Description

Technology Field

[0001] The present invention relates to a fireproof cap with an embedded thermal insulation material, which is fastened to a pipe fixing device capable of fixing various pipes installed in a building, and which increases the convenience of installation of a thermal insulation material that is wrapped around a portion of the upper clamp of a pipe fixed to the pipe fixing device to prevent fire spread in the event of a fire in a lower floor, and prevents the thermal insulation material from unraveling. Background Technology

[0002] Generally, the interior space of a building is divided into multiple spaces by floors and walls, and mounting openings are formed in the building's framework, such as floors and walls, to allow various pipes to pass through. The mounting openings in the building framework are formed with a size larger than the width of the pipes, thereby enabling the pipes to pass through the openings even if there are design errors during installation.

[0003] However, as the mounting openings in the building frame are formed to be larger than the width of the pipes, gaps inevitably form between the building frame and the pipes during installation; these gaps become passageways for flames or smoke in the event of a fire, posing a problem of spreading fire-related damage.

[0004] To address these issues, it is currently legally mandated to seal mounting points in building frames with fire-resistant materials to prevent the spread of fire in the event of a fire. Various materials are used as fire-resistant materials to seal these mounting points for pipe installation. Recently, there has been an increasing use of pipe fixing devices combined with fire-resistant foam, which can fulfill the dual purposes of pipe installation and fire spread prevention.

[0005] Typically, a pipe fixing device combined with a fire-resistant foam includes a hollow through-sleeve inserted into a mounting hole of the building frame, a foamed fire-resistant foam coupled to the through-sleeve, and a fixing clamp coupled to the pipe to surround the pipe and coupled to the through-sleeve.

[0006] Here, the fixing clamp is installed and used in a form that not only comes into direct contact with the pipe made of metallic material but is also exposed to the outside.

[0007] In the event of a fire, such conventional pipe fixing devices can prevent flames from spreading from lower floors to upper floors by having the foamed fire-resistant foam expand due to the fire source and fill the gap between the penetrating sleeve and the metal pipe.

[0008] However, if the fire is not extinguished for an extended period, a situation arises where the metal piping located near the fire source is heated to a high temperature by the aforementioned fire source, and the metal piping extending toward the upper-floor unit space is also heated to a high temperature. Since this high-temperature heating of the metal piping extending toward the upper-floor unit space poses a problem in that it can act as another fire source capable of causing a separate fire in the upper-floor unit, a thermal insulation material was wrapped around the pipe at a certain height (the part where the temperature rises to a high temperature) above the clamp to suppress the temperature rise of the pipe.

[0009] In order to prevent heat from the heated metal pipe from being transferred to the surrounding space, conventionally, a thermal insulation material is installed on the top of the fixing clamp. A method was used in which a thermal insulation material having a certain thickness and width is wrapped around the metal pipe and the fixing clamp, and then the thermal insulation material is wrapped and fixed using thin PVC tape.

[0010] However, this construction method had a problem in that the PVC tape was easily torn and susceptible to heat, so after construction, the PVC tape would easily tear due to contact with foreign matter, causing the thermal insulation material to detach from the pipe, or in the event of a fire in the lower floor, heat would be directly transferred to the PVC tape through the gaps in the wound thermal insulation material, causing it to melt and unravel, making it impossible to expect the thermal insulation function.

[0011] Furthermore, this construction method involves a complex process that increases labor costs. Additionally, depending on the pressure applied when wrapping the PVC tape, the surface of the thermal insulation material can become uneven and bumpy, which can lead to heat being transferred to the pressured areas and detract from the external aesthetics. Prior art literature

[0012] Korean Patent Publication No. 10-1743932 (June 7, 2017) The problem to be solved

[0013] The present invention was devised to solve the aforementioned conventional problems, and aims to provide a fireproof cap with an embedded thermal insulation material that can solve the problems associated with PVC tape by not using PVC tape to wrap the thermal insulation material, by applying a new coupling structure between the pipe and the clamp without adopting the existing method of fixing the pipe and the clamp by wrapping them in a circumferential direction.

[0014] In addition, another objective of the present invention is to provide a fireproof cap with an integrated thermal insulation material that simplifies the overall operation and reduces construction costs compared to conventional methods.

