JP 2016-94787 A

As with the method of mounting exterior wall panels described in Patent Document 1 above, when mounting multiple panels such as exterior wall panels to a column-shaped base material such as a building's furring strip, it is common to stack the panels one by one from the bottom up.

However, if you want to complete the interior finishing work on the upper floors of a building before the interior finishing work on the lower floors of the building, or if you want to use the lower part of the exterior wall as a loading entrance, etc., the above installation method cannot be used.

In view of the above circumstances, the present invention aims to propose a panel mounting method and panel support that can mount multiple panels on a building's column-shaped base material one panel at a time, starting from the top.

One aspect of the panel mounting method according to the present invention is a panel mounting method for mounting multiple panels to a column-shaped base material of a building.

One embodiment of the panel mounting method includes first to third steps.

The first step is to move a lower panel, which is supported from below by a panel support connected to a hanging device, from below an upper panel fixed to the base material, to a connection position where the upper end of the lower panel is inserted into the lower end of the upper panel.

The second step is to fix the upper end of the lower panel in the connection position to the base material while the lower panel is supported by the panel support. The third step is to remove the panel support from the lower panel.

In one embodiment of the panel mounting method, the first step, the second step, and the third step are repeated in this order to mount the multiple panels to the base material.

A panel support according to one aspect of the present invention is a panel support used in the panel mounting method.

The panel support of one embodiment includes a bottom member that supports the lower panel from below, a first standing member and a second standing member that stand upward from the bottom member so as to be positioned on both sides of the thickness direction of the lower panel, and a connection part that is provided at the upper end of the first standing member and can be connected to the hanging device.

The space surrounded by the bottom member, the first standing member, and the second standing member is a panel storage space that is open upward.

One aspect of the panel mounting method according to the present invention is a method for mounting multiple panels to a column-shaped base material of a building, which allows the panels to be mounted one by one from the top down.

In addition, one aspect of the panel support according to the present invention provides a panel support that can be used to attach multiple panels to a column-shaped base material of a building, by attaching the panels one by one from the top.

The following embodiment relates to a panel installation method, and more specifically, to a method for installing multiple panels in order from the top onto a column-shaped base material of a building.

(1) Overview Figures 1 to 3 show a panel mounting method according to one embodiment. The panel mounting method is a method for mounting a plurality of panels P1, P2, P3, ... in order from above to a base material 1 of a building. This panel mounting method is used, for example, when constructing the exterior wall of a building.

The panel mounting method uses a hanging device 6, a panel support 7 connected to the hanging device 6, and a mounting fixture 9 for mounting the panels P1, P2, P3, ....

In the following, each configuration will be explained based on the mounting state shown in Figure 3B, with the side on which the multiple panels P1, P2, P3, ... are located relative to the base material 1 being the front, the opposite side being the rear, and the horizontal direction perpendicular to the front-to-rear direction being the left-to-right direction.

(2) Description of each component (2-1) Base material The base material 1 is a columnar member with its longitudinal direction in the up-down direction, such as a pillar or vertical furring strip that constitutes the building's framework. Each of the multiple panels P1, P2, P3, ... is attached to each of the multiple base materials 1 that are arranged in a row at intervals in the horizontal direction (left-right direction). The multiple base materials 1 are either multiple pillars, or multiple vertical furring strips, or a combination of at least one pillar and at least one vertical furring strip.

(2-2) Panel Each of the panels P1, P2, P3, ... is a sandwich panel used as an exterior material, an interior material, etc. In this embodiment, the shapes, dimensions, and materials of the panels P1, P2, P3, ... are the same as each other. Each of the panels P1, P2, P3, ... is a substantially rectangular plate-like panel with the left-right direction as the longitudinal direction, the up-down direction as the short direction, and the front-rear direction as the thickness direction (see FIG. 6). The left-right length of each of the panels P1, P2, P3, ... is, for example, 3 to 7 m. Note that, of the panels P1, P2, P3, ..., the panel located at the top is P1, the panel located second from the top is P2, and so on.

