Blast doors designed to be installed on entrances/exits or evacuation openings of the shelter to protect the inner space from pressure wave created by blast outside and keep the airtightness of the shelter for CBRN protection. The doors can be equipped with additional splinter protection, penetrating radiation protection, automatic hydraulic mechanisms and additional features according to project specification.
Typically Blast Protective Doors includes the following elements:
-
Door leaf - covers the opening, perceives the force of the blast wave and transfers the blast load to the frame.
-
Door frame - receives the load from the door leaf and transfers it to the enclosing structures (wall or additional frame)
-
Locking mechanism - ensures hermeticity thanks to a special seal and prevents the door from opening under the influence of explosive loads. The hinges are part of the closing mechanism and are also designed to for explosive loads.
