BACKGROUND OF INVENTION1. Field of the Invention
This invention relates to an improved weep hole screen and method of installing the same for covering weep holes in masonry buildings.
2. Description of the Related Art
In masonry buildings, the exterior walls are usually provided with a number of weep holes to allow adequate ventilation of the space between the exterior walls and the interior walls. Weep holes are typically formed during exterior wall construction by simply not placing mortar in the gap between two adjacent bricks. Although weep holes are useful for providing ventilation, they also present a problem of intrusion of insects and rodents into the walls.
In view of that problem, a number of types of weep hole screens have been developed over the years. However, each of the prior weep hole screens has significant drawbacks. Most of the existing weep hole screens are designed for installation after the construction of the walls and therefore involve some attempt to fasten the weep hole screens on the exterior of the walls. Examples of such weep hole screens include U.S. Pat. No. 6,360,493 to Torres 111, U.S. Pat. No. 6, 176,048 to Berger, U.S. Pat. No. 6,044,594 to Desselle, and U.S. Pat. No. 5,203,795 to Balamut et al., each of which is incorporated herein by reference. Such designs that involve the use of mechanical fasteners are problematic because of the difficulties of using mechanical fasteners in masonry. Specifically, mechanical fasteners do not readily penetrate and hold in masonry but tend to grind to powder or chip away the masonry. Additionally, some of the existing designs involve movable parts, which unnecessarily increases the level of complexity for manufacture and installation and increases the cost. Because of those drawbacks, it would be a significant advancement in the art to provide a weep hole screen that requires no mechanical fasteners, has no moving parts, is simple and inexpensive to manufacture and install.
SUMMARY OF INVENTIONThe present invention is directed to an improved weep hole screen and method for installing the same in the exterior wall of a masonry building in order to prevent small animals such as insects and rodents from entering the building through the weep hole. A weep hole screen in accordance with the present invention preferably comprises a rectangular mesh screen with an angle bracket attached to each end. The weep hole screen is sized such that the angle brackets sandwich the bricks that form the weep hole on the interior faces of the bricks. The interfaces between the weep hole screen and the bricks are preferably sealed with mortar or another suitable sealant. The weep hole screen may be installed easily during original construction of the wall. Such a weep hole screen is advantageous because it is simple and inexpensive to manufacture and install. By installing the present weep hole screen during original construction, the weep hole screen is cemented firmly in place without the need for mechanical fasteners.
Additionally, the present weep hole screen is located on the interior face of the brick wall, so it is not readily visible from the exterior and is out of the way and not likely to get knocked off by activities occurring on the exterior of the building, such as lawn care and building maintenance.
Disclosed is a method of installing the present weep hole screen about a weep hole formed between first and second bricks in a masonry wall during construction of the wall, each of said bricks having an upper surface, a lower surface, a front surface, a rear surface, and side surfaces, the method comprising the following steps:
(a) applying a first amount of mortar on a mounting surface;
(b) positioning the first and second bricks in spaced relation on a first amount of mortar;
(c) providing a weep hole screen having first and second angle brackets spaced apart from one another and a mesh screen attached to each of first and second angle brackets;
(d) positioning the weep hole screen such that the first and second bricks are at least partially sandwiched between first and second angle brackets and the mesh screen abuts the front or rear surface of each of the first and second bricks;
(e) sealing the weep hole screen to each of the first and second bricks; and
(f) installing a third brick on top of the first and second bricks using a second amount of mortar.
Disclosed is a method of installing Applicant's novel weep hole screen wherein said step(e) above comprises using a third amount of mortar to seal the mesh screen to first and second bricks.
Additionally, disclosed is a method of installing Applicant's novel weep hole screen wherein a first angle bracket comprises first and second flanges, first and second flanges being substantially perpendicular to one another, a second angle bracket comprises third and fourth flanges, third and fourth flanges being substantially perpendicular to one another, the mesh screen being attached to second and fourth flanges, and wherein step (d) above comprises positioning the first flange adjacent the upper surface of each of the first and second bricks; positioning the second flange adjacent the rear surface of each of the first and second bricks; positioning the third flange adjacent the lower surface of each of the first and second bricks; and positioning the fourth flange adjacent the rear surface of each of the first and second bricks.
