Description

Detachable bracket system for cultural relics and method of making the same

technical field

The invention relates to the technical field of cultural relic protection, in particular to a detachable bracket system for cultural relics and a manufacturing method thereof.

Background technique

In the museum exhibition industry, there is a problem that theoretical research is far ahead of practice, the technical research on display equipment is not sufficient, and there are few similar technologies for reference. Existing methods mainly include: (1) Use plastic materials (such as blue butyl rubber) to paste and fix cultural relics on the booth; (2) Customize mass-produced buckles, which are inserted into the back panel of the showcase or fixed to the back panel of the showcase with screws , fix the cultural relic fragments; (3) custom-made the cultural relic fragment bracket, put the cultural relic fragment on the bracket; (4) use the adhesive to bond the cultural relic fragment in the showcase.

For the above existing method (1), the plastic material cannot provide comprehensive support and protection for the cultural relics. Due to the limited viscosity of the blue-butadiene adhesive, if the cultural relic fragments need to be vertically fixed on the back plate, the blue-butadiene adhesive may not be fixed firmly, which may cause cultural relic fragments. In addition, the use of blue butyl rubber to fix cultural relics will also affect the appearance and affect the exhibition and display effect of cultural relic fragments. For the above method (2), whether the snaps produced in batches are inserted into the back panel of the showcase or connected to the back panel with screws, holes need to be drilled in the back panel of the showcase, which destroys the integrity of the showcase and causes subsequent maintenance difficulties and increased maintenance costs. Moreover, this kind of buckle forms a relatively large pressure on the fragments of the cultural relics, which may further damage the edges of the fragments of cultural relics due to uneven force. For the above method (3), the cultural relic fragments are directly placed on the supports produced in batches. Since the shape of the support cannot match the shape of the cultural relic fragments, on the one hand, the cultural relics partially contact the support, resulting in uneven force and affecting the safety of the cultural relic fragments. On the other hand, the exposed support structure of the bracket will also affect the appearance and the display effect. For method (4), it is the most simple and most serious treatment method. Although the adhesive is solidified and firmly bonded, it can fix the cultural relic fragments well, but the adhesive is not easy to separate from the cultural relics, which makes the cultural relic fragments The fixation is completely irreversible, so that the fragments of cultural relics cannot be easily dismantled from the showcase, and that the fragments of cultural relics cannot be restored to their original state before being fixed. Cultural relic protection requirements in the exhibition.

To sum up, the existing bracket design of cultural relic fragments has disadvantages such as poor compatibility (poor adaptability to changing display environments), poor concealment, and poor safety. Under different display environments and display methods, the fragments of cultural relics need to be reworked repeatedly, which increases the probability of damage to the cultural relics, but it is still difficult to achieve a good display effect, and it also greatly reduces work efficiency and wastes resources. .
