Description

[Technical field]

[0001] The present disclosure relates to an attachment structure for a cover member for a retrofit opening. [Background technology]

[0002] Conventionally, there is known a mounting structure for a remodeling shutter in which the mounting frame of the shutter is screwed to the wall surface outside the window frame for retrofitting (see, for example, Patent Document 1). Because the mounting frame of this shutter is screwed to the wall surface on all four sides, the shutter can adequately withstand the load applied to it even if it is retrofitted. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2002-213169 A Summary of the Invention [Problem to be solved by the invention]

[0004] A waterproof layer made of FRP or similar is often installed on the wall below the window facing the balcony to stop water from entering. The waterproof layer is installed so as to cover the wall below the window and the exterior floor of the balcony.

[0005] If the mounting frame is screwed to the wall outside the window frame on all four sides in order to retrofit shutters to such windows, the screws used to fasten the sill may create holes in the waterproof layer, compromising the waterproofing performance. However, if the sill of the mounting frame is not screwed to the wall, the durability of the mounting frame against loads such as the weight and wind pressure on the sill is reduced.

[0006] Therefore, the inventor has discovered the problem of providing a mounting structure for a renovation opening cover member that does not reduce water-stopping performance and can adequately withstand the load applied to the bottom frame of the mounting frame. [Means for solving the problem]

[0007] One aspect of the present disclosure is an installation structure for an opening covering member for renovation, comprising an opening covering member having a mounting frame that is attached to an exterior wall surface outside a window frame fitted to an opening in a building structure, a waterproof layer is provided below the opening, the mounting frame has an upper frame, a lower frame and a pair of vertical frames, the lower frame is arranged to overlap the surface of the waterproof layer and has a reinforcing structure against loads applied to the lower frame, and the mounting frame is screwed to the exterior wall surface only on three sides, the upper frame and the pair of vertical frames.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, an embodiment of the present disclosure will be described in detail with reference to the drawings. Fig. 1 to Fig. 4 show a shutter device 1 attached to the outdoor side of a window 120 installed in an opening 110 of a building skeleton 100. X1 shown in the drawings indicates the outdoor side, and X2 indicates the indoor side. In this specification, in the shutter device 1, the surface arranged on the X1 side is defined as the outdoor side sighting surface, and the surface arranged on the X2 side is defined as the indoor side sighting surface.

[0010] As shown in Figures 2 and 3, the window 120 of this embodiment is a sliding window in which two paper screens 122, 122 are fitted inside a rectangular window frame 121 attached to the opening 110 so as to be able to slide laterally. A screen door 123 is fitted on the outdoor side of the paper screens 122, 122 so as to be able to slide laterally. In Figure 4, the paper screens 122 and the screen door 123 are omitted. This window 120 is attached separately from the shutter device 1 to the opening 110 facing the balcony on the second floor of the building.

[0011] An exterior material 131 is provided on the surface of the exterior wall surface 130 around the opening 110. As shown in FIG. 1, a lower end 131a of the exterior material 131 does not reach an exterior 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 drip edge 132 extending laterally is provided on the lower end 131a of the exterior material 131. No exterior material 131 is provided between the drip edge 132 and the exterior floor surface 140. Therefore, the exterior wall surface 130 below the drip edge 132 is recessed toward the interior side relative to the surface of the exterior material 131 by the amount that the exterior material 131 is not provided.

[0012] 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 skeleton 100. The waterproof layer 150 has a floor surface portion 151 provided on the exterior floor surface 140, and a rising portion 152 that is continuous with the floor surface portion 151 and rises along the exterior wall surface 130. The rising portion 152 covers the lower part of the exterior wall surface 130 between the exterior floor surface 140 and the drip edge 132.

[0013] The shutter device 1 is attached to an exterior wall surface 130 on the outside of a window 120 installed in an opening 110. That is, the shutter device 1 of this embodiment is a remodeling opening shielding member that is retrofitted to an existing window, the 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 this embodiment is composed of a base frame 21 and a shutter frame 22.

[0015] The base frame 21 is formed by arranging an upper frame 211, a lower frame 212, and a pair of left and right vertical frames 213, 213 into a rectangular shape. An intermediate frame 214 spanning the left and right vertical frames 213, 213 is provided slightly below the upper frame 211 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 made of extruded molding material 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 rectangular shape. An intermediate frame 224 spanning the left and right vertical frames 223, 223 is provided slightly below the upper frame 221 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 made of extruded molding material using a metal material such as aluminum.

[0017] 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-side visible surface 21a on all four 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 exterior wall surface 130, as described below.

[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, a shutter curtain 33 wound in 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 is guided by the guide rails 4, 4 to smoothly open and close in the vertical direction. In Fig. 4, the shutter curtain 33 in the shutter box 3 is omitted.

[0019] As shown in Fig. 4, level-eliminating members 5, 5 are attached to the indoor side of both ends of the lower end of the base frame 21. The level-eliminating members 5 have the function of eliminating the level difference 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 drip edge 132 as the boundary, and preventing the occurrence of a gap between the lower end of the base frame 21 and the rising portion 152. Details of the level-eliminating members 5 will be described later.

