By changing the distance between the square column and the beam, you can align the square column and the beam. Therefore, interference between the column joint and the beam end is suppressed, and as a result, the column joint and the beam end can be easily connected without applying a large force to the column or beam using a hammer or the like. The position can be adjusted and the burden on the worker can be reduced.

The beam-to-column joining method of the present invention is used to connect a beam to a beam by constructing a beam between a pair of square columns that are erected at a predetermined interval. Further, the position adjustment jig of the present invention is used to align the joint portion (first construction member) provided on the side surface of the square column and the end of the beam (second construction member).

<<Column-beam joint structure>>
FIGS. 1 and 2 are diagrams showing the basic structure of a beam-column connection. FIG. 1 shows a perspective view of the column PL and the beam BM separated. FIG. 2 shows a plan cross-sectional view of a state in which the pillar PL and the beam BM are joined. As shown in FIGS. 1 and 2, in the end plate type column-beam joint structure, the column plate PL1 fixed to the side surface of the column PL and the end plate BM1 fixed to the end of the beam BM are connected by high-strength bolts. Bolted together by HB. Thereby, the column PL and the beam BM are joined. Although only one pillar PL is illustrated in FIGS. 1 and 2, a pair of pillars PL are erected at a predetermined interval, and a beam BM is constructed between the pair of pillars PL. Joined.

The pillar PL mainly includes a pillar main body PL3 which is a square pillar made of steel, and a pillar plate PL1 welded to the side surface of the pillar main body PL3. The pillar plate PL1 is a joint portion to which the beam BM is joined, and is fixed to the pillar body PL3 by welding. The pillar plate PL1 is a steel plate, and has a screw hole PL2 that can be screwed into the high-strength bolt HB.

The beam BM is an H-shaped steel and has an upper flange BM4, a lower flange BM5, and a web BM3 that vertically connects the upper flange BM4 and the lower flange BM5. A jig fixing hole BM6 for fixing a position adjustment jig 10, which will be described later, is formed in the upper flange BM4. In FIG. 1, the jig fixing hole BM6 is formed in the upper flange BM4, but may be further formed in the lower flange BM5. The position adjustment jig 10 will be described later. The upper flange BM4 and the lower flange BM5 correspond to flange parts.
An end plate BM1 is fixed to the end of the beam BM by welding. The end plate BM1 is a steel plate, and has a through hole BM2 through which the high-strength bolt HB can be inserted.

In FIG. 1, a total of six screw holes PL2, three on each side, are formed in the pillar plate PL1, and six through holes BM2 are formed in the end plate BM1. It is not limited to this. Eight or more screw holes PL2 and through holes BM2 may be formed.

<<Position adjustment jig 10>>
Next, the position adjustment jig 10 used when joining the columns and beams will be explained. 3 and 4 are diagrams showing the appearance of the position adjustment jig 10. That is, FIG. 3 is a perspective view of the position adjustment jig 10, and FIG. 4 is a plan view of the position adjustment jig 10.

As shown in FIGS. 3 and 4, the position adjustment jig 10 mainly includes a first distance changing member 11 and a second distance changing member 14.

The first distance changing member 11 is fixed to the beam BM and plays a role of changing the distance between the column PL and the beam BM in the longitudinal direction of the beam BM (corresponding to the first direction).
The first distance changing member 11 mainly includes a first fixed member 12 attached to the upper flange BM4 of the beam BM, and a first movable member 13 displaced with respect to the first fixed member 12. It has as a configuration.

The first fixing member 12 is a long body having a substantially L-shaped cross section, and includes a first fixing plate 12a joined to the upper flange BM4 of the beam BM, and a first fixing plate 12a. It is a steel angle member having a first upright plate 12b extending vertically.
Three fixing holes 12d are formed in the first fixing plate 12a. The fixing hole 12d passes through the first fixing plate 12a. The first fixing plate 12a is fixed to the upper flange BM4 of the beam BM by inserting a jig fixing bolt BT, as will be described later with reference to FIG. Although three fixing holes 12d are formed in FIGS. 3 and 4, the number of fixing holes 12d is not limited to three. By changing the fixing hole 12d through which the jig fixing bolt BT is inserted, the attachment position of the position adjustment jig 10 with respect to the beam BM can be changed.

Two movable member insertion holes 12e are formed in the first upright plate 12b. The movable member insertion hole 12e passes through the first upright plate 12b. As shown in FIG. 4, a nut 12f is fixed by welding to a position corresponding to the movable member insertion hole 12e of the first upright plate 12b. The nut 12f has a threaded hole on its inner periphery, and is screwed into a position adjustment screw 13a of the first movable member 13, which will be described later. Here, the first movable member 13 is inserted into either of the two movable member insertion holes 12e formed. Further, the number of movable member insertion holes 12e is not limited to two. Of course, three or more movable member insertion holes 12e may be formed. The movable member insertion hole 12e corresponds to a first insertion hole.

