Description
Technical field
The utility model relates to construction technical field of tools.
Background technology
Reinforced steel bar straight thread coupling sleeve has another name called splice, is in order to connecting reinforcement and has with the connector of a silk corresponding screw thread, is applicable to bear draw, press the bar connecting in all kinds of structures reinforced concrete structures of bi-directional force to construct.Its construction process is: end reinforced technique for rolling is processed into straight thread, and is interconnected by two reinforcing bars with corresponding branch sleeve.Compared to traditional welding procedure, have the following advantages: energy-conservation, material-saving; Can comprehensively connect; System can be given in advance, not take the duration, all-weather construction; Easy to operate, quick, speed of application is fast.Splice connects has become the most general splice connected mode.
Reinforced bar straight thread joint, is best suited for the reinforcing bar of more than diameter 14mm, and the reinforcing bar of more than 14mm is the muscle of being advocated of major structure of construction usually, and the quality of its straight thread connector quality, often decides serviceability and the security performance of engineering.Therefore have extremely strict requirement for straight thread connector installation quality, such as, mutually held out against by two steel bar heads during construction in sleeve centre position, its joint screw-down torque should comply with the following requirements.
Use torque spanner is measured, and precision is ± 5%.
| Bar diameter (mm) | 16～18 | 20～22 | 25 | 28 | 32 | 36～40 |
| Screw-down torque (N*m) | 100 | 200 | 250 | 280 | 320 | 350 |
But straight thread connector is all that artificial spanner is installed at present, during installation, joint screw-down torque mainly relies on the construction experience of workman, and installation quality is often uneven, and the poor frequent needs of outgoing quality are done over again, delay the duration, if sampling observation is not attended the meeting bring great hidden danger to the quality of engineering.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of installation reinforced steel bar straight thread coupling sleeve spanner, can reduce reinforced steel bar straight thread coupling sleeve mounting torque disqualification rate, accelerating construction progress, ensure construction quality.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of installation reinforced steel bar straight thread coupling sleeve spanner, comprise the spanner spanner and pinch bar that are fixedly connected with, described handle comprises tubular handle and boosting-rod, one end of described tubular handle is closed and is fixedly connected with described spanner, other end opening; Described boosting-rod and described tubular handle match, and described boosting-rod embeds from tubular handle opening part and is socketed with tubular handle, and can be free to slide; Described boosting-rod is provided with scale.
Further, described tubular handle and boosting-rod are chrome alum steel alloy material.
Further, described boosting-rod comprises the handling section of chi section and end, and described chi section is provided with scale, and described handling section surface is provided with Z-Correct bump mapping Z-correct.
Further, the external diameter of described handling section equals the external diameter of tubular handle.
The beneficial effect adopting technique scheme to produce is: the utility model structure is simple, easy to make, sturdy and durable; The handle of the utility model to assembly wrench improves, and becomes the handle of extension type, when carrying out reinforced bar straight thread sleeve and installing, is pulled out by boosting-rod, increases the moment length of spanner; When doing other uses, pushed by boosting-rod in tubular handle, handle is short, uses more convenient.
Use the utility model can make the length that the mounting torque criterion and quantity of workman to reinforced steel bar straight thread coupling sleeve is spanner, operation is easily implemented, and qualification rate is high, reinforced steel bar straight thread coupling sleeve mounting torque disqualification rate can be reduced, minimizing is done over again, and saves human and material resources, reduces construction cost; The installation effectiveness of sleeve can be promoted, accelerating construction progress, ensure construction quality.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Wherein, 1, spanner; 2, tubular handle; 3, boosting-rod; 4, scale.
Detailed description of the invention
The utility model discloses a kind of installation reinforced steel bar straight thread coupling sleeve spanner, comprise the spanner spanner 1 and pinch bar that are fixedly connected with, described handle comprises tubular handle 2 and boosting-rod 3, and one end of described tubular handle 2 is closed and is fixedly connected with described spanner 1, other end opening; Described boosting-rod 3 matches with described tubular handle 2, and described boosting-rod 3 embeds from tubular handle 2 opening part and is socketed with tubular handle 2, and can be free to slide; Described boosting-rod 3 is provided with scale 4.Described tubular handle 2 and boosting-rod 3 are chrome alum steel alloy material.
The utility model adopts sleeve structure, and structure is simple, easy to use, adopts the manufacture of chrome alum steel alloy, sturdy and durable.
Described boosting-rod 3 comprises the handling section of chi section and end, and described chi section is provided with scale 4, and described handling section surface is provided with Z-Correct bump mapping Z-correct.Scale 4 separates with Handheld Division, reduces the damage of wearing and tearing to scale 4, the service life of extension scale 4.Z-Correct bump mapping Z-correct adds the steadiness that people holds, and sweat is easily discharged, and hand not easily skids.
The external diameter of described handling section equals the external diameter of tubular handle 2.Boosting-rod 3 can not be dropped in tubular handle 2, fetch conveniently.
Boosting-rod 3 arranges scale 4 chi, can according to workman's Different age group, the features such as different physique, before carrying out the operation of reinforced bar straight thread connection construction, the workman of torque spanner to each field operation is utilized to test, when workman normally has an effect, reach how when numerical value in the length of moment, the moment of torsion produced can meet the torque demand that reinforced bar straight thread sleeve is installed, allow workman when installation straight screw sleeve, clear and definite understanding is had to the moment size needed for straight thread connector, quantize to the extension elongation of boosting-rod 3, reduce enforcement difficulty, the quality that reinforced bar straight thread is connected better is ensured.
By use of the present utility model, ensure that the installation quality of reinforced bar straight thread joint, greatly reduce doing over again of straight thread connector installation, 30% is improved than common wrench efficiency of construction, save a large amount of human and material resources, steel corrosion quantity once passes through, and avoiding affects the duration, creates great economic benefit.
