And the resin-made sheet | seat 5 which has damping performance is stuck on the lower surface of this roof material 4, and the said simple roof P is comprised.

  The support column 1 is made by cutting a steel pipe into an appropriate length, and a bolt hole for attaching the main beam 2 through the holder 6 is drilled through the side wall at an upper portion thereof. A fixture 71 for attaching the vertical rod 7 is attached to the frame. The material of the support column 1 is not limited to the above-described steel pipe, and may be an aluminum alloy extrusion mold material or the like, but a steel pipe that is stable in strength and inexpensive is preferably used.

  The main beam 2 is made by bending a steel pipe in an arc shape, and is attached to the upper end of the column 1 via a holder 6 that holds the base end of the main beam 2 and also holds the upper end of the column 1. Then, a substantially L-shaped bracket for attaching the purlin 3 is attached to the upper surface of the distal end portion, the upper surface of the proximal end portion, and the upper surface of the central portion of the main beam 2. The material of the main beam 2 is not limited to the above-described steel pipe, but may be an aluminum alloy extruded mold or the like, but a steel pipe that is stable in strength and inexpensive is preferably used.

  The purlin 3 is produced by cutting steel pipes to appropriate lengths, and through holes are formed in the lateral direction on a pair of opposing side surfaces, and bolts are inserted through the through holes and the substantially L-shaped metal fittings. The main building 3 and the main beam 2 are fixed by inserting another bolt through a mounting hole formed in the vertical direction of the main beam 2 and a substantially L-shaped support. Of course, the material of the purlin 3 is not limited to the above-described steel pipe, but may be an aluminum alloy extruded mold, but it is preferable to use a steel pipe that is stable in strength and inexpensive.

  The roof material 4 spanned between the main houses 3 is formed in a curved shape with substantially the same curvature as the arc-shaped main beam 2 and is screwed with tapping screws, bolts, etc. from above to form three main houses. 3 It is being fixed to the upper surface. The roof material 4 is formed by bending a rectangular steel plate in the long side direction and forming four ridges in the long side direction at equal intervals on both ends and the center of the short side. This can improve the strength as compared with the flat steel plate, and the roof material 4 can be constructed by sequentially superimposing the ridges at the ends thereof, so that the structure can easily cope with the difference in width of the simple roof P. . Further, under the roof material 4 on the base end side, a horizontal rod 8 that receives rain water dripping from the roof material 4 is supported by a support fitting and attached to the base roof 3 on the base end side.

  The holding tool 6 is composed of two plate materials with different right and left sides. The main beam 2 is attached to the upper end portion of the column 1 by sandwiching the column 1 and the main beam 2 from the left and right with the plate material and by clamping the side surfaces with bolts and nuts. The base end of is fixed. Therefore, the portion of the holder 6 that holds the column 1 and the portion that holds the main beam 2 are formed in an inverted L shape in side view so as to be in close contact with the outer diameter of the column 1 and the outer diameter of the main beam 2. ing. In addition, in order to improve the strength of the holder 6, a reinforcing plate portion 61 is integrally provided from a portion of the holder 6 that holds the support 1 to a portion that holds the main beam 2.

Examples of the thermoplastic elastomer include isoprene-based, olefin-based and ester-based elastomers. Of these, styrene-isoprene block copolymers are particularly preferably used.

  Examples of the thermoplastic resin include ethylene-vinyl acetate copolymer, polyolefin, vinyl chloride resin, and polyester. Among these, an ethylene-vinyl acetate copolymer is particularly preferable.

  Examples of the inorganic powder include metal oxides such as iron oxide, titanium oxide, and magnesium oxide, particulate metals, clay, talc, mica, quartz powder, and other mineral-based pulverized materials, glass fibers, glass powders, Examples include calcium carbonate and gypsum. Among these, mica and calcium carbonate are particularly preferable from the viewpoint of vibration damping characteristics and cost.

  If necessary, the resin composition may contain a heat stabilizer, a weather resistance improver, a lubricant, a processing aid, a pigment, a colorant, and the like.

  Although the thickness of the said resin-made sheet | seat 5 is suitably determined by a resin composition, damping performance, etc., 10 mm or less is preferable normally, More preferably, it is 2 mm or less.

  As an adhesive used when adhering the resin sheet 5 to the lower surface of the roofing material 4, for example, a rubber-based solvent adhesive, a two-component epoxy adhesive, a urethane adhesive, or the like can be used. Among them, a solvent type adhesive of chloroprene rubber that can impart vibration damping performance is particularly preferable. And the adhesive agent is apply | coated to the lower surface of the roofing material 4, and the resin-made sheets 5 are stuck from there. Of course, when the resin sheet 5 is formed, an adhesive layer may be integrally formed on one side thereof, and the surface on which the adhesive layer is formed on the lower surface of the roof material 4 may be pressed and stuck.

  In the present invention, the resin sheet 5 is adhered to the lower surface of the roof material 4 along the curve direction of the roof material 4 formed in a curved shape. Therefore, the roof material 4 is effectively reduced in vibration by the curved shape and the resin sheet 5 adhered along the curved direction of the curved shape, thereby reducing noise caused by raindrops.

  In the following, the embodiment according to the present invention different from the above embodiment will be described with reference to FIGS. 2 and 3. In particular, points different from the embodiment of FIG. Is omitted.

  In the form shown in FIG. 2, the holding tool 6 is composed of two plate materials with different left and right sides, like the form of FIG. 1, and sandwiches the column 1 and the main beam 2 from the left and right with the plate material, and the side is bolted.・ Although it is designed to be clamped with nuts, the central part of the main beam 2 is fixed to the upper end of the column 1, and the shape is not a reverse L-shape but a T-shape in side view. The reinforcing plate 61 is provided on both the left and right sides.
