Tower platform steel grating technical requirements
Steel Grating (also known as steel grating) with a light weight, large carrying capacity, safety non-slip, easy installation and removal, material saving, durable, air and light, easy to clean, beautiful appearance, get in some tower platform a wide range of applications, steel lattice panels make the tower platform, corridors, staircase, etc., has become a trend in building a modern chemical plant.
Tower platform steel grating production requirements
1, column spacing flat load platform steel grating spacing and bar determined according to the design requirements for industrial platform, load flat steel spaced not more than 40mm; flat tip load, load flat with the same specifications The flat steel edging; special occasions, or directly with steel wall panels edging, but edging plate load flat cross-sectional area of not less than the cross-sectional area.
2, the tower platform steel grating edging using seam height of not less than the thickness of the flat-sided loads fillet weld, the weld length not less than four times the load flat steel thickness; withstand loads without edging board in the case, Allow interval 4 load flat steel welded to one place, but spaced not more than 180mm; under the edging boards carry the load situation does not allow interval welding, and must be fully welded.
Tower platform walkway steel grating load requirements
Tower platform walkway grating to withstand design loads, the deformation can not be greater than the span deflection 1/200, the maximum can not exceed 10mm. In addition to meeting the above requirements, but also meet the following requirements:
1, the design load value 1.5,
steel grating without permanent deformation;
2, the design load value of 3.0, the steel grating no breaking.
Platform ladders treads tower design requirements
Tower platform ladders end treads must sided fully welded side panels, flat load edging in the same direction with each board must root bar welded steel ladder treads edging frontier guards if necessary throughout still. Single pass his uniform load capacity of not less than 3.0 kN/m2.
Precautions
Due to the special nature of the tower device platforms, many are some of profiled
steel grating, for future installation goes well, we should pay attention to those matters in production during transport it?
First, the design. The designer should be based on the tower platform steel grating use environment to design, different humidity, different temperatures, different installation address will affect them.
Second, pay attention to the direction and size of the force platform tower angle steel grating steel grating. If the phenomenon is not installed on the steel grating direction of the force and angle of deviation, then appeared in the late installation.
Third, in transit. Because the tower platform steel grating Unlike standard steel grating as the rules, there will be placed in transit problem occurs if you put a bad collision, friction is likely to cause inconvenience to the latter part of the installation.
Fourth, pay attention to post-maintenance. Tower platform steel grating after installation and use, it should be noted that maintenance and repair, so you can extend the life of steel grating.