[0020] Next, the mounting structure of 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 the middle 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 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 arranged outside the left and right vertical frames 121c, 121c of the window frame 121, respectively.

[0021] 2 and 4, the upper frame 211 and middle frame 214 of the base frame 21 are each fixed to the exterior 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 each fixed to the exterior wall surface 130 by a plurality of screws S3 that penetrate the exterior material 131, similar to the upper frame 211 and middle frame 214. The fixing positions of the vertical frames 213, 213 by the plurality of screws S3 are positions above the drip edge 132. However, the lower frame 212 of the base frame 21 is not fixed to the exterior wall surface 130.

[0022] After the base frame 21 is screwed to the exterior 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 to the exterior wall surface 130 only on three sides: the upper side by the upper frame 211 and the middle frame 214 of the base frame 21, and the left and right sides by the pair of vertical frames 213, 213. The parts indicated by diagonal lines in Figs. 1 and 4 indicate the fixing areas C where the base frame 21 is screwed to the exterior wall surface 130. Of 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 exterior wall surface 130. Therefore, the waterproof layer 150 is not damaged, and the waterproof 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 exterior wall surface 130. Therefore, the lower frame 212 of the base frame 21 has a reinforcing structure against the load applied to the lower frame 212. In detail, as shown in FIG. 2, the lower frame 212 has a larger cross-sectional area than the upper frame 211, the vertical frames 213, 213, and the middle frame 214. The cross-sectional area is the area of ​​the outer shape when cut by a plane perpendicular to the extension direction of each frame. 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 middle frame 214. Usually, the protrusion 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 middle frame 214, so that the lower frame 212 is formed larger in the vertical direction than the upper frame 211, the vertical frames 213, 213, and the middle frame 214. 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.

[0024] The reinforcing structure of the lower frame 212 of the base frame 21 is not limited to a structure in which the cross-sectional area of ​​the lower frame 212 is large. For example, as shown in Fig. 5, the reinforcing structure may be a structure in which the plate thickness of the mold material constituting the lower frame 212 is greater than the plate thicknesses of the mold materials constituting the upper frame 211, the vertical frames 213, 213, and the intermediate frame 214. The greater plate thickness of the mold material improves the strength of the lower frame 212.

[0025] 6, the reinforcing structure may be a structure in which a reinforcing core material 215 made of a 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.

[0026] 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. The lower frame 212 is supported by the bundle members 216, which improves the strength of the lower frame 212. The bundle members 216 are simply placed on the floor surface portion 151 of the waterproof layer 150, and are not fixed with screws. Therefore, the waterproof 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, Fig. 5, Fig. 6, and Fig. 7 show a lower frame 212 in which a structure for increasing the cross-sectional area of ​​the lower frame 212 is combined with a structure for increasing the plate thickness of the mold material of the lower frame 212, a structure in which a reinforcing core material 215 is attached inside the lower frame 212, and a structure in which a bundle member 216 is attached to the lower surface 212a of the lower frame 212. In this way, by combining multiple reinforcing structures, the durability of the mounting frame 2 can be further improved.

[0028] Although not shown, the same configuration as 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. That is, the lower frame 222 of the shutter frame 22 may have a larger cross-sectional area than the upper frame 221 and the left and right vertical frames 223, 223 of the shutter frame 22. The plate thickness of the mold material constituting the lower frame 222 of the shutter frame 22 may be larger than the plate thickness of the mold material constituting the upper frame 221 and the left and right vertical frames 223, 223 of the shutter frame 22. 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.

[0029] Next, the step elimination member 5 will be described with reference to Figs. 8 to 10. The step elimination member 5 is made of a molded material extruded using a metal material such as aluminum. In detail, as shown in Figs. 8 and 9, the step elimination member 5 has a step elimination member main body 51, which is made up of a fixed plate 511 extending along the extension direction of the vertical frame 213 of the base frame 21 and a pair of side plates 512, 512 protruding from both left and right sides of the fixed plate 511 toward the indoor side, and end plates 52, 52 arranged at both ends in the length direction of the step elimination member main body 51. The fixed plate 511 is provided with a plurality of screw holes 511a. The end plates 52, 52 are fixed by mounting screws 53 to tapping holes 513, 513 provided on the inner surface of each side plate 512, 512. As a result, the step elimination member 5 is formed into a rectangular box shape with only the indoor side open.

