Summary of the Invention

Problems to be Solved by the Invention

[0004] On the wall surface below the window facing the balcony, a waterproof layer made of FRP or the like is often provided for water stoppage. The waterproof layer is provided so as to cover the outer floor surface of the balcony from the outer wall surface below the opening where the window is mounted. Further, an exterior material is provided on the outer wall surface where the window is mounted for improving the durability and design of the building. The exterior material is not provided below the opening where the window is mounted in order to avoid damage to the waterproof layer. Therefore, a step is formed between the lower end portion of the exterior material and the outer wall surface where the exterior material is not provided.

[0005] When a shutter is retrofitted outside such a window, there is a problem that a gap is generated between the lower end portion of the attachment frame of the shutter and the outer wall surface without the exterior material below the opening.

[0006] Therefore, the inventor has found a problem of providing an attachment structure of a retrofit opening shielding member that can eliminate the step between the portion where the exterior material is provided and the portion where the exterior material is not provided and can stably attach the attachment frame to the outer wall surface.

Means for Solving the Problem

[0007] One aspect of the present disclosure includes an opening shielding member having a mounting frame attached to an outer wall surface outside a window frame attached to an opening of a building body. The mounting frame has an upper frame, a lower frame, and a pair of vertical frames. The lower frame is disposed below the opening. An exterior material is provided on the outer wall surface, and the exterior material is not provided below the opening. A step is formed between a lower end portion of the exterior material and the outer wall surface where the exterior material is not provided. A step eliminating member for filling a gap due to the step is attached to an indoor side of a lower end portion of the mounting frame. This is an attachment structure of a retrofit opening shielding member.

Mode for Carrying Out the Invention

[0009] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. FIGS. 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 body 100. X1 shown in the figure indicates the outdoor side, and X2 indicates the indoor side. In this specification, in the shutter device 1, a surface disposed on the X1 side is defined as an outdoor side finding surface, and a surface disposed on the X2 side is defined as an indoor side finding surface.

[0010] As shown in FIGS. 2 and 3, the window 120 of the present embodiment is a sliding window in which two shoji 122, 122 are horizontally slidably accommodated inside a rectangular window frame 121 attached to the opening 110. A screen door 123 is horizontally slidably accommodated on the outdoor side of the shoji 122, 122. 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.

[0011] 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 portion 131a of the exterior material 131 does not reach the outer floor surface 140 which is the floor surface of the balcony, and is disposed slightly above the lower end of the window frame 121. A drain 132 extending in the horizontal direction is provided at the lower end portion 131a of the exterior material 131. The exterior material 131 is not provided between the drain 132 and the outer floor surface 140. That is, the exterior material 131 does not exist below the opening 110. Therefore, the outer wall surface 130 below the drain 132 is recessed inward with respect to the surface of the exterior material 131 because the exterior material 131 is not provided.

[0012] 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 body 100. The waterproof layer 150 has a floor surface portion 151 provided on the outer floor surface 140 and a rising portion 152 that is continuously raised along the outer wall surface 130 from the floor surface portion 151. The rising portion 152 covers the lower part of the outer wall surface 130 between the outer floor surface 140 and the drain 132.

[0013] The shutter device 1 is attached to the outer wall surface 130 outside the window 120 attached to the opening 110. That is, the shutter device 1 of the present embodiment is a retrofit opening shielding member that is retrofitted to the existing window 120. The shutter device 1 has a rectangular mounting frame 2, a shutter box 3 attached to the upper part of the mounting frame 2, and a pair of guide rails 4, 4.

[0014] As shown in FIG. 4, the mounting frame 2 of the present embodiment is composed of a base frame 21 and a shutter frame 22.

[0015] 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 in a rectangle. An intermediate frame 214 extending across the left and right vertical frames 213, 213 is provided parallel to the upper frame 211 and the lower frame 212 slightly below the upper frame 211. These upper frame 211, lower frame 212, vertical frames 213, 213, and intermediate frame 214 are all composed of extruded profiles using a metal material such as aluminum.

[0016] 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 in a rectangle. An intermediate frame 224 extending across the left and right vertical frames 223, 223 is provided parallel to the upper frame 221 and the lower frame 222 slightly below the upper frame 221. These upper frame 221, lower frame 222, vertical frames 223, 223, and intermediate frame 224 are all composed of extruded profiles using a metal material such as aluminum.

[0017] The vertical and horizontal sizes of the shutter frame 22 are substantially 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 surface 21a of the base frame 21 that extends around all four sides of the base frame 21. However, the fixing of the shutter frame 22 to the base frame 21 is performed after the base frame 21 is screwed to the outer wall surface 130, as will be described later.

