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 in the plane of the building frame surrounded by column members and beam members on the outer periphery or slightly on the indoor side of the plane, and an inner wall finishing material such as a plaster board or wallpaper is applied to the inner wall base panel. At the same time, a heat insulation material is also laminated 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, a fiber-based 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 behind the outer wall material in, for example, Patent Documents 1 to 9, etc.

Summary of the Invention

Problems to be Solved by the Invention

[0005] Since the mat-like fibrous heat insulating material having flexibility cannot stand on its own, 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. Further, 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 capable of fixing the heat insulating material to an upper floor beam member and suspending 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 is composed of a combination of a heat insulation material suspension tool attached to the heat insulation material side and a beam fixture attached to the beam member side. The heat insulation material suspension tool includes a suspension shaft portion mounted on the heat insulation material so as to penetrate the heat insulation material in the thickness direction, a flange-shaped latching portion provided at one end of the suspension shaft portion and wider than the suspension shaft portion, and a suspension receiving portion provided at the other end of the suspension shaft portion and wider than the suspension shaft portion. The beam fixture includes a beam fixing base portion attached to the beam member and a suspension hanging portion projecting so as to be separated from the beam fixing base portion. In the suspension hanging portion, a hanging groove having a width that allows the suspension shaft portion of the heat insulation material suspension tool to be loosely inserted and the flange-shaped latching portion to be latched is formed with one end opening at the edge of the suspension hanging portion and the other end closed inside the suspension hanging portion. The basic configuration is adopted as described above.

[0008] Furthermore, the invention disclosed in the present application adopts an additional configuration in which the beam fixing base portion in the heat insulation material fixture includes a clip portion that can engage with the flange of a beam member made of a shaped steel material.

[0009] Furthermore, the invention disclosed in the present application adopts an additional configuration in which the beam fixture in the heat insulation material fixture is formed such that the beam fixing base portion and the suspension hanging portion are separate bodies.

[0010] Furthermore, the invention disclosed in the present application adopts an additional configuration in which a height difference is provided in the suspension hanging portion, and the closed end of the hanging groove is provided at a position lower than at least one of the opening end or an intermediate portion of the hanging groove.

[0011] Further, in the invention of the heat insulation structure disclosed in the present application, the heat insulation material hanger of the heat insulation material fixture having the above-described basic configuration or additional configuration is attached to the upper edge portion of the heat insulation material, and the beam fixture is attached to a beam member constituting a building frame. The heat insulation material is suspended from the beam member by hanging the heat insulation material hanger on the beam fixture, and is characterized in that it is disposed between the building frame and an outer wall member disposed on the outdoor side thereof.

Effect of the Invention

[0012] By using the heat insulation material fixture configured as described above, a flexible heat insulation material can be fastened to a beam member by a simple operation that does not require special techniques or tools, etc., so that the workability of the heat insulation material is improved.

[0013] Further, according to the heat insulation structure using this heat insulation material fixture, a ventilation heat insulation structure for the outer peripheral portion in which a heat insulation material is suspended and disposed on the outdoor side of the building frame and a ventilation space is formed between the heat insulation material and the outer wall member can be constructed extremely efficiently.

Mode for Carrying Out the Invention

[0015] 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 periphery, in which a heat insulating material is disposed 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 periphery of a building having a steel frame structure. As the heat insulating material, a fibrous 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 fixing tool suitable for fastening and suspending such a heat insulating material to the beam member on the upper floor.

[0016] Figs. 1 to 4 show a heat insulation material fixture according to a first embodiment of the invention disclosed in the present application and a method for installing a heat insulation material using the heat insulation material fixture. This heat insulation material fixture 1 is configured by combining a heat insulation material suspension tool 2 attached to the heat insulation material 7 side and a beam fixture 3 attached to the beam member 8 side.

[0017] The heat insulation material suspension tool 2 is a member including a round bar-shaped suspension shaft portion 21, a flange-shaped latching portion 22 provided at one end thereof, and a suspension receiving portion 23 provided at the other end thereof. In the exemplary embodiment, the suspension shaft portion 21 and the flange-shaped latching portion 22 are integrally formed, and the suspension receiving portion 23 is formed as a separate body that can be retrofitted to the suspension shaft portion 21.

[0018] The flange-shaped latching portion 22 has a substantially circular planar shape in the exemplary embodiment. However, as long as it is sufficiently wider than the outer diameter of the suspension shaft portion 21, it may be formed in a rectangular or other polygonal shape, an elliptical shape, or the like.

