    • The invention relates to a connection device for flat substrates, in particular for PMMA sheets, GRP sheets, plastic sheets or light metal alloy sheets, comprising an annular disk (1) which has on its outer lateral surface (3) a surface structure (4) for anchoring in the flat substrate (17) and through which passes a clamping screw (8) having a screw head (9) and a shank (10) with external thread (11), and a nut (18) which can be screwed onto the external thread (11) for clamping the annular disk (1) axially between the screw head (9) and the nut (18), wherein the annular disk (1) can be widened in the radial direction as a consequence of the clamping between the screw head (9) and the nut (18) in order to clamp the annular disk (1) against the internal circumference (19) of a bore, preferably formed as a blind bore, in which the annular disk (1) can be received, and in so doing anchor the surface structure (4) in the radial direction in the substrate material of the inner circumference (19) of the bore (16). According to the invention, it is provided that the clamping screw (8) has, in the region of its forward shank end oriented away from the screw head (9), in particular on the end face, a drive, preferably in the form of a drive recess, preferably a polygonal or multi-lobed recess.
    • 本发明涉及一种用于平面基板的连接装置,特别是用于PMMA片材,GRP片材,塑料片材或轻金属合金片材的连接装置,包括环形盘片(1),其外侧表面(3)具有表面结构(4) ),用于锚固在平面基板(17)中,并且通过具有螺纹头(9)的夹紧螺钉(8)和具有外螺纹(11)的柄(10),以及可以被拧紧的螺母(18) 到外螺纹(11)上,用于将环形盘(1)轴向夹紧在螺钉头(9)和螺母(18)之间,其中环形盘(1)可以由于夹紧而在径向上加宽 在螺钉头(9)和螺母(18)之间,以便将环形盘(1)夹紧在优选形成为盲孔的孔的内圆周(19)上,其中环形盘(1)可以 并且在内周的基板材料中将表面结构(4)沿径向方向锚固 孔(16)的e(19)。 根据本发明,提供了夹紧螺钉(8)在其前柄端部远离螺钉头(9)的区域中,特别是在端面上具有优选为 驱动凹槽,优选地是多边形或多凸起的凹部。