[0018] As shown in FIGS. 1, 2, and 4, the shutter box 3 is a horizontally long box-shaped member composed of a box body 31 and a cover member 32 that covers the outdoor side of the box body 31. As shown in FIG. 2, inside the shutter box 3, a shutter curtain 33 wound in a roll shape is accommodated. Both side portions of the shutter curtain 33 pulled out from the shutter box 3 are engaged with guide rails 4, 4 respectively attached to the vertical frames 223, 223 of the shutter frame 22. The shutter curtain 33 smoothly opens and closes along 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.

[0019] As shown in FIG. 4, step elimination members 5, 5 are respectively attached to the indoor sides of both end portions at the lower end of the base frame 21. The step elimination member 5 has a function of eliminating the step formed between the surface of the upper exterior material 131 and the surface of the rising portion 152 of the lower waterproof layer 150 with the water drainage 132 as the boundary, so as to prevent a gap from occurring between the lower end portion of the base frame 21 and the rising portion 152. Details of this step elimination member 5 will be further described later.

[0020] Next, the mounting structure of the shutter device 1 on 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 sized such that the entire window frame 121 can be accommodated inside. Therefore, as shown in FIG. 2, the upper frame 211 and the intermediate frame 214 of the base frame 21 are disposed above the upper frame 121a of the window frame 121. The lower frame 212 of the base frame 21 is disposed below the lower frame 121b of the window frame 121 and is arranged to cover the rising 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 respectively disposed outside the left and right vertical frames 121c, 121c of the window frame 121.

[0021] As shown in FIGS. 2 and 4, the upper frame 211 and the intermediate frame 214 of the base frame 21 are respectively fixed to the outer wall surface 130 by a plurality of screws S1, S2 that penetrate the exterior material 131. As shown in FIG. 4, the left and right vertical frames 213, 213 of the base frame 21 are respectively fixed to the outer wall surface 130 by a plurality of screws S3 that penetrate the exterior material 131, similar to the upper frame 211 and the intermediate frame 214. The fixing portions of the vertical frames 213, 213 by the plurality of screws S3 are portions above the drainage 132. However, the lower frame 212 of the base frame 21 is not fixed to the outer wall surface 130.

[0022] After the base frame 21 is screwed to the outer wall surface 130 in this way, the shutter frame 22 is screwed to the base frame 21 from the outdoor side. Thereby, the mounting frame 2 of the shutter device 1 is screwed to the outer wall surface 130 only in three directions: above by the upper frame 211 and the intermediate frame 214 of the base frame 21 and on the left and right sides by the pair of vertical frames 213, 213. The portions indicated by hatching in FIGS. 1 and 4 respectively show the fixing regions C where the base frame 21 is screwed to the outer wall surface 130. Among the base frame 21 of the mounting frame 2, the lower frame 212 arranged to cover the rising portion 152 of the waterproof layer 150 is not screwed to the outer wall surface 130. Therefore, the waterproof layer 150 is not damaged and the water-stopping performance is not impaired.

[0023] There is a concern that the durability of the mounting frame 2 may decrease because the lower frame 212 of the base frame 21 is not fixed to the outer wall surface 130. Therefore, the lower frame 212 of the base frame 21 has a reinforcement structure against the load applied to the lower frame 212. Specifically, as shown in FIG. 2, the lower frame 212 has a larger cross-sectional area compared to the upper frame 211, the vertical frames 213, 213, and the intermediate frame 214. The cross-sectional area is the area of the outer shape when cut by a plane orthogonal to the extending direction of each frame. The fact that the cross-sectional area of the lower frame 212 is large means that the lower frame 212 is thicker than the upper frame 211, the vertical frames 213, 213, and the intermediate frame 214. Usually, since the protruding amount of the lower frame 212 to the outdoor side is set to be equal to that of the upper frame 211, the vertical frames 213, 213, and the intermediate frame 214, the lower frame 212 is formed larger in the vertical direction than the upper frame 211, the vertical frames 213, 213, and the intermediate frame 214. As a result, even if the lower frame 212 is not screwed to the outer wall surface 130, the strength of the lower frame 212 is improved. Therefore, the durability of the mounting frame 2 is ensured.

[0024] The reinforcement structure of the lower frame 212 of the base frame 21 is not limited to the structure in which the lower frame 212 has a large cross-sectional area. For example, as shown in FIG. 5, the reinforcement structure may be a structure in which the plate thickness of the profile constituting the lower frame 212 is larger than the plate thickness of the profiles respectively constituting the upper frame 211, the vertical frames 213, 213, and the intermediate frame 214. Since the plate thickness of the profile is large, the strength of the lower frame 212 is improved.

