Summary of the Invention

Problems to be Solved by the Invention

[0004] Placing other members on the substrate of the support and holding the position of the support have been considered. However, since the support of Patent Document 1 includes two sets of combinations of leg pieces and inner claw pieces along the substrate, there is a risk that the two sets of leg pieces and inner claw pieces may hinder when arranging other members on the substrate.

[0005] The present disclosure has been made in view of such problems, and an object thereof is to provide a support that facilitates arranging other members on the bottom, and a substructure of a building including this support.

Means for Solving the Problems

[0006] This disclosure provides a support body comprising a plate-shaped base that is installed on the ground, and a support portion that is erected from the base to support vertical wall members and is arranged along a single continuous vertical wall arrangement reference line that is linear or L-shaped in plan view. Furthermore, this disclosure provides a substructure for a building comprising a support, the vertical wall member, and an L-shaped channel-shaped precast concrete molded body, wherein the precast concrete molded body is positioned such that its first L-shaped surface is the bottom surface along the horizontal plane, and the bottom portion of the support is positioned stacked below the first surface of the precast concrete molded body. [Effects of the Invention]

[0007] The support and substructure of the building of this disclosure make it easier to place other members on the bottom. [Brief explanation of the drawing]

[Figure 2] This is a cross-sectional view along the cutting line A1-A1 in Figure 1. [Figure 3] This is a plan view of the other support structures in the same building. [Figure 4] This is a perspective view of the precast concrete molded body in the building. [Figure 5] This is a plan view of the first modified example of the support. [Figure 6] This is a plan view of a second modified example of the support. [Modes for carrying out the invention]

[0009] Hereinafter, an embodiment of the support and substructure of a building relating to this disclosure will be described with reference to Figures 1 to 6. As shown in Figures 1 and 2, the supports 10 and 20 of this embodiment are used in the substructure (hereinafter simply referred to as the substructure) 2 of the building 1. That is, in this embodiment, the substructure 2 comprises multiple types of supports 10 and 20. The substructure 2 comprises support members 10, 20, precast concrete molded 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 corresponding to the shape of the substructure 2. For example, the substructure 2 has a rectangular outer edge when viewed from above. Similarly, the depression G2 has a rectangular outer edge when viewed from above. In this example, a base mortar (mortar) 100 is placed on the bottom surface (ground) G3 of the depression G2. Note that the building 1 does not necessarily need to have a base mortar 100.

[0011] As shown in Figures 1 and 2, the support body 10 comprises a bottom portion 11 and a support portion 16. The bottom portion 11 is formed in a plate shape from a steel plate or the like. In this example, when viewed along the thickness direction of the bottom portion 11, the bottom portion 11 has a rectangular shape. Here, A being aligned with B means that the angle between A and B is 30 degrees or less. It is more preferable that this angle is 15 degrees or less. The bottom portion 11 is installed on the bottom surface G3 via the bedding mortar 100. That is, the bottom portion 11 is positioned so that its thickness direction is aligned with the vertical direction Z.

[0012] Here, in the plan view shown in Figure 1, the direction along the first side 11a of the base 11 is defined as the first direction X. In the plan view, the direction along the second side 11b of the base 11 is defined as the second direction Y. The second direction Y is perpendicular to the first direction X. The vertical direction Z is perpendicular to the first direction X and the second direction Y, respectively.

[0013] In plan view, among the first direction X, the direction 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, among the first direction X, the direction 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 plan view, one of the second direction Y is defined as the first side Y1 (hereinafter, simply referred to as the first side Y1). The other of the second direction Y is defined as the second side Y2 (hereinafter, simply referred to as the second side Y2). Hereinafter, the directions with respect to the support 20, the precast concrete molded bodies 40, 45, the vertical wall members 50, etc. are defined by the first direction X, the second direction Y, etc. in the support 10.

[0014] Note that the shape of the bottom 11 when viewed along the thickness direction of the bottom 11 is not limited to a rectangular shape, and may be a triangular shape, a hexagonal shape, etc.

[0015] As shown in FIGS. 1 and 2, the support portion 16 stands upright from the bottom 11 upward in the vertical direction Z (hereinafter, referred to as upward). 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 in a plate shape with a steel plate or the like, and are arranged such that the thickness direction of the plate-like bodies 17, 18 is along 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 exhibit a rectangular shape.

