THE CONSTRUCTION AND FABRICATION OF A METAL BOOKSHEET

CHAPTER ONE

INTRODUCTION

A bookshelf is a device with partitions use for the purpose of self-guarding books and files in offices, libraries and at homes.

A bookshelf can be wooden, metal or glass.  They could also be design in such a way that they could be dismountable or undismountable.  In our project, we decided to design and fabricate on undismountable metallic bookshelf.

Amoung they bookshelves, the undismountable metallic bookshelf has the longest lift span because of its rigidity, quantity of material and it ability to with stand heavy loads.  In other words, the constant loosening and coupling of the component parts which lead to the weakness of the bolt and nut, thus subject the shelf to vibration.

Our project being the undismountable bookshelf was fabricated with variety of material.  The types of materials involved are mild steel square pipes (25mm x 25mm) mild steel sheet metal, metals nets (wire gauze) etc.  in this, the square pipes were used in the fabrication of the frame work while the mild steel sheets were use to cover the partitions and outside bodies of the shelf and the metal nets (wire gauze) where used in the creating of the two doors.

The essence of creating steel fame work with pipes is for it to withstand the stress that will be develop due to the weight of they material and loads or each partition.

In fabrication, the frame was first erected before covering with the mild steel sheet.  The mass and volume of the book to be contained by each partition were considered before they were erected, so certain experiment were carried out which will be discusses in detail in this report.