[0015] In addition, another objective of the present invention is to provide a fireproof cap with an internal thermal insulation material that prevents the external exposure of the clamp after the entire piping construction work is completed, thereby preventing a deterioration of the overall aesthetics and providing the effect of improving aesthetics. means of solving the problem

[0016] According to one aspect of the present invention, a fireproof cap with an embedded heat-insulating material is provided, which is fastened to a pipe fixing clamp for fixing a pipe installed to pass through a mounting hole formed in a floor or wall between floors of a building, and is installed in a manner that surrounds a portion of the clamp in a circumferential direction together with the pipe that penetrates the clamp and is exposed above the clamp, and is structured to block the transfer of heat formed in the pipe to the surrounding space.

[0017] The above-mentioned fireproof cap may include a cap portion having a structure that surrounds a portion of the clamp in a circumferential direction, along with a portion of the pipe exposed above the clamp; and a thermal insulation material installed inside the cap portion.

[0018] The clamp includes a cover portion capable of covering the upper portion of the through sleeve and a pipe clamping portion connected to the cover portion so as to be in close contact with the outer surface of the pipe, and the lower portion of the cap portion and the lower portion of the thermal insulation material may be installed in a state of contact support with the upper surface of the cover portion.

[0019] The above pipe is a metal pipe, and the above cap part may be made of a plastic material with a relatively higher melting point compared to the above clamp.

[0020] The thermal insulation material can be installed in the cap portion so that it can directly contact the outer surface of the pipe while wrapping around the pipe in a circumferential direction.

[0021] The above cap portion is formed as a two-part structure in which a first cover cap member and a second cover cap member, each capable of partially covering the outer surface of the pipe and the clamp, are combined to completely surround the circumference of the pipe and the clamp, and the first cover cap member and the second cover cap member may be provided with a structure for one-touch joining to each other.

[0022] The cap portion further includes a third cover cap member formed with a step difference from the first cover cap member, having a cross-sectional area expanded compared to the first cover cap member while being integrally connected to the first cover cap member; and a fourth cover cap member formed with a step difference from the second cover cap member, having a cross-sectional area expanded compared to the second cover cap member while being integrally connected to the second cover cap member, wherein the lower ends of the third cover cap member and the fourth cover cap member are installed to be in contact with and supported on the upper surface of a concrete slab in which a penetration sleeve, provided to allow the pipe to pass through together with the clamp, is embedded, and the third cover cap member and the fourth cover cap member may be provided with a structure for one-touch coupling with each other.

[0023] The above cap portion includes a first cover cap member capable of covering one outer surface of the pipe and the clamp; a second cover cap member capable of covering the other outer surface of the pipe and the clamp; and a connecting portion connecting the first cover cap member and the second cover cap member, and the first cover cap member and the second cover cap member may be provided with a structure for one-touch coupling with each other.

[0024] The above connecting part may be a hinge, or may be made of the same material as the first cover cap member and the second cover cap member and be thinner than the thickness of the first cover cap member and the second cover cap member.

[0025] The cap portion further includes a third cover cap member formed with a step difference from the first cover cap member, having a cross-sectional area expanded compared to the first cover cap member while being integrally connected to the first cover cap member; and a fourth cover cap member formed with a step difference from the second cover cap member, having a cross-sectional area expanded compared to the second cover cap member while being integrally connected to the second cover cap member, wherein the lower ends of the third cover cap member and the fourth cover cap member are installed to be in contact with and supported on the upper surface of a concrete slab in which a penetration sleeve, provided to allow the pipe to pass through together with the clamp, is embedded, and the third cover cap member and the fourth cover cap member may be provided with a structure for one-touch coupling with each other. Effects of the invention

[0027] In addition, by not using the conventional PVC tape used to wrap the thermal insulation material, the problems that occur in the method of wrapping the thermal insulation material using PVC tape can be effectively resolved.

[0028] In addition, since a thermal insulation material is installed on the inside and a pair of cover cap members are combined to wrap around the piping in a circumferential direction and can be simply seated on the upper surface of the clamp, the worker can proceed with the construction work quickly and easily, and construction costs are also reduced.

[0029] In addition, by preventing the external exposure of the clamp after the entire piping installation work is completed, it is possible to prevent the deterioration of the overall aesthetics and provide the effect of improving the appearance. Brief explanation of the drawing

[0031] Hereinafter, embodiments of the present invention will be described in more detail with reference to the attached drawings. However, the present invention is not limited to the embodiments disclosed below but may be implemented in various different forms; these embodiments are provided merely to ensure that the disclosure of the present invention is complete and to fully inform those skilled in the art of the scope of the invention. Identical reference numerals in the drawings refer to identical elements.

