[0009] Hereinafter, one embodiment of a support body and a building substructure according to the present disclosure will be described with reference to FIGS. 1 to 6. FIG. 1 and 2, the supports 10 and 20 of this embodiment are used in a substructure (hereinafter simply referred to as a substructure) 2 of a building 1. That is, in this embodiment, the substructure 2 includes multiple types of supports 10 and 20. The substructure 2 comprises supports 10, 20, precast concrete bodies 40, 45, and a plurality of vertical wall members 50.

[0010] As shown in Figure 2, a depression G2 is formed in the ground G1 in accordance with the shape of the substructure 2. For example, the substructure 2 has a rectangular outer edge shape in plan view (when viewed from above). Similarly, the depression G2 has a rectangular outer periphery shape in plan view. In this example, a bed mortar (mortar) 100 is placed on the bottom surface (ground surface) G3 of the depression G2. Note that the building 1 does not necessarily need to be provided with the bed mortar 100.

[0011] As shown in FIGS. 1 and 2, the support 10 includes a bottom portion 11 and a support portion 16 . The bottom 11 is formed into a plate shape using a steel plate or the like. In this example, the bottom 11 has a rectangular shape when viewed along the thickness direction of the bottom 11. Here, "A is along B" means that the angle formed between A and B is 30 degrees or less. It is more preferable that this angle be 15 degrees or less. The bottom portion 11 is placed on the bottom surface G3 via the bed mortar 100. That is, the bottom portion 11 is disposed so that the thickness direction of the bottom portion 11 is along the vertical direction Z.

[0012] Here, in the plan view shown in FIG. 1 , the direction along the first side 11a of the bottom 11 is defined as the first direction X. In the plan view, the direction along the second side 11b of the bottom 11 is defined as the second direction Y. The second direction Y is a direction perpendicular to the first direction X. The up-down direction Z is a direction perpendicular to both the first direction X and the second direction Y.

[0013] In plan view, the direction of the first direction X from the inside to the outside of the lower structure 2 is defined as the first side X1 (one side; hereinafter simply referred to as the first side X1). In plan view, the direction of the first direction X from the outside to the inside of the lower structure 2 is defined as the second side X2 (the other side; hereinafter simply referred to as the second side X2). In a plan view, one side of the second direction Y is defined as a first side Y1 (hereinafter simply referred to as the first side Y1), and the other side of the second direction Y is defined as a second side Y2 (hereinafter simply referred to as the second side Y2). In the following, directions relative to the support body 20, the precast concrete bodies 40, 45, the vertical wall member 50, etc. are defined by the first direction X, the second direction Y, etc. in the support body 10.

[0014] The shape of the bottom 11 when viewed along the thickness direction of the bottom 11 is not limited to a rectangular shape, but may be a triangular shape, a hexagonal shape, or the like.

[0015] 1 and 2, the support portion 16 is erected upward in the vertical direction Z (hereinafter referred to as "upward") from the bottom portion 11. The support portion 16 supports the vertical wall member 50. Specifically, the support portion 16 includes a pair of plate-like bodies 17, 18. The plate-like bodies 17, 18 are each formed into a plate shape using a steel plate or the like, and are arranged such that the thickness direction of the plate-like bodies 17, 18 is aligned with the first direction X. In this example, when viewed along the thickness direction of the plate-like bodies 17, 18, the plate-like bodies 17, 18 each have a rectangular shape.

[0016] The plate-like bodies 17 and 18 are arranged to face each other in the first direction X. That is, a gap S1 is formed between the plate-like body 17 and the plate-like body 18 (see FIG. 2). The plate-like body 17 is arranged on the first side X1 with respect to the plate-like body 18. In this example, the plate-like body 18 stands upward from the end of the second side X2 of the bottom portion 11. The plate-like body 17 stands upward from the middle of the bottom portion 11 in the first direction X. 1, the positions of the ends of the first side Y1 of the bottom 11, the first side Y1 of the plate-like body 17, and the first side Y1 of the plate-like body 18 are aligned in the second direction Y. The positions of the ends of the second side Y2 of the bottom 11, the second side Y2 of the plate-like body 17, and the second side Y2 of the plate-like body 18 are aligned in the second direction Y.

