Description

  The present invention relates to a heat insulation reforming method for reforming an existing house so as to enhance the heat insulation effect, and a heat insulation panel for heat insulation reform used in the method.

In recent years, there are many examples in which heat insulation work is performed at the time of renovation for existing houses.
The most excellent heat insulation work is a heat insulation construction method called external heat insulation in which a heat insulating material is applied to the outer wall of the frame.
However, since the range covered by the divisional ownership is generally limited to the inside of the housing in an apartment house, external heat insulation performed outside the housing can be performed only for large-scale repairs and the like. Moreover, in a detached house, although there are no such restrictions, when performing external heat insulation, since it is necessary to perform large preparations, such as scaffold construction and protection sheet installation, it cannot be implemented easily.
Therefore, generally, when performing heat insulation work by renovation, a work for constructing a heat insulating material inside a housing called inner heat insulation is performed.
Specifically, the construction method as shown below is adopted.

(1) After removing the existing wall material, a heat insulating material such as glass wool is applied between the studs, and the wall material is applied again (or an integrated heat insulating panel is applied) (for example, Patent Documents 1, 2, 3)
This method is a very general heat insulation reforming method, and the wall thickness does not change before and after the construction, so that the room is not narrowed. Further, since the heat insulating material can be accurately applied at a predetermined position, there is little possibility that an unprocessed portion remains.

(2) A heat insulating material construction method in which an existing wall material is perforated, a urethane liquid is injected from this hole into a space behind the wall, and foamed and cured to form a heat insulating layer (for example, see Patent Document 4).
Since this method does not remove the existing wall material, it does not generate waste and can be constructed in a relatively short time. In addition, noise, vibration, dust and the like hardly occur during construction.

(3) A construction method in which a plurality of trunk edges are installed on an existing wall material, and a wall material is installed after installing a heat insulating material between the trunk edges (for example, see Patent Document 4).
Since this method does not remove the existing wall material, it does not generate waste and can be constructed in a relatively short time. In addition, noise, vibration, dust and the like hardly occur during construction.

(4) Construction method of installing a panel in which a heat insulating material and a wall material are integrated on an existing wall material (see, for example, Patent Document 5)
This method requires only a panel in which a heat insulating material and a wall material are integrated with an existing wall material, so that the construction is extremely simple and the construction time is short. A plaster board is often used as the wall material.

JP-A-55-091656 Japanese Patent Laid-Open No. 10-018462 Japanese Patent Laid-Open No. 08-093132 Japanese Patent No. 3872272 JP 2000-170278 A

However, there have been the following problems with the conventional heat insulation renovation work in existing houses.
(1) After removing the existing wall material, install the insulation material between the studs, and then re-install the wall material, remove the existing wall material, carry out the waste material, install the insulation material, construct the wall material Since there are processes, the construction time becomes longer and a large amount of waste is generated, resulting in a lot of noise, vibration, dust and the like.
In particular, when removing existing wall materials and carrying out waste materials, a dedicated waste transport vehicle comes and is generally carried out in the first stage of the renovation work. In many cases, it becomes unusable.
Therefore, construction while living requires patience for residents, so there is a risk of falling into physical health from stress, so if renovation work takes a long time, it may be recommended to move to a temporary residence . In addition, there is a problem that the neighborhood is greatly inconvenienced during the renovation work.
Furthermore, it is necessary to replace the studs where nails or the like remain with new ones in some cases.

(2) In the construction method in which the existing wall material is drilled and the urethane liquid is injected from this hole to form the heat insulation layer, it cannot be confirmed whether or not the heat insulation material has been reliably constructed. There is a risk that it will remain. Further, since the organic solvent odor is present at the stage where the urethane liquid is cured, ventilation is necessary, and it is difficult for a person who is sensitive to the organic solvent odor to reside.
In addition, because urethane has adhesive properties, wall materials, studs, wiring, and other objects that are present inside the wall are all wrapped in urethane foam and bonded together. If it is necessary to remodel at a later date, the wall It is extremely difficult to remove or replace only the material.
In addition, since urethane foam is injected by inserting a nozzle into a hole drilled in the wall, the injection position can be easily determined, and it is easy to construct and can handle complex shapes. It is extremely difficult to reach every corner, and foaming unevenness may occur depending on the position. In addition, flame retardant treatment is possible for urethane, but there is a limit because it is basically a combustible material.

