Description

Ridge node of double-slope metal pitched roof and its installation method

technical field

The invention relates to a ridge joint of a double-slope metal inclined roof and an installation method thereof, belonging to the technical field of metal roof enclosure.

Background technique

At present, metal roofing materials have been widely used in industrial and civil buildings. Its appearance and economy are good. However, its waterproof and sealing performance needs to be improved urgently, especially if the sloping ridge joints are not handled properly, it is easy to cause large-scale water leakage on the roof, resulting in economic losses. .

The traditional method of sloping ridge joints is to fix the outer ridge plug and the roof panel with self-drilling screws, and then lay ordinary butyl cement between the outer ridge plug and the ridge cover plate to perform sealing and waterproof treatment. This joint treatment The biggest disadvantage is that the connection between the outer ridge plug and the metal inclined roof panel is not vertically connected, the gap is relatively large, and it is difficult to connect the outer ridge plug and the peak of the roof panel. If waterproof glue is used alone to deal with the waterproof problem here, there is great uncertainty in the durability of waterproofing. Therefore, the traditional steel structure double-slope metal sloping roof ridge leaks, most of which are concentrated on roofs similar to sloping ridges, etc. At the opening, it is obvious that such a product level can no longer meet the requirements of economic and social development.

Based on this, this case arose.
