  As shown in FIG. 1, a gap S of about 10 mm to 20 mm is generated between the adjacent building units 1 and 1 as shown in FIG. The position adjusting device 2 is mainly configured by a pair of fixing members 3A and 3B disposed in the gap S and a distance adjusting means for adjusting the distance between the fixing members 3A and 3B.

  The fixing body 3 </ b> A (3 </ b> B) includes a plate-like plate body 31 disposed between the floor beams 12 and 12 of the adjacent building units 1 and 1, and a plurality of pin portions 32 provided at intervals below the plate body 31. , 32 and mooring holes 33, 33 as mooring portions provided on the upper portion of the plate body 31 that protrudes upward between the floor beams 12, 12.

  Since the configuration of the pair of fixing members 3A and 3B is substantially the same, in the following description, one of the symbols may be used as a representative. The plate body 31 of the fixing body 3A is formed of a rectangular steel plate or the like as shown in FIGS. The plate thickness of the plate body 31 can be, for example, about 4 mm to 6 mm.

  Pin holes 321 and 321 for mounting the pin portions 32 and 32 are drilled in the lower portion of the plate body 31. Since the pin parts 32 and 32 are provided at intervals in the longitudinal direction of the floor beam 12, the pin holes 321 and 321 are also provided accordingly.

Therefore, by shifting the heights of the mooring holes 33 and 33 aligned in the width direction. A decrease in rigidity can be suppressed.

  The pin portion 32 whose end is inserted into the pin hole 321 is formed in a columnar shape longer than the plate thickness of the plate body 31. By making the length of the pin portion 32 shorter than the gap S, the lower portions of the fixing bodies 3A and 3B can be inserted into the gap S from above.

  The first spacer 5A (5B) is laminated on the surface of the plate body 31 from which the pin portions 32, 32 are projected. The first spacer 5 </ b> A can be formed of a rectangular steel plate having the same width as the plate body 31.

  The plate thickness of the first spacer 5A can be adjusted by the length by which the pin portion 32 protrudes from the plate body 31 and the amount inserted into the side hole 124A of the floor beam 12.

  The insertion hole 51 for passing the pin portion 32 of the first spacer 5 </ b> A can have an inner diameter that is slightly larger than the diameter of the pin portion 32. The first spacer 5A is joined to the plate body 31 by welding.

  On the other hand, the second spacers 61A and 62A are stacked on the surface opposite to the surface from which the pin portions 32 and 32 of the plate body 31 protrude. Here, what is stacked around the mooring hole 33 at the lower position is referred to as the second spacer 61A, and what is stacked around the mooring hole 33 at the higher position is referred to as the second spacer 62A.

  Hole portions 611 and 621 having the same size as the anchoring holes 33 and 33 are formed in the second spacers 61A and 62A, respectively. Therefore, the positions of the holes 611 and 621 are aligned with the positions of the mooring holes 33 and 33, and the second spacers 61A and 62A are joined to the plate body 31 by welding.

  In this embodiment, a lever block (registered trademark) is used as the distance adjusting means. As shown in FIG. 1, the lever block 4 is mainly composed of hook portions 41A and 41B at both ends, a chain portion 42 that connects the hook portions 41A and 41B, and a lever portion 43 that adjusts the effective length of the chain portion 42. Configured.

  The hook portions 41A and 41B are hooked in the anchoring holes 33 and 33 of the fixing members 3A and 3B, respectively. When the lever portion 43 is operated in this state, the length (effective length) of the chain portion 42 between the hook portions 41A and 41B changes, and the distance between the fixing members 3A and 3B is adjusted.

  Next, a method for adjusting the position of the building units 1 and 1 using the position adjusting device 2 of the present embodiment will be described, and the operation thereof will be described.

  FIG. 1 shows a state where the positions of building units 1 and 1 installed adjacent to each other with a gap S therebetween are relatively shifted in the longitudinal direction of the floor beam 12 for the sake of explanation. Yes.

  In order to correct the relative displacement in the longitudinal direction of the floor beam 12, the position adjusting device 2 of the present embodiment is installed. First, the fixing body 3A is attached from above the gap S to the floor beam 12 on the back side in FIG.

  Since side holes 124A and 124A are perforated in the floor beam 12 at intervals in the longitudinal direction, the tips of the pin portions 32 and 32 protruding from the first spacer 5A with respect to the side holes 124A and 124A. Insert.

  FIG. 5 is a cross-sectional view showing a state where the fixing body 3A is attached to the side surface of the floor beam 12 on the left side. In this figure, in order to emphasize the state where the pin portion 32 is inserted into the side hole 124A, the tip end of the pin portion 32 protrudes from the web 123, but the pin portion 32 does not necessarily have to protrude.