[0032] A fireproof cap with an integrated thermal insulation material according to a preferred embodiment of the present invention is intended to prevent the spread of fire caused by high-temperature heat from a metal pipe, whose temperature has risen due to high-temperature heat generated during a fire, being transferred to the surrounding space and acting as another fire source. Overall, this simplifies the work, reduces construction costs, and minimizes the deterioration of aesthetics after construction is completed.

[0033] The present invention will be described in detail below with reference to examples.

[0034] As illustrated in FIGS. 1 to 4, a pipe fixing device (100) with a heat-insulating fireproof cap according to an embodiment of the present invention is for fixing a pipe (10) installed to pass through a mounting hole (21) formed on a floor or wall between floors of a building, and includes a through sleeve (110), a guide (140), a clamp (150), a fixing member (180), and a heat-insulating fireproof cap (200, hereinafter referred to as 'fireproof cap').

[0035] Here, the pipe (10) is a metal pipe such as a steel pipe or steel pipe, and provides a supply path for cold water, hot water, firefighting water, etc.

[0036] The through sleeve (110) is installed to be inserted into the mounting hole (21) and is formed with a hollow structure so that the pipe (10) can pass through it.

[0037] The guide (140) is rotatably coupled to the through sleeve (110) and is provided with a guide through hole (140a) through which the pipe (10) can pass inwardly.

[0038] The clamp (150) is formed to be coupled with the pipe (10) and supported by the guide (140). Additionally, the clamp (150) is coupled with the through sleeve (110), and an insertion opening (151) is provided so that the pipe (10) can pass through it, so that the clamp (150) is coupled with the pipe (10) while wrapping around it. A fixing member (180) is provided to fasten the clamp (150) to the through sleeve (110).

[0039] Additionally, the fireproof cap (200) is installed in a manner that wraps around a portion of the clamp (150) in a circumferential direction, along with the pipe (10) that penetrates the clamp (150) and is exposed above the clamp (150). Furthermore, the fireproof cap (200) is structured to block heat formed in the metal pipe (10) due to prolonged fire from being transferred to the surrounding space.

[0040] In an embodiment of the present invention, the pipe fixing device (100) is installed in the structural framework of a building, such as a floor or wall between floors, to provide a passage through which the pipe (10) can penetrate the floor or wall between floors of the building. In this embodiment, the pipe fixing device (100) is described as being installed in a mounting hole (21) formed in the floor (20) between floors of the building.

[0041] The penetration sleeve (110) is formed as a hollow structure having a sleeve penetration opening (111) through which a pipe (10) can pass. The penetration sleeve (110) is inserted into a mounting opening (21) of the floor (20) of a building. The penetration sleeve (110) includes a hollow base body (112) and a hollow connecting body (118) coupled to the upper part of the base body (112).

[0042] On the outer surface of the base body (112), a plurality of support portions (113) and fixing protrusions (115) are provided protruding outwardly. A coupling hole (114) is formed in the support portion (113) into which a fixing means, such as a nail or a screw, can be inserted. When assembling the through sleeve (110) to the formwork, the through sleeve (110) can be firmly fixed to the formwork by inserting a fixing means, such as a nail or a screw, into the coupling hole (114) and driving it into the formwork.

[0043] The support portion (113) and the fixing projection (115) are embedded in the concrete when concrete is poured into the formwork while the through sleeve (110) is fixed to the formwork, thereby increasing the bonding strength between the through sleeve (110) and the floor concrete slab (20) of the building.

[0044] As illustrated in FIG. 3, a fire-resistant foam insertion part (116) for installing a fire-resistant foam (130) is provided on the inner side of the through sleeve (110). The fire-resistant foam insertion part (116) is formed in the shape of a groove along the inner circumference of the base body (112) so that the end of the fire-resistant foam (130) can be inserted. The fire-resistant foam (130) can be simply connected to the through sleeve (110) by entering the interior of the base body (112) through one end of the base body (112) and fitting its end into the fire-resistant foam insertion part (116).

