Description

[Technical Field]

[0001] The invention disclosed in this application relates to a heat insulating material fixing device used in a heat insulating construction method for the periphery of a building having a framework structure, and a heat insulating structure constructed using the heat insulating material fixing device. [Background technology]

[0002] A well-known thermal insulation method for the outer periphery of a building with a steel frame structure involves erecting an interior wall base panel, which integrates a frame and insulating material, within the structural plane of the framework surrounded by the outer periphery columns and beams, or slightly inside the structural plane, and then applying an interior wall finishing material such as gypsum board or wallpaper to the interior wall base panel. Additionally, insulating material is also laid or erected on the exterior side of the interior wall base panel, thereby forming a double layer of insulating material inside and outside, thereby improving the building's insulating performance. The frame of the interior wall base panel is made of wood or lightweight steel, and the insulating material attached to the interior wall base panel is often a board-shaped insulating material made of a foamed resin molded product such as polystyrene foam, polyethylene foam, rigid urethane foam, or phenolic foam.

[0003] In addition to the board-shaped insulation materials mentioned above, fiber-based insulation materials, which are formed into a flexible mat by filling inorganic fibers such as glass wool or rock wool into a bag made of resin film, are also commonly used as insulation materials placed on the outdoor side of the interior wall base panel. When insulation materials placed on the outdoor side are placed in contact with the back surface of the exterior wall material, condensation occurs between the exterior wall material and the insulation material, so a ventilation space is provided between the two. The present applicant has also proposed and put into practical use a ventilated insulation construction method (ventilated insulation structure, wall structure, etc.) for the outer periphery having such double insulation layers inside and outside and a ventilation space behind the exterior wall material, for example, in Patent Documents 1 to 9.

[0005] Because flexible, mat-like fiber insulation cannot stand on its own, it is fastened to the frame of the building frame or the interior wall base panel using screws or adhesive tape. However, if the interior wall base panel is made of foamed resin or if the building frame is made of steel, it is difficult to install the fiber insulation using screws or tape. Furthermore, if a construction method that does not use an interior wall base panel is used, it is difficult to position the insulation so that an appropriate ventilation space is secured between the back surface of the exterior wall material and the insulation.

[0006] The invention disclosed in this application was conceived to further improve the workability of the conventional thermal insulation construction method described above, and aims to provide an insulation material fixing device with excellent workability that can fix and hang fiber-based insulation material to beams on the upper floor when the insulation material is used as the insulation material behind the exterior wall material, and an insulation structure using the insulation material fixing device. [Means for solving the problem]

[0007] In order to achieve the above-mentioned object, the invention disclosed in this application is an insulation material fixing device for fastening a flexible insulation material to a beam material, which is configured by combining an insulation material hanger attached to the insulation material side and a beam fixing device attached to the beam material side, and the insulation material hanger includes a hanging shaft portion attached to the insulation material so as to penetrate the insulation material in the thickness direction, a flange-shaped hook portion provided at one end of the hanging shaft portion and wider than the hanging shaft portion, and a flange-shaped hook portion provided at the other end of the hanging shaft portion. The beam fixing device has a beam fixing base attached to the beam material and a hanging hanging portion extending away from the beam fixing base, and the hanging hanging portion has a hanging groove of a width that allows the hanging shaft of the insulation material hanging device to be loosely inserted and that can hang the flange-shaped hanging portion, one end of which opens at the edge of the hanging hanging portion and the other end of which is closed within the hanging hanging portion, thus adopting a basic configuration.

[0008] Furthermore, the invention disclosed in this application employs an additional configuration in which the beam fixing base of the insulation fixing device is provided with a clip portion that can engage with the flange of a beam made of shaped steel.

[0009] Furthermore, the invention disclosed in this application employs an additional configuration in which the beam fixing device in the heat insulating material fixing device has the beam fixing base and the hanging attachment portion formed separately.

[0010] Furthermore, the invention disclosed in this application employs an additional configuration in which a height difference is provided in the hanging hanging portion, and the closed end of the hanging groove is located at a position lower than at least one of the open end or the middle portion of the hanging groove.