  As shown in FIG. 5, there is an attachment error in the floor board 17 attached to the floor beam 12 in the factory, and an edge may protrude above the gap S (see the left floor board 17). Even in such a case, the fixing body 3A in which the first spacers 5A are laminated can be brought into close contact with the side surface of the floor beam 12.

  On the other hand, the second spacer 61A (62A) is laminated on the upper part on the back side of the plate body 31, and when the upper part of the plate body 31 is inclined toward the building unit 1 side on the back side (right side in the figure), the second spacer 61A (62A) is inclined. The spacer 61 </ b> A (62 </ b> A) contacts the edge of the floor plate 17 to prevent further inclination.

  Even in this case, even if the edge is separated from the gap S due to the mounting error of the floor plate 17, it can be brought into contact with the floor plate 17 by increasing the thickness of the second spacer 61A (62A).

  On the other hand, the fixing body 3B is attached to the floor beam 12 on the near side in FIG. That is, the tips of the pin portions 32 and 32 protruding from the first spacer 5B are inserted into the side holes 124B and 124B that are drilled at intervals in the longitudinal direction.

  Here, as shown in the plan view of FIG. 6, the centers C of the plate bodies 31 and 31 of the fixing bodies 3A and 3B attached to the floor beams 12 and 12 can be made to coincide with each other.

  That is, by changing the plate thickness of the first spacers 5A and 5B, the second spacers 61A and 61B, and the second spacers 62A and 62B between the fixing members 3A and 3B, the plate main body 31 is located at a position other than the center of the gap S. , 31 can be arranged in a straight line.

  In this way, the lever block 4 is attached to the fixing members 3A and 3B attached to the side surfaces of the floor beams 12 and 12 facing each other with the gap S therebetween. The hook portion 41A of the lever block 4 may be hooked in any of the anchoring holes 33, 33 of the fixing body 3A.

  Further, the hook portion 41B of the lever block 4 may be hooked in any of the anchoring holes 33, 33 of the fixing body 3B. And in the state which hook part 41A, 41B was hooked in the mooring holes 33 and 33, the lever part 43 is operated and the distance between hook part 41A and 41B is shortened.

  At this time, the distance between the fixing members 3A and 3B is also reduced, and accordingly, the relative distance in the longitudinal direction of the floor beam 12 between the building units 1 and 1 is also reduced.

  The position adjusting device 2 and the position adjusting method of the building units 1 and 1 of the present embodiment configured as described above are the side holes 124A and 124A (124B) on the side surfaces of the floor beams 12 and 12 of the adjacent building units 1 and 1. , 124B), the pair of fixing members 3A, 3B are respectively attached by inserting the pin portions 32, 32 into the pin portions 32, 32. Then, the distance between the anchoring holes 33, 33 of the pair of fixing members 3A, 3B is adjusted by the lever block 4 serving as a distance adjusting means.

  If the fixing members 3A and 3B attached to the side surfaces of the floor beams 12 and 12 are used in this way, even if the upper surface (upper flange 121) of the floor beam 12 is covered by the floor plate 17, the floor beams 12 and 12 are used. The relative position adjustment in the longitudinal direction can be performed.

  Further, by fixing the fixing body 3A (3B) to the floor beam 12 via the plurality of pin portions 32, 32, the pin portion 32, the pin portion 32, via the plate body 31 from the hook portion 41A (41B) at the time of position adjustment. The force transmitted to 32 can be distributed as a load acting on the floor beam 12, and damage to the floor beam 12 can be prevented.

  Further, by laminating the first spacer 5A (5B) on the surface of the plate body 31 from which the pin portions 32, 32 are projected, the fixing body 3A (3B) is attached to the side surface of the floor beam 12 even if there is an attachment error in the floor plate 17. The pin portions 32 and 32 can be made difficult to come off from the side holes 124A and 124A (124B and 124B).

  In addition, the second spacers 61A and 62A (61B and 62B) are stacked on the surface opposite to the surface from which the pin portions 32 and 32 of the plate body 31 protrude, so that the second spacers 61A and 62A (61B and 62B) are formed. It is possible to prevent the fixing body 3 </ b> A (3 </ b> B) from coming off by contacting the floor plate 17 and preventing the plate body 31 from falling on the opposite side of the pin portions 32, 32.

  Further, by stacking the second spacers 61 </ b> A and 62 </ b> A (61 </ b> B and 62 </ b> B) around the mooring holes 33 and 33 drilled in the plate main body 31, the circumference of the mooring holes 33 and 33 can be reinforced.

  As a result, it becomes possible to resist the force acting from the hook portions 41A and 41B around the mooring holes 33 and 33, so that the plate body 31 can be made thin.