Each of the multiple panels P1, P2, P3, ... has a cover portion 11 that protrudes downward on the front side portion (front end) of its lower end. Each of the multiple panels P1, P2, P3, ... has a convex portion 12 that protrudes downward on the center portion in the front-to-rear direction of its lower end. The lower end of the cover portion 11 is located lower than the lower end of the convex portion 12. Each of the multiple panels P1, P2, P3, ... has a second cover portion 13 that protrudes downward on the back side portion (rear end) of its lower end.

Each of the panels P1, P2, P3, ... has a recessed step 14 that is open upward and forward at the front side portion (front end) of its upper end. Each of the panels P1, P2, P3, ... has a recessed portion 15 that is open upward at the center portion of its upper end in the front-to-rear direction.

The recessed step 14 is located in front of the recess 15 and extends below the recess 15. A recessed streak 16 that is recessed toward the base material 1 (i.e., rearward) is provided in the portion of the recessed step 14 that is below the recess 15. In other words, each of the multiple panels P1, P2, P3, ... has a recessed streak 16 on the front side of its upper end (front end).

The multiple panels P1, P2, P3, ... are connected to each other by fitting the convex portion 12 of the upper panel Pn into the concave portion 15 of the lower panel Pn+1, the cover portion 11 of the upper panel Pn into the concave step portion 14 of the lower panel Pn+1, and the second cover portion 13 of the upper panel Pn into the space behind the concave portion 15 of the lower panel Pn+1.

Each of the multiple panels P1, P2, P3, ... is a sandwich panel in which a core material 19 is sandwiched between two metal skins 17, 18. Each of the metal skins 17, 18 is formed into a desired shape by rolling or pressing a flat metal plate. The flat metal plate has a thickness of about 0.27 to 1.6 mm, and may be a painted steel plate, a zinc-plated steel plate, an aluminum-zinc alloy-plated steel plate, a Galvalume steel plate (registered trademark), an SGL (registered trademark) steel plate, or the like, but is not limited to these.

The core material 19 is a resin foam or a fibrous inorganic material, or a combination thereof, and has heat insulating and fire resistance. Examples of the resin foam include polyisocyanurate foam, urethane foam, and phenol foam. The fibrous inorganic material is, for example, a plurality of blocks of rock wool or glass wool bound with a binder or the like arranged in the form of a single plate. The core material 19 located on the outer periphery of the panel is, for example, a highly fire-resistant inorganic material such as gypsum or calcium silicate.

As shown in FIG. 4A, the recess 15 includes a first side wall 150 formed by bending the upper end of the metal outer skin 17 into a predetermined shape, and a second side wall 151 formed by bending the upper end of the metal outer skin 18 into a predetermined shape. The inside of each of the side walls 150 and 151 is hollow and is not filled with the core material 19. The bottom surface (the surface facing forward) of the recessed streak portion 16 is located behind the front surface of the first side wall 150.

The protruding portion 12 is composed of the lower end of the metal skin 17, the lower end of the metal skin 18, and the core material 19 located between them. The cover portion 11 is formed by bending a part of the metal skin 17 into a U-shape, is hollow inside, and is not filled with the core material 19. The groove portion 16 is formed by bending a part of the metal skin 17, and is continuous with the first side wall 150.

As shown in Figures 4A and 4B, each of the multiple panels P1, P2, P3, ... has a through hole 20 that penetrates from the groove portion 16 toward the base material 1 (rear side). The number of through holes 20 formed in each of the multiple panels P1, P2, P3, ... corresponds to the number of base materials 1 to which the multiple panels P1, P2, P3, ... are attached, and in this embodiment, is twice the number of base materials 1. The through holes 20 are formed, for example, at the construction site. Note that the through holes 20 may also be formed at a manufacturing plant for the multiple panels P1, P2, P3, ....

(2-3) Suspension Device The suspension device 6 is a crane or the like. As shown in Fig. 1A and other figures, the suspension device 6 has a suspension member 60 such as a rope, a wire, a belt, a chain, or the like. The suspension device 6 is connected to the panel support 7 via the suspension member 60.

