Description

The present invention relates to a panel frame unit and a method for transporting and installing the panel frame unit.

In the construction of walls such as outer walls, boundary walls, and partition walls that make up a steel-framed building with two or more floors, a steel frame consisting of steel columns and beams is constructed on the foundation, and then the walls are constructed. The wall is constructed by sequentially attaching a plurality of vertical furring strips and horizontal furring strips to the steel frame frame, and attaching wall panels such as outer wall panels to these furring strips. At this time, since it takes time and effort to attach the vertical furring strip and the horizontal furring strip one by one, the method of integrating the vertical furring strip and the horizontal furring strip in advance by the groundwork and suspending and transporting them to the mounting position is applied. There is. In this way, by integrating multiple furring strips with the groundwork, construction work can be saved to some extent, but the furring strips are wire rods and are transported by truck from the factory, so which wire rod is installed in which place. It takes time and effort to identify and sort the wire rod installation location, and it also takes time and effort to lay the groundwork at the site, so it cannot be expected that the construction work will be significantly eliminated.

Therefore, at the factory, the vertical furring strip and the horizontal furring strip are assembled in advance to manufacture a panel frame (so-called furring strip panelization), and the manufactured panel frame is transported by truck to the site and then attached to the steel frame frame at the site. Construction is applied. By the way, there is a limit to the size of a panel frame that can be manufactured in a factory, and one of the size setting factors is whether or not it can be loaded on a truck (that is, the maximum size that can be loaded on a truck). Therefore, in a steel-framed building with two or more floors, it is generally impossible to manufacture a panel frame that spans multiple floors at a factory and transport it by truck. Therefore, the panel frames corresponding to each floor are individually manufactured. After being manufactured, loaded on a truck, and transported to the site, the corresponding panel frames are sequentially attached to each floor. Therefore, when mounting the panel frame in the field, the order of mounting the panel frame is generated for each layer. Also, when loading multiple panel frames on a truck in a factory, the multiple panel frames are not loaded in consideration of the installation order of the panel frames (installation order from the lower floors such as the first floor and the second floor). Therefore, there is a problem that the work of changing the order of mounting the panel frames to be loaded and unloaded at the site is required.

From the above, although a certain amount of construction work can be expected to be eliminated by manufacturing the panel frame at the factory, transporting it to the site, and installing it at the site, when constructing the walls of a building with two or more floors, it is necessary to go to the site. Further improvements in transportability and on-site workability are desired.

Here, a building connecting panel capable of improving and simplifying building work, improving efficiency of transportation work, and saving space, and a building method using the same are proposed. This architectural connecting panel is provided with a ceiling panel, a middle panel, and a floor panel horizontally, each panel is connected in a direction orthogonal to the wall panel, and the wall panel has a joint portion in a vertical frame portion. The joint portion has an outer joint portion and an inner joint portion constituting the vertical frame portion, a swingable hinge fixed to the outer joint portion and the inner joint portion, and an outer joint portion and an inner joint portion. It is equipped with a main bolt to be fixed. The joint portion is arranged at the joint point between the wall panel and each of the other panels and at the half point of the wall panel so that the wall panel can be folded freely, and the main bolt is in the same direction as the swing direction of the hinge. Moreover, it is inserted in a direction orthogonal to the vertical frame portion of the wall panel (see, for example, Patent Document 1).

Japanese Unexamined Patent Publication No. 2000-54496

The architectural connecting panel described in Patent Document 1 is composed of two upper and lower panels via bendable joints for the wall panels (boundary wall panel and bearing wall panel) installed on each floor. It can be said that there is a problem in terms of structural stability of the wall due to the bendable joint existing in the middle of the wall on each floor.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a panel frame unit having excellent transportability and workability and high structural stability, and a method for transporting and installing the panel frame unit.