[0017] The plate-like bodies 17 and 18 are connected to the bottom 11 by welding or the like in a state spaced apart from each other so as to sandwich the vertical wall arrangement reference line L therebetween. Next, the vertical wall member 50 will be described. 1 and 2, the vertical wall member 50 is formed in a plate shape from concrete, reinforced concrete, or the like. The thickness direction of the vertical wall member 50 is the first direction X. In this example, when viewed along the thickness direction of the vertical wall member 50, the vertical wall member 50 has a rectangular shape. The plate-like bodies 17, 18 provided on the support portion 16 of the support body 10 support the vertical wall member 50 in a state where the vertical wall member 50 is sandwiched between the plate-like bodies 17, 18 in the first direction X. The vertical wall member 50 protrudes upward beyond the upper ends of the plate-like bodies 17, 18.

[0018] As shown in Figure 1, here, in a plan view, a reference line L1 is defined that is perpendicular to the direction (first direction X) in which the plate-like bodies 17 and 18 of the support portion 16 sandwich the vertical wall member 50 and passes through the center between the plate-like bodies 17 and 18. In this embodiment, the support portion 16 is arranged linearly in a plan view. Here, "the support portion 16 is arranged linearly in a plan view" means that the reference line L1 corresponding to the support portion 16 is linear in a plan view. In this way, the reference line L1 forms a single continuous vertical wall arrangement reference line L that is linear in a plan view. In a plan view, the support portion 16 is arranged along the vertical wall arrangement reference line L. Here, A being along B means that the angle formed by A and B is 30 degrees or less. It is more preferable that this angle be 15 degrees or less.

[0019] As shown in FIGS. 1 and 3, the support 20 includes a bottom portion 21 and support portions 26 and 31. 3, the bottom portion 21 has the same structure as the bottom portion 11. In this example, when viewed along the thickness direction of the bottom portion 21, the bottom portion 21 has a rectangular shape.

[0020] The support portions 26, 31 are erected upward from the bottom portion 21. The support portions 26, 31 support the vertical wall member 50. The support body 20 includes, as support portions, the support portions 26, 31, which are a plurality of support portions spaced apart from each other along the vertical wall arrangement reference line L. Specifically, the support portion 26 includes a pair of plate-like bodies 27, 28. The plate-like bodies 27, 28 are each formed into a plate shape using a steel plate or the like, and are arranged such that the thickness direction of the plate-like bodies 27, 28 is along the first direction X. In this example, when viewed along the thickness direction of the plate-like bodies 27, 28, the plate-like bodies 27, 28 each have a rectangular shape.

[0021] The plate-like bodies 27 and 28 are arranged to face each other in the first direction X. That is, a gap S3 is formed between the plate-like bodies 27 and 28. The plate-like body 27 is arranged closer to the first side X1 than the plate-like body 28. In this example, the plate-like bodies 27 and 28 are erected upward from the middle of the bottom portion 21 in the first direction X. The positions of the ends of the first side Y1 of the bottom 21, the first side Y1 of the plate-like body 27, and the first side Y1 of the plate-like body 28 are aligned in the second direction Y. The ends of the second sides Y2 of the plate-like body 27 and the second side Y2 of the plate-like body 28 are located in the middle of the bottom 21 in the second direction Y.

[0022] The support part 31 includes a pair of plate-like bodies 32, 33. The plate-like bodies 32, 33 are each formed into a plate shape using a steel plate or the like, and are arranged so that the thickness direction of the plate-like bodies 32, 33 is along the second direction Y. In this example, when viewed along the thickness direction of the plate-like bodies 32, 33, each of the plate-like bodies 32, 33 has a rectangular shape.

[0023] The plate-like bodies 32 and 33 are arranged to face each other in the second direction Y. That is, a gap S4 is formed between the plate-like bodies 32 and 33. The plate-like body 32 is arranged closer to the first side Y1 than the plate-like body 33. In this example, the plate-like bodies 32 and 33 are erected upward from the middle of the bottom portion 21 in the second direction Y. The positions of the ends of the second side X2 of the bottom 21, the plate-like body 32, and the plate-like body 33 coincide in the first direction X. The ends of the first side X1 of the plate-like body 32 and the plate-like body 33 are located in the middle of the bottom 21 in the first direction X. The ends of the plate-like bodies 32 and 33 on the first side X1 are disposed closer to the second side X2 and the second side Y2 than the ends of the plate-like bodies 27 and 28 on the second side Y2. In other words, the plate-like bodies 32 and 33 are spaced apart.

