The self-locking bolt assembly of the steel structure anti-pulling piece has the working principle that:
before the anti-pulling member 3 is installed, as the connecting concave plate 81 and the connecting convex plate 82 are in a sliding connection mode, a worker can quickly determine the total length of the connecting concave plate 81 and the connecting convex plate 82 according to the length of the cross beam 1, and install the anti-pulling member 3 at two ends of the cross beam 1, through the arrangement of the limiting grooves 31 and the buckling grooves 11, the worker can easily and quickly install the anti-pulling member 3 at the connection positions of the two side longitudinal beams 2 and the bottom cross beam 1 accurately, and limit the anti-pulling member 3 by clamping the buckling seat 4 in the buckling grooves 11, so that the tensile and compressive capacities of the whole anti-pulling member are further improved, the possibility that the anti-pulling member is loose or separated from the cross beam under the action of strong shock or larger wind force is further improved, and the good fixing effect of the anti-pulling member in the use of the steel structure building is further improved;
when the anti-pulling member 3 is installed, after the anti-pulling member 3 is placed at the joint of the side stringers 2 and the bottom cross beam 1 of the whole anti-pulling assembly 7, a worker uses a cross screwdriver to screw the screw 5 into a foundation for a certain distance, then uses a hexagonal wrench to enable the locking nut 62 to be installed on the screw 5, when the lower part of the locking nut 62 continuously moves with the screw 5, the pressure plate 63 presses the pressure rod 64 to move downwards, because the inclined groove 661 is arranged obliquely, and the central column 641 always slides in the inner cavity of the inclined groove 661, when the pressure rod 64 moves downwards, the movable column 66 moves towards the left side of the inner cavity of the movable groove 42, and finally the locking ball 67 is blocked in the locking circular groove 51 on the screw 5, at this time, the movable column 66 can realize the function of locking and fixing the screw 5, so that the anti-pulling member 3 is fixed, the stability of the connection performance of the anti-pulling member 3 under the action of larger external forces such as earthquake load and wind load is further enhanced, the anti-pulling member side capacity, the anti-collapse capacity and the anti-collapse performance of the steel structure building are improved, the operation is simple and the popularization mode is convenient and rapid to use;
when the locking balls 67 approach each other and enter the locking circular groove 51 on the screw 5, as the opposite magnetic poles of the piston magnetic plate 72 and the locking balls 67 are opposite, the locking balls 67 at the two sides can squeeze the piston magnetic plate 72 to move towards the middle part of the inner cavity of the extrusion cavity 52, at the moment, the compression springs 71 are gradually stretched, so that the air in the inner cavity of the extrusion cavity 52 is conveyed to the inner cavity of the anti-pulling cavity 54 through the air conveying channel 53, the air content in the inner cavity of the anti-pulling cavity 54 is increased, namely the anti-pulling blocks 73 at the two sides can be extruded to move towards the outer side of the screw 5, at the moment, the anti-pulling blocks 73 can penetrate into the foundation, namely the friction force between the screw 5 and the foundation is increased, and the reliability of the connection between the steel structure beam 1 and the foundation is improved, meanwhile, the seismic energy can be effectively dissipated, and the practicability of the whole device is improved;
after the anti-pulling pieces 3 on two sides are installed, the anti-pulling pieces 3 on one side can be prevented from being damaged by the arrangement of the connecting concave plate 81 and the connecting convex plate 82, the connection relation between the anti-pulling pieces 3 on two sides is improved, and the service life of any anti-pulling piece 3 is prolonged.
It should be noted that, specific model specifications of the motor need to be determined by selecting a model according to actual specifications of the device, and a specific model selection calculation method adopts the prior art in the field, so detailed description is omitted.