[0025] As shown in FIG. 6, the reinforcement structure may be a structure in which a metal reinforcement core member 215 such as steel is attached inside the lower frame 212. Since the reinforcement core member 215 is further attached inside the lower frame 212, the strength of the lower frame 212 is improved.

[0026] Furthermore, as shown in FIG. 7, the reinforcement structure may be a structure in which one or more bundling members 216 that are grounded to 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 bundling members 216, the strength of the lower frame 212 is improved. The bundling members 216 are only placed on the floor surface portion 151 of the waterproof layer 150 and are not screwed. Therefore, the water-stopping performance of the waterproof layer 150 is not impaired.

[0027] These reinforcing structures are not limited to being used alone. Two or more of these reinforcing structures may be combined. For example, FIGS. 5, 6, and 7 show a structure for increasing the cross-sectional area of the lower frame 212, a structure for increasing the plate thickness of the profile of the lower frame 212, a structure in which a reinforcing core member 215 is attached inside the lower frame 212, and a structure in which a bundling member 216 is attached to the lower surface 212a of the lower frame 212, respectively, combined in the lower frame 212. In this way, by combining multiple types of reinforcing structures, the durability of the mounting frame 2 can be further improved.

[0028] A configuration similar to the reinforcing 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, although not shown. That is, the lower frame 222 of the shutter frame 22 may have a larger cross-sectional area compared to the upper frame 221 and the left and right vertical frames 223, 223 of the shutter frame 22. The plate thickness of the profile constituting the lower frame 222 of the shutter frame 22 may have a structure that is larger than the plate thickness of the profile constituting each of the upper frame 221 and the left and right vertical frames 223, 223 of the shutter frame 22. Further, a metal reinforcing core member 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.

[0029] Next, the step elimination member 5 will be further described with reference to FIGS. 8 to 10. The step elimination member 5 is composed of a profile extruded using a metal material such as aluminum. Specifically, as shown in FIGS. 8 and 9, the step elimination member 5 includes a fixing plate 511 extending along the extending direction of the vertical frame 213 of the base frame 21, and a pair of side plates 512, 512 protruding inward from both left and right sides of the fixing plate 511 toward the indoor side. The step elimination member 5 includes a step elimination member main body 51 constituted by the above, and end plates 52, 52 respectively disposed at both ends in the length direction of the step elimination member main body 51. A plurality of screw holes 511a are provided in the fixing plate 511. The end plates 52, 52 are respectively fixed to tapping holes 513, 513 provided on the inner surfaces of the side plates 512, 512 by mounting screws 53. Thereby, the step elimination member 5 is formed in a rectangular box shape with only the indoor side open. However, the pair of end plates 52, 52 do not necessarily have to be provided.

[0030] The vertical length of the step elimination member 5 is substantially equal to the length of the portion where the base frame 21 extends below the water drainage portion 132 of the outer wall surface 130. The lateral width of the step elimination member 5 is equal to or less than the lateral width of the vertical frame 213 of the base frame 21. The height of the step elimination member 5 along the indoor-outdoor direction is substantially equal to the distance between the base frame 21 and the rising portion 152 of the waterproof layer 150.

[0031] As shown in Fig. 9, the step elimination members 5, 5 are fixed to the indoor-side finding surfaces 213a at the lower ends of the respective vertical frames 213, 213 of the base frame 21 by a plurality of fixing screws S10 passing through the screw holes 511a of the fixing plate 511. 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 rising portion 152 of the waterproof layer 150 below the water cut-off 132 is filled by the step elimination members 5, 5. Therefore, the mounting state of the lower end of the mounting frame 2 with respect to the outer wall surface 130 is stabilized. Moreover, since the step elimination members 5, 5 are screw-fixed 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, the waterproof layer 150 is not damaged. Further, by providing the step elimination members 5, 5, the gap between the lower end of the base frame 21 and the rising portion 152 is blocked. Therefore, it is also possible to prevent a hand or the like from being inserted through this gap and the shutter device 1 from being illegally unlocked.

[0032] As shown in Figs. 8 and 9, a plurality of cutout grooves 512a, 52a are provided in parallel on the pair of side plates 512 and the end plates 52 of the step elimination member 5, respectively. The cutout grooves 512a of the side plates 512 extend over the entire length of the step elimination member 5 in the longitudinal direction. The cutout grooves 52a of the end plates 52 extend over the entire length of the end plates 52 in the width direction. The plurality of cutout grooves 512a of the side plates 512 and the plurality of cutout grooves 52a of the end plates 52 are arranged at the same position along the indoor-outdoor direction of the step elimination member 5. Each of the cutout grooves 512a, 52a has a depth that does not penetrate the side plates 512 and the end plates 52 from their respective outer surfaces. In the step elimination member 5 of the present embodiment, three cutout grooves 512a, 52a are provided in each of the side plates 512 and the end plates 52, but the number of cutout grooves is not particularly limited.

