AI summary

The present invention relates to a bracket (1) for damping forces between a wall (17) and a floor (18) of a building. The bracket (1) comprises a first and a second anchoring plate (2, 3), at least two cylindrical channel elements (4) connected to the first anchoring plate (2) and at least one cylindrical channel element (5) connected to the second anchoring plate (3). The bracket (1) is characterized by a radial damping element (13) inside each cylindrical channel element (4, 5), the radial damping element(s) (13) thereby providing damping of radial forces between the anchoring plates (2, 3), and at least one axial damping element (6) damping axial forces between the anchoring plates (2, 3), wherein a connection member (9) is extending though a through-hole (14) of each radial damping element (13) and a through-hole of said axial damping element (6). Thus, a bracket (1) according to the present invention permits damping in at least two substantially different directions, preferably in a radial direction and an axial direction.
