A beam-column node structure of the steel prefabricated building is provided. The structure includes inner sleeves and driving components. The inner sleeves are slidably embedded in the transverse sleeves of the cross beam or node member; the driving components are used to drive the inner sleeves to move from one of the cross beams and the transverse sleeves embedded with the inner sleeves to the other. The inner sleeves are partly located in the crossbeams and partly in the lateral sleeves, and then the internal connection between the crossbeams and the lateral sleeves can be realized by the fasteners.

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 clip (2) for fitting between a first component (6) and a second component (4) in a building structure, the clip including a first member (8), a second member (10) and a connecting portion (12) connecting the first member (8) to the second member (10); the first member (8), the second member (10) and the connecting portion (12) forming a space (38) in which a portion of a leg (18) of the second component (4) is adapted to reside; the first member (8) and the second member (10) adapted for engagement with the portion of the leg (18) of the second component (4).

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.

There is disclosed a modular platform assembly including a plurality of legs (18), a plurality of floor beams (20a,b,c), and a plurality of connectors (24a,b,c,d) for connecting the legs (18) and the floor beams (20a,b,c). Each said connector (24a,b,c,d) comprises: a downwardly open blind recess (59) with a closed top end (60) and an open bottom end (62); and an upwardly open blind recess (64) with a closed bottom end (66) and an open top end (68). The legs (18) are mounted into the downwardly open blind recesses (59) of the connectors (24a,b,c,d) and the floor beams (20a,b,c) are mounted into the upwardly open blind recesses (64) of the connectors (24a,b,c,d) such that the legs (18) extend downwardly from the floor beams (20a,b,c).

A beam-column node structure of the steel prefabricated building is provided. The structure includes inner sleeves and driving components. The inner sleeves are slidably embedded in the transverse sleeves of the cross beam or node member; the driving components are used to drive the inner sleeves to move from one of the cross beams and the transverse sleeves embedded with the inner sleeves to the other. The inner sleeves are partly located in the crossbeams and partly in the lateral sleeves, and then the internal connection between the crossbeams and the lateral sleeves can be realized by the fasteners.

A structural connector comprising at least one spigot and at least one socket wherein at least a portion of the at least one spigot is tapered and at least a portion of the at least one socket is a complimentary tapered configuration.

A connector includes a first body, a second body, a first fastener, and a second fastener. The first body has a base portion and a protrusion, the protrusion extends away from the base portion along a first direction, and the first body has a first cavity that extends into the protrusion and towards the base portion along the first direction. The second body has a second cavity, which is shaped to receive the protrusion such that rotation of the first body relative to the second body is blocked. The connector may be used to attach structural members, for example during the construction of a modular structure.

A beam system for a screened enclosure that includes one piece support beams having an internal channel and three or more spline grooves on one or more exterior sides. The spline grooves are designed to accept and secure screen material. Inserts positionable within the interior channel of adjacent beams may provide increased structural support for larger openings in the screened enclosure. The inserts generally include a central pillar having angular caps attached to opposing lateral edges thereof so that an insert fits snugly within the interior channel of the support beam. The inserts may be secured within the support beams by fastening elements.

A multistory building construction system comprising at least one base plate comprising a centrally disposed sleeve extending vertically from a top surface thereof and configured to engage an interior portion of a bottom end of at least one first-floor column comprising a cap plate disposed on a top end thereof with a centrally disposed sleeve extending vertically therefrom configured to engage an exterior portion of a bottom end of at least one upper-floor column and configured to support a decking for a concrete floor and configured so that a top end of the sleeve may be used as a benchmark for pouring the concrete floor, the first-floor column and the upper-floor column further comprising at least one sheer tab for attachment of beams for support of the decking.
