Abstract

The present invention relates to a floor drainage assembly for inhibiting water from passing from one floor of a building to an other floor of the building. The one floor is disposed above the other floor. The one floor includes a stairwell threshold. The building has a stairwell connecting the one floor to the other floor. The one floor is in communication with the stairwell via the stairwell threshold. The floor drainage assembly includes a stairwell drain and a stairwell trough. The stairwell trough extends along the stairwell threshold. The stairwell trough is in fluid communication with the stairwell drain, whereby water from the one floor that enters the stairwell threshold is at least partially captured by the stairwell trough and directed to the stairwell drain. The assembly inhibits the water from damaging the other floor thereby.

Claims

1. A threshold plate for extending along a door threshold connecting a first room and a second room, the threshold plate comprising:

a first portion at least partially disposed towards the first room and having a plurality of apertures extending therethrough, the apertures positioned to receive water passing over the threshold plate, the first portion operatively connectable to a drain via said apertures; and

a second portion at least partially disposed towards the second room and having a plurality of apertures extending therethrough, the apertures of the second portion positioned to receive water passing over the threshold plate, the second portion operatively connectable to a drain via said apertures of the second portion.

2. The threshold plate as claimed in claim 1, wherein the first portion is angled so as to partially face the first room, whereby, if water floods the first room, the first portion at least partially contains the water within the first room and at least partially directs the water to the drainage system;

and wherein the second portion is angled so as to partially face the second room, whereby, if water floods the second room, the second portion at least partially contains the water flooding the second room within the second room and at least partially directs the water flooding the second room to the drainage system.

3. The threshold plate as claimed in claim 2, wherein the threshold plate is isosceles trapezoid shaped in cross-section.

4. The threshold plate as claimed in claim 1, including a base abutting the first room and the second room, the threshold plate having a seal connected to the base, the seal extending along the door threshold to inhibit water from passing therebetween.

a stairwell drain; and

a stairwell trough extending along the stairwell threshold, the stairwell trough being in fluid communication with the stairwell drain, whereby water from the one floor that enters the stairwell threshold is at least partially captured by the stairwell trough and directed to the stairwell drain, the assembly inhibiting said water from damaging the other floor thereby.

6. The assembly as claimed in claim 5, the building further including a hoistway connecting the one floor to the other floor, the one floor further having a hoistway threshold and being in communication with the hoistway via the hoistway threshold, and the assembly further including:

a hoistway trough drain; and

a hoistway trough extending adjacent to the hoistway threshold, the hoistway trough being in fluid communication with the hoistway trough drain, whereby water from the one floor seeking to enter the hoistway threshold is at least partially captured by the hoistway trough and directed to the hoistway trough drain, the assembly further inhibiting water from damaging the other floor thereby.

7. A building having a first floor, a second floor disposed above the first floor, the second floor including a stairwell threshold, a stairwell connecting the first floor to the second floor, the second floor being in communication with the stairwell via the stairwell threshold, and a floor drainage assembly including:

a stairwell drain extending below the second floor; and

a stairwell trough extending along the stairwell threshold, the stairwell trough being in fluid communication with the stairwell drain, whereby water from the second floor that enters the stairwell threshold is at least partially captured by the stairwell trough and directed to the stairwell drain.

8. The building as claimed in claim 7, further including a catch basin disposed below the second floor, the catch basin being at least partially filled with drainage water up to a waterline, the stairwell drain connecting to the catch basin and at least partially extending below the waterline.

9. The building as claimed in claim 7, wherein the stairwell trough is adjacent to the stairwell, the second floor further including a room, and the floor drainage assembly further including an additional stairwell trough extending along the stairwell threshold, the additional stairwell trough being adjacent to the room and being in fluid communication with an additional stairwell drain, the additional stairwell drain further capturing water from the second floor that enters the stairwell threshold.

10. The building as claimed in claim 9, further including a catch basin disposed below the second floor, the stairwell drain connecting to the catch basin, the stairwell drain connecting the stairwell trough to the catch basin and the additional stairwell drain connecting the additional stairwell trough to the catch basin.

11. The building as claimed in claim 10, the floor drainage assembly further including a stairwell pipe having an interior and a divider disposed within the interior of the stairwell pipe, the divider being shaped to split the stairwell pipe into a first part and a second part sealed from the first part, the first part of the stairwell pipe being part of the stairwell drain and the second part of the stairwell pipe being part of the additional stairwell drain.

12. The building as claimed in claim 7, the building further including a hoistway connecting the first floor to the second floor, the second floor further having a hoistway threshold and being in communication with the hoistway via the hoistway threshold, and the assembly further including:
