[Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2019-138053 A Summary of the Invention [Problem to be solved by the invention]

[0004] In conventional building design methods such as that described in Patent Document 1, the layout and dimensions of columns, beams, and walls must be set from scratch for each variation of the building, making the design process complicated.

[0005] An object of the present invention is to provide a method for designing a building that can be designed easily, and a building itself. [Means for solving the problem]

[0006] The method for designing a building of the present invention includes a structural unit definition process for defining an outer frame consisting of a plurality of columns arranged so that the axis center distance between them is a multiple of a design standard dimension and a plurality of beams connecting the plurality of columns as one structural unit; a structural unit arrangement process for arranging a plurality of the structural units at any horizontally consecutive positions so that they share each other's beams; a wall setting process for setting walls along the beams in an inner area of ​​the consecutive structural units to a length that is a multiple of the standard dimension and defining a closed section surrounded by the walls; a wall section division process for dividing the walls into a plurality of wall sections whose dimensions in the beam extension direction in which the beams extend are the standard dimensions; a wall allocation process for allocating a plurality of walls whose dimensions in the beam extension direction are the same as one or more of the wall sections to the wall sections to constitute the walls; and a slab setting process for setting a continuous slab across a plurality of the structural units.

This eliminates the need to set the arrangement and dimensions of the columns, beams and walls from scratch for each variation of the building, making it possible to design buildings easily.

[0008] In the building design method of the present invention, in the wall allocation process, a plurality of walls having the same dimensions in the beam extension direction as one or more of the wall sections but different configurations may be assigned to any one of the wall sections.

[0009] According to the present invention, a plurality of wall bodies having the same dimensions but different configurations as one or more wall sections are assigned to any one of said wall sections, so that a plurality of different wall bodies can be easily arranged according to variations in the building.

[0010] In the method for designing a building of the present invention, at least one of the walls may be a seismic wall fixed to a foundation of the building.

[0011] According to the present invention, the wall body is a seismic wall fixed to the foundation of a building, so that the strength of the building can be improved.

[0012] The building of the present invention comprises an outer frame consisting of a number of columns arranged so that the distance between their axis centers is a multiple of a standard dimension and a number of beams connecting the plurality of columns, which are arranged in succession horizontally so as to share each other's beams, a wall section arranged along the beams in the inner area of ​​the consecutive structural units to define a closed compartment, and a slab continuing across a number of the structural units, the wall section being divided into a number of wall sections whose dimension in the beam extension direction in which the beams extend is the standard dimension, and a number of wall bodies whose dimension in the beam extension direction is the same as one or more of the wall sections are assigned to the wall section to constitute the wall section.

[0015] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the following description, directions are indicated based on the view of the building 100 as shown in Fig. 1. In the second and subsequent embodiments, the same components and components having similar functions as those in the first embodiment are denoted by the same reference numerals as those in the first embodiment, and descriptions thereof will be omitted or simplified.

[0016] [First embodiment] In Figures 1 to 3, the building 100 has a frame structure in which an outer frame consisting of a number of columns 11 arranged so that the distance between their axis centers is a multiple of the design standard dimension SD and a number of beams 12 connecting the plurality of columns 11 is treated as one structural unit 10, and the plurality of structural units 10 are arranged at any position horizontally consecutive to each other. The building 100 includes frame units 10A and 10B as the frame unit 10, a wall section 20, and a slab 30.

[0017] The frame units 10A and 10B have an out-frame structure arranged outside the wall portion 20. The frame units 10A and 10B are each square in plan view, with columns 11 at the four corners connected by beams 12. In this embodiment, the frame units 10A and 10B are disposed consecutively in the left-right direction so as to share the beam 12 in the front-rear direction, and the frame unit 10B is disposed shifted backward with respect to the frame unit 10A. In order for the frame units 10A and 10B to share each other's beam 12, one pillar 11 of the frame unit 10B is disposed between two pillars 11 of the frame unit 10A. For this reason, the shared beam 12 is divided into a beam 12A, and the beam 12A connects the two pillars 11 of the frame unit 10A and the one pillar 11 of the frame unit 10B disposed between the pillars 11.

[0018] The pillar 11 is made of a rectangular steel pipe having a substantially square cross section, and extends from the foundation 40 to the roof slab 30A of the second floor. The beam 12 is configured by welding flat steel to the flanges of the H-shaped steel so as to cover the space between the flanges (see Figs. 4(B) and (C)).

