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 is 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.

3. The anchor-free system as claimed in claim 1, wherein the shelf of the upper element of the hanger being an aluminum profile with ledges on its bottom side, and the shelf of the bottom element of the hanger has a recess.

4. The anchor-free system as claimed in claim 1, wherein the shelf connecting the upper element of the hanger with the bottom element of the hanger is horizontal or is inclined relative to the level line.

5. The anchor-free system as claimed in 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 as claimed in claim 1, wherein a length and width of installation grooves located on the non-visible surface of the cladding panel correspond to a length and width of the tongue of the two-element hanger.

7. The anchor-free system as claimed in claim 1, wherein the two element hangers are casts, extruded profiles or are extruded from steel plate.

8. The anchor-free system as claimed in claim 1, wherein the upper element of the hanger is connected with the bottom element of the hanger by one or more of rivets, screws, adhesive or a special tongue and inlet type of connection in a direction of ledge insertion into the bottom element of the hanger.

9. A method of fastening an anchor-free system for fastening of cladding panels, which consists in installation of hangers on a metal base profile of the substructure, gluing hangers to invisible non-visible side or surface of a cladding panel, with at least two installation grooves directed at an angle towards the inside of the non-visible surface, where installation grooves have the shape of an elongated incision, with a length and width corresponding to a length and width of the tongue of the two-element hanger and afterwards, the tongue of the bottom element of the hanger, which is inclined at an appropriate angle relative to the groove, is inserted along the direction of depth of one of the installation groove, after which the tongue of the upper element of the hanger is inserted along the direction of depth of another installation groove, after which the upper element of the hanger and the bottom element of the hanger are one or more of riveted, screwed or bolted together, wherein each component of the two-element hanger is attached to the non-visible surface of the cladding panel and aligned with the installation groove.

10. The method as claimed in claim 9, wherein prior to insertion of the tongue the installation grooves of the two-element hanger are filled in with an adhesive.

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

12. The method as claimed in claim 9, wherein the installation of the two-element hanger in installation grooves is made in any order.

13. The method as claimed in claim 9, wherein each element of the two-element hanger is provided with the tongue the inclination of which corresponds to the inclination angle of the installation groove.

14. The method as claimed in claim 9, wherein two-element hangers with the adjustment bolt are attached to the non-visible surface of the cladding panel in its top corners, wherein the adjustment bolt rests on the metal base profile.
