Locking device for access tubes in cage reinforcement structures
An arrangement comprising, in combination, a reinforcement cage (2, Fig. 1) for incorporation into a pile or other structure during the formation thereof, and one or more longitudinal access tubes 6 mounted within the cage for the purpose of subsequent testing or monitoring thereof. the or each access tube is provided with a locking device (60) for temporarily locking the tube in a substantially fixed longitudinal position relative to the cage. The locking device comprises locking means 70, 80 constructed and arranged for selective actuation to either (i) lock the access tube in the said substantially fixed longitudinal position relative to the cage (ii) permit sliding longitudinal movement of the access tube. In embodiments the locking device comprises a spring-loaded, R-clip-securable, rotatable latch member 80 with a nose portion 84 for securement behind or around a stirrup 20 used to support the access tube within the cage and an attachment member attached to the access tube and between which and the nose portion of the latch member 80 the stirrup is trapped when the locking device is in its actuated, locked condition. Also claimed are the lockind device, an access tube with the locking device and a method of securing an access tube to a reinforcement cage.
