Description

  The present invention relates to a scissors attachment tool for attaching scissors such as eaves and vertical scissors to a building site such as a cement-based nose plate and a cement-based wall.

  Conventionally, a polycarbonate resin made of polycarbonate resin is known as an eaves fixture for attaching eaves such as eaves and vertical eaves to a building part such as a nose plate or a wall. The tool does not rust like metal, and has the feature of high strength.

  The conventional example of the polycarbonate resin cage attachment shown in the above-mentioned Patent Document 1 is for attaching to a nose plate made of a vinyl chloride-coated steel cage containing a plasticizer, and the building of the fixing part of the cage attachment A separate additive barrier film is attached to the side surface with a double-sided adhesive tape, or the additive barrier film is integrally molded so as to cover the heel fixture by simultaneous molding when the heel fixture is molded. Is.

  However, in the above conventional example, when the separate additive-blocking film is attached to the building-side surface of the fixing part of the anchorage fixture, the additive-blocking film protrudes from the fixed part due to a positional shift when the double-sided adhesive tape is applied. There is a problem that the construction finish is poor, or that the one formed by simultaneous molding is expensive to manufacture.

  Moreover, when fixing the anchorage to the building, it is fixed by inserting a fixing tool such as a screw into the insertion hole provided in the fixing part and screwing it into the nose plate or wall of the building. The plasticizer is transferred to the insertion hole of the fixing portion through the screw, but the polycarbonate is exposed at the inner periphery of the insertion hole, and the insertion hole portion is affected by the plasticizer. Further, the insertion hole portion is a portion where the tightening stress of the screw tightening is concentrated, and there is a problem that cracks are generated from the insertion hole portion due to the influence of the plasticizer and the stress concentration of the screw tightening.

  In addition, the conventional example shown in the above-mentioned Patent Document 1 uses vinyl chloride in order to eliminate the influence of the plasticizer when attaching the polycarbonate resin heel fitting attached to the nose plate made of vinyl chloride-coated steel heel containing plasticizer. It is only disclosed that an additive-blocking film for blocking the plasticizer added to the resin is provided. When mounting a cage made of polycarbonate resin on a cement-based nose plate or cement-based wall, etc. It is not disclosed how to prevent the influence of alkali components that migrate from a nose plate or a cement-based wall to a polycarbonate resin scissor fixture.

In particular, when fixing to a cement-based part of a building such as a cement-based nasal plate or cement-based wall with a fixing tool, the cement powder enters the insertion hole of the fixing portion where the fixing tool is inserted, and the alkali of the cement powder. The insertion hole part of the fixing part (the area around the insertion hole) where the component affects the inner peripheral surface of the insertion hole of the fixing part where the polycarbonate resin is exposed and the stress is concentrated by the fixing of the fixing tool. There is a problem in that cracks are likely to occur at the part), and this point needs to be solved.
