[0023] In this embodiment, a trapezoidal block 7 is installed on one side of the limiting block 32, and a trapezoidal groove 8 adapted to the trapezoidal block 7 is provided on one side of the second connecting ear plate 6.

[0024] The trapezoidal groove has a depth of 10-15mm and a trapezoidal angle of 8°-12°.

[0025] In this embodiment, the surface of the first connecting ear plate 5 is slidably connected to the interior of the second ultra-thin steel component 2, and the surface of the first connecting ear plate 5 is in contact with the surface of the second connecting ear plate 6.

[0026] The first connecting ear plate 5, the second connecting ear plate 6, the stabilizing plate 41, the one-way force transmission pin 31, the anti-slip cap 34 and other structural components are all made of high-strength alloy.

[0027] In this embodiment, the surfaces of the first connecting ear plate 5 and the second connecting ear plate 6 are provided with relatively aligned pin holes 9, and the unidirectional force transmission pin 31 passes through the pin hole 9.

[0028] By setting up the connecting component 3, utilizing the cooperation of the unidirectional force transmission pin 31, the limiting block 32 and the connecting nut 33, and the adaptation of the trapezoidal block 7 on the limiting block 32 and the trapezoidal groove 8 on the second connecting ear plate 6, reliable unidirectional force transmission between the first ultra-thin steel component 1 and the second ultra-thin steel component 2 is achieved. The force transmission path is clear and the structure has high stability.

[0029] In this embodiment, the stabilizing component 4 includes a stabilizing plate 41, a stabilizing bolt 42, and a stabilizing nut 43. The bottom of the stabilizing plate 41 is provided with a cross groove 44. The inner surface of the cross groove 44 is slidably connected to the surface of the first ultra-thin steel component 1 and the second ultra-thin steel component 2, respectively. The interior of the stabilizing nut 43 is threadedly connected to one end of the stabilizing bolt 42.

[0030] Material: Q235B, thickness: 4-6mm, plate length: 150-200mm, width: 80-100mm, bottom cross groove depth: 10-15mm, groove width is adapted to the external dimensions of the steel component section;

[0031] The inner surface of the cross groove is textured with anti-slip grooves 0.5-1mm deep to increase friction with the steel structure.

[0032] The surfaces of the first ultra-thin steel component 1 and the second ultra-thin steel component 2 are provided with slots for the first stabilizing bolt 42 to pass through.

[0033] In this embodiment, the surface of the stabilizing plate 41 is provided with symmetrical screw holes 10, and the stabilizing bolts 42 pass through the screw holes 10.

[0034] By setting up the stabilizing component 4, and utilizing the cooperation of the stabilizing plate 41, stabilizing bolt 42 and stabilizing nut 43, the stability of the first ultra-thin steel component 1 and the second ultra-thin steel component 2 after connection is further enhanced, and the reliability of the entire connection node structure is improved. In addition, the sliding connection between the first connecting ear plate 5 and the second ultra-thin steel component 2 and the fitting with the second connecting ear plate 6 facilitates positioning and adjustment during installation, thereby improving installation efficiency.

Finally, the connecting nut 33 is threaded to the other end of the one-way force transmission pin 31. By tightening the connecting nut 33, the trapezoidal block 7 of the limiting block 32 is tightly fitted with the trapezoidal groove 8 of the second connecting ear plate 6, thereby realizing the one-way connection between the first ultra-thin steel component 1 and the second ultra-thin steel component 2.

Then, the stabilizing bolt 42 passes through the screw hole 10 on the surface of the stabilizing plate 41 and is connected to the internal thread of the stabilizing nut 43. By tightening the stabilizing bolt 42 and the stabilizing nut 43, the stabilizing plate 41 is tightly fixed to the first ultra-thin steel component 1 and the second ultra-thin steel component 2, further enhancing the stability of the connecting node.
