[Technical field]

[0001] The present invention relates to a positioning structure for a unit building. [Background technology]

[0002] The following Patent Document 1 discloses an invention related to a modular building. In this modular building, adjacent joints between the frames of adjacent building units are connected by shear plates. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2014-20008 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the prior art described in Patent Document 1, the shear plate is arranged to straddle the adjacent joints, and the building units on the upper floors of the building units connected by the shear plate cannot be placed until the joints to be connected are connected, which is thought to reduce the freedom of construction of the building.

[0005] In consideration of the above, an object of the present invention is to provide a positioning structure for a unit building that can ensure freedom in the construction of the building. [Means for solving the problem]

[0006] The positioning structure of a unit building in the first aspect comprises a first positioning member having a first base portion arranged at a first joint portion provided at an end of a first pillar that constitutes part of the structure of a first building unit, and a first positioning portion located between the first joint portion and a second joint portion provided at an end of a second pillar that constitutes part of the structure of a second building unit adjacent to the first building unit when viewed from the building height direction; a second positioning member having a second base portion arranged at the second joint portion and a second positioning portion located between the first joint portion and the second joint portion when viewed from the building height direction; and a connecting portion that connects the first positioning portion and the second positioning portion.

[0007] In the positioning structure for unit buildings according to the first aspect, a first joint is provided at an end of a first pillar constituting a part of the structure of a first building unit, and a second joint is provided at an end of a second pillar constituting a part of the structure of a second building unit adjacent to the first building unit as viewed from the building height direction.

[0008] Incidentally, when constructing a unit building, it is necessary to determine the positioning of the first and second joints. However, if this positioning is performed using a member that spans the first and second joints, it is not possible to place a building unit above the first building unit or the second building unit until the first and second joints have been positioned.

[0009] Here, in this embodiment, the first and second joints are positioned by a first positioning member arranged relative to the first joint, a second positioning member arranged relative to the second joint, and the connecting portion.

[0010] In detail, the first positioning member has a first base portion and a first positioning portion, the first base portion is disposed at the first joint portion, and the first positioning portion is located between the first joint portion and the second joint portion.

[0011] On the other hand, the second positioning member includes a second base portion and a second positioning portion, the second base portion is disposed at the second joint portion, and the second positioning portion is located between the first joint portion and the second joint portion, and the first positioning portion and the second positioning portion are connected by a connecting portion.

[0012] Therefore, in this aspect, for example, when installing the first building unit, if the first positioning member is placed at the first joint portion, then after placing a building unit above the first building unit, the first positioning member can be connected to the second positioning member placed at the second joint portion of the second building unit by the connecting portion.

[0013] That is, in this aspect, after placing the building unit above the first building unit and the second building unit, the first and second connection portions can be positioned.

[0014] In the positioning structure of the unit building in the second aspect, the first base portion is shaped like a plate with its thickness direction in the building height direction and is arranged on the upper side of the building of the first joint portion, and the second base portion is shaped like a plate with its thickness direction in the building height direction and is arranged on the upper side of the building of the second joint portion.

[0015] In the positioning structure of a unit building according to the second aspect, the first base portion of the first positioning member is plate-shaped with its thickness direction in the building height direction, and is positioned above the first joint portion of the first building unit in the building height direction.

[0016] In addition, the second base portion of the second positioning member is formed in a plate shape with its thickness direction aligned in the building height direction, and is arranged above the second joint portion of the second building unit in the building height direction.

[0017] Therefore, in this aspect, the first base portion can be clamped between the first joint portion and the joint portion of the building unit arranged above the first building unit, and the second base portion can be clamped between the second joint portion and the joint portion of the building unit arranged above the second building unit. As a result, in this aspect, the first positioning member and the second positioning member can be arranged in a stably state.

[0018] The positioning structure for a unit building of the third aspect is the positioning structure for a unit building of the first or second aspect, wherein the first positioning portion is plate-shaped extending from the first base portion toward the second joint portion and has a first penetration portion penetrating in the building height direction, the second positioning portion is plate-shaped extending from the second base portion toward the first joint portion and has a second penetration portion penetrating in the building height direction, and the connecting portion has a first fitting portion that can be fitted into the first penetration portion from above in the building height direction, a second fitting portion that can be fitted into the second penetration portion from above in the building height direction, and a fixing portion to which the first fitting portion and the second fitting portion are fixed.

