Description

Concrete road surface construction napping device

Technical Field

The invention relates to the technical field of road engineering, in particular to a roughening device for concrete pavement construction.

Background

In the road surface of highway, city road and airport, China adopts the most widely common concrete road surface poured on site, and the concrete road surface is not provided with reinforcing steel bars except for joint areas and local areas (edges or corners), also called plain concrete road surface, and is a road surface structure poured on site by using plain concrete or only a small amount of reinforcing steel bars at the edges and corners of the road surface plate, so the construction is convenient and the cost is low.

In the concrete road construction process, after concrete is poured, when the concrete is slightly pressed by hands and does not stick to hands, the surface of the concrete needs to be napped so that the concrete plate surface has certain texture washing degree and roughness, and therefore the concrete road can provide stable friction force when driving and is convenient for drainage of the concrete surface.

At present, when a concrete road surface is napped, a napping brush is mainly adopted, and napping is realized by manually pulling the napping brush to move on the concrete surface, although the concrete surface can be napped effectively, in the actual construction process, in order to ensure labor saving of the napping brush in the napping process and smoothness of textures, as shown in the attached drawing 1, an included angle between the napping brush and the pull rod is an obtuse angle, so that pulling along the inclined direction of the napping brush can be more labor saving when the concrete surface is pulled, the textures are smoother, but the napping brush with the structure can only be napped in one direction, after single napping is completed, the napping brush needs to be lifted manually and sent to the other side of the concrete road surface, then the napping brush is put to be attached to the concrete road surface for napping, the napping brush needs to be lifted frequently, the manual burden is large, and the napping efficiency is low.

On the basis of the hairbrush, a novel hairbrush structure as shown in the attached figure 2 is designed, and the hairbrush passes through two designed surfaces, when the hair is pulled and napped, the hair brush with the included angle of the hair brush and the pull rod being an obtuse angle is utilized for napping, after the hair is napped in a single direction, the brush with an acute included angle is attached to the surface of the concrete, and the brush can be pushed to move to continue to be brushed, thereby avoiding the problem that the napping brush is frequently lifted and returned, effectively improving the napping efficiency, but in the actual use process of the napping brush with the structure, but also has the problem that after one-way napping is finished, the napping brushes can be continuously napped only by continuously turning and switching the napping brushes on the two sides, the concrete pavement construction napping device also has the problem that the worker is required to frequently lift and turn over the pavement, so that the labor burden of the worker is large.
