These and other aspects and implementations are discussed in detail below. The foregoing information and the following detailed description include illustrative examples of various aspects and implementations, and provide an overview or framework for understanding the nature and character of the claimed aspects and implementations. The drawings provide illustration and a further understanding of the various aspects and implementations, and are incorporated in and constitute a part of this specification.
The accompanying drawings are not intended to be drawn to scale. Like reference numbers and designations in the various drawings indicate like elements. For purposes of clarity, not every component can be labeled in every drawing. In the drawings:
Following below are more detailed descriptions of various concepts related to, and implementations of sprinkler boxes for embedded sprinkler pipe systems. Embedded sprinkler pipe systems can be embedded in building structures, such as ceilings. The various concepts introduced above and discussed in greater detail below can be implemented in any of numerous ways, including in prefabricated buildings.
Embedded sprinkler pipe systems can be provided in various installations, such as pre-fabricated installations. For example, ceilings or portions thereof can be pre-fabricated remotely from a building site, and then transported to the building site to manufacture the building. To provide a sprinkler through a concrete ceiling, a cavity may be made in the concrete, at the site or during pre-fabrication. However, these operations can affect the design of the concrete ceiling, or increase the size and weight of the pre-fabricated components by requiring the sprinkler piping to be included. The concrete work on a job site or at a factory at which the pre-fabrication process is performed may be performed relatively early in the building process, before the final building structure is determined, which can make it difficult to appropriately connect sprinkler systems through the ceiling. For example, false ceilings may be installed under the concrete ceiling to create space for lighting or concealed sprinklers, but such structures may not always be accounted for during earlier stages of the process.
Systems and methods as described herein can enable greater flexibility in where the sprinkler can be located, while reducing manufacturing and transportation costs, such as by avoiding the need to include piping in the pre-fabricated components, and allowing for sprinkler systems to be connected in a manner so that modifications to the ceiling or the locations of the sprinklers can be made at the job site after the initial pre-fabrication. For example, a sprinkler assembly (e.g., sprinkler box system) can include a pipe portion extending from an inlet end to an outlet end. The sprinkler assembly can include a stop coupled with the outlet end, the stop including a first wall and a second wall extending from the first wall, the first wall across the outlet end, the second wall contacting an inner surface of the pipe portion. The sprinkler assembly can include a plug coupled with the inlet end, the plug including a rim, a plug wall extending from the rim, and an end wall connected with the plug wall and opposite the rim, the plug wall contacting the inner surface of the pipe portion. The sprinkler box, including the pipe portion, can enable various types of fittings and pipe sizes to be coupled with the sprinkler system.
The pipe portion 104 can be sized to fit within a layer of the prefabricated assembly, while spacing the outlet end 116 and inlet end 112 appropriately. For example, the pipe portion 104 can define a height h along the pipe axis 108 and a diameter d (e.g., an outer diameter perpendicular to the pipe axis 108). The height h can be greater than or equal to 25 millimeters (mm) and less than or equal to 300 mm. The height h can be greater than or equal to 50 mm and less than or equal to 150 mm. The height h can be greater than or equal to 60 mm and less than or equal to 120 mm. The height h can be greater than or equal to 70 mm and less than or equal to 90 mm. The height h can be 77 mm. The diameter d can be greater than or equal to 20 mm and less than or equal to 300 mm. The diameter d can be greater than or equal to 40 mm and less than or equal to 120 mm. The diameter d can be greater than or equal to 50 mm and less than or equal to 100 mm. The diameter d can be 60 mm. The diameter d can be sized to be large enough to allow a variety of components, such as fittings and pipes of various sizes, to be located within the pipe portion. For example, as depicted in
The sprinkler assembly 100 can include a stop 120. The stop 120 can be coupled with the outlet end 116. The stop 120 can be made of a variety of materials, including but not limited to a resilient material (e.g., rubber), or a copolymer material, such as polyoxy-methylene (POM) acetal copolymer. The stop 120 can include a first wall 124 and a second wall 128 extending from the first wall 124. The second wall 128 can extend from a portion of the first wall 124 radially inward from an edge 132 of the first wall 124. The second wall 128 can be perpendicular or substantially perpendicular (e.g., at an angle greater than or equal to 85 degrees and less than or equal to 90 degrees, greater than or equal to 88 degrees and less than or equal to 92 degrees, greater than or equal to 89 degrees and less than or equal to 91 degrees) to the first wall 124. As such, when the stop 120 is received in the outlet end 116, the edge 132 can extend over a thickness of the pipe portion 104, while the second wall 128 fits against an inner surface of the pipe portion 104. The second wall 128 can have a length 1 that is a fraction of the height h, enabling the stop 120 to form sufficient contact with an inner surface of the pipe portion 104 to protect the pipe portion 104 while retaining ease of removal of the stop 120. The fraction can be less than one half.
