[Technical Field]

[0001] The present disclosure relates to a method for transporting unwanted materials at a construction site and a system for transporting unwanted materials at a construction site. [Background technology]

[0002] Traditionally, at construction sites for buildings, condominiums, etc., materials to be used at the construction site are unloaded from vehicles loaded with materials on an unloading floor (for example, the first floor), and the unloaded materials are temporarily stored on the unloading floor.The temporarily stored materials are then transported to each floor by elevators such as temporary elevators used by workers.

[0003] For example, Patent Document 1 discloses a technology in which various materials brought into a stockyard (temporary storage area) on the first floor are transported to each floor other than the first floor using a lifting weight system formed across the first to nth floors of a building and an unmanned transport vehicle.

[0004] According to the technology disclosed in Patent Document 1, various materials delivered to a construction site can be automatically transported to designated work areas and work locations without any human intervention, allowing material transportation work to be carried out outside of working hours, such as at night.

[0014] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. However, more detailed explanation than necessary, for example, detailed explanation of well-known matters or redundant explanation of substantially the same configuration, may be omitted.

[0015] The drawings described below and referenced below are provided to enable those skilled in the art to understand the present disclosure, and are not intended to limit the scope of the claims of the present disclosure.

[0016] First Embodiment 1 is a diagram illustrating an example of a material / waste material transport system according to an embodiment of the present disclosure. As shown in this figure, a temporary elevator (temporary EV) 10, which is an example of an elevator constituting the material / waste material transport system, and a temporary structure 20 are installed inside a high-rise building 1 (building) under construction, which is an example of a construction site.

[0017] Temporary elevator 10 is installed to penetrate each floor from the first basement floor to the nth floor. Temporary elevator 10 is equipped with a car 11 and is mainly used to transport workers, materials, unnecessary materials, etc. involved in the construction of high-rise building 1. Note that the waiting position of car 11 is the first floor. Temporary elevator 10 is equipped with a drive device such as a hoist, and the drive device raises and lowers temporary elevator 10 between the first basement floor and the nth floor of high-rise building 1. Note that temporary elevator 10 that is no longer needed as construction progresses is dismantled, or a permanent elevator to be used by users of high-rise building 1 is installed in the place where temporary elevator 10 was installed, using part or all of the structure related to temporary elevator 10.

[0018] Temporary structure 20 is installed to penetrate each floor from the first basement floor to the second basement floor. Temporary structure 20 is equipped with a material / unwanted material transport elevator (material / unwanted material transport EV) 21, which is an example of a material elevator. Material / unwanted material transport elevator 21 is equipped with a material / unwanted material car 22 for loading materials, unwanted materials, etc., and is mainly used to transport materials, unwanted materials, etc. related to the construction of high-rise building 1. The material / unwanted material transport elevator 21 is equipped with a drive device, such as a hoist, which raises and lowers material / unwanted material car 22 between the first basement floor and the second basement floor. After temporary structure 20, which is no longer needed, is dismantled, floors and ceilings will be installed in the area where temporary structure 20 was installed on the first and second basement floors.

[0019] Here, unnecessary materials in an embodiment of the present disclosure will be described. Unnecessary materials in an embodiment of the present disclosure refer to waste (general waste, industrial waste) and machinery, equipment, materials, etc. that are no longer needed at the site where workers are working (the floor where workers are working). Machinery, equipment, materials, etc. that are no longer needed at the site where workers are working are moved from the current site (e.g., the third floor) at the construction site to another site (e.g., the tenth floor) or removed from the construction site. Therefore, the types of unnecessary materials are classified into waste, materials needed for other floors that are not needed (not used) at the current site (e.g., the third floor) at the construction site but are needed (used) at another site (e.g., the tenth floor), and removed materials that are no longer needed at the construction site and are therefore removed from the construction site.

[0020] FIG. 2 is a diagram showing an example of the layout of each floor. FIG. 2(a) is a plan view of the first floor, which is the unloading floor where materials are unloaded from vehicles carrying them, and the loading floor where waste (unwanted materials) are loaded onto vehicles (e.g., waste-carrying vehicles) and removal materials (unwanted materials) are loaded onto vehicles (e.g., removal material-carrying vehicles). As shown in this figure, the first floor is provided with a truck yard 30 (unwanted material loading area), which is a space for unloading materials and loading of unnecessary materials. The truck yard 30 is partitioned into a work area 31 for unloading and loading, a waste loading area 32 for placing waste α to be loaded, and a removal material loading area 33 for placing removal materials β to be loaded.

[0021] In this embodiment, a total of three temporary elevators 10 are installed in the high-rise building 1, for example, temporary elevator No. 1 10a, temporary elevator No. 2 10b, and temporary elevator No. 3 10c. The number of temporary elevators 10 may be one or more. Each of the temporary elevators 10a to 10c is provided with a car door (no reference number) that opens and closes by a drive device such as a motor. Cars 11a to 11c installed in the temporary elevators 10a to 10c are on standby on the first floor.

[0022] Furthermore, the material / unwanted material basket 22 is provided with a first door 23a on the side facing the truck yard 30, and a second door 23b at a position opposite the first door 23a. The first door 23a and the second door 23b are provided with corresponding drive devices such as motors, and the first door 23a and the second door 23b are opened and closed by the respective drive devices.

[0023] FIG. 2(b) is a plan view of the first and second basement floors, which are adjacent to the first floor, the unloading floor. As shown in this figure, the first and second basement floors have a temporary material / unwanted material storage area 40, which is a space for temporarily storing materials transported by the material / unwanted material transport elevator 21 and for temporarily storing unwanted materials to be transported by the material / unwanted material transport elevator 21, located opposite the second door 23b. The temporary material / unwanted material storage area 40 is divided into a material temporary storage area 41 for temporarily storing materials, a waste temporary storage area 42 for temporarily storing waste α to be transported to the loading floor, and a removed material temporary storage area 43 for temporarily storing removed materials β to be transported to the loading floor. The waste temporary storage area 42 and the removed material temporary storage area 43 are collectively referred to as the "unwanted material temporary storage area."

[0024] Figure 2(c) is a plan view of the floors (3rd floor and above) above the adjacent unloading floor. As shown in this figure, the upper floors are provided with material storage areas 51-53, which are spaces for storing materials transported by temporary elevators 10a-10c; waste storage area 54, which is a space for storing waste α to be transported to the loading floor; removed material storage area 55, which is a space for storing removed material β to be transported to the loading floor; other-floor storage area 56, which is a space for storing other-floor required material γ (machines, equipment, materials, etc. no longer needed on the current floor) that will be used on another floor (destination floor); and required material storage area 57, which is a space for storing other-floor required material γ (machines, equipment, materials, etc. used on the current floor) transported from another floor. The waste storage area 54, removed material storage area 55, and other-floor storage area 56 are collectively referred to as the "unnecessary material storage area."

[0025] Next, a method for transporting materials and the like at a construction site according to this embodiment will be described with reference to Figures 3, 4A, and 4B. Figure 3 is a flow diagram showing a method for transporting materials and the like at a construction site (material transport process).

[0026] First, it is determined whether unloading is necessary (step S1). If unloading is necessary, the process proceeds to step S2, a temporary material storage step, whereas if unloading is not necessary, the process proceeds to step S3.

[0027] The material temporary storage process will now be described with reference to Figures 4A(a) to 4A(c). The material temporary storage process is a process in which materials loaded onto a vehicle are temporarily stored in a temporary storage area for materials and unnecessary materials. In the material temporary storage process, as shown in Figure 4A(a), the material / unwanted material car 22 of the material / unwanted material transport elevator 21 is stopped on the first floor and the first door 23a is opened. Vehicles 60a loaded with material X (materials, etc.) and vehicles 60b loaded with material Y (materials, etc.) are parked in the work area 31 of the truck yard 30 on the first floor. Next, forklifts 70a and 70b, which are examples of loading machines, unload the material X loaded onto vehicle 60a and the material Y loaded onto vehicle 60b. The materials X and Y unloaded by the forklifts 70a and 70b are held by the forklifts 70a and 70b, respectively, and loaded into the material / waste material basket 22. Note that the loading / unloading machine is not limited to a forklift, and may be any machine capable of transporting, lifting, and lowering loads. The loading / unloading machine may also be configured to automatically travel and load under the control of a control device. Furthermore, in the case of light materials, the materials may be unloaded onto a cart and carried into the material / waste material basket 22, or the materials may be carried into the material / waste material basket 22 by a person.

