摘要： There is disclosed a steel tube prop for ceiling formwork with two telescopically interengaging tubes of which the outer one has a screw thread on its interengaging end and in the region of the thread contains an elongated hole passing through it radially and extending in the direction of the longitudinal axis of the support, through which hole can be inserted a pin which also passes through a hole in the inner tube, the pin being capable of being supported on a threaded sleeve which is screwed onto the thread of the outer tube. The pin has two engaging surfaces for the inner tube at different radial distances from its axis or in different planes and spaced apart by an amount determined by the diameter of the inner tube so that the inner tube can be lowered from a normal operative position into another position in a simple manner, for example, by a hammer blow on the pin.
