Bridge Elements for Pedestriansfinnish_translation.jpg

Siltaelementit jalankulkijoille

Bridge elements are an easy way for pedestrian traffic guidance over open canals. These are real products and are widely in use in Southern-Finland. We calculate the product weights using EPC method, which is easy way understand the calculation. It is good to start with easy products and then take more difficult products.

Type                           3141            3142               3147          3148 

Canal width                   1.2 - 1.5 m        2.0 - 2.5 m         3.4 - 3.8 m      4.2 - 4.6 m

Width for walkers           1220 mm          1220 mm          1220 mm         1220 mm

Overall length                 2440 mm          3660 mm           4880 mm         6100 mm

Overall height                1043 mm          1063 mm           1063 mm         1063 mm

Weight                            170 kg               275 kg                380 kg             490 kg

3142

1.5 x 170 kg x 1.1(2) = 286 kg            1,5 x 2440 mm = 3660 mm         4.00 % 

3147

2 x 170 x 1.1(2) kg = 381 kg               2.0 x 2440 mm = 4880 mm         0.26 %

3148

2.5 x 170 x 1.1(2) kg = 476 kg            2.5 x 2440 mm = 6100 mm         2.85 %

                                                                                         Average         2.37 %

The table has the weight of the shortest bridge element. Sometimes we are interested in to know weights of other products. Values ​​are visible, which are defined to the first product. Pascal's Triangle row factor 1,1(2) does not sureprise us.
