| 摘要 |
The invention relates to an extendable prop which applies axial pressure between two parallel planes by means of an integrated elastic element, providing active propping. The extendable nature of the prop allows said prop to be easily installed and removed without labor, as well as allowing the pressure exerted by the elastic element to be regulated. The prop can also be used as a structure for dry-mounted cladding, by means of removable securing cladding panels to tubular elements, especially to securing devices in the form of a spring clip suitable for being anchored to a tubular element and provided with coupling configurations suitable for the anchoring of one or more cladding panels. |
