False-screwing-prevention bolt-sphere joint with visual bolt screwing-in process and construction method of false-screwing-prevention bolt-sphere joint
The invention provides an anti-false-screwing bolt-sphere joint with a visual bolt screwing-in process and a construction method thereof, and belongs to the field of steel structure space structures. The problem of false screwing of an existing bolt-sphere joint due to the fact that constructors cannot directly observe the screwing process of a bolt is solved. The threaded end of a high-strength bolt of the spherical joint is screwed into a bolt ball, the straight rod end of the high-strength bolt is connected with a conical head, the conical head is installed at the end of a rod piece, the periphery of the high-strength bolt is sleeved with a sleeve, reset springs are arranged on the two sides of an indication block, the indication block is connected with the outer wall of the sleeve through the reset springs, and the reset springs are always in a stretching state; and the other end is connected with the sleeve outer wall. The groove in the inner wall of the sleeve makes contact with the protrusions arranged on the high-strength bolt to transmit torsion, compared with a traditional bolt-sphere joint in which the high-strength bolt is driven to be screwed in through a pin, the joint is more uniform in stress and can transmit larger torque, and meanwhile the situation that the screwing-in depth of the bolt is misjudged due to the fact that the pin is twisted off can be avoided.
本发明提出了一种螺栓拧入进程可视化的防假拧螺栓球节点及其施工方法，属于钢结构空间结构领域。解决了现有的螺栓球节点由于施工人员无法直接观察螺栓拧入进程而导致的“假拧”现象的问题。该球形节点的高强螺栓的螺纹端拧入螺栓球内，直杆端与锥头连接，锥头安装在杆件的端头，高强螺栓外周套固有套筒，指示块两侧设置有复位弹簧，并通过复位弹簧与套筒外壁连接，复位弹簧始终处于拉伸状态，一端与指示块的连接板相连，另一端与套筒外壁相连。本发明通过套筒内壁凹槽和高强螺栓上所设凸起接触传递扭力，相较于传统销钉带动高强螺栓拧入的螺栓球节点，本节点受力更均匀，可传递更大的扭矩，同时可以避免由于销钉拧断导致的螺栓拧入深度误判。
