Description

Technical Field

[0001] The present disclosure relates to a method for transporting materials at a construction site and a material transportation system at a construction site.

Background Art

[0002] Conventionally, at a construction site of a building or a condominium, etc., unloading of materials, etc. loaded on a vehicle is performed at an unloading floor (for example, the first floor) where the materials are unloaded, and the unloaded materials, etc. are temporarily placed on the unloading floor. Also, the temporarily placed materials, etc. are transported to each floor by an elevator such as a temporary elevator used by workers.

[0003] For example, Patent Document 1 discloses a technique in which a heavy lift formed from the first floor to the nth floor of a building and an automated guided vehicle transport various materials carried into a stockyard (temporary storage place) on the first floor to floors other than the first floor.

[0004] According to the technique disclosed in this Patent Document 1, since various materials carried into the construction site can be automatically and unmannedly transported to a designated work area and work position, the material transportation work can be performed outside working hours such as at night.

Summary of the Invention

Problems to be Solved by the Invention

[0006] However, at the unloading floor, it is necessary to secure a place for placing materials, etc. used on that floor and a traffic line for vehicles such as trucks to pass through. Also, construction work may be performed or work-related personnel may pass through at the unloading floor. Therefore, it is difficult to secure a wide temporary storage place at the unloading floor.

[0007] Therefore, since the space of the temporary storage area is limited, the amount of materials and the like that can be temporarily stored is limited, and since the amount of materials and the like that can be temporarily stored is limited, the amount of materials and the like that can be transported to floors other than the unloading floor is also limited. Thus, the logistics of materials and the like used at the construction site is inefficient.

[0008] An object of the present disclosure is to provide a technique for improving the efficiency of the logistics of materials and the like used at a construction site.

Means for Solving the Problems

[0009] In order to solve the above problems, a method for transporting materials at a construction site according to the present disclosure includes, in a building under construction, from an unloading floor where unloading of materials is performed, an adjacent floor adjacent to the unloading floor, and an elevator provided over floors above the adjacent floor and available for workers working on each floor. Regardless of whether the worker is working or not, a material temporary storage step of temporarily storing the unloaded materials in a temporary storage area on the adjacent floor; a material transportation step of transporting the temporarily stored materials to a target floor by the elevator during non-working hours of the worker; and a material transportation step of unloading the materials from the elevator at the target floor and transporting the unloaded materials to a material storage area on the target floor.

[0010] Further, a material transportation system according to the present disclosure includes a temporary structure provided from an unloading floor where unloading of materials is performed to an adjacent floor adjacent to the unloading floor, and an elevator provided from the unloading floor to the adjacent floor and over floors above the adjacent floor and available for workers working on each floor. The temporary structure is provided with a material elevator provided from the unloading floor to the adjacent floor. By transporting the materials to the adjacent floor by the material elevator and then transporting the materials transported to the adjacent floor to the target floor by the elevator, regardless of whether the worker is working or not, the unloaded materials can be temporarily stored in a temporary storage area on the adjacent floor, and during non-working hours of the worker, the temporarily stored materials can be transported to a material storage area on the target floor. [Effect of the Invention]

[0011] According to the present disclosure, it is possible to provide a technology for streamlining the logistics of materials and the like used at a construction site. [Brief Description of the Drawings]

[0013] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. However, a more detailed description than necessary, for example, a detailed description of well-known matters or a redundant description of substantially the same configuration may be omitted.

[0014] The drawings described and referred to below are provided for 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.

[0015] <First Embodiment> FIG. 1 is a diagram showing an example of a material transportation system according to an embodiment of the present disclosure. As shown in this figure, inside a high-rise building 1 (building) under construction, which is an example of a construction site, a temporary elevator (temporary EV) 10, which is an example of an elevator constituting the material transportation system, and a temporary structure 20 are installed.

[0016] The temporary elevator 10 is installed so as to penetrate each floor from the basement floor 1 to the nth floor. The temporary elevator 10 is provided with a car 11 and is mainly used for transporting workers, materials, etc. related to the construction of the high-rise building 1. Note that the standby position of the car 11 is the first floor. The temporary elevator 10 is provided with a driving device such as a hoisting machine, for example, and is raised and lowered between the basement floor 1 and the nth floor of the high-rise building 1 by the driving device. Note that the temporary elevator 10 that has become unnecessary due to the progress of construction is disassembled, or a permanent elevator used by the users of the high-rise building 1 is installed at the location where the temporary elevator 10 was installed, using part or all of the structure related to the temporary elevator 10.

