Description

  The present invention relates to a building in which an outer wall panel is fixed to a building frame, and a construction method suitable for constructing the building.

  When installing an outer wall panel in a building with a frame structure, the outer wall panel is suspended by a crane and moved from the outdoor side to a predetermined attachment position. In general, a scaffold is built around the building, an operator guides the outer wall panel from the scaffold to a predetermined mounting position, and the outer wall panel is fixed by a nail or the like from the outdoor side.

  However, in an environment where the crane cannot enter to the vicinity of the construction site, it is impossible to suspend the outer wall panel and move it. In addition, in a narrow site where the interval between adjacent buildings is small, even if the crane enters the vicinity of the construction site, the outer wall panel may collide with the adjacent building when the outer wall panel is suspended and moved. Furthermore, since there is no space for installing a scaffold around the building, it is impossible to guide the outer wall panel from the outdoor side or to fix the outer wall panel.

Therefore, as a technique for solving the above problems, a technique has been proposed in which an outer wall panel is attached from the indoor side of a building (see, for example, Patent Document 1).
JP-A-7-238609

  However, the above-described technique for attaching the outer wall panel from the indoor side is very difficult to handle indoors because the outer wall panel is heavy.

  An object of the present invention is to provide a building and a construction method that can be easily routed when installing an outer wall panel from the indoor side.

  In order to solve the above-mentioned problem, the building of the first invention is a building in which an outer wall panel is installed on the outer periphery of the building, and supports the outer wall panel by hanging and supporting the outer wall panel along the outer periphery of the building. The outer peripheral guide rail is provided with a guide portion for guiding the outer wall panel from the indoor side to the outer peripheral guide rail.

  According to the first invention, by guiding the outer wall panel from the indoor side to the outer peripheral guide rail through the guide portion, the outer wall panel can be supported by being suspended from the outer peripheral guide rail. It can be guided along the outer periphery of the building in a suspended state.

  Thereby, when installing the outer wall panel which is a heavy article in the predetermined position from the indoor side of a building, handling can be made easy. Therefore, the outer wall panel can be easily installed at the predetermined position even in a narrow site where the interval between adjacent buildings is difficult to hang with the crane and move to the predetermined position.

  In the building of the second invention, the outer wall panel is provided with a hanger suspended from the outer peripheral guide rail, and the hanger adjusts the height position of the outer wall panel with respect to the outer peripheral guide rail. An adjusting means is provided.

  According to this configuration, the outer wall panel can be suspended by suspending the suspension provided on the outer wall panel on the outer peripheral guide rail, and the height position of the outer wall panel in the suspended state with respect to the outer peripheral guide rail Can be adjusted by the hanging tool. Thereby, the outer wall panel can be suspended at an appropriate height so that the lower end of the outer wall panel does not contact the floor surface.

  A building of a third invention includes an indoor guide rail that supports the outer wall panel in a suspended manner and guides the outer wall panel from the indoor to the outer periphery of the building, and the indoor guide rail is connected to the outer periphery via the guide portion. It is installed in the position which guides the said outer wall panel to a guide rail.

  According to this configuration, the outer wall panel can be hung on the indoor guide rail first, and can be guided from the indoor to the outer periphery of the building in the suspended state, and the outer wall panel is guided to the outer peripheral guide rail via the guide portion. can do. Thereby, the operation | work which moves an outer wall panel from the indoor side of a building to a predetermined attachment position becomes still easier. Therefore, the work burden when constructing the outer wall panel from the indoor side can be further reduced.

  In the building of the fourth invention, at least the lower surface position of the indoor guide rail is installed at the same height as the lower surface position of the ceiling base material to which the ceiling board is attached, and the indoor guide rail has a plurality of ceiling base materials. It is used as a part of.

It can be used as a material. Therefore, at least the indoor guide rails (preferably each guide rail including the outer peripheral guide rails) are used not only for the installation work of the outer wall panel but also as a part of the necessary members of the building after the installation work. Effective use of rails can be achieved. Further, by using the guide rail as a ceiling base material, there is no need to remove the guide rail from the building after the outer wall panel is installed, so there is an advantage that the amount of work during the construction can be reduced accordingly.

