Definitions

  • the present invention relates to tubular telescopic props, used in particular on public works, civil engineering, building sites, etc.
  • the slide having substantially the same length as the bole (economical design allowing to obtain the maximum length of the forestay for the minimum of material), the plate of the slide can come into contact with the nut when the forestay is closed. If you handle the forestay without special precautions after removing the spindle, you can get your hand crushed between the plate of the slide and the nut, if the forestay suddenly closes under the effect of the simple weight of the slide (more than 10 Kg for some props).
  • the conventional forestay shown in Figure 3 has two reinforcements 13 and 14 to prevent the barrel and the slide being damaged by ground blows, when placing or removing the forestay without playing on the nut.
  • the reinforcement 13 has no disadvantages for security.
  • we can easily see that the reinforcement 14 whose length is of the order of 10 cm to 15 cm risk of pinching your hand if it can come too close to the nut 6.
  • Figure 7 is an alternative embodiment of the invention.
  • the tubular stop 15 can be replaced by a set of washers or metal discs 17 fixed inside the tube 2, for example by welding.
  • all of the discs or washers 17 provide security and strengthen the base of the barrel.
  • the washers are preferable to the discs, because they allow to keep an opening at the base of the barrel. Obviously, we can adopt the same arrangement to strengthen the head of the slide.
  • the telescopic struts according to the invention can be used advantageously for all uses of conventional struts because they provide more security and have a longer service life. They can thus be used as formwork supports for floors cast in place, as temporary supports for floors cast on slabs, as beam formwork supports, as temporary shoring of prefabricated beams, as drying props supporting beams or floors after formwork removal, during the concrete hardening period and generally for all shoring operations.
