Description

  The present invention relates to a unit building configured by adjoining a plurality of building units.

  Conventionally, a unit building in which a plurality of building units manufactured in a factory are stacked vertically and horizontally is known. In general, these building units are connected in close proximity without providing a substantial gap except for the purpose of absorbing errors.

  On the other hand, Patent Documents 1 and 2 disclose unit buildings that can expand the building area beyond the limit of multiples of building units by providing a gap between the building units and connecting them. .

JP 2007-247343 A Japanese Patent No. 3796494

  However, in the unit buildings disclosed in Patent Documents 1 and 2, the horizontal rigidity of the unit building is ensured by arranging the cross beams or the structural plywood without gaps in the gaps between the building units. , Material costs increase. In addition, when a structural beam or a structural plywood is attached to the entire gap, it is difficult to remove the structural member even if piping is used between the beams, and maintenance such as piping repair is easy. I can't do it.

  Also, if the rigidity between the beams is increased too much over the entire length in the axial direction by using a crossing beam, the beam material of the building unit becomes difficult to bend, and the original characteristics of the frame structure that absorb energy by deformation are sufficient. There is a risk that it will not be able to be demonstrated.

  Therefore, an object of the present invention is to provide a unit building that can secure a space for piping between building units while maintaining the original characteristics of the frame structure.

  In order to achieve the above object, the unit building of the present invention is a unit building constituted by adjoining a plurality of building units each of which a framework is formed by a beam material and a column material, and between the opposing building units. The groove-shaped gap formed in the longitudinal direction is formed across a plurality of building units, and the reinforcing beam having a substantially C-shaped cross-sectional view extending in the longitudinal direction of the gap is open. It is spanned across a plurality of beam members in a state where the mouth is directed toward the center of the gap.

  Here, with respect to the C-shaped opening of the reinforcing beam, the overlapping reinforcing beams having a substantially C-shaped cross-sectional view can be arranged in parallel so that the opening ports face each other. Further, the reinforcing beam, the overlap reinforcing beam, and the beam material may be connected by a bolt portion that passes through them.

  Furthermore, the reinforcing beam can be bridged between beam members in which column members are not arranged at the corners of the building unit. Moreover, a pipe material can be arrange | positioned in the said clearance gap. Further, it is preferable that the gap has a width of 20-30 cm, and a floor panel is detachably installed across the beam members to be the floor beams of the building unit.

  Moreover, the said clearance gap can be made into the structure where the beam materials which oppose on both sides of the clearance gap are partially connected by the connection member. Here, the connection member may be configured to include a plurality of support members arranged at intervals in the longitudinal direction of the gap, and a connection surface material spanned between the support members. . Furthermore, the support material may be configured such that both ends are fixed to the side surface side of the beam material with a length adjusted by a length adjusting means.

  The unit building of the present invention configured as described above bridges a substantially C-shaped reinforcing beam in cross section across a plurality of beam members so that the opening is directed toward the center of the gap.

  For this reason, the area | region where a reinforcement beam occupies a clearance gap decreases, and it can pipe and use various pipe materials in a clearance gap effectively. In addition, a structure that spans a reinforcing beam along the axial direction of the beam can bend the beam of the building unit when a large earthquake occurs. The original structural property of absorbing energy can prevent the unit building from collapsing.

  In addition, if the C-shaped opening of the reinforcing beam is overlapped with the C-shaped opening of the reinforcing beam so as to face each other, the area where the reinforcing structure occupies the gap can be minimized. The gap can be used effectively as a space for piping.

  Furthermore, if the connection between the reinforcing beam, the overlapped reinforcing beam, and the beam material is performed by a bolt portion penetrating them, it can be easily implemented. In addition, by forming the reinforcing structure straddling between the building units in this way, a large indoor space straddling between the building units where there is no column material can be formed.

  Furthermore, if the gap is 20-30 cm wide, the floor panel can be installed across the floor beams without reinforcing the floor panel and increasing the rigidity. In addition, if the floor panel is detachable, maintenance such as repair or replacement of the piping or the reinforcing structure can be easily performed. Here, the gap having a width of 20-30 cm is a distance at which the floor substrate can be directly bridged without performing any special reinforcement on the floor substrate to be passed to the gap.

