Abstract
A kind of processing method of concrete surface reinforcing bar, it, which is characterized by, is first punched the concrete around steel bar end with core drill, and depth is 26 cm, then reinforcing bar is blocked, and truncated position is less than concrete surface, then is filled and led up hole with concrete.A kind of bar cropper for going deep into concrete, it include power and cropper, cropper by：Pawl arm, feeding set, spring, tapered sleeve, clamping jaw, bolt, blade and screw composition, pawl arm is connected through a screw thread with feeding set, spring is installed on and fed between set and tapered sleeve, tapered sleeve is installed on and fed between set and clamping jaw, clamping jaw is fixedly connected by bolt with pawl arm, blade is fixed on clamping jaw by screw, and pawl arm is connected with power, and power is electric impact drill.The reinforcing bar easily become rusty is enclosed in concrete by the present invention, and the specific purpose tool thus made is simple in construction, easy to use, and reinforcing bar can be cut off in concrete hole.Make concrete surface smooth neat, it is attractive in appearance not influenceed by iron mold.
Description
Technical field
The present invention relates to the processing of the surface reinforcing bar of concrete.
Background technology
Its surface leaves many reinforcing bars, such as form tie unavoidably in large-sized concrete casting process, influences concrete
The outward appearance on surface, more seriously it got rusty under the erosion of rainwater, cause the concrete surface built up to be formed over time
Become rusty water droplet trace after many rain, have impact on the outward appearance and intensity of building.
The content of the invention
It is an object of the invention to provide a kind of processing method of concrete surface reinforcing bar and its instrument, make concrete surface
Iron mold is occurred without, is kept attractive in appearance.
The technical solution adopted in the present invention is a kind of processing method of concrete surface reinforcing bar, and it, which is characterized by, first uses
Core drill punches the concrete around steel bar end, and depth is 2-6 cm, then reinforcing bar is blocked, and truncated position is less than concrete table
Face, then filled and led up hole with concrete.
It can only be sheared or sawed-off for the reinforcing bar of concrete surface at present, truncated position is flat with concrete surface as far as possible
Together, want to polish all be part extremely in the thing of time-consuming, effort, to be let alone less than concrete, so people are simply by anti-
Rust handles to keep the attractive in appearance of concrete surface, and steel bar end of leaving stays in concrete surface.The present invention fundamentally solves naked
Influence of the reinforcing bar of dew to concrete surface, first in the punching of its periphery, cropper can be entered, truncated position is less than into concrete table
Face, then filled and led up hole with concrete, thoroughly isolation reinforcing bar and extraneous contact, it is ensured that its non-corrosive.
First the concrete around steel bar end is punched with the core drills of φ 60, depth is 2-3cm.
Reinforcing bar truncated position is less than concrete surface 1-2cm.
Special make specific purpose tool for this
A kind of bar cropper for going deep into concrete, it include power and cropper, cropper by：Pawl arm, feeding set,
Spring, tapered sleeve, clamping jaw, bolt, blade and screw composition, pawl arm are connected through a screw thread with feeding set, and spring is installed on and fed
Between set and tapered sleeve, tapered sleeve is installed on and fed between set and clamping jaw, and clamping jaw is fixedly connected by bolt with pawl arm, and blade passes through
Screw is fixed on clamping jaw, and pawl arm is connected with power, and power is electric impact drill.
Its operation principle loads electric impact drill for rotation three-jaw cropper pawl arm（Electric hand drill）, feeding is made by rotary claw arm
Set movement, alloy blade on cut-out power, three-jaw is transmitted using spring compression tapered sleeve and does radial rotary feed cutting, until cut-out
Steel bar end.
It is first that the concrete drill around steel bar end is deep 2 to 3 centimeters using φ 60 core drill, then three-jaw cutter will be rotated
1-2 centimeters of steel bar end is stretched on electric impact drill, radial rotary feed cutting is done using alloy blade sword on three-jaw, until cutting
Disconnected steel bar end.
The present invention breaks traditions confinement, looks for another way, and starts with from most basic part, the reinforcing bar easily become rusty is enclosed in into concrete
In, the specific purpose tool thus made is simple in construction, easy to use, and reinforcing bar can be cut off in concrete hole.Make concrete surface light
It is sliding neat, it is attractive in appearance not influenceed by iron mold.
Brief description of the drawings
Fig. 1 is the structural representation of cropper
Wherein：The screw of 1 pawl arm 2 feeding set 3 spring, 4 tapered sleeve, 5 clamping jaw, 6 bolt, 7 blade 8.
Embodiment
It is further described below in conjunction with 1 pair of patent of the present invention of accompanying drawing
A kind of processing method of concrete surface reinforcing bar, is first punched the concrete around steel bar end with the core drills of φ 60,
Depth is 2-6 cm, and general depth is 2-3cm, then reinforcing bar is blocked, and truncated position is less than concrete surface, then with concrete by hole
Fill and lead up.Reinforcing bar truncated position is less than concrete surface 0.5-5cm.Workload for reduction drilling and the influence to concrete strength,
Reinforcing bar truncated position is less than concrete surface 1-2cm.
It is special to achieve the above object to make specific purpose tool
A kind of bar cropper for going deep into concrete, it include power and cropper, cropper by：Pawl arm 1, feeding set
2nd, spring 3, tapered sleeve 4, clamping jaw 5, bolt 6, blade 7 and screw 8 are constituted, and pawl arm 1 is connected through a screw thread with feeding set 2, and spring 3 is pacified
Loaded between feeding set 2 and tapered sleeve 4, tapered sleeve 4 is installed on and fed between set 2 and clamping jaw 5, and clamping jaw 5 passes through bolt 6 and pawl arm
1 connection, blade 7 is fixed on clamping jaw 5 by screw 8, and pawl arm 1 is connected with power, and power is electric impact drill.
Its operation principle loads electric hand drill for the pawl arm of rotation three-jaw cropper, makes feeding set movement by rotary claw arm,
Alloy blade on cut-out power, three-jaw is transmitted using spring compression tapered sleeve and does radial rotary feed cutting, until cut-out steel bar end.
