The invention comprises a concrete form. The form comprises a first concrete forming panel having a first primary surface adapted for forming and contacting plastic concrete and a second primary surface opposite the first primary surface; a layer of insulating material contacting and substantially covering the second primary surface of the first concrete forming panel; and an insulating blanket adjacent the first concrete forming panel. A method of using the concrete form is also disclosed.

A tie rod suitable for use with a concrete forming system, comprising one or more button rod elements, wherein the button rod element has an elongated main body having a first end region having a head portion, an opposed second end region having an anchor portion, and an intermediate region, wherein the second end region or the intermediate region has one or more relatively flat cut-outs formed therein. The tie rod also includes a continuous fiber wound about the anchor point and the cut-outs to form the tie rod.

The invention comprises a product. The product comprises a first removable concrete form having a concrete forming face and a first insulating panel insert having a first primary surface and an opposite second primary surface, wherein the second primary surface of the first insulating panel insert contacts the concrete forming face of the first removable concrete form. The product also comprises an elongate anchor member having an enlarged portion and an elongate portion, the elongate portion having a first end and an opposite second end, wherein the enlarged portion is disposed adjacent the first end and contacts the second primary surface of the first insulating panel insert and wherein the elongate portion extends through the first insulating panel insert and extends outwardly from the first primary surface of the first insulating panel insert. A method of using a removable insulated concrete form system is also disclosed.

Various implementations described herein are directed to a formwork system. In one implementation, the formwork system includes aluminum extrusions and aluminum castings. The aluminum castings and the aluminum extrusions can be assembled by being pressed and riveted together.

A connector assembly (400) for connecting a pair of formwork panels (200) with each other is disclosed. The connector assembly (400) includes a base component (402) having an arm, a first opening (602) formed on the arm, and a locking portion (406) formed at an end of the arm and adapted to be removably inserted in a second opening formed by alignment of respective slots (204) of the pair of formwork panels (200). The connector assembly (400) further includes a handle component (404) adapted to be partially disposed in the base component (402) through the first opening (602) formed on the arm. The handle component (404) is adapted to be operated to rotate the arm such that the locking portion (406) is rotated within the first opening (602) to partially lock the base component (402) in the first opening (602) for connecting the pair of formwork panels (200).

A concrete formwork construction having a formwork element (1) whose frame (3) is produced from flat steel, whereas the struts (4) of the formwork element (1) are formed of sectional steel.

A panel for formwork for vertical castings, comprising: a frame for supporting a plane, the frame comprising two end posts and two end crossmembers, the two end crossmembers extending between two end posts, the plane being associated with a first portion of the frame, to be directed toward the inside of the formwork, the frame forming a quadrangular external perimetric border for the panel, the plane having an external perimetric border that substantially coincides with the external perimetric border of the frame; the panel has, at the corners of the perimetric border, at least some of the edges that are only partially sharp.

The present invention provides a transmitter for predicting stress on a formwork element (10) during and/or after pouring a building material (M), in particular concrete, into a space enclosed by a formwork (2) including the formwork element (10), the formwork element (10) comprising a form face (12) and a support structure (14) which is attached to the form face (12) and supporting the form face (12), wherein the form face (12) is separated from or integrated into the support structure (14), the system (1) comprising data acquisition means (16a, 16b, 16c, 16d, 16e), at least one sensor unit (18a, 18b, 18c, 18d, 18e), a control unit (20a, 20b, 20c, 20d, 20e) and a transmission unit (22a, 22b, 22c, 22d, 22e).

The present invention relates to a formwork system (1) comprising a form lining (2) and at least one shaped element (10) which is attached to the rear side (4) of the form lining (2). The form lining (2) and the shaped element (10) have been produced by a 3D printing method. This is preferably carried out in a common 3D printing process, but the form lining (2) and the shaped element (10) can also be produced in separate 3D printing processes, with the shaped element (10) then being attached to the rear side (4) of the form lining (2). This is effected using at least one first fastening element (50). If, by contrast, the form lining (2) and the shaped element (10) have been produced in a common 3D printing process, the additional use of a first fastening element (50) for fastening the shaped element (10) to the form lining (2) is not required. According to the invention, the shaped element (10) and optionally the first fastening element (50) are attached to the rear side (4) of the form lining (2) in such a way that they do not touch or pierce the front side (3) of the form lining (2). The present invention also relates to the use of such a formwork system (1), for example in the production of structural elements made of concrete.

A transmitter for predicting stress on a formwork element during and/or after pouring a building material, in particular concrete, into a space enclosed by a formwork including the formwork element, the formwork element comprising a form face and a support structure which is attached to the form face and supporting the form face, wherein the form face is separated from or integrated into the support structure, the system comprising data acquisition means, at least one sensor unit, a control unit and a transmission unit.