[0017] The temporary structure 20 is installed so as to penetrate each floor from the basement floor 1 to the second floor. The temporary structure 20 is provided with a material transportation elevator (material transportation EV) 21, which is an example of a material elevator. The material transportation elevator 21 is provided with a material car 22 for loading materials and the like, and is mainly used for transporting materials and the like related to the construction of the high-rise building 1. Note that the standby position of the material car 22 is the first floor. The material transportation elevator 21 is provided with a driving device such as a hoisting machine, for example, and raises and lowers the material car 22 between the basement floor 1 and the second floor by the driving device. Note that after the temporary structure 20 that has become unnecessary is disassembled, the floor and ceiling of the area where the temporary structure 20 was installed from the basement floor 1 to the second floor are installed.

[0018] Figure 2 is a diagram showing an example of the layout of each floor. Fig. 2(a) is a plan image view of the first floor, which is the unloading floor where the unloading work of materials is carried out from the vehicle loaded with materials. As shown in this figure, on the first floor, there is an unloading yard 30, which is a space for carrying out the unloading work of materials. In this embodiment, in the high-rise building 1, as a temporary elevator 10, for example, a total of three units, namely a temporary elevator No. 1 10a, a temporary elevator No. 2 10b, and a temporary elevator No. 3 10c, are installed. Note that the number of the temporary elevators 10 may be one or more. In addition, each of the temporary elevators 10a to 10c is provided with a cage door (not numbered) that opens and closes by a driving device such as a motor. And the cages 11a to 11c provided in each of the temporary elevators 10a to 10c are waiting on the first floor.

[0019] In addition, the material cage 22 is provided with a first door 23a on the side facing the unloading yard, and a second door 23b is provided at the position opposite to the first door 23a. The first door 23a and the second door 23b are respectively provided with driving devices such as motors, and the first door 23a and the second door 23b are opened and closed by their respective driving devices.

[0020] Fig. 2(b) is a plan image view of the basement first floor and the second floor, which are adjacent floors adjacent to the first floor, which is the unloading floor. As shown in this figure, on the basement first floor and the second floor, a material temporary storage place 40, which is a space for temporarily placing the materials transported by the material elevator 21, is provided at a position facing the second door 23b.

[0021] Fig. 2(c) is a plan image view of the floors above (the third floor and above) the adjacent floors of the unloading floor. As shown in this figure, on the upper floors, there are provided material storage places 51 to 53, which are spaces for placing the materials transported by the temporary elevators 10a to 10c.

[0022] Next, with reference to Fig. 3, Fig. 4A and Fig. 4B, the method of transporting materials and the like at the construction site of this embodiment will be described. Fig. 3 is a flowchart showing the method of transporting materials and the like (material transportation process) at the construction site.

[0023] First, it is determined whether unloading is necessary (step S1). If unloading is necessary, the process proceeds to the material temporary placement step in step S2. On the other hand, if unloading is not required, the process proceeds to step S3.

[0024] Here, the material temporary placement step will be described with reference to FIGS. 4A(a) to (c). The material temporary placement step is a step of temporarily placing materials and the like loaded on a vehicle at a material temporary placement site. In the material temporary placement step, as shown in FIG. 4A(a), the material basket 22 of the material conveyor elevator 21 is stopped on the first floor and the first door 23a is opened. In the unloading yard 30 on the first floor, vehicles 60a loaded with material X (materials and the like) and vehicles 60b loaded with material Y (materials and the like) stop. Subsequently, forklifts 70a and 70b, which are examples of cargo handling machines, unload the material X loaded on the vehicle 60a and the material Y loaded on the vehicle 60b. The material X and material Y unloaded by the forklifts 70a and 70b are respectively held by the forklifts 70a and 70b and loaded into the material basket 22. Note that the cargo handling machine is not limited to a forklift, and any machine capable of transporting and lifting goods may be used. Further, the cargo handling machine may be configured to perform automatic traveling and automatic cargo handling under the control of a control device. Also, in the case of materials with a light weight, the materials may be unloaded onto a trolley and carried into the material basket 22, or a person may carry the materials by hand and carry them into the material basket 22.

[0025] Next, as shown in FIG. 4A(b), when the loading of materials X and Y into the material basket 22 is completed, the first door 23a is closed, and the material basket 22 is moved to the second floor or the basement first floor by the material conveyor elevator 21 to transport the materials X and Y.

[0026] Next, as shown in FIG. 4A(c), when the material basket 22 loaded with materials X and Y arrives at the second floor or the basement first floor, the second door 23b is opened. At the second floor or the basement first floor, a forklift 70c, which is an example of a transport vehicle, is waiting. The materials X and Y are unloaded from the material basket 22 by the forklift 70c, and the unloaded materials X and Y are temporarily placed at the temporary material storage area 40. Note that the transport vehicle here is not limited to a forklift, and the above-described cargo handling machine may also be used. Further, the transport vehicle may automatically travel along a route according to the rail, the guide, or the like by using the rail, the guide, or the like.

