A concrete block system is provided and allows for the use of a single type of non-integral connector to perform different functions in a mortarless structure, the system comprising a plurality of structural concrete blocks and a plurality of veneer units. The same connector can be used to connect veneer units to structural blocks, to retain the veneer units in different orientations; to create near vertical installations or a setback between stacked rows of structural blocks. In addition, the system provides a single structural block, which can be used for both straight portions or corners of a same structure. The structural block can also be used to create double-sided walls, with opposite lateral walls being configured to received/retain veneer units thereon.

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.

An interlock connector interlocks building blocks that are assembled so as to provide a wall structure. The building blocks have respective front surfaces for defining a front façade of the wall structure and respective rear surfaces with at least one respective horizontal groove. The interlock connector comprises first and second bodies. The first body is inserted in the rear surface horizontal groove of a first building block. The second body is inserted in the rear surface horizontal groove of a second building block adjacent the first building block. Insertion of the first and second bodies in the respective rear surface horizontal grooves of the first and second building blocks provides for interlocking the first and second building blocks.

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.

Assembly of two construction elements (1) which each comprise a number of side faces and are provided with a connecting means (2) for connecting the construction elements (1) to one another. The construction elements each comprise a side face with a recess (3), the recess (3) having been produced by cutting away a part (4) from the construction element (1). The slidable parts (4) are slidable in the recesses (3) and form the connections (2). A method of connecting such construction elements (1) to one another is also provided.

A method and a module system for building purposes by using a module system is provided, said module system including a plurality of mutually equal-sized basic components, which are assembled for a wall structure in one or more vertical planes by installing the same in connection with each other side by side and on top of each other. The wall structure is put together from substantially thin-walled basic components, which are open at ends thereof opposite in a lengthwise direction thereof and have an open internal space, and which are coupled to each other side by side and on top of each other with connection pieces capable of being connected with a first form locking joint to lengthwise coupling arrangements present on each external side thereof. The basic components are coupled to each other with an end block interconnecting the basic components by the opposite ends thereof.

Embodiments of the present disclosure provide an apparatus for providing

an improved building block. The disclosure provides for a block made from recycled or new thermoplastic materials or other blend of materials. The new block design provides for geometric interlocking capabilities from block to block, layer to layer and wall to wall via an Interlocking Post and screws. This Post will not only mechanically interlock the block system but will as well mechanically hold the block in position via a metal screw.

A component having at least two parts which contact one another via their narrow faces, includes multiple connection elements which pretension the parts with respect to one another. The connection elements are accommodated in recesses formed as undercuts in the parts. The recesses are aligned transversely to the longitudinal extension of the narrow faces of the parts, the openings of the recesses being open towards the narrow faces of the parts. The connection elements are respectively formed of two wedge-shaped pieces arranged in a diametrically opposed manner. When the pieces of the connection elements are accommodated completely in the recesses, the ribs of the connection elements completely fill out the recesses, so that the parts are pretensioned with respect to one another, and a gap is prevented from forming between the parts or the closing of a previously present gap is achieved.