[0028] Next, as shown in FIG. 4A(b), when loading of materials X and Y into the cage 22 for materials and waste materials is completed, the first door 23a is closed, and the cage 22 for materials and waste materials is moved to the second floor or the first basement floor by the elevator 21 for transporting materials and waste materials, thereby transporting the materials X and Y.

[0029] Next, as shown in FIG. 4A(c), when the material / unwanted material basket 22 loaded with materials X and Y arrives at the second floor or the first basement, the second door 23b is opened. A forklift 70c, which is an example of a transport vehicle, is waiting on the second floor or the first basement. The forklift 70c removes materials X and Y from the material / unwanted material basket 22 and temporarily stores the removed materials X and Y in the temporary material storage area 41 of the temporary material / unwanted material storage area 40. Note that the transport vehicle here is not limited to a forklift, and may be the above-mentioned loading machine. Furthermore, the transport vehicle may be one that uses rails, guides, etc., and automatically travels along a route following the rails, guides, etc.

[0030] In the material temporary storage process of this embodiment, unloaded materials, etc. are preferentially temporarily stored in a material temporary storage area 41 provided on the second floor. If it becomes difficult to temporarily store materials, etc. in the material temporary storage area 41 provided on the second floor (for example, there is no temporary storage space), or if there are so many materials, etc. that need to be unloaded that simply transporting the materials, etc. to the second floor would make this process inefficient, the materials, etc. are temporarily stored in a material temporary storage area 41 provided on the first basement floor. In this case where material temporary storage areas 41 are provided on multiple floors, the priority of the multiple material temporary storage areas 41 may be determined as appropriate at the discretion of the site.

[0031] Returning to FIG. 3, in step S3, it is determined whether or not to move the materials temporarily placed in the material temporary storage area 41. If the materials are to be moved, the process proceeds to step S4, whereas if the materials are not to be moved, the process returns to step S1.

[0032] In step S4, it is determined whether the worker is working, and if the worker is working, the process returns to step S1, whereas if the worker is not working (not working), the process proceeds to the material transport process (step S5). Note that the case where the worker is not working (not working) includes any one or more of the following times outside of working hours: nighttime, holidays, and break times, and may be any time period when the worker is not using the temporary elevator 10. When the material transport process (step S5) is completed, the process proceeds to the material transport process (step S6).

[0033] Here, the material transport process will be explained using Fig. 4B(d) and (e), and the material transportation process will be explained using Fig. 4B(f).

[0034] The material transport process is a process of transporting materials, etc., temporarily stored in the temporary storage area for materials and unnecessary materials to the floor (destination floor) where these materials, etc. are used. In the material transport process, as shown in FIG. 4B(d), when materials X and Y are moved from the temporary material storage area 41 on the second floor, for example, the cars 11a and 11b of two (some) of the three (all) temporary elevators 10a to 10c are stopped at the second floor, and their car doors are opened. Next, material Y from the temporary material storage area 41 is loaded into car 11a by a forklift 70c, and material X from the temporary material storage area 41 is loaded into car 11b by a forklift 70c. Whether to use all of the temporary elevators 10a to 10c to transport the temporarily stored materials or to use one or two of all of the temporary elevators 10a to 10c can be decided at the site as appropriate.

[0035] Next, as shown in FIG. 4B(e), when loading of material Y into car 11a or loading of material X into car 11b is completed, the car doors are closed and temporary elevators 10a and 10b are used to move cars 11a and 11b to the destination floor, for example, floor 10, thereby transporting materials X and Y.

[0036] The material transport process is a process of depositing materials, etc., transported to a destination floor in a material storage area provided on the destination floor. In the material transport process, as shown in FIG. 4B(f), when car 11a carrying material Y or car 11b carrying material X arrives at the 10th floor, the respective car doors are opened. On the 10th floor, hand trucks 80a-80c, which are an example of transport vehicles, and their respective operators 90a-90c are waiting. Then, operator 90a operates hand truck 80a to transport material Y to material storage area 51 and place the transported material Y in material storage area 51. Also, operator 90b operates hand truck 80b to transport material Y to material storage area 52 and place the transported material Y in material storage area 52. Furthermore, the operator 90c operates the hand lift 80c to transport the material X to the material storage area 53 and place the transported material X in the material storage area 53. The transport vehicle here is as described above.

[0037] The material transport process (step S5) and the material transportation process (step S6) are repeatedly executed when there is still material X (Y) in the temporary material / unnecessary material storage area 40 that needs to be transported to the material storage area 51 (52, 53).

[0038] As described above, in this embodiment, a temporary storage area for materials and unwanted materials 40 is provided on an adjacent floor (the second floor or the first basement floor) adjacent to the unloading floor (the first floor), and a temporary structure 20 equipped with an elevator for transporting materials and unwanted materials 21 is installed inside a building under construction (e.g., a high-rise building 1) from the unloading floor to the adjacent floor. Materials to be used in construction are transported to the adjacent floor by the elevator for transporting materials and unwanted materials 21, allowing the materials to be temporarily stored in the temporary storage area 41 of the temporary storage area for materials and unwanted materials 40 provided on the adjacent floor. This eliminates the need for vehicle traffic and allows for the provision of a large temporary storage area on an adjacent floor where worker traffic is relatively less than on the unloading floor, thereby improving the efficiency of temporary storage of materials. Furthermore, this eliminates the need to provide a temporary storage area on the unloading floor, or allows the space for the temporary storage area on the unloading floor to be reduced so as not to interfere with construction work or the passage of people involved in the work.

[0039] Furthermore, if the elevator 21 for transporting materials and unwanted materials is not installed, the temporary elevators 10 (10a, 10b, 10c) will be used to transport materials and the like in addition to transporting workers. Therefore, in order to ensure the ability to transport materials and the like without reducing the mobility of workers, it is necessary to add another temporary elevator 10. In contrast, in this embodiment, by installing the elevator 21 for transporting materials and unwanted materials instead of one temporary elevator 10, it is possible to ensure the ability to transport materials and the like without reducing the mobility of workers.

[0040] Furthermore, since the installation range of the temporary structure 20 equipped with the elevator 21 for transporting materials and unnecessary materials is limited to the adjacent floor rather than extending to the upper floors such as the nth floor, the amount of material required to install the temporary structure 20 can be reduced. Furthermore, the time required to install the temporary structure 20 and the time required to dismantle the temporary structure 20 after it is no longer needed can be shortened. Furthermore, the installation work for the floors and ceilings after the temporary structure 20 is dismantled is limited to the unloading floor and the adjacent floor. Furthermore, the reduction in strength and rigidity caused by forming a cavity up to the upper floors such as the nth floor within the building is suppressed. Therefore, the negative impact on the construction of the building caused by extending the installation range of the temporary structure 20 for the purpose of temporarily storing materials on the adjacent floor to the upper floor such as the nth floor can be minimized, while the efficiency of the temporary storage work for materials, etc. can be improved. Therefore, when considering the entire construction of the building, the construction period and work time can be shortened.

[0041] Second Embodiment Next, a material / unwanted material transport system and a material transport process according to a second embodiment of the present disclosure will be described with reference to Fig. 5. Note that in the second embodiment, configurations different from those in the first embodiment will be described, and a description of configurations similar to those in the first embodiment will be omitted.

[0042] In the first embodiment described above, the temporary structure is set up inside a high-rise building, but the present invention is not limited to this and the temporary structure may be set up outside a high-rise building.

