A removable form tie system and methods of construction using same are disclosed. The removable form tie system may comprise first and second brackets for respectively mounting to a first and second forms spaced apart from one another. A wire runs from the first bracket to the second bracket. Each bracket preferably comprises a fastening wall and a channel adapted to receive one end of the wire. Each bracket may further comprise a holder for receiving the wire at a substantially orthogonal angle after being received by the channel. The holder may comprise a portion of a stiffening wall extending substantially orthogonally away from the fastening wall, as well as a detent extending substantially orthogonally away from the first stiffening wall. In the alternative, the holder may be an extension from the fastening wall, wherein the holder extends substantially orthogonally away from the first fastening wall and then bends back to be generally parallel to the first fastening wall. Where the forms are plywood, a bracket may include a stiffening wall extending generally orthogonal away from the fastening wall, wherein the stiffening wall includes a sleeve adapted to receive a pin. Methods of using the form tie system include using the brackets with sleeve and pin arrangement to secure one or more braces, such as walers or strong backs, to maintain rigidity of the forms. The disclosed inventions advantageously permit wet concrete to be poured between the forms and troweled with ease. The wire may be easily removed from the concrete, even days after the concrete has cured, for an aesthetically pleasing result without concern of wire oxidization issues.

A seal for a lead-through for a tie rod through a panel formwork element. The seal includes a sleeve, a sealing element and a sliding tube, which are disposed on the tie rod and, together with the tie rod, are placed through the panel formwork element from a rear side, so that the sealing element exits the panel formwork element on a front side and, after brief pulling back of the tie rod, provides sealing between the sleeve and the panel formwork element, for one-sided anchoring.

A sleeve assembly is provided comprising an inner tubular member and at least one outer sleeve that receives at least a portion of the inner tubular member. The outer sleeve may longitudinally telescope with the inner tubular member to move between a non-expanded position and at least one expanded position. In some embodiments, the inner tubular member comprises a first locking component and the at least one outer sleeve comprises a second locking component that interlocks with the first locking component to secure the outer sleeve in the non-expanded position and/or at least one expanded position. Related methods for making a sleeve assembly are also provided.

An apparatus for connecting a pair of wall concrete form sections disposed at a relative distance from each other defining a space therebetween to receive concrete to be poured, the apparatus preventing the sections from separating, the apparatus comprising an elongated locking pin, a form connector to be rotatably, and releasably affixed to a form, and a pin retainer affixed to the arm defining a channel therein sized to be engaged within the engagement slot whereby the pin is placed through corresponding holes in adjacent forms and the pin engages a first form, extends through the relative distance between the forms, exits through an aligned hole in the second form, and the channel of the pin retainer attached to the second form engages the engagement slot on the pin thus providing a fixed distance between the forms and preventing the form separation when concrete is poured.

The invention relates to an anchoring system for a wall formwork as well as to a method for suspending the anchoring system on the rear side of a wall formwork while dismantling a wall formwork. In order to accelerate a dismantling process, an anchoring system with an anchoring rod (4) and at least one disengageable locking device is provided. The part of the anchoring system that is pulled out of wall formworks after a concrete wall has been produced comprises a suspension means for suspending on a wall formwork the part of the anchoring system that has been pulled out.
