Abstract
The utility model provides a sleeve for connecting high-strength hot-rolled ribbed steel bars, which comprises a connecting sleeve with inner threads and is characterized in that the connecting sleeve adopts a high-strength sleeve using the same materials with the high-strength hot-rolled ribbed steel bars, and joint positions of pairwise connected high-strength hot-rolled ribbed steel bars have higher strength and better ductility and plasticity, thereby ensuring stable performance of the joint positions. Simultaneously, the sleeve has the advantages of fast connection speed, wide application range, strong adaptability, remarkable economic and social benefits and the like.
Description
Technical field
The utility model relates to a kind of reinforcing bar connection sleeve, and especially a kind of high strength HRB500 hot rolled ribbed steel bar connects uses sleeve, belongs to constructional materials accessory technical field.
Background technology
High-intensity HRB500 hot rolled ribbed steel bar is the constructional materials of a kind of economy type, heavy duty detergent, owing to have higher intensity and toughness and plasticity preferably, therefore, in the reinforcing bar use, its use amount reduces 10%～30% than the ordinary hot rolled rib steel bar, implement conservation-minded society and a kind of constructional materials of keypoint recommendation thereby become country, also have simultaneously anti-seismic performance good, be convenient to advantage such as construction.
In the use of high-intensity HRB500 hot rolled ribbed steel bar, often two above reinforcing bars to be coupled together use, the connection of prior art is: band externally threaded reinforcing bar in twos in end is screwed in the tapped ordinary steel sleeve, thereby finish connection between reinforcing bar.So in use, can be low, toughness and plasticity difference etc. are former thereby quality problems occur in the junction because of the intensity of ordinary steel sleeve self, even bury potential safety hazard.In addition, because high-intensity HRB500 hot rolled ribbed steel bar is in research and development at home and applies the stage, in architectural design and construction, use less, even in building trade, still there are not relevant standard, rules and a standard, therefore, influenced applying of high-intensity HRB500 hot rolled ribbed steel bar.Therefore, must be improved, to satisfy the demand of market to high-intensity HRB500 hot rolled ribbed steel bar to prior art.
Summary of the invention
The purpose of this utility model is to provide a kind of high-strength hot rolled ribbed steel bar to connect and uses sleeve, improves the quality of reinforcing bar junction in twos by this sleeve, promotes applying of described reinforcing bar, satisfies the demand of market to described reinforcing bar.
The utility model is finished by following technical proposal: a kind of high-strength hot rolled ribbed steel bar connects uses sleeve, comprise tapped branch sleeve on it, it is characterized in that described branch sleeve adopts the high strength sleeve with the identical material of high-strength hot rolled ribbed steel bar.
Described branch sleeve adopts the microalloying 20MnSi hot rolled circular steel identical with the HRB500 hot rolled ribbed steel bar.
The internal thread of described branch sleeve adapts with the external screw thread of the high-strength hot rolled ribbed steel bar that is connected, so that closely connect.
The length of described branch sleeve is 35～100mm, and external diameter is 20～70mm, and concrete length is determined with the specification that external diameter is looked the high-strength hot rolled ribbed steel bar that will be connected.
Described branch sleeve internal thread pitch is 2.0～3.5mm, and the screw thread nominal diameter is 16.5～41.0mm, specifically looks the specification of the high-strength hot rolled ribbed steel bar that will connect and determines.
The utility model compared with prior art has following advantage and effect: adopt such scheme, can make in twos the high-strength hot rolled ribbed steel bar that connects have higher intensity and toughness and plasticity preferably in its junction, guarantee the junction stable performance, have advantages such as connection speed is fast, applied range, applicability is strong, economic and social benefit is remarkable simultaneously.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
The high-strength hot rolled ribbed steel bar that the utility model provides connects uses sleeve, the branch sleeve 2 that comprises band internal thread 1 on it, this branch sleeve 2 adopts the high strength sleeve with the identical material of high-strength hot rolled ribbed steel bar, it specifically is the sleeve of using the microalloying 20MnSi hot rolled circular steel identical to be processed into the HRB500 hot rolled ribbed steel bar, its external diameter is 26mm, length is 40mm, and inner thread parameter is M17 * 2.5-6H.
During connection, the termination (being with external screw thread on the termination) of reinforcing bar to be connected is in twos screwed in the branch sleeve, screw in the position and respectively be half of length sleeve, with pipe wrench or torque spanner adjustment sleeve position and tighten, can use.
