The core tube is the center of the building, simply and clearly. The core tube is formed by the enclosure of elevator shafts, stairs, ventilation shafts, cable shafts, public toilets, and some equipment rooms.
The difficulty in the design of a 100-meter high-rise office building is the core tube, and the standard core tube is introduced and explained according to the 100-meter mainstream office products developed by the company
The functional space in the core tube is mainly composed of two parts: the room and its equipment room, and the tube well.
According to the requirements of the specification, the specific requirements of the room and its equipment room are: the required size of the shared front room is 10 square meters, the required size of the independent front room is 6 square meters, and the required size of the strong current room is 4 square meters; The required size of the weak current room is 5 square meters; The size of the door opening compartment in the bathroom is 900*1400mm; The distance between the toilet cubicle and the opposite wall or the edge of the urinal is 1100mm.
The tube well part has elevator shafts, toilet shafts, fire wells, front room air shafts, air conditioning wells, and reserved cooling tube wells in the computer room.
Among them, the elevator shaft ruler requires the size of 26*2.3m, elevator load capacity 1350kg
Toilet well 04 square meters; Toilet air shaft 5% of the indoor area of the bathroom; For 100-meter high-rise buildings, it is generally 08-1.1 sqm.
The positive pressure air shaft of the stairwell of the independent antechamber is 40% of the area of the stairwell + 24% of the area of the independent antechamber doorway. Press the front room door 1500*2100mm, stairwell 900*2100mm.
The positive pressure air shaft of the front room of the shared front room is 24% of the area of the door opening of the shared front room, and it is recommended to 08 square meters; Press the front room door 1500*2100mm.
The stairwell positive pressure air shaft in the shared front room is 40% of the stairwell door opening area, and it is recommended to 08 square meters; Press the stairwell door 900*2100mm.
The required size of the cooling tube well in the computer room is 900*450mm, and the required size of the cold and hot water tube well for air conditioning is 2800*600mm, which is suitable for Grade A office products. In the form of air conditioning, fan coil unit and fresh air system are adopted, and these two tube wells need to be added in the core tube.
