A shoring assembly for utility vaults. A crossbeam member is carried by a column member and a bracket is connected between the crossbeam member and the column member. The bracket supports the crossbeam member on the column member and comprises a jack member that is extendable upward to engage and move the crossbeam member upward relative to the column member into a support position against a vault roof to be shored.

A formwork for performing horizontal castings for the provision of floors, of the type comprising a series of props, and supporting heads to be arranged on the props for the resting of panels designed to form a surface for a concrete casting, each panel comprising at least two longitudinal profiles, for resting on the supporting heads; each one of the longitudinal profiles comprises a central body, a first longitudinal part, for the fixing of the transverse elements, and an opposite second longitudinal part, each one of the supporting heads comprises a plate-like base from which there extends at least one lateral shoulder for the resting of the central body of a longitudinal profile in an intermediate configuration for assembly or disassembly, and a central protrusion, which protrudes from the same side as the lateral shoulders.

The present invention relates to a formwork arrangement for forming a suspended concrete floor slab comprising a change in level in an underside thereof, a support bracket for use with such a formwork arrangement, and a method for employing the support bracket and formwork arrangement.

A main beam for a formwork grid construction component system is disclosed. Typical main beams work with secondary joists (sometimes referred to as secondary beams to support a decking surface for pouring of concrete or cement. By strengthening the main beam using an altered profile while maintaining interoperable external dimensions, the span distance of each joist may be increased. By forming the main beam with the disclosed profile, joists can be made longer (e.g., have an eight foot connected span to increase grid size) and maintain appropriate strength (or increased weight tolerance). Formwork grid systems are used in construction of buildings and other structures. Interoperability with existing components is maintained by the disclosed main beam adhering to the same external functional form factor. The external form factor being the same allows main beams constructed in accordance with this disclosure to properly function with existing formwork grid construction components.

A drophead nut for use with formwork building components is disclosed. The disclosed drophead nut maintains standard outward dimensions to allow interoperability with existing systems. The hitting surface of the drophead nut is typically used to align a gap in the nut with a retention pin and thus allow the nut to drop. This in turn allows a mid-plate to fall releasing pressure on a beam (joist and/or main) to allow that beam to be removed. The impact surface of the disclosed drophead nut has been enlarged, reinforced, and possibly repositioned to increase leverage. The resulting drophead nut may allow for reduction in number of impacts on an impact surface to provide alignment of the gap and retention pin, and thus activate compression of the drophead nut.

The invention comprises a product. The product comprises a first removable concrete form having a concrete forming face and a first insulating panel insert having a first primary surface and an opposite second primary surface, wherein the second primary surface of the first insulating panel insert contacts the concrete forming face of the first removable concrete form. The product also comprises an elongate anchor member having an enlarged portion and an elongate portion, the elongate portion having a first end and an opposite second end, wherein the enlarged portion is disposed adjacent the first end and contacts the second primary surface of the first insulating panel insert and wherein the elongate portion extends through the first insulating panel insert and extends outwardly from the first primary surface of the first insulating panel insert. A method of using a removable insulated concrete form system is also disclosed.

A bracket configured to support a guardrail assembly of a construction platform.

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.
