Ventilation steel structure

The ventilation steel structure aims to solve the technical problem that ventilation openings of a clerestory of a steel structure plant are inconvenient to adjust and comprises a steel structure plant body, the clerestory is arranged at the top end of the steel structure plant body, a transmission mechanism is arranged at the top end of the clerestory, and two sets of ventilation pipes are arranged at the top end of the steel structure plant body in a symmetrical structure relative to the transmission mechanism. The two sets of ventilation pipes are arranged in a uniform structure, adjusting mechanisms are arranged in the ventilation pipes, the input ends of the adjusting mechanisms penetrate out of the ventilation pipes and are connected with the output ends of the transmission mechanisms in a meshed mode, and the device has the advantages of being clear and compact in structural design and convenient to adjust. 本实用新型涉及一种通风钢结构，旨在解决钢结构厂房气楼通风口调节不便的技术问题，包括钢结构厂房本体，钢结构厂房本体顶端设有风楼，风楼顶端设有传动机构，钢结构厂房本体顶端相对传动机构呈对称结构设有
