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.

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.

Stay-in-place forms and methods and equipment for installing thereof. A concrete form includes a vertical component and a horizontal component, the vertical component located substantially perpendicular to the horizontal component. Also, the form includes an interior surface, at least a portion of the interior surface providing a form for supporting uncured concrete; wherein the uncured concrete forms a concrete structural portion upon curing of the uncured concrete; and wherein the interior surface remains attached to the concrete structural portion after curing. The form may include inserts and compatible form attachments. Also, forms including recesses may be utilized to reduce the weight thereof. Lifting equipment and accessories may be utilized to lift the form from a form holder and set same in place. Forms contain the work area as soon as it is installed to minimize fall hazards and the time, costs, and downtime associated with installation of safety measures.

The invention relates to a building structure comprising pillar units, beam units including main beam units and floor slab units, the floor slab unit comprises a floor slab template layer and a floor slab framework unit; the beam unit comprises a beam template layer of concrete and the beam framework unit; the pillar unit comprises a pillar framework unit, the pillar framework unit comprises a pillar keel unit and support legs; the pillar framework unit comprises a pillar keel unit and support legs; the longitudinal section steel major keels supported on the main beam major keels and the steel bars protruding out of the floor slab template layer in the side direction are placed above the main beam units; the cells are formed between the adjacent beam units; more than one floor slab units are installed in each cell. The advantages of the invention are no support frames, no removing the template.

A drainage device for use under the floor of a building to facilitate drainage of water along a foundation of the building under the floor. A bridge drainage device permits more rapid installation of the drainage devices. The bridge device can be used to bridge between two drainage devices so that it is not necessary to cut the drainage devices precisely to fit on a footing of any selected length.

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, and a support foot for supporting the system relative to a ground surface, wherein the first part has a pair of vertically opposed longitudinal rails, and the support foot has an engagement formation which has an unlocked orientation for inserting the formation between the opposed rails to abut against the first part and a rotated, locked orientation wherein the formation is locked by the rails against lateral withdrawal from the first part.

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, 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.

An edge protection system for use with concrete flooring, including an initial edge unit having a first part and a second part, the first part for coupling to an edge portion of a first concrete flooring panel and the second part for coupling to an opposed edge portion of a second, neighbouring, concrete flooring panel, the system also including an angled edge unit having a first part and a second part, the first part for coupling to another edge portion of the second concrete flooring panel and the second part for coupling to an opposed edge portion of a third, neighbouring, concrete flooring panel, and a modular intersection part at an intersection of the first to third panels, wherein the modular intersection part is adapted to be coupled to the initial edge unit with the initial edge unit extending radially from the modular intersection part in a first direction, and wherein the modular intersection part is adapted to be coupled to the angled edge unit with the angled edge unit extending radially from the modular intersection part in a second direction at an angle to the first direction.
