The Structure Of A Glass Greenhouse

The structure of a glass greenhouse mainly includes the greenhouse foundation, greenhouse steel structure, and aluminum alloy structure.
basis
1. Basic classification: There are two types of glass greenhouse foundations: independent column foundation and strip foundation. Independent foundations can be used for internal or side columns, while strip foundations are mainly used for side walls and internal partitions.
2. Design requirements: Before design, the geological data of the construction site should be carefully analyzed. Firstly, the geological survey report of the site (used for important large-scale greenhouse projects); The second is construction site testing (for general projects); Thirdly, based on experience and reference geological data from nearby projects (for small-scale projects). When designing the foundation, in addition to meeting the requirements of strength, it should also have sufficient stability and the ability to resist uneven settlement. The foundation connected to the support between columns should also have sufficient transfer of horizontal forces and spatial stability. The bottom of the greenhouse should be located below the permafrost layer, and the heating greenhouse can consider the impact of heating on the foundation freezing depth based on climate and soil conditions. Generally, the bottom of the foundation should be 0 Above 5 meters, the distance between the top surface of the foundation and the outdoor ground should be greater than 0 1 meter to prevent exposure of the foundation and adverse effects on cultivation. Unless otherwise specified, the distance between the top surface of the greenhouse foundation and the indoor ground should be greater than 0.4 meters. The embedded parts connected to the greenhouse steel structure are all set at the top of the foundation, and the design of the embedded parts is also an important component of the foundation design. The connection methods between embedded parts and the upper structure mainly include hinge joint, consolidation, and elastic connection. The design and construction methods vary depending on the connection method, but all embedded parts must ensure good connection with the foundation and ensure that the force transmitted from the upper structure is correctly transmitted to the foundation.
