Background
At present, the stressed main reinforcement in the actual construction of the building engineering generally adopts a straight thread sleeve connection technology. The construction method needs to perform screw thread processing on two ends of the stressed main reinforcement, and two reinforcements are connected together through a straight thread sleeve to form a whole body for force transmission. The construction method has high dependency on the technical level and quality responsibility consciousness of on-site steel bar screw thread processing personnel, large processing workload, low construction efficiency, high construction cost and more personnel requirements, but the construction industry of the building engineering has the problems of large mobility of operating personnel for a long time and uneven technical level of the operating personnel, so that the connection quality of the straight thread sleeve is unstable, the technical level of the operating personnel is low, the quality consciousness is low, the size for processing the steel bar screw head is small, the phenomenon of wire slipping is easy to occur after the connecting joint is stressed, the quality of the straight thread sleeve connection is reduced, and the integral stress of a building is influenced.
Disclosure of Invention
In order to reduce the reliance of building engineering straight thread bush connection technique to operation personnel technical merit and quality responsibility heart, reduce processing work load, promote the efficiency of construction, practice thrift construction cost, optimize relevant problems such as personnel demand quantity, the utility model provides an assembled steel bar does not have silk connecting sleeve.
An assembled steel bar threadless connecting sleeve is characterized by consisting of 8 friction fastening pieces, an inner wire fastening nut, an outer wire fastening nut and a connecting sleeve; 4 trapezoidal steel body friction fastening pieces are respectively arranged at the periphery of the first steel bar, the other 4 trapezoidal steel body friction fastening pieces are respectively arranged at the periphery of the second steel bar, and an internal thread fastening nut is arranged outside the friction fastening pieces of the first steel bar; and an inner and outer wire fastening nut is arranged outside the friction fastening piece of the second steel bar, and the connecting sleeve is connected with the inner and outer wire fastening nuts through threads and sleeved on the peripheries of the inner wire fastening nut and the inner and outer wire fastening nuts.
The outer wall of the friction fastening piece is provided with an external thread.
The internal thread fastening nut is composed of a cylindrical cavity body, a conical cylindrical cavity is arranged in the center of the cylinder, and internal thread threads are arranged on the periphery of the conical cylindrical cavity.
The internal and external screw fastening nuts are composed of cylindrical cavities, wherein external screw threads are arranged on the outer side of the cylinder, a conical cylindrical cavity is arranged at the center of the cylinder, and internal screw threads are arranged on the periphery of the conical cylindrical cavity.
The connecting sleeve consists of a cylindrical internal thread cavity body, a cylindrical non-thread cavity body and a hollow plug; cylindrical internal thread cavity body one end is connected with cylindrical cavity body one end that does not have the silk, and cylindrical cavity body other end that does not have the silk is connected with hollow end cap one end.
The utility model discloses easy and simple to handle, the matched stack is nimble, need not the job site and carry out reinforcing bar screw thread processing, requires very low to construction operation personnel technical level to reduce the reliance of building engineering straight thread muffjoint technique to operation personnel technical level and quality responsibility heart, reduce work load, promote the efficiency of construction, practice thrift construction cost, optimize personnel demand quantity etc. relevant problem, be favorable to building engineering construction quality's promotion and healthy steady development.
