Vegetable greenhouse structure system with chord support steel structure

Abstract

The invention discloses a vegetable greenhouse structure system with a chord support steel structure. The vegetable greenhouse structure system mainly comprises vertical supporting rods, a rigid component, a flexible component, a right supporting column and a left supporting column. Prestress is applied to the flexible component, and the load of the rigid component is reduced; the vertical supporting rods are round steel tubes and are arranged at equal intervals in parallel in the vertical direction; the rigid component and the vertical supporting rods are connected through upper steel pipes welded to the bottom surface of the rigid component; the vertical supporting rods are connected with the flexible component through lower steel pipes welded to two-way pipes; the flexible component issleeved with the two-way pipes; the left and right ends of the rigid component and the left and right ends of the flexible component are connected to the chord support steel structure, one end of thechord support steel structure is connected with the right supporting column through a fixing hinge support, and the other end of the chord support steel structure is connected with the left supportingcolumn through a sliding hinge support. The system has a large span, a self-balance structure system is also formed, the arch loss is reduced, materials are saved, and the system has the advantages of being high in structural strength, long in service life, relatively low in structure self-weight, large in rigidity and shape stability, easy to construct and the like.

Description

technical field [0001] The invention belongs to the technical field of facility agricultural engineering, and in particular relates to a string-supported steel structure vegetable greenhouse structure system. Background technique [0002] Since the 20th century, people's demand for large-scale public buildings has promoted the development of long-span structures. With the emergence of various high-strength and lightweight new materials and the advancement of structural theory, it has created favorable conditions for the development of long-span structures. conditions, and has accumulated a lot of experience for people in exploring large-span structural systems. Scholars have seldom studied the structure system of vegetable greenhouses. Currently, there are two common structures used in vegetable greenhouses: one uses bamboo poles and wood as arch materials. Poor, easy to decay, needs maintenance and replacement every year, inconvenient operation and management and other sho...

Problems solved by technology

Scholars have seldom studied the structure system of vegetable greenhouses. Currently, there are two common structures used in vegetable greenhouses: one uses bamboo poles and wood as arch materials. Poor, easy to decay, needs maintenance and replacement every year, inconvenient operation and management and other shortcomings; another kind of arch material is made of hot-dip galvanized thin-walled steel pipes, although in terms of strength, wind and snow resistance, anti-corrosion performance, etc. Meet the requirements, but there are still shortcomings such as insufficient service life and long construction time
