  By the way, although the unit size of a building unit is generally determined in several sizes, it is considered to use a building unit with an expanded unit size for just one outer wall to reflect recent customer needs. . In this case, since the positions and intervals of the pillars of the building unit are different from conventional ones, the loading structure of the transportation vehicle on the loading platform becomes complicated.

  In such a case, in transportation using the jig, it is necessary to newly manufacture a loading platform in which a fitting hole is formed at a position corresponding to the post-changed column position. Even if a transport vehicle having a loading platform corresponding to each building unit is prepared in advance, there may be a situation where it cannot be quickly handled due to a change in the operation rate of the transport vehicle.

  In consideration of the above facts, the present invention provides a building unit transportation jig and a building that can be loaded and transported on a transportation vehicle without changing the loading platform when transporting building units having different column positions and intervals. The purpose is to obtain a connecting structure for transporting the units.

  The building unit transportation jig according to the first aspect includes one surface that contacts the lower surface of the pillar of the building unit, the other surface that contacts the upper surface of the loading platform, the one surface, and the lower surface of the column. When contacting, the first fixing portion that determines and fixes the relative position in the surface direction between the one surface and the lower surface of the column, and the other surface and the upper surface of the loading platform come into contact with the loading platform in advance. The other surface so that the position in the surface direction of the formed fitting hole is different from the position in the surface direction of the hole previously formed in the lower surface of the pillar determined by the first fixing portion. And a second fixing portion that determines and fixes a relative position in the surface direction between the upper surface of the loading platform and the upper surface of the loading platform.

  The building unit transport jig includes one surface that contacts the lower surface of the pillar of the building unit and the other surface that contacts the upper surface of the loading platform. Therefore, when the building unit is loaded on the loading platform of the transportation vehicle and transported, the pillar is placed on the loading platform via one surface and the other surface of the building unit transportation jig. The building unit transportation jig includes a first fixing portion. The first fixing portion determines and fixes the relative position in the surface direction between the one surface and the lower surface of the column when the one surface contacts the lower surface of the column. Therefore, when the building unit is loaded on the loading platform and transported, the one surface of the building unit transporting jig and the lower surface of the column are fixed at relative positions determined in the surface direction. The building unit transportation jig includes a second fixing portion. The second fixing portion determines and fixes the relative position in the surface direction between the other surface and the upper surface of the loading platform when the other surface contacts the upper surface of the loading platform. Therefore, when the building unit is loaded on the cargo bed and transported, the other surface of the building unit transportation jig and the upper surface of the cargo bed are fixed at a relative position determined in the surface direction.

  Therefore, in the transportation using the building unit transportation jig, the relative position between one surface of the building unit transportation jig and the lower surface of the column and the relative position between the other surface of the building unit transportation jig and the upper surface of the loading platform. Both the positions are fixed in the plane direction. That is, the relative position between the upper surface of the loading platform and the lower surface of the pillar is fixed in the surface direction via one surface and the other surface of the building unit transport jig.

  Here, in this building unit transportation jig, the relative position in the surface direction between the other surface and the upper surface of the loading platform is determined by the position in the surface direction of the fitting hole formed in the loading platform in advance and the first fixing portion. It fixes so that the position of the surface direction of the hole previously formed in the lower surface of the pillar to do may become a different position. Therefore, when the building unit is loaded on the loading platform and transported, the fitting hole formed in advance in the loading platform and the hole formed in advance in the lower surface of the pillar are different in the surface direction.

  Therefore, according to this building unit transport jig, even if the positions of the fitting hole formed in the loading platform in advance and the hole formed in the lower surface of the column are displaced, the column of the building unit is mounted on the loading platform. The position in the surface direction (horizontal direction) can be fixed in the mounted state. That is, the building unit can be loaded and transported on the loading platform without preparing a loading platform in which a fitting hole corresponding to the position of the pillar is formed.

  The building unit transportation jig according to a second aspect is the hole according to the first aspect, wherein the first fixing portion penetrates from the one surface to the other surface and is provided in advance on the lower surface of the column. A bolt insertion hole in which the mounting bolt is fastened together, and the other surface side of the bolt insertion hole is expanded in diameter to accommodate the head of the mounting bolt, and the second fixing portion is And a bolt mounting hole which is opened from the other surface and into which the truck mounting bolt is screwed.

