Embodiment 1

[0046] Embodiment 1: A kind of internally connected scaffold fastener, see Figure 2-Figure 4 , the two ends of a gap connection plate are respectively vertically connected with inner sleeve plates. The symmetrical outer side of each inner sleeve is respectively inwardly provided with cutouts, which divide the edge of the inner sleeve into two parts, the inner board and the outer board; the cutouts of the two inner sleeves are perpendicular to each other. Screw holes are provided on the inner plate and adjusting bolts are installed, and the end faces of the adjusting bolts are in contact with the inner surface of the outer plate.

[0047] Wherein, the inner sleeve plates located at both ends of the gap connecting plate are respectively rectangular inner sleeve plates, and the length directions of the two rectangular inner sleeve plates are perpendicular to each other.

Embodiment 2

[0048] Embodiment 2: another kind of internally connected scaffold fastener, see Figure 6 , On the basis of Embodiment 1, an anti-reversal mechanism is provided on the adjusting bolt. In the anti-reverse mechanism, a vertical connecting rod is vertically fixed at the end of the adjusting bolt, and a locking swing rod is hinged at the end of the vertical connecting rod.

Embodiment 3

[0049] Embodiment 3: Yet another internally connected scaffold fastener, characterized in that it includes a gap connecting plate, the two ends of the gap connecting plate are respectively vertically connected with inner sleeve plates, and the symmetrical outer side of each inner sleeve plate is welded with Shrapnel: The directions of the shrapnel of the two inner sleeves are perpendicular to each other, screw holes are arranged on the inner sleeves and adjusting bolts are installed, and the end faces of the adjusting bolts are in contact with the inner surface of the shrapnel.

[0050] An anti-reverse mechanism is arranged on the adjusting bolt. The anti-reverse mechanism is that a cam is hinged at the end of the adjusting bolt, and the cam is connected with a cam handle.

Abstract

The invention discloses an internally connected type scaffold fastening and a connecting structure thereof. The internally connected type scaffold fastening comprises a gap connecting plate, wherein the two ends of the gap connecting plate are connected to internally sleeved plates respectively in a perpendicular mode, outer plates are fixed and welded on the outer side faces of the two internally sleeved plates respectively, one pages of the outer plates are welded and fixed, the other pages of the outer plates can swing, the two internally sleeved plates are provided with screw holes and adjustable bolts respectively, and the end parts of the adjustable bolts correspond to the side faces of the pages, which can swing, of the outer plates. According to the internally connected type scaffold fastening and the connecting method thereof, quick and stable connection is achieved, the construction speed is fast, and the effect is good. The side face of a high strength concave-convex groove square rectangular pipe or circular rectangular pipe connecting structure is provided with a dent groove opening which is bent and molded, the inner part of the groove opening is provided with an inner part slide rail of which the direction is the same with the direction of the groove opening and the breadth is larger than that of the groove opening, and the inner slide rail is bent and molded. According to the structural design, the inertia moment can be sharply improved, and thus the bending resistant and torsion resistant strength of the square rectangular pipe is improved.

Description

technical field [0001] The invention mainly relates to the technical field of cold-formed steel structural profiles, and in particular to an internally connected scaffold fastener and its connection structure. Background technique [0002] Square steel and round steel pipe are both hollow and long strips of steel, which are the most frequently used pipe fittings in the engineering field. Square steel and round steel pipe not only have bending and torsional strength, but also are light in weight, so they are widely used in the manufacture of mechanical parts and engineering structures. Small-sized square steel and cylindrical tubes in the prior art are generally divided into hot-rolled seamless round tubes, cold-drawn seamless round tubes, extruded seamless round tubes, and welded round tubes. The cross-sectional shape of the round tubes is generally conventional In recent years, some circular tubes with other cross-sectional shapes have appeared, but their moment of inertia...
