100 includes a ceiling foundation component 100 in which the small edge surface 105 abuts against the wall surface 110 due to an error in length and an attachment position at the time of construction, and the small edge surface 105 extends from the wall surface 110. The ceiling base component 100 which is spaced apart is mixed.

このような場合において、地震等により天井に揺れが生じると、壁面１１０に天井下地構成材１００が当接している部分に応力が集中する。すると、壁面１１０に当接している天井下地構成材１００に座屈が生じたり、壁面１１０の天井下地構成材１００が当接している部分に局所的な損傷が発生してしまうおそれがあった。   In such a case, when the ceiling shakes due to an earthquake or the like, stress concentrates on a portion where the ceiling base component 100 is in contact with the wall surface 110. Then, there is a possibility that buckling occurs in the ceiling foundation component 100 in contact with the wall surface 110 or local damage occurs in a portion of the wall surface 110 in contact with the ceiling foundation component 100.

以上のような観点から、本発明は、天井下地構成材または壁面に局所的な応力が集中するのを防止できる天井構造を提供することを課題とする。   In view of the above, it is an object of the present invention to provide a ceiling structure capable of preventing local stress from concentrating on a ceiling base material or a wall surface.

前記課題を解決するための請求項１に係る発明は、天井部に設けられた吊材と、前記吊材に支持された天井下地と、前記天井下地に支持された天井板と、壁面に沿って配置された通し材とを備えた天井構造であって、前記天井下地は、壁面と交差する方向に沿って延在する複数の天井下地構成材を有し、前記通し材は、複数の前記天井下地構成材の端部同士を連結するとともに、前記天井下地構成材の端部よりも前記壁面側に張り出していることを特徴とする天井構造である。   The invention according to claim 1 for solving the above-described problem is in accordance with a suspension member provided on a ceiling portion, a ceiling foundation supported by the suspension member, a ceiling plate supported by the ceiling foundation, and a wall surface. A ceiling structure provided with a through material, wherein the ceiling base has a plurality of ceiling base components extending along a direction intersecting the wall surface, and the through material includes a plurality of the base materials The ceiling structure is characterized in that the end portions of the ceiling foundation constituent material are connected to each other, and projects from the end portion of the ceiling foundation constituent material to the wall surface side.

このような構成によれば、地震などにより天井に揺れが生じた場合でも、通し材が壁面に接触するので、天井下地構成材が壁面に接触するのを防止できる。通し材は壁面に沿って配置されているので、天井の揺動時に壁面に作用する応力を分散でき、天井下地構成材および壁面に局所的な応力が集中するのを防止できる。その結果、壁面に局所的な損傷が発生し難くなる。   According to such a configuration, even when the ceiling is shaken due to an earthquake or the like, the threading material comes into contact with the wall surface, so that the ceiling base component can be prevented from coming into contact with the wall surface. Since the threading material is disposed along the wall surface, the stress acting on the wall surface when the ceiling is swung can be dispersed, and local stress can be prevented from concentrating on the ceiling base material and the wall surface. As a result, local damage is less likely to occur on the wall surface.

請求項２に係る発明は、前記通し材が、前記天井下地構成材の上面または下面に当接する接合板部と、前記天井下地構成材の端面に対向する対向板部とを備えており、前記対向板部は、前記壁面と平行に配置されていることを特徴とする。このような構成によれば、天井の揺動時に、通し材の対向板部が壁面に面接触するので、天井下地材から壁面に作用する応力をより一層分散することができる。   According to a second aspect of the present invention, the threading member includes a joining plate portion that abuts on an upper surface or a lower surface of the ceiling foundation component, and a counter plate portion that faces an end surface of the ceiling foundation component, The counter plate portion is arranged in parallel with the wall surface. According to such a configuration, since the opposing plate portion of the threading material is in surface contact with the wall surface when the ceiling is swung, the stress acting on the wall surface from the ceiling base material can be further dispersed.

本発明に係る天井構造によれば、天井が壁面に衝突する際に、壁面に作用する応力を分散できるので、天井下地構成材または壁面に局所的な応力が集中するのを防止でき、その結果、壁面に局所的な損傷が発生し難くなる。   According to the ceiling structure according to the present invention, when the ceiling collides with the wall surface, the stress acting on the wall surface can be dispersed, so that local stress can be prevented from concentrating on the ceiling base material or the wall surface. It is difficult for local damage to the wall surface.

