Summary of the Invention

Problems to be Solved by the Invention

[0005] However, none of the above-mentioned patent documents disclose a method for efficiently lifting a post-fit panel, which is to be fitted into the temporary opening, to the vicinity of the temporary opening.

[0006] Furthermore, when using a method of lifting the post-installation panel by hooking a lifting device such as a chain block onto a beam on the indoor side of the building, it is difficult to lift the post-installation panel to a height close to the beam, and it is not easy to fit the post-installation panel into a temporary opening made at a height close to the beam.

[0007] In view of the above circumstances, this invention aims to provide a lifting device and a method for lifting a post-fitting panel that can efficiently position a post-fitting panel near a temporary opening in an exterior wall panel. [Means for solving the problem]

[0008] The lifting device of this invention is a lifting device for lifting an object in order to solve the above problems, A three-dimensional rail section having an mounting position where the above-mentioned target member is attached, a top position located higher than the mounting position, and a removal position located on the opposite side of the mounting position and lower than the top position, where the target member is removed in a state where it is upside down compared to when it is attached at the mounting position. A moving member that can be positioned at the mounting position of the three-dimensional rail section at one end, has an intermediate section that spans the top position, and moves the target member to the removal position by being pulled at the other end, A drive unit that pulls the other end of the above-mentioned movable member to move the movable member in the lifting direction, It is characterized by having the following features.

[0009] With the above configuration, the post-fitting panel, as the target component, can be efficiently positioned near the temporary opening in the exterior wall panel. Furthermore, since the top position of the three-dimensional rail section can be, for example, near the position of the building's beams, it becomes easy to position the post-fitting panel in the correct orientation near the temporary opening, which is opened at a height close to the building's beams.

[0010] In the above-described lifting device, a mounting jig for temporarily attaching the target member is provided to be movable along the three-dimensional rail section between the mounting position, the top position, and the removal position, and one end of the movable member may be connected to the mounting jig. This makes it possible to suppress damage to the target member compared to a method in which the target member is directly connected to one end of the movable member and the target member is lifted by pressing it against the three-dimensional rail section.

[0011] In the above-described lifting device, the mounting jig may be engaged with the three-dimensional rail section such that it cannot be detached from the three-dimensional rail section at least at the removal position. This prevents the mounting jig from unintentionally detaching from the three-dimensional rail section at the removal position.

[0012] In the above-described lifting device, the moving member is a wire-like member or a chain, and the three-dimensional rail section may be provided with a pulley or sprocket on which the moving member is attached.

[0013] Furthermore, the method for lifting a post-fit panel according to this invention is characterized in that the post-fit panel, which is fitted from the indoor side of the building into a temporary opening formed in an exterior wall panel attached to the building's structure, is used as the member to be lifted, the lifting device is positioned on the indoor side of the building, the post-fit panel is set upside down at the mounting position, and the post-fit panel is lifted to the removal position near the temporary opening in the normal upright position by inversion.

[0014] In the lifting method for the post-installed panel described above, an H-shaped steel beam with a horizontally positioned web is provided as the structural frame of the building, and the lower part of the three-dimensional rail section on the removal position side may be hooked onto the H-shaped steel beam. This allows the structural frame to bear the load of the post-installed panel when it is moved to the removal position, thereby improving the stability of the lifting device during lifting.

[0015] Furthermore, in the method for lifting the post-fitted panel described above, the moving member may pass through the upper end of the flange located on the indoor side of the H-shaped steel.

