Code for fire control design of steel structure workshop

1. Apply fire retardant coating to steel structure: in the whole process of fire protection design specification, suitable fire retardant coating must be selected according to the characteristics of steel structure engineering construction. Under general conditions, industrial buildings, large and medium-sized commercial construction of heavy steel structure, must use fire retardant coating to develop fire safety, to master the building fire rating, prefabricated members have fire rating, more appropriate to use thin form of fire retardant coating. If building structure position has taller adornment design regulation, also must choose light and thin architectural coating. In terms of fire retardant coating, it is necessary to carry out fire prevention experiments according to the details of steel structure prefabricated components, so as to establish the thickness of its coating, promote the promotion of fire retardant coating, and give full play to its fire safety effect as soon as possible.

2. For steel structure spray paint polyurethane foam fireproof paint, carry out business outsourcing fireproof layer maintenance: in terms of polyurethane foam fireproof paint, belongs to one of the fireproof coating, composed of a variety of elements, for example, film forming agent, foam, it is different from the role of general paint. In the steel structure coated with appropriate polyurethane foam fireproof paint, will produce a layer of paint layer on the surface, no flammability. Even if there is a fire accident, it can slow down the ignition rate of combustible building paint, have fire safety maintenance, prevent the rapid spread of fire, maintain the building structure, fight for a lot of fire fighting time, minimize the damage. In addition, in the fire design specification, appropriate countermeasures must be adopted according to the characteristics of the steel structure, such as surface painting method, casting board forming method, effectively solve the outsourcing fire protection layer, plus external insulation layer.

3. Steel structure plant entrance and exit fire design code: for a single project building, it is necessary to establish the specific address of the fire safety zone safety channel, the actual total number of safety channel. In the design process, also want to comprehensive considering the industry in each point of the plant and safe passage in the middle of the actual spacing, carefully examine and approve the size of the evacuation door, location, see if it and the relevant requirements, should also be objective to analyze the fire evacuation and further work halfway point in the middle of the span, be sure to give full consideration to the specific route, to carry out accurate measurement, Instead of just measuring the straight-line distance, minimize the evacuation distance of staff to prevent the lack of indoor stairs.
