摘要： A retractable, removable and reusable tie assembly for concrete forms includes a single tie rod having a pipe slidably mounted on one end thereof and an internal spreader system interposed between its ends for spacing the forms a predetermined distance apart during concrete pour. The internal spreader system includes a loose cone adapted to be threadedly engaged with one end of the pipe and a rubber tube adapted to sealingly engage with this cone as well as a second cone secured to the other end of the tube. This connection includes a ferrule and insert engageable with a steel washer embeded in the secured cone. The insert is interiorly threaded to facilitate removal of the cone and attached rubber tube after the forms have been stripped. Interengaging surfaces of threaded insert and the rod assure the proper location of the internal spreader system after the first and closing form have been erected. Wedges at each end of the tie assembly completes the erection of the forms. After the concrete has been formed and satisfactorily hardened the forms are then stripped. Towards this end, the rod and associated pipe are removed by initially uncoupling one or both of the wedges and then unscrewing the pipe from its associated cone. Thereafter the loose cone may be removed with a suitable tool or bolt with a thread mating with the internal thread of this cone. The other cone and secured tube may then be removed by means of a second tool or bolt having a threaded portion mating with that of the thread of the insert. The tie assembly may then be reused where desired.

摘要： 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.

摘要： A retractable, removable and reusable tie assembly for concrete forms which includes a single tie rod, and an internal spreader and spacing system which includes a sleeve means, the spreader system having built-in provisions for internal spreading and spacing of forms in such a manner as to permit the tie rod to be partially withdrawn on one side of the form facilitating the installation of the closing form, on the opposite side, and then to be inserted to engage and lock with the internal spreader system, thus keeping the two adjacent sides of the forms in a definite predetermined position apart during the concrete pour, then to be removed undamaged from the hardened concrete prior to dismantling of the forms, leaving the internal spreader in the concrete to be removed after stripping of the forms without damaging the internal spreader.
