Abstract
A treatment method for a concrete surface steel bar is characterized in that a hollow drill is used for drilling concrete around a steel bar head, the drilling depth ranges from 2 cm to 6 cm, then the steel bar is cut off, the cut-off part is lower than the surface of the concrete, and then a hole is filled with concrete to be flat. A steel bar cutting off device capable of penetrating into concrete comprises a power part and a cutting off device body, and the cutting off device body is composed of a jaw arm, a feeding sleeve, a spring, a conical sleeve, a clamping jaw, a bolt, blades and screws. The jaw arm is connected with the feeding sleeve through a thread, the spring is installed between the feeding sleeve and the conical sleeve, the conical sleeve is installed between the feeding sleeve and the clamping jaw, the clamping jaw is fixedly connected with the jaw arm through the bolt, the blades are fixed to the clamping jaw through the screws, the jaw arm is connected with the power part, and an electric impact drill serves as the power part. According to the treatment method for the concrete surface steel bar and the steel bar cutting off device, the steel bar prone to rusting is sealed in the concrete, and a manufactured special tool is simple in structure, convenient to use and capable of cutting off the steel bar in the concrete hole. The surface of the concrete is smooth, tidy, attractive and free of the influences of iron molds.
Description
Technical field
The present invention relates to the process of concrete surperficial reinforcing bar.
Background technology
In large-sized concrete casting process, its surface leaves many reinforcing bars unavoidably, as formwork tie etc., affect the outward appearance of concrete surface, more seriously it gets rusty under the erosion of rainwater, of long duration cause the concrete surface built up to form much rain after to become rusty water droplet trace, have impact on outward appearance and the intensity of building.
Summary of the invention
The object of the present invention is to provide a kind of processing method and instrument thereof of concrete surface reinforcing bar, make concrete surface not occur iron mold, keep attractive in appearance.
The technical solution adopted in the present invention is a kind of processing method of concrete surface reinforcing bar, its main points are first to be punched by the concrete around steel bar end with core drill, and the degree of depth is 2-6cm, then is blocked by reinforcing bar, hole lower than concrete surface, then is filled and led up with concrete by truncated position.
Can only to shear for the reinforcing bar of concrete surface at present or sawed-off, truncated position is concordant with concrete surface as much as possible, want to polish is all that part is very in thing that is consuming time, effort, letting alone will lower than concrete, so people just keep the attractive in appearance of concrete surface by antirust treatment, and steel bar end of leaving stays concrete surface.The present invention fundamentally solves the impact of exposed reinforcing bar on concrete surface, first punches at its periphery, cropper can be entered, by truncated position lower than concrete surface, then is filled and led up in hole with concrete, and thoroughly isolated reinforcing bar and extraneous contact, ensure its non-corrosive.
First punched by the concrete around steel bar end with φ 60 core drill, the degree of depth is 2-3cm.
Reinforcing bar truncated position is lower than concrete surface 1-2cm.
For this reason specially make special tool
One can go deep into concrete bar cutter, it comprises power and cropper, cropper by: pawl arm, feeding cover, spring, tapered sleeve, jaw, bolt, blade and screw form, pawl arm and feeding cover are threaded connection, and spring fitting is between feeding cover and tapered sleeve, and tapered sleeve is installed on and between feeding cover and jaw, jaw is fixedly connected with pawl arm by bolt, blade is fixed on jaw by screw, and pawl arm is connected with power, and power is electric impact drill.
Its operating principle loads electric impact drill (Electric portable drill) for rotating three-jaw cropper pawl arm, and by rotary claw arm, feeding is overlapped mobile, utilize spring compression tapered sleeve to transmit cut-out power, on three-jaw, alloy blade does radial rotary feed cutting, until cut off steel bar end.
Utilize the core drill of φ 60 first by dark for the concrete drill around steel bar end 2 to 3 centimeters, then rotation three-jaw cutter is contained on electric impact drill stretches into steel bar end 1-2 centimetre, utilize alloy blade sword on three-jaw to do radial rotary feed cutting, until cut off steel bar end.
The present invention breaks traditions confinement, looks for another way, starts with from the most basic part, be enclosed in concrete by the reinforcing bar easily become rusty, and the special tool structure made thus is simple, easy to use, can cut off reinforcing bar in concrete hole.Make concrete surface neatly smooth, attractive in appearancely not affect by iron mold.
Accompanying drawing explanation
Fig. 1 is the structural representation of cropper
Wherein: 3 spring 4 tapered sleeve 5 jaw 6 bolt 7 blade 8 screws are overlapped in 1 pawl arm 2 feeding.
Detailed description of the invention
Conduct further description below in conjunction with accompanying drawing 1 pair of patent of the present invention
A processing method for concrete surface reinforcing bar, first punched by the concrete around steel bar end with φ 60 core drill, the degree of depth is 2-6cm, and the general degree of depth is 2-3cm, then is blocked by reinforcing bar, and hole lower than concrete surface, then is filled and led up with concrete by truncated position.Reinforcing bar truncated position is lower than concrete surface 0.5-5cm.For reducing the workload of boring and the impact on concrete strength, reinforcing bar truncated position is lower than concrete surface 1-2cm.
Specially for achieving the above object make special tool
One can go deep into concrete bar cutter, it comprises power and cropper, cropper overlaps 2 by: pawl arm 1, feeding, spring 3, tapered sleeve 4, jaw 5, bolt 6, blade 7 and screw 8 form, pawl arm 1 and feeding are overlapped 2 and are threaded connection, and spring 3 is installed on and feeding is overlapped between 2 and tapered sleeve 4, and tapered sleeve 4 is installed on and feeding is overlapped between 2 and jaw 5, jaw 5 is connected with pawl arm 1 by bolt 6, blade 7 is fixed on jaw 5 by screw 8, and pawl arm 1 is connected with power, and power is electric impact drill.
Its operating principle is that the pawl arm rotating three-jaw cropper loads Electric portable drill, and by rotary claw arm, feeding is overlapped mobile, utilize spring compression tapered sleeve to transmit cut-out power, on three-jaw, alloy blade does radial rotary feed cutting, until cut off steel bar end.
