Construction
of a steel cupboard
ABSTRACT
This project work was
constructed to enable students of chemical engineering to learn how to carry
out construction works. This was done to acquire knowledge about metal
properties and its fabrication. It was also constructed to observe the various
measures and operations carried out in the construction of a standard steel
cupboard.
The construction was
done using some equipment and tools to enhance the construction
procedures. The equipment are electric arc welding machine, guiltine,
spraying machine and some tools like centre punch, hammer, hand saw and
scriber.
Steps were taken to
produce the dimensions of the cupboard on the metal sheet. The dimensions
of the different parts of the cupboard were marked and cut out as follows:
Door
- 1ft 7 ¾ “
x 2ft 4 ¾ “
Back - 3ft 3 ½
“
x 3ft ¾ “
Base - 1ft 6 ½
“
x 3ft 3 ½ “
Body -
3ft 5 ½
“
x 3ft 6” x 1ft 8 ½ “
Partition-
1ft 2 ¼ “
x 3ft ½ “ x 1ft 6 ½ “
These parts of the
cupboard were welded to the body frame of the cupboard which was constructed
with squire steel pipes. The welding procedure was electric arc welding
with gauge 10 electrode. The cupboard was then filed, cleaned and was
painted to have a good finishing.
Precautions were
taken during this construction toward errors during measurements and to ensure
safety during the operations. This helped us to produce a standard steel
cupboard of high corrosion and chemical resistances which is also free from
attack of temites.
The total cost of
producing the cupboard is N12,700.00 which includes the cost of materials,
labour cost and cost of transportation.

CHAPTER ONE
INTRODUCTION
Since human wants are
practically unlimited and the resources for satisfaction are unlimited in
supply, for this reasons, the creation of storage structure was initiated to
preserve the available resources. Thus the storage structure is the
cupboard.
A cupboard is a set
of shelves with 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, kitchen cupboard, linen cupboard, laboratory cupboard and so
on. The general use of cupboard is for spring materials in the
laboratory, homes, offices, kitchen. These are used to store items like
food, books, cloths, files, dishes, audio and video cassettes etc.
Cupboard can be constructed with materials like wood, steel and some other
kinds of metals.
However, steel as a
material of construction of this project has more advantage over wood.
Steel is not attacked by termites or insects and lasts longer than wood.
The steel cupboard is usually rectangular, square in shape and cannot be broken
like wood cupboard. This makes the materials kept inside very preserved
and safe. Though metals commode as a result of presence pf air, moisture
and chemical, the corrosion can be prevented by painting and coating it.
In construction of a
stall cupboard many factors are considered such as availability of the material
of construction, its durability and quality. Wide ranging research work
is carried out to obtain the best possible design with the desired type of
structural material for the cupboard being put to use. This is because
there are varieties of materials that could be used for construction.
Such varieties of materials are cast iron, wrought iron, low carbon steel, mild
steel aluminum and aluminum alloy. The classes of construction materials
apart from wood has a very high range of advantages as they are stronger and
more machinable. They also have properties like thermal and electrical
conductivity, high tensile strength, reflectibility and ductility.
Moreover, mild steel
is usually most suitable for fabrication processes that involve cutting,
bending, folding and other operations. This is because it is easily
machined and can be handled without risk of wear and tear. The cost was
also considered so much because it involves the quality of materials both in
design and construction. It is possible to produce a quality steel
cupboard with reduced cost.
Finally, the steel
cupboard has wide ranging application and importance. It is necessary in
the preservation and storage of documents, equipment, chemical species and
laboratory equipment.
