Description

Technical Field

[0001] The invention disclosed in the present application relates to a heat insulation material fixture used in a heat insulation method for the outer periphery of a building having a frame structure, etc., and a heat insulation structure constructed using the heat insulation material fixture.

Background Art

[0002] As a heat insulation method adopted for the outer periphery of a building having a steel frame structure, an inner wall base panel in which a frame body and a heat insulation material are integrated is built within the structure plane of the building frame surrounded by column members and beam members on the outer periphery or slightly on the indoor side of the structure plane, and an inner wall finishing material such as a gypsum board or wallpaper is applied to the inner wall base panel. At the same time, a heat insulation material is also overlaid or built on the outdoor side of the inner wall base panel to form an inner and outer double heat insulation layer, thereby improving the heat insulation performance of the building. A heat insulation method is known. The frame body of the inner wall base panel is formed using wood or lightweight steel frame materials, and the heat insulation material assembled to the inner wall base panel is often a board-shaped heat insulation material made of a foamed resin molded body such as polystyrene foam, polyethylene foam, rigid urethane foam, or phenolic foam.

[0003] In addition to the board-shaped heat insulation material similar to the above-mentioned one, a fibrous heat insulation material formed into a flexible mat shape by filling inorganic fibers such as glass wool or rock wool into a bag made of a resin film is also frequently used for the heat insulation material arranged on the outdoor side of the inner wall base panel. When the heat insulation material arranged on the outdoor side is arranged in contact with the back surface of the outer wall material, condensation occurs between the outer wall material and the heat insulation material, so a ventilation space is provided between the two. The applicant of the present application has also proposed and put into practical use a ventilation heat insulation method (ventilation heat insulation structure, wall structure, etc.) for the outer periphery having such an inner and outer double heat insulation layer and a ventilation space on the back of the outer wall material in, for example, Patent Documents 1 to 9, etc.

Patent Document 1

[0005] The flexible mat-like fibrous heat insulating material cannot stand on its own, so it is fastened to the frame of the building frame or the inner wall base panel using screws or adhesive tapes. However, when the inner wall base panel is a foamed resin molded body or the building frame is a steel frame, it is difficult to construct the fibrous heat insulating material by screwing or taping. In addition, when adopting a construction method that does not use an inner wall base panel, it is difficult to position the heat insulating material so as to secure an appropriate ventilation space between the back surface of the outer wall material and the heat insulating material.

[0006] The invention disclosed in the present application was conceived in order to further improve the workability of the conventional heat insulation construction method. When using a fibrous heat insulating material as the heat insulating material behind the outer wall material, an object of the present invention is to provide a heat insulating material fixing tool having excellent workability that can fix the heat insulating material to the beam material on the upper floor and suspend it, and a heat insulating structure using the heat insulating material fixing tool. [Means for Solving the Problems]

[0007] In order to achieve the above object, the invention disclosed in the present application is a heat insulation material fixture for attaching a flexible heat insulation material to a beam member, which comprises a suspension tool attached to the beam member and protruding from the beam member, and a suspension receiver coupled to the suspension tool. The suspension tool includes a suspension shaft portion that is mounted on the heat insulation material so as to penetrate the heat insulation material in the thickness direction, a beam attachment portion provided at one end of the suspension shaft portion and attached to the beam member, and a receiver hanging portion provided at the other end of the suspension shaft portion and having a larger diameter than the suspension shaft portion. The suspension receiver includes a heat insulation material attachment portion that is attached to the heat insulation material, and a hanging groove having a width that allows the suspension shaft portion to pass through and a predetermined length that does not allow the receiver hanging portion to pass through is formed in the heat insulation material attachment portion, adopting the basic configuration as described above.

[0008] Furthermore, in the invention disclosed in the present application, the beam attachment portion in the heat insulation material fixture includes a flange-shaped portion that engages with the upper surface of the peripheral edge of the mounting hole formed in the flange of the beam member made of a shaped steel material. The additional configuration as described above is adopted.