天井板２０は、野縁１２の下面にビス止めされている。複数の天井板２０で天井面が形成されており、天井面の周縁部（壁面５に隣接する天井面全体の周縁部）には、回り縁２１が設けられている。   The ceiling board 20 is screwed to the lower surface of the field edge 12. A ceiling surface is formed by the plurality of ceiling plates 20, and a peripheral edge 21 is provided at a peripheral portion of the ceiling surface (peripheral portion of the entire ceiling surface adjacent to the wall surface 5).

通し材３０は、野縁受け１１の端部同士または野縁１２の端部同士を連結する部材である。通し材３０は、野縁受け１１の端部または野縁１２の端部よりも壁面５側に張り出している。通し材３０は、接合板部３１と対向板部３２とを備えている。接合板部３１は、野縁受け１１の上面または野縁１２の下面に当接する。対向板部３２は、野縁受け１１または野縁１２の端面（小口面）に対向する。通し材３０は、断面Ｌ字形状を呈する例えばスチール製のアングル材にて構成されている。通し材３０は、壁面５に沿って（本実施形態では壁面５に平行に）配置されている。通し材３０は、断面Ｌ字の一方の面が接合板部３１となり、他方の面が対向板部３２となる。   The threading member 30 is a member that connects the ends of the field edge receivers 11 or the edge parts of the field edge 12. The threading member 30 projects from the end of the field edge receiver 11 or the edge of the field edge 12 toward the wall surface 5. The threading member 30 includes a joining plate portion 31 and a counter plate portion 32. The joining plate portion 31 contacts the upper surface of the field edge receiver 11 or the lower surface of the field edge 12. The facing plate portion 32 faces the end surface (small edge surface) of the field edge receiver 11 or the field edge 12. The threading member 30 is made of, for example, a steel angle member having an L-shaped cross section. The threading material 30 is arranged along the wall surface 5 (in this embodiment, parallel to the wall surface 5). In the threading material 30, one surface having an L-shaped cross section serves as a joining plate portion 31, and the other surface serves as a counter plate portion 32.

通し材３０を野縁１２の端部に設ける場合、図２に示すように、通し材３０は、接合板部３１が対向板部３２の下側になり、対向板部３２が接合板部３１の端から立ち上がる。接合板部３１は、野縁１２の下面に当接させ、下側からビス止めすることにより、野縁１２に固定する。対向板部３２の内側面は、野縁１２の端面と隙間をあけて配置する。野縁１２の下面には天井板２０を接合し、接合板部３１の下面に天井板２０および回り縁２１の上面を当接させる。対向板部３２の外側面は、壁面５に当接しており、回り縁２１の外周端面と面一になっている。対向板部３２の外側面は、部屋の全周において、壁面５に当接している。なお、対向板部３２は、必ずしも壁面５に当接している必要はなく、僅かな隙間をあけて配置されてもよい。対向板部３２の外側面と壁面との隙間（クリアランス）は、部屋の全周において、均一であるのが好ましい。また、対向板部３２は、回り縁２１よりも壁面５側に張り出していれば、回り縁２１と面一でなくてもよい。   When the threading material 30 is provided at the end of the field edge 12, as shown in FIG. 2, the threading material 30 has the joining plate portion 31 on the lower side of the opposing plate portion 32 and the opposing plate portion 32 as the joining plate portion 31. Stand up from the edge of the. The joining plate portion 31 is fixed to the field edge 12 by contacting the lower surface of the field edge 12 and screwing from the lower side. The inner side surface of the opposing plate portion 32 is disposed with a gap from the end surface of the field edge 12. The ceiling plate 20 is bonded to the lower surface of the field edge 12, and the upper surfaces of the ceiling plate 20 and the peripheral edge 21 are brought into contact with the lower surface of the bonding plate portion 31. The outer surface of the opposing plate portion 32 is in contact with the wall surface 5 and is flush with the outer peripheral end surface of the peripheral edge 21. The outer surface of the counter plate portion 32 is in contact with the wall surface 5 on the entire circumference of the room. In addition, the opposing board part 32 does not necessarily need to contact | abut to the wall surface 5, and may be arrange | positioned with a slight clearance gap. The clearance (clearance) between the outer surface and the wall surface of the opposing plate portion 32 is preferably uniform over the entire circumference of the room. Further, the counter plate portion 32 may not be flush with the peripheral edge 21 as long as it protrudes toward the wall surface 5 from the peripheral edge 21.