In order to achieve the above object, one aspect of the panel frame unit according to the present invention is
It is a panel frame unit that constitutes the wall of a building on the second floor or higher.
The ends of a plurality of panel frames having a corresponding floor height and having a vertical furring strip and a horizontal furring strip are rotatably connected to each other via a hinge.
Each of the panel frames is characterized in that it can form a folding posture folded through the hinge and an unfolding posture developed through the hinge.

According to this aspect, in a building having two or more floors, the ends of a plurality of panel frames having the corresponding floor heights are rotatably connected to each other via a hinge, so that each panel is rotatably connected during transportation. Since the frame can be loaded on the truck in the folded posture by folding it through the hinge and transported to the site, even if the panel frame unit has a length that cannot be loaded on the truck in the deployed posture, it can be loaded at the time of loading. Since it can be loaded in a folded posture with a length that allows it to be loaded, excellent transportability is achieved. Furthermore, after being transported to the site, by lifting one end of the panel frame unit with a heavy machine, the panel frame unit in the folded posture becomes the unfolded posture via the hinge, and each panel frame is in the corresponding floor. By arranging them in the above, each panel frame can be efficiently installed on the corresponding floor, and excellent workability is achieved. Furthermore, since each panel frame has a corresponding floor height, the upper panel frame and the lower panel frame, which are interconnected via hinges, have a trunk difference (beam) between floors. Since it can be firmly fixed and there is no bendable joint as described in Patent Document 1 at an intermediate position of the panel frame, high structural stability is achieved.

Here, the form of the panel frame unit having the floor height corresponding to each panel frame includes various forms, for example, in a two-story building, the first floor corresponding to each of the two panel frames. It has a second-floor height, and in a three-story building, each of the three panel frames has a corresponding first- to third-floor height, or the first and second floors of the third floor. A form having two panel frames having each floor height, a form having two panel frames having each floor height of the second floor and the third floor of the third floor, and the like are included. In this way, although some buildings with three or more floors do not have panel frames corresponding to all floors, from the viewpoint of workability, there are forms that have panel frames corresponding to all floors. preferable. Further, in the present specification, the "floor height" means, for example, the height between the body difference of the lower floor and the body difference of the upper floor (the height between the foundation and the body difference near the ceiling on the first floor). Including). Therefore, the hinge connecting the upper and lower panel frames is located on the side of the body difference, and the upper and lower panel frames via the hinge are stably fixed to the body difference.

Further, in another aspect of the panel frame unit according to the present invention, the hinges are attached to the intermediate positions of the end faces facing each other in the unfolded posture in the adjacent panel frames.
The hinge is a biaxial hinge having two rotating shafts attached to each of the end faces and a connecting plate rotatably attached to the two rotating shafts. It is characterized by.

According to this aspect, the hinge connecting the panel frames is connected to the two rotation shafts attached to the end faces of the respective panel frames and the connection rotatably attached to the two rotation shafts. By having a biaxial hinge having a plate, it is possible to form a folded posture of both panel frames even if the hinge is not provided at a position protruding outside the wide surface of the panel frame. By arranging the rotation axis of the hinge outside the wide surface of the panel frames connected to each other, the wide surfaces of the adjacent panel frames can be overlapped with each other without interfering with the rotation axis. can. However, if the rotation shaft is arranged on the outside of the wide surface in this way, when the outer wall surface material, the waterproof material (waterproof sheet, waterproof panel), etc. are attached along the wide surface of the panel frame, these will be used. It will interfere with the rotating shaft of the hinge. Therefore, as in this embodiment, a biaxial hinge is provided at an intermediate position of the end surface of the adjacent panel frame (a position where the rotation axis does not project to the outside of the wide surface of the panel frame), so that the third floor or higher Even in a building, it is possible to attach an outer wall surface material, a waterproof material, or the like to the panel frame unit without interfering with the rotating shaft.