[0019] In the positioning structure of a unit building relating to the third aspect, the first positioning portion of the first positioning member is plate-shaped extending from the first base portion toward the second joint portion, and this first positioning portion is provided with a first penetration portion that penetrates in the height direction of the building.

[0020] In addition, the second positioning portion of the second positioning member is plate-shaped extending from the second base portion toward the first joint portion, and this second positioning portion is provided with a second penetration portion that penetrates in the height direction of the building.

[0021] The connecting portion has a first fitting portion, a second fitting portion, and a fixing portion, the first fitting portion is capable of fitting into the first penetration portion from above in the building height direction, the second fitting portion is capable of fitting into the second penetration portion from above in the building height direction, and the first fitting portion and the second fitting portion are fixed to the fixing portion.

[0022] Therefore, in this embodiment, the first fitting portion of the connecting portion can be fitted into the first penetration portion of the first positioning member from above in the building height direction, and the second fitting portion of the connecting portion can be fitted into the second penetration portion of the second positioning member from above in the building height direction, thereby connecting the first positioning member and the second positioning member.

[0023] Therefore, in this aspect, the work can be simplified compared to a configuration in which a fastening member is used to connect the first positioning member and the second positioning member.

[0024] The positioning structure of a unit building of the fourth aspect is the positioning structure of a unit building of the third aspect, wherein the first positioning portion is provided with a plurality of first penetration portions, the second positioning portion is provided with a plurality of second penetration portions, and the connecting portion is provided with the same number of first engagement portions as the number of first penetration portions and the same number of second engagement portions as the number of second penetration portions.

[0025] In the positioning structure for a unit building according to the fourth aspect, a first positioning portion of the first positioning member is provided with a plurality of first penetration portions, a second positioning portion of the second positioning member is provided with a plurality of second penetration portions, and the connecting portion is provided with first fitting portions in the same number as the number of first penetration portions, and second fitting portions in the same number as the number of second penetration portions.

[0026] Therefore, in this embodiment, the connecting portion and the first positioning member can be connected at multiple locations, and the connecting portion and the second positioning member can be connected at multiple locations, so that the first positioning member and the second positioning member can be connected in a more stable state.

[0027] The positioning structure for a unit building in the fifth aspect is a positioning structure for a unit building in any one of the first to fourth aspects, in which the first base portion and a first cover plate portion constituting a part of the upper side of the first connection portion in the building height direction are fixed by fastening a first fastening portion in the building height direction, and the second base portion and a second cover plate portion constituting a part of the upper side of the second connection portion in the building height direction are fixed by fastening a second fastening portion in the building height direction.

[0028] In the positioning structure of a unit building according to the fifth aspect, a portion of the upper side of the first joint portion in the building height direction is constituted by a first cover plate portion, and this first cover plate portion and the first base portion of the first positioning member are fixed together by fastening the first fastening portion in the building height direction.

[0029] In addition, a portion of the upper side of the second joint portion in the building height direction is formed by a second cover plate portion, and this second cover plate portion and the second base portion of the second positioning member are fixed together by fastening the second fastening portion in the building height direction.

[0030] Therefore, in this embodiment, the first positioning member can be disposed in the first joint in a more stable state, and the second positioning member can be disposed in the second joint in a more stable state.

[0031] The positioning structure of a unit building in the sixth aspect is a positioning structure of a unit building in any one of the first to fifth aspects, wherein the first base portion is arranged across the first joint portion and a third joint portion provided at the end of a third pillar that constitutes part of the main body of a third building unit adjacent to the first building unit in a direction perpendicular to the direction in which the first building unit and the second building unit are adjacent when viewed from the building height direction.

[0032] In the unit building positioning structure according to the sixth aspect, the first building unit and the third building unit are adjacent to each other in a direction perpendicular to the direction in which the first building unit and the second building unit are adjacent to each other when viewed from the building height direction.

[0033] The first base portion of the first positioning member is positioned across the first joint portion and a third joint portion provided at the end portion of a third pillar that forms part of the structure of the third building unit.

[0034] Therefore, in this aspect, for example, if the installation dates of the first building unit and the third building unit are the same, when these building units are installed, the first positioning member can be placed across the first and third joint portions and the first positioning member can be used to connect the first and third joint portions. Then, on the installation date of the second building unit which is different from the installation dates of the first building unit and the third building unit, the first and second joint portions can be positioned by connecting the first and second positioning members.

