Abstract
Drywall sheets and other construction materials may be more easily transferred into and within a partially completed building shell by the use of a drywall slideboard. The drywall slideboard consists of upper and lower hinge plates separated by a horizontal hinge. The upper hinge plate supports a removable top plate, which in turn supports a slide plate of a relatively low friction coefficient material. The lower hinge plate is supported by retaining members which permit the drywall slideboard to be temporarily installed upon a section of lumber stock such as a two by four for use, or alternatively the top plate and slide plate may be easily removed from the remainder of the slideboard. Methods of use are further described in which the drywall slideboard may be installed over a two by four or similar material at a window opening and used to facilitate the transfer of building materials into or out of the structure, or alternatively the drywall slideboard may be used to transfer materials up or down a stairway when only the top plate and slide plate are used.