Further, in another aspect of the panel frame unit according to the present invention, in one of the two adjacent panel frames, the part of the panel frame that comes into contact with the other panel frame when the other panel frames are overlapped is described above. A fixing member for bolting the panel frame unit to a part of the frame constituting the building is provided.
The fixing member is characterized by having a defect area in a region that interferes with the other panel frame to be overlapped, and a bolt hole in the fixing region to be fixed to the building.

According to this aspect, among the panel frames of one of the two adjacent panel frames, the other panel frames are provided at a part of the contact points when the other panel frames are overlapped with each other, and a part of the frame and a bolt are provided. Since the fixing member to be joined has a defect region in the region where it interferes with the other panel frame to be overlapped, there is no possibility that the fixing member interferes with the folding of the panel frames. For example, on the wide surface of one of the panel frames, a fixing member having a defect area (notch) in the center and bolt holes at the left and right positions thereof is provided, so that the bolt holes are part of the frame. The bolt holes of the fixing member can be aligned and bolted.

Further, another aspect of the panel frame unit according to the present invention is characterized in that the panel frame corresponding to all the floors of the building is provided.

According to this aspect, since the panel frame corresponding to all floors of the building on the second floor or higher is provided, by lifting one end of the panel frame unit with a heavy machine, the panel frame unit in the folding posture is passed through the hinge. When the unfolded posture is reached, each panel frame is arranged on all corresponding floors, resulting in a panel frame unit with even better workability.

Further, in another aspect of the panel frame unit according to the present invention, the floor height of at least one of the floors provided in the building is different from the floor height of the other floors.
Each of the plurality of panel frames has a corresponding floor height.

According to this aspect, even if the floor heights of each floor are different from each other (including the case where only one of the floors is different in the case of three or more floors), each floor is supported. Since the panel frame to be constructed has an appropriate height, the panel frame unit has excellent workability as in the case where the floor heights of all floors are the same.

Further, one aspect of the method for transporting and installing the panel frame unit according to the present invention is as follows.
It is a method of transporting and installing panel frame units that make up the walls of buildings on the second floor and above.
A panel frame unit in which the ends of a plurality of panel frames having a corresponding floor height and having a vertical furring strip and a horizontal furring strip are rotatably connected to each other via a hinge. The panel frame is transported to the site in a folded posture folded via the hinge, and the transport process.
By lifting one end of the panel frame unit with a heavy machine, the panel frame unit is in a deployed posture expanded via the hinge, and each panel frame is arranged on the corresponding floor, and the top and bottom of the hinge are placed. It is characterized by having an installation step of directly or indirectly fixing the panel frame to the difference between floors.

According to this aspect, by applying a panel frame unit in which a plurality of panel frames having floor heights of corresponding floors of a building having two or more floors are rotatably connected via a hinge, the transport process can be performed. Since each panel frame can be loaded on the truck and transported to the site in a folded posture folded via a hinge, the unfolded posture even if the panel has a length that cannot be loaded on the truck in the unfolded posture. Even if the panel frame unit has a length that cannot be loaded on a truck, it can be loaded in a folded posture having a length that can be loaded at the time of loading, so that excellent transportability is achieved. In addition, in the installation process after the panel frame unit is transported to the site, by lifting one end of the panel frame unit with a heavy machine, the panel frame unit in the folded posture becomes the unfolded posture via the hinge. By arranging and mounting the panel frames on the corresponding floors, each panel frame can be efficiently installed on the corresponding floors. Furthermore, since each panel frame has a corresponding floor height, the upper panel frame and the lower panel frame, which are interconnected via hinges, are firmly fixed to the difference between floors. Therefore, a connection structure between the frame and the panel frame unit having high structural stability is formed.

As can be understood from the above description, according to the panel frame unit of the present invention and the transport / installation method thereof, it is provided a panel frame unit having excellent transportability and workability and high structural stability, and a transport / installation method thereof. Can be done.