[0027] In the material temporary storage step of the present embodiment, the unloaded materials and the like are preferentially temporarily stored in the temporary material storage area 40 provided on the second floor. When it becomes difficult to temporarily store materials or the like in the temporary material storage area 40 provided on the second floor (for example, there is no temporary storage space), or when this step becomes inefficient only by transporting materials or the like to the second floor because there are many materials or the like that need to be unloaded, the materials or the like are temporarily stored in the temporary material storage area 40 provided on the basement first floor. Note that the priority order of the plurality of temporary material storage areas 40 when the temporary material storage area 40 is provided on a plurality of floors may be determined by the on-site judgment as appropriate.

[0028] Returning to FIG. 3, in step S3, it is determined whether or not to move the materials temporarily stored in the temporary material storage area 40. If the temporarily stored materials are to be moved, the process proceeds to step S4. On the other hand, if the temporarily stored materials are not to be moved, the process returns to step S1.

[0029] In step S4, it is determined whether or not an operator is working. If the operator is working, the process returns to step S1. On the other hand, if the operator is not working, the process proceeds to the material transport step (step S5). Note that the case where the operator is not working includes any one or more of nighttime, holidays, and break times outside of working hours, as long as it is a time zone when the operator does not use the temporary elevator 10. When the material transport step (step S5) is completed, the process proceeds to the material conveyance step (step S6).

[0030] Here, the material transportation process will be described with reference to FIGS. 4B(d) and (e), and the material conveyance process will be described with reference to FIG. 4B(f).

[0031] The material transportation process is a process of transporting the materials temporarily placed in the temporary material storage area to the floor (destination floor) where these materials are to be used. In the material transportation process, as shown in FIG. 4B(d), when moving the materials X and Y in the temporary material storage area 40 on the second floor, for example, the carriages 11a and 11b of two of the three temporary elevators 10a to 10c (a part) are stopped on the second floor, and their respective car doors are opened. Subsequently, the material Y in the temporary material storage area 40 is loaded into the carriage 11a by the forklift 70c, and the material X in the temporary material storage area 40 is loaded into the carriage 11b by the forklift 70c. Whether to use all of the temporary elevators 10a to 10c or one or two of the temporary elevators 10a to 10c for transporting the temporarily placed materials etc. may be determined appropriately on site.

[0032] Next, as shown in FIG. 4B(e), when the loading of the material Y into the carriage 11a or the loading of the material X into the carriage 11b is completed, their respective car doors are closed, and the carriages 11a and 11b are moved to the destination floor, for example, the tenth floor, by the temporary elevators 10a and 10b to transport the materials X and Y.

[0033] The material transportation process is a process of placing the materials and the like transported to the target floor in the material storage area provided on the target floor. In the material transportation process, as shown in FIG. 4B(f), when the cage 11a carrying the material Y or the cage 11b carrying the material X arrives at the 10th floor, the respective cage doors are opened. On the 10th floor, handlifts 80a to 80c, which are an example of a transport vehicle, and their respective operators 90a to 90c are waiting. Then, the operator 90a operates the handlift 80a to transport the material Y to the material storage area 51 and places the transported material Y in the material storage area 51. Also, the operator 90b operates the handlift 80b to transport the material Y to the material storage area 52 and places the transported material Y in the material storage area 52. Further, the operator 90c operates the handlift 80c to transport the material X to the material storage area 53 and places the transported material X in the material storage area 53. Note that the transport vehicle here is as described above.

[0034] Note that each of the material conveyance process (step S5) and the material transportation process (step S6) is a process that is repeatedly executed when the material X (Y) that still needs to be transported to the material storage area 51 (52, 53) is in the temporary material storage area 40.

[0035] As described above, in the present embodiment, a temporary material storage area 40 is provided on an adjacent floor (the 2nd floor or the basement 1st floor) adjacent to the unloading floor (the 1st floor), and a temporary structure 20 equipped with a material conveyance elevator 21 is installed from the unloading floor to the adjacent floor inside the building under construction (for example, the high-rise building 1). Then, by transporting the materials and the like used in the construction to the adjacent floor by the material conveyance elevator 21, the materials and the like can be temporarily placed in the temporary material storage area 40 provided on the adjacent floor. Therefore, it is not necessary to secure a traffic line for vehicles to pass through, and it is possible to provide a large temporary storage area on the adjacent floor where the passage of workers is relatively less than that on the unloading floor, so the work efficiency of temporarily placing materials and the like is improved. Also, it is not necessary to provide a temporary storage area on the unloading floor, or the space of the temporary storage area provided on the unloading floor can be reduced so as not to interfere with construction work or the passage of workers related to the work.