[0009] Also, in the invention disclosed in the present application, the beam attachment portion in the heat insulation material fixture includes a clip portion that can engage with the flange of the beam member made of a shaped steel material, adopting the additional configuration as described above.

[0010] Furthermore, in the invention disclosed in the present application, the heat insulation material attachment portion in the heat insulation material fixture has a convex shape including a part of a circumferential surface or a polygonal column circumferential surface, adopting the additional configuration as described above.

[0011] Furthermore, in the invention disclosed in the present application, the hanging groove in the heat insulation material fixture is formed with its both ends closed inside the heat insulation material attachment portion, and an insertion port through which the receiver hanging portion can be inserted is formed at one end of the hanging groove, adopting the additional configuration as described above.

[0012] And the hanging groove can be formed such that at least a part of it extends in the circumferential direction of the heat insulation material attachment portion.

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

[0014] Furthermore, the invention disclosed in the present application adopts an additional configuration in which an opening through which the hanging groove can be visually recognized is formed in the hanging receiver on the back surface side of the heat insulating material attachment portion.

[0015] In addition, the invention of the heat insulation structure disclosed in the present application is characterized in that the hanging tool of the heat insulating material fixture having the above-described basic configuration or additional configuration is attached to the beam material so that the hanging shaft portion protrudes from the beam material, the heat insulating material is attached to the hanging tool so as to penetrate the hanging shaft portion in its thickness direction, and the hanging receiver is attached to the hanging tool by hooking the receiver hanging portion in the hanging groove, whereby the heat insulating material is suspended below the beam material in a state of being in contact with the beam material.

[0016] Furthermore, the invention of the heat insulation structure disclosed in the present application is characterized in that the hanging tool is attached along a beam material constituting a building frame, and the heat insulating material is disposed between the building frame and an outer wall material disposed on the outdoor side thereof.

Effects of the Invention

[0017] By using the heat insulating material fixture configured as described above, a flexible heat insulating material can be fastened to a beam material or the like by a simple operation that does not require special techniques or tools, etc., so that the workability of the heat insulating material is improved.

[0018] In addition, according to the heat insulation structure using this heat insulating material fixture, a so-called external heat insulation ventilation structure in which a heat insulating material is suspended and disposed on the outdoor side of the building frame and a ventilation space is formed between the heat insulating material and the outer wall material can be constructed extremely efficiently.

Mode for Carrying Out the Invention

[0020] Hereinafter, embodiments of the invention disclosed in the present application will be described with reference to the drawings. The heat insulation structure described below corresponds to a ventilation heat insulation structure for the outer peripheral part, in which a heat insulating material is arranged on the outdoor side of the building body and a ventilation space is formed between the heat insulating material and the outer wall material in the outer peripheral part of a building having a steel frame structure. As the heat insulating material, a fiber-based heat insulating material mainly formed by filling inorganic fibers such as glass wool or rock wool into a bag made of a resin film to form a flexible mat shape is used. However, the present invention is applicable not only to heat insulating materials mainly composed of inorganic fibers, but also to heat insulating materials formed into a mat shape or a board shape having flexibility (expansibility) in the thickness direction and the bending direction, such as soft foamed resins and natural materials (cellulose fibers, wool felt, recycled felt, etc.). And the main part of this invention lies in the heat insulating material fixture suitable for fastening and suspending such a heat insulating material to the beam member on the upper floor.

[0021] Figs. 1 to 3 show a heat insulating material fixture according to an embodiment of the invention disclosed in the present application and a heat insulation structure using the heat insulating material fixture. The heat insulating material fixture 1 is composed of a suspension tool 2 attached to a beam member 8 (see Fig. 2) and a suspension receiving tool 3 coupled from below the beam member 8 to the suspension tool 2. In the exemplary embodiment, mounting holes 82 for fastening or engaging various members are formed in advance in the lower flange 81 of the beam member 8 made of an H-shaped steel or the like, and here, the suspension tool 2 is attached using the mounting holes 82.

