Description

Technical Field

[0001] This invention relates to a fire-stopping device, particularly an embedded fire-stopping device for use in buildings. More specifically, the embedded fire-stopping device of this invention includes means for removing and installing replaceable internal fire-resistant components. Background Technology

[0002] With the development of construction technology, building quality standards have become more stringent, with particular emphasis on energy efficiency and safety. The pipelines embedded in buildings, including water pipes, electrical wires, and gas pipelines, are subject to the most stringent safety regulations, as electricity and gas are the most likely sources of fire. Once ignited, the fire and smoke can easily travel through the pipelines and permeate the building's interior spaces, rather than being confined to a specific area.

[0003] To prevent the spread of fire from pipelines, fire suppression devices are frequently used in the installation of pipelines. For example, known fire suppression devices can be embedded in building structures such as floors and walls. Depending on the construction method or type of the floors and walls, fire suppression devices with different installation methods have been developed to suit various construction methods. For example, walls can be broadly categorized into concrete walls, wet-grouted walls, and dry-type lightweight partition walls. If the building's pipelines pass through walls of more than one type, appropriate fire suppression devices must be used for each type. This is inconvenient for construction workers.

[0004] In addition, since most fire suppression devices are embedded in walls or floors, it is not easy to replace fireproof components with limited lifespans or those affected by humidity. This reduces the willingness to replace them, preventing the fire suppression devices from achieving their best effect and sacrificing building safety.

[0005] Therefore, it is necessary to develop fire-stopping devices that allow for easy replacement of internal fire-resistant components without damaging the building structure itself, and are suitable for use with various types of walls or floors. Summary of the Invention

[0006] The present invention aims to provide an embedded fire-stopping device, comprising: a fixing plate having a contact surface for contacting a building structure and a first connecting member located on the contact surface; a container having an opening side and a second connecting member located on the opening side; and a fireproof member housed in the container. The first connecting member and the second connecting member are configured to be detachably connected, allowing the fixing plate and the container to be joined and separated.

[0007] In one specific embodiment, the first connecting member has a plurality of grooves and the second connecting member has a plurality of protrusions, the grooves and the protrusions being able to engage with each other, the grooves defining a sliding path for the corresponding protrusions, the sliding path having two different directions.

[0008] In one specific embodiment, the connection is an engaging or locking connection.

[0009] Another object of the present invention is to provide an embedded fire-stopping device, comprising: a fixing plate having a contact surface for contacting a building body and a first connecting member located on the contact surface; a container having an opening side and a second connecting member located on the opening side; and a fireproof member housed in the container. The first connecting member has a connecting surface with a plurality of grooves, each of the grooves having a first limiting region and a second limiting region. The second connecting member has a plurality of protrusions, each of the protrusions being able to pass through the first limiting region of a corresponding groove along a first direction, and each of the protrusions being able to pass through the second limiting region of a corresponding groove along a second direction, the first direction being different from the second direction, thereby allowing the grooves and protrusions to be detachably connected, enabling the fixing plate and the container to be joined and separated.

[0010] In one specific embodiment, the first limiting region restricts the corresponding protrusion from moving along the second direction, and the second limiting region restricts the corresponding protrusion from moving along the first direction, wherein the size of the first limiting region is larger than the size of the second limiting region, and wherein the connection is an engagement.

[0011] Another object of the present invention is to provide a method for using the above-described embedded fire-stopping device, particularly when the embedded fire-stopping device is embedded in a building structure (such as a wall or floor). The method includes: separating the embedded fire-stopping device from an opening in the building structure; separating the container from the mounting plate to expose a fire-resistant component located within the container; replacing the fire-resistant component; connecting the mounting plate and the container; and placing the container into the opening in the building structure.

[0012] In one specific embodiment, the container is separated from the fixed disk by a reverse rotation operation.

[0013] Another object of the present invention is to provide a mounting plate for an embedded fire-stopping device, comprising: a contact surface for contacting a building body and a first connecting member located on the contact surface, wherein the first connecting member is configured to be detachably connected to a second connecting member of a container located in the building body, the container accommodating a fire-resistant component.

