A concrete form includes a first sidewall and a second sidewall positioned in parallel and spaced relation to each other, where the first sidewall has a first passage extending therethrough, with a first insert received in the first passage of the first sidewall. The form also includes a first cross tie having opposed first and second ends, where the first sidewall is removably secured to the first end of the first cross tie and the second sidewall is secured to the second end of the first cross tie. A first fastener extends through the first passage and engages the first insert and the first end of the first cross tie to removably secure the first sidewall to the first cross tie. The second sidewall may be removably or non-removably secured to the first cross tie.

A lifting anchor assembly that is configured to be embedded in a tilt-up concrete structure includes an anchor member that has a central portion configured to engage a lift apparatus and a pair of legs that extend downward from the central portion. A lower portion of each of the pair of legs includes a curved section configured to engage within a concrete structure during its forming process. A spacer may be selected to attach at an end portion of each the pair of legs, where the spacers each extend downward from the anchor member and rest on a floor surface of a concrete form to support the anchor member at a desired spacing from the floor and upright within the concrete structure that is cast in the concrete form.

A construction anchoring system includes one or more anchor apparatuses which are mountable relative to a form used to create a concrete support structure. The concrete is deposited in the form and cures whereby the one or more anchor apparatuses becomes embedded within the concrete support structure. The embedded anchor apparatus is readily accessible to be coupled with, or to support, construction supplies or equipment such as ductwork, electrical cables, plumbing, sprinklers, safety lines or fences, etc. within a construction site. A plurality of anchor apparatuses may be mounted relative to the concrete form to create a system for organizing the installation of construction materials and/or safety equipment.

A reusable form for creating conduit paths in concrete slabs is described. The form comprises a flexible tube that is positioned prior to pouring a concrete slab. The form includes a keep to keep material out of the hole formed by the form. The form also includes a key structure to permit easy removal of the form once the concrete is set. The system further includes a sighting device to permit rapid and precise alignment for placement of a form when forming conduits in a multi-level building. An accessory is also provided permitting filling in the opening created by the form once wiring, piping and other objects have been installed within the conduit.

The present invention relates to a profiled rail (2) for fastening to a formwork (5) for at least partially embedding in concrete. The profiled rail (2) is formed in a substantially C-shaped manner along a profiled rail longitudinal axis, wherein a plurality of holes (24) are formed in the rail back (21). Plugs (1) are inserted into some of the holes (24), wherein each plug (1) has a cap section (12) and an adjoining through section (10). The through section (10) fits through the respective hole wherein the cap section butts against the rail back (21). The plug (1) has a feed-through region (13) through which an elongate connecting element (4) can be pieced being guided by the feed-through region (13). The connecting element (4) is preferably a nail or a screw and connects the plug (1) to the formwork (5) holding the profiled rail on the formwork (5).

A pulling-out device for a prefabricated concrete support wall, belonging to the field of concrete support structures, wherein a vertical hollow tube is pre-buried in the prefabricated concrete support wall. The pulling-out device includes a pulling-out mechanism disposed in the hollow tube by penetration, the lower end of the pulling-out mechanism is fixedly arranged in the prefabricated concrete support wall and positioned at the lower end of the hollow tube, a first fixing device for tensing the pulling-out mechanism is arranged at the upper end of the pulling-out mechanism, and the first fixing device is not connected with the prefabricated concrete support wall.

An anchor for being embedded in concrete for attachment to a fastener to support a load comprises a plug having a main body portion extending upwardly from a base portion, the plug for being attached to a form board prior to pouring of concrete, the plug having an end portion disposed a distance from the form board; and an anchor body attached to the end portion. The plug is separable from the anchor body and removable from the concrete after the concrete is cured, leaving the anchor body embedded in the concrete, the plug providing a void in the concrete after removal to provide an access opening for a threaded portion of a fastener to attach to the anchor body.
