Erection of Prefabrication in Prefabricated Building

Launch of prefabricated elements

• The fastening of the mounting earrings is attached to the mounting hooks.
• Cleaning of the elements and the erection site.
• Cleaning of steel inserts before incorporation into lifting joints
• Set the elements to correct the position.
• Adjustments to obtain the stipulated level line and plumb line.
• Deats welding.
• Change of erection rigs.
• Placement and removal of the necessary scaffolding/supports.
• Welding of insortslalaying the reinforced in joints.
• The assembly work in several constructions works by using different prefabricated elements with risk conditions, therefore, skilled workers to be employed at work.

Equipment required for erection

• Machinery necessary for extraction, of course, and fine aggregates.
• Transport equipment, such as conveyors, chain conveyors, etc.
• Concrete mixers
• Vibrators
• Assembly equipment such as cranes, cranes, pulleys, etc.
• Transport machines
• Workshop of machinery for the manufacture and repair of steel.
• Machines for stretching, bending and welding bars
• Tools and smaller sockets, such as wheel bars, concrete hubs, etc.
• Steam Generation a plant for accelerated curing
• Planning Coordination
• It is important that the installer/installer and the precaster builder work together to achieve the best performance.

Site access and storage

• Verify site accessibility and delivery of prefabricated panels to the site, especially low platform trailers.
• Check if there is adequate space for temporary storage before installation and ground conditions.
• Irregular terrain will cause overload and crack the panels.
• Crane Arrangement Planning
• Plan the capacity of the crane and lifting gears according to
• The higher weight of prefabricated panels
• Elevation of heights.
• Working radius
• Crane position in relation to the final location of the panel
• Plan another team
• Boom lift and scissor lift to unhook installed panels.
• Lifting gears
• Qualified staff
• Competent crane operators
• Rigging equipment
• Signal equipment
• General considerations for crane selection
• Total lifting weight
• Crane model
• The safe work load for crane
• Lifting capacity must be 1.5 times the total weight
• Lifting and balancing radius
• Crane counterweight
• The length of the crane boom is related to the vertical and horizontal separation of the building.
