[Modes for carrying out the invention]

[0016] An embodiment of the present invention is described below. However, the present invention is not limited to this embodiment.

[0017] Figure 1A schematically shows in cross-sectional view an example of a heat-resistant block 1 according to this embodiment and an example of a corner section 100 on which the heat-resistant block 1 is installed. Figure 1B schematically shows in cross-sectional view an example of a heat-resistant structure 2 according to this embodiment, including the heat-resistant block 1 and the corner section 100.

[0018] In this embodiment, the direction in which arrow Z extends in the figure is referred to as the "up-down direction Z," the direction pointed to by arrowhead Z1 is referred to as "upward Z1," and the direction pointed to by arrowhead Z2 is referred to as "downward Z2." Also, the direction in which arrow X extends in the figure is referred to as the "forward-backward direction X," the direction pointed to by arrowhead X1 is referred to as "forward X1," and the direction pointed to by arrowhead X2, which is the opposite direction, is referred to as "backward X2." In the examples shown in Figures 1A and 1B, the up-down direction Z is approximately vertical, and the forward-backward direction X is approximately horizontal.

[0019] The corner section 100, which is the target of the heat-resistant block 1, is formed by projecting out from the wall surface 200. That is, in the example shown in Figures 1A and 1B, the corner section 100 is formed by projecting downward Z2 from the wall surface 200, which is a ceiling surface extending in a substantially horizontal direction.

[0020] However, the corner portion 100 is not particularly limited as long as the effects of the present invention are obtained. That is, Figure 1C schematically shows another example of the heat-resistant structure 2 according to this embodiment in cross-sectional view. In the example shown in Figure 1C, the front-to-back direction X is substantially vertical, and the up-and-down direction Z is substantially horizontal. The corner portion 100 may be formed by projecting substantially horizontally from the wall surface 200 that extends substantially vertically, as shown in Figure 1C. Furthermore, Figure 1D schematically shows yet another example of the heat-resistant structure 2 according to this embodiment in cross-sectional view. In the example shown in Figure 1D, the direction in which arrow V extends is substantially vertical, and the direction in which arrow H extends is substantially horizontal. The corner portion 100 may be formed by projecting downwards from the wall surface 200 that extends substantially horizontally, as shown in Figure 1D. In this embodiment, the explanation will mainly follow the examples shown in Figures 1A and 1B.

[0021] The corner portion 100 has an L-shape in cross-sectional view. That is, the corner portion 100 has a vertical wall portion 110 extending in the vertical direction Z, and a lower wall portion 120 extending forward X1 from the lower end Z2 of the vertical wall portion.

[0022] The corner portion 100 has a vertical surface 111 extending in the vertical direction Z, and a lower surface 121 that extends forward X1, connected to the lower end Z2 of the vertical surface 111. The vertical surface 111 of the corner portion 100 is the surface of a vertical wall portion 110 that is covered by a part of the heat-resistant block 1, and the lower surface 121 is the surface of a lower wall portion 120 that is covered by another part of the heat-resistant block 1.

[0023] The corner section 100 may be formed by projecting from the interior wall surface 200 into the interior space 210, as shown in Figures 1A to 1D. In this case, the corner section 100 constitutes a partition wall separating the interior space 210 from the exterior space 220. The heat-resistant block 1 is then installed in the interior space 210 so as to cover the corner section 100.

[0024] The wall surface 200 is not particularly limited as long as the effects of the present invention are obtained, but may be, for example, an industrial furnace (e.g., a heating furnace (e.g., a hot rolling furnace), a heat treatment furnace, an incinerator, a melting furnace, a soaking furnace, a forging furnace or a decomposition furnace), a furnace lid, an insulating cover, or the inner wall surface of a transport trolley. In other words, the heat-resistant block 1 is, for example, a heat-resistant lining material that protects the inner wall of an industrial furnace.

[0025] The heat-resistant block 1 is a heat-resistant member installed to cover the corner portion 100. The heat-resistant block 1 has an L-shape that corresponds to the surface shape formed by the vertical surface 111 and the lower surface 121 of the corner portion 100. That is, the heat-resistant block 1 has an L-shaped vertical portion 10 extending in the vertical direction Z, and an L-shaped bottom portion 20 extending forward X1 from the lower end Z2 of the L-shaped vertical portion 10.

[0026] The L-shaped vertical portion 10 of the heat-resistant block 1 is installed so as to cover the vertical surface 111 of the corner portion 100, and the L-shaped bottom portion 20 of the heat-resistant block 1 is installed so as to cover the lower surface 121 of the corner portion 100.

[0027] The L-shaped vertical portion 10 of the heat-resistant block 1 has a front surface 11 extending in the vertical direction Z, and the L-shaped bottom portion 20 of the heat-resistant block 1 has an upper surface 21 extending forward X1 from the lower end Z2 of the front surface 11.

[0028] In the installation of the heat-resistant block 1 to the corner portion 100, the front surface 11 of the L-shaped vertical portion 10 of the heat-resistant block 1 is positioned opposite the vertical surface 111 of the corner portion 100, and the upper surface 21 of the L-shaped bottom portion 20 of the heat-resistant block 1 is positioned opposite the lower surface 121 of the corner portion 100.

[0029] In this embodiment, the upper surface 21 of the L-shaped bottom portion 20 extends approximately perpendicular to the front surface 11 of the L-shaped vertical portion 10. The angle θ (see Figure 1A) between the front surface 11 of the L-shaped vertical portion 10 and the upper surface 21 of the L-shaped bottom portion 20 should be adjusted to correspond to the angle between the vertical surface 111 and the lower surface 121 of the corner portion 100. For example, it may be 60° or more and 120° or less, 70° or more and 110° or less, 80° or more and 100° or less, or 85° or more and 95° or less.

[0030] The heat-resistant structure 2 according to this embodiment has a corner portion 100 and a heat-resistant block 1 that covers the corner portion 100. In this heat-resistant structure 2, the heat-resistant block 1 covers the vertical surface 111 of the corner portion 100 with its L-shaped vertical portion 10 (particularly the front surface 11) and covers the lower surface 121 of the corner portion 100 with its L-shaped bottom portion 20 (particularly the top surface 21).

