Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, and more specifically to a spraying device for construction engineering. Background Art

[0002] In the field of construction engineering, spraying is a crucial construction process, which is widely used in the decoration and protective coating construction of walls, ceilings and other building structure surfaces. This process involves spraying various functional or decorative materials such as paint, fireproof materials, and thermal insulation materials evenly on the building surface, so as to achieve the dual purpose of beauty and protection of building structure.

[0003] In actual construction scenarios, as the height of buildings continues to increase, spraying operations face huge challenges. At present, when spraying tall buildings, extended spray pipes are often used to assist construction. This special spraying device can improve the spray coverage of the surface of higher buildings to a certain extent. However, this design based on extended spray pipes has obvious limitations. Due to the long spray pipe, its control flexibility is greatly reduced. Especially when spraying complex corners such as corners and edges that are prone to appear at high places, it is difficult for operators to accurately control the spraying direction and angle. This not only causes the spraying material to fail to accurately cover the target area, resulting in material waste, but also often causes uneven spraying, which seriously affects the aesthetics and protective effect of the building surface. What's more serious is that in some extreme cases, due to the inability to effectively control the extended spray pipe, some complex corners cannot even perform normal spraying operations, thereby affecting the construction progress and quality of the entire construction project, and increasing the construction cost and time cost. For this reason, we propose a spraying device for construction engineering. Utility Model Content