[0036] Also, when the material transfer elevator 21 is not installed, in addition to the movement of the workers, the temporary elevators 10 (10a, 10b, 10c) will be used for the transfer of materials and the like. Therefore, in order to ensure the transfer ability of materials and the like without reducing the movement ability of the workers, it is necessary to add one more temporary elevator 10. In contrast, in this embodiment, by installing the material transfer elevator 21 instead of one temporary elevator 10, it is possible to ensure the transfer ability of materials and the like without reducing the movement ability of the workers.

[0037] In addition, since the installation range of the temporary structure 20 equipped with the material transfer elevator 21 is not extended to the upper floors such as the nth floor but only to the adjacent floors, the amount of materials for installing the temporary structure 20 can also be reduced, and the installation working time of the temporary structure 20 and the dismantling working time of the unnecessary temporary structure 20 can be suppressed to a short time. Also, the installation work of the floor and ceiling after dismantling the temporary structure 20 is limited to the load unloading floor and the adjacent floors. Also, the decrease in strength, rigidity, etc. caused by forming a cavity up to the upper floors such as the nth floor in the building can be suppressed. Therefore, while minimizing the negative factors for the construction of the building caused by extending the installation range of the temporary structure 20 installed for the purpose of temporarily placing materials and the like up to the upper floors such as the nth floor, the efficiency of the temporary placement work of materials and the like can be improved. Thus, considering the entire construction of the building, it is possible to shorten the construction period and working time related to the construction.

[0038] <Second Embodiment> Next, the material transfer system and the material transfer process according to the second embodiment of the present disclosure will be described with reference to FIG. 5. In the second embodiment, the configurations different from those in the first embodiment will be described, and the description of the same configurations as those in the first embodiment will be omitted.

[0039] In the above-described first embodiment, the temporary structure was installed inside the high-rise building. However, it is not limited to this, and the temporary structure may be installed outside the high-rise building.

[0040] As shown in Fig. 5(a), outside a high-rise building 100 under construction, which is an example of a construction site, a temporary structure (temporary construction platform) 200 is installed adjacent to the high-rise building 1. The temporary structure 200 is a two-story temporary structure installed over a height corresponding to the first to second floors of the high-rise building 1. Note that in the overlapping area between the high-rise building 1 and the temporary structure 200, since the outer wall and the like are not installed, vehicles such as forklifts can pass through. The temporary structure 200 is provided with a material transport elevator (material transport EV) 210, which is an example of an elevator. The material transport elevator 210 is provided with a material basket 220 for loading materials and the like. Note that the standby position of the material basket 220 is on the first floor. The material transport elevator 210 raises and lowers the material basket 220 between the first floor, which is the unloading floor, and the second floor, which is the adjacent floor, by a driving device.

[0041] Fig. 5(b) is a plan image view of the first floor, which is the unloading floor where the unloading work of materials is carried out from a vehicle loaded with materials and the like. As shown in this figure, a unloading yard 300, which is a space for unloading materials and the like, is provided on the first floor of the temporary structure 200. In addition, the material basket 220 is provided with a door 230 that is opened and closed by a driving device on the side facing the unloading yard 300.

[0042] Fig. 5(c) is a plan image view of the second floor, which is the adjacent floor adjacent to the first floor, which is the unloading floor. As shown in this figure, the temporary structure 200 is provided on the second floor with a material temporary storage area 400, which is a space for temporarily placing the materials transported by the material transport elevator 210. In addition, the material temporary storage area 400 is provided at a position facing the door 230. Note that the method of transporting materials and the like (material transport process) in the second embodiment is substantially the same as that in the first embodiment, but the difference is that the door 230 of the material basket 220 is opened and closed when loading materials into the material basket 220 on the first floor or unloading materials from the material basket 220 on the second floor.

[0043] As described above, in the present embodiment, a temporary structure 200 is installed outside a building under construction (for example, high-rise building 100) and includes a material transport elevator 210 that moves up and down between the unloading floor and the adjacent floor. Then, an unloading yard 300 is provided on the unloading floor (1st floor) inside the temporary structure 200, and a material temporary storage area 400 is provided on the adjacent floor (2nd floor) inside the temporary structure 200, so that materials and the like can be unloaded outside the building and temporarily stored outside the building. Therefore, since materials can be unloaded and temporarily stored outside the building, where it is less affected by the passage of vehicles and workers compared to the inside of the building, the work efficiency of temporarily storing materials and the like is improved.

