Embodiment 1

[0036] Embodiment one: if Figure 1-Figure 3 The high-strength concave-convex groove square rectangular tube connection structure shown. Corner connector 5 between two converging rectangular tubes 1a.

[0037] Such as Figure 4 and Figure 5 As shown, the corner connector 5 includes a vertical plate and a horizontal plate, both of which are fixed as one and provided with connecting ribs. Adjustment holes are respectively arranged on the vertical plate and the horizontal plate, and flip clamps are installed in the adjustment holes. The overturning clip includes a rectangular overturning block 7 . A pair of corners of the flipping block 7 of the rectangle is set as arc chamfering,

[0038] One side of the rectangular overturning block 7 is fixedly connected with a rotary screw, and the rotary screw is matched and sleeved in the adjustment hole, and a fixed nut 6 is installed on the rotary screw.

[0039] Such as Figure 7 As shown, the side wall of the square tube 1a is p...

Embodiment 2

[0043] Embodiment two: if Figure 6 As shown, on the basis of Embodiment 1, a tapered perforated hole is set in the center of the turning brick, and the rotating screw is connected with the turning brick through the perforated hole.

Embodiment 3

[0044] Embodiment three: see Figure 8 , on the basis of Embodiment 1, modify the corner connection. A support 8 is provided on the side of the connecting rib of the corner connector 5, and a through hole is provided on the support 8, and a hooked pull rod 9 is matched and installed in the through hole, and the hook end of the pull rod is hooked on the square tube 1a or In the embedded groove of the circular rectangular tube 1b, the other end of the pull rod is fixed on the support 8 through a nut.

[0045] In addition, in this embodiment, the bottom surface of the embedded groove is used as the antinode bottom surface.

Abstract

The invention discloses a connection structure for high-strength concave-convex groove square tubes or round tubes. The connection structure comprises the square tubes or round tubes and a corner connector. Adjustment holes are formed in a vertical plate and a horizontal plate of the corner connector respectively, overturning clamping parts are installed in the adjustment holes and comprise rectangular overturning blocks, one sides of the rectangular overturning blocks are fixedly connected with rotating screw rods, two opposite corners of each rectangular overturning block are arc chamfers, the rotating screw rods are installed in the adjustment holes in a matched and sleeved mode, and fixing nuts are installed on the rotating screw rods. According to the structure, the square tubes or round tubes serve as main connection bodies, fast and stable connection is realized through the corner connector, the construction speed is high, and the effect is good. A sunken notch formed in a bent mode is formed in each side surface of the high-strength concave-convex groove square tubes or round tubes, an internal slide way formed in a bent mode is arranged in each notch in the same direction as the notches, the width of the internal slide ways is greater than that of the notches, the inertia moment can be greatly increased through the structural design, and therefore the bending strength and the torsion strength of the square tubes can be improved.

Description

technical field [0001] The invention mainly relates to the technical field of cold-formed steel structural profiles, in particular to a high-strength concavo-convex groove square-rectangular pipe or round-rectangular pipe 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 app...
