Scope/Solutions
The unitized curtain wall units for a new high-rise building are fabricated with first anchors and sleeve blocks that attach the curtain wall to anchorage plates cast into the building structure. During construction, nail gun fasteners penetrated the sleeve blocks. The curtain wall fabricator required the contractor to test their capacity with the penetrations. SGH performed the testing to help the contractor determine whether or not the punctured sleeve blocks were structurally adequate.
SGH performed physical testing on samples of the aluminum sleeve blocks and fist anchors. We tested samples with and without penetrations so the project team could compare their capacity. Highlights of our work include:
