The present invention relates to an air column and a cover body coupling structure of a multi-purpose air dome house, and more particularly, a configuration of an air column to a tube, a first shell, a second shell, a third shell, etc. are sequentially combined with a multi-layered outer peripheral surface This prevents the tube from bursting and is provided on the outer periphery of the air column, making it easy and convenient to combine the cover body to block foreign substances from the external environment, and at the same time, ventilation facilities are installed on the cover body to improve ventilation efficiency. It is possible to maximize and eliminate the problem that the cover body is damaged or removed by the external environment, thereby reducing production cost and easy installation and disassembly. It relates to the air column and cover body combination structure of a multi-purpose air dome house with excellent economic efficiency. Specific solution means of the present invention, "The two grooves 100 formed in parallel in the longitudinal direction at a depth of 30cm on the ground and both ends of the grooves 100 are inserted at a predetermined distance to form an arc. As air is injected, it has a cylindrical shape by air pressure. A cover-type cover body 300 in which vents 310 are formed by zippers on both sides of the arcuate air column 200 forming the arched air column 200 and the outer circumferential portion where the arcuate air column 200 is formed, and both ends in the longitudinal direction of the cover body 300 A pipe 520 provided with a water spray nozzle 510 long in the longitudinal direction is formed outside the uppermost end of the fixing bracket 400 and the cover body 300 for fixing and combining the key, and the pipe 520 stores water In a state consisting of a multi-purpose air dome house consisting of a water spray unit 500 connected to the tank T and capable of spraying circulating water pumped from the water storage tank T, the a