[0045] As illustrated in FIGS. 1 to 3, the connecting body (118) is coupled to the upper part of the base body (112), and a sleeve screw portion (119) for screw coupling with the guide (140) is provided on the inner side of the connecting body (118). A protruding rim portion (120) is provided protruding from the outer side of the connecting body (118). The protruding rim portion (120) increases the bonding force between the through sleeve (110) and the floor (20) of the building by being embedded in the concrete when concrete is poured into the formwork while the through sleeve (110) is fixed to the formwork.

[0046] In this way, the penetration sleeve (110) is equipped with a fire-resistant foam material (130) on its inner side, so that when a fire occurs, heat is easily transferred to the fire-resistant foam material (130), allowing the fire-resistant foam material (130) to expand quickly.

[0047] As illustrated in FIGS. 3 to 5, the guide (140) is formed as a hollow structure having a guide through hole (140a) through which a pipe (10) can pass inward. In an embodiment of the present invention, the guide (140) is provided with a guide projection (145) and an insertion hole (146). The insertion hole (146) is formed so that a fixing member (180) can be inserted.

[0048] As illustrated in FIGS. 1 to 5, the clamp (150) is provided with an insertion opening (151) through which the pipe (10) can pass inward, and is coupled to the pipe (10) while wrapping around the pipe (10), and is coupled to the guide (140) so as to be movably relative to the guide so that the center of the insertion opening (151) can be eccentric with respect to the center of the guide through-hole (140a).

[0049] As illustrated in FIGS. 1 to 5, the clamp (150) is provided with an insertion opening (151) through which the pipe (10) passes, so that it can be firmly connected to the pipe (10), and can be connected to a through sleeve (110) to support the pipe (10) so that the pipe (10) cannot move significantly.

[0050] Here, the clamp (150) is made of plastic material and comes into direct contact with the pipe (10), which has risen in temperature due to the high temperature generated during a fire. As a result, it may melt upon receiving this high temperature.

[0051] The clamp (150) includes a first clamp member (152) and a second clamp member (160). Each of the first clamp member (152) and the second clamp member (160) has one end hinged and the other end of each is separated from one another by a fixing mechanism so as to be able to wrap around the pipe (10).

[0052] The first clamp member (152) includes a first cover portion (153) capable of partially covering the upper portion of the through sleeve (110), and a first pipe tightening portion (154) provided in an arched shape corresponding to the outer surface of the pipe (10) on the inside of the first cover portion (153) so as to be in close contact with the outer surface of the pipe (10). A guide groove (155) into which a guide projection (145) can be inserted is formed in the middle of the first cover portion (153). The guide groove (155) is formed in the shape of an elongated groove extending perpendicularly to the longitudinal direction of the pipe (10) inserted into the insertion opening (151).

[0053] At one end of the first clamp member (152), a first hinge joint (156) for hinge connection with the second clamp member (160) is provided, and at the other end of the first clamp member (152), a fastening member (157) for connection with a fixing mechanism is formed.

[0054] The second clamp member (160) includes a second cover portion (161) that can partially cover the upper portion of the through sleeve (110), and a second pipe tightening portion (162) provided in an arched shape corresponding to the outer surface of the pipe (10) on the inside of the second cover portion (161) so as to be in close contact with the outer surface of the pipe (10). A guide groove (155) into which a guide projection (145) can be inserted is formed in the middle of the second cover portion (161).

[0055] At one end of the second clamp member (160), a second hinge joint (164) corresponding to the first hinge joint (156) of the first clamp member (152) is provided, and at the other end of the second clamp member (160), a fastener and a receiving portion (166) for connecting a fixing mechanism are provided. By connecting the second hinge joint (164) to the first hinge joint (156), the first clamp member (152) and the second clamp member (160) can be hinge-connected.

[0056] This clamp (150) can maintain a state of being firmly connected to the pipe (10) while being in close contact with the outer surface of the pipe (10) by fastening the other ends of the first clamp member (152) and the second clamp member (160) respectively with a fixing mechanism, such as a bolt and nut, while the first clamp member (152) and the second clamp member (160) are in contact with the outer surface of the pipe (10).

[0057] As illustrated in FIGS. 1 and 3, the fixing member (180) is for fastening the clamp (150) to the guide (140). The fixing member (180) is inserted into the insertion hole (146) of the guide (140) through the guide groove (155) on the outside of the clamp (150) to fix the clamp (150) to the guide (140).