[0016] Furthermore, the method for lifting the post-fit panel described above includes the step of assembling the post-fit panel on a fabricated frame with a rotating mechanism, which is positioned on the indoor side of the building, so that the exterior wall side is facing upwards and is approximately horizontal. The process involves tilting the above-mentioned post-fitting panel by the above-mentioned rotation mechanism so that the outer wall surface faces indoors and is upside down, and then removing it from the above-mentioned fabricated frame. The process involves installing the removed post-fitting panel in the above mounting position in an inverted orientation, It may include. [Effects of the Invention]

[0017] This invention offers the advantage of being able to appropriately and efficiently lift a post-installation panel near a temporary opening in an exterior wall panel. [Brief explanation of the drawing]

Mode for Carrying Out the Invention

[0019] Hereinafter, embodiments of the present invention will be described based on the accompanying drawings. As shown in Figure 1, the structure 5 for the exterior wall panel during construction has a structure in which multiple horizontally elongated exterior wall panels 51 are arranged vertically and connected to each other by first base materials (vertical furring strips) 52, forming a unified structure that is attached to the building's frame. In the example shown in Figure 1, there are six first base materials 52, and each first base material 52 is made of open-section steel material such as lip channel steel or closed-section steel material such as square steel pipe.

[0020] The exterior wall panel 51 described above is a metal sandwich panel in which a non-combustible heat insulating material 51a is sandwiched between steel plates 51b and 51c, as shown in Figures 2(A) and 2(B). When two exterior wall panels 51 are placed one above the other, two horizontally elongated recesses 51d formed on the lower end surface of the upper exterior wall panel 51 fit into two horizontally elongated protrusions 51e formed on the upper end surface of the lower exterior wall panel 51, so that the upper and lower exterior wall panels 51 do not shift out of plane relative to each other.

[0021] Furthermore, for example, by using the ground assembly frame 1 for the construction structure shown in Figure 3, an exterior wall panel, in which multiple exterior wall surface materials 51 are arranged vertically and connected by a first base material 52, can be assembled at a location different from the exterior wall mounting point of the building's frame to which the exterior wall panel will be attached. The ground assembly frame 1 for the construction structure is, for example, made up of multiple columnar members 11 and beam-shaped members 12 arranged vertically and horizontally, but its structure is not limited to that shown in Figure 3.

[0022] After setting the first base material 52 onto the ground frame 1, the worker sets the exterior wall panel 51, and screws or the like into the upper side of the set exterior wall panel 51 to fix the exterior wall panel 51 to the first base material 52 that was set earlier. By repeating this process, the construction structure 5 for the exterior wall panel is created.

[0023] In the above-mentioned structure 5 for the exterior wall panel during construction, for example, at the location where the second row of exterior wall paneling 51 from the top should be present, the first base material 52 is divided and separated vertically, the uppermost exterior wall paneling 51 is attached to the upper first base material 52, the second row of exterior wall paneling 51 and the first base material 52 from the top are not attached, and from the third row from the top down, all exterior wall paneling 51 are attached to the lower first base material 52. In other words, in this example, the structure 5 for the exterior wall panel during construction has a structure in which only the second row from the top lacks both the exterior wall paneling 51 and the first base material 52.

[0024] Furthermore, as shown in Figure 1, the construction structure 5 of the exterior wall panel includes a second base material 53 having a vertical length extending from, for example, the uppermost exterior wall panel 51 to the sixth exterior wall panel 51. The second base material 53 is connected to the first base material 52 located above and below, spanning the area where the first base material 52 is absent (a temporary opening). The second base material 53 can be attached to the first base material 52 using the ground assembly frame 1 for the construction structure. The second base material 53 is detachably attached to the first base material 52 so that it can be removed after the construction structure 5 has been attached to the building frame 7.

[0025] The first base material 52 described above is, for example, made of channel steel having two opposing surfaces and a closed surface connecting these opposing surfaces, and the exterior wall surface material 51 is fixed with screws on one side of the opposing surfaces.

[0026] Furthermore, as shown in Figure 4, the building frame 7 to which the construction structure 5 of the exterior wall panel is attached includes, for example, roof beams 71 that support the roof 7A, wind-resistant beams 72, roof-side exterior wall fixing beams 72A, floor beams 73, etc. When attaching the construction structure 5 of the exterior wall panel to the building frame 7, for example, the other side of the opposing surface of the first base material 52 is fixed to the wind-resistant beams 72, roof-side exterior wall fixing beams 72A, floor beams 73, etc. in the building frame 7 using fasteners 4, angles 400, etc.