The first movable member 13 has an elongated shape and includes a position adjustment screw 13a and a rotation operation part 13c. The first movable member 13 is inserted into the movable member insertion hole 12e and screwed into the nut 12f. The first movable member 13 is displaced with respect to the first upright plate 12b when the rotation operation section 13c is rotated. Then, as will be described later, by rotating the rotary operation part 13c with the tip end 13b in contact with the side surface of the column PL, the column PL is pressed in a direction away from the beam BM, and the column PL is moved away from the beam BM. It can be displaced away from the BM. In other words, by rotating the first movable member 13, the distance between the column PL and the beam BM in the longitudinal direction of the beam BM can be changed.

The second distance changing member 14 is connected and fixed to the end of the first distance changing member 11 by welding. The second distance changing member 14 plays a role of changing the distance between the column PL and the beam BM in the transverse direction (corresponding to the second direction) of the beam BM.
The second distance changing member 14 includes a second fixed member 15 fixed to the end of the first distance changing member 11, and a second movable member 16 that is displaced with respect to the second fixed member 15. The main structure is

The second fixing member 15 is a long body having a substantially L-shaped cross section, and includes a second fixing plate 115a having a horizontal surface and a second upright plate 15b extending perpendicularly from the second fixing plate 15a. It is a steel angle material having.

Two movable member insertion holes 15e are formed in the second upright plate 15b. The movable member insertion hole 15e passes through the second upright plate 15b. As shown in FIG. 4, a nut 15f is fixed by welding to a position corresponding to the movable member insertion hole 15e of the second upright plate 15b. The nut 15f has a threaded hole on its inner periphery, and is screwed into a position adjustment screw 16a of the second movable member 16, which will be described later. The number of movable member insertion holes 15e is not limited to two. Of course, three or more movable member insertion holes 15e may be formed. The movable member insertion hole 15e corresponds to a second insertion hole.

The second movable member 16 has an elongated shape and includes a position adjustment screw 16a and a rotation operation part 16c. The second movable member 16 is inserted into the movable member insertion hole 15e and screwed into the nut 15f. The second movable member 16 is displaced with respect to the second upright plate 15b when the rotation operation section 16c is rotated. Then, as will be described later, the beam BM can be displaced in the lateral direction of the beam BM by rotating the rotary operation section 13c with the tip portion 16b in contact with the side surface of the column PL. In other words, by operating the second movable member 16, the distance between the column PL and the beam BM in the transverse direction of the beam BM can be changed.

<<Column beam connection method>>
Next, the column-beam joining method will be explained.
FIG. 5 shows the procedure for joining columns and beams at a construction site. As shown in FIG. 5, first, using a lifting device such as a crane truck, the beam BM is suspended between a pair of pillars PL erected at a predetermined interval (step S10, arrangement step).

Next, one end of the beam BM is temporarily fixed to one of the pair of columns PL (step S12, first temporary fixing step). More specifically, the pillar plate PL1 provided on the side surface of one pillar PL and the end plate BM1 joined to one end of the beam BM are bolted together using temporary bolts.

Subsequently, the column plate PL1 (joint portion) of the other column PL and the other end plate BM1 (end portion) of the beam BM are aligned (step S14, alignment step). Here, the alignment process will be described in detail with reference to FIGS. 6 to 10B.

FIG. 6 shows the positional relationship between the pillar PL and the beam BM before alignment. As shown in FIG. 6, before the alignment is performed, the pillar plate PL1 and the end plate BM1 are not positioned to directly face each other. Therefore, it is not possible to temporarily fix the column plate PL1 and the end plate BM1 by joining them with temporary bolts. Therefore, it is necessary to align the pillar plate PL1 and the end plate BM1.

FIG. 7 shows a state in which the position adjustment jig 10 is attached to the upper flange BM4 of the beam BM.
As shown in FIG. 7, the position adjustment jig 10 is fixed to the upper flange BM4 on the longitudinal end side of the beam BM (jig fixing step). The position adjustment jig 10 is fixed to one side (the right side in FIG. 7) of the beam BM in the transverse direction using a jig fixing bolt BT. Thereby, the position adjustment jig 10 can be attached to the beam BM without interference between the pillar PL and the second distance changing member 14.

Next, the operator brings the tip end 13b of the first movable member 13 into contact with the side surface of the pillar PL on which the pillar plate PL1 is provided. Next, the operator operates the first movable member 13 to change the distance between the column PL and the beam BM in the longitudinal direction of the beam BM (first distance changing step). Specifically, the operator can displace the first movable member 13 in the longitudinal direction of the beam BM by rotating the first movable member 13. Thereby, the pillar PL is displaced in the direction away from the end of the beam BM (the direction indicated by the arrow A1 in FIG. 7), and the pillar plate PL1 and the end plate BM1 can be positioned so as not to interfere with each other. Therefore, the distance between the pair of columns PL increases, the beam BM is interposed between the columns PL, and it becomes possible to align the columns PL and the beam BM.

