YX51-226-678 open floor bearing plate, also known as YX51-226-678 floor bearing plate, YX51-226-678 profiled steel plate It is an open floor bearing plate model, its rib height is 51mm, composed of three waves, each with a wave pitch of 226mm, the effective coverage width of the entire profiled steel plate is 678mm, the unfolding width is 1000mm, and the utilization rate is 67.8%. This plate type has a long history and is still in use today, characterized by relatively high rib height and good rigidity, so the unsupported span in the construction stage is relatively large, and it is used as a formwork in the later use stage.

YX51-226-678 galvanized profiled steel plate is a formed steel plate that is called profiled steel plate to form a wave section along the width of the plate by rolling cold bending of the coated plate or coated plate.

Profiled steel sheet

The thickness of common boards for roofing and wall is 0.4~1.6mm; the thickness of 2~3mm or more is used for load-bearing floors or silos. The wave height is generally 10~200 mm. When not reinforced, its height to thickness ratio should be controlled within 200. When using the long house panel, the slope can be 2~5%, and the deflection is not more than l/300 (l is the calculated span).

YX51-226-678 galvanized profiled steel plate because the original plate is very thin, the quality of anti-corrosion coating directly affects the service life, in order to adapt to the processing and anti-rust requirements, the coated steel plate needs to be inspected according to the relevant regulations. Under normal circumstances, the thin steel plate can also be applied with anti-rust paint after pressing according to the requirements of use, or the original stainless steel plate is used.

When YX51-226-678 galvanized profiled steel plate is used as a house panel and wall panel in an industrial plant, the amount of steel used per square meter is about 5~11 kg in the case of general no thermal insulation requirements. When there are thermal insulation requirements, mineral wool board, glass wool, foam plastic, etc. can be used as heating materials. Profiled steel plates are combined with concrete to form composite floor slabs, which can eliminate wooden formwork and can be used as a load-bearing structure. At the same time, in order to strengthen the adhesion between the profiled steel plate and the concrete, it is advisable to pre-weld the bolt or press the two-way stiffener on the steel plate.
