My shed foundation consisted of 9 concrete filled post holes, with a 200 mm post bracket embedded in each. I worked on the corners first, and placed the portholes and brackets at 2800 centers. This provided a 100 mm overhang on each end. The intermediate posts we place between the centre of the 2800 spaced posts, or at 1400 mm apart. I then placed 3 - 100 x 100 posts horizontally to act as the beams, and then place 150 x 45 joints perpendicular to the beams. All joints tied in with coach screws. Between each joist, l placed spacers for stability staged at approximately 600 centers.
Cauda equina ("horse's tail") is the name given to the lumbar and sacral nerve roots within the dural sac caudal to the conus medullaris. Cauda equina syndrome is usually the result of a ruptured, midline intervertebral disk, most commonly occurring at the L4 to L5 level. However, tumors and other compressive masses may also cause the syndrome. Individuals generally present with progressive symptoms of fecal or urinary incontinence, impotence, distal motor weakness, and sensory loss in a saddle distribution. Muscle stretch reflexes may also be reduced. The presence of urinary retention is the single most consistent finding (Perron and Huff, 2002).
Racking usually sits in a busy and potentially dangerous environment. You have many safety responsibilities under the Australian Standards. Regular scheduled inspections are needed to make sure your racking is safe and conforms to the Australian Standard and local worksafe requirements. For full information, please visit our website, where we have a 4-page guide outlining how to inspect, test and maintain your racking. If you want us to do it we are happy to oblige. We do your first one free anyway.