[0035] Therefore, in this aspect, when positioning a plurality of building units, if there are building units that were installed on the same date, the work of connecting the joints can be simplified.

[0036] The positioning structure for a unit building of the seventh aspect is the positioning structure for a unit building of the second aspect, wherein the first positioning portion is plate-shaped extending from the first base portion toward the second connection portion and comprises a first penetration portion penetrating in the building height direction, the second positioning portion is plate-shaped extending from the second base portion toward the first connection portion and comprises a second penetration portion penetrating in the building height direction, and the connecting portion comprises a first upper fastening member having a first shaft portion that can be inserted into the first penetration portion from above in the building height direction, a first lower fastening member fastened to the first shaft portion from below in the building height direction, a second upper fastening member having a second shaft portion that can be inserted into the second penetration portion from above in the building height direction, a second lower fastening member fastened to the second shaft portion from below in the building height direction, and a connecting plate having a third penetration portion through which the first shaft portion can be inserted and a fourth penetration portion through which the second shaft portion can be inserted and arranged above the first positioning portion and the second positioning portion in the building height direction.

[0037] In the positioning structure of a unit building according to the seventh aspect, the first positioning portion of the first positioning member is plate-shaped extending from the first base portion toward the second joint portion, and this first positioning portion is provided with a first penetration portion that penetrates in the height direction of the building.

[0038] In addition, the second positioning portion of the second positioning member is plate-shaped extending from the second base portion toward the first joint portion, and this second positioning portion is provided with a second penetration portion that penetrates in the height direction of the building.

[0039] The connecting portion includes a first upper fastening member, a first lower fastening member, a second upper fastening member, a second lower fastening member, and a connecting plate.

[0040] In detail, the first upper fastening member has a first shaft portion that can be inserted into the first penetration portion from above in the building height direction, and the first lower fastening member is fastened to the first shaft portion from below in the building height direction. The second upper fastening member has a second shaft portion that can be inserted into the second penetration portion from above in the building height direction, and the second lower fastening member is fastened to the second shaft portion from below in the building height direction.

[0041] Furthermore, the connecting plate is positioned above the first positioning portion and the second positioning portion in the building height direction, and this connecting plate is formed with a third through portion through which the first shaft portion can be inserted and a fourth through portion through which the second shaft portion can be inserted.

[0042] Therefore, in this aspect, with the first shaft portion of the first upper fastening member inserted into the first through-hole of the first positioning portion and the third through-hole of the connecting plate from above in the building height direction, the first lower fastening member can be fastened to the first shaft portion from below in the building height direction. Also, with the second shaft portion of the second upper fastening member inserted into the second through-hole of the second positioning portion and the fourth through-hole of the connecting plate from above in the building height direction, the second lower fastening member can be fastened to the second shaft portion from below in the building height direction. As a result, in this aspect, the connecting plate can limit the relative displacement between the first positioning member and the second positioning member.

[0043] The positioning structure for a unit building of the eighth aspect is the positioning structure for a unit building of the second aspect, wherein the first positioning portion is plate-shaped extending from the first base portion toward the second joint portion and upward in the building height direction, and is provided with a first penetration portion penetrating in the thickness direction of the first positioning portion, the second positioning portion is plate-shaped extending from the second base portion toward the first joint portion and downward in the building height direction, is arranged below the first positioning portion in the height direction, and is provided with a second penetration portion penetrating in the thickness direction of the second positioning portion, and the connecting portion is provided with an upper fastening member having a shaft portion that can be inserted into the first penetration portion and the second penetration portion from above in the building height direction when the first penetration portion and the second penetration portion overlap, and a lower fastening member fastened to the shaft portion from below in the building height direction.

A fitting pin 108 is fixed to one side of the fixed plate 106 in the longitudinal direction, and a fitting pin 109 is fixed to the other side of the fixed plate 106 in the longitudinal direction.

[0081] The fitting pins 108 protrude downward in the height direction from the fixed plate 106, and are fitted into the through-holes 84 from above in the height direction. The fitting pins 108 are arranged at the same intervals as the intervals between the through-holes 84, and in the same number as the through-holes 84 (two).

