The impact resistance of the double-leaf stainless steel waterproof vault (cultural relics vault) door first comes from the high-strength stainless steel material it uses. This stainless steel has been specially processed to have high hardness and toughness. It can absorb part of the impact force when hit by external force and reduce the damage to the door structure. The solid characteristics of the material itself give the door body the basic conditions to resist impact and it is not easy to be dented or deformed due to slight collisions.
The overall structural design of the double-leaf stainless steel waterproof vault (cultural relics vault) door strengthens the impact resistance. The frame of the double-opening door uses thickened profiles, and the door frame and the door leaf are connected by a precise bite structure to form a stable whole. When it is accidentally hit, the impact force will be evenly shared by the entire frame to avoid damage due to excessive local force. This overall structural design allows the door body to maintain a stable shape when facing impact and reduces the possibility of deformation.
The layout of the reinforcing ribs inside the double-leaf stainless steel waterproof vault (cultural relics vault) door further improves the impact resistance. The reinforcement ribs are distributed inside the door leaf according to the force principle, forming multiple support points and enhancing the rigidity of the door leaf. When the door leaf is hit, the reinforcement ribs can effectively disperse the impact force and prevent the force from being transmitted to the center of the door leaf, thereby protecting the surface of the door leaf from obvious deformation. This internal support structure allows the door leaf to have stronger impact resistance while maintaining a certain weight.
The connection method between the door body and the wall also affects the impact resistance effect. During installation, the door frame will be firmly connected to the steel structure of the wall to form an integral force system. When the door body is hit, part of the impact force will be transmitted to the wall through the door frame, and the load-bearing capacity of the wall will be used to share the force on the door body, reducing the force burden on the door body itself. This close combination with the building structure makes the door body more difficult to be shaken when facing a large impact, maintaining structural stability.
The hinge design of the double-leaf stainless steel waterproof vault (cultural relics vault) door plays an important role in impact resistance. The hinge is made of high-strength alloy material, and the connection with the door leaf and door frame is firm and reliable, and can withstand the torque generated by the door leaf when it is impacted. Even if the door body is hit from the side, the hinge can remain stable without loosening or breaking, ensuring that the door leaf will not be dislocated or deformed due to hinge failure, and maintaining the normal shape of the door body.
The waterproof sealing structure can also play an auxiliary role in impact resistance. The seal on the edge of the door body is not only waterproof, but also has a certain elasticity. It can play a buffering role when it is slightly impacted, reducing the direct damage to the edge of the door body caused by the impact force. Although this buffering effect is limited, it can protect the edge structure of the door body to a certain extent and avoid deformation accumulation caused by frequent slight collisions.
The double-leaf stainless steel waterproof vault (cultural relics vault) door has good impact resistance and can withstand accidental collisions without being easily deformed. High-strength material, stable overall structure, reasonable internal reinforcement rib layout, firm connection with the wall and reliable hinge design together give the door body strong impact resistance. Whether it is a minor collision during daily use or a larger impact in an unexpected situation, the door body can maintain structural stability, ensuring that its protective performance is not affected, and providing reliable safety protection for the items stored inside.