[0019] The suspension receiving portion 23 is formed in a short columnar shape with a substantially D-shaped cross-section obtained by planarly cutting off a part of a cylinder along the axial direction in the exemplary embodiment. A fitting hole 24 for fitting the other end of the suspension shaft portion 21 is formed near the center of the outer peripheral curved surface (opposite side of the planar portion). Note that the shape of the suspension receiving portion 23 is arbitrary as long as it can appropriately support the load of the heat insulation material 7, and may be, for example, spherical, plate-shaped, polygonal columnar, or the like.

[0020] On one side, a pointed tip portion 25 having a retaining loop is formed at the other end of the suspension shaft portion 21. As shown in FIG. 2, when this pointed tip portion 25 is pierced into the heat insulating material 7 to penetrate the suspension shaft portion 21 in the thickness direction of the heat insulating material 7 and the suspension receiving portion 23 is fitted to the pointed tip portion 25 protruding to the opposite side, the heat insulating material suspension tool 2 is attached to the heat insulating material 7. The length of the suspension shaft portion 21 is preferably set such that the heat insulating material 7 is slightly compressed in the thickness direction in the attached state. The forms of the pointed tip portion 25 and the fitting hole 24 can be appropriately changed as long as they can be easily fitted by handwork alone and a fitting force is obtained such that they do not easily come out due to the load of the heat insulating material 7. Although it is safer that the other end (pointed tip portion 25) of the suspension shaft portion 21 does not protrude to the opposite side of the suspension receiving portion 23, a plurality of fitting positions corresponding to the thickness of the heat insulating material 7 may be provided within a range that does not impair the safety.

[0021] Note that the heat insulating material suspension tool 2 can also be configured such that the suspension shaft portion 21 and the suspension receiving portion 23 are integrally formed, and the flange-shaped latching portion 22 is formed as a separate body that can be attached later, and is attached from the opposite side to the heat insulating material 7. Further, the suspension shaft portion 21, the flange-shaped latching portion 22, and the suspension receiving portion 23 can all be formed as separate bodies.

[0022] The beam fixing tool 3 includes a beam fixing base portion 4 attached along the lower end surface of the beam member 8, and a suspension hanging portion 5 that projects below the beam member 8 so as to be slightly separated from the beam fixing base portion 4.

[0023] The beam fixing base portion 4 of the exemplary embodiment is provided with clip portions 41, 42 at both ends of a strip plate made of a spring steel plate or the like that can be engaged with the lower flange 81 (see FIG. 3) of the beam member 8 made of an H-shaped steel or the like. In order to facilitate attachment to the lower flange 81, the clip portion 41 on one side (outdoor side) is formed with a large swallowing dimension, and the clip portion 42 on the other side (indoor side) is formed with a small swallowing dimension, and a finger-hooking piece 43 projects 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 member 8.

[0024] The hanging part 5 of the exemplary embodiment is formed by bending a strip plate made of a thin steel plate or the like. The hanging part 5 includes a joint base 51 fixed to the lower surface of the beam fixing base 4, a hanging part 52 extending downward and short from one end edge of the joint base 51 near the clip part 41 on one side, an inclined part 53 gently descending and inclining from the lower end edge of the hanging part 52 toward the other side (indoors), and a horizontal part 54 extending substantially horizontally from the lower end edge of the inclined part 53 toward the other side (indoors) and facing substantially parallel to the beam fixing base 4. The facing interval between the beam fixing base 4 and the horizontal part 54 is set to be slightly larger than the height of the flange-like latching part 22 of the heat insulating material hanging tool 2.

[0025] And a hanging groove 55 for hanging the heat insulating material hanging tool 2 on the hanging part 5 is formed from the horizontal part 54 to the inclined part 53. The hanging groove 55 has a width slightly larger than the outer diameter of the hanging shaft part 21 of the heat insulating material hanging tool 2 and sufficiently smaller than the outer diameter of the flange-like latching part 22. The hanging groove 55 extends in a substantially J shape in plan view from the opening end 56 formed at the edge of the horizontal part 54, passes through the inclined part 53, and then is arranged such that the closed end (terminal end) 57 returns to near the middle of the horizontal part 54.

