Embodiment 1 FIG.
1 is a side view showing a ceiling work curing apparatus according to Embodiment 1 of the present invention, FIG. 2 is a perspective view showing the ceiling work curing apparatus of FIG. 1, and FIG. 3 is a diagram of the ceiling work curing apparatus of FIG. FIG. In the figure, an opening 11 is formed in the ceiling 1. The ceiling 1 is provided with an air conditioning indoor unit (work target member) 2 inserted into the opening 11. The air conditioning indoor unit 2 is suspended by a pair of bolts 3 fixed to the building.

天井作業用養生装置は、ボルト3に吊下げられる一対の吊り部材4と、上部につり部材4が設けられた側壁部5と、側壁部5に設けられた底面部6とを有している。   The curing apparatus for ceiling work has a pair of suspension members 4 suspended from the bolts 3, a side wall portion 5 provided with a suspension member 4 on the upper portion, and a bottom surface portion 6 provided on the side wall portion 5. .

それぞれの吊り部材4は、ボルト3と係合するフック部41と、フック部41と側壁部5とを連結するワイヤ部42とを有している。   Each suspension member 4 includes a hook portion 41 that engages with the bolt 3, and a wire portion 42 that connects the hook portion 41 and the side wall portion 5.

側壁部5は、開口部11から下方に延びた領域7を囲むように形成されている。また、側壁部5は、内部に窒素(気体)が出し入れ可能な風船から構成されている。つまり、側壁部5は、内部に気体が出し入れされることによって高さ方向について伸縮する。   The side wall 5 is formed so as to surround a region 7 extending downward from the opening 11. Moreover, the side wall part 5 is comprised from the balloon which can take in and out nitrogen (gas) inside. That is, the side wall part 5 expands and contracts in the height direction when gas is taken in and out.

側壁部5は、内部に窒素が入れられることによって高さ方向に延びて、側壁部5の形状が円筒形状となる。また、側壁部5の内部に窒素が入れられることによって、側壁部5がシートから構成されている場合と比較して、側壁部5の剛性が強くなる。   The side wall 5 extends in the height direction when nitrogen is introduced therein, and the shape of the side wall 5 becomes a cylindrical shape. In addition, when nitrogen is introduced into the side wall part 5, the rigidity of the side wall part 5 becomes stronger as compared with the case where the side wall part 5 is formed of a sheet.

側壁部5は、内部から窒素が出されることによって高さ方向について収縮する。また、側壁部5は、内部から窒素が出されることによって、側壁部5の内部に窒素が入れられている場合と比較して、側壁部5の剛性が弱くなる。これにより、側壁部5を容易に折り畳むことができる。   The side wall 5 contracts in the height direction when nitrogen is extracted from the inside. Moreover, the side wall part 5 is weakened in rigidity as compared with the case where nitrogen is put into the side wall part 5 by nitrogen being extracted from the inside. Thereby, the side wall part 5 can be folded easily.

底面部6は、天井作業用養生装置が天井1に設けられる場合に、開口部11に対向するようになっている。底面部6は、側壁部5の下端部に配置されている。底面部6は、天井作業用養生装置が天井1に設けられる場合に、側壁部5とともに開口部11を下方から塞ぐ。   The bottom surface portion 6 is configured to face the opening portion 11 when the ceiling work curing device is provided on the ceiling 1. The bottom surface portion 6 is disposed at the lower end portion of the side wall portion 5. The bottom surface portion 6 closes the opening portion 11 together with the side wall portion 5 when the ceiling work curing device is provided on the ceiling 1.

底面部6には、作業者が進入可能な貫通孔61が形成されている。これにより、天井作業用養生装置が天井1に設けられた場合に、作業者は、貫通孔61に下方から進入することによって、空調室内機2の分解作業を行うことができる。   A through hole 61 through which an operator can enter is formed in the bottom surface portion 6. Thereby, when the curing apparatus for ceiling work is provided on the ceiling 1, the operator can perform the disassembly work of the air conditioning indoor unit 2 by entering the through hole 61 from below.

次に、天井作業用養生装置を用いて空調室内機2の分解作業を行う手順について説明する。まず、作業者は、側壁部5の内部に窒素を入れて、側壁部5の形状を円筒形状とする。その後、作業者は、天井作業用養生装置を持ち上げて、フック部41をボルト3に係合させる。これにより、天井作業用養生装置が天井1に取り付けられる。その後、作業者は、貫通孔61に下方から進入して、空調室内機2の分解作業を行う。このとき、開口部11から落下した埃などの異物は、側壁部5、底面部6または作業者に付着する。これにより、開口部11から落下した異物が、床面に付着することが抑制される。   Next, the procedure for disassembling the air conditioning indoor unit 2 using the ceiling work curing device will be described. First, an operator puts nitrogen into the inside of the side wall part 5, and makes the shape of the side wall part 5 cylindrical. Thereafter, the worker lifts the ceiling work curing device and engages the hook portion 41 with the bolt 3. Thereby, the curing apparatus for ceiling work is attached to the ceiling 1. Thereafter, the worker enters the through hole 61 from below and disassembles the air conditioning indoor unit 2. At this time, foreign matter such as dust falling from the opening 11 adheres to the side wall 5, the bottom surface 6 or the operator. Thereby, it is suppressed that the foreign material which fell from the opening part 11 adheres to a floor surface.

