Anonymous users2024-01-24Is your living room a floor or a floor? If it is a ground ground, there is no need to park, and it is 6 8 cm thick. If you want to double as parking, then it should be 12 to 15 cm thick.
If it is a floor, the thickness of concrete is generally 12 to 15 cm thick. If the thickness is not enough, it is easy to crack damage.
You don't need to add beams, and the concrete strength grade is 25; PLATE THICKNESS 140MM; The steel bar is made of secondary steel bar (rebar attack balance stuffing), the diameter of the straight barrage section is mm, and the spacing is 120mm double-layer two-way.
It must be added, building mechanics pay attention to the force of the building must be balanced, otherwise the plate has such a large area, its own weight is very large, there is no beam, the center of gravity will be concentrated in the center of the real plate surface, coupled with gravity, and the gravity of human furniture, and the resonance reaction when walking, it is easy to collapse dangerously, can not meet the seismic requirements, belongs to dangerous buildings.
You don't need to add beams, and the concrete strength grade is 25; Plate thickness 140mm; The steel bar is made of secondary steel bar (rebar), with a diameter of mm and a spacing of 120mm.
THE FLOOR SLAB SINGLE AREA OF SQUARE METERS, IS ALSO A RELATIVELY LARGE LIVING ROOM, IT IS RECOMMENDED THAT THE THICKNESS OF THE FLOOR SLAB IS 120-130MM, THE STEEL BAR ADOPTS SECONDARY STEEL 10 TWO-WAY DOUBLE ROW (8 CAN ALSO BE, THE COST IS ECONOMICAL), THE SPACING IS 150-130, IN THE UPPER ROW OF THE FOUR CORNERS OF THE STEEL BAR IS ADDED TO THE SECONDARY STEEL 8 RADIAL REINFORCEMENT EACH 7, THE MIDDLE GENERALLY DOES NOT NEED TO ADD BEAMS, CONCRETE NUMBER C20-25, VIBRATING AND COMPACTING, WHILE THE PROTECTIVE LAYER OF UPPER AND LOWER REINFORCED CONCRETE MUST BE IN PLACE, AND THE EMBEDDED PIPELINE IS PLACED IN THE MIDDLE OF THE TWO ROWS OF STEEL BARS, Please refer to the above information for your own reference.
The beam height is generally about 1 10 of the span, and the width is about 1 4 beam height, and it is greater than the column width 2. The height of the overhead beam is about 1 4 of the span. Therefore, it is feasible to have h=750 and b=300 in the east-west direction, and h=500 and b=300 in the north-south direction, and the part of the beam should be h=350 and b=250. >>>More
