Embodiment 1

[0036] Embodiment 1: A kind of concave-convex channel steel at the corner, see figure 2 , bend the steel plate to enclose the four sides of the rectangular tube, and set a top corner as a bevel. At least one of the top corners is provided with a connecting weld of the steel plate. A concave notch formed by bending is provided on the inclined surface, and an internal slideway formed by bending in the same direction as the notch but wider than the width of the notch is arranged inside the notch; the notch includes two parts connected with the inclined surface The side of a notch; the internal slideway is a rectangular slideway, including two sideways of the slideway connected together, a bottom surface of a slideway and the top of two slideways; connect.

[0037] At the same time, in this embodiment, the other sides of the square tube are provided with a concave notch formed by bending, and an internal slide formed by bending in the same direction as the notch but with a widt...

Embodiment 2

[0038] Example 2: see Figure 4 and Figure 5 , On the basis of Example 1, a layer of cold-formed corrugated board can also be compounded and fixed on the bottom surface of the inner slideway. The cross section of the corrugation is a square corrugation, or a zigzag corrugation, or a curved corrugation.

Embodiment 3

[0039] Embodiment 3: An internal fork-shaped connection composite column with concave-convex grooved steel at the corner, see Figure 1-Figure 4 , set four corners as described in embodiment 1 with concave-convex channel steel, the slope of each corner with concave-convex channel steel is on the inside, fixed together by connecting rods, the two ends of the connecting rods are respectively vertically connected with inner sleeves The symmetrical outer side of each inner cover plate is respectively inwardly cut, and the cut divides the edge of the inner cover plate into two parts: the inner plate and the outer plate; the cuts of the two inner cover plates are perpendicular to each other, and the inner plate Screw holes are arranged on the top and adjusting bolts are installed, and the end faces of the adjusting bolts are in contact with the inner surface of the outer plate. The middle parts of the connecting rods are combined into one through the connection of reinforcing rods. ...

Abstract

The invention discloses sectional steel with concave-convex grooves at corner parts and an inside connection combination post thereof. The sectional steel is characterized in that a steel plate is bent and defined into four rectangular square steel pipe side surfaces; at least one top corner is made into an inclined surface; a bent and formed recessed notch is formed in the inclined surface; a bent and formed inside slide way which has the width being greater than the notch width and has the same direction as the notch is formed inside the notch; the sectional steel with concave-convex grooves at the corner parts are fixed together through connecting rods and are combined to form an inside crossed connection combination post. The fast and stable connection is realized by using the connecting rod with the inner sleeve plate; the construction speed is high; the effect is good, wherein through the structural design of the inside crossed connection combination post, the inertia moment can be greatly improved, so that the bending-resistant and twisting-resistant intensity of the square steel pipe 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 profiled steel with concave-convex grooves at the corners and an internal connecting composite column. 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...