[0011] Furthermore, the invention of the thermal insulation structure disclosed in this application is characterized in that the thermal insulation hanger of the thermal insulation fixture having the above-mentioned basic configuration or additional configuration is attached to the upper edge of the thermal insulation, the beam fixing device is attached to the beam that constitutes the framework of the main frame, and the thermal insulation hanger is hooked to the beam fixing device, so that the thermal insulation is placed between the framework of the main frame and the exterior wall material that is placed on the outdoor side, in a state where it is hung from the beam. [Effects of the Invention]

[0012] By using the insulation material fixing device configured as described above, flexible insulation material can be fastened to beam material with simple work that does not require special techniques or tools, thereby improving the workability of the insulation material.

[0013] Furthermore, with this insulation structure using the insulation fixing device, insulation is hung and placed on the outdoor side of the framework, and a ventilated insulation structure on the periphery that forms a ventilation space between the insulation and the exterior wall material can be constructed extremely efficiently.

DETAILED DESCRIPTION OF THE INVENTION

[0015] Embodiments of the present invention are described below with reference to the drawings. The thermal insulation structure described below corresponds to a ventilated thermal insulation structure for the periphery of a steel frame building, in which thermal insulation is placed on the outdoor side of the building frame and a ventilation space is formed between the thermal insulation and the exterior wall material. The thermal insulation material is typically a fiber-based thermal insulation material formed by filling inorganic fibers such as glass wool or rock wool into a resin film bag and forming it into a flexible mat shape. However, this invention is applicable not only to thermal insulation materials primarily composed of inorganic fibers, but also to thermal insulation materials formed into a mat or board shape that is flexible (expandable) in the thickness direction and bending direction, such as soft foamed resin or natural materials (cellulose fiber, wool breath, recycled felt, etc.). A key feature of this invention resides in an insulation material fastener suitable for fastening and suspending such thermal insulation material to beams on the upper floor.

[0016] 1 to 4 show a heat insulation material fixing device according to a first embodiment of the invention disclosed in this application, and a method of installing heat insulation material using the heat insulation material fixing device. This heat insulation material fixing device 1 is configured by combining an heat insulation material hanger 2 attached to the heat insulation material 7 side and a beam fixing device 3 attached to the beam material 8 side.

[0017] The insulation hanger 2 is a member including a round bar-shaped hanging shaft 21, a flange-shaped hooking portion 22 provided at one end of the shaft 21, and a hanging receiver 23 provided at the other end. In the illustrated embodiment, the hanging shaft 21 and the flange-shaped hooking portion 22 are formed integrally, and the hanging receiver 23 is formed as a separate member that can be attached to the hanging shaft 21 later.

[0018] In the illustrated embodiment, the flange-shaped hooking portion 22 has a substantially circular planar shape. However, as long as it is sufficiently wider than the outer diameter of the hanging shaft portion 21, it may be formed into a rectangular or other polygonal shape, an ellipse, or the like.

[0019] In the illustrated embodiment, suspension receiver 23 is formed in the shape of a short column with a substantially D-shaped cross section, obtained by cutting off a portion of a cylinder in a flat shape along the axial direction. Near the center of the curved outer surface (opposite the flat portion), fitting hole 24 is formed for inserting the other end of suspension shaft 21. Note that suspension receiver 23 may have any shape as long as it can appropriately support the load of thermal insulation material 7, and may be, for example, spherical, plate-like, polygonal column-like, etc.

[0020] Meanwhile, pointed tip 25 having a barb for preventing it from coming off is formed on the other end of hanging shaft 21. As shown in FIG. 2 , pointed tip 25 is pierced into thermal insulation 7, penetrating hanging shaft 21 in the thickness direction of thermal insulation 7, and hanging receiver 23 is fitted onto pointed tip 25 protruding on the opposite side, thereby attaching thermal insulation hanger 2 to thermal insulation 7. The length of hanging shaft 21 is preferably set so that thermal insulation 7 is slightly compressed in the thickness direction when attached. The shape of pointed tip 25 and fitting hole 24 can be changed as appropriate as long as they can be easily fitted together by hand and provide a fitting force that is strong enough to prevent them from easily coming off due to the weight of thermal insulation 7. It is safer if the other end of hanging shaft 21 (pointed tip 25) does not protrude on the opposite side of hanging receiver 23, but multiple fitting positions may be provided depending on the thickness of thermal insulation 7 as long as safety is not compromised.