[0027] Furthermore, for example, the second base material 53 may also be channel steel, and by positioning its closed surface facing the closed surface of the first base material 52, it is attached to the first base material 52 in a horizontal position within the horizontal plane. Bolt insertion holes are formed in the closed surface at a predetermined pitch, for example, and the second base material 53 is detachably attached to the first base material 52 by bolts and nuts threaded through these bolt insertion holes. Note that even if the first base material 52 and the second base material 53 are rectangular steel pipes having a closed cross-sectional shape, a similar bolt attachment structure can be used. Moreover, the structure for detachability described above is not limited to a structure using bolts and nuts.

[0028] As described above, after fixing the first base material 52 of the exterior wall panel 51 to the building frame 7, the second base material 53 is removed from the first base material 52. Since the first base material 52 is fixed to the building frame 7 as described above, even if the second base material 53 is removed from the first base material 52, the exterior wall panel 51 will not detach from the building frame 7. By removing the second base material 53 from the first base material 52 in this way, a temporary opening is formed where the exterior wall panel 51 is not present and the second base material 53 is also absent, that is, an opening that can be used during construction without being obstructed by the base material. One example of use during construction is bringing scaffolding out from the indoor side.

[0029] The first base material 52 of the exterior wall surface material 51 located above the temporary opening is connected to the roof-side exterior wall fixing beam 72A, as shown in Figure 5, when the temporary opening is in use, that is, when the second base material 53 is removed from the first base material 52.

[0030] As shown in Figure 6, one horizontally positioned piece of an L-angle 72a is welded to the lower part of the roof-side exterior wall fixing beam 72A, while the other vertically positioned piece of this L-angle 72a faces outwards and confronts the first base material 52. The head of a base 72b containing a bolt 72c is welded to the lower surface of the one side of this L-angle 72a.

[0031] The fastener 4 comprises an L-angle 4a, a nut 4b, a spacer 4d, and a spacer bolt 4c. The spacer 4d creates a gap between the vertical piece of the L-angle 4a and the first base material 52, into which the other piece of the L-angle 72a can be inserted. A vertical insertion hole is formed in the horizontal piece of the L-angle 4a, and the bolt 72c is inserted through this hole, allowing the nut 4b to support the load of the uppermost exterior wall panel. Furthermore, by adjusting the vertical position of the nut 4b, the uppermost exterior wall panel can be moved up and down. Note that a vertical screw hole is formed in the horizontal piece of the L-angle 4a at the back of the page in Figure 6, and a bolt (not shown) is screwed into this screw hole from below. By screwing in this bolt, its upper tip can be pressed against the lower surface of one side of the L-angle 72a.

[0032] Next, an example of attaching the post-fit panel 501 to the temporary opening will be described. For example, as shown in Figure 7, a lifting device 3 for lifting the post-fit panel 501 as the lifting target is placed on the top floor of the building after the temporary opening has finished being used. This lifting device 3 comprises a three-dimensional rail section 31, a moving member 32, a drive unit 33, a mounting jig 34, and a stopper 35.

[0033] As shown in Figure 8, the three-dimensional rail section 31 comprises two side frame sections 31a positioned spaced apart to the left and right, and a plurality of beam sections 31b, for example, four beam sections 31b, that span horizontally across these side frame sections 31a. Of the four beam sections 31b, the two in the center are positioned at the highest point, and the two on either side are positioned at a width wider than the two in the center. The side frame sections 31a and beam sections 31b are made of, for example, metal pipes. The lower end of the side frame section 31a, which forms the indoor leg, is placed on the top floor and is temporarily fixed, for example, to a fall prevention handrail on the edge of the floor slab using a single-pipe clamp. On the other hand, the lower end of the side frame section 31a on the outdoor side is supported by a wind-resistant beam 72 located below the roof-side exterior wall fixing beam 72A. This support will be described in detail later.

