Description
Technical Field
[0001] The utility model belongs to the technical field of steel structure workshop roof accessories, and particularly relates to a drainage and ventilation device for a steel structure workshop roof. Background Art
[0002] After a steel structure workshop is completed, improvements are often made to its drainage and ventilation systems. Currently, a common approach to roof drainage systems is to design the roof into a sloping roof, through which rainwater is diverted to an external manifold, where it is collected and discharged. However, as the design of steel structure workshops has gradually changed and the width of workshops has gradually increased, a pointed roof design requires the installation of diversion devices at the edges for side diversion. These diversion devices require a blocking device to divert rainwater, which is easily damaged by the strong impact of rainwater. To address these issues, existing steel structure prefabricated workshops are typically constructed with parapets around the roof surface. When rainwater falls from the sloping roof, it forms a drainage ditch through the parapets and the sloping roof. Lateral diversion ports are provided in the ditch to divert rainwater outward. However, these existing drainage ditches are prone to clogging, and rainwater has multiple landing points when discharged, which is not conducive to collecting surface rainwater.
[0003] In addition to windows, the existing workshop ventilation system also has an unpowered fan on the roof. This unpowered fan automatically adjusts its rotation speed according to the size of the external airflow, thereby adjusting the ventilation volume. To address this drawback, when rapid and large-scale exhaust or smoke exhaust is required in the workshop, the existing roof ventilation device cannot meet the exhaust requirements.
[0004] In response to the shortcomings of the existing technology, as a researcher in this field, I found the following problems after multiple constructions: if the exhaust equipment is installed on the wall of the workshop, when the exhaust equipment is running, it will affect the surrounding environment of the workshop. However, if the air outlet is set on the roof, this problem can be solved well. However, when setting the exhaust outlet on the roof, wind and rain protection must be considered to avoid air flow or rainwater backflow. Therefore, the location design of the exhaust outlet will be a technical problem that needs to be solved urgently in this field. Summary of the Invention
[0005] In view of the shortcomings of the existing technology mentioned above, the utility model proposes a drainage and ventilation device for the roof of a steel structure workshop.

The outer periphery of the exhaust valve 2 is provided with a fixed edge 21 that is riveted to the side wall of the gutter 1; because the exhaust valve 2 is located above the inside of the gutter 1, this area has a drainage function, so in order to prevent rainwater from flowing back through the exhaust valve 2 when impacted, the exhaust valve 2 is hingedly provided with numerous self-hanging exhaust louvers 22 inside. In the non-exhaust state and rainy and snowy weather, it is in a self-hanging closed state to prevent rainwater and animals from intruding.
[0029] The bottom plate bracket 32 and the side bracket 33 are used to jointly realize the sealing and fixing of the gutter bottom plate 31. The gutter bottom plate 31 cooperates with the side bracket 33 to realize the sealing and fixing and auxiliary support of the roof drainage and ventilation device of the steel structure workshop indoors.
