There is provided herein a modular be fabricated wall system which has a number of interlocking modular prefabricated wall sections. Each wall section has opposing planar face boards and a number of orthogonal spacers adhered to respective inner faces of the face boards for bracing the face boards apart. Vertical joiners may be adhered to inner edges of each face board for quickly and easily vertically slotting together adjacent wall sections in a row. The present wall sections are low-cost in that both the face boards and the orthogonal spacers may be cut from low-cost board, such as fibre cement board. Specifically, the face boards and the spacers may be both made from fibre cement board and the spacers may be glued perpendicularly between inner surfaces of the face boards. As such, the present wall sections may be manufactured without fasteners, ties and the like.

A modular partition system comprises a plurality of panels and at least one connecting strip. Each of the plurality of panels comprises two support members extending generally perpendicularly to a plane of the modular partition system and a central panel extending between said two support panels. The plurality of panels are arranged such that the central panels of each of the plurality of panels are generally mutually parallel and one support member of each of the plurality of panels is adjacent to a support member of an adjacent panel. The at least one connecting strip cooperates with a support member from each of two of the plurality of adjacent panels so as to connect said two of the plurality of adjacent panels.

A wastewater evaporative separation system can include an evaporation panel assembly and a wastewater delivery system. The evaporative panel assembly can include at least 10 individual evaporation panels laterally joined together and fluidly coupled to a body of wastewater. The evaporation panel assembly can be configured for receiving wastewater from the body of wastewater and evaporating water therefrom as the wastewater cascades down the evaporation panel assembly and contaminants generally become more concentrated. The wastewater delivery system can be associated with the body of wastewater and can include a fluid directing assembly delivering wastewater from the body of wastewater to an upper portion of the evaporation panel assembly.

The present disclosure evaporation panel systems including a plurality of evaporation panels. The evaporation panels can include a plurality of evaporation shelves that are laterally elongated, vertically stacked, spaced apart from one another, and horizontally oriented; and a plurality of vertical support columns positioned laterally along the plurality of evaporation shelves to provide support and separation to the plurality of evaporation shelves. The evaporation panels can also include a plurality of female-receiving openings which are individually bordered by two evaporation shelves and two support columns; and a plurality of male connectors positioned at lateral ends of both the first evaporation panel and the second evaporation panels. The first evaporation panel and the second evaporation panel can be orthogonally connectable via the male connectors of the first evaporation panel and the female-receiving openings of the second evaporation panel.

A method for forming three-dimensional (3D) printed structures is disclosed. The method may include 3D printing a first structural member including an opening to a cavity inside the first structural member; and 3D printing a second structural member including a protrusion disposed within the opening and the cavity of the first structural member.

The present subject matter discloses an outdoor storage shed utilizing molded plastic components or panels. A storage shed structure can comprise foldable corner panels and one or more interlocked teeth couplings. The foldable corner panel can pivot at integrated folding grooves to serve as corners. The interlocked teeth couplings comprise a plurality of protrusions and matched recesses arranged on both sides of engaged panels. Furthermore, the storage shed can come with pre-constructed shelf grooves in the foldable corner panels. The storage shed can have a concaved door frame and a recessed door.

The invention is a system and method for building a polar zonohedron structure from precast cement panels. The building system may include a plurality of panels configured to register with each other. Each panel includes a precast cement base with side walls enclosing a cavity within the precast cement base. The panels include at least one ridge protruding from at least one surface of a side wall of the panel and at least one aperture on at least one surface of a side wall of the panel. Each ridge is preferable configured to interlock with each aperture; in his way, the panels interlock with each other to form the polar zonohedron structure.

A stay-in-place form comprises a plurality of elongated panels connectable to one another in edge-to-edge relationship. The plurality of panels comprises first and second panels connectable to one another in edge-adjacent relationship by a connection which comprises a contact joint. The first panel comprise a longitudinally extending first seal-retaining projection shaped to project outwardly from the outer surface of the first panel at a location spaced apart from a first outer-surface transverse edge of the first panel in a first transverse direction. The second panel comprising a longitudinally extending second seal-retaining projection shaped to project outwardly from the outer surface of the second panel at a location spaced apart from a second outer-surface transverse edge of the second panel in a second transverse direction opposite the first transverse direction. The first and second seal-retaining projections and the outer surfaces of the first and second panels defining at least a portion of a seal-receiving concavity which opens outwardly from the form when the connection is made.

Evaporation panel securing system can include first and second evaporation panels, and a security fastener to secure a male connector (first evaporation panel) within a female-receiving opening (second evaporation panel) in an orthogonally joined orientation, for example. The evaporation panels can include a plurality of evaporation shelves that are laterally elongated, vertically stacked, spaced apart from one another, and horizontally oriented; a plurality of vertical support columns positioned laterally along the plurality of evaporation shelves to provide support and separation to the plurality of evaporation shelves; a plurality of female-receiving openings individually bordered by two evaporation shelves and two support columns; and a plurality of male connectors positioned laterally at ends of the plurality of evaporation panels, wherein the male connectors of the first evaporation panel are releasably joinable with female-receiving openings of the second evaporation panel.