[0034] Furthermore, the three-dimensional rail section 31 has an installation position P1 where the post-fit panel 501 is attached, a top position P2 located higher than the installation position P1, and a removal position P3 on the opposite side (outdoor side) of the installation position P1, located lower than the top position P2, where the post-fit panel 501 is removed in an inverted state compared to the state in which it is attached at the installation position P1.

[0035] The movable member 32 has one end positioned at the mounting position P1 of the three-dimensional rail section 31, and its middle section is stretched across to the top position P2. When the other end is pulled, it moves to lift the post-fit panel 501 to the removal position P3. In this embodiment, the movable member 32 is a wire-like member, and a pulley 31c is provided at the center of each beam section 31b of the three-dimensional rail section 31, to which the movable member 32 is attached. Alternatively, a chain may be used as the movable member 32, and a sprocket may be provided instead of the pulley 31c. Alternatively, it is possible to have a structure in which the wire-like member, which is the movable member 32, slides on the beam section 31b without providing the pulley 31c.

[0036] The drive unit 33 consists of, for example, an electric motor or a winch with manual recoil, and by winding up the other end of the moving member 32, the moving member 32 can be moved in the lifting direction of the rear-fitting panel 501. It should be noted that the drive unit 33 is not limited to being placed on the floor of the building; it can also be mounted on the wind-resistant beam 72, or attached to the back (lower) side of the top position P2 of the lifting device 3.

[0037] The mounting jig 34 described above is a jig to which the post-fit panel 501 is temporarily attached during the lifting process. It has two long horizontal bar members 34a that are longer than the distance between the side frame portions 31a, and two connecting portions 34b that connect these two horizontal bar members 34a. This mounting jig 34 slides along the outer surface of the side frame portions 31a of the three-dimensional rail portion 31 and can move between the mounting position P1, the top position P2, and the removal position P3. In addition, one end of the movable member 32 is connected to this mounting jig 34, and the post-fit panel 501 is lifted by the movement of the mounting jig 34 caused by the movement of the movable member 32. Furthermore, the horizontal bar member 34a of the mounting jig 34 has a bolt insertion hole, and by passing a bolt through this bolt insertion hole and then through a hole formed in the vertical furring strip member 502 of the post-fitting panel 501, and screwing a nut onto the bolt, the post-fitting panel 501 can be temporarily attached to the mounting jig 34.

[0038] The stopper 35 stops the moving member 32 when the mounting jig 34 reaches the removal position P3. For example, the moving member 32 has a projection on its back side that does not come into contact with the pulley 31c. The stopper 35 is fixed to the beam portion 31b below the removal position P3 and is positioned so as to strike the projection when the mounting jig 34 reaches the removal position P3. Alternatively, the stopper 35 may strike the mounting jig 34 when it reaches the removal position P3 to stop its descent. Furthermore, the drive unit 33 may be a motor that automatically stops when a certain load is applied.

[0039] In this embodiment, the method for lifting the post-fit panel 501 uses the lifting device 3 positioned on the floor of the building, as shown in Figures 9 and 10. The lower end of the side frame portion 31a of the lifting device 3 on the outdoor side (the side of the removal position P3) is hooked onto a wind-resistant beam 72 made of H-shaped steel with its web positioned horizontally. The movable member 32 is positioned to pass through the upper end of the flange located on the indoor side of the H-shaped steel.