[0044] In addition, since the installation range of the temporary structure 200 equipped with the material transport elevator 210 is limited to the adjacent floor without extending to the upper floors such as the nth floor, the amount of materials for installing the temporary structure 200 can also be reduced, and the installation work time of the temporary structure 200 and the demolition work time of the unnecessary temporary structure 200 can be suppressed to a short time. Also, since the temporary structure 200 is installed outside the building, the construction work after the demolition of the temporary structure 200 is also limited to areas that overlap with the temporary structure 200. Therefore, while minimizing the negative factors on the construction of the building caused by the temporary structure 200 installed for the purpose of temporarily storing materials and the like on the adjacent floor, the efficiency of the work of temporarily storing materials and the like can be improved. Thus, considering the entire construction of the building, it is possible to shorten the construction period and work time related to the construction.

[0045] <Third Embodiment> Next, a material transport system and a material transport process according to the third embodiment of the present disclosure will be described with reference to FIGS. 6 and 7(a). In the third embodiment, only the configurations different from those of the first and second embodiments will be described, and the descriptions of the same configurations as those of these embodiments will be omitted.

[0046] In the above-described first and second embodiments, the temporary structure 20 was installed inside or outside the high-rise building 1. However, the present invention is not limited to this, and the temporary structure may not be installed.

[0047] As shown in FIGS. 6(a) and 6(c), a material loading entrance 1100 is provided in an area where the outer wall is not installed on the second floor of the high-rise building 1000 under construction, which is an example of a construction site. And a temporary material storage area 4000 is provided on the second floor of the high-rise building 1000. Further, as shown in FIG. 6(b), a unloading yard 3000 is provided on the site corresponding to the first floor outside the high-rise building 1000.

[0048] In the method of transporting materials (material transportation process) of the present embodiment, the material temporary storage process (step S2) in the above-described material transportation process (see FIG. 3) becomes a different process as follows, but the other processes are the same.

[0049] FIG. 7(a) is a diagram showing the material temporary storage process in the material transportation process of the present embodiment. As shown in this figure, in the material temporary storage process, vehicles 60a (vehicles 60b loaded with material Y) etc. loaded with material X (materials etc.) stop at the unloading yard 3000. Subsequently, a telescopic boom and a telehandler 5000 equipped with a pallet fork (or bucket) etc. at the tip of the boom, which is an example of a loading and unloading machine, unloads the material X (Y) loaded on the vehicle 60a (60b).

[0050] Subsequently, the unloaded material X (Y) is lifted to the second floor by the telehandler 5000 and carried in from the material loading entrance 1100. The material X (Y) carried in from the material loading entrance 1100 is transported by a forklift 70c and temporarily stored in the temporary material storage area 4000. Note that the loading and unloading machine is not limited to a telehandler, and any machine having a function of lifting a load to an upper floor such as the second floor like a crane truck etc. may be used. Also, it is possible to use a loading and unloading machine for unloading materials etc. and a hoisting machine for lifting the unloaded materials etc. to the second floor. Also, the transporter is not limited to a forklift. For example, in the case of materials with a light weight, a person may use a hand truck or a trolley etc. to transport the materials etc. Also, some or all of the loading and unloading machine, hoisting machine, and transporter may be configured to perform automatic running, automatic loading and unloading, or automatic transportation under the control of a control device.

[0051] As described above, in the present embodiment, a unloading yard 3000 corresponding to the first floor is provided on the site outside the building under construction (for example, high-rise building 1000). In addition, a material entrance 1100 and a temporary material storage area 4000 are provided on the second floor, so that materials and the like are unloaded at the unloading yard 3000 by a handling machine, and the materials and the like are lifted to the second floor by the handling machine. Then, the materials and the like lifted to the second floor are temporarily placed in the temporary material storage area 4000 by a transporter. Therefore, it is possible to unload materials outside the building where it is difficult to be affected by the passage of vehicles and workers compared to the inside of the building, and the unloaded materials can be temporarily placed on the adjacent floors from the outside, so the work efficiency of temporarily placing materials and the like is improved. In addition, the efficiency of the temporary placement work of materials and the like can be improved without installing the temporary structure 20 (200). Therefore, when considering the entire construction of the building, it is possible to shorten the construction period and working hours related to the construction.

[0052] <Fourth Embodiment> Next, the material transportation process according to the fourth embodiment of the present disclosure will be described with reference to FIG. 7(b). In the fourth embodiment, different configurations from the first to third embodiments will be described, and descriptions of the same configurations as these embodiments will be omitted.

[0053] In the material transportation system according to the fourth embodiment, different configurations from the material transportation system according to the third embodiment (see FIG. 6) are that there is no material entrance 1100 on the second floor, there are temporary material storage areas 4000 on the second floor and the basement first floor, and a temporary elevator 10 (10a to 10c) is used when temporarily placing the unloaded materials. When the temporary elevator 10 (10a to 10c) is used for temporarily placing materials, the usage range is restricted (operated or controlled (set)) to the floors where the temporary material storage area 4000 is provided, such as from the second floor to the basement first floor. Alternatively, one or several of the temporary elevators 10a to 10c can be used for temporarily placing materials (used in combination with the use by workers or dedicated).