[0024] The plate-like bodies 27, 28, 32, and 33 are connected to the bottom portion 21 by welding or the like. The plate-like bodies 27, 28 included in the support portion 26 of the support body 20 support the vertical wall member 50 in a state in which it is sandwiched between the plate-like bodies 27, 28 in the first direction X. The plate-like bodies 32, 33 included in the support portion 31 of the support body 20 support the vertical wall member 50 in a state in which it is sandwiched between the plate-like bodies 32, 33 in the second direction Y.

[0025] Here, in plan view, a reference line L3 is defined that is perpendicular to the direction in which the plate-like bodies 27, 28 of the support portion 26 sandwich the vertical wall member 50 (first direction X) and passes through the center between the plate-like bodies 27, 28. In plan view, a reference line L4 is defined that is perpendicular to the direction in which the plate-like bodies 32, 33 of the support portion 31 sandwich the vertical wall member 50 (second direction Y) and passes through the center between the plate-like bodies 32 and 33. The support portions 26, 31 are arranged in an L-shape in a plan view. Here, "the support portions 26, 31 are arranged in an L-shape in a plan view" means that the reference lines L3, L4 corresponding to the support portions 26, 31 are L-shaped in a plan view. In this way, the reference lines L3 and L4 form a single continuous vertical wall arrangement reference line L that is L-shaped in a plan view. Note that the angle θ1 formed by the reference lines L3 and L4 is not limited as long as it is greater than 0° and less than 180°.

[0026] As shown in FIG. 1, the vertical wall member 50 supported by the support portion 26 and the vertical wall member 50 supported by the support portion 31 are connected to each other.

[0027] 1 and 2, the precast concrete bodies 40, 45 are L-channel shaped. That is, when viewed along the longitudinal direction of the precast concrete body 40, the precast concrete body 40 has an L-shaped trench shape. The precast concrete body 45 is similar to the precast concrete body 40. The precast concrete molded body 40 includes a bottom wall portion (bottom portion) 41 and vertical wall portions 42. The bottom wall portion 41 and the vertical wall portions 42 are each formed in a plate shape.

[0028] When viewed along the thickness direction of the bottom wall portion 41, the bottom wall portion 41 has a rectangular shape. The bottom wall portion 41 is arranged so that the thickness direction of the bottom wall portion 41 is along the vertical direction Z. As shown in FIG. 2, the lower surface (first surface) 41a of the bottom wall portion 41 is along a horizontal plane. The lower surface 41a becomes the bottom surface of the precast concrete molded body 40. The vertical wall portion 42 stands upward from the end of the first side X1 of the bottom wall portion 41. The surface of the vertical wall portion 42 facing the first side X1 is an L-shaped second surface 42a. The second surface 42a is along a vertical plane. For example, the length of the vertical wall portion 42 in the up-down direction Z is 2 m.

[0029] The precast concrete body 40 is positioned so that its L-shaped lower surface 41a is the bottom surface along the horizontal plane. The bottom 11 of the support body 10 is positioned in a stacked state below the lower surface 41a of the precast concrete body 40. The bottom wall portion 41 and the vertical wall portion 42 of the precast concrete molded body 40 are integrally formed from concrete.

[0030] As shown in Figure 1, the precast concrete molded body 45 is for use in the corner of the substructure 2. As shown in Figures 1 and 4, the precast concrete molded body 45 includes a bottom wall portion 46, a first vertical wall portion 47, and a second vertical wall portion 48. The bottom wall portion 46, the first vertical wall portion 47, and the second vertical wall portion 48 are each formed in a plate shape.

