Summary of the Invention
Problems to be Solved by the Invention
[0005] As shown in Patent Documents 1 and 2, there is a structure in which wiring materials such as electric wires and cables are provided to penetrate a partition through a penetration member such as a sleeve. In such a structure, in order to prevent the influence of a fire in the other area separated by the partition body from reaching the one area through the penetration member, a fireproof structure in which both ends of the penetration member are blocked and sealed to cause asphyxiation is applied.
[0006] However, for example, if the wiring members are haphazardly installed at the end of the penetration member, it becomes difficult to seal the end of the penetration member, making proper installation difficult.
[0007] This disclosure aims to solve the aforementioned problems and to provide a fire-resistant structure and method for compartment penetrations that enables proper construction. [Means for solving the problem]
[0008] To achieve the above-mentioned objectives, a fire-resistant partition penetration structure according to one aspect of the present disclosure includes a cylindrical penetrating member provided to penetrate one region and the other region partitioned by a partition body, and a closing portion that closes each end of the penetrating member, wherein the closing portion provided at least one end of the penetrating member includes a storage portion through which at least the one end of the penetrating member passes, and a heat-resistant sealing material stored in the storage portion in such a manner that it closes at least the one end of the penetrating member.
[0009] To achieve the above-mentioned objectives, a fire protection method for a partition penetration according to one aspect of the present disclosure is a fire protection method for a partition penetration, which involves closing each end of a cylindrical penetration member that penetrates one region and the other region partitioned by a partition body with a closing portion, the method comprising: providing a storage portion in the closing portion of at least one end of the penetration member through which at least one end of the penetration member passes; and storing a heat-resistant sealing material in the storage portion in such a manner that it closes at least one end of the penetration member. [Effects of the Invention]
[0010] This disclosure enables proper construction. [Brief explanation of the drawing]

[Figure 2] Figure 2 is a flowchart of the fire protection method for compartment penetrations according to the embodiment. [Figure 3] Figure 3 is a schematic diagram of another example of the fire protection structure for partition penetrations according to the embodiment. [Figure 4] Figure 4 is a schematic diagram of another example of the fire protection structure for partition penetrations according to the embodiment. [Figure 5] Figure 5 is a schematic diagram of another example of the fire protection structure for partition penetrations according to the embodiment. [Figure 6] Figure 6 is a schematic diagram of another example of the fire protection structure for partition penetrations according to the embodiment. [Modes for carrying out the invention]
[0012] Embodiments relating to this disclosure will be described in detail below with reference to the drawings. However, the present invention is not limited by these embodiments. Furthermore, some components in the embodiments described below are substituted or substantially identical to those easily substituted by those skilled in the art.
[0013] Figure 1 is a schematic diagram of the fire protection structure for a partition penetration according to the embodiment.
[0014] As shown in Figure 1, the fireproof structure for compartment penetrations is applied when a cable routing material 11 is installed through a compartment body 10 that divides a space into one area 10A and the other area 10B. The compartment body 10 is a robust plate made of reinforced concrete, including floor plates (ceiling plates) and wall plates. In Figure 1, the compartment body 10 is shown as a floor plate. The cable routing material 11 is mainly electric wires or cables, but may also be wires or the like. One area 10A is, for example, an equipment control room, and the other area 10B is, for example, a cable processing room.
[0015] The fire-resistant structure for a partition penetration in this embodiment includes a penetration member 1 and a closing portion 2.
[0016] The through member 1 is formed in a cylindrical shape from a metal pipe made of non-combustible material and is installed to penetrate the partition body 10. The through member 1 is inserted through a through hole 10C provided in the partition body 10 and fixed in place. When the through member 1 is fixed to the partition body 10, one end 1A leads to one region 10A partitioned by the partition body 10, and the other end 1B leads to the other region 10B partitioned by the partition body 10. Therefore, the through member 1 is fixed to the partition body 10 and is positioned to connect one region 10A and the other region 10B. A cable guide 11 is inserted through the through member 1, allowing the cable guide 11 to pass through one region 10A and the other region 10B. Note that although the cable guide 11 is shown as one in the figure, there may be multiple. Also, although the through member 1 is shown as one in the figure, there may be multiple.
