Embodiments of the present disclosure will be described in detail below with reference to the drawings. 1 to 4 show a shutter device 1 attached to the outdoor side of a window 120 attached to an opening 110 of a building frame 100. X1 shown in the figure indicates the outdoor side, and X2 indicates the indoor side. In this specification, in the shutter device 1, the surface disposed on the X1 side is defined as an outdoor finding surface, and the surface disposed on the X2 side is defined as an indoor finding surface.

As shown in FIGS. 2 and 3, the window 120 of this embodiment has two shoji 122, 122 housed inside a rectangular window frame 121 attached to the opening 110 so as to be slidable laterally. It is a sliding window. A screen door 123 is housed on the outdoor side of the shoji 122, 122 so as to be slidable laterally. In FIG. 4, the shoji 122 and the screen door 123 are omitted. This window 120 is attached separately from the shutter device 1 to an opening 110 facing a balcony on the second floor of the building.

An exterior material 131 is provided on the surface of the outer wall surface 130 around the opening 110. As shown in FIG. 1, the lower end 131a of the exterior material 131 does not reach the outer floor surface 140, which is the floor surface of the balcony, and is arranged slightly above the lower end of the window frame 121. A drainer 132 extending laterally is provided at the lower end 131a of the exterior material 131. No exterior material 131 is provided between the drainer 132 and the outer floor surface 140. Therefore, the outer wall surface 130 below the drainer 132 is recessed toward the indoor side with respect to the surface of the outer covering material 131 because the outer covering material 131 is not provided.

As shown in FIGS. 1 and 2, a waterproof layer 150 made of FRP (Fiber Reinforced Plastics) or the like is provided on the outdoor side of the building frame 100. The waterproof layer 150 has a floor section 151 provided on the outer floor surface 140 and a rising section 152 that is continuously raised from the floor section 151 along the outer wall surface 130 . The rising portion 152 covers the lower part of the outer wall surface 130 between the outer floor surface 140 and the drainer 132.

The shutter device 1 is attached to an outer wall surface 130 outside the window 120 attached to the opening 110. That is, the shutter device 1 of this embodiment is an opening shielding member for renovation that is retrofitted to the window 120, which is an existing window. The shutter device 1 includes a rectangular mounting frame 2, a shutter box 3 attached to the top of the mounting frame 2, and a pair of guide rails 4, 4.

As shown in FIG. 4, the mounting frame 2 of this embodiment is composed of a base frame 21 and a shutter frame 22.

The base frame 21 is formed by framing an upper frame 211, a lower frame 212, and a pair of left and right vertical frames 213, 213 into a rectangular shape. Slightly below the upper frame 211, an intermediate frame 214 extending between the left and right vertical frames 213, 213 is provided in parallel to the upper frame 211 and the lower frame 212. The upper frame 211, the lower frame 212, the vertical frames 213, 213, and the intermediate frame 214 are all constructed of extrusion molded materials using a metal material such as aluminum.

The shutter frame 22 is formed by framing an upper frame 221, a lower frame 222, and a pair of left and right vertical frames 223, 223 into a rectangular shape. Slightly below the upper frame 221, an intermediate frame 224 extending between the left and right vertical frames 223, 223 is provided in parallel to the upper frame 221 and the lower frame 222. The upper frame 221, the lower frame 222, the vertical frames 223, 223, and the intermediate frame 224 are all constructed of extrusion molded materials using a metal material such as aluminum.

The vertical and horizontal sizes of the shutter frame 22 are approximately equal to the vertical and horizontal sizes of the base frame 21. The shutter frame 22 is integrated with the base frame 21 by being screwed to the outdoor facing surfaces 21a on all sides of the base frame 21. However, the shutter frame 22 is fixed to the base frame 21 after the base frame 21 is screwed to the outer wall surface 130, as described later.

As shown in FIGS. 1, 2, and 4, the shutter box 3 is an oblong box-shaped member that includes a box body 31 and a cover member 32 that covers the outdoor side of the box body 31. As shown in FIG. 2, a shutter curtain 33 wound into a roll is housed inside the shutter box 3. Both sides of the shutter curtain 33 pulled out from the shutter box 3 are engaged with guide rails 4, 4 attached to the vertical frames 223, 223 of the shutter frame 22, respectively. The shutter curtain 33 smoothly opens and closes in the vertical direction by being guided by the guide rails 4, 4. In FIG. 4, the shutter curtain 33 inside the shutter box 3 is omitted.

