Description
Technical field
The present invention relates to the anti-vibration protected field of cultural relics in the collection of cultural institution, be specifically related to a kind of shockproof bearing of collection showcase.
Background technique
Museum is the window that represents urban history civilization and development overall process, is the indispensable part of Civic Culture Construction.Along with the museum in area, each province and city in succession building up; increasing Movable Cultural Relics are excavated; and concentrated collection protection is among museum; when being convenient to show historical civilization, protecting reparation and daily protection management, also increased the possibility of Movable Cultural Relics extensive damages in the burst fire-disasters such as earthquake.As: China's 512 Wenchuan special violent earthquakes, only shake in latter one month and just receive that peripheral 7 provinces (city) amount to the impaired report of 2766 culturals relics in the collection of cultural institution (292 of rare cultural relics), wherein museum, Wudu, Longnan City house and cultural relics in the collection of cultural institution are impaired particularly serious, amount to 607 historical relics impaired, the rare cultural relics damage reaches 61.Historical experience repeatedly proves: people often just find the artistic true essence of our cordial protection collection after the experience disaster.Roam leisurely in museum, the public wishes to look for consolation, aesthetic feeling and harmony from the cross of space and time of very long historical long river and a gem of art, once and the historical relic damage can't be retrieved.Therefore, the old aseismatic design of the aseismatic design of museum's house structure and cultural relics in the collection of cultural institution and exhibition thereof is particularly important.
China's most cities is all on the strong earthquakes band, and there are larger quakeproof safety hidden danger in museum's house and collection thereof.But seldom, it is shockproof that some museum is forced to adopt fishing line colligation or gluing fixing mode to carry out to historical relic, the impact sight in the museum that really collection showcase and collection is taked to precautions against earthquakes in the timing of exhibition furnishings.China's historical relic is numerous, and the collection of each museum (institute) is ten hundreds of, and even 1,000,000.So, develop real anti-vibration protected effective, the simple structure of cultural relics in the collection of cultural institution, low-cost device and the technical measures of can being widely used in and extremely need badly.
The modes of emplacement in house about collection showcase and showcase, mainly contain the collection showcase and be floated on the house floor and be fixed in two kinds of modes on floor.Shaketalle test research during the different modes of emplacement of collection showcase that had the scholar to carry out, research draws: no matter the collection showcase is in fixing or floatingly put state, and its fundamental frequency is much larger than the seismic waves excellent frequency, so collection showcase earthquake is lighter; For the floating historical relic of putting, hour, under different condition, the response of rocking of historical relic is: the collection showcase floats put>collection showcase rigid condition to seismic wave intensity; When seismic wave intensity is larger, due to the damping by friction effect of collection showcase and vibration table, the response of rocking of historical relic is: the collection showcase floats put<collection showcase rigid condition.For reducing the response of rocking of historical relic, the collection showcase that depth-width ratio is less should be take and floated the form of putting as main, and keeps suitable spacing; Convenient for arranging exhibits, also usually adopt the floating mode of putting of collection showcase.But floating mode of putting the collection showcase is difficult to guarantee issue living horizontal slip, do not rock and do not topple in the rarely occurred earthquake effect.