[0031] In the heat-resistant structure 2, the upper end face 12 of the L-shaped vertical portion 10 of the heat-resistant block 1 at Z1 may not cover the wall surface 200 on which the corner portion 100 protrudes, as shown in Figures 1B to 1D, but is not limited to this, and may cover the wall surface 200 (i.e., for example, the end face 12 may abut against the wall surface 200).

[0032] Furthermore, if the corner portion 100 is formed by protruding in the front-rear direction from a wall surface that extends in the vertical direction Z, the front end face 22 X1 of the L-shaped bottom portion 20 of the heat-resistant block 1 may not cover the wall surface, or it may cover the wall surface (i.e., for example, the end face 22 may abut against the wall surface).

[0033] Figure 2A shows an example of a specific configuration of the heat-resistant block 1 in a perspective view from the front and above. Figure 2B shows the heat-resistant block 1 shown in Figure 2A in a perspective view from the front and below. Figure 3 shows an example of a specific configuration of the corner portion 100, with a part of it virtually cut out and shown in a perspective view from the rear and below. In this embodiment, the direction in which the arrow Y in the figure extends (the direction perpendicular to the vertical direction Z and the front-to-back direction X) is referred to as the "width direction Y".

[0034] The heat-resistant block 1 has an L-shaped side surface 1a when viewed from the width direction Y, i.e., in a side view. The material constituting the heat-resistant block 1 is not particularly limited as long as the effects of the present invention are obtained, but the heat-resistant block 1 is preferably an inorganic fiber, for example.

[0035] The inorganic fibers constituting the inorganic fiber body are not particularly limited as long as the effects of the present invention are obtained, but it is preferable that they be one or more selected from the group consisting of alumina fibers, silica fibers, silica-alumina fibers, glass fibers, zirconia fibers, alkaline earth metal salt silicate fibers (biosoluble inorganic fibers), rock wool, and basalt fibers, and it is particularly preferable that they be one or more selected from the group consisting of alumina fibers, silica fibers, silica-alumina fibers, and alkaline earth metal salt silicate fibers.

[0036] The ratio of the weight of inorganic fibers contained in the inorganic fiber material to the total weight of the inorganic fiber material is not particularly limited as long as the effects of the present invention are obtained, but for example, it is preferably 30% by weight or more, more preferably 35% by weight or more, even more preferably 40% by weight or more, even more preferably 45% by weight or more, even more preferably 50% by weight or more, even more preferably 60% by weight or more, even more preferably 70% by weight or more, even more preferably 75% by weight or more, preferably 80% by weight or more, and particularly preferably 85% by weight or more. In addition, the ratio of the weight of inorganic fibers contained in the inorganic fiber material to the total weight of the inorganic fiber material may be, for example, 95% by weight or less.

[0037] The inorganic fiber material is preferably, for example, a laminate of inorganic fiber blankets. That is, in this case, the heat-resistant block 1 may be constructed by laminating multiple L-shaped inorganic fiber blankets, or each of the L-shaped vertical portion 10 and L-shaped bottom portion 20 of the heat-resistant block 1 may be formed by laminating multiple inorganic fiber blankets.

[0038] The lamination of inorganic fiber blankets may be a lamination of multiple inorganic fiber blankets that are separable from each other (for example, a lamination of multiple L-shaped inorganic fiber blankets that are separable from each other), or it may be a lamination by folding a single inorganic fiber blanket multiple times (for example, a lamination by repeatedly folding a long inorganic fiber blanket into mountain folds and valley folds).

[0039] The weight of the heat-resistant block 1 is not particularly limited as long as the effects of the present invention are obtained, but for example it may be 0.5 kg or more, 1 kg or more, 3 kg or more, 5 kg or more, 10 kg or more, 15 kg or more, or 20 kg or more. Alternatively, the weight of the heat-resistant block 1 may be, for example, 30 kg or less.

[0040] The front surface 11 of the L-shaped vertical section 10 of the heat-resistant block 1 is provided with a front mounting section 30 which is fixed to a vertical mounting section 130 provided on the vertical surface 111 of the corner section 100. In other words, a vertical mounting section 130 is provided in advance on the vertical surface 111 of the corner section 100, and the front surface 11 of the L-shaped vertical section 10 of the heat-resistant block 1, which is installed to cover the vertical surface 111, is provided with a front mounting section 30 which can be fixed to the vertical mounting section 130.

[0041] The upper surface 21 of the L-shaped bottom portion 20 of the heat-resistant block 1 is provided with an upper mounting portion 40 that engages with a lower mounting portion 140 provided on the lower surface 121 of the corner portion 100. In other words, the lower surface 121 of the corner portion 100 is pre-provided with a lower mounting portion 140, and the upper surface 21 of the L-shaped bottom portion 20 of the heat-resistant block 1, which is constructed to cover the lower surface 121, is provided with an upper mounting portion 40 that can engage with the lower mounting portion 140.

[0042] Figure 4A shows an example of a specific configuration of the lower mounting portion 140 of the corner portion 100 in a perspective view from the front. Figure 4B shows an example of a specific configuration of the upper mounting portion 40 of the heat-resistant block 1 in a perspective view from the front and above. Figure 4C shows an example of the state in which the lower mounting portion 140 shown in Figure 4A and the upper mounting portion 40 shown in Figure 4B are engaged, in a perspective view from the front and above. Figure 4D shows the engaged state of the lower mounting portion 140 and the upper mounting portion 40 shown in Figure 4C in a front view.

[0043] Figure 5A shows a front perspective view of the heat-resistant block 1 shown in Figures 2A and 2B before it is installed on the corner section 100 shown in Figure 3. Figure 5B shows a front and bottom perspective view of the corner section 100 and heat-resistant block 1 shown in Figure 5A. Figure 5C shows a side view of the corner section 100 and heat-resistant block 1 shown in Figure 5A from the width direction. Figure 5D shows a rear and bottom perspective view of the heat-resistant block 1 with the front X1 end of the upper mounting section 40 of the heat-resistant block 1 shown in Figures 2A and 2B engaged with the lower mounting section 140 of the corner section 100 shown in Figure 3, with the parts of the heat-resistant block 1 other than the upper mounting section 40 omitted. Figure 5E shows a rear and bottom perspective view of the heat-resistant structure 2 obtained by installing the heat-resistant block 1 shown in Figures 2A and 2B on the corner section 100 shown in Figure 3.