(2-4) Panel Support The panel support 7, as shown in Figures 1A, 1B, 5, and 6, is a member that supports the lower panel Pn+1 (panel P2) that it supports from below so that the upper end portion thereof is exposed.

The receiving portion 701 is provided on the center of the base portion 700 in the front-rear direction. The receiving portion 701 is block-shaped with the left-right direction as the longitudinal direction. The receiving portion 701 is configured to receive the protruding portion 12 of the lower panel Pn+1 and prevent the covering portion 11 of the lower panel Pn+1 from hitting the base portion 700. The receiving portion 701 is provided with a protruding portion 702 that protrudes upward so as to be inserted between the protruding portion 12 of the lower panel Pn+1 and the second covering portion 13. A third connecting portion 76 is provided on the outer surface of the base portion 700 in the left-right direction.

A pair of first standing members 71 protrude upward from the front end of the base portion 700 with a gap between them in the left-right direction. A pair of second standing members 72 protrude upward from the rear end of the base portion 700 with a gap between them in the left-right direction. In this embodiment, the pair of first standing members 71 and the pair of second standing members 72 have the same upper end position, and the upper end position is lower than the lower panel Pn+1 supported on the receiving portion 701. Note that the pair of second standing members 72 and the pair of first standing members 71 may have upper end positions different from each other.

A connection portion 73 is provided at the upper end of each of the pair of first standing members 71. A second connection portion 74 is provided at the upper end of each of the pair of second standing members 72. In this embodiment, each of the connection portions 73, 74, and 76 is an eye bolt.

The space surrounded by the bottom member 70, a pair of first standing members 71, and a pair of second standing members 72 is the panel storage space S1 (see FIG. 1A), which is open upward and to the left and right.

The upper support member 75 is a rope or the like. As shown in Figures 1A and 6, the upper support member 75 is attached so as to span the hanging member 60 connected to the connection portion 73 and the second connection portion 74, thereby supporting the upper end portion of the lower panel Pn+1 housed in the panel housing space S1. The upper support member 75 is detachable from the hanging member 60 and the second connection portion 74.

As shown in Figures 5 and 6, the panel support 7 includes a pair of left and right support parts 107, each of which is made up of a bottom member 70, standing members 71 and 72, connecting parts 73, 74 and 76, an upper support member 75, and a tension member 77, and further includes a connecting member 78 that connects the pair of left and right support parts 107 together. The pair of support parts 107 are positioned with a gap between them in the left-right direction.

In this embodiment, the connecting member 78 is composed of a pair of upper and lower connecting bars 780. The pair of support parts 107 are integrated by fixing each of the pair of upper and lower connecting bars 780 to each of the pair of first standing members 71 of one support part 107 and each of the pair of first standing members 71 of the other support part 107. The distance between the pair of support parts 107 is appropriately set corresponding to the left-right length of the lower panel Pn+1 so that the lower panel Pn+1 can be stably supported. The panel support 7 is attached to the left-right center of the lower panel Pn+1.

4A and 4B, the mounting fixture 9 includes a first mounting member 21 attached to the lower panel Pn+1 so as to penetrate therethrough, a second mounting member 22 attached to the base material 1, and a fixing member 23 that fixes the first mounting member 21 and the second mounting member 22. The mounting fixture 9 further includes a fastener 24 for fixing the second mounting member 22 to the base material 1.

As shown in Figures 4A, 4B, and 7, the first mounting member 21 includes a long plate portion 210 configured to fit into the groove portion 16, and a bolt 211 configured to protrude from a part of the long plate portion 210 and penetrate the lower panel Pn+1. In this embodiment, a pair of bolts 211 protrude from the long plate portion 210. The long plate portion 210 has a left-right length that is longer than the left-right length of the base material 1. The pair of bolts 211 are positioned with a gap between them in the left-right direction. The gap between the pair of bolts 211 is the same as the gap between a pair of adjacent through holes 20 provided in the lower panel Pn+1.

