Portable Radiant Heater for Performing Splices in Waterstops

摘要

A portable radiant heating apparatus is provided for performing splices in waterstops. The heating apparatus includes a pair of radiant quartz heating elements that are mounted intermediate the end members of a generally rectangular-shaped frame. The heating elements are preferably positioned in parallel fashion one above the other. Heat deflecting shields are mounted to the top and bottom frame members proximate to the heating elements to concentrate the radiant heat along the sides of the heating apparatus. A splicing operation is performed by positioning the ends of two waterstop sections to be joined adjacent to and on opposite sides of the heating apparatus so that the ends of the two waterstop sections are exposed to the radiant heat from the heating apparatus. Once the waterstop sections have been sufficiently heated to cause the ends thereof to begin to melt, the waterstop sections are removed from the heating apparatus and the ends therefor pressed and held together until the waterstop material cools, thereby forming a water-tight seam.
