Lockside structure of PANIC EXIT DEVICE

PANIC EXIT DEVICE is also called a fire escape lock. As the name suggests, it is a lock that can safely escape at the fire escape safety exit in an emergency. Next, let's take a look at the lock side structure of PANIC EXIT DEVICE.

Here is the content list:

• Lockside structure of the single door

• Lockside structure of the double door

Lockside structure of the single door

The PANIC EXIT DEVICE lock side is a weak point for the fire integrity and vandal resistance of the single door. Under normal circumstances, when designing fire-proof and anti-theft doors, the method of setting reinforcing ribs is adopted to improve the strength of the lock side of the PANIC EXIT DEVICE door leaf, and to improve its ability to resist deformation and damage. The setting of stiffeners should consider the following aspects:

(1) According to the internal structure of the door leaf, design the form of stiffener with good bending resistance that matches the PANIC EXIT DEVICE;

(2) For fireproof and anti-theft doors with high fire resistance time requirements, the specifications and positions of reinforcing ribs should not affect the thermal insulation of the door;

(3) The reinforcing rib on the lock side of the door leaf of PANIC EXIT DEVICE should be connected with the anti-damage reinforcing plate protection box of the lock part to improve the overall strength of the lock side of the door leaf. In addition, since a lock is installed on the lock side of the steel fireproof and anti-theft door, and the lock tongue is used as a limit point, to ensure the reduction of the unit length of the door leaf deformation, the position of the lock should be designed as close as possible to the height direction of the door leaf when conditions permit the middle of.

Lockside structure of the double door

Compared with the single door, when designing the lock side structure of the double door, there is no big difference in the anti-theft performance of the PANIC EXIT DEVICE, but the structural design of the fire resistance is crucial and the most difficult. To avoid the inconsistency in the deformation trend during the fire resistance test caused by the structural difference between the two, the relative matching structure of the movable fan and the fixed fan should be mainly considered when designing the lock side structure of the double door. Considering the matching sequence between the movable fan and the fixed fan in the double door and the direction of thermal deformation, the deformation resistance of the fixed fan should be improved as much as possible when designing the door leaf structure, and the deformation resistance of the movable fan should be similar to or slightly higher than that of the fixed fan. It is lower than the fixed fan to ensure that the deformation of the two is the same. The reasons are as follows:

(1) If the deformation resistance of PANIC EXIT DEVICE is strong, but the fixed fan is weak, the deformation of the fixed fan is greater than the deformation of the movable fan, and the result is that there is an excessive gap in the middle seam of the double door, which causes the loss of integrity.

(2) If the anti-deformation ability of the fixed fan is very strong, the anti-deformation ability of the movable fan is similar to or slightly weaker than that of the fixed fan, and the deformation trend of the two is roughly the same or the deformation trend of the movable fan is larger than that of the fixed fan, then during the deformation process, as the opposite fixed rod, the fan will offset part of the deformation of the movable fan, so that the deformation amount of the two is roughly the same.