[0014] In one specific embodiment, the detachable means includes the first connecting member having a plurality of grooves.

[0015] In one specific embodiment, these grooves define a sliding path for the connection, which has two different directions.

[0016] These and other features and advantages of the invention will be presented in more detail in the following description of the invention and in the accompanying drawings illustrated by the principles of the invention. Attached Figure Description

However, the subject matter of this claim can be embodied in many different forms, and therefore the construction of the claimed subject matter is not limited to any of the exemplary embodiments disclosed in this specification; the exemplary embodiments are merely illustrative. Similarly, the invention aims to provide a reasonably broad scope for the claimed or covered subject matter. Furthermore, the claimed subject matter can be embodied, for example, as a method, apparatus, or system. Therefore, embodiments can take the form of, for example, hardware, software, firmware, or any combination thereof (known not to be software).

[0024] The term "in one embodiment" as used in this specification does not necessarily refer to the same specific embodiment, and the term "in other (some / certain) embodiments" as used in this specification does not necessarily refer to different specific embodiments. The purpose is to, for example, include combinations of all or some of the exemplary embodiments. The term "embedded" as used in this specification refers to a state in which the fire-stopping device has at least a portion embedded, inserted, extended into, or concealed within the building structure, but without preventing the fire-stopping device from being separated from the building structure. Preferably, the "embedded" state includes the fire-stopping device being flush with the surface of the building structure.

[0025] Figure 1 and Figure 2 These are perspective views of the assembled and unassembled embedded fire-extinguishing device 10 of the present invention. The fire-extinguishing device 10 includes a fixing plate 11, a container 12, and a fireproof component 13.

[0026] The mounting plate 11 is a plate body having a front surface 111 and a contact surface 112 opposite to the front surface 111. The contact surface 112 is the area where the embedded fire-stopping device 10 contacts the wall surface. That is, during installation, the contact surface 112 faces the wall. The contact surface 112 also provides a first connecting member (shown in...). Figure 3A (Middle). The fixing plate 11 has an opening 113, the size of which can be appropriately selected to conform to the diameter of the tube. In one embodiment, the fixing plate 11 may be provided with a resilient sleeve 114 extending from the opening 113 toward one side of the contact surface 112, such as Figure 2 As shown. Alternatively, the elastic sleeve 114 can be replaced with a structure consisting of multiple tongues or silicone sheets. Accordingly, the tube can be elastically held in the opening 113. The fixing plate 11 may or may not have holes. For ease of installation, the fixing plate 11 preferably has multiple holes 115, which can be used with known fixing means (such as screws) to fix the fixing plate 11 to the wall surface.

[0027] Figure 3A A first connecting component of the fixed disk 11 is shown for connecting the container 12. In this embodiment, the first connecting component is an annular connecting component 116, which is located on the contact surface 112 of the fixed disk 11 and conforms to... Figure 1The dimensions of the opening 113 are shown. The annular connecting member 116 has a connecting surface 117, which serves as the main contact portion during connection. During connection, the connecting surface 117 is flat and opposite to the inner surface of the container 12. In other embodiments, the connecting surface may be different from the connecting surface 117 shown in the figure, for example, it may be a plane of the annular connecting member 116 or an opposing inner annular surface. The connecting surface 117 also forms one or more grooves 118, allowing the annular connecting member 116 to be detachably connected to the container 12. Detachable connection as described herein refers to a selective connection method that allows the two components to be connected and separated, such as engagement with a specific structure or connection with a well-known locking means. The embodiment described herein is primarily illustrated with slidable engagement. The groove 118 is recessed inward from the connecting surface 117 and has a first limiting region 1181 and a second limiting region 1182. The first limiting region 1181 and the second limiting region 1182 have different dimensions. As shown in the figure, the first limiting region 1181 extends longitudinally from the contact surface 112 to the top surface 119 of the annular connecting member 116, while the second limiting region 1182 also extends longitudinally from the contact surface 112 but does not reach the top surface 119. The purpose of the groove 118 will be explained later.

