Description

Vertical circulation drawing arranges combined bay
Technical field
The present invention relates to a kind of vertical circulation drawing and arrange combined bay.
Background technology
Engineering drawing is a kind of blue drawing used in engineering, and the general mode of folded alignment that adopts is bound, and have front cover still without ridge, and the drawing amount that different engineering possesses is different, causes drawing to bind this thin and thick and differs.Current drawing is deposited, and mostly adopts drawing cabinet, multi-layer drawers established by cupboard, be placed in one deck by drawing by engineering reactor, during use, drawing is ransackd in drawer pull-out, drawing scheme deposited by existing layering drawer, being stacked by engineering by drawing, there is following problem in this location mode:
1, be unfavorable for searching drawing.Because this drawing single is without ridge, all drawing informations are all imprinted on drawing homepage, when needing certain this drawing, must ransack each layer drawer in turn, lose time.
2, effectively space can not be utilized.According to the difference of project content, the drawing thickness designed by every engineering, volumes are all not quite similar, thus drawing more thicker time, may need to take whole one deck drawer; Drawing less thinner time, for preventing also needing to take one deck drawer in a jumble.This disposing way, certainly will cause the waste in space.
3, drawing is put easily mixed and disorderly.Due to the bookbinding particularity of drawing, most of drawing is all the thick pattern of thin, the non-binding side of binding side.When many drawings pile up together, be easy to, in the process of push-and-pull drawer, more easily topple over, and then cause drawing mutually to adulterate; Meanwhile, because different engineering drawing thin and thick differs, and the thickness of drawer is certain, therefore the drawer space that different engineering drawing takies is also different.Repeatedly taking in the process of drawing, very easily causing drawing mixed and disorderly.
Summary of the invention
For the drawing existing for above-mentioned existing engineering blueprint drawing location mode arrangement, deposit and search very inconvenience etc. problem.The invention provides a kind of vertical circulation drawing and arrange combined bay, this combined bay changes the location mode of existing drawing, drawing is put more neat, searches more convenient, improve space efficiency utilization simultaneously.