[0031] When viewed along the thickness direction of the bottom wall portion 46, the bottom wall portion 46 has a rectangular shape. The bottom wall portion 41 is disposed so that the thickness direction of the bottom wall portion 41 is along the vertical direction Z. A notch 46a is formed in a corner of the bottom wall portion 41 on the second side X2 and the first side Y1. The notch 46a penetrates the bottom wall portion 46 in the vertical direction Z. The first vertical wall portion 47 stands upward from the end of the bottom wall portion 46 on the first side X1. The second vertical wall portion 48 stands upward from the end of the second side Y2 of the bottom wall portion 46. The end of the second vertical wall portion 48 on the first side X1 is continuous with the first vertical wall portion 47. The bottom wall portion 46, the first vertical wall portion 47, and the second vertical wall portion 48 of the precast concrete molded body 45 are integrally formed from concrete.

[0032] The upper end of the first vertical wall portion 47, the upper end of the second vertical wall portion 48, and the upper end of the vertical wall portion 42 of the precast concrete molded body 40 are located at the same height. As shown in FIG. 1, the upper end of the vertical wall portion 42 is disposed above the upper end of the vertical wall member 50 .

[0033] 1, the support body 20 and the precast concrete molded body 45 are arranged in a corner of the substructure 2 in a plan view. At this time, the bottom 21 of the support body 20 is arranged in a stacked state below the bottom wall portion 46 of the precast concrete molded body 45. The precast concrete bodies 40 are arranged side by side on the first side Y1 and the second side X2 of the precast concrete bodies 45. The vertical wall member 50 supported by the support portions 26, 31 of the support body 20 is engaged with the notch 46a of the bottom wall portion 46 from the second side X2 and the first side Y1 of the notch 46a.

[0034] In this embodiment, the lower structure 2 includes a plurality of supports 10. Some of the supports 10 (hereinafter also referred to as supports 10A) support the ends of two vertical wall members 50 aligned in the second direction Y. That is, the two vertical wall members 50 supported by the support 10A are both arranged on the same straight line in a plan view and are connected to each other in the second direction Y. The bottom 11 of the support 10A is arranged in a stacked state below the bottom wall portions 41 of two precast concrete molded bodies 40 arranged side by side in the second direction Y. As shown in Figure 2, it is preferable that the plate-like body 17 of the support 10A contacts the bottom wall portions 41 of the precast concrete molded bodies 40 from the second side X2 rather than the bottom wall portions 41.

[0035] 1, the remaining portions of the multiple supports 10 (hereinafter also referred to as supports 10B) support the ends of two vertical wall members 50 aligned in the first direction X. That is, the two vertical wall members 50 supported by the support 10B are both arranged on the same straight line in a plan view and are connected to each other in the first direction X. The bottom portion 11 of the support body 10B is arranged in a stacked state below the bottom wall portions 41 of two precast concrete bodies 40 arranged in the first direction X.

[0036] The support body 10 may support only one vertical wall member 50. The support 10 includes a single support portion 16 for supporting one vertical wall member 50 or a plurality of vertical wall members 50 connected to one another. The support body 20 is provided with a plurality of (two) support parts 26, 31 in order to support two vertical wall members 50 that are connected to each other in a state where their arrangement postures intersect in a plan view. That is, the support body 20 is provided with a plurality of support parts 26, 31 that are spaced apart from each other along the vertical wall arrangement reference line L, and these support parts 26 and support parts 31 share the burden of supporting each of the plurality of vertical wall members 50 that are connected to each other.

[0037] As shown in Fig. 2, the first side X1 of the vertical wall member 50 is filled with concrete 105. The concrete 105 is filled between the vertical wall member 50 and the vertical wall portion 42 of the precast concrete molded body 40, above the bottom wall portion 41. The concrete 105 is filled up to the upper end of the vertical wall member 50. The second side X2 of the vertical wall member 50 is filled with earth and stones 107. Here, the earth and stones 107 refers to soil (which may be at least one of clay, leaf mold, and sand), stone (which may be crushed stone), or a mixture thereof. The earth and stones 107 may be excavated soil (excavated soil) that has been returned, or may be soil dressing. The particle size of the soil is not limited.

[0038] The vertical wall member 50 is supported by the support portions 16, 26, 31 of the supports 10, 20 in a state where it is sandwiched between concrete 105 and earth and stone 107 in the first direction X. The entire support portions 16, 26, 31 and the entire vertical wall member 50 are buried below (under the floor) a floor 109. The upper surface of the floor 109 is the floor level 109a. The floor level 109 a is located below the upper end of the vertical wall portion 42 of the precast concrete molded body 40 .

