Channelled structural elements

Abstract

Abstract A STRUCTURAL ELEMENT IS COMPRISED OF AN ELONGATED BODY MEMBER HAVING A CHANNEL EXTENDING ALONG ONE OF ITS SIDES, THE CHANNEL HAVING IN CROSS-SECTION AN OPEN MOUTH AND A CHANNEL FLOOR BETWEEN TWO LATERAL CHANNEL WALLS. A THREADED SLOT EXTENDS ALONG THE LENGTH OF THE CHANNEL FLOOR AND IS SUBSTANTIALLY U-SHAPED IN CROSS-SECTION, HAVING THREADS RUNNING LONGITUDINALLY ALONG ITS SLOT WALLS. FIRST AND SECOND CHANNEL-WALL GROOVES ARE POSITIONED OPPOSITE EACH OTHER IN THE TWO LATERAL CHANNEL WALLS AND EXTEND LONGITUDINALLY ALONG THE LENGTH THEREOF. THE STRUCTURAL ELEMENT MAY INCLUDE BRACKETS SECURED IN THE CHANNEL BY BOLTS THREADABLY ENGAGING THE THREADED SLOT, SHEET MEMBERS ENCLOSED WITHIN FRAMES FORMED BY A PLURALITY OF BODY MEMBERS, SHEET MEMBERS SLIDABLY INSERTED WITHIN THE CHANNELWALL GROOVES AND HELD THEREIN BY A SPRING ELEMENT BETWEEN THE CHANNEL FLOOR AND THE SHEET MEMBER, AND CROSS-SHAPED BRACKETS FOR SECURING TWO BODY MEMBERS TOGETHER BY BOLT MEANS THREADABLY ENGAGING THE THREADED SLOTS OF THE RESPECTIVE BODY MEMBERS. A MODIFICATION OF THIS STRUCTURAL ELEMENT INCLUDES APERTURES EXTENDING THROUGH THE BODY ELEMENTS TRANSVERSE TO THE LONGITUDINAL AXIS OF THE CHANNEL AND A SECOND APERTURE EXTENDING INWARDLY FROM THE END OF THE BODY MEMBER IN COMMUNICATION WITH THE FIRSTMENTIONED APERTURE.