[Panel frame unit according to the embodiment]
First, an example of the panel frame unit according to the embodiment will be described with reference to FIGS. 1 to 4. Here, FIG. 1 is a perspective view showing a folding posture of an example of the panel frame unit according to the embodiment. Further, FIG. 2A is a diagram showing a part of the unfolded posture of the panel frame unit in which the panel frames are connected to each other by an example of a hinge, and FIG. 2B is a diagram in which one of the panel frames is folded following FIG. 2A. FIG. 2C is a diagram showing a state in which adjacent panel frames are folded, following FIG. 2B.

The panel frame unit 60 shown in FIG. 1 is a panel frame unit constituting an outer wall of a four-story steel-framed building. The panel frame unit can be applied to a building having two or more floors other than a four-story building, and can be applied to a boundary wall or a partition wall in addition to the outer wall. Examples of buildings to which the panel frame unit is applied include steel-framed detached houses, distribution warehouses, and long-term care facilities (Long-Term Care Health Facility).

In FIG. 1, a plurality of hinges 40 (see FIG. 2A and the like) include a panel frame 30A corresponding to the fourth floor, a panel frame 30B corresponding to the third floor, a panel frame 30C corresponding to the second floor, and a panel frame 30D corresponding to the first floor. ) Is rotatably connected to form the panel frame unit 60.

The heights of each floor of the four-story building to be constructed are different from each other. For example, in the panel frame unit 60 of the illustrated example, the length of the panel frame 30A is t1, and the heights of the panel frames 30B and 30C. Is t2, the height of the panel frame 30D is t3, and each panel frame 30 has the height of the corresponding floor (in the illustrated example, t1> t2> t3).

The panel frame unit 60 shown in FIG. 1 exhibits a folding posture in which panel frames 30 adjacent to each other are folded via a hinge 40. Each panel frame 30 is formed by welding a plurality of vertical furring strips 10 (three in the illustrated example) and a plurality of horizontal furring strips 20 (two in the illustrated example) to each other in a rectangular frame shape. .. Both the vertical furring strip 10 and the horizontal furring strip 20 are formed of channel steel and are provided with webs 11 and 21 and upper and lower flanges 12 and 22, but are formed of other shaped steel materials such as angle steel and H-shaped steel. It may be formed by a square steel pipe.

In the transport installation method of the panel frame unit according to the embodiment described in detail below, in the transport step, the panel frame unit 60 is loaded on a truck (not shown) in the folding posture shown in FIG. 1 and transported to the construction site. ..

As shown in FIG. 2A, in the two adjacent panel frames 30, for example, one flange 22 constituting both horizontal furring strips 20 is rotatably connected to each other by a hinge 40. The hinge 40 has two blade plates 41 and a plurality of shaft cylinders 42 provided at one end of each blade plate 41. A continuous shaft cylinder is formed by fitting both shaft cylinders 42, and a hinge 40 having a rotating shaft 44 in the center is configured by inserting the rotating shaft body 43 into the continuous shaft cylinders. To.

The two panel frames 30 and the hinge 40 are connected by screwing the screws 45 into both flanges 22 through a plurality of screw holes (not shown) provided in each blade plate 41.

As shown in FIG. 2B, one panel frame 30B is rotated toward the other panel frame 30A side via the hinge 40 in the X1 direction, and further rotated, so that both are as shown in FIG. 2C. The flanges 12 of the vertical furring strips 10 of the panel frames 30A and 30B and the flanges 22 of the horizontal furring strips 20 are in contact with each other, and the respective panel frames 30A and 30B are folded via the hinge 40 to form a folding posture. To.

Here, with reference to FIG. 3, another example of the hinge and the mounting mode of the hinge to the panel frame will be described. Here, FIG. 3A is a diagram showing a part of the deployed posture of the panel frame unit in which the panel frames are connected to each other in another example of the hinge, and FIG. 3B is a diagram showing adjacent panels following FIG. 3A. It is a figure which shows the state which the frame is folded.

