Description

  The present invention relates to a fixing structure for fixing a shutter to a vertical frame of a window when the shutter is retrofitted to an existing window of a building such as a house.

  In many cases, it is necessary to attach a shutter to an existing window of a building such as a house. In such shutters, the doors are essential, and there is a problem that the doors cannot be installed without the space necessary to provide the doors in the left-right direction, and even if the shutters are attached, they can be opened and closed every morning and in the rain. This may cause problems such as inconvenience to the neighborhood due to noise generated during opening and closing, and labor and time required for opening and closing.

  For this reason, there is an increasing demand for retrofitting a shutter to an existing window in a building instead of a shutter, or retrofitting a shutter to a window where a shutter cannot be attached from the viewpoint of crime prevention. In particular, when an electric shutter is used as a shutter, there is an advantage that noise can be reduced and labor can be reduced.

  The shutter is provided with a shutter box having a shaft around which a slat is wound at the upper end, a vertical frame provided with a slat rail at each of the left and right ends of the shutter box, and both vertical frames at the lower end of the vertical frame. A connecting lower frame is arranged. In particular, because the weight of the shutter box is large, when installing the shutter at the time of new construction, it is common to configure the shutter box so that the weight of the shutter can be supported by the casing by penetrating the outer wall and fixing the shutter box to the casing. Is.

  Also, for example, when the outer wall has a sufficiently higher strength than the siding board, such as lightweight cellular concrete panel or precast concrete panel, the back of the shutter box (surface facing the outer wall) is directly fixed to the outer wall with screws. Or it is common practice to form a hole in the outer wall and fix it to the housing.

  However, retrofitting the shutter as described above requires removing a part of the outer wall at the top of the window or repairing the outer wall after installing the shutter, which must be a major construction. There's a problem.

  For this reason, when retrofitting a shutter to an existing window of a building, a shutter with a retrofit specification is configured such that the back side (the back side of the shutter box and the back side of the shutter vertical frame having the slat guide) is arranged in the same plane. In general, this retrofit type shutter is attached using the outer wall around the window.

  For example, as described in Patent Document 1, an attachment frame body of a retrofit shutter is fixed to an outer wall surface on the outer circumference of the window frame, and a retrofit shutter is attached to the attachment frame body via a wall attachment. Done. With this technique, even when the outer wall is thin like a siding board or has elasticity, the outer wall surface is not dented, and a reliable mounting structure can be expected.

JP 2002-213169 A

  In the technique described in Patent Document 1 and other conventional techniques, a shutter is attached to an outer wall around a window of an existing building using a screw or the like. Thus, a screw is fastened to or penetrates the outer wall, and there is a risk of water leakage due to a gap formed between the screw and the outer wall. For this reason, it is indispensable to perform sealing around the screw. However, there is a problem in that the work of performing the sealing becomes complicated and the sealing needs to be re-executed after a predetermined period.

  In the technique described in Patent Document 1, since the shutter mounting frame body is fixed using the outer wall on the outer circumference of the window to be attached, the left-right dimension of the shutter must be larger than the size of the window. Absent. For this reason, the shutter attached to the window of a new building and the shutter retrofitted to the window of an existing building become shutters of different specifications with different widths, which causes a problem that management becomes complicated.

  An object of the present invention is to provide a shutter fixing structure that is easy to construct without damaging the outer wall and without increasing the width of the shutter to be attached.

  In order to solve the above problems, the shutter fixing structure according to the present invention is a fixing structure for fixing a shutter to an existing window, and a long structure material is fixed to the outer surface of a vertical frame of the window, and this long structure By fixing the side bracket of the shutter to the material, the shutter is fixed to the vertical frame of the window.

  In the shutter fixing structure, it is preferable that the long structural member is substantially equal to the length of the vertical frame of the window.

  In the shutter fixing structure, it is preferable to fix a long support member to the side bracket of the shutter and to fix the long support member to the long structural member. It is preferable to have a length extending downward from the lower end of the side bracket of the shutter.

