DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

The joint structure between a column and a beam according to the present invention is a composite beam 1 obtained by superimposing a wooden board 4 on a flange 3 of an H-section steel 20.
On the other hand, a connection plate 10 is erected on the substrate 9 to form a connection fitting 11. The substrate 9 is placed on the wooden plate 4, and a bolt 5 projecting from the back surface of the flange 3 to the wooden plate 4 is screwed to the substrate 9. The end face of the pillar 2 is brought into contact with the substrate 9, and the fastener 12 is inserted into the pillar 2 and the connection plate 10 at a substantially right angle to join the two.

As described above, according to the joint structure of the column and the beam of the present invention, the pulling force applied to the column 2 is applied to the substrate 9, and the substrate 9 is screwed with the bolt 5. Through which the H-beam 20 of the composite beam 1 bears. In this way, damage to the xylem is prevented. A nut 17 is welded to the substrate 9 so that the bolt 5 can be easily screwed. Therefore, the bolt 5 is screwed to the nut 17.

In the embodiment shown in FIG. 1, a connection plate 10 is provided upright at the center of the substrate 9 to form a connection fitting 11, and the connection plate 10
Is inserted into a groove 13 provided on an end face of the column 2, and a fastener 12 as a pin is inserted from the column 2 into the connection plate 10.

Reference numeral 15 denotes an insertion hole for the fastener 12 provided on the column 2, and 16 denotes a fastener 1 provided on the connection plate 10.
2 is the insertion hole. The fastener 12 is inserted through the insertion holes 15.16 to join the column 2 and the composite beam 1.

A nut 17 is welded to the back surface of the substrate 9 so that the bolt 5 can be easily screwed. Therefore,
The bolt 5 is screwed to the nut 17.

In the embodiment shown in FIG. 2, a connection plate 10 is erected on one side of a substrate 9 to form a connection fitting 11, and a bolt 14 protruding from a wooden board 4 is provided on an end face of a pillar 2 in a hole 14 And the connecting plate 10 is brought into contact with the side surface of the pillar 2 and the fastener 1 such as a nail is inserted.
2 is driven into the pillar 2 from the connection plate 10.

The substrate 9 has a nut 17 welded to an insertion portion of the bolt 5 so that the bolt 5 can be easily screwed. Therefore, the bolt 5 is screwed into the nut 17 and the tip is inserted into the hole 14 provided on the end face of the pillar 2.

In any of the above-described embodiments, the flange 3 of the H-section steel 1 and the wooden board 4 are integrated with each other because the bolts 5 protruding from the wooden board 4 are screwed into the base plate 9. 11 has an advantage that it also serves as a fastener for the flange 3 of the H-shaped steel 1 and the wooden board 4.

[0016]

As described above, according to the joint structure of the column and the beam of the present invention, the pulling force applied to the column 2 is applied to the substrate 9,
Since the board 9 is screwed with the bolt 5, the bolt 5
Through which the H-beam 1 of the composite beam 1 bears. In this way, damage to the xylem is prevented.

In any of the above embodiments,
Since the flange 3 of the H-shaped steel 1 and the wooden board 4 are integrated with each other by screwing the bolts 5 protruding from the wooden board 4 to the board 9, the connecting fitting 11 is connected to the flange 3 of the H-shaped steel 1 and the wooden board 4. There is an advantage that it also serves as the fastening metal.