[0043] As shown in FIG. 5(a), a temporary structure (temporary platform) 200 is installed adjacent to a high-rise building 100 under construction, which is an example of a construction site. The temporary structure 200 is a two-story temporary structure installed at a height equivalent to the first and second floors of the high-rise building 1. The area of ​​the high-rise building 1 that overlaps with the temporary structure 200 has no exterior walls or the like installed, allowing transport vehicles and the like to pass through. The temporary structure 200 is equipped with a material / unwanted material transport elevator (material transport EV) 210, which is an example of an elevator. The material / unwanted material transport elevator 210 is equipped with a material / unwanted material car 220 for loading materials and the like. The material / unwanted material car 220 is parked on the first floor. The elevator 210 for transporting materials and unwanted materials uses a drive device to raise and lower a cage 220 for materials and unwanted materials between the first floor, which is the unloading floor, and the adjacent second floor.

[0044] FIG. 5(b) is a plan view of the first floor, which is the unloading floor where materials are unloaded from vehicles loaded with materials, etc. As shown in this figure, a truck yard 300 (unwanted material loading area), which is a space for unloading materials, etc., is provided on the first floor of the temporary structure 200. The truck yard 300 is divided into a work area 310 for unloading and loading work, a loaded waste area 320 for placing the waste α to be loaded, and a loaded and removed material area 330 for placing the removed material β to be loaded. In addition, the material / unwanted material basket 220 is provided with a door 230 that opens and closes by a drive mechanism on the side facing the truck yard 300.

[0045] Figure 5(c) is a plan image diagram of the second floor, which is adjacent to the first floor, which is the unloading floor. As shown in this figure, the temporary structure 200 has a temporary material / unwanted material storage area 400 on the second floor, which is a space for temporarily storing materials transported by the material / unwanted material transport elevator 210. The temporary material / unwanted material storage area 400 is provided in a position facing the door 230. The temporary material / unwanted material storage area 400 is partitioned into a temporary material storage area 410 for temporarily storing materials, a temporary waste storage area 420 for temporarily storing waste α to be transported to the loading floor, and a temporary removed material storage area 430 for temporarily storing removed materials β to be transported to the loading floor. The method of transporting materials etc. (material transport process) in the second embodiment is almost the same as in the first embodiment, but the difference is that the door 230 of the material / waste material basket 220 is opened and closed when loading materials into the material / waste material basket 220 on the first floor and when unloading materials from the material basket 220 on the second floor.

[0046] As described above, in this embodiment, a temporary structure 200 is installed outside a building under construction (e.g., high-rise building 100) and includes an elevator 210 for transporting materials and unwanted materials that moves up and down between the unloading floor and an adjacent floor. A truck yard 300 is provided on the unloading floor (first floor) inside temporary structure 200, and a temporary storage area 400 for materials and unwanted materials is provided on an adjacent floor (second floor) inside temporary structure 200, thereby enabling materials and the like to be unloaded and temporarily stored outside the building. Therefore, materials can be unloaded and temporarily stored outside the building, which is less susceptible to the traffic of vehicles and workers than inside the building, improving the efficiency of the work of temporarily storing materials and the like.

[0047] Furthermore, because the installation range of the temporary structure 200 equipped with the elevator 210 for transporting materials and unnecessary materials is limited to the adjacent floor rather than extending to upper floors such as the nth floor, the amount of material required to install the temporary structure 200 can be reduced, and the installation work time of the temporary structure 200 and the dismantling work time of the temporary structure 200 that is no longer needed can be shortened. Furthermore, because the temporary structure 200 is installed outside the building, construction work after the dismantling of the temporary structure 200 is also limited to areas that overlap with the temporary structure 200. This minimizes the negative impact on the construction of the building caused by the temporary structure 200 installed on an adjacent floor for the purpose of temporarily storing materials, etc., while improving the efficiency of the temporary storage work of materials, etc. Therefore, when considering the construction of the building as a whole, it is possible to shorten the construction period and work time related to the construction.

[0048] <Third embodiment> Next, a material / unwanted material transport system and a material transport process according to a third embodiment of the present disclosure will be described with reference to Figures 6 and 7(a). Note that in the third embodiment, configurations that are different from those in the first and second embodiments will be described, and descriptions of configurations that are similar to those in these embodiments will be omitted.

[0049] In the first and second embodiments described above, the temporary structure 20 is set up inside or outside the high-rise building 1. However, the present invention is not limited to this, and it is also possible not to set up a temporary structure.

[0050] As shown in Figures 6(a) and 6(c), a material entrance 1100 is provided in an area on the second floor of a high-rise building 1000 under construction, which is an example of a construction site, where exterior walls have not yet been installed. A temporary storage area for materials and unwanted materials 4000 is also provided on the second floor of the high-rise building 1000. The temporary storage area for materials and unwanted materials 4000 is partitioned into a temporary material storage area 4100 for temporarily storing materials, a temporary waste storage area 4200 for temporarily storing waste α to be transported to the loading floor, and a temporary removed material storage area 4300 for temporarily storing removed materials β to be transported to the loading floor. Furthermore, as shown in Figure 6(b), a truck yard 3000 is provided on the site outside the high-rise building 1000, corresponding to the first floor. The truck yard 3000 is divided into a work area 3100 for unloading and loading operations, a loading waste area 3200 for placing the waste α to be loaded, and a loading and removal material area 3300 for placing the removal material β to be loaded.

[0051] In the method for transporting materials, etc. (material transport process) of this embodiment, the material temporary storage process (step S2) in the above-mentioned material transport process (see Figure 3) is a different process as described below, but the other processes are the same.

[0052] 7(a) is a diagram showing the temporary material storage step in the material transportation step of this embodiment. As shown in this figure, in the temporary material storage step, a vehicle 60a loaded with material X (materials, etc.) (a vehicle 60b loaded with material Y) and the like are parked in a truck yard 3000. Next, the material X (Y) loaded on the vehicle 60a (60b) is unloaded by a telehandler 5000, which is an example of a cargo handling machine and is equipped with a telescopic boom and a pallet fork (or bucket) or the like at the tip of the boom.

[0053] Next, the unloaded material X(Y) is lifted to the second floor by the telehandler 5000 and carried in through the material entrance 1100. The material X(Y) carried in through the material entrance 1100 is transported by the forklift 70c and temporarily stored in the temporary material / unwanted material storage area 4000. Note that the handling machine is not limited to a telehandler, and any machine capable of lifting materials to an upper floor, such as a crane, may be used. It is also possible to use a handling machine that unloads materials and a lifting machine that lifts the unloaded materials to the second floor. It is also possible to use a transporting machine that is not limited to a forklift. For example, in the case of light materials, a hand lift, a dolly, or the like may be used to transport the materials. It is also possible to configure some or all of the handling machine, lifting machine, and transporting machine to automatically travel, handle, or transport the materials under the control of a control device.

[0054] As described above, in this embodiment, a truck yard 3000 is provided on a site corresponding to the first floor outside a building under construction (e.g., a high-rise building 1000). Furthermore, by providing a material entrance 1100 and a temporary storage area for materials and unwanted materials 4000 on the second floor, materials and the like are unloaded at the truck yard 3000 using a loading machine, and then the materials and the like are lift-loaded to the second floor by the loading machine. The lift-loaded materials and the like are then temporarily stored in the temporary storage area for materials and unwanted materials 4000 by a transporter. Therefore, materials can be unloaded outside the building, which is less affected by the traffic of vehicles and workers than inside the building. The unloaded materials can be temporarily stored on an adjacent floor from outside, improving the efficiency of the temporary storage of materials and the like. Furthermore, the efficiency of the temporary storage of materials and the like can be improved without installing a temporary structure 20 (200). Therefore, when considering the entire construction of a building, the construction period and work time related to the construction can be shortened.

[0055] <Fourth embodiment> Next, a material transport process according to a fourth embodiment of the present disclosure will be described with reference to Fig. 7(b). Note that in the fourth embodiment, configurations different from those of the first to third embodiments will be described, and descriptions of configurations similar to those of these embodiments will be omitted.

