Description

Technical Field

[0001] The present invention relates to an attachment structure for the upper end portion of a fire-resistant panel, and more particularly, to an attachment structure for the upper end portion of a fire-resistant panel forming a fire-resistant partition wall.

Background Art

[0002] A partition wall formed by connecting a plurality of panels in the width direction is known. Patent Document 1 discloses a connection portion structure of fire-resistant panels when a plurality of fire-resistant panels are connected to form a fire-resistant partition wall. As shown in Patent Document 1 (FIG. 2), usually, the upper end portion of a fire-resistant panel is fixed to a ceiling portion (for example, concrete) with screws.

[0003] However, when a beam is located directly above the installation location of the fire-resistant panel, driving screws directly into the beam means drilling holes in the structural beam and must be avoided. Therefore, when attaching the upper end portion of the fire-resistant panel to the beam, a device is required, and it is important that the attachment structure takes into account the workability of attaching the fire-resistant panel.

[0004] Also, in the fire-resistant panel constituting the fire-resistant partition wall, it is important to suppress heat transfer from the fire side (heating surface side) to the non-fire side (non-heating surface side) as much as possible.

[0015] As shown in Figure 1, the fire-resistant partition wall according to this embodiment is formed from a plurality of fire-resistant panels 1 connected in the width direction. The fire-resistant partition wall is installed to enclose the space formed by the left and right side walls W, the ceiling (steel beam 2), and the floor surface FL. The width direction of the fire-resistant panel 1 coincides with the length direction of the steel beam 2, and the upper end of each fire-resistant panel 1 extends along the steel beam 2 and is attached to the steel beam 2. The lower end of each fire-resistant panel 1 is attached to the floor surface FL. In the illustrated embodiment, a partition wall is formed by connecting four fire-resistant panels 1, and the fire-resistant panels 1 located on the left and right are attached to the left and right side walls W via insulation material 18. For details on the connection configuration between the fire-resistant panels 1, refer to the disclosures in Patent Document 1, for example.

[0016] As shown in Figure 2, the fire-resistant panel 1 comprises a first surface material forming a first surface portion 10, a second surface material forming a second surface portion 11, and a fire-resistant core material 12 filled in the space between the first surface portion 10 and the second surface portion 11. The upper end surface 13 of the fire-resistant panel 1 is formed from the upper ends of the first and second surface materials and the upper end surface of the fire-resistant core material 12. The lower end surface 14 of the fire-resistant panel 1 is formed from the lower ends of the first and second surface materials and the lower end surface of the fire-resistant core material 12. In this embodiment, the first and second surface materials of the fire-resistant panel 1 are formed from steel plates, and rock wool can be exemplified as the fire-resistant core material 12.

[0017] The steel beam 2 according to this embodiment is made of H-shaped steel, and in the figures (Figures 2, 4, 6, and 7), the lower portion of the vertical section 20 and the horizontal section 21 at the lower end of the vertical section 20 are shown, while the upper portion of the I-shaped steel is omitted. The lower surface 210 of the horizontal section 21 at the lower end of the steel beam 2 is the lower surface of the steel beam 2, and a plurality of attachment elements 3 are fixed (for example, welded) to the lower surface 210 at intervals in the longitudinal direction (opening width direction) of the steel beam 2 (see Figure 5).

[0018] The mounting element 3 is a short steel element, and as shown in Figure 8, the mounting element 3 consists of a rectangular lower surface portion 30 in plan view, a pair of vertical sides 31 rising opposite each other from both longitudinal ends of the lower surface portion 30, and a pair of upper sides 32 formed by bending at the upper ends of the pair of vertical sides 31. The longitudinal direction of the lower surface portion 30 is aligned with the longitudinal direction of the steel beam 2, and the pair of upper sides 32 are welded to the lower surface 210 of the steel beam 2, so that it protrudes downward from the lower surface 210 of the steel beam 2.

[0019] The steel beam 2 is wrapped with a fire-resistant coating material 22, and the lower surface 210 of the steel beam 2 is covered with the fire-resistant coating material 22. In other words, the steel beam 2 according to this embodiment is a beam with a fire-resistant coating material, and substantially the lower surface 220 of the fire-resistant coating material 22 is the lower surface of the steel beam 2. The hollow part of the mounting element 3 is filled with fire-resistant material 33. In this embodiment, the fire-resistant coating material 22 and the fire-resistant material 33 are made from the same material. The mounting element 3, which protrudes from the lower surface 210 of the steel beam 2, has its upper portion embedded in the fire-resistant coating material 22, and its lower portion, including the lower surface portion 30 of the lower end, is located below the lower surface 220 of the fire-resistant coating material 22 (see Figures 2, 3, and 5).

