Description

Color code spraying device for grounding flat steel and construction method Technical Field The invention relates to the technical field of auxiliary tools for spraying construction, in particular to a color code spraying device and a construction method for grounding flat steel. Background In construction engineering, an electric strong and weak electricity vertical shaft, a power distribution room and a power transformation and distribution room are dense areas laid by a grounding trunk line, and the grounding function is mainly to guide the harmful current generated by an electric fault, static charge and current generated when a building is struck by lightning into the ground, so that the personnel is prevented from being struck by electric shock, equipment and circuits are prevented from being damaged, fire is prevented, electrostatic damage is prevented, the normal operation of an electric power system is guaranteed, and meanwhile, the electric safety measure is also used for guaranteeing the normal operation and personal safety of electrical equipment. The grounding trunk is connected with the grounding device, and leakage current, static charge, lightning current and the like possibly generated on electrical equipment and other production equipment are led into the ground, so that personal electric shock and accidents such as fire and explosion possibly occurring are avoided. According to the 23.2.6 th rule of GB50303-2015 "quality of construction acceptance Specification of building electric engineering", the whole length or interval section of the grounding trunk line and the surface near each connecting part should be coated with yellow and green alternate stripe marks with the same width of 15 mm-100 mm. The traditional spraying construction method comprises the steps of measuring the length of a grounding trunk line required before construction, measuring the width of yellow-green stripes on the flat iron by using a measuring scale, drawing stripe boundaries by using a marking pen, respectively spraying yellow-green alternate stripe paint in the stripe boundaries, and mounting the flat iron after the paint is dried. The traditional method has the following defects that 1, the flat steel yellow-green stripes adopt manual measuring rules, the error is large, the interval and the inclination of the yellow-green stripes are inconsistent and are not standard, and the appearance is poor. 2. The flat steel yellow-green stripes are manually marked by adopting a manual measuring ruler, and the side lines for defining the intervals of the yellow-green stripes are manually drawn, so that the work is relatively high in repeatability, relatively long in duration and low in efficiency, and the labor and the materials are wasted. In the existing spraying device for grounding flat steel, as disclosed in patent application number 202022480759.8, the device mainly solves the problem that the pungent smell of the paint damages the respiratory tract of workers, the paint is carelessly sprayed to the skin of the workers and is also corroded, and the spraying work of one color can only be realized for the grounding wire, and the 45-degree stripe spraying cannot be realized. The utility model patent with the application number 202222149987.6 discloses a ground flat steel twill paint brush, which can paint twill on ground flat steel, but has the following problems that 1, only a single ground wire can be painted each time, the working efficiency is low, 2, flat steel clamping grooves are of fixed size, the thicknesses of different types of ground flat steel are inconsistent, when the ground flat steel with the unmatched size of the flat steel clamping grooves is placed in the flat steel clamping grooves, gaps are reserved between the ground flat steel and front and rear twill grooves, when paint is painted or sprayed, if the amount of paint is not well painted or sprayed is controlled, paint easily flows into the gaps to form sagging stripes in the areas where the paint is not needed, so that the marking stripes are not standard, the appearance is poor, if the ground flat steel with the matched size is placed in the flat steel clamping grooves, the ground flat steel is placed in and taken out, the ground flat steel is easy to scratch, when the ground flat steel is taken out, the paint is not dried, and the paint is easy to scratch the two sides of the flat steel clamping grooves, and the marking stripes are easily rubbed. Disclosure of Invention The invention aims to solve the technical problem of overcoming the defects of the prior art and providing a color code spraying device and a construction method for grounding flat steel. The invention is realized by the following technical scheme: a color code spraying device of ground flat steel, comprising: two frame guide rails (1) which are arranged on the ground in parallel; The two sides of the frame (2) are arranged on the two frame guide rails (1) in a rolling way thr
