Introduction to construction technology
- 2. INTRODUCTON TO CONSTRUCTION TECHNOLOGY. • 1.2-THEORY: Construction is one of the branches of civil engineering.it is concerned directly with common people, as everyone wants to have beautiful dwelling building are build from long ago is history, but the difference is of technology as early building were simple and just for purpose of shelter. • So many year ago, people are living in wooden house and cave there is no concept of proper living system. • Concept construction technology starts from 1900. • Before 1900 there is heritage construction • 1900-1949 legacy construction • 1950-1979 conventional construction • 1979-1990 engineering construction • 1990-2002 integrated construction • 2002-2019 composed engineering construction.
- 3. • 1.3-TYPES OF CONSTRUCTION: • There are two types of construction: • Girder tier construction • RCC construction (Reinforced Cement Concrete). • GIRDER CONSTRUCTION: • A girder is a support beam used in construction. It is the main horizontal support of a structure which supports smaller beams. Girders often have an I-beam cross section composed of two load-bearing flanges separated by a stabilizing web, but may also have a box shape, Z shape, or other forms. • In girder tier roof we have load bearing walls and DPC (damp proof course) base.
- 4. • RCC (REINFORCED CEMENT CONCRETE): • RCC column is a vertical structural member which transfers loads from beam and slab directly to the underneath soil. That means an entire building stands on columns. Most of the building failure occurs not only for design fault but also for poor construction practices. Therefore, it is essential to know the construction procedure of RCC column appropriately. • RCC columns are mainly constructed in four different stages, which are • 1. Column Layout Work. • 2. Column Reinforcement Work. • 3. Column Formwork and • 4. Pouring Concrete. • In RCC we don’t have load bearing wall. RCC is used as structural member wherever bending of member is required, like in footing, column, beam, lintel, stairs etc. •
