Description

The present invention relates to an in-building ceiling transport system and a method for installing an in-building ceiling transport rail.

Conventionally, in clean rooms in semiconductor factories, ceiling transport equipment is known that automatically transports wafers using a ceiling transport rail installed on the ceiling surface as a track to store the wafers as they move between semiconductor devices.

Here, suspended ceilings are often used as ceilings for buildings such as clean rooms. Such suspended ceilings are comprised of a number of rafters arranged in parallel at a given interval in one horizontal direction, a number of rafter supports arranged in parallel at a given interval in the other horizontal direction perpendicular to the rafters and integrally connected to the rafters, a number of hanging bolts (hanging members) whose lower ends are connected to the rafter supports and whose upper ends are fixed to the upper structure (building frame) such as flooring on the upper floor, and a ceiling panel that is integrally attached to the underside of the rafters by screws or the like and forms the ceiling surface of the lower floor (see, for example, Patent Document 1).

JP 2013-177801 A

However, the conventional method of installing ceiling transport equipment in a ceiling structure as disclosed in Patent Document 1 has the following problems.
That is, conventional ceiling conveyor rails are installed on ceiling panels, or a dedicated suspension point for the ceiling conveyor rail is separately installed on the top surface of the ceiling frame such as the ceiling panel base material. Therefore, the construction of the ceiling conveyor equipment starts after the construction of the ceiling panel and the dedicated suspension point is completed, which causes a problem of a long construction period. For example, as mentioned above, when it is adopted in a clean room in a semiconductor factory, there are cases where the operation time of semiconductor devices is earlier than the completion of the ceiling conveyor equipment. In other words, until the ceiling conveyor equipment is completed, workers have to transport using carts, etc., which reduces production efficiency, and there is room for improvement in this respect.

In addition, in conventional construction, high precision is required for the installation position of the storage unit relative to the semiconductor device, so high precision is also required for the installation of the ceiling transport rail of the ceiling transport equipment. As a result, the precision of the ceiling transport rail is determined by the positional relationship between the ceiling frame from which it is suspended and the hanging bolts, and position adjustment takes a lot of time. Moreover, because the position adjustment work needs to be done at the same time as the construction of the ceiling transport rail, it has been difficult to reduce the time required for one work process.

In addition, in the case of overhead transport equipment in semiconductor factories, the layout of the semiconductor device is often changed, and the rail tracks must be corrected and precisely adjusted to match the layout change. In other words, to change the position of the overhead transport rail, it is necessary to loosen the fixing bolts of the raceway attached to the ceiling frame, adjust the position, and then retighten all the bolts to fix them in place.
Furthermore, if major changes were to be made to the layout, the system would need to be removed from the raceway itself, necessitating larger-scale construction work, including adjustment work.

The present invention has been made in consideration of the above-mentioned problems, and aims to provide an in-building ceiling conveying system and an in-building ceiling conveying rail construction method that eliminate the need for a dedicated hanging point for the ceiling conveying rail, and that allows the ceiling conveying rail to be installed without the need for a dedicated hanging point or the construction of a ceiling panel, thereby shortening the construction period.
Another object of the present invention is to provide an in-building ceiling conveying system and an installation method for an in-building ceiling conveying rail that can efficiently and simply correct the trajectory of the ceiling conveying rail and adjust its position with high precision.
It is still another object of the present invention to provide an in-building ceiling transport system and an in-building ceiling transport rail installation method that allow easy changes to the equipment layout.

To achieve the above object, the in-building ceiling transport system of the present invention is an in-building ceiling transport system equipped with a ceiling transport rail for transporting items to the top surface of the building structure, and is equipped with a plurality of side bars supported on the top surface of the structure, extending in a second direction perpendicular to a first direction in which the ceiling transport rail extends, and spaced apart in the first direction, and a unit frame in which the ceiling transport rails are connected from above to form a unit and extend in the first direction, the unit frame is provided so as to be movable in the first direction, the second direction, and the up-down direction relative to the plurality of side bars, and is supported in a state in which it is suspended from the side bars at a predetermined position that has been adjusted.

