The present invention relates to the reuse of otherwise discarded plastic to be used as building material and is resistant to extreme weather conditions. A building block comprises a multiple sided hollow box, wherein the sides of the box are tapered, with at least one keyway respectively slotted on at least two faces of the hollow box and an interlocking key which has a corresponding shape with the keyway to tightly interlock in the keyway.

A building system comprising at least one block of claim 1 and further including at least one mortarless side panel including a finished outside surface and at least one dovetail protrusion on an opposing surface for joining the side panel to the at least one blocks, and a connector on each end of the panel for joining the side panel to other side panels, and at least one top cap including a finished top surface.

A block and various block assemblies are disclosed. The block has at least one side including one or more tapered slots. Each of the slots has one or more apertures. The at least one side has a bottom end comprising at least one footing and a top end comprising a groove. Blocks are stacked by fitting the footing of one block into the groove of another block. A block assembly comprises a first block, a second block, a double key, and connector tubes. The first block is connected to the second block using the double key, which is inserted into a slot on each of the blocks. A connector tube is threaded through apertures on the slots and the double key.

The present disclosure provides a building block (100) that is designed to hold utilities, including but not limited to, electricity and plumbing. The building block (100) of the present disclosure can resist compression forces and moment and can connect to other building blocks (100) to form a modular wall system with the ability to distribute the forces in a way that reduces the stresses on each individual block. The building block (100) of the present disclosure may include a body with an upper end (11) and a lower end (10), one or more main compartments (16, 17), and one or more inner pass-through openings (19), wherein the upper end (11) comprises a first upper cut (13), a second upper cut (14), and one or more protrusions (18), and the lower end (10) comprises a first lower cut (12) and one or more slots (110). The present disclosure also provides a building system including more than one multi-purpose building blocks (100) and a base (2).

A building system comprising at least one block of claim 1 and further including at least one mortarless side panel including a finished outside surface and at least one dovetail protrusion on an opposing surface for joining the side panel to the at least one blocks, and a connector on each end of the panel for joining the side panel to other side panels, and at least one top cap including a finished top surface.

A set of interlocking blocks consists a plurality of first blocks and a plurality of second blocks capable of forming kinematic interlock. Each of the first blocks and second blocks comprise at least one male joint and female joint for mating with its counterpart. The motion of the first blocks and second blocks are constrained by joints. Subsequent first blocks and/or second blocks reinforce and immobilize prior first blocks and/or second blocks. Assembly of an interlock structure consisting the set of interlocking blocks may be performed via translation motions.

A modular block with four walls, a top face and two internal cavities, where both the locking and the centralization between the blocks are prominently made by male and female wedge-like couplings.

A building system including at least one block and further including at least one mortarless side panel including a finished outside surface and at least one dovetail protrusion on an opposing surface for joining the side panel to the at least one blocks, and a connector on each end of the panel for joining the side panel to other side panels, and at least one top cap including a finished top surface.

A fixing device for mounting wall elements for constructing a wall, includes: a support profile, A securing element which is designed to extend between the wall elements and can be twisted relative to the support profile between a first position in which an engagement element of the securing element remains separate from the support profile, and a second position in which the engagement element engages on the support profile for fixing and secures the wall elements; and a closing profile which in the second position is attachable to the securing element and comprises a blocking element for preventing the securing element from twisting back.
