[0008] [Embodiment] An embodiment of a curtain wall installation method will be described. The curtain wall installation method is a method for installing a curtain wall. In particular, the curtain wall installation method is a method for installing a curtain wall temporarily placed on a floor above the installation floor to the installation floor. Hereinafter, a direction that intersects with the vertical direction Z and runs along the exterior wall of the building will be referred to as a width direction X. In other words, the width direction X corresponds to an example of the width direction of a building. A direction that intersects with the vertical direction Z and the width direction X will be referred to as a depth direction Y. The depth direction Y includes a direction toward the inside of the building and a direction toward the outside of the building.

[0009] <Curtain wall mounting configuration> As shown in FIG. 1, the curtain wall 10 is a member that is attached to a building 99 to form a part of the exterior wall of the building 99. The building 99 is provided with an installation floor 90, a first upper floor 91 which is one floor above the installation floor 90, and a second upper floor 92 which is one floor above the first upper floor 91. The first upper floor 91 corresponds to an example of an upper floor. Hereinafter, the floor to which the curtain wall 10 is to be attached will be described as the installation floor 90. FIG. 1 is also a diagram showing a state in which the curtain wall 10 suspended from the first upper floor 91 is inverted.

[0010] A slide rail 93 is provided on the frame of each floor of the building 99. As a specific example, the slide rail 93 is provided on the frame 91A of the first upper floor 91. More specifically, the slide rail 93 is attached to a floor portion constituting the frame 91A of the first upper floor 91. The slide rail 93 may be attached to a base plate constituting the frame 91A of the first upper floor 91. The slide rail 93 is provided on the outer edge portion of the building 99 in the depth direction Y.

[0011] The slide rail 93 is a rail extending in the width direction X. In particular, the slide rail 93 is a rail extending in the width direction X across the mounting regions of multiple curtain walls 10. The slide rail 93 may be a rail whose length in the width direction X is a part of the total width of the building 99. The slide rail 93 is a member for sliding the conveying device 30, which will be described later. The slide rail 93 is also used as a member for fastening the curtain walls 10.

[0012] The curtain wall 10 has an inner wall surface 11 and an outer wall surface 12. The inner wall surface 11 is a surface that faces the inside of the building 99 when the curtain wall 10 is attached to the building 99. The outer wall surface 12 is a surface that faces the outside of the building 99 when the curtain wall 10 is attached to the building 99. The curtain wall 10 may have a member that protrudes from the outer wall surface 12. The member that protrudes from the outer wall surface 12 may be, for example, a louver.

[0013] The curtain wall 10 has an upper end 13 and a lower end 14. The upper end 13 is a portion that is located at the upper end of the curtain wall 10 when the curtain wall 10 is attached to the building 99. The lower end 14 is a portion that is located at the lower end of the curtain wall 10 when the curtain wall 10 is attached to the building 99.

[0014] The curtain wall 10 is attached to the skeleton of the building 99 by a unit construction method, but is not limited to this, and may be attached to the skeleton of the building 99 by, for example, a semi-unit construction method or a knock-down construction method. The curtain wall 10 is a full-floor height unit, but is not limited to this, and may be, for example, a horizontally connected unit.

[0015] Before being attached to the framework, the curtain wall 10 is temporarily placed on the first upper floor 91. The curtain wall 10 may be temporarily placed on the first upper floor 91 in a vertically stacked state using pallets.

[0016] The curtain wall 10 temporarily placed on the first upper floor 91 is connected to the suspension device 20 described later. The curtain wall 10 may be connected to the suspension device 20 via a suspension balance 21 described later. The curtain wall 10 may be connected to the suspension device 20 after being laid flat with the exterior wall surface 12 facing upward.

[0017] The curtain wall 10 is suspended from the first upper floor 91 in a state in which it is connected to the suspension device 20. The curtain wall 10 may be suspended from the first upper floor 91 after being laid flat with the exterior wall surface 12 facing upward.

[0018] After being hung from the first upper floor 91, the curtain wall 10 is turned over so that the exterior wall surface 12 faces the outside of the building 99. The curtain wall 10 is hung from the hanging device 20 to the installation floor 90. This allows the position of the curtain wall 10 to be adjusted in the vertical direction Z.

[0019] The curtain wall 10 is temporarily placed on the installation floor 90 while being suspended from the suspension device 20. When the curtain wall 10 is temporarily placed on the installation floor 90, the lower end 14 of the curtain wall 10 suspended from the suspension device 20 abuts against the upper end 13 of the curtain wall 10 attached to the lower floor, which is one floor below the installation floor 90.