[0017] The closure portion 2 closes each end 1A and 1B of the through member 1, respectively. The closure portion 2 includes one closure portion 2A that closes one end 1A of the through member 1, and the other closure portion 2B that closes the other end 1B of the through member 1. Details of the one closure portion 2A will be described later. The other closure portion 2B is filled into the other end 1B of the through member 1 and closes the gap between the inner circumferential surface of the through member 1 and the outer circumferential surface of the cable material 11. The other closure portion 2B is formed in a clay-like state and closes the gap between the inner circumferential surface of the through member 1 and the outer circumferential surface of the cable material 11 by hardening after being filled into the gap. The other closure portion 2B is a flame-retardant fire-resistant sealant that foams in the event of a fire, and is mainly composed of a carbon molding agent, a foaming agent, a flame-retardant dehydrating agent, a mineral oil-based binder, an inorganic filler, and flame-retardant reinforcing fibers.
[0018] One of the blocking parts 2A includes a storage part 2AA and a sealing material 2AB. The storage part 2AA communicates with one end 1A of the through member 1. The storage part 2AA shown in FIG. 1 is arranged within the thickness of the partition body 10 serving as a floor board. In the part of the partition body 10 where one end 1A of the through member 1 is fixed, a through hole 10C having an inner diameter larger than the outer diameter of the through member 1 is formed. Then, the storage part 2AA seals and closes the lower part of this through hole 10C with a bottom plate 2AAa made of a metal plate, and the inner peripheral surface of the through hole 10C is configured as a side wall 2AAb. Thus, the storage part 2AA is configured as a liquid-tight container. The one end 1A of the through member 1 penetrates and is fixed to the bottom plate 2AAa of the storage part 2AA. Therefore, the storage part 2AA is configured such that one end 1A of the through member 1 communicates with the one region 10A through the storage part 2AA arranged within the thickness of the partition body 10. Although not shown in the figure, the storage part 2AA may be configured as a liquid-tight container with a side plate made of a metal plate rising from the periphery of the bottom plate 2AAa as the side wall 2AAb, and this container may be fitted and arranged within the thickness of the partition body 10 so as to seal and close the through hole 10C having an inner diameter larger than the outer diameter of the through member 1.
[0019] The sealing material 2AB has heat resistance and is stored in the storage part 2AA in a manner of blocking one end 1A of the through member 1. The sealing material 2AB includes a first sealing material 2ABa and a second sealing material 2ABb. Both the first sealing material 2ABa and the second sealing material 2ABb have heat resistance. The first sealing material 2ABa is filled in one end 1A of the through member 1. The second sealing material 2ABb is arranged inside the storage part 2AA so as to cover the first sealing material 2ABa.
[0020] The first sealing material 2ABa and the second sealing material 2ABb are made of, for example, a material having fluidity, and the first sealing material 2ABa has lower fluidity (higher viscosity) than the second sealing material 2ABb. In other words, the first sealing material 2ABa and the second sealing material 2ABb are such that the second sealing material 2ABb has higher fluidity (lower viscosity) than the first sealing material 2ABa. In this case, the first sealing material 2ABa is a pouring type flame-retardant heat-resistant sealing material, and is composed mainly of an organic binder, a flame retardant, an inorganic filler, an additive, a curing agent, and the like. The first sealing material 2ABa is filled in one end portion 1A of the through member 1, and after entering the gap between the inner peripheral surface of the through member 1 and the outer peripheral surface of the wiring material 11, it cures to close the gap. Further, the second sealing material 2ABb is a pouring type flame-retardant heat-resistant sealing material, and is composed mainly of an organic binder, a flame retardant, an inorganic filler, an additive, a curing agent, and the like. The second sealing material 2ABb is stored inside the storage portion 2AA so as to cover the first sealing material 2ABa that closes one end portion 1A of the through member 1 and the wiring material 11 routed from one end portion 1A of the through member 1 to the inside of the storage portion 2AA, and after curing, it covers the portion. Since the second sealing material 2ABb has higher fluidity than the first sealing material 2ABa, it is in a liquid state before curing, and the liquid level is in a lowered state with respect to the boundary portion with the one region 10A that contacts the side wall 2AAb of the storage portion 2AA and the boundary portion with the one region 10A that contacts the wiring material 11 routed inside the storage portion 2AA, and this state remains even after curing. For example, the first sealing material 2ABa is used by mixing the main agent and the curing agent at a mixing ratio of 100:15, whereas the second sealing material 2ABb is used by mixing the main agent and the curing agent at a mixing ratio of 100:60.