また、作業者が水を用いて空調室内機2を洗浄する際には、空調室内機2から飛び散った水は、側壁部5および底面部6によって室内に拡散することが防止される。これにより、洗浄に用いられた水が落下する領域がより狭くなるので、落下した水を除去する作業の効率を向上させることができる。   Further, when the operator cleans the air conditioning indoor unit 2 using water, the water splashed from the air conditioning indoor unit 2 is prevented from diffusing into the room by the side wall portion 5 and the bottom surface portion 6. Thereby, since the area | region where the water used for washing | cleaning falls becomes narrower, the efficiency of the operation | work which removes the dropped water can be improved.

また、作業者は、空調室内機2の分解作業を行う際には、空調室内機2の分解作業に用いられる複数の工具を底面部6の上に載せておく。これにより、作業者は、空調室内機2の分解作業に用いられる工具を容易に持ち替えることができる。その結果、空調室内機2の分解作業の効率を向上させることができる。   Further, when disassembling the air conditioning indoor unit 2, the worker places a plurality of tools used for the disassembling operation of the air conditioning indoor unit 2 on the bottom surface portion 6. Thereby, the operator can easily change the tool used for the disassembly work of the air conditioning indoor unit 2. As a result, the efficiency of the disassembling work of the air conditioning indoor unit 2 can be improved.

以上説明したように、この発明の実施の形態1に係る天井作業用養生装置によれば、天井1に設けられ、開口部11から下方に延びた領域7を囲む側壁部5と、開口部11に対向するように側壁部5に設けられ、側壁部5とともに開口部11を下方から塞ぐ底面部6とを備え、底面部6には、作業者が進入可能な貫通孔61が形成されているので、天井1の開口部11から落下した埃などの異物は、側壁部5、底面部6または作業者に付着する。これにより、天井1の開口部11から落下した異物が床面に付着することを抑制することができる。また、空調室内機2の分解作業を行う際に作業者がビスなどの部材を誤って落下させた場合には、落下した部材が底面部6によって床面まで落下することが防止される。これにより、落下した部材を探すために必要な時間が短くなり、分解作業の効率化を図ることができる。   As described above, according to the curing apparatus for ceiling work according to the first embodiment of the present invention, the side wall portion 5 surrounding the region 7 provided on the ceiling 1 and extending downward from the opening portion 11, and the opening portion 11. And a bottom surface portion 6 that closes the opening portion 11 together with the side wall portion 5 from below, and a through-hole 61 through which an operator can enter is formed in the bottom surface portion 6. Therefore, foreign matter such as dust falling from the opening 11 of the ceiling 1 adheres to the side wall 5, the bottom 6, or the operator. Thereby, it can suppress that the foreign material which fell from the opening part 11 of the ceiling 1 adheres to a floor surface. Further, when an operator accidentally drops a member such as a screw when disassembling the air conditioning indoor unit 2, the dropped member is prevented from falling to the floor surface by the bottom surface portion 6. As a result, the time required to search for the dropped member is shortened, and the efficiency of the disassembling work can be improved.

また、側壁部5は、内部に窒素が出し入れ可能な風船から構成されており、内部に気体が出し入れされることによって高さ方向について伸縮するので、側壁部5の内部から窒素を出すことによって側壁部5の高さ方向の寸法が小さくなり、天井作業用養生装置を容易に持ち運ぶことができ、また、側壁部5の内部に窒素を入れることによって、側壁部5が高さ方向に延びて、側壁部5の形状を円筒形状に容易にすることができる。   Further, the side wall portion 5 is composed of a balloon in which nitrogen can be taken in and out, and expands and contracts in the height direction when gas is taken in and out. The dimension in the height direction of the part 5 is reduced, the ceiling work curing device can be easily carried, and by inserting nitrogen into the side wall part 5, the side wall part 5 extends in the height direction, The shape of the side wall part 5 can be easily made into a cylindrical shape.

なお、上記実施の形態1では、側壁部5の形状が円筒形状である構成について説明したが、例えば、上方から側壁部5を視た場合に楕円形または多角形となるような筒形状など、開口部11から下方に延びた領域7を囲む形状であればよい。   In the first embodiment, the configuration in which the shape of the side wall portion 5 is a cylindrical shape has been described. For example, when the side wall portion 5 is viewed from above, a cylindrical shape that becomes an ellipse or a polygon, etc. Any shape that surrounds the region 7 extending downward from the opening 11 may be used.

また、上記実施の形態1では、側壁部5に窒素が出し入れされる構成について説明したが、例えば、空気よりも軽い気体であるヘリウムが出し入れされる構成であってもよい。この場合、天井作業用養生装置に浮力が発生し、この浮力によって、天井作業用養生装置が天井1に設置される。この場合、天井作業用養生装置は、吊り部材4を備えなくてもよい。   Moreover, although the said Embodiment 1 demonstrated the structure by which nitrogen is taken in / out in the side wall part 5, the structure by which helium which is lighter than air may be taken in / out, for example. In this case, buoyancy is generated in the ceiling work curing device, and the ceiling work curing device is installed on the ceiling 1 by this buoyancy. In this case, the ceiling work curing apparatus may not include the suspension member 4.

また、上記実施の形態1では、作業対象部材として空調室内機2を例に説明したが、これに限らず、天井に設けられる作業対象部材であればよい。   In the first embodiment, the air conditioning indoor unit 2 is described as an example of the work target member. However, the work target member is not limited to this and may be a work target member provided on the ceiling.
