FIG. 15 is a trihedral view showing the top spacer cover 35.

The top side connecting member (first connecting member) 30 is a metal fitting for connecting the upper end portion 11u of the column group 10 and the left and right end portions 21u, 21v of the beam group 20 at regular intervals along the Y direction.
The top connection member 30 is a combination of the top joint 31 (31A, 31B), the top spacer 34, the top spacer cover 35, and the demon nut 36.
In this embodiment, since wood and resin are used for the column group 10 and the beam group 20, joint reinforcement rings 32 and 33 are also used as reinforcing metal fittings.

The top-side joint (first joint tool) 31 is an aluminum die-cast part, and includes a substantially rhomboid insertion portion 31d, a substantially rectangular flange 31f disposed at one end of the insertion portion 31d, and an insertion portion 31d sandwiching the flange 31f. Is provided with a U-shaped projecting portion 31g projecting on the opposite end side. The U-shaped protrusion 31g is arranged so as to open upward.
The protruding length of the insertion portion (one end) 31d is, for example, 14 mm, which is approximately half the thickness of the first support column 11, the second support column 12, and the beam 21.
The protruding length (including the thickness of the flange 31f) of the protruding portion (the other end) 31g is 47 mm, for example, and is approximately the distance (for example, 95 mm span) between the first column 11, the second column 12 and the beam 21 in the Y direction. It is half.

In addition, what formed the insertion part through-hole 31h in the insertion part 31d is called the top side joint 31A, and what formed the insertion part tap hole 31j in the insertion part 31d is called the top side joint 31B.

The joint reinforcement rings (first reinforcement rings) 32 and 33 are aluminum extrusions formed in a square ring shape in cross section.
The joint reinforcement rings 32 and 33 are fitted into the top side joint mounting holes 11h of the first column 11 and the second column 12 or the right side joint mounting holes 21h and the left side joint mounting holes 21i of the beam 21. Further, the joint reinforcement ring members 32 and 33 are fitted on the insertion portion 31d of the top joint 31 (31A, 31B) with substantially no gap. That is, the joint reinforcement ring members 32 and 33 are interposed between the top joint 31 and the first support column 11, the second support column 12, or the beam 21. As a result, the joint reinforcement rings 32 and 33 prevent the first support column 11, the second support column 12, or the beam 21 from being cracked due to the load acting on the top side joint 31.
The thickness of the joint reinforcing ring 32 in the Y direction is the same as the thickness of the first support column 11 and the beam 21, and is attached to the top side joint mounting hole 11h, the right side joint mounting hole 21h, or the left side joint mounting hole 21i (inside Fitted).
The joint reinforcing ring 33 is about half as thick as the joint reinforcing ring 32 in the Y direction, and is attached (internally fitted) only to the top joint fitting hole 11 h of the second support column 12.

The top spacer (first spacer) 34 is an aluminum extruded material formed in a U-shaped cross section, and has a length (for example, 89 mm) approximately twice as long as the protrusion 31 g of the top joint 31. That is, it is almost the same as the distance (for example, 95 mm span) of the first support column 11, the second support column 12, and the beam 21 in the Y direction.
The top spacer 34 is arranged so that the U-shape opens downward.
The protrusion 31g of the top joint 31 is accommodated in the U-shaped interior of the top spacer 34 (the space surrounded by the bottom 34a and the pair of side walls 34c). The distance between the pair of side walls 34 c of the top spacer 34 is the same as the width of the protrusion 31 g of the top joint 31. The height of the pair of side walls 34c is higher than the protruding portion 31g, and a side wall engaging groove 34d is formed inside the tip of the side wall 34c.
The bottom 34a is provided with two bottom tap holes 34b.

The top spacer cover 35 is a plate-like aluminum extruded material formed in a U-shaped cross section, and has the same length as the top spacer 34.
The width of the main surface 35 a of the top spacer cover 35 is the same as the distance between the pair of side walls 34 c of the top spacer 34. Side wall engaging claws 35 c are formed on the outer ends of the pair of side walls 35 b of the top spacer cover 35.

  The assembling method of the top side connecting member 30, that is, the procedure for connecting the upper end portion 11u of the column group 10 and the left and right end portions 21u, 21v of the beam group 20 is as follows.

  First, the joint reinforcing ring 32 is fitted into the top side joint mounting hole 11 h of the first support column 11. Similarly, the joint reinforcing ring 33 is fitted into the top side joint mounting hole 11 h of the second support column 12. Further, the joint reinforcing ring 32 is fitted into the right joint mounting hole 21h and the left joint mounting hole 21i of the beam 21.

Next, the protruding portion 31g of the top joint 31A is inserted into the joint reinforcing rings 32 and 33 fitted in the first support column 11, the second support column 12, and the beam 21.
Specifically, of the pair of main surfaces 11 s of the first support column 11, the insertion portion 31 d of the top joint 31 </ b> A is connected to the joint reinforcement ring 32 from the rear side (+ Y direction) to the front side (−Y direction). Insert against. At this time, the protrusion 31g of the top joint 31A is inserted so that the U-shape opens upward. Similarly, the insertion portion 31d of the top joint 31A is inserted into the two joint reinforcement rings 33 fitted in the beam 21.
Further, the insertion portion 31 d of the top side joint 31 </ b> A is inserted into the joint reinforcing ring 33 internally fitted to the four second struts 12.

