[Modes for carrying out the invention]

However, the dimensions, materials, shapes, relative arrangements, etc., of the components described as embodiments or shown in the drawings are not intended to limit the scope of the present invention, but are merely illustrative examples.

[0011] First, the configuration of several embodiments of exterior building material support structures will be described with reference to Figures 1 to 3. Hereinafter, the exterior building material support structure may be abbreviated as "support structure". Figure 1 is a cross-sectional view of an exterior building material support structure in the width direction of an exterior building material according to one embodiment. Figure 2 is a schematic diagram showing the state of a waterproof sealant before and after deformation according to one embodiment. The general shape of the waterproof sealant before deformation is shown by a dashed line, and the general shape of the waterproof sealant after deformation is shown by a solid line. Figure 3 is a cross-sectional view of an exterior building material support structure according to one embodiment, and is a cross-sectional view obtained by cutting the exterior building material support structure shown in Figure 1 along line AA.

[0012] The exterior building material support structure 1 is for supporting the exterior building material 2 that separates the interior and exterior of the building 9. As shown in Figure 1, the exterior building material 2 includes an exterior side surface 2a facing the exterior of the building 9 and an interior side surface 2b facing the interior of the building 9. In the embodiment shown in Figure 1, the exterior building material 2 is a lightweight aerated concrete (ALC) building material. In other embodiments not shown, the exterior building material 2 may be, for example, a window frame or an extruded cement board (ECP).

[0013] In some embodiments, as shown in FIGS. 1 and 3, the exterior building material support structure 1 includes a support concrete 3, an angle member 4 and a waterproof sealant 5 that extends along the width direction X2 of the exterior building material 2 on the support concrete 3. The waterproof sealant 5 is installed in a state of being sandwiched between the upper surface 31 of the support concrete 3 and the lower surface (the lower surface 42c of the first plate portion 42 described later) of the angle member 4 in the height direction X1 of the exterior building material 2. Note that the support concrete 3 may be, for example, a slab concrete that constitutes the building 9, or a beam concrete.

[0014] As shown in FIG. 1, the angle member 4 includes a first plate portion 42 that extends along the thickness direction X3 of the exterior building material 2, and a second plate portion 44 that extends along the indoor side surface 2b of the exterior building material 2. The second plate portion 44 is connected to the first plate portion 42 and extends along the height direction X1.

[0015] As shown in FIG. 1, the first plate portion 42 includes an outdoor end portion 42A on the outdoor side in the thickness direction X3 and an indoor end portion 42B on the indoor side in the thickness direction X3. In the embodiment shown in FIG. 1, the first plate portion 42 is connected to the second plate portion 44 at the indoor end portion 42B. That is, the angle member 4 has an L-shaped cross-sectional shape when viewed from the width direction X2. Thus, the angle member 4 may be, for example, an equal-leg angle steel or an unequal-leg angle steel. In other embodiments not shown, the first plate portion 42 may be connected to the second plate portion 44 at a position between the outdoor end portion 42A and the indoor end portion 42B in the thickness direction X3. That is, the angle member 4 may have a T-shaped cross-sectional shape when viewed from the width direction X2.

[0016] In some embodiments, the outdoor end portion 42A of the first plate portion 42 has an end surface 42a in the thickness direction X3. The end surface 42a of the first plate portion 42 is located on the indoor side of the outdoor side surface 2a of the exterior building material 2 and on the outdoor side of the indoor side surface 2b when viewed from the height direction X1. In the embodiment shown in FIG. 1, when the position of the indoor side surface 2b of the building exterior material 2 in the thickness direction X3 is set to 0% and the position of the outdoor side surface 2a is set to 100%, the end face 42a of the first plate portion 42 is located at a thickness direction position of 40% to 60%. In other embodiments not shown, the end face 42a of the first plate portion 42 may be located at the same position as the outdoor side surface 2a of the building exterior material 2 in the thickness direction X3.

[0017] At least a part of the first plate portion 42 is located between the upper surface 31 of the support concrete 3 and the lower surface 2c of the building exterior material 2 in the height direction X1 as described above. Therefore, the first plate portion 42 transmits the load received from the building exterior material 2 located above the first plate portion 42 to the support concrete 3 via the waterproof sealant 5. That is, the first plate portion 42 supports the building exterior material 2 in the height direction X1.