  The building of the fifth invention is characterized in that the outer peripheral guide rail and the indoor guide rail are fixed to a ceiling beam.

  By fixing the outer peripheral guide rail and the indoor guide rail to the ceiling beam which is a part of the building frame, the outer peripheral guide rail and the indoor guide rail can be made difficult to bend. Thereby, since the downward deflection of the outer peripheral guide rail and the indoor guide rail is suppressed even when the outer wall panel which is a heavy object is suspended, the outer wall panel can be smoothly suspended and moved stably. An outer wall panel can be installed in a building outer peripheral part in a state.

  In the building of the sixth aspect of the invention, the outer peripheral guide rail includes a portion for suspending the outer wall panel at a position lower than the position where the outer wall panel is suspended by the indoor guide rail. The outer wall panel is fixed at the outer periphery of the building in a state where the water-stopping material below the outer wall panel is compressed against the elasticity.

  Since the hanging position of the outer wall panel by the outer guide rail is lower than the hanging position of the outer wall panel by the indoor guide rail, the outer wall panel is moved from the indoor guide rail to the outer guide rail so that the outer wall panel is below the water stop material. It can be dropped onto the top and the waterstop material can be compressed. Moreover, since the outer wall panel is disposed at a predetermined fixed position by the fall, water can be stopped at the lower end of the outer wall panel simultaneously with the placement of the outer wall panel. Therefore, it is possible to omit the water stop work that is usually performed from the outdoor side during the construction of the outer wall panel, so that not only can the work amount during the construction be reduced, but also the work from the outdoor side is impossible. Even if it exists, the water stop of the said part can be performed.

  According to a seventh aspect of the invention, there is provided an outer peripheral guide rail provided with a guide portion for supporting the outer wall panel in a suspended manner, guiding the outer wall panel along the outer periphery of the building, and further guiding the outer wall panel from the indoor side.

The outer wall panel can be suspended from the indoor side via the guide portion on the outer peripheral guide rail and moved to the attachment position along the outer peripheral guide rail. Thereby, when installing the outer wall panel which is a heavy article from the indoor side of a building in a predetermined attachment position, handling can be facilitated. Therefore, the outer wall panel can be easily installed at a predetermined position even in a narrow site where the interval between adjacent buildings is small.

  In the construction method according to an eighth aspect of the present invention, the rail installation step includes a step of installing an indoor guide rail that supports the outer wall panel while suspending the outer wall panel and guides the outer wall panel from the indoor to the outer periphery of the building. The moving step includes a step of suspending the outer wall panel on the indoor guide rail, then moving the outer wall panel to the guide portion along the indoor guide rail, and delivering the outer wall panel to the guide portion. .

  According to this configuration, an indoor guide rail is installed to support the outer wall panel in a suspended manner and guide the outer wall panel from the indoor to the outer periphery of the building. The outer wall panel is suspended from the indoor guide rail, and the outer wall panel is suspended in the suspended state. Can be moved to the guiding portion, and the outer wall panel can be transferred to the guiding portion. Therefore, the work burden when constructing the outer wall panel from the indoor side can be further reduced.

  The construction method according to a ninth aspect of the invention is characterized by further comprising a ceiling attaching step that is performed after the suspension moving step and attaches a ceiling material to the lower surface of the indoor guide rail.

  According to this configuration, the ceiling material can be attached to the lower surface of the indoor guide rail after the outer wall panel is suspended from the indoor guide rail and the outer peripheral guide rail and moved to a predetermined attachment position. Thereby, after the indoor guide rail is used as the base material of the ceiling material after being used for the installation work of the outer wall panel, it can be effectively used. Moreover, if it is this structure, since it becomes unnecessary to remove an indoor guide rail from a building after the installation construction of an outer wall panel, the reduction of the work amount at the time of construction can be anticipated.

