Description

Technical Field

[0001] This utility model relates to the field of flat steel technology, and specifically discloses a flat steel structure with good protective effect. Background Technology

[0002] Flat steel refers to steel with a width of 12-300mm, a thickness of 3-60mm, and a rectangular cross-section with slightly blunt edges. Flat steel can be finished steel products, or it can be used as raw material for welded pipes and as slab blanks for rolled thin plates. Main uses: As finished products, flat steel can be used to make hoops, tools, and machine parts, and in construction as structural components for building frames and ladders.

[0003] Traditional flat steel structures are mostly single flat plates or simple bends, which are prone to bending or breaking under external impact, resulting in insufficient protection and weak resistance to deformation. Furthermore, they are prone to corrosion when exposed to humid or chemical environments for a long time, affecting their lifespan. In addition, when splicing multiple sections of flat steel, they rely on welding or bolts, which are prone to loosening and stress concentration, resulting in low connection stability. Utility Model Content

[0004] This utility model proposes a flat steel structure with good protective effect, high overall bending strength, effectively avoiding deformation and fracture caused by local stress concentration, corrosion resistance, long service life, convenient splicing, and strong connection stability.

[0005] This utility model is implemented as follows: a flat steel structure with good protective effect includes a horizontal base plate, a vertical plate, and inclined reinforcing ribs. The horizontal base plate is a rectangular flat plate with its thickness decreasing linearly from the center to the two edges along the width direction. The vertical plate is welded to the center line of the upper surface of the horizontal base plate. The inclined reinforcing ribs are right-angled triangular steel plates with their two right-angled sides welded to the side wall of the vertical plate and the upper surface of the horizontal base plate, respectively. Multiple inclined reinforcing ribs are provided and evenly distributed along the length of the flat steel.

[0006] As a preferred embodiment of the flat steel structure with good protective effect according to this utility model, the center thickness of the horizontal base plate is 1.5mm and the edge thickness is 1.0mm.

[0007] As a preferred embodiment of the flat steel structure with good protective effect according to this utility model, the vertical plate has a height of 20mm and a thickness of 2.0mm.

[0008] As a preferred flat steel structure with good protective effect according to this utility model, the outer surfaces of the horizontal base plate, the vertical plate and the inclined reinforcing rib are all coated with a protective coating and a wear-resistant coating in sequence. The protective coating and the wear-resistant coating are respectively a zinc-aluminum-magnesium alloy coating and a polyurethane coating.

[0009] As a preferred embodiment of the flat steel structure with good protective effect of this utility model, the front end of the horizontal base plate is fixedly connected with a protrusion, and the rear end of the horizontal base plate is provided with a groove that matches the protrusion.

[0010] As a preferred embodiment of the flat steel structure with good protective effect according to this utility model, a magnetic strip is fixedly connected to the inner wall of the groove, and the magnetic strip is a neodymium iron boron magnet.

[0011] As a preferred embodiment of the flat steel structure with good protective effect according to this utility model, the outer wall of the magnetic strip is covered with an epoxy resin insulating layer.

[0012] The beneficial effects of this utility model are:

[0013] The horizontal base plate adopts a gradient design with a thicker center and thinner edges, which reduces the overall weight while ensuring the compressive strength of the central load-bearing area. The vertical plate is welded to the center line of the horizontal base plate to form a T-shaped frame, which significantly enhances the bending resistance of the flat steel in the vertical direction. The inclined reinforcing ribs are symmetrically distributed on both sides of the vertical plate, and their right-angled sides are welded to the side wall of the vertical plate and the upper surface of the horizontal base plate, respectively, to disperse and transfer the lateral impact force to the horizontal base plate and the vertical plate, thereby improving the overall bending strength and effectively avoiding deformation and fracture caused by local stress concentration.

[0014] The protective coating is a zinc-aluminum-magnesium alloy coating, which forms a dense anti-corrosion barrier through electroplating. The wear-resistant coating is a polyurethane coating, which can resist scratches, aging and chemical corrosion in the outdoor environment.

[0015] The protrusions and grooves at both ends of the flat steel are designed with a gap fit, which can realize quick alignment and insertion. The magnetic strip fixed in the groove is a neodymium iron boron magnet, which helps to position the splicing and counteract lateral displacement, thus speeding up the installation. In addition, bolt holes can be pre-set on the side walls of the protrusions, grooves, and horizontal base plates, and the connection stability can be further enhanced by tightening the bolts.
