JP 2019-065503 A

Incidentally, in the wall unit described in Patent Document 1, no trim material is provided on the exterior side of the structure, but there are cases where such a trim material is used to facilitate exterior wall finishing. In this case, for example, if the trim material is attached directly to the structure, there is a high risk that rainwater and the like will infiltrate the structure through this attachment part. In addition, there is a risk that the effort required for waterproofing treatment to reduce the risk of rainwater and the like infiltrating the structure through the attachment part will increase.

The object of the present invention is to provide a trim mounting structure that can prevent rainwater and other water from entering the structure and reduce the effort required for waterproofing treatment.

The trim mounting structure of the present invention is characterized in that a sash is installed in an opening of a frame on which an exterior wall material is installed on the outside of the room, the sash has a sash frame that is positioned on the inside of the room relative to the exterior wall material, and a sash body that is positioned within the sash frame, and the trim material is attached to the sash frame.

The present invention provides a trim mounting structure that can prevent rainwater and other water from entering the structure and reduce the effort required for waterproofing treatment.

[Configuration of this embodiment]
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
1 to 5, an assembled panel 1 constituting a trim mounting structure 10 according to this embodiment is incorporated into a building to form its wall, and includes a panel body 2 and an opening frame 5 which forms an opening 4 in which a sash 3 is placed relative to the panel body 2. The panel body 2 constitutes part of the building's framework when incorporated into the building, and an exterior wall material 7 is installed via a spacer 6 at a position on the outdoor side of the panel body 2.
In the following description, the left-right direction of the assembled panel 1 is defined as the X-axis direction, the up-down direction of the assembled panel 1 is defined as the Y-axis direction, and the projection direction (indoor/outdoor direction) of the assembled panel 1 is defined as the Z-axis direction. The X, Y, and Z axes are perpendicular to each other. Note that Fig. 1 shows the external appearance of the assembled panel 1 with the exterior wall material 7, spacers 6, and panels 25 omitted.

1 to 3, the panel body 2 comprises a frame 23 having left and right vertical members 21 and upper and lower horizontal members 22, and a panel 25 arranged within the frame 23. The vertical members 21 and the horizontal members 22 are framed horizontally, and the panels 25 are installed in a space partitioned by the frame 23 above a lintel 51 (described later), and in a space partitioned below a window sill 52 (described later). A stud 26 is provided along the Y-axis direction at the midpoint in the X-axis direction between the left and right vertical members 21.
As shown in Figures 2 and 3, the panel 25 has a load-bearing surface material 251 such as particle board made by overlapping a plurality of wooden boards in this embodiment as a surface material that constitutes the exterior wall portion of the panel body 2.

The opening frame 5 is provided with upper and lower intermediate horizontal members along the X-axis direction, which are disposed between the upper and lower horizontal members 22 and have both ends connected to the left and right vertical members 21. In this embodiment, the upper intermediate horizontal member is composed of a lintel 51, and the lower intermediate horizontal member is composed of a window sill 52. The opening 4 is divided into the lintel 51 and the window sill 52 between the left and right vertical members 21. As shown in FIG. 3, the window sill 52 has a step 53 facing the outside of the room, and an attachment 11 is disposed on the step 53 to which a water dripping material 61 (described later) is attached by engaging with it. The attachment is screwed to the inner peripheral surface located on the inside of the room from the step 53 of the window sill 52.

In this embodiment, the sash 3 is configured as an inward-opening window, and includes a shoji screen 31 as the sash body, and a window frame 32 as a sash frame arranged around the shoji screen 31. The shoji screen 31 is configured by assembling an upper frame 311, a lower frame 312, left and right vertical frames 313, and a surface material 314 such as a glass panel. The window frame 32 is configured by framing an upper frame 33, a lower frame 34, and left and right vertical frames 35, and the lower frame 34 is placed on a window sill 52. A handle 41 is attached to the vertical frame 313 on the door end side, and the vertical frame 313 on the hanging side is connected to the adjacent vertical frame 35 via a hinge 42 (axis) so that the shoji screen 31 can be opened inward.

