Tecbor® Boards - Steelwork Protection

Steel structures are used for building purposes worldwide. One of the main advantages is that they have great resistance per weight unit, which provides them with huge versatility and the possibility of creating complex yet light
structures.

However, the thermal conductivity of steel represents a disadvantage. Therefore, in the event of a fire, the gradual increase in temperature plus steel high heat transmission result in a substantial reduction of the structure’s bearing capacity and mechanical resistance.
The resistance and elastic limit are modified above 250°C, and above roughly 500°C the drop in resistance is signifi cant enough not to support its design capacity.

mercor tecresa® has conducted numerous tests with Tecbor® according to UNE EN 13381-4, standard, in which is determined the contribution of fire protection of the board when we protect steel structural elements, either on
beams, columns or bearing elements.

Tecbor® has been tested to cover a great variety of steel profiles characterised by their section factors. Likewise, it has been tested for several standard specifi ed design temperatures.

SOLUTION


1. Tecbor® Boards.
2. Tecbor® joint paste.
3. Support stiffener for 20mm Tecbor® board.
4. Fixing bracket (dimensions according to board)
5. Steel profile.

Description of Assembly

Cut support stiffeners with Tecbor® boards of 20 mm, of 100 mm in width and adapted to the measurements of the metal profile to be protected. Insert them using a wedge as indicated in the detailed plans at intervals of no more than 600 mm.

Attach the Tecbor® side plates to the support stiffeners so that the joints between the plates overlap on a support stiffener. These Tecbor® side plates will be attached using metal brackets separated at intervals of 50 mm between plates.

A support stiffener will only be attached to the Tecbor® side plates for the beams, using metal brackets, on the lower face of the profile to be protected and formed with Tecbor® boards of 20 mm and 100 mm in width.

Attach the lower Tecbor® boards to the side ones and to the lower support stiffeners using metal brackets separated at intervals of no more than 100 mm.

Brackets of a length that is equal to or greater than the total thickness of the plates to be joined will be used; their minimum dimensions will be 35 x 10.6 x 1.6 mm.
