Claims

[Scope of Claim for Utility Model Registration] 1. In a state where it is integrated with the back side of a splicing plate 2 for use in a square steel pipe constructed by casting or forging or a combination thereof, the upper and lower parts 2A and 2B of the splicing plate 2 are Bolt penetration holes are opened at symmetrical positions,
Upper part 2A of the bolt penetration hole of the splice plate 2
Nut joining part 3 is located on the back side of the bolt penetration hole located at
A high-tensile bolt 4 with a screw thread is screwed into the nut combination portion 3, and the upper and lower portions 2A of the splint 2 are provided on the surface of the splint.
, 2B, a pair of left and right spacer protrusions 5 are protruded along the boundary line of the square steel pipes. 2 The splint plate 8 for external use on a rectangular steel pipe, which is configured to correspond to the splice plate 2 for use inside the rectangular steel pipe, has a through hole 8A that corresponds to the bolt penetration hole of the splice plate 2 in a square plate-like body in the front. In addition to being perforated, this splice plate 8
2. The nut-combined splint joint for rectangular steel pipes according to claim 1, wherein a pair of left and right spacer projections 8B corresponding to the pair of left and right spacer projections 5 are protruded from the back surface of the square steel pipe.
