Method and system for leveling a fastening element to be anchored in a substrate

1 . A method for leveling a fastening element to be anchored in a substrate, the method comprising:

installing an anchor in the substrate;

attaching an adjustment element that is height-adjustable along the anchor to the anchor;

arranging the fastening element on the adjustment element or on the anchor in another position defined by the adjustment element;

leveling the fastening element by adjusting the adjustment element from above using a leveling adapter, which is arranged at least in part above the fastening element and is configured to be gripped and operated from above; and

removing the leveling adapter and/or fixing the fastening element to the anchor in the position adjusted in this manner, wherein

the anchor is designed for use with chemical and mechanical anchoring systems;

before the adjustment element is attached, a pipe part or pipe material cut to a suitable length, corresponding to a distance from the substrate to the fastening element, is introduced on the anchor; and

after the fastening element has been leveled mortar is introduced or injected on the outside of the pipe part or pipe material between the substrate and the fastening element.

2 . The method according to claim 1 , wherein the anchor is designed

as a chemical anchor having a threaded rod; and/or

as a bolt anchor; and/or

as an expansion anchor; and/or

as an undercut anchor; and/or

as a screw anchor; and/or

for use in uncracked and/or cracked concrete as a substrate material; and/or

for dynamic or seismic loads.

3 . The method according to claim 1 , wherein the fastening element is designed as an anchor plate.

4 . The method according to claim 1 , wherein the leveling adapter

is a sleeve adapter which is designed to interlock with or connect to the adjustment element from above through a gap between the anchor and the fastening element in order to adjust the adjustment element, and/or

has a gripping portion arranged above the fastening element, with which a tool for applying a torque required for adjustment is configured to engage.

5 . The method according to claim 1 , wherein the adjustment element comprises a leveling washer.

6 . The method according to claim 5 , wherein the adjustment element has, in addition to the leveling washer, a pipe portion which is rigidly connected to the leveling washer, the pipe portion having an internal thread which is configured to can be brought into engagement with an external thread of the anchor.

7 . The method according to claim 1 , wherein after a predetermined mortar hardening time, a prestress is transferred to the anchor by a fixing threaded nut, optionally having a further washer.

8 . The method according to claim 1 , wherein the fastening element is a fastening element for mounting a parapet or glazing.

9 . The method according to claim 1 , wherein the adjustment element and the leveling adapter interlock or releasably interconnect through the fastening element.

10 . The method according to claim 4 , wherein the gripping portion is in the shape of a slit or hexagon.

11 . The method according to claim 5 , wherein the leveling washer is attached by screwing onto an external thread of the anchor.

12 . The method according to claim 1 , wherein the pipe part or pipe material is introduced on the anchor via an anchor thread thereof.

13 . A system for leveling a fastening element to be anchored in a substrate, wherein the system is designed to carry out the method according to claim 1 and, for this purpose, comprises the following:

at least one anchor, which is designed to be installed in the substrate;

for each anchor, the adjustment element which is designed to be attached to the anchor for positioning the fastening element; and

the leveling adapter,

wherein the adjustment element and the leveling adapter are designed in such a way that the adjustment element is adjustable for leveling the fastening element arranged thereon and/or fixed in its position in relation thereto by the leveling adapter, which is arranged at least in part above the fastening element and which is configured to can be actuated from above,

wherein the system is designed for use with chemical and mechanical anchoring systems and for this purpose, comprises the following:

for each anchor, the pipe part or pipe material that is configured to be cut to a suitable length, corresponding to a desired distance from the substrate to the fastening element, and that is designed to be pushed onto the anchor.

14 . The system according to claim 13 , further comprising the fastening element which is designed to be arranged on the adjustment element or on an anchor in another position defined by the adjustment element.

15 . The system according to claim 13 , wherein the fastening element is a fastening element for mounting a parapet or glazing.

16 . The system according to claim 13 , wherein the fastening element is an anchor plate.

17 . The system according to claim 13 , wherein the adjustment element and the leveling adapter interlock or releasably interconnect through the fastening element.

18 . The system according to claim 13 , wherein the pipe part or pipe material is configured to be pushed onto the anchor via an anchor thread thereof.