[0020] As shown in Figures 2 and 3, the lower surface 30 of the element to be mounted 3 is connected to the first intermediate mounting element 4 and the second intermediate mounting element 5 by screws S1 and S2, respectively, at a distance from each other in the depth direction of the fire-resistant panel 1. The first intermediate mounting element 4 and the second intermediate mounting element 5 are long steel elements extending in the width direction of the fire-resistant panel 1. In the configuration shown in Figures 2 and 3, the lower surface 30 of the element to be mounted 3 and the first intermediate mounting element 4 and the second intermediate mounting element 5 are spaced apart and connected by screws S1 and S2 with an insulating material 15 interposed between them. The lower surface 30 of the element to be mounted 3 and the first intermediate mounting element 4 are not in direct contact, and the lower surface 30 of the element to be mounted 3 and the second intermediate mounting element 5 are not in direct contact.

[0021] More specifically, as shown in Figure 3, the first intermediate mounting element 4 has a cross-sectional L-shape with a first horizontal side (upper side) 40 and a first vertical side 41 hanging down from the first horizontal side (upper side) 40. The first horizontal side (upper side) 40 is spaced apart and opposite to the first side portion of the lower surface portion 30 of the mounting element 3, and these are connected by a screw S1 with an insulating material 15 interposed between them. The first vertical side 41 of the first intermediate mounting element 4 is flush with the first surface portion 10 of the fire-resistant panel 1. The first vertical side 41 of the first intermediate mounting element 4 is low in height, and the lower end of the first vertical side 41 is located above the upper surface 13 of the fire-resistant panel 1.

[0022] The second intermediate mounting element 5 has a cross-sectional L-shape, consisting of a second horizontal side (upper side) 50 and a second vertical side 51 hanging down from the second horizontal side (upper side) 50. The second horizontal side (upper side) 50 is spaced apart and opposite to the second side portion of the lower surface portion 30 of the mounting element 3, and these are connected by a screw S2 with an insulating material 15 interposed between them. The first vertical side 51 of the second intermediate mounting element 5 is flush with the second surface portion 11 of the fire-resistant panel 1. The second vertical side 51 of the second intermediate mounting element 5 is low in height, and the lower end of the second vertical side 51 is located above the upper surface 13 of the fire-resistant panel 1.

[0023] A heat insulating material 15 is provided between the first horizontal side (upper side) 40 of the first intermediate mounting element 4 and the second horizontal side (upper side) 50 of the second intermediate mounting element 5 and the lower surface portion 30 of the element to be mounted 3. Furthermore, the tip of the first horizontal side (upper side) 40 of the first intermediate mounting element 4 and the tip of the second horizontal side (upper side) 50 of the second intermediate mounting element 5 are separated and not in contact, so that direct heat transfer does not occur between the first intermediate mounting element 4 and the second intermediate mounting element 5.

[0024] The first intermediate mounting element 4 is connected to the first fixing element 6. The first fixing element 6 is a long steel element that extends in the width direction of the fire-resistant panel 1. As shown in Figure 3, the first fixing element 6 has a cross-sectional L shape with a first upper side 60 and a first vertical side 61 hanging down from the first upper side 60. With the first upper side 60 in contact with the lower surface 220 of the fire-resistant coated beam 2, the first vertical side 61 (the part above the upper end surface 13 of the fire-resistant panel 1) is in contact with the first vertical side 41 of the first intermediate mounting element 4 and connected with a screw S3. The first vertical side 61 of the first fixing element 6 (the part below the upper end surface 13 of the fire-resistant panel 1) is in contact with the upper part of the first surface 10 of the fire-resistant panel 1 and connected with a screw S5.

