A form for forming a void or an architectural feature of a predetermined configuration in a moldable forming composition is disclosed. Embodiments of the invention provide an adjustable form body having first and second sides, said form body configurable between a first substantially planar position and a second non-planar position. In some embodiments, the form comprises a surface coating. A form body according to example embodiments of the invention has a plurality of grooves.

A liner for a form is provided. The form allows for the creation of a precast concrete wall to be formed. The liner allows a building material, for example, brick veneer, to be placed in the liner in a pattern. The pattern may be a soldier course that can formed over openings in the precast concrete wall. When liquid concrete is poured into the mold and then hardens, the concrete holds the building material in place in the pattern produced by the liner.

Features for formliners to form a decorative pattern in a curable material and methods of using the same are disclosed. An improved formliner is disclosed with substantially seamlessly connecting components that reduces the need for using adhesives for interconnecting a plurality of formliners in a pattern. Further, the formliner is configured to reduce and/or substantially eliminate visible seams in order to create a more natural appearance in a finished product of the curable material.

There is currently a demand for buildings that can be formed both quickly and economically. These buildings require the addition of heat insulation to walls or roofs because the materials from which they are otherwise formed have insufficient ability to protect against the cold. This can add undesirable expense and slow down production rates. A method is disclosed of forming a building that addresses this problem. The method comprises arranging a door frame, window frame or edge support frame at a mould and spraying a first spray material onto the outside of the mould so that the spray material sets generally in the shape of the mould and substantially embeds the frame. The first material and the frame is removed from the mould and a second different spray material is sprayed onto the first spray material to provide a skin therefor.

The present invention corresponds to a formwork mechanism for casting and molding concrete, comprising a coffer having a sheet and four plates around the sheet perimeter. Each plate has holes arranged on its front face. Also, the formwork mechanism includes a structural element, connected to one of the plates by fixing means. On the other hand, the structural element has lateral perforations that are aligned with the holes of one of the coffer plates. Fixing means pass through the holes and side holes. The structural element may be a beam, a three or four-beam T, and combinations thereof. On the other hand, using several coffers interconnected with structural elements, formworks are constructed for casting flat reticular slabs; and also for curved reticular slabs with greater slab thickness near the beams supporting the slabs in comparison to the span of the slabs.

The present invention provides for a method of creating a lustrous surface in opaque materials using ridge angles, and valleys of varying depths cut, imprinted or pressed into the opaque material. The combination of the light reflecting ridges, angles to reflect more or less light, and a shadow effect arising from a combination of the valley depths and the angle of the ridges allows one to use light and shadow to create a pattern or series of patterns in the opaque materials. These patterns are created using a process whereby a design is first created, then cut into a master blank using some type of manual or computer-aided method. Next, this pattern is inlaid, pressed, or imprinted into a blank panel composed of the opaque material. In some embodiments, this opaque material is allowed to set, thus creating a finished article of manufacture in the form of a panel.

The invention relates to a method and a device for controlling the delivery rate (P.sub.Q) of a concrete pump (1) for filling a formwork arrangement (2) with a pumpable filling compound (3) as a function of curing-relevant material and environmental parameters (RST), after which the installed filling compound (3) sets within the formwork arrangement (2), comprising the following steps: determining a permissible climbing speed (vsz) for filling the formwork arrangement (2) with the filling compound (3) on the basis of the material and ambient parameters (RST), measuring the static filling compound pressure (p.sub.F) acting on the formwork arrangement (2) during filling, calculating the permissible delivery rate (P.sub.Q) of the concrete pump (1) as a function of the determined permissible rate of ascent (vsz) and the measured static filling compound pressure (p.sub.F) at the formwork arrangement (2).
