Tableframe Heavy Duty Shoring - Detailed Information

01What Is Tableframe?

Tableframe is an EN 12813-certified table shoring system in which 150 cm wide welded steel frames are connected with braces and brought to slab soffit level with base and top jacks. It is used to carry heavy loads down to the ground under thick and high slabs.

The four legs of each tower are vertical tubes of Ø60 mm diameter. That is a larger section than the Ø48 mm standard scaffold tube, and it is what sets table shoring apart from lighter shoring systems. The frames are welded in one piece in our factory, so on site the crew only has to place the frames, fit the braces onto the pins and adjust the jacks.

On top of the frames come the top jacks with four-way heads, then the primary beams, secondary beams and plywood. This upper part can be built in place, or prepared together with the tower as a single table. That is where the system gets its name.

02Are Table Shoring and Table Formwork the Same Thing?

On site the two terms are often used interchangeably, but they describe different things:

• Table shoring: The load-bearing part, meaning the frames, braces and jacks. On its own it is a shoring scaffold; after the pour it can be dismantled and erected again elsewhere.
• Table form: The table shoring with beams and plywood fixed on top, turned into a single unit. The unit is rolled out, lifted and reused at the next pour without being taken apart.

In other words, every table form has table shoring underneath, but not every table shoring is used as a table form. On jobs with little repetition and changing levels and sections (bridge decks, power plant buildings, one-off high atriums) Tableframe usually works as shoring erected in place. In buildings where the same slab repeats floor after floor, using it as a table form saves time.
