Description

  The present invention relates to a heat insulating panel made of a foamed resin heat insulating material incorporated in a ceiling of a building and a building using the heat insulating panel.

  Conventional heat insulating materials that are constructed on the roof beams or on the roof beams and eaves girder, that is, on the back of the ceiling, have been used in which fibers are wrapped with a synthetic resin sheet. The reason why such a heat insulating material made of foamed resin is not often used on the back of the ceiling is that the rafters obstruct the plate-shaped construction. As a thing which solved the problem of interference of this rafter and made it possible to construct a plate-like heat insulating material, there is one in which a mark for making a cut is provided in a portion corresponding to the rafter (see Patent Document 1).

The width of the formation region of the concave groove 13a at the corner portion for the rafter 6 is about half of the width of the formation region of the concave groove 13b at the center portion.

  The concave grooves 13a and 13b for the rafter 6 are formed at locations overlapping the concave grooves 12a and 12b for the shed bundle 4.

  3A and 3B are a plan view and a sectional view showing the concave grooves 12b and 12c for the shed bundle 4, respectively. As shown in FIG. 3 (B), the heat insulating panel 7 is made of a foamed resin heat insulating material, embedded in the reinforcing material 9 (see FIG. 7), thinner than the first layer 14 and the first layer 14, The second layer 15 is fixed to the layer 14 by adhesion or the like. The second layer 15 is slightly wider than the first layer 14, and the periphery of the second layer 15 slightly protrudes from the periphery of the first layer 14 (a = 1 to 3 mm (see FIG. 3B)). To be fixed. The concave grooves 12b and 12c are composed of one U-shaped groove 16 and L-shaped grooves 17 on both sides thereof so that it can be cut into the shape of a half of a pillar as a whole. These grooves 16 and 17 are formed in a penetrating structure with respect to the first layer 14, and the second layer 15 is formed in a concave shape from the surface toward the inside. In addition, each of the grooves 16 and 17 has enlarged portions 16a and 17a on the opening, that is, on the surface layer side so that a finger can be inserted.

The concave groove 12 a for the shed bundle 4 is composed of two L-shaped grooves 17 and 18, and these grooves 17 and 18 are formed at the same positions of the first layer 14 and the second layer 15. Of these grooves 17 and 18, those on the first layer 14 side have enlarged portions 17 a and 18 a into which fingers can be inserted, respectively. The concave groove 13a for the rafter 6 is formed only in the first layer 14, and is formed by continuously forming a plurality of L-shaped grooves 19a to 19f having different depths (increase gradually). Due to the presence of the groove 18 of the concave groove 12 a, the groove 18 is used as a part of the concave groove 13 a for the rafter 6. Enlarged portions 19x into which fingers can be inserted are formed in the openings of the L-shaped grooves 19a to 19f.

  5A and 5B are a plan view and a cross-sectional view of the concave grooves 12b and 13b at the center of the end portion in the longitudinal direction of the heat insulating panel 7. FIG. As in the case of FIGS. 3A and 3B, the concave groove 12b for the shed bundle 4 can be cut into the shape of a half of the column as a whole, and a single U-shaped groove 16 and L on both sides thereof are formed. It consists of a letter-shaped groove 17. The concave groove 13b for the rafter 6 is formed only in the first layer 14, and is formed by continuously forming a plurality of U-shaped grooves 20a to 20f having different depths (increase in depth). Due to the presence of the groove 16 of the concave groove 12b, the groove 16 is used as a part of the concave groove 13b for the rafter 6. Enlarged portions 20x into which fingers can be inserted are also formed in the openings of the U-shaped grooves 20a to 20f.

  FIG. 6 is a plan view showing a state in which the heat insulating panel 7 is installed on the shed beam 3 surrounded by the shed bundle 4. When attaching the heat insulating panel 7, by removing the portions where the concave grooves 12 a to 12 c of the heat insulating panel 7 corresponding to the shed bundle 4 are formed by using a knife, a driver or a finger, the cutout portion 27 generated by the removal is formed in the shed bundle 4. As shown in FIGS. 7 and 8, the heat insulating panel 7 is fixed to the roof beam 3 by inserting a fixing tool 21 such as a screw or a nail through the hole 10 of the reinforcing member 9.

