How to lock the small door opened by the three-parking flap door of the underground garage?
Today I will share a special garage door case that can challenge the whole network. Generally speaking, the width of the underground parking space is about 8 meters is uncommon, and the installation difficulty of the electric garage door of more than 8 meters span has been great, for this large-span garage door, if you need to install a small door, it is generally recommended to install it on the side and open it separately, so that it will not affect the span of the door panel that is 8-9 meters wide, and will not affect the installation of the stiffener, but the underground garage door installed by the Kunming Haydn garage door recently belongs to the integration of three parking spaces, The owner also requires the door in the door to be opened directly on the flap garage door with a width of nearly 9 meters, which is rare in the case of a large-span door-in-door door, and it is relatively scarce to look at the whole network. What's more, it's even more rare to open the door to the side.
What is the difference between the installation method of stiffeners of more than 8 meters + the door in the middle of the start door + the side of the small door + the stiffener installation method of the large and small doors and the ordinary long-span flap door? The small door is locked separately, the door is separately locked for emergency locks, and the master can truly challenge the most creative, most difficult to install, and extremely explosive flap garage door in the whole network. Do you know how the stiffeners are installed, and how the small door of the long-span door is usually locked to ensure safety? Can you also ensure that the movable door panel will not hit the fixed door head when the door is opened and closed?