[0054] In the method for transporting materials and the like (material transportation process) of the present embodiment, the material temporary storage process (step S2) in the above-described material transportation process (see FIG. 3) becomes a different process as follows, but the other processes are the same.

[0055] FIG. 7(b) is a diagram showing the material temporary storage process in the material transportation process of the present embodiment. As shown in this figure, in the material temporary storage process, vehicles 60a (vehicles 60b loaded with material Y) loaded with material X (materials and the like) stop at the unloading yard 3000. Subsequently, a forklift 70a (70b), which is an example of a handling machine, unloads the material X (Y) loaded on the vehicle 60a (60b).

[0056] Subsequently, the unloaded material X (Y) is loaded into the car body 11 of the temporary elevator 10 waiting on the first floor by the forklift 70a (70b). Then, by moving the car body 11 to the second floor by the temporary elevator 10, the material X (Y) is transported to the second floor. The material X (Y) transported to the second floor is unloaded from the car body 11 by the forklift 70c, transported, and temporarily stored in the material temporary storage area 4000. Also, by moving the car body 11 to the basement first floor by the temporary elevator 10, the material X (Y) is transported to the basement first floor. The material X (Y) transported to the basement first floor is unloaded from the car body 11 by the forklift 70c, transported, and temporarily stored in the material temporary storage area 4000. Note that the handling machine and the transporter may be those described above.

[0057] As described above, in this embodiment, a unloading yard 3000 corresponding to the first floor is provided on the site outside the building under construction (for example, high-rise building 1000). Further, by providing a temporary material storage area 4000 on the second floor and the basement first floor, materials and the like are unloaded at the unloading yard 3000 by a handling machine and loaded into the car 11 of the temporary elevator 10, and the temporary elevator 10 transports the materials and the like to the second floor and the basement first floor. Then, the materials and the like transported to the second floor and the basement first floor are temporarily placed in the temporary material storage area 4000 by a transporter. Therefore, it is possible to unload materials outside the building, which is less affected by the passage of vehicles and workers compared to the inside of the building. In addition, by restricting the use range of the temporary elevator and using it for transportation to temporarily place the unloaded materials, it is possible to temporarily place materials and the like on the adjacent floors, so that it is possible to improve the work efficiency of temporarily placing materials and the like while suppressing the influence on the movement of workers. In addition, the efficiency of the temporary placement work of materials and the like can be improved without installing the temporary structure 20 (200). Therefore, when considering the entire construction of the building, it is possible to shorten the construction period and working hours related to the construction.

[0058] <Effects of the embodiment> As described above, according to these embodiments, regardless of whether the workers involved in the construction of the building are working or not, it is possible to unload the materials and the like loaded on the vehicle. And the unloaded materials and the like can be efficiently temporarily placed in the temporary material storage area provided on the adjacent floor, which is less affected by the passage of vehicles and workers adjacent to the unloading floor. In addition, since it is possible to secure a wider space for the temporary material storage area than the unloading floor, it is possible to bring in more materials and the like.

[0059] Also, according to these embodiments, materials and the like temporarily placed in the material storage area are conveyed to a floor above the adjacent floor outside the working hours of the workers by the temporary elevator 10 used by the workers involved in the construction of the building. Therefore, the waiting time of the workers for the temporary elevator during working hours can be reduced. Also, the waiting time of the temporary elevator during the workers' arrival time, departure time, or break time can be decreased, and the congestion due to waiting for the temporary elevator can be alleviated. Also, regarding the conveyance of the temporarily placed materials and the like to the upper floors, since it is not affected by the use of the temporary elevator by the workers, the materials and the like can be efficiently conveyed to the upper floors.

[0060] Also, according to these embodiments, by installing the material conveyance elevators 21, 210, the material conveyance elevators 21, 210 can be used as dedicated elevators for conveying the unloaded materials and the like to the adjacent floors. Also, by installing the material conveyance elevators 21, 210, during working hours, the temporary elevator 10 can be made a dedicated or priority elevator for the workers. Therefore, it is possible to improve the conveyance efficiency of the unloaded materials and the like and the movement efficiency of the workers.

[0061] <Modification example etc.> In the material conveyance elevator 21 in the first embodiment, by providing two doors (the first door 23a, the second door 23b), the first door 23a is opened to load materials and the like into the material basket 22, and the second door is opened to unload materials and the like from the material basket 22. However, it is not limited to this, and only one of the first door 23a and the second door 23b may be provided. Also, in the material conveyance elevator 210 in the second embodiment, by providing one door (door 230), the door 230 is opened to load and unload materials and the like into and from the material basket 22. However, it is not limited to this, and two doors may be provided.

