Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction, in particular to a spraying device for building structure and a spraying method thereof. BACKGROUND

[0002] In building construction, spraying is to disperse paint into uniform and fine mist droplets on the surface of the coated object by means of pressure or centrifugal force through a spray gun or a disc atomizer. Spraying can be divided into air spraying, airless spraying, electrostatic spraying and various derived ways of the above basic spraying forms, such as high-flow low-pressure atomizing spraying, thermal spraying, automatic spraying, multi-group spraying, etc. In building construction, the interior or exterior surface of the building needs to be sprayed for protection, such as spraying real stone paint on the exterior wall. When spraying, a spraying device needs to be used for spraying operation. Especially when spraying on the exterior wall of the building, the current process often adopts a basket type, in which a worker stands inside the basket, then pressurizes the inside of the spraying material, so that the spraying material is sprayed out of the spray gun in the worker's hand and sprayed on the building surface to complete the spraying effect.

[0003] Some existing spraying devices (such as Chinese patents CN107989337A, CN110439226A, CN112681680A, etc.) have construction dead angles and still need manual spraying. When the construction personnel perform manual spraying, they often cause overexertion of the arms due to long-time holding of the spray gun, which has a large working intensity. In long-time operation, the labor efficiency is reduced, which is inconvenient to use.