[0021] In another configuration, the first sealant 2ABa is made of a foaming material, and the second sealant 2ABb is made of a fluid material. In this case, the first sealant 2ABa is filled into one end 1A of the through member 1, and fills the gap between the inner surface of the through member 1 and the outer surface of the cable routing material 11, and then hardens to seal the gap. The first sealant 2ABa can be made of a material mainly composed of urethane resin. The second sealant 2ABb is a pourable, flame-retardant, heat-resistant sealant, and is mainly composed of an organic binder, flame retardant, inorganic filler, additives, and hardener. The second sealant 2ABb covers the first sealant 2ABa that seals one end 1A of the through member 1, and the cable routing material 11 routed from one end 1A of the through member 1 into the storage section 2AA, by being stored inside the storage section 2AA and then hardening to cover the said portion. Because the second sealant 2ABb has higher fluidity than the first sealant 2ABa, it remains liquid before hardening. Due to surface tension, the liquid level drops at the boundary with one region 10A that contacts the side wall 2AAb of the reservoir 2AA, and at the boundary with one region 10A that contacts the wiring material 11 arranged inside the reservoir 2AA. This state persists even after hardening.
[0022] Figure 2 is a flowchart of the fire protection method for compartment penetrations according to the embodiment.
[0023] As shown in Figure 2, first, the through member 1 and the storage section 2AA are installed, and the cable guide 11 is passed through the through member 1 (step S1). Here, in step S1, the cable guide 11 is arranged in a complicated manner inside the storage section 2AA through which one end 1A of the through member 1 passes, at and around the position of that end 1A (see Figure 1). This tendency is stronger when there are multiple cable guides 11. After step S1, the other end 1B of the through member 1 is closed by the other closing section 2B (step S2). Also after step S1, one end 1A of the through member 1 is closed by one closing section 2A (steps S3-1, step S3-2). In step S3-1, the first sealing material 2ABa is filled into one end 1A of the through member 1. In step S3-1, the first sealant 2ABa is filled into one end 1A of the penetration member 1 using a long, slender tubular filling device, so as to allow access to one end 1A of the penetration member 1 while avoiding the intricately arranged wiring members 11. In step S3-2, the second sealant 2ABb is placed inside the storage section 2AA so as to cover the first sealant 2ABa. In this way, the fireproof structure for the compartment penetration is constructed.
[0024] In the above-described method for fire protection of compartment penetrations, step S2 and steps S3-1 and S3-2 may be performed in any order.
[0025] The fire-resistant structure for compartment penetrations configured in this way can seal and suffocate both ends 1A and 1B of the penetration member 1 so that the effects of a fire in the other area 10B separated by the compartment body 10 do not spread to the one area 10A through the penetration member 1.
[0026] Figures 3 to 6 are schematic diagrams of other examples of the fire protection structure for partition penetrations of the embodiment.