The hinge 40A shown in FIG. 3A has two blade plates 41 connected to both panel frames 30 and a connecting plate 46 between them. A plurality of shaft cylinders 42 are provided at one end of the two blade plates 41, and a plurality of shaft cylinders 42 are also provided at both ends of the connecting plate 46. Two shaft cylinders are formed, and the rotating shaft body 43 is inserted into each of the two continuous shaft cylinders to form a biaxial hinge 40A having two rotating shafts 44. .. Although not shown, the two hinges 40 shown in FIG. 2A are arranged side by side, and one blade plate 41 of both hinges 40 is connected to each other via a connecting plate to form a biaxial hinge. May be good.

The two blade plates 41 forming the biaxial hinge 40A are attached to the intermediate positions of the web 21 of the horizontal furring strip 20 of both panel frames 30 via a plurality of screws 45. The two rotating shafts 44 are located on the surfaces of both webs 21, and by rotating one panel frame 30A toward the other panel frame 30B in the X2 direction from the unfolded posture of FIG. 3A, FIG. 3B shows. A folding posture is formed in which the panel frames 30A and 30B shown are folded together.

The hinge 40A connecting the panel frames 30A and 30B is provided with two rotation shafts 44 and is attached to the middle position of the web 21 of the horizontal furring strip 20 of both panel frames 30. Is not provided at a position protruding outside the flange 22 of the lateral furring strip 20 of both panel frames 30 (in FIG. 2A, the hinge 40 is provided at a position protruding outside the flange 22). , It is possible to form the folding posture of both panel frames 30.

For example, the rotation shaft 44 of the hinge is arranged outside the flange 22 of the horizontal furring strip 20 of the panel frame 30 and the flange 12 of the vertical furring strip 10 connected to each other. The flanges 22 and the flanges 12 of the adjacent panel frames 30 can be overlapped with each other without interfering with each other. However, if the hinge rotation shaft 44 is arranged on the outside of the flanges 22 and 12, when the outer wall surface material, the waterproof material, or the like is attached along the flanges 22 and 12 of the panel frame 30, when the outer wall surface material, the waterproof material, or the like is attached. These will interfere with the rotating shaft 44 of the hinge. For example, in the case of a two-story building, the panel frame 30 can be rotated by arranging the panel frame 30 in a posture in which the rotation shaft 44 arranged on the outside of the flanges 22 and 12 of the panel frame 30 is directed toward the indoor side. With the flanges 22 and 12 of the panel frame 30 on which the shaft 44 does not overhang as the outdoor side, it becomes possible to attach a water blocking material or an outer wall surface material along these flanges 22 and 12, and interfere with the rotating shaft 44. It is possible to attach an outer wall material or a sheet material without any need. However, in the case of a building with three or more floors, considering the overlapping of adjacent panel frames 30, a plurality of hinges connecting the panel frames 30 are located outside the flanges 22 and 12 on both sides of the panel frame unit 60. Even if one hinge is directed to the indoor side, the other hinge will be on the outdoor side, and the rotating shaft 44 of the hinge overhanging to the outdoor side will be a waterproof material or an outer wall surface. It can be an obstacle to the installation of materials.

Therefore, as shown in the illustrated example, the biaxial hinge 40A is provided at an intermediate position of the web 21 of the adjacent panel frame 30 (a position where the rotating shaft 44 does not project to the outside of the flanges 22 and 12 of the panel frame 30). This makes it possible to attach an outer wall surface material, a waterproof material, or the like to the panel frame unit 60 without interfering with the rotating shaft 44 even in a building having three or more floors.

Next, with reference to FIG. 4, an example of the fixing member and the unfolding posture and the folding posture of one panel frame provided with the fixing member and the other panel frame will be described. Here, FIG. 4A is a diagram showing a part of the unfolded posture of one panel frame provided with an example of a fixing member and the other panel frame, and FIG. 4B shows one panel frame following FIG. 4A. It is a figure which shows the folded state, and FIG. 4C is a figure which shows the state which adjacent panel frames are folded after FIG. 4B.

