Methods and Types of Precast Construction

September 5th, 2011

Methods and types of precast construction are:

1. Assembled per element

2. Lift – Slab system

Lift – Slab floor system is the binding element to the column by using a hydraulic jack.

The principle of this construction is as follows:

The floor is using concrete slab, who casted on the ground floor
Column is a vertical load can be as a supplier of precast elements or cast in place.
After the floor is strong enough can be removed one by one with a hydraulic jack.

3. Slip – Form System

In this system, concrete is poured on a steel mold that can move on following the addition of climbing the wall height is concerned.

4. Push – Up / Jack – Block System

In this system, the top floor roof casted at the first and then lifted up with hydraulic – jack mounted below the vertical supporting elements.

5. Box System

Construction using dimensional form of concrete cube modules.

Precast Concrete Systems and Development Issues

August 1st, 2011

In the structures of construction with concrete materials, known as 3 common development methods, i.e. the Conventional System, Formwork System and Precast Systems.

Conventional system is a method that uses traditional materials of wood and plywood as formwork and scaffolding. Formwork system has moved one step forward from the conventional system with use of system formwork and scaffolding of metal material.

Formwork system is divided into two, namely Outinord System and Mivan System. Outinord system using steel materials while the Mivan System using aluminum materials.

In the precast system, all components of buildings can be fabricated and installed in place were built. The process of making components can be done with good quality control.

Precast System Development Issues

There are three major problems in the development of the precast system:

Reliability of connections between components.
The absence of specific planning guidelines for precast structural system.
Cooperation with the planners, in other related fields, especially with the architecture and mechanical.

The Principle and General Description of Prefabricated Construction

July 3rd, 2011

Industrialization in building construction is a natural progression as well as has happened in other industries. Actually slower than the others because it faced greater obstacles in the building industry, which not only are fashionable trends (the latest fashion trend), but also deals with the statement that demands value: Changes in mental attitude and thoughts of some experts.

The Path to Building Industrialization

So far, people feel attached to the house that should be valued individually, then of course people will feel something else when suddenly residential accommodation:
Provided in the form of blocks or flats that are not building as usual.
Buildings are not designed specifically as an individual user requests.
Building was established in the form of products that have been completed without any more intervention from the user the opportunity.
Building on the design with a performance similar or even equal.
The building is directly so if you want to design and build individually.
With a very limited choice.

How to Developed Industrialization?

The building industry should also make progress; use of cranes and other machines but with a broader way. Backwardness in the building industry developed with an automated way of industrialization in the entire process from the preparation and manufacture, casting, concreting (foundry), prestressing, storage, transportation (freight), erection (establishment), lifting (removal) and handling.
