摘要： A construction fence post including a hollow tubular post having a C-shaped mounting bracket at the lower end thereof, a shank extending through the hollow tubular post and projecting outwardly thereof towards an oppositely disposed arm of the C-shaped clamp and drive means at the upper end of the post for driving the shank towards and away from said arm of the C-shaped clamp to releasably clamp a structure disposed therebetween. The shank is resiliently longitudinally compressible whereby the clamping force is maintained between the shank and the arm when the proportions of the structure which is disposed therebetween vary due to temperature variations or the like.