As shown in FIG. 4, step eliminating members 5, 5 are attached to the indoor side of both lower ends of the base frame 21, respectively. The level difference eliminating member 5 eliminates the level difference formed between the surface of the upper exterior material 131 and the surface of the raised part 152 of the lower waterproof layer 150 with the drainer 132 as a boundary, and It has a function of preventing a gap from occurring between the stand-up portion 152 and the stand-up portion 152. The details of this step eliminating member 5 will be described further later.

Next, a structure for attaching the shutter device 1 to the outer wall surface 130 will be described. The vertical and horizontal sizes of the mounting frame 2 of the shutter device 1 are larger than the vertical and horizontal sizes of the window frame 121. Specifically, the vertical and horizontal sizes of the mounting frame 2 are large enough to accommodate the entire window frame 121 inside. Therefore, as shown in FIG. 2, the upper frame 211 and intermediate frame 214 of the base frame 21 are arranged above the upper frame 121a of the window frame 121. The lower frame 212 of the base frame 21 is arranged below the lower frame 121b of the window frame 121, and is arranged so as to cover the raised portion 152 of the waterproof layer 150 from the outdoor side. The left and right vertical frames 213, 213 of the base frame 21 are arranged outside the left and right vertical frames 121c, 121c of the window frame 121, respectively.

As shown in FIGS. 2 and 4, the upper frame 211 and intermediate frame 214 of the base frame 21 are each fixed to the outer wall surface 130 by a plurality of screws S1 and S2 passing through the exterior material 131. As shown in FIG. 4, the left and right vertical frames 213, 213 of the base frame 21, like the upper frame 211 and the intermediate frame 214, are each fixed to the outer wall surface 130 by a plurality of screws S3 passing through the exterior material 131. Ru. The portions where the vertical frames 213, 213 are fixed by the plurality of screws S3 are located above the drainer 132. However, the lower frame 212 of the base frame 21 is not fixed to the outer wall surface 130.

After the base frame 21 is screwed to the outer wall surface 130 in this manner, the shutter frame 22 is screwed to the base frame 21 from the outdoor side. As a result, the mounting frame 2 of the shutter device 1 is screwed onto the outer wall surface 130 only on three sides: the upper part by the upper frame 211 and the intermediate frame 214 of the base frame 21, and the left and right sides by the pair of vertical frames 213, 213. Fixed. The hatched areas in FIGS. 1 and 4 each indicate a fixing area C where the base frame 21 is screwed to the outer wall surface 130. Of the base frame 21 of the mounting frame 2 , the lower frame 212 arranged to cover the raised portion 152 of the waterproof layer 150 is not fixed to the outer wall surface 130 with screws. Therefore, the waterproof layer 150 will not be damaged and its water-stopping performance will not be impaired.

If the lower frame 212 of the base frame 21 is not fixed to the outer wall surface 130, there is a concern that the durability of the mounting frame 2 will be reduced. Therefore, the lower frame 212 of the base frame 21 has a reinforcing structure against the load applied to the lower frame 212. Specifically, the lower frame 212 has a larger cross-sectional area than the upper frame 211, the vertical frames 213, 213, and the intermediate frame 214, as shown in FIG. The cross-sectional area is the area of the outer shape of each frame when cut along a plane perpendicular to the extending direction. The large cross-sectional area of the lower frame 212 means that the lower frame 212 is thicker than the upper frame 211, the vertical frames 213, 213, and the intermediate frame 214. Normally, the amount of protrusion of the lower frame 212 toward the outdoors is set to be the same as that of the upper frame 211, the vertical frames 213, 213, and the intermediate frame 214. It is formed larger than the intermediate frame 214 in the vertical direction. This improves the strength of the lower frame 212 even if the lower frame 212 is not fixed to the outer wall surface 130 with screws. Therefore, the durability of the mounting frame 2 is ensured.

The reinforcing structure of the lower frame 212 of the base frame 21 is not limited to a structure in which the lower frame 212 has a large cross-sectional area. For example, as shown in FIG. 5, the reinforcing structure has a structure in which the thickness of the molding materials constituting the lower frame 212 is greater than the thickness of the molding materials constituting the upper frame 211, the vertical frames 213, 213, and the intermediate frame 214, respectively. It may be. The strength of the lower frame 212 is improved by increasing the thickness of the mold material.

As shown in FIG. 6, the reinforcing structure may be a structure in which a reinforcing core material 215 made of metal such as steel is attached inside the lower frame 212. By further attaching the reinforcing core material 215 inside the lower frame 212, the strength of the lower frame 212 is improved.

Furthermore, as shown in FIG. 7, the reinforcing structure may be a structure in which one or more bundle members 216 that are in contact with the outer floor surface 140 are attached to the lower surface 212a of the lower frame 212. Since the lower frame 212 is supported by the bundle member 216, the strength of the lower frame 212 is improved. The bundle member 216 is only placed on the floor portion 151 of the waterproof layer 150 and is not fixed with screws. Therefore, the water-stop performance of the waterproof layer 150 is not impaired.

