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.

There is provided building structures that are demountable from a first configuration to be reassemblable to the first configuration or another configuration. The building structures include systems and kits for the structure, post anchors, kits for floor structure, method for assembling floor structures, wall and ceiling support systems, electrical junction box supports, and kits for frame assembly.

An improved steel stud wall panel which includes a diagonal member able to be placed under tension during installation. The diagonal tension imparts rigidity to the wall panel, preventing warp.

A light steel roof truss with a structure of a double continuous beam includes structural beams (1) and structural columns (2). The structural beam (1) consists of a pair of continuous beams, and the structural column (2) is located between the two continuous beams through locating holes (4). Thereby the stability of a support structure of the roof truss is increased, and the supporting members of the roof truss can be connected conveniently.

Disclosed is an exterior wall (17) for a building (11). The exterior wall (17) comprises an inner wall (20) including a load-bearing structure formed by a transversal roof metal profile (14) and a transversal foundation metal profile (13) between which a number of intermediate metal profiles (15) extend, and wherein an inside surface (59) of the inner wall (20) is provided inner sheathing (63). The exterior wall (17) also comprises an outer wall (21) including a load-bearing structure formed by a transversal roof metal profile (14) and a transversal foundation metal profile (13) between which a number of intermediate metal profiles (15) extend, and wherein an outside surface (64) of the outer wall (21) is provided outer sheathing (62). The inner wall (20) and the outer wall (21) are mutually fixed at the transversal metal roof profiles (13) and the transversal metal foundation profiles(14) so that a cavity (34) is formed between the inner wall (20) and the outer wall (21). A method for constructing an exterior wall (17) of a building (11) is also disclosed.

A building structure including a first building member and a second building member may be connected by a plurality of fasteners, each fastener having a head, a threaded portion having a through hardness of between HRB 70 and HRC 40, a thread-forming portion of at least HRC 50 hardness enabling the fastener to form threads in at least the second steel building member, and a fluted lead portion of at least HRC 50 hardness with a nominal diameter between 70 and 95% of major diameter, such that the fastener is capable of providing a ratio of strip torque to thread-forming torque of at least 3.0 and a ratio of strip torque to drive torque greater than 6.0 when the second steel building member having a thickness of 0.25 inch and the fluted lead portion having at least one diameter within nominal diameter between 80 and 98% of major diameter.

Building structures can be fabricated at an offsite, and then assembled at the construction site. The building structures can include beams and wall panels having metal attachments. The beams and wall panels can be assembled by coupling the metal attachments, for example, by welding.

There is provided a prefabricated floor panel (101) for use with a supporting structure (103) including a floor member (105) the floor member (105) defining a floor surface (107) and being adapted to engage with an adjacent similar floor panel (101) and at least one or more strengthening beams (109) configured to engage with the supporting structure (103) in use to support the prefabricated floor panel (101).

A truss clamp assembly includes a lower support member extending in a lateral direction, a vertical rod coupled to the lower support member and extending in a vertical direction that is transverse to the lateral direction, a first engagement portion coupled to the vertical rod and spaced apart from the lower support member in the vertical direction, and a second engagement portion coupled to the vertical rod and spaced apart from the lower support member in the vertical direction, where the second engagement portion is spaced apart from the first engagement portion in the lateral direction, such that the first engagement portion and the second engagement portion define a gap positioned between the first engagement portion and the second engagement portion in the lateral direction.

A support column extends in a longitudinal dimension and includes a plurality of outer hollow longitudinal structures. Each longitudinal structure defines an interior passage extending along a length of the longitudinal structure. The support column includes a plurality of inner members. The plurality of outer hollow longitudinal structures are aligned end-to-end along a single axis. The interior passages of the plurality of outer hollow longitudinal structures cooperate to define an interior passage of the support column. The inner members are aligned end-to-end along the single axis within the interior passage of the support column so that opposed longitudinal ends of each of the inner members extend to respective longitudinal ends of each adjacent inner member. At least one end of at least one inner member is longitudinally offset from every longitudinal end of the plurality of outer hollow longitudinal structures.
