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, when the sheet-like construction material for constructing the steel structure is constructed on the base part, a coil shape with a predetermined width (about several tens of cm to about 1 m) is formed. In the case of a roof (including the rooftop of a building), this is a member that is spread out during construction, while the adjacent locations are polymerized, and the overlapped locations are fixed with a fastener a provided with a washer. Then, the superposed part and the fastener a part are covered with a cover b, and bonded 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. Due to the distortion and the like, swelling and distortion occur, and a water pool [see FIG. 9B] can be formed, which causes a cause of rain leakage.

Further, 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 the above-mentioned drawbacks of the sheet-like envelope, and the problem to be solved by the present invention (technical problem or object) is to reduce the occurrence of surface swelling and distortion. However, the present invention 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.

This has the advantage that the cause of the water pool can be reduced. Furthermore, by pressing to a certain extent with the partial presser piece, the shear strength generated at the tightening part and the tightening part generated at the time of negative pressure at the overlapping positions of the construction materials increases, and it is strong against negative pressure such as strong winds. There is an effect that can be done. Moreover, even if a partial presser piece is provided, it can be easily and quickly constructed. Furthermore, in claims 2 and 3, the same effect as in claim 1 is obtained.

The sheet portion 2 does not include a plasticizer as an additive for imparting flexibility. Specific examples of the plasticizer include phthalate esters, but the phthalate esters are excluded from the sheet portion 2.

  As such a chemical substance that does not adversely affect the environment, there is an embodiment in which the sheet part 2 is formed from an olefinic compound as a chemical substance that does not contain chlorine. Since the sheet part 2 formed from the olefinic compound does not generate dioxin at the time of incineration, the construction material A constituting the roof, the wall, etc. after the service life has been removed from the enclosure such as a building structure, The old construction material that was removed when it was replaced by firewood does not generate dioxin even if it is incinerated, and can contribute to environmental protection.

  The sheet part 2 is heated while moving hot air at around 500 ° C. at a speed of 1 to 3 m / min. After the heating, the sheet part 2 can be fused with each other by pressing. is there. An adhesive is used for joining the sheet portion 2 and the metal thin plate portion 1. Specifically, an adhesive is layered between the metal thin plate portion 1 and the sheet portion 2. As the adhesive, one having heat resistance is used, and a chloroprene rubber-based adhesive or a nitrile rubber-based adhesive is preferable.

When the overlapping positions of the adjacent construction materials A and A are pressed by the partial presser piece 3, a certain degree of distributed loads f, f,... Are obtained at the three partial presser pieces as shown in FIG. Therefore, the conventional fastener can be made much stronger than one place. Furthermore, it can be integrated and solidified with the base portion 6.

  Further, as shown in FIGS. 5 and 6 and the like, the binding tool 5 may be constituted by a shaft-like fastening part 5a such as a drill screw and a head part 5b, or may be constituted as a rivet.
