Description

The present invention relates to a panel fixing member for fixing an exterior wall panel, a portion of which has been cut to fit the dimensions of the exterior wall edge, to the exterior wall base plate at the exterior wall edge, and to an exterior wall panel fixing structure and an exterior wall panel fixing method using the panel fixing member.

Conventionally, in a structure in which an exterior wall surface is formed by arranging and attaching multiple exterior wall panels to an exterior wall base plate, the exterior wall panels are joined together using a joint joint or a real joint so that the joints are not exposed to the outside. The exterior wall panels are attached to the exterior wall base plate using a mounting bracket that is composed of a base plate fixed to the exterior wall base plate, a bent portion that is bent so as to be perpendicular to the horizontal direction of the base plate, and a locking portion formed at the tip of the bent portion, as shown in Patent Document 1, for example. This mounting bracket has a locking portion whose tip is bent into an arc shape that locks the male part of the exterior wall panel in a recess formed on its underside and locks the female part of the exterior wall panel in a protrusion formed on its upper surface, thereby attaching the exterior wall panel to the exterior wall base plate without exposing the mounting bracket to the outside.

The above-mentioned mounting hardware uses the shape of the joints formed at the top and bottom of the exterior wall panel to attach the exterior wall panel to the exterior wall base plate, so if the top and bottom ends of the exterior wall panel are cut to match the dimensions of the top or bottom of a window, for example, the mounting hardware cannot be used to attach the exterior wall panel. Therefore, a mounting hardware has been proposed that forms a locking hole in the cut edge of the exterior wall panel using a drill or the like, and is composed of a clip hardware with an insertion part that is inserted into the locking hole and locked, and a clip receiving hardware with a drop hole that is fixed to the base material and receives part of the clip hardware.

JP 2012-62635 A

The mounting hardware in Patent Document 1 drills locking holes in the cut edge, so depending on the thickness of the exterior wall panel, the strength of the cut edge may be weakened. Also, in order to insert the clip hardware into the clip receiving hardware, high construction precision is required for the position of the locking holes and the mounting position of the clip receiving hardware on the exterior wall base plate. And because the clip hardware is inserted into the clip receiving hardware, it cannot tolerate any shaking of the exterior wall panel in the horizontal direction relative to the exterior wall base plate, and it cannot absorb the load applied to the exterior wall panel in the event of an earthquake, for example, which makes the exterior wall panel prone to damage.

The present invention aims to provide a panel fixing member, an exterior wall panel fixing structure, and an exterior wall panel fixing method that do not require further processing of the cut edge, allow adjustment of the position of the exterior wall panel, and easily absorb loads in the horizontal plane.

The following describes an embodiment of the panel fixing member 1, exterior wall panel fixing structure 2, and exterior wall panel fixing method of the present invention with reference to the drawings. As shown in FIG. 1, the panel fixing member 1 in this embodiment is a metal fitting that fixes an edge exterior wall panel 4 that is placed on the edge of an exterior wall to an exterior wall base plate 3. Note that the edge exterior wall panel 4 is not limited to being made of ceramic, and may be, for example, an exterior wall panel that is a ceramic siding material.

The edge exterior wall panel 4 is formed by cutting a part of a general exterior wall panel. First, the general exterior wall panel 5 will be described. The general exterior wall panel 5 is formed in a rectangle that is long in the horizontal direction and short in the vertical direction, with a decorative pattern of bumps on the front surface and a flat back surface. The upper end of the general exterior wall panel 5 is formed with an upper end tongue 6 that protrudes upward on the back surface side, and the front surface side is formed to be lower than the back surface side. In addition, the lower end of the general exterior wall panel 5 is formed with a lower end tongue 7 that protrudes downward on the front surface side, and a back tongue 8 is formed on the back surface side that is shorter than the front surface side and protrudes downward, and a lower end groove 9 is formed between the lower end tongue 7 and the back tongue 8.

