Description

  TECHNICAL FIELD The present invention relates to an inner wall heat insulation panel used for renovation that stretches over an existing inner wall of a building, and a heat insulation reforming method using the inner wall heat insulation panel.

  As a method of heat insulation reform that improves the heat insulation performance of a building, there is an external heat insulation method in which a heat insulation panel is pasted on the outdoor side of an existing outer wall. In the case of a building with a specification that is not originally an outer insulation method, the outer insulation method is to install a heat insulating material on the outside of the ventilation layer on the outer wall. In addition, it is difficult to carry out renovation work, and there are many cases in which large-scale construction is required because a scaffold is required outdoors.

  Thus, various methods for the heat insulation reforming have been proposed, such as an internal heat insulating method in which a heat insulating material is additionally stretched on the indoor side (for example, Patent Document 1, Patent Document 2, and Patent Document 3). In such an insulative thermal insulation method, in order to shorten the construction period and reduce labor, a thermal insulation panel incorporating a plate-like thermal insulation material is prepared in advance in the frame of the wood base material. In many cases, a construction method in which the heat insulating panel is sequentially stretched on the inner wall is used (for example, Patent Document 1).

  By the way, since the building to be heat-insulated and remodeled has different ceiling heights and window layouts at each site, even when preparing a heat-insulating panel that incorporates a plate-like heat-insulating material in advance in the frame of the wood base material as described above, It is necessary to adjust the width and height of the insulation panel. However, since the wood base material rotates around the four circumferences of the heat insulation panel, when the heat insulation panel is cut, the work of fixing the wood base material to the end portion of the cut heat insulation panel is required.

  Further, a plurality of heat insulating panels are arranged on the indoor side of the inner wall so as to be adjacent to each other on the left and right or top and bottom, but since the wood base material is provided on the four sides of the heat insulating panel, the end of each heat insulating panel Since the wood base material fixed to the portion is arranged so as to be adjacent to each other, the wood base material is disposed more than necessary, and the portion where the heat insulating material is not provided is increased and the heat insulating performance is lowered.

  Hereinafter, the best embodiment of the inner wall heat insulation panel and heat insulation reforming method concerning the present invention is described, referring to each figure. The inner wall heat insulation panel of the present embodiment is an inner wall heat insulation panel that is extended to the indoor side of the existing inner wall 6 of the building during the heat insulation reform. A plurality of inner wall heat insulation panels having different dimensions depending on the position to be fixed are prepared, but when roughly divided, the first inner wall heat insulation panel 1 provided with an outer peripheral base frame on the right side when viewed from the lower side and the indoor side And the second inner wall heat insulating panel 2 in which the outer peripheral base frame is provided only on the lower side. Each will be described below.

[First inner wall insulation panel]
First, the 1st inner wall heat insulation panel 1 is demonstrated based on FIGS. 1-3. The first inner wall heat insulation panel 1 is a rectangular flat plate heat insulation board 3 divided into right and left two sheets, an intermediate base frame 4 provided in the height direction between the left and right heat insulation boards 3, and a first inner wall heat insulation panel. 1 is provided with an outer peripheral base frame 5 provided on the right side when viewed from the lower side and the indoor side, and a moisture-proof sheet covering these.

  The first inner wall heat insulation panel 1 has a length of, for example, about 2500 mm so that the length in the height direction can cover almost the entire height of the ceiling from the floor of the existing inner wall 6, and the length in the width direction is Although it depends on the pitch of the base material of the existing inner wall 6 that serves as a base for fixing the first inner wall heat insulating panel 1, it is, for example, about 1000 mm. The height and the length in the width direction of the first inner wall heat insulation panel 1 are determined in consideration of easiness of fixing according to the specifications of the existing inner wall 6 of the building.

