Description

[Technical Field]

[0001] The present invention relates to an interior wall panel using a heat insulating material with ears for use in the interior walls of buildings such as houses, and to an interior wall heat insulating structure using the interior wall panel. [Background technology]

[0002] Conventionally, when producing interior wall panels equipped with insulation, the insulation is fixed to an interior wall frame made of wood or iron. The fixing method involves using staples or screws to press the bulging insulation onto the frame. As a result, the periphery of the insulation fixed with screws is compressed, making it thinner than its nominal thickness. This results in a decrease in insulation performance due to the thinner insulation.

[0003] Therefore, Patent Document 1 describes an insulating material with ears that uses a bag-shaped moisture-proof film that covers the entire insulating material and ears that stretch the moisture-proof film in all four directions in the in-plane direction. In an insulating material with ears, the insulating material is inserted between a pillar and a stud adjacent to the pillar, and the ears of the moisture-proof film that extend in all four directions from the periphery of the insulating material are fixed to the pillar or stud using appropriate means such as staples or nails. Because the insulation is fixed at the ears that do not have insulating material, it does not become thinner than the nominal pressure and there is no decrease in insulating performance. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent Publication No. 2001-271437 Summary of the Invention [Problem to be solved by the invention]

[0005] However, with the fixing method described in Patent Document 1, since the insulation is not fixed near the center, it does not become thinner than the nominal pressure and therefore does not lose its insulating performance, but since the insulation, which has a relatively large surface area, is fixed to the interior wall frame at the ears of the thin film on the periphery of the insulation with "points" such as staples, this can cause the ears around the fixing points to break when the insulation with ears is pulled during work. Also, since the insulation is not installed in the areas of pillars and studs, the insulation line is broken and the insulating performance is reduced.

[0006] Therefore, in order to solve the above problems, the present invention aims to provide an interior wall panel using insulation material with edges that does not cause tears or other damage to the film at the edges, and an interior wall insulation structure using such an interior wall panel without reducing the insulation performance. [Means for solving the problem]

[0007] In order to solve the above problems, the present invention provides a method for manufacturing a heat insulating material comprising: a rectangular inner wall frame that is an inner wall base of a building; an insulating material with ears that is fixed adjacent to the inner wall frame; One side opens, The insulation material with lugs has an insulation material whose periphery is covered with a film and lugs extending in the in-plane direction of the insulation material from the periphery of the film, and the clip pieces clamp the inner wall frame and the lugs, and the insulation material with lugs is fixed to the inner wall frame. The clip piece has two clamping plate portions and a projection plate portion that connects the ends of the clamping plate portions and has a thickness equal to or shorter than the thickness of the inner wall frame. The feature of this is that

[0008] The clip has a feature that the inner surface of the clip piece has a non-slip portion.

[0009] The anti-slip portion is characterized by having a saw blade shape.

[0010] An interior wall panel as described in any one of claims 1 to 3, characterized in that the clip pieces are non-flammable, the interior wall frame includes a pair of vertical frame members on the left and right and a pair of horizontal frame members on the top and bottom, the length of the vertical clip pieces fixed to the vertical frame members is approximately the same as the length of the vertical frame members, and the length of the horizontal clip pieces fixed to the horizontal frame members is approximately the same as the length of the horizontal frame members, and the vertical clip pieces and horizontal clip pieces are connected.

[0011] This is an interior wall insulation structure using the interior wall panels described in the above characteristics, characterized in that the interior wall panels are arranged continuously, and joint insulation material is arranged on the outdoor side of the clip piece to fill the vertical joints that occur between the ear insulation materials of adjacent interior wall panels, and the ear insulation material and joint insulation material are arranged alternately and continuously in the horizontal direction. [Effects of the Invention]

[0012] The interior wall panel of the present invention uses elastic, U-shaped clip pieces that clamp the lug of the insulation material to the interior wall frame, securing the insulation material to the interior wall frame. This secures the lug with a wire, preventing tearing of the lug. It can also be easily removed and reattached.

[0013] Furthermore, by providing an anti-slip portion on the inner surface of the clip piece, the clip piece will not come off and fall off the inner wall frame.

[0014] Furthermore, since the anti-slip portion has a sawtooth shape, the sawtooth bites into the film and the inner wall frame, preventing the clip piece from slipping off the inner wall frame.