In this embodiment, the upper frame 33, the lower frame 34 and the left and right vertical frames 35 are extrusion-molded from a common resin profile 30, and each has the same frame shape as the others.
As shown in Figures 4 and 5, the shaped member 30 is formed into a hollow shape with an exterior facing surface 301, an interior facing surface 302, an outer peripheral facing surface 303, and an inner peripheral facing surface 304. A doorstop 305 is formed between the exterior facing surface 301 and the inner peripheral facing surface 304 so as to protrude toward the inner peripheral side, and an airtight material 305A is attached to the doorstop 305, which abuts against the paper screen 31 when the sash 3 is closed. A plurality of partition pieces 306 are provided in the hollow portion 300 of the shaped member 30, and the hollow portion 300 is divided into a plurality of spaces 307 by the plurality of partition pieces 306. Here, the shaft portion of the fixing screw 8 for fixing the trim members 45A and 45B described later is disposed in the space 307A (drainage hollow portion) located on the outdoor side among the multiple spaces 307, and even if water such as rainwater enters the space 307A from the screwed portion of the fixing screw 8 to the shaped member 30, this water flows through the space 307A and is drained to the outdoor side. In other words, even if rainwater enters the space 307A of the upper frame 33 or the vertical frame 35, this rainwater flows down in the space 307A and is drained to the outdoor side space from a drain hole (not shown) formed in the lower frame 34. Therefore, water is prevented from entering the indoor space through the hollow portion 300 of the shaped member 30. The partition piece 306 also increases the strength of the shaped member 30.

As shown in FIG. 4, waterproof tape 9 is applied to the exterior-facing surface 301 of the upper frame 33 and the exterior-facing surface (surface) of the adjacent load-bearing surface material 251. The waterproof tape 9 is applied across the upper frame 33 and the load-bearing surface material 251, sealing the gap between the upper frame 33 and the load-bearing surface material 251 from the outside of the room, thereby forming a waterproof structure on the outside of the room. Meanwhile, a lining 308 is applied between the interior part of the upper frame 33 and the opposing part of the lintel 51, thereby bonding the interior part of the upper frame 33 and the opposing part of the lintel 51 together and sealing the gap between them, thereby forming a waterproof structure on the interior side.

Waterproof tape 9 is affixed to the exterior-facing surface 301 of the vertical frame 35 and the exterior-facing surface (front surface) of the adjacent load-bearing surface material 251. The waterproof tape 9 is affixed across the vertical frame 35 and the load-bearing surface material 251, thereby sealing the gap between the vertical frame 35 and the load-bearing surface material 251 from the outside of the room, thereby forming a waterproof structure on the outside. Meanwhile, a lining 308 is applied between the interior part of the vertical frame 35 and the part of the vertical member 21 facing it, thereby bonding the interior part of the vertical frame 35 and the part of the vertical member 21 facing it and sealing the gap between them, thereby forming a waterproof structure on the interior side.
In addition, a mounting bracket 37 is screwed to the outer peripheral visible surface portion 303 of the vertical frame 35, and the vertical frame 35 is attached to the vertical member 21 by screwing this mounting bracket 37 to the vertical member 21 with screws 371.
In addition, the lining 308 is also applied between the lower frame 34 and the portion of the window sill 52 facing it.

Partitioning materials 45A, 45B (wall parting materials) are attached to three sides of the aforementioned upper frame 33 and the left and right vertical frames 35, with the parting material 45A being screwed to the upper frame 33 with fixing screws 8, and the parting material 45B being screwed to the left and right vertical frames 35 with fixing screws 8, respectively.
The trim material 45A has a fixing piece 46A along the exterior appearance surface 301 of the upper frame 33 and a trim piece 47A extending from the fixing piece 46A to the exterior, and is formed in a substantially L-shaped cross section. The trim piece 47A has a screw hole 471, to which the left and right trim materials 45B are screwed. The fixing piece 46A is fixed to the exterior appearance surface 301 of the upper frame 33 by inserting a fixing screw 8, and is disposed at a position above the position of the trim piece 47A (at a position on the outer periphery of the upper frame 33). The fixing piece 46A is disposed so as to overlap the waterproof tape 9 from the exterior side. The fixing screw 8 is screwed into the partition piece 306 (frame portion partitioning the space 307A) adjacent to the exterior appearance surface 301 in the Z-axis direction. Furthermore, a sealing material 71 and a backup material 72 are applied at a position between the exterior wall material 7 and the parting piece portion 47A and facing the fixed piece portion 46A in the Z-axis direction.
The trim material 45B has a fixing piece 46B along the exterior appearance surface 301 of the vertical frame 35 and a parting piece 47B extending from the fixing piece 46B to the exterior side, and is formed in a substantially L-shaped cross section. The fixing piece 46B is fixed to the exterior appearance surface 301 of the vertical frame 35 by inserting a fixing screw 8, and is located at a position on the outer periphery side of the vertical frame 35 from the position of the parting piece 47B. This fixing piece 46B is arranged to overlap the waterproof tape 9 from the exterior side. The fixing screw 8 is screwed into the exterior appearance surface 301 and the partition piece 306 (frame part partitioning the space 307A) adjacent to it in the Z-axis direction. In addition, a seal material 71 and a backup material 72 are applied between the exterior wall material 7 and the parting piece 47B and at a position facing the fixing piece 46B in the Z-axis direction. The upper end of the parting material 45B is screwed into the screw hole 471 of the parting piece portion 47A. The lower end of the parting material 45B is disposed opposite the water-repellent material 61. In other words, the lower end of the parting material 45B is disposed on the water-repellent material 61.
The above-mentioned trim materials 45A, 45B separate the exterior wall material 7.
In this manner, in this embodiment, the trim material mounting structure 10 is formed by attaching the trim materials 45A, 45B to the upper frame 33 and the left and right vertical frames 35.

