Sliding-type roof draught fan system and installation method thereof

Abstract

The invention provides a sliding-type roof draught fan system, and relates to the technical field of metal roof enclosures. The sliding-type roof draught fan system comprises a roof purlin, a roof bottom plate fixed to the roof purlin, and a draught fan hole formed in the roof bottom plate, and comprises a draught fan bracket placed on the roof bottom plate at the draught fan hole but not fixed tothe roof bottom plate, a draught fan seat fixed to the draught fan bracket, sliding supports fixed to the roof bottom plate and located at the periphery of the draught fan seat, and an upper roof plate slidably matched with the sliding supports; the upper roof plate is provided with a hole and fixed to the periphery edge of the draught fan seat, and a waterproof structure is arranged at the jointof the upper roof plate and the draught fan seat. According to the sliding-type roof draught fan system, the draught fan can be deformed (slide) with the upper roof plate together, thus deformation stress caused by the thermal expansion and cold contraction of the upper roof plate in the length direction is released, the stress concentration of the roof plate around the draught fan hole is avoided, thus the connection fastness of the roof plate and the periphery of the draught fan hole is strengthened, and the waterproof effect is long.

Description

technical field [0001] The invention relates to a sliding roof fan system and an installation method thereof, belonging to the technical field of building steel structures. Background technique [0002] In steel structure workshops, roof fans have been widely used, which can effectively improve indoor ventilation effects, improve air quality, and provide a comfortable working environment. Conventional roof fan support and the main structure are generally directly connected by screws or welding, and the fan support and the main structure are firmly connected and cannot slide relative to each other. At present, a large number of common roof panels of public buildings often use 180° occlusal connections of aluminum-magnesium-manganese panels. The special sliding fixed support makes the roof panel and the main structure have a certain relative displacement to prevent thermal expansion and contraction deformation caused by temperature changes. , and the fixed connection between ...
