a greenhouse

Abstract

The invention provides a greenhouse and belongs to the technical field of agriculture. It solves the technical problems such as the large number of materials required for the construction of the existing greenhouse. This greenhouse consists of four corner columns, two beams and two longitudinal beams arranged between adjacent corner columns. The beams and longitudinal beams form a rectangular frame. The upper part of the rectangular frame is fixed with ceiling brackets. The two ends of the beams are fixedly connected to the corresponding corner columns. , the longitudinal beam is formed by splicing at least two hollow short beams, the two adjacent short beams are fixed by connecting pieces, the end of the short beam adjacent to the corner post is in contact with the corner post and the corner post is formed by the end of the short beam Support, a tension rope is connected between the adjacent corner posts and the tension rope is located in the longitudinal beam, the two ends of the tension rope are respectively fixed to the corresponding corner posts, and the tension rope is provided with a tightener that can tighten the tension rope . The invention has the advantage of ensuring the structural strength of the greenhouse while reducing the materials required for the greenhouse.

Description

technical field [0001] The invention belongs to the technical field of agriculture and relates to a greenhouse. Background technique [0002] The greenhouse is a commonly used cultivation room in modern agricultural production. By covering the greenhouse with a polyethylene film, the greenhouse can form an environment isolated from the outside world, reducing the loss of heat in the greenhouse, thus ensuring that the environment in the greenhouse is suitable for the growth of vegetables and other crops. , which can realize the planting of crops such as vegetables in any season. [0003] Greenhouses are made of lapped frame structures, generally divided into arched and ridge-shaped; arched greenhouses are composed of several parallel arches and steel wire ropes connected between the arches, such as the high-strength non-woven fabrics disclosed in Chinese patent documents. Column greenhouse frame [CN201499493U], the horizontal span of this type of greenhouse is relatively sma...

AI Technical Summary

Problems solved by technology

Since there is no substantial connection between short beams and short beams, the number of columns must be greater than or equal to the number of short beams to meet the strength of the greenhouse. The number of columns required to build a greenhouse is large, which makes the cost of the greenhouse higher; at the same time When building a greenhouse, you need to fix each column vertically on the base first, and then fix the short beams to the columns one by one. The operation of building a greenhouse is more troublesome