[0040] Furthermore, a low-friction metal member may be fitted to the upper end of the flange of the H-shaped steel, for example, so that the movable member 32 passes over the low-friction member. Also, the hooking of the lower end of the side frame portion 31a on the outdoor side (the side of the removal position P3) to the wind-resistant beam 72 is not limited to placing the lower end on the web of the wind-resistant beam 72, but may also be done by inserting a notch formed in the lower end into the upper part of the flange on the indoor side of the wind-resistant beam 72. In addition, since this lifting device 3 is used by hooking it onto the wind-resistant beam 72, the side frame portion 31a has a roughly hook shape, but it is not limited to this, and the lower end of the side frame portion 31a on the outdoor side (the side of the removal position P3) may be supported on the floor of the building, that is, the side frame portion 31a may have an inverted U shape. However, if the side frame portion 31a has the above-described approximate hook shape and is used by being hooked onto the wind-resistant beam 72, the load of the post-fit panel 501 that has been moved to the removal position P3 can be supported by the wind-resistant beam 72, thereby improving the stability of the lifting device 3 during lifting. In addition, compared to a structure in which the side frame portion 31a has an inverted U shape, the overall length of the side frame portion 31a can be shortened, which makes it possible to lighten the three-dimensional rail portion 31 and make it easier to move.

[0041] In lifting the post-fit panel 501 using the lifting device 3 described above, the post-fit panel 501 is set upside down on the mounting jig 34 at the mounting position P1. After this setting, the drive unit 33 is operated to retract the moving member 32. When the post-fit panel 501 moves beyond the top position P2 to the removal position P3, the post-fit panel 501 returns to its normal upright position near the temporary opening due to the upside-down inversion described above. The bolts and nuts used for the temporary mounting are removed from the post-fit panel 501 at the removal position P3. The worker then performs the task of fitting the post-fit panel 501, which was removed at the removal position P3, into the temporary opening, for example, on a high-altitude work platform or rolling tower positioned near each side frame portion 31a of the three-dimensional rail portion 31.

[0042] The process of fitting the post-fit panel 501 into the temporary opening will be explained with reference to Figure 11. Like the other exterior wall surface material 51, the post-fit panel 501 has a recess 51d on its lower side, which is a lower engaging portion, and a protrusion 51e on its upper side, which is an engaging portion that engages with the lower side of the exterior wall surface material 51 located above it. The post-fit panel 501 also has vertical furring strip members 502 as a base material.

[0043] When fitting the post-fitting panel 501 into the temporary opening, the fastener 4 is used to lift the exterior wall material 51 and the first base material 52 located above the post-fitting panel 501 so that the upper height position of the temporary opening is higher than the upper height position of the post-fitting panel 501.

[0044] Then, when fitting the post-fitting panel 501 into the temporary opening, the upper protrusion 51e of the exterior wall surface material 51 located below the post-fitting panel 501 is engaged with the recess 51d, which is the lower engaging portion of the post-fitting panel 501.

[0045] Next, the upper exterior wall panel 51 is lowered using the fastener 4. This lowering operation causes the convex portion 51e, which is the upper engaging portion of the post-fit panel 501, to engage with the recess 51d on the lower side of the exterior wall panel 51 located above the post-fit panel 501.

[0046] Then, after fitting the post-fit panel 501 into the temporary opening as described above, the second base material 53, which was temporarily removed (not shown in the figure), is connected to the vertical furring strip member 502 of the post-fit panel 501, and further, this second base material 53 is connected to the first base material 52 of the upper and lower exterior wall surface material 51. Note that the fitting process of the post-fit panel 501 is not limited to the method using the fastener 4 as shown in Figure 11.

[0047] With the lifting method using the lifting device 3 described above, the post-fitting panel 501, which is the target of lifting, can be efficiently positioned near the temporary opening of the structure 5 during the construction of the exterior wall panel. In addition, the top position P2 of the three-dimensional rail section 31 can be made close to the position of the roof-side exterior wall fixing beam 72A, making it easy to fit the post-fitting panel 501 into the temporary opening that is opened at a height close to the roof-side exterior wall fixing beam 72A.

