The present disclosure relates to the building industry and in particular to a block for use in automated building construction. In one aspect, the block comprises a generally cuboid body having a top and a base, a length extending between a pair of opposed ends, and a width extending between a pair of opposed sides; the body including a plurality of hollow cores extending from said top to said base, and arranged in a row between said opposed ends; wherein each core has a rectilinear cross-sectional shape; and wherein the thickness of the block between each pair of adjacent cores is at least double the thickness of the block on all other sides of each core, so that the block is divisible into a plurality of substantially identical block portions, each portion including four walls of substantially uniform wall thickness about its core.

The current invention concerns a covering, such as a floor covering, wall covering or ceiling covering, said covering comprising a surface layer, and a substrate layer attached to said surface layer, said substrate layer optionally comprising one or more reinforced thermoplastic layers. Said covering further comprises a backing layer on the bottom side of said substrate layer, opposite to said surface layer, and a textile layer attached to the bottom side of said backing layer, optionally through a contact layer. The covering further comprises a coating applied to the bottom of said textile layer. The invention also provides a method for producing a covering, such as a floor covering, wall covering or ceiling covering.

A hard synthetic rubber construction block system that includes: a top block; a plurality of square-shaped cavities on the under side of the top block; a bottom block; a plurality of square shaped studs on the upper side of the bottom block that insert into the plurality of square cavities in the top block, binding them together. Other features of the construction block system include: a horizontal insert on each side of the upper portion of the lower block spanning its length; a matching V-groove inside the lower portion of the upper block whereby the described insert of the lower block snaps into it, creating a locking point. Further, tongue and groove connections are at each end of the blocks whereby the tongue feature on one end of a block slides into the groove feature of an adjoining block, locking them horizontally.

The invention is about a modular foldable brick that enables architectural elements such as stacked walls, arches, corners, doors, windows and wall niches to be constructed at indoor and outdoor conditions that divides, restricts and secures a certain space; Due to the possibility of folding the storing and carrying of this brick is possible at a minimum weight. The brick is connectable within itself and also attachable to others for constructing architectural elements as wall building systems. The foldable brick provides a foldable brick body that forms the outer walls and an inner wall being formed with three techniques; connecting/fixing (A-B groups)/encircling (C group). All three techniques are related to the forming of the detachable wall building system's entity unit foldable and sustainable brick. All these three techniques are used simultaneously.

In one embodiment, an article of manufacture includes a plurality of nestable, identically sized building blocks, each block having at least one inward-slanting side wall connected to a top surface of the block at an edge of the block, wherein a first block defines a hollow interior space adapted to receive a second block in a nested configuration. One or more of the blocks have one or more recesses on the top surface that are each designed to receive a portion of the bottom edge of another block, thereby providing increased stability for non-nested configurations. A recess may have a curved shape that can receive a curved portion of another block at different angular orientations of the blocks. The recesses may engage another block's bottom edge in a non-interlocking manner or in an interlocking manner.
