OVAL TUBE BASE GREENHOUSE ACCESSORIES OVAL TUBE GREENHOUSE CONNECTOR CLAMP
The base of oval tube in greenhouse is no stranger to those who have been exposed to greenhouse equipment. In the installation project of greenhouse equipment, the products of oval tube base in greenhouse are not only in great demand, but also play a very critical role.
1、 Installation structure of oval tube base in greenhouse
During the actual installation of the elliptical tube base of the greenhouse, the overall structure of the greenhouse needs to be considered. The column is one in the middle, perpendicular to the ground and high with the shed. Both sides of the column are diagonal columns, and both sides of the diagonal column are diagonal braces. In the general shed, a shed mountain is formed every 4-5 meters. Sheshan is composed of five pillars. In this way, the whole area is divided into several rooms. The gable of the house outside the shed is the supporting column of the whole shed. The columns in the shed are divided into columns, diagonal columns and diagonal braces. The distance between them is even. The height is determined by the arch shape of the arch circle, and generally the upper part of the inclined column is about 1.8 meters. The slope is 600 with the ground, and the diagonal brace is outside the diagonal column, with a height of about 1m. The main function of the elliptical tube base of the greenhouse in the structure of the greenhouse is to fix the arch bar and increase the wind resistance.
2、 Material characteristics of oval tube base in greenhouse
Phyllostachys pubescens and other bamboos are supported by greenhouses that have been used for a long time, but they are not durable enough. Now they are only used in small buildings such as self occupied buildings in rural areas and relatively backward urban areas. In the construction of modern buildings, the type of steel support pipe commonly used at present is the oval pipe in the greenhouse. Because the erection of steel support should not only meet the needs of workers, but also meet the stability and durability of steel support, so the choice of strong and hard steel pipe. In order to match the steel pipe material of the shed support, the base of the oval pipe in the shed is also made of galvanized materials with high hardness and processed through the hot galvanizing process. Hot galvanizing is also called hot dip galvanizing and hot dip galvanizing, which is a metal anti-corrosion method, mainly used for metal structures and facilities in various industries. It is to immerse the derusted steel into the molten zinc at about 500 ℃, so as to attach zinc layer on the surface of the steel member, so as to prevent corrosion.
3、 Precautions for installation of oval tube base in greenhouse
Durability shall be considered for installation of oval pipe base in greenhouse. The durability of the greenhouse is affected by the aging resistance of the base of the oval tube and the bearing capacity of the main structure of the greenhouse. In addition to its own strength, the durability of light transmitting materials is also shown in the fact that the light transmission rate of the material decreases with time, and the attenuation degree of the light transmission rate is a decisive factor affecting the service life of light transmitting materials. As the greenhouse has been operating in the high temperature and humidity environment for a long time, the surface anti-corrosion of the base of the oval tube in the greenhouse has become one of the important factors affecting the service life of the greenhouse.
The installation of oval tube base in greenhouse should pay attention to the thermal insulation performance. Improving the thermal insulation performance of greenhouse and reducing energy consumption are the direct means to improve the production efficiency of greenhouse. The heat preservation ratio of greenhouse is a basic index to measure the heat preservation performance of greenhouse. The heat preservation ratio of greenhouse refers to the ratio between the coverage area of light transmitting material of greenhouse with small thermal resistance and the coverage area of greenhouse enclosure structure with large thermal resistance and the sum of the ground area. The greater the insulation ratio, the better the insulation performance of the greenhouse.
