ABSTRACT
A workshop cupboard is a
facility designed from mild steel for the storage of various materials, like
book material and non-book materials e.g. workshop tools, labouratory wares and
reagents, etc; after operations in a chemical labouratory, mechanical workshop,
or else where.
The construction of a workshop
cupboard requires the consideration of lots of characteristics of the
materials, which are used for the construction, such as physical and
mechanical; chemical properties, service requirements, its fabrication process
as well as cost of production.
For the constructional project, every
necessary technical knowledge was employed; ranging from selection of
engineering materials, to constructional procedures which includes sketching,
drawing to scale, marking out, cutting, sand preparing, bending and folding,
welding and painting, all geared towards the achievement of the construction of
a steel cupboard.
In the constructional project, mild
steel was chosen as the material of construction not because of its corrosion
resistance, but for such properties as cost, strength and ease of fabrication.

CHAPTER ONE
1.0 INTRODUCTION
A cupboard is a set of
shelves with a door or doors in front either built into the wall of a room or
as a separate piece of furniture, there are so many kinds of cupboard such as
office cupboard, labouratory cupboard kitchen cupboard, linen cupboard, etc.
Cupboard is generally used for storing
materials in the labouratory, offices, kitchen and homes such as books,
foodstuffs, cloths, files, dishes, audio and video cassettes, glassware,
chemical reagents, etc. cupboard can be made with different types of materials
such as steel, wood, glass, and some other kinds of metals.
In the constructional project, steel
as a material of construction has a lot of advantages over wood. It is not
attacked by termites or insect and lasts longer (i.e. are durable) than that of
wood that is commonly used. Steel cupboard is usually a rectangular piece of
steel fabricated for the purpose of storage. Since steel cupboard cannot be
broken. Since steel cupboard, then the material kept inside it is preserved.
Though metals are known to corrode of which the primary causative agents are
air, moisture and some chemicals but when the cupboard is not exposed to
moisture by adopting preventive measure like organic coating (i.e. painting) to
increase its resistance to corrosion.
During the construction of the
cupboard, the research considerations were the material availability, its
durability, quality affordability and the maintenance and replacement of the
parts of the cupboard or the shelf. Hence, a research was carried out on the
Engineering property of the material of construction. Steel used for the
construction is environmental friendly, hazardous and resistant to insect
attacks. This is the area in which the cost of production was made, by adopting
some amendment with the aim to achieve the steel cupboard; in such a way that
it becomes a modern steel cupboard of a standard size which can contain quite
some number of materials like books, files and some labouratory materials.
The research was done also, so as to
obtain the greatest design with the desired structural material for the
cupboard to maintain its quality for a long period of time without having any
fault or damage, hence, it is important to produce facility hence, it is last
longer and the quality been of a great importance in the construction of the
steel cupboard.
The various parts were arranged and
shaped, connected in such a way that it will provide an efficient and
economical solution to the construction problems. The cost was also considered
so much because the cost usually involves quality of the material. But in
designs and construction, it is possible to produce a quality steel cupboard
with reduced or less cost. And the labour cost of fabricating the material was
involved too, during the construction. The steel cupboard was fixed with
rollers stands and stoppers for stability at any point it is kept and for easy
mobility, which was solidly welded. All these factors were taken into consideration
so as to produce a quality and durable steel cupboard that is affordable. The
cupboard was constructed to the test of maintenance and durability.
