Description

Technical Field

[0001] The present invention relates to an inner wall panel using a heat insulating material with ears for an inner wall of a building such as a house, and an inner wall heat insulating structure using the inner wall panel.

Background Art

[0002] Conventionally, when producing an inner wall panel provided with a heat insulating material, the heat insulating material was fixed to an inner wall frame formed of wood or iron. As the fixing method, staples, screws, etc. were pressed from above the bulging heat insulating material to fix it to the inner wall frame. Therefore, the peripheral portions of the heat insulating material fixed by screws etc. were compressed and became thinner than the nominal thickness. Thus, the heat insulating performance decreased by the amount that the heat insulating material became thinner.

[0003] Therefore, in Patent Document 1, a heat insulating material with ears is described, which uses a bag-shaped moisture-proof film that entirely covers the heat insulating material, and ears where the moisture-proof film is stretched out in all directions in the in-plane direction. The heat insulating material with ears inserts the heat insulating material between a column and an intermediate column adjacent to the column, and the ears of the moisture-proof film extending in all directions from the peripheral edge of the heat insulating material are fixed to the column or the intermediate column using appropriate means such as staples or nails. Since the fixing is performed on the ears without the heat insulating material, it does not become thinner than the nominal pressure, and the heat insulating performance does not decrease.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in the fixing method described in Patent Document 1, since the fixing is not performed near the center of the heat insulating material, it does not become thinner than the nominal pressure and the heat insulating performance does not decrease. However, for a heat insulating material with a relatively large area, it is fixed to the inner wall frame at "points" such as staples at the ears of the thin film at the periphery of the heat insulating material. Therefore, during work, the ear of the heat insulating material with ears is pulled, etc., which causes the ear around the fixing point to be torn. In addition, since the heat insulating material is not provided at the location of the column or the intermediate column, the heat insulating line is interrupted and the heat insulating performance is reduced.

[0006] Therefore, in order to solve the above problems, the present invention provides an inner wall panel using a heat insulating material with ears that does not cause tearing or the like in the film of the ears, and an inner wall heat insulating structure using the inner wall panel without reducing the heat insulating performance.

Means for Solving the Problems

[0007] In order to solve the above problems, it has a rectangular inner wall frame that is the inner wall base of a building, a heat insulating material with ears fixed adjacent to the inner wall frame, and an elastic U-shaped clip piece. The heat insulating material with ears includes a heat insulating material whose periphery is covered with a film, and ears extending from the periphery of the film in the in-plane direction of the heat insulating material. The clip piece sandwiches the inner wall frame and the ears, and the heat insulating material with ears is fixed to the inner wall frame.

[0008] It is characterized in that the inner surface of the clip piece has an anti-slip portion.

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

[0010] The clip piece is incombustible. The inner wall frame includes a pair of vertical frame members that are a left-right pair and a pair of horizontal frame members that are an upper-lower pair. Among the clip pieces, the length of the vertically long clip piece fixed to the vertical frame member is substantially the same as the length of the vertical frame member. Among the clip pieces, the length of the horizontally long clip piece fixed to the horizontal frame member is substantially the same as the length of the horizontal frame member. The inner wall panel according to any one of claims 1 to 3, characterized in that the vertically long clip piece and the horizontally long clip piece are connected.

[0011] An inner wall heat insulation structure using the inner wall panel described in the above characteristics, wherein the inner wall panels are arranged continuously, and a joint heat insulation material is arranged on the outdoor side of the clip piece to fill a vertical joint generated between the heat insulation materials with ears of adjacent inner wall panels, and the heat insulation materials with ears and the joint heat insulation material are arranged alternately and continuously in the horizontal direction.

Effect of the Invention

[0012] According to the inner wall panel of the present invention, the U-shaped clip piece having elasticity sandwiches the ear part of the heat insulation material with ears and the inner wall frame, and fixes the heat insulation material with ears to the inner wall frame, so that it is fixed with a wire and the ear part will not be torn. Also, it is easy to remove and fix again.

[0013] Moreover, by having an anti-slip part on the inner surface of the clip piece, the clip piece will not fall off from the inner wall frame.

[0014] Moreover, since the anti-slip part is in the shape of a saw blade, the saw blade bites into the film and the inner wall frame, and the clip piece will not fall off from the inner wall frame.