[0027] The fireproof structure for a compartment penetration shown in Figure 3 differs from the fireproof structure for a compartment penetration shown in Figure 1 in that one end 1A of the penetration member 1 penetrates the compartment body 10, which is a floor plate, and extends into one region 10A. In this case, the penetration member 1 is fixed to the compartment body 10 with the inner circumferential surface of the through hole 10C and its own outer circumferential surface sealed without gaps by mortar. A one-sided closure portion 2A is provided at one end 1A of the penetration member 1. The one-sided closure portion 2A includes a storage portion 2AA and a sealing material 2AB, similar to the configuration shown in Figure 1. The storage portion 2AA is configured as a pull box and is a liquid-tight container with a bottom plate 2AAa made of metal plate and side plates 2AAb made of metal plate rising from the periphery of the bottom plate 2AAa. The one end 1A of the penetration member 1 penetrates and fixes this storage portion 2AA to the bottom plate 2AAa. Therefore, the storage section 2AA is constructed such that one end 1A of the through member 1 passes through its liquid-tight container. The one end 1A of the through member 1 then connects to one region 10A via the storage section 2AA. The sealing material 2AB includes a first sealing material 2ABa and a second sealing material 2ABb, similar to the configuration shown in Figure 1. The first sealing material 2ABa and the second sealing material 2ABb are similar to the configuration shown in Figure 1, and their configuration and fire prevention method will be omitted. In addition, the other end 1B of the through member 1 is provided with the other closing section 2B, similar to the configuration shown in Figure 1. The other closing section 2B is similar to the configuration shown in Figure 1, and its configuration and fire prevention method will be omitted.
[0028] The fireproof structure for a compartment penetration shown in Figure 4 is configured such that the compartment body 10 is a wall panel. In this fireproof structure for a compartment penetration, one end 1A of the penetration member 1 penetrates the compartment body 10 and leads to one region 10A. The penetration member 1 is fixed to the compartment body 10 with the inner circumferential surface of the through hole 10C and its own outer circumferential surface sealed without gaps by mortar. One closing portion 2A is provided at one end 1A of the penetration member 1. The closing portion 2A includes a storage portion 2AA and a sealing material 2AB, similar to the configuration shown in Figure 1. The storage portion 2AA is configured as a pull box and is a liquid-tight container with a bottom plate 2AAa made of metal plate and side plates 2AAb made of metal plate rising from the periphery of the bottom plate 2AAa. In this storage section 2AA, a portion of the side wall 2AAb is fixed to the plate surface on one side of region 10A of the partition body 10, and one end 1A of the penetrating member 1 is fixed through the side wall 2AAb. Therefore, the storage section 2AA is configured such that one end 1A of the penetrating member 1 passes through its liquid-tight container. The one end 1A of the penetrating member 1 then connects to the one side of region 10A via the storage section 2AA. The sealing material 2AB includes a first sealing material 2ABa and a second sealing material 2ABb, similar to the configuration shown in Figure 1. The first sealing material 2ABa and the second sealing material 2ABb are similar to the configuration shown in Figure 1, and their configuration and fire prevention method will be omitted. In addition, the other end 1B of the penetrating member 1 is provided with the other closing section 2B, similar to the configuration shown in Figure 1. The other closing section 2B is similar to the configuration shown in Figure 1, and its configuration and fire prevention method will be omitted.
[0029] The fireproof structure for a compartment penetration shown in Figure 5 differs from the fireproof structure for a compartment penetration shown in Figure 4 in that one end 1A of the penetration member 1 penetrates a compartment body 10 which is a wall plate and extends into one region 10A. A one-sided closing section 2A is provided at one end 1A of this penetration member 1. The one-sided closing section 2A includes a storage section 2AA and a sealing material 2AB, similar to the configuration shown in Figure 1. The storage section 2AA is configured as a pull box and is a liquid-tight container with a bottom plate 2AAa made of metal and side plates 2AAb made of metal that rise from the periphery of the bottom plate 2AAa. The one end 1A of the penetration member 1 penetrates and fixes this storage section 2AA to the bottom plate 2AAa. Therefore, the storage section 2AA is configured with one end 1A of the penetration member 1 passing through its liquid-tight container. One end 1A of the through member 1 leads to one region 10A via the storage portion 2AA. The sealing material 2AB includes a first sealing material 2ABa and a second sealing material 2ABb, similar to the configuration shown in Figure 1. The first sealing material 2ABa and the second sealing material 2ABb are similar to the configuration shown in Figure 1, and their configuration and fire prevention method will be omitted. In addition, the other end 1B of the through member 1 is provided with the other closing portion 2B, similar to the configuration shown in Figure 1. The other closing portion 2B is similar to the configuration shown in Figure 1, and its configuration and fire prevention method will be omitted.