  In addition, when the beam members facing each other in the gap between the building units are partially connected by the connecting member, the shear direction between the building units and the deformation in the width direction of the gap are restricted at the place where the connecting members are arranged. The On the other hand, deformation in the shear direction and the width direction of the gap is allowed between the connecting members.

  In this way, if the deformation of the beam material in the shear direction between the building units and the width direction of the gap is partially constrained, it is not necessary to arrange structural members in other parts, and the structure is simplified. Can do.

  Further, if the connecting member is constituted by a plurality of support members arranged at intervals in the longitudinal direction of the gap, and a connecting surface material spanned between the support members, a relative building unit is supported by the support member. In addition to restraining deformation in the shear direction, deformation in the width direction of the gap can be restrained by the connecting surface material spanned between the support members.

  Further, if the plurality of support members are connected by the connecting surface material, the horizontal connection between the beam members is performed on the surface, and even if a horizontal force is applied, the unit building is not easily twisted.

  In addition, if the support member is provided with a length adjusting means, even if a slight error occurs in the width of the gap between the building units, the support member can be easily adjusted between the beam members by adjusting the length adjusting means. Can be bridged to.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a cross-sectional view illustrating a configuration of a reinforcing structure of a unit building 10 according to the present embodiment, and FIG. 2 is a plan view illustrating a schematic configuration of the unit building 10 including the reinforcing structure. 3 and 4 are diagrams for explaining the structure of the connecting structure between the building units.

  First, the structure of the unit building 10 will be described with reference to FIG. 2. Such a unit building 10 is constructed by joining a plurality of building units 1A-1F manufactured at a factory on site.

  Here, a plan view of the second floor of the unit building 10 will not be described, but building units 1,... Having the same configuration are placed on the first floor building units 1A-1F as shown in FIG. Placed. In the following description, the building units 1A to 1F will be collectively described as the building unit 1 when it is not necessary to specify the position.

  Such a building unit 1 includes a pillar 11 as a pillar material arranged from two corners to four corners, and a floor beam 12 as a beam material spanned between the lower ends of the pillars 11. Are formed into a box-shaped frame structure (framework structure) by the ceiling beams 13, 13A,..., Which are bridged between the upper ends of the columns 11,. . Here, the beam material on the long side is the floor beam 12 or the ceiling beam 13, and the beam material on the short side is the floor beam 12A or the ceiling beam 13A.

  The column 11 is formed of a square steel pipe, the floor beam 12 and the ceiling beam 13 are formed of a substantially C-shaped steel material in cross section, and the column 11, the floor beam 12 (12A), and the ceiling beam 13 (13A) are joined frame members 14. It is joined via.

  As shown in FIGS. 3 and 4, the joining frame member 14 includes a column contact surface 14 a that contacts the side surface of the column 11, and a beam contact surface 14 b that contacts the side surface of the floor beam 12 or the ceiling beam 13. Are formed so as to be substantially orthogonal.

  Then, the column contact surface 14a of the joining frame member 14 is brought into contact with the side surface of the column 11 and welded, and the floor beams 12 (12A) or the ceiling beams 13 ( 13A) are brought into contact with each other and welded together.

  The unit building 10 shown in FIG. 2 is a building in which a groove-like gap is formed between the beam members on both the long side and the short side. That is, gaps 101,... Of about 20-30 cm are formed between the long side building units 1A, 1B, 1B, 1C, 1D, 1E, 1E, 1F, respectively.

  In addition, gaps 102 of about 20-30 cm are formed between the building units 1A, 1D, 1B, 1E, 1C, 1F on the short side. For example, the gap 102 between the building units 1A and 1D is formed across the plurality of building units 1B, 1E, 1C, and 1F by extending in the longitudinal direction of the gap 102.

  As shown in FIG. 3, the connecting member 2 is arranged in the gap 101 on the long side formed in this way. The connecting member 2 is disposed between the facing ceiling beams 13 and 13 in the vicinity of the corners of the building units 1A and 1B where the joints between the columns 11 and the ceiling beams 13 are formed.

  Moreover, since this connection member 2 is each arrange | positioned in the vicinity of a junction part, between a pair of building units 1A and 1B arranged in parallel, the connection member 2 is provided at two locations near both ends in the axial direction of the ceiling beam 13. , 2 are arranged. A groove-like space is formed between the connecting members 2 and 2 along the axial direction of the ceiling beam 13.

