Description

本発明は、隠蔽式の空気調和機などの天井吊り下げ物を振れ止めするための振れ止め装置に関する。 The present invention relates to a steady rest device for restraining a ceiling-suspended object such as a concealed air conditioner.

従来、天井空間に隠蔽された状態に設置される空気調和機が知られている（例えば、特許文献１，２）。この隠蔽式の空気調和機は、平面視略矩形状であり、互いに平行な二つの側面のそれぞれの下部近傍位置に、吊りボルトなどのボルト部材を連結するための一対の取付片を備えている。そのような隠蔽式の空気調和機を天井空間に設置する場合、二つの側面のそれぞれに設けられている一対の取付片に対して、天井スラブなどの天井構造から垂下するボルト部材の下端部が連結される。すなわち、隠蔽式の空気調和機は、合計４本のボルト部材によって互いに平行な二つの側面の下部近傍が支持された状態で天井空間に設置される。 Conventionally, an air conditioner installed in a state of being concealed in a ceiling space is known (for example, Patent Documents 1 and 2). This concealed air conditioner has a substantially rectangular shape in a plan view, and is provided with a pair of mounting pieces for connecting bolt members such as hanging bolts at positions near the lower part of each of two parallel side surfaces. .. When such a concealed air conditioner is installed in a ceiling space, the lower end of a bolt member hanging from a ceiling structure such as a ceiling slab is attached to a pair of mounting pieces provided on each of the two side surfaces. Be connected. That is, the concealed air conditioner is installed in the ceiling space in a state where the vicinity of the lower part of the two side surfaces parallel to each other is supported by a total of four bolt members.

図１１は、隠蔽式の空気調和機３００を天井空間に設置した状態における従来の支持構造２００を示す図である。図１１に示すように、従来の支持構造２００は、天井スラブなどの天井構造３から吊りボルトなどのボルト部材２０９が垂下しており、そのボルト部材２０９の下端部において空気調和機３００を支持する構造である。空気調和機３００は、側面の下部近傍位置にボルト部材２０９を連結するための一対の取付片３１１，３１１を備えており、その一対の取付片３１１，３１１にボルト部材２０９の下端部が連結される。これにより、空気調和機３００は、天井空間に吊り下げられた状態で支持される。 FIG. 11 is a diagram showing a conventional support structure 200 in a state where the concealed air conditioner 300 is installed in the ceiling space. As shown in FIG. 11, in the conventional support structure 200, a bolt member 209 such as a hanging bolt hangs down from a ceiling structure 3 such as a ceiling slab, and the air conditioner 300 is supported at the lower end of the bolt member 209. It is a structure. The air conditioner 300 is provided with a pair of mounting pieces 311, 311 for connecting the bolt members 209 at positions near the lower portion of the side surface, and the lower end portion of the bolt member 209 is connected to the pair of mounting pieces 311, 311. To. As a result, the air conditioner 300 is supported in a suspended state in the ceiling space.

空気調和機３００がボルト部材２０９によって吊り下げられた状態に設置されると、空気調和機３００を振れ止めするためのブレース２１３がボルト部材２０９に取り付けられる。ブレース２１３は、互いに隣り合う２本のボルト部材２０９どうしを連結するように斜め方向に配置され、一方のボルト部材２０９の上部と他方のボルト部材２０９の下部とを連結固定する。隣り合う２本のボルト部材２０９，２０９の間に２本のブレース２１３が交叉配置されることにより、ボルト部材２０９，２０９が固定され、空気調和機３００を振れ止めすることができる。 When the air conditioner 300 is installed in a state of being suspended by the bolt member 209, a brace 213 for restraining the air conditioner 300 is attached to the bolt member 209. The brace 213 is arranged obliquely so as to connect two bolt members 209 adjacent to each other, and connects and fixes the upper portion of one bolt member 209 and the lower portion of the other bolt member 209. By cross-arranging the two braces 213 between the two adjacent bolt members 209 and 209, the bolt members 209 and 209 can be fixed and the air conditioner 300 can be restrained.

しかしながら、上述した従来の支持構造２００は、ブレース２１３を空気調和機３００の上面よりも高い位置でボルト部材２０９，２０９に連結する構造である。そのため、ボルト部材２０９，２０９の下部（図１１に示す領域Ｒの部分）においてブレース２１３による振れ止め効果を得られない。その結果、地震発生時にはボルト部材２０９，２０９の下部が振動し、それに伴って空気調和機３００も振動してしまうという問題がある。 However, the conventional support structure 200 described above has a structure in which the brace 213 is connected to the bolt members 209 and 209 at a position higher than the upper surface of the air conditioner 300. Therefore, the steady rest effect of the brace 213 cannot be obtained at the lower part of the bolt members 209 and 209 (the portion of the region R shown in FIG. 11). As a result, there is a problem that the lower parts of the bolt members 209 and 209 vibrate when an earthquake occurs, and the air conditioner 300 also vibrates accordingly.

特に、隠蔽式の空気調和機３００は、装置本体に対して吸気ユニットや吹出ユニットが接続され、それら各ユニットに対してさらに送風ダクトが接続されることがあり、装置本体が振動すると、装置本体と各ユニットとの接続部や、各ユニットと送風ダクトとの接続部が破損する可能性がある。 In particular, in the concealed air conditioner 300, an intake unit and a blowout unit may be connected to the device body, and a ventilation duct may be further connected to each of these units. When the device body vibrates, the device body The connection between the unit and each unit and the connection between each unit and the air duct may be damaged.

振れ止め装置１は、空気調和機１００の取付片１１１が設けられた側面１１０ａ，１１０ｂの上端近傍位置において空気調和機１００に取り付けられ、取付片１１１が設けられた側面１１０ａ，１１０ｂに対して直角方向（水平方向）に延設された保持部１１を有し、その保持部１１がボルト部材９を取付片１１１の上方位置で空気調和機１００に連結して保持することにより、ボルト部材９の振れ止め効果を発揮するように構成される。このような振れ止め装置１は、空気調和機１００に対して相対変位しないように位置決めされることが好ましい。そのため、本実施形態の振れ止め装置１は、空気調和機１００の上面に沿うように配置され、空気調和機１００の一方の側面１１０ａ（又は１１０ｂ）と係合すると共に、空気調和機１００の正面側及び背面側と係合することにより、ＸＹ平面内において空気調和機１００に対して相対変位しないように構成される。以下、このような振れ止め装置１について詳しく説明する。 The steady rest device 1 is attached to the air conditioner 100 at a position near the upper ends of the side surfaces 110a and 110b provided with the mounting pieces 111 of the air conditioner 100, and is perpendicular to the side surfaces 110a and 110b provided with the mounting pieces 111. The holding portion 11 extends in the direction (horizontal direction), and the holding portion 11 connects the bolt member 9 to the air conditioner 100 at a position above the mounting piece 111 and holds the bolt member 9. It is configured to exert a steady rest effect. It is preferable that the steady rest device 1 is positioned so as not to be displaced relative to the air conditioner 100. Therefore, the steady rest device 1 of the present embodiment is arranged along the upper surface of the air conditioner 100, engages with one side surface 110a (or 110b) of the air conditioner 100, and is in front of the air conditioner 100. By engaging with the side and the back side, it is configured so as not to be displaced relative to the air conditioner 100 in the XY plane. Hereinafter, such a steady rest device 1 will be described in detail.