[0016] The plate-like bodies 17, 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 upright upward from the end of the second side X2 of the bottom 11. The plate-like body 17 stands upright upward from the middle portion of the first direction X of the bottom 11. As shown in FIG. 1, the positions of the ends of the first side Y1 of the bottom 11, the positions of the ends of the first side Y1 of the plate-like bodies 17, and the positions of the ends of the first side Y1 of the plate-like body 18 coincide in the second direction Y. The positions of the ends of the second side Y2 of the bottom 11, the positions of the ends of the second side Y2 of the plate-like bodies 17, and the positions of the ends of the second side Y2 of the plate-like body 18 coincide in the second direction Y.

[0017] The plate-like bodies 17 and 18 are connected to the bottom 11 by welding or the like while being separated from each other so as to sandwich the vertical wall arrangement reference line L. Next, the vertical wall member 50 will be described. As shown in FIGS. 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 and 18 provided in the support portion 16 of the support body 10 support the vertical wall member 50 in a state of sandwiching it in the first direction X with the plate-like bodies 17 and 18. The vertical wall member 50 protrudes upward from above the upper ends of the plate-like bodies 17 and 18.

[0018] As shown in FIG. 1, here, in a plan view, a reference line L1 is defined that is orthogonal to the direction (the 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 body 17 and the plate-like body 18. [[ID=十六]]In the present embodiment, the support portion 16 is arranged linearly in a plan view. When it is said here that the support portion 16 is arranged linearly in a plan view, it 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 constitutes 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, when A is along B, it means that the angle formed by A and B is 30 degrees or less. This formed angle is more preferably 15 degrees or less.

[0019] As shown in FIGS. 1 and 3, the support body 20 includes a bottom 21 and support portions 26 and 31. As shown in Figure 3, the bottom portion 21 is constructed in the same way 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 parts 26 and 31 are erected upward from the bottom part 21. The support parts 26 and 31 support the vertical wall members 50. The support body 20 includes support parts 26 and 31, which are a plurality of support parts spaced apart from each other along the vertical wall arrangement reference line L. Specifically, the support portion 26 comprises a pair of plate-like bodies 27 and 28. The plate-like bodies 27 and 28 are each formed in the shape of a plate from steel or the like, and are arranged so that the thickness direction of the plate-like bodies 27 and 28 is aligned with the first direction X. In this example, when viewed along the thickness direction of the plate-like bodies 27 and 28, the plate-like bodies 27 and 28 each exhibit 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. Plate-like body 27 is positioned further to the first side X1 than plate-like body 28. In this example, the plate-like bodies 27 and 28 are erected upward from the middle of the first direction X at the bottom 21. The positions of the first side Y1 end of the bottom portion 21, the first side Y1 end of the plate-like body 27, and the first side Y1 end of the plate-like body 28 coincide in the second direction Y. The second side Y2 end of the plate-like body 27 and the second side Y2 end of the plate-like body 28 are located in the middle of the second direction Y of the bottom portion 21.

[0022] The support portion 31 comprises a pair of plate-like bodies 32 and 33. Each of the plate-like bodies 32 and 33 is formed in the shape of a plate from a steel plate or the like, and is arranged so that the thickness direction of the plate-like bodies 32 and 33 is aligned with the second direction Y. In this example, when viewed along the thickness direction of the plate-like bodies 32 and 33, each of the plate-like bodies 32 and 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. Plate-like body 32 is positioned on the first side Y1 than plate-like body 33. In this example, the plate-like bodies 32 and 33 are erected upward from the middle of the second direction Y at the bottom 21. The positions of the ends of the second side X2 of the base 21, the second side X2 of the plate-like body 32, and the second side X2 of 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 first side X1 of the plate-like body 33 are located in the middle of the first direction X of the base 21. The first side X1 end of plate-like bodies 32 and 33 is positioned on the second side X2 and second side Y2, rather than on the second side Y2 end of plate-like bodies 27 and 28. In other words, plate-like bodies 32 and 33 are separated.

[0024] The plate-like bodies 27, 28, 32, and 33 are connected to the bottom portion 21 by welding or other means. The plate-like bodies 27 and 28 provided on the support portion 26 of the support body 20 support the vertical wall member 50 by sandwiching it in a first direction X with the plate-like bodies 27 and 28. The plate-like bodies 32 and 33 provided on the support portion 31 of the support body 20 support the vertical wall member 50 by sandwiching it in a second direction Y with the plate-like bodies 32 and 33.

