As an indispensable vertical transportation tool in modern buildings, the design, manufacture and installation of elevators are inseparable from accurate load mass calculations. The load quality of the elevator refers to the maximum weight that the elevator can safely carry, and this parameter is directly related to the safety and function of the elevator. This article will delve into the calculation method, influencing factors and application of elevator load mass in architectural design.
Calculation of the load mass of the elevator.
Basic calculation formula.
The basic calculation of the load mass of the elevator follows the principles of mechanics in physics and is mainly based on the following formula:
q = a \times n \times p \]
Wherein: q ) represents the load mass of the elevator (kg);
a) represents the area required for each person (usually 0.).7 to 10 sq.m.);
n ) represents the rated number of passengers of the elevator;
p ) represents the average mass of each passenger (usually calculated on a standard of 68kg).
Determination of the number of passengers in capacity.
The rated capacity of an elevator is related to the function of the building, the size and type of elevator. Elevators in commercial buildings typically require greater capacity to handle peak hour passenger flows, while residential elevators adjust based on occupancy and frequency. Elevator manufacturers will provide different models of elevators with standard rated capacity for selection.
Consideration of area requirements.
When calculating the load mass, the actual area of the elevator car must be taken into account. The interior dimensions of the elevator must be able to comfortably accommodate passengers, while leaving enough space to prevent congestion. The internationally adopted standard for per capita area is 07 to 10 square meters, but this standard will also be adjusted according to the actual situation.
Factors affecting the load quality of the elevator.
Type of building. Different types of buildings have different load requirements for elevators. For example, hospital elevators need to consider the size and weight of patient beds, while freight elevators need to be designed based on the size and weight of goods.
Frequency of use. Elevators that are used at high frequencies often require higher load mass to cope with constant operating pressure, thus ensuring long-term stable operation.
Safety. When calculating the load mass, the factor of safety must also be taken into account. Normally, in order to ensure safety in the limit state, the actual load capacity of the elevator is higher than the calculated load mass.
The application of elevator load mass in architectural design.
Reasonable planning of the number and layout of elevators.
In the early stage of architectural design, by accurately calculating the load mass of the elevator, the number and layout of the elevator can be reasonably planned to meet the use needs of the building.
Determine elevator specifications and models.
The calculation of the load mass will directly affect the selection of elevator specifications and models, including the size of the car, the width of the door, and the associated drive system.
Influence the design of building structures.
The load quality of the elevator will also affect the design of the building structure, especially the load-bearing capacity of the elevator shaft and the layout of the elevator machine room.
Meet the needs of different uses.
In different buildings such as commercial centers, residential areas or industrial areas, the load mass of the elevators will be adjusted according to the respective usage needs. Search Topic Full Time Challenge March
The calculation of the load mass of the elevator is a key link in the design and manufacture of the elevator, which is directly related to the safety performance and efficiency of the elevator. By accurately calculating and applying the load mass, the optimal use of elevators can be achieved in building design and operation, ensuring safety, efficiency and economy. With the continuous progress of building technology and the diversification of user needs, the calculation and application of elevator load mass will continue to develop to adapt to a more complex and changeable building environment.
