Photovoltaic bracket square tube round tube greenhouse tube

What size tie rod should a solar greenhouse skeleton be made of?

According to our results, the tie rod should be made of a 30 × 2 mm round tube, while the tie bar reinforcement of a 20 × 2 mm round tube. In the present research, the effect of different geometric parameters of single tube sections on the safety of solar greenhouse skeletons was studied. The results are provided below: 1.

Does single tube cross section affect greenhouse skeleton safety?

The single tube section has various forms, but there is no scientific theory to guide the selection process. To the best of our knowledge, the scientific analysis of the impact of single pipe cross section on the safety of greenhouse skeleton has not been addressed so far.

Which type of pipe has the smallest effect on greenhouse skeleton?

The largest shape variations in the four pipe types were 30.952 mm, 33.073 mm, 21.942 mm and 20.598 mm. As Fig. 9 shows, the highest shape variation was that of the square tube. That of the elliptic tube was the smallest one. Therefore, under uniform snow load conditions, the smallest effect on the greenhouse skeleton was the elliptic tube.

Is a steel structure solar greenhouse suitable for fruit trees?

Guo, L. et al. A new steel structure solar greenhouse suitable for off-season cultivation of fruit trees. North. Hortic. 19, 45–48 (2019). Xie, H. & Liu, Y. Investigation and analysis on performance of arch plastic greenhouse in Daqing.

Can a single pipe skeleton replace a truss structure in a solar greenhouse?

In recent years, a new structure called single pipe skeleton has been used to replace the truss structure in the solar greenhouse. However, single pipe skeleton parts provide less safety as compared with traditional trusses.

Which steel is used to build a greenhouse skeleton?

Also, the wall thickness of the round, elliptic, square and Ω tube sections were 2 mm and the Q235 steel was used to build the greenhouse skeleton. Parameters of the Q235 steel used in the present research are shown in Table 1 and section sizes are shown in Fig. 1. Table 1 Q235 steel parameters.
