The bearing portion 46 is disposed at a substantially central portion on the lower surface of the fixed plate 72, and an upper end portion thereof is fixed to the fixed plate 72 by welding. A plurality of reinforcing stiffeners 73 are provided around the bearing portion 46 on the lower surface side of the fixed plate 72. The stiffener 73 is made of a right-angled triangular steel plate. The stiffener 73 is disposed across the lower surface of the fixed plate 72 and the side surface (specifically, the corner) of the bearing portion 46, and is fixed to each surface by welding.

  Also in the support member 15, similarly to the support member 13, one side (lower side) of the connecting shaft portion 37 in the axial direction is screwed into the shaft hole 43 of the bearing portion 39 of the first fixing portion 35, and the connecting shaft portion The other side (upper side) of 37 in the axial direction is screwed into the shaft hole 53 of the bearing portion 46 of the second fixing portion 71. The height position of the second fixing portion 71 with respect to the first fixing portion 35 can be adjusted by rotating the connecting shaft portion 37 with respect to the fixing portions 35 and 71.

  Next, the configuration of the support member 16 disposed in the column assembly portion 33 in which the four columns 21 are assembled will be described with reference to FIG. FIG. 8A is an exploded front view showing the configuration of the support member 16, and FIG. 8B is a plan view showing the configuration. In FIG. 8, for the sake of convenience, members other than the support member 16 such as the columns 21 are indicated by virtual lines (two-dot chain lines).

  As shown in FIG. 8, the support member 16 has a second fixing portion 76 having a fixing plate 77 and a bearing portion 46 extending downward from the fixing plate 77. The fixed plate 77 is made of a flat steel plate, and has a square shape that straddles the lower ends of the four columns 21 constituting the column assembly portion 33. Above the fixed plate 77, the four columns 21 are mounted, and the column base plates 48 of the columns 21 are fixed to the fixed plate 77 by bolts 51 and nuts 52. Specifically, bolts 51 are inserted into holes provided in the overhanging portion 48 a of the column base plate 48 and holes 77 a provided in the fixing plate 77, and the bolt 51 is fastened to the nut 52. .

  The bearing portion 46 has the same configuration as the bearing portion 46 of the support member 13. For this reason, the same reference numerals as those of the bearing unit 46 are assigned and the description thereof is omitted. The bearing portion 46 is disposed at the center portion on the lower surface of the fixed plate 77, and the upper end portion thereof is fixed to the fixed plate 77 by welding. A plurality of reinforcing stiffeners 78 are provided around the bearing portion 46 on the lower surface side of the fixed plate 77. The stiffener 78 is made of a right-angled triangular steel plate. The stiffener 78 is disposed across the lower surface of the fixing plate 77 and the side surface (specifically, the corner portion) of the bearing portion 46, and is fixed to each surface by welding.

  Also in the support member 16, similarly to the support member 13, one side (lower side) of the connecting shaft portion 37 in the axial direction is screwed into the shaft hole 43 of the bearing portion 39 of the first fixing portion 35, and the connecting shaft portion The other side (upper side) of 37 in the axial direction is screwed into the shaft hole 53 of the bearing portion 46 of the second fixing portion 76. The height position of the second fixing portion 76 relative to the first fixing portion 35 can be adjusted by rotating the connecting shaft portion 37 with respect to the fixing portions 35 and 76.

  Next, an operation procedure for constructing the building 10 by installing each building unit 20 on the dirt floor 11 will be described. FIG. 9 is a diagram for explaining the work procedure. Here, it is assumed that the floor surface 11a of the dirt floor 11 is uneven, and the building unit 20 is installed on the floor surface 11a where the uneven surface is generated. Each building unit 20 is manufactured in advance at a manufacturing factory and is transported to a building by a truck or the like.

  When installing the building unit 20 on the dirt floor 11, first, as shown in FIG. 9A, the support members 13 to 16 are respectively installed at the locations where the pillars 21 of the building units 20 are placed on the dirt floor 11. Work to do. In this operation, the first fixing portions 35 of the support members 13 to 16 are fixed to the dirt floor 11 with the anchor bolts 41.

  Since the floor 11a of the dirt floor 11 is uneven as described above, in this case, due to the unevenness, the installation height between the support members 13 to 16 installed on the floor 11a. May be different from each other. For example, in FIG. 9A, the support member 13 is disposed lower than the support member 14 due to unevenness, and the upper surface of the support member 13 (second fixing portion 36) is the upper surface of the support member 14 (second fixing portion 65). Is in a lower position.

