Anchor-free system for fastening of cladding panels and a method of fastening thereof

1. An anchor-free system for fastening a cladding panel, comprising:

a metal base profile; and

a two-element hanger, wherein an upper element of the hanger comprises a vertical wall closed in a bottom with a first shelf having an opening for an adjustment bolt, the vertical wall of the upper element of the hanger is provided with at least one first tongue located at an angle relative to the vertical wall of the upper element of the hanger;

wherein a bottom element of the hanger comprises two vertical walls connected in a top with a second shelf having an opening for the adjustment bolt, one of the two vertical walls of the bottom element of the hanger is provided with at least one second tongue located at an angle relative to the one of the two vertical walls, and

wherein when the anchor-free system is in use, the first shelf and the second shelf are connected to each other by a fastener, the metal base profile is received in a space defined by the two vertical walls of the bottom element of the hanger, the at least one first tongue and the at least one second tongue are received in respective installation grooves on a non-visible side of the cladding panel.

2. The anchor-free system of claim 1 , wherein the at least one first tongue of the upper element of the hanger, and the at least one second tongue of the bottom element of the hanger, after the first shelf and the second shelf are connected to each other by the fastener, converge towards each other at an angle facing a center of the two-element hanger or diverge at an angle, directed outside the center of the two-element hanger.

3. The anchor-free system of claim 1 , wherein the first shelf of the upper element of the hanger comprises an aluminum profile with a ledge on a bottom side thereof, and the second shelf of the bottom element of the hanger has a recess to receive the ledge.

4. The anchor-free system of claim 1 , wherein the first shelf and the second shelf are horizontal.

5. The anchor-free system of claim 1 , wherein a length of each tongue of the two-element hanger corresponds to a width of the two-element hanger and, the tongues are placed one under another or along the width of the two-element hanger and in one row, where two or more tongues are accommodated.

6. The anchor-free system of claim 1 , wherein a length and a width of each installation groove located on the non-visible side of the cladding panel correspond to a length and a width of the respective tongue of the two-element hanger, respectively.

7. The anchor-free system of claim 1 , wherein the two-element hanger is cast, an extruded profile or is extruded from a steel plate.

8. The anchor-free system of claim 1 , wherein the first shelf and the second shelf are connected to each other by one or more of rivets, screws, adhesive or a tongue and inlet type of connection in a direction of ledge insertion into the second shelf.

9. A method of using an anchor-free system to fasten a cladding panel, the anchor-free system comprising a metal base profile, and a two-element hanger comprising a first element of the hanger and a second element of the hanger, the first element of the hanger comprising a vertical wall closed in a bottom with a first shelf having an opening for an adjustment bolt, the vertical wall of the first element of the hanger is provided with at least one first tongue located at an angle relative to the vertical wall of the first element of the hanger, the second element of the hanger comprises two vertical walls connected in a top with a second shelf having an opening for the adjustment bolt, one of the two vertical walls of the second element of the hanger is provided with at least one second tongue located at an angle relative to the one of the two vertical walls, the cladding panel has installation grooves on a non-visible side thereof for the at least one first tongue and the at least one second tongue, the method comprising:

inserting the at least one second tongue of the second element of the hanger into a respective installation groove of the cladding panel;

inserting the at least one first tongue of the first element of the hanger into a respective installation groove of the cladding panel;

connecting the first shelf and the second shelf with each other by a fastener; and

using a space defined by the two vertical walls of the second element of the hanger to engage the metal base profile so that the two-element hanger and the cladding panel are supported by the metal base profile.

10. The method of claim 9 , wherein the installation grooves are filled in with an adhesive.

11. The method of claim 9 , wherein an adhesive is applied to an area of contact between the two-element hanger and the non-visible side of the cladding panel.

12. The method of claim 9 , wherein the inserting the at least first tongue and the at least second tongue of the two-element hanger in the installation grooves is made in any order.

13. The method of claim 9 , wherein the angle of each tongue of the two-element hanger corresponds to an inclination angle of the respective installation groove.

14. The method of claim 9 , wherein the installation grooves are located in a top corner of the cladding panel, and wherein the adjustment bolt rests on the metal base profile.

15. The anchor-free system of claim 1 , wherein the first shelf and the second shelf are inclined.

16. The anchor-free system of claim 1 , wherein the adjustment bolt is received in the openings of the first shelf and the second shelf and is used to adjust a vertical position of the cladding panel relative to the metal base profile.

17. The method of claim 9 , further comprising using the adjustment bolt to adjust a vertical position of the cladding panel relative to the metal base profile.
