Abstract: The present invention relates to a modular ramp constructions that facilitate the passage of objects over obstacles on a surface such as a doorstep or a flight of stairs. Specifically the present invention relates to a construction that facilitates the passage of a wheelchair or other appliances used by physically handicapped persons over such obstacles. The construction comprises wedge elements (1) that can be adapted to the given dimensions and requirements of a ramp construction, to which purpose the length of the wedge elements (1) can easily be shortened and where the wedge elements (1) are provided with means (6) for releasable attachment to adjacent tile elements (8) of the modular ramp construction, thereby making it possible quite easily to assemble and afterwards dismantle the construction when it is to be adapted to another application.

Abstract: A cooling roof construction comprising a substantially horizontal roof having a weatherproof membrane, and where a perforated tile layer is arranged a distance above said membrane, where the space between the membrane and the perforated tile layer is connected by at least one conduit to an outside ambient space.
