Description

  The present invention relates to a sheet-like envelope and a method for constructing the sheet-like envelope that can increase the strength of the overlapping portion of the sheet-like envelope while preventing the occurrence of swelling and distortion on the roof surface.

  2. Description of the Related Art In recent years, a large number of construction materials that are waterproof and airtight on a rooftop or the like have been constructed by construction materials configured in a sheet shape. In particular, when waterproofing can be performed on a rooftop, planting, etc., an enclosure having such waterproofness is suitable. This type of construction material uses a sheet material made of a synthetic resin, and is laid on the base portion, and the adjacent construction materials are constructed through fixing tools such as screws and nails. Adjacent construction materials are joined together by an adhesive or heat fusion.

  Such an envelope made of sheet-like construction material has a surface that is excellent in waterproofness and airtightness, but is particularly cautious during construction, and the construction materials are surely joined together. It must be. If this surface is neglected, not only is the waterproof property poor, but once the waterproof property is poor, the repair becomes extremely difficult. Here, “tightening” is a fixing structure between a construction material and a base part (mainly a purlin or trunk edge, deck plate, and concrete), and “tightening” described below is a bonding between construction materials. It is a configuration.

  Moreover, the sheet-like envelope in which the metal thin plate portion and the synthetic resin sheet portion in FIG. 2 of Patent Document 1 are synthesized is excellent in waterproofness and airtightness. As shown in FIG. 8 and FIG. 9, the sheet-like construction material for constructing this is a steel structure constructed on the base part. With a predetermined width (about several tens of cm to about 1 m), In the case of a roof (including a rooftop of a building) which is a coil-shaped member, the adjacent portion is superposed while spreading at the time of construction, and the overlapping portion is provided with a washer. In this case, the superposed portion and the fastener a location are covered with a cover b and joined by heat fusion or the like. In this case, a heat insulating material is often laid on the base part, and in the end region of the constructed sheet-like construction material, heat due to unevenness of the base part or thermal expansion due to an increase in the outside air temperature of the thin metal plate part, etc. Swelling and distortion are generated due to distortion and the like, resulting in a puddle (see FIG. 9B) and inducing the cause of rain leakage.

Furthermore, conventionally, there is a drawback in that the connection relationship between the construction materials is weak because only the fasteners (with washers) are provided at predetermined intervals. An object of the present invention is to solve various disadvantages of the sheet-like envelope described above, and the problem (technical problem or object) to be solved by the present invention is the occurrence of surface swelling / distortion. It is to realize a sheet-like envelope and a method for constructing the sheet-like envelope that can increase the strength of the tightening portion and the tightening portion while preventing the above-described problem.
