Each of the cantilever supporting structures has (1) a post with a top end and a bottom end, the bottom end being engaged to the ground; (2) an anchor span having a haunch height from a bottom end of the anchor span to the ground; and (3) a cantilever span. The anchor span and the cantilever span are coupled to the top end of the post. The anchor span slopes downwards from the top end of the post and the cantilever span slopes upwards from the top end of the post. A first roof covers the first row of cantilever supporting structures. A second roof covers the second opposing row of cantilever supporting structures. The first row of cantilever supporting structures and the second opposing row of cantilever supporting structures form only two pole lines.
Description
- 1. Field of the Invention
- The present invention generally relates to a clear span building structure. More particularly, the present invention relates to a clear span building structure having two rows of supporting columns that minimizes construction and labor costs and maximizes flexibility in floor plan designs, such as for a dairy cattle housing facility.
- 2. Discussion of the Related Art
- Free stall dairy barns have become an attractive option for dairy farmers who want to maintain and manage a large dairy herd. The advantages of the free stall housing system over other confined herd arrangements, such as tie stall barns, are well known. These advantages include reduction of bedding per cow, less space per cow, ease of manure removal, reduced udder washing time before milking, higher milk quality, and less frequent udder injury.
- A free stall barn requires a building design that is similar to conventional loose housing, but with stalls and lanes constructed to define resting areas, watering areas, feed areas, and cow lanes for the cows to walk to and from a milking center. In the resting areas, free stalls are arranged in parallel rows with adjacent concrete alleys that provide safe, convenient passages for the cows to other parts of the free stall barn and other parts of the housing system. The resting areas are often bedded with sand or organic material. The alleys have gutters or other mechanisms for collecting manure, which is flushed into a manure handling tank. Each resting area also has a feed alley where the cows feed themselves. These are normally located adjacent and parallel to a feed drive-through or feed driveway/alley. There is a barrier between the feed alley and the drive-through, which can include a row of feed stanchions.
- A feed table of about two to three feet in width typically lies along the barrier on the drive-through side, and the cows place their necks and heads over or through the barrier to eat the feed that is distributed on the feed table (i.e., the sides of the feed driveway/alley). Normally, a feed vehicle is driven along the drive-through to bring the feed. The feed is spread out on the feed tables that lie along both sides of the feed drive-through. The milking of the cows is carried out at a milking parlor located outside the barn. A single milking parlor may service several free stall barns.
- Various types of free stall barn building structures are utilized by dairy farmers. One type of a free stall barn structure is a hanger-type barn where the entire barn is enclosed, or mostly enclosed, much like that of an airplane hanger. In certain locales, these hanger-type barns become very hot during the summer months, ventilation is poor inside, and additional cooling fans and mist sprayers may be utilized to cool the cows housed therein.
- FIG. 1 illustrates a cross-sectional view of a conventional open-air-type tiered barn structure having two opposing sloping roofs and a central-tiered roof, all of which are supported by six rows of supporting posts/columns (having first to sixth pole lines) than run along a length of the barn structure. In the tiered-roof barn structure illustrated in FIG. 1, a central alley driveway is provided in the middle and along the length of the barn structure underneath the central tiered roof, while the left roof and the right roof each have underneath a free stall area (where the cattle reside). Feed stanchions are provided as a boundary along the central alley driveway so that the cattle may stick their heads through the stanchions to eat the feed placed at each side of the central alley driveway. The central alley may be wide enough to accommodate a vehicle, such as a pickup truck, so that the dairy operator may drive down the central alley through the barn structure to drop off the feed along the length of the barn.
- Existing cow housing facilities are generally supported by four, six, or more rows of supporting columns. Because of the number of rows of supporting columns, or pole lines, the layout of the dairy cattle housing facility, such as the position and location of alleys, fence lines, gate lines, and stanchion lines, etc., must be designed around the pole lines. These impediments limit the most efficient design layout of the building structure, for example, a free stall barn. Moreover, like the hanger-type barn structures, cooling fans and mist sprayers are typically still utilized to facilitate ventilation and to cool the cows housed within the barn structure, as in FIG. 1. Furthermore, it is important to ensure that the cows are dry, clean, and comfortable, as it is well documented that cows that are dry, clean, and comfortable produce significantly more milk and of higher quality.
- Dairy cattle barn structures are a major investment for dairy owners and operators, as each barn structure requires significant construction costs and labor to build. Moreover, existing dairy cattle barn structures typically require cooling fans and mist sprayers to improve ventilation within the barn structure and to keep the cows cool, which require electricity to operate. Accordingly, there is a need for an aesthetically-pleasing barn structure having a simple design and lower cost, being relatively easy to construct, and having good ventilation and cooling characteristics, while still capable of providing protection from direct sunlight, wind, and rain.