[0056] The material and unwanted material transport system according to the fourth embodiment differs from the material and unwanted material transport system according to the third embodiment (see FIG. 6) in that there is no material entrance 1100 on the second floor, there are temporary storage areas 4000 for materials and unwanted materials on the second floor and the first basement floor, and temporary elevators 10 (10a-10c) are used to temporarily store unloaded materials. When the temporary elevators 10 (10a-10c) are used to temporarily store materials, their use is limited (operated or controlled (set)) to floors where temporary storage areas 4000 for materials and unwanted materials are located, such as from the second floor to the first basement floor. Alternatively, one or several of the temporary elevators 10a-10c can be used for temporary storage of materials (either in combination with or exclusively for use by workers).

[0057] In the method for transporting materials, etc. (material transport process) of this embodiment, the material temporary storage process (step S2) in the above-mentioned material transport process (see Figure 3) is a different process as described below, but the other processes are the same.

[0058] 7(b) is a diagram showing a material temporary storage step in the material transportation step of this embodiment. As shown in this figure, in the material temporary storage step, a vehicle 60a loaded with material X (materials, etc.) (a vehicle 60b loaded with material Y) and the like are parked in a truck yard 3000. Next, a forklift 70a (70b), which is an example of a loading machine, unloads the material X (Y) loaded on the vehicle 60a (60b).

[0059] Next, the unloaded material X (Y) is loaded by a forklift 70a (70b) into the car 11 of a temporary elevator 10 waiting on the first floor. Then, the temporary elevator 10 moves the car 11 to the second floor, thereby transporting the material X (Y) to the second floor. The material X (Y) transported to the second floor is removed from the car 11 by a forklift 70c, transported, and temporarily stored in the temporary storage area for materials and unnecessary materials 4000. Furthermore, the temporary elevator 10 moves the car 11 to the first basement floor, thereby transporting the material X (Y) to the first basement floor. The material X (Y) transported to the first basement floor is removed from the car 11 by a forklift 70c, and temporarily stored in the temporary storage area for materials and unnecessary materials 4000. Note that the loading and unloading machines and transporting machines may be the same as those described above.

[0060] As described above, in this embodiment, a truck yard 3000 is provided on a site corresponding to the first floor outside a building under construction (e.g., a high-rise building 1000). Furthermore, temporary storage areas 4000 for materials and unwanted materials are provided on the second floor and the first basement floor. Materials are unloaded at the truck yard 3000 using a loading machine, loaded into the car 11 of the temporary elevator 10, and transported to the second floor or the first basement floor by the temporary elevator 10. The materials transported to the second floor or the first basement floor are then temporarily stored in the temporary storage area 4000 for materials and unwanted materials by a transport machine. Therefore, materials can be unloaded outside the building, which is less affected by the traffic of vehicles and workers than inside the building. Furthermore, by limiting the use range of the temporary elevator and using it for transporting unloaded materials temporarily, materials can be temporarily stored on adjacent floors. This improves the efficiency of temporary storage of materials while minimizing the impact on worker movement. Furthermore, the efficiency of temporary storage of materials and the like can be improved without setting up the temporary structure 20 (200). Therefore, when considering the entire construction of a building, it is possible to shorten the construction period and work time involved in the construction.

[0061] <Effects of the First to Fourth Embodiments> According to these embodiments, materials loaded on vehicles can be unloaded regardless of whether workers involved in the construction of a building are working. The unloaded materials can then be efficiently temporarily stored in a temporary storage area for materials and unwanted materials located on an adjacent floor adjacent to the unloading floor, which is less likely to be affected by the passage of vehicles and workers. Furthermore, since the space for the temporary storage area for materials and unwanted materials can be secured to be larger than that of the unloading floor, more materials can be brought in.

[0062] Furthermore, according to these embodiments, materials temporarily stored in the temporary storage area for materials and unnecessary materials are transported to floors higher than adjacent floors by temporary elevator 10 used by workers involved in the construction of the building outside of the workers' working hours, thereby reducing the time workers spend waiting for the temporary elevator during working hours. This also reduces the waiting time for the temporary elevator during workers' arrival and departure times or break times, and alleviates congestion caused by waiting for the temporary elevator. Furthermore, the transport of temporarily stored materials to upper floors is not affected by the workers' use of the temporary elevator, so materials can be transported to upper floors efficiently.

[0063] Furthermore, according to these embodiments, by installing the elevators 21, 210 for transporting materials and unwanted materials, the elevators 21, 210 for transporting materials and unwanted materials can be used as dedicated elevators for transporting unloaded materials, etc. to adjacent floors. Furthermore, by installing the elevators 21, 210 for transporting materials and unwanted materials, the temporary elevator 10 can be used as a dedicated or priority elevator for workers during work hours. Therefore, it is possible to improve the efficiency of transporting unloaded materials, etc. and the movement efficiency of workers.

[0064] Fifth Embodiment Next, a material / unwanted material transport system and an unnecessary material transport process according to a fifth embodiment of the present disclosure will be described with reference to Figures 8 to 11. In each of the above-described embodiments, a method for transporting materials, etc. in a material / unwanted material transport system has been described, but in the fifth embodiment, a method for transporting unnecessary materials, etc. in a material / unwanted material transport system will be described. Note that in the fifth embodiment, a description of the same configuration as in the above-described embodiments will be omitted.

[0065] FIG. 8 is a flow diagram showing a method for transporting unnecessary materials at a construction site.

[0066] First, it is determined whether there is any unnecessary material in the temporary storage area for unnecessary materials (temporary waste storage area 42, temporary storage area for removed materials 43) (step S11). If there is unnecessary material, the process proceeds to the temporary storage unnecessary material transportation process in step S12, whereas if there is no unnecessary material, the process returns to step S11.

[0067] The temporarily stored unnecessary material transport process will now be described with reference to Figure 9. The temporarily stored unnecessary material transport process is a process of transporting unnecessary materials (waste α, removed materials β) that have been temporarily stored in the unnecessary material temporary storage process (step S18) described later to a loading floor. Note that the temporarily stored unnecessary material transport process is a process that can be executed regardless of whether a worker is working or not.

[0068] In the temporary storage and unnecessary material transport process, as shown in FIG. 9(a), the material / unwanted material car 22 of the material / unwanted material transport elevator 21 is stopped on an adjacent floor (the second floor or the first basement floor) and the second door 23b is opened. Subsequently, the waste α temporarily stored in the temporary waste storage area 42 of the temporary material / unwanted material storage site 40 is picked up by a forklift 70c and loaded into the material / unwanted material car 22. Furthermore, the removed material β temporarily stored in the temporary removed material storage area 43 of the temporary material / unwanted material storage site 40 is picked up by a forklift 70c and loaded into the material / unwanted material car 22. The transport vehicle here is not limited to a forklift, and may be the above-mentioned loading and unloading machine. Furthermore, the transport vehicle may be a vehicle that uses rails, guides, or the like and automatically travels along a route following the rails, guides, or the like. Furthermore, the work of loading materials into the basket 22 for materials and unnecessary materials may be carried out by hand by a person.

[0069] Next, as shown in Figure 9(b), the waste α and the removed materials β are transported by moving the material / unwanted material car 22 to the loading floor (first floor) by the material / unwanted material transport elevator 21. Subsequently, when the material / unwanted material transport elevator 21 arrives at the first floor, the first door 23a is opened. On the first floor, forklifts 70a and 70b are waiting, and the forklift 70a holds the waste α in the basket 22 for materials and unnecessary materials, and the forklift 70b holds the material β to be removed in the basket 22 for materials and unnecessary materials. The waste α held by the forklift 70a is transported to the loading waste area 32 of the truck yard 30. The material β to be removed held by the forklift 70b is transported to the loading and removal material area 33 of the truck yard 30.

[0070] 8, in step S13, it is determined whether or not the worker is at work, and if the worker is at work, the process returns to step S11, whereas if the worker is not at work (not at work), it is determined whether or not there are any unnecessary materials in the unnecessary material storage areas (waste storage area 54, removal material storage area 55, storage area for other floors 56) (step S14). Note that the cases when the worker is not at work (not at work) include any one or more of nighttime, holidays, and break times, which are outside of working hours, and may be any time period when the worker is not using temporary elevator 10.

