Abstract
A drainage device for use under the floor of a building to facilitate drainage of water along a foundation of the building under the floor. The drainage device can include a corner drainage device that is capable of assuming a number of near 90 degree shapes so that the drainage device can be easily fitted to the corner of the foundation. A bridge drainage device permits more rapid installation of the drainage devices. The bridge device can be used to bridge between two drainage devices so that it is not necessary to cut the drainage devices precisely to fit on a footing of any selected length.
Claims17
A corner drainage device comprising:
- a first wall member having a foundation section and a footing section,
- a second wall member having a foundation section and a footing section,
- a first hinge joining the first and second wall members to permit pivoting of one of the first and second wall members relative to the other of the first and second wall members to form a corner at the first hinge, and
- wherein the footing section of the second wall member includes an overlap portion configured to overlap the footing section of the first wall member when the first hinge forms the corner, the overlap portion configured to overlap the footing section of the second wall member in closely conforming engagement at infinite increments of overlap to permit formation the corner at the first hinge.
A drainage system for use under a floor in a structure including the floor, a foundation wall, and a footing located below the foundation wall, the drainage system comprising:
- a first drainage device configured to fit on the footing adjacent the foundation, the first drainage device being formed with a series of feet projecting down from the first drainage device for spacing the first drainage device off of the footing to permit water to flow under the first drainage device;
- a second drainage device configured to fit on the footing overlapping and nested with the first drainage device, the second drainage device being formed with a series of feet projecting down from the second drainage device for spacing the second drainage device off of the footing to permit water to flow under the second drainage device;
- a third drainage device configured to fit on the footing adjacent the second drainage device, the third drainage device being formed with a series of feet projecting down from the third drainage device for spacing the third drainage device off of the footing to permit water to flow under the third drainage device
- a bridge drainage device configured to bridge the second and third drainage devices, the bridge drainage device being formed with smooth surfaces to prevent nesting engagement with the feet of at least one of the second and third drainage devices.
A bridge drainage device for use under a floor in a structure including the floor, a foundation wall, and a footing located below the foundation wall to bridge between first and second drainage devices, the bridge drainage device being constructed for placement on the first and second drainage devices on the footing adjacent the foundation wall prior to installation of the floor to permit water to flow along the footing under the floor, the bridge drainage device comprising a wall member for bridging the first and second drainage devices, the wall member having a first surface facing away from the footing and foundation wall when the bridge drainage device is placed on the drainage devices on the footing, and a second surface facing generally toward the footing and the foundation wall when the bridge drainage device is placed on the drainage devices on the footing, the wall member comprising a wall section for facing the foundation wall and a footing section for facing the footing, the wall member being free of protrusions for nesting with at least one of the first and second drainage devices.