[0025] The second intermediate mounting element 5 is connected to the second fixing element 7. The second fixing element 7 is a long steel element that extends in the width direction of the fire-resistant panel 1. As shown in Figure 3, the second fixing element 7 has a cross-sectional L-shape with a first upper side 70 and a first vertical side 71 hanging down from the first upper side 70. With the first upper side 70 in contact with the lower surface 220 of the fire-resistant coated beam 2, the first vertical side 71 (the part above the upper end surface 13 of the fire-resistant panel 1) is in contact with the first vertical side 51 of the second intermediate mounting element 5 and connected with a screw S7. The second vertical side 71 of the second fixing element 7 (the part below the upper end surface 13 of the fire-resistant panel 1) is in contact with the upper part of the second surface 11 of the fire-resistant panel 1 and connected with a screw S8.

[0026] As described above, the first vertical side 41 of the first intermediate mounting element 4 and the second vertical side 51 of the second intermediate mounting element 5 are both low in height, and the lower ends of the first vertical side 41 and the second vertical side 51 are located above the upper end surface 13 of the fire-resistant panel 1. Therefore, the first intermediate mounting element 4 and the second intermediate mounting element 5 do not get in the way when installing them at the upper end of the fire-resistant panel 1.

[0027] In this embodiment, the space or gap formed in the area enclosed by the upper end surface 13 of the fire-resistant panel 1, the lower surface 220 of the steel beam, the first vertical side 61 of the first fixing element 6, and the second vertical side 71 of the second fixing element 7 is filled with thermal insulation material 16 across the width direction of the fire-resistant panel 1 (see Figures 3 and 5).

[0028] As shown in Figures 4 and 5, in the enclosed area where the mounting element 3 is not provided, the space formed in the area enclosed by the upper end surface 13 of the fire-resistant panel 1, the lower surface 220 of the steel beam, the first vertical side 61 of the first fixing element 6, and the second vertical side 71 of the second fixing element 7 is divided into an upper space on the lower surface 220 side of the steel beam and a lower space on the upper end surface 13 side of the fire-resistant panel 1 by the first horizontal side (upper side) 40 of the first intermediate mounting element 4 and the second horizontal side (upper side) 50 of the second intermediate mounting element 5, and insulation material 16 is filled into both the upper and lower spaces.

[0029] As shown in Figures 3 and 5, in the enclosed area where the mounting element 3 is located, the space formed in the area enclosed by the upper end surface 13 of the fire-resistant panel 1, the lower surface 220 of the steel beam, the first vertical side 61 of the first fixing element 6, and the second vertical side 71 of the second fixing element 7 is divided by the first horizontal side (upper side) 40 of the first intermediate mounting element 4 and the second horizontal side (upper side) 50 of the second intermediate mounting element 5 into an upper space on the lower surface 220 side of the steel beam and a lower space on the upper end surface 13 side of the fire-resistant panel 1. Furthermore, the upper space is divided into The mounting element 3, which occupies the central part, forms a lower gap between the lower surface 30 of the mounting element 3 and the first horizontal side (upper side) 40 of the first intermediate mounting element 4 and the second horizontal side (upper side) 50 of the second intermediate mounting element 5, a lateral gap between the side surface 34 of the mounting element 3, which is filled with fire-resistant material 33, and the first vertical side 61 of the first fixing element 6, and a lateral gap between the side surface 34 of the mounting element 3, which is filled with fire-resistant material 33, and the first vertical side 71 of the second fixing element 7. The lower gap is filled with thermal insulation material 15, and the lateral gaps are filled with thermal insulation material 16.

[0030] As shown in Figure 2, the lower end portion of the fire-resistant panel 1 is attached to the floor surface FL by a first lower fixing element 8 and a second lower fixing element 9. An insulating material 17 is filled between the lower end surface 14 of the fire-resistant panel 1 and the floor surface FL.

[0031] The first lower fixing element 8 is a long steel element extending in the width direction of the fire-resistant panel 1. As shown in Figure 2, the first lower fixing element 8 has a cross-sectional L-shape with a first lower edge 80 and a first vertical edge 81 rising vertically from the first lower edge 80. The first lower edge 80 is attached with screws S4 while in contact with the floor surface FL, and the first vertical edge 81 of the first lower fixing element 8 is connected with screws S6 while in contact with the lower part of the first surface 10 of the fire-resistant panel 1 so as to overlap with it.

[0032] The second lower fixing element 9 is a long steel element extending in the width direction of the fire-resistant panel 1. As shown in Figure 2, the second lower fixing element 9 has a cross-sectional L-shape with a second lower edge 90 and a second vertical edge 91 that rises vertically from the second lower edge 90. The second lower edge 90 is attached with screws S9 in contact with the floor surface FL, and the second vertical edge 91 of the second lower fixing element 9 is connected with screws S10 in contact with the lower part of the second surface 11 of the fire-resistant panel 1 so as to overlap with it.