[0082] On the other hand, like the fitting pins 108, the fitting pins 109 also protrude downward in the height direction, and are fitted into the through-holes 100 from above in the height direction. The fitting pins 108 are arranged at the same intervals as the through-holes 100, and in the same number (two) as the through-holes 100.

[0083] <Actions and Effects of the Present Embodiment> Next, the operation and effects of this embodiment will be described.

[0084] 4, in this embodiment, a first joint portion 50 is provided at the end of a first pillar 48 constituting part of the frame of the first building unit 46. Also, a second joint portion 56 is provided at the end of a second pillar 54 constituting part of the frame of a second building unit 52 adjacent to the first building unit 46 when viewed in the height direction.

[0085] Incidentally, when constructing the building 10, it is necessary to determine the positioning of the first connection portion 50 and the second connection portion 56. However, if this positioning is performed using a member that spans the first connection portion 50 and the second connection portion 56, the building unit 12 cannot be placed above the first building unit 46 or the second building unit 52 until the first connection portion 50 and the second connection portion 56 have been positioned.

[0086] Here, in this embodiment, as shown in Figures 1 and 2, the first joint portion 50 and the second joint portion 56 are positioned by a positioning member 34 arranged relative to the first joint portion 50, a positioning member 36 arranged relative to the second joint portion 56, and a connecting portion 38.

[0087] In detail, the positioning member 34 has a base portion 34A and a positioning piece portion 34B, the base portion 34A is disposed at the first joint portion 50, and the positioning piece portion 34B is located between the first joint portion 50 and the second joint portion 56.

[0088] On the other hand, the positioning member 36 includes a base portion 36A and a positioning piece portion 36B, where the base portion 36A is disposed at the second joint portion 56, and the positioning piece portion 36B is located between the first joint portion 50 and the second joint portion 56. The positioning piece portion 34B and the positioning piece portion 36B are connected by a connecting portion 38.

[0089] Therefore, in this embodiment, for example, when installing the first building unit 46, if the positioning member 34 is placed in the first joint portion 50, then after placing the building unit 12 on the upper side of the first building unit 46, the positioning member 34 and the positioning member 36 placed in the second joint portion 56 of the second building unit 52 can be connected by the connecting portion 38.

[0090] That is, in this embodiment, after the building unit 12 is placed above the first building unit 46 and the second building unit 52, the first connection portion 50 and the second connection portion 56 can be positioned.

[0091] In this embodiment, as shown in FIG. 3, the base portion 34A of the positioning member 34 is plate-shaped with the thickness direction being the height direction, and is positioned vertically above the first joint portion 50 of the first building unit 46.

[0092] Further, the base portion 36A of the positioning member 36 is formed in a plate shape with its thickness direction being its height direction, and is disposed on the height direction side of the second joint portion 56 of the second building unit 52.

[0093] For this reason, in this embodiment, the base portion 34A can be clamped between the first joint portion 50 and the joint portion 26 of the building unit 12 arranged above the first building unit 46, and the base portion 36A can be clamped between the second joint portion 56 and the joint portion 26 of the building unit 12 arranged above the second building unit 52. As a result, in this embodiment, the positioning members 34 and 36 can be arranged in a stably state.

[0094] In addition, in this embodiment, the positioning piece 34B of the positioning member 34 is plate-shaped extending from the base portion 34A toward the second joint portion 56, and this positioning piece 34B is provided with a through-hole 84 that penetrates in the height direction.

[0095] Further, the positioning piece 36B of the positioning member 36 is formed in a plate shape extending from the base portion 36A toward the first joint portion 50, and this positioning piece 36B is provided with a through-hole 100 that penetrates in the height direction.

[0096] The connecting portion 38 is equipped with an engagement pin 108, an engagement pin 109, and a fixed plate 106, and the engagement pin 108 is capable of engaging with the through portion 84 from above in the height direction, and the engagement pin 109 is capable of engaging with the through portion 100 from above in the height direction, and the engagement pins 108 and 109 are fixed to the fixed plate 106.

[0097] Therefore, in this embodiment, the positioning members 34 can be connected to each other by engaging the mating pin 108 of the connecting portion 38 with the through portion 84 of the positioning member 34 from above in the height direction, and engaging the mating pin 109 of the connecting portion 38 with the through portion 100 of the positioning member 36 from above in the height direction.

[0098] Therefore, in this embodiment, the work can be simplified compared to a configuration in which a fastening member is used to connect the positioning members 34 and 36.