A hollow portion 10 is formed inside the general exterior wall panel 5. The hollow portion 10 is a hole formed along the width direction of the general exterior wall panel 5, and in this embodiment is a plurality of parallel horizontal holes with a circular or elongated cross-sectional shape.

The general exterior wall panel 5 is arranged on the outdoor side of the exterior wall base plate 3 fixed to the structural body of the building (not shown) to form the exterior wall surface.

The general exterior wall panel 5 is formed, for example, to be about 300 mm in the height direction, about 1500 mm in the width direction, and about 18.5 mm in thickness. The length in the width direction varies depending on the position where the general exterior wall panel 5 is installed. The general exterior wall panels 5 are arranged in a row in the height direction and width direction. In this embodiment, an opening 12 for a waist window is arranged on the exterior wall surface. The general exterior wall panels 5 arranged on both sides of the opening 12 are formed to be about 240 mm wide. The opening 12 is formed to be about 1000 mm wide and about 700 mm high.

As shown in FIG. 3, the general exterior wall panel 5, which is about 300 mm in height, cannot be fitted to the upper and lower parts of the opening 12, so an edge exterior wall panel 4 is placed by cutting the general exterior wall panel 5 to fit the dimensions of the upper and lower parts of the opening 12. The edge exterior wall panel 4 is formed by cutting the general exterior wall panel 5 so that the opening 12 side is the cut surface, as shown in FIG. 4. That is, at the upper part of the opening 12, the lower part of the general exterior wall panel 5 is cut off to form the edge exterior wall panel 4, and at the lower part of the opening 12, the upper part of the general exterior wall panel 5 is cut off to form the edge exterior wall panel 4. The edge exterior wall panel 4 has an insertion hole 23 drilled from the back surface to one hollow part 10, allowing the panel fixing member 1 described later to be attached.

As shown in Figures 5 to 7, the panel fixing member 1 for fixing the edge exterior wall panel 4 to the exterior wall base plate 3 includes a backside fixing device 13 fixed to the backside of the edge exterior wall panel 4, and a base side fixing device 14 fixed to the exterior wall base plate 3 and connected to the backside fixing device 13. The backside fixing device 13 has a main body 15 that abuts against the backside of the edge exterior wall panel 4, and an insertion portion 16 whose base end 16a is fixed to the main body 15 and whose tip 16b is bent and inserted into an insertion hole 23 formed in the hollow portion 10 from the backside of the edge exterior wall panel 4, and whose tip 16b is hooked and engaged in the hollow portion 10.

5, the main body 15 has a fixed body 17 fixed to the back surface of the edge exterior wall panel 4 and having a U-shaped horizontal cross section, and a protruding portion 18 formed on a flat plate on the side of the fixed body 17, the tip of which protrudes from the edge of the edge exterior wall panel 4. The fixed body 17 has one end abutting the back surface of the edge exterior wall panel 4 and the other end extending in a direction away from the back surface of the edge exterior wall panel 4, and is composed of a pair of parallel side plates 17a formed along the vertical direction, and a back plate 17b connecting the other ends of the pair of side plates 17a. A long hole 17c extending in the vertical direction is formed in the back plate 17b. The protrusion 18 is formed along the back surface of the edge exterior wall panel 4 from one end of one side plate 17a of the fixing body 17 that abuts against the back surface of the edge exterior wall panel 4, and its tip protrudes from the edge of the edge exterior wall panel 4 toward the side where the opening 12 is formed. The protrusion 18 has a connection hole 18a formed at its protruding tip for connection to the base side fixing device 14 fixed to the exterior wall base plate 3. The connection hole 18a is formed as a long hole that is long in the horizontal direction.

