The fire door hinge is a small part of the fire door installation hidden between the door and the frame, but it is an important connection to achieve the opening and closing of the fire door. The biggest advantage of the fire door hinge is that it does not deform in high temperature environments and has a strong structure. When a fire occurs, it opens and closes the fire door properly, ensuring the safety of building personnel's lives. In order to ensure that fire doors are effective in preventing fires, we need to understand how to install fire door hinges to make fire doors work.
Below we understand the installation of fire hinges from these aspects:
1. Preparations for installing fire door hinges
2. How to install fire prevention hinges and precautions
1. Preparations for installing fire door hinges
1-1. Fire hinges should be sized to match the door before installation. If the height, width and thickness of the fire hinges do not match, the load on the hinges may not meet the requirements and will affect the future use and function of the fire door.
1-2. The installation of fire door hinges requires matching accessories, such as supporting screws. It is also necessary to check that the fittings match and that the number of screws is complete. In addition to this, the position and number of hinges to be installed to match the door should be determined.
1-3. Check the verticality of the inside and outside facades, the verticality of the left and right facades, and the horizontal height of the fire door frame with a level ruler before installation. If the door frame has a small deviation in any direction, it must be taken into account when installing the door leaf.
1-4. The number of door hinges is determined according to the weight, size and material of the door. The reasonable configuration can bear the weight of the fire door, avoiding deformation and damage due to long use. Fire prevention hinges need to be properly planned to avoid uneven force.
2. How to install fire prevention hinges and precautions
2-1. Slotting. After determining the position of the fire door hinge installation, you need to make a groove on the side where the hinge is installed. The depth of the groove must be the same as the thickness of the sheet. The sheet is laid flat in the groove, and the surface of the sheet is checked to be flush with the surface of the door cover.
Pay attraction: The width of the slot is about 2mm less than the width of the single-piece hinge to prevent them from rubbing against the door frame.
2-2. Fire rated hinge screws must be tightened. During the process of tightening the hinge, it is necessary to fix the hinge with supporting screws. The screws should be perpendicular to the door cover and the edge of the door. If the screws are inclined, the hinge will be squeezed when the door is closed. The door will shorten the service life of the hinge, and will affect the function of the fire door, which may cause the fire door to lose its fire function.
Installing the fire hinges does not mean the end. It is also necessary to check the function of the hinges: check that the hinges are flexible in opening and closing, and also check that the fire door hinges are smoothly connected to the door frame and that the installation must be perfect.D and D HARDWARE's fire door hinges are made of SUS201/SUS304/SUS316 and meet UL and CE testing requirements and still work properly to open and close fire doors.
