Translucent wall panel

Abstract

A translucent wall panel ( 1 ) comprises a single body of translucent polycarbonate material comprising skin wall means and a multiwall support ( 4 ) extending between the skin wall means. The skin wall means comprises an outer weather wall ( 2 ), an inner liner wall ( 3 ), a longitudinally extending first side ( 5 ) and a longitudinally extending second side ( 6 ) opposite to the first side. The first side ( 5 ) has outer projecting and recess parts and the second side ( 6 ) has outer projecting and recess parts. The projecting and recess parts of the first side ( 5 ) are of mating form with corresponding recess and projecting parts respectively of the second side 6 for engagement between the first side ( 5 ) of one panel A and the second side of another like panel B. The sides ( 5, 6 ) have additional spacer recesses ( 51, 52 ) which are aligned so that when two similar panels ( 50 ) are aligned adjacent to one another as illustrated in FIG. 5 a spacer element ( 60 ) bridges a gap between the panels ( 50 ) and a support frame element ( 80 ) such as a purlin.

         17 . A wall panel comprising a single body of translucent material, the single body comprising skin wall means and a multiwall support extending between the skin wall means, the skin walls and multiwall support all being of translucent material, and the skin wall means comprising an outer wall, an inner wall, a longitudinally extending first side, and a longitudinally extending second side opposite to the first side, the first side having outer projecting and recess parts and the second side having outer projecting and recess parts, the projecting and recess parts of the first side being of mating form with corresponding recess and projecting parts respectively of the second side for engagement between the first side of one panel and the second side of another like panel. 
     
     
         18 . The translucent panel as claimed in  claim 17  wherein the first side has an outer projecting part, an inner projecting part, and an intermediate recess part between the outer and inner projecting parts and the second side has an outer recess part, an inner recess part and an intermediate projecting part between the inner and outer recess parts. 
     
     
         19 . The translucent panel as claimed in  claim 18  wherein the second side of the panel has an integral hole for reception of a fixing. 
     
     
         20 . The translucent panel as claimed in  claim 19  wherein the outer projecting part of the first side extends to cover the fixing hole of a second side of another like panel. 
     
     
         21 . The translucent panel as claimed in  claim 18  wherein the outer projecting part on the first side projects beyond the side edge defined by the inner projecting part and the outer recess part on the second side is recessed further than the inner recess part. 
     
     
         22 . The translucent panel as claimed in  claim 17  wherein at least one side has spacer recesses to receive portion of a spacer bar. 
     
     
         23 . The translucent panel as claimed in  claim 23  wherein both sides have spacer recesses. 
     
     
         24 . The translucent panel as claimed in  claim 23  wherein the spacer recesses are aligned. 
     
     
         25 . The translucent panel as claimed in  claim 17  wherein the translucent material comprises a translucent thermosetting material. 
     
     
         26 . The translucent panel as claimed in  claim 17  wherein the translucent material comprises a polycarbonate material. 
     
     
         27 . The wall structure incorporating a translucent panel as claimed in  claim 17 . 
     
     
         28 . The construction system comprising at least one translucent panel as claimed in  claim 17  and a spacer means for bridging a gap between the panel and a support. 
     
     
         29 . The system as claimed in  claim 28  wherein the spacer comprises a spacer for supporting one edge of the translucent panel. 
     
     
         30 . The system as claimed in  claim 28  wherein the spacer comprises a spacer for supporting adjacent edges of two adjacent translucent panels. 
     
     
         31 . The structure incorporating a construction system as claimed in  claim 28 .