[0058] Next, as illustrated in FIGS. 1 to 4, a fireproof cap (200) is provided to prevent the clamp (150) from being exposed to the outside along with a portion of the pipe (10). To this end, it is installed in a manner that wraps around a portion of the clamp (150) in a circumferential direction along with the pipe (10) that penetrates the clamp (150) and is exposed above the clamp (150).

[0059] Here, the fireproof cap (200) is structured to block heat formed in the pipe (10) from being transferred to the surrounding space.

[0060] To elaborate, if a fire that occurs in a lower-floor unit located relatively lower is not quickly extinguished in a short period of time, the pipe (10) made of metal material is heated to a high temperature, and the high temperature heat formed in the pipe (10) is transferred to the indoor space of the upper-floor unit, which can act as another factor in the spread of fire.

[0061] To prevent this, the present invention can block the transfer of high-temperature heat formed in the pipe (10) to the surrounding space by partially blocking the external exposure of the pipe (10) with a fireproof cap (200). Additionally, by making the fireproof cap (200) a heat-blocking structure equipped with a heat-insulating material, the transfer of high-temperature heat formed in the pipe (10) to the surrounding space can be blocked more stably.

[0062] Additionally, the heat insulation material (220) described later can primarily block the transfer of high-temperature heat formed in the pipe (10) to the surrounding space, and the cap portion (210) described later can secondarily block the transfer of heat that has passed through the heat insulation material (220) to the surrounding space.

[0063] As illustrated in FIGS. 1 to 4, the fireproof cap (200) includes a cap portion (210) and a heat-insulating material (220).

[0064] The cap portion (210) is made of a heat-insulating material and is structured to wrap around a portion of the clamp (150) in a circumferential direction, along with a portion of the pipe (10) exposed above the clamp (150).

[0065] Additionally, the thermal insulation material (220) is made of a heat-insulating material and is installed inside the cap portion (210). This thermal insulation material (220) may be applied as Cerakul, etc., but is not specifically limited.

[0066] As illustrated in FIG. 1, the cap portion (210) is provided with a thermal insulation material insertion portion (212) for installing a thermal insulation material (220). The thermal insulation material insertion portion (212) is formed in the shape of a groove along the inner circumference of the cap portion (210) so that the end (top) of the thermal insulation material (220) can be inserted and caught. The thermal insulation material (220) can be simply connected by entering the interior of the cap portion (210) through one end of the cap portion (210) and fitting its end into the thermal insulation material insertion portion (212).

[0067] In an embodiment of the present invention, as shown in FIGS. 1 to 4, a heat-insulating material (220) is installed in the heat-insulating material insertion part (212) of the cap part (210) so that the heat-insulating material (220) can directly contact the outer surface of the pipe (10) while wrapping around the pipe (10) in a circumferential direction.

[0068] In an embodiment of the present invention, the cap portion (210) is made of a plastic material, and it is more preferable to use a plastic material that has a relatively higher melting point than the clamp (150).

[0069] That is, as described above, even if a situation occurs where the pipe (10) is heated to a high temperature by fire heat and the clamp (150) in direct contact with the pipe (10) melts, the cap portion (210) does not melt and can reliably prevent the pipe (10) and the clamp (150) in the corresponding portion from being exposed to the outside.

[0070] Therefore, as described above, the high temperature heat formed in the pipe (10) due to the fire continuing for a long time can be more reliably blocked from being transferred to the surrounding space.

[0071] In an embodiment of the present invention, as shown in FIGS. 2 to 5, the bottom of the cap portion (210) and the bottom of the heat insulation material (220) are installed in a state of contact support with the upper surface of the first cover portion (153) and the second cover portion (161) of the clamp (150).

[0072] Accordingly, the present invention allows for a more convenient and rapid installation process when a worker installs the cap portion (210) to surround the pipe (10) while the heat insulation material (220) is mounted inside the cap portion (210), and the bottom of the cap portion (210) and the bottom of the heat insulation material (220) are simply seated and supported in contact with the upper surfaces of the first cover portion (153) and the second cover portion (161) of the clamp (150).

[0073] The present invention can block the transfer of high-temperature heat formed in the pipe (10) to the surrounding space by partially blocking the external exposure of the pipe (10) with a fireproof cap (200). Specifically, a heat-insulating material (220) can primarily block the transfer of high-temperature heat formed in the pipe (10) to the surrounding space, and a cap portion (210) can secondarily block the transfer of heat that has passed through the heat-insulating material (220) to the surrounding space. That is, the spread of fire to the surrounding space due to heat generated in the pipe (10) caused by the prolonged duration of the fire can be prevented more safely.