[0099] In this embodiment, a plurality of through-holes 84 are provided in the positioning piece 34B of the positioning member 34, and a plurality of through-holes 100 are provided in the positioning piece 36B of the positioning member 36. Then, the connecting portion 38 is provided with fitting pins 108 in the same number as the through-holes 84, and fitting pins 109 in the same number as the through-holes 100.

[0100] Therefore, in this embodiment, the connecting portion 38 and the positioning member 34 can be connected at multiple locations, and the connecting portion 38 and the positioning member 36 can be connected at multiple locations. As a result, in this embodiment, the positioning members 34 and 36 can be connected in a more stable state.

[0101] In addition, in this embodiment, a portion of the upper vertical side of the first joint portion 50 is formed by the first cover plate portion 60, and this first cover plate portion 60 and the base portion 34A of the positioning member 34 are fixed together by fastening the first fastening portion 86 in the vertical direction.

[0102] In addition, a portion of the upper vertical side of the second joint portion 56 is formed by the second cover plate portion 68, and this second cover plate portion 68 and the base portion 36A of the positioning member 36 are fixed together by fastening the second fastening portion 98 in the vertical direction.

[0103] For this reason, in this embodiment, the positioning member 34 can be arranged in the first joint portion 50 in a more stable state, and the positioning member 36 can be arranged in the second joint portion 56 in a more stable state.

[0104] In this manner, in this embodiment, the degree of freedom in the construction of the building 10 can be ensured.

[0105] <Second embodiment> Hereinafter, the positioning structure of a unit building according to the second embodiment of the present invention will be described with reference to Fig. 7. Note that the same components as those in the first embodiment described above are given the same reference numbers and the description thereof will be omitted.

[0106] This embodiment is characterized in that at the location where four joint sections 26 in the building 10 are gathered, these joint sections 26 are connected by a pair of "positioning members 110" as first positioning members, a pair of "positioning members 112" as second positioning members, and four connecting sections 38.

[0107] Specifically, the positioning member 110 is arranged for one of the joint portions 26 located on one side in the longitudinal direction and the other side in the span direction, and for one of the joint portions 26 located on the other side in the longitudinal direction and one side in the span direction.

[0108] On the other hand, the positioning members 112 are arranged for the joint portions 26 that are located on one side in the girder direction and one side in the span direction, and for the joint portions 26 that are located on the other side in the girder direction and the other side in the span direction.

[0109] The positioning member 110 has a basically similar configuration to the positioning member 34, and includes a "base portion 110A" as a first base portion, and "positioning piece portion 110B" and "positioning piece portion 110C" as first positioning portions.

[0110] When viewed from the height direction, the apex angle of the base portion 110A is on the center C side of the four joint portions 26, and the peripheral portion 110A1 along one equal side extends along the ceiling girder 22, and the peripheral portion 110A2 along the other equal side extends along the ceiling girder 24.

[0111] The positioning piece 110B is provided on a portion of the peripheral portion 110A1 on the side of the center C, and the positioning piece 110C is provided on a portion of the peripheral portion 110A2 opposite the center C.

[0112] On the other hand, the positioning member 112 is basically configured in the same manner as the positioning member 36, and is configured to include a "base portion 112A" as a second base portion, and "positioning piece portion 112B" and "positioning piece portion 112C" as second positioning portions.

[0113] When viewed from the height direction, the apex angle of the base portion 112A is on the center C side, and a peripheral portion 112A1 along one equal side extends along the ceiling girder 22, and a peripheral portion 112A2 along the other equal side extends along the ceiling girder 24.

[0114] The positioning piece 112B is provided on a portion of the peripheral portion 112A1 opposite the center C, and the positioning piece 112C is provided on a portion of the peripheral portion 112A2 on the center C side.

[0115] The positioning piece 110B is connected to the positioning piece 112B by a connecting portion 38, and the positioning piece 110C is connected to the positioning piece 112C by a connecting portion 38.

[0116] With this configuration, when used in conjunction with the first embodiment described above, it becomes possible, for example, to stack the building units 12 in the row furthest on the other side of the girder direction of the building 10 shown in Figure 6 in the vertical direction and waterproof them, and then install the building units 12 in the row on one side of the girder direction of these building units 12.

