SITE VISIT 2

The second site i visited was located in the Paramount Industrial Development, in Deer Park, just a few minutes off the Western Ring Road. It is being constructed by TCC Builders, and was designed by Steven Deandra (Arch.)

The above image shows the spacing of the portal frames.
Safety mesh, 'C' purlins and bracing between the purlins is also easily identifiable.

A close up of the knee joint, showing stiffening plates on either side of the stanchions (column) flanges, which assist in making the connection at the knee joint more rigid.


The 'I' beam supporting the apex has a much smaller cross-sectional size compared to the stanchions.
Haunching is also evident at the apex, helping to reduce deflection of the rafters.

The above image shows the HD bolts which have been cast into the pad footing and secure the stanchion to the ground through a base plate.
A welded cleat is also visible and connects the pre-cast panel to the stanchion.

The two panels in the above photo are acting as lintels over an opening. They are seated on steel cleats to support them, and then later connected by a steel plate and bolts which are secured into ferrels cast into the panels. The joint will later be covered over.



The above three images show how the 'C' purlins are supported when there is not a portal frame in place to support them. A long steel cleat is secured to the pre-cast panles to support them, and a smaller cleat on the far side of the purlin is bolted through to keep them upright.