(3) In the construction method in which the wall material is installed after installing the wall edge on the existing wall material, and the heat insulating material is installed between the wall edges, in order to improve the heat insulation performance, the body edge is made large and the insulation is thick between them. It is desirable to construct the material, but if it is too thick, the room will be reduced accordingly.
Glass wool is used as a heat insulating material installed between the trunk edges, but general glass wool requires a thickness of at least about 50 millimeters (mm) in order to ensure the required heat insulation performance. As a result, the room is inevitably narrowed, and the problem of fitting with the opening frame or the like also arises. Since it is clear that the heat insulation performance decreases if the glass wool is thinned, the meaning of the heat insulation reform work is lost.
In addition, glass wool is generally used in non-flammable and cheaply when it is constructed so that it is pushed by hand into gaps, etc. If it is used on a wall, it may fall off and collect at the bottom of the wall. In addition, if you handle it with bare hands, fine debris will pierce you and you will feel itchy, and if you inhale fine powder, it will be harmful. In addition, since it is fluffy, it is difficult to cut it into an accurate size, and once it gets wet during construction, it is difficult to dry, which causes mold generation and decay at a later date.

(4) In a construction method in which a panel in which a heat insulating material and a wall material are integrated is installed on an existing wall material, the structure is complicated and heavy because the number of members increases.
In addition, depending on the type of finished decorative wall material, the wall material integrated with the panel may be wasted. For example, when a plate-shaped decorative wall material is constructed, the decorative plaster board is fixed to the frame material, so the base plaster board is wasted. When a plywood (both combustible materials) is used, it is necessary to construct a non-combustible plate on the plywood, which is also wasted. And there is a problem that the room is further narrowed by this useless thickness.
In addition, plasterboards, thin plywood and MDF (thickness of about 3 to 6 millimeters (mm)) used as wall materials are not effective for nails, staples, screws, etc., and special metal fittings such as board anchors are required. There is. In particular, plasterboard is often used because it is nonflammable, but it has the disadvantage of being easily cracked and heavy.

  Accordingly, an object of the present invention is to provide a heat insulation reforming method and a heat insulation panel for heat insulation reforming which can reduce the thickness of the heat insulating material and perform a simple and high heat insulation reforming.

  In order to achieve the above object, the heat insulation reforming method according to claim 1 of the present invention includes a horizontal crosspiece (11) extending horizontally and arranged at predetermined intervals in the vertical direction, and at least the horizontal crosspiece ( 11) A heat insulating material (21, 22) having a rectangular shape and a thickness of 25 millimeters (mm) or less is integrated between the front and back surfaces of the heat insulating material (21, 22). The heat insulation panel (10) for renovation which is exposed excluding the arrangement portion of the existing wall (1) or the existing ceiling (2) on the indoor side of the existing wall (1) or the existing ceiling (2). It is characterized by being built in layers without removing.

Moreover, the heat insulation reforming heat insulation panel of Claim 2 of this invention removes the existing wall (1) or the existing ceiling (2) in the room interior side of the existing wall (1) or the existing ceiling (2). It is a heat insulation panel (10) for renovation that is applied without being overlaid,
A plurality of horizontal crosspieces (11) extending horizontally and arranged at predetermined intervals in the vertical direction, and at least a rectangular insulating material having a thickness of 25 millimeters (mm) or less arranged between the horizontal crosspieces (11) ( 21 and 22) are integrated, and the front and back surfaces of the heat insulating material (21 and 22) are exposed except for the arrangement portion of the horizontal crosspiece (11).

  Further, in the invention according to claim 3, the heat insulating material (22) is a single panel, and on the surface side thereof, a groove (22a) into which the horizontal crosspiece (11) is fitted is provided in a vertical direction. The heat insulation reforming heat insulation panel according to claim 2, wherein the heat insulation reforming heat insulation panel is provided at the predetermined interval.