  In the shutter fixing structure according to the present invention, a long structural material (hereinafter simply referred to as “structural material”) is fixed to the outer surface of the vertical frame of an existing window, and the shutter side bracket is fixed to the structural material, Since the shutter is fixed to the vertical frame of the window, when the shutter is retrofitted to an existing window, parts other than the vertical frame of the window (frame and outer wall) are not damaged. That is, since the casing at the upper part of the existing window and the surrounding outer wall are not damaged, the quality of the casing can be ensured and water leakage due to the retrofit of the shutter can be prevented.

  Moreover, even when the surface of the window frame is retracted to the indoor side with respect to the outer wall surface, it is possible to cope with the structural material having a length substantially equal to the vertical frame of the window. In addition, it is possible to set the distance between the shutter surface and the window surface to a desired size by appropriately setting the protruding dimension of the structural material window from the vertical frame, so it can be used with windows other than sliding windows. can do.

  When a long support member is fixed to the side bracket of the shutter, or when the side bracket and the long support member are integrated and this support member is fixed to a structural material, the shutter box and the upper part of the window The distance can be set as appropriate, and it is possible to deal with shutters having different structures.

  In particular, when the support member is configured to have a length that extends downward from the side bracket of the shutter, the shutter can be easily attached to the structural material. Furthermore, it is possible to more easily perform installation by forming bolt holes in advance at predetermined positions of the support member, the structural material, or the side bracket.

  Hereinafter, the most preferable embodiment of the shutter fixing structure of the present invention will be described. The shutter fixing structure of the present invention is advantageous to be applied when retrofitting a shutter to an existing window installed in a building, and in particular, since only the vertical frame of the window is used, it is applied to the frame or outer wall of the existing building. Construction is possible without any damage. For this reason, there is no possibility of water leakage due to the retrofitting of the shutter.

  In the present invention, an existing window in a building may have a vertical frame having sufficient strength and sufficient width, and the structure and material are not limited at all. That is, it may be a window made of wooden joinery, a metal sash whose window frame is made of aluminum or steel, or a synthetic resin sash whose window frame is made of synthetic resin.

  In the present invention, the shutter to be attached to the window is not particularly limited, but an existing shutter that is attached to the window when a new building is constructed is targeted. Such a shutter is attached by fixing a frame arranged in a shutter box to a building frame at the time of new construction. Therefore, the weight of the shutter is transmitted to the building frame through the frame. Further, when the shutter box is fixed to the housing, the rear face of the shutter vertical frame is positioned on the same surface as the outer surface of the window frame.

  In the present invention, the shutter is not limited to a driving method at the time of opening and closing, and an electric shutter that drives the winding shaft by an electric motor or a manual shutter that is manually operated is selectively used. Is possible.

  The structural material of the present invention has a function of transmitting the weight of the shutter to the vertical frame of the window, and is fixed to the vertical frame of the window and directly or indirectly fixes the side bracket of the shutter. The structural material is not limited as long as it can exhibit the above functions. However, as a structural material, it is necessary to have a fixed piece fixed to the vertical frame of the window and an attachment piece for fixing the shutter, and the shape of each piece is outside the vertical frame of the target window. It is preferable to set appropriately according to the shape of the surface (surface on the outdoor side) and the shape of the member capable of supporting the weight of the shutter.

  In order to convey the weight of the shutter to the vertical frame of the window in a stable state, the structural material preferably has a length substantially equal to the vertical frame of the window. In this way, the structural material and the vertical frame of the window have substantially the same length, so that the structural material can be arranged over the substantially entire length of the vertical frame of the window, and the weight of the shutter is distributed substantially evenly. It becomes possible to support.