[0015] Moreover, the clip piece is incombustible, and an inner wall frame formed by a pair of vertical frame members that are a left-right pair and a pair of horizontal frame members that are an up-down pair. Among the clip pieces, the length of the vertically long clip piece fixed to the vertical frame member is substantially the same as the length of the vertical frame member, and among the clip pieces, the length of the horizontally long clip piece fixed to the horizontal frame member is substantially the same as the length of the horizontal frame member. Since the vertical clip piece and the horizontal clip piece are connected, even when the inner wall frame burns, the inner wall will not collapse, and the clip piece can be made to stand on its own as an inner wall frame and not collapse.

[0016] In addition, inner wall panels are continuously arranged along the framework that supports the building, and a joint heat insulating material that fills the gap between the framework and the outdoor side surface of the clip piece is arranged at the vertical joint that occurs between the heat insulating materials with ears of adjacent inner wall panels. By arranging the heat insulating materials with ears and the joint heat insulating materials alternately and continuously in the horizontal direction, it is possible to prevent the formation of thermal bridges, improve the heat insulation performance by preventing heat from escaping from the indoor to the outdoor, and prevent condensation.

Best Mode for Carrying Out the Invention

[0018] The inner wall panels 100 and 200 according to the present invention are building materials used for the inner walls of buildings and have heat insulation performance. As shown in FIG. 1, the inner wall panels 100 and 200 mainly include a rectangular inner wall frame 1, a heat insulating material 2 with ears disposed on the inner wall frame 1, and an elastic U-shaped clip piece 3. In this specification, the back surface of the heat insulating material 2 with ears or the inner wall frame 1 refers to the surface on the outdoor side when the inner wall panel 100 or 200 is installed on the inner wall portion, and the front surface of the heat insulating material 2 with ears or the inner wall frame 1 refers to the surface on the indoor side when the inner wall panel 100 or 200 is installed on the inner wall portion. As shown in FIG. 2, the heat insulating material 2 with ears is disposed so as to protrude on the outdoor side which is the back surface of the inner wall frame 1.

[0019] [First Embodiment] The inner wall panel 100 is assembled on site by mounting the heat insulating material 2 with ears on the inner wall frame 1 and then attaching the grip piece 3. As shown in FIG. 2, after the inner wall panel 100 is assembled, the inner wall panel 100 is attached to the building axis C.

[0020] (Regarding the inner wall frame 1) The inner wall frame 1 is used as the inner wall base of the building. The inner wall frame 1 is mainly made of wood, and a pair of left and right vertical frame members 1a and a pair of upper and lower horizontal frame members 1b are respectively fixed by well-known fixing means such as nails and adhesives so as to form a rectangular frame.

[0021] (Regarding the heat insulating material 2 with ears) The heat insulating material 2 with ears includes a heat insulating material 2b covered with a film 2a around it, and an ear portion 2c extending from the periphery of the bottom surface of the film 2a in the in-plane direction of the heat insulating material 2b. As shown in FIGS. 1(a) and 1(b), the clip piece 3 sandwiches the inner wall frame 1 and the ear portion 2c, and the ear portion 2c is fixed to the inner wall frame 1, so that the heat insulating material 2 with ears is fixed on the inner wall frame 1.

[0022] The heat insulating material 2b is fibrous such as glass wool or rock wool, and can be easily deformed by being pressed. The heat insulating material 2b is pre-cut to an appropriate size according to the size of the inner wall frame 1, and is packed in a bag-shaped film 2a for moisture prevention, easy processing, and preventing the processed fibers from unraveling. The size of the heat insulating material 2b is substantially the same as the size inside the inner wall frame 1 and is such that it can be accommodated between a pair of left and right vertical frame members 1a. The thickness is preferably larger than the thickness of the inner wall frame 1, and it bulges out on the back side of the inner wall frame 1, that is, the outdoor side. The heat insulating material 2b is covered by a bag-shaped film 2a around it, has moisture-proof property, and is set to a thickness that satisfies a certain degree of tear strength. The material is preferably made of polyethylene. By covering the heat insulating material 2b with the film 2a, it suppresses moisture from entering the wall body and penetrating into the inside of the heat insulation, preventing the occurrence of internal condensation and preventing the growth of mold.

[0023] In this embodiment, the ear part 2c extends from the periphery of the bag-shaped film 2a in the in-plane direction of the outer surface of the heat insulating material 2b. However, as long as it is only for fixing the heat insulating material 2 with ears to the inner wall frame 1, even if it does not extend in all four directions in the in-plane direction, it may extend only in the left-right direction in order to be fixed to the left and right vertical frame members 1a.

[0024] (Regarding the clip piece 3) The clip piece 3 is U-shaped, made of metal, synthetic resin, etc., and has elasticity. The clip piece 3 has a clamping plate part 3a which is two parallel plates, and a prospective plate part 3b which connects the ends of the two clamping plate parts 3a. The clamping plate part 3a has an inner wall frame pressing plate part 3a1 which presses the indoor side of the inner wall frame 1 and an ear pressing plate part 3a2 which presses the outdoor side of the ear part 2c.