[0018] In the embodiments shown in FIGS. 1 and 3, the first plate portion 42 supports the building exterior material 2 via the filler 7. That is, the filler 7 is located between the first plate portion 42 and the lower surface 2c of the building exterior material 2 in the height direction X1. In the embodiments illustrated in FIGS. 1 and 3, the filler 7 is a refractory material. The type of the refractory material is not particularly limited, and for example, it may be rock wool. In other embodiments not shown, the first plate portion 42 directly supports the building exterior material 2. That is, the first plate portion 42 is arranged so as to directly contact the lower surface 2c of the building exterior material 2.

[0019] As shown in Figures 1 to 3, the waterproof sealant 5 installed on the upper surface 31 of the support concrete 3 is installed sandwiched between the upper surface 31 of the support concrete 3 and the lower surface 42c of the first plate portion 42. In other words, the waterproof sealant 5 is installed in a deformed state under a load X1 in the height direction from the first plate portion 42. More specifically, as shown in Figure 2, the waterproof sealant 5 viewed from the width direction X2 has a cross-sectional shape as shown by the dashed line before the first plate portion 42 is installed. Subsequently, with the installation of the first plate portion 42, the cross-sectional shape of the waterproof sealant 5 deforms, as shown by the solid line in Figure 2, by decreasing in height and widening in the thickness direction X3. The waterproof sealant 5 is not particularly limited and may be, for example, butyl rubber.

[0020] According to the above configuration, water can be prevented from entering the building from between the upper surface 31 of the support concrete 3 and the lower surface 42c of the first plate portion 42 of the angle member 4. Therefore, water can be effectively prevented from entering the building from the outside.

[0021] In the embodiments shown in Figures 1 to 3, the lower surface 42c of the first plate portion 42 is a flat surface that extends along the upper surface 31 of the support concrete 3. In other embodiments not shown, a recess may be provided in the lower surface 42c of the first plate portion 42. In this case, the depth of the recess in the lower surface 42c is shallower than the height of the waterproof sealant 5. By positioning the first plate portion 42 so that the waterproof sealant 5 is received in the recess in the lower surface 42c, the waterproof sealant 5 is sandwiched between the support concrete 3 and the first plate portion 42, and the positioning of the first plate portion 42 in the thickness direction X3 can be easily performed.

[0022] In the embodiment shown in Figure 1, the first plate portion 42 of the angle member 4 is fixed to the support concrete 3 by an anchor 8. The shaft portion 82 of the anchor 8 penetrates the first plate portion 42 along the height direction X1 and is fixed within a hole 33 provided in the support concrete 3, or within a hole 33 formed when the shaft portion 82 is driven into the support concrete 3. The head portion 84 of the anchor 8 abuts against the upper surface 42d of the first plate portion 42, fixing the first plate portion 42 in the height direction X1. The type of anchor 8 is not particularly limited and may be a metal anchor or an adhesive anchor.

[0023] According to the above configuration, the waterproof sealant 5 is more securely sandwiched between the upper surface 31 of the support concrete 3 and the lower surface 42c of the first plate portion 42, thereby improving the waterproof performance between the support concrete 3 and the first plate portion 42.

[0024] In the embodiment shown in Figure 1, the waterproof sealant 5 is located on the outdoor side of the anchor 8. That is, the indoor end face 5b of the waterproof sealant 5 in the thickness direction X3 is located on the outdoor side of the anchor 8 in the thickness direction X3.

[0025] According to the above configuration, water that penetrates between the support concrete 3 and the first plate portion 42 is less likely to reach the anchor 8. Therefore, deterioration of the anchor 8 can be prevented, and the durability of the support structure 1 can be improved.

[0026] In the embodiment shown in Figure 3, the waterproof sealant 5 includes a first portion 52 extending along the width direction X2 and a second portion 56 rising from the end 54 of the first portion 52 in the width direction X2.

[0027] As described above, the first part 51 is installed sandwiched between the upper surface 31 of the support concrete 3 and the lower surface 42c of the first plate part 42.

[0028] The second part 56 extends along the side surface 202 of the structure 200 adjacent to the support structure 1, as shown in Figure 3. In other words, the second part 56 extends along the height direction X1. The structure 200 is not particularly limited and may be, for example, the exterior wall or columns of building 9.

[0029] According to the above configuration, even if water accumulates outside building 9, water intrusion from the outside into the inside can be prevented more effectively. Therefore, the waterproofing performance of support structure 1 can be further improved.