  The fixed piece of the structural material is appropriately set corresponding to the structure of the outer surface of the vertical frame of the window to be fixed. For example, when an existing window of a building is an aluminum sash, and a groove that can be slid by inserting a bolt head or a nut in advance on the outer surface of the aluminum sash is formed, a fixed piece of structural material Preferably has a width dimension smaller than the width of the outer surface of the aluminum sash and is formed with a bolt hole for inserting the bolt. In addition, when the window is a flat surface such as a wooden joinery or a steel sash, the fixed piece of the structural material has a width dimension smaller than the width of the outer surface, and nails and tapping screws are used. It preferably has a width and thickness that can be driven.

  The attachment piece of the structural material is configured so that the side bracket of the shutter can be fixed directly or via a shutter support member. The side bracket is arranged in a direction substantially orthogonal to the outer surface of the vertical frame of the window. For this reason, it is preferable that the structural material is formed so that a cross section is formed in an L shape or a T shape, and one piece can function as a fixing piece and the other piece can function as an attachment piece.

  In the present invention, the shutter does not have a special specification for retrofitting to the window, but uses an existing standardized shutter. When this shutter is retrofitted to the window, the shutter box is installed with its back face facing the outer surface of the outer wall, and a gap is generated between the shutter vertical frame of the shutter and the outer surface of the outer wall.

  In addition, in the existing windows of buildings, there is no guarantee that the outer surface of the vertical frame of the window is necessarily in the same plane as the outer wall surface, and the outer surface of the vertical frame of the window is retracted indoors from the outer surface of the outer wall. There may be. In this case, a gap between the outer surface of the outer wall and the outer surface of the window vertical frame is added between the vertical frame of the window and the shutter vertical frame in addition to the gap between the shutter vertical frame and the outer surface of the outer wall. A gap is generated.

  For this reason, it is preferable to cope with the gap by appropriately setting the protruding dimension of the mounting piece in the structural material. By attaching a closing member for directly or indirectly closing the gap to the mounting piece, it is possible to close the gap generated between the shutter and the window of any size.

  In particular, it is possible to appropriately set the dimension from the vertical frame of the window to the slat surface of the shutter by appropriately setting the protruding dimension of the mounting piece in the structural material. For this reason, the shutter can be fixed to the vertical frame of the window regardless of the shape and structure of the window.

  The closing member that closes the gap formed between the window and the shutter closes the vertical closing member that closes between the vertical frame of the window and the shutter vertical frame, and the space between the lower horizontal frame of the window and the shutter lower frame. And a lower closing member. In particular, the lower blocking member may act on the body weight when a person goes in and out of the upper part, or a flower pot or the like may be placed on the upper part to act on the load. It is preferable to have.

  For this reason, it is preferable that the surface which opposes the lower horizontal frame of the window to which a lower blocking member is attached has a shape corresponding to the shape of the outer surface of the lower horizontal frame. That is, when the window has a flat outer surface such as a wooden joinery or steel sash, the lower closing member is also configured with a flat surface. It is preferable to configure so that it can be brought into contact and fixed using a nail or a tapping screw.

  In addition, when the window is made of an aluminum sash, a groove for attaching a draining material or a shutter rail is often formed in the lower horizontal frame, and the shape and dimensions of this groove differ depending on the sash manufacturer. Is. For this reason, it is preferable that the surface facing the lower horizontal frame of the window of the lower closing member has a shape corresponding to the shape of the outer surface of the opposed lower horizontal frame. As described above, by making the shape of the surface of the lower closing member facing the lower horizontal frame of the window corresponding to the shape of the lower horizontal frame, smooth attachment can be realized.

  As described above, when the surface of the lower closing member facing the lower horizontal frame of the window corresponds to the outer surface shape of the lower horizontal frame, the other surface corresponds to the shape of the surface of the lower shutter frame facing the window. Constructed with a shape. As described above, various types of lower closing members are prepared according to the lower horizontal frame of the window, but production management and inventory management are easier than preparing the shutter lower frame according to the lower horizontal frame of the window. Become.