  In this aspect, the first fixing portion is a bolt insertion hole penetrating from one surface to the other surface, and the mounting bolt is fastened together in a hole provided in advance on the lower surface of the column. Therefore, with the hole provided in advance on the lower surface of the column and the bolt insertion hole aligned, the lower surface of the column is brought into contact with one surface, and the mounting bolt is inserted from the other surface side and tightened together As a result, the relative position in the surface direction between the one surface and the lower surface of the column is determined and fixed.

  In addition, the other surface side of the bolt insertion hole is expanded in diameter so that the head of the bolt can be accommodated. Therefore, the head of the bolt is accommodated in the expanded diameter portion, and the head of the mounting bolt from the other surface Does not protrude. Therefore, the head of the mounting bolt does not hinder the contact between the other surface and the upper surface of the loading platform.

  Thereby, the building unit transportation jig can be attached to the lower surface of the column with the mounting bolt in a state where the building unit is lifted. That is, regarding the procedure for loading the building unit, the mounting of the building unit transportation jig to the pillar can be performed prior to the mounting of the building unit transportation jig to the loading platform.

  The second fixing portion is a bolt mounting hole opened from the other surface, and a truck loading bolt is screwed into the second fixing portion. Therefore, fixing the relative position between the other surface and the upper surface of the loading platform is facilitated by fitting the truck loading bolts into fitting holes formed in advance in the loading platform. Thereby, after attaching the building unit transportation jig and the truck loading bolt to the pillar, it becomes easy to load the building unit on the loading platform.

  The building unit transportation jig according to the third aspect is, in the second aspect, the one surface side of the bolt insertion hole is also expanded in diameter to fit the head of the mounting bolt, The bolt mounting hole penetrates to the one surface.

  In this aspect, the bolt insertion holes are expanded in diameter so that the heads of the mounting bolts can be accommodated on both sides of the one surface side and the other surface side. Therefore, even if the mounting bolt is inserted from either of the one surface side and the other surface side, the head portion of the bolt is accommodated in the expanded diameter portion. Further, since the bolt mounting hole is a hole penetrating from the other surface to the one surface, the truck loading bolt can be screwed from any surface side. Thus, the building unit transportation jig can be used on both sides.

  The building unit transportation jig according to a fourth aspect is the positioning according to the first aspect, wherein the first fixing portion is erected from the one surface and inserted into a hole formed in advance in the pillar. The pin is a pin, and the second fixing portion is a bolt mounting hole that is opened from the other surface and into which the truck mounting bolt is screwed.

  In this aspect, the determination and fixing of the relative position in the surface direction between one surface of the building unit transport jig and the lower surface of the column is performed by inserting a positioning pin erected from one surface into a hole provided in advance in the column. It is done by doing. Therefore, regarding the procedure for loading the building unit, the building unit can be loaded after the building unit transport jig is attached to the loading platform. Thereby, in the state which lifted the building unit, the operation | work which attaches the jig | tool for transporting a building unit to the lower surface of a pillar with a mounting bolt can be omitted.

  In the building unit transportation jig according to the fifth aspect, in the first to fourth aspects, a plurality of the second fixing portions are present.

  In this aspect, when the other surface comes into contact with the upper surface of the loading platform, the second fixing portion that determines and fixes the relative position of each other can be selected from among the plurality of second fixing portions. Therefore, it is possible to indirectly select the relative position in the surface direction between the fitting hole of the loading platform and the column. Thereby, a plurality of types of building units having different column positions and intervals can be transported.

  The building unit transportation jig according to a sixth aspect is the fifth aspect, wherein the plurality of second fixing portions are arranged along a vehicle width direction when being placed on a cargo bed.

  In this aspect, the position which fixes a pillar changes in a vehicle width direction by using several 2nd fixing | fixed part properly. As a result, it is possible to transport a plurality of types of building units having different intervals between columns placed in the vehicle width direction during transportation, that is, intervals between columns in the wife direction.

  A building unit transportation jig according to a seventh aspect is constituted by a plurality of layers parallel to the one surface and the other surface in the first aspect to the sixth aspect, and at least one of them. The layer is made of an elastic material.

  In this aspect, the vibration input from the loading platform to the other surface of the building unit transport jig is attenuated by the layer made of the elastic material of the building unit transport jig, and the building unit transports from one surface to the building unit. Communicated. Thereby, the vibration transmitted to a building unit at the time of building unit transportation can be reduced.

The connecting structure for transporting the building unit according to the eighth aspect is formed in advance in the bolt insertion hole and the lower surface of the column provided in the building unit transporting jig of the second aspect or the third aspect. A hole is fastened together with the mounting bolt, so that the lower surface of the pillar and the one surface are connected, and the truck mounting bolt is screwed into the bolt mounting hole, so that the building unit The truck loading bolt is attached to a transportation jig, and the attached truck loading bolt is fitted in a fitting hole formed in advance in the loading platform, so that the other surface and the upper surface of the loading platform are And are connected.