通し材３０を野縁受け１２の端部に設ける場合、図３に示すように、通し材３０は、接合板部３１が対向板部３２の上側になり、対向板部３２が接合板部３１の端から垂れ下がる。接合板部３１は、野縁受け１１の上面に当接させ、上側からビス止めすることにより、野縁受け１１に固定する。対向板部３２の内側面は、野縁受け１１の端面と隙間をあけて配置する。対向板部３２の外側面は、壁面５に当接しており、下方の回り縁２１の外周端面と面一になっている。なお、対向板部３２は、必ずしも壁面５に当接している必要はなく、僅かな隙間をあけて配置されてもよい。また、対向板部３２は、回り縁２１よりも壁面５側に張り出していれば、回り縁２１と面一でなくてもよい。   When the threading material 30 is provided at the end portion of the field receiver 12, as shown in FIG. 3, the threading material 30 has the joining plate portion 31 on the upper side of the opposing plate portion 32 and the opposing plate portion 32 as the joining plate portion 31. Hangs down from the edge of The joining plate portion 31 is fixed to the field edge receiver 11 by contacting the upper surface of the field edge receiver 11 and screwing it from above. The inner side surface of the opposing plate part 32 is disposed with a gap from the end surface of the field edge receiver 11. The outer surface of the opposing plate portion 32 is in contact with the wall surface 5 and is flush with the outer peripheral end surface of the lower peripheral edge 21. In addition, the opposing board part 32 does not necessarily need to contact | abut to the wall surface 5, and may be arrange | positioned with a slight clearance gap. Further, the counter plate portion 32 may not be flush with the peripheral edge 21 as long as it protrudes toward the wall surface 5 from the peripheral edge 21.

通し材３０は、壁面５の横幅寸法より僅かに短く、壁面５の両サイドに位置する直交壁面に干渉しない長さ寸法を有している。図１の（ｂ）に示すように、Ｙ軸方向に延在する通し材３０の長手方向端部は、野縁受け１１と平行な壁面（野縁１２の端面と対向する壁面）と僅かな隙間をあけて対向している。また、Ｘ軸方向に延在する通し材３０の長手方向端部は、野縁１２と平行な壁面（野縁受け１１の端面と対向する壁面）と僅かな隙間をあけて対向している。これによって、野縁受け１１の端部に設けられた通し材３０の端部と、野縁１２の端部に設けられた通し材３０の端部とが干渉することはない。   The threading member 30 has a length dimension that is slightly shorter than the width dimension of the wall surface 5 and does not interfere with the orthogonal wall surfaces located on both sides of the wall surface 5. As shown in FIG. 1B, the longitudinal end of the threading member 30 extending in the Y-axis direction has a slight wall surface parallel to the field edge receiver 11 (the wall surface facing the end surface of the field edge 12). Opposite with a gap. Further, the longitudinal end portion of the threading member 30 extending in the X-axis direction faces a wall surface parallel to the field edge 12 (a wall surface facing the end surface of the field edge receiver 11) with a slight gap. Thus, the end of the threading material 30 provided at the end of the field edge receiver 11 and the end of the threading material 30 provided at the end of the field edge 12 do not interfere with each other.

以上のような構成の天井構造によれば、図４に示すように、地震などにより天井に揺れが生じた場合でも、壁面５に沿って設けられた通し材３０が壁面５に接触するので、天井下地構成材が局所的に壁面５に接触するのを防止できる。これによって、天井下地構成材に大きな応力が作用することはなく、天井下地構成材の座屈を防止することができる。また、壁面５に局所的な損傷が発生し難くなる。   According to the ceiling structure configured as described above, as shown in FIG. 4, even when the ceiling sways due to an earthquake or the like, the threading material 30 provided along the wall surface 5 contacts the wall surface 5. It is possible to prevent the ceiling base component from locally contacting the wall surface 5. Thus, a large stress does not act on the ceiling foundation component, and the buckling of the ceiling foundation component can be prevented. Further, local damage to the wall surface 5 is difficult to occur.

