Description

Double-layer staggered hair drawing brush

Technical Field

The invention relates to a double-layer staggered hair drawing brush which is suitable for a concrete surface layer with high requirement on surface roughness.

Background

The design and construction of concrete surface layer have strict requirements for main technical indexes of wear resistance, skid resistance, surface roughness, etc. of concrete slab block. In actual construction, there are two common methods for galling: firstly, the traditional napping brush is used for napping after the surface is folded, the material of the napping brush is soft, the brush body is a single layer, and the brush teeth are stressed by the gravity of the brush body to change the current situation, line type, gaps and the like of the brush teeth, so that the napping effect on the surface of concrete is poor; at present, with a hair-pulling brush adopting double-layer bristles, such as a CN 109124018A-concrete pavement hair-pulling brush and a manufacturing method thereof and a CN 201235508Y-concrete surface hair-pulling brush, although the strength of the bristles can be improved, and even and consistent textures are formed on the surface of concrete, grooves are scribed on the surface of the concrete by the hair-pulling brush teeth, so that the texture edges of the protruding part of the concrete surface are rough, and the texture surfaces are easy to sand after being extruded by the hair-pulling brush teeth, so that the appearance is poor, the surface abrasion resistance is poor, the abrasion resistance of the material of the concrete surface is seriously reduced, and the sufficient frictional resistance cannot be provided for the high-speed sliding of an airplane or the driving of a heavy-duty car; and secondly, the embossing machine is used, so that the equipment use requirement is high, more basic conditions are needed before use, heating is needed, more parts are needed, the use time is not easy to control, poor embossing or damage to a concrete surface layer is easy to cause, the operation is irreversible, and a large amount of concrete waste is generated.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a brush is drawn to double-deck staggered form for use the tradition to draw the problem that concrete texture surface grits easily, surface line edge is coarse behind the brush in the solution background art.

In order to achieve the above object, the utility model provides a following technical scheme:

a double-layer staggered hair drawing brush comprises a brush body, wherein brush teeth are arranged on the brush body, and the brush body is also connected with a handle rod; the method is characterized in that: the brush hair teeth are of an upper-lower double-layer structure consisting of upper-layer brush hair teeth and lower-layer brush hair teeth, the upper-layer brush hair teeth and the lower-layer brush hair teeth are arranged in a staggered mode, and the length of the upper-layer brush hair teeth is larger than that of the lower-layer brush hair teeth.

Furthermore, corresponding holes are punched on the end face of the brush body, and the roots of the brush hair teeth are inserted into the corresponding holes and are bonded and fixed through glue.

Furthermore, the middle parts of the brush hair teeth are clamped and fastened through two rubber plates.

Furthermore, the brush hair teeth are planted by nylon rods.