  The heat insulation board 3 is a rectangular flat plate obtained by foaming and curing a phenol resin, for example. The heat insulating board 3 is not limited to this, and may be, for example, glass wool, rock wool, vacuum heat insulating material or the like. Preferably, a material such as polystyrene, polyurethane, or phenol resin is foam-cured. A foam-based heat insulating material is preferred. Since it is a heat insulation panel arranged behind the gypsum board on the inner wall, even if screws or the like are driven in, the heat insulation performance is not greatly reduced, and the heat insulation board 3 itself has a hardness that can maintain the shape. It is preferable that

  Each of the intermediate base frame 4 and the outer peripheral base frame 5 is a wooden square member having the same thickness as that of the heat insulating board 3. The intermediate base frame 4 and the outer peripheral base frame 5 on the right side have the same length as the length in the height direction of the heat insulating board 3, and the lower peripheral peripheral base frame 5 has two heat insulating boards 3, the intermediate base frame 4, and the right side outer periphery. The base frame 5 is formed by adding a length in the width direction. The intermediate base frame 4 and the outer peripheral base frame 5 on the right side are fixed to the lower peripheral base frame 5 with nails (not shown), and the heat insulating boards 3 are arranged on both sides of the intermediate base frame 4. And the surface of the panel formed with the intermediate | middle base frame 4, the outer periphery base frame 5, and the heat insulation board 3 is covered with a moisture-proof sheet, and the 1st inner wall heat insulation panel 1 is formed.

  In addition, the 1st inner wall heat insulation panel 1 is arrange | positioned between the heat insulation boards 3 by which the intermediate | middle base frame 4 was not limited to one, and the 2 or more intermediate | middle base frames 4 were each divided | segmented into 3 or more pieces. It may be a configuration. Moreover, as shown in FIG. 2, the intermediate | middle base frame 4 does not need to be provided in the 1st inner wall heat insulation panel 1 at all. For example, when the width | variety of the 1st inner wall heat insulation panel 1 is about 500 mm, it is not necessary to provide the intermediate | middle base frame 4 as a base | substrate which fixes a gypsum board.

  Moreover, the outer periphery base frame 5 of the 1st inner wall heat insulation panel 1 is not limited to what is provided in a right side and a lower side, Depending on the relationship with another heat insulating material, it changes into a right side and the outer periphery base frame 5 on the left side. Alternatively, the outer peripheral base frame 5 may be provided on the upper side instead of the lower side.

  In the present embodiment, the intermediate base frame 4 is provided such that the length direction thereof faces the height direction of the first inner wall heat insulation panel 1, but is not limited to this. When the base material provided inside the inner wall 6 is a vertical base material, the intermediate base frame 4 is preferably provided so as to face the width direction of the first inner wall heat insulating panel 1. That is, when the horizontal base material 61 is provided on the existing inner wall 6, the intermediate base frame 4 is provided with the intermediate base frame 4 facing the height direction, so that the horizontal base material can be seen from the indoor side. 61 and the intermediate base frame 4 are orthogonal to each other and a vertical base material is provided on the existing inner wall 6, the vertical base material is provided so as to face the width direction of the intermediate base frame 4 as viewed from the indoor side. Since the material and the intermediate base frame 4 are orthogonal to each other, the first inner wall heat insulation panel 1 can be securely fixed to the base material by driving a screw 7 into the orthogonal part.

  The thickness of the first inner wall heat insulation panel 1 is prepared in two types, for example, 50 mm as shown in FIG. 1 and 25 mm as shown in FIG. Since the first inner wall heat insulation panel 1 is disposed on the indoor side of the existing inner wall 6, the new inner wall after renovation is the indoor side by the thickness of the first inner wall heat insulation panel 1 and the thickness of the gypsum board 8. Hang out. Therefore, for example, it is thin in a Japanese-style room where folding is provided up to the wall of the existing inner wall 6, a entrance hall in which a container is built on the existing inner wall 6, or a portion where there is not much room between the existing inner wall 6 and the hinged door. The first inner wall heat insulation panel 1 is used, and the thick first inner wall heat insulation panel 1 having a higher heat insulation performance is provided at a place where there is less possibility of interference with other members even if the amount of the inner wall protruding to the indoor side is relatively increased. By using, the heat insulation performance as the whole building can be improved.

