1. Core tube (1) The area of core tube accounts for about 30% of the usable floor area; (2) Mainly include: elevator (including fire elevator), evacuation stairs and smoke prevention stairs.
(1)10 ~ 15 square meters/person; (2) General office building: 5000 square meters/ton (3) Senior office building: 4000 square meters/ton (4) Super office building: 3000 square meters/ton (5) area calculation can be deducted skirt area and floor area without elevator;
3. Principles of Elevator Layout Principles of elevator selection and configuration: For different building types, number of floors, area of each floor, elevator parameters, etc., the configuration of elevators is also different. The configuration of elevators should conform to relevant specifications.
(1) Passenger elevators in each building or service area should not be less than two in case of peak passenger flow and maintenance needs. The two elevators should be arranged in parallel to facilitate control and mutual rescue in case of failure.
(2) Passengers in residential buildings take elevators at random, which may be smaller, but need to consider the handling of items (it is best to accommodate emergency stretchers). The reference number of tower type high-rise residence is 60 ~ 90 households.
(3) The sales point of the shopping mall or shopping center should mainly rely on escalators, elevators are used to connect the garage, office and so on. The number of escalators and elevators should be set at 80% ~ 90% of the traffic volume. In addition, there must be cargo elevators with approximately the same number of passenger elevators.
(4) The reference number of office building is 3000m2 ~ 5000m2. For an office building exclusively used by the company, elevators are not considered between adjacent floors, but between floors. As the number of service floors is reduced, the one-week running time of elevators is shortened and the conveying capacity is improved.
(5) The reference number of elevators used by hotel guests is one for 100 rooms. In addition must configure the special service elevator, the best way to set up dual use passenger and goods, to avoid service personnel, debris and guests mixed by the elevator.
(6) High-rise buildings can be divided into elevator service floors to stop, and traffic redistribution can be carried out through intermediate transfer floors. High-speed elevators can be used to give full play to high-speed performance in high-rise buildings. Some elevator shafts do not run from the ground floor to the top floor, saving the space occupied by the shaft plane.
(7) The cargo elevator should be close to the entrance of the cargo flow, and should minimize the intersection with the flow of people.
(8) Elevators provided by buildings should be concentrated in one area as far as possible, so that passengers can wait for elevators at the same place, so as to achieve the uniform distribution of passengers to elevators. When building entrances and exits are on the second floor or above, escalators can be used to connect the traffic between the entrance floors so that the starting floors are concentrated on the same floor.
(9) Arrangement of passenger elevators. In order to facilitate the use of elevators during maintenance, the elevators shall be arranged in pairs; Of course, more than a pair, such as 3 for a group can also be, but better not more than 3 horizontal.
(10) The group control of elevators can give full play to the efficiency of elevators, but not more than 4 elevators, which are better to be faced with two of each, and 4 in a horizontal row is not ideal. Because there is a disadvantage of group control, that is, sometimes the elevator people just finished entering, the door just closed, someone outside presses the signal button, the door automatically opens, causing multiple switches, so the group control elevator should not be too much.
(11) Design of short walls on both sides of elevator doors
(1) do shear wall seismic processing, so the wall is thicker, causing visual obstacles when users wait, often can not see the far end of the elevator door to the station to open, until someone found in the past, the door has been closed, feel special trouble.
(2) The design of the hall door expansion hole is reserved, the control panel base is reserved and the signal box is reserved. If the shear wall has a fatal impact on the model selection and change, it will increase the construction difficulty.
(3) in fact, as long as the wall is not designed into the thick aseismatic wall, and the design into the filling wall, will be much thinner. Moreover, there are many openings in the wall, which will not play a big role in the earthquake. Furthermore, after the wall is changed into a filling wall, the signal box of the elevator will not be affected by the model of the elevator manufacturer.
(12) For the elevator groups in the upper and lower zones, as the elevator in the lower zone is not used above, it can be turned into a large room, which can be used as a meeting room or database, to increase the recovery of investment, and so on.