[0071] In step S14, if there is any unnecessary material in the unnecessary material storage area, the process proceeds to step S15, whereas if there is no unnecessary material in the unnecessary material storage area, the process returns to step S11.

[0072] In step S15, it is determined whether the unnecessary material in the unnecessary material storage area is waste α or withdrawal material β. If it is waste α or withdrawal material β, the process proceeds to step S16, whereas if it is not waste α or withdrawal material β (it is necessary material γ from another floor), the process proceeds to step S19.

[0073] In step S16, it is determined whether or not the unnecessary materials in the unnecessary material storage area are to be temporarily stored. If the unnecessary materials are not to be temporarily stored, the process proceeds to step S17, whereas if the unnecessary materials are to be temporarily stored, the process proceeds to step S18.

[0074] If the unnecessary materials are not temporarily stored in step S16, the unnecessary material transport process to the loading floor is executed in step S17. The unnecessary material transport process to the loading floor will now be described with reference to Fig. 10. The unnecessary material transport process to the loading floor is a process of transporting waste α and removed materials β from the working floor to the first floor.

[0075] As shown in Figure 10(a), if the floor in question is, for example, the fifth floor, waste α generated by work on the fifth floor has been placed by workers in a waste storage area 54 provided on the fifth floor. In addition, machines, equipment, materials, etc. used in work on the fifth floor that are no longer needed at the construction site have been placed by workers in a removed material storage area 55 provided on the fifth floor as removed material β.

[0076] When the car 11a arrives at the 5th floor by the temporary elevator 10a (EV bound for the loading floor), the car door is opened. An operator 90a operates the hand lift 80a to transport waste material α from the waste storage area 54 to the car 11a. In addition, an operator 90b operates the hand lift 80b to transport removal material β from the removal material storage area 55 to the car 11a. When loading of the waste material α and removal material β into the car 11a is complete, the car door is closed and the temporary elevator 10a moves the car 11a to the 1st floor, which is the loading floor, to transport the waste material α and removal material β.

[0077] Next, as shown in Figure 10(b), when the car 11a arrives at the first floor by the temporary elevator 10a, the car door is opened. On the first floor, forklifts 70a and 70b are waiting, with the forklift 70a holding the waste α in the car 11a and the forklift 70b holding the removal material β in the car 11a. The waste α held by the forklift 70a is transported to the loaded waste area 32 of the truck yard 30. The removal material β held by the forklift 70b is transported to the loaded removal material area 33 of the truck yard 30.

[0078] The waste α placed in the loaded waste area 32 is loaded onto a waste-carrying vehicle by forklifts 70a and 70b, and the removal material β placed in the loaded removal material area 33 is loaded onto a removal material-carrying vehicle by forklifts 70a and 70b. The handling machine used in this process and the above-mentioned temporary storage unnecessary material transport process is not limited to a forklift, and any machine capable of transporting and lifting cargo (unwanted materials) may be used. The handling machine may also be configured to automatically travel and handle cargo under the control of a control device. The unnecessary materials may also be loaded onto a cart and removed from the material / unwanted material basket 22, or may be manually removed from the material / unwanted material basket 22, and placed in the respective areas.

[0079] Returning to FIG. 8 , if unnecessary materials are temporarily stored in step S16, an unnecessary material temporary storage process is executed in step S18. The unnecessary material temporary storage process will now be described with reference to FIG. 11 . The unnecessary material temporary storage process is a process of temporarily storing waste material α and removal materials β on an adjacent floor before transporting them to a loading floor. The unnecessary material temporary storage process is executed for the waste material α in the following cases: when a large amount of waste material α (removal materials β) has been placed in the loaded waste area 32 (loaded removal material area 33) and there is no space to store the waste material α (removal materials β); when it is desired to use the truck yard 30 extensively as a work area for unloading materials, etc.; when it is desired to ensure a wide traffic flow for vehicles and workers; and so on. Furthermore, for example, when a large amount of removal materials β has been placed in the loaded removal material area 33 and there is no space to store the removal materials β in the loaded removal material area 33, the unnecessary material temporary storage process is executed for the removal materials β. In addition, for example, if waste α or removal materials β are placed in the loaded waste area 32 or the loaded removal material area 33 before the arrival of a waste-loading vehicle or removal material-loading vehicle, and this obstructs the passage of workers, etc., or other work such as unloading materials, a temporary storage process for unnecessary materials is carried out.

[0080] As shown in Figure 11(a), if the floor in question is, for example, the fifth floor, waste α generated by work on the fifth floor has been placed by workers in a waste storage area 54 provided on the fifth floor. In addition, machinery, equipment, materials, etc. used in work on the fifth floor that are no longer needed at the construction site have been placed by workers in a removed material storage area 55 provided on the fifth floor as removed material β.

[0081] When the car 11a arrives at the 5th floor by the temporary elevator 10a (EV bound for the adjacent floor), the car door is opened. An operator 90a operates the hand lift 80a to transport waste material α from the waste storage area 54 to the car 11a. In addition, an operator 90b operates the hand lift 80b to transport removal material β from the removal material storage area 55 to the car 11a. When the loading of the waste material α and removal material β into the car 11a is complete, the car door is closed, and the temporary elevator 10a is used to move the car 11a to the adjacent 2nd floor, thereby transporting the waste material α and removal material β.

[0082] Next, as shown in FIG. 11(b), when the car 11a arrives at the second floor by the temporary elevator 10a, the car door is opened. On the second floor, a forklift 70c is waiting, and the waste α and removed materials β in the car 11a are held by the forklift 70c. The waste α held by the forklift 70c is transported to the temporary waste storage area 42 in the temporary storage area for materials and unnecessary materials 40. The removed materials β held by the forklift 70c are transported to the temporary storage area for removed materials 43 in the temporary storage area for materials and unnecessary materials 40.

[0083] In addition, waste α transported to the temporary waste storage area 42 by the temporary unnecessary material storage process and removed material β transported to the temporary removed material storage area 43 are transported to the loaded waste area 32 or the loaded removed material area 33 by executing the temporary unnecessary material transportation process described above.

[0084] Returning to Figure 8, if the material is not waste α or removed material β (it is material required for another floor γ) in step S15, a process of transporting material required for another floor is executed in step S19. The process of transporting material required for another floor will now be described with reference to Figure 10. The process of transporting material required for another floor is a process of transporting material required for another floor γ, which is unnecessary material no longer needed on the current floor but is needed on another floor, from the current floor to another floor.

[0085] As shown in Figure 10(a), if the current floor is, for example, the 5th floor, machines, equipment, materials, etc. used in work on the 5th floor are unnecessary materials not needed on the 5th floor, but are needed (used) on other floors, and are placed by workers, etc. in a storage area 56 for other floors provided on the 5th floor as other-floor required materials γ. Each of the other-floor required materials γ has a display (memo, label, etc.) attached to it, showing, for example, the floor number of the destination.

[0086] When the car 11b arrives at the 5th floor by the temporary elevator 10b (EV bound for other floors), the car door is opened. The operator 90c operates the hand lift 80c to transport the material γ required for other floors from the storage area 56 for other floors to the car 11b. When the loading of the material γ required for other floors into the car 11b is complete, the car door is closed and the temporary elevator 10b is used to move the car 11b to the other floor, thereby transporting the material γ required for other floors.

[0087] 10(c), for example, if the other floor is the 10th floor, when the car 11b arrives at the 10th floor by the temporary elevator 10b, the car door is opened. On the 10th floor, an operator 90c and a hand lift 80c are waiting, and the operator 90c operates the hand lift 80c to hold the other floor necessary material γ in the car 11b and transport it to the necessary material storage area 57.

[0088] When the loading floor unnecessary material transporting step (step S17), the unnecessary material temporary storage step (step S18), or the other floor necessary material transporting step (step S19) is executed, the unnecessary material transporting step is completed.