[Second inner wall insulation panel]
Next, the second inner wall heat insulation panel 2 will be described with reference to FIG. As shown in FIG. 4 (A), the second inner wall heat insulation panel 2 is a rectangular flat plate-shaped heat insulation board 3 that is divided into two pieces on the left and right sides, and an intermediate portion provided between the left and right heat insulation boards 3 in the height direction. The base frame 4, the outer periphery base frame 5 provided in the lower side of the 2nd inner wall heat insulation panel 2, and the waterproof sheet which covers these are provided.

  In the present embodiment, the second inner wall heat insulation panel 2 is a heat insulation panel that is stretched over the existing inner wall 6 on the upper side or the lower side of the opening 99 such as a building window. Since a pair of opening vertical members 91 facing in the vertical direction are provided on both sides of the opening 9 in order to support the added frame and sash, the second inner wall heat insulating panel 2 has the outer peripheral base frame 5 on the left and right sides. Not provided.

  The second inner wall heat insulation panel 2 has a length in the height direction that covers from the floor of the existing inner wall 6 to the lower end of the opening 9 or a length that covers from the ceiling of the existing inner wall 6 to the upper end of the opening 9. Is formed. Further, the second inner wall heat insulating panel 2 is formed to have a width slightly smaller than 1000 mm and fits between the opening vertical members 91 without a gap. In addition, the height of the 2nd inner wall heat insulation panel 2 and the length of the width direction are determined according to the installation position, fittings, and the specification of the existing inner wall 6.

  Since the heat insulation board 3 is the same material as the 1st inner wall heat insulation panel 1, description is abbreviate | omitted. Each of the intermediate base frame 4 and the outer peripheral base frame 5 is a wooden square member having the same thickness as that of the heat insulating board 3. The intermediate base frame 4 has the same length as the length of the heat insulating board 3, and the outer peripheral base frame 5 provided on the lower side is obtained by adding the length of the two heat insulating boards 3 and the intermediate base frame 4 in the width direction. It is formed in length. The intermediate base frame 4 is fixed to the lower peripheral base frame 5 with nails (not shown), and the heat insulating boards 3 are disposed on both sides of the intermediate base frame 4. And the surface of the panel formed with the intermediate | middle base frame 4, the outer periphery base frame 5, and the heat insulation board 3 is covered with a moisture-proof sheet, and the 2nd inner wall heat insulation panel 2 is formed.

  In addition, the 2nd inner wall heat insulation panel 2 is not limited to the intermediate | middle base frame 4 similarly to the 1st inner wall heat insulation panel 1, The two or more intermediate | middle base frames 4 may be provided. Further, as shown in FIG. 4 (B), the second inner wall heat insulation panel 2 may not have the intermediate base frame 4 at all.

  Moreover, as shown in FIG.4 (C) (D), the 2nd inner wall heat insulation panel 2 may affix the reinforcement plywood 21 on the indoor side surface beforehand depending on the position to install. For example, since the second inner wall heat insulation panel 2 disposed on the upper side of the opening 9 needs to be attached with a curtain tail after the heat insulation reforming, the reinforcing plywood 21 is necessarily required inside the wall of the gypsum board 8. Therefore, the reinforcing plywood 21 may be fixed to the surface on the indoor side in advance in the second inner wall heat insulation panel 2 disposed above the opening 9. In addition, even if it is other than the upper side of the opening 9, for example, the reinforcing plywood 21 may be fixed in advance to a place requiring reinforcement such as an air conditioner installation surface or a handrail installation surface of the first inner wall insulation panel 1 or the second inner wall insulation panel 2. Alternatively, the reinforcing plywood 21 may be fixed when performing construction on site. When the reinforcing plywood 21 is fixed in advance, there is an advantage that the work process at the renovation site is simplified to reduce the labor and the work period, and when the reinforcing plywood 21 is fixed at the site, the number of parts is reduced. There are advantages.

