Ventilating dormer

Abstract

The invention discloses a ventilating dormer which comprises frameworks, framework pieces and daylighting panels. A plurality of whole bodies formed by fixed connection of the frameworks and the framework pieces are inserted in roof purlins at intervals in parallel. Two side walls of each framework are provided with ventilating openings. The daylighting panels fixedly cover the portion above the space formed by the frameworks and the framework pieces. Each framework piece is provided with at least one long strip hole and further provided with louver blades, and the louver blades can be detachably and fixedly inserted in the long strip holes. The louver blades exactly cover the ventilating openings in two sides of each framework. According to the ventilating dormer, the long strip holes allowing the louver blades to be installed are formed in the framework pieces, the louver blades can be quickly installed on the ventilating dormer, and the louver blades cover the ventilating openings, so products in a plant can be prevented from being contaminated by rain, snow, sand and dust, and the ventilating dormer is safe to use, convenient to operate and stable in structure.

Description

technical field [0001] The invention relates to an air tower, in particular to a ventilation air tower. Background technique [0002] The workshop is mainly ventilated through the air building. The common automatic ventilation structure of the air building is to set a horizontal vent on the upper part of the air tower. The vent is opened and closed by covering the window and breaking away from the horizontal vent. After rainy and snowy weather or windy sand weather, rain, snow or sand will accumulate on the outside of the window. When the window is opened, the accumulated rain, snow and sand will fall into the room and pollute the indoor items. When the window is opened , External dust and rain and snow will also fall into the room and cause pollution to indoor items. Contents of the invention [0003] In order to overcome the above-mentioned defects, the present invention provides a ventilation building, the ventilation building is provided with louvers, which has a simp...