[0020] The curtain wall 10 is temporarily placed on the installation floor 90 and slid in the width direction X by a conveying device 30 described later. In particular, the curtain wall 10 is slidable in the width direction X so as to straddle the installation areas of a plurality of curtain walls 10.

[0021] The suspension device 20 is installed on the second upper floor 92. The suspension device 20 is connectable to the curtain wall 10. The suspension device 20 includes a wire connectable to the curtain wall 10. The suspension device 20 is connectable to the curtain wall 10 via a hoist 21. The suspension device 20 is capable of lifting the connected curtain wall 10. The suspension device 20 is capable of suspending the connected curtain wall 10. The suspension device 20 may be a floor crane.

[0022] <Upper end 13 and lower end 14> 2 and 3, the configuration of the upper end 13 and the lower end 14 of the curtain wall 10 will be described. Hereinafter, the curtain wall 10 attached to the installation floor 90 may be referred to as the first curtain wall 10A, and the curtain wall 10 attached to the lower floor may be referred to as the second curtain wall 10B.

[0023] As shown in FIG. 2 and FIG. 3, the upper end 13 of the curtain wall 10 has an upper surface 13A. The upper surface 13A is a surface facing upward. The upper end 13 of the curtain wall 10 has a recess 13B. The recess 13B may be provided on the inside in the depth direction Y at the upper end 13 of the curtain wall 10. The recess 13B is recessed with respect to the upper surface 13A. That is, the upper end 13 of the curtain wall 10 has a recessed shape. The recess 13B extends in the width direction X. The recess 13B is provided over the entire width of the curtain wall 10 in the width direction X. That is, the recess 13B is provided between both side ends of the curtain wall 10 in the width direction X. In this way, when multiple curtain walls 10 are arranged side by side in the width direction X, the recess 13B is provided so as to be continuous over the entire width of the multiple curtain walls 10 in the width direction X.

[0024] The lower end 14 of the curtain wall 10 has a bottom surface 14A. The bottom surface 14A is a surface facing downward. The lower end 14 of the curtain wall 10 has a convex portion 14B. The convex portion 14B may be provided on the inside in the depth direction Y at the lower end 14 of the curtain wall 10. The convex portion 14B has a convex shape that protrudes downward from the bottom surface 14A. In other words, the lower end 14 of the curtain wall 10 has a protruding shape. The convex portion 14B extends in the width direction X.

[0025] Hereinafter, a case will be described in which the lower end 14 of the first curtain wall 10A is temporarily placed on the upper end 13 of the second curtain wall 10B. In such a case, with the convex portion 14B of the first curtain wall 10A inserted into the concave portion 13B of the second curtain wall 10B, the bottom surface 14A of the first curtain wall 10A abuts against the upper surface 13A of the second curtain wall 10B.

[0026] This allows the first curtain wall 10A to slide in the width direction X while being temporarily placed on the upper end portion 13 of the second curtain wall 10B. In particular, the first curtain wall 10A is slidable in the width direction X over the upper end portion 13 of the second curtain wall 10B so as to straddle the mounting regions of the multiple curtain walls 10.

[0027] In this case, a gap 18 is formed between the convex portion 14B of the first curtain wall 10A and the concave portion 13B of the second curtain wall 10B. This allows the first curtain wall 10A to slide smoothly in the width direction X.

[0028] When the first curtain wall 10A is slid to a predetermined mounting position, the fitting member 19 fits into the gap 18. This allows the first curtain wall 10A to be mounted on the mounting floor 90 without providing an unnecessary gap between the first curtain wall 10A and the second curtain wall 10B. The fitting member 19 may be used in common for curtain walls 10 adjacent in the width direction X.

[0029] <Curtain wall transport method and fastening method> Next, a method for transporting and fastening the curtain wall 10 in the width direction X will be described with reference to Figs.

[0030] As shown in Figs. 4 and 5, when attaching the curtain wall 10 to the installation floor 90, the conveying device 30 is attached to the first upper floor 91. The conveying device 30 is attached to a slide rail 93 of the first upper floor 91 so as to be slidable in the width direction X. The conveying device 30 is slidable in the width direction X along the slide rail 93. The conveying device 30 may be movable electrically or may be manually movable by an operator. The conveying device 30 is fixed to the upper end portion 13 of the curtain wall 10 by a fixing member 39. The conveying device 30 conveys the curtain wall 10 in the width direction X.