The sprinkler assembly 100 can include a plug 136. The plug 136 can be coupled with the inlet end 112. The plug 136 and stop 120 can cooperate to seal an interior space of the pipe portion 104, which can protect the pipe portion 104 during assembly and transport. The plug 136 can be shaped to fit within the pipe portion 104. For example, the plug 136 can include a rim 140, a plug wall 144 extending from the rim 140 from a portion of the rim 140 inward from an edge of the rim 140. The plug 136 can include an end wall 148 connected with the plug wall 144 and opposite the rim 140. The end wall 148 can be sized to fit within the pipe portion 104. The plug 136 can be made of a resilient material, such as rubber, or a copolymer material, such as polyoxy-methylene (POM) acetal copolymer.
The sprinkler assembly 100 can include at least one divider 152. The divider 152 can be positioned within the pipe portion 104 to contact an inner surface of the pipe portion 104. The divider 152 can be between the plug 136 and the stop 120 (e.g., while the sprinkler assembly 100 is provided in the prefabricated assembly). The divider 152 can reduce a rate of heat transfer from a first side of the divider 152 (e.g., a side closer to the outlet end 116) to a second side of the divider 152 (e.g., a side closer to the inlet end 112). For example, the divider 152 can reduce a volume of air in the pipe portion 104 that is adjacent to the sprinkler connected with the outlet end 116 (e.g., sprinkler 904 described with reference to
Various components of the sprinkler assembly 100, including but not limited to the pipe portion 104, the stop 120, the plug 136, and the divider 152, can be made from materials with a heat transfer rate (e.g., thermal conductivity) selected to prevent such components from acting as a heat sink that may reduce the ability of a thermal trigger of the sprinkler to activate. For example, one or more such components can have a thermal conductivity greater than or equal to 0.1 W/(m-K) and less than or equal to 550 W/(m-K). The thermal conductivity can be as high as that of copper or silver.
The pipe fitting 204 can have a variety of form factors depending on the geometry of the system into which the pipe fitting 204 is to be installed, such as to connect the pipe fitting 204 with a horizontal layout of a piping system that the pipe fitting 204 is connected with to receive fluid. For example, as depicted in
The sprinkler fitting 200 can include a stop 208. The stop 208 can be similar to the stop 120. For example, the stop 208 can be sized to connect with the inlet end 112 (e.g., as depicted in
The sprinkler fitting 200 can include a plug 220. The plug 220 can be sized to seal an opening of the pipe fitting 204. The plug 220 can secure the stop 208 to the pipe fitting 204. The plug 220 can be made of a variety of materials (e.g., plastic, rubber, copolymers, polyoxy-methylene (POM) acetal copolymer).
The pipe 704 can be made from any of a variety of materials, including metal (e.g., copper, aluminum), plastic (e.g., PVC, CPVC), or combinations thereof. The pipe 704 can be a multi-layer pipe.
Pipe tape 708 can be wrapped around the pipe 704. The pipe tape 708 can be used to seal the pipe 704 and the sprinkler fitting 200, as well as to act as a resilient member around the pipe 704 to cushion the pipe 704 from impacts or strains from other materials.