[0033] The thermal insulation materials 15, 16, 17, and 18 according to this embodiment are made of bio-soluble fibers used as fire-resistant thermal insulation materials, but the specific material of the thermal insulation material is not limited thereto. For example, the thermal insulation material 15 located between the lower surface 30 of the mounting element 3 and the first horizontal side (upper side) 40 of the first intermediate mounting element 4 and the second horizontal side (upper side) 50 of the second intermediate mounting element 5 may be formed from calcium silicate board, gypsum board, or the like.

[0034] The installation process for the fire-resistant panel 1 according to this embodiment will now be described. Please refer to Figure 2 as appropriate. (1) Prepare the mounting element 3 and fix it to a predetermined location along the length of the lower surface 210 of the steel beam 2. At this time, the hollow part of the mounting element 3 is filled with fire-resistant material 33, and the fire-resistant covering material 22 is wrapped around the steel beam 2. The steel beam 2 is a beam with fire-resistant covering material, and the lower surface 220 of the fire-resistant covering material 22 is the lower surface of the steel beam 2. The lower surface portion 30 of the mounting element 3 is located below the lower surface 220 of the steel beam 2.

[0035] (2) Prepare the first intermediate mounting element 4 and attach the first horizontal side (upper side) 40 of the first intermediate mounting element 4 to the first side portion of the lower surface portion 30 of the element to be mounted 3 with a screw S1, but at this time the first horizontal side (upper side) 40 and the lower surface portion 30 of the element to be mounted 3 are spaced apart and the insulating material 15 is sandwiched between the first horizontal side (upper side) 40 and the lower surface portion 30 to fix them in place. Prepare the second intermediate mounting element 5 and attach the second horizontal side (upper side) 50 of the second intermediate mounting element 5 to the second side portion of the lower surface portion 30 of the element to be mounted 3 with a screw S2, but at this time the first horizontal side (upper side) 50 and the lower surface portion 30 of the element to be mounted 3 are spaced apart and the insulating material 15 is sandwiched between the second horizontal side (upper side) 50 and the lower surface portion 30 to fix them in place.

[0036] (3) With the first upper side 60 of the first fixing element 6 in contact with the lower surface 220 of the steel beam 2, the first vertical side 61 is fixed to the first vertical side 41 of the first intermediate mounting element 4 with screws S3. At this stage, the insulation material 15 and insulation material 16 may be partially filled.

[0037] (4) Prepare the first lower fixing element 8 and fix the first lower edge 80 to a predetermined position on the floor surface FL with screws S4. The first vertical edge 61 of the first fixing element 6 and the first vertical edge 81 of the first lower fixing element 8 are located on the same vertical plane. At this stage, the insulation material 17 may be placed on the floor surface FL. Alternatively, the insulation material 17 may be pre-bonded to the lower end surface 14 of the fire-resistant panel 1.

[0038] (5) Prepare the fire-resistant panel 1, and fix the upper part of the first surface portion 10 to the first vertical side 61 of the first fixing element 6 with a screw S5, and fix the lower part of the first surface portion 11 to the first vertical side 81 of the first lower fixing element 8 with a screw S6. At this stage, fill the space or gap between the upper end surface 13 and the lower surface 220 of the fire-resistant panel 1 with the heat insulating material 15 and heat insulating material 16. If the heat insulating material 15 and heat insulating material 16 have already been partially filled, the remaining space or gap may be filled with the heat insulating material 15 and heat insulating material 16.

[0039] (6) The second surface portion 11 of the fire-resistant panel 1 and the second vertical side 51 of the second intermediate mounting element 5 are located on the same vertical plane. With the second upper side 70 of the second fixing element 7 in contact with the lower surface 220 of the steel beam 2, the second vertical side 71 is brought into contact with the second vertical side 51 of the second intermediate mounting element 5 and the upper portion of the second surface portion 11 of the fire-resistant panel 1, respectively, and fixed with screws S7 and S8.

[0040] (7) Prepare the second lower fixing element 9, fix the second lower edge 90 to a predetermined position on the floor surface FL with screws S9, and fix the second vertical edge 91 to the lower part of the second surface 11 of the fire-resistant panel 1 with screws S10.