振れ止め装置１は、空気調和機１００の上面に沿うように配置される帯状の平板部１０を有している。この平板部１０は、空気調和機１００の上面に対して位置決めされた状態に配置される。平板部１０の長手方向（Ｙ方向）の長さは、空気調和機１００の側面１１０ａ，１１０ｂの長さ（空気調和機本体１１０とフィルタユニット１２０とを合わせた空気調和機１００全体の側面１１０ａ，１１０ｂの長さ）と略等しく、その平板部１０の両端に空気調和機１００の正面及び背面の上端部に係合する第１係合部１２が設けられている。例えば、第１係合部１２は、平板部１０の両端部を下方に９０度折り曲げることにより形成される。このような第１係合部１２が空気調和機１００の正面及び背面の上端部に係合することにより、平板部１０は、空気調和機１００の上面においてＹ方向に相対変位しないように位置決めされる。 The steady rest device 1 has a strip-shaped flat plate portion 10 arranged along the upper surface of the air conditioner 100. The flat plate portion 10 is arranged in a state of being positioned with respect to the upper surface of the air conditioner 100. The length of the flat plate portion 10 in the longitudinal direction (Y direction) is the lengths of the side surfaces 110a and 110b of the air conditioner 100 (the side surfaces 110a of the entire air conditioner 100 including the air conditioner main body 110 and the filter unit 120). First engaging portions 12 that engage with the upper ends of the front and back surfaces of the air conditioner 100 are provided at both ends of the flat plate portion 10 which is substantially equal to the length of 110b). For example, the first engaging portion 12 is formed by bending both ends of the flat plate portion 10 downward by 90 degrees. By engaging such a first engaging portion 12 with the upper end portions of the front surface and the back surface of the air conditioner 100, the flat plate portion 10 is positioned on the upper surface of the air conditioner 100 so as not to be relatively displaced in the Y direction. To.

また、平板部１０の短尺方向（Ｘ方向）の長さ（幅）は、概ね１０〜２０ｃｍ程度に形成されると共に、長手方向両端部の幅が中央部の幅よりも大きくなるように形成される。言い換えると、平板部１０は、長手方向両端部が空気調和機１００の側面１１０ａ，１１０ｂを超えて外側に張り出すように、長手方向中央部よりも幅広に形成されている。したがって、平板部１０の中央部の端が空気調和機１００の上面１１０ｅの端に合致するように配置されると、平板部１０の両端部に設けられた幅広の部分が空気調和機１００の側面１１０ａ，１１０ｂから更に外側に張り出した棚状構造を形成する。振れ止め装置１は、その棚状構造となる部分を、ボルト部材９を保持する部分として利用する。すなわち、振れ止め装置１は、空気調和機１００の上面１１０ｅから側面１１０ａ，１１０ｂを超えて更に側方に延設される棚状の保持部１１を有しており、その保持部１１によって、取付片１１１に連結されたボルト部材９を保持するようにしている。 Further, the length (width) of the flat plate portion 10 in the short direction (X direction) is formed to be approximately 10 to 20 cm, and the width of both ends in the longitudinal direction is formed to be larger than the width of the central portion. To. In other words, the flat plate portion 10 is formed wider than the central portion in the longitudinal direction so that both ends in the longitudinal direction extend outward beyond the side surfaces 110a and 110b of the air conditioner 100. Therefore, when the central end of the flat plate portion 10 is arranged so as to coincide with the end of the upper surface 110e of the air conditioner 100, the wide portions provided at both ends of the flat plate portion 10 are the side surfaces of the air conditioner 100. A shelf-like structure that projects further outward from 110a and 110b is formed. The steady rest device 1 uses a portion having a shelf-like structure as a portion for holding the bolt member 9. That is, the steady rest device 1 has a shelf-shaped holding portion 11 extending laterally from the upper surface 110e of the air conditioner 100 beyond the side surfaces 110a and 110b, and is attached by the holding portion 11. The bolt member 9 connected to the piece 111 is held.

保持部１１には、ボルト部材９を挿通可能な挿通部１４が形成されている。挿通部１４は、ボルト部材９を挿通可能な孔であっても良いし、Ｕ字状に開放された切欠部であっても構わない。この挿通部１４は、空気調和機１００の各側面１１０ａ，１１０ｂに設けられている取付片１１１の上方に位置し、取付片１１１よりも高い位置（空気調和機１００の上面１１０ｅと略等しい位置）でボルト部材９を挿通することができる。 The holding portion 11 is formed with an insertion portion 14 through which the bolt member 9 can be inserted. The insertion portion 14 may be a hole through which the bolt member 9 can be inserted, or may be a notch portion opened in a U shape. The insertion portion 14 is located above the mounting pieces 111 provided on the side surfaces 110a and 110b of the air conditioner 100, and is higher than the mounting piece 111 (position substantially equal to the upper surface 110e of the air conditioner 100). The bolt member 9 can be inserted at.

また、平板部１０の中央部には、空気調和機１００の側面１１０ａ，１１０ｂの上端部に係合する第２係合部１３が設けられる。この第２係合部１３は、第１係合部１２と同様に、例えば平板部１０の中央部の端から延設させた折曲片を下方に９０度折り曲げることにより形成される。このような第２係合部１３は、空気調和機１００の側面１１０ａ，１１０ｂに装着されるカバー１１２を固定するための締着部材１１３の位置に対応するように設けられる。そして第２係合部１３には、締着部材１１３を挿通するための挿通部１５が予め形成されている。この挿通部１５も、上述した挿通部１４と同様に、締着部材１１３を挿通可能な孔であっても良いし、Ｕ字状に開放された切欠部であっても構わない。 Further, a second engaging portion 13 that engages with the upper ends of the side surfaces 110a and 110b of the air conditioner 100 is provided at the central portion of the flat plate portion 10. Like the first engaging portion 12, the second engaging portion 13 is formed by, for example, bending a bent piece extending from the end of the central portion of the flat plate portion 10 downward by 90 degrees. Such a second engaging portion 13 is provided so as to correspond to the position of the fastening member 113 for fixing the cover 112 mounted on the side surfaces 110a and 110b of the air conditioner 100. An insertion portion 15 for inserting the fastening member 113 is formed in advance in the second engaging portion 13. The insertion portion 15 may also be a hole through which the fastening member 113 can be inserted, or may be a notch portion opened in a U shape, similarly to the insertion portion 14 described above.

