Application of all-steel anti-static raised floor

All-steel anti-static raised floor All-steel anti-static raised floor This floor is made of high-quality steel plates by stamping and welding, and high-strength lightweight materials are injected. High strength, excellent waterproof, fireproof and moisture-proof performance, suitable for computer rooms, program control rooms and monitoring rooms with high load requirements. 1. Floor material: the floor is made of all-steel members, the bottom surface is made of deep-drawn steel plates, the surface is made of hard steel plates, and the upper and lower steel plates are stamped and formed. Its floor matrix is made of imported cold-rolled plates by deep drawing and welding. The upper plate of the floor is superhard steel plate, and the lower plate is deep-drawn steel plate. The floor surface is sprayed with conductive epoxy resin and filled with foamed cement, and the surface can be decorated with various floor coverings. The lower plate is integrally formed by large presses of 800 tons and 350 tons. The structure adopts the unique nested structure of our factory, which makes the floor stronger and more beautiful. The upper plate is integrally stamped at one time, so that the positioning and connection of the upper and lower plates are more accurate and the accuracy is reliably guaranteed. The welding combination of the upper and lower plates adopts multi-head semi-automatic spot welding machine to make the upper and lower steel plates of the floor closely connected. After welding, a large punch is used, and the whole stamping process ensures the accuracy of the shape and size of the floor. Anti-corrosion treatment of floor steel surface After welding, the floor adopts automatic spraying equipment, which makes the coating uniform, has strong binding force and has high anti-corrosion and anti-rust ability. The inner cavity of the floor is filled with foamed cement, and the inner cavity is made of nontoxic No.425 Portland cement. The strength, curing degree, fine particle size and safety of cement meet the requirements of the national testing department. The foam pore system is uniform and dense, the cement density reaches 1.2g/3 after grouting, and the interior of the steel floor is completely plump after grouting. Stamping forming of upper and lower plates: the lower plate is integrally formed by a large press with 800 tons and 350 tons, and the structure adopts the hexagonal star structure patented by our factory, which makes the floor firmer and more beautiful in appearance. The upper plate is integrally stamped at one time, so that the positioning and connection of the upper and lower plates are more accurate and the accuracy is reliably guaranteed. Welding combination of upper and lower plates: the welding combination of upper and lower plates is welded by ten rows of multi-head semi-automatic spot welders controlled by microcomputer imported from the United States, which makes the floor structure firmer and the surface smoother. After the upper and lower plates are welded, a 400-ton punch is used, and the overall stamping process ensures the accuracy of the shape and size of the floor. Plastic spraying treatment on the floor surface: after welding, the whole perforated floor is sprayed on the floor surface through the spraying production line (controlled by the spraying equipment of Swiss Golden Horse), thus reliably ensuring the rust resistance and antistatic performance of the floor. Foamed cement filling in the floor: the floor with plastic spraying surface treatment is filled with foamed cement through the cement filling production line (consisting of special high-pressure air foam generator and imported foamed cement mixing equipment) to ensure the strength, density and uniformity of foamed cement and improve the overall bearing capacity of the floor. Decorative surface bonding: HPL board is bonded to the upper surface of the floor. In order to ensure the uniformity of the adhesive layer, automatic glue spraying equipment and automatic rolling of mechanical equipment are adopted to ensure firm adhesion and stable quality. 2. All-steel bracket and beam material: the beam is made of high-quality pipeline steel, and there is no weld around it. The whole beam is galvanized for anticorrosion treatment. The upper bracket and the lower bracket of the bracket are formed by one-step stamping with a die, and the sleeve is made of seamless steel pipe, and the whole bracket is galvanized for corrosion protection. A. Structural support and truss support, that is, truss connection support and truss support floor support installation mode, are mainly composed of floor, support, truss and screw. The bearing height is 90mm~ 1200mm, and the adjustable range is 20mm. B. The basic dimension tolerance of the raised floor is 600mm×600mm, the limit tolerance is 0.2 mm, the basic dimension of the plate thickness is 35mm, and the limit tolerance is 0.2 mm. The upper plate material (excellent cold-rolled plate SPCC-1dt1.2mm21.0mm2) and the lower plate material. The flatness of the floor surface is 0.3 mm, and the verticality of the adjacent edges of the floor is 0.3 mm. The floor facing is soft, non-slip, pollution-resistant, corrosion-resistant and wear-resistant. C. Under the conditions of temperature of 15℃ ~ 30℃ and humidity of 30% ~ 70%, The system resistance of the raised floor is1.0×1.0× 10 ohm d, and the mechanical properties of the floor (65438 hard plastic wheel with a width of 46mm is pressed back10 times under a load not less than 40 ... (2 When the horizontal movement is less than 1.5㎜, the vertical deflection is less than 1.0㎜, and the bending load at the center of the truss beam is greater than 130Kg, the grounding pole can be connected with the copper core wire of BV 1-35 or above.