[0041] As described above, the mounting structure for the upper end portion of the fire-resistant panel according to this embodiment comprises a fire-resistant panel 1 having a first surface portion 10 and a second surface portion 11, a mounting element 3 projecting downward from the lower surface 210 (220) of the steel beam, a first intermediate mounting element 4 and a second intermediate mounting element 5 connected to the mounting element 3 at a distance from each other, a first fixing element 6 connected to the first intermediate mounting element 4, and a second fixing element 7 connected to the second intermediate mounting element 5, wherein the upper portion of the first surface portion 10 is connected to the first fixing element 6 and the upper portion of the second surface portion 11 is connected to the second fixing element 7, the first intermediate mounting element 4 and the mounting element 3 are connected by screws S1 with a heat insulating material 15 interposed between them, and the second intermediate mounting element 5 and the mounting element 3 are connected by screws S2 with a heat insulating material 15 interposed between them. Since there is no contact between continuous metal surfaces between the first surface 10 and the second surface 11 of the fire-resistant panel 1, heat transfer from the fire side (heated surface side) to the non-fire side (non-heated surface side) can be suppressed as much as possible in the fire-resistant panel 1 that constitutes the fire-resistant partition wall.

[0042] In the configuration shown in Figure 6, compared to the configuration shown in Figure 3, the first vertical side 41 of the first intermediate mounting element 4 is taller, and the first vertical side 61 of the first fixing element 6 is shorter. The lower end of the first vertical side 41 is located below the upper end surface 13 of the fire-resistant panel 1, and the first vertical side 41 abuts against the upper part of the first surface portion 10 of the fire-resistant panel 1 and is fixed with a screw S5. The lower end of the first vertical side 61 of the first fixing element 6 is located above the upper end surface 13 of the fire-resistant panel 1, and the first vertical side 61 is fixed to the upper part of the first vertical side 41 with a screw S3. The other configurations are the same as in the configuration shown in Figure 3, with the first intermediate mounting element 4 and the element to be mounted 3 connected by a screw S1 with an insulating material 15 interposed between them, and the second intermediate mounting element 5 and the element to be mounted 3 connected by a screw S2 with an insulating material 15 interposed between them. Since there is no contact between continuous metal surfaces between the first surface 10 and the second surface 11 of the fire-resistant panel 1, heat transfer from the fire side (heated surface side) to the non-fire side (non-heated surface side) can be suppressed as much as possible in the fire-resistant panel 1 that constitutes the fire-resistant partition wall. Although the lower end of the first vertical side 41 of the first intermediate mounting element 4 is located below the upper end surface 13 of the fire-resistant panel 1, this does not interfere with the installation process of the fire-resistant panel 1 as described above.

[0043] In other configurations not shown, instead of the thermal insulation material 15 (in this configuration, the first intermediate mounting element 4 and the second intermediate mounting element 5 may be directly fixed to the element to be mounted 3), or in addition, the first vertical side 61 of the first fixing element 6 and the first vertical side 41 of the first intermediate mounting element 4 may be interposed with thermal insulation material and connected with screws, and the second vertical side 71 of the second fixing element 7 and the second vertical side 51 of the second intermediate mounting element 5 may be interposed with thermal insulation material and connected with screws. In this configuration as well, since there is no contact between continuous metal surfaces between the first surface 10 and the second surface 11 of the fire-resistant panel 1, heat transfer from the fire side (heated surface side) to the non-fire side (non-heated surface side) can be suppressed as much as possible in the fire-resistant panel 1 that constitutes the fire-resistant partition wall.

[0044] In the embodiment shown in Figure 7, the mounting element 3 is divided into a first mounting element 3A on the first side and a second mounting element 3B on the second side, with the first mounting element 3A and the second mounting element 3B spaced apart. The first intermediate mounting element 4 is fixed to the first mounting element 3A, and the second intermediate mounting element 5 is fixed to the second mounting element 3B. In this embodiment, since the first mounting element 3A and the second mounting element 3B are spaced apart, there is no contact between continuous metal surfaces between the first surface 10 and the second surface 11 of the fire-resistant panel 1. Therefore, in the fire-resistant panel 1 that constitutes the fire-resistant partition wall, heat transfer from the fire side (heated surface side) to the non-fire side (non-heated surface side) can be suppressed as much as possible.