The second mounting member 22 includes a hook portion 220 that is hooked onto the base material 1, and an insertion portion 221 that extends from the hook portion 220 and through which the bolt 211 is inserted. In this embodiment, the hook portion 220 is provided in a U-shape in a plan view so as to surround the base material 1. A pair of insertion portions 221 protrude in opposite directions (to the right and left) from the U-shaped hook portion 220.

The hook portion 220 has a rear plate portion 222 that runs along the rear surface of the base material 1, and a pair of side plate portions 223 that protrude forward from both the left and right ends of the rear plate portion 222 and run along the left and right side surfaces of the base material 1. The rear plate portion 222 and the pair of side plate portions 223 are each rectangular plate-shaped. An insertion portion 221 protrudes to the right from the front end portion of the right side plate portion 223, and an insertion portion 221 protrudes to the left from the front end portion of the left side plate portion 223.

In this embodiment, each of the pair of insertion portions 221 is a rectangular plate, and an insertion hole 224 through which the bolt 211 is inserted penetrates in the thickness direction (front-rear direction). The insertion hole 224 is an elongated hole that is long in the left-right direction. The length of the insertion hole 224 in the up-down direction is slightly longer than that of the bolt 211.

The rear plate portion 222 of the hook portion 220 is provided with a through hole 225 through which the fastener 24 is inserted. In this embodiment, the rear plate portion 222 is provided with a pair of left and right through holes 225.

The fixing member 23 includes a nut 230 that is attached to the bolt 211 inserted through the insertion portion 221. In this embodiment, since the first mounting member 21 has a pair of bolts 211, the fixing member 23 includes a pair of nuts 230. The pair of nuts 230 are attached to each of the pair of bolts 211 inserted through the pair of insertion portions 221. The fixing member 23 further includes a pair of washers 231 and a pair of spring washers 232.

The fasteners 24 are tapping screws or the like. In this embodiment, the mounting fixture 9 includes a pair of fasteners 24.

The first mounting member 21 described above is attached to the lower panel Pn+1 such that the long plate portion 210 is fitted into the groove portion 16, a pair of bolts 211 are inserted into a pair of through holes 20, and the tip portions of the pair of bolts 211 protrude rearward from the lower panel Pn+1.

The second mounting member 22 is hooked to the base material 1 with the hooking portions 220 arranged to surround the base material 1, and the portions of the pair of bolts 211 of the first mounting member 21 that protrude rearward from the lower panel Pn+1 are inserted into the insertion holes 224 of the pair of insertion portions 221. A pair of fasteners 24 are inserted into the pair of through holes 225 of the hooking portions 220, thereby fastening the second mounting member 22 to the base material 1. When the second mounting member 22 is fastened to the base material 1, the front surfaces of the pair of insertion portions 221 of the second mounting member 22 and the front surface of the base material 1 are approximately flush with each other.

The pair of nuts 230 of the fixing member 23 are fastened to each of the pair of bolts 211 inserted into the pair of insertion portions 221, thereby fixing the first mounting member 21 and the second mounting member 22 in a state in which the long plate portion 210 and the pair of insertion portions 221 sandwich the lower panel Pn+1. A pair of washers 231 and a pair of spring washers 232 are also inserted into the pair of bolts 211, respectively.

(3) Panel Mounting Method Next, the panel mounting method shown in Figures 1 to 3 will be described. The panel mounting method is a method for mounting a plurality of panels P1, P2, P3, ... on a base material 1 of a building in order from above. The panel mounting method includes first to third steps. Each of the first to third steps will be described in detail below.

(3-1) First Step In the first step, of the multiple panels P1, P2, P3, ..., the lower panel Pn+1, which is supported from below by a panel support 7 connected to a hanging device 6, is moved from below the upper panel Pn to a connection position where the upper end of the lower panel Pn+1 is inserted into the lower end of the upper panel Pn to connect them.

More specifically, an upper panel Pn (panel P1) is fixed to the base material 1. The panel P1 is fixed to the base material 1 by a fastener (not shown), such as a screw, that is driven into the base material 1 from the groove portion 16. The panel P1 may also be fixed to the base material 1 by a mounting fixture 9.

