The safety of doors and windows is the first line of defense for home protection. It can effectively prevent violent door breaking, which not only protects property interests, but also ensures the safety of your family. Modern door lock technology and security systems have been able to greatly improve the door's resistance to damage, but it must be systematically configured based on the door structure, installation process, and security requirements. Next, we will analyze how to build a reliable portal protection system from six key dimensions.
How to choose an anti-pry door lock
The key to anti-pry door locks lies in the grade of the lock cylinder and the structure of the lock body. It is recommended to choose a C-grade lock cylinder. Its anti-pry technology can open for several hours. The key shape is complex and has patent protection. The lock body should be preferably a model with a solid structure and an anti-pry steel sheet. When there is an external force to pry, the steel sheet will jam the door frame, effectively delaying the progress of damage.
When performing installation operations, pay attention to the matching gap between the lock bolt and the door frame. Under ideal conditions, the gap should be less than 1 mm. It is recommended to use anti-collision hooks. When the lock tongue pops up, the upper and lower steel bars will be embedded into the door frame simultaneously. After installation, you can use a dynamometer to test the load-bearing condition of the lock point. For ordinary doors, the load-bearing capacity should be more than 500 Newtons, while for entrance doors, it needs to be more than 800 Newtons.
How to strengthen door frames more effectively
The key points of door frame reinforcement are: one is to strengthen the anchorage, and the other is to replace the component materials that have a strengthening effect. The traditional wooden door frame can be replaced with a stainless steel frame, which is 2 mm thick and filled with epoxy resin glue to increase toughness. The bolts used for anchoring should be made of expanded stainless steel, and their length should not be less than 10 centimeters. Each door frame must be equipped with at least 6 anchoring points.
For concrete walls, it is recommended to use chemical anchors to fix door frames, whose bonding strength is more than three times higher than mechanical anchors. During installation, it is necessary to add an L-shaped anti-collision iron on the inside of the door frame so that the impact force can be dispersed to the wall. After completion, hydraulic clamps can be used for testing. A qualified door frame should be able to withstand an impact of 2,000 Newtons without deformation.
Which type of security door is safer?
A high-quality anti-theft door must have a test report indicating the anti-vandal time limit. A Class A anti-theft door requires that it cannot be opened by force within 30 minutes. The thickness of the door body steel plate must reach 1.2 mm for the front plate and 1.0 mm for the back plate. The internal filler should be polyurethane foam material instead of ordinary honeycomb paper.
It is recommended to choose items with multiple certification marks, such as GA certification from the Ministry of Public Security, CE certification from the European Union, etc. The door structure tends to adopt an interlocking design, and the overlap between the door leaf and the frame is not less than 12 mm. Pay special attention to hinge side protection, which should be equipped with hidden hinges and anti-tamper pins.
How to prevent electronic access control from vandalism
Modern electronic access control should have anti-tamper alarms and backup power functions. For this, it is recommended to use a card reader with a stainless steel housing, whose protection level must reach IP65 or above. The controller is best installed in a concealed location within 5 meters of the door, and the lines need to be protected by galvanized steel pipes.
In terms of power outage protection, the system should be equipped with a UPS power supply lasting more than 12 hours, and it should have the function of supporting emergency opening of a mechanical key. For important areas, a vibration sensor can be installed. When this sensor detects an abnormal impact, it will trigger a 110-decibel on-site alarm and automatically push alarm information to the bound mobile phone.
What details should you pay attention to when installing?
When installing the door, it is necessary to ensure that it can be reliably connected to the wall. When carrying out measurement work, the verticality of the door opening should be carefully checked. The deviation must not exceed 3 mm. When installing the base frame, you need to use anti-rust materials. Anti-corrosion galvanized square steel needs to be injected with high-grade cement mortar at the connection point with the wall. After the door leaf is installed, the compression amount of the sealing strip needs to be debugged to ensure that the compression amount can reach 25% to 30% when the door is closed. .
When installing the hardware device, special attention should be paid to its directionality and symmetry. The hinges should be of the pressure bearing type. Each hinge should be fixed with at least 4 stainless steel screws. After the installation is completed, multiple opening and closing tests need to be carried out to ensure that the door leaf can still lock normally even when subjected to a thrust of 200 Newtons.
How to do daily maintenance
Check every week to see if the door leaves open and close smoothly, and see if there are any cracks in the sealing strips. Use graphite powder to maintain the locks every month, and it is forbidden to use lubricating oil. Check door frame anchor points every quarter for looseness, and use a torque wrench to test bolt tightness.
If you notice that the door leaf is sagging and the sagging amplitude exceeds 2 mm, the hinges should be adjusted in time. Electronic access control must conduct a power outage test every month to check whether the backup power switching is in a normal state. Before going out for a long time, you should use a vernier caliper to measure the change in door gap width. Once it exceeds 1.5 times the width during installation, professional maintenance is required. Provide global procurement services for weak current intelligent products!
After achieving the above protective measures, it is recommended to conduct safety drills regularly. Has your home had a complete access control system inspection in the past six months?
