Modulus and cutting loss calculation of Molded grating

., . 
Molded grating has its standard panel size and the mesh size is also fixed, therefore, when doing cuttings, it's impossible to keep the integrity of the mesh if there is no exact calculation, or there will be much wastage after cuttings. 
...
In order to reduce the cutting wastage and to keep the beautiful appearance, sometimes we have to calculate the grating modulus for the integral lattices. 

() = X N() + 7mm()
Grating sizes(integral lattices)= inner mesh sizesXN(modulus)+7mm(rib width)

N = (-7)/
Modulus N= (Grating sizes-7mm)/inner mesh sizes (integral value)
38.1X38.1mm, 1227X3667mm: 700mm, . 
Take grating mesh size 38.1X38.1mm, panel size 1227X3667mm as an example. 
Pave a trench which width is 700mm with the grating, and the grating should be integral lattices, without cutting fingers. 

N=(700-7)/38.1=18
It's calculated that N=(700-7)/38.1=18

1227X3667mm692mm, 1227mm
3667/38.1/(18+1) = 5
So the grating (panel size 1227X3667mm) could be cut into 5 PCS(3667/38.1/(18+1)) for the trench(1227LX692mmW)

(5X1227X692)/(1227X3667) X100% = 94.35%
The utilization ratio of the grating is (5X1227X692)/(1227X3667) X100% = 94.35%

2.1.3
Mechanical calculation

(), 
Concentrated full panel load (point load), line load and uniform load

(). (75mmX300mm)., 12mm1%. 
Concentrated full panel load(point load) trial is mainly design for manned capacity. The trial area is like a man's footprint(75mmX300mm). The standard installation data is mainly comes from man's comfortable walking and security. The max. Deflection should be less than 12mm or less than 1% of the span. 

(50mmX300mm), ...
Concentrated line load trial is to use an equilateral triangle block and one of its angle will be pressed on the grating to test the deformation under the stress condition. It's mainly for the directional load, such as the tires or the pultruded gratings whose supporting material is in different directions..

.. 200kg. 500 kg. 
The uniform load trial provides the basic mechanical data for the platform design. Generally, the uniform load of the manned platform is not less than 200kg/sqm; The uniform load of the equipment maintenance platform is not less than 500kg/sqm. 

()1%6.1/3. 
Destructive static test value(concentrated full panel load) is generally more than 6 times when the value of the deflection is 1%. The max. Load should be less than 1/3 of the destructive static test value. 

STSS60001., . 
Nantong Machs do the above test with S60001 pressure instrument which is imported from STS in America. The load test data are all in the condition of the parallel bilateral support of the grating. The mechanical property data will be better than the listed data if it's the multilateral support. 


2.1.4
Mechanical property table of the Molded grating


(): 
The declaration of the mechanical property of the molded grating(same with the pultruded grating)


 
The listed data is all tested by the bilateral support..

 
  1. ..
 The tested gratings are produced by Nantong Machs and all listed standard data is the minimum value of Machs' enterprise standard. 

 
  1. ...T
he ultimate load is a kind of max. Load when the gratings lose efficacy in the condition of a certain supporting span, because the resin type and the different fiberglass content have a great influence on the ultimate load of the gratings. The listed data is the result of Machs' standard product. The ultimate load cannot be the design parameter. The limitation of gratings application is in the range of the max. Load of the table.