  Therefore, as the next work, by adjusting the height positions of the second fixing portions 36, 65, 71, 76 relative to the first fixing portion 35 in the supporting members 13-16, the supporting members 13-16 (second fixing members) are adjusted. The top surface height of the portions 36, 65, 71, 76) is adjusted to the same height (specifically, substantially the same height). As described above, the height position adjustment of the second fixing portions 36, 65, 71, 76 with respect to the first fixing portion 35 is performed by attaching the operation jig 63 to the jig hole 61 of the connecting shaft portion 37 and operating the second fixing portions 36, 65, 71, 76. This is performed by rotating the connecting shaft portion 37 with respect to the fixed portions 35 and 36 using the jig 63. For example, in FIG. 9B, the height of the upper surface of the support member 14 is reduced by lowering the height position of the second fixing portion 65 with respect to the first fixing portion 35 in the support member 14 disposed higher than the support member 13. Is adjusted to the height of the upper surface of the support member 13.

  Next, as shown in FIG.9 (c), the work which installs the building unit 20 is performed by mounting each pillar 21 of the building unit 20 on the supporting members 13-16. After the building unit 20 is installed (after installation), the installation height of each column 21 is adjusted by adjusting the height positions of the second fixing portions 36, 65, 71, 76 relative to the first fixing portion 35 in the support members 13-16. Work to adjust the height to the same height. That is, the level adjustment of the building unit 20 is performed. Thereby, the building unit 20 is installed in a horizontal state on the floor surface 11a where unevenness occurs.

  In the above height position adjustment, it is desirable to perform the adjustment work while supporting the load of the building unit 20 with a jack device or the like. If it does so, it will become possible to rotate the connection shaft part 37 comparatively easily in the case of adjustment work. Further, after the adjustment work is completed, the operation jig 63 is removed from the jig hole 61 of the connecting shaft portion 37.

  Next, as shown in FIG. 9 (d), the column base plate 48 of each column 21 of the building unit 20 is attached to the second fixing portions 36, 65, 71, 76 of the support members 13-16 by bolts 51 and nuts 52. Do the fixing work. Thereby, the installation work on the floor 11 of the building unit 20 is completed.

  In the above work procedure, the level of the building unit 20 is adjusted before fixing the pillars 21 to the second fixing portions 36, 65, 71, 76 of the support members 13-16. The level of the building unit 20 may be adjusted after being fixed to the second fixing portions 36, 65, 71, 76.

  As mentioned above, according to the structure of this embodiment explained in full detail, the following outstanding effects are acquired.

  As above-mentioned, the installation height of each pillar 21 of the building unit 20 is adjusted by adjusting the height position of the 2nd fixing | fixed part 36,65,71,76 with respect to the 1st fixing | fixed part 35 in the supporting members 13-16. The level of the building unit 20 was adjusted accordingly. In this case, the level adjustment of the building unit 20 can be performed relatively easily because it is not necessary to perform the troublesome work of interposing a spacer between the dirt floor 11 and the support members 13 to 16 in the level adjustment. .

  Since the connecting shaft portion 37 is rotatably connected to the fixing portions 35 and 36, the connecting shaft portion 37 is fixed to the fixing portions 35 and 36 with the rotation directions of the fixing portions 35 and 36 being unchanged. Can be rotated. Thereby, in a state where the first fixing portion 35 is fixed to the dirt floor 11 and the column 21 of the building unit 20 is fixed to the second fixing portion 36, that is, in a state where the building unit 20 is installed on the support members 13 to 16. The level of the building unit 20 can be adjusted. Therefore, for example, the level adjustment can be performed while checking the actual level of the building unit 20, and as a result, the level adjustment can be performed with high accuracy.

  In the conventional method of adjusting the level of the building unit 20 by interposing a spacer between the dirt floor 11 and the support members 13 to 16, the level is set only before the building unit 20 is installed on the support members 13 to 16. Since adjustment cannot be performed, if it is found that the building unit 20 is tilted after the building unit 20 is installed, the building unit 20 is lifted from the support members 13 to 16, etc. The work of redoing the spacer with the spacer 16 has occurred. In that respect, in the above-described level adjustment method using the support members 13 to 16, the level can be adjusted even after the unit is installed. Therefore, the level can be obtained without performing troublesome work such as lifting the building unit 20 from above the support members 13 to 16. Adjustments can be made.