[Insulation reforming method]
Next, a heat insulation reforming method using the first inner wall heat insulation panel 1 and the second inner wall heat insulation panel 2 formed as described above will be described with reference to FIGS. In the heat insulation reforming method of the present embodiment, first, as shown in FIGS. 5 and 6, the cross rail 10 is fixed to the upper edge of the existing inner wall 6 with screws 7. The crosspiece 10 is a square member having the same thickness as the first inner wall heat insulation panel 1 and the second inner wall heat insulation panel 2, and is fixed to a wooden base material of the upper edge provided on the inner side of the existing inner wall 6 by screws 7. A large number of horizontal base materials 61 are provided on the inner side of the existing inner wall 6 as shown in FIG. In the present embodiment, the outer peripheral base frame 5 of the first inner wall heat insulation panel 1 is provided on the lower side. For example, the outer peripheral base frame 5 of the first inner wall heat insulation panel 1 is provided on the upper side, and the horizontal rail 10 May be fixed to the lower edge of the existing inner wall 6. The upper edge of the existing inner wall 6 refers to a position in contact with the ceiling plate 14 of the existing inner wall 6, and the lower edge of the existing inner wall 6 refers to a position in contact with the floor plate 13 of the existing inner wall 6.

  Next, as shown in FIG. 7, the corner vertical members 12 are disposed at the corners where the first first inner wall heat insulation panel 1 is disposed, and the opening vertical members 91 are disposed on both sides of the opening 9. A horizontal member 92 is disposed below the portion 9. The corner vertical member 12, the opening vertical member 91, and the horizontal member 92 are all square members formed to have the same thickness as the first inner wall heat insulating panel 1 and the second inner wall heat insulating panel 2. In addition, you may arrange | position the 1st inner wall heat insulation panel 1 in which the outer periphery base frame 5 was provided in the said corner side, without arrange | positioning the corner vertical material 12 in a corner. In addition, although not shown, when the first inner wall heat insulation panel 1 is additionally stretched on the existing inner walls 6 on both sides across the corner, the heat insulation board 3 having the same shape as the corner vertical member 12 is disposed and beside it. The structure which fixes the corner | angular part vertical material 12 may be sufficient. The opening vertical member 91 on both sides of the opening 9 and the horizontal member 92 on the lower side of the opening 9 are for adding a frame and a sash to the extent that the inner wall protrudes to the indoor side by heat insulation reform.

  Then, as shown in FIGS. 8 to 10, the first inner wall heat insulation panel 1 is disposed next to the corner vertical member 12 disposed at the corner. And the position where the outer periphery base frame 5 and the intermediate | middle base frame 4 of the 1st inner wall heat insulation panel 1 orthogonally cross with the horizontal base material 61 provided inside the wall of the existing inner wall 6 is fixed with the bis | screw 7. FIG. Further, the first inner wall heat insulation panel 1 is disposed adjacent to the fixed first inner wall heat insulation panel 1 as shown in FIG. 11, and the outer base frame 5 and the intermediate base frame 4 are orthogonal to the horizontal base material 61. Is fixed with screws 7.

  The first inner wall heat insulation panel 1 is provided with an outer peripheral base frame 5 on the right side and the lower side, the right side of the adjacent first inner wall heat insulation panel 1 is disposed on the left side, and a horizontal rail 10 is provided on the upper side. Therefore, after installing the 1st inner wall heat insulation panel 1 in the existing inner wall 6, the four circumferences are surrounded by the square material, and it can be used as the foundation | substrate which fixes the gypsum board 8 later.