  Moreover, it is preferable that the vertical closing member is arranged so as to cover the structural material fixed to the vertical frame of the window and can be fixed to the structural material. In this way, by fixing the vertical closing member to the structural material, it becomes possible to have an independent shape regardless of the shape of the vertical frame of the window.

  When fixing the side bracket directly to the mounting piece of the structural material, the structural material has a length that is approximately the same as the vertical frame of the window, but the upper end of the mounting piece reaches the shutter box located at the top of the window It is configured with a possible length. In other words, the structural material is formed in an L-shaped or T-shaped cross section at a portion substantially equal to the length of the vertical frame of the window, and only a mounting piece is extended at a portion located above the vertical frame of the window. It becomes. In this case, it is preferable that the extension portion of the mounting piece has a shape of a joint portion with the side bracket of the shutter (for example, when the side bracket is a flat plate, the extension portion has the same shape as the flat bar).

  In addition, when the shutter support member is interposed when fixing the mounting piece of the structural material and the side bracket of the shutter, the structural material is configured with a length that takes into account the length of the shutter support member. The material is preferably approximately the same length as the vertical frame of the window.

  In particular, by configuring the shutter support member with a length that extends downward from the lower end of the side bracket, it is possible to adjust the length of the connecting portion between the shutter support member and the mounting piece, and the stable It is possible to realize a support structure.

  Furthermore, by appropriately setting the length of the shutter support member, the height relationship between the upper end of the existing window and the shutter box in the building can be adjusted. For example, when an existing window in a building is a window with a space, the shutter box should be placed above the upper end of the space, and the shutter corresponding to this height is selected. However, if the upper end of the column is close to the eaves and the shutter box cannot be placed in between, the shutter box must be installed at a position corresponding to the column, and the standard height is adjusted. It will be necessary. In such a case, it is preferable to fix the structural material and the side bracket via the shutter support member because the dimensions can be easily adjusted.

  When fixing the side bracket to the structural material, it is not limited whether the two are fixed directly or via the shutter support member. The height of the window, the weight of the shutter, or the window to which the shutter is to be attached It is preferable to set appropriately according to the structure around the.

  The shutter vertical frame constituting the shutter may hold the state where the upper end portion is fixed to the side bracket and suspended. However, it is preferable that the structure member can be supported via the intermediate member. The shape of the intermediate member is not particularly limited, and is preferably a shape that can be supported by being fixed to the attachment piece or the fixed piece of the structural material and can support the shutter vertical frame.

  Hereinafter, embodiments of a shutter fixing structure will be described with reference to the drawings. FIG. 1 is a development view of a fixing structure according to the present embodiment. FIG. 2 is a plan sectional view for explaining the fixing structure of this embodiment. FIG. 3 is a longitudinal sectional view for explaining the fixing structure of this embodiment. FIG. 4 is a diagram illustrating an example of the type of the lower closing member.

  In this embodiment, the window to which the shutter A is attached is configured as an existing aluminum sash B installed in a building, and the outer surface of the sash B is disposed in the same plane as the outer surface of the outer wall C. It has a structure.

  The sash B includes a pair of sash vertical frames 1 and 2, a sash upper horizontal frame 3, and a sash lower horizontal frame 4, and each frame 1 to 4 is fixed to a frame (frame) (not shown). . The outer surface of each frame 1-4 is arrange | positioned in the substantially same surface as the outer surface of the outer wall C, and the sealing 5 is constructed in the connection part of this outer wall C and each frame 1-4, and the waterproof process is made | formed. .

  Grooves 1a and 2a are formed on the outer surfaces of the sash vertical frames 1 and 2 over the entire length in the vertical direction, and a plurality of bolts 6a are slidably fitted in the grooves 1a and 2a. The structural material 11 is fixed to the sash vertical frames 1 and 2 using the bolt 6a and the nut 6b.