[0025] The length of the prospective plate part 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 part 3a and inserting the ear part 2c and the inner wall frame 1, an elastic force acts on the clamping plate part 3a to sandwich the ear part 2c and the inner wall frame 1, and the heat insulating material 2 with ears can be fixed to the inner wall frame 1.

[0026] As shown in Fig. 3(a) or Fig. 4(a), a plurality of clip pieces 3 with the length of the prospective plate portion 3b being about 0.1 m to 1 m are used for one vertical frame member 1a or horizontal frame member 1b. If the ear portion 2c is fixed to a pair of left and right vertical frame members 1a by the clip pieces 3, the ear portion 2c may or may not be fixed to a pair of upper and lower horizontal frame members 1b.

[0027] As shown in Figs. 4(b) to 6, an anti-slip portion 4 is provided on the inner surface of the clip piece 3. As the anti-slip portion 4, the one shown in Fig. 4(b) is a saw blade 4a in a mountain shape. By providing the shape of the saw blade 4a in a mountain shape at the tip of the clamping plate portion 3a, the saw blade 4a penetrates the ear portion 2c and bites into the inner wall frame 1, and the clip piece 3 is formed so as not to fall off from the inner wall frame 1 during the construction of the inner wall panel 100.

[0028] Also, the saw blade 4a at the edge that is not the tip of the ear pressing plate portion 3a2 of the clip piece 3 functions as a return by forming one of the hypotenuses of the mountain shape longer, and the clip piece 3 has a shape that is more difficult to fall off. The saw blade 4a may be provided not only at the tip of the clamping plate portion 3a but also on the peripheral edge of the clamping plate portion 3a or on the entire surface of the clamping plate portion 3a. Further, the saw blade 4a may not only be in a mountain shape but also in a trapezoidal shape, and the shape of the saw blade 4a is not limited as long as the clip piece 3 does not fall off.

[0029] Also, as shown in Fig. 5(a), as the anti-slip portion 4, a crack folding portion 4b may be provided at the end of the ear pressing plate portion 3a2 of the clip piece 3. The crack folding portion 4b catches the ear portion 2c and functions as a return, thereby biting into the ear portion 2c and the inner wall frame 1 and preventing the clip piece 3 from falling off. The crack folding portion 4b may be provided at a plurality of locations or one may be provided for the entire end portion.

[0030] Also, as shown in Fig. 5(b), as the anti-slip portion 4, a claw projecting portion 4c may be provided from the surface of the ear pressing plate portion 3a2 of the clip piece 3 to the inside of the clip piece 3 so as to hook the ear portion 2c. By the claw projecting portion 4c functioning as a catch, it bites into the ear portion 2c and the inner wall frame 1, preventing the clip piece 3 from falling off. The claw projecting portions 4c are provided at regular intervals on the ear pressing plate portion 3a2.

[0031] Also, as shown in Fig. 6(a), as the anti-slip portion 4, after fixing the ear-attached heat insulating material 2 and the inner wall frame 1 to the clip piece 3, by pressing dot-like from above the ear pressing plate portion 3a2, 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] Also, as shown in Fig. 6(b), as the anti-slip portion 4, for example, a sheet 4e having a large frictional force against the ear portion 2c, such as a rubber sheet or a sheet with an uneven shape, may be provided on the inner side surface of the ear pressing plate portion 3a2 to increase the frictional force. Also, even if the sheet 4e is not provided, the inner side surface of the ear pressing plate portion 3a2 may be roughened by providing small protrusions or the like.

[0033] As shown in Figs. 4(b) to 6, the anti-slip portion 4 is provided on the inner side surface of the ear pressing plate portion 3a2. However, if necessary, it may also be provided simultaneously on the inner side surfaces of the inner wall frame pressing plate portion 3a2 and the prospective plate portion 3b. If the anti-slip portion 4 is provided on the inner side surface of the ear pressing plate portion 3a2, the location of the other anti-slip portions 4 is not particularly limited.

[0034] The inner wall panel 100 is not fixed to the inner wall frame 1 from above the heat insulating material 2b, but is fixed to the inner wall frame 1 at the ear portion 2c without the heat insulating material. Therefore, it does not become thinner than the nominal thickness. And by using a clip piece 3 having a certain length to fix the ear portion 2c to the inner wall frame 1, the ear portion 2c can be fixed to the inner wall frame 1 without passing through it, and since it is fixed by a "line" rather than a "point", even when the ear-attached heat insulating material 2 is pulled or moved, the force does not concentrate at a single point, so there is an effect that the ear portion 2c is less likely to be torn.