The method for constructing an in-building ceiling conveyor rail according to the present invention is a method for constructing an in-building ceiling conveyor rail for conveying goods on the top surface of the building's framework, and is characterized by comprising the steps of: providing a plurality of side bars that are supported on the top surface of the framework and extend in a second direction perpendicular to the first direction of the ceiling conveyor rail and spaced apart in the first direction; providing a conveyor rail unit that is unitized by connecting the ceiling conveyor rail from above with a unit frame that extends in the first direction; and placing the unit frame equipped with the ceiling conveyor rail above the plurality of side bars and moving it in the first direction, the second direction, and up and down to adjust its position, and supporting it in a suspended state relative to the side bars at a predetermined position.

In this invention, the side bars that support the unit frame that unitizes the ceiling transport rail in a suspended state are supported on the top surface of the structure, so that once construction of the top surface of the structure is completed, the side bars can be attached to the top surface of the structure and the ceiling transport rail can be constructed together with the unit frame. This eliminates the need for a dedicated suspension point for the ceiling transport rail, and the ceiling transport rail can be installed regardless of the construction of a dedicated suspension point or ceiling panel. In other words, the ceiling transport rail can be constructed before the completion of the dedicated suspension point and ceiling panel, shortening the construction period.

In addition, in the present invention, the unit frame is positioned in a state in which it can be guided relative to multiple side bars, so that the unit frame can be easily moved in the first and second directions relative to the side bars, and can also be moved in the vertical direction. In this way, the position of the unit frame can be adjusted efficiently and with high precision through simple work, and the construction period can be shortened.

Furthermore, in the present invention, in the case of minor changes to the equipment layout, the unit frame can be released from its fixation to the side bar, allowing the position of the unit frame to be adjusted in the first direction, second direction, and up and down direction. Even in the case of major layout changes that exceed the range of movement of the unit frame relative to the side bar, the construction period required for changing the equipment layout can be extended by bringing forward the installation of the ceiling transport rails. In this way, the present invention can provide high adaptability to changes in the equipment layout.

Furthermore, in this invention, the sidebars are attached to the ceiling of the structure or to the top surface of the structure, which is the ceiling space. This means that the sidebars can be installed at any desired height in the vertical direction, compared to the conventional method of installing ceiling transport rails on a ceiling panel or dedicated hanging point. Therefore, for example, if there is dead space in the ceiling, it is possible to place the sidebars and ceiling transport rails in this dead space, making effective use of the space.

The in-building ceiling transport system according to the present invention may also be characterized in that the top surface of the structure is provided with a suspended ceiling having ceiling panels supported by a suspended base frame, and the side bars are supported by the base frame.

In this case, since the side bars are supported by the base frame, which is the top surface of the structure, the side bars can be attached to the base frame once construction of the base frame is complete. This allows the ceiling transport rails to be installed on the side bars via the unit frame, and the ceiling transport rails can be installed before the ceiling panels installed on the base frame are completed, shortening the construction period.

The in-building ceiling transport system according to the present invention may also be characterized in that the side bars are provided with height adjustment members for adjusting the vertical height relative to the ceiling surface of the building structure.

In this case, when the unit frame is suspended and supported on the side bar, the vertical position of the unit frame can be easily adjusted using the height adjustment member.

The in-building ceiling transport system according to the present invention may also be characterized in that the unit frame is formed in a frame shape within a horizontal plane.

In this case, the frame-shaped unit frame is placed in a stable position relative to the multiple side bars, so the unit frame can be moved with precision by being guided by the side bars when adjusting its position.

The in-building ceiling transport system according to the present invention may also be characterized in that the side bars are arranged in multiple levels in the vertical direction, the lower level side bars are suspended from the upper level side bars directly above them or from the top surface of the structure by guide hanging materials, and the ceiling transport rails are provided on the lower level side bars.