These reinforcing structures are not limited to being used alone. Two or more types of reinforcement structures among these reinforcement structures may be combined. For example, FIGS. 5, 6, and 7 show a structure in which the cross-sectional area of the lower frame 212 is increased, a structure in which the thickness of the shape material of the lower frame 212 is increased, and a reinforcing core material 215 is attached inside the lower frame 212. The lower frame 212 is shown in which the structure and the structure in which the bundle member 216 is attached to the lower surface 212a of the lower frame 212 are combined. In this way, by combining multiple types of reinforcing structures, the durability of the mounting frame 2 can be further improved.

Although not shown, the same structure as the reinforcement structure of the lower frame 212 of the base frame 21 described above can also be applied to the lower frame 222 of the shutter frame 22. That is, the lower frame 222 of the shutter frame 22 may have a larger cross-sectional area than the upper frame 221 of the shutter frame 22 and the left and right vertical frames 223, 223. The thickness of the molding material forming the lower frame 222 of the shutter frame 22 may be larger than the thickness of the molding material forming the upper frame 221 and the left and right vertical frames 223, 223, respectively. Furthermore, a reinforcing core material made of metal such as steel may be attached inside the lower frame 222 of the shutter frame 22. The reinforcing structure applied to the lower frame 222 of the shutter frame 22 may be a combination of two or more of these.

Next, the step eliminating member 5 will be further explained with reference to FIGS. 8 to 10. The step eliminating member 5 is formed of a molded material extruded from a metal material such as aluminum. Specifically, as shown in FIGS. 8 and 9, the level difference eliminating member 5 includes a fixing plate 511 extending along the extending direction of the vertical frame 213 of the base frame 21, and a fixing plate 511 extending from both left and right sides of the fixing plate 511 toward the indoor side. The step eliminating member main body 51 includes a pair of side plates 512, 512 that protrude toward each other, and end plates 52, 52 are respectively disposed at both ends of the step eliminating member main body 51 in the length direction. The fixed plate 511 is provided with a plurality of screw holes 511a. The end plates 52, 52 are fixed to tapping holes 513, 513 provided on the inner surface of each side plate 512, 512 by mounting screws 53, respectively. As a result, the step eliminating member 5 is formed into a rectangular box shape with only the indoor side open.

The length of the step eliminating member 5 in the vertical direction is approximately equal to the length of the portion of the base frame 21 extending below the drain 132 of the outer wall surface 130. The width of the step eliminating member 5 is equal to or less than the width of the vertical frame 213 of the base frame 21. The height of the step eliminating member 5 along the indoor/outdoor direction is approximately equal to the distance between the base frame 21 and the raised portion 152 of the waterproof layer 150.

As shown in FIG. 9, the step eliminating members 5, 5 have a plurality of fixing screws that pass through the screw holes 511a of the fixing plate 511 on the indoor side finding surface 213a at the lower end of each of the vertical frames 213, 213 of the base frame 21. Fixed by S10. As a result, as shown in FIG. 10, the gap between the lower end of the base frame 21 of the mounting frame 2 and the raised portion 152 of the waterproof layer 150 below the drainer 132 is filled by the step eliminating members 5, 5. It will be done. Therefore, the attachment state of the lower end portion of the attachment frame 2 to the outer wall surface 130 is stabilized. Moreover, the step eliminating members 5, 5 are screwed to the respective vertical frames 213, 213 of the base frame 21, and are not fixed to the rising portion 152 of the waterproof layer 150, so that the waterproof layer 150 is not damaged. . Further, by providing the step eliminating members 5, 5, the gap between the lower end of the base frame 21 and the rising portion 152 is closed. Therefore, it is possible to prevent the shutter device 1 from being illegally unlocked by inserting a hand or the like through this gap.

As shown in FIGS. 8 and 9, a plurality of cut grooves 512a, 52a are provided in parallel in the pair of side plates 512 and end plate 52 of the step eliminating member 5, respectively. The cutout groove 512a of the side plate 512 extends the entire length of the step eliminating member 5 in the longitudinal direction. The cutout groove 52a of the end plate 52 extends the entire length of the end plate 52 in the width direction. The plurality of cut grooves 512a of the side plate 512 and the plurality of cut grooves 52a of the end plate 52 are arranged at the same position along the indoor/outdoor direction of the step eliminating member 5. Each of the cut grooves 512a, 52a has a depth from the outer surface of the side plate 512 and the end plate 52 to such an extent that it does not penetrate through the side plate 512 and the end plate 52. In the step eliminating member 5 of this embodiment, three cut grooves 512a, 52a are provided in each of the side plate 512 and the end plate 52, but the number of cut grooves is not particularly limited.

