1. By punching holes on the H-beam web, it can penetrate the load flat steel, punching holes on the load flat steel and the H-beam flanges, so that the two engage each other, by punching the load flat steel. The cross bar flat steel is inserted, so that the three materials can be inserted into each other, and the interleaved combination welding of different specifications of H-beam, load flat steel and cross bar flat steel with different spacings can be achieved to meet different customer needs.
2. Only take H150*75*7*5 H-beam as an example, the moment of inertia is 679cm2, while the steel grating flat steel for general floor maintenance is FB505, and its moment of inertia is 5.21cm3; under the same use environment, the former resists The ability to deform is 130 times that of the latter. Under the 1100mm span, the maximum load can be instantly impacted and rolled by a 25-ton truck.
3. Substructure: Weld a certain number of anchors on the angle steel or Z-shaped steel as the foundation of the heavy-duty grille, which is integrated with the concrete pouring, and does not need to make the ditch edge, which makes the product laying more convenient, and the foundation has more impact resistance.
4. The key point of the high-load and heavy-duty steel grating is the design of the interleaved combination holes of H-beam and flat steel. The design is ingenious and perfectly realizes the transmission and coordination of force.
5. The advantage of high-load and heavy-duty steel grating is that it is suitable for the drainage of roads, bridges, ports, docks, airports, mines, power plants, freight stations and other application environments where heavy-duty vehicles pass and have drainage requirements. Snow removal system. When used in viaduct construction, concrete can be poured directly, making the bridge body stronger and more impact-resistant, making on-site construction more convenient.
6. Due to its large opening area, the high-load and heavy-load steel grating effectively reduces wind pressure and water pressure, and has good drainage and snow removal effects. It has anti-corrosion and anti-rust functions and has a service life of up to 70 years. Its construction and maintenance is simple, economical, durable, high strength, and has the incomparable advantages of other products.
7. H-beam can be replaced with anti-skid type with pattern, the type of load flat steel can be expanded to anti-slip toothed flat steel, and the cross bar flat steel can be expanded to toothed flat steel, twisted steel, steel bar for construction and other materials. The spacing of the above three materials can meet different occasions.