[0030] The fireproof structure for a compartment penetration shown in Figure 6 is constructed with a compartment body 10 as a wall panel. In this fireproof structure for a compartment penetration, a penetration member 1 is buried underground and penetrates the lower part of the compartment body 10, with one end 1A reaching one area 10A and the other end 1B reaching the other area 10B. The penetration member 1 shown in Figure 6 is made of an Eflex pipe made of heat-resistant and fire-resistant material. In one area 10A, one end 1A of the penetration member 1 is fixed to and communicates with a handhole 3 provided underground. Similarly, in the other area 10B, the other end 1B of the penetration member 1 is fixed to and communicates with a handhole 3 provided underground. One of the closing sections 2A is provided at one end 1A of the penetration member 1. The closing section 2A includes a storage section 2AA made of a concrete handhole 3 and a sealing material 2AB. The storage section 2AA is constructed as a liquid-tight container by a bottom plate 2AAa and a side wall 2AAb that rises from the periphery of the bottom plate 2AAa. One end 1A of the penetrating member 1 is fixed to the side wall 2AAb of the storage section 2AA by passing through it. Therefore, the storage section 2AA is constructed so that one end 1A of the penetrating member 1 passes through its liquid-tight container. The one end 1A of the penetrating member 1 then passes through the storage section 2AA to one region 10A. The sealing material 2AB includes a first sealing material 2ABa and a second sealing material 2ABb, similar to the configuration shown in Figure 1. The first sealing material 2ABa and the second sealing material 2ABb are similar to the configuration shown in Figure 1, and their configuration and fire prevention method will be omitted. In addition, the other end 1B of the penetrating member 1 is provided with the other closing section 2B, similar to the configuration shown in Figure 1. The other closed section 2B has the same configuration as shown in Figure 1, and therefore, an explanation of its configuration and fire prevention method will be omitted.
[0031] In the embodiment described above, one of the closing portions 2A is provided at one end 1A of the through member 1, but it may also be provided at the other end 1B of the through member 1 instead of the other closing portion 2B.
[0032] Thus, the fireproof structure for a partition penetration of the embodiment includes a cylindrical penetrating member 1 that penetrates one region 10A and the other region 10B partitioned by a partition body 10, and closing portions 2A and 2B that close both ends 1A and 1B of the penetrating member 1, wherein one closing portion 2A provided at least one end 1A of the penetrating member 1 includes a storage portion 2AA through which at least one end 1A of the penetrating member 1 passes, and a heat-resistant sealing material 2AB stored in the storage portion 2AA in a manner that closes at least one end 1A of the penetrating member 1.
[0033] According to this fire-resistant structure for partition penetrations, by storing a heat-resistant sealant 2AB in the storage section 2AA through which at least one end 1A of the penetration member 1 passes, the penetration member 1 can be properly sealed without any gaps by the sealant 2AB. As a result, proper construction can be carried out.
[0034] Furthermore, in the fire-resistant structure for partition penetrations of the embodiment, the sealing material 2AB includes a first sealing material 2ABa that is filled into at least one end 1A of the penetration member 1, and a second sealing material 2ABb that is stored in the storage section 2AA so as to cover the first sealing material 2ABa.
[0035] According to this fireproof structure for partition penetrations, the first sealing material 2ABa closes at least one end 1A of the penetration member 1, and the second sealing material 2ABb covers the first sealing material 2ABa and is stored in the storage section 2AA, thereby reliably sealing the penetration member 1.
