Various embodiments of interconnectable pieces are described that collectively form a surface. The pieces comprise one or more routed edges or cutouts that can be configured to receive an insert used to couple adjacent tiles to one another. Some inserts may comprise one or more magnets or magnetized portions to magnetically couple the pieces with adjacent pieces.

Various embodiments of flooring and other tiles are described that comprise one or more magnets and/or routed edges to connect adjacent tiles to one another. Some tiles may comprise a set of magnets or magnetized portions to connect with an adjacent tile having a set of magnets of opposite polarity.

A floor covering, made of floor elements, which, at least at two opposite sides, include a male coupling part and a female coupling part, which allow that two of such floor elements can be interconnected at the respective sides at the respective sides by pushing one of these floor elements with the associated male coupling part, by a downward movement, home into the female coupling part of the other floor element. At least one of the coupling parts, either the male coupling part or the female coupling part, is made at least partially in a filled synthetic material composite, such as extruded wood.

The present disclosure relates to interior material attachment structure with wall attachment part bolt grooves, including: binding protrusions formed at the outermost part of the interior material attachment structure in order to attach the metal interior material; and connection part grooves formed adjacent to the binding protrusions in order to connect the plurality of interior material attachment structures to each other.

A modular construction system, including, first and second walls, each having first and second broad surfaces. Each wall includes throughgoing connector-receiving bores. The modular construction system further includes a connector including a longitudinal body portion arranged along a longitudinal axis and having a first width. A head portion of the longitudinal body portion includes a base surface having a second width in a direction transverse to the longitudinal axis. A pair of protrusions extend outwardly from the longitudinal body portion and are disposed between the base surface and a tail end of the longitudinal body portion. The protrusions include an engagement surface facing toward the base surface and having a third width, the third width being greater than the first width.

Floor panels are shown, which are provided with a mechanical locking system comprising tongue and grooves provided with protrusions and cavities which are displaceable in relation to each other and configured such that the protrusions can obtain a vertically unlocked position where they match the cavities and a vertically locked position where the protrusions overlap each other.
