The arrangement of metal tile ridge keel is very important in the installation process of metal tile, which determines whether the installation of face tile is completed, whether the size is appropriate, and whether the tile surface is installed neatly. Firstly, the ridge keel adapts the specific size of keel according to the ridge height, and the ridge keel and roof keel are welded to ensure the overall strength, The welding parts shall be treated with rust prevention to ensure the corrosion and fracture caused by the time problem after installation.
During the installation of keel, the position of horizontal keel shall be arranged from bottom to top, and a keel shall be placed 15cm near the ridge. The horizontal keel shall be leveled before welding, and then welded. When installing the bottom of the side panel of the ridge tube tile, a distance of 2cm shall be reserved to install the positive activity between the side bottom plate and the roof tube tile. The small size of the upper edge of the positive activity is 2cm.
Use @ 5 * 20 rivets to rivet the front activities, side plates and roof keel. When installing the ridge, because the size of the inclined activity is non-standard, it needs to be measured on site, cut and made on site, so the size produced on site will be too large, and it needs to be made on site when in use. The actually used ex factory use area will be greater than the actual use area, and the use area shall be increased according to a certain proportion when settling the area.