[0028] Container 12 is cylindrical and has two open sides 121 and 122, such as Figure 2 As shown. The size of container 12 can be selected so that container 12 can be appropriately matched with the size of the first connecting part and tube of fixed plate 11. The open side 121 is located on this side of contact surface 112, and the other open side 122 is at the far end of embedded fire-stopping device 10. The front open side 121 of container 12 is configured to slidably engage and disengage from contact surface 112 of fixed plate 11. Figure 2 The container 12 has a second connecting member on its open side 121, which engages with a first connecting member of the retaining disc 11, namely the annular connecting member 116. In this embodiment, the second connecting member is a plurality of protrusions 123. These protrusions 123 extend from the inner side 124 of the container 12 toward a common center (not shown). If the container 12 is metal, the protrusions 123 may be formed by slightly bending the edge of the container 12. If the container 12 is plastic, the protrusions 123 may be integrally formed with the structure of the cylinder.

[0029] Figure 2 The protrusions 123 and Figure 3AThe grooves 118 engage with each other, allowing the fixing plate 11 and the container 12 to be joined and separated. The size of the first limiting region 1181 matches the size of the protrusion 123, and the first limiting region 1181 restricts the protrusion 123 to move only along the first direction A. The size of the second limiting region 1182 matches the size of the protrusion 123, but the second limiting region 1182 restricts the protrusion 123 to move only along the second direction B. Alternatively, the first limiting region 1181 restricts the protrusion 123 from moving along the second direction B, while the second limiting region 1182 restricts the protrusion 123 from moving along the first direction A. As shown, the first direction A and the second direction B are generally perpendicular to each other. However, in other possible embodiments, depending on the design of the grooves, the first and second directions are not perpendicular.

[0030] Figures 3A to 3B The process of engaging the first connecting part of the fixed disk 11 with the second connecting part of the container 12 is illustrated. The front opening side 121 of the container 12 approaches the contact surface 112 of the fixed disk 11 with protrusions 123 corresponding to grooves 118, until each protrusion 123 slides into and passes through the first limiting region 1181 of the corresponding groove 118, finally stopping at the contact surface 112. This constitutes the first step of the engagement of the fixed disk 11 and the container 12. The protrusions 123 can only slide along a first direction A within the first limiting region 1181, causing the fixed disk 11 and the container 12 to move closer or further apart. When the protrusions 123 are at the end of the first limiting region 118, the container 12 can be rotated to allow the protrusions 123 to slide into and pass through a second limiting region 1182 along a second direction B, as the second part of the engagement of the fixed disk 11 and the container 12. Figure 3B As shown. The protrusion 123 can only slide along the second direction B within the second restrictive region 1182 until it is fully within the second restrictive region 1182, causing the protrusion 123 and the groove 118 to engage. The second restrictive region 1182 prevents the protrusion 123 from sliding along the first direction A, thus preventing the fixing disc 11 and the container 12 from separating. Similarly, the fixing disc 11 and the container 12 can be separated by the reverse operation.

[0031] The groove 118 and protrusion 123 can provide detailed structures to enhance the engagement between the two and prevent accidental loosening of the connection. In another embodiment, the groove 118 and protrusion 123 can be arranged in opposite directions, that is, the groove 118 can be formed on the second connecting member of the container 12, while the protrusion 123 can be provided on the first connecting member of the retaining plate 11. In other embodiments, such as when the container size is smaller than the annular connecting member, i.e., the outer side of the container 12 faces the inner side of the annular connecting member 116, the groove 118 can be formed on the inner side of the annular connecting member 116, while the protrusion 123 is provided on the outer side of the container 12. Although these modifications are not detailed in the accompanying drawings, those skilled in the art should be able to implement them based on the above description.

