Embodiments of the present invention will be described below with reference to the accompanying drawings.
As shown in FIG. 1, in the structure of the roof of the building of this embodiment, a plurality of bundles 2 having a height corresponding to the water gradient of the roof are attached on the plurality of shed beams 1. Yes. The roof is, for example, a flat roof, and the water gradient is, for example, 1/100 or more and 1/30 or less. The shed beam 1 is made of, for example, H-shaped steel, and is horizontally fixed to an upper end portion of a column (not shown). For example, corners of four roof panels 3 adjacent to each other on the top, bottom, left, and right are placed on the bundle 2. In the building, the module width, which is the basic dimension of the design, is P, and the arrangement pitch of the bundle 2 is, for example, 2P at the maximum. When the module width P is a scale module, P = 910 mm, so 2P is 1820 mm.

  As shown in FIG. 2, the bundle 2 includes a base plate 21, a support column portion 22, a deposit plate portion 23, and a rising plate portion 24. In addition, it can be set as the structure which does not provide the said support | pillar part 22 in order to make the height of the bundle material arrange | positioned at the most underwater side of a roof as low as possible.

  The base plate 21 is a rectangular plate that is fixed to the roof beam 1, and the square side is provided substantially flush with the edge of the upper flange of the H-shaped steel that is the roof beam 1. Yes. Further, bolt insertion holes 21 a are formed at four corners of the base plate 21. A bolt insertion hole is formed in the upper flange of the shed beam 1 in accordance with the fixed arrangement of the bundle material 2, and the bolt insertion hole 21 a of the base plate 21 is aligned and inserted into the bolt insertion hole. By attaching a nut to a screw portion of a bolt 11 (see FIG. 4 and the like) and fastening it, the bundle 2 can be fixed to the shed beam 1.

  The support column 22 has a rectangular tube shape with a substantially square cross section, and is fixed to the base plate 21 by welding or the like. By changing the height of the support column 22, the height of the bundle 2 can be changed. In addition, the square side of the support column 22 is positioned non-parallel to the square side of the base plate 21, for example, 45 degrees around the axis of the support column 22. A location between the corner of the plate 21 and the side of the support column 22 is a fixed location (a location where the bolt insertion hole 21a is formed). For this reason, a position as close as possible to the center side of the base plate 21 can be set as a fixed portion. For example, when the roof beam 1 is made of H-section steel, the bundle material is positioned as close as possible to the web portion. 2 can be fixed.

  The deposit plate portion 23 faces the base plate 21 in parallel, and is fixed to the upper end portion of the support column portion 22 by welding or the like. The deposit plate portion 23 has a square shape and is provided so that each side is parallel to each side of the base plate 21. The roof panel 3 can be temporarily placed on the deposit plate portion 23 when the roof panel 3 is fixed to the rising plate portion 24.

  The upright plate portion 24 is disposed on the deposit plate portion 23 so as to be perpendicular to the deposit plate portion 23 and parallel to the water gradient direction of the roof, and is fixed to the deposit plate portion 23 by welding or the like. Has been. In the rising plate portion 24, a first insertion hole 24a through which a bolt 5 (see FIG. 4 and the like) as a fixing member for fixing the water upper side of the roof panel 3 located on the water lower side is inserted from the lateral direction; A second insertion hole 24b is formed through which the bolt 5 for fixing the underwater side of the roof panel 3 located on the upper side of the water is inserted from the lateral direction.

  In addition, in the bundle material 2 arrange | positioned at the keraba side of a roof, you may make it provide the said board part 23 and the standing board part 24 in the indoor direction with respect to the base board 21 or support | pillar part. . Moreover, in the bundle material 2 arrange | positioned at this keraba side, two roof panels 3 on the upper and lower sides are supported instead of four roofs on the upper and lower sides and right and left.

  The gradient of the line connecting the center of the first insertion hole 24a and the center of the second insertion hole 24b is larger than the water gradient of the roof. That is, with respect to the distance from the center of the first insertion hole 24a to the upper surface of the deposit plate portion 23 (base plate 21), the distance from the center of the second insertion hole 24b to the upper surface of the deposit plate portion 23 (base plate 21). The distance is increased in accordance with the water gradient, but is further increased. For example, the water gradient is 10/910, the horizontal distance from the center of the first insertion hole 24a to the center of the second insertion hole 24b is 91 mm, and the upper surface of the deposit plate portion 23 from the center of the first insertion hole 24a. The distance from the center of the second insertion hole 24b to the upper surface of the deposit plate portion 23 is 35 mm. In order to match the water gradient, it is sufficient to set the distance from the center of the second insertion hole 24b to the deposit plate portion 23 to 33 mm, but the distance is increased by about 2 mm. The 2 mm to be added is set in consideration of the clearances of the first and second insertion holes 24a and 24b, but is not necessarily limited to the clearance value. The horizontal distance from the center of the first insertion hole 24a to the center of the second insertion hole 24b is 91 mm, and the center of the first and second insertion holes 24a and 24b to the upper surface of the deposit plate portion 23. The above-mentioned distances of 32 mm and 35 mm are examples and are not limited to these. Further, the water gradient is not limited to the above 10/910.

