Project ponents are: two office buildings, construction area is 70800m2, 28 layers, the standard story is . 2 Load Calculation 1) Load characteristics: electric load, much larger than the national civil engineering technical measures Large 120W/m2 indicators, especially in the electricity load more food, and different types of food and beverage catering different cultural backgrounds also high. 2) the uncertainty of a large load, because the mercial real estate rents are often based on market demand, and constantly adjust the nature of the shops, making the load in the dynamic changes. 3) There is no specification and technical measures in the different types of mercial projects refer to the detailed parameters of the shops, engineering design load calculation in the lack of data, in most cases to rely on staff with previous experience in engineering design calculations. Load the selection of parameters: for the above problems, the load calculation, the first developer of sales and good munication, to determine the form of layers of the forms and nature of floor area, which is calculated on the basis of electrical load basis。 followed to determine parameter index within the unit area of shops is also very important and plex because there is no clear indicator of the specification can refer to。 bus carrying capacity for the 1000A, this road can meet the maximum 1000A current load requirements, even if there is adjustment, power distribution switches and circuit can not make big changes. 6 layer distribution box set According to the division of layers of fire protection district, respectively numbered as A ~ K layers within the set level shaft for the retail lighting power distribution box, with one on one power supply shops in radial power. Should be noted that the forms of the plex layers of layers of fire partition, does not correspond to the lower, making some of shaft power in charge of the fire district at the same time, also responsible for the power supply adjacent to the fire district. At design time, using the principle of proximity, while also taking into account the burden of the whole trunk load conditions, so that each shaft as far as possible a more balanced load. 7 public area distribution box set Taking into account the future needs of the business redecoration of public areas must be reserved for power.