Referring to FIG. I a weep hole screen 10 in accordance with the present invention comprises a mesh screen 16 which is attached to angle brackets 12 and 14 at either end. The attachment of screen 16 to angle brackets 12 and 14 may be by any suitable means, such as by welding, adhesives, or mechanical fasteners. Screen 16 preferably has holes that are-small enough to prevent insects and rodents from passing through it yet large enough to allow air and moisture to pass through. Angle brackets 12 and 14 and screen 16 may be made of any suitable material, such as metal, plastic, or nylon.

The method set forth in the paragraph above applies as well to the installation of any of the embodiments of the weep hole screen set forth herein and also to the installation on a weep hole created by spaced apart adjacent bricks in a course of bricks above a first course of bricks illustrated in
A preferred method of installing any of the devices set forth herein is on weep holes defined by adjacent bricks on the inner wall of the brick wall, during construction of the brick wall. In an alternate preferred method of installation, the devices may be placed both on the rear (inner) and the front (outer) walls during the construction of the brick wall. Thus, there may be dual coverings on a single weep hole, both at the front and at the rear of the weep holes thereby providing double coverage. That is to say, if one of the front or the rear devices failed, there would still be backup protection from the remaining weep hole screen.
Furthermore, while a preferred method of installing a device on a brick wall is set forth in the paragraphs above, an alternative preferred method of installing devices, either at the front or at the rear or at both the front and the rear of the brick wall, during the construction of a brick wall would provide for the flanges of the devices to be inserted after all of the bricks and mortar below, to either side of the weep hole, and above the weep hole have been installed with mortar and the mortar is still wet. At such a time any of the devices set forth herein can be gently pressed, with the flanges sandwiching the bricks as seen in
Likewise, in
Integral and resiliently or flexibly engaged with the face are the legs 44, 46 which may be provided with crimps 48, 50, so as to facilitate bending of legs during installation. Typically angle A between face 42 and legs 44, 46 is greater than 90° but less than 180°, typically about 135°.
In
The device is placed adjacent to the weep hole and aligned so that the legs are adjacent the brick weep hole side walls. The top and bottom of the weep hole screen is aligned with the top and bottom of the weep hole.
The installation process may be achieved by flexing legs 44, 46 gently inward until they pass the inner faces of side walls of adjacent bricks 24, 25 and then urging screen 10a into the wall until face 42 is about flush with or slightly past (inward of) the front surface 24a and 25a of the bricks. The angle that the legs are bent inward during installation will typically be at or less than 90 degrees. For example, weep hole screen 10a would be inserted so that it is flush with the walls of the brick when the mortar surface is also flush with the brick wall. However, mortar is sometimes smoothed back or recessed from the surface of the brick, in which case, screen 10a would be pushed back past the adjacent brick front wall so that it was adjacent the surface of the mortar course above and below the weep hole.
The height of the alternate preferred embodiment illustrated in
Note in
Turning now to dimensions of the screen or gaps in the louver, it may be seen that the gap (across lower end half moon) or the diameter or longest axis of a round hole or polygonal opening should not exceed about ⅛ inch and not be less than about 1/32 inch. The upper limit would prevent entry of bugs and the like and promote air circulation and the lower limit would allow same, but too small a dimension would inhibit air circulation, to allow access by bugs. The thickness of the material used for the weep hole device, such as the frame and flange is typically about 1/32 inch.
Any of the embodiments of Applicant's present invention may be made from any suitable material. Metal, including stainless steel or aluminum, would help prevent rusting. Galvanized, painted, or powder coating of steel would also inhibit rusting. Moreover, any of the devices may be colored with paint or other suitable coating, including powder coating, and may be of a color including a medium gray to simulate mortar. Plastic may also be used.
Although the foregoing specific details describe a preferred embodiment of this invention, persons reasonably skilled in the art will recognize that various changes may be made in the details of this invention without departing from the spirit and scope of the invention as defined in the appended claims. Therefore, it should be understood that this invention is not to be limited to the specific details shown and described herein.
