Description

Technical Field

[0001] This utility model belongs to the field of silo technology, specifically relating to a silo ring beam section, a silo ring beam including the above-mentioned silo ring beam section, and a silo including the above-mentioned ring beam. Background Technology

[0002] The steel support ring beam is a crucial structural component of a steel silo, primarily responsible for bearing the weight of the upper silo and the lower conical hopper, as well as the material load. High-quality steel is typically used, requiring high strength and rigidity to withstand significant loads and ensure overall structural stability. The design of the steel support ring beam should ensure even load distribution, avoiding localized stress concentrations. In earthquake-prone areas, the seismic performance of the steel support ring beam must also be considered. The ring beam structure should be applicable to larger silos to reduce operating costs, while modular assembly should simplify installation and reduce costs. While there are various forms of ring beams, current structural designs do not fully consider the aforementioned factors. Therefore, there is an urgent need in the market for a systematic solution to ensure the safe storage of grain within silos and the structural safety of the steel ring beam itself.

[0003] The existing structure of silo ring beams does not fully utilize the cross-sectional characteristics of the ring beams themselves. Under the premise of ensuring the safety of grain storage in the silo and the structural safety of the steel ring beams themselves, we should expand their application scope, reduce usage and installation costs, and extend their service life. Utility Model Content
