Generally one of the best types of ceiling in terms of technical and performance in the whole world is waffles ceiling. But the necessity of implementation of false ceilings also implementation of formatting in this ceiling, increases the cost. Also control of bar is difficult and may be covered from eyes, which these are another reasons for the lack of interest for this ceiling. It is shown that moment throughout span change direction in fixed span so the best option for one way ceiling and two way ceiling are beams with I-shaped sections that generally fix the problems and disadvantages of the T-shaped section. I-shaped sections have the maximum moment, minimum weight, slip and Sound transmission.in this floor there's no need for false ceilings and formatting. In order to achieve mentioned structural shape use different blocks and mold.
1- Using I-shaped sections in waffles ceilings have separated completely this ceiling from the current waffles ceilings.
2- As in claim 1, I-shaped sections can be applied with different dimensions and geometry in section (FIG. 3).
3- As in claim 1, the main innovation is ceiling structural shape that can be implemented by different methods.
4- I-shaped sections as in claim 1, have the maximum moment, minimum weight, slip and sound transmission. To make this structural section different blocks and molds can be used.
5- There are especial spacers considered to be used for reinforcing the ceiling which solve completely form working problems.
6- As in claim 5, the pins in mentioned ceiling are embedded, in a way that implementation errors go down to zero, so workers can implement it easily.
7- As in claim 5, implementation errors reduce to zero and theoric calculations match with implementation.
8- As in claim 5, the spacers are designed with special location that passes through longitudinal and reinforcement bars.
9- As in claim 5, bottom element of Spacers is fireproofing and resistant to transmission of fire.
10- According to claims 1 and 4, usage of blocks;
11- As in claim 4, to create this structural shape, the different blocks or molds can be used. These blocks can be implemented as follows:
12- As in claims 5 and 11, designed pins on spacers are located inside the holes which are embedded on the blocks
13- As in claim 4, undersides of blocks are cut like an arc or on a slant or etc. So after concreting, concrete penetrate under this section and maintains blocks stability
14- As in claim 11, using a combination of polystyrene and gas concrete blocks in the ceiling, increases the resistance to fire and earthquakes and reduces the weight of the ceiling. Due to the porous blocks, this ceiling is an appropriate soundproof and thermal insulation.
15- Reduction of beam deflection in simple span (35%) and reduction of beam deflection in fixed span (41%) comparing to current ceiling waffle.
16- 10% increase in moment capacity in simple spans and 80% increase in moment capacity in fixed spans comparing to current waffle ceiling.
17- Weight of ceiling is reduced about 20% and it has become economic much more.