上記のように構成される振れ止め装置１は、図１に示すような態様で空気調和機１００に配置される。すなわち、振れ止め装置１は、平板部１０の下面が空気調和機１００の上面１１０ｅに沿うように配置され、平板部１０の長手方向両端部に設けられる第１係合部１２，１２が空気調和機１００の正面及び背面の上端部に係合し、且つ、平板部１０の中央部に設けられる第２係合部１３が空気調和機１００の一方の側面１１０ａ，１１０ｂの上端部に係合する状態に配置される。そのため、振れ止め装置１は、空気調和機１００に対してＸ方向及びＹ方向に相対変位しないように位置決めされた状態で設置される。 The steady rest device 1 configured as described above is arranged in the air conditioner 100 in the manner shown in FIG. That is, in the steady rest device 1, the lower surface of the flat plate portion 10 is arranged along the upper surface 110e of the air conditioner 100, and the first engaging portions 12 and 12 provided at both ends of the flat plate portion 10 in the longitudinal direction are air-conditioned. The upper end portions of the front surface and the back surface of the machine 100 are engaged, and the second engaging portion 13 provided at the central portion of the flat plate portion 10 engages with the upper end portions of the one side surfaces 110a and 110b of the air conditioner 100. Placed in the state. Therefore, the steady rest device 1 is installed in a state of being positioned so as not to be relatively displaced in the X direction and the Y direction with respect to the air conditioner 100.

また、空気調和機１００の側面１１０ａ，１１０ｂに取り付けられている複数の締着部材１１３のうち、第２係合部１３の位置に適合する締着部材１１３を予め空気調和機１００から外しておき、振れ止め装置１の平板部１０を、空気調和機１００の上面１１０ｅに沿うように配置し、且つ、第２係合部１３に設けられている挿通部１５を締着部材１１３の取付位置に適合するように配置した後、締着部材１１３を側面１１０ａ，１１０ｂに設けられている孔に挿入して締め付ける。これにより、空気調和機１００のカバー１１２を固定するための締着部材１１３は、カバー１１２と共に、振れ止め装置１の第２係合部１３を空気調和機１００に固定することができる。このように第２係合部１３を空気調和機１００の側面１１０ａ，１１０ｂに固定すると、振れ止め装置１は、空気調和機１００に対して固定されることになる。 Further, among the plurality of fastening members 113 attached to the side surfaces 110a and 110b of the air conditioner 100, the fastening member 113 that matches the position of the second engaging portion 13 is removed from the air conditioner 100 in advance. The flat plate portion 10 of the steady rest device 1 is arranged along the upper surface 110e of the air conditioner 100, and the insertion portion 15 provided in the second engaging portion 13 is located at the mounting position of the fastening member 113. After arranging them so as to fit, the fastening member 113 is inserted into the holes provided in the side surfaces 110a and 110b and tightened. As a result, the fastening member 113 for fixing the cover 112 of the air conditioner 100 can fix the second engaging portion 13 of the steady rest device 1 to the air conditioner 100 together with the cover 112. When the second engaging portion 13 is fixed to the side surfaces 110a and 110b of the air conditioner 100 in this way, the steady rest device 1 is fixed to the air conditioner 100.

また、振れ止め装置１は、上記のようにして平板部１０が空気調和機１００の上面１１０ｅに沿うように配置された状態でボルト部材９が保持部１１の挿通部１４に挿通され、保持部１１を挟んでボルト部材９の上下に予め装着しておいた２つのナット２１，２２が締め付けられることにより、保持部１１が取付片１１１よりも上方の位置でボルト部材９を保持した状態となる。そして振れ止め装置１は、空気調和機１００の側面１１０ａ，１１０ｂに設けられている取付片１１１よりも上側の位置においてボルト部材９を空気調和機１００に固定した状態となる。つまり、振れ止め装置１は、空気調和機１００に予め装着されている締着部材１１３を利用して空気調和機１００の側面１１０ａ，１１０ｂに固定することができるのである。そのため、振れ止め装置１を空気調和機１００に固定するときには、空気調和機１００の側面１１０ａ，１１０ｂに対して新たな孔を開ける必要がなく、作業効率に優れている。 Further, in the steady rest device 1, the bolt member 9 is inserted into the insertion portion 14 of the holding portion 11 in a state where the flat plate portion 10 is arranged along the upper surface 110e of the air conditioner 100 as described above, and the holding portion 1 is provided. By tightening the two nuts 21 and 22 mounted in advance above and below the bolt member 9 with the 11 in between, the holding portion 11 holds the bolt member 9 at a position above the mounting piece 111. .. The steady rest device 1 is in a state where the bolt member 9 is fixed to the air conditioner 100 at a position above the mounting pieces 111 provided on the side surfaces 110a and 110b of the air conditioner 100. That is, the steady rest device 1 can be fixed to the side surfaces 110a and 110b of the air conditioner 100 by using the fastening member 113 previously mounted on the air conditioner 100. Therefore, when the steady rest device 1 is fixed to the air conditioner 100, it is not necessary to make new holes in the side surfaces 110a and 110b of the air conditioner 100, and the work efficiency is excellent.

図２は、空気調和機１００に対して振れ止め装置１が取り付けられた状態を示す図であり、図２（ａ）はその斜視図を、図２（ｂ）はその正面図を示している。振れ止め装置１は、空気調和機本体１１０とフィルタユニット１２０とが一体的に組み付けられた状態の空気調和機１００の上面１１０ｅに沿うように配置され、平板部１０の長手方向両端部に設けられた２つの第１係合部１２，１２のうち、一方の第１係合部１２がフィルタユニット１２０の正面の上端部に係合し、他方の第１係合部１２が空気調和機本体１１０の背面の上端部に係合するように配置される。これらの第１係合部１２は、ビスなどの締着部材１９を用いて空気調和機本体１１０又はフィルタユニット１２０に対して固定するようにしても良い。 2A and 2B are views showing a state in which the steady rest device 1 is attached to the air conditioner 100, FIG. 2A shows a perspective view thereof, and FIG. 2B shows a front view thereof. .. The steady rest device 1 is arranged along the upper surface 110e of the air conditioner 100 in a state where the air conditioner main body 110 and the filter unit 120 are integrally assembled, and is provided at both ends in the longitudinal direction of the flat plate portion 10. Of the two first engaging portions 12, 12, one first engaging portion 12 engages with the upper end portion of the front surface of the filter unit 120, and the other first engaging portion 12 is the air conditioner main body 110. It is arranged so as to engage with the upper end of the back surface of the. These first engaging portions 12 may be fixed to the air conditioner main body 110 or the filter unit 120 by using a fastening member 19 such as a screw.