[0032] refer to Figure 2 The size and shape of the fire-resistant component 13 can be selected so that it can be accommodated within the container 12 without affecting the pipe configuration. For example, the fire-resistant component 13 can be molded into a sheet or ring shape. The material of the fire-resistant component 13 can be selected from known fire-resistant materials, such as preheated expanding foam with smoke-blocking effects, which can fill the space of the pipeline to block the transmission of fire and smoke. As previously described, when the mounting plate 11 is combined with the container 12, the fire-resistant component 13 is housed between the two. Figure 2 Elastic sleeve 114 or Figure 3A The annular connecting member 116 may have a suitable longitudinal extension to prevent the housed fire-resistant component 13 from falling into the space of the pipe configuration or being exposed to the opening 113 of the device. Similarly, other restraining components may be provided within the container 12 to facilitate the positioning of the fire-resistant component 13. By separating the retaining plate 11 and the container 12, the fire-resistant component 13 can be removed from the opening side 121 of the container 12 and other fire-resistant components can be inserted. Through the above two steps, the replacement of the embedded fire-stopping device 10 is completed.

[0033] Figures 4A to 4B This is a schematic diagram of installing the embedded fire-stopping device 10 of the present invention onto a wall 30. The wall is not limited to a single construction method. Whether it is a concrete wall, a wet-grouted wall, or a dry lightweight partition wall, as long as a perforation is formed during or after construction, the embedded fire-stopping device 10 of the present invention can be applied. Before inserting the pipe into the perforation, the embedded fire-stopping device 10 of appropriate size is fixed to both sides of the perforation, such as... Figure 4A As shown. As previously described, the mounting plate 11 is placed so that the contact surface 112 contacts the wall surface, and the mounting plate 11 is fixed to the wall surface with screws, while the container 12 is received in the perforation. Next, the tube is inserted into the perforation through the opening 113 of the embedded fire-stopping device 10 and out through the opening 113 of the other opposite embedded fire-stopping device 10, completing the pipeline configuration, as shown. Figure 4BIt should be understood that the embedded fire-stopping device 10 is structured to separate the pipe from the wall 30, i.e., there is a gap between the embedded portion of the pipe and the wall, which can be used to fill other fire-resistant components. The embedded fire-stopping device 10, located on both sides of the wall 30, provides fire suppression, preventing the spread of fire and smoke to other compartments. To inspect or replace the embedded fire-stopping device, the device 10 can be removed from the wall without removing the pipe. The removed embedded fire-stopping device 10 can be further disassembled to separate the mounting plate 11 and the container 12, exposing the housed fire-resistant component 13. In a possible embodiment, the size of the mounting plate 11 may be close to or slightly smaller than the diameter of the perforation, allowing the embedded fire-stopping device 10 to be placed deeper within the perforation.

[0034] Figure 5 The flowchart for replacing the fireproof component 13 in the embedded fire-stopping device 10 includes steps S500 to S504. The situation discussed here refers to a building structure such as a floor slab or wall, which is equipped with the embedded fire-stopping device of the present invention, such as... Figure 4B As shown. In step S500, the embedded fire-stopping device 10 is detached from the building structure. For example, the mounting plate 11 of the embedded fire-stopping device 10 can be detached from the building structure with or without tools (such as locking tools), allowing the embedded fire-stopping device 10 to be removed from the building structure. In step S501, the container 12 is detached from the mounting plate 11 to expose the fireproof component 13 to be replaced located inside the container 12. In one specific embodiment, where the two are slidably engaged as described above, the mounting plate 11 and the container 12 can be separated by rotating them in opposite directions with both hands. In step S502, the fireproof component is replaced. In step S503, the mounting plate 11 and the container 12 are reconnected. In step S504, the container 12 is inserted into the hole in the building structure, completing the replacement of the fireproof component. In another embodiment, the order of steps S503 and S504 can be interchanged. The replacement can be performed with or without conduits in the building structure.

[0035] In summary, the embedded fire-stopping device of this invention is applicable to various types of walls and even floors. Furthermore, because the embedded fire-stopping device is installed externally on the wall, it can be disassembled without damaging the wall's structure or existing piping, and the fire-resistant components inside can be easily inspected. Therefore, the embedded fire-stopping device of this invention provides builders with more flexible options.

[0036] While the invention has been described in certain details for clarity, it will be understood that specific changes and modifications may be made within the scope of the claims. Therefore, the above embodiments are for illustrative purposes only and are not intended to be limiting, and the invention is not limited to the details described herein, but modifications may be made within the scope of the appended claims and their equivalents.