In this case, it is possible to provide multiple layers of ceiling transport rails in the vertical direction.
Furthermore, as mentioned above, when the side bars and ceiling conveying rails are arranged in the dead space in the ceiling pocket to make the ceiling conveying rails multi-layered, there is no need to raise the ceiling panel to the position of the upper ceiling conveying rail as in the past, and then install the ceiling panel, thereby suppressing the increase in floor height.

The construction method for the in-factory ceiling transport system according to the present invention may also include a step of suspending a base frame from the top surface of the building's structure and providing a suspended ceiling with ceiling panels supported by the base frame, and may also include providing the plurality of side bars on the base frame.

The construction method for the in-factory ceiling transport system according to the present invention may also be characterized in that a transport cart capable of mounting the transport rail unit and running on the floor is provided, and the transport cart transports the transport rail unit to below the side bar at the installation position.

In this case, when installing the transport rail unit in a designated position on the ceiling, the transport rail unit can be loaded onto a transport cart and transported, and can be easily transported below the side bar at the installation position, improving construction efficiency.

According to the in-building ceiling conveying system and in-building ceiling conveying rail construction method of the present invention, a dedicated suspension point for the ceiling conveying rail is not required, and the ceiling conveying rail can be installed without the need for a dedicated suspension point or the construction of a ceiling panel, thereby shortening the construction period.
Furthermore, according to the present invention, trajectory correction and highly accurate position adjustment of the ceiling transport rail can be performed efficiently and with simple operations.
Furthermore, according to the present invention, the layout of the device can be easily changed.

Below, an embodiment of the in-building ceiling transport system and an in-building ceiling transport rail installation method according to the present invention will be described with reference to the drawings.

First Embodiment
The in-building ceiling transport system 1 according to this embodiment is an automatic transport equipment that is adopted in the ceiling of a semiconductor factory (building) such as a clean room, as shown in FIG. 1, and is equipped with ceiling transport rails 2 for transporting a storage section 2A that contains items (here, wafers) to the ceiling of the building.

The building ceiling transport system 1 comprises a suspended ceiling 10 having a ceiling panel 12 supported by a base frame 11 suspended from the building ceiling (top surface of the building structure) (not shown), a plurality of side bars 3 supported by the base frame 11 and extending in a second direction Y perpendicular to the first direction X, which is the extension direction of the ceiling transport rail 2, and spaced apart in the first direction X, and a unit frame 4 in which the ceiling transport rail 2 is connected from above to form a unit and extends in the first direction X.

Here, the ceiling conveying rail 2 of this embodiment is installed in an appropriate position depending on the layout of the semiconductor device, and the first direction X (as well as the second direction Y) indicating the extension direction of the ceiling conveying rail 2 is not limited to a specific direction. Moreover, the ceiling conveying rail 2 is provided so as to be changeable in accordance with changes in the layout of the semiconductor device.
In addition, the top surface of the structure refers to the area including the ceiling of the structure, the ceiling space, and the base materials installed in the ceiling space.

The suspended ceiling 10 has a number of hanging members 13 suspended from the top surface of the structure, a base frame 11 consisting of rafters and rafters supported via the hanging members 13, and a ceiling panel 12 attached below the base frame 11.

The hanging members 13 are long members that extend in the vertical direction, such as L-shaped steel members, with their upper ends fixed to and hanging down from the top surface of the structure, and their lower ends connected to the base frame 11 using a connecting jig or the like. The hanging members 13 are arranged at predetermined intervals in the horizontal direction.

The base frame 11 is installed in parallel at a predetermined interval in both the vertical and horizontal directions in a horizontal plane. The ceiling panel 12 is suspended from the underside of the base frame 11 using a connecting jig 14 and a hanging bolt 15.

As described above, the ceiling panel 12 forms a ceiling surface by connecting to a plurality of base frames 11 via connecting jigs 14 and hanging bolts 15 .
In the present embodiment, the ceiling panel 12 is formed with a recessed portion 12A so that the ceiling surface is elevated in the region where the ceiling transport rail 2 is disposed. Here, the recessed portion 12A has a top surface portion 121 and inner side surface portions 122 opposed to each other.

