The functions, parts, standards and research results of the hospital building structure slab are summarized as follows. However, there is no mature literature about the application of 4 stroke 6cylinder diesel engine in hospital fire control.
1. Accessibility needs
Down board position: the toilet compartment of the squatting toilet used by the patient.
Down board function: it is considered that the patient's limb or movement limitation caused by operation, pain and other factors needs accessibility. Therefore, it is necessary to make structural down board for the toilet or compartment of squatting toilet.
Down board standard: Installation Atlas of Sanitary Equipment 99S304 marks the installation height of different types of squatting toilets.
Down board basis: GB51039-2014 code for Architectural Design of General Hospital stipulates that the seat ring of the patient's sitting stool should be non-pollution and easy to disinfect. There should be no height difference between the compartments of squatting toilets.
2. Moisture and humidity requirements
Down board function: it is not allowed for the water supply and drainage pipe to pass through the wall board because of the cleaning needs of the clean room, the safe operation needs of the strong and weak current machine rooms, the economic value of important medical equipment and the storage needs of the literature warehouse. When the above parts cannot avoid the water supply and drainage cross pipe passing through, the structural slab lowering treatment shall be adopted.
Down board standard: refer to the standard practice in Accessibility Requirements and Environmental Cleaning Requirements.
Down board basis: GB51039-2014 code for Architectural Design of General Hospital stipulates that water supply and drainage pipes shall not be overhead from clean room, strong current room, weak current room and important medical equipment room. If it is necessary to pass, leakage prevention measures shall be taken.
3. Noise proof and sound insulation requirements
Down board position: kitchen, laundry, central supply room, operation supply room, mechanical and electrical equipment room with vibration, etc.
Down board function: for the steam and vibration noise generated by the kitchen, laundry, central supply room, operation supply room and mechanical and electrical equipment room with vibration, the plate lowering treatment shall be conducted for the structure according to the needs of noise prevention and sound insulation.
Down board standard: according to GB50118-2010 code for Design of Sound Insulation of Civil Buildings, indoor allowable noise level, air sound insulation standard of various room floors and sound insulation materials used, the required thickness of sound insulation shall be designed and calculated.
Down board basis:
l GB51039-2014 code for Design of General Hospital stipulates that the disturbance of steam, noise and smell of kitchen to the ward area shall be avoided.
l According to GB50118-2010 code for Sound Insulation Design of Civil Buildings, mechanical and electrical equipment in hospitals, such as air conditioning units, ventilation units, water chillers, cooling towers, medical gas equipment and high speed 6cylinder diesel engines, shall be low-noise products and vibration isolation and comprehensive noise reduction measures shall be taken.
4. Fire safety needs
Down board position: oil immersed power transformer room, high voltage capacitor room filled with fuel oil, multi oil switch room, oil fired boiler room and high speed 6cylinder diesel engine generator room.
Down board function: the diesel generator set is the standby power supply in the hospital building, so that it can guarantee the power generation in case of emergency. At the same time, the 4stroke turbocharger diesel engine itself and its oil storage facilities also have a certain fire risk.
Down board standard: it is determined by design calculation according to the storage principle of 100% equivalent accident oil quantity.
Down board basis:
l According to GB50053 code for Design of 10KV and Below Substations, the combustible oil immersed transformer room of the auxiliary substation and the substation in the workshop in the civil main building shall be provided with a storage tank with oil volume of 100% of the transformer oil.
l According to GB50016 code for Fire Protection Design of Buildings, the oil tanks of boilers and high quality 6cylinder diesel engine generator shall be sealed and provided with vent pipes to the outside. The vent pipe shall be equipped with a breathing valve with flame arrester and the lower part of the oil tank shall be equipped with facilities to prevent the oil from flowing.