[0030] In the embodiment shown in Figure 3, the end portion 54 of the first portion 52 abuts against the side surface 202 of the structure 200 adjacent to the exterior building material support structure 1. Furthermore, at least a portion of the second part 56 is located between the first plate portion 42 of the angle member 4 and the side surface 202 of the structure 200 in the width direction X2.

[0031] As shown in Figure 3, the height h of the second part 56 preferably satisfies the condition 0.25 ≤ h / H ≤ 1, where H is the distance between the lower surface 2c of the exterior building material 2 and the upper surface 31 of the supporting concrete 3. By satisfying the above condition, the second part 56 can more reliably prevent water from entering the building from the outside, even if water accumulates outside the building 9.

[0032] In the embodiment shown in Figure 1, the exterior building material support structure 1 may include a plate member 102 and a bolt 104 for fixing the plate member 102 to the indoor side surface 2b of the exterior building material 2. The plate member 102 is configured to sandwich the upper end portion 44D of the second plate portion 44, which is located above the height position of the lower surface 2c of the exterior building material 2, between the plate member 102 and the exterior building material 2 in the thickness direction X3. Thus, the exterior building material 2 is fixed in the thickness direction X3.

[0033] Next, with reference to Figures 1, 4, and 5, further configurations of exterior building material support structures according to several embodiments will be described. Figure 4 shows one embodiment in region B shown in Figure 1, and is a partially enlarged cross-sectional view of the exterior building material support structure. Figure 5 shows another embodiment in region B shown in Figure 1, and is a partially enlarged cross-sectional view of the exterior building material support structure.

[0034] In some embodiments, the exterior building material support structure 1 (1A, 1B) further includes at least one waterproof seal 20 (22, 24) installed on the outdoor side of the angle member 4, as shown in Figures 1, 4, and 5. That is, the indoor side surfaces 20b (22b, 24b) of the waterproof seal 20 (22, 24) are located on the outdoor side of the end face 42a of the first plate portion 42. The waterproof seal 20 (22, 24) also extends along the width direction X2 between the support concrete 3 and the exterior building material 2. The waterproof seals 20 (22, 24) are not particularly limited and may be made of polyurethane or silicone.

[0035] According to the above configuration, water is less likely to penetrate between the support concrete 3 and the first plate portion 42. Therefore, the waterproofing performance of the exterior building material support structure 1 (1A, 1B) can be further enhanced.

[0036] In the embodiments shown in Figures 1, 4, and 5, the indoor side surface 22b (20b) of the waterproof seal 22 (20) is in contact with the end surface 42a of the first plate portion 42. Therefore, even if water penetrates between the exterior building material 2 and the waterproof seal 20, it becomes difficult for water to penetrate between the angle member 4 and the supporting concrete 3. Furthermore, the indoor side surface 22b (20b) of the waterproof seal 22 (20) may be in contact with the end surface 5a of the waterproof sealing material 5.

[0037] In the embodiments shown in Figures 1, 4, and 5, the lower surfaces 20c (22c, 24c) of the waterproof seals 20 (22, 24) are adhered to the upper surface 31 of the support concrete 3. Similarly, the upper surfaces 20d (22d, 24d) of the waterproof seals 20 (22, 24) are adhered to the lower surface 2c of the exterior building material 2. As a result, water is less likely to penetrate between the support concrete 3 and the first plate portion 42.

[0038] In the embodiments shown in Figures 1, 4, and 5, the waterproof seal 20 includes a pair of waterproof seals 22 and 24 that are installed side by side in the thickness direction X3. That is, one waterproof seal 22 and the other waterproof seal 24 are separate entities and are arranged side by side in the thickness direction X3. One waterproof seal 22 is installed between the end face 42a of the first plate portion 42 and the indoor side surface 24b of the other waterproof seal 24 in the thickness direction X3. In other words, the other waterproof seal 24 is installed on the outdoor side than the outdoor side surface 22a of the one waterproof seal 22. Furthermore, the one waterproof seal 22 and the other waterproof seal 24 may be arranged in contact with each other or spaced apart in the thickness direction X3. The pair of waterproof seals 22 and 24 may be made of the same material or of different materials.

[0039] According to the above configuration, the possibility of the waterproof seals 22 and 24 rupturing due to pulling on each other in the event of lateral shaking such as an earthquake can be reduced. Therefore, the durability of the exterior building material support structure 1 (1A, 1B) can be increased.

[0040] In one embodiment (not shown), the pair of waterproof seals 22 and 24 are arranged so as not to adhere to each other. In other words, the pair of waterproof seals 22 and 24 are not bonded together with an adhesive or the like.

