Description

  The present invention relates to a support bracket for supporting a panel between support members arranged side by side at a predetermined interval, and more particularly, to support a heat insulating material between rafters for a roof of a building. The present invention relates to a support metal fitting suitable for use.

  In recent years, buildings such as wooden houses have adopted a heat insulating structure throughout the building in order to ensure a living environment having a comfortable temperature and humidity and to save energy used for air conditioning. In such a heat insulating structure, heat insulation is spread between floor beams as support members arranged at predetermined intervals on the floor of the building, and supports arranged at predetermined intervals on the roof of the building. Thermal insulation is spread between rafters as members. A substantially Z-shaped metal fitting formed by bending a thin steel plate at a right angle is used to fix the spread heat insulating material. When a substantially Z-shaped metal fitting is applied to the floor, one end thereof is fixed to the upper surface of the floor beam, and the lower end of the heat insulating material is supported by the other end.

  Since the Z-shaped metal fitting has a low strength and is easily detached from the support member, for example, an improvement technique of the support metal fitting disclosed in Patent Document 1 is often used. That is, as shown in FIG. 13, the support metal fitting 200 has a mounting portion 210 having a U-shaped cross section having a top surface portion 211 and side surface portions 212 extending vertically from both edges of the top surface portion 211. It has. A support portion 220 extends at the edge of the attachment portion 210 so as to be substantially orthogonal to the side surface portion 212. A claw portion 213 protruding downward is formed on the lower surface of the top surface portion 211. A claw portion 221 that protrudes upward is formed on the upper surface of the support portion 220. When the support metal fitting 200 is used for supporting a heat insulating material for a floor, the attachment portion 210 is attached so as to straddle the floor beam, and the support portion 220 supports the lower end portion of the heat insulating material. In such a support metal 200, the attachment part 210 is fixed to the floor beam by piercing the claw part 213 into the upper surface of the floor beam, and the support metal part 200 is pierced into the lower surface of the heat insulating material. The heat insulating material is fixed to the floor beam.

JP-A-6-57932 (summary)

  However, since the support metal fitting 200 as described above is configured as a heat insulating material support means for a floor, there are the following problems when used as a heat insulating material support means for a roof. The roof is a place where the wind is easy to hit. Therefore, when the heat insulating material is spread between the rafters, when the heat insulating material is fixed by inserting the claw portion 221 into only the lower surface of the heat insulating material as in the case of the supporting metal 200, the heat insulating material is supported by the metal fitting when the wind blows from under the roof. There was a risk that it would float from 200 and eventually detach from it. In addition, when the heat insulating material is spread between the rafters, when the support member 200 is fixed to the rafters by piercing only the upper surface of the rafters as in the case of the supporting metal 200, the wind blows from under the roof, and the heat insulating material When a force is applied to the upper side, the force is also applied to the support fitting 200 fixing the heat insulating material, and the claw portion 213 may come off the rafter. In particular, since a lightweight heat insulating material made of a plastic foam has been used in recent years, the above problem has been likely to occur. Furthermore, in the case of a roof, since the rafters are inclined downward, when the heat insulating material is supported by the rafters via the support fitting 200, the heat insulating material is also inclined downward along the rafters. For this reason, since the nail | claw part 213 is easy to remove | deviate from the upper surface of a rafter as mentioned above, when force was applied to the support metal fitting 200 in the inclination direction lower side of the rafter, the support metal fitting 200 might slide down together with the heat insulating material. .

  On the other hand, the heat insulating material fixed between the rafters as described above is arranged so that the upper surface thereof is in contact with the roofing material or the roof base portion, and the lower surface is the indoor side, and between the upper and lower surfaces of these heat insulating materials, Since it is insulated by the heat insulating material, a temperature difference is generated. However, when the temperature difference becomes large, the support bracket 200 as described above is made of metal, so the thermal conductivity is large and the area of the side surface portion 212 is large. Condensation had occurred.

  Therefore, even when the present invention is applied as a heat insulating material support means for a roof, an object of the present invention is to provide a support metal fitting that can stably support the heat insulating material and prevent the occurrence of condensation. .

