ERECTION

Erection is the last step in the process of pre-engineered buildings and steel structures. At this stage, all the components will be erected at the site and connected to each other by bolts.

PRINCIPLES OF ERECTION

Erecting columns to join the purlin (if any) ties the columns together. The column has been arranged neatly then the roof has been erected.
Erecting the frame inside and then proceeding outside (along the path of the crane – see the construction – organising drawings)
The erection should be started from the diagonal brace (tied column and roof).
Fix two mounting frames at the diagonal brace before installing the adjacent bracket. This process is translated into the next frame.
During the erection, there must be a temporary brace. Using the roof purlin and wall purlin is combined with the cable tie to position, link the frames together.
Installing the steel panels after calibrating the truss, straight purlins, being clean, paint finishes complete scratches on rafters and purlins.
When finishing cover: frequently use chalk or string to position or to mark the mold to balance the panels.
When walking on the roof, you have to put your foot on the lower wave (cathode waves). If you step on the high waves, you will hit the tole, which may cause diarrhea or leakage.
Do not walk up the light panels.

ERECTION PROCESS

Step 1: Preparing to erect Inspection of installation equipment and materials: quantity, safety, quality of materials, etc.