[0030] The vertical length of the level difference elimination member 5 is approximately equal to the length of the portion of the base frame 21 that extends below the underside 132 of the exterior wall surface 130. The horizontal width of the level difference elimination member 5 is equal to or smaller than the horizontal width of the vertical frame 213 of the base frame 21. The height of the level difference elimination member 5 in the indoor-outdoor direction is approximately 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 facing surface 213a of the lower end of each vertical frame 213, 213 of the base frame 21 by a plurality of fixing screws S10 penetrating 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 part 152 of the waterproof layer 150 below the drip edge 132 is filled by the step elimination members 5, 5. Therefore, the mounting state of the lower end of the mounting frame 2 to the exterior wall surface 130 is stable. Moreover, the step elimination members 5, 5 are screwed to each vertical frame 213, 213 of the base frame 21 and are not fixed to the rising part 152 of the waterproof layer 150, so that the waterproof layer 150 is not damaged. Furthermore, the step elimination members 5, 5 are provided to close the gap between the lower end of the base frame 21 and the rising part 152. This prevents unauthorized unlocking of the shutter device 1 by inserting a hand or the like through this gap.

[0032] As shown in Figs. 8 and 9, a pair of side plates 512 and end plates 52 of the step-eliminating member 5 are each provided with a plurality of cutout grooves 512a, 52a in parallel. The cutout groove 512a of the side plate 512 extends over the entire length of the step-eliminating member 5 in the length direction. The cutout groove 52a of the end plate 52 extends over the entire width of the end plate 52. The cutout grooves 512a of the side plate 512 and the cutout 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 cutout groove 512a, 52a has a depth from the outer surface of the side plate 512 and the end plate 52, respectively, such that it does not penetrate 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.

[0033] The length of the side plate 512 and the end plate 52 of the step-eliminating member 5 in the indoor / outdoor direction can be adjusted by breaking off a part of the side plate 512 and the end plate 52 along any one of the multiple cutout grooves 512a, 52a using a tool such as pliers. For example, FIG. 11 shows how the side plate 512 is broken off along the middle cutout groove 512a of the three cutout grooves 512a provided on each side plate 512, 512. As a result, the excess portions 512b, 512b of the side plate 512 are removed from the side plate 512, 512, and the dimension of the side plate 512, 512 in the indoor / outdoor direction is adjusted to be shorter. Although not shown, the end plate 52 can also be similarly adjusted by breaking it off along any one of the cutout grooves 52a.

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

[0035] In the above embodiment, a shutter device 1 has been exemplified as a member for covering an opening for renovation that covers the outdoor side of a window. However, the member for covering an opening for renovation is not limited to a shutter device. There are no limitations on the member for covering an opening for renovation as long as it has a function of covering by being attached to the outdoor side of a window 120 that is attached to an opening 110. For example, as shown in FIG. 12, the member for covering an opening for renovation may be a storm shutter 6.

[0036] The storm shutter 6 shown in Fig. 12 has a mounting frame 7 with a width approximately 1.5 times that of a window frame 121. A door pocket 8 for storing a door body (not shown) is attached to the mounting frame 7. The mounting frame 7 of the storm shutter 6, like the mounting frame 2 of the shutter device 1, is composed of a base frame 71 and a storm shutter frame 72 in which the door body is housed so as to be slidable laterally.

[0037] The base frame 71 is formed by framing an upper frame 711, a lower frame 712, and a pair of left and right vertical frames 713, 713 in a rectangular shape. The mounting frame 7 of the shutter 6 is also fixed to the exterior wall surface 130 only on three sides, the upper frame 711 of the base frame 71 and the left and right vertical frames 73, 73, by screws S21, S22 penetrating the exterior material 131. The lower frame 712 of the base frame 71 is not screwed to the rising portion 152 of the waterproof layer 150, so that the waterproof performance is not impaired as described above. Furthermore, the lower frame 712 of the base frame 71 also has a reinforcing structure similar to the lower frame 212 of the base frame 21 of the shutter device 1, so that the durability of the mounting frame 7 is ensured. The step elimination member 5 is attached to the lower end of the base frame 71 as described above. Therefore, the mounting state of the lower end of the mounting frame 7 relative to the exterior wall surface 130 is stabilized.

[0038] As described above, the mounting structure of this embodiment comprises a shutter device 1 and a storm shutter 6 as an opening shielding member having mounting frames 2, 7 attached to the exterior wall surface 130 outside the window frame 121 attached to the opening 110 of the building structure 100, a waterproof layer 150 is provided below the opening 110, the mounting frames 2, 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 arranged to overlap the surface of the rising portion 152 of the waterproof layer 150 and have a reinforcing structure against loads applied to the lower frames 212, 712, and the mounting frames 2, 7 are screwed to the exterior wall surface 130 only on three sides, the upper frame 211, 711 and the pair of vertical frames 213, 713. This provides a mounting structure for the shutter device 1 and the storm shutters 6 for renovation that does not reduce the waterproof performance of the waterproof layer 150 and can adequately withstand the load applied to the bottom frames 212, 712 of the mounting frames 2, 7.

[0039] In the above embodiment, the base frames 21, 71 are not essential components of the mounting frame 2 of the shutter device 1 and the mounting frame 7 of the storm shutter 6. The mounting frame 2 of the shutter device 1 may be composed of only the shutter frame 22. The mounting frame 7 of the storm shutter 6 may be composed of only the storm shutter frame 72. Furthermore, the type of window installed in the opening 110 is not limited to a sliding window, and may be another type of window. [Explanation of symbols]