[0021] Note that the insulation material suspension device 2 can also be configured such that suspension shaft 21 and suspension receiver 23 are integrally formed, and flange-shaped hooking portion 22 is formed as a separate piece that can be attached later, and attached to the opposite side of the insulation material 7. Furthermore, suspension shaft 21, flange-shaped hooking portion 22, and suspension receiver 23 can all be formed as separate pieces.

[0022] The beam fixing device 3 comprises a beam fixing base 4 attached along the lower end surface of the beam material 8, and a hanging attachment portion 5 extending below the beam material 8 and spaced slightly apart from the beam fixing base 4.

[0023] The beam fixing base 4 in the illustrated embodiment is a strip plate made of spring steel or the like, with clip portions 41, 42 provided at both ends thereof that can engage with a bottom flange 81 (see FIG. 3) of a beam 8 made of H-shaped steel or the like. To facilitate attachment to the bottom flange 81, the clip portion 41 on one side (the outdoor side) is formed to have a larger insertion dimension, while the clip portion 42 on the other side (the indoor side) is formed to have a smaller insertion dimension, and a finger hook 43 protrudes from the clip portion 42 on the other side. Note that the clip portion may be provided so as to engage with only one of the outdoor side or the indoor side of the beam 8.

[0024] The hanging attachment portion 5 in the illustrated embodiment is formed by bending a strip made of thin steel plate or the like. The hanging attachment portion 5 comprises a joint base 51 fixed to the underside of the beam fixing base 4, a hanging portion 52 extending downward from one edge of the joint base 51 near one side of the clip portion 41, an inclined portion 53 gently sloping downward from the lower edge of the hanging portion 52 toward the other side (indoor side), and a horizontal portion 54 extending substantially horizontally from the lower edge of the inclined portion 53 toward the other side (indoor side) and facing the beam fixing base 4 substantially parallel to the beam fixing base 4. The opposing distance between the beam fixing base 4 and the horizontal portion 54 is set to be slightly greater than the height of the flange-shaped hook portion 22 of the insulation hanger 2.

[0025] Then, hanging groove 55 for hanging insulation hanger 2 on this hanging hanging portion 5 is formed from horizontal portion 54 to inclined portion 53. Hanging groove 55 has a width that is slightly larger than the outer diameter of hanging shaft portion 21 of insulation hanger 2 and sufficiently smaller than the outer diameter of flange-shaped hanging portion 22. Hanging groove 55 extends in a generally J-shape in plan view from open end 56 formed on the edge of horizontal portion 54, passes through inclined portion 53, and is positioned so that closed end (terminal end) 57 returns to near the middle of horizontal portion 54.

[0026] Beam fastener 3 configured in this manner is attached to bottom flange 81 of beam 8 with its longitudinal direction facing the direction intersecting the axis of beam 8, as shown in FIG. 3 . Then, the upper edge of insulation 7 with insulation hanger 2 attached is curved so that flange-shaped hooking portion 22 faces upward, and suspension shaft 21 is inserted into hanging groove 55 of suspension hanging portion 5. Suspension shaft 21 inserted into open end 56 of horizontal portion 54 is moved along hanging groove 55, passing through inclined portion 53 once, and then pushed into closed end 57 of horizontal portion 54, where flange-shaped hooking portion 22 is hooked onto closed end 57. When insulation hanger 2 is positioned on horizontal portion 54 of suspension hanging portion 5 using such hanging groove 55, insulation hanger 2, which receives the weight of insulation 7, does not easily move toward inclined portion 53, so that insulation hanger 2 can be reliably prevented from slipping out of hanging groove 55 and falling off.