[0045] Further embodiments will be described with reference to Figure 9. Figure 9 is similar to Figure 6, but shows another embodiment of the second intermediate mounting element 5. As shown in Figure 9, the mounting structure for the upper end of the fire-resistant panel according to this embodiment consists of a fire-resistant panel 1 having a first surface portion 10 and a second surface portion 11, a mounting element 3 projecting downward from the lower surface 210 (220) of the steel beam, a first intermediate mounting element 4 and a second intermediate mounting element 5 connected to the mounting element 3 at a distance from each other, a first fixing element 6 connected to the first intermediate mounting element 4, and a second fixing element 7 connected to the second intermediate mounting element 5. The upper part of the first surface portion 10 is connected to the first intermediate mounting element 4, and the upper part of the second surface portion 11 is connected to the second fixing element 7. The first intermediate mounting element 4 and the element to be mounted 3 are connected by a screw S1 with an insulating material 15 interposed between them, and the second intermediate mounting element 5 and the element to be mounted 3 are connected by a screw S2 with an insulating material 15 interposed between them.

[0046] The first intermediate mounting element 4 has a cross-sectional L-shape with a first horizontal side 40 and a first vertical side 41 hanging down from the first horizontal side 40. The first horizontal side 40 is spaced apart and opposite to the first side portion of the lower surface portion 30 of the mounting element 3, and is connected by a screw S1 with an insulating material 15 interposed between them. The lower end of the first vertical side 41 is located below the upper end surface 13 of the fire-resistant panel 1, and the first vertical side 41 abuts against the upper portion of the first surface portion 10 of the fire-resistant panel 1 and is fixed by a screw S5.

[0047] The second intermediate mounting element 5 has an L-shape in cross-section, consisting of a second horizontal side 50 and a second vertical side 51' that rises vertically from the second horizontal side 50. The second horizontal side 50 is spaced apart and opposite to the second side portion of the lower surface portion 30 of the mounting element 3, and these are connected by a screw S2 with an insulating material 15 interposed between them. The second vertical side 51' of the second intermediate mounting element 5 is flush with the second surface portion 11 of the fire-resistant panel 1.

[0048] The first intermediate mounting element 4 is connected to the first fixing element 6. The first fixing element 6 has a cross-sectional L-shape with a first upper side 60 and a first vertical side 61 hanging down from the first upper side 60. With the first upper side 60 in contact with the lower surface 220 of the fire-resistant coated beam 2, the lower end of the first vertical side 61 of the first fixing element 6 is located above the upper surface 13 of the fire-resistant panel 1, and the first vertical side 61 is fixed to the upper part of the first vertical side 41 with a screw S3.

[0049] The second intermediate mounting element 5 is connected to the second fixing element 7. The second fixing element 7 has a cross-sectional L-shape with a first upper side 70 and a first vertical side 71 hanging down from the first upper side 70. With the first upper side 70 in contact with the lower surface 220 of the fire-resistant coated beam 2, the first vertical side 71 (the part above the upper end surface 13 of the fire-resistant panel 1) is in contact with the first vertical side 51' of the second intermediate mounting element 5 and connected with a screw S7. The second vertical side 71 of the second fixing element 7 (the part below the upper end surface 13 of the fire-resistant panel 1) is in contact with the upper part of the second surface 11 of the fire-resistant panel 1 and connected with a screw S8.

[0050] The first horizontal side 40 of the first intermediate mounting element 4 and the second horizontal side 50 of the second intermediate mounting element 5 are located at the same height and are spaced apart from the lower surface 30 of the element to be mounted 3. An insulating material 15 is provided between the first horizontal side 40 of the first intermediate mounting element 4, the second horizontal side 50 of the second intermediate mounting element 5, and the lower surface 30 of the element to be mounted 3. Furthermore, the tip of the first horizontal side 40 of the first intermediate mounting element 4 and the tip of the second horizontal side 50 of the second intermediate mounting element 5 are spaced apart and not in contact, so that direct heat transfer does not occur between the first intermediate mounting element 4 and the second intermediate mounting element 5. Since there is no contact between continuous metal surfaces between the first surface 10 and the second surface 11 of the fire-resistant panel 1, heat transfer from the fire side (heated surface side) to the non-fire side (non-heated surface side) can be suppressed as much as possible in the fire-resistant panel 1 that constitutes the fire-resistant partition wall.

