1. Pay-off on site, and correct the position and height difference of embedded parts. When the deviation of the center position of embedded parts is large, the iron plate welding widening method can be used to remedy, and the deviation of the height difference position of embedded parts can be remedied by column cutting method.

2. Connection between column and iron plate of embedded parts

Some iron plates are directly welded on the column, and the adjustment range of the column position is very small. There is also a field welding of the column and the bottom plate, which has a large adjustment range and a large proportion of use. Because the welding place between the column and the bottom plate needs to be painted with antirust paint, it will be poured with secondary cement pier in the later stage, so there is no need to worry about anticorrosion.

3. Installation of truss beam

Truss beam is the main load-bearing beam in greenhouse. The transverse truss is a span truss with a general length of 12m, and the longitudinal truss is a bay truss with a general length of 8m. Trusses and columns are connected by high-strength bolts. Note that the transverse truss needs to be equipped with accessories such as lifting wheels on the ground in advance before installation.

4. Installation of water tank bracket and water tank

Before installation, the water tank bracket should be pasted with water stop, and then installed on the top of truss beam and column. The installation of the gutter needs to pay attention to its slope and waterproofing to avoid affecting the drainage problem in the later period.

5. Installation of covering materials

Installation sequence of covering materials: first install the covering materials at the top, and then install the surrounding covering materials.