  Further, the distance from the center of the first insertion hole 24a to the upper surface of the deposit plate portion 23 is such that the roof panel 3 is fixed when the roof panel 3 is fixed to the bundle 2 using the first insertion hole 24a. Is a distance that slightly floats from the deposit plate portion 23.

  Further, a notch 24c is formed in a corner portion on the water side of the upper side portion of the upright plate portion 24. The notch 24c is a mark indicating that the bundle 2 is arranged with the notch 24c under water. The mark indicating the arrangement direction of the bundle 2 is not limited to the notch, and may be a mark such as a figure, a character, a hole, a concave portion, or a convex portion. In a bundling material for a flat roof with a small water gradient, it is difficult to determine which side of the first and second insertion holes 24a, 24b is at a higher position, but by providing the mark, the bundling material 2 It is possible to prevent mistakes in the installation direction.

  As shown in FIGS. 3 (A), 3 (B), and 3 (C), the roof panel 3 is provided with a base plate 32 serving as a roof base on the upper side surface of the frame 31. In addition, the rafter 33 (refer FIG. 4) may be provided in the said roof panel 3, and also asphalt roofing may be provided as a secondary waterproof layer, for example. The frame 31 is formed in a rectangular frame shape, and a pair of first frame portions 31a disposed in parallel to the direction of the water gradient, and a pair of second frames disposed to intersect the first frame portion 31a. Part 31b.

  As shown in FIGS. 4 and 5, the first frame portion 31 a and the second frame portion 31 b are made of channel steel, and are provided so that the opening faces inward and the web portion faces outside. Bolt insertion holes are formed in the web portion of the first frame portion 31a. Bolts 5 that are respectively passed through the first insertion hole 24a and the second insertion hole 24b in the bundle 2 are inserted into the bolt insertion holes. For example, the bolt 5 is passed through the bolt insertion hole of one roof panel 3 in the two roof panels 3 adjacent to the left and right, the bolt 5 is further passed through the first insertion hole 24a, and the screw portion is passed through the other roof panel. 3 and can be tightened by screwing a nut 6 into the screw portion.

  If it is said structure, the corner | angular part of the several roof panel 3 which adjoins will be the said standing board part by the volt | bolt 5 each penetrated from the horizontal direction to the said 1st insertion hole 24a and the 2nd insertion hole 24b, respectively. Therefore, the roof panel 3 can be installed more efficiently than the structure in which the upper side and the lower side of the roof panel are fastened as in Patent Document 1 shown in the conventional section. Further, since the first frame portion 31a of the roof panel 3 is fixed to the bundle member 2, there is no need to additionally provide grooved steel or L-shaped steel on the roof panel as in Patent Document 1, and the roof The panel does not have a vertical orientation. In this way, by eliminating the need to provide additional groove steel or L-shaped steel on the roof panel, the cost of the roof panel 3 can be reduced, and the roof panel 3 can be prevented from being vertically oriented. The installation work of 3 becomes efficient.

  If the slope of the line connecting the center of the first insertion hole 24a and the center of the second insertion hole 24b is larger than the water gradient of the roof, the clearance between the first and second insertion holes 24a, 24b Due to the above, it is possible to prevent the water side of the above-mentioned roof panel on the lower side from becoming higher than the water side of the roof panel on the above water side. That is, for the clearance, the water side of the underwater roof panel 3 is fixed at the uppermost position of the first insertion hole 24a, and the water side of the waterside roof panel 3 is the second side. Even if it is fixed at the lowest position of the insertion hole 24b, the water side of the above-mentioned roof panel 3 on the water side is prevented from becoming higher than the water side of the roof panel 3 on the water side. be able to.

  Even if there is a step between the water side of the above-mentioned roof panel 3 on the water side and the water side of the above-mentioned roof panel 3 on the water side, a steel roof plate or the like serving as a primary waterproof layer is laid, There is no sexual problem. Moreover, since the asphalt roofing which is a secondary waterproof layer, for example, can be arranged so as to straddle the step portion, the waterproofness of the step portion can be sufficiently secured. Here, even when an integrated roof panel is used in which the secondary waterproof layer projects to the underwater side of the roof panel (some projects also in a horizontal direction), the first insertion hole 24a is used. Since the bolts 5 can be respectively inserted from the lateral direction into the second insertion holes 24b, installation work of such a roof panel with a secondary waterproof layer can be performed efficiently.

  If the roof panel 3 can be temporarily placed on the deposit plate portion 23 of the bundle 2, the installation operation of the roof panel 3 can be performed relatively easily and efficiently.

  Further, even with a flat roof as described above, it is possible to accurately add a water gradient to the roof. Of course, the structure of the roof of the present application is not limited to a flat roof.

  Further, in the case of the bundle 2, the upright plate portion 24 to which the roof panel 3 is fixed does not need to be provided at an inclination angle that matches the water gradient of the roof, and the first insertion hole 24 a and the second Since the water gradient of the roof can be formed by the difference in the height of the insertion hole 24b, the fabrication is easy and the accuracy of the gradient is easily obtained.

  As mentioned above, although embodiment of this invention was described with reference to drawings, this invention is not limited to the thing of embodiment shown in figure. Various modifications and variations can be made to the illustrated embodiment within the same range or equivalent range as the present invention.
