An internally braced permanent formwork for concrete foundation construction is provided in order to achieve a quick and simple assembly. The formwork comprises a base member laid on the ground having a perimeter recess on an upper surface for receiving components of the formwork. One or more permanent outer boards forming an outer periphery of the foundation are provided and coupled to a plurality of spaced internal bracing components to prevent collapse under the pressure of wet concrete.

The invention relates to a ceiling formwork and a method for producing a ceiling element, comprising the following steps: arranging two ceiling supports on a floor, connecting a first end region of a ceiling formwork frame to the two ceiling supports such that the ceiling formwork frame is arranged in an intermediate position inclined downward from the first end region in the direction of a second end region, connecting a lost ceiling plate to the ceiling formwork frame arranged in the intermediate position, pivoting the second end region of the ceiling formwork frame up, together with the lost ceiling plate, supporting the second end region of the ceiling formwork frame that has been pivoted up by at least one additional ceiling support and casting the ceiling element, together with the lost ceiling plate, on the ceiling formwork frame.

An edge protection system for use with concrete flooring, including a first part for coupling to an edge portion of a first concrete flooring panel and a second part for coupling to an opposed edge portion of a second, neighbouring, concrete flooring panel, wherein the protection system is provided in modular lengths, and wherein adjacent modular lengths are coupled by one or more bridging pins.

An edge protection system for use with concrete flooring, including a first part for coupling to an edge portion of a first concrete flooring panel and a second part for coupling to an opposed edge portion of a second, neighbouring, concrete flooring panel, wherein the system includes a retaining clip for retaining the second part to the first part, the retaining clip being frangible to allow separation of the first and second parts after setting of the first and second concrete flooring panels.

An edge protection system for use with concrete flooring, including a first part for coupling to an edge portion of a first concrete flooring panel and a second part for coupling to an opposed edge portion of a second, neighbouring, concrete flooring panel, wherein the system includes a retaining clip for retaining the second part to the first part, and the first part is slideable relative to the second part to engage the retaining clip against removal from the first and second parts.

An edge protection system for use with concrete flooring, including a first part for coupling to an edge portion of a first concrete flooring panel and a second part for coupling to an opposed edge portion of a second, neighbouring, concrete flooring panel, a dowel plate and a dowel sheath, wherein the dowel plate is for supporting the second concrete flooring panel relative to the first concrete flooring panel, the dowel sheath is fitted to extend laterally from the first part, with an internal cavity of the dowel sheath aligning with apertures formed in the first and second parts such that the dowel plate is able to be inserted into the dowel sheath cavity through said apertures to a supporting position in which the dowel plate remains in the apertures and extends laterally from the second part.

A cement form includes a single piece, unitary body member having a solid, continuous construction and a wedge-shaped cross-section. The body member includes a first surface arranged vertically and configured to support a volume of cement, a second surface arranged horizontally and configured to contact a ground support surface, a foam material, an elongate construction with a greater length dimension in a horizontal direction than a height dimension in a vertical direction, and a notch formed at an intersection of the first and second surfaces, the notch being receptive of a portion of a foam sheet or other foam extension member.

The present invention relates to a prefabricated deck unit for a building system, the deck unit including: a reinforcing framework encased in a composite material, the reinforcing framework comprising: a first metal mesh unit, a plurality of interspaced spheroidal void formers attached to or in intimate contact with the first mesh unit, and a second mesh unit resting upon, or attached to, the spheroidal void formers, wherein the framework defines at least one terminal channel on at least one end of the deck unit, the terminal channel being shaped and dimensioned to snugly receive an elongate connecting rod for connecting the deck unit to a further structural element of the building system.

System for fixing to the ground walls of a building includes a plurality of supporting elements interposed between a concrete foundation of the building and the walls, connecting elements for connecting at least two supporting elements that are aligned on one another, adjusting elements for adjusting a distance of the supporting elements from the foundation and for correcting a possible tilt of the supporting elements with respect to a horizontal reference plane, anchoring elements for anchoring the supporting elements to the foundation, the supporting elements being made of plastics.
