Description
Technical Field
The invention relates to a building spraying system.
Background
The steel structure factory building mainly means that main bearing components are made of steel. Including the steel post, the girder steel, steel construction basis, steel roof truss (certainly the span of factory building is bigger, all is steel construction roof truss basically now), the steel roof, the wall of noticing the steel construction also can adopt the brick wall to maintain. As the steel yield of China is increased, steel structure plants are mostly adopted, and particularly, the steel structure plants can be divided into light steel structure plants and heavy steel structure plants. Industrial and civil building facilities constructed from steel are known as steel structures.
The steel structure factory building has the characteristics of light weight, high strength and large span of the steel structure building 1. 2. The construction period of the steel structure building is short, and the investment cost is correspondingly reduced. 3. The steel structure building has high fire resistance and strong corrosion resistance. 4. The steel structure building is convenient to move and is free of pollution during recycling.
The ceiling of steel construction factory building mainly adopts the covering of various steel sheet or other structures to constitute, its ubiquitous problem is exactly that the heat-proof quality is relatively poor, in factory building production operation, because the insolate of outside sunshine, can lead to the temperature rise in the factory building, traditional cooling measure, need maintain the operation of high strength, just can maintain the temperature in the factory building in a comfortable within range relatively, consequently, the energy consumption is higher, in order to guarantee cold insulation performance simultaneously, also lead to the ventilation that the factory building can not be nimble when summer, lead to the air in the factory building muddy, it is unfavorable to workman's health.
Based on the problems, the building spraying system is designed, the ceiling of a factory building can be improved and upgraded, good heat dissipation effect can be achieved in summer, and the temperature in the factory building is effectively reduced.