[0025] Here, in a plan view, a reference line L3 is defined that is perpendicular to the direction in which the plate-like bodies 27 and 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 and 28. In a plan view, a reference line L4 is defined that is perpendicular to the direction in which the plate-like bodies 32 and 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 sections 26 and 31 are arranged in an L-shape in a plan view. Here, the arrangement of the support sections 26 and 31 in an L-shape in a plan view means that the reference lines L3 and L4 corresponding to the support sections 26 and 31 are L-shaped in a plan view. Thus, reference lines L3 and L4 constitute a single, continuous vertical wall arrangement reference line L that is L-shaped in a plan view. The angle θ1 between reference line L3 and reference line L4 is not limited as long as it is greater than 0° and less than 180°.

[0026] As shown in Figure 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] As shown in Figures 1 and 2, the precast concrete molded bodies 40 and 45 are L-shaped channels. That is, when the precast concrete molded body 40 is viewed along its longitudinal direction, it has an L-shaped trench. The same applies to the precast concrete molded body 45. The precast concrete molded body 40 comprises a bottom wall portion (bottom) 41 and a vertical wall portion 42. The bottom wall portion 41 and the vertical wall portion 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 positioned such that its thickness direction is aligned with the vertical direction Z. As shown in Figure 2, the lower surface (first surface) 41a of the bottom wall portion 41 is aligned with the horizontal plane. The lower surface 41a becomes the bottom surface of the precast concrete molded body 40. The vertical wall section 42 is erected upward from the first side X1 end of the bottom wall section 41. The surface of the vertical wall section 42 facing the first side X1 is the second surface 42a, which forms an L shape. The second surface 42a is aligned with the vertical plane. For example, the length of the vertical wall section 42 in the vertical direction Z is 2m.

[0029] The precast concrete molded body 40 is positioned so that its L-shaped lower surface 41a is aligned with the horizontal plane. The bottom portion 11 of the support 10 is positioned stacked below the lower surface 41a of the precast concrete molded body 40. The bottom wall portion 41 and 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 the corner of the substructure 2. As shown in Figures 1 and 4, the precast concrete molded body 45 comprises 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 positioned such that its thickness direction is aligned with the vertical direction Z. A notch 46a is formed in the 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 section 47 is erected upward from the first side X1 end of the bottom wall section 46. The second vertical wall section 48 is erected upward from the second side Y2 end of the bottom wall section 46. The first side X1 end of the second vertical wall section 48 is connected to the first vertical wall section 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 section 47, the upper end of the second vertical wall section 48, and the upper end of the vertical wall section 42 of the precast concrete molded body 40 are located at the same height. As shown in Figure 1, the upper end of the vertical wall portion 42 is positioned above the upper end of the vertical wall member 50.

[0033] As shown in Figure 1, the support body 20 and the precast concrete molded body 45 are positioned at the corner of the substructure 2 in a plan view. At this time, the bottom portion 21 of the support body 20 is positioned stacked below the bottom wall portion 46 of the precast concrete molded body 45. The precast concrete molded body 40 is positioned alongside the precast concrete molded body 45 on the first side Y1 and the second side X2, respectively. The vertical wall member 50, supported by the support portions 26 and 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 relative to the notch 46a.

[0034] In this embodiment, the substructure 2 comprises a plurality of support members 10. A portion of the plurality of support members 10 (hereinafter also referred to as support member 10A) each supports the ends of two vertical wall members 50 arranged in the second direction Y. That is, the two vertical wall members 50 supported by support member 10A are both aligned in a straight line when viewed from above and are connected to each other in the second direction Y. The bottom portion 11 of the support 10A is positioned stacked below the bottom wall portions 41 of two precast concrete molded bodies 40 that are arranged in a second direction Y. As shown in Figure 2, it is preferable that the plate-like body 17 of the support 10A is in contact with the bottom wall portion 41 of the precast concrete molded body 40 from the second side X2 beyond the bottom wall portion 41.

[0035] As shown in Figure 1, the remaining parts of the multiple support members 10 (hereinafter also referred to as support members 10B) each support the ends of two vertical wall members 50 arranged in the first direction X. That is, the two vertical wall members 50 supported by the support members 10B are both aligned 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 10B is positioned stacked below the bottom wall portions 41 of two precast concrete molded bodies 40 that are arranged in a first direction X.

