Dome greenhouse skeleton structure imitating gordon euryale leaf veins

Abstract

The invention is applied to the field of greenhouse skeleton structure design, and particularly relates to a dome greenhouse skeleton structure imitating gordon euryale leaf veins. The skeleton structure comprises a ring beam, middle stand columns, main beams, a greenhouse door and skylights, wherein the ring beam divides a circle into 20 equal parts, the stand columns are evenly arranged on each equal part and four quadrant points of the circle, the main beams are arranged above the ring beam, the main beams are divided into four layers and are obtained by quartering a 1 / 4 arc in the vertical direction, the overall structure is a triangular and quadrilateral truss unit, a greenhouse door is arranged between the two vertical main beams in the front view direction of the fourth layer on the upper portion of the ring beam, and four skylights capable of being opened and closed are arranged on the first layer of main beams. By means of the gordon euryale leaf vein structure, the dome greenhouse skeleton structure which is high in strength and high in illumination, saves materials and facilitates mechanical operation is provided, and analysis proves that forked structures and forked angles of the gordon euryale leaf veins not only can transfer the effect of concentrated stress and improve the overall structural strength, but also can save the materials on the premise of ensuring sufficient strength of the greenhouse.

Description

technical field [0001] The invention is applied to the field of greenhouse skeleton structure design, and specifically relates to a greenhouse skeleton structure imitating the vein dome of Gorgon fruit. Background technique [0002] The column-free arch circular greenhouse with steel structure has good lighting performance and is convenient for mechanized operation. It can achieve the frame effect of maximizing space utilization and minimizing surface area. It is the best model for three-dimensional farming in ecological agriculture. Due to the reduction of columns, the bearing capacity of the greenhouse It is the primary consideration in designing a circular greenhouse. [0003] At present, the main structure of the existing dome greenhouse is similar to the bird's nest structure, and its main beam is composed of regular triangle, regular hexagon or quadrilateral truss units. Greenhouses with bird’s nest structure whose main girders are regular triangle and regular hexagon...