[0074] In addition, in an embodiment of the present invention, the fireproof cap (200) prevents external exposure of the clamp (10) when the entire piping construction work is completed, thereby preventing the overall aesthetic from deteriorating and providing the effect of improving the aesthetic.

[0075] In addition, the cap portion (210) is joined so as not to come into direct contact with the pipe (10), thereby preventing the situation in which the cap portion (210) melts due to the high temperature of the pipe (10) and the clamp (150) is exposed to the outside.

[0076] Hereinafter, various structures of the cap portion (210) of the heat-insulating refractory cap according to an embodiment of the present invention will be described.

[0077] For example, as illustrated in FIGS. 1 to 4, the cap portion (210) includes a first cover cap member (213) capable of covering one side of the outer surface of the pipe (10) and the clamp (150), and a second cover cap member (215) capable of covering the other side of the outer surface of the pipe (10) and the clamp (150).

[0078] That is, the cap portion (210) is formed as a two-part structure in which a first cover cap member (213) and a second cover cap member (215), each capable of partially covering the outer surface of the pipe (10) and the clamp (150), are combined to completely surround the circumference of the pipe (10) and the clamp (150).

[0079] In this way, if the cap portion (210) is made into a two-part structure including a first cover cap member (213) and a second cover cap member (215), it is advantageous to install the cap portion (210) to surround the pipe (10) and the clamp (150). In addition, the cap portion (210) of this structure is also advantageous for manufacturing.

[0080] As illustrated in FIGS. 1 and 2, the first cover cap member (213) and the second cover cap member (215) are provided with a structure for one-touch coupling with each other, for example, the first cover cap member (213) may be provided with a coupling projection (218), and the second cover cap member (215) may be provided with a coupling groove (219) to which the coupling projection (218) is coupled.

[0081] A plurality of connecting protrusions (218) may be provided at each end of the first cover cap member (213), and a plurality of connecting grooves (219) may likewise be provided at each end of the second cover cap member (215), and the operator can connect the first cover cap member (213) and the second cover cap member (215) by connecting the connecting protrusions (218) and the connecting grooves (219) in correspondence.

[0082] The operator can quickly and easily combine the first cover cap member (213) and the second cover cap member (215) by positioning a plurality of coupling protrusions (218) near each corresponding to a plurality of coupling grooves (219) and then performing a one-touch push to move the first cover cap member (213) and the second cover cap member (215) toward each other.

[0083] The coupling projection (218) and coupling groove (219) are described merely as examples, and it goes without saying that other coupling structures other than the coupling projection (218) and coupling groove (219) may be applied to the first cover cap member (213) and the second cover cap member (215) to enable one-touch coupling to each other.

[0084] As another example, as illustrated in FIGS. 6 and 7, the cap portion (210) includes a first cover cap member (213) capable of covering one side of the outer surface of the pipe (10) and the clamp (150), a second cover cap member (215) capable of covering the other side of the outer surface of the pipe (10) and the clamp (150), and a connecting portion (217) connecting the first cover cap member (213) and the second cover cap member (215).

[0085] That is, in the above description, the first cover cap member (213) and the second cover cap member (215) are structured to be completely separated from each other, but in FIG. 6 and FIG. 7, the first cover cap member (213) and the second cover cap member (215) are structured to be always connected through the connecting part (217).

[0086] In this case, there are advantages in terms of management, such as parts storage and inventory management, as well as in minimizing parts loss during on-site construction.

[0087] In this case as well, the first cover cap member (213) and the second cover cap member (215) are provided with a structure for one-touch joining to each other, and since such one-touch joining structure is the same as previously described, a redundant description is omitted.

[0088] In an embodiment of the present invention, the connecting part (217) is provided so that the second cover cap member (215) can freely hinge rotate with respect to the first cover cap member (213). The operator can deform the connecting part (217) to arrange the first cover cap member (213) and the second cover cap member (215) so that they surround the pipe (10) and the clamp (150), and then deform the connecting part (217) again and use a one-touch coupling structure to connect the first cover cap member (213) and the second cover cap member (215) to each other.

[0089] Here, as shown in FIG. 6, for example, the connecting part (217) can be applied as a hinge.