  Of the male screw portions 56 and 57 of the connecting shaft portion 37, the male screw portion 56 screwed into the first fixing portion 35 is a normal screw, and the male screw portion 57 screwed into the second fixing portion 36 is reversed. Since it is a screw, when the connecting shaft portion 37 is rotated to one side in the direction around the axis with respect to the fixed portions 35 and 36, the fixed portions 35 and 36 are moved closer to each other in the vertical direction with respect to the connecting shaft portion 37. When the connecting shaft portion 37 is rotated to the other side in the direction around the axis with respect to the fixing portions 35 and 36, the fixing portions 35 and 36 are moved to the connecting shaft portion 37 on the side away from each other in the vertical direction. It is displaced with respect to it. In this case, since the relative displacement amount of each of the fixing portions 35 and 36 with respect to the rotation operation amount of the connecting shaft portion 37 can be increased, the height position of the second fixing portion 36 with respect to the first fixing portion 35 can be easily adjusted. can do.

  The connecting shaft portion 37 is provided with a jig hole 61 for detachably attaching an operation jig 63 (operation portion) used when rotating the shaft portion 37. In this case, when the connecting shaft portion 37 is rotated, the operation jig 63 can be attached to the connecting shaft portion 37, and in other cases, the operation jig 63 can be detached from the connecting shaft portion 37. . As a result, it is possible to avoid a situation in which the operator or the like unintentionally contacts the operation portion and the connecting shaft portion 37 rotates, thereby changing the height position of the column 21.

  Support members 14 to 16 are provided in the column aggregate portions 31 to 33 where the columns 21 of the plurality of building units 20 are aggregated. In the support members 14 to 16, the second fixing portions 65, 71, and 76 are arranged as the column aggregate portions 31 to 33. Are provided so as to straddle the lower end of each column 21, and the lower end of each column 21 is fixed to the second fixing portions 65, 71, 76. In this case, since the height position adjustment of the columns 21 constituting the column assembly portions 31 to 33 can be performed collectively, the man-hours can be reduced when the level adjustment of the building unit 20 is performed.

  Since the support members 14 to 16 provided in the column aggregate portions 31 to 33 and the support member 13 provided in one column 21 that does not constitute the column aggregate portion have the same configuration of the first fixing portion 35, each of these supports The members can be shared among the members 13-16. Therefore, effects such as cost reduction can be obtained. In addition, since the positioning of the anchor bolt 41 when the first fixing portion 35 is fixed to the floor 11 with the anchor bolt 41 can be made common among the support members 13 to 16, the positioning operation is facilitated. can do.

  In addition, since the support members 14 to 16 provided in the column aggregate portions 31 to 33 and the support member 13 that does not constitute the column aggregate portions have the same configuration as the connecting shaft portion 37, Therefore, it is possible to further share the members, and it is possible to further obtain effects such as cost reduction.

  In addition, since the first fixing portion 35 and the connecting shaft portion 37 are made common in each of the support members 13 to 16, the second fixing portions 36, 65, 71, and 76 of the support members 13 to 16 are replaced with another support member 13. If the second fixing portions 36, 65, 71, and 76 are replaced with each other, the forms of the support members 13 to 16 can be changed. For example, if the second fixing portion 36 of the support member 13 is replaced with the second fixing portion 65 (of the support member 14), the form can be changed from the support member 13 to the support member 14. Therefore, in this case, when the type of the supporting members 13 to 16 to be used is changed due to the layout change of the building 10 or the like, it is possible to cope with it by changing the form of the supporting members 13 to 16 accordingly. This is advantageous in that respect. In addition, it is assumed that the building 10 constructed as a filling place in the building may be relocated within the building, and in that case, the layout may be changed upon the relocation. Therefore, the above configuration is advantageous even in view of this point.

  The present invention is not limited to the above embodiment, and may be implemented as follows, for example.

  (1) In the above embodiment, the connecting shaft portion 37 of the support members 13 to 16 is provided with the male screw portions 56 and 57 that are screwed into the first fixing portion 35 and the second fixing portions 36, 65, 71, and 76. Any one of these male screw portions 56 and 57 may not be provided. For example, it is conceivable that only the male screw portion 56 is provided in the connecting shaft portion 37 of the support members 13 to 16 without providing the screw portion 57. In this case, the female screw portion 53a is not provided in the bearing portion 46 of the second fixing portion 36, 65, 71, 76. Even in such a configuration, the connecting shaft portion 37 can be displaced in the vertical direction (axial direction) with respect to the first fixing portion 35 by rotating the connecting shaft portion 37 with respect to the first fixing portion 35. The height positions of the second fixing portions 36, 65, 71, 76 with respect to the first fixing portion 35 can be adjusted.