特に、本実施形態では、通し材３０は、対向板部３２を備えており、この対向板部３２が面で壁面５に接触する（面接触する）ので、天井の揺動時に壁面５に作用する応力を広く分散して、壁面５に掛かる面圧を大幅に低減することができる。したがって、壁面５への局所的な損傷の発生を抑制できる。   In particular, in the present embodiment, the threading member 30 includes a counter plate portion 32. Since the counter plate portion 32 comes into contact with the wall surface 5 (surface contact) with the surface, it acts on the wall surface 5 when the ceiling swings. The surface pressure applied to the wall surface 5 can be greatly reduced by widely dispersing the stress to be applied. Therefore, the occurrence of local damage to the wall surface 5 can be suppressed.

また、通し材３０が、壁面５から離間して配置されていた場合であっても、天井の揺動時に通し材３０が広い面積で壁面５に衝突するので、衝突力を分散させることができる。これによって、天井下地構成材（野縁受け１１または野縁１２）の座屈を防止することができるとともに、壁面５に局所的な損傷が発生し難くなる。   Further, even when the threading member 30 is disposed away from the wall surface 5, the threading member 30 collides with the wall surface 5 in a wide area when the ceiling is swung, so that the collision force can be dispersed. . As a result, buckling of the ceiling base component (the field receiver 11 or the field edge 12) can be prevented and local damage to the wall surface 5 is less likely to occur.

また、本実施形態では、天井の揺動時の水平力を壁面５で受けることになるので、天井下地材を吊り下げる上階床スラブへの負担を低減できる。さらに、このような構成によれば、水平力を上階床スラブへ伝達するためのブレースなどの部材を削減できるので、天井構造全体の軽量化を達成できる。   Moreover, in this embodiment, since the horizontal force at the time of the rocking | fluctuation of a ceiling is received by the wall surface 5, the burden to the upper floor slab which suspends a ceiling base material can be reduced. Furthermore, according to such a structure, since members, such as a brace for transmitting a horizontal force to an upper floor slab, can be reduced, weight reduction of the whole ceiling structure can be achieved.

なお、部屋の面積が大きいときなど、天井の揺動時の水平力が大きい場合は、壁面で大きい水平力を受けるために、壁面を通常の構造よりも補強する。壁面の補強は、例えばスタッドや木角材などの壁下地材の配置ピッチを細かくしたり、部材寸法を大きくしたり、壁仕上げ材を厚くしたりする。また、壁下地材の上端部と上部固定部（上階床スラブなどの構造体）との固定部分を補強してもよい。   When the horizontal force when the ceiling swings is large, such as when the area of the room is large, the wall surface is reinforced more than a normal structure in order to receive a large horizontal force on the wall surface. For reinforcement of the wall surface, for example, the arrangement pitch of wall base materials such as studs and wooden squares is made finer, the member dimensions are made larger, and the wall finishing material is made thicker. Moreover, you may reinforce the fixing | fixed part of the upper end part of a wall base material, and an upper fixing | fixed part (structures, such as an upper floor slab).

さらに、通し材３０の対向板部３２の内側面が野縁受け１１の端面と隙間をあけて配置されているので、壁面５からの応力は、対向板部３２から接合板部３１を介して、野縁受け１１または野縁１２に伝達される。このとき、接合板部３１または対向板部３２が変形するようにすれば、通し材３０においても応力を吸収できるので、天井下地構成材に作用する応力を低減することができる。   Furthermore, since the inner side surface of the counter plate portion 32 of the threading member 30 is disposed with a gap from the end surface of the field receiver 11, the stress from the wall surface 5 is transferred from the counter plate portion 32 through the bonding plate portion 31. , Transmitted to the field edge receiver 11 or the field edge 12. At this time, if the joining plate portion 31 or the counter plate portion 32 is deformed, the stress can be absorbed also in the threading member 30, so that the stress acting on the ceiling foundation constituent material can be reduced.

また、通し材３０は、対向板部３２に直交する接合板部３１を備えているので、隣り合う野縁受け１１同士または野縁１２同士の端部の位置が揃っていなくても、接合板部３１の接触位置を適宜調整することで、対向板部３２を壁面５に対して容易に平行に配置することができる。   Further, since the threading member 30 includes the joining plate portion 31 orthogonal to the opposing plate portion 32, the joining plate can be used even if the positions of the end portions of the adjacent field edge receivers 11 or the field edges 12 are not aligned. By appropriately adjusting the contact position of the portion 31, the counter plate portion 32 can be easily arranged in parallel to the wall surface 5.