As shown in FIG. 6, the insertion portion 16 has a base end 16a formed in a square plate shape and an insertion portion 16c extending from the base end 16a with a bent tip 16b. The base end 16a has a screw hole 16d into which a fixing bolt 19 is screwed and inserted into a long hole 17c formed in the back plate 17b of the fixing body 17 of the main body 15. The screw hole 16d is formed by crimping or welding a nut to a through hole formed in the base end 16a. The insertion portion 16 extends from the base end 16a toward the back surface of the exterior wall panel to form the insertion portion 16c, and the tip 16b is in the in-plane direction of the edge exterior wall panel 4 and is bent in a horizontal direction. The insertion portion 16c is inserted into an insertion hole 23 formed in the edge exterior wall panel 4, and the bent tip 16b is hooked into the hollow portion 10 of the edge exterior wall panel 4. With the tip 16b of the insertion portion 16 hooked into the hollow portion 10 of the edge exterior wall panel 4, the fixing bolt 19 inserted into the long hole 17c of the fixing body 17 screws into the screw hole 16d of the base end 16a, and the insertion portion 16 is moved in a direction approaching the back plate 17b of the fixing body 17, so that the edge exterior wall panel 4 is sandwiched between the tip 16b of the insertion portion 16 and the side plate 17a of the fixing portion, and the back side fixing device 13 is fixed to the back surface of the edge exterior wall panel 4.

As shown in FIG. 7, the base fixing device 14 has a flat base fixing part 14a with two screw insertion holes 14c formed to be fixed to the exterior wall base plate 3, and a connecting part 14b formed to protrude from one side of the base fixing part 14a toward the outside and connected to the back side fixing device 13. The base fixing part 14a is fixed to the exterior wall base plate 3 by inserting fixing screws 14d into the two screw insertion holes 14c in a rectangular flat shape and driving the fixing screws 14d into the exterior wall base plate 3. The connecting part 14b is formed in a U-shape when viewed from above, and has two parallel side panels 14e and a connecting plate 14f connecting the two side panels 14e. The two side panels 14e are formed with a cut so that the lower part abuts the exterior wall base plate 3 and the upper part is separated from the exterior wall base plate 3. The connecting plate 14f is formed away from the exterior wall base plate 3, and has a connecting screw hole 14g formed at the top into which a connecting bolt 14h can be screwed. The connecting screw hole 14g connects the rear fixing device 13 and the base fixing device 14 to each other by screwing the connecting bolt 14h inserted into the connecting hole 18a formed in the protruding portion 18 of the rear fixing device 13.

The exterior wall panel fixing structure 2 for fixing the edge exterior wall panel 4 arranged at the bottom of the opening 12 is an exterior wall panel fixing structure 2 that uses the above-mentioned panel fixing member 1 to fix the edge exterior wall panel 4 to the margin 20 that is formed between the opening 12 and the general exterior wall panel 5 and has a height length shorter than the height dimension of the general exterior wall panel 5 when the general exterior wall panel 5 is fixed using the fixing hardware 11 in sequence from the lower end of the exterior wall, as shown in Figures 1 and 8. The back tongue 8 formed at the lower end of the edge exterior wall panel 4 is engaged and fixed to the fixing hardware 11 that is screwed to the exterior wall base plate 3, and the edge exterior wall panel 4 is fixed to the margin 20 by connecting the back side fixing tool 13 fixed to the back side of the edge exterior wall panel 4 and the base side fixing tool 14 fixed to the exterior wall base plate 3 with a connecting bolt 14h.

The exterior wall panel fixing structure 2 for fixing the edge exterior wall panel 4 arranged above the opening 12 is an exterior wall panel fixing structure 2 for fixing the edge exterior wall panel 4 to the margin 20 formed between the general exterior wall panel 5 arranged above the opening 12 and the opening 12 using a panel fixing member 1, as shown in Figures 1 and 9. The upper end tongue 6 formed at the upper end of the edge exterior wall panel 4 is engaged and fixed to the fixing hardware 11 fixed to the exterior wall base plate 3 with a screw, and the edge exterior wall panel 4 is fixed to the margin 20 by connecting the back side fixing device 13 fixed to the back side of the edge exterior wall panel 4 and the base side fixing device 14 fixed to the exterior wall base plate 3 with a connecting bolt 14h.