  In the above configuration, the connecting shaft portion 37 is inserted into the shaft hole 53 of the bearing portion 46 of the second fixing portion 36, 65, 71, 76, and the second fixing portion 36, 65, 71, 76 is inserted in the inserted state. Can be rotated. Therefore, when adjusting the height position of the second fixing portions 36, 65, 71, 76 with respect to the first fixing portion 35 by rotating the connecting shaft portion 37 with respect to the first fixing portion 35, the connecting shaft portion 37. Can be rotated with respect to the second fixing portions 36, 65, 71, 76. Therefore, also in this case, when the height position is adjusted, the connecting shaft portion 37 is fixed to each of the fixing portions 35 with the rotation directions of the first fixing portion 35 and the second fixing portions 36, 65, 71, 76 being unchanged. , 36 can be rotated. Therefore, also in this case, the first fixing part 35 is fixed to the floor 11 and the column 21 of the building unit 20 is fixed to the second fixing parts 36, 65, 71, 76, that is, the building unit 20 is supported. The level of the building unit 20 can be adjusted while being installed on the member 13.

  (2) When the connection shaft portion 37 of the support members 13 to 16 described in the above (1) is configured not to provide the screw portion 57 but only the male screw portion 56, the connection shaft portion 37 is the second one. You may make it fix to the bearing part 46 of the fixing | fixed part 36,65,71,76 by welding etc. FIG. That is, the connecting shaft portion 37 may be fixed to the second fixing portions 36, 65, 71, and 76 in a non-rotatable state. Even in such a configuration, the connecting shaft portion 37 (and the second fixing portions 36, 65, 71, 76) is rotated with respect to the first fixing portion 35, whereby the connecting shaft portion 37 is moved with respect to the first fixing portion 35. Therefore, the height positions of the second fixing portions 36, 65, 71, and 76 with respect to the first fixing portion 35 can be adjusted.

  However, in this case, when the height position is adjusted, the second fixing portions 36, 65, 71, and 76 rotate together with the connecting shaft portion 37, so that the column 21 of the building unit 20 is installed on the support member 13. Thus, it becomes impossible to adjust the level of the building unit 20. Therefore, in view of this point, it is desirable that the connecting shaft portion 37 be rotatable with respect to the second fixing portions 36, 65, 71, 76 as in the configuration described in (1) above.

  (3) In the above-described embodiment, the column aggregate portions 31 to 33 are configured to commonly support the columns 21 constituting the column aggregate portions 31 to 33 by the support members 14 to 16. Also in 33, it is good also as a structure which provides a support member separately for every pillar 21 which comprises the column aggregate parts 31-33, and supports the one pillar 21 by these support members. In this case, a support member is individually provided for each column 21 of the building unit 20 constituting the building 10. Therefore, the support member can be shared in the building 10.

  In such a configuration, when installing the building unit 20, first, a supporting member is fixed to each column 21 of the building unit 20 with a bolt, and then the building unit 20 to which the supporting member is fixed is installed in the soil. It can be considered to be installed on the floor 11. At this time, anchor bolts are embedded in the floor 11 in advance, and when the building unit 20 is installed, the building unit 20 is placed on the floor 11 while the anchor bolts are inserted through the insertion holes of the first fixing portions of the support members. It is possible to install it in

  (4) In the said embodiment, although the structure of the connection shaft part 37 was made the same between each support member 13-16, you may vary the structure of the connection shaft part 37 between each support member 13-16. . For example, it is conceivable to increase the strength of the support members 13 to 16 having a larger number of columns 21 by increasing the diameter of the connecting shaft portion 37.

  Moreover, you may vary the structure of the 1st fixing | fixed part 35 between each support members 13-16. For example, it is conceivable that the support members 13 to 16 having a larger number of support columns 21 increase the area of the fixing plate 45 of the first fixing portion 35 to obtain a stable support state.

  (5) In the above embodiment, the present invention is applied to the building 10 used as a filling station. However, the present invention may be applied to a building used for other purposes such as an office or a warehouse. In addition, the building 10 is not necessarily built in the building (and thus indoors), and may be built outdoors. For example, it is conceivable to construct the main building 10 in a work place or the like whose floor is made of concrete outdoors.
