1 Scope 1.1 General This quality and test apply to static loading statement and production of gratings made of steel, stainless steel, Aluminum and brass. Gratings, with the quality mark of quality community Gratings eV in the requirements must ments of quality and testing, and - depending on their Range - the relevant DIN standards, requirements of Workplace Regulation and the Workplace Guidelines as well as the accident prevention regulations of the employers' liability insurance society - in the current version - match. 1.2 Terms and definitions Gratings are cantilevered, different duty (Eg walk or drive) plate-shaped body with many through-holes in a regular arrangement. Gratings are used as covers for platforms, walkways, Stairs, landings, steps and other openings used. They usually consist of load bearing, cross bars and the edge-Clamping solutions. They are distinguished by welding pressing, pressing, through-

pluggable and Einsteckrosten. 2 Quality Regulations 2.1 Materials and dimensions There are to use standardized materials. You are taking into account the anticipated loads and the for application processing method coming from the goodnesssign user select. For these materials, the values and tolerances binding Lich that laid down in the relevant DIN standards are. Only the gratings deposited under section 4 criteria heFill meet these quality and testing. 2.2 Versions 2.2.1 welded gratings Welded gratings consist of non-perforated and unslit, vertically standing flat profiles as supporting rods in preferably twisted square or round bars as a crossbars pressed into the weld molding process, while be welded. Through the weld at each node datapoint arise homogeneous, stable and torsionGratings, which subsequently also well suited for cuts. The size map of the supporting rods to the transverse rods described in Table 2. 2.2.2 gratings Gratings are gratings in which the unattenuated crossrods pressed under high pressure into the slots of the support rods are. In special cases, the corresponding higher Crossbars be pre-slit. Caused by the compression of stable and torsionGratings, which subsequently also well suited for cuts. The size map of the supporting rods to the transverse rods described in Table 2. 2.2.3 plug-in shelves 2.2.3.1 Einsteckroste In Einsteckrosten are either the supporting rods or suspension and Slotted crossbars. A fixed connection may be through a Form-fit to compressions, friction, by jamming and are created by welding. 2.2.3.2-through grids For through rusting cross bars are capped by holed bars and pushed through by turning directly bar positioned / secured. 2.2.3.3 Dimensions The size map of the supporting rods to the transverse rods

described in Table 2. 2.2.4 Grating stair treads Steps are the same design as described in AnSection 2.2.1 to 2.2.3 describe manufactured. Steps are with a non-slip nosing and perforated mounting plates made. Scope subjected to other types of nosing entered be used. The following steps need to nosing their loads ontake (deviating from DIN 1055-3): - For every barrel width w 1200 mm more individual loads with 1.5 kN and contact areas of 100 x 100 mm, simultaneously acting along the step edge in the same At intervals of 600 mm.

The deflection of the support structure and the steps may be used according Load no more than 1/300 of span, max. 6.0 mm, respectively. 2.3 Design and selection criteria In addition to the aforementioned embodiments are following offselection criteria to consider: 5 Quality and Inspection Quality and Inspection for gratings B55E Standards-Download-Beuth-Meiser Vogtland-OHG-KdNr.7431708 LfNr.4236823001-2008-11-13 13:24 Page 8

2.3.1 Dimensioning of the mesh - Mesh size (the clear distance between bars), - Mesh spacing (distance between centers of the bars). 2.3.2 edging Gratings are embedded in non-load bearing and cross bar direction with edged of a frame, this also applies to sections. The Edge rods are welded together at the corners. 2.4 Tolerances In the preparation of the gratings, only the corresponding

Annex 1 listed manufacturing and supply tolerances topermeable. 2.5 Corrosion Protection Gratings made of steel condition, unless otherwise agreed, corrosion protection by galvanizing according to DIN EN ISO 1461. 3 detection methods The following are the basis for calculating lattice are gratings described. However, the detection method can also alternate with Calculation methods (eg FEM) and / or tests carried be performed. However, the following principles of calculation calculations shall be taken into account. 3.1 Load types The following types of load (traffic loads) may occur: - Uniformly distributed load in kN / m 2 , - Walk-gratings (deviating from DIN 1055-3): 1.5 kN point load at the most unfavorable point on a load terminals engagement surface of 200 mm x 200 mm. - Passable covers and load application areas for DIN 1055-3 and DIN 1072: Single loads (wheel load) - Special charges and attack surfaces of the condiunits. 3.2 Proof by the method of Partial safety factors When verification is distinguished: - The ultimate limit state, - Limit state of serviceability. The assessment must be conducted in the following steps are to: - Preparation of structural and load models for the in the relevant limit states design situations tions, - Proof that the Grenzustände not exceeded be if the design values of actions, the material properties and the geometric Whote be used in the models. 3.3 design values 3.3.1 Design values of actions The design value F d

an exposure is calculated as follows net: F d =Γ F ·F k Where: γ F The partial safety factor of the observed effect, F k the characteristic value of the action. For the ultimate limit state is in the Rule γ F =Γ Q = 1.5 is set when it is the action of is a traffic load. For limit state of serviceability γ is typically F = 1.0 is set, ie, the characteristic Γ value of the action F is then directly as rated sungswert used. 3.3.2 Design values for resistors / Material properties The design value X d the material property is generally calculated as follows: It is X k the characteristic value of the material property, γ M The partial safety factor for the characteristic construction material property.

For the limit state of bearing capacity and limit state of serviceability is for steel γ M = 1.0 applied. 3.4 the ultimate limit state In the ultimate limit state is the failure of Git terrosts check. It must be demonstrated, that E d ≤R d It is E d the design value of the load, here the maximum voltage, R d the design value of the load resistor, here the allowable voltage. 3.5 Limit state of serviceability Serviceability limit states correspond to condiconditions, in excess of the specified usage requirements are no longer met. In this case, the maximale deformation considered. It must be demonstrated be that 6 Quality and Inspection B55E Standards-Download-Beuth-Meiser Vogtland-OHG-KdNr.7431708 LfNr.4236823001-2008-11-13 13:24 Page 9