(Operation and effect of this embodiment)
Next, the operation and effect of the present embodiment will be described through the description of the procedure for loading (connecting) the building unit 10 to the loading platform 30.

  As a loading procedure, first, the building unit 10 is lifted by a crane, and the building unit transport jig 50 is attached to the lower surface 20 </ b> B of the base plate 20 by the mounting bolts 56. Specifically, the upper surface 50A of the jig and the lower surface 20B of the base plate 20 are opposed to each other so that the bolt insertion hole 52 and the reference hole 22 are aligned, and the mounting bolt 56 is fixed to the jig 50 for transporting the building unit. The building unit transporting jig 50 is fastened to the base plate 20 by inserting from the side of the tool lower surface 50B.

  As described above, the bolt insertion hole 52 is inserted in the state where the mounting bolt 56 is aligned with the reference hole 22 of the base plate 20, so that the surface of the jig upper surface 50 </ b> A and the lower surface 20 </ b> B of the base plate 20 can be reduced. Determine and fix the relative position.

  Next, the truck loading bolt 40 is attached to the building unit transportation jig 50. Specifically, the screw portion 40B of the truck loading bolt 40 is inserted into the bolt mounting hole 54 of the building unit transporting jig 50 from the side of the jig lower surface 50B and screwed into the mounting hole 54b of the main body 60. . Note that this operation may be reversed in order from the above-described mounting operation using the mounting bolts 56.

  Subsequently, the building unit 10 is loaded on the loading platform 30. Specifically, in the building unit 10 with the building unit transportation jig 50 and the truck loading bolt 40 attached thereto, the fitting portion 40A of the truck loading bolt 40 is fitted into the fitting hole 32 of the loading platform 30. As shown in FIG. Further, the fixing bolt 34 is screwed into the hole formed by communicating the communication hole 42 of the truck loading bolt 40 and the fixing hole 36 of the loading platform 30 from below the loading platform, and the truck loading bolt 40 and the building unit. The building unit 10 is fixed to the loading platform 30 through the transportation jig 50.

  As described above, the bolt mounting hole 54 is formed by screwing the screw portion 40B of the truck loading bolt 40 having the fitting portion 40A that fits into the fitting hole 32 formed in the loading platform 30. The relative position in the surface direction between the lower surface 50B and the upper surface 30A of the loading platform 30 is determined and fixed.

  With the loading procedure described above, the building unit 10 is connected to the loading platform 30 of the transport vehicle, and the loading of the building unit 10 is completed.

Therefore, when the mounting bolt 56 is inserted into the bolt insertion hole 52, the head portion 56 </ b> A of the mounting bolt 56 is completely accommodated in the head insertion hole 52 c of the second vibration damping portion 62. As a result, the head 56 </ b> A of the mounting bolt 56 does not contact the loading platform 30 when the building unit transportation jig 50 with the mounting bolt 56 inserted is placed on the loading platform 30.

  Furthermore, in this embodiment, the shape of the fitting portion 40A of the truck loading bolt 40 is a shape obtained by inverting the substantially truncated cone shape. Therefore, it is easy to align the building unit 10 when loading it on the loading platform 30.

  Moreover, in this embodiment, the 1st damping part 58 and the 2nd damping part 62 of the jig | tool 50 for building unit transportation are formed with elastic materials, such as rubber | gum. Therefore, the vibration input to the jig lower surface 50B of the building unit transport jig 50 during the transportation of the building unit 10 is attenuated by the first vibration control unit 58 and the second vibration control unit 62. Then, it is transmitted to the building unit 10 from the jig upper surface 50A. As a result, vibration transmitted to the building unit 10 during transportation can be reduced.

  Furthermore, in this embodiment, the building unit transportation jig 50 includes three bolt mounting holes 54. Therefore, as shown in FIG. 4, by selecting the bolt mounting hole 54 for mounting the truck loading bolt 40, three patterns having different positional relationships between the mounting bolt 56 and the truck loading bolt 40 can be selected. Furthermore, the bolt mounting hole 54 is arranged along one direction. Therefore, a plurality of building units in which the interval between the pillars 16 corresponding to the vehicle width direction (usually, the interval in the wife direction) is different by being placed and used so that this direction and the vehicle width direction of the transport vehicle coincide with each other. It can be used for 10 transports.

