Description
Technical Field
the utility model belongs to the building trade field, concretely relates to hole device is visited in connection with steel bar quality acceptance.
Background
The steel bar is a steel bar and is a kind of building material. With the continuous development of the building industry, the steel structure is widely applied to the fields of large-scale stadium buildings, super high-rise buildings and the like. At present, the steel bar connection technology is mature day by day, and the connection modes of the steel bars mainly comprise four types, namely binding and overlapping, mechanical connection, sleeve grouting connection and welding. However, the connection strength of the steel bars is difficult to guarantee for the lap joint of the stand steel bars, the lap joint mode is that two steel bars are in parallel lap joint, and the verticality cannot be guaranteed.
The binding and lapping are mainly suitable for the connection of small-sized steel bars. The welding connection can be divided into flash butt welding, gas pressure welding, vertical steel electroslag pressure welding, horizontal steel narrow gap welding and the like. Mechanical connections can be divided into cold-pressed sleeves, tapered threads, stripped and rolled straight threads, upset and turned straight threads, and the like.
The ligature overlap joint is only simple with two reinforcing bar overlap joints ligature together, can cause at great eccentric force, is unfavorable for the structure atress, influences the interval of reinforcing bar. And the connecting device is only used for connecting non-main stressed steel bars with smaller diameters, and cannot meet the requirements of most cases.
The welding connection is that the joints of two steel bars are welded into a whole by an electric welding machine. Welding connection is also easy to have eccentricity, welding quality, current and the technology of an operator have great influence, and poor welding quality and brittle fracture can be caused if the joint is not polished in place or is secondarily polluted. The carbon, manganese and silicon contents of the III-grade steel bar are high, the welding quality is influenced, and particularly when electroslag pressure welding is selected, the joint inspection qualified rate is generally low. The welding connection needs special work, the current is large, safety accidents are easy to happen, and the requirements on weather and sites are severe. The construction efficiency is lower, and the stress performance after connection is not as good as that of mechanical connection.
The most widely applied on site in mechanical connection is a connection mode that a threaded screw head processed by a reinforcing steel bar end is meshed with a threaded connection sleeve to form a whole, and the mechanical connection is suitable for all concrete structural engineering with earthquake proofing and non-earthquake proofing. The deformed steel bar has high precision, good tooth shape and smooth tooth surface; the connection quality is stable; the joint has no damage through 200 ten thousand fatigue tests of the international civil engineering association and has excellent fatigue resistance; the low-temperature resistance is outstanding, and the joint can still be connected with the wood with the same strength under the low-temperature test of minus 40 ℃; the application range is basically not limited, the device is suitable for connecting the reinforcing steel bars at any position and direction, and can also be used in occasions where the bent reinforcing steel bars, the fixed reinforcing steel bars and the reinforcing cage cannot rotate; the method is suitable for environmental protection requirements: the construction is free of open fire, is safe and reliable especially under the construction conditions of flammability, explosiveness, high altitude and the like, and can be constructed in all weather; the construction period can be shortened, the engineering quality can be improved, and the energy consumption can be reduced.
Although the existing mechanical connecting sleeve has great advantages, the existing mechanical connecting sleeve has a plurality of problems in actual construction on site. At present, the problem that straight thread muffjoint technique exists: the inner structure is invisible after connection, whether effective connection is realized between two reinforcing bars can not be detected, and the connection quality of the two reinforcing bars can not be guaranteed. If the middle part of the sleeve is hollow: even in many times, the worker makes the great strength difficult to screw up by rotation again, and this just causes two reinforcing bar ends and does not draw close, appears that the sleeve middle part is hollow, and mechanical interlock length is not enough, and then influences atress and connection quality, reduces atress performance and security performance. In addition, the construction is labor-consuming, resulting in low construction efficiency.
