The connector also includes a body arranged between the pair of sidewalls and defining a first gap between a first sidewall of the pair of sidewalls and the body and a second gap between a second sidewall of the pair of sidewalls and the body. The first gap is adapted to receive a first edge portion of a first layer of the structural insulated panel and the second gap is adapted to receive a second edge portion of the structural insulated panel. The connector further includes a pair of tongues extending substantially parallel to an outer surface of the base and defining a pair of channels therebetween.

An apparatus for connecting precast elements, wherein the apparatus includes a first part adapted for being cast into a first one of the precast elements, and the apparatus further includes a second part adapted for being cast into a second one of the precast elements, wherein the first part and the second part are arranged to receive a fastener for fastening the second precast element relative to the first precast element with the fastener crossing a joint between the precast elements at an angle to the joint.

A building panel is provided. The building panel includes an exterior wall portion, an interior wall portion, a pair of opposing sidewalls, a first end portion and an opposite second end portion. The pair of opposing sidewalls spacing apart the interior wall portion from the exterior wall portion to define a cavity therebetween. The exterior wall portion, the interior wall portion and the pair of opposing sidewalls are arcuate in shape to define the building panel. The first end portion has a slip lock slot extending between the pair of opposing sidewalls. The second end portion has a slip lock tab member extending between the pair of opposing sidewalls. The slip lock slot of the building panel is configured to receive the slip lock tab member of a second building panel to adjoin the first and second building panels in a continuous fashion.

A connector configured to couple plural wall elements like wall panels, the connector including a coupling including a first support that supports a locking hook that is pivotable from an idle position into an engagement position and movable into an interlocking position; a block including a locking bar that is arranged in a second support wherein the locking hook reaches behind the locking bar in the locking position; and a housing for the coupling or the block, the housing including a housing pass through opening wherein the locking hook passes through the housing pass through opening during a pivot movement from the idle position to the engagement position, wherein the housing includes a first housing half and a second housing half, wherein the housing pass through opening is closed by a cover wall against a pass through of the locking hook.

A protective enclosure for equipment located outside, such as, for example pipeline and wellhead valves, dewatering pumps, etc. includes a wall frame assembly constructed of a plurality of vertical frame members that are connected together at their tops and bottoms by a plurality of angle-iron members. Wall assemblies comprising insulated wall panels that are connected in a side-by-side relation by tongue-and-grove couplings are attached to the wall frame with the bottoms thereof supported on angle-iron members that connect the bottoms of the vertical frame members. A roof assembly can be attached to the wall frame in a stationary fashion or in a movable fashion to allow the roof to open, permitting access into the enclosure for servicing equipment housed therein. The enclosure has other features as described in the specification in further detail.

This invention relates to prefabricated, lightweight, multi-component structural modular building panels and modular building systems. The said panels are framed with edge members that have a unique connecting shape, making them modular. The multi-component panel allows for design flexibility and the mass manufacturing of its components. Connectors serve as a link to assemble the panels together, and to connect them to corners, floors or foundations, roof panels and the roof apex member, and or other conventional construction elements. Connectors and members, all with unique connecting shapes, coupled with the said panels, create a structural wall, roof, similar structure or building system. Assembled panels and members incorporate the primary building structure and the building envelope. The assembled panels, members and other components of the building system, in part or whole, can be flat packed for easy transport and shipping, and can be assembled quickly and easily with semi-skilled labor.

A modular panel is provided and includes a sill plate, a top plate, a plurality of vertical studs, and having at least one skin applied to a major face of the modular panel that presents a first edge having a waveform profile configured to connect to an opposing edge of an adjacent modular panel. At least one of the vertical studs is an end stud having a connector element configured to be secured to a complementing connector of the adjacent modular panel. Two or more of the modular panels may be connected together to form part of a shelter.

A building assembly includes a plurality of expanded polystyrene wall panels, headers, sill panels, U blocks, U block caps, roof panels, and connectors. Each U block includes rebar and at least one of concrete and cementitious material in a recess or void therein. Each U block cap when joined to the U block creates an enclosed void in the U block which holds the rebar and concrete and/or cementitious material. A plurality of capped U blocks joins a plurality of wall panels, headers, and sills to form a wall structure. A plurality of U blocks are placed on a top surface of the wall structure. A roof assembly including a plurality of U blocks, H connectors, T connectors, and combinations thereof connected to roof panels to form a rigid roof assembly. A coating of cementitious material provides additional structural rigidity and resistance to impact, fire, water, mold, mildew, and insects.

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 insulating barrier of a panel including has a first stratum and a second stratum, each having a plurality of ridges that face each other, and run athwart of each other. Clearance between at least some adjacent pairs of the ridges provide a mechanical chase that reaches across at least most of the panel. A cladding overlaying at least one side of the insulating barrier is denser than the barrier. The mechanical chase is in the form of a groove through which a utility feed can be routed when the panel is to be mounted in a building.
