Exemplarily, the tail portions of the two locking ear plates 100 form a cross-shaped structure, which serves as the main body of the drum-shaped support node 300. The cross-shaped structure forms four stress intervals, and a plurality of inner diaphragms 310 are arranged in each stress interval. The side edges of each inner diaphragm 310 abut the locking ear plate 100 corresponding to the stress interval, that is, the plurality of inner diaphragms 310 are located in the four regions formed by the cross-shaped structure, and the side edges of the inner diaphragms 310 abut the plate surfaces of the two adjacent locking ear plates 100 used to form the cross-shaped structure. The head portion of the locking ear plate 100 is provided with a first pin shaft hole 121, that is, the first pin shaft hole 121 is arranged on the locking ear plate 100 away from the drum-shaped support node 300, and the first pin shaft hole 121 is used to fix an external cable tensioning workpiece through a shaft pin. Exemplarily, the cable tensioning workpiece can be a cable.

Exemplarily, the inner diaphragm 310 of the present application is provided with 16 pieces, and the inner diaphragm 310 is evenly distributed in the four regions in the drum-shaped support node 300. In some embodiments, the number of inner diaphragms 310 can also be 20, 24, etc. without limitation.

[0030] Therefore, by intersecting the tail portions of the two locking ear plates 100 with each other to form the drum-shaped support node 300, and arranging a plurality of inner diaphragms 310 in the drum-shaped support node 300, the side edges of each inner diaphragm 310 abut the plate surfaces of the two adjacent locking ear plates located at the tail portions, and the first pin shaft hole 121 is arranged on the head portion of the locking ear plate 100, so as to form a complete locking ear plate structure, and the cross-shaped structure of the drum-shaped support node 300 and the plurality of inner diaphragms 310 ensure that the node has sufficient rigidity and strength under complex stress environments such as cable tension and shear force, thereby improving the safety of the cable tensioning construction process.

[0031] It can be understood that, with reference to the drawings Figures 1 to 5The lock ear plate 100 comprises a connecting plate 110, a head plate 120 and a tail plate 130, the head plate 120 and the tail plate 130 are connected to two ends of the connecting plate 110 respectively, thereby forming a head and a tail of the lock ear plate 100, wherein the tail plate 130 is a rectangular plate, the width of the connecting plate 110 is smaller than the width of the rectangular plate, when the rectangular plate is connected with the connecting plate 110, the side edges of the connecting plate 110 and the side edges of the rectangular plate are provided with arc-shaped structure transition when being connected, the smooth arc-shaped modeling avoids stress concentration, further improves the connection strength and rigidity of the cable ear plate structure, two rectangular plates are vertically and perpendicularly and intersectingly arranged to form the drum-shaped support node 300, the side edges of the inner partition plate 310 are connected with the plate surfaces of the adjacent rectangular plates respectively, at this time, the first pin shaft hole 121 of the lock ear plate 100 is arranged on the head plate 120, the head plate 120 is provided with a pin shaft inserted in the first pin shaft hole 121, and then is fixedly connected with the external cable end. Therefore, the drum-shaped support node 300 is formed by the vertically and intersectingly arranged rectangular plates, further ensures the structural stability of the drum-shaped support node 300, meanwhile, the rectangular plates and the connecting plate 110 are connected through the arc-shaped structure transition, and the inner and outer contours of the lock ear plate 100 are smooth, avoiding stress concentration, so that the lock ear plate 100 has good connection stability when being pulled by the cable.

[0032] It can be understood that, referring to Figure 5 The inner partition plate 310 is a fan-shaped structure, wherein two side edges of the fan-shaped structure abut against the surfaces of two adjacent tails of the lock ear plate 100, thereby fixing the inner partition plate 310 on the drum-shaped support node 300, meanwhile, the inner partition plates 310 located in each stress interval of the cross-shaped structure are arranged in layers and intervals in the up-down direction, so as to ensure stress average, through the cooperation of the drum-shaped support node 300 main body formed by the plurality of fan-shaped inner partition plates 310 and the cross-shaped structure, a more solid drum-shaped support node 300 is constituted, since the fan-shaped structure has an arc-shaped contour, stress concentration is avoided, thereby improving the stability of the entire drum-shaped support node 300.

[0033] It can be understood that, referring to Figure 1 , Figure 2The cable lashing ear plate structure further comprises a plurality of arc-shaped side plates 320, both ends of each arc-shaped side plate 320 abutting against the tail of the adjacent locking ear plate 100, that is, abutting against the corresponding stress interval, and the arc-shaped side plate 320 is arranged on the inner partition plate 310, that is, the inner side wall of the arc-shaped side plate 320 abuts against the inner partition plate 310 in the corresponding stress interval. It should be noted that the arc-shaped side plate 320 is welded with the four box beams outside when it is installed on the drum-shaped support node 300. Correspondingly, the part of the arc-shaped side plate 320 above the two locking ear plates 100 is connected with the roof grid bracing rod. By arranging the arc-shaped side plate 320 on the four side areas of the cross-shaped structure (the drum-shaped support node 300), the inner partition plate 310 is covered, and the connection stability of the entire drum-shaped support node 300 is strengthened, thereby improving the rigidity of the entire node.

[0034] It can be understood that, referring to Figure 1 、 Figure 2 The cable lashing ear plate structure further comprises a tensioning ear plate 200 arranged on both sides of the plate surface of the locking ear plate 100. Since there are two locking ear plates 100, there are two pairs of tensioning ear plates 200, one pair of tensioning ear plates 200 is arranged on each locking ear plate 100. The head of each tensioning ear plate 200 is provided with a second pin hole 210, that is, the second pin hole 210 is arranged at the tensioning ear plate end away from the locking ear plate 100. The second pin hole 210 is also used for fixed connection with the external cable tensioning workpiece. By arranging the tensioning ear plate 200 on both sides of the locking ear plate 100, when the cable lashing ear plate structure is connected with the external cable lashing, in addition to being connected and fixed through the first pin hole 121 on the locking ear plate 100, the second pin hole 210 on the tensioning ear plate 200 can also be used for cable fixation, thereby improving the safety of the cable tensioning construction process.

The cross-shaped structure in the drum-shaped support node 300 forms four areas, each of which is provided with a plurality of inner partition plates 310. The inner partition plates 310 in each area are arranged in layers along the up-down direction of the drum-shaped support node 300. One tension ear plate 200 is arranged horizontally and vertically on each of the two surfaces of each lock ear plate 100.