As described above, the attachment 11 installed on the step 53 of the window sill 52 has a water-repellent material 61 attached to it. The water-repellent material 61 extends from the attachment 11 to the outside of the room and also extends in the X-axis direction to a position more outer than the left-side trim material 45B and a position more outer than the right-side trim material 45B, with the lower ends of the left and right trim materials 45B resting on the top of the water-repellent material 61. Caps 62 are attached to both ends of the water-repellent material 61 in the X-axis direction.

When transporting the assembled panels 1, the assembled panels 1 are stacked flat without the trims 45A, 45B or the drainage material 61 attached. At this time, the panels can be easily stacked flat because there are no trims 45A, 45B or drainage material 61 protruding from the opening 4 in the Z-axis direction that would interfere with stacking.

When constructing the assembled panel 1 on-site, the trim members 45A, 45B and the water-repellent member 61 are attached as follows. The waterproof tape 9 is attached in advance across the exterior appearance surface portion 301 of the top frame 33 and the left and right vertical frames 35 and the surface of the load-bearing surface member 251, the lining 308 is applied between the top frame 33, the bottom frame 34, the left and right vertical frames 35 and the lintel 51, the window sill 52 and the left and right vertical members 21, and the attachment 11 is attached to the window sill 52.
The water cutting material 61 is attached by engaging it with the attachment 11.
To attach the left and right trim members 45B, first the fixing pieces 46B are overlapped with the waterproof tape 9 from the outside of the room, and then the fixing pieces 46B are screwed and fixed to the exterior facing surfaces 301 of the left and right vertical frames 35 by the fixing screws 8. The shafts of the fixing screws 8 screwed into the exterior facing surfaces 301 of the vertical frames 35 are disposed in the spaces 307A within the vertical frames 35.
To attach the parting material 45A, after the left and right parting materials 45B are attached, the fixing piece 46A is overlapped with the waterproof tape 9 from the outside of the room, and then the fixing piece 46A is screwed and fixed to the exterior facing surface 301 of the upper frame 33 by the fixing screw 8. The shaft of the fixing screw 8 screwed into the exterior facing surface 301 of the upper frame 33 is disposed in the space 307A within the upper frame 33.
In addition, the left and right trim members 45B are screwed into the screw holes 471 of the trim member 45A, thereby forming a U-shaped trim member that extends along three sides of the upper frame 33 and the left and right vertical frames 35 as a whole.
An exterior wall material 7 is installed on the outdoor side of the assembled panel 1 via a spacer 6, and a sealing material 71 and a backup material 72 are provided between the exterior wall material 7 and the trim materials 45A, 45B and the water drainage material 61.
In this way, the trim members 45A, 45B are attached to the window frame 32, not to the load-bearing surface material 251 side (frame side), so that a screw-driving portion for attaching the trim members 45A, 45B is formed on the frame side, eliminating the risk of rainwater and the like penetrating into the frame from this portion, and also eliminating the need to provide a separate waterproof sheet to cover the screw-driving portion to the frame from the outside after the trim members are attached. Note that, because the shanks of the fixing screws 8 that fix the trim members 45A, 45B to the exterior appearance surface portion 301 are positioned in the space 307A (drainage hollow portion), rainwater flows down and is drained to the outside without penetrating into the space on the indoor side of the assembled panel 1.

