<p>Dowels (10, 11, 12) and (13) are V-shaped or U-shaped and bridge a joint (17) between adjacent concrete slabs. Legs (15) and (16) are imbedded in one slab and the apical or bend section (18) up to the juncture line (17) between the slabs may be greased and with an insert (14) in place it results in the apical section being free to move back and forwards in the corresponding slab relatively speaking. The dowel (11) is located inside a sleeve (19) as lost form work in one of the slabs as for the insert (14). The dowel (11) has its apical region (18) in position by reason of stops (20) and (21) inside the sleeve (19). The capacity of the assembly may be supplemented by an additional dowel (11) shown in phantom which is nested inside the first dowel.</p> |
