What is the most reasonable design for mobile shelving in an archive room?

According to the national standard 50009-2001, Code for Loads on Building Structures;

What are the load-bearing requirements for mobile shelving units storing a small number of items? For a small number of items, the minimum load-bearing capacity should be 600 kg/m². What are the load-bearing requirements for mobile shelving units storing general items? For general items, the minimum load-bearing capacity should be 800 kg/m². What are the load-bearing requirements for mobile shelving units storing heavier items? For heavier items with a larger quantity, the minimum load-bearing capacity should be 1200 kg/m². The floor requirements for mobile shelving units depend on the actual weight to be stored. Larger professional archives must strictly adhere to national standards. What is the approximate self-weight and load-bearing capacity of a typical mobile shelving unit? The self-weight of a mobile shelving unit is 70 kg/set, with a maximum design load of 480 kg, for a total weight of 550 kg (this is the maximum weight that will not be exceeded when storing general archives; other special items will be calculated separately). To arrange mobile shelving units in an archive room, first, you need to know the length and width of the mobile shelving units, consider the door positions, and then arrange them. The length and width of the mobile shelving units can be used to arrange the column length and width of the mobile shelving units. For example, if a room is 7 meters long and 4 meters wide, and each set of mobile shelving is 0.9 x 0.5 meters (height not considered), then you can arrange 0.9 meters in the 4-meter direction, making 3 sets per row, occupying 3 x 0.9 = 2.7 meters of space. Leave 4 - 2.7 = 1.3 meters for a walkway. Arrange columns in the 7-meter direction, reserving 1 meter for the track length, leaving 6 meters. 6 meters can accommodate 6/0.5 = 12 rows. Therefore, this 28-square-meter room can hold 3 sets/row * 12 rows = 36 sets. Alternatively, you can arrange 0.9 meters in the 7-meter direction, making 6 sets per row, occupying 6 x 0.9 = 5.4 meters of space. Reserving 7 - 5.4 = 1.6 meters for a walkway, leaving 1 meter for the track length in the 4-meter direction, leaving 3 meters, which can accommodate 3/0.5 = 6 columns. With this arrangement, the room can store 6 sets/row * 6 columns = 36 sets. Number of mobile shelving units needed for a 100-square-meter archive room: Approximately 120 sets. Cost of installing mobile shelving in a 100-square-meter archive room: Approximately 100,000 to 150,000 RMB. Arrangement of a 100-square-meter archive room: Select the specifications and dimensions of the mobile shelving units based on the type of archives you store, and arrange them reasonably according to the room's length and width. Production time for a 100-square-meter archive room mobile shelving unit: Normal factory production time is approximately 10-15 days, and installation time is 5-7 days. The normal construction period from order to completion is generally around 3 weeks. If you have any questions about the arrangement, detailed configuration, delivery, installation, or purchase price of the mobile shelving units, please feel free to contact Yiwu Mobile Shelving manufacturer.
