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]

[0012] The hooking groove may be formed so that at least a portion thereof extends in the circumferential direction of the heat insulating material splicing portion.

[0013] Furthermore, the hooking groove may be formed so as to extend continuously from one end of a circumferentially extending portion of the heat insulating material splicing portion in a direction intersecting the circumferential direction.

[0016] Furthermore, the invention of the thermal insulation structure disclosed in this application is characterized in that the suspension device is attached along the beams that make up the framework, and the thermal insulation material is placed between the framework and the exterior wall material that is placed on the outdoor side.

DETAILED DESCRIPTION OF THE INVENTION

[0020] 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.

[0021] 1 to 3 show a heat insulation material fixing device according to one embodiment of the invention disclosed in the present application, and a heat insulation structure using the heat insulation material fixing device. Heat insulation material fixing device 1 is configured by combining a hanger 2 attached to beam 8 (see FIG. 2) with a hanger receiver 3 coupled to hanger 2 from below beam 8. In the illustrated embodiment, mounting holes 82 for fastening or engaging various members are formed in advance in bottom flange 81 of beam 8 made of H-shaped steel or the like, and here, hanging device 2 is attached using mounting hole 82.

[0022] Suspension tool 2 is a member having suspension shaft portion 21 having a predetermined length, beam attachment portion 22 provided at one end of suspension shaft portion 21, and receiver hanging portion 23 provided at the other end of suspension shaft portion 21. In the illustrated embodiment, these are integrally formed, but some or all of them may be formed separately.

[0023] The suspension shaft 21 is, for example, in the shape of a straight rod with a circular cross section, and its length is set so that it can just penetrate the insulation 7 when it is slightly compressed in the thickness direction. In this form, the beam attachment portion 22 is formed as a flange-shaped portion 221 that is roughly rectangular in plan view, and its maximum width is set so that it is sufficiently larger than the inner diameter of the mounting hole 82. The receiver hanging portion 23 is formed in the shape of an inverted cone with a pointed tip 24 at its tip, and the outer diameter of its bottom surface is set so that it is sufficiently larger than the outer diameter of the suspension shaft 21.

[0024] In the illustrated embodiment, the suspension receiver 3 is a cylindrical hollow member, and at least approximately half of its circumferential surface (semicircular circumferential surface) constitutes an insulating material attachment portion 31 that is attached to the insulating material 7. In this insulating material attachment portion 31, a hanging groove 32 is formed so that the suspension shaft portion 21 of the suspension device 2 can be inserted therethrough but the receiver hanging portion 23 cannot be inserted therethrough, in other words, the hanging groove 32 has a width that is larger than the outer diameter of the suspension shaft portion 21 and smaller than the outer diameter of the receiver hanging portion 23, and both ends of the hanging groove 32 are closed within the insulating material attachment portion 31. The hanging groove 32 in the illustrated embodiment extends in the circumferential direction near the middle in the axial length direction of the suspension receiver 3, and is formed so that its length spans approximately 1 / 4 to 1 / 3 of the entire circumferential length. An insertion opening 33 having an inner diameter that allows the receiver hanging portion 23 to be inserted therethrough is formed at one closed end.

[0025] When fastening thermal insulation material 7, as shown in FIG. 2 , first, receiver hanging portion 23 and hanging shaft portion 21 of hanging device 2 are inserted into mounting hole 82 from above bottom flange 81 of beam 8, and are made to protrude below bottom flange 81. Then, with beam attachment portion 22 (flange-shaped portion 221) engaged with the upper surface of the periphery of mounting hole 82, hanging device 2 is held by beam 8.

[0026] Next, the upper edge of the flexible heat insulating material 7 is lifted and curved while being pressed against the bottom of the beam material 8, and the receiver hanging part 23 protruding below the beam material 8 is pierced into the heat insulating material 7, and the hanging shaft part 21 is made to penetrate the heat insulating material 7.