  In the invention according to claim 4, the thickness of the groove (22 a) provided in the heat insulating material (22) and the horizontal crosspiece (11) fitted therein is 1 of the thickness of the heat insulating material (22). It is smaller than / 2.

  In the invention according to claim 5, the heat insulating material (21) is a plurality of panels, and the thickness of the crosspiece (11) is substantially the same as the thickness of the heat insulating material (21). And the said horizontal crosspiece (11) is provided in the up-down direction alternately, It is characterized by the above-mentioned.

  Further, in the invention according to claim 6, the heat insulating material (21) is located above the position of the uppermost horizontal pier among the horizontal piers (11) or below the position of the lowermost horizontal pier (11). , 22) exists.

  Moreover, the invention which concerns on Claim 7 arrange | positions the vertical crosspiece (12) extended up and down to the left-right both ends of the said horizontal crosspiece (11), and is integrated with the said horizontal crosspiece (11) and the said heat insulating material (21, 22). It is characterized by that.

  The invention according to claim 8 is characterized in that a material containing phenol foam is used as the heat insulating material (21, 22).

  In addition, the “heat insulating material” described in the present invention includes, for example, a member formed by covering a heat insulating material such as glass composite paper or aluminum face material pasted on the surface of phenol foam. . Therefore, “exposure” described in claims 1 and 2 does not mean that only the heat insulating material is exposed. Further, “rectangular shape” means that a square is included as well as a rectangle.

  Here, the symbols in the parentheses indicate corresponding elements or corresponding matters described in the drawings and the embodiments for carrying out the invention described later.

According to the heat insulation reforming method and the heat insulation reforming panel of the present invention, without removing the existing wall, the heat insulation reforming heat insulation panel formed by integrating the horizontal crosspiece and the heat insulating material is stacked from the indoor side of the existing wall. Insulation renovation can be performed simply by constructing, so there is no restriction on the use of bracing or electrical wiring inside the wall, and almost no waste is generated, and it takes time to remove the existing wall. Therefore, the construction is easy and the construction time is short.
In addition, the heat insulation reforming heat insulation panel is composed only of a cross pier and a heat insulating material. On the other hand, no wall material is provided so as to cover the heat insulating material, so that the weight is light and convenient for transportation. Moreover, since the wall material is not integrated, the optimal wall material can be selected and attached depending on the type of the decorative wall material after the heat insulation reforming heat insulation panel is applied to the existing wall. Moreover, it is possible to remove or replace only the wall material at a later date by remodeling or the like. In addition, plasterboard is often used as the wall material, but since plasterboard is heavy and easily broken, it is generally produced and sold in a dimension shorter than the height of the wall surface. Since the material must also be shorter than the height of the wall surface, it will be pasted on the top and bottom of the wall surface respectively, and the construction man-hours such as installing the trunk edge will increase, but in the present invention it may be of the height of the wall surface Construction is easy.
Further, in the heat insulating reforming heat insulating panel to be used, the heat insulating material is made of, for example, phenol foam and has a thickness of 25 millimeters (mm) or less. It can be 2 or less, and the room is not extremely narrow.

Further, according to the present invention, the horizontal crosspiece is fitted into the groove formed on the surface side of the heat insulating material as a single panel, so that the entire back surface side of the heat insulating reforming heat insulating panel becomes the heat insulating material. In this way, since the heat insulating material is provided continuously without a break, there is no place where the horizontal crosspiece having a higher thermal conductivity than the heat insulating material is connected from the front surface side to the back surface side of the heat insulating reforming panel. Min, heat insulation performance is enhanced.
The method for forming the groove is not particularly limited. For example, a method of forming a groove by forming a groove when a single panel is later cut to form a groove or a heat insulating material is formed. There is.

  In addition, according to the present invention, the thickness of the heat insulating material is increased because the thickness of the groove provided in the heat insulating material and the thickness of the cross beam fitted therein are made smaller than ½ of the thickness of the heat insulating material. The heat insulation performance is improved accordingly.

  Further, according to the present invention, the heat insulating material is composed of a plurality of panels, and the thickness of the horizontal pier is substantially the same as the thickness of the heat insulating material so that the panels and the horizontal pier are alternately provided in the vertical direction. In the production of the heat insulating panel for reforming, waste of the heat insulating material does not occur as compared with the case where the groove is formed from one panel.