  In the present embodiment, the height position of the upper surface position of the intermediate horizontal portion 57 c of the outer peripheral guide rail 57 and the upper surface position of the support horizontal portion 58 a of the indoor guide rail 58 are the same. The inner side surface of the upright plate portion 58 b of the indoor guide rail 58 is set on the inner side of the end portion in the width direction of the guide port 59. Therefore, the suspension 60a can be delivered by sliding the support 60 from the support horizontal portion 58a of the indoor guide rail 58 to the intermediate horizontal portion 57c of the outer peripheral guide rail 57 via the guide port 59. The rail portion 56 can be slid to the outer peripheral guide rail portion 55.

  A pair of suspender weld nuts 61 screwed to the suspender 60 are fixed at a predetermined interval in the width direction of the outer wall panels 20 and 30. Specifically, the pair of hoist nuts 61 for lifting implements is set such that the distance between the centers thereof is equal to the distance between the center lines along the longitudinal direction of the pair of slits S3 formed in the rail portion 50. Yes. Accordingly, since the pair of suspensions 60 attached by screwing to the pair of suspension-use weld nuts 61 are also attached at the same interval as the above-described interval, the pair of suspensions 60 is connected to the pair of indoors. The outer wall panels 20 and 30 can be suspended by being suspended from the guide rail portion 56.

  On the ceiling beams 16, 17, etc., a field edge receiver 67 as a ceiling base material is fixed by a plurality of nails or the like at a predetermined interval in parallel with the indoor guide rail portion 56. In the present embodiment, the thickness of the indoor guide rail portion 56 is equal to the thickness of the field edge receiver 67. Therefore, the lower surface of the indoor guide rail portion 56 has the same height as the lower surface of the field edge receiver 67. Further, a plurality of ceiling field edges 68 as a ceiling base material are fixed to the lower surfaces of the indoor guide rail portion 56 and the field edge receiver 67 with nails or the like at a predetermined interval in a direction orthogonal to the field edge receiver 67. Yes. The ceiling material 24 is fixed to the lower surfaces of the ceiling field edges 68.

  Next, the construction procedure of the building 10 configured as described above will be described with reference to FIG. 7, focusing on the construction procedures of the lower floor outer wall panel 20 and the upper floor outer wall panel 30.

  First, a lightweight steel frame including beams such as a lower-floor ceiling beam 16 and an upper-floor ceiling beam 17, a lower-floor column, and an upper-floor column is assembled on the top end of the foundation 11 in order from the foundation 11 side. Build a tuple structure. Then, for this frame structure, in the first floor portion 12, the floor surface base material 22 is laid on the foundation 11, and in the second floor portion 13, the floor joists 19 are installed on the lower floor ceiling beams 16 and then the floor. A floor surface base material 22 is laid on the joists 19.

  Next, installation of the lower floor outer wall panel 20 and the upper floor outer wall panel 30 is started.

  First, the lower-floor outer wall panel 20 is unloaded into the building 10 by a tow truck or the like. Then, as shown in FIG. 7A, the lower floor outer wall panel 20 is laid on the floor surface with its outer wall surface facing upward, and in this state the shutter device 25 is placed on the outer wall surface of the lower floor outer wall panel 20. It is attached to a predetermined position by a fixing means such as a bolt. Further, the hanging tool 60 is attached to the lower floor outer wall panel 20 by being screwed into a lifting nut weld nut 61 fixed to the upper frame portion 28 b of the lower floor outer wall panel 20. At this time, by adjusting the amount of tightening of the lifting device 60 so that the lower floor outer wall panel 20 can be suspended at an appropriate height position, the adjustment of the projecting dimension with respect to the upper end of the lower floor outer wall panel 20 of the lifting device 60 is also adjusted. Do it. The panel upper fixing plate 37 is temporarily fixed by bolts 38 and nuts 39 at this stage.

