Embodiment approach
[0040] In further embodiments of the present invention, please continue to refer to Figure 4 , Figure 5 As shown, the connecting piece 1 is rectangular, and the width of the connecting piece 1 is smaller than the width of the channel steel 31 and the channel steel 32, so that the connecting piece 1 can be put into the grooves of the channel steel 31 and the channel steel 32.
[0041] In a further embodiment of the present invention, the fixed plate 211 and the fixed plate 221 are circular, and the diameters of the fixed plate 211 and the fixed plate 221 match the width of the connecting piece 1, so that the fixed plate 211, the fixed plate 221 and the connecting piece 1 It can bear the fastening force to the greatest extent, and also prevents the bolts 21 and 22 from coming out of the channel steel holes.
[0042] In a further embodiment of the present invention, the threaded parts of the bolts 21 and 22 are coated with anti-falling glue, which increases the fastening force...

The invention discloses a double-splicing connecting piece and an application method thereof. The double-splicing connecting piece comprises a connecting piece body and two bolts. Two sides of the connecting piece are provided with two penetrating threaded holes. Edges of the two threaded holes upwardly extend so that a protrusion is formed. Upper end surfaces of heads of the two bolts are provided with inner hexagonal grooves. The double-splicing connecting piece and the application method thereof have following benefice effects: the double-splicing connecting piece and an application method thereof are suitable for connecting two channel steel back to back so that back connection strength for the two channel steel is ensured; better stability is obtained; channel steel holes are not easily abraded; the double-splicing connecting piece can bear higher vertical loads compared with conventional bolt-nut connection; unbearable transverse loads can be borne; non-standard bolts coated with oil-resistant glue are adopted so that the bolts do not easily fall; and the piece is small in size and convenient to use.
Description
technical field [0001] The invention relates to the technical field of channel steel, in particular to a double-split connecting piece. Background technique [0002] Channel steel is a long strip of steel with a groove-shaped cross-section. Its specifications are expressed in millimeters of waist height (h) × leg width (b) × waist thickness (d), such as 120×53×5, which means a groove with a waist height of 120 mm, a leg width of 53 mm, and a waist thickness of 5 mm. Steel, or 12# channel steel. For channel steel with the same waist height, if there are several different leg widths and waist thicknesses, a, b, and c must be added to the right of the model to distinguish them, such as 25a#, 25b# and 25c#. [0003] In engineering, it is often necessary to connect channel steel together to form a channel steel connection structure. However, the existing channel steel connectors are not designed in consideration of the characteristics of channel steel, and the degree of coopera...