[0031] The conveying device 30 includes a main body 31. The main body 31 includes a sliding portion 32. The sliding portion 32 is provided on the bottom surface of the main body 31. The sliding portion 32 abuts against a slide rail 93 or a structure 91A of the first upper floor 91. The main body 31 includes a slide groove 33. The slide groove 33 is provided on the bottom surface of the main body 31. The slide groove 33 extends in the width direction X. A rail portion 93A of the slide rail 93 is inserted into the slide groove 33.

[0032] The conveying device 30 includes an attachment portion 34. The attachment portion 34 is located above the main body portion 31. The attachment portion 34 is provided on the outside of the main body portion 31 in the depth direction Y. The attachment portion 34 includes an insertion hole 35. A fixing member 39 can be inserted into the insertion hole 35. With the fixing member 39 inserted into the insertion hole 35, the fixing member 39 is fixed to the upper end portion 13 of the curtain wall 10, whereby the conveying device 30 is attached to the upper end portion 13 of the curtain wall 10.

[0033] A case will be described in which the first curtain wall 10A is attached at a first position P1 as shown in Fig. 6. In this case, the first curtain wall 10A may be suspended at a fourth position P4.

[0034] The first position P1 is a position corresponding to the mounting area where the first curtain wall 10A is to be mounted. The fourth position P4 is located between the second position P2 and the third position P3. The second position P2 is an adjacent mounting area in the width direction X to the first position P1. The third position P3 is an adjacent mounting area in the width direction X to the second position P2.

[0035] The conveying device 30 slides the first curtain wall 10A from the fourth position P4 to the first position P1. That is, the conveying device 30 conveys the multiple curtain walls 10 in the width direction X so as to straddle the installation areas of the multiple curtain walls 10 in the width direction X.

[0036] In this way, when attaching the first curtain wall 10A to the first position P1, it is not necessary to suspend the first curtain wall 10A at a position close to the first position P1. Therefore, the first curtain wall 10A can be attached to the attachment area without moving the suspension device 20 in the width direction X.

[0037] 4 and 7, when the first curtain wall 10A is slid into the attachment area, it is fastened to the slide rail 93 by using the fastening member 40. The fastening member 40 is a member for fastening the first curtain wall 10A to the slide rail 93.

[0038] In detail, the fastening member 40 has a main body portion 41. The main body portion 41 has an abutment surface 42. The abutment surface 42 is provided on a bottom surface of the main body portion 41. The abutment surface 42 abuts against the slide rail 93. The main body portion 41 has an engagement groove 43. The engagement groove 43 is provided on the bottom surface of the main body portion 41. The engagement groove 43 extends in the width direction X. A rail portion 93A of the slide rail 93 engages with the engagement groove 43.

[0039] The main body 41 includes a first insertion hole 44. The fixing member 49 can be inserted into the first insertion hole 44. With the fixing member 49 inserted into the first insertion hole 44 and into the insertion hole 93B of the slide rail 93, the fixing member 49 is fixed to the main body 41, whereby the fastening member 40 is attached to the slide rail 93.

[0040] The fastening member 40 includes an attachment portion 45. The attachment portion 45 is located above the main body portion 41. The attachment portion 45 is provided on the outside of the main body portion 41 in the depth direction Y. The attachment portion 45 includes a second insertion hole 46. The second insertion hole 46 allows the fixing member 49 to be inserted therethrough. With the fixing member 49 inserted into the second insertion hole 46, the fixing member 49 is fixed to the upper end portion 13 of the curtain wall 10, whereby the fastening member 40 is attached to the upper end portion 13 of the curtain wall 10. In this manner, the curtain wall 10 is attached to the slide rail 93 via the fastening member 40.

[0041] <Curtain wall installation process> Next, the curtain wall mounting process will be described with reference to FIG. 6 and FIG. 8 to FIG. 8 and 9(A), a suspension device connecting process is performed in step S10. The suspension device connecting process is a process of connecting the curtain wall 10 on the first upper floor 91 and the suspension device 20 installed on the second upper floor 92.

[0042] Specifically, in the hanging device connecting step, the curtain wall 10 that has been temporarily placed on the first upper floor 91 is laid flat. In this case, the curtain wall 10 is laid flat so that the outer wall surface 12 faces upward.

