A solid reinforced concrete column and a method of constructing the same are disclosed. The solid reinforced concrete column includes outer main reinforcing bars, inner reinforcing bars, inner transverse reinforcing bars, outer transverse reinforcing bars, and concrete. The outer main reinforcing bars are arranged in an axial direction. The inner reinforcing bars are each arranged to be placed between two or three of the outer main reinforcing bars inside the two or three outer main reinforcing bars in the axial direction. The inner transverse reinforcing bars are each arranged to connect the two or three outer main reinforcing bars and the inner reinforcing bar in a transverse direction. The outer transverse reinforcing bars are arranged to surround the outer main reinforcing bars outside the outer main reinforcing bars in the transverse direction. The concrete is placed to bury the reinforcing bars.

An anchoring member (15) capable of being integrated into a facing element (10) for the creation of stabilised 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 stabilising member for stabilised earth structures, such as a strip or similar, can be made to pass around it by inserting it into the mouth (13).

An erection system for one or more elongated elements, such as structural columns, pre-fabricated reinforcing cages or tower-like structures includes one or more longitudinal lifting bars running parallel with the elongated element's longitudinal direction. The lifting bars are installed within or onto the elongated element through apertures in the element's upper and lower support pieces. A rigging system supports the upper portion of the lifting bar. The lifting bar's lower portion includes external threading to receive an internally threaded load bearing nut. The load bearing nut supports the elongated element's weight onto the lifting bar's lower portion. The upper and lower support pieces stabilize the elongated element with lateral restraint. Removing the load bearing nut and raising the lifting bar up through the support piece's apertures extracts the lifting bar from the elongated element. Adjustable spreader bars separate multiple lifting bars to minimize lateral and bending stresses in the lifting bar.

A connection between a hoist and a structural panel, wherein a clip connects a sling of the hoist to the structural panel, and the clip includes a plate portion having an eye opening receiving the sling. The clip also includes a tongue portion extending from the plate portion, the plate portion lying in registration with the attachment surface of one or more structural member that form part of the structural panel. Fasteners connect the tongue portion of the clip to the attachment surface of the structural member.

There is disclosed a lifting attachment for a building unit comprising sheeting and a support structure over which the sheeting is disposed, the attachment being configured such that it can be connected to or integrated into the support structure and comprising a lifting anchor that, when the attachment is so connected or integrated, is engageable by a component for lifting the unit such that a releasable interconnection between the component and the support structure passes through an opening in the sheeting.

A lift nut mounting bracket for hoisting a building wall panel is provided. The lift nut mounting bracket includes a side plate and a top plate connected to the side plate at a first joint. The top plate includes a first opening therein. A receiving plate is connected to the top plate at a second joint. A receiver is formed in the receiving plate and is aligned with the first opening in the top plate. A nut is received and retained in the receiver. A plug may be inserted into the nut. A method of manufacturing a lift nut mounting bracket is also provided.

Concrete coupling assembly comprises a base holder for being attached to a concrete forming surface, the base holder including a central opening; a coupler having one end disposed within the central opening, the coupler having an axis for being positioned substantially transverse to the forming surface, the coupler having first and second threaded bores through the one end for attachment of a threaded rod; and a separate anchor body threadedly attached to another end of the coupler.

A method of installing a vaporizer in a remote manufacturing yard is provided. The method can include the steps of obtaining a lower stage and an upper stage of a vaporizer; obtaining a first column section and a second column section; installing the lower stage to a bottom head such that the lower stage is in fluid communication with an inner volume of the bottom head; installing the first column section over and around the lower stage and fitting and welding a bottom of the first column section to the bottom head; installing the upper stage; and installing the second column section and fitting and welding a bottom of the second course to the first course.

A system for handling various structural building components including a pick and stack-registry lug which is anchorable to the top of a building component for handling that component in either one, or both sequentially, of its two, pick and stack-registry functional modes, (b) a clamshell-style, releasably lockable clasp adapted to receive and close capturingly upon the lug under operational circumstances with the lug anchored to the top of a building component, and ready to function in its pick category of component-handling behavior, and (c) a guide socket includable in the base of a building component functional for camming, guided reception of a lug with the lug then functioning in its stack-registry mode of behavior to facilitate overhead stack registering of two building components in relation to the lowering of an overhead component onto the top of an underlying component whose top also has a lug anchored to it.