1 to 3, the ceiling transport rail 2 extends in one direction (first direction X) with a concave cross section that opens downward, and guides the storage section 2A capable of storing and holding articles. The ceiling transport rail 2 is formed of a top wall 21 and both side walls 22 as shown in FIG.
Convex portions 23 that protrude outward in the second direction are provided at a predetermined interval along the length of the ceiling transport rail 2 on the upper outer surfaces of both side walls 22. The multiple convex portions 23 are arranged at the same height on the ceiling transport rail 2. The lower ends of the vertical lifting members 43, which will be described later, are fixed to the upper surfaces 23a of the convex portions 23. The ceiling transport rail 2 is provided integrally with the unit frame 4 as a unit, as described above.

As shown in Fig. 1, the side bar 3 is made of a long steel material such as a raceway, an H-shaped steel, an L-shaped steel, or a channel steel, and is arranged with its flat surface (sliding surface 3a) facing upward. The side bar 3 is arranged to extend in the second direction Y in the recessed portion 12A of the ceiling panel 12, and is suspended from the base frame 11 by a suspension bolt 15 (see Fig. 2). The side bar 3 is arranged at a height close to the top surface portion 121 of the recessed portion 12A using a height adjustment member (not shown), and the height is determined so that the lower end 2a of the ceiling transport rail 2 suspended from the side bar 3 is located above the lower surface 12a of the ceiling panel 12.
A plurality of side bars 3 extending in the second direction Y are provided at intervals in the first direction X for one ceiling transport rail 2 (unit frame 4).

As shown in FIG. 2, the unit frame 4 is placed on the sliding surface 3a, which is the upper surface of the side bars 3, and is movable in the first direction X, the second direction Y, and the up-down direction Z, and is supported in a suspended state relative to the side bars 3 at a predetermined position that has been adjusted. As shown in FIG. 3, the unit frame 4 is made of long steel material such as a raceway, H-shaped steel, L-shaped steel, or channel steel, and is formed into a frame shape in a horizontal plane.

Specifically, as shown in FIG. 3, the unit frame 4 has a pair of vertical members 41 arranged in parallel with a gap between them, and three horizontal members 42 that connect the vertical members 41 to each other. The unit frame 4 is unitized with the ceiling conveyor rail 2 via the up-down lifting member 43 described below, with the vertical members 41 parallel to the longitudinal direction (first direction X) of the ceiling conveyor rail 2. Here, the unitized state in which the ceiling conveyor rail 2 is connected from above by the unit frame 4 extending in the first direction X is called the conveyor rail unit 40.

As shown in FIG. 3, the unit frame 4 is fixed to vertical lifting members 43 that protrude upward from both the left and right sides of the ceiling conveyor rail 2. The vertical lifting members 43 are provided between the ceiling conveyor rail 2 and the unit frame 4 so that their length in the vertical direction Z can be adjusted and fixed. The vertical lifting members 43 are bolt materials, and can be fixed to the unit frame 4 by fastening nuts (not shown) using bolt holes (not shown) formed in the unit frame 4. The position of the nuts relative to the vertical lifting members 43 can be adjusted to adjust the distance between the ceiling conveyor rail 2 and the unit frame 4, i.e., the heights of both.

As shown in Figures 3 and 4, when assembling the transport rail unit 40 to the side bar 3, a transport cart 5 capable of mounting the transport rail unit 40 and running on the floor is used. The transport cart 5 includes a running platform 52 having wheels 51, a pair of support pillars 53 erected upward from the left and right sides of the running platform 52, and a horizontal support member 54 that connects the upper ends of the support pillars 53 and extends in the second direction Y. The support pillars 53 are supported by the running platform 52 through a pair of diagonal supports 55. The unit frame 4 is placed on the horizontal support member 54. As shown in Figure 3, a long transport rail unit 40 can be transported by arranging multiple (here, three) transport carts 5 in the first direction X.

