In a one aspect there is disclosed a formwork wall panel (10) having an operative inner surface (12) to face towards an inner space to be filed with building material and an opposing operative outer surface (14) having a surface finishing component (16) secured thereto. The operative inner surface (12) of the formwork wall panel (10) includes a brace coupling formation (18) operatively adapted to engage a wall panel coupling formation (20) of a brace (22) operatively extending between the formwork wall panel (10) and an opposing second formwork wall panel.

A formwork stud system includes a plurality of studs, a top channel, a bottom channel and a plurality of horizontal and vertical rebars. At least one of the plurality of studs is a formwork stud. The formwork stud includes a web and a pair of flanges. The web has opposed side portions extending from the top of the formwork stud to the bottom of the formwork stud and a plurality of lateral spaced apart connectors extending between the opposed side portions. The opposed side portions and the lateral spaced apart connectors define a plurality of spaced apart holes. The holes are configured to allow concrete to flow therethrough. The pair of flanges extend generally orthogonally from the opposed side portions of the web.

The invention has for object a method for manufacturing concrete construction blocks (6) for a wind-generator tower made up of at least two consecutive blocks secured to one another by a contact surface of each of the two blocks, the manufacturing method comprising the following steps: pouring concrete into a first cage of reinforcements (10-1) so as to obtain the first concrete construction block comprising a first contact surface (9), and pouring concrete into a second cage of reinforcements (10-2) so as to obtain the second concrete construction block, the second cage of reinforcements being provided in a form (21) arranged such that the first contact surface (9) of the first block (6-1) makes up a wall for delimiting (26) the pouring of the concrete such as to form a contact surface (9) of the second block (6-2).

Disclosed herein is a method for erecting a shuttering framework. The method comprises the steps of a) mounting one end of a first support to the ground or other stationary object and mounting one end of a first brace to the ground or other stationary object, b) attaching the opposite end of the first brace to the opposite end of the first support or to a position between the two ends of the first support, c) repeating a) and b) for a second support and a second brace, and d) mounting a plurality of ties between the first and second supports. Also disclosed herein is a method of casting concrete.

The invention relates to a sheet (10) for protecting a form-work surface, intended to surround a construction material. According to the invention, the sheet (10) comprises at least: a front layer, including at least one polymer material and provided to be in contact with the construction material so as to reduce wear and the formation of grooves on the framework surface and to limit adhesion of the construction material during removal of the formwork; and a rear adhesive layer, provided to be positioned against the formwork surface and rigidly connect the sheet (10) to the formwork surface before the construction material is introduced. The invention also relates to a formwork installation (1) equipped with at least one such sheet (10). The invention further relates to a method of producing and a method of using a sheet (10) of this type.

A system, comprising: at least one planar member having a two- or three-dimensional surface pattern formed thereon or therein; and a plurality of resilient spacers removably positionable on or in the surface pattern to form a surface relief pattern of spaced-apart recesses on the at least one planar member.

Buildings are constructed using the tilt-up technique from concrete elements that have contours that are at least partially curved. The concrete elements are made by casting in molds. The molds are assembled from mold pieces selected in a kit that contains a limited set of shapes. Molds assembled differently can produce concrete elements with a large variety of contour shapes.

The insulating concrete form system includes longitudinal and corner block assemblies each having a pair of side panels configured with tie receivers interacting with panel spacing ties to hold the side panels in an opposing manner and leading edges with an alternating arrangement of projections and recesses for interlocking with neighboring block assemblies. Each panel spacing tie includes a mid-support section interposing in between and connecting to a pair of end sections by a living hinge with each end section being configured with a flange member for placement within an opposing spatial wedge of the tie receiver, whereby the living hinge possesses the capability of allowing the side panels to move inwardly toward one another in a racked position to yield compactness of the longitudinal block assembly for economical transport. The corner block assembly also includes corner panel spacing ties to supplementally reinforce its structure to withstand hydrostatic blowout caused by poured concrete.