[0117] <First Modification of Second Embodiment> Hereinafter, a positioning structure for a unit building according to a first modified example of the second embodiment of the present invention will be described with reference to FIG.

[0118] In this modified example, a "positioning member 114" is provided as a first positioning member in which the positioning members 110 and 112 are integrated. This positioning member 114 is disposed across one of the joint portions 26 located on one side in the girder direction and one side in the span direction, and another located on the other side in the girder direction and one side in the span direction.

[0119] In detail, the positioning member 114 includes a "base portion 114A" as a first base portion, and "positioning piece portion 114B" and "positioning piece portion 114C" as first positioning portions.

[0120] The base portion 114A includes a base piece portion 114A1 having a similar configuration to the base portion 110A, a base piece portion 114A2 having a similar configuration to the base portion 112A, and a connection piece portion 114A3 connecting these together.

[0121] The positioning piece 114B has a similar configuration to the positioning piece 110B and is integral with the base piece 114A1, and the positioning piece 114C has a similar configuration to the positioning piece 112B and is integral with the base piece 114A2.

[0122] In this modified example, the positioning members 110 and 112 on the other side in the inter-beam direction function as second positioning members.

[0123] According to this configuration, if the building units 12 adjacent in the girder direction have the same installation date, when these building units 12 are installed, the positioning member 114 can be placed across the joints 26 adjacent in the girder direction and these joints 26 can be connected by the positioning member 114. Then, on the installation date of a building unit 12 located on the other side of the two building units 12 in the beam direction and having a different installation date from these building units 12, the positioning member 114, the positioning member 110 and the positioning member 112 can be connected to position the four joints 26 gathered in one place.

[0124] Therefore, in this embodiment, when positioning a plurality of building units 12, if there are building units 12 that were installed on the same date, the work of connecting the joints 26 can be simplified.

[0125] <Second Modification of Second Embodiment> Hereinafter, a positioning structure for a unit building according to a second modified example of the second embodiment of the present invention will be described with reference to FIG.

[0126] In this modified example, a "positioning member 116" is provided as a first positioning member in which a pair of positioning members 110 and 112 are integrated. This positioning member 116 is disposed across three of the joints 26 excluding the one located on the other side in the girder direction and the other side in the inter-beam direction among the joints 26.

[0127] In detail, the positioning member 116 includes a "base portion 116A" as a first base portion, and a "positioning piece portion 116B" as a first positioning portion.

[0128] The base portion 116A includes a base piece portion 116A1 having a similar configuration to the base portion 110A and arranged relative to the joint portion 26 on the other side in the girder direction and on one side in the inter-beam direction, a base piece portion 116A2 having a similar configuration to the base portion 112A and located on one side in the inter-beam direction of the base piece portion 116A1, a base piece portion 116A3 having a similar configuration to the base portion 110A and located on the other side in the inter-beam direction of the base piece portion 116A2, a connecting piece portion 116A4 connecting the base piece portion 116A1 and the base piece portion 116A2, and a connecting piece portion 116A5 connecting the base piece portion 116A2 and the base piece portion 116A3.

[0129] The positioning piece 116B has the same configuration as the positioning piece 110C and is provided integrally with the base piece 116A3.

[0130] In this modified example, the positioning member 112 arranged at the joint portion 26 located on the other side in the girder direction and the other side in the beam direction among the joint portions 26 functions as a second positioning member.

[0131] According to this configuration, when positioning a plurality of building units 12, if there are three building units 12 that were installed on the same date, the work of connecting the joints 26 can be simplified.

[0132] <Third Modification of Second Embodiment> Hereinafter, a positioning structure for a unit building according to a third modified example of the second embodiment of the present invention will be described with reference to FIG.

[0133] This modified example includes the above-mentioned positioning member 114 which functions as the first positioning member, and a "positioning member 118" which serves as a second positioning member and is arranged across the joint portion 26 which is located on one side in the girder direction and one side in the span direction, and the joint portion 26 which is located on the other side in the girder direction and the other side in the span direction.

[0134] In detail, the positioning member 118 includes a "base portion 118A" as a second base portion, and "positioning piece portion 118B" and "positioning piece portion 118C" as second positioning portions.

[0135] The base portion 118A is configured symmetrically with the base portion 114A. The positioning piece 118B is configured similarly to the positioning piece 110B, is located on the other side of the positioning piece 114B in the girder direction, and is provided integrally with the base portion 118A. The positioning piece 118C is configured similarly to the positioning piece 112B, is located on the other side of the positioning piece 114C in the girder direction, and is provided integrally with the base portion 118A.

