Floor or roof panel support bolt - with adjustable intermediate bearing member between main bearing member and base plates

摘要

This is for use under roof or floor panels supported on uprights, e.g. in data-processing unit floor structures, with a bearing member on the support bolt for the ends of four base plates. The intermediate bearing member may comprise a piece of base plate with a cover sheet plate with holder pieces, and with a slit for the support bolt. This can be readily used where steel reinforcing bars form an obstruction.