  The support bracket of the present invention is a support bracket for supporting a panel such as a plate-like heat insulating material between support members arranged side by side at a predetermined interval. A side surface portion formed on the surface portion, having a U-shaped cross section, and being fixed so as to straddle the support member, and extending from the edge of the side surface portion substantially orthogonally toward the outside. And a support portion fixed to the lower surface of the panel, such as a plate-like heat insulating material, and a first claw portion protruding downward is formed on the top surface portion, and a first protrusion protruding upward is formed on the support portion. By forming two claw portions, forming a third claw portion having a claw bent at the tip in the vicinity of the side surface portion of the top surface portion, and projecting the first claw portion into the upper surface of the support member, The mounting portion is fixed to the support member, the second claw portion is pierced into the lower surface of the panel such as a plate-like heat insulating material, and the third claw portion is folded. Bending by piercing the pawl on the upper surface of the panel such as a plate-like heat insulating material, is characterized in that a panel such as a plate-like insulation material is secured to the support portion.

  In the support metal fitting of the present invention, the first claw portion protruding downward is formed on the top surface portion. Therefore, when applied as a heat insulating material support means for roof, the first claw portion is a rafter as a support member. The attachment portion can be fixed to the rafter by piercing the upper surface of the ridge. In addition, a second claw portion protruding upward is formed on the support portion, and a third claw portion having a claw bent at the tip is formed to protrude outward in the vicinity of the side surface portion of the top surface portion. Therefore, it is possible to squeeze the heat insulating material from above and below by piercing the second nail portion into the lower surface of the plate-like heat insulating material as a panel and bending the third nail portion and piercing the nail into the upper surface of the heat insulating material. it can. Thereby, since it is possible to exert a strong holding force against the vertical force acting on the heat insulating material, the heat insulating material can be stably fixed to the support fitting. Therefore, since the load of the heat insulating material generated toward the lower side in the inclination direction of the rafter can be supported, the heat insulating material can be stably supported, and the configuration is simple. Furthermore, since the heat insulating material can be sandwiched and pressed from above and below as described above, even if the wind blows from below during construction and a force acts on the heat insulating material, the heat insulating material rises or wind It can be prevented from being blown by and it is safe.

  Here, when applying a support metal fitting as a heat insulating material support means for roofs as mentioned above, various techniques can be used in order to improve the support performance. For example, the fourth claw portion can be formed on the side surface portion so as to protrude inward. In such an aspect, when the fourth claw portion is pierced into the side surface of the rafter, the pierced fourth claw portion is caught by the rafter fiber, so that the support metal fittings are provided on both sides of the rafter surface and the rafter. Since it can be fixed at three points on the claw portion of the surface, it is possible to exert a strong holding force against the forces in the vertical and horizontal directions. As a result, the heat insulating material can be firmly fixed to the rafters via the support bracket, so that even if wind blows from below during construction and the force acts on the heat insulating material, the heat insulating material will rise It can be further prevented from being blown by the wind, and is safer.

  Moreover, the support metal fitting can be provided with a means for preventing the occurrence of condensation due to the high thermal conductivity of the metal and the temperature difference generated between the upper and lower surfaces of the heat insulating material. For example, a heat conduction suppressing portion for suppressing heat conduction from the upper end portion of the side surface portion to the lower end portion can be formed on the side surface portion. In such an aspect, when a heat insulating material is used for the roof, a large temperature difference occurs between the upper and lower surfaces, but since the heat conduction suppressing portion is formed on the side surface portion, the side surface is formed by the heat conduction suppressing portion. The heat conduction from the upper end to the lower end of the part can be suppressed. Therefore, the thermal bridge phenomenon at the side surface portion can be suppressed, so that the occurrence of condensation can be prevented.

  Specifically, the heat conduction suppression unit can be realized by reducing the heat conduction speed and heat capacity in the side surface part. For example, a gap for blocking heat conduction from the upper end portion to the lower end portion may be formed in the side surface portion, and the upper side surface portion and the lower side surface portion separated by the gap may be connected by a heat insulating member. it can. A heat conduction suppressing part can be constituted by these gaps and the heat insulating member. In such an aspect, the heat conduction from the upper end portion to the lower end portion of the side surface portion can be further suppressed by the gap and the heat insulating member.

  Moreover, while connecting the upper end part and lower end part of a side part as a heat conduction suppression part, the connection part which has a width | variety smaller than the upper end part and lower end part of a side part can be formed. For example, by forming an opening in the central part of the side part, the connecting part can be configured to connect to both side edges of the upper end part and the lower end part of the side part. Or the said connection part can be comprised so that it may connect with each center part of the upper end part of a side part, and a lower end part by forming a notch in the both-sides edge part of the center part of a side part. It is desirable for the connecting portion to increase the area of the opening or the cutout as much as possible within a range that satisfies the strength required for the support fitting. In such an aspect, since the heat conduction area of the part between the upper end part and lower end part of a side part can be made small, the heat conduction from the upper end part of a side part to a lower end part can further be suppressed. .

