A rail assembly is provided, suitable for embedding in concrete, including a profile rail having a rail body, wherein the rail body has a first lateral wall, a second lateral wall, a first rail lip protruding from the first lateral wall, and a second rail lip protruding from the second lateral wall. The rail assembly has a reinforcing element with a force-absorbing body, wherein the force-absorbing body is positioned in front of the first lateral wall of the profile rail for contacting the first lateral wall of the profile rail with the force-absorbing body. A construction body having a concrete element, in which a rail assembly of this type is embedded is also provided, as is a method.

A system including an insert including a body defining an inner cavity at a first end thereof. The insert includes an anchor having an opening formed therein, and the opening of the anchor is positioned in the inner cavity of the insert. The system further includes a spacer having a first end that is couplable to a second end of the insert to thereby adjust a height of the insert. The spacer is configured to be coupled to another spacer at a second end of the spacer.

A connector assembly, having an upper connector, a pin coupling the upper connector to a lower connector and a gusset plate sandwiched between the upper and lower connectors. Also, disclosed is a hoistable connector assembly, a lifting frame assembly, a coupling system for modular frame units, a method for assembling a module unit using the connector assembly, and a modular frame unit and building having the connector assembly.

Provided herein is an assembly for carrying or supporting a load. The assembly comprises a plurality of members connectable in an assembled arrangement for carrying or supporting the load. Each member comprises a first end and a second end, at least one of the first end and the second end has a pair of connecting members comprising two lugs that each has defined therein two holes. The lugs are configured for alignment with a corresponding pair of lugs formed on another member in the assembly. Fasteners extend through the holes formed in the lugs when the holes are aligned. Further provided are members for use in the assembly and connector elements for attaching two or more members in the assembly.

A handrail includes a support assembly for attachment to a concrete slab having an upper surface with attachment formations anchored at the upper surface. The assembly includes a handrail support component and a connector component. The connector component is attachable to the support component and an attachment formation. The support and connector components can be tightened to each other to tighten the connector component to the attachment formation for tightening the support component onto the slab. The invention extends to a handrail system including the slab, and to a method of installing handrail components on the slab.

A cast-in-place concrete anchor assembly for installation in or on a metal decking form. The assembly incudes an anchor housing with shaft extending from a flange. The flange includes a locking member that may take the form of a female thread. The anchor assembly also including an anchor support for receiving a shaft of the anchor housing. The anchor support further includes a radial expansion member with a tapered surface. The radial expansion member flexes outward upon engagement of the tapered surface by the shaft to expend the expansion member. The expansion member expanding outwardly past an outermost radius of a hole in the metal decking to lockably and selectively connect the assembly to the metal decking.

A variety of storage structures may be constructed onsite entirely from pre-fabricated parts reducing labor and time required for assembly.

An anchoring member (15) capable of being integrated into a facing element (10) for the creation of stabilized earth structures, comprising a shell (21) that defines a recess (18) with a mouth (13). An anchoring bar (20) extends transversely within the recess (18) in such a way that, in use, an elongated stabilizing member for stabilized earth structures, such as a strip or similar, can be made to pass around it by inserting it into the mouth (13).

A lifting device for erecting a structure having splice plates is provided. The lifting device having a body adapted to engage the splice plates and having an attachment site adapted to be coupled to a hoisting apparatus. The body further has an opening defined therethrough and adapted to align with the plate openings. The lifting device also has a connection assembly comprising a support structure connected to the body and having a cradle, and a releasable connector adapted to extend through the plate openings and the opening. The cradle is adapted to secure the releasable connector through the splice plates and the body when the body is lifted via the hoisting apparatus. The connection assembly also has a disconnection mechanism operable from a ground surface to remove the releasable connector from the plate openings and the opening to disconnect the body and the structure.

The present disclosure is directed to embodiments of a tower structure with at least partially additively manufactured, stacked tower sections. Embodiments of the tower structure have a plurality of stacked tower sections, wherein at least one tower section of the plurality of stacked tower sections includes a wall element having one or more printed layers, and a base holding thereon the one or more printed layers. The present disclosure also is directed to a method of manufacturing a tower structure using a stacked tower sections and additive manufacturing. Embodiments of the method include forming a base of poured concrete or cast material, printing and depositing one or more printed layers to form a wall element, and stacking the plurality of tower sections to form the tower structure.