[0136] According to this configuration, when positioning a plurality of building units 12, if there are two sets of building units 12 that were installed on the same date, the work of connecting the joints 26 can be simplified.

[0137] <Third embodiment> Hereinafter, the positioning structure of a unit building according to the third embodiment of the present invention will be described with reference to Fig. 11. Note that the same components as those in the first and second embodiments described above will be given the same reference numbers and the description thereof will be omitted.

[0138] A feature of the building 10 is that at locations where three joints 26 are gathered, these joints 26 are connected by positioning members 34, 36, 110 and two connecting portions 38.

[0139] Specifically, the positioning member 34 is arranged in the joint section 26 located on the other side of the girder direction and the other side of the span direction, the positioning member 36 is arranged in the joint section 26 located on one side of the girder direction and one side of the span direction, and the positioning member 110 is arranged in the joint section 26 located on the other side of the girder direction and one side of the span direction.

[0140] The positioning member 34 and the positioning member 110 are connected to each other by a connecting portion 38, and the positioning member 34 and the positioning member 110 are connected to each other by a connecting portion 38. In this modified example, the positioning member 34 and the positioning member 36 function as a first connecting member, and the positioning member 110 functions as a second connecting member.

[0141] According to this configuration, basically the same actions and effects as those of the second embodiment described above are achieved.

[0142] <First Modification of the Third Embodiment> Hereinafter, a positioning structure for a unit building according to a first modified example of the third embodiment of the present invention will be described with reference to FIG.

[0143] This modified example includes a "positioning member 120" as a first positioning member having a configuration similar to that of positioning member 114. This positioning member 120 is configured by omitting positioning piece 114C from positioning member 114, and includes a "base portion 120A" as a first base portion and a "positioning piece portion 120B" as a first positioning portion.

[0144] In this modification, the positioning member 120 is disposed across one of the joints 26 located on one side in the longitudinal direction and one side in the span direction, and another of the joints 26 located on the other side in the longitudinal direction and one side in the span direction. The positioning member 34 also functions as a second connecting member.

[0145] With this configuration, when positioning a plurality of building units 12, the work of connecting the joints 26 can be simplified when building units 12 installed on the same date are in the girder direction.

[0146] <Second Modification of Third Embodiment> Hereinafter, a positioning structure for a unit building according to a second modified example of the third embodiment of the present invention will be described with reference to FIG.

[0147] In this modified example, a "positioning member 122" serving as a first positioning member having a configuration similar to that of positioning member 114. This positioning member 120 is configured by omitting positioning piece 114B from positioning member 114, and is configured to include a "base portion 122A" serving as a first base portion, and a "positioning piece portion 122B" serving as a first positioning portion.

[0148] In this modification, the positioning member 122 is disposed across the joint portion 26 located on the other side in the girder direction and on one side in the span direction, and the joint portion 26 located on the other side in the girder direction and on the other side in the span direction. The positioning member 36 also functions as a second connecting member.

[0149] With this configuration, when positioning a plurality of building units 12, if building units 12 installed on the same day are located in the beam direction, the work of connecting the joints 26 can be simplified.

[0150] <Fourth embodiment> Hereinafter, the positioning structure of a unit building according to the fourth embodiment of the present invention will be described with reference to Figures 14 and 15. Note that the same components as those in the first embodiment described above are given the same reference numbers and the description thereof will be omitted.

[0151] In this embodiment, the "connecting portion 150" that connects the positioning member 34 and the positioning member 36 includes a "connecting plate 152," two "bolts 154" as first upper fastening members, two "nuts 156" as first lower fastening members, two "bolts 158" as second upper fastening members, and two "nuts 160" as second lower fastening members.

[0152] In detail, the connecting plate 152 is in the shape of a rectangular plate, and is disposed with its plate thickness direction as its height direction and its longitudinal direction as its inter-beam direction. Also, in a portion on the other side in the inter-beam direction of the connecting plate 152, a plurality (two, for example) of "through portions 162" as third through portions formed similarly to the through portion 84 are formed at intervals in the inter-beam direction, and in a portion on one side in the inter-beam direction of the connecting plate 152, a plurality (two, for example) of "through portions 164" as fourth through portions formed similarly to the through portion 100 are formed at intervals in the inter-beam direction.

