PROCEDURE AND HARDWARE FOR USE IN THE CONSTRUCTION OF WASTE WATER PIPES IN THE PALM floors

摘要

When laying waste-water pipes in so-called hollow floor structures, a straight waste pipe (6) is fitted with a moulding (12) and a pipe-bend (7, 8) for connection to a waste collecting pipe (4) and to a sanitary appliance respectively. The waste pipe (6) is inserted into a hollow channel (2) in the floor structure (1), with the pipe-bend (7, 8) first, where after pipe-bend (7, 8) is lifted up into a hole drilled from the floor surface down into an underlying hollow channel, and secured in the hole. The sanitary appliance, or apparatus, can then be connected to the pipe-bend (7, 8) and the moulding (12) connected to the collecting pipe (4). The pipe-bend (7, 8) is fixed in the hole at a determined height therein with the aid of a device (18) having the form of an arm of inverse L-shape.