また、平板部１０の中央部に設けられた第２係合部１３は、空気調和機１００の側面１１０ａ，１１０ｂに接合するように配置され、締着部材１１３が締め付けられることにより、空気調和機１００の側面１１０ａ，１１０ｂに固定される。これにより、振れ止め装置１は、空気調和機１００に対して固定される。 Further, the second engaging portion 13 provided in the central portion of the flat plate portion 10 is arranged so as to be joined to the side surfaces 110a and 110b of the air conditioner 100, and the fastening member 113 is tightened to tighten the air conditioner. It is fixed to the side surfaces 110a and 110b of 100. As a result, the steady rest device 1 is fixed to the air conditioner 100.

そして振れ止め装置１の平板部１０から側方に張り出した保持部１１の挿通部１４に挿通されたボルト部材９が２つのナット２１，２２によって保持部１１に固定されると、振れ止め装置１は、図２（ａ）及び（ｂ）に示すように、取付片１１１の上方位置（空気調和機１００の上面近傍位置）でボルト部材９を空気調和機１００に固定することができる。 Then, when the bolt member 9 inserted into the insertion portion 14 of the holding portion 11 projecting laterally from the flat plate portion 10 of the steady rest device 1 is fixed to the holding portion 11 by the two nuts 21 and 22, the steady rest device 1 Can fix the bolt member 9 to the air conditioner 100 at a position above the mounting piece 111 (a position near the upper surface of the air conditioner 100) as shown in FIGS. 2A and 2B.

図３は、振れ止め装置１を用いて空気調和機１００を天井空間に設置した状態における支持構造３０を示す図である。図３に示すように、この支持構造３０は、天井スラブなどの天井構造３から吊りボルトなどのボルト部材９が垂下しており、そのボルト部材９の下端部が空気調和機１００の取付片１１１に連結され、空気調和機１００を吊り下げた状態で支持する構造である。 FIG. 3 is a diagram showing a support structure 30 in a state where the air conditioner 100 is installed in the ceiling space using the steady rest device 1. As shown in FIG. 3, in the support structure 30, a bolt member 9 such as a hanging bolt hangs down from the ceiling structure 3 such as a ceiling slab, and the lower end of the bolt member 9 is a mounting piece 111 of the air conditioner 100. It is a structure that is connected to and supports the air conditioner 100 in a suspended state.

図３に示すように、空気調和機１００がボルト部材９によって吊り下げられた状態に設置されると、空気調和機１００を振れ止めするためのブレース３２がボルト部材９に取り付けられる。例えば、ボルト部材９の上部（天井構造３の近傍位置）及び下部（空気調和機１００の上面近傍位置）にブレース連結部材３１が取り付けられ、ブレース３２の端部がそのブレース連結部材３１に連結されることにより、ブレース３２は、ボルト部材９に取り付けられる。ブレース３２は、互いに隣り合う２本のボルト部材９どうしを連結するように斜め方向に配置され、一方のボルト部材９の上部と他方のボルト部材９の下部とを連結する。隣り合う２本のボルト部材９，９の間に２本のブレース３２が交叉配置されることにより、２つのボルト部材９，９が相対変位しないように固定され、上下２つのブレース連結部材３１の間に位置するボルト部材９の振動を抑制することができる。 As shown in FIG. 3, when the air conditioner 100 is installed in a state of being suspended by the bolt member 9, a brace 32 for restraining the air conditioner 100 is attached to the bolt member 9. For example, the brace connecting member 31 is attached to the upper portion (position near the ceiling structure 3) and the lower portion (position near the upper surface of the air conditioner 100) of the bolt member 9, and the end portion of the brace 32 is connected to the brace connecting member 31. As a result, the brace 32 is attached to the bolt member 9. The brace 32 is arranged obliquely so as to connect two bolt members 9 adjacent to each other, and connects the upper portion of one bolt member 9 and the lower portion of the other bolt member 9. By cross-arranging the two brace 32s between the two adjacent bolt members 9 and 9, the two bolt members 9 and 9 are fixed so as not to be relatively displaced, and the upper and lower brace connecting members 31 The vibration of the bolt member 9 located between them can be suppressed.

また、空気調和機１００の上面１１０ｅに沿うように設置した振れ止め装置１は、取付片１１１と振れ止め装置１（より厳密には保持部１１）との間においてボルト部材９が相対変位することを抑制する。つまり、振れ止め装置１は、ブレース連結部材３１よりも下側において、ボルト部材９を取付片１１１とは異なる高さ位置で空気調和機１００に固定しているため、空気調和機１００の側方の上下２箇所でボルト部材９を位置決めすることができ、ブレース連結部材３１の下方においてボルト部材９の下部（図３に示す領域Ｌの部分）が振動することを抑制することができるのである。その結果、地震発生時においても、ボルト部材９の下部が振動することを抑制することができ、空気調和機１００の振動を有効に抑えることができるという利点がある。 Further, in the steady rest device 1 installed along the upper surface 110e of the air conditioner 100, the bolt member 9 is relatively displaced between the mounting piece 111 and the steady rest device 1 (more strictly, the holding portion 11). Suppress. That is, since the steady rest device 1 fixes the bolt member 9 to the air conditioner 100 at a height position different from that of the mounting piece 111 on the lower side of the brace connecting member 31, the side of the air conditioner 100 The bolt member 9 can be positioned at two positions above and below the brace connecting member 31, and the lower part of the bolt member 9 (the portion of the region L shown in FIG. 3) can be suppressed from vibrating below the brace connecting member 31. As a result, even when an earthquake occurs, it is possible to suppress the vibration of the lower portion of the bolt member 9, and there is an advantage that the vibration of the air conditioner 100 can be effectively suppressed.

上記のような振れ止め装置１は、空気調和機１００を天井構造３の高さ位置まで持ち上げる前に、予め床面上の作業で予め空気調和機１００に取り付けておくことが可能である。そのため、振れ止め装置１を予め床面上で空気調和機１００に取り付けておけば、高所作業の負担を軽減することができる。 The steady rest device 1 as described above can be attached to the air conditioner 100 in advance by working on the floor surface before the air conditioner 100 is lifted to the height position of the ceiling structure 3. Therefore, if the steady rest device 1 is attached to the air conditioner 100 in advance on the floor surface, the burden of work in high places can be reduced.