[0153] The connecting plate 152 configured as described above is positioned vertically above the positioning pieces 34B and 36B so that, when viewed from the height direction, the through-holes 84 and the through-holes 162 overlap, and the through-holes 100 and the through-holes 164 overlap, respectively.

[0154] Then, a "shaft portion 154A" as a first shaft portion of bolt 154 is inserted into through portion 84 and through portion 162 from above in the height direction, and a nut 156 is fastened to shaft portion 154A from below in the height direction. Also, a "shaft portion 158A" as a second shaft portion of bolt 158 ​​is inserted into through portion 100 and through portion 164 from above in the height direction, and a nut 160 is fastened to shaft portion 158A from below in the height direction.

[0155] According to this configuration, the relative displacement between the positioning members 34 and 36 can be limited by the connecting plate 152. Also, since the connecting part 150 can be stored separately into the connecting plate 152, the bolt 154, the nut 156, the bolt 158, and the nut 160, it is easier to secure the space required for storing the parts compared to a configuration in which the connecting part is formed by joining a plurality of members.

[0156] <Fifth embodiment> Hereinafter, the positioning structure of a unit building according to the fifth embodiment of the present invention will be described with reference to Figures 16 and 17. Note that the same components as those in the first embodiment described above are given the same reference numbers and the description thereof will be omitted.

[0157] This embodiment is characterized in that a "positioning member 170" serving as a first positioning member is disposed in the first joint 50 instead of the positioning member 34, and a "positioning member 172" serving as a second positioning member is disposed in the second joint 56 instead of the positioning member 36, and these are connected by a "bolt 174" serving as an upper fastening member and a "nut 176" serving as a lower fastening member. That is, in this embodiment, the bolt 174 and the nut 176 function as a "connecting portion 178."

[0158] In detail, the positioning member 170 includes a "base portion 170A" serving as a first base portion having a similar configuration to the base portion 34A, and a "positioning piece portion 170B" serving as a first positioning portion.

[0159] The positioning piece 170B is in the form of a plate extending from the peripheral edge of the base portion 170A on the second joint portion 56 side toward the second joint portion 56 and upward in the height direction. In this positioning piece 170B, a plurality of (for example, two) "penetration portions 180" are formed at a predetermined interval in the inter-beam direction as first penetration portions penetrating the positioning piece 170B in the thickness direction. In addition, a spline hole 182 is formed in the central portion of the positioning piece 130B in the inter-beam direction, penetrating the positioning piece 170B in the thickness direction.

[0160] On the other hand, the positioning member 172 includes a "base portion 172A" serving as a second base portion having a similar configuration to the base portion 36A, and a "positioning piece portion 172B" serving as a second positioning portion.

[0161] As an example, the positioning piece 172B is in the form of a plate extending from the peripheral portion of the base portion 172A on the first joint portion 50 side toward the first joint portion 50 and downward in the height direction, and is disposed below the positioning piece 170B in the height direction so as to overlap with the positioning piece 170B. In this positioning piece 172B, a plurality of (for example, two) "penetrating portions 184" are formed at a predetermined interval in the inter-beam direction as second penetrating portions penetrating the positioning piece 172B in the thickness direction. In addition, a spline hole 186 is formed in the central portion of the positioning piece 172B in the inter-beam direction, penetrating the positioning piece 172B in the thickness direction.

[0162] Positioning members 170 and 172 are positioned by inserting a tool into blind holes 182 and 186, and are connected by inserting "shaft portion 174A" of bolt 174 through through-holes 180 and 184 from above in the height direction and fastening nut 176 to shaft portion 174A from below in the height direction.

[0163] According to such a configuration, the relative displacement between the positioning members 170 and 172 can be restricted without using a member connecting the positioning members 170 and 172.

[0164] <Supplementary explanation of the above embodiment> (1) In the above-described embodiment, the connecting portion is provided separately from the first positioning member and the second positioning member. However, the number of parts may be reduced by providing a connecting pin or the like on the first positioning member and the second positioning member.

[0165] (2) In addition, in the above-described embodiment, fastening parts including bolts and nuts were used to fix the first positioning member and the second positioning member to the joint portion, but rivets or the like may also be used to fix the first positioning member and the second positioning member to the joint portion.
