一. The main load-bearing parts of the glass greenhouse
1. The main column The columns of the glass greenhouse are divided into the main column of the axis and the wind-resistant column in the middle of the wall. The main column is the main load-bearing structure. The function of the wind-resistant column is mainly to stabilize the wall glass and prevent the surrounding beam from sagging, so the specifications of the wind-resistant column are relatively small. At present, the specifications of the main columns of the glass greenhouse are hot-dip galvanized square tubes, 120*120, 150*150, and the thickness ranges from 3.0~4.0.
2. Truss beam The truss beam is a beam connecting the columns and the columns. The truss beam generally adopts a composite structure of upper and lower Xuan. The upper and lower Xuan generally adopts square tubes, and the middle diagonal brace adopts angle iron or square tube. The length of the truss beam is 8 meters, 9.6 meters, and 12 meters, and the width ranges from 0.5 to 0.7 meters.
3. Gutter The gutter has a dual role. The first role is to bear the weight, which mainly bears the weight of the herringbone beam and the top covering material. The second role is drainage.
二. Processing and manufacturing process
1.The greenhouse columns and gutters are made of finished hot-dip galvanized steel from standard steel mills and are punched.
1.The manufacturing process of greenhouse truss beams is to heat-dip galvanize the entire black tube after welding.
