>I didn't say but, we (group of students) soldered all the "holes" (sda,
scl...) with a comb-like metal (like this ++++), so that the pins one side
coming from sensor enter the cablet whose other side connects to right pin on
Rpi. This is our problem (I 
think it is the thinnest of all the problems :-) but we're still beginners), a
cablet is for 1 sensor but the pins on Rpi are only 2... What is needed is a
"multicablet": 1 end to the Rpi,
>that divides in more ends at the other side, so the sensors can share the
communication with the processor

What type of RPi do you have that you had to solder to it? All of mine came
with a set of pins for connecting jumper wires

(depending on what type of ends you need)

and a breadboard (for solderless development and component reuse)

or proto-board (for soldering a more permanent project -- these have copper
in the same arrangement as a breadboard, so when the project works you just
move the components to the same position on the proto-board and solder
them)

And here is one meant for direct jumpering of an RPi