  Furthermore, if the arrangement position of this connection member 2 is demonstrated in detail, it will arrange | position in the position where the joining frame material 14 which joins the pillar 11 and the ceiling beam 13 is provided.

  The connecting member 2 includes a plurality of support members 21A and 21B arranged at intervals in the longitudinal direction of the gap 101 (the axial direction of the ceiling beam 13), and a connecting surface spanned between the support members 21A and 21B. The material 24 is provided.

  The supporting members 21A and 21B are attached to the side surface of the joining frame member 14 that joins the column 11 and the ceiling beam 13, and one supporting member 21A is attached in the vicinity of the column 11 and the other supporting member 21B. Is attached in the vicinity of the edge of the joining frame member 14.

  These support members 21A and 21B are provided with female screw holes 212 and 212 at both ends of, for example, a hexagonal column-shaped main body 211, and the female screw holes 212 are formed from the inside of the ceiling beam 13 as shown in FIG. Bolts 22 are screwed in, and the support members 21A and 21B are fixed to the ceiling beam 13 via the joint frame member 14, respectively.

  That is, the lengths of the support members 21A and 21B are adjusted by the length of the bolt 22 to be screwed. Here, since one end of the support member 21A shown in FIG. 3 is fixed only by the bolts 22 and 22 because both ends of the main body portion 211 are in contact with the side surfaces of the joint frame members 14 and 14, respectively, Since the shaft portion of the bolt 22 is exposed between the main body portion 211 and the joint frame member 14, the support member 21 </ b> B is fixed to the joint frame member 14 by fitting a nut 23 therein.

  Further, the connecting surface material 24 is formed into a substantially trapezoidal shape in plan view as shown in FIG. 3, and both edge portions which are upper and lower sides of the trapezoid are bent into a hook shape as shown in FIG. 21B is hooked. For this reason, even if the unit building 10 is deformed due to an earthquake or the like and a force is applied in a direction in which the interval between the support members 21A and 21B increases, the expansion of the interval between the support members 21A and 21B is suppressed by the restraint of the connecting surface material 24. It is done.

  Further, as shown in FIG. 3, the connecting surface member 24 having a substantially trapezoidal shape in plan view is easily disposed in the gap 101 and has a gap between the connecting frame members 14 and 14 in the vicinity of the support member 21B due to the tapered shape. Therefore, the nuts 23 and 23 can be easily tightened.

  In the above description, as shown in FIG. 2, the connecting members 2,... Arranged in the long side gap 101 have been described, but the short side gap 102 orthogonal to the gap 101 will be described below. .

  The gap 102 is formed between the building units 1A, 1D, 1B, 1E, 1C, and 1F on the short side. Then, a reinforcing structure over these gaps 102, 102, 102 is constructed using the reinforcing beam 5.

  As shown in FIGS. 1 and 2, the reinforcing beams 5 are building units 1A, 1B, 1C (1D, 1E, 1F) arranged with a gap 101 in the axial direction of the ceiling beam 13A or the floor beam 12A on the short side. Arranged between them.

  As shown in FIG. 1, the reinforcing beam 5 is formed in a substantially C shape in sectional view, and the web of the reinforcing beam 5 is brought into contact with the side surface 131 of the ceiling beam 13 </ b> A via the thin plate 53. That is, the C-shaped opening of the reinforcing beam 5 faces the center side of the gap 102.

  The reinforcing beams 5 and 5 are connected by connecting members 2A,... As shown in FIGS. That is, in the gap 102 on the short side, in the vicinity of the corner where the column 11 of the building unit 1A, 1C, 1D, 1F is located, the building unit 1A, 1D, 1C, 1F is connected by the connecting member 2 A structure is formed.

  On the other hand, in the vicinity of the corner portion without the pillar 11 of the building unit 1A-1F, a connecting structure by the connecting member 2A is formed between the building units 1A, 1D, 1B, 1E, 1C, and 1F.

  As shown in FIG. 1, the connecting member 2A is bridged between the reinforcing beams 5 and 5 at positions where the ceiling beams 13A and 13A are disposed on the back side. Since the connecting member 2A has the same configuration as the connecting member 2 except that the reinforcing beams 5 and 5 are connected to each other, detailed description thereof is omitted.

  Further, between the reinforcing beams 5 and 5 of the gap 102, as shown in FIG. 1, a pipe material 4 such as a water supply pipe, a drain pipe, an air supply pipe, an exhaust pipe, and an air conditioning pipe can be piped.