[0062] Also, in the material conveyor elevator 21 in the first embodiment, a first door 23a and a second door 23b are provided on the material basket 22, and in the material conveyor elevator 210 in the second embodiment, a door 230 is provided on the material basket 220. However, it is not limited to this, and each door (23a, 23b, 230) may not be provided on the material baskets 22 and 220, or each door (23a, 23b, 230) may be provided at each stop floor of the material baskets in the material conveyor elevators 21 and 210.

[0063] Also, in the first embodiment, the temporary structure 20 was installed from the basement floor 1 to the second floor. However, it is not limited to this, and the temporary structure 20 may be installed from the first floor to the second floor, or from the first floor to the basement floor 1.

[0064] Also, in the second embodiment, the temporary structure 200 was installed from the first floor to the second floor. However, it is not limited to this. When there is space such as a site outside corresponding to the basement floor 1 of the high-rise building 100, the temporary structure 200 may be installed from the first floor to the basement floor 1, or from the second floor to the basement floor 1. By doing so, it becomes possible to use the basement floor 1 as a temporary storage place for materials.

[0065] In the first embodiment, a temporary material storage area 40 was provided on an adjacent floor (e.g., the 2nd floor or the basement 1st floor) of the unloading floor (e.g., the 1st floor). In the second embodiment, a temporary material storage area 400 was provided on an adjacent floor (e.g., the 2nd floor) of the unloading floor (e.g., the 1st floor). Thus, the temporary structure 20 (200) was installed across the unloading floor and the adjacent floor. However, it is not limited to this. The temporary material storage area 40 may be provided on an adjacent floor (e.g., the 2nd floor) of the unloading floor (e.g., the 1st floor) and on floors above the adjacent floor (e.g., the 3rd floor and above). Also, the temporary material storage area 40 may be provided on an adjacent floor (e.g., the basement 1st floor) of the unloading floor (e.g., the 1st floor) and on floors below the adjacent floor (e.g., the basement 2nd floor and below). In such a case, the temporary structure 20 (200) may be installed across the unloading floor, the adjacent floor, and a floor above or below the adjacent floor. In addition, in such a case, considering the labor and time involved in installing 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 material storage area 40 (400) is provided be up to the floors excluding the high-rise floors of the building.

[0066] Also, in the third embodiment, the temporary material storage area 4000 was provided on the adjacent floor (for example, the second floor) of the unloading floor (for example, the first floor). However, it is not limited to this, and the temporary material storage area 4000 may be provided on the adjacent floor (for example, the second floor) of the unloading floor (for example, the first floor) and the upper floors above the adjacent floor (for example, the third floor and above). In this case, considering which cargo handling machine (crane) to use or how much temporary storage space needs to be secured, etc., it may be appropriately determined according to the construction site on which floor to provide the temporary material storage area 4000. Also, the temporary material storage area 4000 and the material loading and unloading entrance 1100 may be provided on the adjacent floor (for example, the basement first floor) of the unloading floor (for example, the first floor). In this case, for example, it is conceivable to lower and carry in the materials unloaded using a crane or the like from the first floor to the basement first floor. Also, the temporary material storage area 4000 and the material loading and unloading entrance 1100 may be provided on the lower floors below the adjacent floor (for example, the basement second floor and below) adjacent to the adjacent floor (the basement first floor), and the materials unloaded by a crane or the like may be lowered and carried in from the first floor to the basement second floor.

[0067] Also, in the fourth embodiment, the temporary material storage area 4000 was provided on the adjacent floors (for example, the second floor and the basement first floor) of the unloading floor (for example, the first floor). However, it is not limited to this, and the temporary material storage area 4000 may be provided on the adjacent floor (for example, the second floor) of the unloading floor (for example, the first floor) and the upper floors above the adjacent floor (for example, the third floor and above), or on the adjacent floor (for example, the basement first floor) of the unloading floor (for example, the first floor) and the lower floors below the adjacent floor (for example, the basement second floor and below). In this case, considering the degree of influence on the movement of the workers, it may be appropriately determined according to the working environment of the construction site on which floor to provide the temporary material storage area 4000.

[0068] Also, 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 in combination. That is, both the method of loading the unloaded materials etc. into the material entrance 1100 by a cargo handling machine etc. and the method of loading using the temporary elevator 10 may be adopted so that the materials etc. can be temporarily stored at the material temporary storage areas 4000 on each floor. In such a case, either method may be adopted or both methods may be adopted for loading considering the size, weight of the materials etc. to be loaded and the labor (time) involved in loading, or either method may be adopted or both methods may be adopted for loading considering the usage status of the temporary elevator by the workers within the working hours. By doing so, the efficiency of the material temporary storage process is improved, and thus the efficiency of the entire material transportation process is also improved.