[0027] 5 to 8 show a heat insulation material fixing device according to a second embodiment of the invention disclosed in the present application, and a method for installing heat insulation 7 using the heat insulation material fixing device. This heat insulation material fixing device 1 is also configured by combining an heat insulation material hanger 2 attached to the heat insulation material 7 side and a beam fixing device 3 attached to the beam material 8 side. Since the basic configuration is the same as that of the first embodiment described above, common reference numerals are used for components that are substantially the same as those of the first embodiment, and detailed explanations will be omitted, with the explanation focusing on the differences.

[0028] Similar to the first embodiment, the insulation hanger 2 of the second embodiment includes a round bar-shaped hanging shaft 21, a flange-shaped hooking portion 22 provided at one end of the shaft, and a hanging receiver 23 provided at the other end, but hanging receiver 23 is formed in the shape of a large diameter disk. Similar to the first embodiment, hanging shaft 21 and flange-shaped hooking portion 22 are formed integrally, and hanging receiver 23 is formed as a separate element that can be attached to hanging shaft 21 later.

[0029] The beam fixing device 3 of the second embodiment also has a beam fixing base 4 and a hanging hanging portion 5, similar to the first embodiment, but differs from the first embodiment in that the beam fixing base 4 and the hanging hanging portion 5 are formed separately.

[0030] In the middle section of the beam fixing base 4 near the clip section 41 on one side, the beam fixing base 4 is bent in a stepped shape by the thickness of the joint base 51 of the hanging hanging part 5, and an engagement section 45 with a slit 44 opened on one side is formed. Meanwhile, the joint base 51 of the hanging hanging part 5 is formed longer than in the first embodiment, and the joint base 51 is inserted into the slit 44 and held on the engagement section 45, thereby integrating the hanging hanging part 5 and the beam fixing base 4. The shape of the hanging groove 55 formed in the hanging hanging part 5 is the same as in the first embodiment.

[0031] In this way, when the beam fixing base 4 and the hanging hanging part 5 are formed separately, as shown in Figures 6 to 8, the insulation hanger 2 attached to the insulation material 7 can be hung in advance in the hanging groove 55 of the hanging hanging part 5, and then raised to the height of the beam 8 to engage with the beam fixing base 4 attached to the beam 8. The engagement means between the beam fixing base 4 and the hanging hanging part 5 formed separately is not limited to the illustrated form, and may be formed by combining appropriate notches, irregularities, grooves, etc.

[0032] 9 shows a heat insulating material fastener 1 according to a third embodiment of the invention disclosed in the present application. (a) is a side view, and (b) is a bottom view of a beam fastener 3. In this embodiment, the suspension receiver 23 of the heat insulating material hanger 2 is formed in a shape similar to that of a cylinder with a generally octagonal cross section cut approximately in half along a plane including its axis, and is attached so as to support the heat insulating material 7 along its periphery. Meanwhile, the beam fastener 3 has a clip-shaped beam fixing base 4 that clamps the bottom flange 81 on one side of the beam 8, and the beam fixing base 4 and the suspension hanging portion 5 are formed so as to be continuous with one strip of plate.

[0033] Hanging hanging portion 5 comprises hanging portion 52 extending downward by a short distance from the lower side of beam fixing base 4, horizontal portion 54 extending substantially horizontally from the lower edge of hanging portion 52 toward the indoor side, inclined portion 53 extending gently upward from the indoor side edge of horizontal portion 54 toward the indoor side, and second horizontal portion 58 extending a short distance from the upper edge of inclined portion 53 toward the indoor side. Hanging groove 55 for hanging insulation hanger 2 on hanging hanging portion 5 is formed so as to extend from open end 56 formed on the edge of second horizontal portion, via inclined portion 53, to near the middle of horizontal portion 54, then bends into a substantially L-shape before reaching closed end (terminal end) 57. Even when insulation hanger 2 is hung in hanging groove 55 like this, a hanging state in which insulation hanger 2 does not easily come out of hanging groove 55 can be achieved.