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

[0037] As shown in Figure 2, concrete 105 is filled into the first side X1 of the vertical wall member 50. The concrete 105 is filled between the vertical wall member 50 and the vertical wall portion 42 of the precast concrete molded body 40, and is filled 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 soil and stone 107. Here, soil and stone 107 means soil (which may be at least one of clay, humus, and sand), stone (which may be crushed stone), or a mixture thereof. The soil and stone 107 may be excavated soil (returned soil) or topsoil. The particle size of the soil is not limited.

[0038] The vertical wall member 50 is supported by the support parts 16, 26, and 31 of the support bodies 10 and 20, sandwiched in the first direction X by the concrete 105 and the earth and stone 107. The entirety of the support parts 16, 26, and 31 and the entirety of the vertical wall member 50 are embedded below (under the floor) of the floor 109. The upper surface of the floor 109 is the floor level 109a. The floor level 109a is positioned 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 of floor level 109a or higher. The vertical wall portion 42 forms part of the parapet wall 111 in the building 1. In addition, insulation material may be placed below floor 109.

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

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

[0042] The support body 20 includes support parts 26 and 31 that are spaced apart from each other along the vertical wall alignment reference line L. This reduces the amount of material required to construct the support parts 26 and 31 and suppresses the cost required to manufacture the support parts 26 and 31, compared to the case where the support parts are arranged continuously without gaps along the vertical wall alignment reference line. The plate-like bodies 17 and 18 support the vertical wall member 50 by sandwiching it in the first direction X. Therefore, the plate-like bodies 17 and 18 can reliably support the vertical wall member 50 by sandwiching it between them.

[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 soil and stone 107, and the entire support section 16 and the entire vertical wall member 50 are buried below the floor 109. This allows the support structure 10 to be buried without being removed or dismantled, and reduces the man-hours required when constructing the support structure 10. Furthermore, in the substructure 2 of this embodiment, the vertical wall member 50 can be supported by the support portion 16. By placing the lower surface 41a of the precast concrete molded body 40 on the bottom portion 11 of the support body 10, the position of the support body 10 can be maintained by the precast concrete molded body 40.

[0044] The precast concrete molded body 40 is equipped with vertical wall sections 42, and the vertical wall sections 42 have portions located at a height of 109a or higher than the floor level. Therefore, the upper end of the vertical wall section 42 can be made to protrude above the floor level 109a. The vertical wall portion 42 forms part of the parapet wall 111 in the building 1. Therefore, the vertical wall portion 42 can constitute part of the parapet wall 111 in the building 1.

[0045] The supports 10 and 20 of this embodiment can be modified in various ways, as described below. The support 10A of the first modified example shown in Figure 5 is provided with support parts 16A and 16B in place of support part 16 in each configuration of the support 10. That is, the support 10A is provided with support parts 16A and 16B, which are a plurality of support parts that are spaced apart from each other along the vertical wall alignment reference line L. Support section 16A comprises plate-like bodies 17A and 18A. The plate-like bodies 17A and 18A are erected on the bottom 11 at a distance from each other, straddling the vertical wall alignment reference line L, similar to the plate-like bodies 17 and 18. Support section 16B comprises plate-like bodies 17B and 18B. The plate-like bodies 17B and 18B are erected on the bottom 11 at a distance from each other, straddling the vertical wall alignment reference line L, similar to the plate-like bodies 17 and 18. Plate-like bodies 17A and 17B are arranged with a gap between them in the second direction Y. Plate-like bodies 18A and 18B are arranged with a gap between them in the second direction Y.

[0046] In other words, the support parts 16A and 16B are constructed by dividing the support part 16 into two parts in the second direction Y.

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

[0048] The support 10A of the first modified example, configured as described 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 sections in the second direction Y.

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

[0050] Although one embodiment and its modifications have been described in detail above with reference to the drawings, the specific configuration is not limited to this embodiment and its modifications, and may include changes, combinations, deletions, etc., of the configuration that do not depart from the gist of this disclosure. For example, in the above embodiment and its modified form, the support portion may not include a pair of plate-like bodies, but rather have plate-like bodies on only one of the two sides of the vertical wall member 50.
