All construction is dangerous. Always wear hard hats, eye protection, ear protection (malleting gets very loud), gloves, high visibility outfits and steel-capped boots. Where working at height is required, use a harness. Establish a ‘safety first’ culture on site, and encourage the continuous identification of hazards.
Selected wood glue to be specified by Structural Engineer.
Adhesive to be applied in accordance with manufacturer’s guidance, to clean surfaces free from dust.
Glue line to be held with screws or clamps as necessary to ensure full contact of surfaces until adhesive has cured, with minimum number of screws as shown in details.
Steel screws to conform to BS1210, min tensile strength 550N/mm2.
Unless noted otherwise, screws to be 4mm diameter x 40mm long. Screws should be turned, not hammered, into pre-drilled holes of 2mm diameter. The tops of countersunk screws should be no more than 1mm below the surface of the plywood. A non-corrosive lubricant may be used to facilitate insertion.