[0090] In addition, as illustrated in FIG. 7, as another example, the connecting portion (217) may be made of the same material as the first cover cap member (213) and the second cover cap member (215) and be thinner than the thickness of the first cover cap member (213) and the second cover cap member (215).

[0091] At this time, the first cover cap member (213), the second cover cap member (215), and the connecting part (217) can be made of the same plastic material and can be injection molded simultaneously to be formed integrally with each other.

[0092] Hereinafter, a fireproof cap with an integrated thermal insulation material according to another embodiment of the present invention will be described with reference to FIGS. 8 and 9.

[0093] Before explaining further, the refractory cap (300) according to another embodiment of the present invention has a modified structure of the cap portion (310) compared to the refractory cap (200) shown in FIGS. 1 and 2.

[0094] To elaborate, the cap portion (310) is similarly structured with a first cover cap member (213) and a second cover cap member (215). Additionally, the cap portion (310) may be structured with the first cover cap member (213) and the second cover cap member (215) separated from each other, or alternatively, as shown in FIGS. 6 and 7, they may be connected through a connecting portion (217).

[0095] However, as illustrated in FIG. 8 and FIG. 9, in another embodiment of the present invention, the cap portion (310) further includes a third cover cap member (331) and a fourth cover cap member (333).

[0096] The third cover cap member (331) is integrally connected to the first cover cap member (213) and is formed with a step difference from the first cover cap member (213) to have an expanded cross-sectional area compared to the first cover cap member (213). The third cover cap member (331) is integrally connected to the lower portion of the first cover cap member (213), and a step difference is formed at the connection portion with the first cover cap member (213).

[0097] Likewise, the fourth cover cap member (333) is integrally connected to the second cover cap member (215) and is formed with a step difference from the second cover cap member (215) to have an expanded cross-sectional area compared to the second cover cap member (215). The fourth cover cap member (333) is integrally connected to the lower portion of the second cover cap member (215), and a step difference is formed at the connection portion with the second cover cap member (215).

[0098] Here, the thermal insulation material (220) is provided in a state where it is filled in the inner side of the first cover cap member (213) and the third cover cap member (331), and in the inner side of the second cover cap member (215) and the fourth cover cap member (333), and is also positioned to contact the outer surface of the pipe (10).

[0099] In addition, the third cover cap member (331) and the fourth cover cap member (333) are provided with a structure for one-touch joining to each other at corresponding parts, similar to the first cover cap member (213) and the second cover cap member (215). Since this one-touch joining structure can be applied in the same way as described above, a redundant description is omitted.

[0100] In another embodiment of the present invention, as shown in FIG. 9, the lower ends of the third cover cap member (331) and the fourth cover cap member (333) are installed to be in contact with and supported on the upper surface of a concrete slab (20) in which a through sleeve (110) is installed to allow the pipe (10) to pass through together with a clamp (150).

[0101] That is, in FIG. 3, as the cap portion (210) is formed as a cylindrical structure having the same diameter, the lower ends of the first cover cap member (213) and the second cover cap member (215) are installed in a state of contact and support with the upper surface of the first cover portion (153) and the second cover portion (161) of the clamp (150), and accordingly, when all products are installed, the first cover portion (153) and the second cover portion (161) of the clamp (150) are inevitably exposed to the outside.

[0102] However, as shown in FIGS. 8 and 9, by applying the cap portion (310) in a structure including a first cover cap member (213), a second cover cap member (215), a third cover cap member (331), and a fourth cover cap member (333), and by ensuring that the lower ends of the third cover cap member (331) and the fourth cover cap member (333) are supported in contact with the upper surface of the concrete slab (20), the clamp (150) is not exposed to the outside when the installation is completed, thereby preventing aesthetic damage.

[0103] As shown in FIGS. 6 and 7, when a connecting portion (217) is provided, the connecting portion (217) is provided at the connection portion of the combination of the first cover cap member (213) and the third cover cap member (331), which are each integrally formed with each other, and the combination of the second cover cap member (215) and the fourth cover cap member (333).

[0104] Although the present invention has been illustrated and described above in relation to preferred embodiments for illustrating the principles of the invention, the invention is not limited to the configuration and operation as illustrated and described. Rather, those skilled in the art will understand that numerous changes and modifications to the invention are possible without departing from the spirit and scope of the appended claims.