[0048] Furthermore, in this embodiment, the lifting device 3 is equipped with a mounting jig 34, which helps to suppress damage to the post-fitting panel 501. The lifting method of this invention also includes a method in which the post-fitting panel 501 is directly connected to one end of the movable member 32 without the mounting jig 34, and the post-fitting panel 501 is lifted by bringing it into contact with the side frame portion 31a of the three-dimensional rail portion 31. However, the form using the mounting jig 34 is preferable in suppressing damage to the post-fitting panel 501.

[0049] Furthermore, the mounting jig 34 may be engaged with the side frame portion 31a of the three-dimensional rail portion 31 so as to prevent it from detaching from the side frame portion 31a of the three-dimensional rail portion 31 at least at the removal position P3. This prevents the mounting jig 34 from unintentionally detaching from the three-dimensional rail portion 31 at the removal position P3. Such engagement can be achieved, for example, by an engaging portion 34c fixed to one of the two horizontal bar members 34a of the mounting jig 34, as shown in Figure 16. This engaging portion 34c has a cylindrical portion 34ca that can move within each side frame portion 31a, and a protruding portion 34cb that protrudes from a slit portion 31aa formed in the side frame portion 31a and is joined to the horizontal bar member 34a. The width of the slit portion 31aa is narrower than the diameter of the cylindrical portion 34ca. Furthermore, the engaging portion 34c is fixed to the horizontal bar member 34a located on the lower side at the removal position P3. Note that if channel steel is used as the side frame portion 31a, the processing time required to form the slit portion 31aa can be reduced.

[0050] Furthermore, the lifting method in this embodiment is the method shown in Figures 9 and 10, and before attaching the post-fit panel 501 to the mounting jig 34 at the mounting position P1, The process involves assembling the above-mentioned post-fit panel 501 on a fabricated frame 2 with a rotating mechanism, which is positioned on the indoor floor of the above-mentioned building, so that the exterior wall side is facing upward and is approximately horizontal. The process involves tilting the above-mentioned post-fit panel 501 by the above-mentioned rotation mechanism so that the outer wall surface faces indoors and is upside down, and then removing it from the above-mentioned fabricated frame 2. The process includes the step of attaching the removed post-fitting panel 501 to the mounting jig 34 of the three-dimensional rail section 31 in an upside-down position at the mounting position P1.

[0051] For example, the fabrication frame 2 for manufacturing the post-fit panel 501 shown in Figure 12 comprises a base portion 21, a mounting surface portion 22, a rotating support portion 23, a vertical positioning portion 24, and a movable horizontal positioning portion 25, as shown in Figures 13 and 14.

[0052] The base section 21 comprises two horizontal base sections 21a made of H-shaped steel or the like, spaced apart from each other. Two casters 21b are attached to the underside of each horizontal base section 21a.

[0053] The mounting surface 22 has two main beams 22a that are long in a direction perpendicular to the longitudinal direction of the two horizontal bases 21a. These two main beams 22a are made of H-shaped steel or the like and are spaced apart from each other in a direction perpendicular to the separation direction of the horizontal bases 21a. The two main beams 22a are welded to the ends of two smaller beams 22b made of square steel pipe or the like, which are placed between the main beams 22a. One face of an angle steel 22c having two orthogonal faces is fixed to each main beam 22a by bolts or the like, and the other face forms the support surface for the vertical furring strip member 502 in the post-fit panel 501. That is, the other face of the angle steel 22c is perpendicular to the longitudinal direction of the main beam 22a, and the vertical furring strip member 502 can be fixed to this other face by bolts or the like while in contact with it. The mounting surface 22 allows the vertical furring strip member 502 to be positioned and fixed in the design location. Furthermore, the exterior wall panel 51 can be placed on top of the vertical furring strip member 502, and the exterior wall panel 51 can be fixed to the vertical furring strip member 502 by driving screws 503 into the upper side of the vertical furring strip member 502 from above the exterior wall panel 51.

