Here, a method of constructing the building structure shown in FIG. 1 will be described. This construction method, in order, pillar installation process,
Jig fixing process, spacer fixing process, beam member setting process,
Wall forming step. In the above pillar installation step, pillars 1 and 1 are installed on a base (not shown). Next, in a jig fixing step, the fixing jig 50 is
Fix each one. At this time, the first fastener 70 may be fastened by inserting a screwdriver or other fastening tool from the through window 54 provided on the inner side surface 54 of the fixing jig 50 (not shown). For example, an impact driver is inserted into the fixing jig 50 through the through
The nut can be turned. On the other hand, two structural parts 3 and 3 are prepared, and a spacer 51 is disposed between the two structural parts 3 and 3 in the spacer fixing step.
The two structural parts 3 and 3 and the spacer 51 are integrated with the fastener 72. The two structural parts 3, 3 integrated above are
In the above beam member installation step, the fixing jig 50 passed between the pillars 1 and 1 and placed on the pillars 1 and 1 is sandwiched between the two structural parts 3 and 3, and is fixed by the second fastener 71 described above. The fixing jig 50 and the structural parts 3 and 3 are fixed. Thereby, the beam member 2 is formed between the columns 1 and 1. Finally, a wall member 6 is provided between the columns 1 and 1 and the beam member 2 in a wall forming step.

In the above, a spacer fixing step is provided to integrate the two structural parts 3, 3 and the spacer 51 before fixing them to the columns 1, 1. In addition, without providing such a spacer fixing step, the fixing jig 50 is provided in the beam member setting step.
On the other hand, it is also possible to implement the structure parts 3 and 3 before being integrated, and to implement the attachment of the spacer 51 at this time. In addition, in the jig fixing step, the beam member 2 is completed by fixing the structural parts 2 and 2 and the fixing jig 50 instead of providing the fixing jig 50 on the column 1 and then installing the beam member. In the process, the fixing jig 50 may be fixed to the columns 1 and 1 together with the structural portions 2 and 2.

In the above construction method, the wall forming step is performed after (finally) the beam member setting step. However, the wall forming step is performed before the beam member setting step. Is also feasible. That is, the wall member 6 is formed between the columns 1 and 1 before the beam member 2. Then, the structural parts 3 and 3 integrated by the spacer are
And the beam member 2 is formed between the columns 1 and 1 through the first fastener 70. In this case, since the wall member 6 is already provided between the columns 1 and 1 before the beam member 2 is formed, the structural parts 3 and 3 are inserted between the columns 1 and 1 from above and fixed. I do.

A fixing jig 50 for making the above-mentioned fixing work easier when the beam member 2 is provided after disposing the wall member 6 will be described with reference to FIG. This fixing jig 5

The fixing jig 50 is previously fixed to the columns 1 and 1 (in the same manner as the fixing jig 50 shown in FIG. 1B) in the above jig fixing step. Then, in the spacer fixing step, the structural parts 3 and 3 and the spacer 51 are fixed and inserted into the uppermost part of the fixing jig 50 (of the second fasteners 71... 71 inserted in the beam member setting step). The second fastener 71 is provided in the structural parts 3 and 3 in advance. Then, in the beam member installation step, as described above, the structural parts 3, 3 are dropped from above to below between the columns 1, 1. At this time, the second fastener 71 already provided on the structural parts 3 and 3 in the spacer fixing step
By guiding the fixing jigs 50, 50 fixed to 1 to the above notches 55, 55, the deepest portions 56, 56 of the notches 55, 55 have already been provided in the structural parts 3, 3. The second fastener 71 is placed. Thus, positioning (temporary fastening) between the columns 1 and 1 at a predetermined position can be performed, and the remaining second fastener 71 can be accurately and easily fixed. In the fixing jig 50 of this embodiment,
The configuration other than the formation of the cut portions 55, 55 is the same as that of the embodiment shown in FIG. In a normal construction method, a wall is formed after columns and beams (beam members) are provided. However, by adopting the above-described method, a wall panel (wall member) is arranged between columns before the beams. Also in the construction method, the installation of the beams (structures 3 and 3) does not become difficult due to the presence of the wall panel.

In the embodiment shown in FIG. 1, a beam member 2 is provided at the uppermost portion between the columns 1 and 1 (FIG. 1).
(A)). That is, the upper portion of the beam member 2 and the upper portions of the columns 1 and 1 are made to have the same height. In addition, as shown in FIG.
The present invention can also be implemented by providing the beam member 2 at a position lower than the uppermost portion shown in FIG. The structure shown in FIG. 2 is the same as that of the embodiment of FIG. 1 except for the vertical position of the beam member 2 with respect to the columns 1 and 1, and may be substantially considered as a perspective view of the building structure shown in FIG. . In FIG. 2, the wall member 6 is omitted.

