Description
Technical Field
The utility model relates to a plastering arc scraper knife which is applied to the field of building construction tools.
Background
In the building construction specification, arc treatment (arc wiping) is required to be carried out on internal corners and pipe roots. In the existing actual construction, a special tool is not used for arc wiping, and several sets of tools are often used for switching and matching operation. The plugging queen bee is used more when arc is smeared at the internal corner or the pipe root, and a small stirring barrel is adopted for stirring during field construction because the plugging queen bee is used in a small amount and the hardening time is short. The arc-cleaning tool (such as an arc-cleaning knife) which is commonly adopted in the market at present is limited by the angle of a handle, and the stirring barrel is small, so that the operation is inconvenient, and therefore, the putty knife is mostly adopted for sanitary cleaning of the constructed stirring barrel. The existing process and use tools for performing arc treatment on internal corners and tube roots are as follows: firstly, shoveling materials and stirring in a stirring barrel by using a putty knife, shoveling materials to a construction area by using the putty knife and paving the materials, then performing calendaring and plastering by using an arc plastering knife, and cleaning the stirring barrel by using a steel wire brush and the putty knife after construction is finished. The method has the defects of more tools, complicated working procedures, complex operation and the like. Therefore, it is desirable to provide a scraper knife which integrates the functions of scraping, stirring, arc scraping, scraping and stirring tank cleaning, simplifies the arc scraping process, and is convenient to operate.

The plane of the arc formed by the transverse front end edge of the arc-wiping plate forms an included angle of 44-46 degrees with the extending direction of the arc-wiping plate. The optimized parameters of the plate tongue ensure that the shoveling and stirring effects are optimal.
The connecting rod includes head rod and second connecting rod, the head rod sets up in the horizontal rear end top of smearing the arc board and perpendicular mutually with smearing the arc board extending direction along vertical direction, the second connecting rod extends and sets up in smearing the horizontal rear side top of arc board along parallel smearing the arc board extending direction, the lower extreme of this head rod and smear the end limit along central authorities fixed connection behind the arc board, the head rod upper end is connected with the front end of second connecting rod, the rear end of second connecting rod is connected with the front end handle, the handle from with second connecting rod junction play to horizontal rear side top slope extend and be 134 with the second connecting rod and be 136 contained angles.
The preferred connected mode and the angle of head rod, second connecting rod, handle for wipe arc board convenient operation and laborsaving, wipe arc angle and effect are good.
The connecting rod is a solid round pipe with the radius of 7-9 mm.
The preferred connecting rod is lightweight and strong.
The arc-wiping plate is a metal arc-wiping plate, and the connecting rod is a metal connecting rod.
The arc wiping plate and the connecting rod made of the preferable materials are firm and durable.
Compared with the prior art, the method has the following advantages:
1) according to the arc-wiping shovel knife, the arc-wiping plate with the front end opening and the rear end being closed and in the shape of the arc is designed, and the plate tongue connected to the outer edge of the front end of the arc-wiping plate is matched, so that the arc-wiping shovel knife integrates the functions of shoveling, stirring, arc wiping, shoveling, cleaning a stirring barrel and the like, the arc-wiping process is greatly simplified, and the operation is convenient;
2) the optimized arc shape at the rear end of the arc-wiping plate ensures the high capacity of the shoveling material of the arc-wiping plate while the arc-wiping effect is the best;
3) the optimized parameters of the plate tongues ensure that the material shoveling and stirring effects are optimal;
4) the preferred connected mode and the angle of head rod, second connecting rod, handle for wipe arc board convenient operation and laborsaving, wipe arc angle and effect are good.
