摘要： Hollowcore apparatus for forming a concrete hollowcore slab, comprises a casting bed (1), side wall elements (2) extending longitudinally of the casting bed (1) for defining sides of a casting mould, at least one non-sacrificial inflatable core former (23), at least one, preferably non-sacrificial sleeve (24) for substantially receiving the core former (23), the core former (23) and the sleeve (24) being interconnected and the in use sleeve (24) being turnable inside out by removal of the core former (23) from the casting bed1,and at least one holder (57) for preventing or limiting uplift of the in use inflated core former (23) and sleeve (24) relative to the casting bed (1). A method and hollowcore slab are also provided.

摘要： A barricade component (10) comprises an endless perimeter wall (16) defining a geometric shape in a front-to-back plane. At least two circumferentially spaced-apart connecting lugs (14) are also provided on the perimeter wall (16) for interconnecting like or similar barricade components (10) and these extend in an axial top-to-bottom direction. A reinforcement cage (44) is within the perimeter wall (16) and the lugs (14), and at least one elongate truss (48) extends in a circumferential direction and an axial direction within the wall from one said lug (14) to the other said lug (14). A method of interconnecting a plurality of said barricade components (10), and a method of forming such a barricade component (10) are also provided.