[0044] Figure 6A shows another example of a specific configuration of the lower mounting portion 140 of the corner portion 100 in a cross-sectional view from the front. Figure 6B shows another example of a specific configuration of the upper mounting portion 40 of the heat-resistant block 1 in a cross-sectional view from the front. Figure 6C shows the engagement state between the lower mounting portion 140 shown in Figure 6A and the upper mounting portion 40 shown in Figure 6B in a cross-sectional view from the front.

[0045] The upper mounting portion 40 of the heat-resistant block 1 engages with the lower mounting portion 140 of the corner portion 100, thereby positioning the front mounting portion 30 of the heat-resistant block 1 opposite the vertical mounting portion 130 of the corner portion 100. It is also configured to move the front mounting portion 30 linearly to a position where it can be fixed to the vertical mounting portion 130 by sliding linearly while engaged with the lower mounting portion 140.

[0046] Specifically, in the installation of the heat-resistant block 1 on the corner portion 100 (i.e., the manufacture of the heat-resistant structure 2), first, the front X1 end of the upper mounting portion 40 of the heat-resistant block 1 is engaged with the lower mounting portion 140 of the corner portion 100 (see Figure 5D).

[0047] Here, it is preferable that the upper mounting portion 40 of the heat-resistant block 1 extends to the front end of the L-shaped bottom portion 20 of the heat-resistant block 1. Specifically, as shown in Figures 2B and 5B, for example, it is preferable that the upper mounting portion 40 extends to the front end of the L-shaped bottom portion 20 such that the front end of the upper mounting portion 40 is visible from a position where the front end X1 22 and the lower end Z2 23 of the L-shaped bottom portion 20 of the heat-resistant block 1 are visible.

[0048] Because the upper mounting portion 40 of the heat-resistant block 1 extends to the front end of the L-shaped bottom portion 20, for example, a worker performing construction work with the heat-resistant block lifted from below can easily confirm the position of the upper mounting portion 40 from below the heat-resistant block 1. This allows for efficient alignment and engagement of the upper mounting portion 40 with the lower mounting portion 140 of the corner portion 100.

[0049] The upper mounting portion 40 may have its front end extending further forward X1 than the front end of the L-shaped base portion 20, but it is preferable that it is provided within the range of the upper surface 21 of the L-shaped base portion 20, as shown in Figures 2A, 2B, 5B, and 5C.

[0050] Furthermore, the upper mounting portion 40 of the heat-resistant block 1 engages with the lower mounting portion 140 of the corner portion 100 to prevent the heat-resistant block 1 from moving downward Z2 and moving in the width direction Y. That is, the engagement between the upper mounting portion 40 of the heat-resistant block 1 and the lower mounting portion 140 of the corner portion 100 includes an engagement that prevents the heat-resistant block 1 from moving downward Z2 and an engagement that prevents the heat-resistant block 1 from moving in the width direction Y.

[0051] Therefore, the engagement between the upper mounting portion 40 of the heat-resistant block 1 and the lower mounting portion 140 of the corner portion 100 makes it possible to determine the relative positional relationship between the front mounting portion 30 of the heat-resistant block 1 and the vertical mounting portion 130 of the corner portion 100 in the vertical direction Z and the width direction Y.

[0052] Specifically, the front mounting portion 30 of the heat-resistant block 1 is first provided on the front surface 11 of the L-shaped vertical portion 10 of the heat-resistant block 1 so that when the upper mounting portion 40 of the heat-resistant block 1 is engaged with the lower mounting portion 140 of the corner portion 100, it is positioned opposite the vertical mounting portion 130 of the corner portion 100.

[0053] On the other hand, the upper mounting portion 40 of the heat-resistant block 1 is configured to engage with the lower mounting portion 140 of the corner portion 100, thereby preventing the heat-resistant block 1 from moving downward Z2 and moving in the width direction Y.

[0054] The structure of the upper mounting portion 40 for achieving engagement that prevents the heat-resistant block 1 from moving downward Z2 and in the width direction Y is not particularly limited as long as the effects of the present invention are obtained, but in the example shown in Figures 4A to 4D, the upper mounting portion 40 has a first surface 40a that abuts a part of the lower mounting portion 140 of the corner portion 100 from above (towards downward Z2), and a second surface 40b that is sandwiched by another part of the lower mounting portion 140 in the width direction Y.

[0055] In this example, the lower mounting portion 140 of the corner portion 100 has a first surface 140a that supports the first surface 40a of the upper mounting portion 40 of the heat-resistant block 1 from below (towards upward Z1), and a second surface 140b that clamps the second surface 40b of the upper mounting portion 40 in the width direction Y.

[0056] Then, the upper mounting portion 40 and the lower mounting portion 140 engage so that the first surface 40a of the upper mounting portion 40 of the heat-resistant block 1 abuts against the first surface 140a of the lower mounting portion 140 of the corner portion 100 from above, thereby suspending the heat-resistant block 1 from the corner portion 100 via the upper mounting portion 140. As a result, downward movement of the heat-resistant block 1 in the Z direction is prevented.

[0057] Furthermore, the movement of the heat-resistant block 1 in the width direction Y is prevented by the engagement of the upper mounting portion 40 and the lower mounting portion 140 such that the pair of second surfaces 40b of the upper mounting portion 40 of the heat-resistant block 1 are sandwiched in the width direction Y by the pair of second surfaces 140b of the lower mounting portion 140 of the corner portion 100.

[0058] Furthermore, in the example shown in Figures 6A to 6C, the upper mounting portion 40 of the heat-resistant block 1 has a first surface 40a that abuts a part of the lower mounting portion 140 of the corner portion 100 from above (towards downward Z2), and a second surface 40b that clamps another part of the lower mounting portion 140 in the width direction Y.

[0059] In this example, the lower mounting portion 140 of the corner portion 100 has a first surface 140a that supports the first surface 40a of the upper mounting portion 40 of the heat-resistant block 1 from below (towards upward Z1), and a second surface 140b that is sandwiched between the second surface 40b of the upper mounting portion 40 in the width direction Y.

