Residential design specifications, the floor load of 150KN, equivalent to 150 kilograms per square meter, the hotel's seafood pool are on the first floor ground. Residential floor thickness is generally 10CM, commercial 15CM. design considerations floor weight 400KG/M2, but also consider additional live load, generally 200KG/M2, the real calculation, respectively, need to multiply the coefficient of 1.2 and 1.4, the actual calculation of the floor of the load bearing capacity of 400X1.2+200X1.4=760. Extended information:
Floor slabs generally refer to a type of precast concrete part produced by precast yard processing. The load-bearing part of the floor level, which separates the house vertically into a number of floors and transmits vertical loads, such as people and furniture, and the self-weight of the floor slab to the foundation through walls, beams or columns. According to the material used can be divided into wood floor, brick arch floor, reinforced concrete floor and steel liner bearing floor and several other forms.
Role:
1., floor in the floor is mainly to bear the horizontal direction of the vertical load.
2, the floor can be in the height direction of the building is separated into a number of layers.
3, the floor is a wall, column horizontal direction of the support and contact components, to maintain the stability of the walls and columns, and can be subjected to the floor of the load together with the weight of the floor effectively transferred to the other supporting components, that is, the walls or columns, and then by the walls or columns to the foundation.
4, the floor sometimes also play a heat preservation, insulation, that is, enclosure function.
5, the floor can also play a role in sound insulation to ensure that the upper and lower floors do not interfere with each other.
6, the floor can also play a fire, water, moisture and other functions.
