An apparatus for forming a joint between concrete floor slab panels, the apparatus comprising: a divider plate 2 for bounding a side of a concrete floor slab panel; and first and second top strips 4 & 4 respectively, the first top strip 3 being connectable to the divider plate, and the second top strip 4 being frangibly connectable to the divider plate and/or the first top strip. Each of the first and second top strips comprises: an elongate concrete engagement member 9; and a top section 11 comprising an elongate top face 12 presenting an elongate edge 13 configurable to lie at the level of the top surface of a concrete floor slab panel; and an elongate concrete abutment face 14 extending from the elongate edge of the top face, the elongate concrete abutment face extends downward from the elongate edge of the top face at an angle such that the angle between the abutment face and the top surface of an abutting concrete floor slab panel is from 65° to 135° |
