A prop head assembly is configured to be fixedly connected to a vertically-extending construction column, and also configured to support a horizontal construction beam assembly once the prop head assembly is fixedly connected to the vertically-extending construction column The prop head assembly includes a first beam-locating feature and a second beam-locating feature. The first beam-locating feature is configured to selectively receive, at least in part, a beam-reference portion. The second beam-locating feature is also configured to receive the beam-reference portion once the beam-reference portion is inadvertently displaced away from the first beam-locating feature and from the vertically-extending construction column and toward the second beam-locating feature.

The disclosure presents a composite concrete structure formwork which comprises stay in place fiberglass profiles and reinforcement to form various building and shelter structures. The structures include an interior container maintained at a set distance within an exterior container to form a void. The void is filled with wet concrete which is allowed to cure. All of the components in a preferred embodiment are formed of a fiberglass material.

The disclosure presents a reconfigurable composite floor formwork which defined by a plurality of interlocking fiberglass panels formed into profiles which may be moved and adapted to provide a concrete form for a floor or ceiling. All of the components in a preferred embodiment are formed of a fiberglass material.

Disclosed herein is a clamp for interconnecting two components of a support apparatus such as components of a shoring apparatus for concrete forming systems. A clamp member having a moveable jaw is received for pivotal movement in a housing that is secured to one of the components. A plurality of flutes disposed at an angle to the pivot axis of the clamp member are received in coacting recesses in the housing and a proximal cap maintains the desired position of the clamp member within the housing. Axial movement of the clamp member will pivot the swing arm and a coacting, moveable jaw toward a fixed jaw formed in the housing to releasably secure the clamp to the other component.

A safety device for securing a person to a floor panel of a shuttering system. A base element secures a safety post. The base element can be placed on a floor panel of a shuttering system. The safety post has a personal safety element, to which the person can be selectively secured. A securing mechanism has a securing carrier, on which at least one engaging element is arranged, wherein the securing carrier is coupled to the base element. The engaging element can be adjusted into a securing position and a release position, wherein the engaging element can be engaged with the shuttering system in the securing position in order to fix the base element to the floor panel, and wherein the engaging element can be decoupled from the shuttering system in the release position in order to decouple the base element from the floor panel.

Apparatus is provided for vertically-extending construction column and horizontal construction beam assembly having beam-reference portion. Apparatus includes prop head assembly configured to be fixedly connected to vertically-extending construction column, and also configured to support horizontal construction beam assembly once the prop head assembly is fixedly connected to vertically-extending construction column. Prop head assembly includes first beam-locating feature and second beam-locating feature. First beam-locating feature configured to selectively receive, at least in part, the beam-reference portion. Second beam-locating feature configured to selectively receive, at least in part, the beam-reference portion. Second beam-locating feature is also configured to receive beam-reference portion once the beam-reference portion is inadvertently displaced away from first beam-locating feature and from vertically-extending construction column and toward second beam-locating feature.