[0027] Thereafter, while supporting the thermal insulation material 7, the hanging bracket 3 is placed against the thermal insulation material 7, and the bracket hooking portion 23 is inserted into the insertion opening 33 of the hanging groove 32. Then, when the hanging bracket 3 is rotated circumferentially (counterclockwise in FIG. 2 ) along the hanging groove 32, the hanging groove 32 hooks onto the bracket hooking portion 23, preventing the hanging bracket 3 from falling off. In this way, the thermal insulation material 7 is hung below the beam 8 with its upper edge curved so as to fit along the thermal insulation attachment portion 31 of the hanging bracket 3.

[0028] This type of insulation structure, in which insulation 7 is suspended below beams 8 using insulation fixtures, 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 2) 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 (or foundations, etc.; not shown) on the lower floor with just one sheet, resulting in efficient installation. No special techniques or tools are required for installation. Furthermore, the suspended insulation 7 easily conforms to deformations in the framework caused by external forces such as earthquakes, eliminating the risk of breakage or damage.

[0029] The upper edge of the insulation material 7 curves to fit the lower end surface of the beam 8, filling the gap with the beam 8, making it less likely that insulation defects or insufficiency will occur below the beam 8. Furthermore, as shown in Figure 3, 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.

[0030] By placing appropriate spacers (not shown) at appropriate intervals between the insulation material 7 suspended outside the framework and the exterior wall material, the insulation material 7 can be easily kept separate from the exterior wall material. This makes it possible to effectively realize an external insulation and ventilation structure with a ventilation space on the back side of the exterior wall material, preventing condensation inside the wall and optimizing insulation efficiency.

[0031] However, by using this insulation material fixing device 1, the hanging position of the insulation material 7 can be changed as appropriate depending on the structure of the building frame, the installation location, etc., without being limited to the configuration shown in Fig. 2. Fig. 4(a) shows a configuration in which the upper edge of the insulation material 7 is curved toward the outside and hung from the lower flange 81 on the outside. Fig. 4(b) shows a configuration in which the upper edge of the insulation material 7 is curved toward the inside and hung from the lower flange 81 on the inside. Fig. 4(c) shows a configuration in which the upper edge of the insulation material 7 is curved toward the outside and hung from the lower flange 81 on the inside.

[0032] 5 to 8 show other embodiments of the heat insulating material fixing device 1. In the embodiments exemplified below, the basic configuration of combining the hanging tool 2 and the hanging receiver 3 is similar to that of the previously described embodiment, so components that are substantially the same as those in the previously described embodiment are given the same reference numerals, detailed explanations are omitted, and the explanation will focus on the differences.

[0033] 5 shows a modified example of beam attachment portion 22 in suspending device 2. This beam attachment portion 22 is formed as a flange-shaped portion 222 that is generally rectangular in plan view. However, flange-shaped portion 222 may be formed in other polygonal or elliptical shapes, etc., as long as the maximum width thereof is sufficiently larger than the inner diameter of mounting hole 82.

[0034] In this embodiment, a retaining means is provided to prevent suspension tool 2 from escaping above mounting hole 82 when thermal insulation material 7 is pressed against receiver hooking portion 23 and suspension shaft portion 21 that protrude downward from beam 8. The illustrated retaining means is a pair of engaging springs 25 formed, for example, by bending a thin spring plate or spring wire into a V-shape so that its width can elastically expand and contract. If one end of these engaging springs 25 is attached to the side of suspension shaft portion 21 and the other end is made to bulge outward so as to expand upward, engaging spring 25 deforms inward when suspension tool 2 is inserted into mounting hole 82, and bulges outward after passing through mounting hole 82, engaging with the underside of the peripheral edge of mounting hole 82. Providing such a retaining means can improve the ease of operation when piercing and fastening suspension tool 2 into thermal insulation material 7.

[0035] Note that the retaining means for mounting hole 82 is not limited to such engaging spring 25, and can be configured using an appropriate elastic member, concave-convex fitting, etc. Although not shown in the figures, it is also possible to employ a configuration in which suspending device 2 is inserted into mounting hole 82 of lower flange 81 of beam 8 from below, and retaining means is engaged with the upper surface side of the peripheral edge of mounting hole 82.