  Next, each outer periphery guide rail 57 is fixed to the lower surface of the outer periphery lower floor ceiling beam 16a with a bolt, and the outer periphery guide rail part 55 is constructed. Then, each indoor guide rail 58 is fixed to the lower surface of the indoor lower floor ceiling beam 16b by bolt welding or the like, and the indoor guide rail portion 56 is constructed. Thereby, the rail part 50 is constructed | assembled.

  Next, as shown in FIG. 7B, the lower-floor outer wall panel 20 is raised upright so that the lifting tool 60 faces upward and the outer wall surface faces the outdoor side. Then, the hanging portion 60 a of the hanging tool 60 is inserted into the inner area of the indoor guide rail portion 56 from the opening at the indoor side end portion of the indoor guide rail portion 56. Specifically, the bolt part of the hanging tool 60 is inserted into the slit S3 and the hanging part 60a is placed on the support horizontal part 58a of the indoor guide rail 58. As a result, the lower-floor outer wall panel 20 is suspended from the indoor guide rail portion 56. In addition, since the lower-floor outer wall panel 20 is suspended by a pair of suspension tools 60, even if it is in the suspended state, it is suspended in a stable state without rotating.

  After the lower-floor outer wall panel 20 is suspended, the lower end of the lower-floor outer wall panel 20 is supported by a transport carriage 62 that constitutes support means. The transport carriage 62 includes support height adjusting means using a quadrilateral link mechanism, whereby the height position of the lower floor outer wall panel 20 supported by the transport carriage 62 can be adjusted. Yes. When the lower floor outer wall panel 20 is supported by the transport carriage 62, the adjustment height is used to adjust the support height of the lower floor outer wall panel 20 to an appropriate position.

  Next, the lower floor outer wall panel 20 is moved to the outdoor side, that is, to the outer peripheral guide rail portion 55 side, while the lifting tool 60 is slid along the indoor guide rail portion 56. When moving, the lower floor outer wall panel 20 is moved while being pushed by the transport carriage 62. The lower floor outer wall panel 20 may be moved, for example, by connecting a rope to the lower floor outer wall panel 20 and pulling the rope. When the lower floor outer wall panel 20 is moved to the outdoor side, the hanging portion 60a of the hanging tool 60 eventually passes through the indoor guide rail portion 56 and enters the inner region of the outer peripheral guide rail portion 55 from the guide port 59 as it passes. Then, when the lifting device 60 enters the inner region of the outer peripheral guide rail portion 55, the transport carriage 62 reaches the outdoor side end portion of the floor surface, and here, the transport cart is started from the lower end portion of the lower floor outer wall panel 20. 62 is extracted. When the lower floor outer wall panel 20 is further moved to the outdoor side, the hanging portion 60a falls from the intermediate horizontal portion 57c to the support horizontal portion 57a, and accordingly, the lower floor outer wall panel 20 also falls downward.

  After the lower floor outer wall panel 20 falls, the lower floor outer wall panel 20 is moved along the outer peripheral guide rail portion 55 to a predetermined mounting position. After the movement, the lower floor outer wall panel 20 is tilted by pushing the lower part of the lower floor outer wall panel 20 to the outdoor side, and the lower floor outer wall lower panel 31 is attached to the panel lower fixing plate 29 in this tilted state. A water blocking material 34 is placed at a predetermined position on the upper end of the lower panel 31. Then, the lower-floor outer wall panel 20 in an inclined state is lifted up slightly while standing upright, and then the lower-floor outer wall panel 20 is installed above the lower-floor outer wall lower panel 31. Thereby, the water stop material 34 is compressed and the water stop between the lower floor outer wall panel 20 and the lower floor outer wall lower panel 31 is performed.