[0035] Also, even if the location where the heat insulating material 2 with ears is fixed to the inner wall frame 1 is mistaken and fixed with staples, or the film 2a is torn, etc., it takes time to remove the staples and the ear part 2c will be damaged uselessly. However, when using the clip piece 3, it is easier to remove compared to staples etc., does not take much time, and since no holes are formed in the ear part 2c, it can be fixed again without being damaged.

[0036] Also, if necessary, as shown in Fig. 3(b), a plurality of horizontal bars 5 connecting the pair of left and right vertical frame members 1a may be used at regular pitch intervals. By providing the horizontal bars 5, the left and right vertical frame members 1a are supported, and it is possible to have resistance against external forces and loads such as earthquakes, prevent deformation and distortion of the non-combustible inner wall frame 7, and further increase stability and strength. In the present embodiment, the horizontal bar 5 is provided at a position where it is connected to the clip piece 3 in the vertical frame member 1a and is fixed to the clip piece 3 by welding or the like.

[0037] [Regarding the Second Embodiment] (Regarding the inner wall panel 200) The inner wall panel 200 according to the second embodiment has, similarly to the inner wall panel 100, an inner wall frame 1, a heat insulating material 2 with ears, a vertically long clip piece 3c in which the clip piece 3 is long, and a horizontally long clip piece 3d.

[0038] (Regarding the vertically long clip piece 3c and the horizontally long clip piece 3d) As shown in Figs. 7 and 8(a), the vertically long clip piece 3c is for fixing the vertical frame member 1a and the ear part 2c extending left and right, and is formed to have approximately the same length as the vertical frame member 1a. The horizontally long clip piece 3d is for fixing the horizontal frame member 1b and the ear part 2c extending up and down, and is formed to have approximately the same length as the horizontal frame member 1b. The vertically long clip piece 3c and the horizontally long clip piece 3d are formed of a non-combustible material such as metal or alloy, and the vertically long clip piece 3c and the horizontally long clip piece 3d are connected by welding or the like after being attached to the vertical frame member 1a and the horizontal frame member 1b to form the non-combustible inner wall frame 7.

[0039] Even when a fire breaks out and the vertical frame members 1a and the horizontal frame members 1b burn, the non-combustible inner wall frame 7 will not burn. By being self-supporting, the inner wall will not collapse, and the durability of the building can be improved.

[0040] Also, as shown in FIG. 8(b), a plurality of horizontal crossbars 5 connecting the vertically long clip pieces 3c may be provided at regular pitches between the pair of vertically long clip pieces 3c on the left and right. The horizontal crossbars 5 are formed of a non-combustible material such as metal and are connected to the vertically long clip pieces 3c by welding or the like. By providing the horizontal crossbars 5, the vertically long clip pieces 3c and the left and right vertical frame members 1a are supported.

[0041] By providing the horizontal crossbars 5, it is possible to have resistance against external forces and loads such as earthquakes after the vertical frame members 1a and the horizontal frame members 1b burn during a fire, prevent deformation and distortion of the non-combustible inner wall frame 7, and further improve stability and strength.

[0042] Also, the vertically long clip pieces 3c and the horizontally long clip pieces 3d may also be provided with anti-slip portions 4 such as a saw blade 4a, a beveled portion 4b, a claw projecting portion 4c, a dot portion 4d, and a sheet 4e on the inside, similar to the clip pieces 3 of the inner wall panel 100 according to the first embodiment.

[0043] [Regarding the inner wall heat insulation structure 300] The inner wall heat insulation structure 300 using the inner wall panel 100 will be described with reference to FIG. 2. The inner wall heat insulation structure 300 mainly includes, in order from the indoor side, a cloth K such as wallpaper, a gypsum board IP, an inner wall panel 100, a joint heat insulating material 6, and a framework C. An outer wall panel OP is provided on the outdoor side of the framework C.

[0044] A plurality of inner wall panels 100 are continuously arranged along the frame C that supports the building. A vertical joint is formed between the heat insulating materials 2 with ears of adjacent inner wall panels 100. At this vertical joint, a joint heat insulating material 6 is arranged in the gap between the frame C and the outdoor side surface of the clip piece 3, and the heat insulating materials 2 with ears and the joint heat insulating material 6 are continuously arranged alternately in the horizontal direction. By arranging them continuously and alternately, a horizontal heat insulating material line is formed so as not to be interrupted.

