A drainage system for use in concrete masonry unit (CMU) wall construction comprises a tray unit of a size corresponding to size of CMUs, to be received beneath a course of CMUs, in use. The tray unit comprises opposite side flanges to abut a superjacent CMU and supporting a pan therebelow. The pan may be angled from back to front and from side edges to a middle portion thereof to urge water toward a front middle portion of the tray.
This application is a continuation-in-part of Ser. No. 10/442,748, filed on May 21, 2003.
Single wythe masonry walls are constructed using concrete masonry units (CMUs). CMUs are sometimes referred to as cinder blocks. A CMU consists of a hollow rectangular building block typically having a central web providing two vertical cores or cavities. It will be understood that a CMU can have any number of configurations including one wherein only a single core is present. In single wythe masonry wall construction a foundation is formed, typically of concrete. The wall is formed by laying the CMUs in alternating fashion in multiple courses depending on the height of the wall. Owing to the construction, the vertical cores of CMUs are aligned to provide a continuous channel from the top of the wall down to the foundation. Mortar is used in joints to join the CMUs.
In accordance with the invention, there is provided a drainage system for use in concrete masonry unit (CMU) wall construction. The CMU may have one or more cores or cavities defined therein.
FIG. 1 is an exterior perspective view of an embodiment of a drainage system in accordance with the invention used in a single wythe masonry wall formed by courses of concrete masonry units (CMUs);
CMUs 26 most typically have a nominal height of eight inches, a nominal length of sixteen inches and come in nominal widths of eight, ten or twelve inches. Actual sizes are about {fraction (3/8)} inches less to allow for a ⅜-inch mortar joint. The CMU 26 comprises a hollow concrete block 34 having a web 35 to provide a pair of vertically extending hollow cores or cavities 36 therethrough. The hollow cores or cavities 36 are typically about five inches square. In conventional single wythe masonry wall construction, a first course 24-1 of CMUs 26 is secured to the foundation wall 28 with a layer of mortar. Mortar is also provided between adjacent CMUs 26. A layer of mortar is then placed upon the first course 24-1 and the second course 24-2 is laid on the first course 24-1. Again, mortar is provided between each CMU 26. The CMUs 26 in each course are typically offset from one another as illustrated in FIG. 1. As a result, the vertical cores 36 in any course 24 are aligned with the vertical cores 36 in other courses 24 to provide a continuous channel from the top of the wall down to the foundation wall 28, as is well known.
The strips 40 are of a water permeable material having a thickness in the range of about {fraction (1/8)} inch to {fraction (1/2)} inch with {fraction (1/4)} inch being typical. The strips 40 are adhered in any known manner to the pans 56 and 58 and extend transversely beyond the front edge 62 of the pans 56 and 58 and also beyond front flange 44. The strips 40 function to permit water to pass therethrough and to substantially prevent mortar and other debris from passing therethrough. The material is preferably a non-absorbent water-permeable, fibrous mesh material formed with circuitous (non-linear) pathways. The material is preferably a mass of random filament-type plastic fibers. The strip may also include an outer layer of backing material. The backing material may be a finely woven paper like material, which will pass water but not fine debris, such as vermiculite or the like. Overall, the material is sufficient to catch and support mortar and debris without significant collapse, but allow water to pass freely therethrough. The strips 40 may be secured with a suitable adhesive or molded in situ with the tray unit 38.
Referring to FIG. 8, the block 32 comprises a T-shaped sheet 72 of water permeable material, similar to material of the strips 40. The sheet 72 has a thickness in the range of about {fraction (1/8)} inch to {fraction (1/2)} inch with {fraction (1/4)} inch being typical. The sheet 72 has a top part 74 wider than a CMU core 36 and a bottom part 76 narrower than a CMU core 36. For example, with a CMU having a 5×5 inch core, the top part 74 might be about six to eight inches across and about seven inches tall, while the bottom part 76 might be on the order of four inches across and four inches tall. The block 32 is then stuffed in a core 36 of the first course 24-1 by bending the bottom part 76 so that it extends horizontally and thus perpendicular to the top part 74 and then curving opposite ends 78 and 80 of the top part 74 to conform to the walls of the core 36. As a result, the curve of the top part 74 gives stability to the mesh material to withstand impact of falling mortar.
FIG. 18 illustrates yet another preferred embodiment of the present invention. In particular, tray 230 comprises a tray unit 238 and a pair of strips 240 of water permeable material. The tray unit 238 may be constructed of a one piece molded plastic construction and has length less than that of a CMU so that it can be set in mortar and the mortar will set up and secure the tray unit 238 in position. For example, the length of the tray unit 238 may be on the order of twelve inches. The width may be reduced like the tray shown in FIG. 15 so that it extends from the front edge of a CMU inwardly a distance of at least about one inch past the inside face of the CMU.
a tray unit sized and shaped to be received beneath one or more CMUs, in use, the tray unit including a peripheral flange;
12. The drainage system of claim 11 wherein the block is taller than a CMU so that the top part bends to conform to a CMU core and the bottom part extends horizontally to cover a portion of the strip disposed in a CMU core.