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

[0023] The suspension shaft portion 21 has, for example, a straight bar shape with a circular cross-section, and its length is set to be exactly the length that can penetrate through the heat insulating material 7 in a slightly compressed state in the thickness direction. The beam attachment portion 22 is formed as a flange portion 221 that is substantially rectangular in plan view in this form, and its maximum width is set to be sufficiently larger than the inner diameter of the mounting hole 82. The receiver hanging portion 23 is formed in an inverted conical shape having a pointed tip portion 24 at the tip, and the outer diameter of its bottom surface is set to be sufficiently larger than the outer diameter of the suspension shaft portion 21.

[0024] The suspension receiver 3 is a columnar hollow member in the illustrated embodiment, and at least substantially half (semicircular circumferential surface) of its peripheral surface constitutes a heat insulating material attachment portion 31 that is attached to the heat insulating material 7. A hanging groove 32 with a width that allows the suspension shaft portion 21 of the suspension tool 2 to be inserted and does not allow the receiver hanging portion 23 to be inserted, that is, a width larger than the outer diameter of the suspension shaft portion 21 and smaller than the outer diameter of the receiver hanging portion 23, is formed in the heat insulating material attachment portion 31 so that both ends thereof are closed within the heat 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 its length is formed to extend over about 1 / 4 to 1 / 3 of the entire circumferential length. And an insertion port 33 with an inner diameter that allows the receiver hanging portion 23 to be inserted is formed at one of the closed ends.

[0025] When attaching the heat insulating material 7, as shown in FIG. 2, first, the receiver hanging portion 23 and the suspension shaft portion 21 of the suspension tool 2 are inserted into the mounting hole 82 from above the lower flange 81 of the beam member 8 and projected below the lower flange 81. Then, the suspension tool 2 is held by the beam member 8 in a state where the beam attachment portion 22 (flange portion 221) is engaged with the upper surface of the peripheral edge portion of the mounting hole 82.

[0026] Subsequently, while lifting and bending the upper edge portion of the flexible heat insulating material 7, it is pressed against the lower side of the beam member 8, the receiver hanging portion 23 protruding below the beam member 8 is pierced into the heat insulating material 7, and the suspension shaft portion 21 is penetrated through the heat insulating material 7.

[0027] Thereafter, while supporting the heat insulating material 7, the hanging receiver 3 is applied to the heat insulating material 7, and the receiver hanging portion 23 is inserted into the insertion port 33 of the hanging groove 32. Then, when the hanging receiver 3 is rotated in the circumferential direction (counterclockwise in FIG. 2) along the hanging groove 32, the hanging groove 32 is hooked on the receiver hanging portion 23, and the hanging receiver 3 does not fall off. Thus, the heat insulating material 7 is suspended below the beam member 8 in a state where its upper edge portion is curved along the heat insulating material abutting portion 31 of the hanging receiver 3.

[0028] According to the heat insulation structure in which the heat insulating material 7 is suspended below the beam member 8 using such a heat insulating material fixing tool, the flexible heat insulating material 7 having no self-standing property can be arranged in the vertical direction along the building frame without being fastened to the frame of the inner wall base panel 6 (see FIG. 2) or the foamed resin molded body. The heat insulating material 7 to be suspended can be constructed in a size that can cover the height from the beam member 8 on the upper floor to the beam member on the lower floor (or a base, etc.: not shown) with a single sheet, so the construction efficiency is good. Special techniques and tools are not required for the construction. Furthermore, the suspended heat insulating material 7 can easily follow the deformation of the building frame due to external forces such as earthquakes, so there is no worry of breakage or damage.

