    摘要: A system is disclosed of making up formwork ties on site from standard components which are supplied. The components comprise length of stock rod, continuously threaded and provided with two diametrically opposed longitudinal slots (5) by means of which the rod may be lockingly engaged for manual rotation. A length of rod (4) threadedly engaged with a tapered member (1) forms a she bolt, the two parts being prevented from relative rotation by keys (6) inserted in the bores formed by the registering slots (5) and internal grooves (3) formed in the tapered member (1). A locknut (8) provided with a cavity (9) maintains the keys (6) in their bores. A connecting member (15) enables ties of any length to be made up from a number of shorter lengths of stock rod. The rod itself may serve other on site purposes such as reinforcement for concrete.

    摘要: An isolator (10) includes a load bearing part (15) arranged for deflection against the action of a series of compression springs (21) and tension springs (17) whose axes are pivotal with respect to the axis of deflection. The arrangement is such that the isolator can operate in a range in which an incremental increase in deflection causing compression of springs (21) is such as to result in an incremental decrease in the restoring force of springs (21) resolved along the deflection axis. The tension springs (17) produce an increasing restoring force throughout this range, and the net result is a load/deflection performance in which a region of zero or near zero stiffness of the entire system, along the deflection axis, is provided, bounded by regions of positive stiffness.
