Calculation of Metal Construction
45 USD Solar panels are also different sizes: 2.3x1.15 meters or 2.2x1.3 meters.Take for the base 2.3x1.15 m, weighing 30 kg.It is necessary to calculate the metal structure, select by the size of the profiles and their cutting taking into account wind and snow loads and the reserve strength ratio.Wind and snow loads: we have different zones in Ukraine (photo in the deposit), to calculate we will take 120 kg/m2 snow, 50 kg/m2 - wind.Profile options for the framework:
1) stands: C-shaped, standard sizes of 100x50x15 mm or 120x43x13 mm thickness of 3 mm (this thickness because the stands will be stuck in the ground so that they do not deform).You can also use the Sigma profile stands (more hard)
2) Balk overhead: C-shaped, standard sizes 100x50x15 mm or 120x43x13 mm thickness 2 mm
3) Progns to which the panels are attached: C-shaped; Z-shaped or Omega-shaped.The size and thickness of the profile to choose optimal in order to fix it with a large distance on the horizontal is 3-4 meters.4) Undercosses between stand 1 and stand 2 (if they are generally needed?U-shaped profile 60x20x2 mm or C-shaped profile
5) Remotions back by diagonal, profile U-shaped 40x20x2 mm or C-shaped
What is the purpose of these calculations is to choose the optimal design with the size and profile cut, to find the balance between strength and reliability and metal density of the design.Selection of steel brands: s350gd+zn275 or DX51D+zn275
In the investment:
1) Map of wind and snow loads
2) Schematic image of the design (2 pages)
3) Photo of profiles
4) photo 6 profile with tables of size selection

I will make the calculation of the metals. A question of welding or clinging in nodes and connections?

Hello to Igor!
on this topic since 2016. He also worked with typical designs (as in your request), and also developed fundamentally other models. The whole path passed: from the sketch of the table and the selection of the seats of the elements (including the modeling of the seats themselves) - to the production of profiles and the installation of the tables. And these structures have already been tested over time.
I am pleased to work with you, call me!

У вас есть геометрические характеристики данных сечений? Это нужно для статического расчета элементов конструкций.
-
Я так понимаю данных по моментам сопротивления на эти профили нет? Ну в противном случае эти данные были бы предоставлены в задании, поскольку без них считать на прочность конструкцию невозможно.
А вообще мне до сих пор сложно понять зачем использовать профиль, который стоит дороже профильной трубы, при этом несет меньшую нагрузку, чем профильная труба той же массы.
-
О, появилась стоимость - теперь данные момента сопротивления на профили давать не обязательно, потому как тот, кто решится сделать расчет за 2 тыщи грн, вряд ли понимает зачем это нужно))
-
Понятное дело, что за 2к уважающий себя расчетчик не будет выполнять этот расчет, но это уже второй вопрос. Тут такое дело: если у заказчика нет этих данных, то геометрические характеристики можно определить, например, в сателлите КТС-САПР программы Лира САПР, но это, естественно, дополнительная работа.
-
Год назад я делал проект солнечной электростанции и как раз за 2 тыщи. Но есть нюанс - до этого я никогда не делал в солиде чертежи и документацию, только проекты для себя, а научиться за чужие деньги было вкусно. Собственно так и берутся люди за работу, которую никогда ранее не делали.
Будем надеяться, что заказчику повезет с учеником))

Если цена железобетонная из бетона высокого класса, то да, вся надежда на ученика.
