Definitions
- This invention relates generally to the fire suppression and extinguishment field, and more specifically to a new and improved sprinkler system and method of installation in the fire suppression and extinguishment field.
- Fire sprinkler systems have been used in the United States to protect warehouses and factories for over one hundred years. Fire sprinkler systems are positioned near the ceiling of a room where hot "ceiling jets" spread radially outward from a fire plume. When the temperature at an individual sprinkler reaches a predetermined value, the thermally responsive element in the sprinkler activates and permits the flow of water as a water jet through an orifice toward a deflector. The metal deflector redirects the water jet into thin streams or "ligaments" that break up into droplets due to surface tension.
- a typical sprinkler has a coverage area of 200 ft 2 (18.5 m 2 ), which is typically measured in a circular pattern with a radius of 8 feet (2.5 m) or in a square pattern with equal sides of 14 feet (4.25 m).
- a typical metal building includes at least three beams, such as rafters, extending along the width of a space and separated from each other by a distance of 25-30 feet (7.5m to 9m).
- a conventional fire sprinkler system for a typical metal building includes four supply lines, each with four typical sprinklers.
- FIGURES l and 2 are perspective and overhead views, respectively, of a fire sprinkler system with two supply lines, each with eight new sprinklers, according to the preferred embodiments.
- FIGURES 3 and 4 are perspective and overhead views, respectively, of a conventional fire sprinlder system with four supply lines, each with four typical sprinklers, according to the teachings of the prior art.
- FIGURE 5 is a detailed view of the coverage area of the sprinkler of the preferred embodiment.
- FIGURE 6 is a side view of the fire sprinkling system according to a variation of the preferred embodiment in a metal building with purlins.
- FIGURE 7 is a detailed view of a portion of FIGURE 6.
- the fire sprinkler system 10 of the preferred embodiments includes a supply line 12 and a series of sprinklers 14 connected to the supply line 12.
- the fire sprinkler system 10 of the preferred embodiments is preferably installed in a space having a width Wi of at least 20 feet (6m) and a length Li of at least 20 feet (6m), and is more preferably installed in a space having a width of at least 20 feet (6m) and a length of approximately 25-30 feet (7.5m to 9m).
- the space is preferably defined by two beams 16 extending along the width of the space and separated by a distance equal to the length of the space. The beams 16 function to support the weight of the roof (shown in FIGURE 5).
- the beams 16 are preferably steel I-shaped rafters 16, but the beams 16 may be any suitable structural member to transfer the weight of the roof, may be made from any suitable material, and may be shaped in any suitable manner.
- the height of the space is preferably 20 to 40 feet (6 to 12m), but may alternatively be any suitable height.
- the space may include a series of purlins 18 extending the length of the space and separated by a distance of approximately 5-6 feet (i-2m). The purlins 18, which span lengthwise between the rafters 16 and are fixed onto the rafters 16, function to support the weight of the roofing sheets (not shown) of the roof.
- the purlins 18 are preferably steel Z-shaped purlins 18, but the purlins 18 may be any suitable structural member to support the roofing sheets of the roof, may be made from any suitable material, and may be shaped in any suitable manner.
- the fire sprinlder system 10 is installed in a metal building (such as a prefabricated metal building), but the fire sprinkler system 10 may alternatively be installed in any suitable shelter.
- the supply line 12 of the preferred embodiments functions to supply a fire suppressing or extinguishing substance to the sprinklers 14.
- the supply line 12 preferably supplies water to the sprinklers 14, but may alternatively supply any suitable substance that suppresses or extinguishes fires.
- the supply line 12 preferably extends along the width Wi of the space, and is preferably located between the beams 16. More preferably, the supply line 12 generally bisects the distance between the beams ⁇ 6.
- the series of sprinklers 14 of the preferred embodiments function to disperse the fire suppressing or extinguishing substance in a coverage area having a length L2 and a width W2.
- the width W2 of each coverage area is less than the length L2 of each coverage area.
- the width W2 of each coverage area is less than 66% of the length L2 of each coverage area.
- the width W2 of each coverage area is less than 33% of the length L2 of each coverage area.
- the length L2 of each coverage area is at least 20 feet (6m) and the width W2 of each coverage area is approximately 5-6 feet (i-2m).
- the length L2 of each coverage area is approximately equal to the distance between the rafters 16 of the space, and the width W2 of each coverage area is approximately equal to the distance between the purlins 18.
- the length L2 and the width W2 of each coverage area may be any suitable dimension.
- Each sprinkler 14 of the preferred embodiments is connected to the supply line 12 and located along the supply line 12 such that the coverage areas of the sprinklers 14 overlap at least a significant portion of the space.
- Each sprinkler 14 is preferably oriented such that the length L2 of its coverage area extends in opposite directions toward the beams 16 and the width W2 of each coverage area extends to the two closest purlins 18. Locating the supply line 12 between the rafters 16 and orienting the sprinlders 14 towards the rafters 16 allows the fire sprinkler system 10 to be installed in a typically metal building with one-half of the supply lines of a conventional fire sprinkler system, which greatly reduces the labor and materials for the fire sprinkler system 10.
- the sprinkler 14 may be an upright-type sprinkler (above the supply line), a pendant-type sprinkler (below the supply line), or may alternatively be two horizontal-type sprinklers connected back-to-back.
- each sprinkler 14 is located along the supply line 12 between two purlins 18 such that each sprinlder 14 generally bisects the distance between either the two closest purlins 18 or the closest purlin 18 and a wall 20 or other structural member.
- each sprinlder 14 When the sprinkler 14 is located between two rafters 16 and between two purlins 18, it is generally centered within a volume 24 defined by a vertical extension of the rafters 16 on two sides, the purlins 18 on two sides, a first horizontal extension of the top of the purlins 18 (i.e., the roof 22) on one side, and finally a second horizontal extension of the bottom of the purlins 18.
- the hot "ceiling jets" that spread radially outward from a fire plume generally fills this volume 24.