  In this embodiment, since the grooves 1a and 2a are formed in the vertical direction of the sash vertical frames 1 and 2, the bolts 6a are slidably fitted using the grooves 1a and 2a. In the case of a vertical frame in which is not formed, the structural material 11 can be directly fixed by a nail or a tapping screw.

  The structural material 11 stands up from the fixed piece 11a and the fixed piece 11a fixed to these sash vertical frames 1 and 2 using the bolt 6a fitted to the grooves 1a and 2a of the sash vertical frames 1 and 2. A mounting piece 11b formed in advance and having a preset extension dimension and an intermediate member 15 that is formed upright from the side opposite to the side on which the mounting piece 11b of the fixed piece 11a is erected and supports the shutter vertical frame are attached. An intermediate member fixing piece 11c and a guide piece 11d that protrudes from the surface of the mounting piece 11b opposite to the fixing piece 11a and serves as a guide when the vertical closing member 16 is attached are configured.

  The structural material 11 has a substantially the same length as the sash vertical frames 1 and 2, and a sufficiently thick steel plate is bent into a groove shape to form a fixing piece 11a, an attachment piece 11b, and an intermediate member fixing piece 11c. The guide piece 11d is configured by integrating steel plates bent in an L shape by means such as spot welding.

  In this embodiment, the structural member 11 is fixed to the sash vertical frames 1 and 2 of the sash B by bolts 6a and nuts 6b. For this reason, the fixed piece 11a is formed with a number of bolt holes (not shown) set in advance in consideration of conditions such as the length of the sash vertical frames 1 and 2 and the weight of the shutter A to be attached.

  Further, the side bracket 32 a disposed in the shutter box 31 of the shutter A is connected to the attachment piece 11 b of the structural material 11. The connection structure of the side bracket 32a with respect to the attachment piece 11b is not particularly limited, and it is possible to selectively employ welding or fastening with bolts. However, it is preferable to use bolts in consideration of workability problems at the construction site and mounting accuracy. For this reason, a plurality of bolt holes 11e are formed in advance at a predetermined position on the upper end side of the mounting piece 11b.

  As described above, in the present invention, the attachment piece 11b of the structural material 11 and the side bracket 32a of the shutter A may be directly connected or may be connected via the shutter support member. In this embodiment, they are connected via the shutter support member 12, but when both are directly connected, a plurality of bolt holes are formed at positions where the upper end of the mounting piece 11b and the side bracket 32a face each other. It is necessary to keep it.

  In this embodiment, the shutter support member 12 is made of a steel plate bent in a U-shape, and includes a shutter box 31, a pair of shutter vertical frames 37 supported by being connected to the shutter box 31, and a shutter lower frame. The shutter A is configured to have sufficient strength and rigidity to stably support the weight of the shutter A including 38.

  Further, the lower end side of the shutter support member 12 extends sufficiently below the lower end of the side bracket 32a. By attaching this extended portion to the attachment piece 11b of the structural material 11, the weight of the shutter A is increased to the structural material 11. Configured to communicate.

  Both ends of the lower closing member 18 in the longitudinal direction (left and right direction of the sash B) are fixed to the lower end of the intermediate member 15 via the bracket 17, and the sash B in the width direction (the direction of entering and exiting the sash B). The projections 18b and 18c are fitted and attached to the grooves 4a and 4b formed on the outer surface of the lower sash frame 4, and a surface 18d opposite to the surface 18a facing the sash B is provided on the shutter lower frame 38. It is engaged and fixed to the engaging part 38a formed in this.

  Therefore, the entire circumference of the lower closing member 18 is supported by the sash lower horizontal frame 4, the intermediate member 15, and the shutter lower frame, and can sufficiently withstand even if a large load (for example, adult weight) acts. It is configured as possible.

  In the shutter A of the present embodiment, a shutter box 31 is disposed at the top, and a frame 32 having a pair of side brackets 32 a is disposed in the shutter box 31. Further, a bearing (not shown) is attached to the side bracket 32a, and a winding shaft 33 for winding the slat 34 is supported on the bearing.