[0043] Thereafter, the suspension balance 21 is connected to the upper end portion 13 of the curtain wall 10. The suspension balance 21 and the suspension device 20 are connected to each other. As a result, the curtain wall 10 is connected to the suspension device 20 via the suspension balance 21.

[0044] As shown in Fig. 8 and Fig. 9(B), in step S11, a hanging process is performed. The hanging process is a process of hanging the curtain wall 10 from the first upper floor 91. The hanging process is a process of hanging the curtain wall 10 from the first upper floor 91 in a state in which the outer wall surface 12 of the curtain wall 10 faces upward.

[0045] Specifically, in the hanging process, on the first upper floor 91, a plurality of workers support the curtain wall 10. On the second upper floor 92, the hanging device 20 hoists the curtain wall 10 by operation by the workers.

[0046] 8, in step S12, an inversion process is performed. The inversion process is a process of inverting the curtain wall 10 suspended from the first upper floor 91. In particular, the inversion process is a process of inverting the curtain wall 10 so that the outer wall surface 12 of the curtain wall 10 faces the outside of the building 99.

[0047] Specifically, on the first upper floor 91, the worker inverts the curtain wall 10 from a position in which the outer wall surface 12 of the curtain wall 10 faces the inside of the building 99 to a position in which the outer wall surface 12 of the curtain wall 10 faces the outside of the building 99. On the first upper floor 91, the worker may invert the curtain wall 10 using the hanging balance 21 or a wire (not shown) connected to the curtain wall 10, or may invert the curtain wall 10 by touching the curtain wall 10 itself.

[0048] As shown in Fig. 8 and Fig. 10(A), in step S13, a hanging process is performed. The hanging process is a process in which the hanging device 20 hangs the curtain wall 10. The hanging process is a process in which the curtain wall 10 is moved at least downward by an operator of the hanging device 20 on the second upper floor 92. This adjusts the position of the curtain wall 10 in the vertical direction Z. In the hanging process, the curtain wall 10 may be moved in the width direction X and the depth direction Y by an operator of the hanging device 20 on the second upper floor 92.

[0049] As shown in Fig. 8 and Fig. 10(B), a temporary placement process is performed in step S14. The temporary placement process is a process of temporarily placing the lower end 14 of the curtain wall 10 suspended by the suspension device 20 on the installation floor 90. More specifically, on the installation floor 90, a worker inserts the convex portion 14B of the first curtain wall 10A into the concave portion 13B of the second curtain wall 10B. This allows the worker to temporarily place the lower end 14 of the first curtain wall 10A on the upper end 13 of the second curtain wall 10B on the installation floor 90.

[0050] In step S15, a conveying device installation process is performed. The conveying device installation process is a process of installing the conveying device 30 on the slide rail 93 on the first upper floor 91. The conveying device installation process is a process of attaching the conveying device 30 to the upper end portion 13 of the curtain wall 10 temporarily placed on the installation floor 90.

[0051] In step S16, a suspension detachment process is performed. The suspension detachment process is a process of removing the suspension balance 21 from the curtain wall 10, thereby removing the suspension device 20 from the curtain wall 10.

[0052] 6 and 8, a conveying process is performed in step S17. The conveying process is a process in which the conveying device 30 conveys the curtain wall 10 in the width direction X. In particular, the conveying process is a process in which the conveying device 30 conveys the curtain wall 10 to the installation position so as to straddle the installation areas of the multiple curtain walls 10 in the width direction X.

[0053] As a specific example, when the curtain wall 10 is temporarily placed at the fourth position P4, the conveying device 30 slides the curtain wall 10 in the width direction X to the first position P1, which is the mounting position of the curtain wall 10.

[0054] In step S18, an installation process is performed. The installation process is a process of installing the curtain wall 10 on the installation floor 90. In particular, the installation process is a process of installing the curtain wall 10 transported by the transport device 30 on the installation floor 90. In detail, on the installation floor 90, a worker uses the fastening members 40 to fix the curtain wall 10, which has been slid to the installation position, to the framework 91A of the first upper floor 91 via the slide rail 93.

[0055] In step S19, a conveying / removing process is performed. The conveying / removing process is a process of removing the conveying device 30 from the curtain wall 10 by removing the fixing members 39 from the curtain wall 10. The conveying / removing process is a process of removing the conveying device 30 from the slide rail 93.

