The vault door of Henan Art Museum

Most art museums store valuable items, so how are these valuable items protected? In the past, most cultural relics and antiques were stored in safes, but some drawbacks have emerged. For example, some large cultural relics cannot be stored in safes, and managing large quantities of safes is also quite troublesome. Therefore, many art museums have started to use safes nowHenanArt museum vault doorThe vault door of the art museum not only has higher protection performance, but also has larger storage space.

The vault door of Henan Art MuseumPerformance standards:

The locked vault door has a wheel handle that is not loose, and the concavity and convexity of the front of the door body and the front of the door frame are strictly controlled within1-1.5mmThe gap between the front perimeter of the door frame and the door leaf should not exceed1mmAnd it is not possible to directly view the inside of the warehouse through this gap. The surface of the door frame and leaf should be smooth, and the flatness of the outer surface should not exceed2mmThe flatness of the inner surface is not greater than4mmThe steel bars extending from the door frame of the vault and the wall are firmly welded, and the welding points on each side of the left and right sides are not less than6One, the upper box should not be less than3Ensure that the door frame is perpendicular to the horizontal plane, and after welding, fill the gap between the door frame and the wall with cement mortar.

The panel of the vault door is made of imported stainless steel plate, and the vault door achieves vertical balance. The vault door can be positioned at any position without self covering phenomenon. The surface of the stainless steel decorative panel is straight, with good glossiness, no protrusions, depressions, scratches, and no right welding scars at the welding points. The coating layer does not bubble, crack, or wrinkle, and the surrounding gaps are balanced. The vertical position is aligned, and there is no noise when opening or closing the door.

The kumen hinge is made as an external joint with two sets of flat bearings inside, designed to be lightweight and flexible. In addition to supporting the entire weight of the door leaf, it can also be adjusted up and down within a range of no more than80NUnder the external force, the door leaf can be flexibly started and closed, and can effectively prevent the door from falling and deforming due to its own weight. The door tongue and actuator move flexibly, and the manual hidden switch is not subjected to more than30NUnder the action of force, the door can be locked or opened, ensuring that one person can open and close freely.

All components of the vault door are equipped with anti-corrosion measures (including spraying, electroplating, plastic spraying or other effective measures), which can ensure normal use during the service life of the main building of the warehouse.

When different metals are used in combination, they do not cause electrical corrosion.

The vault door of Henan Art MuseumInspection criteria:

1.Appearance and structure: All steel components should undergo electroplating, painting, or other anti-corrosion treatments on their surfaces. The basic structure includes door frame, door leaf, daily gate, mechanical password lock, lock and lock actuator. According to usage needs, time lock, anti-theft electronic lock, safety re locking device, alarm signal transmission device, etc. can be set.

2.Measurement of frame and leaf dimensions: The gap between the door frame and the front edge of the door leaf should not exceed1mmIt should not be possible to directly peek into the gaps inside the door. The screen degree of the outer surface of the door frame and door leaf shall not exceed2mmThe flatness of the inner surface is not greater than4mm.

3.Inspection of welding points connected to the wall: The welding points on the left and right sides of the vault door shall not be less than6Point, the upper box should not be less than3Point.

4.Flexibility: In addition to supporting the weight of the door leaf, the door hinge should also be adjustable. Not greater than80NUnder the external force, the door leaf can open and close flexibly. The door tongue and actuator should be flexibly used, and the manual concealed switch should not be subjected to more than30NUnder the action of force, the door leaf can be locked or opened.