[0041] In the embodiments shown in Figures 1 and 4, the pair of waterproof seals 22 and 24 are arranged such that one waterproof seal 22 is spaced apart from the other waterproof seal 24. That is, the outdoor side surface 22a of one waterproof seal 22 and the indoor side surface 24b of the other waterproof seal 24 are spaced apart by a distance X in the thickness direction X3. In this case, a gap G is formed between the pair of waterproof seals 22 and 24.

[0042] According to the above configuration, the possibility of the waterproof seals 22 and 24 being damaged by rubbing against each other in the event of lateral shaking such as an earthquake can be reduced. Therefore, the durability of the exterior building material support structure 1(1A) can be further enhanced.

[0043] Furthermore, it is preferable that the distance X between the outdoor side surface 22a of one waterproof seal 22 and the indoor side surface 24b of the other waterproof seal 24 be 10 mm or less. If the distance X is too large, the gap G may become a place where water accumulates. Water accumulated in the gap G may cause mold to grow and deterioration of surrounding components, so by making the distance X 10 mm or less, the possibility of mold growth and deterioration of surrounding components can be suppressed.

[0044] In the embodiment shown in Figure 5, the exterior building material support structure 1B further includes a backup material 30 installed between a pair of waterproof seals 22 and 24. Specifically, the backup material 30 is installed between the outdoor side surface 22a of one waterproof seal 22 and the indoor side surface 24b of the other waterproof seal 24.

[0045] According to the above configuration, the possibility of the waterproof seals 22 and 24 being damaged by rubbing against each other in the event of lateral shaking such as an earthquake can be reduced. Therefore, the durability of the exterior building material support structure 1(1B) can be further enhanced.

[0046] In the embodiment shown in Figure 5, the backup material 30 is made of a material that does not easily adhere to both of the pair of waterproof seals 22 and 24. Therefore, the outdoor side surface 30a of the backup material 30 and the indoor side surface 24b of the waterproof seal 24 are not adhered to each other. Similarly, the indoor side surface 30b of the backup material 30 and the outdoor side surface 22a of the waterproof seal 22 are not adhered to each other. Therefore, in the event of lateral shaking such as an earthquake, the waterproof seals 22 and 24 can be pulled against each other via the backup material 30, thereby reducing the possibility of the waterproof seals 22 and 24 rupturing. The material of the backup material 30 is not particularly limited and may be polyethylene, for example. The backup material 30 may be a sponge with air bubbles formed inside. Since the sponge used as the backup material 30 has cushioning properties, the compressed backup material 30 can be installed between the upper surface 31 of the support concrete 3 and the lower surface 2c of the exterior building material 2. In this case, the restoring force of the backup material 30 acts on the support concrete 3 and the exterior building material 2 along the height direction X1, so the backup material 30 can be easily fixed in place.

[0047] In some embodiments, the exterior building material support structure 1 (1A, 1B), as shown in Figures 1, 4, and 5, further includes a waterproof membrane 60 extending from the upper surface 31 of the support concrete 3 on the outdoor side along the height direction X1 of the exterior building material 2. The waterproof membrane 60 includes a vertical attachment portion 62 that is attached to the outdoor side surface 2a of the exterior building material 2.

[0048] According to the above configuration, the gap between the exterior building material 2 and the supporting concrete 3 can be sealed. Therefore, the waterproofing of the exterior building material support structure 1 (1A, 1B) can be further enhanced.

[0049] In the embodiments shown in Figures 1, 4, and 5, the vertical attachment portion 62 has a first surface 62b facing the outdoor side surface 2a of the exterior building material 2, and is attached to the outdoor side surface 2a of the exterior building material 2 on the first surface 62b.

[0050] In the embodiments shown in Figures 1, 4, and 5, the vertical attachment portion 62 is located below the first surface 62b and further includes a second surface 62c facing the waterproof seal 24(20). The vertical attachment portion 62 is attached to the outdoor side surface 24a(20a) of the waterproof seal 24(20) on the second surface 62c. By attaching the vertical attachment portion 62 to the exterior building material 2 and the waterproof seal 24(20), water intrusion between the exterior building material 2 and the waterproof seal 24(20), and between the waterproof seal 24(20) and the supporting concrete 3 can be prevented more effectively.