また上述した振れ止め装置１は、フィルタユニット１２０が空気調和機本体１１０に装着された状態において平板部１０の両端部に設けた２つの第１係合部１２，１２がフィルタユニット１２０と空気調和機本体１１０との双方に係合する。そのため、振れ止め装置１は、空気調和機本体１１０だけでなく、空気調和機本体１１０とフィルタユニット１２０との双方を振れ止めする効果を発揮する。 Further, in the above-mentioned steady rest device 1, two first engaging portions 12, 12 provided at both ends of the flat plate portion 10 are air-conditioned with the filter unit 120 in a state where the filter unit 120 is mounted on the air conditioner main body 110. Engage with both the machine body 110. Therefore, the steady rest device 1 exerts an effect of steady resting not only the air conditioner main body 110 but also both the air conditioner main body 110 and the filter unit 120.

ところで、空気調和機本体１１０に装着されるフィルタユニット１２０の正面サイズ（ＸＺ平面のサイズ）は、空気調和機本体１１０の正面サイズと異なることがある。そのような場合、振れ止め装置１は、平板部１０の両端部に設けている２つの保持部１１のうち、フィルタユニット１２０の正面上端部に係合する第１係合部１２が設けられている保持部１１をフィルタユニット１２０の正面サイズに応じて途中で屈曲させたものを用いれば良い。 By the way, the front size (size of the XZ plane) of the filter unit 120 mounted on the air conditioner main body 110 may be different from the front size of the air conditioner main body 110. In such a case, the steady rest device 1 is provided with a first engaging portion 12 that engages with the front upper end portion of the filter unit 120 among the two holding portions 11 provided at both ends of the flat plate portion 10. The holding portion 11 may be bent in the middle according to the front size of the filter unit 120.

図４は、フィルタユニット１２０の正面サイズが空気調和機本体１１０の正面サイズと異なる空気調和機１００に取り付けられる振れ止め装置１を示す図である。図４の例では、フィルタユニット１２０の正面サイズが空気調和機本体１１０の正面サイズよりも大きい場合を示している。この場合の振れ止め装置１は、空気調和機本体１１０に装着されているフィルタユニット１２０の装着部１２２の近傍位置に屈曲部１８が設けられ、その屈曲部１８よりも先端部分がフィルタユニット１２０の上面に沿うように配置される。この屈曲部１８の高さは、フィルタユニット１２０のサイズに応じて適宜設計すれば良い。このように平板部１０（又は保持部１１）に屈曲部１８を設けることにより、振れ止め装置１は、フィルタユニット１２０と空気調和機本体１１０とのサイズが互いに異なる場合であっても、平板部１０をそれぞれの上面に沿うように配置することができる。そのため、振れ止め装置１が空気調和機１００に固定されると、振れ止め装置１は、空気調和機１００と一体的な天井吊り下げ物となる。 FIG. 4 is a diagram showing a steady rest device 1 attached to an air conditioner 100 in which the front size of the filter unit 120 is different from the front size of the air conditioner main body 110. In the example of FIG. 4, the front size of the filter unit 120 is larger than the front size of the air conditioner main body 110. In this case, the steady rest device 1 is provided with a bent portion 18 near the mounting portion 122 of the filter unit 120 mounted on the air conditioner main body 110, and the tip portion of the filter unit 120 is more than the bent portion 18. It is arranged along the upper surface. The height of the bent portion 18 may be appropriately designed according to the size of the filter unit 120. By providing the bent portion 18 in the flat plate portion 10 (or the holding portion 11) in this way, the steady rest device 1 can be used even when the size of the filter unit 120 and the size of the air conditioner main body 110 are different from each other. 10 can be arranged along the upper surface of each. Therefore, when the steady rest device 1 is fixed to the air conditioner 100, the steady rest device 1 becomes a ceiling suspension object integrated with the air conditioner 100.

図５は、振れ止め装置１を用いてフィルタユニット１２０と空気調和機本体１１０のサイズが異なる空気調和機１００を天井空間に設置した状態における支持構造３０を示す図である。図５に示すように、振れ止め装置１に屈曲部１８を設けることにより、振れ止め装置１は、平板部１０をフィルタユニット１２０と空気調和機本体１１０との双方の上面に沿うように配置することができる。そのため、振れ止め装置１は、フィルタユニット１２０と空気調和機本体１１０のサイズが異なる場合であっても、空気調和機本体１１０とフィルタユニット１２０との双方を有効に振れ止めすることが可能である。 FIG. 5 is a diagram showing a support structure 30 in a state where the filter unit 120 and the air conditioner 100 having different sizes of the air conditioner main body 110 are installed in the ceiling space by using the steady rest device 1. As shown in FIG. 5, by providing the steady rest device 1 with a bent portion 18, the steady rest device 1 arranges the flat plate portion 10 along the upper surfaces of both the filter unit 120 and the air conditioner main body 110. be able to. Therefore, the steady rest device 1 can effectively steady both the air conditioner main body 110 and the filter unit 120 even when the sizes of the filter unit 120 and the air conditioner main body 110 are different. ..

次に図６は、フィルタユニット１２０の正面側に吸気ユニット１３０が配置され、空気調和機本体１１０の背面側に吹出ユニット１４０が配置された空気調和機１００を例示する図である。上述した振れ止め装置１は、例えば板厚が数ミリメートル程度の比較的薄い金属板を加工して形成されるため、平板部１０の両端部に設けられている第１係合部１２が空気調和機本体１１０及びフィルタユニット１２０の上端部に係合している場合であっても、フィルタユニット１２０の正面側に吸気ユニット１３０を適切に配置することができ、また空気調和機本体１１０の背面側に吹出ユニット１４０を適切に配置することができる。このとき、第１係合部１２は、フィルタユニット１２０と吸気ユニット１３０との間、又は、空気調和機本体１１０と吹出ユニット１４０との間に挟まれた状態で固定される。そのため、第１係合部１２は、上述した締着部材１９を用いて空気調和機本体１１０又はフィルタユニット１２０に固定する必要がない。上述した振れ止め装置１は、フィルタユニット１２０の正面側に吸気ユニット１３０が配置される場合、又は、空気調和機本体１１０の背面側に吹出ユニット１４０が配置される場合であっても、有効に使用することができる。 Next, FIG. 6 is a diagram illustrating an air conditioner 100 in which the intake unit 130 is arranged on the front side of the filter unit 120 and the blowout unit 140 is arranged on the back side of the air conditioner main body 110. Since the steady rest device 1 described above is formed by processing a relatively thin metal plate having a plate thickness of, for example, about several millimeters, the first engaging portions 12 provided at both ends of the flat plate portion 10 are air-conditioned. The intake unit 130 can be appropriately arranged on the front side of the filter unit 120 even when it is engaged with the upper ends of the machine body 110 and the filter unit 120, and the rear side of the air conditioner body 110. The blowout unit 140 can be appropriately arranged. At this time, the first engaging portion 12 is fixed in a state of being sandwiched between the filter unit 120 and the intake unit 130, or between the air conditioner main body 110 and the blowout unit 140. Therefore, it is not necessary to fix the first engaging portion 12 to the air conditioner main body 110 or the filter unit 120 by using the above-mentioned tightening member 19. The above-mentioned steady rest device 1 is effective even when the intake unit 130 is arranged on the front side of the filter unit 120 or the blowout unit 140 is arranged on the back side of the air conditioner main body 110. Can be used.