[0015] In addition, the clip pieces are non-flammable, and the inner wall frame is formed from a pair of vertical frame members on the left and right and a pair of horizontal frame members on the top and bottom, and the length of the vertical clip pieces fixed to the vertical frame members is approximately the same as the length of the vertical frame members, and the length of the horizontal clip pieces fixed to the horizontal frame members is approximately the same as the length of the horizontal frame members, and since the vertical clip pieces and horizontal clip pieces are connected, even if the inner wall frame catches fire, the inner wall will not collapse, and the clip pieces will stand on their own as the inner wall frame and will not collapse.

[0016] In addition, the interior wall panels are arranged continuously along the framework that supports the building, and joint insulation is arranged to fill the vertical joints that occur between the insulation with ears of adjacent interior wall panels and the gap between the framework and the outdoor side of the clip piece, and the insulation with ears and joint insulation are arranged alternately and continuously in the horizontal direction, preventing the formation of thermal bridges and preventing heat from escaping from indoors to outdoors, thereby improving insulation performance and preventing condensation.

DETAILED DESCRIPTION OF THE INVENTION

[0018] The interior wall panels 100, 200 according to the present invention are used on the interior walls of buildings and are building materials with thermal insulation properties. As shown in FIG. 1, the interior wall panels 100, 200 mainly include a rectangular interior wall frame 1, an insulating material with lugs 2 arranged on the interior wall frame 1, and an elastic, U-shaped clip piece 3. In this specification, the back surface of the insulating material with lugs 2 or the interior wall frame 1 refers to the surface facing the outdoors when the interior wall panel 100, 200 is installed on an interior wall, and the front surface of the insulating material with lugs 2 or the interior wall frame 1 refers to the surface facing the indoor side when the interior wall panel 100, 200 is installed on an interior wall. As shown in FIG. 2, the insulating material with lugs 2 is arranged so as to protrude from the outdoors side, which is the back surface of the interior wall frame 1.

[0019] [First embodiment] The interior wall panel 100 is assembled on-site by placing the heat insulating material 2 with ears on the interior wall frame 1 and then attaching the grip pieces 3. After the interior wall panel 100 is assembled, it is attached to the framework C of the building, as shown in Figure 2.

[0020] (Regarding inner wall frame 1) The interior wall frame 1 is used as the interior wall base of a building. The interior wall frame 1 is mainly made of wood, and is made up of a pair of left and right vertical frame members 1a and a pair of top and bottom horizontal frame members 1b, which are fastened together to form a rectangular shape using well-known fastening means such as nails or adhesives.

[0021] (About insulation with ears 2) The heat insulating material 2 with tabs comprises a heat insulating material 2b whose periphery is covered with a film 2a, and tabs 2c extending in the in-plane direction of the heat insulating material 2b from the peripheral edge of the bottom surface of the film 2a. As shown in Figures 1(a) and 1(b), the clip pieces 3 clamp the inner wall frame 1 and the tabs 2c, and the tabs 2c are fixed to the inner wall frame 1, thereby fixing the heat insulating material 2 with tabs onto the inner wall frame 1.

[0022] The insulating material 2b is a fibrous material, such as glass wool or rock wool, that can be easily deformed by pressure. The insulating material 2b is pre-cut to an appropriate size to fit the interior wall frame 1 and packed into a bag-shaped film 2a for moisture protection, ease of processing, and to prevent the processed fibers from unraveling. The size of the insulating material 2b is approximately the same as the size inside the interior wall frame 1, so that it fits between a pair of vertical frame members 1a on the left and right. Its thickness is preferably greater than that of the interior wall frame 1, and it bulges out toward the back side of the interior wall frame 1, i.e., the exterior. The insulating material 2b is surrounded by a bag-shaped film 2a, which is moisture-proof and has a thickness that satisfies a certain degree of tear strength. Polyethylene is preferably used as the material. Covering the insulating material 2b with the film 2a prevents moisture from entering the wall and penetrating the interior of the insulation, preventing internal condensation and mold growth.

[0023] In this embodiment, the ear portions 2c extend from the peripheral edge of the bag-shaped film 2a in an in-plane direction outside the insulation material 2b, but they do not have to extend in all four directions in the in-plane direction; if the purpose is only to fix the insulation material with ears 2 to the inner wall frame 1, they may extend only in the left-right direction to fix it to the left and right vertical frame materials 1a.