Next, a construction method for installing the ceiling transport rails 2 of the above-mentioned in-building ceiling transport system 1 will be specifically described with reference to the drawings.
First, as shown in Fig. 1, a suspended ceiling 10 is provided that includes a ceiling panel 12 supported by a base frame 11 suspended from the top surface of the building's framework. In this embodiment, once the installation of the base frame 11 is complete, the work of providing the side bars 3 on the base frame 11 begins.

As shown in FIG. 2, multiple hanging bolts 15 are provided on the base frame 11, and multiple side bars 3 are installed to extend horizontally at a predetermined height using these hanging bolts 15. At this time, the side bars 3 extend in a second direction Y perpendicular to the first direction X of the ceiling transport rail 2, and are arranged at intervals in the first direction X. Note that the hanging bolts 15 are used to suspend and support the ceiling panel 12, but the hanging bolts 15 in the area where the side bars 3 are to be installed may be installed first.

Next, in parallel with the above work, as shown in Fig. 3, a unitized transport rail unit 40 is formed in a state in which the ceiling transport rail 2 is connected from above by a unit frame 4 extending in the first direction X. The transport rail unit 40 is integrally assembled by attaching a plurality of protrusions 23 to the side walls 22 on both the left and right sides of the ceiling transport rail 2 at intervals in the first direction X, and fixing the unit frame 4 to the upper surfaces of the protrusions 23 via vertical lifting members 43.
The integrated transport rail unit 40 is then loaded onto a number of transport carts 5 and transported along the floor to a position below the side bar 3 where the transport rail unit 40 is to be installed.

Then, as shown in Figure 3, the conveying rail unit 40 is removed from the multiple transport carts 5, and the conveying rail unit 40 is raised using an aerial work vehicle 6 so that the unit frame 4 is above the multiple side bars 3, and the unit frame 4 is placed on the upper surfaces (sliding surfaces 3a) of these side bars 3.
In addition, the transport rail unit 40 may be placed on the side bar 3 while still attached to the transport cart 5.

Next, the position of the transport rail unit 40 is adjusted as shown in Figures 5(a), (b), and (c). Specifically, the position adjustment in the first direction X as shown in Figure 5(c) and the second direction Y as shown in Figure 5(b) is performed by sliding the unit frame 4 on the sliding surface 3a of the side bar 3. Then, the position adjustment in the vertical direction Z as shown in Figure 5(a) is performed by adjusting the position of a nut (not shown) of the vertical lift member 43. The transport rail unit 40 is supported in a suspended state, fixed to the side bar 3 at a predetermined position by a predetermined fixing means.
This completes the installation of the ceiling transport rail 2. Since the ceiling transport rail 2 is set to a predetermined length, it is installed by connecting the first direction X in an appropriate direction.

Next, the operation of the above-mentioned indoor ceiling transport system 1 and the method of installing the indoor ceiling transport rail will be described in detail with reference to the drawings.
In this embodiment, as shown in Figure 4, the side bars 3 that support the unit frame 4, which is a unitized version of the ceiling transport rail 2, in a suspended state are supported by the base frame 11 of the suspended ceiling 10.Therefore, once the construction of the base frame 11 is completed, the side bars 3 can be attached to the base frame 11, and the ceiling transport rail 2 can be constructed together with the unit frame 4.
Therefore, a dedicated suspension point for the ceiling conveyor rail is not required, and the ceiling conveyor rail 2 can be installed regardless of the construction of the dedicated suspension point or ceiling panel. In other words, the ceiling conveyor rail 2 can be installed before the dedicated suspension point or ceiling panel is completed, thereby shortening the construction period.

In addition, in this embodiment, the unit frame 4 is arranged in a state in which it can be guided relative to the multiple side bars 3, so that by guiding it along the sliding surface 3a on the upper surface of the side bar 3, the unit frame 4 can be easily moved in the first direction X shown in FIG. 5(c) and the second direction Y shown in FIG. 5(b), and can also be moved in the vertical direction Z shown in FIG. 5(c). In this way, the position of the unit frame 4 can be adjusted efficiently and with high accuracy through simple work, and the construction period can be shortened.

