PCT No. PCT/GB95/02456 Sec. 371 Date Jun. 3, 1997 Sec. 102(e) Date Jun. 3, 1997 PCT Filed Oct. 18, 1995 PCT Pub. No. WO96/12855 PCT Pub. Date May 2, 1996A field limitation joint has a core (101) of closed cell synthetic elastomer and aluminum L-section side members (102). The core is adhered to the side members by double sided adhesive strip (103) of the type having reinforcing filaments (104) running along the length of the strip. The core is pre-compressed and held in compression by tapes (105, 106). These are fabric reinforced and incorporate a central strip (107) of polymer film rendering them non-adhesive along their center. Also they have perforations (108, 109) along their length at the edge of the strip (107). The adhesive edges (110) of the tape (105) are adhered to the outside of upright limbs (111) of the side members and pass over the top of the side members. The perforations (108) run along the top edge of the side members. The other tape (106) extends between the other limbs (112) of the side members on their undersides, again with the non-adhesive strip preventing adhesion to the core (101). On installation onto adhesive to which tiles also are to be set, the tapes maintain the compression of the core. After laying of the tiles, the compression is released by ripping of the top tape along its perforations (108). |