図７は、空気調和機本体１１０、フィルタユニット１２０、吸気ユニット１３０及び吹出ユニット１４０が一体的に組み付けられた空気調和機１００を支持するフレーム枠体４０を例示する図である。フレーム枠体４０は、空気調和機本体１１０、フィルタユニット１２０、吸気ユニット１３０及び吹出ユニット１４０を一体的に組み付けた空気調和機１００を支持する装置である。このフレーム枠体４０は、複数の上段フレーム材４１，４２，４３，４４と、複数の下段フレーム材４５，４６とが井桁状に組み付けられて構成される矩形状の金属枠体である。各フレーム材４１〜４６には、長手方向に沿って上下に貫通するスリット４８が形成されており、そのスリット４８の任意の位置にボルト部材を差し込むことができる。 FIG. 7 is a diagram illustrating a frame frame 40 that supports an air conditioner 100 in which an air conditioner main body 110, a filter unit 120, an intake unit 130, and a blowout unit 140 are integrally assembled. The frame frame 40 is a device that supports the air conditioner 100 in which the air conditioner main body 110, the filter unit 120, the intake unit 130, and the blowout unit 140 are integrally assembled. The frame frame 40 is a rectangular metal frame formed by assembling a plurality of upper frame members 41, 42, 43, 44 and a plurality of lower frame members 45, 46 in a grid shape. Slits 48 that penetrate vertically along the longitudinal direction are formed in each of the frame members 41 to 46, and a bolt member can be inserted at an arbitrary position of the slits 48.

上段フレーム材４１，４２，４３，４４及び下段フレーム材４５，４６は、直交連結金具５１によって互いに直交する状態に固定される。直交連結金具５１は、上段フレーム材４１，４２，４３，４４のスリット４８と、下段フレーム材４５，４６のスリット４８に挿通したボルト部材にナットを装着し、そのナットで締め付けることにより、上段フレーム材４１，４２，４３，４４と下段フレーム材４５，４６とを直交させた状態に固定する金具である。直交連結金具５１のボルト部材とナットとを緩めると、上段フレーム材４１，４２，４３，４４及び下段フレーム材４５，４６が交叉する位置を調整することが可能であり、フレーム枠体４０の矩形サイズを調整することができる。 The upper frame members 41, 42, 43, 44 and the lower frame members 45, 46 are fixed in a state orthogonal to each other by the orthogonal connecting metal fitting 51. The orthogonal connecting metal fitting 51 is formed by attaching nuts to the slits 48 of the upper frame members 41, 42, 43, 44 and the bolt members inserted into the slits 48 of the lower frame members 45, 46 and tightening them with the nuts to tighten the upper frame. It is a metal fitting for fixing the members 41, 42, 43, 44 and the lower frame members 45, 46 in an orthogonal state. By loosening the bolt member and the nut of the orthogonal connecting metal fitting 51, it is possible to adjust the position where the upper frame members 41, 42, 43, 44 and the lower frame members 45, 46 intersect, and the rectangular shape of the frame frame 40. You can adjust the size.

例えば、下段フレーム材４５，４６は、空気調和機１００の長手方向（Ｙ方向）の長さと同程度の長さを有しており、互いの間隔が空気調和機１００の幅方向（Ｘ方向）の長さと同程度となるように配置される。上段フレーム材４１，４２，４３，４４は、下段フレーム材４５，４６の上側に配置される。上段フレーム材４１，４２，４３，４４のうち、２つの上段フレーム材４１，４４は、空気調和機１００の幅方向（Ｘ方向）の長さと同程度の長さを有しており、互いの間隔が空気調和機１００の長手方向（Ｙ方向）の長さと同程度となるように配置される。また残りの２つの上段フレーム材４２，４３は、空気調和機１００の幅方向（Ｘ方向）の長さよりも長く形成されており、互いの間隔が吊りボルトなどのボルト部材９の設置間隔に合致する間隔に配置される。 For example, the lower frame members 45 and 46 have a length similar to the length in the longitudinal direction (Y direction) of the air conditioner 100, and the distance between them is the width direction (X direction) of the air conditioner 100. It is arranged so as to be about the same length as. The upper frame members 41, 42, 43, 44 are arranged above the lower frame members 45, 46. Of the upper frame materials 41, 42, 43, 44, the two upper frame materials 41, 44 have a length similar to the length in the width direction (X direction) of the air conditioner 100, and have a mutual length. The intervals are arranged so as to be approximately the same as the length in the longitudinal direction (Y direction) of the air conditioner 100. Further, the remaining two upper frame members 42 and 43 are formed longer than the length in the width direction (X direction) of the air conditioner 100, and the distance between them matches the installation distance of the bolt member 9 such as a hanging bolt. Are placed at intervals.

上記のようなフレーム枠体４０は、下段フレーム材４５，４６のスリット４８に空気調和機１００を支持するボルト部材５５，５６が装着されると共に、上段フレーム材４２，４３のスリット４８に吊りボルトなどのボルト部材９を連結するための連結部５２が装着される。図７の例では、連結部５２に防振ハンガーが用いられる場合を示している。防振ハンガーは、空気調和機１００の運転中に発生する振動をボルト部材９に伝達しないようにしてフレーム枠体４０とボルト部材９とを連結する金具であり、箱形枠体の下端が上段フレーム材４２，４３に固定されており、箱形枠体の内部に設けられたスプリングバネなどの弾性部材に対してボルト部材９の下端部が接続される。つまり、防振ハンガーは、弾性部材が振動を吸収することで、空気調和機１００の振動をボルト部材９に伝達させないようにしている。 In the frame frame 40 as described above, bolt members 55 and 56 for supporting the air conditioner 100 are attached to the slits 48 of the lower frame members 45 and 46, and hanging bolts are attached to the slits 48 of the upper frame members 42 and 43. A connecting portion 52 for connecting the bolt members 9 such as the above is mounted. In the example of FIG. 7, a case where an anti-vibration hanger is used for the connecting portion 52 is shown. The anti-vibration hanger is a metal fitting that connects the frame frame 40 and the bolt member 9 so as not to transmit the vibration generated during the operation of the air conditioner 100 to the bolt member 9, and the lower end of the box-shaped frame is the upper stage. The lower end portion of the bolt member 9 is connected to an elastic member such as a spring spring provided inside the box-shaped frame body which is fixed to the frame members 42 and 43. That is, in the anti-vibration hanger, the elastic member absorbs the vibration so that the vibration of the air conditioner 100 is not transmitted to the bolt member 9.