  Next, the lower floor outer wall panel 20 is fixed. First, the lower end of the lower floor outer wall panel 20 is fixed by screwing the bolt 35 into the lower weld nut 36 provided in the lower floor lower frame 33 of the lower floor outer wall lower panel 31. Then, the bolt 38 and the nut 39 that temporarily fixed the panel upper fixing plate 37 are loosened, and the panel upper fixing plate 37 is slid upward. This slide movement range is defined by the vertical length of the insertion hole 40. By the movement, the upper end portion of the panel upper fixing plate 37 is brought into contact with the outer peripheral guide rail 57. And the panel upper part fixing plate 37 is fixed by screwing the volt | bolt 43 in the contact state to the beam lower side weld nut 41 provided in the outer periphery lower floor ceiling beam 16a. Furthermore, the panel upper fixing plate 37 is fixed to the lower floor outer wall panel 20 by fastening the bolts 38 and nuts 39 loosened in the above procedure. Thereby, the upper end part of the lower floor outer wall panel 20 is fixed. The fixing work of the lower floor outer wall panel 20 is thus completed.

  In the procedure described above, each lower-floor outer wall panel 20 is installed and fixed in order from the outside on both sides of the pair of indoor guide rail portions 56. Only the lower-floor outer wall panel 20 installed on the outdoor side of the indoor guide rail portion 56 is not installed at this stage.

  After the installation and fixing of each lower-floor outer wall panel 20 is completed, the work of installing the lower-floor outer wall panel 20 installed on the outdoor side of the pair of indoor guide rails 56 that has been left without performing the installation work is performed. Do. First, the lower floor outer wall lower panel 31 is fixed at a predetermined position, and the water stop material 34 is placed at a predetermined position at the upper end of the lower floor outer wall lower panel 31. Then, the lower floor outer wall panel 20 is guided along the indoor guide rail portion 56 to the outer peripheral guide rail portion 55 by the procedure described above, and then the lower floor outer wall panel 20 is further moved to the outdoor side as shown in FIG. Drop down by moving. Then, the lower floor outer wall panel 20 falls to a predetermined mounting position on the lower floor outer wall lower panel 31. The water stop material 34 is compressed by this fall, and water stop is performed between the lower floor outer wall panel 20 and the lower floor outer wall lower panel 31. Then, the lower floor outer wall panel 20 is fixed by the procedure described above.

  Thus, the installation and fixing of all the lower floor outer wall panels 20 are completed.

  Next, the upper floor outer wall lower panel 44 is attached. After the lower panel fixing plate 47 is attached to the upper floor outer wall lower panel 44 with bolts in advance, the bolt 49 is screwed into the beam upper weld nut 48 provided on the outer peripheral lower floor ceiling beam 16a, thereby lowering the lower panel fixing plate 47. It is fixed to the upper surface of the outer periphery lower floor ceiling beam 16a. Thereby, the upper floor outer wall lower panel 44 is fixed to the outer peripheral lower floor ceiling beam 16a. Then, a water stop cover 51 is attached to a gap formed between the outer wall plate 27 of the lower floor outer wall panel 20 and the upper floor lower outer wall plate 45 of the upper floor outer wall lower panel 44. Thereby, the water stop between the lower floor outer wall panel 20 and the upper floor outer wall lower panel 44 is made.

  Thus, the installation work of the lower-floor outer wall panel 20 and the outer wall panels in the periphery thereof is completed. Further, the installation work of the upper floor outer wall panel 30 is basically the same procedure as that of the lower floor outer wall panel 20, and therefore the description thereof is omitted.

  After the installation work of the lower-floor outer wall panel 20 and the upper-floor outer wall panel 30, as shown in FIG. 7 (d), a plurality of field edge receivers 67 are arranged at predetermined intervals in parallel with the indoor guide rail portion 56, the ceiling beam 16, Secure to 17 etc. with nails. Thereafter, a plurality of ceiling field edges 68 are fixed to the field edge receiver 67 and the indoor guide rail portion 56 from below with a nail or the like in a direction orthogonal to the field edge receiver 67. Then, the ceiling material 24 is fixed to these ceiling field edges 68 from below with screws or the like. Furthermore, the building 10 is completed by performing construction work such as attaching an inner wall plate (not shown) and laying the floor finish 21.

  As mentioned above, according to this embodiment explained in full detail, the following outstanding effects are acquired.