[0029] The upper edge portion of the heat insulating material 7 is curved along the lower end surface of the beam member 8 to close the gap with the beam member 8, so heat insulation deficiency or insufficient heat insulation is less likely to occur below the beam member 8. Furthermore, as shown in FIG. 3, if the vertical side edge portions of adjacent heat insulating materials 7 are overlapped with an appropriate width for construction, the outer peripheral portion of the building can be surrounded without gaps.

[0030] And if appropriate spacers (not shown) etc. are arranged at appropriate intervals between the heat insulating material 7 suspended outside the building frame and the outer wall material, the heat insulating material 7 can be easily separated from and held by the outer wall material. Thus, an external heat insulation ventilation structure having a ventilation space on the back side of the outer wall material can be preferably realized, and dew condensation prevention inside the wall and optimization of the heat insulation efficiency can be achieved.

[0031] However, if this heat insulation material fixture 1 is used, the hanging position of the heat insulation material 7 can be appropriately changed according to the structure of the building body, the construction site, etc., not limited to the form shown in FIG. 2. FIG. 4(a) shows a form in which the upper edge of the heat insulation material 7 is curved outward and suspended from the lower flange 81 on the outdoor side. FIG. 4(b) shows a form in which the upper edge of the heat insulation material 7 is curved inward and suspended from the lower flange 81 on the indoor side. FIG. 4(c) shows a form in which the upper edge of the heat insulation material 7 is curved outward and suspended from the lower flange 81 on the indoor side.

[0032] FIGS. 5 to 8 show other embodiments of the heat insulation material fixture 1. The basic configuration of combining the hanging tool 2 and the hanging receiving tool 3 in the embodiments exemplified below is the same as that of the foregoing embodiments. Therefore, the same reference numerals are assigned to the substantially identical components as those in the foregoing embodiments, and detailed descriptions thereof are omitted, and the description will be centered on the differences.

[0033] FIG. 5 shows a modification of the beam attachment portion 22 of the hanging tool 2. This beam attachment portion 22 is formed as a flange portion 222 having a substantially rectangular shape in plan view. However, if the maximum width of the flange portion 222 is sufficiently larger than the inner diameter of the mounting hole 82, it may be formed in other polygonal shapes, elliptical shapes, etc.

[0034] In this form, when the receiving tool hanging portion 23 and the hanging shaft portion 21 protruding below the beam member 8 are pressed against the heat insulation material 7, anti-drop means is provided to prevent the hanging tool 2 from escaping above the mounting hole 82. The exemplified anti-drop means is, for example, a pair of engaging springs 25 formed by bending a thin spring plate material or a spring wire into a V shape so that its width can elastically expand and contract. When one piece of these engaging springs 25 is attached to the side of the hanging shaft portion 21 and the other piece is projected outward so as to widen upward, when the hanging tool 2 is inserted into the mounting hole 82, the engaging spring 25 deforms inward, and when it passes through the mounting hole 82, it projects outward and engages with the lower surface of the peripheral edge portion of the mounting hole 82. By providing such anti-drop means, the workability when the hanging tool 2 is pierced and fixed to the heat insulation material 7 can be improved.

[0035] Note that the means for preventing detachment from the mounting hole 82 is not limited to such an engagement spring 25, and can be configured using an appropriate elastic member, uneven fitting, or the like. Also, although not shown in the drawings, a form in which the hanging tool 2 is inserted from below into the mounting hole 82 of the lower flange 81 of the beam member 8 and the detachment prevention means is engaged with the upper surface side of the peripheral portion of the mounting hole 82 can also be adopted.

[0036] FIG. 6 shows a clip portion 223 in which the beam attachment portion 22 of the hanging tool 2 can be engaged with the lower flange 81 of the beam member 8 from the side. By bending a thin strip made of spring steel plate, for example, shaping it as shown in the drawing, attachment independent of the position of the mounting hole 82 of the beam member 8 becomes possible. The clip portion 223 may be provided so as to engage with both edge ends on the outdoor side and the indoor side of the beam member 8.

