Summary of the Invention

Problems to be Solved by the Invention

[0003] However, in recent years, with the problems of an aging workforce and a shortage of workers (especially a shortage of the younger generation), inexperienced workers, and an increase in foreign workers at the work site, there have been risks such as dangers in terms of safety due to lack of experience, variations in quality, and an increase in working hours due to an increase in the number of work processes.

[0004] For example, since equipment, piping around the equipment, and ducts (chambers) are separately delivered, the number of times of carrying in is large. Since the equipment, piping around the equipment, and ducts (chambers) are each attached, the number of work processes is large. The amount of work at heights increases, and the risk of accidents and the like increases. The construction quality varies depending on the experience of each worker. Since the construction contractors are different for each process, it is necessary to secure workers.

[0005] Therefore, attempts have been made to pre-integrate equipment, piping around the equipment, ducts, etc. using frame members and carry them into the site and suspend them, but there are problems such as an extra cost for the frame members.

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

Mode for Carrying Out the Invention

[0017] Embodiments of the present invention will be described in detail with reference to the drawings.

[0018] Figures 1 to 14 are front views etc. showing the pallet according to the embodiment of the present invention. Here, the pallet 1 is provided with a pipe etc. holding member 7.

[0019] The pallet 1 includes a substantially U-shaped outer frame 1a and a middle frame 1b that connects the opposing frames. Further, an adjuster 8 is attached to the middle frame 1b.

[0020] This adjuster 8 is, for example, an adjusting bolt, and its protruding amount is adjustable. A square flat plate 8a is fixed to the upper end thereof. Further, 9 is a caster, which is used when moving the pallet 1.

[0021] The pipe and other holding members 7 have a portal frame 7a erected on the upper part near the edge of the pallet 1 and a holding member 7b suspended from the upper side frame 7a1 of the portal frame 7a. Note that 7a2 are the left and right leg sides of the portal frame 7a. This holding member 7b holds pipes and the like. 7c is a drain hose pipe support member.

[0022] The whole or a part of this pipe and other holding members 7 is detachably attached 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 connecting part with the upper side frame 7a1 is detachable.

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

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

[0025] Here, the device 2 is an air conditioner, ducts 3b are attached to both sides thereof, and 3a are pipes and the like of the air conditioner 2.

[0026] In this placement step, further, the pipes 3a of the placed device 2 are connected to the pipe and other holding members 7 of the pallet 1. That is, the pipes 3a are passed through the holding member 7b of the pipe and other holding members 7 for connection.

[0027] Furthermore, with respect to the space between the pallet 1 and the equipment 2 placed thereon or the parts 3 attached to the equipment 2, the protruding amount of the adjuster 8 is adjusted, the flat plate 8a is brought into contact, and the spacer function is exerted. By adjusting the adjuster 8, when moving, the equipment 2 etc. are stably placed on the pallet 1. Also, deflection of the equipment 2 etc. can be prevented.

[0028] The pallet 1 on which the equipment etc. are placed in this way is moved to the site. At that time, since the casters 9 are attached to the lower surface of the pallet 1, the trouble of preparing a separate cart and loading it can be saved.

[0029] <Ascending step> As shown in Fig. 36, the pallet 1 on which the equipment 2 and the parts 3 attached to the equipment 2 are placed is placed on the lifting equipment 4, and the pallet 1 on which the equipment 2 and the parts 3 attached to the equipment 2 are placed is lifted up to near the ceiling by the lifting equipment 4. Here, 5 is the ceiling and 6 is the suspension bolt.

[0030] Also, with respect to the space between the pallet 1 and the lifting equipment 4 on which the pallet 1 is placed, the protruding amount of the adjuster 8 is adjusted, the flat plate 8a is brought into contact, and the spacer function is exerted. By adjusting the adjuster 8, when ascending, the pallet 1 is stably placed on the lifting equipment 4. Also, deflection of the pallet 1 can be prevented.

[0031] <Connecting step> The equipment 2 is connected to the suspension bolt 6 fixed to the ceiling 5. Further, the upper side frame 7a1 of the pipe etc. holding member 7 is also connected to the suspension bolt 6.

[0032] After that, the upper ends of both leg sides 7a2 of the pipe etc. holding member 7 are separated from the upper side frame 7a1. Both leg sides 7a2 remain fixed to the pallet 1 side. Here, the pallet 1 is in a state where it is not suspended directly or indirectly by the suspension bolt 6. <Descending step> Thereafter, as shown in Fig. 37, the pallet 1 is lowered by the lifting device 4. As a result, both leg sides 7a2 of the pallet 1 and the pipe and other holding member 7 are lowered to the ground, while on the other hand, the device 2, the parts 3 attached to the device 2, and the upper side frame 7a1 of the pipe and other 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. Moreover, since the frame of the pallet 1 does not remain on the ceiling side, there is also the advantage that the weight is reduced accordingly.

[0034] Furthermore, a seismic reinforcement 11 is attached, and as shown in Fig. 38, the duct 3b of the pipe and other holding member 7 is also suspended by the suspension bolts 6. Note that in the connection step, the attachment of the reinforcement 11 and the suspension of the duct 3b may also be performed.

[0035] In the above embodiment, when separating the pipe and other holding member 7 from the pallet 1, the upper ends of both leg sides 7a2 of the portal frame 7a of the pipe and other holding member 7 are separated from the upper side frame 7a1. However, this is not the only way, and the lower ends of both leg sides 7a2 may be separated from the pallet 1. In this case, the device 2, the parts 3 attached to the device, and the entire pipe and other holding member 7 remain on the ceiling side, and only the pallet 1 descends to the ground.

[0036] Next, the case of stacking and transporting will be described.

[0037] Figs. 29 to 34 show the case of transporting two sets of the device 2 and the parts 3 attached to the device 2 simultaneously.

[0038] Here, 10 indicates the 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 device 2 and the parts 3 attached to the device 2 are placed thereon. Thereafter, the stacking support frames 10 are erected, and on them, another pallet 1 as shown in Fig. 35 without casters 9 is attached. Note that 11 is a lashing belt wound to strongly connect the upper and lower pallets 1, 1.

[0039] Furthermore, place the second device 2 and the components 3 attached to the device 2 on the pallet 1 without the casters 9.

[0040] In this way, two sets can be transported to the site simultaneously. After that, separate the upper pallet 1 from the stacking support frame 10 and place it on the lifting device 4.

[0041] After that, as described above, after suspending this device 2 etc. from the ceiling, recover the pallet 1. Also, the device 2 etc. in the lower stage can be similarly suspended from the ceiling.
