Process of Production And Transportation of Prefabrication

SYSTEM PRODUCTION

The term systems production describes a series of operations directly involved in the manufacturing process or more application of prefabricated molding units, there are many techniques since almost all types of prefabricated products require a specific series of operation in their production.
However, these techniques can be grouped into three basic production methods.

These are,
  • The support system
  • The conveyor system
  • The aggregate system
  • Support system
In the support system, the prefabricated nature at the point where they were molded. While the production team moves to successive are the bed in which they are prefabricated.
process of production and transportation of prefabrication

Conveyer belt

  • The production system of the conveyor belt divides the entire production process into a series of operations carried out at a successive and permanent separate point for heat, it can be by means of conveyor belts and crane, etc.

Aggregate system

  • The word aggregates describe a large and complex set of permanently installed machines and A mechanical application that can carry out most of the separate operations involved in the smelting of concrete components.

PRODUCTION

  • The location of prefabricated yards consists of storage facilities suitable for transportation and assembly equipment and the availability of raw materials are the critical factors that should be carefully planned and provided for the effective and economical use of precast concrete components in a building.
  • The manufacturing of the components can be done in a factory located centrally in a site where prefabricated yards are installed at or near the job site.

FACTORY PREFABRICATION

The prefabrication of the factory is restored in a central plant for the manufacture of standardized products.
  • It is a capital intensive production where the work is carried out throughout the year, preferably under a covered shed to avoid the effects of seasonal variations, the high level of mechanization can it will always be introduced in this system where work can be organized similarly to a factory with help from the constant team of workers.
  • The basic disadvantage in the prefabricated factory is the additional cost in the transportation of elements from the plant to the workplace, sometimes the shape and size of the prefabricated must be limited due to lack of adequate transport equipment road controls, etc.

PREFABRICATION OF THE SITE

  • In this scheme, the components are manufactured at the site near the worksite as possible. This system
  • It is usually adopted for a specific work order for a short period. The work is usually done in open space with a valuable local workforce. The equipment, machinery, and molds are mobility.
  • Therefore, there is a defined economy with respect to the cost of transportation. This system suffers from the basic inconvenience of its failure to adapt to any high degree of mechanization. It has no elaborate Quality control arrangements.

FABRICATION PROCESS

The various processes involved in the manufacture of prefabricated elements are classified as follows:
  • Main process
  • Secondary process
  • Subsidiary process

MAIN PROCESS:

  • It involves the following steps,
  • Provide and assemble the molds, placing the reinforcement cage in position for reinforced concrete works
  • Fixation of inserts and tubes when necessary.
  • Deposit the concrete in the molds.
  • Vibrate the concrete deposited in the molds.
  • Moldings of the forms.
  • Healing
  • Stacking of prefabricated products.

SECONDARY PROCESS:

  • This process is necessary to successfully complete the process covered by the main process.
  • Mixing or manufacturing fresh concrete.
  • Prefabrication of reinforcement cage
  • Manufacture of inserts and other finishing elements to incorporate in the main prefabricated products.
  • Finishing of prefabricated products.
  • Test prefabricated products.

TRANSPORT

  • The transport of the prefabrication elements must be carried out and with extreme care to avoid any flock and anguish in the elements and handled as much as possible to place it in the final portion.
  • The transport of prefabricated elements within the factory depends on the production method selected for manufacturing.
  • The transport of prefabricated elements from the factory to the place of action must be planned in accordance with the traffic rules and regulations stipulated by the authority, the size of the elements is often restricted by the availability of appropriate transport equipment, such as the tractor -am- tailored, to adapt to the load and dimension of the member, in addition