尚、連結部５２は、防振ハンガーを用いるものに限られない。すなわち、連結部５２は、吊りボルトなどのボルト部材９をフレーム枠体４０に連結することができればどのような構造であっても構わない。 The connecting portion 52 is not limited to the one using the anti-vibration hanger. That is, the connecting portion 52 may have any structure as long as the bolt member 9 such as a hanging bolt can be connected to the frame frame body 40.

下段フレーム材４５，４６に装着されるボルト部材５５は、その下端部が空気調和機１００の側面１１０ａ，１１０ｂに設けられている取付片１１１に連結され、取付片１１１よりも上方の位置が振れ止め装置１によって保持され、空気調和機１００の上面と略同じ高さ位置で空気調和機１００に固定される。したがって、地震が発生したとしても、フレーム枠体４０から垂下するボルト部材５５は、振動することがない。 The lower end of the bolt member 55 mounted on the lower frame members 45 and 46 is connected to the mounting pieces 111 provided on the side surfaces 110a and 110b of the air conditioner 100, and the position above the mounting pieces 111 swings. It is held by the stop device 1 and fixed to the air conditioner 100 at a position substantially the same height as the upper surface of the air conditioner 100. Therefore, even if an earthquake occurs, the bolt member 55 hanging from the frame body 40 does not vibrate.

また下段フレーム材４５，４６に装着されるボルト部材５６は、吸気ユニット１３０及び吹出ユニット１４０のそれぞれの上面に連結され、吸気ユニット１３０及び吹出ユニット１４０を支持する。このボルト部材５６は、ボルト部材５５と比較すると長さが短いため、地震発生時において大きく振動することはない。 Further, the bolt members 56 attached to the lower frame members 45 and 46 are connected to the upper surfaces of the intake unit 130 and the blowout unit 140, respectively, and support the intake unit 130 and the blowout unit 140. Since the bolt member 56 has a shorter length than the bolt member 55, it does not vibrate significantly when an earthquake occurs.

したがって、空気調和機１００の吸気ユニット１３０や吹出ユニット１４０に対してさらに送風ダクトが接続されるとしても、空気調和機１００の振動を抑えることができるので、吸気ユニット１３０と送風ダクトとの接続部又は吹出ユニット１４０と送風ダクトとの接続部が破損することはない。 Therefore, even if the air conditioner 100 is further connected to the air intake unit 130 and the air outlet unit 140, the vibration of the air conditioner 100 can be suppressed, so that the connection portion between the air conditioner 130 and the air duct can be suppressed. Alternatively, the connection between the blowout unit 140 and the air duct will not be damaged.

上記のようなフレーム枠体４０は、床面上の作業で空気調和機１００に取り付けておくことができる。そのため、床面上の作業でフレーム枠体４０を予め空気調和機１００に組み付けた後、昇降機などを用いてフレーム枠体４０と空気調和機１００とを一体的に天井構造３の近傍位置まで持ち上げ、連結部５２に対して天井構造３から垂下する吊りボルトなどのボルト部材９を連結することにより、空気調和機１００を天井空間に設置することができる。このとき、連結部５２の位置がボルト部材９の位置に合致しなければ、連結部５２の取付位置をＸ方向に移動させたり、或いは、上段フレーム材４２，４３の取付位置をＹ方向に移動させたりすることにより、連結部５２とボルト部材９との位置を簡単に合致させることができる。そのため、空気調和機１００を天井空間に設置する際の高所作業を効率的に行うことができるという利点がある。 The frame frame 40 as described above can be attached to the air conditioner 100 by working on the floor surface. Therefore, after assembling the frame frame 40 to the air conditioner 100 in advance by working on the floor surface, the frame frame 40 and the air conditioner 100 are integrally lifted to a position near the ceiling structure 3 by using an elevator or the like. The air conditioner 100 can be installed in the ceiling space by connecting a bolt member 9 such as a hanging bolt hanging from the ceiling structure 3 to the connecting portion 52. At this time, if the position of the connecting portion 52 does not match the position of the bolt member 9, the mounting position of the connecting portion 52 is moved in the X direction, or the mounting positions of the upper frame members 42 and 43 are moved in the Y direction. By making them match, the positions of the connecting portion 52 and the bolt member 9 can be easily matched. Therefore, there is an advantage that the aerial work when installing the air conditioner 100 in the ceiling space can be efficiently performed.

図８は、フレーム枠体４０を用いて空気調和機１００を天井空間に設置した状態における支持構造３０を示す図である。図８に示すように、振れ止め装置１を用いてボルト部材５５が固定された空気調和機１００を、フレーム枠体４０を用いて天井空間に設置することにより、吸気ユニット１３０又は吹出ユニット１４０の上方に梁２１０や配管２２０などの障害物が存在する場合であっても、空気調和機１００を適切な位置に設置することが可能であるという利点がある。 FIG. 8 is a diagram showing a support structure 30 in a state where the air conditioner 100 is installed in the ceiling space using the frame frame 40. As shown in FIG. 8, by installing the air conditioner 100 to which the bolt member 55 is fixed by using the steady rest device 1 in the ceiling space using the frame frame 40, the intake unit 130 or the blowout unit 140 There is an advantage that the air conditioner 100 can be installed at an appropriate position even when an obstacle such as a beam 210 or a pipe 220 is present above.

以上、本発明の一実施形態について説明したが、本発明は、上記実施形態において説明したものに限定されるものではない。すなわち、本発明には、上記実施形態において説明したものに種々の変形例を適用したものの含まれる。 Although one embodiment of the present invention has been described above, the present invention is not limited to the one described in the above embodiment. That is, the present invention includes those to which various modifications are applied to those described in the above embodiment.

例えば、上記実施形態においては、振れ止め装置１が、主として、空気調和機本体１１０とフィルタユニット１２０との上面に沿うように配置される場合を例示した。しかし、上述したように吸気ユニット１３０や吹出ユニット１４０が装着される場合、振れ止め装置１は、平板部１０を長手方向に更に長くし、吸気ユニット１３０や吹出ユニット１４０の上面にも沿うように配置されるようにしても良い。この場合、第１係合部１２は、吸気ユニット１３０や吹出ユニット１４０の上端部に係合するように配置される構成とすれば良い。また、振れ止め装置１は、空気調和機本体１１０の上面だけに配置される構造であっても構わない。 For example, in the above embodiment, the case where the steady rest device 1 is arranged mainly along the upper surface of the air conditioner main body 110 and the filter unit 120 has been illustrated. However, when the intake unit 130 or the blowout unit 140 is mounted as described above, the steady rest device 1 further lengthens the flat plate portion 10 in the longitudinal direction so as to follow the upper surface of the intake unit 130 or the blowout unit 140. It may be arranged. In this case, the first engaging portion 12 may be arranged so as to engage with the upper end portions of the intake unit 130 and the blowing unit 140. Further, the steady rest device 1 may have a structure arranged only on the upper surface of the air conditioner main body 110.