Further, the protrusion 31g of the top side joint 31B is inserted into the joint reinforcing ring 32 fitted inside the first support column 11 and the beam 21.
Specifically, of the pair of main surfaces 11s of the first support column 11, the insertion portion 31d of the top joint 31B is connected to the joint reinforcement ring 32 from the front side (−Y direction) to the rear side (+ Y direction). Insert against. At this time, the protrusion 31g of the top joint 31B is inserted so that the U-shape opens upward. Similarly, the insertion portion 31d of the top joint 31B is inserted into the two joint reinforcing rings 33 fitted inside the beam 21.

  Further, the demon nut 36 is inserted and fixed in the through holes 11m formed in the four second columns 12. The demon nut 36 is inserted from the main surface 11s on the side opposite to the main surface 11s in which the top side joint mounting hole 11h is formed.

Next, the two top joints 31 (31A, 31B) mounted on the first support column 11 and the beam 21 are fastened with hexagon socket head cap screws.
Specifically, a hexagon socket head cap screw is inserted into the insertion portion through hole 31h of the protrusion 31g of the top joint 31A attached to the first support column 11, and the insertion portion tap hole 31j of the protrusion 31g of the top joint 31B is inserted. Screw together. As a result, the flange 31f of the top joint 31A and the flange 31f of the top joint 31B come into contact with and sandwich the pair of main surfaces 11s, so that the top joints 31A and 31B are firmly fixed to the first support column 11. Moreover, since the insertion part 31d of the top side joint 31 and the top side joint attachment hole 11h of the 1st support | pillar 11 are formed in substantially regular rhombus (polygon) instead of a column shape, top side joint 31A, 31B is 1st. There is no rotation with respect to the column 11.
Similarly, the top joints 31A and 31B attached to the beam 21 are fastened and fixed by hexagon socket head bolts.

  In the four second struts 12, a hexagon socket head cap screw is inserted into the insertion portion through hole 31h of the protruding portion 31g of the top joint 31A attached to one main surface 11s and screwed into the tap hole of the demon nut 36. To do. As a result, the top joint 31A and the demon nut 36 are firmly fixed to the first support 11 because the flange 31f of the top joint 31A and the flange 36f of the demon nut 36 abut against and sandwich the pair of main surfaces 11s. .

Next, the top joints 31 fixed to the adjacent members (the first support column 11, the second support column 12, and the beam 21) are abutted (facing).
For example, the protrusion 31 g of the top joint 31 of the first support column 11 and the protrusion 31 g of the top joint 31 of the beam 21 are abutted. And the top side spacer 34 is covered from the upper side with respect to the two protrusion parts 31g which faced each other. Further, hexagon socket head cap screws are inserted into the projecting portion through holes 31i of the two projecting portions 31g and screwed into the two bottom tap holes 34b of the bottom portion 34a of the top spacer 34, respectively. Thereby, the top joint 31 of the first support column 11 and the top joint 31 of the beam 21 are connected and fixed to the top spacer 34.
Further, both ends of the top spacer 34 in the length direction (Y direction) are in contact with the flange 31f of the top joint 31 of the first support column 11 and the flange 31f of the top joint 31 of the beam 21, respectively. The distance between the column 11 and the beam 21 is defined.

Finally, the top spacer cover 35 is attached to the tips of the pair of side walls 34 c of the top spacer 34. Specifically, the side wall engaging claw 35c formed outside the front end of the side wall 35b of the top side spacer cover 35 is engaged with the side wall engaging groove 34d formed inside the front end of the side wall 34c of the top side spacer 34. Combine.
Thereby, the top side joint 31 and the hexagon socket head cap bolt accommodated in the U-shaped inside of the top side spacer 34 are covered with the top side spacer cover 35, so that the appearance is improved.

By repeating the assembly method of the top-side connecting member 30 described above, the upper end portion 11u of the column group 10 and the left and right end portions 21u, 21v of the beam group 20 are connected to each other.
Thus, the basic configuration of the column beam connection structure 1 is completed.

In the column beam connection structure 1, the first support column 11, the second support column 12, and the beam 21 have the same thickness. Further, joint mounting holes having the same shape (top joint mounting hole 11h, right joint mounting hole 21h, and left joint mounting hole 21i) penetrate through the first column 11, the second column 12, and the beam 21 in the thickness direction. Formed as follows. And the top side joint 31 of the top side connection member 30 is mounted | worn in common with these joint attachment holes. Furthermore, the top side spacers 34 of the top side connecting members 30 connect the top side joints 31 to each other.
With such a configuration, it is possible to arbitrarily and easily change the arrangement order of the first support columns 11 and the beams 21 in the Y direction. Moreover, the number of the 1st support | pillar 11 and the beam 21 can be increased / decreased arbitrarily and easily.
In the Y direction, the first support columns 11 may be arranged adjacent to each other, or the beams 21 may be arranged adjacent to each other. The first support columns 11 and the beams 21 may be arranged regularly or irregularly.
The arrangement order of the first support columns 11 and the beams 21 may be determined in consideration of the overall balance of the column beam connection structure 1.
