Description

Technical Field

[0001] This utility model belongs to the field of building engineering equipment technology, specifically relating to a formwork system for pouring concrete across a ventilation fan. Background Technology

[0002] As one of the six major systems in a mine, the ventilation system ensures the ventilation needs of the entire mine and plays a crucial role in the construction and production of the entire mine. Generally, ventilation fans are exhaust fans, and the exhaust air has a certain temperature. In recent years, in order to build more environmentally friendly and energy-saving mines, many mines have started to collect and reuse underground exhaust air, which requires the construction of heat extraction chambers at the top of the ventilation fans to collect heat sources.

[0003] Due to the influence of the exhaust wind environment, the heat exchange room project generally adopts a reinforced concrete frame structure to improve its durability. However, the concrete construction requires the erection of an integral formwork underneath. Due to the influence of the ventilation fan, the formwork needs to be designed to cross the ventilation fan and meet the requirements of load-bearing capacity and stability. Utility Model Content