[0051] The installation process for the fire-resistant panel 1 according to this embodiment, as shown in Figure 9, will now be described. For the installation of the elements to be installed 3, please refer to the previously described instructions. For the installation of the lower end of the fire-resistant panel 1, please refer to Figure 2 and the previously described instructions based on Figure 2 as appropriate.

[0052] Prepare a first intermediate mounting element 4, and attach the first horizontal side 40 of the first intermediate mounting element 4 to the first side portion of the lower surface portion 30 of the element to be mounted 3 with a screw S1. At this time, the first horizontal side 40 and the lower surface portion 30 of the element to be mounted 3 are spaced apart, and the insulating material 5 is sandwiched between the first horizontal side 40 and the lower surface portion 30 for fixing. Prepare a second intermediate mounting element 5, and attach the second horizontal side 50 of the second intermediate mounting element 5 to the second side portion of the lower surface portion 30 of the element to be mounted 3 with a screw S2. At this time, the first horizontal side 50 and the lower surface portion 30 of the element to be mounted 3 are spaced apart, and the insulating material 15 is sandwiched between the second horizontal side 50 and the lower surface portion 30 for fixing.

[0053] Prepare the first lower fixing element 8 and fix the first lower edge 80 to a predetermined position on the floor surface FL with screws S4 (see Figure 2). The first vertical edge 61 of the first fixing element 6 and the first vertical edge 81 of the first lower fixing element 8 are located on the same vertical plane. At this stage, the insulation material 17 may be placed on the floor surface FL. Alternatively, the insulation material 17 may be pre-bonded to the lower end surface 14 of the fire-resistant panel 1. The installation order of the first intermediate mounting element 4, the second intermediate mounting element 5, and the first lower fixing element 8 is arbitrary.

[0054] With the first upper side 60 of the first fixing element 6 in contact with the lower surface 220 of the steel beam 2, the first vertical side 61 is fixed to the first vertical side 41 of the first intermediate mounting element 4 with a screw S3. At this stage, the insulation material 15 and insulation material 16 may be partially filled. The installation order of the first fixing element 6 is arbitrary as long as it is after the installation of the first intermediate mounting element 4, and may be after the installation of the fire-resistant panel 1.

[0055] Prepare the fire-resistant panel 1, and fix the upper part of the first surface portion 10 to the first vertical side 41 of the first intermediate mounting element 4 with a screw S5, and fix the lower part of the first surface portion 11 to the first vertical side 81 of the first lower fixing element 8 with a screw S6. At this stage, fill the space or gap between the upper end surface 13 and the lower surface 220 of the fire-resistant panel 1 with insulation material 15 and insulation material 16. If the insulation material 15 and insulation material 16 have already been partially filled, the remaining space or gap may be filled with insulation material 15 and insulation material 16.

[0056] In this embodiment, the second vertical side 51' of the second intermediate mounting element 5 rises upward and away from the upper end surface 13 of the fire-resistant panel 1. As a result, when the upper end portion of the fire-resistant panel 1 is mounted, a larger space is formed below the second intermediate mounting element 5 (compared to the second vertical side 51, which is a hanging side). The upper end surface 13 of the fire-resistant panel 1 does not interfere with the second vertical side 51', allowing the upper end portion of the fire-resistant panel 1 to be smoothly fitted into the space, thereby improving workability.

[0057] The second surface 11 of the fire-resistant panel 1 and the second vertical side 51' of the second intermediate mounting element 5 are located on the same vertical plane. With the second upper side 70 of the second fixing element 7 in contact with the lower surface 220 of the steel beam 2, the second vertical side 71 is brought into contact with the second vertical side 51' of the second intermediate mounting element 5 and the upper part of the second surface 11 of the fire-resistant panel 1, respectively, and fixed with screws S7 and S8. A second lower fixing element 9 is prepared, and the second lower side 90 is fixed to a predetermined position on the floor surface FL with screws S9, and the second vertical side 91 is fixed to the lower part of the second surface 11 of the fire-resistant panel 1 with screws S10.

[0058] Although the embodiment shown in Figure 9 has been described as a modification of the embodiment shown in Figure 6, in the embodiment shown in Figure 3, a second intermediate mounting element 5 having a second vertical side 51' may be used instead of a second intermediate mounting element 5 having a second vertical side 51 which is a hanging side.
