A dovetailed building block includes a block body having a plurality of side surfaces. The side surfaces are constructed in an order of having a side surface with a dovetailed recess next to another surface with a dovetailed projection. The dovetailed projection of one said block body can engage the corresponding dovetailed recess of another said block body in a 90-degree cross manner. Thereupon, while in stacking a plurality of the block bodies, variety of secured and stable three-dimensional curved configuration can be built through angular engagement of one dovetailed projection of one block body and another dovetailed recess of another block body.

An insulated siding sheet includes an integrated insulation material and a plank siding. The integrated insulation material includes: (i) a back side; (ii) a front side opposite the back side; (iii) a top horizontal edge having a 45 degree angle; and (iv) a bottom horizontal edge having a 45 degree angle, in which the back side of the integrated insulation material has vertical grooves that extend from the top horizontal edge to the bottom horizontal edge. The plank siding is attached to the front side of the integrated insulation material. The plank siding includes a top horizontal edge and a bottom horizontal edge that both have a portion of the plank siding cut-away to overlap with horizontal edges of adjacent insulated siding sheets. An insulated siding sheet system and a building having the insulated siding sheet system is also included.

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.

A removable connector used for connecting two or more wall panels. The connector is accessible to a user in a vertical space between the connected wall panels open to both front face and rear face of each panel. The user is able to easily engage and move the connector, relative to the wall panels, to latch and unlatch the connector with a view to connecting and disconnect the panels.

Method of making construction materials intended for use as structural elements, such as structural blocks, used in the construction of buildings and civil engineering structures. In one aspect, the blocks may comprise a body shape configured so as to allow it to interlock with other blocks in the construction of a structure. Methods for manufacturing the blocks and structures comprising such materials and methods for building such structures are also disclosed.

A massive block preferably made of compressed earth is described as well as a method to build walls utilizing the massive blocks. By combining wooden frame construction and massive wall construction with bricks or other massive block elements, a wall can be built with the advantages of both. A wooden stud frame is erected, the electricity and other utilities are placed through the frame and then the frame is covered up on both sides with large massive blocks of a specific design that interlock with both the frame and each other. The cavities in between the blocks can then be filled up with a filler such as sand to create additional thermal mass and improve the sound insulation properties of the wall. A second embodiment of the wall utilizes an extra layer of blocks with grooves to accommodate a radiant heating system and insulation material.