[0037] FIG. 7 shows a modified example of the hanging groove 32 formed in the heat insulating material attachment portion 31 of the hanging receiver 3. The illustrated hanging groove 32 is formed so as to be continuously formed in a substantially L-shape from one end of a portion 32a extending in the circumferential direction of the heat insulating material attachment portion 31 having a circumferential surface shape to a portion 32b extending in a direction intersecting the circumferential direction (the generatrix direction of the circumferential surface). And an insertion port 33 is arranged at the terminal end of the portion 32b extending in the intersecting direction. If the hanging groove 32 is formed to be refracted in the middle in this way, it becomes easier to prevent the hanging receiver 3 from falling off from the hanging tool 2 due to rotation or displacement of the hanging receiver 3 after the construction of the heat insulating material 7. Also, in the form in which the hanging groove 32 is refracted, for example, as shown by an imaginary line (two-dot chain line) in the drawing, one end of the hanging groove 32 can be opened to the end surface or the like of the hanging receiving portion 3, and the opening edge can be used as the insertion port.

[0038] FIG. 8 shows a modified example of the hanging receiver 3. The illustrated hanging receiver 3 is formed such that a part of the circumferential surface is cut off in the generatrix direction, and the end surface has an arc shape of about 3 / 4 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 in a substantially semi-circular circumferential surface shape (a curved surface whose end surface has an arc shape of about 1 / 2 circle or more), the heat insulating material attachment portion 31 can preferably support the heat insulating material 7 along the curved surface.

[0039] And according to the exemplary form, it becomes possible to look inside the heat insulating material attachment part 31 from the cut opening 34. Thus, if the opening 34 is formed on the back side of the heat insulating material attachment part 31 so that the hanging groove 32 (particularly the position of the insertion port 33) can be visually recognized from the opening 34, the workability when inserting the receiver hanging part 23 penetrating the heat insulating material 7 into the insertion port 33 of the hanging groove 32 is remarkably improved. The opening 34 may be formed only in the middle part, not in the whole bus bar direction of the suspension receiver 3 as shown by the imaginary line (two-dot chain line) in FIG. 7, and may have an appropriate shape such as circular.

[0040] FIG. 9 shows still another modified example of the suspension receiver 3. The surface of the heat insulating material attachment part 31 can be a convex surface including not only the circumferential surface but also a polygonal column circumferential surface or a mountain-shaped surface as shown in FIGS. (a) to (c) thereof, as long as it is a shape that can be easily attached to the heat insulating material 7. In that case, the ridge line part is preferably formed to be rounded.

[0041] Note that this heat insulating material fixture 1 can also be attached to a beam material other than the H-shaped steel and other horizontal members similar to the beam material (including wood, etc.). The "beam material" described in the claims also includes such horizontal members. The form of the beam attachment part 22 may be appropriately changed according to the cross-sectional shape of the beam material, and is not limited to the form by the flange parts 221 and 222 and the clip part 223 as exemplified. For example, it can be bolted and fastened to the attachment hole 82 formed in the beam material 8, or if it is wood, it can be fixed with screws or nails.

[0042] FIG. 10 shows a form in which a heat insulating material fixture is attached to the side surface of a beam material 80 made of wood with a rectangular cross section. In the exemplary form, the suspension tool 2 has the suspension shaft part 21 facing sideways and is screwed to one side surface of the beam material 80. If the suspension shaft part 21 is made to penetrate the heat insulating material 7, the heat insulating material 7 is arranged along the side surface of the beam material 80, and the suspension receiver 3 is hooked on the suspension shaft part 21, a suspension state in which the upper edge part of the heat insulating material 7 does not bend can be realized.

However, the technical scope of the invention disclosed in this application should not be construed in a limited manner by the illustrated embodiments, but should be conceptually construed based on the description in the claims.