  And when it pipes in the clearance gap 102 in this way, maintenance management, such as inspection or repair of the pipe material 4, can be easily performed only by removing the floor panel 32 and the ceiling board 34. That is, since the ceiling beams 13A and 13A are vertically communicated with each other between the connecting members 2 and 2A (2A and 2A), the piping can be exposed when the floor panel 32 and the ceiling plate 34 are removed.

  Furthermore, if it is between the connecting members 2 and 2A (2A and 2A) and between the reinforcing beams 5 and 5, even if the pipe is raised to the upper floor side or lowered to the lower floor side, the connecting structure and reinforcement Does not reduce the strength of the structure.

  Next, details of the configuration around the connecting member 2 will be described with reference to FIGS. Here, FIG. 5 is a plan view including the outer wall panel 31 around the gap 101 between the building units 1A and 1B.

  As shown in FIG. 5, the building units 1A and 1B are provided with outer wall panels 31A and 31A, respectively, and the gap 101 between the building units 1A and 1B is filled between the outer wall panels 31A and 31A. An outer wall panel 31 for a gap is attached to the gap. Further, a heat insulating material 331 such as glass wool is disposed inside the outer wall panels 31 and 31A, and an inner wall plate 33 is attached to the indoor side.

  6 is a cross-sectional view showing the configuration of the gap 101 on the long side between the building units 1 and 1, FIG. 6 (a) is a roof portion located at the upper part of the second floor, and FIG. 6 (b) is The floor of the second floor and the ceiling of the first floor, FIG. 6C is a diagram showing the configuration of the floor of the first floor.

  First, referring to FIG. 6A, the upper part of the ceiling beams 13 and 13 on the second floor is a roof portion covered with the folded plate roof 36, and the gap 101 between the ceiling beams 13 and 13 is connected to the ceiling 101. A member 2 is attached.

  Further, as shown in FIG. 6B, floor beams 12 and 12 on the second floor are placed on the upper surfaces of the ceiling beams 13 and 13 on the first floor, respectively. A floor board 32A is placed on the floor beam 322 passed to 12 via a joist 323.

  Further, a floor panel 32 is installed above the gap 101 between the building units 1 and 1 so as to be detachable between the floor beams 12 and 12. The floor panel 32 is composed of a cross joist 321 spanned between the floor beams 12 and 12 and a plate material such as a particle board stretched thereon. Here, if the gap 101 is about 20-30 cm, the floor panel 32 is made up of a crossed joist 321 (about 30 cm square) and a particle board (thickness about 15-20 mm) without special reinforcement. Can do.

  Further, the side surfaces 131 and 131 of the ceiling beams 13 and 13 on the first floor are connected by the connecting member 2, and the lower part thereof is closed by the ceiling plate 34. Here, the ceiling plate 34 is affixed to the lower surface of the crosspiece 341 spanning the ceiling beam 13.

  Further, as shown in FIG. 6C, the floor panel 32 is bridged between the floor beams 12 and 12 on the first floor, and the upper portion of the gap 101 between the building units 1 and 1 is closed.

  The gap 101 configured in this way is a closed space that is not exposed to the indoor side of the second floor or the indoor side of the first floor. Moreover, this gap | interval 101 is extended | stretched along the long side of building unit 1A-1F, as shown in FIG.

  That is, the gap 101 becomes a continuous long groove-like closed space, and even if piping of the pipe material 4 is performed in the gap 101, the appearance is not impaired and the indoor space is not eroded. Further, since the gap 101 is closed by the detachable floor panel 32, maintenance management such as repair or addition of piping can be easily performed.

  Next, the effect | action of the unit building 10 of this Embodiment is demonstrated.

  In the unit building 10 of the present invention configured as described above, the opposing ceiling beams 13 and 13 of the gap 101 between the building units 1 and 1 are connected by connecting members 2 and 2 at both ends in the longitudinal direction of the gap 101. The deformation in the shear direction between the building units 1 and 1 and the width direction of the gap 101 are restrained. Here, the deformation in the shear direction between the building units 1 and 1 means that a relative displacement between the building units 1 and 1 and the axial direction of the ceiling beam 13 occur. Moreover, the deformation | transformation of the width direction of the clearance gap 101 means that the displacement of the direction where the distance between the building units 1 and 1 approaches or leaves | separates arises.