In the embodiment shown in FIGS. 1 and 2 described above, the spacer 51 is provided between the hollow part 4, that is, between the structural parts 3 and 3. However, as shown in FIG. It is possible to carry out without. When the spacer 51 is not provided, the fixing jig 50 plays the role of the spacer 51. In the embodiment shown in FIGS. 1 and 2, the spacers 51 are adjacent to the fixing jigs 50 between the structural parts 3.
In addition, the spacers 51, 51 can be implemented between the structural parts 3, 3 so as not to be adjacent to the fixed axial directions 50, 50 (not shown). Further, three or more spacers 51 are provided, and a part of them is arranged in the same manner as shown in FIG. 1 and another part is provided at another position between the structural parts 3 and 3. It is also possible (not shown). In the embodiment shown in FIGS. 1 and 2 described above, the second fasteners 71... 71 are inserted through all the sub through holes 53. On the contrary,
In the embodiment shown in FIG. 3, through holes 30.
The second fasteners 71... 71 do not pass through all of the 0 and the sub through holes 53.
Through-holes 30... 30 and sub-through-holes 53.
There is also. If sufficient fixing strength can be secured, reducing the number of parts in this way enables reduction of cost and labor, and further facilitates the work of fixing other fasteners,
It is effective.

In the embodiment of FIG. 1, it has been described that one beam member 2 is provided for one column 1 in order to make it easy to understand the state of attachment of the beam member 2 to the column 1. Actually, a beam 2a and a girder 2b for one pillar 1
In many cases, at least two beam members 2 are provided.
Such a case will be described with reference to FIG. FIG.
(A) is a partially cut-away schematic cross-sectional view showing one pillar 1 and its periphery, and FIG. 5 (B) is a partially cut-out schematic vertical sectional view thereof. As shown in FIG. 5, when the beam 2 a and the beam 2 b are provided at the same height in the vertical direction with respect to the column 1, the first fasteners 70 do not collide with each other in the column 1. You need to do that. That is, as shown in FIG. 1 (C), the fixing jig 50 is provided with a plurality of through holes 52... 2b, the first fastener 7 is inserted into all the through holes 52.
If the first fasteners 70 of the beam 2a and the beam 2b are to be inserted through the through holes 52 having the same height, the first fasteners 70 of both the beam 2a and the spar 2b. 70 interfere with each other, which hinders the attachment of the fixing jigs 50 on both the beam 2a and the beam 2b. Therefore, as described above, in the two fixing jigs 50, the first fastener 70 is inserted into every other through hole 52. At this time, for example, as for the fixing jig 50 provided on the beam 2a, the first fastener 70 is inserted into the odd-numbered through holes 52... 52 from among the through holes 52. The provided fixing jig 50 has through holes 52.
Of these, the first fastener 70 may be inserted into the even-numbered through holes 52. In this manner, the first fasteners 70... 70 are attached to the fixing jigs 50 of the beam 2 a and the beam 2 b so that the attachment positions of the first fasteners 70 do not overlap each other so as to avoid the attachment positions. (Figure 5
(B)).

When two types of beam members 2 of the beam 2a and the spar 2b are provided, the end of each of the beam members 2 is fixed to the column 1 as described above. In addition, as shown in FIG. 4B, one of the beam members 2 of the beam 2a and the beam 2b is
It is also possible to implement the present invention directly on the other beam member 2 without using the pillar 1. That is, the end faces 3a, 3a of the structural parts 3, 3 of the other beam member 2 are fixed so as to be in contact with the front surface or the rear surface of the one structural part 3. As a result, as shown in FIG. 4B, the two beam members 2 have a substantially T-shape in plan view. In this embodiment, the first fastener 70 passed through the fixing jig 50 of the beam 2b is passed through the structural portions 3 and 3 of the beam 2a to fix the beam 2a and the beam 2b. In addition, in order to secure necessary strength, a spacer 51 is provided at a position of the beam 2a where the first fastener 70 is passed, and the first fastener 70 penetrates the spacer 51. .

In each of the above embodiments,
Although the fixing jig 50 is provided, as shown in FIG. 6 (A), it is also possible to provide only the spacer 51 and to implement without providing the fixing jig 50. In this case, the structural parts 3, 3