[0039] The vertical wall portion 42 of the precast concrete molded body 40 has a portion located at a height equal to or higher than the floor level 109a. The vertical wall portion 42 forms a part of the spandrel wall 111 of the building 1. Note that a heat insulating material may be placed below the floor 109.

[0040] Next, an outline of a construction method for the substructure 2 configured as above will be described. A depression G2 is formed in the ground G1 according to the shape of the building 1 to be constructed. The support body 20 is placed in the recess G2 at a corner of the lower structure 2 in plan view. A precast concrete molded body 45 is stacked (placed) above the bottom 21 of the support body 20. The supports 10 are arranged in the recess G2 at predetermined intervals. Precast concrete molded bodies 40 are stacked above the bottoms 21 of the supports 20 and above the bottoms 11 of the supports 10. The vertical wall member 50 is supported by the support portions 16, 26, 31 of the supports 10, 20. By carrying out the above steps, the substructure 2 is constructed.

[0041] As described above, in the support body 10 of this embodiment, the vertical wall member 50 is supported by the support portions 16 arranged along a single continuous vertical wall arrangement reference line L that is linear in plan view. Since only the support portions 16 that support the vertical wall member 50 and are arranged along the single continuous vertical wall arrangement reference line L are arranged on the bottom portion 11, it is possible to easily arrange members other than the support body 10 on the bottom portion 11. Therefore, it is possible to easily construct the support body 10.

[0042] The support body 20 has, as support parts, support parts 26, 31 that are spaced apart from each other along the vertical wall arrangement reference line L. This reduces the amount of material required to configure the support parts 26, 31 and makes it possible to suppress the cost required to manufacture the support parts 26, 31, compared to when the support parts are arranged continuously and without gaps along the vertical wall arrangement reference line. The plate-like bodies 17, 18 support the vertical wall member 50 in a state where it is sandwiched between the plate-like bodies 17, 18 in the first direction X. Therefore, the plate-like bodies 17, 18 can reliably support the vertical wall member 50 in a state where it is sandwiched between the plate-like bodies 17, 18.

[0043] The first side X1 of the vertical wall member 50 is filled with concrete 105, and the second side X2 of the vertical wall member 50 is filled with earth and stones 107, and the entire support portion 16 and the entire vertical wall member 50 are buried below the floor 109. This allows the support body 10 to be buried without being removed or dismantled, and the number of steps required to construct the support body 10 can be reduced. Furthermore, in the substructure 2 of this embodiment, the vertical wall member 50 can be supported by the support portion 16. Then, by placing the lower surface 41a of the precast concrete molded body 40 on the bottom portion 11 of the support body 10, the precast concrete molded body 40 can hold the position of the support body 10.

[0044] The precast concrete molded body 40 has a vertical wall portion 42, and the vertical wall portion 42 has a portion located at a height equal to or higher than the floor level 109a. Therefore, the upper end of the vertical wall portion 42 can be made to protrude above the floor level 109a. The vertical wall portion 42 forms a part of the waist wall 111 of the building 1. Therefore, the vertical wall portion 42 can form a part of the waist wall 111 of the building 1.

[0045] The support bodies 10 and 20 of this embodiment can have various modifications in their configuration, as will be described below. 5 includes support portions 16A and 16B instead of the support portion 16 in each configuration of the support portion 10. That is, the support portion 10A includes support portions 16A and 16B, which are a plurality of support portions spaced apart from each other along the vertical wall arrangement reference line L. The support portion 16A includes plate-like bodies 17A and 18A. Similar to the plate-like bodies 17 and 18, the plate-like bodies 17A and 18A are erected on the bottom portion 11 spaced apart from each other and sandwiching the vertical-wall placement reference line L. The support portion 16B includes plate-like bodies 17B and 18B. Similar to the plate-like bodies 17 and 18, the plate-like bodies 17B and 18B are erected on the bottom portion 11 spaced apart from each other and sandwiching the vertical-wall placement reference line L. The plate-like body 17A and the plate-like body 17B are arranged at an interval from each other in the second direction Y. The plate-like body 18A and the plate-like body 18B are arranged at an interval from each other in the second direction Y.