[0019] The wall section 20 is disposed along the beam 12 inside the continuous frame units 10A, 10B, and defines a closed section CS surrounded by the wall section 20. The wall section 20 includes a seismic wall 21, an ALC (Autoclaved Lightweight Aerated Concrete) panel 22, a sash window 23, a door 24, and a beam insertion panel 25. The wall section 20 includes an exterior wall section 20A that separates the inside and outside of the building 100, and an interior wall section 20B that separates the closed sections CS of the frame units 10A and 10B. In the present embodiment, the exterior wall section 20A is connected to the interior wall section 20B by a beam-passing panel 25, and the interior wall section 20B is composed of a plurality of ALC panels 22 arranged below and along the beam 12A.

[0020] The earthquake-resistant wall 21, the ALC panel 22, the sash window 23, the door 24, and the beam-passing panel 25 are wall bodies that make up the wall section 20, and each has a different structure and function. Also, when the wall section 20 is divided into a plurality of wall sections, each of which has a standard dimension SD in the direction in which the beams 12 extend (hereinafter referred to as the beam extension direction), the earthquake-resistant wall 21, the ALC panel 22, the sash window 23, the door 24, and the beam-passing panel 25 has the same dimension in the beam extension direction as one wall section.

[0021] 4(A) to 4(C), the earthquake-resistant wall 21 is made of a steel material having a generally H-shaped cross section and including a web 211 and a flange 212. In the present embodiment, two earthquake-resistant walls 21 are arranged side by side, and the flanges 212 are joined by bolts with a generally L-shaped bracket 213 sandwiched therebetween. The flanges 212 protrude outward from both ends of one and the other surfaces of the web 211, with the amount of protrusion being greater on the other surface side than on the one surface side. A substantially L-shaped bracket 214 is provided on the upper surface of the flange 212, protruding upward from the upper surface and extending toward one surface side of the web 211. Brackets 213 and 214 are bolted to bracket 121 provided on the upper surface of beam 12 , thereby joining the upper end of earthquake-resistant wall 21 to beam 12 .

[0022] As shown in FIG. 5(A), the earthquake-resistant wall 21 is installed continuously from the first floor to the second floor of the building 100, and extends from the foundation 40 of the building 100 through the floor slab 30B of the first floor and the floor slab 30B of the second floor to the roof slab 30A of the second floor. The earthquake-resistant wall 21 is provided with a stud dowel 215, and the peripheral portion of the stud dowel 215 in the earthquake-resistant wall 21 is embedded in the slab 30 and the foundation 40. The upper end of the earthquake-resistant wall 21 is embedded in the roof slab 30A of the second floor as shown in FIG. 5(B). The portion of the earthquake-resistant wall 21 embedded in the floor slab 30B of the second floor is joined to the beam 12 via brackets 121 and 216 that are bolted to each other as shown in FIG. 5(C).

[0023] 6(A) and (B), the lower end of the earthquake-resistant wall 21 is supported by a base plate 44 that is fixed to a foundation beam 41 with anchor bolts 43 by sandwiching non-shrink mortar 42 between them, and is wrapped with concrete poured from the foundation beam 41 to the floor slab 30B of the first floor. A notch 217 is provided at the lower end of a web 211 of the earthquake-resistant wall 21 to prevent interference with the anchor bolts 43, and a reinforcing rib 218 is provided. A backing metal 441 that protrudes upward from the base plate 44 is provided on the upper surface of the base plate 44, and the flange 212 of the earthquake-resistant wall 21 is positioned and welded to the backing metal 441.

[0024] The ALC panels 22 , sash windows 23 , and doors 24 are fixed at their upper and lower ends to embedded anchors embedded in the slab 30 . The sash window 23 includes a fixed window 23A fixed to the slab 30 and a sliding window 23B. The door 24 may be, for example, a hinged door, a sliding door, a folding door, or the like, but in this embodiment, it is configured as a sliding door.