  Further, according to the present invention, since the portion of the heat insulating material is left above the position of the uppermost horizontal pier or below the position of the lowermost horizontal pier, the portion of the uppermost heat insulating material or Slightly cutting the bottom insulation part makes it easy to make fine adjustments in the height direction, and there are some irregularities on the ceiling and floor where the top and bottom parts abut. However, the unevenness is absorbed by the flexibility (elasticity) of the heat insulating material.

  Further, according to the present invention, the vertical crosspieces extending vertically are arranged on the left and right ends of the horizontal crosspiece and integrated with the horizontal crosspiece and the heat insulating material, so that the strength of the heat insulating reforming heat insulation panel can be sufficiently maintained.

  In addition, like the heat insulation reforming method and the heat insulation reforming panel of the present invention, without removing the existing wall, the heat insulation material and the horizontal crosspiece or in addition to this, the heat insulation panel made of the vertical crosspiece is applied to the wall. The point is not described at all in Patent Documents 1 to 5 described above.

With reference to FIG.1 and FIG.2, the heat insulation reforming method using the heat insulation panel 10 for heat insulation reform which concerns on embodiment of this invention, and its heat insulation panel 10 is demonstrated.
There are various types of heat insulation panels for heat insulation reforming, for the wall 1 and for the ceiling 2, which are different in size, but are common in that a plurality of horizontal piers 11 and the heat insulating material 21 are integrated.

As shown in FIG. 1, the heat insulation reforming panel 10 for walls is composed of only the horizontal pier 11 and the heat insulating material 21, and the plurality of horizontal piers 11 and the plurality of heat insulating materials 21 are alternately arranged in the vertical direction. Is provided. Therefore, the heat insulation reforming heat insulation panel 10 is not covered with the surface of the wall material (wall base material) and the back surface, and the surface and the back surface of the heat insulation material 21 are exposed except for the portion where the horizontal pier 11 is arranged. Yes.
The horizontal crosspieces 11 extend horizontally and are arranged in a plurality at a predetermined interval S in the vertical direction, a total of seven here, and a panel-shaped heat insulating material 21 (here, six pieces) between the horizontal crosspieces 11 adjacent to the top and bottom. Is arranged. Moreover, the thickness of the horizontal crosspiece 11 and the thickness of the heat insulating material 21 are substantially the same, and the planar heat insulation panel 10 is formed as a whole.

Although each horizontal crosspiece 11 and each heat insulating material 21 are integrated with an adhesive, the heat insulating reforming heat insulating panel 10 is taken into the wall material 30 constructed thereon as shown in FIG. Therefore, it is not necessary to firmly bond these members, and it is sufficient that they are not damaged during transportation and construction.
And as a fixing method of each horizontal crosspiece 11 and each heat insulating material 21, it does not specifically limit, For example, the surface which touches is simply adhere | attached with an adhesive agent, or a thin fiber sheet like a nonwoven fabric or linen is used. Use to bond the boundary between the horizontal crosspiece 11 and the heat insulating material 21 from both the front and back sides or from one side, or place the horizontal crosspiece 11 at a predetermined interval S in the formwork and pour phenol resin or the like into the space. It may be fixed by foaming. Moreover, the horizontal crosspiece 11 and the heat insulating material 21 are fixed by using a dowel and an adhesive together, or the horizontal crosspiece 11 is provided with a thin protruding portion with staples, etc., and the heat insulating material 21 is reduced, and an adhesive is used in combination. It is also possible to fix it, or to provide a fruit on both the horizontal pier 11 and the heat insulating material 21, or to use an actual fruit and fix it together with an adhesive.

