The invention relates to a non-
keel dry-hanging
fastener which belongs to the technical field of parts or structures especially used as fixing material during decorating walls of buildings. The non-
keel dry-hanging
fastener solves the problem that thermal-insulation decoration plates have no
keel dry-hangings and comprises a clip and a fastening piece, wherein, the clip is an expansion bolt, and the center of the
threaded rod of the expansion bolt is provided with an inner-threaded round hole; the fastening piece is connected with the
threaded rod of the expansion bolt by a screw. The fastening piece consists of a top plate and a base plate which are respectively provided with a round hole. The
fastener provided by the invention is made of stainless steel or
metal, the surface of which is treated to
resist against
corrosion, and realizes that thermal-insulation decoration plates have no keel dry-hangings, so that thermal-insulation decoration plates can be perfectly fixed on walls. The fastener is applicable to various wall materials, such as concrete,
solid and hollow walls and can make constructions and maintenance convenient and quick. The fastener has
high loading capacity, high bearing pressure and good tension-resistance performance; besides, the fastener can prevent the
impact damage, reduce the loading of a whole building, provide 3-5 cm horizontal adjustment differences for the distorted surfaces of walls, and provide flat surfaces for wall decoration.