[0054] The rotating support section 23 comprises a first support section 231 and a second support section 232, which are erected on the two horizontal base sections 21a. A support shaft 231a is provided on the upper part of the first support section 231, parallel to the longitudinal direction of the main beam 22a. The support shaft 231a is inserted into the side surface of each small beam 22b of the mounting surface section 22 at approximately the center position, and the mounting surface section 22 rotates around the support shaft 231a.

[0055] The second support column 232 is positioned so that its upper end is in contact with the side surface of one of the main beams 22a. By fixing the main beam 22a at this upper end with bolts or the like, the mounting surface 22 can be positioned horizontally. On the other hand, by removing these bolts or the like, the mounting surface 22 can be allowed to rotate.

[0056] In other words, as shown in Figure 15, the rotating support portion 23 rotatably supports the mounting surface portion 22 with the rotation center being the horizontal direction perpendicular to the longitudinal direction of the vertical furring strip member 502, and can assume a first rotating position in which the mounting surface portion 22 is positioned horizontally and a second rotating position in which the mounting surface portion 22 is positioned vertically.

[0057] The vertical positioning section 24 is made of, for example, an angle steel having two orthogonal surfaces, one of which is fixed to one of the main beams 22a by bolts or the like, and the upper part of this one surface contacts the upper edge of the exterior wall panel 51, defining the vertical position of the exterior wall panel 51.

[0058] The movable horizontal positioning section 25 is provided on one end of the mounting surface section 22. The movable horizontal positioning section 25 comprises a contact section 251 made of angle steel having two orthogonal surfaces, and a support section 252 that rotatably supports the contact section 251. When positioning, the contact section 251 positions the surface by having the edge of one of the surfaces, which is positioned horizontally, strike the side surface of the exterior wall surface material 51. The side surface of the exterior wall surface material 51 has projections that form the vertical joints of the exterior wall, and the edge of one of the surfaces strikes the side surface at a position closer to the outside than the projections. In addition, the height of one of the surfaces is set to be higher than the height of the projections. The other surface of the contact section 251 is fixed to the upper side of the support section 252.

[0059] The support section 252 consists of angle steel sections arranged vertically, with two orthogonal surfaces. The contact section 251 is fixed to the upper side of one of the surfaces with bolts or the like. The lower side of the other surface of the support section 252 is fixed to each main beam 22a with two axial members such as bolts. In other words, the movable horizontal positioning section 25 is fixed in position by two axial members, and by removing one of the two axial members and rotating it with the other, the contact section 251 is detached from the side surface of the outer wall surface material 51. Each main beam 22a has an insertion hole through which the axial members can be inserted.

[0060] With the above-described fabricated frame 2, in the first rotational position shown above, the exterior wall panel 51 can be positioned in the correct design position on the vertical furring strip member 502 which is fixed on the mounting surface 22, as shown in Figure 15, and the exterior wall panel 51 can be fixed to the vertical furring strip member 502 by driving screws 503 into the upper side thereof.

[0061] Furthermore, in the second rotational position described above, the operation to remove the post-fitting panel 501 (vertical furring strip member 502) from the mounting surface 22 (such as removing bolts) can be performed from the side rather than from directly below, allowing the operation to be performed in a more comfortable position.

[0062] In the second rotational position described above, the movable horizontal positioning unit 25 is rotated to separate it from the side surface of the exterior wall material 51, thereby allowing the post-fit panel 501 to be detached from the fabricated frame 2 without the movable horizontal positioning unit 25 hitting any protrusions on the side surface of the exterior wall material 51.

[0063] Although embodiments of this invention have been described above with reference to the drawings, this invention is not limited to the illustrated embodiments. Various modifications and variations can be made to the illustrated embodiments within the same scope as this invention, or within the equivalent scope. [Explanation of Symbols]
