The fastening system (10) comprises a bush (11), and a fastener (12), which comprises a shaft (13) formed for anchoring and a head for fixing the bush on a solid substrate (16) such as a facade or a flat roof of a building by inserting the fastener. The bush comprises a sleeve, in which a part of the shaft of the fastener extends. The sleeve has an inner diameter, which is equal to or smaller than the diameter of the head so that a region of a reservoir surrounding the part of the shaft of the fastener is formed in the sleeve. The fastening system (10) comprises a bush (11), and a fastener (12), which comprises a shaft (13) formed for anchoring and a head for fixing the bush on a solid substrate (16) such as a facade or a flat roof of a building by inserting the fastener. The bush comprises a sleeve, in which a part of the shaft of the fastener extends. The sleeve has an inner diameter, which is equal to or smaller than the diameter of the head so that a region of a reservoir surrounding the part of the shaft of the fastener is formed in the sleeve, where the formed region is limited at one end by a bottom side of the head, sealed by the head at an inner wall of the sleeve and is narrowed to a cannula or a cannular opening at an other end by a substrate-side end portion of the sleeve so that by the sleeve, the fastener, the head and the reservoir an injection syringe is formed. A sealant fillable in the reservoir is applied or injectable on or in or under the substrate by setting the fastener. The shaft comprises an anchoring thread, at which a notch is mounted for the transportation of the sealant under pressure of the sleeve, and is formed as the shaft of a nail. The sleeve consists of a resilient material and a mechanically durable deformable material. The cannula and the cannular opening: are closed with a sealing element at the end of the substrate-side end portion of the sleeve and opened to form the outlet opening for the sealing element; and have an inner diameter, which is equal to an outer diameter of the shaft. The sleeve has a greater wall thickness in the region of the reservoir than in a region outside of the reservoir. The substrate-side end portion of the sleeve is formed axially compressible. The sleeve is a tube made of plastic or aluminum. The unset fastener is seated on an upper edge of the sleeve, and protrudes at an opposite end of the cannula or cannular opening. The head of the fastener conically extends upward on its underside of the shaft. The substrate-side end portion of the sleeve is formed as an anchor on a part of its length. An independent claim is included for a method of sealing a joint between a fastening system and a solid substrate such as a facade or a flat roof of a building. |