[0056] In step S20, a fitting process is performed. The fitting process is a process in which a worker fits the fitting member 19 into the gap 18 on the installation floor 90. In detail, the fitting process is a process in which the worker fits the fitting member 19 into the gap 18 between the first curtain wall 10A and the second curtain wall 10B on the installation floor 90.

[0057] <Actions and Effects of the Embodiments> The operation and effects of the embodiment will be described. (1) The lower end 14 of the first curtain wall 10A is temporarily placed on the installation floor 90. The transport device 30 installed on the slide rail 93 on the first upper floor 91 is attached to the upper end 13 of the first curtain wall 10A. The transport device 30 transports the first curtain wall 10A to a transport position along the slide rail 93 so as to straddle the installation areas of the multiple curtain walls 10 in the width direction X. The first curtain wall 10A transported by the transport device 30 is attached to the installation floor 90. Therefore, the first curtain wall 10A can be transported to the installation position without moving the suspension device 20. This can shorten the work time involved in moving the suspension device 20. In addition, even if an obstacle such as a pillar is provided on the second upper floor 92, the first curtain wall 10A can be transported to the installation position as long as the suspension device 20 can be placed while avoiding the obstacle. Furthermore, the movement of the curtain wall 10 in the width direction X becomes easy. This can reduce the workload of each worker and can also reduce the number of workers. This improves the workability of installing the curtain wall 10. In addition, it reduces the chances of workers having to work near the exterior walls of the building 99. This improves the safety of workers.

[0058] (2) On the installation floor 90, the lower end 14 of the first curtain wall 10A suspended by the suspension device 20 is temporarily placed on the upper end 13 of the second curtain wall 10B installed on the lower floor. This eliminates the need to provide a separate member for temporarily placing the lower end 14 of the first curtain wall 10A. This allows for improved workability in installing the curtain wall 10 while reducing the number of parts.

[0059] (3) With the convex portion 14B inserted into the concave portion 13B, the first curtain wall 10A can slide in the width direction X on the upper end portion 13 of the second curtain wall 10B, so that the first curtain wall 10A can be smoothly slid in the width direction X. This improves the workability in installing the curtain wall 10.

[0060] (4) The fitting member 19 is fitted into the gap 18 between the second curtain wall 10B attached to the lower floor and the first curtain wall 10A attached to the installation floor 90. This allows the first curtain wall 10A to slide smoothly in the width direction X. On the other hand, the first curtain wall 10A can be attached to the installation floor 90 without creating a gap between the first curtain wall 10A and the second curtain wall 10B that is not intended by the designer. This improves the workability of installing the curtain wall 10.

[0061] (5) The slide rail 93 also serves as a member for fastening the curtain wall 10. Therefore, the number of parts can be reduced while improving the workability for installing the curtain wall 10.

[0062] [Example of change] This embodiment can be modified as follows: This embodiment and the following modifications can be combined with each other to the extent that there is no technical contradiction.

[0063] The slide rail 93 does not have to be used as a member for fastening the curtain wall 10 to the skeleton 91A. In other words, a member for fastening the curtain wall 10 to the skeleton 91A may be provided in addition to the slide rail 93.

[0064] The protruding portion 14B does not have to be provided across the entire width of the curtain wall 10 in the width direction X. The protruding portion 14B may be composed of a plurality of portions that are not continuous across the entire width of the curtain wall 10.

[0065] The upper end 13 of the curtain wall 10 may have a convex portion instead of the concave portion 13B, and the lower end 14 of the curtain wall 10 may have a concave portion instead of the convex portion 14B. In other words, one of the combinations of the upper end 13 and the lower end 14 of the curtain wall may have a convex portion and the other may have a concave portion.

[0066] The first curtain wall 10A is not limited to being temporarily placed on the second curtain wall 10B, and may be temporarily placed, for example, on the mounting floor 90. In this case, in order to slide the first curtain wall 10A in the width direction X, an engagement rail that engages with the lower end portion 14 of the first curtain wall 10A may be provided on the mounting floor 90.

[0067] The transport device 30 may be remotely operable by an operator. The transport process may be performed by the operator remotely operating the transport device 30. The suspension device 20 does not have to be arranged on the second upper floor 92. As a specific example, the suspension device 20 may be arranged on a third upper floor which is a floor higher than the second upper floor 92. The suspension device 20 may be arranged on the first upper floor 91.

[0068] The term "at least any" as used herein means one or more of the desired options. As an example, the term "at least any" as used herein means only one option or both options if the number of options is two.