The exterior wall panel fixing structure 2 is not limited to fixing the edge exterior wall panel 4 to the upper or lower part of the opening 12. The exterior wall panel fixing structure 2 can be used when the height of the exterior wall is not a multiple of the general exterior wall panel 5, such as when a part of the exterior wall protrudes toward the outdoors, such as the waist wall of a balcony or the overhanging part of a building, and when the general exterior wall panels 5 are arranged in a line in the height direction, a blank area 20 is generated where the general exterior wall panel 5 cannot be placed.

As shown in Figure 10, the exterior wall panel fixing method for constructing the exterior wall panel fixing structure 2 as described above involves first fixing the exterior wall base plate 3 to the structural body of the building, forming an opening 12 where the exterior wall base plate 3 is not provided, and fixing a sash frame 21 and the like to the opening 12. The sash frame 21 has fins 22 fixed to the surface of the exterior wall base plate 3 at the top and bottom to maintain airtightness and waterproofing with the exterior wall base plate 3. Once the exterior wall base plate 3 is fixed, the fixing hardware 11 is then screwed to the exterior wall base plate 3 with screws 25 starting from the bottom end, the back tongue 8 formed at the bottom end of the general exterior wall panel 5 is engaged with the fixing hardware 11, and then the fixing hardware 11 is fitted into the upper end tongue 6 and the fixing hardware 11 is screwed to the exterior wall base plate 3. The lowest fixing hardware 11 is not shown, but since it does not need to lock the upper end tongue 6, it only needs to be shaped to lock the back tongue 8.

Then, after the general exterior wall panel 5 is fixed below the opening 12, leaving the margin 20 formed at the bottom of the opening 12, the edge exterior wall panel 4 is attached. The process of attaching the edge exterior wall panel 4 begins with a cutting process in which the general exterior wall panel 5 is cut in advance at a factory to fit the size of the margin 20, as shown in FIG. 11. Specifically, the edge exterior wall panel 4 formed at the top of the opening 12 has the lower part of the general exterior wall panel 5 cut off to fit the size of the margin 20, and the edge exterior wall panel 4 formed at the bottom of the opening 12 has the upper part of the general exterior wall panel 5 cut off to fit the size of the margin 20. As a result, the edge exterior wall panel 4 has an upper end tongue 6 or a lower end tongue 7 and a back tongue 8 formed at the end of the edge exterior wall panel 4 on the general exterior wall panel 5 side, and the general exterior wall panel 5 can be fixed with a general fixing hardware 11 that fixes it to the exterior wall base plate 3, and a cut surface is formed at the end of the edge exterior wall panel 4 on the opening 12 side. Next, as shown in FIG. 12, an insertion hole forming process is performed on the back surface of the edge exterior wall panel 4, in which an insertion hole 23 is drilled from the back surface to the hollow portion 10 at a position where the tip 16b of the insertion portion 16 will be inserted when the back fixing device 13 is fixed to the edge exterior wall panel 4. The insertion hole 23 is formed at a position where the hollow portion 10 exists in the height direction of the edge exterior wall panel 4. From the viewpoint of processing accuracy and simplification of on-site construction, it is preferable to perform these cutting process and insertion hole forming process at a factory to form the edge exterior wall panel 4 and then transport it to the construction site, but the cutting process and insertion hole forming process may also be performed at the construction site.

When the edge exterior wall panel 4 is transported to the construction site, a backside fastener attachment process is performed to attach the backside fastener 13 to the edge exterior wall panel 4, as shown in Figures 13 and 14. In this process, the backside fastener 13 is arranged so that a part of the protrusion 18 protrudes from the upper end or lower end of the edge exterior wall panel 4 and the connection hole 18a is exposed to the outside, and is fixed to the edge exterior wall panel 4. Specifically, the tip 16b of the insertion part 16 of the backside fastener 13 is inserted into the insertion hole 23 formed on the back surface of the edge exterior wall panel 4, and the fixing bolt 19 inserted into the long hole 17c formed in the main body 15 of the backside fastener 13 is screwed into the screw hole 16d of the base end 16a of the insertion part 16 and tightened, thereby fixing the backside fastener 13 and the edge exterior wall panel 4. At this time, the height position of the rear fixing device 13 is adjusted by adjusting the relative position of the fixing bolt 19 within the long hole 17c, and the position where the connection hole 18a of the protrusion 18 of the rear fixing device 13 is formed is positioned so that it protrudes from the upper or lower end of the edge exterior wall panel 4, and the protrusion 18 is positioned so that it does not interfere with the sash frame 21 of the opening 12.