As shown in FIG. 1A, first, the lower panel Pn+1 (panel P2) supported from below by the panel support 7 is suspended by the suspension device 6 via the panel support 7 and the suspension member 60. At this time, the upper end of the lower panel Pn+1 is supported by the upper support member 75 attached to the panel support 7, thereby suspending and supporting the lower panel Pn+1 in a position approximately parallel to the vertical direction (see FIG. 6).

Next, while the lower panel Pn+1 is suspended by the suspension device 6, the tension member 77 is pulled from behind the base material 1 to align the lower panel Pn+1 with the front surface of the base material 1.

Next, as shown in FIG. 1B, the first mounting member 21 is attached by penetrating it into the groove portion 16 at the upper end of the lower panel Pn+1, and the portions of the pair of bolts 211 of the first mounting member 21 that protrude from the lower panel Pn+1 toward the base material 1 (rear side) are inserted into the pair of insertion portions 221 of the second mounting member 22, and the hook portions 220 of the second mounting member 22 are hooked onto the base material 1.

Next, the pair of washers 231, the pair of spring washers 232, and the pair of nuts 230 are attached in this order to the pair of bolts 211 of the first mounting member 21. At this time, each of the pair of nuts 230 is stopped at a temporary fastening position before (rearward) of the fastening position where the pair of nuts 230 contact the pair of insertion portions 221 via the pair of washers 231 and the pair of spring washers 232.

Next, the upper support member 75 is removed from the panel support 7, and the lower panel Pn+1 is moved upward from below the upper panel Pn by the hanging device 6. By moving the lower panel Pn+1 upward along the front surface of the base material 1 in this manner, the lower panel Pn+1 is moved to a connection position where its upper end is inserted into and connected to the lower end of the upper panel Pn, as shown in FIG. 2A.

When in the connected position, the convex portion 12 of the upper panel Pn fits into the concave portion 15 of the lower panel Pn+1, the cover portion 11 of the upper panel Pn fits into the concave step portion 14 of the lower panel Pn+1, and the second cover portion 13 of the upper panel Pn fits into the space behind the concave portion 15 of the lower panel Pn+1. At this time, the cover portion 11 of the upper panel Pn is positioned in front of the long plate portion 210 of the first mounting member 21, covering and concealing the long plate portion 210.

(3-2) Second Step In the second step, the upper end of the lower panel Pn+1 in the connection position is fixed to the base material 1 while the lower panel Pn+1 is supported by the panel support 7.

In more detail, first, as shown in FIG. 2B, the hook portion 220 of the second mounting member 22 is fixed to the base material 1 by a pair of fasteners 24. Next, the pair of nuts 230 are rotated from the temporary fastening position to the fastening position to fasten (tighten). As a result, the upper end portion of the lower panel Pn+1 is fixed to the base material 1.

(3-3) Third Step In the third step, the panel support 7 is removed from the lower panel Pn+1. After the panel support 7 is removed, the lower panel Pn+1 is supported by the base material 1 alone.

After carrying out the first, second, and third steps described above, panels P1, P2, and P3 are attached to the base material 1 as shown in Figures 3A and 3B by carrying out the first, second, and third steps described above with panel P2 as the upper panel Pn and panel P3 as the lower panel Pn+1.

In other words, in the panel mounting method of this embodiment, the above-mentioned first, second, and third steps are repeated in this order to mount multiple panels P1, P2, P3, ... on the base material 1. The multiple panels P1, P2, P3, ... are mounted in a state where the ends of two panels that are adjacent to each other vertically are connected to each other. Furthermore, when the multiple panels P1, P2, P3, ... are mounted on the base material 1, the surfaces facing the front are flush with each other.

(4) Exterior Wall Structure Next, an example of an exterior wall structure 2 formed by a plurality of panels P1, P2, P3, . . . attached to a base material 1 will be described.

As shown in Figures 8A and 8B, in the exterior wall structure 2, each of the multiple panels (in this embodiment, panels P1 to P6) is fixed to the base material 1 via mounting fixtures 9. The top panel P1 may be fixed to the base material 1 with a fastener such as a screw.