[Modification]
In the above embodiment, trim material 45A and left and right trim materials 45B are attached to three sides of the upper frame 33 and the left and right vertical frames 35, but if there are areas, for example, where it is not necessary to divide the exterior wall material 7, either the trim material 45A or the left and right trim materials 45B may be omitted.
In the above embodiment, the trim materials 45A, 45B are configured so that the fixing pieces 46A, 46B are positioned at a position closer to the outer periphery of the window frame 32 than the position of the trim pieces 47A, 47B, but this is not limited to the above and the fixing pieces 46A, 46B may be configured so that they are positioned at a position closer to the inner periphery of the window frame 32 than the position of the trim pieces 47A, 47B.
In the above embodiment, the fixing pieces 46A, 46B of the trim pieces 45A, 45B overlap the waterproof tape 9, but this is not limited thereto, and the fixing pieces 46A, 46B do not have to overlap the waterproof tape 9.
In the above embodiment, a space 307A serving as a hollow section for drainage is further formed in the hollow section 300 of the profile 30 by partitioning it with a partition piece 306, but if drainage is performed through the hollow section 300 of the profile 30 itself, it is not necessary to further partition and form the space 307A within the hollow section 300.
In the above embodiment, the trim members 45A, 45B are fixed to the window frame 32 with screws, but this is not limited thereto, and the trim members 45A, 45B may be glued to the window frame 32.
In the above embodiment, an inward-opening window is used as the sash 3, but other types of fittings such as a sliding window or a tilt-down window may also be used as the sash 3.

[Summary of the invention]
(1) The trim mounting structure of the present invention is characterized in that a sash is installed in an opening of a main body on which an exterior wall material is installed on the outside of the room, the sash has a sash frame that is positioned on the indoor side of the exterior wall material and a sash body that is positioned within the sash frame, and a trim material is attached to the sash frame.
According to the trim mounting structure of the present invention, for example, when a trim is mounted to a main body, if there is a defect in the water-stopping part due to deterioration or the like, there is a risk that rainwater etc. will infiltrate into the main body through the mounting part. However, in the present invention, the trim is mounted to the sash frame rather than to the main body, so that even if there is a defect in the water-stopping part due to deterioration or the like, it is possible to prevent the infiltration of rainwater etc. into the main body through the mounting part of the trim.
(2) In the trim mounting structure of the present invention, the sash frame has an upper frame, a lower frame and left and right vertical frames, and the trim may be mounted on three sides of the upper frame and the left and right vertical frames.
With this configuration, it is possible to avoid attaching trim materials to the upper and left and right positions on the main body, thereby eliminating the risk of rainwater, etc., penetrating into the main body through the attachment parts.
(3) In the trim mounting structure of the present invention, the trim has a fixed piece portion along the exterior facing surface portion of the sash frame and a trim piece portion extending from the fixed piece portion to the outside of the room, and the fixed piece portion may be fixed to the exterior facing surface portion of the sash frame.
With this configuration, the fixing piece portion of the trim material can be easily fixed to the exterior appearance surface portion of the sash frame facing the exterior side.
(4) In the trim mounting structure of the present invention, the fixing piece portion may be positioned on the outer periphery side of the sash frame relative to the trim piece portion.
With this configuration, after the exterior wall material is installed around the trim piece, the fixing piece is positioned between the sash frame and the exterior wall material, making the fixing piece inconspicuous in appearance.
(5) In the trim mounting structure of the present invention, a sealant may be applied to a position between the exterior wall material and the trim piece portion, facing the fixing piece portion in the prospective direction.
With this configuration, it is possible to prevent water from entering between the exterior wall material and the parting piece, and the sealing treatment between them prevents rainwater and the like from penetrating into the fixed piece, thereby improving water-stopping properties.
(6) In the trim mounting structure of the present invention, a waterproof tape may be provided spanning the main body and the sash frame, and the fixing piece portion may be positioned so as to overlap the waterproof tape from the outside of the room.
With this configuration, waterproof tape is laid in advance, and even when the trim material is attached at the construction site, there is no need to fix the fixing piece to the main body. Therefore, for example, by using fixing screws, the water-stopping properties of the main body are not reduced, and there is no need to lay further waterproof tape to cover the fixing piece, improving workability.
(7) In the trim mounting structure of the present invention, the sash frame has an upper frame, a lower frame and left and right vertical frames, the trim is attached to the upper frame and the left and right vertical frames, and a water drip material may be arranged opposite the lower ends of the trim attached to the left and right vertical frames.
With this configuration, rainwater running down the trim attached to the left and right vertical frames does not fall straight down from the bottom end of the trim, but is guided to the outside by the drip-water material, reducing the risk of the main body getting wet at a position below the drip-water material.
(8) In the trim mounting structure of the present invention, the sash frame may form a hollow portion for drainage on the outside of the room, and the trim may be fixed by a fastener to the frame portion of the sash frame that forms the hollow portion.
With this configuration, even if water such as rainwater seeps into the sash frame from the part where the trim material is fixed to the sash frame with a fixing device, the water can be limited to the hollow part for drainage, and the water can be prevented from seeping into the space inside the room.