[0026] As shown in FIG. 3, the beam fixture 3 configured as described above is attached to the lower flange 81 of the beam member 8 with its longitudinal direction facing the direction intersecting the material axis of the beam member 8. Then, the upper edge part of the heat insulating material 7 equipped with the heat insulating material hanging tool 2 is curved with the flange-like latching part 22 facing upward, and the hanging shaft part 21 is inserted into the hanging groove 55 of the hanging part 5. The hanging shaft part 21 inserted into the opening end 56 of the horizontal part 54 is moved along the hanging groove 55, once passing through the inclined part 53 and then pushed into the closed end 57 of the horizontal part 54, and the flange-like latching part 22 is latched on the closed end 57. When the heat insulating material hanging tool 2 is arranged on the horizontal part 54 of the hanging part 5 by using such a hanging groove 55, the heat insulating material hanging tool 2 receiving the load of the heat insulating material 7 does not easily move to the inclined part 53 side, so it is possible to reliably prevent the heat insulating material hanging tool 2 from slipping out of the hanging groove 55 and falling off.

[0027] Figures 5 to 8 show a heat insulation material fixture according to a second embodiment of the invention disclosed in the present application and a method for installing a heat insulation material 7 using the heat insulation material fixture. This heat insulation material fixture 1 is also configured by combining a heat insulation material hanging tool 2 attached to the heat insulation material 7 side and a beam fixture 3 attached to the beam member 8 side. Since the basic configuration is the same as that of the aforementioned first embodiment, the same reference numerals are given to the substantially identical components in the first embodiment, and detailed descriptions thereof are omitted, and the description will focus on the differences.

[0028] The heat insulation material hanging tool 2 of the second embodiment, similar to the first embodiment, includes a round bar-shaped hanging shaft portion 21, a flange-shaped latching portion 22 provided at one end thereof, and a hanging receiving portion 23 provided at the other end thereof. However, the hanging receiving portion 23 is formed in a large-diameter disc shape. The point that the hanging shaft portion 21 and the flange-shaped latching portion 22 are integrally formed and the hanging receiving portion 23 is formed as a separate body that can be retrofitted to the hanging shaft portion 21 is the same as that of the first embodiment.

[0029] The beam fixture 3 of the second embodiment also includes a beam fixing base portion 4 and a hanging attachment portion 5, similar to the first embodiment. However, it is different from the first embodiment in that the beam fixing base portion 4 and the hanging attachment portion 5 are formed as separate bodies.

[0030] At an intermediate portion near the clip portion 41 on one side of the beam fixing base portion 4, an engaging portion 45 is formed by punching out the beam fixing base portion 4 in a stepped and bent shape by the thickness of the joint base portion 51 of the hanging attachment portion 5 and opening a slit 44 on one side thereof. On the other hand, the joint base portion 51 of the hanging attachment portion 5 is formed longer than that of the first embodiment, and the hanging attachment portion 5 and the beam fixing base portion 4 are integrated by inserting the joint base portion 51 into the slit 44 and holding it on the engaging portion 45. The form of the hanging groove 55 formed in the hanging attachment portion 5 is the same as that of the first embodiment.

[0031] Thus, when the beam fixing base 4 and the hanging part 5 are formed separately, as shown in FIGS. 6 to 8, the heat insulating material hanger 2 attached to the heat insulating material 7 can be first hooked on the hanging groove 55 of the hanging part 5 and then lifted to the height of the beam member 8 and engaged with the beam fixing base 4 attached to the beam member 8. The engaging means between the separately formed beam fixing base 4 and the hanging part 5 is not limited to the exemplified form, and may be formed by appropriately combining cuts, concavities and convexities, grooves, etc.

[0032] FIG. 9 shows the heat insulating material fixture 1 according to the third embodiment of the invention disclosed in the present application. (a) is a side view, and (b) is a bottom view of the beam fixture 3. In this embodiment, the hanging receiving part 23 of the heat insulating material hanger 2 is formed in a shape such that a cylindrical body with a substantially octagonal cross section is cut in half in a plane including its axis, and the heat insulating material 7 is attached along its peripheral surface so as to support it. On the other hand, the beam fixture 3 has a clip-shaped beam fixing base 4 that sandwiches the lower flange 81 on one side of the beam member 8, and the beam fixing base 4 and the hanging part 5 are formed so as to be continuous with a single strip plate.

[0033] The hanging part 5 includes a hanging part 52 that extends downward short from the lower side part of the beam fixing base 4, a horizontal part 54 that extends substantially horizontally from the lower end edge of the hanging part 52 toward the indoor side, an inclined part 53 that extends gently upward and obliquely from the indoor side edge of the horizontal part 54 further toward the indoor side, and a second horizontal part 58 that extends short from the upper end edge of the inclined part 53 further toward the indoor side. And a hanging groove 55 for hanging the heat insulating material hanger 2 on the hanging part 5 extends from the opening end 56 formed at the edge of the second horizontal part, passes through the inclined part 53, and reaches near the middle of the horizontal part 54 and is formed to be refracted in a substantially L shape and reach the closed end (terminal) 57. Even in the form of hooking the heat insulating material hanger 2 on such a hanging groove 55, a hanging state in which the heat insulating material hanger 2 does not easily come out of the hanging groove 55 can be realized.