[0089] As explained above, in this embodiment, the waste α and removal materials β on each work floor are transported to the loaded waste area 32 and the loaded removal material area 33 on the loading floor (first floor) outside of the workers' working hours. Therefore, it is possible to prevent (limit) the use of elevators used by workers and other related parties during work hours for transporting unnecessary materials, and it is possible to prevent the work efficiency of the construction site from being reduced by the work of transporting unnecessary materials.

[0090] In this embodiment, a temporary storage area for materials and unnecessary materials 40 is provided on an adjacent floor (the second floor or the first basement floor) adjacent to the loading floor (the first floor), and a temporary structure 20 equipped with an elevator for transporting materials and unnecessary materials 21 is installed inside a building under construction (e.g., a high-rise building 1) from the loading floor to the adjacent floor. The temporary storage area for materials and unnecessary materials 40 is also provided on an adjacent floor, and a temporary waste storage area 42 for temporarily storing waste α and a temporary removed material storage area 43 for temporarily storing removed materials β are provided therein. The waste α and removed materials β on each work floor can be temporarily stored in the temporary waste storage area 42 and the temporary removed material storage area 43 outside of worker work hours, and the temporarily stored waste α and removed materials β are transported to the loaded waste area 32 and the loaded removed material area 33 on the loading floor using the elevator for transporting materials 21, regardless of whether or not it is worker work hours. Therefore, even if there are circumstances that make it impossible to place the waste α or the removal materials β in the loaded waste area 32 or the loaded removal materials area 33, it is possible to place the waste α or the removal materials β in the temporary waste storage area 42 or the temporary removal materials storage area 43 on an adjacent floor outside of worker working hours. Therefore, it is possible to prevent (limit) the use of elevators used by workers and other related parties during work hours for transporting unnecessary materials, and it is possible to prevent the work efficiency of the construction site from being reduced by the transporting of unnecessary materials.

[0091] Furthermore, in this embodiment, the necessary materials γ on each work floor are transported to the necessary materials storage area 57 on the other floor (destination floor) outside of the workers' work hours. Therefore, it is possible to prevent (limit) the use of elevators used by workers and other related parties during work hours for transporting the necessary materials γ on other floors, and it is possible to prevent the work efficiency of the construction site from being reduced by the work of transporting unnecessary materials.

[0092] Sixth Embodiment Next, a material / unwanted material transport system and an unwanted material transport process according to a sixth embodiment of the present disclosure will be described with reference to Figure 5. Note that this embodiment is implemented using the configuration of the second embodiment described above. Therefore, only configurations that differ from the fifth embodiment will be described, and descriptions of configurations that are the same as those of the fifth and second embodiments will be omitted.

[0093] In the temporary storage unnecessary material transport process (step S12) in this embodiment, the waste α temporarily stored in the temporary waste storage area 420 of the material / unnecessary material transport elevator 210 and the removed material β temporarily stored in the removed material temporary storage area 430 are transported to the loading floor (first floor) by the material / unnecessary material car 220 of the material / unnecessary material transport elevator 210. Then, the waste α transported to the loading floor is transported to the loaded waste area 320 of the truck yard 300, and the removed material β is transported to the loaded removed material area 330.

[0094] In addition, in the loading floor unnecessary material transportation process (step S17), waste α transported by temporary elevator 10a is transported to the loaded waste area 320 of the truck yard 300, and removal material β transported by temporary elevator 10a is transported to the loaded removal material area 330.

[0095] In addition, in the unnecessary material temporary storage process (step S18), the waste α transported by the temporary elevator 10a is temporarily stored in the waste temporary storage area 420 of the material / unnecessary material temporary storage site 400, and the removed material β transported by the temporary elevator 10a is temporarily stored in the removed material temporary storage area 430.

[0096] As described above, in this embodiment, a temporary structure 200 is installed outside a building under construction (e.g., high-rise building 100) and includes an elevator 210 for transporting materials and unnecessary materials that moves up and down between the unloading floor and an adjacent floor. A truck yard 300 is provided on the loading floor (first floor) inside temporary structure 200, and a temporary storage area 400 for materials and unnecessary materials is provided on an adjacent floor (second floor) inside temporary structure 200, thereby enabling unnecessary materials to be temporarily stored outside the building. Therefore, even if there are circumstances that prevent waste α and removed materials β from being placed in the loading waste area 320 or the loading and removal material area 330, the waste α and removed materials β can be placed in the temporary waste storage area 420 or the temporary removal material storage area 430 on the adjacent floor outside of worker working hours. Therefore, it is possible to prevent (restrict) the use of elevators used by workers and other related parties during work hours from being used to transport unnecessary materials, thereby preventing the work efficiency at construction sites from being reduced by the transport of unnecessary materials.

[0097] Seventh Embodiment Next, a material / unwanted material transport system and an unwanted material transport process according to a seventh embodiment of the present disclosure will be described with reference to Figures 6 and 7(a). Note that this embodiment is implemented using the configuration of the third embodiment described above. Therefore, only configurations that differ from the fifth and sixth embodiments will be described, and configurations similar to those of these embodiments and the third embodiment will not be described.

[0098] In the temporary storage unnecessary material transport process (step S12) in this embodiment, waste α temporarily stored in the temporary waste storage area 4200 of the material / unnecessary material temporary storage site 4000 and removed material β temporarily stored in the removed material temporary storage area 4300 are transported using a telehandler 5000 to the loaded waste area 3200 of the truck yard 3000 on the loading floor (first floor), and removed material β is transported to the loaded removed material area 3300. Note that the waste and removed material may be loaded directly from the telehandler 5000 onto a waste-loading vehicle or a removed material-loading vehicle.

[0099] In addition, in the loading floor unnecessary material transportation process (step S17), waste α transported by temporary elevator 10a is transported to the loaded waste area 3200 of the truck yard 3000, and removal material β transported by temporary elevator 10a is transported to the loaded removal material area 3300.

[0100] In addition, in the unnecessary material temporary storage process (step S18), waste α transported by the temporary elevator 10a is temporarily stored in the waste temporary storage area 4200 of the material / unnecessary material temporary storage site 4000, and removed material β transported by the temporary elevator 10a is temporarily stored in the removed material temporary storage area 4300.

[0101] As described above, in this embodiment, truck yard 3000 is provided on a site corresponding to the first floor outside a building under construction (e.g., high-rise building 1000). Material entrance 1100 and temporary material / unwanted material storage area 4000 are provided on the second floor. Unwanted materials temporarily stored in temporary material / unwanted material storage area 4000 are then transported by a loading machine to truck yard 3000 on the loading floor (first floor). Therefore, even if circumstances prevent waste α and retrieval materials β from being placed in loading waste area 3200 or loading and retrieval material area 3300, the waste α and retrieval materials β can be placed in temporary waste storage area 4200 or retrieval material storage area 4300 on an adjacent floor outside of worker work hours. This prevents (restricts) the use of elevators used by workers and other related parties during work hours for transporting unwanted materials, thereby preventing a decrease in work efficiency at a construction site due to the transport of unwanted materials.

[0102] Eighth Embodiment Next, a material / unwanted material transport system and an unwanted material transport process according to an eighth embodiment of the present disclosure will be described with reference to FIG. 7(b). This embodiment is implemented using the configuration of the fourth embodiment described above. Therefore, only configurations that differ from the fifth to seventh embodiments will be described, and a description of configurations similar to those of these embodiments and the fourth embodiment will be omitted.

[0103] In the temporary storage unnecessary material transportation process (step S12) in this embodiment, waste α temporarily stored in the temporary waste storage area 4200 of the temporary materials / unnecessary material storage site 4000 located on an adjacent floor (second floor or first basement floor) and removed materials β temporarily stored in the temporary removed material storage area 4300 are transported using temporary elevators 10 (10a to 10c) to the loaded waste area 3200 of the truck yard 3000 on the loading floor (first floor), and removed materials β are transported to the loaded removed material area 3300.