The sprinkler 904 can operate in an open state and a closed state, and may normally operate in the closed state, such as by being biased to the closed state. The sprinkler 904 can be any of a variety of sprinklers, including but not limited to recessed, flush, institutional, or concealed sprinklers. The sprinkler 904 can switch to the open state in response to a fire condition, such as by being actuated to open when heated by a fire. The sprinkler 904 can include an inlet end 912 that connects with the at least one pipe 908, and extend from the inlet end 912 to an outlet end 916 at which a deflector 920 is disposed. The deflector 920 can include one or more tines shaped to direct flow of fluid that flows out of the sprinkler 904. The sprinkler 904 can include one or more frame arms 924 that extend from the inlet end 912 to the outlet end 916. The sprinkler 904 can include a thermal element (e.g., glass bulb, fuse) responsive to heat from the fire condition, causing the thermal element to break or otherwise fluidly couple the inlet end 912 with the outlet end 916. As such, the state 900 can be an installed state in which the sprinkler 904 is ready to operate.

At 1105, a sprinkler box assembly is provided. The sprinkler box assembly can be pre-fabricated, such as by being at least partially manufactured or assembled at a first location, and transported to a second location for installation. The sprinkler box assembly can include a sprinkler box coupled with a platform, and can include concrete (e.g., a first layer of concrete) adjacent to the sprinkler box and the platform. The sprinkler box can include a pipe portion extending from an outlet end adjacent to the platform to an inlet end, a stop at the outlet end and in contact with the platform, and a plug at the inlet end. Providing the sprinkler box assembly can include locating the sprinkler box assembly at a target location. The target location may correspond to a location at which a sprinkler is expected to be connected with a piping system via the pipe portion 104 (e.g., rather than being limited by the dimensions of the piping system).
At 1110, support materials are removed from the sprinkler box assembly. For example, the platform can be removed from under the sprinkler box. The stop and plug and be removed from the pipe portion. The support materials may be removed manually or through the use of various tools. As such, an assembly of the pipe portion and the concrete adjacent to the pipe portion can be provided in a manner ready for installation, such as to install a ceiling of a building and to connect the pipe portion with a fluid supply and with sprinkler components.
At 1115, a sprinkler fitting is mounted to the sprinkler box assembly. The sprinkler fitting can include a pipe fitting that can be used to connect with a piping system to provide fluid to a sprinkler, and a stop that can be positioned in the pipe portion to secure the sprinkler fitting to the pipe portion. Mounting the sprinkler fitting to the sprinkler box assembly can include positioning the stop in the pipe portion, such as to contact the stop and the pipe portion. The sprinkler fitting can include a plug that can plug an outlet end of the pipe fitting.
At 1120, one or more pipes can be connected with the sprinkler fitting. A pipe can be connected with an inlet end of the pipe fitting. The pipe can be made of any of a variety of materials, such as metal, plastic, or combinations thereof. The pipe can be a multi-layer pipe. The pipe can be connected with the sprinkler fitting by various processes, such as through a press fitting or threaded fitting. Pipe tape or pipe adhesives can be provided in the connection between the pipe and the pipe fitting of the sprinkler fitting to secure or seal the pipe and the pipe fitting. The pipe can be at least partially covered by pipe tape to provide sealing or resilience to the pipe.
At 1125, a second layer of concrete can be added to the sprinkler box assembly. For example, a concrete to form a second layer of concrete can be poured onto the first layer of concrete, the pipe, and sprinkler fitting, and the sprinkler box. The concrete can be added to form the second layer to a height above the pipe and sprinkler fitting. The concrete can be added subsequent to connecting the pipe with the sprinkler fitting.
At 1130, a sprinkler is connected with the sprinkler fitting. The sprinkler can be connected with the sprinkler fitting via one or more pipes. For example, an inlet end of a pipe section can be connected with the outlet end of the pipe fitting, so that the pipe section at least partially extends through the pipe portion of the sprinkler box. A length of the pipe section can be selected so that an outlet end of the pipe section is located within the pipe portion (e.g., above the outlet end of the pipe portion), which can facilitate located an inlet end of the sprinkler within the pipe portion (e.g., within the ceiling defined by the first layer of concrete). Various pipe components, such as pipe sections, bends (e.g., elbows of various angles), or junctions, may be provided between the sprinkler and the sprinkler fitting to position and orient the sprinkler in a desired position and orientation.