  In addition, when the height and width of the ceiling of the existing inner wall 6 do not match the dimensions of the first inner wall heat insulation panel 1, as shown in FIGS. 12 (A) and 12 (B), the outer peripheral base frame of the first inner wall heat insulation panel 1 The upper side or the left side where 5 is not provided is cut to adjust the dimensions of the first inner wall heat insulation panel 1. Since the outer peripheral base frame 5 is not provided on the upper side and the left side of the first inner wall heat insulating panel 1, even if these are cut, the outer peripheral base frame 5 is only cut at the upper end or part of the left end. After fixing the inner wall heat insulating panel 1, the outer peripheral base frame 5 can sufficiently function as a base for fixing the gypsum board 8.

  When the first inner wall insulating panel 1 is fixed to the existing inner wall 6, the second inner wall insulating panel 2 is then fixed to the existing inner walls 6 above and below the opening 9 as shown in FIGS. 13 and 14. In this embodiment, an example in which the existing inner wall 6 is provided above and below the opening 9 is shown. However, the existing inner wall 6 is provided only above the opening 9 as in the case of a sweep window, for example. If not, the second inner wall heat insulation panel 2 is fixed to the existing inner wall 6 above the opening 9.

  The second inner wall heat insulating panel 2 is fitted with the second inner wall heat insulating panel 2 between the opening vertical members 91 on both sides, and the horizontal base material 61 provided on the inner side of the existing inner wall 6 and the outer periphery of the intermediate base material and the lower side. The base material is fixed with screws 7. Reinforcing plywood 21 is fixed in advance to the second inner wall heat insulation panel 2 provided on the upper side of the opening 9, and the reinforcing plywood 21 and the opening vertical material 91 are fixed to the opening vertical material 91 on both sides. The receiving part 93 is fixed. After the second inner wall heat insulating panel 2 is fixed, the reinforcing plywood 21 is fixed to the receiving portion 93 with screws.

  When the first inner wall heat insulating panel 1 and the second inner wall heat insulating panel 2 are fixed to the existing inner wall 6, next, as shown in FIGS. 15 and 16, the upper edge cross rail 10, the first inner wall heat insulating panel The gypsum board 8 is fixed to the outer peripheral base frame 5 and the intermediate base frame 4 of the first and second inner wall heat insulation panels 2 with a gypsum board fixing screw 11. And the wallpaper which is not shown in figure on the gypsum board 8 is affixed, and heat insulation reform is complete | finished.

  Thus, according to the first inner wall heat insulation panel 1, the second inner wall heat insulation panel 2, and the heat insulation reforming method of the present embodiment, the width and height of the first inner wall heat insulation panel 1 or the second inner wall heat insulation panel 2 at the renovation site. When adjusting, it can adjust easily by cut | disconnecting the side in which the outer periphery base frame 5 is not provided. Further, when a plurality of first inner wall heat insulation panels 1 are arranged adjacent to each other, the outer base frame 5 is provided at the end of one first inner wall heat insulation panel 1 while the end of the other first inner wall heat insulation panel 1 is provided. Since it is not necessary to provide the outer peripheral base frame 5, it is possible to arrange only the minimum outer peripheral base frame 5 necessary for fixing the gypsum board 8, and to improve the heat insulation performance.

  Moreover, since it is the reforming method which fixes the gypsum board 8 after fixing the 1st inner wall heat insulation panel 1 to the existing inner wall 6, compared with the method of fixing the gypsum board 8 to the 1st inner wall heat insulation panel 1 previously, it is construction. The front first inner wall heat insulation panel 1 can be reduced in weight, and is excellent in handling during renovation work. Moreover, adjustment of the width | variety and height of the 1st inner wall heat insulation panel 1 can be easily performed because the gypsum board 8 is not sticking. Further, for example, when it is desired to reinforce the inner wall in order to install a handrail, an air conditioner, a floor decoration, etc., the plywood can be easily fixed between the first inner wall insulating panel and the gypsum board 8.

  Needless to say, the embodiment of the present invention is not limited to the above-described embodiment, and can be appropriately changed without departing from the scope of the idea of the present invention.

  The inner wall heat insulation panel and the heat insulation reforming method according to the present invention can be suitably used as, for example, a heat insulation panel and a heat insulation reforming method used for heat insulation reform of a house.