Next, as shown in FIG. 8, the worker moves the tip 16b of the second movable member 16 to the side surface of the column PL that is perpendicular to the side surface on which the column plate PL1 is provided (the side surface shown on the right side of FIG. 8). ). Next, the operator displaces the second movable member 16 to change the distance between the column PL and the beam BM in the transverse direction of the beam BM (second distance changing step). Specifically, the operator displaces the second movable member 16 in the lateral direction of the beam BM by rotating the second movable member 16. Thereby, the pillar plate PL1 and the end plate BM1 can be positioned so as to directly face each other.

FIG. 9 shows a state in which the column PL and the beam BM have been aligned and the column plate PL1 and the end plate BM1 are directly facing each other. By arranging the pillar plate PL1 and the end plate BM1 to face each other in this way, it becomes possible to temporarily fix the pillar plate PL1 and the end plate BM1 by joining them with temporary bolts.

Next, vertical positioning of the pillar PL and the beam BM will be explained.
10A and 10B show a state in which the column PL and the beam BM are aligned in the vertical direction. That is, FIG. 10A is a front view of the pillar PL and beam BM, and FIG. 10B is a plan cross-sectional view.

As shown in FIGS. 10A and 10B, the position adjustment jig 10 is attached to the upper surface of the upper flange BM4 on one side of the beam BM in the lateral direction (the right side in FIGS. 10A and 10B). As described above, the position adjustment jig 10 is bolted to the upper flange BM4 of the beam BM using the jig fixing bolt BT.

By operating the crowbar BR, the worker applies force to the position adjustment jig 10 in the downward direction (in the direction indicated by the arrow A3 in FIG. 10A) with respect to the column plate PL1, thereby displacing the beam BM downward. I can do it. To explain in more detail, the worker first brings the tip end BR1 of the crowbar BR into contact with the lower surface of the upper flange bm4 of the beam bm joined to the column PL in a direction perpendicular to the beam BM. Next, the operator brings the extension part BR3 extending from the tip part BR1 into contact with the upper end surface 12c of the position adjustment jig 10. Subsequently, the operator operates the crowbar BR downward to displace the beam BM downward. Thereby, it becomes possible to align the pillar plate PL1 and the end plate BM1 so that they directly face each other.

As described above, after adjusting the position of the other end of the beam BM with respect to the other pillar PL, the other end of the beam BM is temporarily fixed with respect to the other pillar PL (see FIG. Step S16, second temporary fixing step). More specifically, the column plate PL1 joined to the side surface of the other column PL and the end plate BM1 fixed to the end of the beam BM are bolted together using temporary bolts.

Finally, the beam BM is permanently fixed to the pair of columns PL (step S18, main fixing step). More specifically, the beam BM is permanently fixed to the column PL by sequentially repeating the operations of removing the temporary bolts inserted through the end plate BM1 and the column plate PL1 and fastening the high-strength bolts HB.
By the above flow, the beam BM can be joined to the column PL.

Above, the column-beam joining method and the position adjustment jig 10 used when joining the columns and beams according to an embodiment of the present invention have been described. This is merely an example and is not intended to limit the invention.
In the embodiment described above, the position adjustment jig 10 has been described as being fixed to the beam BM in the alignment process, but the present invention is not limited to this. The position adjustment jig 10 may be fixed on the upper flange BM4 of the beam BM, for example, in a placement process before the alignment process.

Furthermore, in the embodiment described above, the position adjustment jig 10 was described as being attached to the upper surface of the upper flange BM4 to align the end of the beam BM downward with respect to the column PL, but the position adjustment jig 10 is not limited to this. Not done. The position adjustment jig 10 may be attached to the lower surface of the lower flange BM5 to displace the end of the beam BM upward. Thereby, the beam BM can be aligned upward with respect to the pillar PL.

In addition, in the embodiment described above, the alignment of the column PL and the beam BM has been explained, but when the column PL is erected on the foundation of the building, the column base (first construction member) PL4 of the column PL is , a position adjustment jig 10 may be used for positioning with respect to the cloth foundation (second construction member) BS.
With reference to FIGS. 11 and 12, the process of aligning the column base PL4 and the cloth foundation BS will be described.

FIG. 11 shows the column base PL4 and the cloth foundation BS before alignment. In FIG. 11, the pillar PL is lifted from above by a lifting device (not shown) such as a crane truck. Column pedestal PL4 is temporarily fixed to a column pedestal foundation (not shown) located below base plate BP fixed with anchor bolt AB.

FIG. 12 shows a state in which the position adjustment jig 10 is placed on the corner portions of two cloth foundations BS extending in directions perpendicular to each other. As described above, the position adjustment jig 10 has the first distance changing member 11 and the second distance changing member 14, and the first upright plate 12b and the second upright plate 15b are connected to the cloth foundation BS. It is placed so as to be in contact with the tip surface.
The operator can change the distance between the column base PL4 and the cloth foundation BS by rotating the first movable member 13 and the second movable member 16. Thereby, the temporarily fixed column base PL4 can be displaced to an appropriate position and then permanently fixed. Further, a protection plate 17 is provided below the column base PL4. Therefore, it is possible to suppress damage such as deformation of the column base 4 caused by the first movable member 13 and the second movable member 16.
