DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] [Embodiment] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The wall 1 of the building shown in Figures 1 and 2 comprises a skeleton 11 having an opening 1A, an inner wall 12, for example made of gypsum board, fixed to the interior side of the skeleton 11 except for the opening 1A, and an outer wall 13 fixed to the exterior side of the skeleton 11 except for the opening 1A. The skeleton 11 comprises an opening frame 114 made up of a lintel 111, a window sill 112, and left and right vertical members 113. Spacers 115 are attached to the opposing surfaces of the opening frame 114. The opening frame 114 and the spacer 115 form the opening 1A. An outer window 2, a frame 5, and an inner window 6 are attached to the opening 1A.

[0011] The exterior window 2 comprises an exterior window frame 3 and a pair of shoji screens 4 supported by the exterior window frame 3. The exterior window frame 3 is composed of an upper frame 31, a lower frame 32, and left and right vertical frames 33, each formed from an aluminum extrusion, and is screwed to a spacer 115 and an opening frame 114 at different positions. The pair of shoji screens 4 are composed of an upper frame 41, a lower frame 42, left and right vertical frames 43, each formed from an aluminum extrusion, and a single-pane glass panel 44 (face material) assembled together. The exterior window 2 is a sliding window in which the pair of shoji screens 4 are supported inside the exterior window frame 3 in a left-right sliding manner so that they can be opened and closed. The frame 5 comprises an upper frame material 51, a lower frame material 52 and left and right vertical frame materials 53, and is screwed to the outer window frame 3 so as to protrude from the inner wall 12 toward the inside of the room.

[0012] The inner window 6 comprises an inner window frame 61 fixed to the inner periphery of the frame 5 so as to protrude from the frame 5 toward the inside of the room, and a pair of shoji screens 62 supported by the inner window frame 61. The inner window frame 61 has an upper frame 63, a lower frame 64, and left and right vertical frames 65 all made of resin, and the pair of shoji screens 62 are each constructed by assembling an upper frame 66, a lower frame 67, left and right vertical frames 68, and double-glazed glass 69, all made of resin. The upper frame 63 includes an upper frame body 631 screwed to the upper frame material 51 and the spacer 115, and a pair of upper rail members 632 screwed to the underside of the upper frame body 631 and fitted into grooves at the upper ends of the pair of shoji screens 62. The lower frame 64 includes a lower frame body 641 screwed to the lower frame material 52 and the spacer 115, and a pair of lower rail members 642 screwed to the upper surface of the lower frame body 641 and fitted into grooves at the lower ends of the pair of shoji screens 62. The vertical frame 65 is screwed to the vertical frame material 53 and the spacer 115. The inner window 6, like the outer window 2, is a sliding window (plastic window) in which a pair of shoji screens 62 are supported inside an inner window frame 61 so that they can be slid open and closed in a left-right sliding manner.

[0013] As shown in Fig. 1, Fig. 2 and Fig. 3(A), four insulation panels 7 arranged in the width direction are attached to the inner wall 12 of the wall body 1 so as to cover the entire surface of the inner wall 12. The insulation panel 7 includes a deformable insulation material 71 and a decorative panel 72 attached to one side of the insulation material 71, and is attached to the inner wall 12 via a double-sided tape (not shown) provided on the other side of the insulation material 71. The two insulation panels 7 attached around the inner window 6 are formed into a U-shaped plate shape or an inverted U-shaped plate shape by cutting the rectangular insulation panel 7, and are attached so as to cover the outer peripheral surface and the end on the room side of the frame 5, and the upper cut edge 74, the lower cut edge 75 and the horizontal cut edge 76 formed by the cutting are respectively abutted against the outer peripheral surfaces of the upper frame 63, the lower frame 64 and the vertical frame 65 of the inner window 6. The insulation panels 7 adjacent to each other are attached so that their visible surfaces are in contact with each other.

[0014] Next, a method for insulating and renovating the wall 1 will be described. First, as shown in Figs. 1 and 2, the inner window 6 is attached to the opening 1A via the frame 5 so as to protrude from the inner wall 12 of the wall body 1 to the inside of the room. Furthermore, two of the four insulation panels 7 of the same size are cut into a U-shaped or inverted U-shaped shape to match the shape of the inner window 6. Then, for example, from the left in Fig. 3(A) , the rectangular plate-shaped insulation panel 7, the inverted U-shaped insulation panel 7, the U-shaped insulation panel 7, and the rectangular plate-shaped insulation panel 7 are attached to the inner wall 12 so that their visible surfaces contact each other and so that the cut edges 74, 75, and 76 of the inverted U-shaped insulation panel 7 and the U-shaped insulation panel 7 abut the outer circumferential surface of the inner window 6.

[0015] According to the above-mentioned insulation structure and insulation renovation method for the wall 1, the insulation panel 7 is attached around the inner window 6 so that the cut edges 74, 75, 76 abut the outer peripheral surface of the inner window 6, improving the insulation performance. Also, since it is sufficient to install the inner window 6 and the insulation panel 7, it is not necessary to install an inner opening frame as in Patent Document 1, which simplifies the installation. Furthermore, since there is no inner opening frame, the protruding dimension of the inner window 6 from the inner wall 12 can be shortened. The heat insulating panel 7 is attached around the inner window 6 so as to cover the outer peripheral surface of the frame 5 and the end portion facing the room, thereby improving the design of the wall body 1.

[0016] [Variations] Although U-shaped and inverted U-shaped insulation panels 7 have been exemplified as the insulation panels 7 attached around the inner window 6, the shape is not limited to the above as long as the edges of the insulation panels abut the outer periphery of the inner window 6. For example, as shown in Fig. 3(B), two vertically long rectangular insulation panels 7A may be attached to the left and right of the inner window 6 so that their edges abut the outer periphery of the vertical frame 65, and horizontally long rectangular insulation panels 7B and 7C may be attached to the top and bottom of the inner window 6 so that their edges abut the outer periphery of the upper frame 63 and the lower frame 64, respectively. The picture frame 5 may be attached so as not to protrude from the inner wall 12 into the room.

[0017] [Summary of the invention] The insulating structure of a wall of the present invention is an insulating structure of a wall having an exterior window attached to an opening, characterized in that an interior window is attached to the opening so as to protrude from the interior wall of the wall toward the inside of the room, and an insulating panel is attached to the inner wall so that its edge abuts the outer peripheral surface of the interior window. According to the present invention, the insulation panel is attached around the inner window so that its edge abuts the outer peripheral surface of the inner window, thereby improving insulation performance and simplifying construction since it is only necessary to install the inner window and insulation panel, and there is no need to install the inner opening frame.

[0018] In the insulating structure of the wall of the present invention, it is preferable that a frame is attached to the opening so as to protrude from the inner wall toward the inside of the room, the inner window is attached inside the frame so as to protrude from the frame toward the inside of the room, and the insulating panel is attached so as to cover the outer peripheral surface of the frame and the end portion on the inside of the room. According to the present invention, the design of the wall body can be improved.

[0019] The insulation renovation method for a wall of the present invention is a method for insulation renovation of a wall having an exterior window attached to an opening, characterized in that an interior window is attached to the opening so as to protrude from the inner wall of the wall toward the inside of the room, and an insulation panel is attached to the inner wall so that its edge abuts the outer peripheral surface of the interior window. According to the present invention, it is possible to provide a method for insulating a wall body, which can improve the insulating performance and facilitate construction work.