(1) Configuration of Embodiment Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a view showing a support metal fitting according to an embodiment of the present invention, in which (A) is a front view, (B) is a side sectional view, and (C) is a top view.

A claw part (third claw part) 16 is bent and formed at the end of the opening 15 on the top surface part 11 side so as to protrude vertically upward. The claw portion 16 is formed by bending a triangular claw 16a at its tip, and has an inverted L-shaped cross section.

  The side surface portion 12 of the mounting portion 10 has an upper side surface portion 12A and a lower side surface portion 12B, and a gap 12C having a predetermined length is formed between the upper side surface portion 12A and the lower side surface portion 12B. ing.

The heat conduction suppression unit 30 has a claw 31 formed on the upper side surface portion 12A and a claw 32 formed on the lower side surface portion 12B, and the claw 31, 32 allows the upper side surface portion 12A and the lower side surface portion 12B to A heat insulating member 33 for connecting the two is fixed. The heat insulation member 33 is made of a resin such as plastic having heat insulation.

(2) Installation method of embodiment Next, the suitable installation method of the support metal fitting of this embodiment is demonstrated with reference to FIG. FIG. 2 is a schematic perspective view showing a state in which the support fitting of the present embodiment is fixed to a rafter as a support member arranged in a lateral direction with a predetermined interval on the roof, and FIG. It is a schematic sectional drawing showing the state by which the heat insulating material as a panel is supported by the support metal fitting fixed to the rafter of FIG. 2 and 3, only one rafter is shown, and the front side of the page is the lower side of the roof. In FIG. 3, only the heat insulating material adjacent to one rafter of FIG. 2 is shown.

  First, as shown in FIG. 2, the support metal fitting 1 of this embodiment is fixed to the rafter 101 (support member). That is, the support fitting 1 is attached so that the attachment portion 10 straddles the rafter 101. In this case, the nail | claw part 14 is stabbed into the upper surface of the rafter 101 by hitting the nail | claw part 14 from the upper side of the opening 13 of the top surface part 11 of the attaching part 10 using a hammer etc., as shown in FIG. At this time, the support metal fitting 1 is attached so that the both side surface portions 12 are slightly expanded outward and the rafter 101 is sandwiched. When the plate-shaped heat insulating material 102 is spread between the rafters 101 as described below, the support metal fitting 1 is spread. The both side surfaces 12 of the support fitting 1 are pressed against the rafter 101 by the plate-shaped heat insulating material 102 thus formed. Thereby, the nail | claw part 18 pierces the both sides of the rafter 101 naturally, and is hooked on the fiber peculiar to wood, Therefore A strong holding force with respect to the force of an up-down direction is exhibited. Thus, the support fitting 1 is stably fixed at three points on both the side surface and the upper surface of the rafter 101 by the claw portion 14 pierced on the upper surface of the rafter 101 and the claw portion 18 pierced on both side surfaces of the rafter 101. .

  Subsequently, a plate-like heat insulating material 102 (panel) is spread between adjacent rafters 101, and the heat insulating material 102 is fixed between the rafters 101 by the support fitting 1 fixed to the rafter 101 as shown in FIG. To do. That is, the end portion of the heat insulating material 102 is placed on the upper surface of the support portion 20 of the support fitting 1. In this case, the nail | claw part 22 is arrange | positioned so that it may expand toward the direction of the up-slope of the rafter 101 arrange | positioned with a gradient in the upper surface of the support part 20. As shown in FIG. Next, the nail | claw part 22 is pierced by the lower surface of the heat insulating material 102 by hand, as shown in FIG. 3, pressing down the upper surface of the heat insulating material 102 mounted. Next, the nail portion 16 of the top surface portion 11 is bent by approximately 90 degrees with a finger, and the nail 16a of the nail portion 16 is pierced into the upper surface of the heat insulating material 102 as shown in FIG. Since the upper and lower surfaces of the heat insulating material 102 are sandwiched by the claw portions 16 and 22 pierced on the upper and lower surfaces of the heat insulating material 102 in this way, the heat insulating material 102 is stably supported.

