Thermal insulating plate for soil heating installation - has distributed polygonal pads on truncated pyramid connectors on top surface with interconnecting channels and ribs

摘要

The plate has pads regularly distributed on the top surface, each pad (2) being connected to plate (1) by a connector (3). The connector widens out, as a shoulder, from the pad to the plate top. Each pad may be of polygon form and the connector shaped like a truncated pyramid. The pads may be placed at the nodes of a regular quadrilateral with a straight channel, width (d), between two diagonal rows of pads. The points and connectors may be joined by ribs (5) and vacuum covered by a watertight thermoformed film. ADVANTAGE - Simple and economic, supports without deterioration, providing good protection of channels.