In the example shown in FIG. 4, the flanges 12 of the vertical furring strips 10 of both panel frames 30A and 30B are connected to each other via a hinge 40. A fixing member 50 bolted to a fixing jig (not shown) projecting from a steel frame frame constituting a building is welded to the flange 12 of the vertical furring strip 10 of the panel frame 30A.

The fixing member 50 is provided with a notch 53 (an example of a defect region) in the center of one end of a flat steel having a rectangular view in a plan view, and bolt holes 52a are opened in the fixing pieces 52 (an example of a fixing region) on both sides of the notch 53. After that, by bending the fixing pieces 52 on both sides of the notch 53, the connecting piece 51 is connected to the flange 12, and the two fixing pieces 52 stand up in a posture orthogonal to the connecting piece 51.

From the unfolded posture shown in FIG. 4A, one panel frame 30B is rotated toward the other panel frame 30A in the X3 direction as shown in FIG. 4B, and the panel frame 30B is further rotated as shown in FIG. 4C. The flanges 12 of the vertical furring strips 10 and the flanges 22 of the horizontal furring strips 20 of both panel frames 30A and 30B are brought into contact with each other to form a folded posture. At this time, since the vertical furring strip 10 of the folded panel frame 30B can enter the notch 53 in the center of the fixing member 50, the fixing member 50 and the panel frame 30B do not interfere with each other in the folded posture. ..

[Method of transporting and installing the panel frame unit according to the embodiment]
Next, an example of a method of transporting and installing the panel frame unit according to the embodiment will be described with reference to FIGS. 1 and 5 to 10.

In the method of transporting and installing the panel frame unit, the panel frame unit 60 is manufactured at the factory, and the panel frame unit 60 is loaded on the truck in the folded posture as shown in FIG. Here, when the panel frame unit 60 in the folded posture is loaded on the truck, the panel frame 30A corresponding to the top floor is loaded at the uppermost portion of the folded posture so that the panel frame unit 60 is installed at the site. .. The panel frame unit 60 loaded on the truck is transported to the construction site (the above is the transport process).

Next, as shown in FIG. 5, among the panel frame units 60 transported to the construction site, a plurality of locations of the horizontal furring strip 20 which is one end of the panel frame 30A at the uppermost part of the folded posture (two locations in the illustrated example). ), And the wire 92 is lifted in the upper Y1 direction by a heavy machine (not shown) with one end of the wire 92 fixed to each hanging jig 91.

By lifting by the wire 92, each panel frame 30 in the folded posture is sequentially unfolded via the hinge 40 from FIG. 5 to FIG. 6 and further, and all the panel frames 30 are unfolded. As shown in 8, the unfolded posture of the panel frame unit 60 is formed.

The panel frame unit 60 in the unfolded posture suspended by heavy machinery is transferred to a predetermined position on the outer wall of the steel frame frame of the building to be constructed, and the panel frames 30A, 30B, 30C, 30D constituting the panel frame unit 60 are formed. Are aligned on the corresponding 4th, 3rd, 2nd, and 1st floors, respectively.

As shown in FIG. 9, the lower end of the panel frame 30D corresponding to the first floor is bolted to the top end of the reinforced concrete foundation 71 via a shaped steel material such as angle steel. Further, as shown in FIG. 10, the hinge 40 connecting the panel frame 30D having the floor height of the first floor and the panel frame 30C corresponding to the second floor is located on the side of the trunk difference 72 between the first floor and the second floor. Aligned. The body difference 72 is formed of H-shaped steel having a web 72a and upper and lower flanges 72b and 72c, and the hinge 40 is arranged on the side of the web 72a.

Fixing jigs 81 extending in the longitudinal direction of the body difference 72 and formed of angle steel are attached to the upper surfaces and the lower surfaces of the upper and lower flanges 72b and 72c of the body difference 72, respectively.

