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 method for 3D printing a prefabricated modular building includes rotating an intermediate module (300) by 90 degrees to obtain a fabricated module (400), so that two originally vertical walls (A, C) become horizontal walls, and the other two walls (B, D) become supporting walls. This enables the building to be able to receive stresses as a whole, improving the stability of the building.

A robotic casting machine (RCM) provides for on-site, or near-site casting and automated production of cast components, such as concrete modular, volumetric building components. The RCM includes stationary and mobile support structures, which can be positioned in a loading configuration, a casting configuration and an ejection configuration in which the cast volumetric component may be ejected from the mold. Tipping machines located beneath the cast component facilitate ejection, rotation and loading of the ejected module onto a transport surface for transport of the module. The support structures are constructed of prefabricated frames that may include at least one standardized section, which may be utilized on every project, and may also include a customized section, which may be provided to achieve desired dimensions of the cast module on a particular project. A casting process is provided in which a volumetric module is cast in a rotated orientation, in which the floor is cast with an initial vertical orientation, the transverse walls extend in a horizontal orientation, which is cast in vertical wall forms, and a longitudinal wall extends horizontally along the top of the mold. Modular, volumetric components created using the RCM and casting process are also described.

A system for retaining a flowable and curable building material to form a portion of a foundation includes side walls disposed in a predetermined configuration having a first side wall and a second side wall, and at least one component having an interior cavity disposed in one of the side walls. A bracket assembly includes an outwardly bounding reinforcement post for each of the side walls, a separator bar having a plurality of apertures sized to receive and retain each of the reinforcement posts at locations corresponding to nominal widths of the at least one component. A barrier is disposed between the outwardly bounding posts. The barrier and the component in the side wall is retained in the foundation after the building material cures. The barrier prevents backfill from filling a volume between the outwardly bounding posts.

A formwork apparatus defining a formwork space for forming a slab is disclosed. The apparatus comprises at least one lower formwork member and at least one upper formwork member and a plurality of formwork brackets. Each formwork bracket has a connection arrangement for operatively connecting the bracket to the lower and upper formwork members. The formwork brackets are configured to space the upper and lower formwork members a certain distance apart from each other along their length such that the formwork members extend parallel to each other. An apparatus for positioning an anchor for a construction member such as a reinforcing rod in a slab when it is cast is also disclosed.

A bulkhead assembly for use with a concrete form and a first reinforcement bar is disclosed. The concrete form may have first and second spaced form sides; and the first reinforcement bar may be disposed between and may extend longitudinally of the spaced form sides. The bulkhead assembly may have a first pair of channel assemblies, each including a channel member and an elastomeric member. The elastomeric member may be positioned longitudinally in the channel member, with a portion of the elastomeric member extending outward transversely from the channel member. The portion may include an outer end that extends longitudinally of the channel member. The channel assemblies may be positioned on opposite sides of the reinforcement bar, with the elastomeric member outer ends facing one another and contacting the reinforcement bar, thereby inhibiting uncured concrete from passing between the channel assemblies when uncured concrete is poured into the concrete form.

A formliner, sheet, system, and methods of use and manufacture are provided in order to provide a product that can minimize and/or eliminate visible seaming between interconnected formliners during fabrication of a pattern on a curable material. In some embodiments, the formliner can comprise raised sections that define interrelated inner and outer dimensions. Thus, a plurality of formliners can be interconnected by overlaying raised sections thereof. Further, the formliner can comprise one or more detents and one or more protrusions to enable engagement between interconnected formliners without requiring adhesives. In this manner, formliners can be interconnected in a nested manner such that visible seaming between the interconnected formliners is reduced and/or eliminated.