[0051] In some embodiments, as shown in Figures 1, 4, and 5, the waterproof membrane 60 extends from the lower end 62C of the vertical attachment portion 62 toward the outdoors and further includes a horizontal attachment portion 64 that is attached to the upper surface 31 of the support concrete 3.

[0052] According to the above configuration, water intrusion along the upper surface 31 of the support concrete 3 can be prevented more effectively. Therefore, the waterproofing performance of the exterior building material support structure 1 (1A, 1B) can be further improved.

[0053] The waterproof membrane 60 may be a sheet-like sealing material or a membrane formed by the solidification of a liquid waterproofing agent. Furthermore, since the waterproof membrane 60 is exposed to sunlight and rainfall, high waterproofness and weather resistance are required. Therefore, the waterproof membrane 60 is preferably a urethane-based coating.

[0054] The characteristic configurations of the exterior building material support structures 1 (1A, 1B) according to some of the embodiments described above can be summarized as follows.

[0055] [1] Exterior building material support structures (1(1A, 1B)) according to several embodiments are, An exterior building material support structure (1(1A, 1B)) that supports exterior building materials (2) that separate the interior and exterior of a building (9), Supporting concrete (3) and An angle member (4) extending along the width direction (X2) of the exterior building material (2) on the supporting concrete (3), the angle member (4) includes a first plate portion (42) extending in the thickness direction (X3) of the exterior building material (2) and for supporting the exterior building material (2), and a second plate portion (44) extending along the indoor side surface (2b) of the exterior building material (2), A waterproof sealant (5) extending along the width direction (X2) on the supporting concrete (3), the waterproof sealant (5) being installed sandwiched between the upper surface (31) of the supporting concrete (3) and the lower surface (42c) of the first plate portion (42), It is equipped with.

[0056] According to the configuration described in [1] above, the waterproof sealant (5) is installed sandwiched between the upper surface (31) of the support concrete (3) and the lower surface (42c) of the first plate portion (42) of the angle member (4), thereby preventing water from entering the building from the gap between the upper surface (31) of the support concrete (3) and the lower surface (42c) of the first plate portion (42) of the angle member (4). Therefore, it is possible to effectively prevent water from entering the building from the outside while reducing the construction man-hours for the exterior building material support structure.

[0057] [2] In some embodiments, in the configuration of [1] above, The first plate portion (42) of the angle member (4) is fixed to the supporting concrete (3) by an anchor (8).

[0058] According to the configuration described in [2] above, the first plate portion (42) is fixed to the supporting concrete (3) by the anchor (8), so that the waterproof sealant (5) is more securely sandwiched between the upper surface (31) of the supporting concrete (3) and the lower surface (42c) of the first plate portion (42). Therefore, the waterproof performance between the supporting concrete (3) and the first plate portion (42) can be improved.

[0059] [3] In some embodiments, in the configuration of [2] above, The waterproof sealant (5) is located on the outdoor side of the anchor (8).

[0060] According to the configuration described in [3] above, the waterproof sealant (5) is installed on the outdoor side of the anchor (8), so water that enters between the supporting concrete (3) and the first plate (42) from the outside is less likely to reach the anchor (8). Therefore, deterioration of the anchor (8) can be prevented, and the durability of the exterior building material support structure (1 (1A, 1B)) can be improved.

[0061] [4] In some embodiments, in any of the configurations described in [1] to [3] above, The waterproof sealant (5) is The first portion (52) extends along the width direction (X2) and is installed sandwiched between the upper surface (31) of the supporting concrete (3) and the lower surface (42c) of the first plate portion (42), A second portion (56) rises from the end (54) of the first portion (52) in the width direction (X2) and extends along the side (202) of the adjacent structure (200), Includes.

[0062] According to the configuration described in [4] above, the waterproof sealant (5) includes a second portion (56) that extends along the side (202) of the adjacent structure (200), so that even if water accumulates outside the building (9), water intrusion from the outside into the inside can be prevented more effectively. Therefore, the waterproofing performance of the exterior building material support structure (1(1A, 1B)) can be further improved.

[0063] [5] In some embodiments, in any of the configurations [1] to [4] above, the exterior building material support structure (1(1A, 1B)) is, The structure further includes at least one waterproof seal (20(22, 24)) that extends along the width direction (X2) between the supporting concrete (3) and the exterior building material (2), and is installed on the outdoor side of the angle member (4).

[0064] According to the configuration described in [5] above, at least one waterproof seal (20(22, 24)) is installed on the outdoor side of the angle member (4), making it difficult for water to penetrate between the supporting concrete (3) and the first plate (42). Therefore, the waterproofing of the exterior building material support structure (1(1A, 1B)) can be further enhanced.

