EXPANSION JOINT PROFILE FOR CONCRETE SLABS
The expansion joint profile (1) includes a square U-shaped channel section (2) with open ends (3,4), a base (5), a first arm (6) and a second arm (7). A first L-shaped flange (8) is displaced from the open end (3) of the channel section (2) prior to securing one leg (9) of the flange (8) to the inner surface (10) of the first arm (6) of the channel section (2). The second leg (11) of the flange (8) extends outwardly from the first arm (6) of the channel section (2). A second L-shaped flange (12) is displaced from the open end (3) of the channel section (2) an equal length as the first flange (8) prior to securing one leg (13) of the flange (12) to the inner surface (14) of the second arm of the channel section (2). The second leg (15) of the flange (12) extends outwardly from the second arm (7) of the channel section (2). A second expansion joint profile (16) identical in construction to the first expansion joint profile (1) - is placed such that its non-flanged channel section (17) overlaps with the exposed flange legs (9,11,13,15) of the first expansion joint profile (1). Stakes (21) through apertures in each of the channel sections (2) and legs (9,13) secure the expansion joint profiles (1,16) to the ground (23) to position the legs (11,15) substantially vertically. Concrete is poured to either side of the expansion joint profiles (1,16) ensuring that the internal of channel section (2) is filled with concrete (24) and ensuring that the exposed external surfaces of legs (11,15) and the channel section (2) are covered with concrete (25).
