CONSTRUCTION OF BOOK SHELVE
A book shelve is a structure which here series of compartments for the preservation of books, valuable or useful materials, which are made up of metal, wood or plastic materials of construction. (Engineering materials).
The book shelve was constructed in the institute. (I.M.T Enugu).
However, before the construction, two standard metal sheets of length 96 inches and height 48 inches respectively, where dimension and divided into these required dimensions and sizes. Then welding operation were carried out and the dimension parts was welded into their fit places.
More so, filling of operation was also carried out, in other to smooth surface of the construction work and filling of pores and holes created was done.
Finally, in other to avoid destruction and corrosion or chemical attacks painting operation was done which the last operation was carried out.
Furthermore, the major result obtained from the construction were up to standard of a recommended book shelve. The cost for labour, purchasement, transportation, machine, and general total cost was N24,000.00 only (Twenty four thousand Naria only).
A book shelve is a set of shelves with doors either built into a room offices or industries as a fixed, or a separate piece of furniture, used for utensils, provisions, clothing, storing, book shelves etc. those cupboard used in the libraries and offices for packing books are called book shelves.
In the industries, materials are stored in cupboard refer as a facility for storage.
In material selection for the construction of any cupboard strongly depends on the properties and purposes the cupboard will serve. Generally, considering all the materials of construction, it can be seen that, for instance, both metals and non- metals have their individual merits. But in companism, metals have a lot of advantages over non.metals.
For instance, while many types of metal are suitable for high temperature operation, non.metals such as wood and glass are suitable for lower and limited range of temperatures. Metals posses a wider range of chemical stability them non.metals. So, it can be said that the obvious advantage of first cost cheapness of non.metallic materials is counseled by other disadvantages of non.metals, the most glaring of which is that of narrow applicability. Considering the cost also, the first cost of materials is even not takes as a sufficient indicator on which to base the selection of construction materials. The following cost factors among other must also be considered. Fabrication cost, installation cost, maintenance cost and cost of replacement. These cost factors must be considered in the material selection for construction.
Books shelve desire it name and purpose sometimes from the material of construction and also the shape it takes. Most book shelves built in homes, usually used for lairing clothes, serves the purposed of protecting clothes for the dust and other things and so, they are arranged in a chronological order, files are also arranged in arc inside the book shelve for protection of the necessary documents of the institution. Such cupboards are normally refers to as bookshelves. It is usually made of metals.
Most cupboards used for domestic purposes such as keeping of dishes and provisions, are usually made of wood, and in this case, there is no observation of all the operation involved in the construction of metal cupboard.
This is because of the soft nature of wood.
Instead of the use of guillotine saw is used in the cutting off, of the excess of use of the wood during constmction.instead the use of welding, nail is used in the arrangement of the different parts of cupboard. Another major different between those cupboard made of wood and those made of metal is that, wooden cupboard cannot protect the trough inside it in presence of fire outbreak without getting burnt
There are several types of metals that can be used for construction. Metals for contraction include: Gold, Silver, Aluminum, Bronze, Steel, and Iron. There are usually about three types of steel, as it constitutes the widest use metal. These types include low carbon-steel that has about 0.3%-0.4% carbon contain about 0.3%-0.6% carbon, and high carbon steel that contain about 0.7%-20%carbon.
Steel are used in the construction of metal cupboard, this is because it is soft to cutting, bending and several operation applied to the metal during construction. The galvanized type of steel has a nature of stainless steel and so does not support rust.
Because of this, it is not painted after using it for construction. In fabrication of sheets of metals, several types of gauge are produced and these include, gauge 22, gauge 20, gauge18, gauge16, gauge14, gauge12 and gauge10.
G auge18 and gauge16 are the best types of metal bookshelves
