steel longheroni dimensioning board for small mezzanine

[odisseo 18]

hi, I'd need a tip, I should dimension the current support longheroni to create a châssis frame to make a small loft
the frame will affix on a 12 cm thick perforated brick masonry, on 2 parallel walls 2,10 meters high, the intersection between the beams is 120,150 cm, I can put 3 max 4 longheroni as I recommend to dimensional everything, the floor I think will make it in wood from carpenters, how do I realize a simple frame of support for everything? thanks to who will help methe length of the beams is
a 2,46,m
a 2,30 m
a 2,16 meters
one I have to dimension it and create a anchoring support on the wall, which aduced section, which other elements add

questions:
1) How much weight do you have to hold on to the loft? What are you doing?

2) to evaluate the support on the wall. if the load is not sufficiently distributed it breaks the brick row below. So the perforated bricks hold, or do you need a system to distribute the load?

3) where do you fix the beam to the wall, how is the wall? if you tilt as from your scheme and there are the classic light perforated blocks, the seal will be very low. If there is a beam in c.a. It will be a mess to put the dowels.

4) to evaluate how to support thrusts in case of sisma. a frame made could have problems in case of horizontal thrusts. to be evaluated seismic area.

p.
It is obvious that everything should be calculated and verified by a qualified and qualified technician, with all the necessary documentation. therefore all I say is purely for purposes of curiosity / teaching.

practically on one side is resting on a wall thick 13 cm, on the other welded on a 140 ipe already welded, the plate fixed it is near the pillar, I had thought or boxed 80x40 x 3 mm; boxed 90x50x 3 mm or ipe 80 mm; the flow is indifferent, it would be a mezzanine obtained from a former technical room, to be used as a storeroom or clearing room, the floor I think I will make it in carpentry timber, then if everything works I should make a proper ladder, thanks for your intervention
on the net I have seen that some user has used pipes dalmine joints and lumber of carpentry recovered in the construction yards, solution spartana to economic, I do not know how much carry in term of load

for the part of metal constructions and joints you will find everything on eurocode 3 uni en 1993.
As for bricks and bricks I recommend a good manual of constructions for architects or geometries. You don't have to pass the compression load. traction and bending the bricks do not hold sufficiently. Therefore if you have to tie a beam of iron to a wall you have to insert poles with welded large plates on which weld the beam. this to distribute the load. it may also be necessary to make pass-by loops.

But then who certifies the thing? Isn't one falling and hurting? then there are civil and criminal responsibilities.
attention to the things built to the best....no?!? ! ? !

thanks to all the right tips I will treasure, I have taken 2 canned 80x40x2 mm we see how it develops everything I will let you know you have been precious

 

[odisseo 18]

I soldered everything, I used 2 boxed 80x 40 x 2 mm galvanized, welded everything, wall bracketed anchor plate with 8 mm diameter fisher pins, to the eye if I made the structure well how could I load it? Afterwards I will give a pass to the welds x safety I will save you of coast of the angles x create the frame done to collect the table, what I recommend, thanks again x collaboration

 

[odisseo 18]

excuse me if I ask again your precious intervention, the beams I installed (boxed 80x40x2 mm galvanized) I should build and install access ladder what you recommend to me to do? I have little useful space to manoeuvre allego schematic plan
thank you again excuse me if I am petulous
you would have ideas or suggestions thanks again

ladder made with boxed 60x 40 for lateral stretches and 50x30 for pioli, for flat orsogril use or what? thanks for the attention

I have difficulty understanding what you intend to do and what your doubts are. is it possible to add a drawing / scheme?

 

[odisseo 18]

like thisthe first beam is 190 cm the second to 120 cm of interaxis is 200cm, the third to 118 cm is long 215 cm the fourth to 120 cm long is 228 cm long, resting on one side on ipe from 140 , on the other on masonry under I have 2 meters above about 180 cm , I have realized access ladder now I should realize the floor of support, what do you say? Thank you.

You don't understand anything.
Regardless of the specific situation, the griddling plan (orsogril) is the best solution, at equal load there is no structure that is able to compete, unless to complicate all the distribution of the beams.
attention that the grilled panels have a max size in width of 1000 ( x 6000 max ) and have a sense of laying to have the indicated flow rate on the catalog.