The heat insulating material 21 is excellent in flame retardancy, and has a rectangular shape (including not only a rectangular shape but also a square shape) and a thickness of 25 millimeters (mm) so that the room is not narrowed even when constructed. ) Or less, and more preferably 20 millimeters (mm) or less. Here, the heat insulating material 21 containing phenol foam having a thickness of about 15 mm is used.
This heat insulating material 21 is obtained by pasting glass composite paper on the surface of a heat insulating material called phenol foam, and has a heat insulating performance equivalent to glass wool having a thickness of about 15 millimeters (mm) and a thickness of about 50 millimeters (mm). In addition, since it is shaped like a board, it is not necessary to prepare a stepladder and push it up and down to push it near the ceiling like glass wool, and it collapses due to secular change. Insulation performance will not be reduced. Moreover, the heat insulating material 21 made of phenol foam can be cut accurately and easily with a knife, a saw, or the like, even when cutting with matching dimensions. In addition, the phenol foam is 28 to 32 when expressed by an oxygen index shown as one of the flammability indicators of the material, and is a general polystyrene foam having an oxygen index of 18 or a polyurethane foam having 20 to 21. In comparison, it has excellent flame retardancy, and phenol foam does not emit toxic gases and emits less smoke in the event of a fire.

  The heat insulation reforming heat insulation panel 10 can have a height that matches the height of the ceiling (2100 to 2400 millimeters (mm)), or 1800 millimeters (mm) that is easy to transport and handle. You can also In particular, in wooden houses in Japan, the basic module often sets the distance between pillar cores to 3 scales (909 millimeters (mm)), but there are also properties of 1000 millimeters (mm), so this and the thickness of the wall If the influence of the thickness of the sheath and floor / ceiling is taken into consideration, fine adjustment can be easily performed by cutting the portion of the heat insulating material 21 at the construction site. Further, by providing the horizontal crosspiece 11, any module and any pitch of the studs (1 scale, 1.5 scale) can be handled.

Next, a heat insulation reforming method using these heat insulation reforming heat insulation panels 10 will be described with reference to FIG. This insulation reform is performed on a room-by-room basis.
First, remove the furniture and other items from the room where the insulation is renovated.
Next, the wall 1, ceiling 2 and floor 3 of the existing interior are checked to repair defects such as peeling and breakage. In addition, this repair should just make it possible to install the heat insulation panel 10 for various heat insulation reforms vertically or horizontally, without gaps with the existing wall (existing interior wall) 1 or the like.
Appliances such as an outlet, a switch, an air conditioner, and a lighting on the wall 1 are basically removed once and then reattached after the heat insulation reforming heat insulation panel 10 is constructed. However, in some cases, it may be possible to install a thermal insulation reforming panel 10 cut around an outlet or the like.

Next, the heat insulation reforming heat insulation panel 10 is constructed. At this time, it is not necessary to remove the existing wall 1, and the heat insulation reforming heat insulation panel 10 for the wall having the same height as the existing wall 1 is directly stacked thereon.
For fixing the heat insulating reforming heat insulating panel 10 to the existing wall 1, screws, nails, staples, and finish nails are mainly used. However, key portions may be fixed with an adhesive such as urethane.

Next, a separately prepared wall material 30 is applied from above the heat insulation reforming heat insulation panel 10. When a general plaster board is used as the wall material 30, the wall material 30 is fixed to the base material (columns, studs, etc.) of the existing wall 1 with screws. Preferably, it is fixed at the position of the base material of the existing wall 1 and at the place where the horizontal pier 11 of the heat insulation panel 10 for heat insulation reform is present, but is fixed at the place where the horizontal pier 11 of the heat insulation reforming heat insulation panel 10 is not present. There may be places.
As the wall material 30, other wood materials such as plywood, fiberboard such as MDF, and LVL may be used in addition to the plaster board. Here, although the two wall materials 30 separated by the 1/3 from the upper part and the part below it were used, it is not specifically limited.
Then, after performing groundwork adjustment (not shown) such as putty filling, a wall finishing material 40 such as wallpaper is applied on the fixed wall material 30.
In addition, when a base material such as a thick panel is unnecessary as the wall material 30, the wall finishing material 40 may be directly fixed to the heat insulation reforming heat insulation panel 10.
The heat insulation renovation work is completed by the above.