The base material 1 further includes a base 100 made of a square pipe with its longitudinal direction extending left-right. The base 100 is placed on the foundation 101 of the building.

The exterior wall structure 2 further includes a support member 102 fixed to the base 100, a drainage member 103 fixed to the base 100, and a fastener 104 that fixes the support member 102 and the drainage member 103 to the base 100.

Multiple panels P1 to P6 are attached to the base material 1 in order from the top. After the bottom panel P6 is attached, a support member 102 and a drainage member 103 are fixed to the base 100 by a fixing device 104. The convex portion 12 of the panel P6 is placed on the support member 102. The support member 102 is provided with a stopper 105 that fits between the cover portion 11 and the convex portion 12 of the panel P6. The load of the panel P6 is supported by the mounting device 9 and the support member 102.

(5) Action and effect In the panel mounting method of this embodiment described above, by repeating the first step, the second step, and the third step in this order, multiple panels P1, P2, P3, ... can be mounted on the base material 1 in order from the top.

In addition, in the panel mounting method of this embodiment, the lower panel Pn+1 is suspended and supported from below by a panel support 7 that supports the panel from below so that its upper end is exposed, so that the panel support 7 does not get in the way when the lower panel Pn+1 is moved to the connection position or when the lower panel Pn+1 in the connection position is fixed to the base material 1.

Therefore, in the panel mounting method of this embodiment, the lower panel Pn+1 can be moved to the connection position and fixed to the base material 1 while being suspended, eliminating the need for the installer to manually support the weight of the lower panel Pn+1, thereby reducing the burden on the installer.

In addition, in the panel mounting method of this embodiment, the first mounting member 21 that penetrates the lower panel Pn+1 from the groove portion 16 toward the base material 1 is covered from the front side by the cover portion 11 of the upper panel Pn, thereby reducing exposure of the first mounting member 21 and ensuring waterproofing.

In addition, the panel support 7 of this embodiment supports the lower panel Pn+1 from below, and the upper end of the lower panel Pn+1 can also be supported by the upper support member 75, so the lower panel Pn+1 can be stably suspended and supported. In addition, since the upper support member 75 is detachable, it can be removed when not needed and does not get in the way when, for example, moving the lower panel Pn+1 to the connection position.

In addition, in the panel mounting method of this embodiment, the posture of the lower panel Pn+1 can be controlled from the indoor side (rear side) using tension members 77, etc., and the lower panel Pn+1 can be fixed to the base material 1 from the indoor side (rear side). Therefore, in the panel mounting method of this embodiment, it is not necessary to set up temporary scaffolding outside (in front of the lower panel Pn+1), and it is also not necessary to arrange for a contractor for high-altitude work, which reduces costs and enables construction in narrow areas where it is difficult to set up temporary scaffolding.

(6) Modifications Next, modifications of the above-mentioned panel mounting method will be described.

The panel installation method is not limited to exterior wall construction, but can also be used for interior wall construction.

The mounting device 9 is not limited to the above-mentioned structure and can be modified as appropriate. For example, the first mounting member 21 may not have the long plate portion 210 and may be composed of only a pair of bolts 211. Alternatively, as shown in the modified example of FIG. 9, the mounting device 9 may have a first mounting member 21 with only one bolt 211, and a second mounting member 22 with an L-shaped hook portion 220 in a plan view and one insertion portion 221.

The multiple panels P1, P2, P3, ... do not have to be the same in shape, size, or material. For example, panel P1 does not have to have a connection structure (recessed step portion 14, recessed portion 15, and grooved streak portion 16) at the upper end. In addition, the multiple panels P1, P2, P3, ... may have different lengths in the up-down direction.

The method of fixing the upper end of the lower panel Pn+1 at the connection position to the base material 1 is not limited to the method using the mounting fixture 9, and other methods may be used. For example, a drill screw may be driven into the base material 1 from the rear side, and the upper end of the lower panel Pn+1 may be fixed to the base material 1 by this drill screw.

(7) Summary Like the panel mounting methods of the embodiment and its modified examples described above, the panel mounting method of the first aspect has the following features.
