The modular anti-ballistic shelter system includes two end units and, optionally, additional middle units for a wider structure. End and middle units may also stack atop each other for multi-story structures. Each unit is configured to comply with both ISO standards for size and weight, and with the U.S. Department of State Certification Standard for Forced Entry and Ballistic Resistance of Structural Systems. Each exterior wall of each end unit and each middle unit is reinforced with wall studs that penetrate the unit's structural framework of beams and frames. Even though these wall studs are welded into place, penetration of the wall studs into the beams and frames ensures acceptable blast, ballistic, and forced entry resistance even if the welds are flawed.

A system for providing an angled construction or bent beam construction. Such system may include a first beam comprising a first elongated beam segment having a first interlocking joint portion at one end, and a second beam comprising a second elongated beam segment having a second interlocking joint at one end, wherein the first interlocking joint portion is configured to rotatably couple to the second interlocking joint to form a rotatable joint such that the angle between the first beam and the second beam is adjustable.

A strut-and-node truss design that is applicable to all space frame structure designs can be made with using robotic (semi-autonomous and/or fully autonomous) or telerobotic assembly/joining. Nodes can include a 2-dimensional weld path in an effort to reduce the complexity of having to weld in 3-dimensions. Furthermore, each strut to node connection can be concentrated in a small area where each weld can be performed robotically from a fixed position that only requires the robotic weld head to swivel in a small operating window to reach each joint.

The invention relates to panelized system for a structure. The panelized system typically comprises a plurality of joists structured to be operatively coupled to one or more support members of the structure. Each of the plurality of joists are associated with a joist seat comprising a toe and one or more joist apertures. Typically, at least one or more of a plurality of joist seats are operatively coupled to the one or more support members using a toe weld between the toe and the one or more support members. However, an aperture weld between the one or more joist apertures and the support members is omitted. Moreover, a fastener between the one or more joist apertures and the support members is also omitted.

The present application provides a prefabricated structural system and an assembly method thereof. The prefabricated structural system may be applied to steel structures, reinforced concrete structures and timber structures. When applied to the steel structures, the prefabricated structural system includes a plurality of steel structure joints and related members. The steel structure joints and related members further comprise: a beam-column connecting sleeve, comprising a first box-shaped steel tube and first C-shaped sleeves extending from and perpendicular to outer surfaces of the first box-shaped steel tube, wherein the first C-shaped sleeve is provided with first wedge shaped recesses at ends of upper and lower flanges thereof; columns, having a column connecting end inserted into the first box-shaped steel tube; main beams, having a main beam connecting end inserted into the first C-shaped sleeve; and main beam fixing steel plates, provided with first wedge shaped protrusions that are tenon-mortise-jointed with first wedge shaped recesses at both sides of the first C-shaped sleeve. In addition to the steel structural construction, the beam-column connecting sleeve of the prefabricated structural system may be further extended to reinforced concrete structures and timber structures.

Each exterior wall of each end unit and each middle unit is reinforced with wall studs that penetrate the unit's structural framework of beams and frames. Even though these wall studs are welded into place, penetration of the wall studs into the beams and frames ensures acceptable blast, ballistic, and forced entry resistance even if the welds are flawed.

An I-beam support system for aligning and leveling an I-beam during installation on a ground surface. wherein the I-beam support system comprises two sides, a hinge assembly and a fastener assembly. The two sides comprise a first side and a second side. each among the two sides comprises a beam clamp arm, a clamp arm hinge, a vertical support assembly, and a lower support assembly. The lower support assembly is configured to support the vertical support assembly on the ground surface. The I-beam support system is configured to selectively transition between a closed configuration and an open configuration. The closed configuration comprises the fastener assembly holding the two sides around a portion of the I-beam. The open configuration comprises the two sides unconnected at a distal end of the beam clamp arm. each among the vertical support assembly comprise an upper end adjusting support.

An apparatus, such as a beam pocket, connects a beam to a wall, such as a concrete wall. The apparatus includes a frame having a plurality of panels that cooperate to define a pocket of various heights. The apparatus includes a clamp within the pocket. The clamp is configured to secure an end of the beam at a position within the pocket. The clamp is further configured to selectively define the position relative to the frame. The apparatus further includes at least one anchor extending from the clamp and away from the pocket for mounting with the wall.