[0065] [6] In some embodiments, in the configuration of [5] above, At least one waterproof seal (20) includes a pair of waterproof seals (22, 24) installed side by side in the thickness direction (X3).

[0066] When multiple waterproof seals are bonded together in the thickness direction (X3), there is a risk that the waterproof seals may pull against each other due to lateral shaking such as earthquakes. This pulling against each other may cause the waterproof seals to rupture, potentially reducing the waterproofing performance of the exterior building material support structure. In this regard, according to the configuration described in [6] above, since the pair of waterproof seals (22, 24) are installed side by side in the thickness direction (X3), the possibility of the waterproof seals (22, 24) pulling on each other and breaking in the event of lateral shaking such as an earthquake can be reduced. Therefore, the durability of the exterior building material support structure (1(1A, 1B)) can be increased.

[0067] [7] In some embodiments, in the configuration of [6] above, The pair of waterproof seals (22, 24) are installed such that one waterproof seal (22) is spaced apart from the other waterproof seal (24).

[0068] According to the configuration described in [7] above, one waterproof seal (22) is installed spaced apart from the other waterproof seal (24), so the pair of waterproof seals (22, 24) do not come into contact with each other. Therefore, in the event of lateral shaking such as an earthquake, the possibility of the waterproof seals (22, 24) rubbing against each other and being damaged is reduced. Consequently, the durability of the exterior building material support structure (1(1A)) can be further enhanced.

[0070] According to the configuration described in [8] above, a backup material (30) is installed between the pair of waterproof seals (22, 24), so that the pair of waterproof seals (22, 24) do not come into contact with each other. Therefore, in the event of lateral shaking such as an earthquake, the possibility of the waterproof seals (22, 24) rubbing against each other and being damaged can be reduced. Thus, the durability of the exterior building material support structure (1(1B)) can be further enhanced.

[0071] [9] In some embodiments, in any of the configurations [1] to [8] above, the exterior building material support structure (1(1A, 1B)) is, A waterproof membrane (60) extending from the upper surface (31) of the supporting concrete (3) along the height direction (X1) of the exterior building material (2) on the outdoor side, further comprising a waterproof membrane (60) including a vertical attachment portion (62) that is attached to the outdoor side surface (2a) of the exterior building material (2).

[0072] According to the configuration described in [9] above, the vertical attachment portion (62) of the waterproof membrane (60) is attached to the outdoor side surface (2a) of the exterior building material (2), thereby sealing the gap between the exterior building material (2) and the supporting concrete (3). Therefore, the waterproofing performance of the exterior building material support structure (1 (1A, 1B)) can be further enhanced.

[0073]

[10] In some embodiments, in the configuration of [9] above, The waterproof membrane (60) extends outward from the lower end (62C) of the vertical attachment portion (62) and further includes a horizontal attachment portion (64) that is attached to the upper surface (31) of the supporting concrete (3).

[0074] According to the configuration described in

[10] above, the horizontal attachment portion (64) extends from the lower end (62C) of the vertical attachment portion (62) toward the outside, so that water intrusion along the upper surface (31) of the supporting concrete (3) can be prevented more effectively. Therefore, the waterproofing performance of the exterior building material support structure (1 (1A, 1B)) can be further improved.

[0075] Although several embodiments of the present invention have been described above, it goes without saying that modifications to the above embodiments are permitted as long as they do not deviate from the spirit of the present invention.

[0076] In this specification, expressions describing relative or absolute arrangements such as "in a certain direction," "along a certain direction," "parallel," "orthogonal," "center," "concentric," or "coaxial" shall not only describe such arrangements strictly, but also describe states of relative displacement with tolerances or angles or distances that allow for the same function to be achieved. For example, expressions such as "identical," "equal," and "homogeneous" that describe things being in an equal state not only describe a state of being strictly equal, but also describe a state in which there is a tolerance or a difference that is sufficient to achieve the same function. Furthermore, in this specification, expressions describing shapes such as quadrilaterals and cylindrical shapes shall not only represent geometrically precise quadrilaterals and cylindrical shapes, but also shapes that include uneven surfaces, chamfered surfaces, etc., to the extent that the same effect can be achieved. Furthermore, in this specification, the expressions “equipment,” “includes,” or “possess” of a component are not exclusive expressions that exclude the existence of other components.