  In the support metal fitting 1 of this embodiment, since the claw part 13 which protrudes below is formed in the top surface part 11, when it applies as a heat insulating material support means for roofs, the claw part 13 is used as a support member. The attachment portion 10 can be fixed to the rafter 101 by piercing the upper surface of the rafter 101. Further, a claw portion 22 that protrudes upward is formed on the support portion 20, and a claw portion 16 that has a claw 16 a bent at the tip is protruded outward in the vicinity of the side surface portion 12 of the top surface portion 11. Since the claw portion 22 is pierced into the lower surface of the heat insulating material 102 as a panel and the claw portion 16 is bent and the claw 16a is pierced into the upper surface of the heat insulating material 102, the heat insulating material 102 is sandwiched and pressed from above and below. be able to. Accordingly, a strong holding force can be exerted against the vertical force acting on the heat insulating material 102, and the heat insulating material 102 can be stably fixed to the support fitting 1. Therefore, since the load of the heat insulating material 102 generated toward the lower side in the inclination direction of the rafter 102 can be supported, the heat insulating material 102 can be stably supported, and the configuration is simple. Furthermore, since the heat insulating material 102 can be sandwiched and pressed from above and below as described above, even if a wind blows from below during construction and a force acts on the heat insulating material 102, the heat insulating material 102 rises. Can be prevented from being blown by the wind, and is safe.

  In particular, in this embodiment, when the nail portion 18 is pierced into the side surface of the rafter 101, the pierced nail portion 18 is caught by the fibers of the rafter 101. Therefore, the support fitting 1 has the nail portion 14 on the surface of the rafter 101. And since it is fixed at three points of the claw portions 18 on both sides of the rafter 101, it is possible to exert a strong holding force against the force in the vertical and horizontal directions. Thereby, since the heat insulating material 102 can be firmly fixed to the rafter 101 through the support fitting 1, even if wind blows from below during construction and a force acts on the heat insulating material 102, the heat insulating material It is possible to further prevent the 102 from rising or being blown by the wind, and it is further safer.

  Moreover, when the heat insulating material 102 is used for the roof, a large temperature difference occurs between the upper and lower surfaces thereof, but since the heat conduction suppressing portion 30 is formed on the side surface portion 12, the heat conduction suppressing portion 30 forms the side surface. Heat conduction from the upper end portion of the portion 12 to the lower end portion can be suppressed. Therefore, since the thermal bridge phenomenon at the side surface portion 12 can be suppressed, the occurrence of condensation can be prevented. In particular, since the heat conduction suppressing portion 30 is configured by the gap 12C and the heat insulating member 33, heat conduction from the upper end portion to the lower end portion of the side surface portion 12 can be further suppressed.

(3) Modifications Although the present invention has been described with reference to the present embodiment, the present invention is not limited to the present embodiment, and various modifications can be made. For example, the support fitting 1 is used to support the heat insulating material 102 between the rafters 101 arranged at a predetermined interval on the roof, but is not limited thereto, and is inclined in the vertical direction and in the horizontal direction. Between the support members arranged side by side, the support fitting 1 may be used to support various panels as well as the heat insulating material. Further, as in the case where the heat insulating material is supported between the floor beams, the support bracket 1 is used to support various panels as well as the heat insulating material between the support members arranged horizontally in the horizontal direction. May be used.

  In the present embodiment, instead of providing the gap 12C and the heat insulating member 33 as the heat conduction suppressing portion 30, the upper end portion and the lower end portion of the side surface portion 12 are connected and the upper end portion and the lower end portion of the side surface portion 12 are connected. A connecting portion having a smaller width can be provided. For example, in the support fitting 2 as shown in FIG. 4, a rectangular opening 34 is formed at the center of the side surface portion 12, and a connecting portion 35 is formed so as to sandwich the opening 34. The connecting portion 35 is connected to both side edge portions of the upper end portion and the lower end portion of the side surface portion 12. Such a support fitting 2 can be fixed to the rafter 101 and can support the heat insulating material 102 as shown in FIGS. 5 and 6 by the same method as the support fitting 1 described above. In such an aspect, since the heat conduction area of the side surface portion 12 can be reduced by the connecting portion 35 formed in the intermediate portion of the side surface portion 12, the heat conduction from the upper end portion to the lower end portion of the side surface portion 12 can be reduced. Further suppression can be achieved.

