Abstract

The invention discloses a back-mounted integrated tunnel protection door frame framework, a door frame and a mounting method. The back-mounted integrated tunnel protection door frame framework comprises a steel bar framework, pouring filler and a concave table frame. The steel bar framework is fixedly arranged on the concave table frame. The concave table frame is used for forming the protection door frame framework, and the pouring filler is poured in the concave table frame. The mounting method is used for mounting the protection door frame. The steel bar framework serves as the protection door frame framework, stress can be enhanced, and the anti-bending performance and anti-deformation performance of the protection door frame are improved; the concave table frame cooperates with the protection door frame, and the protection door frame and a protection door are effectively sealed; the pouring filler is adopted by the protection door frame, fireproofness and sealing performance of the protection door can be improved, and the overall fireproof requirement can be met; and meanwhile, the situation that the protection door loosens, topples over and even is separated under the condition of lone-time piston air is avoided, and use safety of the protection door is guaranteed.

Description

technical field [0001] The invention relates to the field of tunnel protective doors, in particular to a post-mounted integrated tunnel protective door frame frame, door frame and installation method. Background technique [0002] With the vigorous development of my country's high-speed railway construction, the "Code for Fire Protection of Railway Engineering Design" and "Code for Design of Railway Tunnel Disaster Prevention, Evacuation and Rescue Engineering" have also been updated and revised in time. The norms have more and more stringent requirements for equipment cave protective doors and evacuation protective doors. Protective doors must be perfect for protecting cavern equipment, ensuring unimpeded information, crowd evacuation and creating escape conditions. [0003] In the prior art, the installation of the tunnel protection door is mainly connected to the wall through three methods: pre-embedded steel plate, planted reinforcement or post-installed chemical anchor...
