New steel structure second-floor platform added to the factory building
Thread Content
If it is desired to add a steel structure platform on top of the existing single-story factory building, the following parameters are known: 1. The factory building measures 72m * 18m, resulting in an area of approximately 1300 sqm. 2. The second-floor platform will be used for storing goods, with each square meter requiring a load capacity of about 1 ton. 3. The second-floor platform will also be used to house equipment (2 tons per unit * 5 units), two of which are equipped with electric motors for mixing. I would like to ask the experts: 1. Is it possible to insert rebar at the columns of the original factory building to support the second-floor platform? ； 2. If it’s not possible to do it in one step, can we simply build the foundation on the existing ground or by digging a new pit, and then use columns for support in order to create a second-level platform? ；
This needs to be recalculated.
Renovating an old factory building doesn’t require a new production license; it shouldn’t be regulated, right?
It’s not that it can’t be done; the factory building involves fire hazards and fire separation zones, which are matters related to fire safety. There’s also the issue of whether hazardous chemicals are involved, which falls under occupational safety regulations. Additionally, the stress on the original columns and beams after adding another floor is a concern related to civil engineering or steel structure design.
But the prerequisites for the license have to be taken into account; that’s part of the design process. If it is a hazardous chemical, it depends on what the safety assessment says.
1. This falls under the category of renovation projects; it depends on the **local conditions**, so it’s best to seek advice. The work safety supervision agency is generally in charge of such matters. 2. Based on your general description, I’m not sure about the load-bearing capacity of your columns ； However, the additional weight needed is not large; with an average weight of 1 ton per square meter, it is possible to construct steel beams using chemical anchor bolts. Reactors with a weight of one or two tons pose no problem at all.
It is necessary to assess the roof of the existing factory building; based on your description, if 1 ton per square meter is required on the second floor, it is likely that the existing structure needs to be reinforced. If Option 2 is chosen, it depends on whether there is space for the columns to be installed.