  On the other hand, between the connecting members 2 and 2 in the longitudinal direction of the gap 101, a highly rigid structural member such as the connecting member 2 is not disposed along the axial direction of the ceiling beam 13. Deformation in the width direction is allowed.

  In this way, at both ends in the longitudinal direction of the gap 101, if the shear direction between the building units 1 and 1 and the deformation in the width direction of the gap 101 are constrained, it is necessary to arrange structural members in other portions. And a simple configuration with reduced material costs.

  Moreover, since the ceiling beams 13 and 13 can be bent at places other than the place where the connecting members 2 and 2 are arranged, the ceiling beam 13 constituting the frame structure (frame structure) is connected to the connecting members 2 and 2 when a large earthquake occurs. It is possible to prevent the unit building 10 from being damaged by being bent at the non-rigid portion in between and absorbing the earthquake energy by the deformation.

  That is, if the connecting member 2 is constituted by a plurality of supporting members 21A and 21B arranged at intervals in the axial direction of the ceiling beam 13, and a connecting face member 24 spanned between the supporting members 21A and 21B. In addition, the deformation in the shear direction between the relative building units 1 and 1 is restrained by the support members 21A and 21B, and the width of the gap 101 is deformed by the connecting surface material 24 spanned between the support materials 21A and 21B. Can be restrained.

  If the support members 21A and 21B are connected by the connecting surface member 24 in this way, the horizontal connection between the ceiling beams 13 and 13 is performed on the surface, and the unit is applied even if a horizontal force is applied. It is difficult for the building 10 to be twisted.

  Further, in the case of the supporting members 21A and 21B provided with the length adjusting means, even if a slight error occurs in the width of the gap 101 between the building units 1 and 1, it is easy to adjust by the length adjusting means. The support members 21A and 21B can be fixed between the ceiling beams 13 and 13.

  In particular, by joining the column 11 and the ceiling beam 13 via the joint frame member 14, the joint portion is reinforced, and by fixing the connecting member 2 via the joint frame member 14, A stronger connection structure can be obtained.

  And by providing the connection member 2 in the vicinity of the joint portion between the column 11 having a high strength and the ceiling beam 13 in this way, the ceiling beam 13 is prevented from being deformed by a horizontal force transmitted through the connection member 2. Can do.

  Further, if the gap 101 is 20-30 cm wide, the floor panel 32 can be installed across the floor beams 12, 12 even if the cross joist 321 of the floor panel 32 is a square member of about 30 cm square. .

  In the above description, the operation has been described using the gap 101 on the long side as an example, but the same applies to the gap 102 on the short side orthogonal to the gap 101 on the long side.

  Then, in the gap 102 on the short side, the reinforcing beam 5 having a substantially C-shaped cross-sectional view is bridged across the plurality of ceiling beams 13A, 13A, 13A so that the opening is directed to the center side of the gap 102. The space between the building units 1, 1, 1 can be reinforced.

  For example, a column 11 is erected in a space that spans between building units only by arranging normal building units, but a reinforcing structure that straddles between building units 1A, 1B, 1C (1D, 1E, 1F) By forming a large indoor space that spans between building units in which the pillars 11 do not exist can be formed.

  If the reinforcing beam 5 having a substantially C-shaped cross-sectional view, which is easy to increase the rigidity as compared with the plate material, is used, the area where the reinforcing structure occupies the gap 102 is reduced, and various pipe materials 4 are piped in the gap 102. It can be used effectively.

  Since the unit building 10 having the gaps 101 and 102 can be adjusted without the size limit of multiples of the building unit 1, the shape and floor plan of the unit building 10 can be freely designed. can do.

  Hereinafter, an example of a mode different from the above-described embodiment will be described with reference to FIGS. The description of the same or equivalent parts as those described in the above embodiment will be given the same reference numerals.

  In this example, the reinforcing reinforcing beam 51 described in the above-described embodiment is reinforced by arranging the overlapping reinforcing beams 51 having a substantially C-shaped cross-sectional view in parallel with each other so that the opening ports face each other. The structure will be described.

  As shown in FIGS. 2 and 7, the reinforcing beams 5 are building units 1A, 1B, 1C (1D, 1E, 1F) arranged with a gap 101 in the axial direction of the ceiling beam 13A or floor beam 12A on the short side. It is arranged between them.