[0024] (About clip piece 3) The clip piece 3 is U-shaped, made of metal, synthetic resin, or the like, and has elasticity. The clip piece 3 has two parallel sandwiching plate portions 3a and a recessed plate portion 3b that connects the ends of the two sandwiching plate portions 3a. The sandwiching plate portion 3a has an inner wall frame pressing plate portion 3a1 that presses the indoor side of the inner wall frame 1, and an ear pressing plate portion 3a2 that presses the outdoor side of the ear portion 2c.

[0025] The length of the projection plate portion 3b is formed to be the same as or slightly shorter than the length of the side surface of the inner wall frame 1. Therefore, by spreading the clamping plate portion 3a and inserting the ear portion 2c and the inner wall frame 1, the clamping plate portion 3a exerts an elastic force to clamp the ear portion 2c and the inner wall frame 1, and the ear-equipped insulation material 2 can be fixed to the inner wall frame 1.

[0026] As shown in Figure 3(a) or Figure 4(a), a plurality of clip pieces 3, each with a projection board portion 3b length of about 0.1 m to 1 m, are used for one vertical frame member 1a or horizontal frame member 1b. As long as the clip pieces 3 secure the ear portions 2c to the pair of left and right vertical frame members 1a, the ear portions 2c may or may not be secured to the pair of upper and lower horizontal frame members 1b.

[0027] As shown in Figures 4(b) to 6, an anti-slip portion 4 is provided on the inner surface of the clip piece 3. The anti-slip portion 4 shown in Figure 4(b) is a mountain-shaped saw blade 4a. By providing the mountain-shaped saw blade 4a at the tip of the clamping plate portion 3a, the saw blade 4a penetrates the ear portion 2c and bites into the interior wall frame 1, preventing the clip piece 3 from falling off the interior wall frame 1 during installation of the interior wall panel 100.

[0028] Furthermore, the saw blade 4a on the edge other than the tip of the ear pressing plate 3a2 has one oblique side of the mountain shape formed long, which functions as a barb, making it even more difficult for the clip piece 3 to fall off. The saw blade 4a does not have to be provided only at the tip of the clamping plate 3a, but may be provided on the periphery of the clamping plate 3a, or may be provided on the entire surface of the clamping plate 3a. Furthermore, the saw blade 4a does not have to be mountain-shaped, but may also be trapezoidal, and the shape of the saw blade 4a is not limited as long as the clip piece 3 does not fall off.

[0029] 5(a), a seam fold 4b may be provided at the end of the ear pressing plate portion 3a2 of the clip piece 3 as an anti-slip portion 4. The seam fold 4b hooks onto the ear 2c and functions as a barb, digging into the ear 2c and the inner wall frame 1 and preventing the clip piece 3 from slipping off. The seam fold 4b may be provided in multiple locations, or one may be provided along the entire end.

[0030] Alternatively, as shown in Figure 5(b), the anti-slip portion 4 may be formed by providing protruding claw portions 4c on the inside of the clip piece 3 from the surface of the ear pressing plate portion 3a2 of the clip piece 3 so as to hook the ear 2c. The protruding claw portions 4c function as a barb, digging into the ear 2c and the inner wall frame 1 and preventing the clip piece 3 from slipping off. The protruding claw portions 4c are provided at regular intervals on the ear pressing plate portion 3a2.

[0031] In addition, as shown in Figure 6(a), after fixing the ear-equipped insulation material 2 and the inner wall frame 1 to the clip piece 3, the clip piece 3 is pressed in a point-like manner from above the ear pressing plate portion 3a2, and the pressed point portion 4d presses the ear portion 2c against the inner wall frame 1, preventing the clip piece 3 from falling off.

[0032] 6(b), the frictional force may be increased by providing a sheet 4e, such as a rubber sheet or a textured sheet, on the inner surface of the edge pressing plate 3a2 as the anti-slip portion 4. Alternatively, the inner surface of the edge pressing plate 3a2 may be roughened by providing small protrusions or the like without providing the sheet 4e.

[0033] As shown in Figures 4(b) to 6, the anti-slip portion 4 is provided on the inner surface of the ear portion pressing plate portion 3a2, but if necessary, it may also be provided on the inner surface of the inner wall frame pressing plate portion 3a2 or the projection plate portion 3b at the same time.As long as the anti-slip portion 4 is provided on the inner surface of the ear portion pressing plate portion 3a2, the location of other anti-slip portions 4 is not particularly limited.