  In this embodiment, the indoor ceiling beams 16b and 17b are provided with a pair of indoor guide rail portions 56, and the outer peripheral ceiling beams 16a and 17a are provided with outer peripheral guide rail portions 55, respectively. Arranged in accordance with the guide port 59 provided in the portion 55. And the suspension tool 60 suspended from the outer periphery guide rail part 55 and the indoor guide rail part 56 was attached to the back surface side of the upper end part of the outer wall panels 20 and 30. Thereby, the outer wall panels 20 and 30 can be guided from the indoor side of the building to the outdoor side in a state where the outer wall panels 20 and 30 are suspended from the indoor guide rail portion 56. And since the outer wall panels 20 and 30 can be moved from the indoor guide rail part 56 to the outer periphery guide rail part 55 via the guide port 59, the outer wall panels 20 and 30 can be installed in a predetermined attachment position. Thereby, when installing the outer wall panels 20 and 30 which are heavy articles in the predetermined position from the indoor side of a building, handling becomes easy. Therefore, the outer wall panels 20 and 30 can be easily attached and constructed even in a small site where the interval between adjacent buildings is small. There is also an advantage that an external scaffold can be omitted.

  In the present embodiment, since the thickness of the indoor guide rail portion 56, that is, the thickness of the indoor guide rail 58 is the same as the thickness of the field edge receiver 67, the lower surface of the indoor guide rail 58 is It is the same height as the bottom surface. Therefore, the indoor guide rail 58 can be used as a ceiling base material for fixing the ceiling field edge 68 together with the field edge receiver 67. Thereby, the indoor guide rail 58 can be used not only for the installation work of the outer wall panel but also as a part of the building 10 after the installation work, so that the indoor guide rail 58 can be effectively used. it can. Further, if the indoor guide rail 58 is used as a ceiling base material, it is not necessary to remove the indoor guide rail 58 from the building 10 after the outer wall panel is installed, so that the amount of work during the construction can be reduced accordingly.

  In the present embodiment, the shutter device 25 is attached to the outer wall surfaces of the outer wall panels 20 and 30 before the outer wall panels 20 and 30 are attached. Thereby, according to this structure, attachment of the shutter apparatus 25 normally performed from the outdoor side after installation construction of the outer wall panels 20 and 30 can be performed indoors before installation construction of the outer wall panels 20 and 30. Accordingly, the shutter device 25 can be attached to the outer wall panels 20 and 30 even in a small site where the shutter device 25 cannot be attached to the outer wall panels 20 and 30 from the outdoor side because a scaffold cannot be assembled conventionally. Become.

  In the present embodiment, both the outer peripheral guide rail 57 and the indoor guide rail 58 are fixed to the ceiling beams 16 and 17 having high rigidity, so that even if the outer wall panels 20 and 30 that are heavy objects are suspended, it is difficult to bend. . Therefore, when the outer wall panels 20 and 30 are suspended, the outer peripheral guide rails 57 or the indoor guide rails 58 are bent downward so that the lower ends of the outer wall panels 20 and 30 come into contact with the floor surface and the outer wall panels 20 and 30 are moved. The risk of being unable to move is reduced.

  The hanger 60 that suspends the outer wall panels 20, 30 is attached to the outer wall panels 20, 30 by being screwed to the hanger weld nut 61. The hanging height position of the panels 20 and 30 can be adjusted. Thus, when the outer wall panels 20 and 30 are moved in a suspended state with respect to the rail portion 50, the upper end portion and the lower end portion of the outer wall panels 20 and 30 are not in contact with the rail portion 50 and the floor surface, respectively. The height position of the outer wall panels 20 and 30 can be adjusted to an appropriate position.

  In this embodiment, when the outer wall panels 20, 30 are suspended and moved with respect to the rail portion 50, the lower ends of the outer wall panels 20, 30 can be supported by the transport carriage 62. When the outer wall panels 20 and 30 are supported only by being suspended from the rail portion 50, the ceiling beam to which the rail portion 50 is fixed is bent downward when the weight of the outer wall panels 20 and 30 is particularly large. As a result, the lower end portions of the outer wall panels 20 and 30 may come into contact with the floor surface. However, according to this configuration, the lower end portions of the outer wall panels 20 and 30 are supported by the transport carriage 62, so that such a fear is eliminated.