[0060] Then, the upper mounting portion 40 and the lower mounting portion 140 engage so that the first surface 40a of the upper mounting portion 40 of the heat-resistant block 1 abuts against the first surface 140a of the lower mounting portion 140 of the corner portion 100 from above. As a result, the heat-resistant block 1 is suspended from the corner portion 100 via the upper mounting portion 140, and its movement downward Z2 is prevented.

[0061] Furthermore, the movement of the heat-resistant block 1 in the width direction Y is prevented by the engagement of the upper mounting portion 40 and the lower mounting portion 140 such that the pair of second surfaces 40b of the upper mounting portion 40 of the heat-resistant block 1 clamps the pair of second surfaces 140b of the lower mounting portion 140 of the corner portion 100 in the width direction Y.

[0062] In this way, the upper mounting portion 40 of the heat-resistant block 1 engages with the lower mounting portion 140 of the corner portion 100, thereby positioning the front mounting portion 30 of the heat-resistant block 1 opposite the vertical mounting portion 130 of the corner portion 100, and preventing the front mounting portion 30 from moving downward in the Z direction and widthwise in the Y direction, thereby maintaining the relative position of the front mounting portion 30 with respect to the vertical mounting portion 130 in the vertical Z direction and widthwise in the Y direction.

[0063] The specific shapes of the upper mounting portion 40 and the lower mounting portion 140 for achieving the engagement described above are not particularly limited as long as the effects of the present invention are obtained. However, in the example shown in Figures 4A to 4D, the upper mounting portion 40 has a base portion 41, a pair of support portions 42 erected above Z1 from the base portion 41 and spaced apart in the width direction Y, and a pair of flange portions 43 extending from the pair of support portions 42 in the width direction Y (specifically, outward in the width direction Y, moving away from each other).

[0064] Furthermore, the lower mounting portion 140 of the corner portion 100 has a base portion 141, a pair of support portions 142 erected downward Z2 from the base portion 141 and spaced apart in the width direction Y, and a pair of flange portions 143 extending from the pair of support portions 142 in the width direction Y (specifically, in the inward direction, approaching each other in the width direction Y).

[0065] In this example, the upper mounting portion 40 is configured to contact the first surface 140a of the lower mounting portion 140 from above, with the first surface 40a of the flange portion 43 (specifically, the lower surface of the flange portion 43) having the surface 40a of the flange portion 43.

[0066] Furthermore, the upper mounting portion 40 is configured such that, in the width direction Y, the surface of its flange portion 43 (specifically, the end face of the flange portion 43 in the width direction Y) is sandwiched by the second surface 140b of the lower mounting portion 140 (specifically, the inner surface of the support portion 142 in the width direction Y).

[0067] Furthermore, in the example shown in Figures 6A to 6C, the upper mounting portion 40 of the heat-resistant block 1 has a base portion 41, a pair of support portions 42 erected above Z1 from the base portion 41 and spaced apart in the width direction Y, and a pair of flange portions 43 extending from the pair of support portions 42 in the width direction Y (specifically, in the inward direction, approaching each other in the width direction Y).

[0068] Furthermore, in the example shown in Figures 6A to 6C, the lower mounting portion 140 of the corner portion 100 has a base portion 141, a pair of support portions 142 erected downward Z2 from the base portion 141 and spaced apart in the width direction Y, and a pair of flange portions 143 extending from the pair of support portions 142 in the width direction Y (specifically, outward in the width direction Y, moving away from each other).

[0069] In this example, the upper mounting portion 40 is configured to contact the first surface 140a of the lower mounting portion 140 from above, with the first surface 40a of the flange portion 43 (specifically, the lower surface of the flange portion 43) having the surface 40a of the flange portion 43.

[0070] Furthermore, the upper mounting portion 40 is configured to clamp the second surface 140b of the lower mounting portion 140 (specifically, the outer surface of the support portion 142 in the width direction Y) with the second surface 40b, which is the surface of the flange portion 43 (specifically, the end face of the flange portion 43 in the width direction Y).

[0071] Furthermore, the upper mounting portion 40 is configured such that, in the width direction Y, the second surface 40b, which is the surface of the support portion 42 (specifically, the inner surface of the support portion 42 in the width direction Y), clamps the second surface 140b, which is the surface of the flange portion 143 of the lower mounting portion 140 (specifically, the end face of the flange portion 143 in the width direction Y).

[0072] The combination of the first surface 40a and second surface 40b of the upper mounting portion 40 of the heat-resistant block 1 and the first surface 40a and second surface 40b of the lower mounting portion 140 of the corner portion 100 is not limited to the example described above.

[0073] In other words, the first surface 40a of the upper mounting portion 40 of the heat-resistant block 1 may be one or more surfaces selected from the group consisting of the base portion 41 and the flange portion 43, and the second surface 40b of the upper mounting portion 40 may be one or more surfaces selected from the group consisting of the base portion 41, the support portion 42 and the flange portion 43.

[0074] Furthermore, the first surface 140a of the lower mounting portion 140 of the corner portion 100 may be one or more surfaces selected from the group consisting of the base portion 141 and the flange portion 143, and the second surface 140b of the lower mounting portion 140 may be one or more surfaces selected from the group consisting of the base portion 141, the support portion 142 and the flange portion 143.

[0075] In the examples shown in Figures 4A to 4D and Figures 6A to 6C, the upper mounting portion 40 of the heat-resistant block 1 has legs 44 that extend downward Z2 from the base portion 41 and are embedded in and fixed to the L-shaped bottom portion 20 of the heat-resistant block 1.

[0076] The leg portion 44 may have a reinforcing member (not shown) that extends in the width direction Y and is embedded in and fixed to the L-shaped base portion 20. In the example shown in Figure 4B, a hole 44a is formed in the leg portion 44 through which this reinforcing member is inserted for fixing to the leg portion 44.

[0077] Furthermore, in the examples shown in Figures 4A to 4D and Figures 6A to 6C, the lower mounting portion 140 of the corner portion 100 has a shaft portion 144 that extends upward Z1 from the base portion 141 and is fixed to the corner portion 100.

[0078] In the installation of the heat-resistant block 1 on the corner portion 100 (i.e., the manufacture of the heat-resistant structure 2), the upper mounting portion 40 of the heat-resistant block 1 is then linearly slid while engaged with the lower mounting portion 140 of the corner portion 100, thereby linearly moving the front mounting portion 30 of the heat-resistant block 1 to a position where it can be fixed to the vertical mounting portion 130 of the corner portion 100.

