A mounting flange 4 for a drain well has, along a circumferential edge 14, downwardly directed edge portions which are designed to lie within the edges in a hole 9 for the drain well 1 cut out in a floor element 10, the downwardly directed portions having outwardly directed support portions designed to bear from above against beam tier elements positioned below the floor element 10. In order to facilitate hole-cutting in the floor element, improve the fixing of the drain well, the floor element and the beam tier elements in relation to one another and also improve the sealing between the floor element and the mounting flange, the support portions 24-27 extend along four sides 15-18 of the mounting flange 4 and are designed so as on the one hand to allow anchoring of the support portions 24-27 on the beam tier elements 5-8 lying below by means of fastening members 28 distributed along the support portions 24-27, and on the other hand to form a bottom in elongate gaps S between the downwardly directed edge portions 19-22 of the mounting flange 4 and the surrounding edges of the hole 9 in the floor element 10 in order to prevent sealing material introduced into the gaps S falling out of these gaps S at the bottom. <IMAGE> |