[0034] The interior wall panel 100 is not fixed to the interior wall frame 1 from above the insulation 2b, but is fixed to the interior wall frame 1 at the ears 2c where there is no insulation, so it does not become thinner than the nominal thickness. By fixing the ears 2c to the interior wall frame 1 using clip pieces 3 of a certain length, it is possible to fix the interior wall frame 1 without penetrating the ears 2c, and because it is fixed at a "line" rather than a "point," even if the insulation with ears 2 is pulled or moved, the force is not concentrated at one point, which has the effect of making the ears 2c less likely to tear.

[0035] Furthermore, if the heat insulating material with ears 2 is fixed to the inner wall frame 1 in the wrong place with staples or if the film 2a is torn, it takes time to remove the staples and the ears 2c are unnecessarily damaged. However, if the clip pieces 3 are used, they are easier to remove than staples and do not take time to remove, and since no holes are made in the ears 2c, they can be fixed again without being damaged.

[0036] 3(b), multiple horizontal crosspieces 5 may be used at a fixed pitch to connect a pair of left and right vertical frame members 1a. The provision of the horizontal crosspieces 5 supports the left and right vertical frame members 1a, providing resistance to external forces and loads such as earthquakes, preventing deformation and distortion of the non-combustible interior wall frame 7 and further increasing stability and strength. In this embodiment, the horizontal crosspieces 5 are provided on the vertical frame members 1a at positions that connect with the clip pieces 3, and are fixed to the clip pieces 3 by welding or the like.

[0037] [Regarding the second embodiment] (Regarding interior wall panel 200) The interior wall panel 200 of the second embodiment, like the interior wall panel 100, has an interior wall frame 1, an insulating material 2 with ears, and a vertically elongated clip piece 3c, which is a long clip piece 3, and a horizontally elongated clip piece 3d.

[0038] (Regarding the vertical clip piece 3c and horizontal clip piece 3d) As shown in Figures 7 and 8(a), the vertical clip pieces 3c secure the vertical frame member 1a to the left-right extending ears 2c and are formed to be approximately the same length as the vertical frame member 1a. The horizontal clip pieces 3d secure the horizontal frame member 1b to the up-down extending ears 2c and are formed to be approximately the same length as the horizontal frame member 1b. The vertical clip pieces 3c and the horizontal clip pieces 3d are made of a non-flammable material such as metal or alloy, and after being attached to the vertical frame member 1a and the horizontal frame member 1b, the vertical clip pieces 3c and the horizontal clip pieces 3d are connected by welding or the like to form the non-flammable interior wall frame 7.

[0039] The non-combustible inner wall frame 7 does not burn even if a fire breaks out and the vertical frame material 1a or the horizontal frame material 1b burns, so the non-combustible inner wall frame 7 stands on its own and the inner wall does not collapse, thereby increasing the durability of the building.

[0040] 8(b), a pair of left and right vertical clip pieces 3c may be provided with multiple horizontal bars 5 at regular intervals to connect the vertical clip pieces 3c. The horizontal bars 5 are made of a non-combustible material such as metal and are connected to the vertical clip pieces 3c by welding or the like. The horizontal bars 5 support the vertical clip pieces 3c and the left and right vertical frame members 1a.

[0041] By providing the cross bars 5, the vertical frame material 1a and the horizontal frame material 1b can be resistant to external forces after burning in the event of a fire, loads from earthquakes, etc., thereby preventing deformation and distortion of the non-flammable inner wall frame 7 and further increasing stability and strength.

[0042] In addition, the vertical clip pieces 3c and the horizontal clip pieces 3d may also be provided with anti-slip portions 4 on the inside, such as saw blades 4a, grooved portions 4b, claw portions 4c, dot portions 4d, and sheets 4e, similar to the clip pieces 3 of the interior wall panel 100 of the first embodiment.

[0043] [About the Inner Wall Insulation Structure 300] An interior wall insulation structure 300 using an interior wall panel 100 will be described with reference to Fig. 2. The interior wall insulation structure 300 mainly comprises, from the indoor side, wallpaper or other wallpaper K, gypsum board IP, the interior wall panel 100, joint insulation material 6, and a framework C. An exterior wall panel OP is provided on the outdoor side of the framework C.

[0044] A plurality of interior wall panels 100 are arranged in succession along the framework C that supports the building. Vertical joints are formed between the lug insulation 2 of adjacent interior wall panels 100. In the gap between this vertical joint and the framework C and the outdoor surface of the clip piece 3, joint insulation 6 is arranged, and the lug insulation 2 and joint insulation 6 are arranged alternately in the horizontal direction. By arranging them alternately in succession, the horizontal insulation line is formed without interruption.

