Design and fabrication of a hollow finn builder mould

Abstract

This project presents the design and Fabrication of hollow Finn Building machine which will be used for construction of hollow concrete wall structures. The aim of this project is to fabricate hollow Finn Builder mould. Finn Builder is an innovative building technique which is used for construction of concrete wall structures. The technology involves the use of building mould made up of rigid material mild steel. The advantages of Finn builder walling technology are Versatility of the mould to build different types of concrete structures, time Efficiency due to prefabricated nature of mould allowing assembling and disassembling easily, cost effectiveness of the mould due to reusable nature of the mould reducing frequent purchase, less labour is required to operate the mould, durable and low maintenance costs. The existing Finn Builder mould lacks design provision for hollow wall concrete construction. The creation of holes in wall of a structure has advantages of reducing the weight of structure leading to reduced load on foundation, reduced material usage (concrete) due to holes which reduce the amount of concrete used for building hence reducing construction costs. The contribution of this project is to reduce the weight of structure which reduce foundation requirements and reduce material usage which leads to reduced construction costs. Fabrication of Finn builder mould components and test performance of the mould was also covered. The test results of concrete are also presented in this report (the slump test and compressive strength tests). Key words: Finn Builder, Fabrication, Innovated, simulation and rigid material