A bolt hole (not shown) is provided below the flange 12 of the vertical furring strip 10 constituting the panel frame 30C corresponding to the second floor, and a fixing jig attached to the flange 72b above the furring strip 72. The bolt hole (not shown) provided in 81 and the bolt hole of the flange 12 are aligned, and by screwing the bolt 82, the lower part of the panel frame 30C and the body difference 72 are bolted together.

On the other hand, a bolt hole (not shown) is provided above the flange 12 of the vertical furring strip 10 constituting the panel frame 30D corresponding to the first floor, and is attached to the flange 72c below the furring strip 72. The bolt holes (not shown) provided in the fixing jig 81 and the bolt holes of the flange 12 are aligned, and by screwing the bolts 82, the upper part of the panel frame 30D and the body difference 72 are bolted together. ..

Similarly, for the trunk difference 73 between the second and third floors, the upper part of the panel frame 30C having the floor height of the second floor and the lower part of the panel frame 30B are bolted together, and the trunk between the third and fourth floors is bolted. Similarly, for the difference 74, the upper part of the panel frame 30B having the floor height of the third floor and the lower part of the panel frame 30A are bolted together. The upper part of the panel frame 30A is bolted to the eaves girder 75.

In this way, the panel frame unit 60 is firmly attached to the steel frame frame of the building by bolting the panel frame 30 corresponding to each floor to the corresponding body difference 72 to 74, the foundation 71, and the eaves girder 75. Will be. In the illustrated example, the panel frame 30 is indirectly attached to the body difference 72 to 74 via the fixing jig 81, but the indirect attachment form is horizontal from the body difference. The fixing jig may be extended, and the bolt holes of the fixing jig may be aligned with the bolt holes 52a of the fixing member 50 shown in FIG. 4A and bolted. Further, as another form, the fixing member 50 shown in FIG. 4A may be directly bolted to the body difference (the above is the installation step). A plurality of panel frame units 60 and their deformed forms are installed on the outer periphery of the steel frame structure of the building, and the outside formed by, for example, a ceramic-based or metal-based siding board, on the plurality of panel frame units 60 and the like. Wall material is attached.

According to the method of transporting and installing the panel frame unit shown in the figure, in a building having two or more floors, the ends of a plurality of panel frames 30 having the corresponding floor heights are rotatable via hinges 40 and 40A. By being connected, each panel frame 30 can be loaded on the truck in a folded posture via hinges 40 and 40A at the time of transportation and transported to the site, so that the length cannot be loaded on the truck in the deployed posture. Even the panel frame unit 60 having the above can be loaded in a folded posture having a length that allows it to be loaded at the time of loading, so that excellent transportability is achieved. For example, as shown in the illustrated example, the panel frame unit 60 corresponding to a four-story building cannot be loaded on a general truck in an unfolded posture and transported, but by adopting the folded posture shown in FIG. 1, it can be moved to a truck. Can be loaded and transported to the site.

Further, after the panel frame unit 60 is transported to the site, the panel frame unit 60 in the folded posture is deployed via the hinges 40 and 40A by lifting one end of the panel frame unit 60 with a heavy machine. By arranging each panel frame 30 on the corresponding floor, each panel frame 30 can be efficiently installed on the corresponding floor, and excellent workability is achieved.

Further, since each panel frame 30 has a corresponding floor height, the upper and lower panel frames 30 connected to each other via the hinges 40 and 40A have a body difference of 72 to 74 between the floors. Since it is firmly fixed, a connection structure between the steel frame frame and the panel frame unit 60 having high structural stability is formed.

It should be noted that the configuration or the like described in the above embodiment may be another embodiment in which other components are combined, and the present invention is not limited to the configuration shown here. This point can be changed without departing from the spirit of the present invention, and can be appropriately determined according to the application form thereof.