[0034] Figure 10 shows a modified example of the hanging hanging part 5. This hanging hanging part 5 is simpler than the form in Figure 9, and is composed of only two parts: a hanging part 52 that extends downward from a clip-shaped beam-fixing base 4, and an inclined part 53 that extends gently upward from the lower edge of hanging part 52 toward the indoor side. Hanging groove 55 for hanging the insulation material hanger 2 on this hanging hanging part 5 is formed so that it extends from an open end 56 formed on the edge of inclined part 53 in a direction that descends inclined part 53, bends in a substantially L-shape, and reaches a closed end (terminal end) 57. When the insulation material hanger 2 is hung on such hanging groove 55, hanging shaft 21 is held at a slight angle, but even with this form, a hanging state in which the insulation material hanger 2 does not easily come out of hanging groove 55 can be achieved.

[0035] The shapes of the hanging hooking portion 5 and the hanging groove 55 are not limited to the shapes shown in the example, and can be modified in various ways as long as the same hanging state as described above can be obtained. Basically, if an appropriate height difference is provided in the hanging hooking portion 5 by using the inclined portion 53 or the like, and the closed end 57 of the hanging groove 55 is located lower than the open end 56 or an intermediate portion, the insulation hanger 2 will not return to the open end 56. Also, by providing an appropriate bend or the like in the planar shape of the hanging groove 55, it is possible to prevent the insulation hanger 2 from slipping out even with a configuration that has only a flat portion with no height difference.

[0036] The insulation structure described above, in which insulation 7 is suspended below beams 8 via insulation fixtures 1, allows the non-self-supporting, flexible insulation 7 to be positioned vertically along the framework of the building frame without being fastened to the frame of the interior wall base panel 6 (see Figure 3) or the foamed resin molding. The suspended insulation 7 can be installed in a size that can cover the entire height from the beams 8 on the upper floor to the beams on the lower floor (or foundation, etc.: not shown) with just one sheet, resulting in high installation efficiency. No special techniques or tools are required for installation. Furthermore, the suspended insulation 7 easily adapts to deformations in the framework caused by external forces such as earthquakes, eliminating the risk of breakage or damage.

[0037] The upper edge of the insulation 7 curves to fit along the lower end surface of the beam 8, sealing the gap with the beam 8 (the insulation 7 in areas where the insulation hanger 2 is not attached abuts against the beam 8 without being compressed in the thickness direction), so insulation defects or insufficiency are unlikely to occur below the beam 8. Furthermore, as shown in Figure 4, if the vertical side edges of adjacent insulation materials 7 are overlapped by an appropriate width when they are installed, the periphery of the building can be surrounded without any gaps.

[0038] Furthermore, this insulation material fixing device 1 can also be attached to beams other than H-shaped steel beams and other beam-like horizontal members (including wood, etc.). The "beam" described in this specification and claims encompasses such horizontal members. The form of the beam fixing base 4 can be modified as appropriate depending on the cross-sectional shape of the beam, and the fixing means to the beam is not limited to the clips 41 and 42 shown as examples. For example, it can be fastened by engaging with a round hole formed in the beam, by fastening with bolts and nuts, or, in the case of wood, by fastening with screws or nails.

[0039] 11 shows a form in which beam fastener 3 according to yet another modification is attached to the side of beam 80 made of wood with a rectangular cross section. The illustrated beam fastener 3 has flat beam fixing base 4 that is fixed with a screw to one side of beam 80, and the lower end of beam fixing base 4 is folded upward to form hanger hanging portion 5. Hanging groove 55 for hanging insulation hanger 2 is formed so as to extend downward from open end 56 formed on the upper edge of hanger hanging portion 5 to closed end (terminal) 57. When hanging shaft 21 of insulation hanger 2 is hung sideways in such hanging groove 55, a hanging state in which the upper edge of insulation 7 does not bend can be achieved.

[0040] By placing appropriate spacers (not shown) or the like at appropriate intervals between the insulation material 7 suspended outside the framework and the exterior wall material 9 (see Figure 3), the insulation material 7 can be easily kept separate from the exterior wall material 9. In this way, a ventilated and insulating structure can be suitably realized around the perimeter, with a ventilation space on the back side of the exterior wall material 9, preventing condensation inside the wall and optimizing insulation efficiency.

The names of elements used in the claims and the specification are for convenience in making the invention easier to understand, and the names do not unnecessarily limit the concepts or properties of the elements.
