A fire protection securing apparatus for securing a door actuator includes a retaining plate, designed for being secured to an assembly surface, in particular door, frame or wall, wherein, perpendicular to the retaining plate, an assembly axis is defined. The fire protection securing apparatus further includes an assembly plate which is secured to the retaining plate and which is designed for receiving the door actuator, and at least one closed reaction chamber arranged between the retaining plate and the assembly plate. The apparatus also includes a drive element of thermally intumescent material which is arranged in the reaction chamber and which is designed to push the assembly plate away from the retaining plate upon thermal activation.
A fire protection securing apparatus for securing a door actuator, the fire protection securing apparatus comprising:
An arrangement comprising a door actuator and a fire protection securing apparatus comprising a retaining plate configured for being secured to an assembly surface, wherein, perpendicular to the retaining plate, an assembly axis is defined, an assembly plate which is secured to the retaining plate configured for receiving the door actuator, a closed reaction chamber arranged between retaining plate and assembly plate, and a drive element of thermally intumescent material, which is arranged in the closed reaction chamber and which is configured to push the assembly plate away from the retaining plate upon thermal activation, wherein the drive element comprises only the thermally intumescent material, and only the thermally intumescent material is arranged in the closed reaction chamber, wherein the door actuator is configured to be arranged on the assembly plate.