また、上記実施形態では、平板部１０の両端部に第１係合部１２が設けられると共に、平板部１０の中央部に第２係合部１３が設けられる場合を例示した。これら第１係合部１２及び第２係合部１３は、振れ止め装置１が空気調和機１００に対して相対変位しないように位置決めするためのものである。しかし、平板部１０が例えばビスなどの締着部材を用いて空気調和機１００の上面に固定される場合は、第１係合部１２及び第２係合部１３を設けることは必須ではない。 Further, in the above embodiment, the case where the first engaging portion 12 is provided at both ends of the flat plate portion 10 and the second engaging portion 13 is provided at the central portion of the flat plate portion 10 is illustrated. The first engaging portion 12 and the second engaging portion 13 are for positioning the steady rest device 1 so as not to be displaced relative to the air conditioner 100. However, when the flat plate portion 10 is fixed to the upper surface of the air conditioner 100 by using a fastening member such as a screw, it is not essential to provide the first engaging portion 12 and the second engaging portion 13.

また、上記実施形態で説明した振れ止め装置１は、取付片１１１と保持部１１との間でボルト部材９に装着され、空気調和機１００の側面１１０ａ，１１０ｂに係合する係合部材を備えるものであっても良い。図９及び図１０は、そのような係合部材６０を備える振れ止め装置１の例を示す図である。この振れ止め装置１は、図９に示すように保持部１１の下方においてボルト部材９に装着される係合部材６０を備えている。この係合部材６０は、例えば、ＸＹ平面内に配置される横板部６２とＹＺ平面内に配置される縦板部５３とを備える概略Ｌ字状の係合金具６１と、２つのナット５４，５５とによって構成される。横板部６２には、ボルト部材９を挿通する挿通部６４が設けられる。この挿通部６４は、孔であっても良いし、Ｕ字状に開放された切欠部であっても良い。挿通部６４にボルト部材９が挿通され、横板部６２を挟んで上下に２つのナット６５，６６が締着されると、縦板部６３は、空気調和機１００の側面１１０ａ，１１０ｂと接合した状態となる。すなわち、係合部材６０が装着されると、図１０に示すように係合部材６０は、縦板部６３を空気調和機１００の側面１１０ａ，１１０ｂに押し当てた状態となる。そのため、このような係合部材６０を用いれば、ボルト部材９のＸ方向の振動を防止することができる。また、このような係合部材６０は、上述した第２係合１３の代わりに用いることもできる。そのため、図９及び図１０に示すような係合部材６０を使用する場合には、平板部１０に対して上述した第２係合部１３を設けなくても良い。 Further, the steady rest device 1 described in the above embodiment includes an engaging member that is mounted on the bolt member 9 between the mounting piece 111 and the holding portion 11 and engages with the side surfaces 110a and 110b of the air conditioner 100. It may be a thing. 9 and 10 are views showing an example of a steady rest device 1 provided with such an engaging member 60. As shown in FIG. 9, the steady rest device 1 includes an engaging member 60 mounted on the bolt member 9 below the holding portion 11. The engaging member 60 includes, for example, a substantially L-shaped engaging metal fitting 61 including a horizontal plate portion 62 arranged in the XY plane and a vertical plate portion 53 arranged in the YZ plane, and two nuts 54. , 55. The horizontal plate portion 62 is provided with an insertion portion 64 through which the bolt member 9 is inserted. The insertion portion 64 may be a hole or a notch portion opened in a U shape. When the bolt member 9 is inserted through the insertion portion 64 and the two nuts 65 and 66 are fastened up and down with the horizontal plate portion 62 interposed therebetween, the vertical plate portion 63 is joined to the side surfaces 110a and 110b of the air conditioner 100. It will be in the state of. That is, when the engaging member 60 is attached, as shown in FIG. 10, the engaging member 60 is in a state where the vertical plate portion 63 is pressed against the side surfaces 110a and 110b of the air conditioner 100. Therefore, by using such an engaging member 60, it is possible to prevent the bolt member 9 from vibrating in the X direction. Further, such an engaging member 60 can be used instead of the above-mentioned second engaging member 13. Therefore, when the engaging member 60 as shown in FIGS. 9 and 10 is used, it is not necessary to provide the above-mentioned second engaging portion 13 with respect to the flat plate portion 10.

また、上記実施形態では、天井吊り下げ物の一例として空気調和機１００を例示した。しかし、上述した振れ止め装置１を適用可能な天井吊り下げ物は、空気調和機１００に限られない。すなわち、天井吊り下げ物は、平面視略矩形状であり、互いに平行な側面のそれぞれの下部近傍に、ボルト部材９を連結するための取付片１１１が設けられているものであれば良い。 Further, in the above embodiment, the air conditioner 100 is illustrated as an example of the ceiling-suspended object. However, the ceiling suspension to which the above-mentioned steady rest device 1 can be applied is not limited to the air conditioner 100. That is, the ceiling-suspended object may have a substantially rectangular shape in a plan view, and may be provided with mounting pieces 111 for connecting the bolt members 9 in the vicinity of the lower portions of the side surfaces parallel to each other.

また、上記実施形態では、空気調和機１００の左右両側に設置される一対の振れ止め部材１ａ，１ｂがそれぞれ別体として構成される場合を例示した。しかし、これに限られるものではなく、一対の振れ止め部材１ａ，１ｂを一体化した構造として実現しても良い。 Further, in the above embodiment, a case where the pair of steady rest members 1a and 1b installed on the left and right sides of the air conditioner 100 are configured as separate bodies has been illustrated. However, the present invention is not limited to this, and a pair of steady rest members 1a and 1b may be realized as an integrated structure.

また、上記実施形態では、空気調和機１００が設置される天井構造の一例として天井スラブを例示した。しかし、空気調和機１００が設置される天井構造は、必ずしも天井スラブに限られない。例えば、天井空間に鋼材などが組み付けられて構成される構造物などが存在する場合は、そのような構造物などに対して空気調和機１００が設置されるものであっても構わない。 Further, in the above embodiment, the ceiling slab is exemplified as an example of the ceiling structure in which the air conditioner 100 is installed. However, the ceiling structure in which the air conditioner 100 is installed is not necessarily limited to the ceiling slab. For example, if there is a structure or the like in which a steel material or the like is assembled in the ceiling space, the air conditioner 100 may be installed in such a structure or the like.