[0025] As shown in Fig. 7(A), the beam-passing panel 25 is configured such that a space surrounded by a hot-dip galvanized steel panel 251 is filled with rock wool 252. The lower end of the beam-passing panel 25 is fixed to the slab 30 via a mounting bracket 253 in a groove 31 formed in the slab 30, and the groove 31 is filled with concrete or mortar. The upper end of the beam-passing panel 25 is fixed to an oar anchor 32 provided on the slab 30 via a mounting bracket 254. Also, as shown in Figure 7 (B), a cutout 255 for passing the beam 12 is provided at the upper end of the beam-passage panel 25, and the gap between the upper end of the beam-passage panel 25 including the cutout 255 and the beam 12 is sealed with a sealing member 256.

[0026] The slab 30 is provided continuously across the frame units 10A, 10B, and is shaped to protrude outward by the same amount from each side of the frame units 10A, 10B in a plan view. The slab 30 has a roof slab 30A and a floor slab 30B, and part of the floor slab 30B on the second floor is used as a balcony 50, on which a fence-like handrail 51 is installed. Note that the handrail 51 is simplified in FIG. 1, and only its outer frame is shown.

[0027] The design method for the building 100 will be described below with reference to the flowchart in FIG. 8 and to FIGS. First, in step ST1 of FIG. 8, an outer frame in which a plurality of columns 11 arranged so that the axis center distance is a multiple of the reference dimension SD is connected by beams 12 is defined as one frame unit 10 (step ST1, frame unit definition process). At this time, the planar shape of the frame unit 10, the number, thickness, length, and axis distance of the columns 11 in the frame unit 10, and the number, thickness, and length of the beams 12 are arbitrarily set. In the case of this embodiment, for example, the reference dimension SD is set to 600 mm, and the axis center distance of the columns 11 is set to 5400 mm, which is 9 times the reference dimension SD, and four columns 11 are arranged at the four corners of a square so that the frame units 10A and 10B are square in plan view. The reference dimension SD may be set in the process of defining the frame unit 10, or may be set in advance before defining the frame unit 10.

[0028] Next, as shown in Fig. 9, the multiple frame units 10A, 10B are arranged at any horizontally consecutive positions so as to share each other's beams 12 (step ST2, frame unit arrangement step). In Fig. 9, the frame units 10A, 10B are arranged so as to share one of the multiple beams 12A obtained by dividing the beam 12.

[0029] Next, as shown in Fig. 10, in the region inside the continuous frame units 10A, 10B, the wall 20 is set along the beam 12 to a length that is a multiple of the reference dimension SD, and a closed section CS surrounded by the wall 20 is defined (step ST3, wall setting process). At this point, it does not matter what material the wall 20 will be made of, as long as the arrangement of the wall 20 is determined. In Fig. 10, the wall 20 is arranged at a position 0.5 SD away from the beam 12, which is 0.5 times the reference dimension SD, in a plan view.

[0030] Next, the wall portion 20 is divided into a plurality of wall sections whose dimensions in the beam extension direction are the reference dimensions SD (step ST4, wall portion dividing step).

[0031] Next, a plurality of walls, each having the same dimensions in the beam extension direction as one or more wall sections but different configurations, are assigned to any wall section to form wall section 20 (step ST5, wall assignment process). In Fig. 10, earthquake-resistant wall 21, ALC panel 22, sash window 23, door 24, and beam-passing panel 25 are used as walls, each of which is configured to have the same dimensions as one wall section and is arranged as shown in Fig. 10.

[0032] Thereafter, a continuous slab 30 is set across the plurality of frame units 10A, 10B (step ST6, slab setting step).

[0033] According to the above embodiment, structural units 10 including a plurality of columns 11 whose axial center distance is a multiple of the standard dimension SD and beams 12 connecting the columns 11 are arranged at any horizontally consecutive positions, and a plurality of wall sections obtained by dividing the wall section 20 by the standard dimension SD are assigned to a plurality of wall bodies having the same dimensions as the wall sections. This eliminates the need to set the arrangement and dimensions of the columns 11, beams 12, and wall sections 20 from scratch for each variation of the building 100, and makes it possible to easily design the building 100.

[0034] In addition, since a plurality of wall bodies having the same dimensions as a wall section but different configurations can be assigned to any wall section, a plurality of different wall bodies can be easily arranged for each variation of the building 100.

[0035] Furthermore, since the earthquake-resistant wall 21 fixed to the foundation 40 of the building 100 serves as a wall body, the bearing strength of the building 100 can be improved.

