A thermoplastic-based building panel, such as a floor panel. The building panel includes an upper layer arrangement, a lower layer arrangement, and a balancing layer provided between the lower and the upper layer arrangement. The building panel further includes a groove arrangement including grooves. A thermoplastic-based building panel including an upper layer arrangement and a balancing layer which is a bottom layer of the building panel. The building panel includes a groove arrangement, wherein a major portion of the grooves therein is provided in the balancing layer only. A thermoplastic-based building panel including a mechanical locking system for horizontally and/or vertically locking the building panel to an adjacent building panel. The mechanical locking system includes a cooperating surface which is situated in a balancing layer and is configured to cooperate with a cooperating surface of an adjacent building panel.

This invention relates to a deck board and more particularly, to a reduced material deck board. In accordance with this invention there is provided a deck board comprising an operatively upper board section having at least one operatively downwardly depending support leg terminating in at least one flange, an underside of the flange having a concave surface.

A façade structure and/or wall structure for a building which includes comprises tiles (1) and a support structure (2), in which the tiles (1) are received oriented in each case in the vertical plane. The support structure (2) has taut tension elements (3) with bearing bodies (4) fastened thereto, wherein the taut tension elements (3) are preferably formed as taut support cables or as taut tension rods or the like. The several, or at least one, of the tiles (1) received in the support structure (2) are held directly or indirectly supported on the bearing bodies (4) with a weight-supporting bearing, and/or are held locked by means of the bearing bodies (4). The several or at least one of the bearing bodies (4) are or is attached axially fixed exclusively to tension elements (3) oriented vertically in the support structure (2).

A façade structure and/or wall structure for a building which includes tiles (1) and a support structure (2), in which the tiles (1) are received oriented in each case in the vertical plane. The support structure (2) has taut tension elements (3). The tiles (1) received in the support structure (2) are mounted in a weight-supporting manner and/or held locked by means of one or more of the allocated tension elements (3), directly and/or via bearing bodies (4) attached to the tension elements (3). The several or at least one of the tiles (1) are or is allocated in each case at least one holding element (5). For anchoring to the tile (1), the holding element (5) has at least one anchoring portion that can be anchored in a receiver (1hn) of the tile, and/or cooperates with an anchor (6) received in a receiver (1hn) of the tile (1), and wherein the holding element (5) has at least one tension element gripping portion for gripping on at least one of the tension elements (3) allocated to the tiles (1).

A construction system (1) for wall cladding having uprights (2) and cross-members (3) to be held between two uprights not aligned vertically, in which the cross-members (3) have two opposing terminals (33) of a deformable material with two bends. The uprights (2) have an anchor (22) where terminals (33) of the cross-members can be attached, with the anchor, for this purpose, having, for each terminal (33), at least two entry parts (A, B) arranged spatially to maintain the relationship with the two bends (a, b) of the terminal, with each bend insertable into one of the entry parts, first requiring elastically deforming one terminal (33) or the upright such that the bends are pressed against the entry parts. The system can be completed with a series of cladding pieces (10) prepared to be suspended from one or more cross-members (3) at the same time.