[0104] In addition, in the unnecessary material temporary storage process (step S18), waste α transported by the temporary elevator 10a is temporarily stored in the waste temporary storage area 4200 of the materials / unnecessary material temporary storage site 4000 located on the second floor or the first basement floor, and removed material β transported by the temporary elevator 10a is temporarily stored in the removed material temporary storage area 4300.

[0105] As described above, in this embodiment, a truck yard 3000 is provided on a site corresponding to the first floor outside a building under construction (e.g., a high-rise building 1000). A temporary storage area for materials and unnecessary materials 4000 is provided on the second floor and the first basement floor. The unnecessary materials temporarily stored in the temporary storage area for materials and unnecessary materials 4000 are transported to the truck yard 3000 using a temporary elevator 10. Therefore, even if circumstances prevent the waste α and the removed materials β from being placed in the loading waste area 3200 or the loading and removal material area 3300, the waste α and the removed materials β can be placed in the temporary waste storage area 4200 or the removed material storage area 4300 on an adjacent floor outside of worker work hours. Therefore, unnecessary materials can be temporarily stored while minimizing the impact on worker movement, preventing a decrease in work efficiency at the construction site due to the transport of unnecessary materials. Furthermore, the temporary storage of unnecessary materials can be performed without installing a temporary structure 20 (200).

[0106] <Effects of the Fifth to Eighth Embodiments> According to these embodiments, the transport of unnecessary materials to the loading floor or other floors can be carried out outside of the working hours of workers involved in the construction of the building. Furthermore, unnecessary materials to be transported to the loading floor can be temporarily stored in a temporary storage area for materials and unnecessary materials located on an adjacent floor adjacent to the loading floor that is less likely to be affected by the passage of vehicles and workers. Furthermore, since it is possible to ensure a larger space for the temporary storage area for materials and unnecessary materials than the loading floor, it is possible to transport a large amount of unnecessary materials when workers are not working.

[0107] Furthermore, according to these embodiments, the unnecessary materials temporarily stored in the temporary storage area for materials and unnecessary materials are transported to the loading floor, adjacent floors, or other floors by the temporary elevator 10 used by workers involved in the construction of the building outside of the workers' working hours, thereby reducing the time workers spend waiting for the temporary elevator during working hours. This also reduces the waiting time for the temporary elevator during workers' arrival and departure times or break times, and alleviates congestion caused by waiting for the temporary elevator. Furthermore, the transport of the temporarily stored unnecessary materials to the loading floor is not affected by the workers' use of the temporary elevator, so the unnecessary materials can be transported to the loading floor efficiently.

[0108] Furthermore, according to these embodiments, by installing elevators 21, 210 for transporting materials and unnecessary materials, the temporary elevator 10 can be used exclusively or as a priority elevator for workers during work hours, thereby improving the efficiency of transporting unnecessary materials and the movement of workers.

[0109] <Modifications, etc.> The elevator 21 for transporting materials and waste materials in the first embodiment is provided with two doors (first door 23a and second door 23b), so that the first door 23a is opened to carry materials, etc. into the cage 22 for materials and waste materials, and the second door is opened to carry materials, etc. out of the cage 22 for materials and waste materials. Also, the elevator 21 for transporting materials and waste materials in the fifth embodiment is provided with two doors (first door 23a and second door 23b), so that the first door 23a is opened to carry waste materials into the cage 22 for materials and waste materials, and the second door is opened to carry waste materials out of the cage 22 for materials and waste materials. However, this is not a limitation, and only one of the first door 23a and the second door 23b may be provided.

[0110] Furthermore, in the elevator 210 for transporting materials and unwanted materials in the second and sixth embodiments, one door (door 230) is provided, and the door 230 is opened to carry unwanted materials, materials, etc. into and out of the car 22 for materials and unwanted materials. However, this is not limiting, and two doors may be provided.

[0111] Furthermore, in the elevator 21 for transporting materials and waste materials in the first and fifth embodiments, the first door 23a and the second door 23b are provided on the car 22 for materials and waste materials, and in the elevator 210 for transporting materials and waste materials in the second and sixth embodiments, the car 220 for materials and waste materials is provided with the door 230. However, this is not limiting, and the respective doors (23a, 23b, 230) may not be provided on the car 22, 220 for materials and waste materials, and the respective doors (23a, 23b, 230) may be provided on each of the stopping floors of the car 22, 220 for materials and waste materials in the elevator 21, 210 for transporting materials and waste materials.

[0112] In the first and fifth embodiments, the temporary structure 20 is set up from the first basement floor to the second basement floor. However, the present invention is not limited to this, and the temporary structure 20 may be set up from the first floor to the second floor, or from the first floor to the first basement floor.

[0113] In the second and sixth embodiments, the temporary structure 200 is set up from the first floor to the second floor. However, this is not limiting, and if there is a space such as a site outside the high-rise building 100 that corresponds to the first basement floor, the temporary structure 200 may be set up from the first floor to the first basement floor, or from the second floor to the first basement floor. In this way, the first basement floor can be used as a temporary storage area 400 for materials and unnecessary materials.

[0114] In the first and fifth embodiments, the temporary storage area 40 for materials and unnecessary materials is provided on a floor (e.g., the second floor or the first basement floor) adjacent to the unloading or loading floor (e.g., the first floor), and in the second embodiment, the temporary storage area 400 for materials and unnecessary materials is provided on a floor (e.g., the second floor) adjacent to the unloading or loading floor (e.g., the first floor). Therefore, the temporary structure 20 (200) is installed across the unloading floor (loading floor) and the adjacent floor. However, this is not limiting, and the temporary storage area 40 for materials and unnecessary materials may be provided on a floor (e.g., the second floor) adjacent to the unloading or loading floor (e.g., the first floor) or on an upper floor or higher (e.g., the third floor or higher) adjacent to the adjacent floor. Furthermore, the temporary storage area 40 for materials and unnecessary materials may be provided on a floor (e.g., the first basement floor) adjacent to the unloading or loading floor (e.g., the first floor) or on a lower floor or lower (e.g., the second basement floor or lower) adjacent to the adjacent floor. In such a case, the temporary structure 20 (200) may be set up on the unloading floor (loading floor), the adjacent floor, and on floors above or below the adjacent floor. In such a case, taking into consideration the effort and time involved in setting up and dismantling the temporary structure 20 (200) and the construction work after dismantling the temporary structure 20 (200), it is preferable that the floors on which the temporary storage area 40 (400) for materials and unnecessary materials is set up be limited to the floors excluding the upper floors of the building.

[0115] In the third and seventh embodiments, the temporary storage area 4000 for materials and unnecessary materials is provided on a floor (e.g., the second floor) adjacent to the unloading floor or loading floor (e.g., the first floor). However, this is not limiting, and the temporary storage area 4000 for materials and unnecessary materials may be provided on a floor (e.g., the second floor) adjacent to the unloading floor or loading floor (e.g., the first floor) or on an upper floor or higher (e.g., the third floor or higher) adjacent to the adjacent floor. In this case, the floor on which the temporary storage area 4000 for materials and unnecessary materials is provided may be determined appropriately depending on the construction site, taking into consideration which loading machine (lifting machine) will be used, how much temporary storage space needs to be secured, and so on. Furthermore, the temporary storage area 4000 for materials and unnecessary materials and the material entrance 1100 may be provided on a floor (e.g., the first basement floor) adjacent to the unloading floor or loading floor (e.g., the first floor). In this case, for example, it is conceivable that unloaded materials, etc., can be lowered from the first floor to the first basement floor using a lifting machine or the like and carried in, and unnecessary materials can be transported from the first basement floor to the first floor using a lifting machine or the like. Alternatively, a temporary storage area for materials and unnecessary materials 4000 and a material entrance 1100 can be provided on a lower floor or higher (for example, the second basement floor or higher) adjacent to the adjacent floor (the first basement floor), and unloaded materials, etc., can be lowered from the first floor to the second basement floor using a lifting machine or the like and carried in, and unnecessary materials can be transported from the second basement floor to the first floor using a lifting machine or the like.