[0079] In other words, as described above, first, as shown in Figure 5D, the front end of the upper mounting portion 40 of the heat-resistant block 1 is engaged with the rear end of the lower mounting portion 140 of the corner portion 100, thereby positioning the front mounting portion 30 of the heat-resistant block 1 opposite the vertical mounting portion 130 of the corner portion 100.

[0080] Next, while maintaining the engagement between the upper mounting portion 40 and the lower mounting portion 140, that is, while positioning the front mounting portion 30 of the heat-resistant block 1 opposite the vertical mounting portion 130 of the corner portion 100, the upper mounting portion 40 is slid linearly further forward X1.

[0081] In other words, in the examples shown in Figures 4A to 4D and Figures 6A to 6C, the upper mounting portion 40 and the lower mounting portion 140 are configured to extend linearly in the front-rear direction X so that the upper mounting portion 40 can slide linearly forward X1 while remaining engaged with the lower mounting portion 140.

[0082] Specifically, the upper mounting portion 40 of the heat-resistant block 1 has a first surface 40a and a second surface 40b that extend linearly in the front-rear direction X. More specifically, the base portion 41, support portion 42, and flange portion 43 of the upper mounting portion 40 are configured such that the surfaces that can become the first surface 40a and the second surface 40b extend linearly in the front-rear direction X.

[0083] Furthermore, the lower mounting portion 140 of the corner portion 100 also has a first surface 140a and a second surface 140b that extend linearly in the front-rear direction X. More specifically, the base portion 141, support portion 142, and flange portion 143 of the lower mounting portion 140 are configured such that the surfaces that can become the first surface 140a and the second surface 140b extend linearly in the front-rear direction X.

[0084] Therefore, when installing the heat-resistant block 1 on the corner portion 100, after engaging the front end of the upper mounting portion 40 of the heat-resistant block 1 with the rear end of the lower mounting portion 140 of the corner portion 100, the worker can move the heat-resistant block 1 forward X1 while maintaining the engaged state so that the upper mounting portion 40 slides linearly further forward X1, thereby bringing the front mounting portion 30 of the heat-resistant block 1 to a position where it can be fixed to the vertical mounting portion 130 of the corner portion 100.

[0085] In other words, because the heat-resistant block 1 has the upper mounting portion 40 described above, the front mounting portion 30 of the heat-resistant block 1 can be efficiently aligned and fixed with respect to the vertical mounting portion 130 of the corner portion 100.

[0086] The number of upper mounting portions 40 provided on the heat-resistant block 1 is not particularly limited as long as the effects of the present invention are obtained, but it is preferable that the heat-resistant block 1 has one upper mounting portion 40, as in this embodiment.

[0087] Furthermore, it is preferable that the corner portion 100 has a number of lower mounting portions 140 corresponding to the number of upper mounting portions 40 on one heat-resistant block 1, and arranged in the same number and configuration. In this embodiment, the corner portion 100 has one lower mounting portion 140 on one heat-resistant block 1.

[0088] Furthermore, in the heat-resistant structure 2 manufactured by applying the heat-resistant block 1 to the corner portion 100, the engagement between the upper mounting portion 40 of the heat-resistant block 1 and the lower mounting portion 140 of the corner portion 100 may occur outside the range of the upper surface 21 of the L-shaped bottom portion 20 of the heat-resistant block 1, but it is preferable that it be performed within the range of the upper surface 21, as in the example described above.

[0089] In other words, it is preferable that the upper mounting portion 40 of the heat-resistant block 1 be provided within the range of the upper surface 21 of the L-shaped bottom portion 20 of the heat-resistant block 1, and that the lower mounting portion 140 of the corner portion 100 be provided within the range of the lower surface 121 of the corner portion 100 that is covered by the upper surface 21 of the heat-resistant block 1.

[0090] Furthermore, in this heat-resistant structure 2, the engagement between the front mounting portion 30 of the heat-resistant block 1 and the vertical mounting portion 130 of the corner portion 100 may be performed outside the area of ​​the front surface 11 of the L-shaped vertical portion 10 of the heat-resistant block 1, but it is preferable that it be performed within the area of ​​the front surface 11, as in the example described above.

[0091] In other words, it is preferable that the front mounting portion 30 of the heat-resistant block 1 be provided within the range of the front surface 11 of the L-shaped vertical portion 10 of the heat-resistant block 1, and that the vertical mounting portion 130 of the corner portion 100 be provided within the range of the vertical surface 111 of the corner portion 100 that is covered by the front surface 11 of the heat-resistant block 1.

[0092] The front mounting portion 30 of the heat-resistant block 1 is not particularly limited as long as it is a member that can be fixed to the vertical mounting portion 130 of the corner portion 100. That is, for example, the front mounting portion 30 of the heat-resistant block 1 may be fixed to the vertical mounting portion 130 of the corner portion 100 by fastening using a screw structure such as bolts and nuts.

[0093] Specifically, for example, the front mounting portion 30 of the heat-resistant block 1 may include a member having a female screw structure (e.g., a tall nut), and the vertical mounting portion 130 of the corner portion 100 may have an insertion hole formed through which a member having a male screw structure (e.g., a bolt) is inserted.

[0094] In this case, as described above, the front mounting portion 30 of the heat-resistant block 1 is slid while engaged with the lower mounting portion 140 of the corner portion 100, so that it reaches a position where it can be fixed to the vertical mounting portion 130 of the corner portion 100. Then, the front mounting portion 30 and the vertical mounting portion 130 are fixed by inserting a member having a male screw structure into the female screw structure of the front mounting portion 30 through the insertion hole of the vertical mounting portion 130 and fastening it.

[0095] However, when using fastening members with such screw structures, the alignment of the front mounting portion 30 of the heat-resistant block 1 and the vertical mounting portion 130 of the corner portion 100 is performed in the indoor space 210 (see Figures 1A to 1D), while the final fixing work between the front mounting portion 30 and the vertical mounting portion 130 (for example, the work of inserting bolts to fix them) must be performed from the outdoor space 220.

