Diseño y construcción de una cortadora de cilindros de hormigón para el laboratorio de la Carrera de Ingeniería Civil de la Universidad Técnica de Ambato.

Abstract

This technical project deals with the design and construction of a concrete cylinder cutting machine for the laboratory of the Civil Engineering Department of the Technical University of Ambato. This project was carried out taking into account the lack of a machine that is static in the first instance because cutting with manual machines presents a high risk of accidents. This equipment is designed as static in order to reduce accidents associated with the use of manual tools and to improve cutting accuracy, a crucial factor for quality testing of concrete specimens. The development of this project was based on previous research, ergonomic analysis, technical standards as well as ASTM C39 for design and functionality verification, among these are main features such as perpendicularity and flatness, highlighting the use of diamond disc of special diameter for cutting cores of 16 cm, 3Hp low speed electric motor and a robust structure of ASTM A36 steel with an anticorrosive coating, prioritizing the ergonomic design of the table ensuring user comfort at the time of use. It included the selection of materials, CAD software assisted design and performance simulations in terms of stresses and behaviors of critical elements, as well as welding joints to ensure a better result at the time of construction, functionality and efficiency improving the quality of cutting and optimization in the time of this, minimizing the risk of students.