[0045] By interposing the joint heat insulating material 6 to form a horizontal heat insulating material line so as not to be interrupted, heat bridges can be eliminated. By eliminating heat bridges, heat conduction from the vertical frame member 1a to the frame C is suppressed, and the heat insulation performance from the indoor to the outdoor does not decrease. Also, condensation prevention can be achieved inside the inner wall.

[0046] Fixing brackets S are arranged in a row in the vertical direction of the contacting portions between adjacent frames C. It is preferable that there are at least two or more fixing brackets S, but the number of fixing brackets S to be provided should be set considering the strength of the inner wall frame 1 etc., and it is not limited to four. Also, in FIG. 2, for convenience of explanation, only one frame C with a fixing bracket S attached is shown, but actually, fixing brackets S are attached to all frames C where the heat insulating inner wall frame 1 is provided.

[0047] As shown in FIG. 2, the clip piece 3 is provided on the inner wall frame 1 such that the prospective plate portions 3b of the clip piece 3 face each other. Since the prospective plate portions 3b are butted against each other, the clip piece 3 cannot fall off, and the heat insulating material 2 with ears can be stably fixed to the inner wall frame 1.

[0048] Also, it is possible to use an inner wall heat insulation structure 300 using the inner wall panel 200 according to the second embodiment. When using the inner wall panel 200, since it is a non-combustible inner wall frame 7, there is no need to separately provide a non-combustible inner wall frame on the indoor side of the inner wall frame 1, and the room space does not become smaller.

[0049] (The first feature) It has a rectangular inner wall frame which is the base of the inner wall of the building, a heat-insulating material with ears fixed adjacent to the inner wall frame, and an elastic U-shaped clip piece. The heat-insulating material with ears includes a heat-insulating material covered with a film around it and ears extending in the in-plane direction of the heat-insulating material from the peripheral edge of the film. The clip piece sandwiches the inner wall frame and the ears, and the heat-insulating material with ears is fixed to the inner wall frame, which is the characteristic of the inner wall panel.

[0050] According to the above characteristics, since the elastic U-shaped clip piece sandwiches the ears of the heat-insulating material with ears and the inner wall frame to fix the heat-insulating material with ears to the inner wall frame, it is a fixed connection with a line, and the ears will not be torn. Also, it is easy to remove and fix again.

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

[0052] According to the above characteristics, by having an anti-slip portion on the inner surface of the clip piece, the clip piece will not fall off from the inner wall frame.

[0053] (Third feature) The inner wall panel according to the first feature, characterized in that the anti-slip portion has a saw blade shape.

[0054] According to the above characteristics, since the anti-slip portion has a saw blade shape, the saw blade bites into the film and the inner wall frame, and the clip piece will not fall off from the inner wall frame.

[0055] (Fourth feature) The clip pieces are incombustible, and the inner 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. Among the clip pieces, the length of the vertically long clip pieces fixed to the vertical frame members is substantially the same as the length of the vertical frame members, and among the clip pieces, the length of the horizontally long clip pieces fixed to the horizontal frame members is substantially the same as the length of the horizontal frame members. The inner wall panel is characterized in that the vertically long clip pieces and the horizontally long clip pieces are connected, and is any one of the first to third features.

[0056] According to the above features, the clip pieces are incombustible, and the inner wall frame is formed by a pair of vertical frame members on the left and right and a pair of horizontal frame members on the top and bottom. Among the clip pieces, the length of the vertically long clip pieces fixed to the vertical frame members is substantially the same as the length of the vertical frame members, and among the clip pieces, the length of the horizontally long clip pieces fixed to the horizontal frame members is substantially the same as the length of the horizontal frame members. Since the vertical clip pieces and the horizontal clip pieces are connected, even when the inner wall frame catches fire, the inner wall will not collapse, and the clip pieces can stand on their own as the inner wall frame and will not collapse.

[0057] (The fifth feature) An inner wall heat insulation structure using the inner wall panel according to any one of the first to fourth features, wherein the inner wall panels are arranged continuously, and a joint heat insulation material for filling a vertical joint generated between the heat insulation materials with ears of adjacent inner wall panels is arranged on the outdoor side of the clip pieces, and the heat insulation materials with ears and the joint heat insulation materials are arranged alternately and continuously in the horizontal direction.

[0058] According to the above features, the inner wall panels are arranged continuously along the framework supporting the building, and a joint heat insulation material for filling a vertical joint generated between the heat insulation materials with ears of adjacent inner wall panels, which fills the gap between the framework and the outdoor side surface of the clip pieces, is arranged.
