A siding straightening tool includes two arms engaged with one or more ratchets; one or more spikes extending from the one or more ratchets; a release engaged with one of the two arms and to allow the arms to release; and a mold extending from the one or more arms, the mold having a groove; the two arms clamp together, thereby bringing the spikes toward each other; the mold is ratcheted down to straighten a piece of siding; and the two arms pivots via the one or more ratchets thereby engaging the mold and disengaging the mold with the siding.

A connection assembly includes a first concrete member, a second concrete member, and a cap formed of a concrete material. The first concrete member has an end surface and a plurality of reinforcing bars protruding from the end surface. The second concrete member has a plurality of opening walls defining an opening extending through the second concrete member. The second concrete member is disposed on the end surface of the first concrete member with the reinforcing bars disposed in the opening. The cap is cast in the opening around the reinforcing bars and is spaced apart from each of the opening walls.

A panel may include a substrate and a top layer provided on the substrate. The top layer may include a printed motif provided on a paper sheet and a transparent or translucent synthetic material layer. The paper sheet may be impregnated with polyurethane or polyisocyanate. The synthetic material of the transparent or translucent synthetic material layer may be polyurethane.

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.

Floor panels which are provided with a mechanical locking system including an extruded flexible tongue in a sidewardly open groove which during a vertical folding motion is bent horizontally. A tongue adapted for being received in a sidewardly open groove of a floor panel, wherein the tongue, which is an elongated extruded section, when received in the groove is bendable in a plane substantially parallel with a front face of the floor panel, such that the tongue is at least partially resiliently displaceable inside said sidewardly open groove in said plane during locking of the floor panel with another floor panel and wherein a vertical protrusion, serving as a friction connection between the tongue and the groove, is arranged at an upper or lower part of the tongue, wherein the tongue has a length in the longitudinal direction of the tongue and a total width perpendicular to the length, and the total width varies in the longitudinal direction of the tongue.

An interface for a structural member includes at least one first sidewall that extends from a first end along a longitudinal direction and defines a first cavity. The at least one first sidewall defines a female end section and includes a transversely oriented female end surface at the first end. The interface also includes at least one second sidewall that extends from a second end along the longitudinal direction and defines a second cavity. The at least one second sidewall defines a male end section adjacent the second end and configured to be received within the first cavity, and a stop surface offset longitudinally from the second end and oriented to bear against the female end surface in substantially face-to-face contact when the male end section is received within the female end section. The stop surface and the male end section are integrally formed and monolithic.

A connection assembly includes a first concrete member, a second concrete member, and a cap formed of a concrete material. The first concrete member has an end surface and a plurality of reinforcing bars protruding from the end surface. The second concrete member has a plurality of opening walls defining an opening extending through the second concrete member. The second concrete member is disposed on the end surface of the first concrete member with the reinforcing bars disposed in the opening. The cap is cast in the opening around the reinforcing bars and is spaced apart from each of the opening walls.

A floor panel has a rectangular and oblong shape, and includes a substrate and a top layer provided on the substrate and forming a decorative side of the floor panel. The top layer is composed of a print provided on a carrier sheet and a transparent thermoplastic layer situated above the print. The substrate has a thickness from 2 to 10 millimeter and forms at least half of the thickness of the floor panel. The substrate is a polyurethane-based substrate and the transparent thermoplastic layer is polyurethane-based. The floor panel has a length of more than 1.1 meters and has a plurality of reinforcing layers situated outside the center line of the substrate. A reinforcing layer may be provided in combination with the substrate and the top layer.
