Carrier elements, the thickness of which is smaller than the other two dimensions and loaded in the direction perpendicular to the plane, are called floor (platter).
Duties of Floorings:
- It is to transfer the permanent and moving loads acting on them to the columns they are supported.
- In case the building is exposed to earthquakes;
- The effect of earthquake accelerations is to transfer the inertial forces of the masses to the vertical carrier elements.
- While transferring the earthquake loads to the vertical carrier elements, it is to allocate these loads to the vertical bearing system elements according to their rigidity.
Parameters Effective in Flooring (Platter) Selection:
- Seismicity of the region
- The cost of the flooring
- Openings to be passed
- Amount and type of load to act
- Purpose of the building
- Plan geometry of the building
- Sensitivity of the goods and devices it will carry
- Knowledge and skills of technical staff
Types of Floor:
- Girder Floor:
In case one or more edges of the floor is supported with beams, this floor is called beam floor. Girder slabs are divided into two classes depending on the ratio of long edge to short edge.
2. Frameless Floor:
Beam-free Flooring are systems in which vertical loads acting on them are transferred with continuous plates equipped in two directions, which are supported directly to vertical carrier columns and curtains without beams in between. Generally, the desire to use the places comfortably and effectively is effective in choosing the flooring system without beams. Beam-free floors are divided into four different types.
- Beam-free flooring without tray and header
- Plate-free beam flooring
- Headed beam-free flooring (cork flooring)
- Headed and platter-free flooring
3. Gear Floor:
The flooring consisting of teeth and a thin table with a free span not exceeding 70 cm is called toothed flooring. Threaded floors are particularly suitable for situations where the clearance is large. Toothed floors are classified as toothed floors running in one and two directions, similar to beamed floors.
- Gear laying running in one direction
- Unfilled toothed flooring (ribbed flooring)
- Filled block toothed floor (hollow floor)
- Gear floor running in two directions (cassette flooring)
Beam-free floors provide efficient and comfortable use of spaces as well as heat and sound insulation compared to beamed floors, but are more likely to be stapled. In addition, the earthquake performance of both toothed floors and beamless floors is worse than that of beamed floors.
