Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments; based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0022] As shown by Figures 1-5 In a cold-drawn steel section of the present utility model, a first card slot 101 is provided on the upper side of the left side wall of the steel body 100, and a second card slot 102 is provided on the lower side of the right side wall of the steel body 100. Both the first card slot 101 and the second card slot 102 are arranged in an L shape. The L-shaped arrangement facilitates docking for assembly. Embedded slots 103 are evenly provided on the left and right side walls of the steel body 100. An embedded strip 104 is slidably connected to the inner wall of the embedded slot 103. The embedded strip 104 facilitates the limit fixation of the steel body 100. The inner walls of the embedded slots 103 are all arranged in an inverted trapezoid shape. The trapezoidal arrangement can prevent slipping due to left and right movement. The outer wall of the embedded strip 104 matches the inner wall of the embedded slot 103.

[0023] In this embodiment: Docking the first card slot 101 of a group of steel bodies 100 with the second card slot 102 of another group of steel bodies 100 only requires a short-distance movement to complete the docking. Then, the embedded strip 104 is inserted into the inner cavity of the embedded slot 103. The embedded strip 104 facilitates the limit of the steel body 100 and prevents the steel body 100 from shifting, which is beneficial to the alignment of the steel body 100. After cutting the steel body 100 in proportion, the steel bodies 100 can be installed staggeredly for connection, which is convenient for increasing the length of the steel body 100.

The clamping frame 107 is assembled in the inner cavity of the limit groove 106. The clamping frame 107 facilitates the limit of the embedded strip 104 and prevents the embedded strip 104 from shifting. It can make the device facilitate the limit of the embedded strip 104 and prevent the embedded strip 104 from shifting, which is beneficial to the assembly operation of the steel body 100.

[0026] On the upper and lower sides of the opposite side walls of the left and right clamping frames 107, screw holes are evenly opened, and the other ends of the screw holes extend to the main body of the steel body 100. Fixing bolts 108 are screwed on the inner walls of the screw holes, and the clamping frames 107 can be easily installed and fixed through the fixing bolts 108.

[0027] In this embodiment: After the clamping frame 107 is clamped and placed, the fixing bolt 108 is screwed into the inner cavity of the screw hole, and the steel body 100 and the clamping frame 107 are fixedly connected through the fixing bolt 108, preventing the clamping frame 107 from shifting and affecting the limit fixation of the inlay strip 104, which is beneficial for more stable assembly.