[0036] Furthermore, in the fire-resistant structure for partition penetrations of the embodiment, the first sealing material 2ABa and the second sealing material 2ABb are made of a fluid material, and the first sealing material 2ABa has lower fluidity than the second sealing material 2ABb.
[0037] This fireproof structure for partition penetrations allows for a more reliable sealing of the penetration member 1 by using a first sealant 2ABa with low fluidity to remain inside the penetration member 1, and then using a second sealant 2ABb with high fluidity to completely cover the first sealant 2ABa and store it in the storage section 2AA without any gaps.
[0038] Furthermore, in the fire-resistant structure for partition penetrations of the embodiment, the first sealing material 2ABa is made of a foaming material, and the second sealing material 2ABb is made of a fluid material.
[0039] According to this fireproof structure for partition penetrations, the penetration member 1 can be sealed more reliably by using a foamed first sealant 2ABa to remain inside the penetration member 1 and then using a fluid second sealant 2ABb to cover the first sealant 2ABa without any gaps and store it in the storage section 2AA.
[0040] Furthermore, in the fire-resistant structure for the partition penetration of the embodiment, the cable routing material 11 is inserted through the penetration member 1, and the sealing material 2AB closes the gap between the penetration member 1 and the cable routing material 11.
[0041] This fire-resistant structure for compartment penetrations is particularly useful in configurations where a cable guide 11 is inserted through a penetration member 1, and allows for proper construction that closes the gap between the penetration member 1 and the cable guide 11.
[0042] Furthermore, the fire protection method for partition penetrations of the embodiment is a fire protection method for partition penetrations in which each end 1A, 1B of a cylindrical penetration member 1 that penetrates one region 10A and the other region 10B partitioned by a partition body 10 is closed by closing portions 2A, 2B, and includes the steps of providing a storage portion 2AA through which at least one end 1A of the penetration member 1 passes in the closing portion 2A of at least one end 1A of the penetration member 1, and storing a heat-resistant sealing material 2AB in the storage portion 2AA in a manner that closes at least one end 1A of the penetration member 1.
[0043] According to this fire protection method for partition penetrations, by storing a heat-resistant sealant 2AB in a storage section 2AA through which at least one end 1A of the penetration member 1 passes, the penetration member 1 can be properly sealed without any gaps by the sealant 2AB. As a result, proper construction can be carried out.
[0044] Furthermore, in the fire protection method for partition penetrations of the embodiment, the step of storing the sealing material 2AB includes the step of filling at least one end 1A of the penetration member 1 with the first sealing material 2ABa, and the step of arranging the second sealing material 1ABb in the storage portion 2AA so as to cover the first sealing material 2ABa.
[0045] According to this fire protection method for partition penetrations, the first sealing material 2ABa closes at least one end 1A of the penetration member 1, and the second sealing material 2ABb covers the first sealing material 2ABa and is stored in the storage section 2AA, thereby reliably sealing the penetration member 1.
[0046] Furthermore, in the fire protection method for partition penetrations of the embodiment, the first sealing material 2ABa and the second sealing material 2ABb are made of a fluid material, and the first sealing material 2ABa has lower fluidity than the second sealing material 2ABb.
[0047] According to this fire protection method for partition penetrations, the penetration member 1 can be sealed more reliably by using a first sealant 2ABa with low fluidity to remain inside the penetration member 1 and then using a second sealant 2ABb with high fluidity to cover the first sealant 2ABa and store it in the storage section 2AA without any gaps.
[0048] Furthermore, in the fire protection method for partition penetrations of the embodiment, the first sealing material 2ABa is made of a foaming material, and the second sealing material 2ABb is made of a fluid material.
[0049] According to this fire protection method for partition penetrations, the penetration member 1 can be sealed more reliably by sealing it with a foamed first sealant 2ABa so that it remains inside the penetration member 1, and then storing the fluid second sealant 2ABb in the storage section 2AA so that it completely covers the first sealant 2ABa without any gaps.