[0046] That is, the support portion 16 is divided into two in the second direction Y to form the support portions 16A and 16B.

[0047] Here, a reference line L6 is defined which, in plan view, is perpendicular to the direction (first direction X) in which the plate-like bodies 17A and 18A of the support part 16A sandwich the vertical wall member 50 therebetween and passes through the center between the plate-like body 17A and the plate-like body 18A. The reference line L6 coincides with a reference line which, in plan view, is perpendicular to the direction (first direction X) in which the plate-like bodies 17B and 18B of the support part 16B sandwich the vertical wall member 50 therebetween and passes through the center between the plate-like body 17B and the plate-like body 18B. The support portion 16A and the support portion 16B are arranged linearly as a whole in a plan view. This is because the reference line L6 corresponding to each of the support portion 16A and the support portion 16B is linear in a plan view. In this way, the reference line L6 forms a single continuous vertical wall arrangement reference line L that is linear in a plan view, and the support portions 16A and 16B as multiple support portions are arranged along the single continuous vertical wall arrangement reference line L that is linear in a plan view.

[0048] The support 10A of the first modified example configured as above can also achieve the same effects as the support 10 of this embodiment. The support portion 16 may be divided into three or more portions in the second direction Y.

[0049] 6, the support portion 26 and the support portion 31 are connected to each other in each configuration of the support portion 20. Specifically, the end of the second side Y2 of the plate-like body 27 is connected to the end of the first side X1 of the plate-like body 33. The end of the second side Y2 of the plate-like body 28 is connected to the end of the first side X1 of the plate-like body 32. The support body 20A of the second modified example configured as above can also achieve the same effects as the support body 20 of this embodiment.

In this disclosure, the vertical wall members are supported by support parts arranged along a single continuous vertical wall arrangement reference line that is linear or L-shaped in plan view. Since only support parts that support the vertical wall members and are arranged along the single continuous vertical wall arrangement reference line are arranged on the bottom, it is easy to arrange other members other than the support parts on the bottom.

[0053] (2) A second aspect of the present disclosure may be the support according to (1), in which the support portion includes a plurality of support portions spaced apart from one another along the vertical wall arrangement reference line. In this disclosure, the amount of material required to construct multiple support parts can be reduced, and the cost required to manufacture multiple support parts can be suppressed, compared to when the support parts are arranged continuously and without gaps along the vertical wall placement reference line.

[0054] (3) Aspect 3 of the present disclosure may be a support as described in (1) or (2), in which the support portion comprises a pair of plate-like bodies, and the pair of plate-like bodies support the vertical wall member in a sandwiched state between the pair of plate-like bodies. In this disclosure, the pair of plate-like bodies can reliably support the vertical wall member in a state where the vertical wall member is sandwiched between the pair of plate-like bodies.

[0055] (4) A fourth aspect of the present disclosure may be a support according to any one of (1) to (3), in which the vertical wall member is supported by the support part with one side of the thickness direction filled with concrete and the other side of the thickness direction filled with earth and stones, and the entire support part and the entire vertical wall member are buried under the floor. In this disclosure, the support is buried under the floor between concrete and earth and stone. Therefore, the support can be buried without being removed or dismantled, and the number of steps required to construct the support can be reduced.

[0056] (5) Aspect 5 of the present disclosure is a substructure of a building, comprising a support body described in any one of (1) to (4), the vertical wall member, and an L-shaped channel-shaped precast concrete body, wherein the precast concrete body is positioned such that the first surface of the L-shape forms a bottom surface along a horizontal plane, and the bottom of the support body is positioned in a stacked state below the first surface of the precast concrete body.

[0057] In this disclosure, the vertical wall member can be supported by a support portion, and the position of the support can be maintained by the precast concrete molded body by placing the first surface of the precast concrete molded body on the bottom of the support.

[0058] (6) Aspect 6 of the present disclosure may be a substructure of a building described in (5), in which the precast concrete body has a vertical wall portion along a vertical plane as a second surface forming an L-shape, and the vertical wall portion has a portion located at a height above floor level. In this disclosure, the upper end of the vertical wall portion can be made to protrude above the floor level.