  More specifically, in FIG. 5 (A), the left building unit transport jig 50 is used in the pattern of FIG. 4 (C), and the right building unit transport jig 50 is shown in FIG. ) Pattern. On the other hand, in FIG. 5 (B), the left building unit transportation jig 50 is used in the pattern of FIG. 4 (A) while using the same loading platform as in FIG. 5 (A). The building unit 100 in which the interval between the pillars 16 in the wife direction is wider than that of the building unit 10 in FIG. Thus, according to the building unit transportation jig 50 of the present embodiment, the building units 10 and 100 having different intervals between the pillars 16 can be transported without changing the loading platform 30. As a result, the cost of manufacturing a new loading platform 30 can be reduced, and the time for preparing the loading platform 30 can be reduced, enabling a quick response.

  In this state, that is, in a state where the building unit transportation jig 70 is placed on the loading platform 30, the positioning pins 72 of the building unit transportation jig 70 are inserted into the reference holes 22 provided in the base plate 20. The building unit 10 is loaded on the loading platform 30.

  As described above, the positioning pin 72 is inserted into the reference hole 22 of the base plate 20 to determine and fix the relative position in the surface direction between the upper surface 50 </ b> A of the jig and the lower surface 20 </ b> B of the base plate 20.

  As described above, in the second embodiment, with respect to the loading procedure, the step of attaching the building unit transportation jig 50 to the lower surface 20B of the base plate 20 while the building unit 10 is lifted by a crane or the like can be omitted.

  Moreover, since the positioning pin 72 is formed in a truncated cone shape at the upper end, the positioning of the base plate 20 is easy using the positioning pin 72. Further, in the second embodiment, the mounting bolt 56 is not used at the time of loading, and therefore it is not necessary to provide the head insertion hole 52c (the enlarged diameter portion 52R of the bolt insertion hole 52) as in the first embodiment. Therefore, the building unit transportation jig 70 has a two-layer structure including a vibration damping portion 74 and a main body portion 60.

[Supplementary explanation of the above embodiment]
In each embodiment mentioned above, although bolt insertion hole 52 and positioning pin 72 were explained as the 1st fixed part, the present invention is not limited to this. For example, a hole that does not penetrate to the lower surface of the jig may be used, and the shape of the hole may not be a cylindrical shape.

  Moreover, although the bolt attachment hole 54 was demonstrated as a 2nd fixing | fixed part, this invention is not limited to this. For example, the shape of the hole may not be cylindrical.

  Furthermore, although the example in which the bolt attachment hole 54 is a through hole has been described, the present invention is not limited to this. For example, the bolt mounting hole 54 may be opened from the jig lower surface 50B and can be screwed into the screw portion 40B of the truck loading bolt 40, and may not penetrate to the jig upper surface 50A.

  Moreover, although 1st Embodiment demonstrated the aspect in which the penetration hole 52a of the 1st damping part 58 was formed a little larger diameter than the screw part 40B of the mounting bolt 56, as a modification, the penetration hole 52a May be formed to have the same diameter as the head insertion hole 52c of the second vibration damping portion 62. In this case, the mounting bolt 56 can be inserted also from the jig upper surface 50A side of the building unit transport jig 50. Since the bolt mounting hole 54 is a through hole in the first place, the truck loading bolt 40 can be mounted not only from the jig lower surface 50B side but also from the jig upper surface 50A side. Therefore, the building unit transportation jig of this modification can be used on both sides.

  Further, although the case where three bolt attachment holes 54 are formed has been described, the application of the present invention is not limited to this, and only one may be formed, or two or four or more may be formed. Good. In the case of only one, when transporting building units with different column positions and intervals, the building unit transport with bolt mounting holes formed at other positions is not possible with only the building unit transport jig. This can be dealt with by manufacturing a jig. Therefore, cost can be held down compared with the case where a loading platform is newly manufactured.

  In addition, although the building unit transporting jigs 50 and 70 are configured by a plurality of layers made of different materials, the application of the present invention is not limited to this and may be configured by a single material.

  Furthermore, the size and shape of the building unit transportation jigs 50 and 70 have been described as being substantially the same size and shape as the shape of the base plate 20, but the application of the present invention is not limited to this, and the base plate 20 It can be changed as appropriate within the range in which it can be placed.

  Moreover, although what has the internal thread formed in the internal peripheral surface of the reference | standard hole 22 was demonstrated, the nut may be welded to the upper surface of the baseplate 20. FIG.
