How To Connect The Earth Anchor And Skeleton Of Greenhouse

How to connect the earth anchor and skeleton of greenhouse:

At present, the greenhouse industry, civil engineering embedment and andor column connection mainly has two forms, one is welding and the other is bolted. A common bolt connection is used as an example. If four bolts are exposed to the zero plane, a pre-embedded plate with four holes is provided at the bottom of the column. Align the bolts with the eye level and tighten the screws. Greenhouse construction according to the drawings, determine the position of each column and marked with lime. Dig a pit 30-40 cm deep, and use stones as column feet to prevent the column from sinking. Then, the digging girder is installed on the back column, the head of the girder is on the column, the tail girder is on the back wall or on the back auxiliary column, and the purlin 3-4 roads are put on the girder. The spinal purlin is connected on the girder, forming a straight line, while other purlins are placed at discrete points. To prevent purlin from sliding down, a small wooden block can be nailed to the girder under purlin to seize the purlin wood. Buried anchor and after the roof of the pressure film line fixed wire, in the bottom of the trench flat a greenhouse equal length of 8 lead wire, its wear anchor, earth anchor is made of two ends of the ring shaped 8 lead wire, according to the buried arch bar spacing, every 3 meters, tie a brick or stick on the lead wire, placed between these fixed things.

Outside the back wall of the greenhouse; In accordance with the same method, the trench is dug and the earth anchor is buried, but the distance between the earth anchor can be increased to 2-3 meters. After being buried, the earth can be filled firmly, and the upper ring of the iron anchor is exposed to the surface. Grun suggested pulling a piece of No. 8 lead wire on the back roof of the greenhouse and burying both ends into the ground on the outside of the greenhouse gable, with a weight tied to the head. Secure the lead wire with lead wire or nylon rope, with one end tied to the lead wire and one end tied to an earth anchor buried outside the back wall. The rear roof skeleton material includes girder, girder and purlin. The wood used should be processed before the erection and construction of the rear roof skeleton. The middle column and the girder wood should be joined by the wooden tenon, so the matching girder and the middle column are selected as a group. First, a tenon hole is opened on the position of the middle column support at the end of the big head of the girder wood, and an inclined plane is cut at the front end of the corresponding side of the tenon hole to place the spinal purlin. Before the construction, dig a column pit 30~40 cm deep at the position of the buried column. After tamping the bottom, put two whole bricks as the foot stone of the column.