[0036] [Second embodiment] As shown in FIG. 11, in this embodiment, the number of frame units 10 is different from that in the first embodiment, and three frame units 10A, 10B, and 10C are provided.

[0037] The frame units 10A, 10B, and 10C are successively arranged in the left-right direction so as to share the beam 12 in the front-rear direction, and are arranged with a shift such that the frame unit 10B is shifted rearward from the frame unit 10A, and the frame unit 10C is shifted rearward from the frame unit 10B. The frame unit 10B shares the beam 12A with the frame units 10A and 10C, and the two columns 11 of the frame unit 10A and the two columns 11 of the frame unit 10C are connected by the beam 12A via one column 11 of the frame unit 10C that is arranged between the respective columns 11.

[0038] The inner wall portion 20B of the wall portion 20 is provided in two places that separate the closed compartments CS of the frame units 10A and 10C from the closed compartment CS of the frame unit 10B. The arrangement of the earthquake-resistant walls 21, ALC panels 22, sash windows 23, doors 24, and beam-passing panels 25 in the wall portion 20 is the same as in the first embodiment, so they are denoted by the same reference numerals as in the first embodiment and the description thereof will be omitted.

[0039] [Third embodiment] As shown in FIG. 12, this embodiment differs from the first embodiment in the number and arrangement of frame units 10A, 10B, and 10C, and the arrangement of earthquake-resistant walls 21, ALC panels 22, sash windows 23, doors 24, and beam insertion panels 25.

[0040] The structural units 10A, 10B, and 10C are arranged consecutively in the left-right direction so as to share the fore-aft beam 12, with the structural unit 10B being shifted rearward relative to the structural unit 10A and the structural unit 10C being shifted forward relative to the structural unit 10B.

[0041] The earthquake-resistant wall 21, ALC panel 22, sash window 23, door 24, and beam insertion panel 25 have the same configuration as in the first embodiment, only their arrangement is different, so they are given the same reference numerals as in the first embodiment and their explanations are omitted.

[0042] [Fourth embodiment] As shown in FIG. 13, this embodiment differs from the first embodiment in the number and arrangement of frame units 10A, 10B, and 10C, and the arrangement of earthquake-resistant walls 21, ALC panels 22, sash windows 23, doors 24, and beam insertion panels 25.

[0043] The frame units 10A and 10B are successively arranged in the front-rear direction so as to share the beam 12 in the left-right direction, and the frame unit 10B is arranged shifted to the right with respect to the frame unit 10A. On the other hand, the frame units 10B and 10C are successively arranged in the left-right direction so as to share the beam 12 in the front-rear direction, and the frame unit 10C is arranged shifted backward with respect to the frame unit 10B.

[0044] The earthquake-resistant wall 21, ALC panel 22, sash window 23, door 24, and beam insertion panel 25 have the same configuration as in the first embodiment, only their arrangement is different, so they are given the same reference numerals as in the first embodiment and their explanations are omitted.

[0045] [Variations] The present invention is not limited to the above-described embodiment, and includes modifications and improvements within the scope of the present invention that can achieve the object of the present invention. For example, the number of frame units 10 arranged consecutively in the horizontal direction may be four or more. The planar shape of the frame unit 10 may be a quadrilateral such as a square or a rectangle, a rhombus, a parallelogram, or the like, a triangle, or a polygon having 5 or more sides. The pillar 11 may be made of steel of any shape, such as a square steel pipe, a circular steel pipe, or an H-shaped steel pipe. For the beam 12, an H-shaped steel may be used as it is, or a steel material other than an H-shaped steel may be used.

