1 Unit base x 6 rows : total weight = 80 kgs . total weight for 3 units : 240 kgs
Total holding posts :10 . Sharing load : 24 kgs /post .
Strenght and resistance : for winds of 50 m/s (typhoon no 10 condition) .
One unit base of 22 turbines is facing approx 290 N force for a direct hit .Total force for 432 turbines = 5 220 N force .
The average force applied per post is: 530 N . The posts are designed to take 10000 N / 2 meter .
Each unit base is welded to the posts in order to avoid screws and give flexibility during installation.
Each posts and frames is made of stainless steel 304 grade .the location being on sea shore ,corrosion is a primary issue .
The frame and mounting frame should have an expected life span of over 30 years .
Remark 2: the load is applied only on the parapet .No load on the roof slab and no work has been done on the roof slab ,preserving the roof waterproofness . Each post is attached to the wall by 4 concrete machine screw anchor .Each post is firmly and definitively anchored by a welded hook barre over the parapet .
