You'll need to anchor those beams to the wall using minimum 100mm Ramset galvanised anchors. 500mm spacing will suffice. Make sure you leave a gap between the beam and the brickwork to allow drainage.

Thanks Pete can i use wall plug for anchors n flat square washers give gap between beam and wall aprox 10 ml also how many anchors can be use for 3.3 meter. Much appreciated

The Ramset anchors I linked you to include the wall plugs.

Washers work, they just need to be a decent size because when you tighten the timber to the brick wall, the washers get compressed into the timber and you lose the gap. You can use thin slices of H3 timber as spacers.

3.3/0.5=6.6 so you'll need 7 spaced roughly 500mm apart.

Awesome stuff from the always awesome @ProjectPete
@Ammy , couple of things you might find handy as you're going down onto such a solid surface...
The Good Times decking system can be really handy as it's modular. The legs etc. are ideal even if you're building your deck from scratch. The legs are adjustable so makes getting everything level heaps easier.
These Tuffblocks are also super useful in a situation like yours as they can be used a number of ways and provide good moisture separation between timber and slab.