  A motor 35a is disposed at a predetermined position on one side in the width direction of the shutter box 31, and is connected to a sprocket wheel 35c attached to the take-up shaft 33 via a chain 35b. Therefore, by driving the motor 35a counterclockwise or clockwise, the slat 34 can be rewound to close the shutter A, or the slat 34 can be rolled up to open the shutter A.

  The upper end portions of the shutter vertical frame 37 are connected to the left and right sides of the shutter box 31 and hang down. The lower end portions of the shutter vertical frame 37 are connected to each other by the shutter lower frame 38. Guide grooves 37a for guiding the movement of the slats 34 when the shutters are opened and closed are formed on the mutually opposing surfaces of the pair of shutter vertical frames 37, and both left and right end portions of the slats 34 are fitted in the guide grooves 37a, respectively. By moving up and down together, it is configured so that smooth opening and closing can be realized.

  Since the winding diameter of the slat 34 wound around the winding shaft 33 changes in accordance with the length of the wound slat 34, the introduction when the slat 34 is introduced into the guide groove 37a of the slat 34 along with this change. The angle also changes. For this reason, the relative positions of the winding shaft 33 and the guide groove 37a are set so that smooth winding and unwinding of the slat 34 can be realized. As a result, the center of the winding shaft 33 and the guide groove 37a do not coincide with each other, and the center of the winding shaft 33 is located closer to the back surface than the guide groove 37a. Therefore, in the shutter A, the back surface of the shutter box 31 has a shape protruding toward the indoor side of the building from the shutter vertical frame 37.

  The shutter A composed of a series of parts from the shutter box 31 to the shutter lower frame 38 described above is configured as an electric shutter made of a standard product that is attached to a housing corresponding to a window when a building is newly constructed.

  Next, a structure for attaching the shutter A to the sash B will be described. First, a plurality of bolts 6a are fitted in the grooves 1a and 2a formed on the outer surfaces of the sash vertical frames 1 and 2 of the sash B, and the bolts 6a are formed on the fixing pieces 11a of the structural material 11 (not shown). The structural member 11 is fixed to the sash vertical frames 1 and 2 of the sash B by inserting the bolt holes and fastening the nuts 6b. In this state, the attachment piece 11b of the structural member 11 maintains the posture of standing up from the sash B toward the outdoor direction.

  The shutter support member 12 is fixed to the pair of side brackets 32a constituting the shutter A in advance. The lower end side of the shutter support member 12 extends sufficiently below the lower end of the side bracket 32a, and a plurality of nuts 25a are fixed to the extended portion by means such as welding.

  A plurality of bolt holes 11 e are formed in the upper end portion of the structural material 11 so as to correspond to the nuts 25 a fixed to the shutter support member 12. In particular, the bolt hole 11e is formed as a long hole, and the mounting height of the shutter box A with respect to the mounting piece 11b can be adjusted within the range of the long hole. Therefore, it is possible to adjust the height position of the shutter box 31 with respect to the upper portion of the sash B.

  As described above, the shutter support member 12 to which the side bracket 32a is fixed is opposed to the mounting piece 11b of the structural material 11, and the height of the shutter box 31 is adjusted, and then the bolt 25b is fastened to the nut 25a. The shutter box 31 is attached to the structural material 11.

  After the shutter support member 12 is fixed to the attachment piece 11 b of the structural material 11 and the shutter box 31 is attached, the vertical closing member 16 is attached to the outside of each structural material 11. The vertical closing member 16 is made of aluminum and has a cross section having a closing portion 16a, a fixed piece 16b fixed to the mounting piece 11b of the structural material 11, and an attachment piece 16c to which the intermediate member 15 and the shutter vertical frame 37 are attached. Is configured in a substantially U-shape. The fixing piece 16b is attached to the structural member 11 by being along the guide piece 11d provided on the attachment piece 11b and being fixed to the attachment piece 11b with screws 26.