It becomes possible to maintain heat insulation over a long period of time.

  Further, as shown in FIGS. 9 and 10, the space between the two reinforcing members 9 and 9 is formed so that the inspection window 22 can be inserted. Therefore, as shown in FIGS. The inspection window 22 can be attached by incising (23) the portion between the reinforcing members 9 and 9 into a width enough for the inspection window 22 to enter. In this example, the inspection window 22 has a foamed resin heat insulating material 22a attached to the frame 22b. The heat insulating material 22a is fitted into the cut-out opening 23 of the heat insulating panel 7, and a nail, a screw, or the like is attached to the frame 22b. It is attached by fixing to the reinforcing material 9 with the fixture 24. The frame 22b may be fixed to the roof beam 3.

  Moreover, in this Embodiment, since the 2nd layer 15 is formed a little wider than the 1st layer 14 of the heat insulation panel 7, as shown in FIG. 11, the heat insulation panels 7 mutually faced are 2nd. The layers 15 are arranged in pressure contact with each other. For this reason, when constructing the heat insulation panel 7, it is possible to arrange the heat insulation panels 7 by pressing the thin and easily deformable second layers 15, and the construction is facilitated, and the gap between the heat insulation panels 7 and 7 is reduced. Occurrence can be prevented.

  FIGS. 12 and 13 are a side view and a plan view showing the case where the heat insulation panel 7 is installed by placing one end of the heat insulation panel 7 on the eaves girder 2 where the rafter 6 is present. In this case, the recessed grooves 13a and 13b formed at the end of the heat insulating panel 7 and the enlarged portions 16a and 18a of the U-shaped grooves 16 and 18 which are part of the recessed grooves 12a and 12b for the shed bundle 4 are indicated. Are removed at the corners to form a cut portion 25 inclined at the corner and a cut portion 26 inclined at the center, and these cut portions 25 and 26 are fitted into the rafter 6 so that the heat insulating panel 7 is placed on the roof beam 3. Install. The other concave grooves 12a to 12c corresponding to the portion corresponding to the shed bundle 4 of the heat insulating panel 7 are similarly cut out and fitted into the shed bundle 4.

  Thus, in this Embodiment, since the recessed groove | channels 12a-12c for forming the cutting part which avoids the shed bundle 4 were provided in the peripheral part of the heat insulation panel 7, this recessed shape interfered with the shed bundle 4 By cutting the grooves 12a to 12c, the cut portion can be fitted into the shed bundle 4 for construction. Moreover, since the concave grooves 13a and 13b for forming the cut-out portion that avoids the rafter 6 are provided so as to overlap the concave grooves 12a and 12b provided in the concave portion formation for the shed bundle 4, the construction in which the rafter 6 interferes. This heat insulation panel 7 can be used also for the construction location where the location and the shed bundle 4 interfere.

  Further, the mark indicating the region to be cut may be a simple mark by printing or the like, but by using the concave grooves 12a to 12c, 13a, and 13b as this mark, this part is cut with a knife or the like along the concave groove. Thus, the shape of the rafter 6 and the shed bundle 4 can be easily cut.

  In the present embodiment, since at least the openings of the concave grooves 12a to 12c, 13a, and 13b are formed in a size that allows insertion of the finger, the concave shape is formed by inserting the finger into the concave grooves 12a to 12c, 13a, and 13b. By removing the portion surrounded by the groove, it is possible to easily form a portion corresponding to a rafter or a shed bundle without using a tool such as a knife.

  Further, in this embodiment, the concave grooves 13a and 13b formed in the portion corresponding to the rafter 6 are formed by continuously forming a plurality of concave grooves 19a to 19f or 20a to 20f having different depths. Since the portions other than the portions where the concave grooves 19a to 19f or 20a to 20f are formed remain in the portions other than the portion where the rafter 6 is to be constructed, the construction can be performed while maintaining a certain degree of strength and heat insulation performance.