According to the heat insulation reforming heat insulation panel 10 and the heat insulation reforming method configured as described above, the heat insulation reforming heat insulation panel is formed by integrating the crosspiece 11 and the heat insulation material 21 without removing the finishing material on the existing wall 1. Since it is possible to carry out insulation reform simply by stacking from the indoor side of the existing wall, there is almost no waste, and there is no need to remove the existing wall 1, so construction is easy and construction The time is short.
In addition, the heat insulation reforming heat insulation panel 10 is composed of only the horizontal pier 11 and the heat insulating material 21, and the wall material 30 is not provided so as to cover the heat insulating material 21. Is also convenient. Moreover, since the wall material 30 is not integrated, after the heat insulation reforming heat insulation panel 10 is applied to the existing wall 1, an optimal wall material 30 can be selected and attached depending on the type of the decorative wall material. In addition, it is possible to remove or replace only the wall material 30 later by remodeling or the like. A plaster board is often used as the wall material 30, but since the plaster board is heavy and easily broken, it is generally produced and sold in a dimension shorter than the height of the wall surface. Since the heat insulating material must also be shorter than the height of the wall surface, it will be pasted on the top and bottom of the wall surface, respectively, and the construction man-hours such as installing the trunk edge will increase. Since it may be tall, construction is easy.
Moreover, since the thickness of the heat insulating material 21 is 25 millimeters (mm) or less, compared with general glass wool, thickness can be made 1/2 or less, and a room is not made extremely narrow.

In the embodiment of the present invention, as shown in FIG. 1, the heat insulation reforming heat insulation panel 10 is provided with a plurality of horizontal piers 11 and a plurality of heat insulation materials 21 having substantially the same thickness, and the uppermost and the highest heat insulation panels 21. Although the lower part is the horizontal pier 11, as shown in FIG. 3, the uppermost and lowermost parts of the heat insulating reforming insulation panel 10 are not the horizontal pier 11 but the heat insulating material 21. Good.
According to this, the adjustment in the height direction can be easily performed by cutting the uppermost heat insulating material 21 portion or the lowermost heat insulating material 21 portion.
Further, if the uppermost and lowermost portions of the heat insulating reforming heat insulation panel 10 are not the portion of the horizontal pier 11 but the heat insulating material 21, some unevenness on the ceiling and floor side where the uppermost and lowermost portions abut. Even if there is, unevenness is absorbed by the flexibility (elasticity) of the heat insulating material 21.

  In the embodiment of the present invention, as shown in FIG. 1, a plurality of heat insulating materials 21 having substantially the same thickness are used as the heat insulating reforming heat insulating panel 10, but as shown in FIG. 4, the heat insulating material 22 is used. As a single panel, the crosspiece 11 can be fitted into a groove 22a formed on the surface side (in the indoor side when the heat insulation reforming heat insulation panel 10 is applied). The interval between the grooves 22a in the vertical direction is set to a predetermined interval S as in FIG. In addition, the thickness T of the groove 22 a provided in the heat insulating material 22 and the horizontal crosspiece 11 fitted thereto is set to be smaller than ½ of the thickness W of the heat insulating material 22. Note that the thickness T of the crosspiece 11 is not limited to a wood material, as long as the head of a nail, a screw or the like can be retained, and may be made of a very thin resin or metal. . Further, the method of forming the groove 22a is not particularly limited. For example, the groove 22a is formed by shaving a single panel 10 later to form the groove 22a or when the heat insulating material 22 is manufactured. Can be formed.

According to the heat insulation reforming heat insulation panel 10 shown in FIG. 4, the entire back surface of the heat insulation reforming heat insulation panel 10 becomes the heat insulation material 22, and the region of the heat insulation material 22 is continuously provided without a break. As shown in FIG. 1, there is no place where the horizontal crosspiece 11 having a higher thermal conductivity than the heat insulating material is connected from the front surface side to the back surface side of the heat insulating reforming heat insulating panel 10, and the heat insulating performance is improved accordingly.
Moreover, since the thickness T of the groove 22a provided in the heat insulating material 22 and the horizontal crosspiece 11 fitted therein is made smaller than 1/2 of the thickness W of the heat insulating material 22, the volume (volume) of the heat insulating material is reduced. ) And the heat insulation performance is improved accordingly.
Here, while the thickness of the heat insulating material 22 is set to 15 millimeters (mm), the thickness of the crosspiece 11 is used to be 5.5 millimeters (mm). The thickness T of the horizontal pier 11 is larger than ½ of the thickness W of the heat insulating material 22, for example, the thickness of the heat insulating material 22 is set to 15 millimeters (mm). Even if a thickness of 9 millimeters (mm) is used, the heat insulation effect is improved because the heat bridge is not formed. However, the thinner the horizontal pier 11 is, the more the heat insulating effect is improved. The point is that the head of screws, nails, staples, finish nails, etc. stays at the crosspiece 11 until the wall material 30 is firmly fixed to the existing wall 1 and the heat insulating reforming heat insulating panel 10 is fixed. If there is strength of.

