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

Abstract

An anchor-free system for fastening cladding panels is composed of a two-element hanger. An upper element of the hanger is connected with a bottom element of the hanger. The contact area of this connection forms a shelf. There is an opening to accommodate an adjustment bolt. The upper element of the hanger has the form of a vertical wall closed in the bottom with a horizontal or inclined shelf having openings for screws. The vertical wall of the upper element of the hanger has a tongue located at an angle relative to the vertical wall of the upper element of the hanger. The bottom element of the hanger has the form of two vertical walls connected in the top with a horizontal or inclined shelf having openings for the screws. The vertical wall of the bottom element makes a hitch for the base profile of an installation substructure.

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.