[0096] In contrast, if not only can the alignment of the front mounting portion 30 of the heat-resistant block 1 and the vertical mounting portion 130 of the corner portion 100 be completed in the indoor space 210, but the fixing work can also be completed in the indoor space 210, the time and labor required for construction can be reduced even more effectively.

[0097] In this regard, Figure 7A shows an example of a specific configuration of the vertical mounting portion 130 of the corner portion 100 in oblique and side views. Specifically, Figure 7A(i) shows an example of the vertical mounting portion 130 in an oblique view from the rear, and Figure 7A(ii) shows an example of the vertical mounting portion 130 in a side view from the width direction. Figure 7B shows an example of a specific configuration of the front mounting portion 30 of the heat-resistant block 1 in oblique and side views. Specifically, Figure 7B(i) shows an example of the vertical mounting portion 130 in an oblique view from the rear, Figure 7B(ii) shows an example of the vertical mounting portion 130 in a side view from the width direction, and Figure 7B(iii) shows an example of the vertical mounting portion 130 in an oblique view from the front. Figure 7C shows a side view from the width direction showing the state in which the vertical mounting portion 130 shown in Figure 7A and the front mounting portion 30 shown in Figure 7B are engaged.

[0098] In the example shown in Figures 7A to 7C, a portion of the vertical mounting portion 130 can be inserted into the front mounting portion 30. gap 31 is formed. And this front mounting portion 30 is a part of the vertical mounting portion 130 gap While allowing 31 to pass in the insertion direction (rear X2 in the figure), a part of the vertical mounting portion 130 is gap After passing through 31, it engages with another part of the vertical mounting portion 130, preventing the vertical mounting portion 130 from moving in the opposite direction to the insertion direction (forward X1 in the figure).

[0099] By configuring the front mounting portion 30 of the heat-resistant block 1 in this way, the upper mounting portion 40 of the heat-resistant block 1 is engaged with the lower mounting portion 140 of the corner portion 100 and slid linearly, bringing the front mounting portion 30 closer to the vertical mounting portion 130, and the front mounting portion 30 gap A portion of the vertical mounting portion 130 can be inserted through 31, and the front mounting portion 30 can be engaged with another portion of the vertical mounting portion 130. In other words, not only can the alignment of the front mounting portion 30 of the heat-resistant block 1 and the vertical mounting portion 130 of the corner portion 100 be completed, but the fixing work can also be completed in the interior space 210.

[0100] The specific structure of the front mounting portion 30 that achieves such engagement is not particularly limited as long as the effects of the present invention are obtained, but in the example shown in Figures 7A to 7C, the front mounting portion 30 has an elastic member 32 that forms a gap 31 through which a part of the vertical mounting portion 130 can be inserted.

[0101] Then, the front mounting portion 30 expands the gap 31 as the elastic member 32 elastically deforms, so that a part of the vertical mounting portion 130 that is larger than the gap 31 before expansion is gap While allowing 31 to pass through in the insertion direction, a part of the vertical mounting portion 130 is gap After passing through 31, the elastic member 32, having elastically restored itself, engages with another part of the vertical mounting portion 130 that is smaller than the part of the vertical mounting portion 130, thereby preventing the vertical mounting portion 130 from moving in the direction opposite to the insertion direction.

[0102] The elastic member 32 of the front mounting portion 30 is not particularly limited as long as the effects of the present invention are obtained, but for example, as shown in Figures 7B and 7C, a leaf spring is preferably used. That is, in the example shown in Figures 7B and 7C, the front mounting portion 30 has a base portion 33 and an elastic member 32 made of a pair of leaf springs provided spaced apart from the base portion 33 and extending while inclined toward each other in the insertion direction (rear X2 in the figure). In the example shown in Figures 7B and 7C, the pair of elastic members 32 made of leaf springs are provided spaced apart in the vertical direction Z.

[0103] A gap 31 is formed between the two spaced free ends of the elastic member 32. In addition, a hole 33a is formed in the base 33 at a position opposite to the gap 31 in the direction opposite to the insertion direction of the gap 31 (forward X1 in the figure) for inserting a part of the vertical mounting portion 130.

[0104] The front mounting portion 30 of the heat-resistant block 1 has a leg portion 34 that extends from the base portion 33 in the insertion direction (rear X2 in the figure) and is embedded in and fixed to the L-shaped vertical portion 10 of the heat-resistant block 1. The leg portion 34 may have a reinforcing member (not shown) that extends in the width direction Y and is embedded in and fixed to the L-shaped vertical portion 10. In the example shown in Figure 7B, a hole 34a is formed in the leg portion 34 for inserting and fixing this reinforcing member to the leg portion 34.

[0105] On the other hand, the vertical mounting portion 130 has a first portion 131 that is larger than the gap 31 of the front mounting portion 30, and a second portion 132 that is smaller than the first portion 131. Specifically, in the example shown in Figures 7A and 7C, the vertical mounting portion 130 is configured as a columnar member having a first portion 131 and a second portion 132.

[0106] Furthermore, the first portion 131 of the vertical mounting portion 130 is a columnar portion having a diameter larger than the gap 31 of the front mounting portion 30, and the second portion 132 is a columnar portion having a diameter smaller than the first portion 131. Specifically, the vertical mounting portion 140 is formed by repeatedly forming the first portion 131 and the second portion 132 in the longitudinal direction.

[0107] In other words, the vertical mounting portion 140 has a screw structure, and the combination of a first portion 131, which is the peak, and a second portion 132, which is the valley, is repeated in the longitudinal direction. More specifically, the first portion 131 has a tapered shape in which the diameter increases in the direction opposite to the insertion direction (forward X1 in the figure), and at least a part of the diameter of this tapered shape is larger than the gap 31 of the front mounting portion 30 of the heat-resistant block 1. In the example shown in Figure 7A, the vertical mounting portion 140 has a shaft portion 134 for fixing the screw portion 133, which includes multiple first portions 131 and second portions 132, to the corner portion 100.

[0108] Then, when fixing the front mounting portion 30 of the heat-resistant block 1 to the vertical mounting portion 130 of the corner portion 100, first the first portion 131 of the vertical mounting portion 130 is pushed into the gap 31 of the front mounting portion 30.

