If you perform construction industrial bookcases and shelves, you will notice that their depth is normally twice the width of the book. So the books have to put in two rows, and it is very uncomfortable, otherwise much unused space remains. To make the Cabinet more narrow, it is impossible — it is unstable. The way out is to provide access to books from several sides, and the wardrobe to put an end to the wall. This principle was the basis for the proposed column for books.
The Cabinet is symmetrical about its longitudinal plane. The selected height of the shelves 265 mm (for most books) and 325 mm (under publishing big formats), depth — 227 mm (sawn along the plate width 460 mm). Connection plate — wooden nageljami on glue casein or PVA. Epoxy glue to use is undesirable, as the plates can be stained and traces of stains. Special attention should be given to the thoroughness of the partitioning plates and holes for the pins — this will determine the labour costs of Assembly and its quality. With success it is possible to apply the compound on the screws in the places where their heads will not be visible. For protection of the chipboard from the bundle with connection screws in the plates must be drilled the necessary holes.