  Further, since the position of the support height of the transport carriage 62 can be adjusted, the support height position of the outer wall panels 20 and 30 supported by the transport carriage 62 can be adjusted. Thereby, the support height position of the outer wall panels 20 and 30 can be adjusted to a suitable position so that the upper end part of the outer wall panels 20 and 30 may not contact the rail part 50 at the time of hanging the outer wall panels 20 and 30. .

  In this embodiment, since the support horizontal part 57a of the outer periphery guide rail 57 is set lower than the intermediate horizontal part 57c, when the lower-floor outer wall panel 20 is moved to the outdoor side, the suspension part 60a of the lifting tool 60 becomes the intermediate horizontal part. It falls to the support horizontal part 57a from the part 57c. Then, with this fall, the lower floor outer wall panel 20 falls above the lower floor outer wall lower panel 31 provided in advance, and compresses the water stop material 34 placed in advance at a predetermined position on the upper end of the lower floor outer wall lower panel 31. To do. Thereby, the water stop between the lower floor outer wall panel 20 and the lower floor outer wall lower panel 31 can be performed simultaneously with the installation of the lower floor outer wall panel 20 at a predetermined position. Therefore, since it is not necessary to perform a water stop work for the part at the time of construction, a reduction in work amount can be expected. Moreover, although description is abbreviate | omitted about the upper-floor outer wall panel 30, since it is the structure similar to the lower-floor outer wall panel 20, water stop can be performed simultaneously with installation also about the upper-floor outer wall panel 30. FIG.

  The present invention is not limited to the description of the above embodiment, and may be implemented as follows, for example.

  In the above embodiment, a pair of indoor guide rail portions 56 are provided, but the number of indoor guide rail portions 56 may be one. In this case, the hanger 60 is preferably attached to the approximate center in the width direction of the upper end portions of the outer wall panels 20 and 30. By doing so, the outer wall panels 20 and 30 can be suspended in a stable upright state.

  In the above embodiment, when the outer wall panels 20 and 30 are suspended and moved with respect to the rail portion 50, the lower end portion of the outer wall panels 20 and 30 is supported by the transport carriage 62. However, the transport carriage 62 is used. You don't have to.

  In the above embodiment, the shutter device 25 is attached to the outer wall surface of the lower floor outer wall panel 20 indoors before the lower floor outer wall panel 20 is attached. However, the exterior member such as a surface lattice is not limited to the shutter device 25. It may be installed indoors. In general, the exterior member cannot be attached unless the scaffold is assembled. Therefore, the exterior member cannot be attached after the installation of the outer wall panels 20 and 30 in a narrow area where the scaffold cannot be assembled. If it is the configuration, it can be attached.

  In the above-described embodiment, the outer peripheral guide rail portion 55 and the indoor guide rail portion 56 are each configured by the plurality of outer peripheral guide rails 57 and the indoor guide rail 58, but may each be configured by one guide rail.

  In the above embodiment, after installing the outer wall panels 20 and 30, the indoor guide rail portion 56 is used as a ceiling base material. However, not only the indoor guide rail portion 56 but also the outer peripheral guide rail portion 55 is used as a ceiling base material. Also good.

  Moreover, it is good also as a structure which does not use the indoor guide rail part 56 and the outer periphery guide rail part 55 as a ceiling base material. However, in this case, after the outer wall panels 20 and 30 are attached and installed, an operation of removing the indoor guide rail portion 56 and the outer peripheral guide rail portion 55 is performed, so that the amount of work during the construction may increase. Therefore, in view of this point, it is desirable that the indoor guide rail portion 56 and the outer peripheral guide rail portion 55 be configured to be used as a ceiling base material. However, if the indoor guide rail portion 56 and the outer peripheral guide rail portion 55 are removed and reused in another building, it may be configured not to be used as a ceiling base material.
