Ceiling paint-brushing device for building construction

Abstract

The invention discloses a ceiling paint-brushing device for building construction and relates to the technical field of building construction. The ceiling paint-brushing device comprises a brushing unit and a supplying unit. The brushing unit comprises a shape-fixing rolling device and a brushing device; the shape-fixing rolling device comprises a cylindrical elastic bag; a circular-truncated-cone-shaped wire reel is mounted in a limiting sleeve shell in a rotating fit mode; shape-fixing wires are evenly and fixedly connected to the inner wall of the elastic bag; the brushing device comprisesa collecting box and an annular brushing belt; and the supplying unit comprises a moving plate, and a paint barrel, a supplying pump and an inflation pump are mounted on the moving plate. The ceilingpaint-brushing device has the beneficial effects that the brushing unit can deform to adapt to even brushing of the plane, the near-arc-shaped edge, the arc-shaped end face and the like; and through inflation expansion of the elastic bag, each part, making contact with a ceiling, of the brushing belt can better bear force, and the paint is bonded with the ceiling more evenly and firmly.

Description

technical field [0001] The invention relates to the technical field of building construction. Background technique [0002] When painting the ceiling, conventional paint rollers cannot guarantee a low eccentricity tolerance, or if the cylinder is concave and uneven, then during the painting process, different parts of the paint receive different pressures, and it is easy to cause one end The pressure is high, while the painting pressure on other parts is very small, the paint lamination effect is poor, and the construction workers are also very laborious; if the conventional rubber column is used to adapt to the deformation, the problem of uneven pressure cannot be solved, and the rubber column itself also has errors, and When it deforms, it has a great influence on mutual extrusion, forming protrusions or depressions. The ceiling part close to the fan-shaped protrusion or cylindrical protrusion will form an arc-shaped boundary area, that is, near the arc-shaped edge, or wh...

Problems solved by technology

[0002] When painting the ceiling, conventional paint rollers cannot guarantee a low eccentricity tolerance, or if the cylinder is concave and uneven, then during the painting process, different parts of the paint receive different pressures, and it is easy to cause one end The pressure is high, while the painting pressure on other parts is very small, the paint lamination effect is poor, and the construction workers are also very laborious; if the conventional rubber column is used to adapt to the deformation, the problem of uneven pressure cannot be solved, and the rubber column itself also has errors, and When it is deformed, it will be greatly affected by mutual extrusion, forming protrusions or depressions

The ceiling part close to the fan-shaped protrusion or cylindrical protrusion will form an arc-shaped boundary area, that is, near the arc-shaped edge, or when painting the ring, fan-shaped end surface, etc., it is easy to cause brushing by using a conventional cylindrical roller. Uneven paint, for example, under the circular route, the outer area is larger than the inner area, which will easily cause less paint in the outer area; if the paint is not painted along the circular route, the route will overlap seriously, and repeated painting will easily cause excessive paint, and if there is Paint texture is not good