In addition, in this embodiment, in the case of minor changes to the device layout, the position of the unit frame 4 in the first direction X, the second direction Y, and the up-down direction Z can be adjusted by releasing the unit frame 4 from its fixed position relative to the side bar 3.
Furthermore, even when making a major layout change that exceeds the range of movement of the unit frame 4 relative to the side bar 3, it is possible to secure a longer construction period for changing the device layout by advancing the construction of the ceiling conveyor rails 2. In this manner, this embodiment can provide high adaptability to changes in the device layout.

Furthermore, in this embodiment, the side bar 3 is attached to the ceiling of the structure or to the top surface of the structure, which is the ceiling space. Therefore, compared to the conventional case where the ceiling transport rail is attached to a ceiling panel or a dedicated hanging point, the side bar 3 can be installed at any height in the vertical direction Z. Therefore, for example, if there is dead space in the ceiling pocket as in this embodiment, it is possible to place the side bar 3 and ceiling transport rail 2 in this dead space, making effective use of the space.

In addition, in this embodiment, when the unit frame 4 is suspended and supported by the side bar 3, the position of the unit frame 4 in the up-down direction Z can be easily adjusted using a height adjustment member (not shown) provided on the side bar 3.

Furthermore, in this embodiment, the unit frame 4 is formed in a frame shape in a horizontal plane, and the frame-shaped unit frame 4 is placed in a stable position relative to the multiple side bars 3, so that when adjusting the position of the unit frame 4, it can be moved with precision by being guided by the sliding surface 3a on the upper surface of the side bar 3.

In addition, in this embodiment, when installing the transport rail unit 40 at a specified position on the ceiling, the transport rail unit 40 can be loaded onto the transport cart 5 and transported, and can be easily transported below the side bar 3 at the installation position, thereby improving construction efficiency.

As described above, the construction of the ceiling conveyor rail 2 can be started before the construction of the ceiling panel 12, so that the use of the ceiling conveyor rail 2 can be started almost at the same time as the operation of the semiconductor manufacturing equipment, as in the case of a semiconductor manufacturing factory such as this embodiment, and production efficiency can be improved. In other words, since the construction of the ceiling conveyor rail 2 can be completed when the semiconductor manufacturing equipment is in operation, cleanliness control for construction, as in the case of installing and operating the semiconductor manufacturing equipment at the same time as the construction of the ceiling conveyor rail 2, is not required, and it is possible to reduce contamination measures for the clean room and improve construction efficiency. For example, since the construction of the ceiling conveyor rail 2 is not performed at the same time as the installation of the semiconductor manufacturing equipment and semiconductor manufacturing, workers can work in normal work clothes, improving the work environment, and since dust prevention measures are not required, equipment that emphasizes work efficiency can be used. Furthermore, only one layer of protective material is required for the ceiling conveyor rail 2, which reduces the effort and cost required for unpacking work.

In addition, by providing an air vent in the recessed portion 12A of the ceiling surface, the shape and the pressure difference between the clean room and the ceiling space (inside the ceiling chamber) can be used to efficiently attract dust into the ceiling space when the vehicle passes over the ceiling transport rail 2, preventing contamination of the clean room.

As described above, the building interior ceiling conveying system 1 and the construction method for the building interior ceiling conveying rail according to this embodiment eliminate the need for a dedicated hanging point for the ceiling conveying rail, and the ceiling conveying rail 2 can be installed without the need for a dedicated hanging point or the construction of a ceiling panel, thereby shortening the construction period.
Furthermore, in this embodiment, trajectory correction and highly accurate position adjustment of the ceiling transport rail 2 can be performed efficiently and simply.
Furthermore, in this embodiment, the layout of the device can be easily changed.

Second Embodiment
As shown in Fig. 6, the in-building ceiling transport system 1A in the second embodiment is configured with two layers of transport rail units 40 arranged above and below. Note that the above-mentioned first embodiment is an example in which one layer of ceiling transport rails 2 is installed at a position (recessed portion 12A) above the ceiling panel 12.