[0036] 6 shows an example in which beam attachment portion 22 of suspension device 2 is configured as clip portion 223 that can engage with bottom flange 81 of beam 8 from the side. By shaping a thin strip made of spring steel plate, for example, as shown in the figure, fastening becomes possible that is not dependent on the position of mounting hole 82 of beam 8. Clip portion 223 may be provided so as to engage with both the outdoor and indoor edge ends of beam 8.

[0037] FIG. 7 shows a modified example of the hooking groove 32 formed in the heat insulating material attachment portion 31 of the hanging receiver 3. The illustrated hooking groove 32 is formed so as to continue in a generally L-shape from one end of portion 32a extending in the circumferential direction of the heat insulating material attachment portion 31, which has a circumferential surface shape, to portion 32b extending in a direction intersecting the circumferential direction (the generatrix direction of the circumferential surface). An insertion opening 33 is disposed at the end of portion 32b extending in the intersecting direction. Forming hooking groove 32 so as to bend midway in this manner makes it easier to prevent the hanging receiver 3 from falling off the hanging receiver 2 due to rotation or displacement of the hanging receiver 3 after the installation of the heat insulating material 7. Furthermore, in a configuration in which hooking groove 32 is bent, for example, one end of hooking groove 32 can be opened to an end face of the hanging receiver 3, and the edge of the opening can be used as the insertion opening, as shown by an imaginary line (two-dot chain line) in the figure.

[0038] 8 shows a modified example of the hanging receiver 3. In the illustrated hanging receiver 3, a portion of the circumferential surface is cut away in the generatrix direction, and the end face is formed to have an arc shape of approximately 3 / 4 of a circle. The hanging groove 32 is formed in a substantially L-shape near the center of the arc-shaped portion. Even if the entire circumferential surface is not continuous in this way, as long as there is at least a curved surface that is curved into a substantially semicircular surface (a curved surface whose end face is an arc shape of approximately 1 / 2 of a circle or more), the heat insulating material attachment portion 31 can suitably support the heat insulating material 7 along the curved surface.

[0039] According to the illustrated embodiment, it is possible to see inside the heat insulating material attachment portion 31 through the cut-out opening 34. In this way, by forming the opening 34 on the back side of the heat insulating material attachment portion 31 and configuring it so that the hanging groove 32 (particularly the position of the insertion opening 33) can be seen from the opening 34, the workability when inserting the receiver hanging portion 23 that has penetrated the heat insulating material 7 into the insertion opening 33 of the hanging groove 32 is significantly improved. As shown by the imaginary line (two-dot chain line) in Fig. 7, the opening 34 may be formed only in the middle portion rather than over the entire generatrix direction of the hanging receiver 3, and may be circular or have any other appropriate shape.

[0040] Fig. 9 shows yet another modified example of the hanging bracket 3. The surface of the heat insulating material attachment part 31 can be not only a circumferential surface, but also a convex surface including a polygonal prism circumferential surface or a mountain-shaped surface as shown in Fig. 9 (a) to (c), as long as it has a shape that allows it to be attached smoothly to the heat insulating material 7. In this case, it is preferable that the ridge parts are formed to be rounded.

[0041] This heat 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 the claims encompasses such horizontal members. The form of the beam attachment portion 22 can be changed appropriately depending on the cross-sectional shape of the beam, and is not limited to the flange portions 221, 222 and clip portion 223 shown as examples. For example, it is also possible to fasten the beam 8 to mounting holes 82 formed in the beam 8 with bolts and nuts, or to fasten the beam 8 to wood with screws or nails.

[0042] 10 shows a form in which a heat insulating material fixing device is attached to the side of beam 80 made of wood with a rectangular cross section. In the illustrated form, suspension device 2 is fixed with a screw to one side of beam 80 with suspension shaft 21 facing horizontally. By passing suspension shaft 21 through heat insulating material 7, aligning heat insulating material 7 along the side of beam 80, and hanging device 3 being hooked onto suspension shaft 21, a suspended state in which the upper edge of heat insulating material 7 does not bend can be achieved.

[0043] The above describes an invention in which an insulation material is suspended from a beam using an insulation material fixing device that combines a suspension tool and a suspension support.
