Description

Technical Field

[0001] The utility model relates to a building wall painting construction device, belonging to the technical field of building construction. Background Art

[0002] Plastering is a traditional decorative project that uses mortar to apply to the walls, floors, ceilings, and surfaces of buildings. In some areas of my country, it is also called "whitewashing" or "painting". Plastering refers to the systematic construction process of applying plastering mortar to the surface of the base material, which has the function of protecting the base and increasing the beauty, and providing special functions for the building. The plastering project has two major functions: one is the protective function, which protects the wall from erosion by wind, rain, and snow, increases the wall's ability to resist moisture, weathering, and heat insulation, and improves the durability and thermal performance of the wall; the second is the beautification function, which improves indoor sanitary conditions, purifies the air, beautifies the environment, and improves living comfort.

[0003] Traditional paintbrushes such as CN214329753U are wall painting equipment for building decoration and renovation. They are mainly composed of a roller, a support frame and a paint rod. When in use, the roller is moved against the wall by holding the paint rod with both hands. At present, most improvements on paintbrushes are focused on how to conveniently change the length of the paintbrushes; or how to paint the dead corners of indoor walls.

[0004] In actual construction applications, on wide walls, using a wider brush head can improve efficiency, while on narrow walls, a small brush head is required for flexible operation. However, in existing painting tools, the width of the brush head is fixed, so it is impossible to adapt to the above different application scenarios through change and adjustment.