  After the pair of left and right vertical blocking members 16 are attached to the structural material 11, the intermediate members 15 are attached to the inside of the structural material 11. The intermediate member 15 is made of aluminum and has a cross section having a main body portion 15a and a mounting portion 15b that is connected to the mounting piece 16c of the vertical closing member 16 and is formed in a substantially C shape for mounting the shutter vertical frame 37. Is formed in a shape in which a protruding piece stands from the groove-side web.

  Then, the end of the main body 15a is brought into contact with the intermediate member mounting piece 11c formed on the structural member 11 and connected by a screw 26, and the mounting piece 15b is connected to the mounting piece 16c of the longitudinal closing member 16 by a screw 26. And attached to the structural member 11. In this state, the attachment portion 15b of the intermediate member 15 protrudes in a C shape toward the outdoor side.

  As described above, the structural member 11 is arranged in the center, and the vertical closing member 16 is attached to the attachment piece 11b of the structural member 11, and the intermediate member 15 is attached to the intermediate member attachment piece 11c of the structural member 11. When the attachment portion 15 b of the intermediate member 15 is connected to the attachment piece 16 c of the member 16, each pipe-like column is constituted by the longitudinal closing member 15 and the intermediate member 15 around the structural material 11. As a result, a member having high rigidity in addition to the strength of the structural member 11 is formed, and it is possible to maintain a stable strength over a long period of time.

  Next, a lower closing member 18 in which L-shaped brackets 17 are inserted at both ends is disposed at the lower end portion of the intermediate member 15 and attached to the sash lower horizontal frame 4 of the sash B and the intermediate member 15. The lower closing member 18 is formed as a hollow material by an aluminum profile, and the surface 18a facing the sash lower horizontal frame 4 is engaged with the grooves 4a and 4b formed on the outer surface of the sash lower horizontal frame 4. Protruding projections 18b and 18c are formed. A fixing piece 18e fixed to the attachment piece 38a formed on the shutter lower frame 38 is formed on the surface 18d opposite to the surface 18a.

  Then, the protrusions 18b and 18c are fitted and locked in the grooves 4a and 4b of the sash lower horizontal frame 4, and the bracket 17 is connected to the lower end portion of the intermediate member 15 by the screw 26, and the sash lower horizontal frame 4 by the screw 26. Also connect to. In this state, the lower closing member 18 is connected to a stable member on each of the three side surfaces, and can sufficiently withstand even when a load including a human weight acts on the upper surface.

  As described above, the shutter box 31, the vertical closing member 16, and the intermediate member 15 are respectively attached to the structural material 11 fixed to the sash vertical frames 1 and 2 of the sash B via the shutter support member 12. A lower closing member 18 is connected to the horizontal frame 4 and the intermediate member 15. Then, the mounting portion 15b of the intermediate member 15 projects in a C shape on the surface on the outdoor side, and the fixed piece 18e of the lower closing member 18 is exposed, so that the base of the shutter vertical frame 37 and the shutter lower frame 38 is configured. It will be.

  Therefore, it is possible to attach the upper end of the shutter vertical frame 37 by connecting it to the side bracket 32a disposed in the shutter box 31 and engaging the attachment portion 15b of the intermediate member 15 with the screw 26. . Furthermore, the fixing piece 38 a of the shutter lower frame 38 can be attached by engaging with the fixing piece 18 e of the lower closing member 18 and connecting with the screw 26.

  As described above, the shutter A can be retrofitted to the existing sash B of the building. Then, after the shutter A is retrofitted, it is possible to prevent water leakage by constructing the sealing 5 in the gap between the shutter box 31 and the outer wall C. And finishing is performed by constructing the cap 27 on the outer surface of the lower closing member 18.

  Next, an example of the shape of the outer surface of the sash lower horizontal frame 4 of the sash B will be described with reference to FIG.
