[0001] The present invention relates to a method for suspending an air conditioner or the like from a ceiling. [Background technology]

[0002] Conventionally, the work of suspending an air conditioner from a ceiling involves preparing the air conditioner for installation, attaching the equipment suspension bolts to the ceiling, then carrying the air conditioner in, suspending the air conditioner from the suspension bolts using a lifting device, and attaching earthquake-resistant reinforcement to the suspension bolts. Next, a duct is attached to the air conditioner, the connection between the air conditioner and the duct is insulated, and suspension bolts are installed to prevent the duct from falling off. Summary of the Invention [Problem to be solved by the invention]

[0003] However, in recent years, there have been issues with aging workers on-site, labor shortages (especially among young people), and an increase in inexperienced and foreign workers. In the past, there were risks such as safety hazards due to lack of experience, variations in quality, and increased working hours due to an increase in work processes.

[0004] For example, the equipment, piping around the equipment, and ducts (chambers) are delivered separately, so there are many transports. There are many work processes because the equipment, piping around the equipment, and ducts (chambers) must be installed separately. There is an increase in the amount of work at height, which increases the risk of accidents. There is variation in construction quality depending on the experience of each worker. There is a need to secure workers because different construction companies are used for each process.

[0005] To address this issue, attempts have been made to integrate the equipment and surrounding piping and ducts using frame components beforehand, then transport and hang them at the site, but this has posed problems, such as the additional cost of the frame components.

[0006] An object of the present invention is to provide a pallet and a method for using the pallet that can simplify the work of suspending such equipment from a ceiling and reduce costs. [Means for solving the problem]

[0007] The first aspect of the present invention is a placing step of placing the integrated equipment and parts (e.g., ducts, piping, etc.) attached to the equipment to be suspended on the pallet; a lifting step in which a pallet carrying the equipment and parts incidental to the equipment is placed on a lifting device, and the pallet carrying the equipment and parts incidental to the equipment is lifted to near the ceiling by the lifting device; a connecting step of connecting at least the equipment and components associated with the equipment to a suspension bolt fixed to the ceiling; The method for using a pallet is characterized by comprising a lowering step for lowering the pallet by the lifting device.

[0017] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail with reference to the drawings.

[0018] 1 to 14 are front views showing a pallet according to an embodiment of the present invention. Here, the pallet 1 is provided with a member 7 for holding pipes and the like.

[0019] The pallet 1 has an outer frame 1a that is roughly U-shaped and an inner frame 1b that connects the opposing frames. Furthermore, an adjuster 8 is attached to the inner frame 1b.

[0020] The adjuster 8 is, for example, an adjuster bolt, and its protrusion amount is adjustable. A rectangular flat plate 8a is fixed to the upper end of the adjuster 8. Reference numeral 9 denotes a caster, which is used when moving the pallet 1.

[0021] The pipe holding member 7 has a gate-shaped frame 7a erected on the edge of the pallet 1 and holding members 7b suspended from the upper frame 7a1 of the gate-shaped frame 7a. 7a2 denotes the left and right leg sides of the gate-shaped frame 7a. The holding members 7b hold the pipes, etc. 7c is a drain hose pipe support member.

[0022] The pipe holding member 7 is attached in whole or in part to be freely detachable to the pallet 1. That is, when the whole is detachable, the lower ends of both leg sides 7a2, 7a2 are detachable from the pallet 1. When a part is detachable, the lower ends of both leg sides 7a2, 7a2 remain fixed to the pallet 1, and the upper ends of both leg sides 7a2, 7a2 are detachable, that is, the connection part with the upper side frame 7a1 is detachable.

[0023] Next, a method for using the pallet according to the embodiment of the present invention will be described.

[0024] <Placement step> As shown in FIGS. 15 to 28, the integrated device 2 and the parts 3 attached to the device 2, which are to be suspended, are placed on the pallet 1 described above.

[0025] Here, the equipment 2 is an air conditioning equipment, and ducts 3b are attached to both sides of it, and 3a is the piping of the air conditioning equipment 2, etc.

[0026] In this placing step, the piping 3a of the placed device 2 is further connected to the piping holding member 7 of the pallet 1. That is, the piping 3a is passed through and connected to the holding member 7b of the piping holding member 7.