[0109] In other words, although the first portion 131 of the vertical mounting portion 130 is larger than the gap 31 of the front mounting portion 30, the elastic member 32 forming the gap 31 is elastic, and therefore the elastic member 32 is elastically deformed by being pressed in the insertion direction by the first portion 131, gap Enlarge 31.

[0110] Therefore, the first portion 131 of the vertical mounting portion 130 is enlarged gap It is possible to pass through 31. While the first portion 131 of the vertical mounting portion 130 passes through the gap 31, the elastic member 32 holds the first portion 32 by its elastic repulsive force.

[0111] Next, after the first portion 131 of the vertical mounting portion 130 passes through the gap 31, the second portion 132, which is formed in the opposite direction to the insertion direction of the first portion 131 (forward X1 in the figure), passes through the gap 31. However, since the second portion 132 is smaller than the first portion 131, the elastic member 32 of the front mounting portion 30 elastically returns to its original position and engages with the second portion 132, as shown in Figure 7C.

[0112] Furthermore, the engagement between the elastic member 32 of the front mounting portion 30 and the second portion 132 of the vertical mounting portion 130 prevents the first portion 131, which is larger than the second portion 132 that has already passed through the gap 31 of the front mounting portion 30, from moving in the opposite direction to the insertion direction (forward X1 in the figure).

[0113] In other words, the engagement between the elastic member 32 of the front mounting portion 30 and the second portion 132 of the vertical mounting portion 130 prevents the vertical mounting portion 130 from moving in the direction opposite to the insertion direction (forward X1 in the figure).

[0114] Furthermore, in the examples shown in Figures 7A to 7C, the vertical mounting portion 130 passes through the hole 33a of the base portion 33 of the front mounting portion 30 before passing through the gap 31 of the front mounting portion 30. For this reason, in the example shown in Figure 7C, the vertical mounting portion 130 engaged with the front mounting portion 30 engages with the elastic member 32 and is also supported by the base portion 33 of the front mounting portion 30.

[0115] By supporting the vertical mounting portion 130 with the elastic member 32 and base portion 33 of the front mounting portion 30, which are spaced apart in the insertion direction (front-to-back direction X in the figure), the engagement between the front mounting portion 30 and the vertical mounting portion 130 can be effectively stabilized, and the installation state of the heat-resistant block 1 on the corner portion 100 can be effectively maintained.

[0116] Furthermore, the front mounting portion 30 is a part of the vertical mounting portion 130 gap The embodiments that allow 31 to pass in the insertion direction are not limited to the examples described above. That is, for example, a part of the vertical mounting portion 130 may be made of an elastic member, and the part of the vertical mounting portion 130 may elastically deform to reduce its diameter by being pressed by a member constituting the gap 31 of the front mounting portion 30, thereby allowing the part to pass through the gap 31, and after passing through, the diameter of the part may be restored by elastic restoration, causing the other part of the vertical mounting portion 130 to engage with the member constituting the gap 31 of the front mounting portion 30 (see, for example, Japanese Patent No. 3592583).

[0117] Furthermore, it is preferable that the heat-resistant block 1 has a plurality of front mounting portions 30. In this embodiment, the heat-resistant block 1 has two front mounting portions 30. The arrangement of the plurality of front mounting portions 30 is not particularly limited as long as the effects of the present invention are obtained, but it is preferable that the heat-resistant block 1 has a plurality of front mounting portions 30 spaced apart in the vertical direction Z. In this embodiment, the heat-resistant block 1 has two front mounting portions 30 spaced apart in the vertical direction Z.

[0118] Furthermore, if the heat-resistant block 1 has multiple front mounting portions 30, it is preferable that the corner portion 100 has vertical mounting portions 130 in the same number and arrangement as the multiple front mounting portions 30 for each heat-resistant block 1.

[0119] As the front mounting portion 30 of the heat-resistant block 1 is configured as described above, work in the outdoor space 220 is eliminated or reduced, thereby effectively reducing the time and effort required for installation of the fire-resistant block 1 at the corner portion 100.

[0120] The heat-resistant structure 2 according to this embodiment (see Figures 1B to 1D and 5E) is manufactured by installing the heat-resistant block 1 on the corner portion 100, as described above. That is, the manufacturing method of the heat-resistant structure 2 includes an installation step which involves engaging the upper mounting portion 40 of the heat-resistant block 1 with the lower mounting portion 140 of the corner portion 100 to position the front mounting portion 30 of the heat-resistant block 1 opposite the vertical mounting portion 130 of the corner portion 100; linearly sliding the upper mounting portion 40 while it is engaged with the lower mounting portion 140 to move the front mounting portion 30 to a position where it can be fixed to the vertical mounting portion 130; and fixing the front mounting portion 30 and the vertical mounting portion 130.

[0121] The heat-resistant structure 2 may include a corner portion 100 and a plurality of heat-resistant blocks 1 covering the corner portion 100. In this case, the heat-resistant structure 2 includes a plurality of heat-resistant blocks 1 arranged adjacent to each other in the width direction Y.

[0122] Furthermore, the multiple heat-resistant blocks 1 are arranged in contact with each other in the width direction Y. That is, if the heat-resistant blocks 1 are inorganic fibrous materials, each of the multiple heat-resistant blocks 1 is arranged in contact with each other in a compressed state in the width direction Y. In this case, the multiple heat-resistant blocks 1 are stably held together by the repulsive force that causes the inorganic fibrous materials to expand in the width direction Y.

[0123] If the heat-resistant structure 2 includes a plurality of heat-resistant blocks 1, the manufacturing method of the heat-resistant structure 2 includes a plurality of construction steps performed for each of the plurality of heat-resistant blocks 1. In this case, the plurality of construction steps may be performed sequentially, or some or all of them may be performed in parallel.

[0124] Furthermore, when constructing multiple heat-resistant blocks 1, it is preferable that each heat-resistant block 1 has a sliding plate (not shown) covering its L-shaped side surface 1a. In other words, especially when the heat-resistant block 1 is made of inorganic fiber, the presence of a sliding plate on the heat-resistant block 1 effectively reduces friction between multiple heat-resistant blocks 1 installed adjacent to each other, thereby improving their constructability.

[0125] The sliding plate is not particularly limited as long as it can reduce friction between adjacent heat-resistant blocks 1. For example, cardboard or plywood is preferably used, but it is especially preferable to use a sliding plate with a resin coating on its surface (for example, poly plywood). The sliding plate may be removed after the adjacent heat-resistant blocks 1 have been installed.