[0045] By inserting the joint insulation material 6 and forming a continuous horizontal insulation line, thermal bridges can be eliminated. By eliminating thermal bridges, heat conduction from the vertical frame material 1a to the framework C is suppressed, and the insulation performance from indoors to outdoors is not reduced. It also helps prevent condensation inside the interior walls.

[0046] Adjacent frame members C have fixing brackets S arranged in a row in the vertical direction of the contacting portion. It is preferable to have at least two fixing brackets S, but the number of fixing brackets S to be installed can be set taking into consideration the strength of the interior wall frame 1, and is not limited to four. Also, for the sake of convenience of explanation, Figure 2 shows fixing brackets S attached to only one frame member C, but in reality fixing brackets S are attached to all frame members C that provide the insulated interior wall frame 1.

[0047] As shown in Figure 2, the clip pieces 3 are provided on the inner wall frame 1 so that the projection plate portions 3b of the clip pieces 3 face each other. Because the projection plate portions 3b are abutted against each other, the clip pieces 3 will not fall off, and the heat insulating material with tabs 2 can be stably fixed to the inner wall frame 1.

[0048] It is also possible to create an interior wall insulation structure 300 using the interior wall panel 200 of the second embodiment, and when the interior wall panel 200 is used, since it is a non-flammable interior wall frame 7, there is no need to separately install a non-flammable interior wall frame on the indoor side of the interior wall frame 1, and the room space does not become smaller.

[0049] (First feature) The interior wall panel comprises a rectangular interior wall frame that is the interior wall base of a building, an insulating material with ears fixed adjacent to the interior wall frame, and an elastic U-shaped clip piece, wherein the insulating material with ears is an insulating material whose periphery is covered with a film and has ears extending from the periphery of the film in the in-plane direction of the insulating material, and the clip piece clamps the interior wall frame and the ears, and the insulating material with ears is fixed to the interior wall frame.

[0050] According to the above features, the elastic U-shaped clip piece clamps the lug of the insulation material and the inner wall frame to secure the insulation material to the inner wall frame, so the lug is secured by a wire, preventing the lug from tearing. It is also easy to remove and re-attach.

[0051] (Second feature) The interior wall panel according to the first feature is characterized in that the clip piece has an anti-slip portion on the inner surface thereof.

[0052] According to the above feature, the clip piece has an anti-slip portion on the inner surface thereof, so that the clip piece does not come off and fall off the inner wall frame.

[0053] (Third feature) The interior wall panel according to the first feature is characterized in that the anti-slip portion has a sawtooth shape.

[0054] According to the above feature, since the anti-slip portion has a sawtooth shape, the sawtooth bites into the film and the inner wall frame, and the clip piece does not come off and fall off the inner wall frame.

[0055] (Fourth feature) The clip pieces are non-flammable, the interior wall frame includes a pair of vertical frame members on the left and right and a pair of horizontal frame members on the top and bottom, the length of the vertical clip pieces fixed to the vertical frame members is approximately the same as the length of the vertical frame members, the length of the horizontal clip pieces fixed to the horizontal frame members is approximately the same as the length of the horizontal frame members, and the vertical clip pieces and the horizontal clip pieces are connected to each other, which is an interior wall panel described in any one of the first to third features.

[0056] According to the above features, the clip pieces are non-flammable, and the inner wall frame is formed from a pair of vertical frame members on the left and right and a pair of horizontal frame members on the top and bottom, and the length of the vertical clip pieces fixed to the vertical frame members is approximately the same as the length of the vertical frame members, and the length of the horizontal clip pieces fixed to the horizontal frame members is approximately the same as the length of the horizontal frame members, and since the vertical clip pieces and horizontal clip pieces are connected, even if the inner wall frame catches fire, the inner wall will not collapse, and the clip pieces will be able to stand on their own as the inner wall frame and will not collapse.

[0057] (5th feature) The present invention provides an interior wall insulation structure using an interior wall panel described in any one of the first to fourth features, characterized in that the interior wall panels are arranged continuously, and joint insulation material is arranged on the outdoor side of the clip piece to fill the vertical joints that occur between the ear insulation material of adjacent interior wall panels, and the ear insulation material and the joint insulation material are arranged alternately and continuously in the horizontal direction.