[0034] FIG. 10 shows a modified example of the hanging attachment part 5. This hanging attachment part 5 is simpler than the form in FIG. 9 and is composed of only two parts: a hanging part 52 that extends downward short from the clip-shaped beam fixing base 4, and an inclined part 53 that extends gently upward and obliquely from the lower end edge of the hanging part 52 toward the indoor side. A hanging groove 55 for hanging the heat insulation material hanger 2 on this hanging attachment part 5 is formed to extend from the open end 56 formed at the edge of the inclined part 53 in the direction of descending the inclined part 53 and to be refracted in a substantially L shape to reach the closed end (terminal end) 57. When the heat insulation material hanger 2 is hooked on such a hanging groove 55, the hanging shaft part 21 will be held with a slight inclination, but even in this form, a hanging state in which the heat insulation material hanger 2 does not easily come out of the hanging groove 55 can be realized.

[0035] Note that the forms of the hanging attachment part 5 and the hanging groove 55 can be variously deformed not only in the forms as exemplified but also within the range where the same hanging state as described above can be obtained. Basically, an appropriate height difference is provided in the hanging attachment part 5 by the inclined part 53 or the like, and if the closed end 57 of the hanging groove 55 is provided at a position lower than the open end 56 or the middle part, the heat insulation material hanger 2 will not return to the open end 56. Also, by providing appropriate bending parts or the like in the planar shape of the hanging groove 55, it is possible to prevent the heat insulation material hanger 2 from coming out even in a configuration with only flat parts without a height difference.

[0036] According to the heat insulation structure in which the heat insulation material 7 is suspended below the beam member 8 via the heat insulation material fixture 1 as described above, the flexible heat insulation material 7 having no self-supporting 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. 3) or the foamed resin molded body. The heat insulation material 7 to be suspended can be constructed in a size that can cover the height from the upper floor beam member 8 to the lower floor beam member (or a base or the like: not shown) with a single sheet, so the construction efficiency is good. Special techniques or tools are not required for the construction. Furthermore, the suspended heat insulation 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.

[0037] The upper edge 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 (the heat insulating material 7 at the location where the heat insulating material hanging tool 2 is not installed abuts against the beam member 8 without being compressed in the thickness direction), so that heat insulation deficiency or insufficient heat insulation is unlikely to occur below the beam member 8. Further, as shown in FIG. 4, if the vertical side edges 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.

[0038] In addition, this heat insulating material fixing tool 1 can also be attached to beam members other than H-shaped steel and other horizontal members similar to beam members (including wood, etc.). The "beam member" described in this specification and the claims includes such horizontal members. Since the form of the beam fixing base 4 may be appropriately changed according to the cross-sectional shape of the beam member, the fixing means to the beam member is not limited to that by the clip portions 41 and 42 as illustrated. For example, it can be engaged with round holes formed in the beam member, bolted and fastened, or fixed with screws or nails in the case of wood.

[0039] FIG. 11 shows a form in which a beam fixture 3 according to still another modification is attached to the side surface of a beam member 80 made of wood with a rectangular cross-section. The illustrated beam fixture 3 has a flat plate-shaped beam fixing base 4 that is screwed to one side surface of the beam member 80, and a hanging portion 5 is formed by folding the lower end portion of the beam fixing base 4 upward. The hanging groove 55 for hanging the heat insulating material hanging tool 2 is formed to extend downward from an open end 56 formed at the upper edge of the hanging portion 5 to a closed end (terminal end) 57. When the hanging shaft portion 21 of the heat insulating material hanging tool 2 is laterally hung on such a hanging groove 55, a hanging state in which the upper edge portion of the heat insulating material 7 does not bend can be realized.

[0040] 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 9 (see FIG. 3), the heat insulating material 7 can be easily separated from and held away from the outer wall material 9. Thus, a ventilation heat insulation structure for the outer peripheral portion having a ventilation space on the back side of the outer wall material 9 can be preferably realized, and condensation prevention inside the wall and optimization of the heat insulation efficiency can be achieved.

[0041] Note that the technical scope of the invention disclosed in this application should not be construed in a limited manner by the exemplified embodiments, but should be conceptually construed based on the description in the claims. The names of the components used in the claims and the specification are for convenience in facilitating a specific understanding of the invention, and such names do not unduly limit the concept and properties of the components.
