A tub box (20) for use in enclosing an end of a drain pipe (46) in a concrete slab floor of the type having a concrete slab (42) and a vapor barrier film (56), and permitting a plumbing connection to the drain pipe. The tub box comprises a container having side walls (22), a closed bottom (24) and a top edge (28) defining an open top (26), the top being adapted to receive a lid (32); and a radially outwardly-protruding flange (40) on the side walls, axially spaced below the top edge by a distance (D) approximately equal to the thickness of the concrete slab, for sealing attachment to the vapor barrier film. The tub box (20) is used by placing it in the ground (48) on which the concrete slab is to be poured, with the flange at the surface of the ground and the drain pipe extending into the container interior through the opening (44) in the side wall. The vapor barrier film (56) is laid on the ground surface and is sealed to the flange (40). The concrete slab is poured on the ground over the vapor barrier film to a thickness approximately equal to the axial distance between the flange and the top edge of the container.
Une boîte à tuyaux (20) est destinée à enfermer une extrémité dun tuyau de drain (46) dans un plancher à dalle de béton du type comportant une dalle de béton (42) et un pare-vapeur (56), et permettant un raccord de plomberie au tuyau de drain. La boîte à tuyaux comprend un contenant ayant des parois latérales (22), un fond fermé (24) et un bord supérieur (28) définissant un dessus ouvert (26), le dessus étant adapté pour recevoir un couvercle (32); et une bride en saillie se déployant radialement vers lextérieur (40) sur les parois latérales, espacée axialement sous le bord supérieur par une distance (D) approximativement égale à lépaisseur de la dalle de béton, pour étanchéiser laccessoire au pare-vapeur. La boîte à tuyaux (20) est utilisée en la plaçant dans le sol (48) sur lequel la dalle de béton doit être versée, la bride étant à la surface du sol et le tuyau de drain se prolongeant dans le contenant intérieur par louverture (44) dans la paroi latérale. Le pare-vapeur (56) est posé sur la surface du sol et scellé à la bride (40). La dalle de béton est versée sur le sol au-dessus du pare-vapeur à une épaisseur approximativement égale à la distance axiale entre la bride et le bord supérieur du contenant.