The length of the side plate 512 and the end plate 52 of the level difference eliminating member 5 in the indoor and outdoor directions is determined by cutting a part of the side plate 512 and the end plate 52 along one of the plurality of cut grooves 512a, 52a using, for example, pliers or the like. It can be adjusted by breaking it off using a tool. For example, FIG. 11 shows how the side plate 512 is broken off along the middle cutout groove 512a among the three cutout grooves 512a provided on each side plate 512, 512. As a result, the surplus portions 512b, 512b of the side plates 512 are removed from the side plates 512, 512, so that the dimensions of the side plates 512, 512 in the indoor and outdoor directions are adjusted to be shorter. Although not shown, the end plate 52 is also adjusted in the same way by breaking it off along one of the cut grooves 52a.

Since the side plate 512 and the end plate 52 each have a plurality of cut grooves 512a, 52a, the depth dimension of the step eliminating member 5 along the indoor/outdoor direction can be variously adjusted depending on the positions of the cut grooves 512a, 52a to be broken off. be. Therefore, the operator can appropriately select the positions of the cutout grooves 512a, 52a to be broken off according to the distance between the lower end of the mounting frame 2 and the rising part 152 of the waterproof layer 150, thereby making it possible to avoid steps at the work site. The depth dimension of the eliminating member 5 can be easily adjusted.

In the above embodiment, the shutter device 1 was exemplified as an opening shielding member for renovation that shields the outdoor side of a window. However, the opening shielding member for renovation is not limited to the shutter device. The opening shielding member for renovation is not limited as long as it has the function of shielding by being retrofitted to the outdoor side of the window 120 attached to the opening 110. For example, as shown in FIG. 12, the opening shielding member for renovation may be a shutter 6.

The shutter 6 shown in FIG. 12 has a mounting frame 7 having a width approximately 1.5 times that of the window frame 121. A door pocket 8 for storing a door body (not shown) is attached to the mounting frame 7. Similar to the mounting frame 2 of the shutter device 1, the mounting frame 7 of the shutter 6 is composed of a base frame 71 and a shutter frame 72 in which the door body is slidably housed laterally.

The base frame 71 is constructed by framing an upper frame 711, a lower frame 712, and a pair of left and right vertical frames 713, 713 into a rectangular shape. The mounting frame 7 of this storm door 6 is also fixed to the outer wall surface 130 by screws S21 and S22 passing through the exterior material 131 only on three sides, the upper frame 711 of the base frame 71 and the left and right vertical frames 73, 73. Since the lower frame 712 of the base frame 71 is not screwed to the upright portion 152 of the waterproof layer 150, the same effect as described above is achieved in that the water-stopping performance is not impaired. Furthermore, the lower frame 712 of the base frame 71 also has the same reinforcing structure as the lower frame 212 of the base frame 21 of the shutter device 1, thereby ensuring the durability of the mounting frame 7. The level difference eliminating member 5 is attached to the lower end of the base frame 71 in the same manner as described above. Therefore, the effect of stabilizing the attachment state of the lower end portion of the attachment frame 7 to the outer wall surface 130 can also be obtained.

As explained above, the mounting structure of the present embodiment is used as an opening shielding member having the mounting frames 2 and 7 attached to the outer wall surface 130 on the outside of the window frame 121 attached to the opening 110 of the building frame 100. The shutter device 1 and the shutter 6 are provided, and a waterproof layer 150 is provided below the opening 110. The lower frames 212, 712 are arranged so as to overlap the surface of the raised portion 152 of the waterproof layer 150, and have a reinforcing structure against the load applied to the lower frames 212, 712. , the upper frame 211, 711 and the pair of vertical frames 213, 713 are screwed to the outer wall surface 130 only on three sides. As a result, the mounting structure of the shutter device 1 and the shutter 6 for remodeling can be created that can sufficiently withstand the load applied to the lower frames 212, 712 of the mounting frames 2, 7 without reducing the water-stopping performance of the waterproof layer 150. provided.

In the mounting frame 2 of the shutter device 1 and the mounting frame 7 of the shutter 6 in the above embodiments, the base frames 21 and 71 are not essential components. The mounting frame 2 of the shutter device 1 may be comprised only of the shutter frame 22. The mounting frame 7 of the storm door 6 may also be comprised only of the shutter frame 72. Furthermore, the type of window installed in the opening 110 is not limited to a sliding window, but may be another type of window.