[0027] Furthermore, the protrusion amount of the adjuster 8 is adjusted to fit the space between the pallet 1 and the equipment 2 or the parts 3 attached to the equipment 2, and the flat plate 8a comes into contact with it, thereby fulfilling the spacer function. By adjusting this adjuster 8, the equipment 2 etc. can be stably placed on the pallet 1 when moved. It is also possible to prevent the equipment 2 etc. from bending.

[0028] In this way, the pallet 1 loaded with the equipment is moved to the site. At this time, since the casters 9 are attached to the underside of the pallet 1, the trouble of preparing a separate dolly for loading the pallet can be eliminated.

[0029] <Upward step> As shown in Figure 36, a pallet 1 carrying equipment 2 and parts 3 incidental to the equipment 2 is placed on a lifting device 4, and the pallet 1 carrying equipment 2 and parts 3 incidental to the equipment 2 is raised to near the ceiling by the lifting device 4. Here, 5 is the ceiling and 6 is a hanging bolt.

[0030] Furthermore, the amount of protrusion of the adjuster 8 is adjusted to fit the space between the pallet 1 and the elevating device 4 on which it is placed, and the flat plate 8a comes into contact with it, thereby fulfilling its spacer function. By adjusting the adjuster 8, the pallet 1 is stably placed on the elevating device 4 during lifting. It is also possible to prevent the pallet 1 from bending.

[0031] <Consolidation step> The device 2 is connected to the suspension bolts 6 fixed to the ceiling 5. Furthermore, the upper frame 7a1 of the pipe holding member 7 is also connected to the suspension bolts 6.

[0032] Thereafter, the upper ends of both leg sides 7a2 of the pipe holding member 7 are separated from the upper side frame 7a1. Both leg sides 7a2 remain fixed to the pallet 1. At this point, the pallet 1 is not suspended from the suspension bolts 6 either directly or indirectly. <Descent step> 37, the pallet 1 is lowered by the lifting device 4. As a result, the pallet 1 and both leg sides 7a2 of the pipe etc. holding member 7 are lowered to the ground, while the equipment 2, parts 3 attached to the equipment 2, and the upper side frame 7a1 of the pipe etc. holding member 7 remain on the ceiling 5 side.

[0033] In this way, the pallet 1 lowered to the ground can be reused, which helps reduce material costs, and also has the advantage of reducing the weight because the frame of the pallet 1 does not remain on the ceiling side.

[0034] Furthermore, earthquake-resistant reinforcement material 11 is attached, and as shown in Figure 38, duct 3b of pipe holding member 7 is also suspended by suspension bolts 6. Note that, in the connecting step, the attachment of reinforcement material 11 and suspension of duct 3b may also be performed.

[0035] In the above embodiment, when the pipe holding member 7 is separated from the pallet 1, the upper ends of both leg sides 7a2 of the gate-shaped frame 7a of the pipe holding member 7 are separated from the upper side frame 7a1, but this is not limiting, and the lower ends of both leg sides 7a2 may be separated from the pallet 1. In this case, the equipment 2, parts 3 attached to the equipment, and the entire pipe holding member 7 remain on the ceiling side, and only the pallet 1 is lowered to the ground.

[0036] Next, the case of transporting the containers stacked will be described.

[0037] 29 to 34 show cases where two sets of equipment 2 and parts 3 attached to the equipment 2 are transported at the same time.

[0038] Here, 10 denotes stacking support frames erected at the four corners of the pallet 1. First, the pallet 1 with casters 9 is placed on the ground, and the integrated equipment 2 and parts 3 attached to the equipment 2 are placed on top of it. After that, the stacking support frame 10 is erected, and another pallet 1 without casters 9 as shown in Figure 35 is attached on top of it. Note that 11 denotes lashing belts wrapped around the upper and lower pallets 1, 1 to firmly connect them together.

[0039] Furthermore, a second device 2 and a part 3 attached to the device 2 are placed on the pallet 1 without casters 9.

[0040] In this way, two sets can be transported to the site at the same time. After that, the upper pallet 1 is separated from the stacking support frame 10 and placed on the lifting device 4.

[0041] After that, as described above, this device 2 and the like are hung from the ceiling, and then the pallet 1 is collected. In addition, the lower device 2 and the like can be hung from the ceiling in the same way. [Explanation of symbols]