In addition, before inserting the tip 16b of the insertion portion 16 into the insertion hole 23 of the edge exterior wall panel 4, adhesive may be applied to the insertion hole 23 or the tip 16b of the insertion portion 16, and then the tip 16b of the insertion portion 16 is inserted into the insertion hole 23 and glued in place. In this way, the insertion portion 16 is more firmly fixed to the insertion hole 23. At this time, it is preferable that the adhesive is applied so as to completely seal the gap between the insertion hole 23 and the tip 16b of the insertion portion 16. This configuration can prevent water from entering the insertion hole 23.

Next, as shown in FIG. 15, a fixing screw 14d is inserted into the screw insertion hole 14c formed in the base fixing portion 14a of the base fixing device 14 and driven into the exterior wall base plate 3 to perform a base fixing device installation process in which the base fixing device 14 is fixed to the exterior wall base plate 3. The base fixing device 14 is installed in a position where the connecting screw hole 14g formed in the connecting portion 14b of the base fixing device 14 is aligned with the position where the connecting hole 18a of the back fixing device 13 is located when the edge exterior wall panel 4 is placed.

After the base fixing device 14 is fixed to the exterior wall base plate 3, as shown in FIG. 16, the lower end of the edge exterior wall panel 4 located at the bottom of the opening 12 is fitted into a fixing bracket provided at a position where it can be butted against the general exterior wall panel 5, and a connecting process is performed in which a connecting bolt 14h is inserted from the connecting hole 18a of the back side fixing device 13 and screwed into the connecting screw hole 14g of the base side fixing device 14 to connect the back side fixing device 13 and the base side fixing device 14, and the edge exterior wall panel 4 is fixed to the exterior wall base plate 3. Then, a back side fixing device installation process is performed in which the back side fixing device 13 is also attached to the edge exterior wall panel 4 located at the top of the opening 12. After that, a connecting bolt 14h is inserted from the connecting hole 18a of the back side fixing device 13 and screwed into the connecting screw hole 14g of the base side fixing device 14 to connect and fix the back side fixing device 13 and the base side fixing device 14. Then, a fixing hardware 11 is fitted into the upper end tongue 6 of the exterior wall panel 4 at the upper edge of the opening 12, and the fixing hardware 11 is screwed to the exterior wall base plate 3, performing a connecting process to fix the exterior wall panel 4 at the upper edge of the opening 12 to the exterior wall base plate 3.

When fixing the edge exterior wall panels 4 above and below the opening 12 to the exterior wall base plate 3 in this way, the connecting hole 18a is a long hole that is long horizontally, so the connecting process can be performed while adjusting the horizontal position of the edge exterior wall panel 4. In addition, since the connection between the back side fixing device 13 and the base side fixing device 14 is pin-jointed by the connecting bolt 14h, even if a horizontal external force is applied due to an earthquake, for example, the edge exterior wall panel 4 can be allowed to sway slightly, and damage to the edge exterior wall panel 4 can be suppressed.

After completing the connecting process, the back tongue 8 formed at the lower end of the general exterior wall panel 5 is engaged with the fixing hardware 11 that is fitted into the upper end tongue 6 of the edge exterior wall panel 4 above the opening 12 and screwed to the exterior wall base plate 3, and then another fixing hardware 11 is fitted into the upper end tongue 6 of the general exterior wall panel 5 and screwed to the exterior wall base plate 3.