Further, in the heat insulation reforming heat insulation panel 10 shown in FIG. 4, the portions of the heat insulating material 22 are present at the uppermost and lowermost positions. However, as shown in FIG. 11 may be provided. That is, what is shown in FIG. 5 is that in the heat insulation reforming heat insulation panel 10 shown in FIG. 4, the uppermost horizontal pier 11 is provided at the uppermost position of the heat insulation reforming heat insulation panel 10 itself, and the lowermost horizontal pier 11 is provided. Is provided at the bottom of the heat insulation reforming heat insulation panel 10 itself, and five horizontal piers 11 are provided between the uppermost horizontal pier 11 and the lowest horizontal pier 11 so that a total of seven horizontal piers 11 are equally spaced. It is what we arranged in.
In addition, if it is made like FIG. 4, the fine adjustment of a height direction can be easily performed by cut | disconnecting the part of the heat insulating material 21 slightly.

Moreover, as shown in FIG. 6 thru | or 13, the vertical crosspiece 12 extended up and down is arrange | positioned at the right-and-left both ends of the horizontal crosspiece 11, and these vertical crosspieces 12, the horizontal crosspiece 11, and the heat insulating materials 21 and 22 are integrated. You can also.
According to this, since the vertical crosspiece 12 becomes a frame material together with the horizontal crosspiece 11, the strength of the heat insulation reforming heat insulation panel 10 can be sufficiently maintained.
The heat insulation reforming heat insulation panel 10 shown in FIG. 6 has vertical piers 12 extending vertically on both left and right sides of the one shown in FIG. 1, and the upper surfaces of these vertical piers 12 extend to the upper surface of the uppermost horizontal pier 11. Similarly, the lower surface of the vertical crosspiece 12 is provided up to the lower surface of the lowermost horizontal crosspiece 11, so that a so-called vertical winning state is obtained. Although not shown in the drawing, the uppermost horizontal pier 11 and the lowermost horizontal pier 11 protrude from the heat insulating material 21 at the left and right ends, and the vertical pier 12 is provided between the protruding upper and lower horizontal piers 11. Thus, a so-called side-winning state can be obtained.

In addition, although illustration was abbreviate | omitted, about the horizontal crosspiece 11 located in the middle except the top horizontal crosspiece 11 and the lowest horizontal crosspiece 11, it protrudes in the both right and left ends rather than the heat insulating material 21, and fits the protruded site | part. A notch may be formed at a corresponding position on the vertical crosspiece 12. With such a structure, the horizontal pier 11 and the vertical pier 12 can be firmly fixed.

  In addition, in the heat insulation reforming heat insulation panel 10 shown in FIGS. 8 to 12, as shown in FIG. 5, the horizontal crosspieces 11 are provided at the uppermost and lowermost positions so that the heat insulating material 22 does not protrude vertically. Also good.

  Moreover, like the heat insulation reforming heat insulation panel 10 shown in FIG. 13, the horizontal crosspiece 11 is fitted in the groove 22a formed in the heat insulating material 22 composed of one panel shown in FIG. The vertical piers 12 extending vertically are arranged on both left and right ends of the book), and only the uppermost horizontal pier 11 and the lowermost horizontal pier 11 have the same thickness as that of the heat insulating material 22. The upper surface may be provided up to the upper surface of the uppermost horizontal pier 11, and similarly the lower surface of the vertical pier 12 may be provided up to the lower surface of the lowermost horizontal pier 11.

