A floor panel includes at least two reinforcing layers extending in a direction parallel to a plane defined by the panel to allow one of the at least two reinforcing layers to be situated at a level between 30˜70 percent of a thickness from a top surface of the panel to a highest part of a top surface of the tongue, and/or a bottom surface of the panel to a lowest part of an upper surface of the lower lip.

A flooring buckle has a buckle body with opposite sides and opposite ends that are transverse to the sides. The buckle body has four locking members extending outward from the buckle body. The flooring buckle has a I-shaped cross-section when viewed from the ends of the buckle body. The flooring buckle is symmetric about its vertical and horizontal center. The buckle body has a hole on an end that is configured to receive an expansion body. A diameter of the hole is sized smaller than a diameter of the expansion body. The flooring buckle is configured such that at least one of the four locking members is deformed and a portion of the deformed locking member engages a slot of a flooring panel when the locking member is inserted in the slot of the flooring panel and the expansion body is inserted in the hole of the buckle body.

Panel comprising a horizontally and a vertically active locking system, so that two such floor panels can be connected by means of a downward movement. The vertically active locking system comprises a locking element formed by an insert, formed by a coextruded strip. This comprises a blocking body, a securing section and a bending zone. The blocking body is substantially made of a first polymer; the bending zone is substantially made of a second polymer. The blocking body is substantially or entirely made of a mixture of the first polymer and the second polymer, or the bending zone is substantially or entirely made of a mixture of the second polymer and the first polymer.

A deck assembly includes a deck panel having a plate shape extending in a first direction and having a clip insertion groove recessed from each of both side surfaces thereof, a lower support disposed below the deck panel in a second direction that is perpendicular to the first direction, and a quick clip module coupled to one side surface of the lower support to fix the deck panel in a separable manner.

The present invention relates to panel, in particular a floor panel, a wall panel, or a ceiling panel, comprising a core layer, comprising a mineral or a cementitious material and at least one reinforcing layer situated in said core layer; wherein the panel, in particular the core layer, comprises a first pair of opposite edges, wherein a first edge of said first pair of opposing edges comprises a first coupling part, and wherein a second edge of said first pair of opposing edges comprises a complementary second coupling part, said coupling parts allowing a plurality of panels to be mutually coupled, wherein the first coupling part comprises a sideward tongue extending in a direction substantially parallel to a plane defined by the panel, and wherein the second coupling part comprises a groove configured for accommodating at least a part of the sideward tongue of another panel, said groove being defined by an upper lip and a lower lip.

The disclosure relates to a device for locking two interconnected floor panels that are identically embodied and includes a core, an upper side and a lower side, and a first lateral edge (I) and a second lateral edge (II) opposite the first lateral edge. On the upper side, the first lateral edge (I) of the first floor panel abuts against the second lateral edge (II) of the second floor panel. A horizontal groove extending into the core is embodied in the second lateral edge (II), with an upper wall, an inner wall and a lower wall, the lower wall being formed from a lower lip projecting on the first lateral edge (I), which, on the outer end thereof, has a projection that is oriented towards the upper side and has a first locking edge, and at least one locking element is inserted in the region of the connection point of the two floor panels. An outwardly projecting spring is provided on the second lateral edge (II), and includes a step forming a spring tip on the outer end thereof, and on the end thereof facing the core, a second locking edge extending in the vertical direction (V), the locking edge being the outer wall of a vertical groove open towards the lower side, in which the projection engages. The locking takes place, in the vertical direction, by means of the spring tip engaging in the horizontal groove, and in the horizontal direction, by means of the locking element supported on the first locking edge of the projection and on the second locking edge of the spring. The disclosure is characterised in that the locking element is compressible in the vertical direction (V) and not compressible in the horizontal direction.

The invention discloses a wooden floor with high utilization, a connection assembly, and a connection structure of a wooden floor with high utilization and a connection assembly. The wooden floor with high utilization includes a floor body. The floor body defines a first groove on one side surface thereof in a horizontal direction. The floor body defines a second groove on the other side surface thereof in the horizontal direction. The first groove and/or the second groove define a notch. The floor body of the present invention is merely required to define grooves on two sides thereof, and is not necessary to provide a protruding male buckle, as long as the first groove or the second groove is connected with a male buckle of the connection assembly, so that wood can be saved, thus increasing a utilization rate of the wood. The wood saved by a single piece of wood floor is limited, but many a little makes a mickle. Moreover, two adjacent floor bodies can be connected by the groove to reserve a certain gap therebetween according to need, which can increase the air permeability of the floor. The use of wood can be greatly saved to protect the ever-decreasing trees, and benefit the human society.

A panel splicing structure capable of repeated assembly and disassembly without damage and rapid splicing comprises a plurality of panels and a plurality of insertable locking plate structures. The panel is a hollow panel body. The panel is also provided with reinforcing support bars, insertion cavities and locking pin holes. The insertable locking plate structure comprises a hollow plate body, a plurality of locking pins and controlling rods. The locking pins protrude outside or retract inside the sides of the hollow plate body under control of the controlling rods. The panels are arranged side by side with each other. The insertable locking plate structures are inserted into the insertion cavities of the panels, and the locking pins are inserted into the locking pin holes by the controlling rods to assemble the panels to form an integrated panel.

Building panels, such as a floor or wall panels. The panels include a first mechanical locking system include a first locking strip at one of the third edge or fourth edge configured to cooperate for horizontal locking with a first locking groove at the other of the third or fourth edge of an adjacent building panel, preferably by means of a folding motion, and a second locking system including a second locking strip at one of the first edge or second edge, configured to cooperate for horizontal locking with a second locking groove at the other of the first or second edge of an adjacent building panel. The thickness of the second locking strip, in a thickness-direction of the building panel, exceeds the thickness of the first locking strip.

The invention relates to a building element in plate shape, in particular a floor covering panel, which, apart from a mineral carrier plate or a carrier plate of WPC, comprises an upper side wear layer as well as preferably a lower side levelling layer, as well as to a floor covering formed by using such building elements, and to a method for the arrangement thereof, wherein the side faces thereof comprise a non-locking profile for forming special joints for receiving a material for forming a connection element.
