Description

  The present invention relates to a roof material pressing plate for pressing the roof material when the roof material is fixed to a building.

  Conventionally, so-called flat roofs, snowless roofs, and the like have a structure in which a roof material, a waterproof sheet, and the like are laminated on the upper surface of a building. For example, in JP-A-11-131705, a heat insulating material, a walking support plate made of a hard vinyl chloride resin foam, an insulating material, and a waterproof sheet are laminated on the upper surface of a building. In addition, a waterproof roof structure has been proposed in which the walking plate and the insulating material are pressed and fixed by a disk-shaped washer attached to the top of a fastener, and the waterproof sheet is laid thereon (patent) Reference 1).

Japanese Patent Laid-Open No. 11-131705

  However, in the invention described in Patent Document 1, since there is no specific description about the washer, the roof material such as a heat insulating material is not pressed by a special structure, and a very general pressing function is achieved. It seems that there is. Further, the pressing force pressed by the washer depends on the outer diameter of the washer, and in the case of a general washer, the area is much smaller than the area of the roofing material. Therefore, there is a problem that the roof material is destroyed or falls without being able to withstand a strong external force due to a typhoon or the like. In particular, a flat roof or a snow-free roof was easily damaged because it was difficult to reinforce even though stress was likely to concentrate on the rising part of the outer periphery.

  In addition, the roof is exposed to the harshest environment in the structure of the building, such as being directly exposed to heat from the sun and becoming hot, or being exposed to wind, rain, and snow. In general, the member used for reinforcing the roofing material is preferably a metal material in terms of cost and strength. However, when exposed to a high temperature, distortion due to thermal expansion may occur, which may reduce strength and waterproof performance. In particular, since the corners of the rising portion on a flat roof or the like are formed substantially vertically, the waterproof sheet must be cut and then fixed with an adhesive or the like, and a gap is likely to occur. Since such a gap generated between the heat insulating material and the waterproof sheet leads to rain leakage and a decrease in heat insulating performance, sufficient measures are required.

  The present invention has been made to solve such problems, and provides a roofing material pressing plate that can reinforce the roofing material corresponding to the use environment such as typhoon, wind and snow, and thermal expansion. The purpose is to do.

  The roofing material pressing plate according to the present invention is a roofing material pressing plate that is disposed between the washer and the roofing material and presses the roofing material when the roofing material is fixed to the building with a washer and a fastener, A plurality of fastening holes through which the fastener is inserted through the washer are formed at predetermined intervals in the longitudinal direction of the scale-shaped plate body, and around each of the fastening holes, thermal expansion causes A plurality of thermal expansion absorption holes capable of absorbing strain are formed.

  As one aspect of the present invention, the fastening hole may be formed larger than the thermal expansion absorption hole and smaller than the outer diameter of the washer.

  Furthermore, as one aspect of the present invention, the plate body includes a bottom plate and a side plate each having a curved bent portion and having a substantially cross-sectional L shape, and the bottom plate and the side plate include a plurality of plates. The fastening hole and a plurality of the thermal expansion absorption holes may be formed.