[0046] The wall section 20 may be composed of one or more of the earthquake-resistant walls 21, the ALC panels 22, the sash windows 23, the doors 24, and the beam-passing panels 25, or may include walls other than the earthquake-resistant walls 21, the ALC panels 22, the sash windows 23, the doors 24, and the beam-passing panels 25. For example, the wall section 20 may be composed of the earthquake-resistant walls 21, the doors 24, and the beam-passing panels 25 assigned to the wall section. The outer wall portion 20A may be disposed at a position spaced apart from the beam 12 by the standard dimension SD in a plan view, or may be disposed at a position spaced apart by a multiple of the standard dimension SD. In place of the beam-passing panel 25, the exterior wall portion 20A may use a seismic wall 21, an ALC panel 22, a sash window 23, or other wall bodies of a height that does not interfere with the beams 12, and the gap between such a wall body and the roof slab 30A may be sealed with a sealing member 256. For the inner wall portion 20B, either one of the earthquake-resistant wall 21 and the sash window 23 or a wall other than these may be used in place of the ALC panel 22 or in combination with the ALC panel 22. The dimensions of the wall sections or wall bodies in the beam extension direction when viewed in a plan view may be the same as the standard dimension SD, or may be a multiple of the standard dimension SD that is twice or more, or may be 0.5 or 1.5 times the standard dimension SD, etc. The walls may be configured to continue through the slab 30 for multiple floors.

[0047] The earthquake-resistant wall 21 may be made of H-shaped steel or U-shaped channel steel or any other shape of iron, and the web 211 may be made thicker or constructed by stacking flat steel bars, so that it does not have to be provided with flanges 212, or the flanges 212 may be provided only on one side or the other side of the web 211, or no flanges 212 may be provided and brackets 213, 214 may be provided at both ends of the web 211. The number of the shear walls 21 arranged side by side and the joint structure between them are not particularly limited, and the shear walls 21 do not have to be arranged in a row of two, or three or more shear walls 21 may be arranged in a row, the shear walls 21 may be joined by welding instead of bolt joints, the shear walls 21 may be joined only at the portions embedded in the slab 30 or the foundation 40, or only at the portions not embedded in the slab 30 or the foundation 40, or both at the portions embedded in the slab 30 or the foundation 40 and not embedded in the slab 30 or the foundation 40. When joining the portions not embedded in the slab 30 or the foundation 40, bolt holes are provided at equal pitches PT in the flanges 212 of the shear walls 21, and the shear walls 21 may be joined by bolts 219 inserted through all of these bolt holes, or the shear walls 21 may be joined by bolts 219 selectively inserted through only some of the bolt holes. In this manner, the rigidity of the earthquake-resistant walls 21 can be adjusted by changing the number of earthquake-resistant walls 21 arranged side by side and the joint structure between them. The number of earthquake-resistant walls 21 assigned to the wall sections of the frame unit 10 is not particularly limited and can be set arbitrarily. By changing the number of earthquake-resistant walls 21 assigned, it is possible to easily eliminate bias in the rigidity on the plane of the building 100 without significantly changing the appearance of the building 100. The earthquake-resistant wall 21 may be fixed to the foundation 40 of the building 100 or to the slab 30 . The earthquake-resistant walls 21 do not have to be continuous vertically from the first floor to the top floor of the building 100; in this case, the arrangement of the earthquake-resistant walls 21 may be different between the first and second floors, or the upper end of the earthquake-resistant wall 21 on the first floor may be embedded in the roof slab 30A of the first floor (floor slab 30B of the second floor), or the upper end of the earthquake-resistant wall 21 on the second floor may be embedded in the roof slab 30A of the second floor and the lower end may be embedded in the floor slab 30B of the second floor (roof slab 30A of the first floor). The material, shape, and number of earthquake-resistant walls to be installed are not particularly limited. For example, the earthquake-resistant walls may be made of reinforced concrete or wood, or the reinforced concrete earthquake-resistant walls may be fabricated (precast) in a factory, or the reinforced concrete earthquake-resistant walls may be prestressed on-site, or the reinforced concrete or wooden earthquake-resistant walls may have the same shape as earthquake-resistant wall 21, or may have a different shape from earthquake-resistant wall 21.

[0048] Any one or more of the walls of the ALC panel 22, the sash window 23, the door 24, and the beam insertion panel 25 may be fixed to the foundation 40. The beam-passing panel 25 may be a wall body having a cutout for passing the beam 12 through, the earthquake-resistant wall 21, the ALC panel 22, the sash window 23, or other wall body.

[0049] The slab 30 may have a shape that protrudes outwardly from each side of the frame units 10A, 10B by different dimensions in a plan view, or may have a shape that does not protrude outwardly from each side of the frame units 10A, 10B.

[0050] The balcony 50 may or may not be provided, and may be configured in a wall shape rather than in a fence shape.

[0051] The building 100 may be a one-story building or a three or more-story building. [Explanation of symbols]
