Problems solved by technology

[0005] However, the problem arises here that, due to the oblique position of the anchor rod, the sealing element is overloaded, so that when the concrete is poured, fluid concrete can flow out of the unsealed position of the anchor passage hole

Embodiment Construction

[0030] The figures show the subject matter according to the invention very schematically and are not to be understood to scale. The individual components of the subject matter according to the invention are shown in such a way that their structure can be clearly shown.

[0031] exist Figure 2a , 2b and 3 are shown in figure 1 A detailed view of the concrete wall formwork according to the invention shown in , wherein a sectional view at the height of the longitudinal axis of the anchor rod 2 of the anchor system according to the invention is shown, which attaches the concrete wall A first and a second formwork element 5, 6 of the formwork are connected to each other. The formwork elements 5 , 6 each have a formwork shell 7 and stringers. Possible cross beams are not shown due to the selected graphic partial sections. The formwork shell 7 is usually attached, in particular riveted, to the longitudinal and transverse beams. The anchor rod 2 is oriented obliquely at an angl...

Abstract

The invention relates to a locking device (21) for an anchor bar (2) of an anchor system of a concrete wall formwork, having a formwork element (6) comprising a formwork facing (7), having an annular sealing element (15) for sealing off an anchor penetration hole (13) in the formwork facing (7), a threaded nut element (24) for threading the anchor bar (2) into a threaded nut thread of the threaded nut element (24), and a cap plate (27) that can be fastened by means of fastening means (30) to a rear face of the formwork element (6) of the concrete wall formwork and comprises a spherically designed plate region having an opening in which the threaded nut element (24) is disposed having radial clearance, wherein the threaded nut element (24) comprises a groove-like radially circumferential receptacle (40) in which the edges of the opening in the spherical plate region are received, and wherein a tubular guiding device (45) flush with the threaded nut thread of the threaded nut element (24) is provided on the end of the threaded nut element (24) to be located at the concrete formwork side. The sealing element (15) thereby comprises an elastic rubber inner sealing ring (46) and the free end (51) of the guiding device (45) to be located at the formwork element side is sealingly inserted with the inner sealing ring (46) into the sealing element (15).

Description

technical field [0001] The invention relates to an anchoring system for concrete wall formwork with at least one locking device for an anchor rod of the anchoring system, wherein the locking device has a nut element for passing through a nut thread of the nut element Twist the anchor rod. Background technique [0002] This anchoring system is used in formwork technology when pouring reinforced concrete buildings. The concrete formwork elements or formwork elements for short of the concrete wall formwork are formed in each case from a formwork shell and a plurality of support elements, such as longitudinal beams and transverse beams. Both sides of the wall are each formed by a concrete formwork element, ie formwork half, which are held together by anchor rods. The anchor rods are inserted through the openings in the formwork casing and are fastened at their ends to the elements supporting the formwork casing in such a way that the tensile forces acting on the anchor rods du...
