Personal defense project floor area means that in the process of building construction, should be based on the size of the building area, according to the provisions of the construction of human defense works, human defense works occupied by the floor area of the human defense project floor area.
There are the following provisions for the area of human defense works:
All buildings are categorized according to the form of construction, and the calculation of indexes has nothing to do with the function of use. Calculation method:
1, more than ten floors (including ten floors) of the building, should be constructed "full of red" air defense basement, can be calculated according to the standard area of the tenth floor indicators;
2, ten floors (excluding ten floors) below, the foundation of the depth of more than 3 meters (including 3 meters), should be built according to the area of the area (including the ground floor) of 3%;
2, ten floors (excluding ten floors) below, foundation depth of more than 3 meters (including 3 meters), should be built according to the area (including underground) of the Construction;
3, ten floors (excluding ten floors) below, the foundation depth does not exceed 3 meters of the building, should be built according to its area (including underground) of 2%;
4, a single construction project (above ground outside the projection range of the building underground) should be built according to its area of 30%. If a building has both high-rise and multi-storey, the building should be vertically divided according to the above requirements, and then categorized to calculate the area index of human defense should be built.
Expanded:
Engineering design
Air-raid basement professional team engineering, personnel sheltering engineering design, should be sheltered area in accordance with the "norms" Table 3.2.1-2 "area standard "Determine the number of sheltering personnel or equipment, not allowed to arbitrarily raise the" area standard "resulting in the number of sheltering personnel or equipment to reduce the number of entrances and exits caused by the width of the protective equipment and wind, water and electricity professional design parameters are small, to meet the actual needs of wartime.
Personal defense materials library project should be based on the storage of food, materials, materials, the minimum width of the entrance and exit door 1.5m, for the construction area of more than 2000m protection unit of the main entrance and exit of the materials library should be considered into the forklift, the design drawings should be clear on the vehicular access, the width of the vehicular access to meet the requirements of the passage.
The main design should be classified according to the material open stacking design, each stacking section length should not be greater than 15m, the spacing between the two stacking area should not be less than 800mm, the distance between the material and the wall should not be less than 700mm, and the distance from the bottom of the beam should not be less than 300mm.
The design drawings should be clear on the dimensions of the stacking area, the stacking area stacking of food, the type of material (food type, specific gravity). Can be used in accordance with the "Code for Structural Loading of Buildings" (GB 5009-2001) in Appendix A, Table A.1 & lt; commonly used materials and components of the self-weight table & gt; item 9 "food").
The effective area of the diesel power station should be determined by the following standards: <200kw power station by 1.18 ~ 1.68m/kw; 200 ~ 1000kw power station by 1.26 ~ 1.50m/kw; >1000kw power station by 0.67 ~ 1.26m/kw.
The scale of medical ambulance works according to the "norms" Table 3.2.1-1 according to the effective area to determine the ambulance station is generally designed according to 1 protection unit, first aid centers should be designed according to 2-3 protection units, central hospitals should be designed according to 4-6 protection units.
Calculation of area
The calculation of air defense basement floor area, effective area of human defense, shelter area.
The air defense basement building area, is referred to here by the air defense basement directly under the impact of fluctuating loads on the components of the enclosed space area, that is, by the outer wall of the air defense basement, the air wall, protection of the closed door (explosion-proof wave live door) door frame wall, blocking wall, protective partition wall formed by the enclosed space area.
Airproof basement outside the mouth of the channel, shafts, stairs, ducts, etc. can not be counted as air defense basement floor area. Effective area of air defense refers to the area to meet the use of personnel and equipment, the value of the air defense basement floor area and the difference between the structural area. Human defense shelter area is the effective area of human defense for sheltering personnel, materials, vehicles.
The value of the effective area of human defense minus the area of the following parts of the use of the area:
1, the mouth of the room, anti-virus channel, the area of the closed channel;
2, ventilation, water supply and drainage, power supply, chemical defense, communications and other professional equipment room area;
3, toilets, lavatories, boiler rooms and other areas.
Safety
In terms of safety, it can be said to be well thought out, 50-centimeter-thick reinforced concrete and fully enclosed channel design, a full set of ventilation ducts, whether it's a flood or a war, the people's air-raid basement is basically foolproof.
