Jacks are temporary supports that perform 2 important tasks at once:
- support horizontal panels of the formwork system of floors during concrete solidification;
- allow fixing horizontal elements of the formwork system.
Telescopic jacks for shuttering floors consist of the following main parts:
- The external and internal supports, which are 2 pipes, one is inserted into the other. The racks have a square support, which allows them to be anchored, to ensure high stability. Jacks can change their height by extending the inner tube.
- Elements for fixing the inner and outer pipes. These are nuts and earrings. The earring is a removable retainer that serves as a stopper for the upper pipe. The nut is responsible for the support of the earring. The performance characteristics always indicate the maximum permissible height of the telescopic jack rack, which directly affects its bearing capacity.
Also, additional devices are made to the telescopic racks, which are necessary for the installation of the formwork of the floors, namely:
- univilki, they are used to fix beams made of wood and formwork tables;
- tripods, which allow you to ensure maximum stability of the racks, to center them vertically.
The technology of mounting telescopic racks is quite simple. The racks are assembled at the construction site. To do this, a nut is screwed onto the outer pipe, which has a thread, and then an earring is thrown. A univil is mounted on the inner tube, and the outer one is inserted into the installed tripod. After connecting the pipes, setting the required height, fixing occurs with the help of earrings. Then beams are installed on the univilks, plywood is laid.