  Further, as shown in FIG. 7, the reinforcing beam 5 is formed in a substantially C shape in a sectional view, and the web of the reinforcing beam 5 is brought into contact with the side surface 131 of the ceiling beam 13 </ b> A via the thin plate 53. Then, an overlapped reinforcing beam 51 having a substantially C-shaped cross-sectional view is disposed at the C-shaped opening of the reinforcing beam 5. In other words, the reinforcing beam 5 and the overlapping reinforcing beam 51 are disposed so that the C-shaped open ports face each other, and are formed in a rectangular shape in cross section.

  Then, the reinforcing beam 5 and the overlapping reinforcing beam 51 are connected and integrated by a bolt portion 52 as shown in FIG. The bolt portion 52 includes a bolt 521 that passes through the reinforcing beam 5, the lap reinforcing beam 51, and the ceiling beam 13 </ b> A, and a nut 522 that is attached to the bolt 521.

  Next, the details of the reinforcing structure using the reinforcing beam 6 in the gap 102 on the short side between the building units 1 and 1 will be described with reference to FIG. 8 which is a cross-sectional view of the ceiling portion on the second floor.

  In this reinforcing structure, the reinforcing beam 6 attached along the ceiling beam 13A on the second floor, the overlapping reinforcing beam 61 arranged in parallel to the reinforcing beam 6, and the reinforcing beam 6 and the overlapping reinforcing beam 61 are connected to the ceiling beam 13A. It is mainly comprised from the bolt part 52 to do.

  The reinforcing beam 6 is formed in a substantially C shape in a sectional view, and the web of the reinforcing beam 6 is brought into contact with the side surface 131 of the ceiling beam 13A via the thin plate 63. The overlap reinforcing beam 61 is formed in a substantially C shape in a sectional view, and is disposed so that the opening is opposed to the C opening of the reinforcing beam 6.

  The reinforcing beam 6 and the overlapping reinforcing beam 61 are connected and integrated by a bolt portion 62. The bolt portion 62 is configured by a bolt 621 that passes through the reinforcing beam 6, the overlapping reinforcing beam 61, and the ceiling beam 13 </ b> A, and a nut 622 attached to the bolt 621.

  In this way, in the gap 102 on the short side, the reinforcing beam 5 (6) and the overlapping reinforcing beam 51 (61) are connected to the ceiling beam 13A by the bolt portion 52 (62), so that the building units 1 and 1 are connected. Can be reinforced.

  For example, a column 11 is erected in a space that spans between building units only by arranging normal building units, but a reinforcing structure that straddles between building units 1A, 1B, 1C (1D, 1E, 1F) By forming a large indoor space that spans between building units in which the pillars 11 do not exist can be formed.

  In addition, if a substantially C-shaped member in cross-section is used for the reinforcing beam 5 (6) and the overlapping reinforcing beam 51 (61) is stacked on the C-shaped opening, the reinforcing structure occupies the gap 102. Therefore, various pipe materials 4 can be piped in the gap 102 and used effectively.

  Other configurations and functions and effects are substantially the same as those in the above-described embodiment, and thus description thereof is omitted.

  The embodiment of the present invention has been described in detail above with reference to the drawings. However, the specific configuration is not limited to the embodiment and the example, and the design change is within a range not departing from the gist of the present invention. Are included in the present invention.

  For example, in the embodiment and the example, the reinforcing structure (reinforcing beams 5, 6 etc.) straddling the building units 1A, 1B, 1C (1D, 1E, 1F) is provided in the gap 102 on the short side. However, the reinforcing structure may be provided in the gap 101 on the long side.

  That is, in the above-described embodiment, the connecting structure has been described while illustrating the gap 101 on the long side, and the reinforcing structure has been illustrated by illustrating the gap 102 on the short side, but is not limited thereto. A similar structure can be provided in any of the gaps 101 and 102.

  Moreover, in FIG. 2, although the edge part of the reinforcement beam 5 is the middle of building unit 1A, 1C (1D, 1F), it is not limited to this, Building unit 1A, 1C (1D, 1F) ) Can be arbitrarily set according to the required strength.

  Furthermore, in the said embodiment and Example, although the reinforcement structure was provided in order to abbreviate | omit one column 11 of building unit 1A-1F, it is not limited to this, When providing a cantilever balcony, A reinforcing structure using the reinforcing beams 5 and 6 described above can also be provided at the corners of the building unit 1 with the pillars 11.