Further, as shown in FIG. 14, notches 11a and 12a in which the horizontal pier 11 and the vertical pier 12 are notched are provided in the upper and lower portions of the heat insulation reforming heat insulation panel 10, and a baseboard or If there are surrounding edges or wallpaper bulges, they may be placed in the notches 11a and 12a so that they can be installed without creating a gap between the existing wall 1 or the like and the heat insulation reforming heat insulation panel 10. .
Further, as shown in FIG. 15, the groove 22 a formed in the heat insulating material 22 is a dovetail groove, and the cross-sectional shape of the horizontal pier 11 fitted into the dovetail groove is also a cross-sectional shape corresponding to the groove, and the heat insulating material You may make it insert in the horizontal crosspiece 11 with respect to 22 from the left-right direction.

Moreover, in this embodiment, although the heat insulation reform was given to the existing wall 1, even if it carries out with respect to the existing ceiling 2, for example, a fixed heat insulation effect is acquired.
Moreover, when performing the heat insulation reform which concerns on this embodiment with respect to one room of apartment houses, such as an apartment, the wall 1 which is a boundary with an adjacent room passes a dumpling-like resin mortar on a concrete body. The existing wall made of plasterboard that has been bonded and bonded is the mainstream, and the heat insulation reforming heat insulation panel 10 described in the present embodiment is applied to such a wall 1.

In this embodiment, phenol foam is used as the heat insulating material. However, it may be a board-like material that can obtain high heat insulating performance even if it is thin. Preferably, a material having an oxygen index of 26 or more and excellent flame retardancy is preferable. Depending on the installation location, it is also possible to use a heat insulating material certified by the Ministry of Land, Infrastructure, Transport and Tourism as a non-combustible material. If such a heat insulating material is used and a non-combustible material is certified as a heat insulating reforming heat insulating panel, the wall finishing material 40 such as wallpaper is directly used for the heat insulating reform without using the wall material 30 as shown in FIG. It can also be applied to a heat insulating panel. In this case, since the wall material 30 is not provided, the heat insulation reform can be performed in a thinner space. Conversely, for example, if the thickness of the insulation panel is increased to 24.5 millimeters (mm), which is the same thickness as the case where a 15 millimeter (mm) insulation panel and a 9.5 millimeter (mm) plaster board are used. Since the thickness of the heat insulating panel is 1.5 times or more, it is possible to perform reforming with a higher heat insulating effect.
Further, for example, the price is extremely high and needs to be handled with care, but it is also possible to use a vacuum heat insulating material or the like.

In consideration of various conditions as a heat insulating material capable of obtaining high heat insulating performance even if it is thin, it is preferable to use a heat insulating material having a thermal conductivity of E rank (thermal conductivity 0.028 to 0.023) or less. More preferably, if a Class A phenol foam heat insulating plate No. 1 No. 1, No. 2 or the like of F rank (thermal conductivity 0022 or less) is used as a heat insulating material, heat insulating performance can be obtained even if it is thin, and non-flammable performance is also obtained. can get. Compared to C-rank (thermal conductivity 0.040-0.035) insulation, the E-rank insulation is about 70% thick, and the F-rank insulation is about 50% or less. Equivalent thermal insulation is obtained. On the other hand, glass wool, rock wool, and the like are excellent in nonflammability, but are not preferable because they can only obtain heat insulation performance of C rank, or even D rank (thermal conductivity 0.034 to 0.029). On the other hand, heat insulating materials such as polystyrene foam and rigid urethane foam are inferior in incombustible performance, but can obtain heat insulating performance of about E rank, and can be used. However, at present, phenol foam is most preferable as a heat insulating material from the viewpoints of heat insulating performance, incombustibility, moisture absorption performance, moisture proof performance, workability, and the like.
Each rank of C, D, E, and F here is a rank in the heat insulating material classification of the incorporated administrative agency Housing Finance Support Organization.
In this embodiment, the A type phenol foam heat insulating board type 1 No. 2 whose thermal insulation classification is F rank (thermal conductivity 0.022 or less) was used as the thermal insulations 21 and 22.