  Further, in the support fitting 3 as shown in FIG. 7, rectangular cutouts 36 are formed at both side ends of the central portion of the side surface portion 12, and a connecting portion 37 is formed between the cutouts 36. The connecting portion 37 is connected to the central portion of each of the upper end portion and the lower end portion of the side surface portion 12. Such a support fitting 3 can be fixed to the rafter 101 and can support the heat insulating material 102 as shown in FIGS. 8 and 9 by the same method as the support fitting 1 described above. In such an aspect, since the heat conduction area of the side surface portion 12 can be reduced by the connecting portion 37 formed in the middle portion of the side surface portion 12, heat conduction from the upper end portion to the lower end portion of the side surface portion 12 can be reduced. Further suppression can be achieved.

  In addition, in this embodiment, it can comprise, without providing the heat conduction suppression part 30 in the side part 12, like the support metal fitting 4 shown in FIG. As shown in FIGS. 11 and 12, the support bracket 4 can be fixed to the rafter 101 and can support the heat insulating material 102 by being installed in the same manner as the support bracket 1 described above.

(Insulation performance test)
Examples of the present invention will be described. In this example, the test body provided with the support metal fittings of Examples 1 to 4 was attached to the door portion of the electric drying furnace, and the inside of the furnace was set at a predetermined temperature (Examples 1 to 4 were 60 ° C. 6 was heated to 80 ° C.), and the temperatures of the support surface on the heating surface side and the surface side (opposite the heating surface) were measured. The measurement was performed for about 1 hour every 30 seconds from the start of heating, and was finished when the temperature on the surface side became almost constant. The test body was configured as shown in FIG. 3 or FIG. 6, cedar was used as a rafter, a heat insulating panel made of a plastic foam was used as a heat insulating material, and various samples were used as the support fitting of the present invention. The measurement results of Examples 1 to 4 are shown in Table 1. The surface side of the support metal fitting is set to room temperature.

  Example 1 is a 49H plastic joint type support fitting as a sample of the support fitting 1 of the embodiment. Example 2 is a 34H plastic joint type support fitting as a sample of the support fitting 1 of the embodiment. Example 3 is a 49H central opening type support metal fitting as a sample of the support metal fitting 2 of the embodiment. Example 4 is a 34H center opening type support metal fitting as a sample of the support metal fitting 2 of the embodiment. The heights of the side surfaces of the samples of Examples 1 and 2 are 49 mm and 34 mm, respectively. The width of the side part of the samples of Examples 1 and 2 is 18 mm. The space | interval of the clearance gap of the side part of the sample of Example 1, 2 is 2 mm. The heights of the side surfaces of the samples of Examples 3 and 4 are 49 mm and 34 mm, respectively. The width of the side part of the samples of Examples 3 and 4 is 18 mm. The size of the opening at the center of the samples of Examples 3 and 4 is 20 mm long and 14 mm wide. The sample of Example 5 is the same support bracket as that of Example 1, and the sample of Example 6 is the same support bracket as that of Example 3.

  As can be seen from Table 1, in the 49H plastic joint type support metal fitting of Example 1, the surface temperature on the side opposite to the heating surface was 42.4 ° C., even though the temperature on the heating surface side was 59.7 ° C. Thus, a large temperature difference of 17.3 ° C. was obtained. Thereby, in the support metal fitting 1 of embodiment of this invention, it was shown that a big heat conduction inhibitory effect can be acquired. Further, in the 49H central opening type support metal fitting of Example 3, the surface side temperature opposite to the heating surface was 44.8 ° C. despite the heating surface side temperature of 58.6 ° C. A large temperature difference of 8 ° C. was obtained. Thereby, it was shown that the support metal fitting 2 of embodiment of this invention can also acquire the big heat conduction inhibitory effect.

  In addition, from the comparison between Example 1 and Example 2 and the comparison between Example 3 and Example 4, the support metal fitting of the present invention can obtain a greater effect of suppressing heat conduction when the side portion has a larger height. I found that I can do it.

  Further, based on a comparison between Example 1 and Example 5 and a comparison between Example 3 and Example 6, the support metal fitting of the present invention is exposed to a temperature at which the surface opposite to the room temperature side has a larger temperature difference from the room temperature. It has been found that a greater effect of suppressing heat conduction can be obtained.

  As described above, it has been proved that the support metal fitting of the present invention has an excellent heat conduction suppressing effect.
