Steel Grate Stair Treads Introduction

The ladder pedal has four forms according to the front guard or not and the connection mode with the ladder beam, which are expressed as T1, T2, T3 and T4.From an economic point of view, it is recommended that modulus widths (125, 155, 185, 215, 245, 275 for Series 1) be used whenever possible.Series 2 uses 125, 165, 205, 245, 275mm, etc.) in 100mm multiples (such as 500, 600, 700, 800, 900, 1000, 1200mm, etc.).Step plate tolerance: width W±3mm, length L-3mm.

(1) commonly used stairs width is 700mm, 800mm, 900mm;
Width is 600mm, width should not be greater than 1200mm.
(2) for a single person through the stairs, the width between the two inclined beams or guardrail should not be less than 600mm.
(3) When the stairs frequently bear several people crossing at the same time or used as an evacuation route for personnel, the width of the stairs should be increased to 1200mm.
(4) The step plate is made of steel grid plate, and the type of steel grid plate can be selected according to Appendix E.
(5) the abrupt edge of the stair step should be able to bear the load of 1.5KN, when the width is not more than 1200mm, the load acts on the 100mm×100mm area;
When the width is greater than 1200mm, load 1.5KN in each symmetric 600mm place, the deflection of the stair step plate should not exceed 1/500 of the span.
(6) the stair pedal and the ladder platform should have good anti-skid performance.
(7) the tower connecting part of the vertical projection of the two adjacent stairs step plates should not be less than 10mm.
(8) The link between the step plate and the staircase is fixed by welding or bolt, as shown in Figure A.1.
When fixed by bolts, the bolt size shall not be less than M10.