[0116] In the fourth and eighth embodiments, the temporary storage area for materials and unwanted materials 4000 is provided on a floor (e.g., the second floor or the first basement floor) adjacent to the unloading floor or loading floor (e.g., the first floor). However, the present invention is not limited to this. The temporary storage area for materials and unwanted materials 4000 may be provided on a floor (e.g., the second floor) adjacent to the unloading floor or loading floor (e.g., the first floor) or on an upper floor or higher (e.g., the third floor or higher) adjacent to the adjacent floor, or on a floor (e.g., the first basement floor) adjacent to the unloading floor or loading floor (e.g., the first floor) or on a lower floor or lower (e.g., the second basement floor or lower) adjacent to the adjacent floor. In this case, the floor on which the temporary storage area for materials and unwanted materials 4000 is provided may be determined appropriately depending on the work environment of the construction site, taking into consideration the degree of impact on the movement of workers.

[0117] Furthermore, the material temporary storage process in the material transportation process of the third embodiment (see FIG. 7(a)) and the material temporary storage process in the fourth embodiment (see FIG. 7(a)) may be used together. In other words, both a method of carrying unloaded materials through the material entrance 1100 using a loading machine or the like and a method of carrying them in using the temporary elevator 10 may be employed to temporarily store the materials in the temporary storage area 4000 for materials and unnecessary materials on each floor. In this case, it is possible to adopt either one or both methods for carrying the materials in, taking into consideration the size, weight, and labor (time) required for carrying them in, or to adopt either one or both methods for carrying them in, taking into consideration the use of the temporary elevator by workers during work hours. This improves the efficiency of the material temporary storage process, thereby improving the efficiency of the material transportation process as a whole.

[0118] In the first to fourth embodiments, the unloading floor is the first floor. However, this is not limiting, and the unloading floor may be the second floor or higher of the building, or a floor below the first basement floor. In the first and second embodiments, for example, if the unloading floor is the second floor of the building, the temporary structure 20 (200) is installed across the second floor and its adjacent floors, and, for example, if the unloading floor is the first basement floor of the building, the temporary structure 20 (200) is installed across the first basement floor and its adjacent floors.

[0119] Furthermore, in the fifth to eighth embodiments, the loading floor is the first floor. However, this is not limiting, and the loading floor may be the second floor or higher of a building, or a floor below the first basement floor. In the fifth and fifth embodiments, for example, if the loading floor is the second floor of a building, the temporary structure 20 (200) is installed across the second floor and its adjacent floors, and, for example, if the loading floor is the first basement floor of a building, the temporary structure 20 (200) is installed across the first basement floor and its adjacent floors.

[0120] Furthermore, in the second and sixth embodiments, the temporary structure 200 is provided with an elevator (elevator 210 for transporting materials and unnecessary materials). However, this is not limiting, and the temporary structure 200 may not be provided with an elevator. In such a case, materials and the like may be lifted by construction machinery such as a crane, a telehandler, or a large forklift, and then lifted from the unloading floor (loading floor) to an adjacent floor or a floor higher than the adjacent floor, and then transported to the temporary storage area for materials and unnecessary materials 400 provided on the adjacent floor or a floor higher than the adjacent floor. In this way, it is possible to reduce the amount of material required to set up the temporary structure 200 and shorten the time required to set up and dismantle the temporary structure 200.

[0121] Furthermore, in the second and sixth embodiments, the temporary structure 200 is provided with the temporary storage area 400 for materials and unnecessary materials. However, this is not limiting, and the temporary structure 200 may not be provided with the temporary storage area 400 for materials and unnecessary materials, and a space for the storage area 400 may be provided within the building as in the first embodiment. By doing so, it is possible to reduce the amount of materials required to set up the temporary structure 200 and shorten the time required to set up and dismantle the temporary structure 200.

[0122] Furthermore, in the material transporting process (step S5) in the first and second embodiments, temporary elevator 10 is used as an elevator. However, this is not limiting, and for example, after the temporary elevator has been dismantled, if elevators such as permanent elevators to be used by users of high-rise building 1 and luggage transport elevators to be used by these users to transport luggage have already been installed (workers use these permanent elevators, etc.), these permanent elevators, etc. may be used in the material transporting process (step S5).

[0123] In the fifth and sixth embodiments, the temporary elevator 10 is used as an elevator in the loading floor unnecessary material transport step (step S17), the unnecessary material temporary storage step (step S18), and the other floor necessary material transport step (step S19). However, this is not limiting, and for example, after the temporary elevator has been dismantled, if elevators such as permanent elevators to be used by users of the high-rise building 1 and luggage transport elevators to be used by these users to transport luggage have already been installed (workers use these permanent elevators), these permanent elevators may be used in these steps.

[0124] Furthermore, processes that can be performed outside the working hours of workers in the material transport process and the unnecessary material transport process may be executed simultaneously. Also, processes that can be performed during the working hours of workers in the material transport process and the unnecessary material transport process may be executed simultaneously. In this case, for example, it is conceivable to use one of the temporary elevators 10 for transporting materials and the like, and the other temporary elevator for transporting unnecessary materials. It is also conceivable to share the material / unnecessary material transport elevators 21, 210 for transporting materials and unnecessary materials.

[0125] <Additional Notes> Other inventions according to embodiments of the present disclosure will be described below.

[0126] Conventionally, at construction sites of buildings, condominiums, and the like, materials to be used at the construction site are unloaded from vehicles loaded with the materials on a loading floor (e.g., the first floor), and the unloaded materials are temporarily stored on the loading floor, and the temporarily stored materials are transported to each floor by elevators such as temporary elevators used by workers. As an example of the background art, Japanese Patent Laid-Open Publication No. 4-75994 (Patent Document 1) discloses a technology for transporting various materials delivered to a stockyard (temporary storage area) on the first floor to each floor other than the first floor using lifting weights installed across the first to nth floors of a building and automated guided vehicles. The technology disclosed in Patent Document 1 enables various materials delivered to a construction site to be automatically transported to designated work areas and work locations without human intervention, allowing material transportation work to be carried out outside of working hours, such as at night.

[0127] However, on unloading floors, it is necessary to secure storage areas for materials to be used on those floors and traffic routes for trucks and other vehicles. Furthermore, construction work may also be carried out on unloading floors, and construction workers may pass through them. For this reason, it is difficult to secure a large temporary storage area on unloading floors. Therefore, the limited space in the temporary storage area limits the amount of materials that can be temporarily stored, and the limited amount of materials that can be temporarily stored also limits the amount of materials that can be transported to floors other than the delivery floor, making the logistics of materials used on construction sites inefficient. These are the challenges that existed.

[0128] In order to solve this problem, the following invention is described in the embodiments of the present disclosure with the aim of providing technology for streamlining the logistics of materials and the like used at construction sites.

[0132] Invention A4 is a material transportation system at a construction site according to Invention A3, characterized in that the temporary structure is set up inside the building.

[0138] In a building under construction, a temporary structure is provided from a floor where materials are unloaded and unnecessary materials are loaded to an adjacent floor adjacent to said floor, and an elevator is provided from said floor to said adjacent floor and to a floor above said adjacent floor and can be used by workers working on each floor, said temporary structure is provided with an elevator for materials and unnecessary materials provided from said floor to said adjacent floor, and said elevator for materials and unnecessary materials is used to transport said materials to said adjacent floor, and said materials transported to said adjacent floor are transported to a destination floor by said elevator, thereby Invention B4 of a material / unwanted material transport system for a construction site, characterized in that the unloaded materials are temporarily stored in a temporary storage area on the adjacent floor regardless of whether the worker is working or not, the temporarily stored materials are transported to a material storage area on the destination floor while the worker is not working, the unnecessary materials are transported to the adjacent floor by the elevator while the worker is not working, the transported unnecessary materials are temporarily stored in the temporary unnecessary material storage area on the adjacent floor, and the temporarily stored unnecessary materials are transported to an unnecessary material loading area on the loading floor regardless of whether the worker is working or not.