[0126] Furthermore, if the corner portion 100 has a metal wall 300 and a heat-resistant layer 400 covering the surface of the metal wall 300 on the heat-resistant block 1 side, as shown in Figure 3, the manufacturing method of the heat-resistant structure 2 may include the following preparation steps prior to the above-described construction steps.

[0127] In other words, this preparation step includes fixing a part of the vertical mounting portion 130 and / or a part of the lower mounting portion 140 to the metal wall 300 to which the heat-resistant layer 400 has not yet been laminated; laminating the heat-resistant layer 400 onto the surface of the metal wall 300 to which the part of the vertical mounting portion 130 and / or a part of the lower mounting portion 140 is fixed; and, after the lamination of the heat-resistant layer 400, connecting the remaining part of the vertical mounting portion 130 and / or the remaining part of the lower mounting portion 140 to the part of the vertical mounting portion 130 and / or the part of the lower mounting portion 140 fixed to the metal wall 300.

[0128] Specifically, Figure 8A shows a cross-sectional view of the metal wall 300 before the heat-resistant layer 400 is laminated. A vertical metal surface 310 extending in the vertical direction Z of the metal wall 300 has a vertical surface hole 310a for fixing the vertical surface mounting portion 130. In addition, a lower metal surface 320 extending forward X1 from the lower end Z2 of the metal vertical surface 310 of the metal wall 300 has a lower surface hole 320a for fixing the lower surface mounting portion 130.

[0129] Therefore, as shown in Figure 8B, first, a part of the vertical mounting portion 130 (specifically, the shaft portion 134 (see Figure 7A)) is inserted through the vertical hole 310a of the metal wall 300 and fixed to the metal wall 300 (for example, the shaft portion 134, which is made of a tall nut, is inserted through the vertical hole 310a from the indoor space 210 side, and the tall nut is fixed from the outdoor space 220 side with a washer and a nut), and a part of the lower mounting portion 140 (specifically, the shaft portion 144 (see Figure 4A)) is inserted through the lower hole 320a of the metal wall 300 and fixed to the metal wall 300 (for example, the shaft portion 144, which is made of a tall nut, is inserted through the lower hole 320a from the indoor space 210 side, and the tall nut is fixed from the outdoor space 220 side with a washer and a nut).

[0130] Figure 8B(i) shows a metal wall 300 to which a portion of the vertical mounting portion 130 and a portion of the lower mounting portion 140 are fixed, viewed from the interior space 210 side, and Figure 8B(ii) shows a metal wall 300 to which a portion of the vertical mounting portion 130 and a portion of the lower mounting portion 140 are fixed, viewed from the exterior space 220 side. A portion of the vertical mounting portion 130 and a portion of the lower mounting portion 140 are fixed to the metal wall 300 so as to protrude at least towards the interior space 210 side.

[0131] Next, as shown in Figure 8C, a heat-resistant layer 400 is laminated onto the surface of the metal wall 300 to which a portion of the vertical mounting portion 130 and a portion of the lower mounting portion 140 are fixed (specifically, the surface 311 on the interior space 210 side (see Figures 8A and 8B)). The heat-resistant layer 400 is not particularly limited as long as the effects of the present invention are obtained, but for example, it can be formed by applying and curing a fluid, amorphous heat-resistant composition.

[0132] As a result, as shown in Figure 8C, a portion of the vertical mounting portion 130 (shaft portion 134) and a portion of the lower mounting portion 140 (shaft portion 144), which were previously fixed to the metal wall 300, are embedded in the heat-resistant layer 400 with their ends on the interior space 210 side (the rear end X2 in the figure) exposed.

[0133] Subsequently, as shown in Figure 8D, the remaining portion of the vertical mounting portion 130 is connected to a part of the vertical mounting portion 130 that is fixed to the metal wall 300 and embedded in the heat-resistant layer 400, thereby completing the vertical mounting portion 130.

[0134] In this way, by fixing a part of the vertical mounting portion 130 and / or a part of the lower mounting portion 140 to the metal wall 300 before forming the heat-resistant layer 400 of the corner portion 100, the need to process the heat-resistant layer 400 in order to fix the vertical mounting portion 130 and / or the lower mounting portion 140 after the formation of the heat-resistant layer 400 is reduced, and the labor and time required in the manufacture of the heat-resistant structure 2 can be reduced more effectively.

[0135] Furthermore, if the corner portion 100 further has a heat-resistant surface layer 500 covering the surface of the heat-resistant layer 400 on the indoor section 210 side, as shown in Figure 3, the above preparation step may further include laminating the heat-resistant surface layer 500 onto the surface of the heat-resistant layer 400, as shown in Figure 8E. The heat-resistant surface layer 500 is not particularly limited as long as the effects of the present invention are obtained, but it is preferably an inorganic fiber (for example, an inorganic fiber blanket).

[0136] Subsequently, as shown in Figure 8F, the remaining portion of the lower mounting portion 140 is connected to a part of the lower mounting portion 140 that is fixed to the metal wall 300 and embedded in the heat-resistant layer 400, thereby completing the lower mounting portion 140. Specifically, first, a hole is formed in a part of the heat-resistant surface layer 500 corresponding to the lower end of a part of the lower mounting portion 140 to expose the lower end, and then the remaining portion of the lower mounting portion 140 is connected to the exposed lower end.

[0137] In the examples shown in Figures 8D to 8F, the vertical mounting portion 130 is completed first, followed by the completion of the lower mounting portion 140. However, the preparation steps are not limited to the above, as they include fixing a part of the vertical mounting portion 130 and / or a part of the lower mounting portion 140 to a metal wall 300 to which the heat-resistant layer 400 has not yet been laminated; laminating the heat-resistant layer 400 onto the surface of the metal wall 300 to which the vertical mounting portion 130 and / or a part of the lower mounting portion 140 are fixed; and, after the lamination of the heat-resistant layer 400, connecting the remaining part of the vertical mounting portion 130 and / or the remaining part of the lower mounting portion 140 to the part of the vertical mounting portion 130 and / or the part of the lower mounting portion 140 fixed to the metal wall 300.