[0033] The lengths of the side plates 512 and the end plates 52 of the step elimination member 5 in the indoor / outdoor direction can be adjusted by folding a part of the side plates 512 and the end plates 52 along any one of the plurality of cutout grooves 512a, 52a, for example, using a tool such as pliers. For example, FIG. 11 shows a state in which the side plate 512 is folded along the middle cutout groove 512a out of the three cutout grooves 512a provided on each of the side plates 512, 512. As a result, the surplus portions 512b, 512b of the side plates 512, 512 are removed from the side plates 512, 512, so that the dimensions of the side plates 512, 512 in the indoor / outdoor direction are adjusted to be shorter. Although not shown, the end plate 52 is similarly adjusted by folding it along any one of the cutout grooves 52a.

[0034] Since the side plates 512 and the end plates 52 each have a plurality of cutout grooves 512a, 52a, the depth dimension of the step elimination member 5 along the indoor / outdoor direction can be adjusted in various ways depending on the positions of the cutout grooves 512a, 52a to be folded. Therefore, the operator can easily adjust the depth dimension of the step elimination member 5 at the work site by appropriately selecting the positions of the cutout grooves 512a, 52a to be folded according to the distance between the lower end portion of the mounting frame 2 and the rising portion 152 of the waterproof layer 150.

[0035] In the above embodiment, the shutter device 1 is exemplified as the retrofit opening shielding member for shielding the outdoor side of the window. However, the retrofit opening shielding member is not limited to the shutter device. The retrofit opening shielding member has no limitation as long as it has a shielding function by being retrofitted to the outdoor side of the window 120 mounted in the opening 110. For example, as shown in FIG. 12, the retrofit opening shielding member may be a sliding window 6.

[0036] The sliding window 6 shown in FIG. 12 has a mounting frame 7 having a width approximately 1.5 times that of the window frame 121. A pocket 8 for storing a window 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 sliding window 6 is composed of a base frame 71 and a sliding window frame 72 in which the window body is slidably housed in the lateral direction.

[0037] The base frame 71 is configured by framing an upper frame 711, a lower frame 712, and a pair of left and right vertical frames 713, 713 in a rectangle. The mounting frame 7 of this shutter 6 is also fixed to the outer wall surface 130 by screws S21, S22 that penetrate the exterior material 131 only at the upper frame 711 and the left and right vertical frames 73, 73 of the base frame 71. Since the lower frame 712 of the base frame 71 is not screwed to the rising portion 152 of the waterproof layer 150, similarly to the above, it has the effect of not impairing the water stop performance. Furthermore, the lower frame 712 of this base frame 71 also has the same reinforcement structure as the lower frame 212 of the base frame 21 of the shutter device 1, thereby having the effect of ensuring the durability of the mounting frame 7. A step elimination member 5 is attached to the lower end portion of the base frame 71 in the same manner as above. Therefore, the effect of stabilizing the mounting state of the lower end portion of the mounting frame 7 with respect to the outer wall surface 130 is also obtained.

[0038] As described above, the mounting structure of the present embodiment includes shutter devices 1 and storm doors 6 having mounting frames 2 and 7 attached to the outer wall surface 130 outside the window frame 121 attached to the opening 110 of the building body 100. The mounting frames 2 and 7 have an upper frame 211, 711, a lower frame 212, 712, and a pair of vertical frames 213, 713. The lower frames 212, 712 are disposed below the opening 110, and an exterior material 131 is provided on the outer wall surface 130. The exterior material 131 is not provided below the opening 110, and a step is formed between the lower end portion 131a of the exterior material 131 and the outer wall surface 130 where the exterior material 131 is not provided. A step elimination member 5 that fills the gap due to the step is attached to the indoor side of the lower end portion of the mounting frames 2 and 7. Thereby, a mounting structure of the shutter device 1 and the storm door 6 is provided that can eliminate the step between the portion where the exterior material 131 is provided and the portion where the exterior material 131 is not provided and stably attach the mounting frames 2 and 7 to the outer wall surface 130.

[0039] In the mounting frames 2 of the shutter device 1 and the mounting frame 7 of the window 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 constituted only by the shutter frame 22. The mounting frame 7 of the window shutter 6 may also be constituted only by the window shutter frame 72. Further, the type of window mounted in the opening 110 is not limited to a sliding window, and other types of windows may be used.