In the second embodiment of the building ceiling transport system 1A, the side bars 3 are arranged in two tiers in the vertical direction Z. The lower tier side bar 3B is suspended from the upper tier side bar 3A directly above it by a guide hanging material 31.

The upper side bar 3A is provided with a transport rail unit 40 in which the ceiling transport rail 2 is unitized with a unit frame 4. The lower side bar 3B is positioned lower than the storage section 2A (item) transported by the transport rail unit 40 provided on the upper side bar 3A. The ceiling transport rail 2 is fixed to the lower side bar 3B. The lower ceiling transport rail 2 is suspended from the lower side bar 3B via a fixture 24 without a unit frame 4.

In the case of the second embodiment, it is possible to make the ceiling conveying rail 2 multi-layered in the vertical direction Z. Also, when the ceiling conveying rail 2 is multi-layered by arranging the upper side bar 3A and the ceiling conveying rail 2 in the dead space of the ceiling pocket as in this embodiment, there is no need to raise the ceiling panel to the position of the upper ceiling conveying rail and install the ceiling panel as in the conventional case, so the increase in floor height can be suppressed.

In the second embodiment, an air conditioner 71 that blows air into the clean room is provided on the ceiling panel 12, and an exhaust port 72 is provided in the center of the left and right of the top surface 121 of the recessed portion 12A. The exhaust port 72 is located above the upper ceiling transport rail 2. As a result, air E blown out from the air conditioner 71 flows toward the exhaust port 72, so that dust F generated when the storage section 2A travels on the ceiling transport rail 2 is attracted into the ceiling chamber 16, preventing contamination of the clean room and maintaining the cleanliness of the clean room.
In this embodiment, the exhaust port 72 is attached to the upper part of the ceiling transport rail 2, but is not limited to this position and can also be disposed, for example, on the side surface of the recessed portion 12A.

The above describes an embodiment of the in-building ceiling transport system and the in-building ceiling transport rail installation method according to the present invention, but the present invention is not limited to the above embodiment and can be modified as appropriate without departing from the spirit of the invention.

For example, in this embodiment, a suspended ceiling 10 is provided on the top surface of the structure, and the side bars 3 are supported by the base frame 11 of the suspended ceiling 10, but the configuration is not limited to a suspended ceiling 10. For example, the side bars 3 may be provided directly on the top surface of the structure.

In addition, in this embodiment, the unit frame 4 is placed on the upper side of the multiple side bars 3 and is movable in the first direction X, the second direction Y, and the up-down direction Z, but the unit frame 4 is not limited to being provided on the upper side of the side bars 3. For example, the unit frame 4 may be provided on the lower side of the side bars 3 and guided along the lower surface of the side bars 3, allowing it to move in the first direction X and the second direction.

In addition, in this embodiment, the height adjustment method in the up-down direction Z of the unit frame 4 (transport rail unit 40) is performed using the up-down lifting member 43 provided between the unit frame 4 and the ceiling transport rail 2, but the height adjustment method is not limited to this type of up-down lifting member 43. For example, the height of the side bar 3 itself may be adjusted by adjusting the bolt fixing position of the hanging bolt 15 that suspends the side bar 3 from the base frame 11.

In addition, in this embodiment, the unit frame 4 is configured to be frame-shaped within a horizontal plane, but the size, shape, and other configurations of the unit frame 4 are not particularly limited and can be set appropriately in accordance with the shape, etc., of the ceiling conveying rail 2.

Furthermore, in this embodiment, when installing the transport rail unit 40 on the side bar 3, the transport rail unit 40 is loaded onto the transport cart 5 and driven along the floor, and then placed below the side bar 3, and the unit frame 4 of the transport rail unit 40 is placed on the side bar 3 using the aerial work vehicle 6, but this is not limited to using the transport cart 5. Also, instead of using the aerial work vehicle 6, scaffolding may be installed for construction.

In addition, the length of the ceiling transport rail 2, the number of side bars 3, their shape, spacing, etc. can be changed as appropriate.

In addition, the components in the above-described embodiments may be replaced with well-known components as appropriate without departing from the spirit of the present invention.
