after the bearing plate 1 is installed, a cable is laid in the bearing plate 1, the bearing plate 1 and the connecting portion 2 are driven to move relatively by dragging of the cable, so that the connecting plate 3 easily slides in the connecting buckle 4 by itself, and the connecting plate 3 is separated from the connecting buckle 4 in serious cases, therefore, a through hole 7 is formed in the connecting plate 3, a bolt thread penetrates through a bolt hole of the convex portion 5, the end portion of the bolt is inserted into the through hole 7, the connecting portion 2 and the bearing plate 1 are fixed, and the accident that the connecting portion 2 is separated from the bearing plate 1 is avoided; the convex part 5 is arranged to increase the threaded connection length of the bolt and the bearing plate 1 and reduce the possibility of thread slipping of the bolt and the bearing plate 1;
when the connecting part 2 is installed with the bearing plate 1, the other end of the connecting plate 3 is arranged at the position of the notch 8, so that the other end of the connecting plate 3 is conveniently embedded into the connecting buckle 4, and the connecting plate 3 can be easily arranged in the connecting buckle 4 even under the condition that an erection worker cannot clearly see;
because the two ends of the connecting part 2 are arranged in the bearing plate 1, the surface of the connecting part 2 protrudes out of the inner surface of the bearing plate 1, the cable has hardness, when the end part of the cable moves in the bearing plate 1, the end part of the cable is easy to be abutted against the edge position of the end part of the connecting part 2, so that the dragging of the cable in the bearing plate 1 is influenced, a guide plate 9 is arranged, the guide plate 9 ensures that the edge of the end part of the connecting part 2 and the inner surface of the bearing plate 1 have slope transition, and the end part of the cable crosses the connecting part 2 along the slope, so that the laying of the cable is convenient;
when a traditional cable bridge is erected, firstly, a plurality of rows of long screws are fixed on the top surface of a wall, then a support plate is horizontally installed at the lower ends of the long screws, the support plate is used for erecting and supporting a traditional cable bridge in the later period, when the bridge is erected in the later period, the end part of the cable bridge needs to penetrate through the space between two adjacent long screws one by one, a plurality of erecting workers cooperate to lift the cable bridge and push the cable bridge in the prior period, and if the cooperation of the workers is not tacit, the pushing of the cable bridge pushes the front workers, so that the high-altitude falling is easily caused; the risk can be reduced by matching the supporting block 10 with the pull rod 11, holes are measured and punched on the top of a wall, the horizontal end of the L-shaped part 12 is fixed on the top of the wall through expansion screws, then a plurality of workers only need to go up and down a bracket cable bridge to match the U-shaped part 13 with the supporting block 10, then the workers grasp the bearing plate 1 at the positions of the U-shaped part 13 and the supporting block 10 by one hand to make the supporting block 10 tightly buckled in the U-shaped part 13, the gravity of the bearing plate 1 is vertical and downward to increase the pressure on the grasping of the workers, then the other hand penetrates the bolt through the threaded hole of the vertical part 14 and rotates to penetrate the vertical plate of the bearing plate 1, and the bearing plate 1 is stably fixed at the moment, compared with the traditional mode, the installation and operation are more convenient, and the safety is higher;
the notch 15 is formed, so that when the supporting block 10 is matched with the U-shaped part 13, the U-shaped part 13 is limited to move left and right relative to the supporting block 10, when the bearing plate is installed, the swinging of the bearing plate 1 along the length direction of the bearing plate is limited, the U-shaped part 13 is prevented from being separated from the supporting block 10, and the situation that when a worker holds the bearing plate by one hand, the U-shaped part 13 is separated from the supporting block 10, and the bearing plate 1 is squeezed to contort the hand is avoided;
when the supporting block 10 is matched with the U-shaped part 13, the clamping plate 16 is embedded into the sliding groove 17, so that the pull rod 11 and the bearing plate 1 are relatively far away from each other and fixed, namely, after the supporting block 10 is matched with the U-shaped part 13, the bearing plate 1 and the pull rod 11 are limited and fixed in terms of front-back relative movement and left-right relative movement, so that a worker can vacate the hands to smoothly install the tightening bolts to fix the pull rod 11 on the vertical plate of the bearing plate 1, the operation is convenient, the efficiency is improved, and the risk of high-altitude operation is reduced;
the cable is provided with steel sheets 19 for fixing the cables, the cables are arranged at the port of the end piece 18 according to the type or sequence, then the cables are wrapped by the steel sheets 19, the other end of the steel sheets 19 is pulled down from the lower surface of the end piece 18, the cables are fixed, the situation that the cables are staggered due to self elasticity is prevented, then the through holes 20 are connected through bolts and threads, the other ends of the steel sheets 19 are mutually extruded by the two extrusion plates 21, the steel sheets 19 are fixed, the cables are fixed, the situation that the cables are laid and droop according to the sequence and type is guaranteed, and the error rate of electrician operation is reduced; the other end of the steel sheet 19 is placed between the two extrusion plates 21, and the anti-drop teeth 22 are embedded in the anti-drop grooves 23, so that the stability between the steel sheet 19 and the extrusion plates 21 is further enhanced.