[0069] In the first to fourth embodiments, the unloading floor is the first floor. However, it is not limited to this, and the unloading floor may be a floor on the second floor or higher of the building, or a floor on the first basement floor or lower. And in the first and second embodiments, for example, when the unloading floor is the second floor of the building, the temporary structure 20(200) is installed across the second floor and its adjacent floor, and for example, when 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 floor.

[0070] In the second embodiment, the temporary structure 200 is provided with an elevator (material transportation elevator 210). However, it is not limited to this, and the temporary structure 200 may not be provided with an elevator. In such a case, the materials etc. may be lifted by construction machinery such as a crane, a telehandler, or a large forklift from the unloading floor (the first floor) to the adjacent floor (the second floor) or a floor above the adjacent floor (the third floor or higher floors) and then carried into the material temporary storage areas 400 provided on the adjacent floor or a floor above the adjacent floor. By doing so, the materials for installing the temporary structure 200 can be reduced, and the time required for installing and dismantling the temporary structure 200 can be shortened.

[0071] In addition, in the second embodiment, the temporary structure 200 was provided with a material temporary storage area 400. However, it is not limited to this, and the temporary structure 200 may not be provided with the material temporary storage area 400, and the space may be provided inside the building in the same manner as in the first embodiment. By doing so, the materials for installing the temporary structure 200 can be reduced, and the time required for installing and dismantling the temporary structure 200 can be shortened.

[0072] Also, in the material transportation process (step S5) in the first and second embodiments, the temporary elevator 10 was used as the elevator. However, it is not limited to this. For example, if elevators such as the permanent elevator used by the users of the high-rise building 1 after the dismantling of the temporary elevator or the luggage transportation elevator used by the users to transport luggage are already installed (the workers use these permanent elevators, etc.), in the material transportation process (step S5), these permanent elevators, etc. may be used.

[0073] Also, when transporting waste, unnecessary materials, work machines, dismantled temporary structures, etc. (hereinafter referred to as waste, etc.) generated by construction work on the upper floors than the adjacent floors to the unloading floor, the material transportation system in the first embodiment and the second embodiment can be used. In this case, the workers carry the waste, etc. into the temporary elevator 10 by a transport vehicle, etc. outside the working hours, the temporary elevator 10 transports the waste, etc. from the upper floor to the adjacent floor, and the waste, etc. are temporarily placed in the material temporary storage area 40 (400) on the adjacent floor by a transport vehicle, etc. Then, during the working hours of the workers, the waste, etc. temporarily placed are carried into the material transportation elevator 21 (210) by a transport vehicle, etc., and the material transportation elevator 21 (210) transports the waste, etc. from the adjacent floor to the unloading floor. Subsequently, the waste, etc. are unloaded from the material transportation elevator 21 (210) by a loading and unloading machine, etc., and loaded onto the transport vehicle waiting in the unloading yard 30 (300). Note that the waste, etc. may be transported from the upper floor to the unloading floor by the temporary elevator 10 outside the working hours of the workers.

[0074] In addition, when transporting such waste to the unloading floor, the material transportation system of the third embodiment can be used. In such a case, outside the working hours of the operator, the waste is carried into the temporary elevator 10 by a transport vehicle or the like, the waste is transported from the upper floor to the adjacent floor by the temporary elevator 10, and the waste is temporarily placed in the material temporary storage area 4000 on the adjacent floor by a transport vehicle or the like. Then, during the working hours of the operator, the waste temporarily placed by a transport vehicle or the like is transported to the material loading entrance 1100, and the waste is lifted and lowered from the adjacent floor to the unloading floor by a cargo handling machine or the like. Subsequently, the waste is loaded onto the transport vehicle waiting in the unloading yard 3000 by a cargo handling machine or the like. Note that the waste may be transported from the upper floor to the unloading floor by the temporary elevator 10 outside the working hours of the operator.

[0075] In addition, when transporting such waste to the unloading floor, the material transportation system of the fourth embodiment can be used. In such a case, outside the working hours of the operator, the waste is carried into the temporary elevator 10 by a transport vehicle or the like, the waste is transported from the upper floor to the adjacent floor by the temporary elevator 10, and the waste is temporarily placed in the material temporary storage area 4000 on the adjacent floor by a transport vehicle or the like. Then, during the working hours of the operator, the waste temporarily placed by a transport vehicle or the like is carried into the temporary elevator 10, and the waste is transported from the adjacent floor to the unloading floor by the temporary elevator 10. Subsequently, the waste is loaded onto the transport vehicle waiting in the unloading yard 3000 by a cargo handling machine or the like. Note that the waste may be transported from the upper floor to the unloading floor by the temporary elevator 10 outside the working hours of the operator.
