A timber structural member includes: a first timber round having a first cooperating longitudinal surface, a second timber round having a second and a third cooperating longitudinal surfaces, and a third timber round having a fourth cooperating longitudinal surface. The first cooperating surface cooperates with the second cooperating surface, and the third cooperating surface cooperates with the fourth cooperating surface. The timber rounds are secured together to form a structurally integral unit in which the first cooperating surface is in contact with the second cooperating surface, and the third cooperating surface is in contact with the fourth cooperating surface, and the first, second and third timber rounds are substantially parallel to each other. The timber rounds are secured to each other by a plurality of spaced fasteners provided at acute and obtuse angles from a longitudinal axis of the structural member and extending through the timber rounds.

Embodiments of modular building units (blocks) are disclosed that can be stacked to provide insulating concrete forms (ICFs). The blocks are formed of a foamed polymer material, such as foamed polyurethane. The blocks, when assembled together in an ICF, are configured to form one or more vertical columns of concrete and one or more horizontal beams of concrete intersecting the one or more columns, in a manner of post and beam construction. The blocks can be tightly interlocked with other blocks in a construction process. The disclosed blocks can include significant interior space for rebar and concrete to be inserted to construct the structure. Molds and methods for producing modular units are also disclosed. The molds and methods enable rapid production and removal of modular building units from the molds. Methods of constructing structures using the modular building units are also disclosed.

A masonry block having chambers and cavities that form recesses in the block such that, when the blocks are laid on bond, re-bar may be inserted in horizontal and vertical directions for rectangular grid reinforcement, and the wall may be constructed without the use of mortar. The masonry block includes a stretcher block, end block, and a half-block and each block block has recesses for receiving insulation, re-bar, and/or a line pin.

A building panel includes an insulating member having a first surface and a second, opposing surface, and a first sheathing member secured to the first surface of the insulating member and including a coupling portion. The coupling portion has a recessed portion, a first extension portion adjacent the recessed portion, and a second extension portion on the opposite side of the recessed portion from the first extension portion. A sum of a width dimension of the first extension portion and a width dimension of the second extension portion is substantially equal to a width dimension of the recessed portion, and at least one side surface of the insulating member is substantially coplanar with a respective side surface of the first sheathing member.

Interlocking construction blocks of a type that can be used as part of a system for building various structures, such as walls. An individual block provides positive intermeshing with other blocks abutting thereto and positive interlocking with other blocks stacked thereon, forming a joint that allows the abutting blocks to be held together without the need for mortar. Interlocked blocks are capable of providing a barrier against horizontal water seepage along the joints from one side of the interlocked blocks to the opposite side. The blocks provide a relatively light-weight structural unit while still providing good structural strength against horizontal and vertical loads. The blocks may be formed at least partly of recycled waste material(s) and/or may themselves be made of materials that can be easily recycled, thereby providing an environmentally friendly construction material that may have a reduced carbon footprint compared to other construction block systems.

Embodiments relate to an enhanced method for building walls by primarily reducing the time for assembly. The design is for a molded multi-segment plastic composite construction block that interlocks horizontally, vertically and orthogonally with a clearance-fit, does not require mortar for structural integrity and is self-aligning. The blocks are molded out of natural-fiber reinforced thermoplastic composites with thermal expansion coefficient less than 0.0002 per degree Celsius and compression strength greater than 60 MPa.
