US Patent:

40449874, Aug 30, 1977

Filed:

Nov 3, 1976

Appl. No.:

5/738549

Inventors:

Dusan Tausanovitch - Northport NY
Peter R. Lovisa - Pelham NY
Tullio E. Lovisa - Huntington NY

International Classification:

E04G 1700
E04G 1106

US Classification:

249219W

Abstract:

An externally controlled spreader system is designed for the adjustment of forms in both lateral directions and includes a nut having a continuous circular notch on its exterior surface which cooperates with a slotted hole in a slidable plate externally mounted on a washer which is connected to the forms. The nut is adapted to be coupled with the threaded end of a tie rod to apply an axial force, and in this manner the forms are moved laterally in the desired direction while being maintained at a selected predetermined distance apart.

International Classification:

E04G 1708

US Classification:

249 42

Abstract:

A feed-through, self-sealing tie assembly for mounting as a unit on concrete forms and capable of being removed therefrom without disassembling the forms or the tie assembly is disclosed. The tie assembly includes an elongated tie rod on which is mounted an elongatable, elastomeric sleeve. The sleeve and the tie rod have interengageable surfaces for releasably coupling the sleeve to the tie rod. Guide means positioned over one end of the sleeve facilitates insertion of the tie assembly through corresponding spaced openings in the forms so that both ends of the sleeve are projected exteriorly of the forms. The openings are sealed by the elastomeric sleeve due to the lateral deformation of the sleeve when in the form openings and by the compressive forces exerted by the concrete on the tie assembly. Thus, the elastomeric sleeve provides a self-sealing and removable closure. Wedges or nuts cooperate in coupling the tie rod to the forms; and external spreader brackets are provided to maintain the forms apart the prescribed distance.

US Classification:

249 40

Abstract:

An externally controlled spreader system is designed for the adjustment of forms in both lateral directions, and is capable of being remotely activated as the forming operations require. This system is advantageously built into existing tie holding devices and includes a nut having a continuous circular notch on its exterior surface with an elongated member having a slotted hole adapted to be slideably connected to a conventional plate-washer. The slotted hole on the slideable member is modified in shape to engage or disengage the continuous notch on the nut, respectively, and consequently conform it to the position of the slideable member, without restricting its rotation. During threading, the nut exerts a force on the plate-washer assembly, which is adequately connected to the forms, and thus moves the forms laterally in the desired direction, while maintaining them constantly at any predetermined distance apart through the rigid tie rod.
